    PREVIOUS HISTORY
    This application claims the benefit of pending US Patent Application No. 12 / 931,820, filed with the United States Patent and Trademark Office on February 11, 2011, the specifications of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION FIELD OF THE INVENTION
    The disclosed invention, in general, relates to an electromagnetic relay assembly incorporating a rotating core coil assembly. More particularly, the disclosed invention relates to an electromagnetic relay assembly having a rotatable magnetically actuating coil assembly on a rotation axis extending orthogonally with respect to the coil driving axis. BRIEF DESCRIPTION OF THE STATE OF THE TECHNIQUE
    In general, the function of an electromagnetic relay is to use a small amount of energy in the electromagnet to move a rotor that is capable of switching a much larger amount of energy. As an example, whoever designs the relay may want the electromagnet to energize using 5 volts and 50 milliamps (250 milliwatts), while a rotor can support 120 volts at 2 amps (240 watts). Relays are very common in home appliances where there is an electronic control to turn on (or off) some application devices such as a motor or a light. Several exemplary state-of-the-art electromagnetic relay assemblies disclosed in United States patents are briefly described hereinafter.
    United States Patent No. 6,046,660 ('660 Patent), which is issued to Gruner, discloses a Latching Magnetic Relay assembly with a Linear Motor. The '660 Patent describes a magnetic retention relay capable of transferring currents in excess of 100 amps for use in regulating the transfer of electricity or in other applications requiring switching currents in excess of 100 amps. A relay motor assembly has an elongated coil spool with a cavity extending axially in it. An excitation coil is wound around the spool. A ferromagnetic frame, generally U-shaped, has a core section arranged in and extending through the cavity extending axially in the elongated coil spool.
    Two contact sections generally extend perpendicular to the core section and rise above the motor assembly. An actuator assembly is magnetically coupled to the relay motor assembly. The actuator assembly is comprised of an actuator frame operatively coupled to a first and second ferromagnetic pole parts, in general, in a U shape, and a permanent magnet. A contact bridge made of a copper sheet of conductive material is operatively coupled to the actuator assembly.
    United States Patent No. 6,246,306 ('306 Patent), which is issued to Gruner, discloses an Electromagnetic Relay with Pressure Spring. The '306 Patent teaches an electromagnetic relay having an engine mount with a spool attached to a housing. A core is connected adjacent to the spool except for the core end, which extends from the spool. A rotor end magnetically engages the core end when the coil is energized. An actuator engages the rotor and a plurality of center contact spring assemblies. The center spring assembly is comprised of a center contact spring which is not pre-tilted and is ultrasonically welded on a center contact terminal.
    A normally open spring is positioned relatively parallel to a center contact spring. The normally open spring is ultrasonically welded over a normally open terminal to form a normally open external contact spring assembly. A normally closed external contact spring is positioned vertically with respect to the center contact spring so that the normally closed external contact spring assembly is in contact with the center contact spring assembly, when the center contact spring is not being actuated by the actuator. The normally closed spring is ultonically welded on a normally closed terminal to form a normally closed assembly. A pressure spring pressurizes the contact spring from the center above the actuator when the actuator is not in use.
    United States Patent No. 6,252,478 ('478 Patent), which is issued to Gruner, discloses an Electromagnetic Relay. The '478 Patent describes an electromagnetic relay having a motor assembly with a spool attached to a frame. A core is disposed within the spool except for a core end that extends from the spool. A rotor end magnetically engages the core end when the coil is energized. An actuator engages the rotor and a plurality of movable blade assemblies. The movable blade assembly is comprised of an ultrasonically welded movable blade over a center contact terminal.
    A normally open blade is positioned relatively parallel to a movable blade. The normally open blade is ultrasonically welded over a normally open terminal to form a normally open contact assembly. A normally open contact assembly comprised of a third contact rivet and a normally closed terminal. A normally closed contact assembly is positioned vertically with respect to the movable blade so that the normally closed contact assembly is in contact with the movable blade assembly when the movable blade is not being actuated by the actuator.
    United States Patent No. 6,320,485 ('485 Patent), which is issued to Gruner, discloses an Electromagnetic Relay Assembly with a Linear Motor. The '485 Patent describes an electromagnetic relay capable of transferring currents in excess of 100 amps for use in regulating the transfer of electricity or in other applications requiring switching currents in excess of 100 amps. A relay motor assembly has an elongated coil spool with a cavity extending axially in it. An excitation coil is wound around the spool. A ferromagnetic frame, generally U-shaped, has a core section arranged in and extending through the cavity that extends axially in the elongated coil spool.
    Two contact sections generally extend perpendicular to the core section and rise above the motor assembly. An actuator assembly is magnetically coupled to the relay motor assembly. The actuator assembly is comprised of an actuator frame operatively coupled to a first and second piece of ferromagnetic pole, in general, in a U shape, and a permanent magnet. A contact bridge made of a copper sheet of conductive material is operatively coupled to the actuator assembly.
