The disclosures of each of the requests 61 / 349,737; 61 / 353,126;
61 / 356,499; 61 / 407,363; 61 / 436,490 and 61 / 436,545 are hereby incorporated by reference in their entirety for all purposes. BACKGROUND OF THE INVENTION [002] The present invention generally relates to electrical input / output connectors, such as audio connectors and data connectors.
[003] Standard audio connectors or plugs are available in three sizes according to the outer diameter of the plug: a 6.35 mm (1/4) plug, a miniature 3.5 mm plug (1 / 8) and a 2.5 mm (3/32) subminiature plug. Standard plugs include multiple conductive regions that extend along the length of the connectors into different parts of the plug, such as the tip, cap and one or more intermediate parts between the tip and cap resulting in the connectors that are often referred to as TRS connectors (tip, ring and cap).
[004] Figures 1A and 1B illustrate examples of audio plugs and 20 equipped with three and four conductive parts, respectfully. As shown in Figure 1A, plug 10 includes a conductive tip 12, a conductive cap 16 and an electrically conductive ring 14
Petition 870190096258, of 26/09/2019, p. 4/104
2/88 insulated from tip 12 and cap 16 by insulating rings 17 and 18. The three conductive parts 12, 14, 16 are for the left and right audio channels and a ground connection. Plug 20, shown in Figure 1B, includes four conductive parts: a conductive tip 22, a conductive cap 26 and two conductive rings 24, 25 and is then sometimes referred to as a TRRS connector (tip, ring, ring, cap ). The four conductive parts are electrically isolated by insulating rings 27, 28 and 29 and are typically used for the left and right audio, microphone and earthing signals. As evident from Figures 1A and 1B, each of the audio plugs 10 and 20 is independent of the orientation. That is, the conductive parts completely surround the connector forming 360 degree contacts such that there is no top, bottom or side apart from the plug part of the connectors. [005] When plugs 10 and 20 are miniature 3.5 mm connectors, the outer diameter of the conductive cap 16, 26 and conductive rings 14, 24, 25 is 3.5 mm and the insertion length of the connector is 14 mm. For 2.5 mm subminiature connectors, the outer diameter of the conductive cap is 2.5 mm and the insert insertion length is 11 mm. Such TRS and TRRS connectors are used in many commercially available MP3 players and smartphones, as well as other electronic devices. Electronic devices such as MP3 players and smartphones are continually being designed to be thinner and smaller and / or to include video displays with screens that are as wide as close to the outer edge of the devices as possible. The diameter and length of the current 3.5 mm and even 2.5 mm audio connectors are limiting factors in the manufacture of such smaller and thinner devices and in the fact that they allow the displays to be wider for a given form factor.
[006] Many standard data connectors are also available
Petition 870190096258, of 26/09/2019, p. 5/104
3/88 only available in sizes that are limiting factors for making portable electronic devices smaller. In addition and in opposition to the TRS connectors discussed above, many standard data connectors require that they be attached to a corresponding connector in a single specific orientation. Such connectors can be referred to as polarized connectors. As an example of a polarized connector, Figures 2A and 2B depict a micro USB connector 30, the smallest of the USB connectors currently available. The connector 30 includes a body 32 and a metallic liner 34 that extends from the body 32 and can be inserted into a connector of the corresponding receptacle. As shown in Figures 2A, 2B, the liner 34 has angled corners 35 formed on one of its bottom plates. Similarly, the receptacle connector (not shown) with which the connector 30 joins has an insertion opening with corresponding angled coupling features that prevent the liner 34 from being inserted into the receptacle connector in the wrong way. That is, it can only be inserted one way, in an orientation in which the angled parts of the liner 34 align with the corresponding angled coupling parts in the receptacle connector. It is sometimes difficult for the user to determine when a polarized connector, such as connector 30 is oriented in the correct insertion position.
[007] Connector 30 also includes an inner cavity 38 in the liner 34 along with the contacts 36 formed in the cavity. Cavity 38 is prone to collect and retain debris in the cavity which can sometimes interfere with signal connections to contacts 36. Also, and in addition to the orientation issue, even when connector 30 is properly aligned, the Connector insertion and extraction is not accurate, and it may feel inconsistent. Furthermore, even when the connector is fully inserted,
Petition 870190096258, of 26/09/2019, p. 6/104
4/88 it may have an undesirable degree of oscillation which can result in either a faulty connection or a break.
[008] Many other commonly used data connectors, including standard USB connectors, mini USB connectors, FireWire connectors, as well as many of the company's proprietary connectors used with common portable media electronics, suffer from some or with all these deficiencies or similar deficiencies.
BRIEF SUMMARY OF THE INVENTION [009] Various embodiments of the invention pertain to plug connectors and receptacle connectors that are improved through some or all of the deficiencies described above. Other embodiments of the invention pertain to methods of making such a plug and / or such receptacle connectors as well as electronic devices that include such connectors. The modalities of the invention are not limited to any particular type of connector and can be used for numerous applications. Some modalities, however, are particularly well suited for use as audio connectors and some modalities are particularly well suited for data connectors.
[0010] In view of the disadvantages in the currently available audio and data connectors, as described above, some embodiments of the present invention relate to audio and / or data plug connectors that have a reduced plug length and thickness, intuitive insertion orientation and a smooth, consistent feel when inserted and extracted from its corresponding receptacle connector. In addition, some types of plug connectors according to the present invention have external contacts instead of internal contacts and do not include a cavity that is prone to collect and retain debris.

[0086] Figure 60 is a simplified illustrative block diagram of a suitable electronic media device in which the modalities of the invention can be incorporated or used with it; and [0087] Figure 61 depicts an illustrative rendering of a particular embodiment of an electronic media device suitable for use with the embodiments of the present invention. DETAILED DESCRIPTION OF THE INVENTION [0088] The present invention will now be described in detail with reference to certain embodiments of it as illustrated in the attached drawings. In the following description, numerous specific details are established in order to provide a complete understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention can be practiced without some or all of these specific details. At other times, the well-known details have not been described in detail in order not to unnecessarily obscure the present invention.
[0089] In order to better observe and understand the present invention, first, reference is made to Figures 3A to 3C, which are simplified top, side and front views, respectively, of a plug connector 40 according to an embodiment of the present invention. The connector 40 includes a body 42 and a part of the tongue 44. A cable 43 is attached to the body 42 and the part of the tongue 44 extends away from the body 42 in a direction parallel to the length of the connector 40. The tongue 44 is dimensioned to be inserted into a connector of the corresponding receptacle during a joining event and includes a first contact region 46a formed on a first major surface 44a and a second contact region 46b (not shown in Figures 3A to 3C) formed on a second surface greater 44b opposite surface 44a. A plurality of contacts (not shown
Petition 870190096258, of 26/09/2019, p. 10/204
18/88 in Figures 3A to 3C) can be formed in each of the contact regions 46a and 46b such that, when the tongue 44 is inserted into a connector of the corresponding receptacle, the contacts in the regions 46a, 46b are electrically coupled to the contacts on the receptacle connector. In some embodiments, the plurality of contacts are self-cleaning sliding contacts that, after initially making contact with a receptacle connector, the contact during a junction event, slides beyond the contact of the receptacle connector with a sliding motion before reaching a desired final contact position.
[0090] The tongue 44 also includes the first and second opposite side surfaces 44c, 44d which extend between the first and second major surfaces 44a, 44b. Although the tongue 44 is shown in Figures 3A to 3C as having a substantially rectangular and substantially flat shape, in some embodiments of the invention, the first and second major surfaces 44a, 44b may have convex or concave curvatures compatible with them or may have a compatible recessed region centrally located between the sides of the tongue 44. The contact regions 46a and 46b can form in the recessed regions and the recessed regions can, for example, extend from the distal tip of the tongue 44 all the way to the base 42 or it may extend over only part of the length of the tongue 44 (for example, between ½ to ¾ of the length of the tongue) ending in a short point of the base 42. The side surfaces 44c and 44d may also have convex curvatures or compatible concave.
[0091] Generally, the shape and curvature of surfaces 44a and
44b mirror each other, as do the shape and curvature of surfaces 44a and 44b, according to the dual orientation design of connector 40, as described below. Additionally, very

19/88 although Figures 3A to 3C show surfaces 44c, 44d as having a width significantly less than that of surfaces 44a, 44b (for example, less than or equal to half the width of surfaces 44a, 44b), in some embodiments of the invention, the side surfaces 44c, 44d have a width that is relatively close to or even equal to or greater than that of the surfaces 44a, 44b.
[0092] Figures 4A to 4C are simplified frontal plan views of the modalities of the connector 40 in which the body 42 and / or the tongue 44 has different shapes in cross section. For example, in Figure 4A, the larger surfaces 44a and 44b are slightly convex, while in Figures 4B and 4C, the side surfaces 44c and 44d are rounded. Furthermore, Figure 4C depicts an example of a connector that has the recessed regions 45a and 45b formed on the larger surfaces 44a and 44b, respectfully, of the tongue 44. The recessed regions extend from the distal end of the tongue 44 along a part of the tongue length 44 and are centrally located between the side surfaces 44c and 44d. A person skilled in the art will understand that Figures 3C and 4A to 4C are examples of cross-sectional shapes suitable for body 42 and tongue 44 and that many other cross-sectional shapes can be used for each of body 42 and the tongue 44 in various embodiments of the invention.
[0093] In some embodiments, one or more earthing contacts can form on the side surfaces. For example, Figures 3A and 3B show an earthing contact 47a formed on the first side surface 44c and an earthing contact 47b formed on the second side surface 44d opposite the earthing contact 47a. As another example, one or more earthing contacts can be formed on the end surface 44 and at the distal end of the connector 40 in addition to the earthing contacts

47a, 47b or instead of them. In some embodiments, each of the one or more earthing contacts can be formed on the part or from the part of an external part of its respective lateral surface. In other embodiments, the one or more earthing contacts can be formed inside and / or as part of a pocket, indentation, chamfer or similar recessed region formed on each of the side surfaces 44c, 44d which are operatively engaged with a mechanism into a connector on the corresponding receptacle, as described in detail below.
[0094] Body 42 is usually the part of connector 40 that a user will hold when inserting or removing connector 40 from a connector on the corresponding receptacle. The body 42 can be made up of a variety of materials and, in some embodiments, is made of a dielectric material, such as a thermoplastic polymer formed in an injection molding process. Although not shown in Figures 3A or 3B, a part of the cable 43 and a part of the tongue 44 can extend within the body 42 and be enveloped by it. Also, the electrical contact for the contacts in each of the regions 46a, 46b can be made for the individual wires in the cable 43 in the body 42. In one embodiment, the cable 43 includes a plurality of individual insulated wires, one for each contact in the regions 46a and 46b, which are soldered to the connection islands on a printed circuit board (PCB) housed in the body 42. Each connection island on the PCB is electrically coupled to a corresponding individual contact within one of the contact regions 46a or 46b .
[0095] The tongue 44 can also be made from a variety of materials including metal, dielectric or a combination of them. In some embodiments, the tongue 44 includes a frame made primarily or exclusively of a metal, such as stainless steel, and the contact regions 46a and 46b are formed in the frame. In some other ways
Petition 870190096258, of 26/09/2019, p. 10/23
21/88 dalities, the tongue 44 includes a frame made primarily or exclusively of a dielectric material, such as a ceramic or an elastomeric material. For example, tongue 44 may be a ceramic base that has contacts printed directly on its surfaces.
[0096] In the embodiment illustrated in Figures 3A and 3B, the body 42 has a rectangular cross section that is generally compatible in shape, but is slightly larger than the cross section of the tongue 42. As discussed with respect to Figures 4A to 4C, body 42, however, can be of a variety of shapes and sizes. For example, the body 42 may have a rectangular cross section with rounded or angled edges (referred to herein as a generally rectangular cross section), a circular cross section, an oval cross section, as well as many other suitable shapes. In some embodiments, both the body 42 and the tongue 44 of the connector 40 have the same shape in cross section and have the same width and height (thickness). As an example, the body 42 and the tongue 44 may combine to form a substantially flat uniform connector in which the body and tongue appear as one. In still other embodiments, the cross section of the body 42 has a different shape than the cross section of the tongue 44. As an example, the body 42 can have curved surface and bottom and / or lateral curved surfaces while the tongue 44 is substantially flat.
[0097] Each of the contact regions 46a, 46b can be centered between the opposite side surfaces 44c, 44d. The individual contacts in the contact regions 46a and 46b can be external contacts positioned on an external surface of the tongue 44 so that some modalities of the connector 40 do not include contacts positioned in an internal cavity in which particles and debris can be

22/88 accumulate. Each of the contact regions 46a and 46b can include one or more contacts that can be made of copper, nickel, brass, a metal alloy or any other suitable conductive material. In some embodiments, contacts can be printed on surfaces 44a and 44b using techniques similar to those used for contacts printed on printed circuit boards.
[0098] Contact regions 46a and 46b can include any number of contacts, from one to twenty or more arranged in a variety of different patterns. Figures 5A to 5H provide different examples of contact arrangements in a contact region 46 according to different embodiments of the invention. As shown in Figure 5A, contact region 46 can include two contacts 51 (1) and 51 (2) that are centered and symmetrically positioned in the contact region. Similarly, Figure 5B depicts a contact region 46 that has three contacts 52 (1) .. 52 (3) centered and symmetrically positioned in the contact region, and Figure 5C depicts a contact region 46 that has four such contacts 53 (1) .. 53 (4).
[0099] Although each of Figures 5A to 5C includes a single row of contacts in region 46, some embodiments of the invention may include two, three or more rows of contacts. As examples, the contact region 46 shown in Figure 5D includes two rows of four contacts 54 (1) .. 54 (4) and 54 (5) .. 54 (8) with each row being centered between the sides of the region of contact and symmetrically spaced with respect to a central line that is transversal to the length of the contact region; Figure 5E shows a contact region 46 provided with a first row of three contacts 55 (1) .. 51 (3) and a second row of four contacts 55 (4) .. 55 (7) positioned in the contact region; and Figure 5F depicts a contact region 46 that has three rows of three contacts for a total of nine contacts 56 (1) .. 56 (9).
[00100] Even though each row of individual contacts in the regions

23/88 contact sions shown in Figures 5A to 5F center the contacts in the row between the sides of the contact region and symmetrically space the contacts with respect to a central line that is transversal to the length of the contact region, in some embodiments of the invention , contacts do not need to be centered in this way. As an example, Figure 5G depicts a contact region 46a that has two contacts 57 (1) .. 57 (2) that are not centered on the contact region. To provide the 180-degree symmetry employed by some embodiments of the invention, a connector that includes the contact region 46a shown in Figure 5G on a larger surface, includes a contact region 46b as shown in Figure 5H on the opposite largest surface that is compatible with contact region 46a. In Figure 5H, contact region 46b and contacts 57 (3) to 57 (4) are shown in dashed lines to represent the position of the contacts when looking from contact region 46a through the connector to contact region 46b.
[00101] Each of the contact regions 46 shown in Figures 5A to 5G is represented by both regions 46a and 46b according to the particular embodiments of the invention. That is, according to an embodiment of the invention, a plug connector 40 includes two contact regions 46a and 46b, each of which includes two contacts as shown in region 46 in Figure 5A. In another embodiment, a plug connector 40 includes contact regions 46a and 46b, each of which includes three contacts as shown in Figure 5B. Still other embodiments of the invention include: a connector 40 provided with contact regions 46a and 46b, as shown in region 46 in Figure 5C; a connector 40 provided with contact regions 46a and 46b, as shown in region 46 in Figure 5D; a connector 40 provided with contact regions 46a and 46b, as shown in region 46 in Figure 5E; a connector 40 provided with contact regions 46a and
Petition 870190096258, of 26/09/2019, p. 10/26
24/88
46b, as shown in region 46 in Figure 5F; and a connector 40 provided with contact regions 46a and 46b, as shown in region 46 in Figure 5G.
[00102] Contacts in regions 46a, 46b can include contacts designed for a wide variety of signals that include power contacts, earthing contacts, analog contacts and digital contacts, among others. In some embodiments, one or more earthing contacts are formed in regions 46a and / or 46b while in other embodiments, earthing contacts are only located at the tip 44e and / or on the side surfaces 44c, 44d of connector 40 in order to save space in contact regions 46a and 46b for power and signal contacts. The arrangements employing the earthing contacts in one or more positions along the peripheral and / or tip side surfaces of the connector 40 instead of in the contact regions 46a and 46b may enable the overall dimension of the connector tongue 44 is less than that of a similar connector that includes earthing contacts in contact regions 46a or 46b.
[00103] The power contacts in regions 46a, 46b can carry signals of any voltage and, as an example, can carry any signals between 2 and 30 volts. In some embodiments, multiple energy contacts are included in regions 46a, 46b to carry energy signals of different voltages that can be used for different purposes. For example, one or more contacts to distribute low current energy at 3.3 volts that can be used to drive accessory devices connected to connector 40 can be included in regions 46a, 46b, as well as one or more contacts to distribute power from high current at 5 volts to charge portable media devices attached to connector 40.
[00104] Examples of similar contacts that may be included
Petition 870190096258, of 26/09/2019, p. 10/274
25/88 in contact regions 46a, 46b include contacts to separate the left and right channels for both the audio output and audio input signals, as well as the contacts for video signals, such as video signals RGB, YPbPr component video signals and others. Similarly, many different types of digital signals can be carried by contacts in regions 46a, 46b including data signals such as USB signals (including USB 1.0, 2.0 and / or 3.0), FireWire (also referred to as IEEE 1394), SATA signals and / or any other type of data signal. Digital signals in contact regions 46a, 46b can also include signals for digital video, such as DVI signals, HDMI signals and Display Port signals, as well as other digital signals that perform the functions that enable the detection and identification of devices or accessories for connector 40.
[00105] In some embodiments, the dielectric material is used to fill between the individual contacts in the contact regions 46a, 46b so that the dielectric material and the contacts form a completely level outer surface of the tongue 44 that provides a smooth and consistent feel across of tongue surfaces 44. Additionally, to improve robustness and reliability, connector 40 can be completely sealed and does not include moving parts.
[00106] The connector 40 can have a double orientation, symmetrical design with 180 degrees that allows the connector to be inserted into a connector of the corresponding receptacle either in a first orientation where the surface 44a is facing upwards or a second orientation in that the surface 44a is rotated 180 degrees and faces downwards. To allow the characteristic independent of the orientation of the connector 40, the tongue 44 is not polarized. That is, tongue 44 does not include a physical key that is configured to mate with a compatible key on a corresponding receptacle connector.
Petition 870190096258, of 26/09/2019, p. 10/284
26/88 correspondingly designed to ensure that the union between the two connectors occurs only in a single orientation. Instead, if the tongue 44 is divided into top and bottom halves along a horizontal plane that divides the center of tongue 44 in two along its width, the physical shape of the upper half of tongue 44 is substantially the same. same as the physical shape of the lower half. Similarly, if tongue 44 is divided into left and right halves along a vertical plane that divides the tongue center in two along its length, the physical shape of the left half of tongue 44 is substantially the same. same as the shape of the right half. Additionally, the contacts can be positioned in the contact regions 46a and 46b so that the individual contacts in the region 46a are arranged symmetrically with the individual contacts in the region 46b located on the opposite side of the tongue 44, and the earthing contacts formed at the tip or on the tongue sides of the connector 44 they can also be arranged symmetrically.
[00107] To better understand and observe the 180 degree symmetrical design of some modalities of the invention, reference is made to Figures 6A and 6B which are simplified views of a first side 44a and a second opposite side 44b, respectively, of a connector plug 50 according to a specific embodiment of the invention which includes four individual contacts formed in each of the contact regions 46a and 46b. For example, as shown in Figure 6A, contact region 46a can include four evenly spaced contacts 53 (1) .. 53 (4) formed in the region. With respect to a central plane 59 that is perpendicular and passes through the middle of connector 50 along its length, contacts 53 (1) and 53 (2) are in a mirrored relationship with contacts 53 (3) and 53 ( 4). That is, the spacing from the center line 59 to the contact 53 (2) is the same
Petition 870190096258, of 26/09/2019, p. 10/29
27/88 that the spacing from the center line 59 to the contact 53 (3). Also, the spacing from the center line 59 to the contact 53 (1) is the same as the spacing from the center line 59 to the contact 53 (4). Each of the pairs of contacts 53 (1), 53 (2) and 53 (3), 53 (4) are also equally spaced from the sides 44c and 44d of the connector with respect to each other and are equally spaced along the tongue length 44 between end surface 44e and body 42.
[00108] Similarly, in Figure 6B the contact region 44b includes the same number of contacts as the region 44a which are also spaced according to the same spacing in the region 44a. Thus, contact region 44b includes four contacts 53 (5) .. 53 (8) spaced in region 46b according to the same outline and spacing as contacts 53 (1) .. 53 (4) in regions 46a. Due to the fact that the outline and spacing of the contacts in the regions 46a and 46b are identical, without any kind of signs or marks on one of the surfaces 44a or 44b, the surfaces and outline of the contact on each of the surfaces 44a, 44b look like the themselves. When connector 50 is inserted into a corresponding receptacle connector, the contacts in regions 46a, 46b will make appropriate electrical contact with the contacts in the receptacle connector in either of the two different orientations (referred to herein as up or down for convenience , but it will be noted that these are relative items intended to connote a 180 degree change in connector orientation only).
[00109] To illustrate further, reference is now made to Figures 7A and 7B, which schematically show a cross-sectional view of plug connector 50 which has four contacts in each of regions 46a, 46b as shown in Figures 6A and 6B inserted into a compatible receptacle 60 connector. The receptacle connector 60 includes a cavity 64 in which the plug connector tongue
Petition 870190096258, of 26/09/2019, p. 10/30
28/88 can be inserted. Four contacts 61 (1) .. 61 (4) extend from an inner surface of the receptacle connector to cavity 64 and four contacts 61 (5) .. 61 (8) extend from the opposite inner surface to cavity 64 in a mirrored and opposite relationship to the contacts 61 (1) .. 61 (4).
[00110] Figure 7A shows that when connector 50 is inserted into cavity 65 in an upward position, contact 53 (1) of the plug connector aligns with contact 61 (1) of the receptacle connector, contact 53 (2) aligns with contact 61 (2), contact 53 (3) aligns with contact 61 (3) and contact 53 (4) aligns with contact 61 (4). Figure 7A also shows that, on the opposite surface, contact 53 (5) aligns with contact 61 (5), contact 53 (6) aligns with contact 61 (6), contact 53 (7) aligns with contact 61 (7) and contact 53 (8) aligns with contact 61 (8). When the plug connector is inserted into the receptacle connector 60 in a downward position, as shown in Figure 7B, each contact on the plug connector still properly lines up with a contact on the receptacle connector. The contacts align differently, however, as follows: contact 53 (5) of the plug connector aligns with contact 61 (1) of the receptacle connector, contact 53 (6) aligns with contact 61 (2), contact 53 (7) aligns with contact 61 (3) and contact 53 (8) aligns with contact 61 (4), while on the opposite surface, contact 53 (1) aligns with contact 61 (5), contact 53 (2) aligns with contact 61 (6), contact 53 (3) aligns with contact 61 (7) and contact 53 (4) aligns with contact 61 (8). In addition, when the plug connector 50 includes the side earthing contacts 53a, 53b, each side contact aligns with a corresponding earthing side contact 61a, 61b of the receptacle connector 60 in either of the two possible insertion orientations , as shown in Figures 7A and 7B.
Petition 870190096258, of 26/09/2019, p. 10/314
29/88 [00111] Thus, regardless of whether the connector 50 is inserted into the receptacle connector 60 in any of the up or down positions, the appropriate electrical contact is made between the contacts on the plug connector and the receptacle connector. The modalities of the invention also belong to a receptacle connector that includes circuit assemblies that change the functionality of its pins based on the orientation of the plug connector. In some embodiments, a reading circuit on the receptacle connector or on the electronic device in which the receptacle connector is housed, can detect the orientation of the plug connector and define the software and / or hardware switches to exchange the internal connections for the contacts on the receptacle connector and properly pair the receptacle connector contacts to the plug connector contacts as appropriate. In some embodiments, the orientation of the plug connector can be detected based on a physical orientation switch (unlike a polarization switch where an orientation switch does not prevent the plug connector from being inserted into the receptacle connector in multiple orientations ) which, depending on the orientation of the plug connector, engages or does not engage with a corresponding orientation contact on the receptacle connector. The circuit assemblies connected to the orientation contact can then determine which of the two possible orientations the plug connector has been inserted into the receptacle connector.
[00112] As an example, reference is now made to Figures 8A to 8C, which show simplified top, bottom and side plan views of a plug connector 70 according to another embodiment of the present invention together with the Figures 9A and 9B, which are simplified schematic views of plug connector 70 inserted into a receptacle connector 80. Connector 70 includes contact regions 46a and 46b formed on the opposite major surfaces of the connector that
Petition 870190096258, of 26/09/2019, p. 10/324
30/88 can contain any reasonable number of contacts. For example, in the particular embodiment shown in Figure 9A, connector 70 is an audio plug connector and each of the contact regions 46a and 46b includes two contacts: a microphone contact and a right audio contact in region 46a, and a left audio contact and an earthing contact in region 46b. When connector 70 is joined to receptacle connector 80, an orientation switch 72 on the plug connector engages (or does not engage) with a corresponding orientation contact 86 on receptacle connector 80.
[00113] The circuitry operatively coupled to the receptacle connector can define the software and / or hardware switches to properly pair the receptacle connector contacts with plug 70 connector contacts. For example, a software switch can be used to exchange the connector male jack contacts for left and right audio depending on the insertion orientation while a hardware switch can be used to exchange the microphone and the earthing contacts of the connector male jacks to be compatible with the contacts of connector 70. In other embodiments, both switches can be implemented in software or both switches can be implemented in hardware. A comparison of Figure 9A to 9B illustrates the change of receptacle contacts depending on whether the orientation contact 86 is engaged (Figure 9B) or not engaged (Figure 9A), in which, for ease of illustration, the contact labels exchanged are underlined and depicted in a larger font.
[00114] As another example, connector 70 can be an audio plug connector with six contacts with each of the contact regions 46a, 46b including three contacts, as shown in Figures 9C to 9D: one microphone contact, one li's first contact
Petition 870190096258, of 26/09/2019, p. 10/334
31/88 dedicated earthing and a right audio contact are in region 46a; while a left audio contact, a second dedicated earthing contact and a second dedicated microphone contact are located in region 46b. The first and second earthing contacts and the first and second microphone contacts line up with the microphone and earthing contacts of the corresponding connector male socket 80 regardless of the connector insertion orientation 70. Thus, this This modality can be performed with a single switch, which can be implemented in software or hardware to change the contacts of the male connector socket to the left and right audio depending on the insertion orientation, which can be detected by the orientation contact 86 on the connector of the connector. receptacle.
[00115] As shown in Figures 8A to 8C, connector 70 may also include retaining features 74a, 74b on opposite side surfaces of the connector. The retention features can operate to attach connector 70 to a connector on the corresponding receptacle, as discussed below with respect to Figures 12A and 12B. Notably, in the embodiment shown in Figures 8A to 8C, the retention feature 74b and the orientation key 72 combine to form a single extended incision on side 44d of connector 70. In other embodiments, the feature (s) of The retention key and the guidance key can be completely separated from each other and even included on separate surfaces. For example, in one embodiment the orientation key 72 can be located on one of the larger surfaces 44a or 44b while the retention features can be located on one or both side surfaces 44c and 44d.
[00116] In other embodiments, the plug connector does not include an orientation switch and the orientation of the connector can instead be detected by the circuit assembly associated with the connector of the
Petition 870190096258, of 26/09/2019, p. 10/34
32/88 corresponding receptacle based on the signals received by the contacts. As an example, various accessories, such as headsets for cell phones, include a microphone and allow a user to perform basic functions, such as setting the earpiece volume and answering and ending calls with the press of a button on the accessory. A single wired serial control card can be used to communicate with the host electronic device and implement this functionality. The board is connected to the microphone contact (for example, contact 112b shown in Figure 14A) and, when the plug connector is inserted into the receptacle's male socket, you can speak to the appropriate circuitry on the male socket connector or host device. On an insertion occasion, the host device sends an Acknowledge signal to the serial control board via the contact on the receptacle connector designated for the microphone and waits for a Reply signal. If a Reply signal is received, the contacts are properly aligned and the audio and other signals can be transferred between the connectors. If no response is received, the host device turns the signals to match the second possible orientation (that is, turns the signals 180 degrees) and repeats the Recognition / Response signal routine.
[00117] In the four-contact mode of a plug connector 70 shown in Figure 9E, the left and right audio contacts are always in physically reversible positions while each of the other two contacts is designed as a microphone contact. In this embodiment, a physical orientation switch on the plug connector, such as switch 72, can be detected by an orientation contact or other appropriate mechanism on the receptacle connector to determine the orientation of the plug, and a hardware or software switch can define receptacle connector contacts as
Petition 870190096258, of 26/09/2019, p. 10/35
33/88 appropriate for the left and right audio to match the plug connector contacts. In the mode of the plug connector 70 shown in Figure 9F, a contact 75 is connected to the base through, for example, a grounding ring 102 (described with reference to Figures 10A to 10B). When the connector is first plugged into a receptacle connector, the circuitry associated with the receptacle connector or the electronic device in which the connector is housed detects the position of the grounded contact and changes the receptacle contacts to an appropriate orientation.
[00118] To facilitate the dual orientation characteristic of certain embodiments of the invention, the contacts in the contact regions 46a, 46b can be arranged such that the contacts proposed in a similar manner are located on opposite sides of the connector tongue in a diagonal arrangement. For example, referring again to Figure 7A, contact 53 (1) is in a diagonal arrangement with contact 53 (5) while contact 53 (2) is in a diagonal relationship with contact 53 (6). Contacts proposed in a similar way are contacts that are designed to carry similar signals. Examples of similarly proposed contact pairs may include, first and second power contacts, left and right audio output contacts, first and second earthing contacts, a pair of differential data contacts, and / or first and second digital contacts. Because of the symmetrical relationship between the contacts, such a diagonal relationship ensures that for each pair of contacts proposed in a similar way in a diagonal relationship, one of the contacts proposed in a similar way is electrically connected to a contact on the receptacle connector that is or dedicated to the particular contact or can be readily switched to that particular contact. As an example, where contacts 53 (1) and 53 (5) are similarly proposed contacts that are dedicated to
Petition 870190096258, of 26/09/2019, p. 10/36
34/88 left and right audio output signals, respectively, when plug connector 50 is inserted into receptacle connector 60, one of the audio output contacts will be in electrical contact with receptacle contact 61 (1) and the another of the audio output contacts will be in electrical contact with the receptacle contact 61 (5) regardless of whether the plug connector is attached to the receptacle connector in an upward or downward insertion orientation. Thus, both receptacle contacts 61 (1) and 61 (5) can be audio contacts that ensure that they are electrically coupled to an audio contact on the plug connector regardless of their insertion orientation.
[00119] Although Figures 7A to 7B depict a particular embodiment of the invention with an even number of contacts in each of the contact regions 46a and 46b, some embodiments of the invention may include an odd number of contacts in each of the regions 46a, 46b. In such embodiments, one of the contacts on each side of the plug connector is a central contact that is centered around the bifurcation line 59a and then meets Alina with a receptacle contact centrally located in both the up and down position. low. The central contacts are not in a diagonal arrangement, but are in a symmetrical arrangement and can be contacts proposed in a similar manner according to some embodiments of the invention.
[00120] Figures 10A and 10B illustrate this aspect of certain embodiments of the invention and depict a plug connector 70 provided with three contacts 52 (1) .. 52 (3) and 52 (4) .. 52 (6) formed in the top and bottom surfaces of tongue 44 of the plug connector, respectively. When the connector tab is inserted into a connector on the corresponding receptacle 80 in an upward position, contacts 52 (1) .. 52 (3) align with contacts 81 (1) .. 81 (3) of the co

When the connector tab is inserted into a receptacle connector 80 in a downward position, contacts 52 (4) .. 52 (6) align with contacts 81 (1) .. 81 (3) of the receptacle connector , respectively, and contacts 52 (1) .. 52 (3) align with contacts 81 (4) .. 81 (6), respectively. In both orientations, the plug connector contacts 52 (2) and 52 (5) align with one of the central contacts on the receptacle 81 (2) or 81 (5).
[00121] Plug connector 40 can be designed to be inserted into a compatible receptacle connector, such as receptacle connector 80, along a geometrical insertion axis. In some embodiments of the invention, at least a part of the plug connector is made of a flexible material so that the connector can readily bend out of the geometry axis. As an example, Figure 11A shows a simplified side cross-sectional view of a connector 90 similar to connector 40 that is intended to be inserted into a receptacle connector along an insertion geometry axis 95. The tongue 44 of connector 90 includes a flexible carrier member 92 that extends the length of tongue 44 along with the contacts (not shown) formed on each of the opposite surfaces 44a, 44b of connector 90 that can flex with carrier member 92. As an example, the contacts they can be part of a flexible circuit that is connected to flexible carrier member 92. Flexible carrier 92 and flexible contacts allow tongue 44 to be curved along a direction 94 in a deformed shape, as shown in Figure 11B when the connector it is joined with a receptacle connector 97 (that is, positioned with an insertion cavity 98 of the receptacle connector) and subjected to tension when pulled in one direction section 96 that intersects the insertion geometric axis
Petition 870190096258, of 26/09/2019, p. 38/104
36/88 tion 95. As soon as the tension is released, the tongue 44 returns to its normal shape shown in Figure 11A. In this way, when connector 90 is pulled out of its receptacle connector when pulling at least partially sideways (for example, along direction 96 as opposed to pulling along geometry axis 95) or in body 42 or in cable (not shown) attached to body 42, plug connector 90 can bend and be pulled out of the receptacle connector instead of joining or eventually breaking.
[00122] In a particular embodiment, the flexible carrier 92 is a sheet of superelastic material, such as nitinol (a nickel and titanium alloy present in approximately equal amounts) and the flexible contacts are part of a flexible circuit adhered to the superelastic sheet. Nitinol alloys exhibit an elasticity of 10 to 30 times that of common metal, which allows them to be flexible under very high tension without breaking. The flexible circuit can include, for example, metallic contact screen printed on a thin layer of polyimide or PEEK (polyester ether ketone). The flexible circuit can be made of two separate pieces, each of which is directly adhered to one side of the nitinol sheet, or it can be a single piece wrapped around the perimeter of the nitinol sheet or made into a cover that fits over the sheet nitinol.
[00123] The modalities of the invention that include its flexibility characteristic are not limited to the use of any particular superelastic material and can instead use any material that reversibly deforms at very high stresses and returns to its original shape when loading is removed without requiring a temperature change to regain its original shape. Some embodiments of the invention may use flexible materials for carrier 92 that are not superelastic. For example, carrier 92 or tongue 44 itself can be made of an elastomer
Petition 870190096258, of 26/09/2019, p. 10/39
37/88 or polyurethane in some modalities.
[00124] When the connector plug 90 is engaged with a connector of the corresponding receptacle and extracted at an angle to the geometric axis of insertion, more energy is typically applied at the base of the connector than at its tip. To address this discrepancy, in some modalities the flexibility of the carrier 92 varies along the length of the carrier so that, for example, it is more flexible near the base or proximal end of the connector where it meets the body 42 and less flexible near the distal end of the connector. The flexibility can be varied in this way, among other techniques, by varying the materials along the length of the connector, by varying the thickness of the flexible carrier along its length or by varying the shape of the flexible carrier along its length or any combination of these approaches. For example, in one embodiment, carrier 92 may include a superelastic sheet near its base and a polyurethane sheet near its distal end. Superelastic and polyurethane sheets can overlap and be bonded together in an area between the proximal and distal ends. In a particular embodiment, carrier 92 comprises two sheets of polyurethane near the distal end of tongue 44 and a single sheet of nitinol near the base of tongue 44 where the tongue joins body 42. At one point, approximately one third of the connector length from the distal end, the nitinol sheet is sandwiched between the two polyurethane sheets for part of the length.
[00125] Reference is now made to Figures 12A and 12B, which are simplified top and side views of a plug connector 100 according to another embodiment of the invention. Plug connector 100 includes many of the same features as plug connector 40, but additionally includes a cap 102, and first and
Petition 870190096258, of 26/09/2019, p. 10/40
38/88 according to retention features 104a and 104b, respectively, close to a distal end of the connector. The cover 102 can be made of a metal or other conductive material and can extend from the distal tip of the connector 100 along the side of the connector towards the body 42 be complete or partially surrounding the contacts formed in the contact regions 46a and 46b in the X and Y directions. Cap 102 can be grounded to minimize interference that may otherwise occur on connector contacts 100. In one embodiment, cap 102 can be a U-shaped frame that has a thickness which is equivalent to the thickness (T) of connector 100. In another embodiment, cover 102 covers the entire tongue 44, except the contact regions 46a, 46b and then defines the shape of tongue 44. Cover 102 is , sometimes referred to herein as a grounding ring and these two terms are intended to be used interchangeably. The lid 102 can be formed in a variety of ways and, in one embodiment, it can be cast into a mold from a metal, such as stainless steel, which can be slid over the end of the tongue of connector 44 and attached to it, thus, partially or totally surrounding the contact regions 46a and 46b at the tip and sides of the connector.
[00126] Figures 13A and 13B show two different modalities of the lid 102. In Figure 13A, the lid 102 is a U-shaped frame that can be secured or slid by the end of the connector. The lid 102 includes side parts 102a, 102b which can have varying lengths in different embodiments. In some embodiments, sides 102a, 102b extend past contact regions 46a, 46b all the way to body 42 of the connector. In other embodiments, the sides may extend past contact regions 46a, 46b, but not all the way to body 42 (as shown in Figure 12A); can extend exactly
Petition 870190096258, of 26/09/2019, p. 41/104
39/88 to the end of the contact regions 46a, 46b or can be relatively short and extend only partially along the length of the contact regions. The contact regions 46a, 46b extend between the opposite sides 102a, 102b. In still other embodiments, the earthing cap or ring 102 defines the outer shape of the tongue 44 that completely surrounds the contact regions 46 on the outer surfaces of the connector, as shown in Figure 13B.
[00127] Referring again to Figures 12A and 12B, the retention features 104a, 104b form on opposite sides of the connector 100 and are part of a retention system that includes one or more features in the plug connector that are adapted to engage with one or more features on the corresponding receptacle connector to secure the connectors together when the plug connector is inserted into the receptacle connector. In the illustrated embodiment, the retention features 104a, 104b are semicircular indentations on the side surfaces of the tongue 44 that extend from surface 44a to surface 44b. Retention features can be widely varied and can include angled indentations or chamfers, pockets that are formed only on the side surfaces and do not extend to any of the surfaces 44a, 44b in which the contact regions 46a, 46b are formed, or other regions lowered. The retention features are adapted to engage with a retention mechanism on the receptacle connector that can be varied in similar and wide ways. The retention mechanism (s) can, for example, be one or more springs that include a tip or surface that fits in the indentations 104a, 104b, one or more spring-activated detectors, or latching mechanisms similar. The retention system, which includes retention features 104a, 104b and the corresponding retention mechanism on the receptacle connector,
Petition 870190096258, of 26/09/2019, p. 42/104
40/88 can be designed to provide specific insertion and extraction energies, such that the holding energy required to insert the plug connector into the receptacle connector is higher than the extraction energy required to remove the plug connector from the receptacle connector.
[00128] Even though the retention features 104a, 104b are shown in Figures 12A and 12B as having a female conjugate feature and the retention mechanism has been described above as having a male feature that is moved to the retention features 104a, 104b, in other modalities these roles may differ. For example, in one embodiment, the retention features 104a, 104b can be spring-driven projections that engage with a female retention mechanism on the receptacle connector. In still other embodiments, one of the resources 104a, 104b can be oriented as a male while the other of the resources 104a, 104b is oriented as a female. In other embodiments, other retention mechanisms can be used such as mechanical or magnetic couplings or orthogonal insertion mechanisms. In addition, although the retention features 104a and 104b are shown in Figures 12A and 12B as being formed in the metal cap 102, in the embodiments of the invention that do not include a metal cap or earthing ring, the retention features can be formed in any structure or material that constitutes the tongue 44.
[00129] Retention features 104a, 104b can also be located in a variety of positions along connector 100 including along the side surfaces of tongue 44 and / or the top and bottom surfaces of tongue 44. In some embodiments , the retention features 104a, 104b can be located on a front surface 42a of the body 42 and be adapted to engage with a retention mechanism located on a fron outer surface
Petition 870190096258, of 26/09/2019, p. 43/104
41/88 such as the receptacle connector. In the embodiment illustrated in Figures 12A and 12B, the retaining features 104a, 104b are positioned on the last third of the length of the tongue 44. The inventors have determined that positioning the retaining features and the corresponding engagement mechanism on the receptacle connector near the end of the plug connector helps to better secure the connector from the sides when it is in a engaged position on the receptacle connector.
[00130] The description of the various modalities of the invention set out above with reference to Figures 3A to 13B describes numerous different characteristics, aspects and variations of different modalities of the invention. To gain a greater understanding of the invention, numerous additional modalities and examples of the invention that include both the audio connector and data connector modalities are discussed below, which include some or all of the features already mentioned, as well as the additional features. The various modalities discussed below include many characteristics in common with the modalities already discussed and with each other. As a matter of convenience, such common characteristics are often, but not always, referred to with the same numerical reference. In addition, in the discussion below, the reference to a connector provided with a specific number of contacts generally refers to the number of contacts on the opposite major surfaces of the connector and does not include any earthing contacts or any other formed on the tip and / or connector sides.
[00131] Figure 14A is a simplified perspective view of a four-contact plug connector 110 according to an embodiment of the invention while Figures 14B to 14D are simplified top, side and bottom plan views, respectively, of the connector 110. As shown, connector 110 includes a tongue
Petition 870190096258, of 26/09/2019, p. 44/104
42/88 extending from the body 42. The tongue 44 has a larger front surface 44a on which two contacts 112a and 112b are positioned and a larger rear surface 44b on which two contacts 112c and 112d are located.
[00132] The contacts can be made of copper, nickel, brass, a metal alloy or any other suitable conductive material. The spacing is consistent between each pair of contacts 112a, 112b and 112c, 112d providing 180 degree symmetry so that plug connector 110 can be inserted into a corresponding receptacle connector in either of the two orientations. In a particular embodiment, connector 110 is an audio plug connector and contact 112a is a left audio contact, contact 112b is a microphone contact, contact 112c is a right audio contact and contact 112d is a second redundant microphone contact. The modalities of the invention are not limited to any particular contact arrangement, however, and can be assigned to other signals. In another embodiment of the four-contact plug connector, connector 110 is a data connector and each of the contacts 112a through 112d can be assigned to the data signals. For example, contacts 112a and 112b can be assigned to a first pair of differential data signals (for example, data transmission) while contacts 112c and 112d can be assigned to a second pair of differential data signals (for example, receiving data). In other embodiments, contacts 112a through 112d can be assigned to a wide variety of other types of signals.
[00133] The metallic earthing ring 102 defines the shape of the tongue 44 and surrounds the contacts 112a to 112d along an external periphery of the tongue. The two semicircular chamfers 104a and 104b, are formed in the earthing ring 102 and located on opposite sides 44c and 44d of the tongue near its distal end.
Petition 870190096258, of 26/09/2019, p. 45/104
43/88
In operation, the tongue 44 is inserted into a receptacle connector (for example, shown in Figures 28A to 28C) until the chamfers 104a and 104b operatively engage with a retaining mechanism, such as a spring or a cantilevered stop.
[00134] In the engaged position, each of the contacts 112a to 112d is in electrical contact with a corresponding contact on the receptacle connector. The tongue 44 has a double, symmetrical, 180-degree design that allows the connector to be inserted into the connector's male socket with either surface 44a or 44b on top. In addition, the two audio contacts 112a and 112c are located on opposite sides of the connector in a diagonal arrangement. Thus, the microphone contact 112d is located directly opposite the audio contact 112a and the microphone contact 112b is located directly opposite the audio contact 112c. In this way, an audio contact is always on the right side of the connector and a microphone contact is always on the left side of the connector (as directed from the base of the connector to the distal end). A reading circuit on the receptacle connector or on the electronic device in which the receptacle connector is housed, can detect the direction in which the contacts 112a to 112d are defined and exchange the internal connections for the contacts in the male socket of the connector as appropriate. described above.
[00135] As shown in Figures 14A to 14D, contacts 112a to 112d are external contacts and connector 110 does not include an exposed cavity in which particles and debris can accumulate. To improve robustness and reliability, connector 110 is completely sealed and does not include moving parts. In addition, connector 110 has a considerably reduced insertion depth and insertion width compared to commonly available TRS and TRRS connectors. In a particular mode, the tongue
Petition 870190096258, of 26/09/2019, p. 46/104
44/88 of connector 50 has a width, X, of about 2 mm; a thickness, Y, of about 1 mm; and an insertion depth, Z, of about 4 mm. In another embodiment, the tongue 52 of the connector 50 has a width, X, of 4.1 mm; a thickness, Y, of 1.5 mm; and an insertion depth, Z, of 5.75 mm.
[00136] Reference is now made to Figures 15A to 15E, which show perspective views of connector 110 at various stages of manufacture. As shown in Figure 15A, at connector 110 is a dielectric frame 120 that supports contacts 112a through 112d. The frame 120 can be made of any suitable dielectric material, such as polypropylene, and includes respective slots (not labeled) on the upper and lower surfaces of the frame through which each of the contacts 112a to 112d are threaded to better support the contacts. In other embodiments, the frame 120 can be made of a ceramic material and the contacts 112a through 112d can be printed directly on the frame.
[00137] Frame 120 also includes grooves 122 that partially surround an outer periphery at a distal end of the frame, as well as reliefs 124a, 124b that are positioned to align with chamfers 104a, 104b formed in the metallic earthing ring 102 Wires 126, one per contact, extending from a cable 43 are welded to connection pads 128a to 128d for each of the contacts 122a to 112d, as shown in Figure 15B. The metallic earthing ring 102, which in the embodiment shown in Figure 15C is a U-shaped frame cast in mold from stainless steel, is then slid along the distal end of the connector such that the cracks along a surface The interior of the metal ring extends in the grooves 122 and a part of the base 102b of the earthing ring covers the welded connection pads 128a to 128d electrically coupled to the contacts 112a to 112d.
Petition 870190096258, of 26/09/2019, p. 47/104
45/88 [00138] The connector is then overmolded (Figure 15D) with thermoplastic polymer 130 or similar material to provide strain relief and insulation 132, for example, POM, is injected around the contacts. Finally, an ABS or similar coating 134 is positioned on and fixed or attached to the base 102 (b) of the tongue 102, as shown in Figure 15E, using an appropriate adhesive or other technique to form the body 42 and the complete formation of the connector . [00139] In another embodiment, the conductive earthing ring 102 can be made of a high-strength steel alloy or similar material. The earthing ring can be formed in an extrusion process in which the high-strength conductive material is extruded through a mushroom-shaped mold to form a straight metal piece 135 provided with a mushroom-shaped cross section, as shown in Figure 16A. The rod section 136 of the earthing ring can be designed to join with the grooves 122 positioned along the outer periphery of the dielectric frame 120 when the earthing ring is attached to the frame 120. The extruded part 135 can, then, be cut to length and notched to form U-shaped chamfers 104a, 104b that align with the reliefs 124a, 124b in the frame 120 before being curved to form the U-shaped earthing ring 102, as shown in Figure 16B. The rod section 136 of the U-shaped earthing ring 102 can then be aligned with the grooves 122 of the dielectric frame so that the earthing ring can be slid across the end of the frame 120 and welded, glued or otherwise connected to the various components of the connector (the particular method of connection being selected based on the materials that are connected) as shown in Figure 16C, which for simplicity omits various characteristics of the connector, such as contacts 112a to 112d.
Petition 870190096258, of 26/09/2019, p. 48/104
46/88 [00140] Figure 17A is a simplified perspective view of an audio plug connector 140 according to another embodiment of the present invention. Connector 140 is similar to connector 110 except that it has been reinforced at the base of tongue 44 to harden the connector and increase its strength in a side loading condition. Specifically, the connector 140 has a thicker base part 102 (b) under the outer shell 134 that forms the body 42. A chamfered edge 142 extends between the thicker base part to a part of the tongue connector 44. For keep the insertion depth, Z, of the connector the same as that of connector 110, each of the contacts 112a to 112d has a reduced length in connector 140 in comparison to connector 110. Although none of the Figures in the present are not intended to represent the exact dimensions of the connectors, the reduced length can generally be seen when comparing Figure 17A to Figure 14A, which shows the connectors 110.
[00141] Figure 18 is a simplified cross-sectional view of connector 140 along lines A-A 'shown in Figure 17D. As is evident from the cross-sectional view, the earthing ring 102 forms a tip 143 of the connector as well as the beveled edge 142. The insulators 144 and 145, which can be a single part or separate parts and can be made of a thermoplastic or similar material, involve the base and the tip of the tongue part of the connector 140, respectively, for cosmetic purposes. The insulator 144 also extends in the connector body 140, under the earthing ring 102 to provide the thickest base part. In a particular embodiment, insulators 144, 145 are made of polyoxymethylene plastic (POM). A dielectric frame 148 runs through connector 140 to provide support for contacts 112a through 112d. Wires 146 are welded to each of the contacts 112a to

112d in a cavity 149 formed in a connection cushion coupled to the contacts that is surrounded by the overmoulding 147. In other embodiments, shown as separate examples in Figures 19A and 19B (showing an expanded view of the chamfer part 142 of the tongue 44 together with a part of the outer sheath 134), the insulator 144 interacts with the earthing ring to provide a more secure connection between the insulator 144 and the earthing ring.
[00142] Reference is now made to Figure 20A, which is a simplified perspective view of a four-contact plug connector 150 according to another embodiment of the invention. Connector 150 is generally similar to connector 110 shown in Figure 14a, except that body 42 and tongue 44 of connector 150 have features that are generally more rectangular than similar features on connector 110 and connector 150 includes pockets 152 formed in the sides of tongue 44 as a retention feature instead of semicircular chamfers. As shown in Figure 20A, the edges of body 42 of connector 150 are less rounded and more rectangular than those of body 42 of connector 110. Similarly, the edges of tongue 44 on connector 150 are also less rounded and more rectangular than than those on tongue 44 on connector 110 and the tongue on connector 150 is shorter and stockier than that of connector 110.
[00143] The indentations or pockets 152a, 152b on each side of the connector on the earthing ring 102 act as retaining features, and work similarly to the chamfers 104a, 104b on the connector 110. Pockets 152a, 152b are adapted to engage operatively with a retaining mechanism when the connector is joined with a connector from the corresponding receptacle. The retention mechanism fits into pockets 152a, 152b and provides a
Petition 870190096258, of 26/09/2019, p. 50/104
48/88 retention power that secures connector 100 to the compatible receptacle connector. In addition to their retention feature, pockets 152a, 152b are part of the metallic earthing ring 102 and serve as earthing contacts, like contacts 47a and 47b described with reference to Figures 3A and 3B.
[00144] Now, reference is made to Figure 20B, which is an exploded view of connector 150, together with Figure 21, which is a flow chart that illustrates the steps associated with the manufacture of connector 150 according to an embodiment of the invention, and Figures 22A to 22G, which depict connector 150 at various stages of manufacture set out in Figure 19. The manufacture of connector 150 can begin with the construction of a flexible circuit 160 provided with flexible contacts 162a and 162b formed on an upper surface and a similar pair of flexible contacts (not shown in the Figures) formed on a lower surface, as shown in Figure 22A (Figure 21, step 170). The flexible contact 162a is electrically coupled to a welding seat 164a where a signal wire can be welded to the contact by a dash (not shown) in the flexible circuit. Similarly, flexible contact 162b is electrically coupled to a welding seat 164b by a trace on flexible circuit 160.
[00145] In one embodiment, flexible circuit 160 is made from two substantially identical flexible circuits 160a, 160b adhered together. For example, a first flexible circuit 160a with flexible contacts 162a and 162b formed on its upper surface and no contact formed on its opposite surface is adhered to a second flexible circuit 160b with two flexible contacts (not shown, but similar to contacts 162a and 162b ) formed on its upper surface and no contact formed on its opposite surface. The two surfaces without the contacts are then joined together to form an assembled flexible circuit 160 that has flexible contacts
Petition 870190096258, of 26/09/2019, p. 51/104
49/88
162a, 162b on a first surface and two equivalent contacts 162c, 162d on their opposite surface.
[00146] Contact disks 166a and 166b can then be attached to the flexible circuit in contact areas 162a, 162b, respectively, while contact disks 166c and 166d can be attached to contact areas on the other side of the flexible circuit. 160 (Figure 21, step 172 and Figure 22B). Disks 166a to 166d can be made from a variety of conductive materials and, in one embodiment, are nickel-plated brass. Disks 166a to 166d can be cut to size in a wedge or similar process from a foil and can be attached to flexible circuit 160 using surface support technology. Then, flexible circuit 160 can be inserted into earthing ring 102 (Figure 21, step 174 and Figure 22C) and a thermoplastic or similar dielectric overmold 163 can be formed around the contacts to provide substantially flat top and bottom surfaces and smooth from the tongue part 44 of the connector and provide a finished appearance (Figure 21, step 176 and Figure 22D). In one embodiment, the dielectric mold 163 is formed with an injection molding process that uses polyoxymethylene (POM).
[00147] A cable bundle 43 that has four individual insulated signal wires 161, one for each of the connector contacts 150, can then be attached to the earthing ring / flexible circuit assembly, as shown in Figure 22E when welding each of the wires 161 to their respective welding seat, for example, welding seats 164a to 164d (Figure 21, step 178). At this stage of manufacture, the end of a wrapper 157 of the cable bundle 43 is spaced from the flexible circuit 160 in an opposite relationship. An internal dielectric casing 165 is then formed around most of the assembly using a
Petition 870190096258, of 26/09/2019, p. 52/104
50/88 injection molding or similar process (Figure 21, step 180 and Figure 22F). The inner casing 165 includes a generally circular end part 167 that covers two centimeters or more of cable bundle 43 and a connector part 169 which, combined with the earthing ring 102, forms a part of the substantially monolithic base 159 of the connector 150. The inner shell 165 provides the structure and strain relief for connector 150 and can be made of a dielectric material such as an elastomer or a polypropylene material.
[00148] The construction of the connector 150 can then be completed by sliding an outer sheath 134 around the part of the monolithic base 159 that covers a part of the end base 102b of the earthing ring 102 and the inner housing 165 ( Figure 20, step 182 and Figure 219G). The outer sheath 134 can be adhered to the earthing ring and the inner shell using any suitable adhesive suitable for the particular materials that are bonded.
[00149] Figure 23A is a simplified perspective view of a plug connector 190 according to another embodiment of the present invention. Connector 190 includes many similar features in design and function as those of connector 150 discussed above. For example, connector 190 includes a tongue 44 that has four contacts 112a through 112d formed on its outer surface and arranged on opposite sides of the connector. The tongue 44 includes a grounding ring 102 that surrounds the contacts 112a to 112d and includes indentations or pockets 152a, 152b on each side of the connector tongue which are adapted to operatively engage with a retention mechanism when the connector is joined with a corresponding receptacle connector. Connector 190 differs from connector 150 in that it includes a beveled edge 192 between the tongue and the body that strengthens the connector under similar side loading energies
Petition 870190096258, of 26/09/2019, p. 53/104
51/88 to the beveled edge 142 of connector 140.
[00150] Now, reference is made to Figures 23B, which is an exploded view of connector 190, together with Figure 24, which is a flow chart illustrating the steps associated with the manufacture of connector 190 according to an embodiment of the invention and Figures 25A to 25H, which depict connector 190 in various stages of manufacture set out in Figure 24. The manufacture of connector 190 can begin with the formation of a contact frame 194 that carries four contact strips 196a through 196d, one for each of the contacts 112a to 112d. The contact frame 194 can be made of a dielectric material and, in a particular embodiment, is formed of a liquid crystal polymer that uses an injection molding process. The contact strips 196a to 196d can be coined from a sheet of metal, such as phosphorous bronze and threaded into the grooves 198a to 198d formed in the contact frame 194, as shown in Figure 25A (Figure 24, step 210).
[00151] Contact disks 204a and 204b can be attached to one end of contact strips 196a and 196b, respectively, while contact disks 204c and 204d can be attached to the corresponding ends of contact strips 196c and 196d (Figure 24 , step 212 and Figure 25B). Disks 204a through 204b can be made from a variety of conductive materials and formed in a variety of different ways. In a particular embodiment, discs 204a to 204d are coined from a sheet of nickel-plated brass and laser welded to their respective contact strips. Then, the contact frame 194 can be inserted into the earthing ring 102 (Figure 24, step 214 and Figure 25C) and a similar thermoplastic or dielectric mold 200 can form around the contacts to provide the upper and lower surfaces substantially flat and smooth from the tongue part of the connector and provide
Petition 870190096258, of 26/09/2019, p. 54/104
52/88 a finished appearance (Figure 24, step 216 and Figure 25D). In one embodiment, the dielectric mold 200 is formed from polyoxymethylene (POM) in an injection molding process.
[00152] Next, a cable bundle 43 that has four individual insulated signal wires 161, one for each of the connector contacts 190, is attached to the earthing ring / contact frame assembly, as shown in Figure 25E when welding each wire 161 to its respective contact strip (Figure 24, step 218). An internal dielectric shell 202 is then formed around most of the assembly using an injection molding process or similar process (Figure 24, step 220 and Figure 25F). Inner housing 202 includes a generally rounded or oval end part 167 that covers several centimeters or more of cable bundle 161 and a connector part 169 which, combined with earthing ring 102, forms a substantially monolithic base part 159 of connector 190. Inner housing 202 helps provide strain relief for connector 190 and can be made of a dielectric material, such as an elastomer or a polypropylene material. The construction of the connector 190 can then be completed by sliding an outer sheath 134 around a portion of the end base 102b of the earthing ring 102 and the inner housing 202 (Figure 24, step 222 and Figure 25G). The outer sheath 134 can be adhered to the earthing ring and the inner shell using any suitable adhesive suitable for the particular materials that are bonded.
[00153] Figure 26A is a simplified perspective view of a four-contact plug 230 according to yet another embodiment of the invention and Figure 26B is an exploded view of the connector plug 230. The connector 150 includes many features similar to connectors 150 and 190 discussed above with respect to
Petition 870190096258, of 26/09/2019, p. 55/104
53/88
Figures 20A and 23A, respectively. The connector 123 differs from these connectors in that the connector body 230 and the tongue part 44 of the connector that is designed to be inserted into a connector of the corresponding receptacle are combined as a single monolithic piece (only relatively small) with a shape of uniform cross section. In addition, part of the connector 230 is relatively flexible. Specifically, the connector 230 includes a rigid connector or part of the tip 232 and a part of the flexible base 234. In this particular embodiment, the rigid part 232 is approximately one third of the length of the connector while the flexible part 234 is approximately two thirds of the length . In other modalities, however, the relationship between the flexible and rigid stitch part can differ considerably.
[00154] Tip 232 of connector 230 includes a grounding ring 102 that surrounds contacts 112a through 112d on the tip and sides of the connector. The earthing ring 102 can be made of any suitable metal or other conductive material and, in one embodiment, is copper plated and nickel plated stainless steel. When fully inserted, the entire rigid part 232 is inside the receptacle connector along with a part 132 of flexible part 234 of connector 230. [00155] The flexible base part 234 of connector 230 can be made of a flexible dielectric material such as an elastomer or a polypropylene material that allows the connector to flex along the length of the connector to at least one point where the grounding ring begins in order to relieve tension during off-angle junction events in a manner similar to that described with respect to Figures 11A and 11B. In a specific example, the base part 234 is made of Arnitel EL250 available from DSM Engineering. Connector 230 also includes indentations or pockets 152a, 152b on each side of the connector on the earthing ring 102, as described in DisPetition 870190096258, of 26/09/2019, pg. 56/104
54/88 above.
[00156] Reference is now made to Figures 27A to 27G, which show connector 230 in various stages of manufacture. Contacts 112a through 112d are formed from a flexible circuit 235 to which contact disks 236a through 236d are attached. Discs 236a to 236d can be made from a variety of conductive materials and, in one embodiment, are brass. Discs 236a to 236d can be cut to size in a wedge or similar process from a foil and can be attached to flexible circuit 235 using surface support technology (SMT), as shown in Figure 27A. In a separate step, earthing ring 102 can be attached to connector body 230 by retaining clips 238 which can be made from the same stainless steel or other metal as the earthing ring and laser welded on locations 239 or otherwise connected to earthing ring 102, as shown in Figure 27B. The retaining clips 238 have an anchor at one end that extends beyond the earthing ring towards a connector base to secure the earthing ring to the connector body, as described more fully below.
[00157] Once the earthing ring / retaining clip and flexible circuit / contact disk assemblies are made, the flexible circuit assembly can be inserted into the earthing ring and adhered to it with an adhesive appropriate, as shown in Figure 27C. Then, a metal earthing bridge 240 and welding disc 242, each of which, for example, can be made of brass, are welded together and attached to the flexible circuit between the opposite ends of the retaining clips 238, as shown in Figure 17D. A cable 43 with signal wires 171 is then soldered to contacts 245, which are electrically connected to the contacts
Petition 870190096258, of 26/09/2019, p. 57/104
55/88
152a to 152d and carry the signals from the respective contacts (Figure 27E). As shown in Figure 27E, cable 43 has a generally flat part that is spaced from flexible circuit 235 in an opposite relationship. An internal dielectric sheath 246 is formed around most of the assembly using an injection molding process or similar process as shown in Figure 27F. The inner shell 246 extends from the substantially flat end of the cable 43 to the retaining clips 238 and provides structure resistance to the connector 230 covering the signal wires 171 and a portion of the flexible circuit 235. The inner shell 246 can be made of a flexible dielectric material such as an elastomer or polypropylene material as well as the outer shell 244 and, in a particular embodiment, is made of the same material as the outer shell.
[00158] The construction of the connector 230 can then be completed by forming the outer shell 244 around a portion of the end of the cable 170, the inner shell 246 and the other components of the connector using an injection molding process or process similarly formed by the substantially rectangular connector plug 230. As shown in Figure 27G, the outer casing 244 fills the gap between the contact discs and covers the anchors 230 that fill the semicircular space between each end of the anchor, thereby completely securing the earthing ring 102 and the components connected to the earthing ring to the connector body.
[00159] Reference is now made to Figure 28A, which is a simplified perspective view of an embodiment of a receptacle connector 250 that can be used in conjunction with certain plug connectors according to the present invention. The male socket of connector 250 includes a housing 252 that defines an inner cavity 254 in which a plug connector, such as connector 40, can
Petition 870190096258, of 26/09/2019, p. 58/104
56/88 be inserted. One or more contacts extends in the cavity 254 from each of the upper and lower inner surfaces of the cavity, the amount of which depends on the type of connector of the receptacle of the plug connector 250 with which it is intended to be used. For example, the receptacle connector 250 can be designed to join with a four-contact plug connector like connector 110 shown in Figures 14A through 14D and then include four contacts in cavity 254 - two on each of the interior surfaces larger opposites of cavity 254 and can be designed to join with a four-contact plug connector like connector 110 shown in Figures 14A through 14D. In other embodiments, the male socket of connector 250 can include any number of contacts, from pairs of one to twenty or more arranged on opposite surfaces of cavity 254 in a variety of different patterns that are compatible with the contact locations of a connector of plug in particular. As an example, the receptacle connector 250 may include contacts on both the upper and lower interior surfaces of cavity 254 that are positioned to electrically couple with the contacts arranged in a plug connector according to any of the contact patterns shown in Figures 5A at 5H, as well as other contact patterns.
[00160] As seen in Figure 28B, which is a front view of the male socket of connector 250, in a particular embodiment, the receptacle connector 250 includes four contacts 256a to 256d positioned to electrically couple to the appropriate contacts on the plug connector corresponding, for example, to contacts 112a to 112d on connector 110. Thus, contacts 256a to 256d are arranged in a symmetrical manner complementary to contacts 112a to 112d of the plug connector. Additionally, cavity 254 is shaped so that the plug connector can be inserted into the cavity at any
Petition 870190096258, of 26/09/2019, p. 59/104
57/88 of the two orientations: a first orientation in which the contacts of the plug connector in the region 46a (contacts 112a, 112b) are electrically coupled to the contacts of the receptacle connector that protrude from an upper interior surface of the cavity and a second orientation in which the contacts of the plug connector in region 46b (contacts 112c, 112d) are electrically coupled to the contacts of the receptacle connector that protrude from the upper interior surface. The circuitry in the receptacle connector male jack 250 detects the orientation of the plug connector and configures the software switches to properly pair the contacts to the plug connector contacts. For example, a first software switch can be used to switch contacts from the male jack of the connector to left and right audio depending on the insertion orientation, while a second software switch can be used to switch microphone and connection contacts. ground from male connector sockets to be compatible with connector 120 contacts.
[00161] To facilitate the insertion of double orientation, the upper and lower parts of cavity 254 (as defined by a plane 255 that horizontally divides the cavity as shown in Figure 28B) can be mirror images of each other. The left and right parts of cavity 254 (as defined by a similar plane vertically dividing the cavity in two) can also be mirror images of each other. In addition, the receptacle connector 250 does not include polarization switches that limit a junction event between the plug and receptacle connectors to a single orientation.
[00162] In some embodiments, the receptacle connector 250 is designed to be waterproof so as not to allow moisture to enter any electronic device in which the
Petition 870190096258, of 26/09/2019, p. 60/104
58/88 connector is housed. Also, a hole (not visible in the drawing) within the cavity 254 allows a spring-loaded retention mechanism 258 to project into the cavity. As shown in Figure 28C, which is a bottom plan view of the receptacle connector 250, the retention mechanism 258 includes a spring 260 positioned in a cut-out section 262 of the housing. Spring 260 is pre-loaded so that a tip 264 extends through an opening between cutout 262 and cavity 254. When plug connector 110 is inserted into cavity 254, spring 260 locks with any of the retention 104a or 104b of the connector plug depending on its insertion orientation. In some embodiments, spring 260 can be made of metal and also act as a grounding contact for receptacle connector 250.
[00163] As discussed earlier, the retention features 104a, 104b can be located near the distal end of the connector 110. The inventors have determined that positioning the retention features near the end of the plug connector (and thus positioning the corresponding retention near the back of cavity 254) helps to better hold the plug connector laterally when it is in a position engaged with receptacle 250 connector. In addition, the shape of the retention features on the plug connector may be compatible with the shape of the retention mechanism 258 to provide a comfortable snapping sensation when the retention mechanism engages the retention feature. For example, the rounded bulbous shape of the retaining features 104a, 104b of the connector 110 may be compatible with the rounded shape of the tip 264 of the mold 260 to provide a secure engagement between the structures. Figure 29 shows the plug connector 110 inserted in the male socket of the connector 250 in which one of the retaining features 104a, 104b is engaged with the spring 260.
Petition 870190096258, of 26/09/2019, p. 61/104
59/88 [00164] In Figures 28A to 28C, the suspension of contacts 256a to 256d of the receptacle connector 250 is placed at the ends of the contacts, as illustrated schematically in Figure 30A, which shows the contacts 256a, 256b of the receptacle connector 250 and its associated contact suspension 268 with respect to a plug connector 110 that has contacts 112a, 112b operably coupled to the male receptacle socket. In other embodiments, the contact suspension can be placed on the contact sides of the receptacle connector as shown in Figure 30B or above and below the contacts as shown in Figure 30C, which is a simplified side view of the plug connector 110 joined with the contacts on a receptacle connector (where, for ease of illustration, only the contacts on the receptacle connector are shown in the schematic representation).
[00165] Figure 31A is a front view of the receptacle connector 270 according to another embodiment of the invention. The receptacle connector 270 is similar to the receptacle connector 250 except, among other differences, in the shape of cavity 254, which is generally more rectangular than that of connector 250, and that connector 270 includes the first and second retention mechanisms 272a and 272b protruding into cavity 252 from opposite side surfaces of the cavity instead of a single retention mechanism. Each of the retention mechanisms 272a, 272b can include, for example, a spring that is preloaded so that one end of the retention mechanism extends through an opening on each side of the cavity 254. When a plug connector is inserted in cavity 254, the retention mechanism 272a, 272b engages with retention features, such as chamfers 104a, 104b or pockets 152a, 152b of one of the plug connectors discussed above. The retention mechanisms 272a, 272b can be located directly opposite Petition 870190096258, of 26/09/2019, p. 62/104
60/88 to each other in cavity 254 and can be designed to transmit a holding energy to the plug connector that is approximately equal on each side. Similar to the retention mechanism 258, the shape of the retention mechanism 272a, 272b can be compatible with that of the retention features of the plug connector to provide a comfortable popping sensation when the retention mechanisms and features engage with each other.
[00166] Figure 31B is a top plan view of the male socket of connector 270. As shown in Figure 31B, each of the receptacle contacts 256a to 256d includes a contact tip, 274a to 274d, respectively, that can be connected to a wire that electrically connects the contact to the circuitry associated with the electrical device in which the receptacle connector 270 is housed. For example, the male socket of connector 270 may be part of a portable media device and the electronic circuitry associated with the media device is electrically connected to the connector of receptacle 270 through the contact tips 274a through 274d.
[00167] As described above, several embodiments of the invention belong to a connector system that has 180 degree symmetry. Thus, cavity 254 can be symmetrical with respect to both the vertical and horizontal bifurcation plan, as discussed above. In addition, contacts 256a and 256b can be directly opposite contacts 256c and 256d so that a plug connector, such as connector 230, can be inserted into male socket 270 in either direction. In a first orientation, the plug connector contacts 112a, 112b are respectively coupled to the receptacle contacts 256a, 256b and the contacts 112c, 112d are respectively coupled to the receptacle contacts 256c, 256d. In a second orientation opposite the first orientation, the plug contacts 112a, 112b are coupled to the receptacle contacts 256d,
Petition 870190096258, of 26/09/2019, p. 63/104
61/88
256c, while the plug contacts 112c, 112d are coupled to the receptacle contacts 256b, 256a.
[00168] Although many of the modalities of the invention set out above have been depicted in the figures included as four-contact connectors, the modalities of the invention are not limited to any particular number of contacts. To further emphasize this, reference is now made to Figures 33A to 33D, which depict various views of a twelve-contact plug connector 300 in accordance with an embodiment of the present invention. Specifically, Figure 33A is a simplified perspective view of the plug connector 300 while Figures 33B to 33D are simplified bottom, front and side plan views, respectively. Connector 300 includes many of the same features as connector 150, except that it has six contacts 302 (1) and 302 (6) positioned in contact region 46a and six additional contacts 302 (7) and 302 (12) positioned in region 46b on the opposite surface of the tongue 44. The contacts can be made of copper, nickel, brass, a metal alloy or any other suitable conductive material. The spacing is consistent between each of the contacts on the front and rear sides and between the contacts and the edges of the connector providing 180 degree symmetry so that the plug connector 300 can be inserted into a connector on the corresponding receptacle in either of the two orientations as per discussed above.
[00169] A significant part of the tongue 44, including its shape, is defined by the earthing ring 102 that extends from a distal end of the connector towards the external shield and partially surrounds the contacts 302 (1) -302 (12 ) along an outer periphery of the tongue 44. The earthing ring 102 can be made of any suitable metal or other conductive material and, in one embodiment, is copper-plated and nickel-plated stainless steel. Two indentations or
Petition 870190096258, of 26/09/2019, p. 64/104
62/88 pockets 152a and 152b are formed in earthing ring 102 and located on opposite sides 56c and 56d of the tongue near its distal end as with connector 150. In one particular embodiment, tongue 44 of connector 300 has a width, X, of 4.0 mm; a thickness, Y, of 1.5 mm; and an insertion depth, Z, of 5.0 mm. It is understood that the dimensions of the connector 50, as well as the number of contacts, can vary in different modalities.
[00170] When connector 300 is properly engaged with a receptacle connector, each of the contacts 302 (1) -302 (12) is in electrical contact with a corresponding contact on the corresponding receptacle connector. Latch 52 has a double, symmetrical, 180-degree design that allows the connector to be inserted into a male socket on the connector both in a first orientation where the surface 44a faces upwards and in a second orientation where the surface 44b is facing up. In the first orientation, the plug connector contacts 302 (1) 302 (6) mate with the receptacle contacts 366 (1) -366 (6), respectively, and the contacts 302 (7) - 302 (12) mate to receptacle contacts 366 (7) -366 (12), respectively. In the second orientation opposite the first orientation, the plug contacts 302 (1) - 302 (6) mate with the receptacle contacts 366 (7) -366 (12) and the plug contacts 302 (7) - 302 (12) connect to receptacle contacts 366 (1) 366 (6).
[00171] To facilitate the orientation-independent feature of connector 300, contacts 302 (1) - 302 (12) are arranged such that the contacts proposed in a similar manner are located on opposite sides of the connector in a diagonal arrangement. As an example, reference is made to Figure 34A, which is a diagram that depicts the pin locations of connector 300 according to a specific modality.
Petition 870190096258, of 26/09/2019, p. 65/104
63/88 specific to the invention which has two contacts designated for power, two contacts designated for analog audio signals and eight contacts designated for differential data signals which include two USB data contacts, and six display port contacts.
[00172] As shown in Figure 34A, when a midpoint line 305 that divides the tongue of connector 44 into equal top and bottom halves and a midpoint line 306 that divides the tongue of connector 44 into left and right halves equal are considered, the contacts associated with connector 50 can be divided into four quadrants labeled clockwise from the left part of the top of the connector as quadrants I, II, III and IV, respectively. Quadrants I and III are located in a diagonal arrangement as are quadrants II and IV. The individual contacts in the diagonal quadrants can be arranged, based on their function, in a mirrored relationship. For example, the two contacts in quadrants I and III closest to the midpoint line 61, contacts 302 (3) and 302 (9), are each dedicated to energy. Similarly, the two outermost contacts in these quadrants are dedicated to a pair of differential data signals. In quadrants II and IV, the innermost contact, contacts 302 (4) and 302 (10) are each dedicated to analog audio signals while the outermost contacts in each quadrant are dedicated to a pair of audio signals. differential data.
[00173] As evident from a comparison of Figures 34A and 34B, which depict the pinout of connector 300 in two different orientations (in Figure 34A the surface 44a is facing upwards, while in Figure 34B the surface 44b is facing upwards), regardless of which of the two possible orientations that the connector 300 is inserted into its receptacle connector, the order of contact on the top side of the connector, from left to right, is always con
Petition 870190096258, of 26/09/2019, p. 66/104
64/88 form follows: the first two contacts are assigned to a pair of differential data signals, the third contact is assigned to an energy contact, the fourth contact is assigned to an audio contact and the fifth and sixth contacts are assigned to another pair of differential data signals. Similarly, the order of the contact on the bottom side of the connector, from left to right, is always as follows: the first two contacts are assigned to a pair of differential data signals, the third contact is assigned to a contact of audio, the fourth contact is assigned to an energy contact and the fifth and sixth contacts are assigned to another pair of differential data signals.
[00174] Now, reference is made to Figures 35 to 38. Figure 35 is an exploded view of connector 310 for a sync and charging cable that has the same form factor as connector 300 (and will then be operatively engaged with the same set of receptacle connectors as plug connector 300) including the same number of contacts. As a synchronization and charging cable, however, the contact locations dedicated to the audio contacts and the display port contacts are not required and are therefore not operational in this particular mode. Figure 37 is a flowchart that illustrates the steps associated with the manufacture of connector 310 according to an embodiment of the invention and Figure 38A to 38P depicts connector 310 at various stages of manufacture set out in Figure 37.
[00175] The manufacture of connector 310 can begin with the construction of printed circuit boards 312a and 312b (Figure 37, step 330) each of which includes six contact areas that together correspond to contacts 302 (1) - 302 (12). Figures 36A and 36B show more clearly a top plan view and side plan view, respectively, of PCB 312a. The contact discs are attached to the
Petition 870190096258, of 26/09/2019, p. 67/104
65/88 contact of PCB 312a to form contacts 302 (1) -302 (6). Contact discs can be made from a variety of conductive materials and, in one embodiment, are nickel-plated brass. The discs can be cut to size in a wedge or similar process from a sheet of metal and can be attached to the PCB 312a using surface support technology. As shown in Figure 36A, PCB 312a includes 315 wire welding islands that are electrically coupled to the corresponding contact areas. As noted above, because connector 310 is a sync and charging cable, connector 310 does not include electrical connections for audio contacts 302 (4) and 302 (10), nor does it include electrical connections for audio contacts. display port 302 (1) -302 (2), 302 (7) -302 (8) and 302 (11) -302 (12). Instead, the contacts formed at these locations are not coupled to the welding islands on the PCBs and are therefore not functional. This is shown in Figure 36A which shows the USB contacts 302 (5) -302 (6) and the power contacts 302 (3) coupled to the corresponding welding islands by means of electrical lines while the contacts 302 (1), 302 (2) and 302 (4) are not connected to the electrical tracks and are not connected to any of the welding islands 315. In other embodiments, all contacts 302 (1) -302 (12) can be operatively coupled to the welding islands on PCBs or different subsets of contacts can be coupled depending on the purpose of the connector.
[00176] After each of the PCBs 312a, 312b is constructed and the contacts are secured, the PCBs are inserted through the front side of the earthing ring 102 through top and bottom openings in the earthing ring surrounding the contacts as shown in Figure 38A to 38F. Then, the earthing plate 314 is sandwiched between the two PCBs 312a, 312b when inserting the earthing plate behind the earthing ring 102 (Figure 38G).
Petition 870190096258, of 26/09/2019, p. 68/104
66/88
The grounding plate 314 provides a thick layer of shield between the contacts 302 (1) -302 (6) formed on the PCB 312a and the contacts 302 (7) -302 (12) formed on the PCB 312b.
[00177] The assembled structure of the earthing ring / PCB / earthing plate (Figure 38H) is then placed in a molding tool and a similar thermoplastic or dielectric mold 316 can be formed around the contacts for provide the substantially flat and smooth top and bottom surfaces of the tongue portion of connector 310 and provide a finished appearance (Figure 37, step 334; Figure 38I). In one embodiment, the dielectric overmold 316 is formed with an injection molding process that uses polyoxymethylene (POM).
[00178] A bundle of cables 318 having individual signal wires 320, one for each of the functional contacts of connector 310, as well as one or more earthing wires to be coupled to earthing ring 102 can be prepared at this time or before step 330 (Figure 38J). The individual signal wires are cut and stripped, the cable bundle wrapper is stripped and the cable shields are folded back over the wrapper. Then, a cable wrinkle 322 that has a metal bottom shield is attached to the cable bundle (Figure 37, step 336; Figure 38K). The cable bundle can then be attached to the earthing / PCB ring assembly as shown in Figure 38L by soldering each signal wire to its respective welding island and soldering the earthing wires to the earthing (Figure 37, step 338). The solder joints and exposed wires can then be encapsulated with UV glue to further secure the connections.
[00179] At this manufacturing stage, the end of the 318 cable bundle is spaced from the PCB assembly in a
Petition 870190096258, of 26/09/2019, p. 69/104
67/88 opposition and positioned above the bottom metal shield 312 and between the two opposite ends of the earthing ring 102. A top metal shield 314 can be attached to the top of the earthing ring 102 (Figure 38M) and the top and bottom metal shields are laser-welded or secured in a similar manner to earthing ring 102 to form a wrap or box around the cable bundle (Figure 37, step 340). Then, a dielectric compensation piece 326 can be slid over the end of the tongue 102 and glued to the exposed front of the earthing ring 102 (Figure 37, step 342; Figure 38N). As shown in Figure 38N, the dielectric compensation includes two rails 326a, 326b that slide into the corresponding grooves in the earthing ring 102 and includes a front face 326c that is sized to have the same width and height as the base of the earthing ring. earthing 102. In one embodiment, compensation piece 326 can be made of ABS plastic or a similar dielectric material.
[00180] An internal dielectric stress relieving shell 328 is then formed around most of the assembly using an injection molding process or similar process (Figure 37, step 344 and Figure 38O). The strain relief housing 328 may include a generally circular end portion 328a that covers an inch or more of the cable bundle 318 and a block portion 328b that completes and fills in the gaps in the metal wrap formed by the earthing ring 102, the bottom shield 322 and the top shield 324 thereby forming a part of the substantially monolithic base 90 of the connector 310 that is efficiently sealed. The strain relief housing 328 provides the structure and strain relief for connector 310 and can be made of a dielectric material such as an elastomer or a polypropylene material.
Petition 870190096258, of 26/09/2019, p. 70/104
68/88 [00181] The construction of connector 310 can then be completed by sliding an outer sheath 134 around the part of the monolithic base that covers a part of the end of the earthing ring 102, of the compensation part 326 and strain relief housing 328 (Figure 37, step 346; Figure 38P). The outer sheath 134 may be formed of ABS or a similar dielectric material and adhered to the grounding ring and the inner shell using any suitable adhesive suitable for the particular materials that are bonding.
[00182] Figures 39A to 39D show the top, perspective, front and side views of a receptacle connector 360 according to an embodiment of the invention designed to have a reduced width in comparison to the depth. The receptacle connector 360 includes a housing 362 that defines a cavity 364 and houses twelve contacts 366 (1) -366 (12) in the cavity. In operation, a connector plug, such as plug connector 300, can be inserted into cavity 364 to electrically couple contacts 302 (1) -302 (12) to the respective contacts 366 (1) -366 (12). Positioned along the sides of the interior of the cavity 364 are two conductive spring-loaded retaining clips 368a, 368b that project into the cavity and function both to secure the plug connector in the cavity and to provide a ground connection for the connector.
[00183] The retention mechanisms 368a, 368b may include, for example, a metal spring that is preloaded so that one end of the retention mechanisms extends through an opening in each side wall of the cavity 364. When a plug is inserted into cavity 364, retaining clips 368a, 368b engage with pockets 152a, 152b, respectively, of the connector plug. The shape of the retention mechanism 368a, 368b is compatible with that of pockets 152a, 152b to provide a feeling of
Petition 870190096258, of 26/09/2019, p. 71/104
69/88 comfortable snap when the retaining clips engage with the pockets. In one embodiment, the depth and position of the pockets are positioned to provide the specific insertion and extraction energies, such that the holding energy required to insert the plug connector into the receptacle 360 connector is greater than the extraction energy required to remove the plug connector from the receptacle connector. Also, in one embodiment, the retaining clips 368a, 368b are located near the rear surface of the cavity 364. The inventors have determined that positioning the retaining clips near the rear of the cavity, which requires pockets 152a, 152b on the connector plug are positioned near its distal end, it helps to better secure the connector laterally when it is in a position engaged with the male connector 360 socket.
[00184] Each of the 366 (1) -366 (12) receptacle contacts electrically connects its respective plug contact to the circuitry associated with the electrical device in which the 360 receptacle connector is housed. For example, the receptacle 360 connector can be part of a portable media device and the set of electronic circuits associated with the media device is electrically connected to the male plug 360 when soldering the contacts 366 (1) 366 (12) extend outside housing 362 to a multilayered board, such as a printed circuit board (PCB) on the portable media device. In addition, each of the conductive retaining clips 368a, 368b can be electrically coupled to a grounding path associated with connector 360. As an example, in one embodiment, the pins at one rear end of the retaining clips 368a, 368b can be welded to the connection pads formed on the multilayer plate or PCB associated with the portable media device, which are coupled to the ground.
[00185] Figures 40A to 40D show the top views, in pers

70/88 perspective, front and side of a receptacle connector 370 according to another embodiment of the invention designed to have a reduced width compared to the width. Except that the dimensions of the housing 363, the components of the connector 370 are similar to those of the connector 360 and are therefore referred to with the same numerical references.
[00186] In one embodiment, each of the receptacle connectors 360 and 370 can be formed using the process depicted in Figure 41. For example, contacts 366 (1) -366 (12) can be formed of lead frames minted at from a suitable metal, such as nickel-plated brass (Figure 41A). The contacts can be arranged and spaced in a mold and inserted molded into the dielectric blocks 369 made of a thermoplastic or similar material to form two separate sets of contacts (Figure 41B). Each of the contact sets can then be attached to the interior top and bottom surfaces of housing 362 (Figure 41C) so that a front end of the contact extends into the cavity 364 formed by the housing and a rear end of the contact extends out of the rear of the housing so that it can be sealed to a connection pad (not shown) formed on a printed circuit board or electrically connected in a similar way to the desired circuitry associated with the electronic device in which the receptacle connector is lodged.
[00187] The retaining clips 368a, 368b can be formed in a similar way using a metal wedge process and mounted on the sides of the housing 362 (Figure 41D). The retaining clips 368a, 368b may include pins 367 extending past a rear end of housing 362 in order to electrically ground the retaining clips to the electrical device in which the receptacle connector 360 is housed, as discussed above.

Then, the partially assembled receptacle connector can be placed in a mold and liquid silicone rubber can be injected around the housing to form a shield 380 that seals the receptacle connector (Figure 41E). The metal top and bottom liners 382 and 384 can then be attached to the silicone rubber shroud 380 at the top and bottom of housing 362, respectively, and laser welded together to form an outer shell that provides additional shielding for the connector (Figure 41F). Finally, a 386 conductive EMI gasket can be attached to the front of the housing to further seal the connector when the receptacle connector and plug connector are joined (Figure 41G).
[00188] Figure 42 is a simplified perspective view of a plug of connector 390 according to another embodiment of the invention in which a grounding ring is not employed. Instead, connector 390 is made up of two printed circuit boards 392a, 392b sandwiched around a structural conductive member 264, such as a brass plate. A portion of tongue 395 extends out of body 42 and has the same form factor as tongue 44 of connector 300 shown in Figure 32 including the same twelve contacts (six on an upper surface of connector 390 and six on a lower surface ) spaced the same distance from the edges of the connector in the same spacing that allows plug connector 390 to be operatively coupled to the same receptacle connectors as plug connector 300.
[00189] Connector 390 does not include a grounding ring similar to earthing ring 102, however. Instead, the indentations 396a, 396b formed on the opposite sides of the conductive member 394 are generally compatible with the size and contour of the pockets 152a, 152b giving the part of the tongue of the connector 390 a shape of a loaf of bread when viewed from above or under. Indenta

72/88 Sections 266 provide the connector with the same comfortable snap / lock sensation achieved by connector 300 when it is inserted and removed from a receptacle connector. Also, when joined with a receptacle connector, conductive member 394 receives a ground connection through the retaining clips on the receptacle connector.
[00190] Another example of a data connector according to the present invention is illustrated in Figure 43, which is a perspective view of a connector 400 according to another embodiment of the invention. The connector 400 includes eight contacts arranged as four pairs of contacts 401, 402 on a first major surface of the tongue 44 and 403 and 404 (not shown in Figure 43) on the opposite major surface. In one embodiment, each of the contact pairs carries complementary or proposed signals in a similar way. For example, in a particular mode the pair of contacts
401 includes the first and second power signals, the contact pair
402 includes a first set of positive and negative differential data signals, pair 403 includes a second set of positive and negative differential data signals, and contact pair 404 includes a third set of positive and negative differential data signals (the contact pairs 403 and 404 are not shown in Figure 43, but are directly opposite the contact pairs 401 and 402). The data contacts can be used to carry any appropriate data signal, as well as audio signals, video signals and the like. From an outside view, unlike many contacts, connector 400 is similar to connector 300 and includes a grounding ring 102, an outer cap 216 and pockets 217 that are similar to the components of the same name in connector 300. Additionally, the earthing ring 102 includes a beveled edge 192 to increase the strength of the connector.
Petition 870190096258, of 26/09/2019, p. 75/104
73/88 [00191] Figure 44A is a cut-away view in simplified perspective of connector 400 in which the individual contacts 402a and 402b the pair of contacts 402 are completely visible without surrounding the molding or the earthing ring. Each of the contacts is attached to a printed circuit board 405 which has a ground plane 408 sandwiched in the top and bottom dielectric layers 406a and 406b. Contacts 401a, 401b and 402a, 402b are attached to conductive pads (not shown) formed in dielectric layer 406a while contacts 403a, 403b and 404a, 404b are attached to conductive pads formed in dielectric layer 406b. The ground plane 408 is then positioned between the sets of contact pairs (401 and 404) and (402 and 403) which reduces the signal interference that may otherwise occur between closely spaced contact pairs.
[00192] Figure 44B is a simplified cross-sectional view of connector 400 through the middle of the contact pairs. As shown in Figure 44B, the contact pairs 401-404 are divided into four quadrants by the ground plane 404 and a central rib 415a, which is part of the earthing ring 102. The rib 415a runs longitudinally through the tongue part of the connector 400 dividing the tongue into left and right halves with pairs of contacts 401 and 404 in one half and pairs of contacts 402 and 403 in the opposite half. Figure 44B also shows that dielectric overmoulding 418 (for example, a thermoplastic material such as POM) fills in the gaps between the individual contacts of each pair of contacts (for example, between contacts 401a and 401b), as well as between pairs contacts and earthing ring 102 and rib 415a.
[00193] Now, reference is made to Figure 45, which is a partial and simplified cut-away perspective view of a plug connector 400 and a male socket of the receptacle connector 420 according to an embodiment of the invention in which the connector of plug 400 is
Petition 870190096258, of 26/09/2019, p. 76/104
74/88 positioned near the male socket of connector 420 before a join event. The male socket of connector 420 includes an outer shell 422 that defines an inner cavity 424 into which the tongue portion of plug connector 400 can be inserted. The receptacle connector includes four pairs of contacts 426 to 429 that extend into cavity 424 and holders 425 that extend from opposite side walls of male socket 420 in cavity 424. When plug connector 400 is inserted into cavity 424, holders 425 interlock with pockets 152a, 152b to secure the plug connector in cavity 424 and the individual contacts in the contact pairs 401 to 404 of the plug connector are electrically coupled to the individual contacts of the contact pairs 426-429, respectively, of the connector the receptacle.
[00194] Each of the contacts in the contact pairs 426 to 429 can be inserted molded in a dielectric block 429 made of a thermoplastic or similar material with a front end of the contact extending in the cavity 424 and a rear end extending in the opposite direction towards a rear end of the receptacle connector. In Figure 45, only the individual contacts 402b and 404a, 404b of the receptacle connector 420 can be seen. The rear end of each contact is electrically coupled to a connection pad (not shown) formed on the printed circuit board (PCB) 426. The conductive traces (not shown) on the PCB 426 connect the contacts to the circuitry associated with the electronic device in which the receptacle connector 420 is housed. To reduce signal interference between contacts and improve earthing, the receptacle connector 430 includes earthing contacts and a ground plane 428 that generally surrounds the pairs of contacts and divides them into quadrants that correspond to the associated quadrants contacts 401 to 404. Specifically, a contact
Petition 870190096258, of 26/09/2019, p. 77/104
75/88 earthing contact can be located between each pair of contacts and a side wall of housing 422 while other earthing contacts can be located between contact pairs 403, 404 and 401, 402, respectively. Each of the earthing contacts is positioned to make contact with a different part of the earthing ring 102 when the connectors are joined. The ground plane 428 is formed on PCB 426 and sandwiched between an upper dielectric layer 426a and a lower dielectric layer 426b. Finally, a conductive gasket 430 provides sealing and environmental shielding when the male socket 420 and the plug connector 400 are joined.
[00195] Any of the connectors discussed herein can be modified to include one or more fiber optic cables that extend through the connector and can be operatively coupled to receive or transmit optical data signals between a connector's conjugated male socket. As an example, Figures 46A to 46D illustrate an example of a connector 440 that has five analogous contacts as well as a fiber optic cable 445 that runs through the center of the connector. Analog contacts include contacts 112a, 112c for left and right audio, a contact 112b for microphone, a contact 112d for power, and a contact 222e for grounding. The 230 fiber optic cable allows transmissions with a high data rate and can be used for USB 4.0 compatibility (eg 10GB / second data transfer). With power, audio and data connections, connector 440 can be used to charge a device while simultaneously providing data and audio functions.
[00196] As shown in Figure 46D, which is an expanded view of the distal end of the connector 440, the fiber optic cable 445 ends in a lens 446 positioned at the distal end of the connector and secured in place by the earthing ring 425. 446 lenses

76/88 can be made of chemically fortified aluminum silicate glass or a similar material that is highly resistant to scratches and is flush with the outer surface of the 425 earthing ring to prevent debris accumulation and light abstraction.
[00197] Some modalities of the invention belong to connectors specifically designed for specific functions, for example, as required by certain accessories or cable adapters, as described below with respect to Figures 47 to 59. In the described modalities and unless noted conversely, each of the connectors described with reference to Figures 47 to 59 includes a connector tongue that is similarly designed in the shape and dimensions of tongue 44 of plug connector 300 shown in Figure 32, including contact spacing and the side retention pockets, so that the various tabs of the connector are generally insertable and usable with the same receptacle connector as the plug connector 300. Also, each of the connectors described in Figures 47 to 59 includes a ring for connection to the ground that allows the connector to be connected to earth through grounded retaining clips into a connector on the corresponding receptacle, as described above.
[00198] As a first example of a specifically proposed connector, Figure 47 is a simplified perspective view of a plug connector 500 according to an embodiment of the invention specifically designed for headphones and other audio applications. The 500 connector includes four contacts, two contacts on an upper surface of a portion of the 502 connector tongue and two contacts on the lower surface of the 502 connector tongue. The four contacts provide left and right audio, as well as power for the microphone, and are sized and spaced such that they are compatible with the locations of contacts 302 (3) and 302 (4)

77/88 on one side and are compatible with the location, size and spacing of contacts 302 (9) and 302 (10) on the other side. Thus, as shown in Figure 49A, the two contacts on each side can be used to represent energy and audio and align (depending on the orientation of connector 500) either with the power contact or with the audio contact shown in Figure 34A or shown in Figure 34B. In one embodiment, the circuitry associated with an electronic device into which the connector 500 can be plugged allows the contacts to be used in a backward compatibility mode where the power contact is replaced by a contact from the Bias Microphone as shown in Figure 49B. Figure 48 is a simplified perspective view of a headset 510 that includes the connector 500 shown in Figure 47 according to an embodiment of the invention that includes left and right in-ear headphones 512, 514 connected to the connector 500 by a cable 516.
[00199] Figure 50 is a simplified perspective view of a connector plug 520 according to another embodiment of the invention that is specifically adapted for use in data synchronization and charging applications. For this purpose, connector 520 includes fully functional contacts at the two locations designated for the USB data that align with the contact locations 302 (5) and 302 (6) and the two locations designated for power that align with the contact locations 302 (3) and 302 (9) as shown in Figure 52, as well as the grounding contacts that connect to connector 520 through its grounding ring via the receptacle connector retaining clips , as described above. As configured, connector 520 allows USB 2.0 synchronization, as well as 5 volt, 2 amp charging. Figure 51 is a simplified perspective view of a USB 530 adapter cable that has a plug

The connector 540 includes the active circuitry (not shown) in a sheath 542 that allows the conversion of video signals from the display port to HDMI signals. The 540 connector includes the full complement of twelve functional contacts, as shown in Figures 34A and 34B. Figure 54 is a simplified perspective view of an audio / visual adapter cable 600 that has an HDMI 602 connector, a USB 604 connector and a digital audio connector 606 at one end connected by a cable 608 to connector 540 on another end according to an embodiment of the invention. The active circuitry in casing 542 of connector 540 separates the audio and digital data sent by the six data contacts from the display port of connector 540 by sending the audio signals to both the 606 digital audio connector and the HDMI connector. 602 while sending the video signals to the HDMI 602 connector. The USB data signals can pass through the USB contact pins of the 540 connector directly to the USB 604 connector.

Figure 56 is a simplified perspective view of an audio / visual adapter cable 620 that has a mini-display port connector 622 on one end connected by a cable 628 to a high speed data connector 626 on the other end according to another embodiment of the invention. The 626 connector has a pinout that includes two high speed differential data input contacts and two high speed differential data output contacts as shown in Figure 57 instead of display port contacts. High-speed data contacts allow data transfer rates of up to 10GB / second, thereby allowing data transfer of 5 GB / s using PCI-express 2.0 and 8 GB / s using the PCI-express 3.0 standard. The active circuitry embedded in the 626 connector sheath converts PCI-express signals as needed into other data formats, such as mini-display port signals.
[00202] Figure 58 is a simplified perspective view of a docking station 630 that includes a tongue of connector 635 according to an embodiment of the invention that has the same form factor and contact arrangement as tongue 44 in Figure 32. The tongue 635 extends upwards from a surface 632 on which a portable electronic device can be placed when docked at station 630 with the tongue 635 joined with a receptacle connector built into the portable media device. A second surface 634 can support a rear of the electronic device while docked.
[00203] The docking station 630 allows a portable media device, such as an iPod or MP3 player or an iPhone or other smartphone to be connected to a host computer via

Connector 635 supports the full complement of twelve contacts set out in Figures 34A and 34B and then allows line-out audio, Mikey bus control and a two-channel display port, as well as a USB 2.0 sync, 5 volt charging, 2 amp and a 3 volt accessory output signal. In another embodiment, the docking station 630 does not provide full audio / video support and instead provides loading and transferring data via USB, as well as audio output and inheritance / UART control (receiver / universal asynchronous transmitter). Figure 59 is a diagram showing the pin locations of the connector 635 tongue shown in Figure 58 according to this additional embodiment with reduced contact pins on the 635 tongue.
[00204] Although the discussion of the various connectors in particular for accessories, cable adapters or other devices set out above with respect to Figures 47 to 59 that specifically include connectors with twelve contacts that have a connector outline compatible with that of the plug connector 300 discussed with reference to Figures 32 to 34B, the embodiments of the invention are not so limited. In other embodiments, accessories, cable adapters and other similar or identical devices may include connectors provided with twelve contacts arranged in a different outline of the connector 300 or provided with contacts dedicated to the different signals or signals arranged in a different order. In addition, still other embodiments include accessories, cable adapters and other similar or identical devices that include connectors with fewer or more contacts than the 300 connector. A person skilled in the art will readily recognize these and other alternative embodiments of the present invention based on present revelation.

81/88 [00205] The modalities of the invention are suitable for multiple electronic devices, including any device that receives or transmits audio, video or data signals, among others. On some occasions, the modalities of the invention are particularly well suited for portable electronic media devices because of their potentially small form factor. As used in the present, an electronic media device includes any device with at least one electronic component that can be used for the present human-visible media. Such devices may include, for example, portable music players (for example, MP3 devices and Apple iPod devices), portable video players (for example, portable DVD players), cell phones (for example, smart phones such as Apple iPhone devices), video cameras, digital imaging cameras, projection systems (for example, holographic projection systems), game systems, PDAs, desktop computers, as well as tablet devices (for example, Apple iPad devices), laptop computers, or other mobile computers. Some of these devices can be configured to provide audio, video or other data or sensor output.

82/88 together with control circuits 730 can communicate with the other components of the electronic media device 700 (for example, via bus 740) to control the operation of the electronic media device 700. In some embodiments, set of electronic circuits control 730 can execute instructions stored in memory 745. The control circuitry 730 can also be operative to control the performance of the electronic media device 700. The control circuitry 730 can include, for example, a processor, a microcontroller and a bus (for example, to send instructions to the other components of the electronic media device 700). In some embodiments, the control circuitry 730 can also trigger the display and process inputs received from input component 720.
[00207] The 745 memory can include one or more different types of memory that can be used to perform the functions of the device.