    United States Patent No. 6,563,409 ('409 Patent), which is issued to Gruner, discloses a Latching Magnetic Relay Assembly. The '409 Patent describes a magnetic retention relay assembly comprising a relay motor with a first coil spool having a first excitation coil wound around it and a second coil spool having a second excitation coil wound around it, both said first excitation coil and said second excitation coil being identical, said first excitation coil being electrically isolated from the second excitation coil; an actuator assembly magnetically coupled to both said relay motor, said actuator assembly having a first end and a second end; and one or two groups of contact bridge assemblies, each of said group of contact bridge assemblies comprising a contact bridge and a spring.

    Schmelz, Duchemin, and certain of Gruner's disclosures were particularly relevant to the subject matter as described in Patent Nos. US 7,659,800 (a '800 Patent) and US 7,710,224 (a' 224 Patent), which is issued to Gruner et al. The '800 and' 224 Patents describe electromagnetic relays essentially comprising a coil assembly, a rotor or bridge assembly, and a switch assembly. The coil assembly comprises a coil and a core and a C-shaped core. The coil is wound around a coil axis extending through the core. The core comprises core terminations parallel to the coil axis. The bridge assembly comprises an H-shaped bridge and an actuator.
    The bridge comprises medial, lateral and transversal field paths. The actuator extends laterally from the lateral field path. The core terminations are coplanar with the axis of rotation and received between the medial and lateral field pathways. The actuator is cooperable with the switch assembly. The coil creates a magnetic field that can be directed through the bridge assembly through the core endings to transmit bridge rotation over the axis of rotation. Bridge rotation moves the actuator to open and close the switch assembly.
    Notably, Kirsch Patent No. 5,568,108; Reger et al. Patent No. 6,046,661; Nakagawa et al. Patent No. 6,426,689; Schmelz Patent Nos. 6,661,319 and 6,788,176 and Gruner et al. '800 and 224 patents teach or describe rotor assemblies having a pivotable H-shaped portion on a pivot axis of rotation, the H-shaped portion of which comprises or is otherwise attached to an elongated actuator arm extending from the H-shaped portion.
    It is noted that an inherent problem with conventional electromagnetic relays incorporating a coil assembly and a rotor of the previous type (s) is that they are quite susceptible to magnetic tampering. This is primarily because the rotation rotor houses a permanent magnet. These permanent magnets react to the magnetic field generated by the coil and are either repelled or attracted, thus creating a mechanical movement to open and / or close the contacts.
    This leaves the relay (s) vulnerable to tampering by using a very large magnet (ie, positioning a large conflicting magnetic field) external to the relay. As long as permanent magnets are housed in a rotating plastic housing, this means that t will only maintain its state as long as no other magnetic or mechanical forces are exerted on the relay which is greater than the magnetic holding force of the permanent magnets.
    It is noted that certain international standards require the relay to maintain its state either in the open or closed position when a magnetic field measuring at least 5000 Gauss is brought within 40 millimeters of the relay. During this test, many relays cannot operate due to the conflicting 5000 Gauss magnetic field. This type of tampering is common in developing countries or in low-income areas to bring the electricity meter back after the utility company has turned it off remotely.
    The state of the art, therefore, perceives a need for an electromagnetic relay that is resistant to magnetic tampering by means of which permanent magnets are fixed or anchored and the coil assembly itself rotates with minimized displacements in order to intensify the operating magnetic field. another way inherent in magnets of the same size. SUMMARY OF THE INVENTION
    It is, therefore, in the objective of the present invention to provide a so-called bistable electromagnetic relay assembly in which the permanent magnets are fixed inside the plastics and the coil itself rotates, unlike conventional relays incorporating fixed coils and associated permanent magnets cooperatively with rotating rotors. To achieve this and other readily apparent objectives, the present invention essentially provides an electromagnetic relay assembly to allow current to pass through switch terminals, the relay of which comprises a rotating electromagnetic coil assembly, first and second pairs of opposite permanent magnets, and a switch assembly.
    The rotating coil assembly comprises a current conductor coil, an axially extending coil core, and a rotating coil housing. The coil is wound around the core, the core of which is collinear or parallel to the axis of the coil. The coil comprises electromagnet drive terminations, the core comprises opposite core terminations, and the coil housing has a rotating housing axis orthogonal to the coil axis.
    The first and second pairs of opposing permanent magnets are respectively and fixedly positioned adjacent to the core terminations so that the core terminations are respectively displaceable intermediate to the magnet pairs. The switch assembly comprises first and second connecting arms, and first and second spring arms. The connecting arms interconnect the core terminations and spring arms. The spring arms each comprise opposite pairs of contacts and a switch terminal.
    The coil operates to create a magnetic field that can be directed through the core to transmit rotation of the coil housing on the axis of the rotation housing by means of attraction to the positioned / anchored permanent magnets. The core terminations displace connecting arms, and the connecting arms actuate the intermediate spring arms to an open switch mounting position and a closed switch mounting position, the latter of which allows current to pass through the switch assembly via contacts and switch terminals.
    Certain peripheral features of the essential electromagnetic relay assembly include, for example, certain spring means for dampening intermediate contact vibration to the contacts when switching from the open to the closed position. In this regard, it is contemplated that the spring arms each can preferably comprise first and second spaced spring sections cooperative with the connecting arms and laterally spaced from the contacts in order to maximize the damping effect when switching from the positions of open to closed switch assembly.
    In the latter, it is noted that the contact jump is a major problem for all electro-mechanical switching gears when closing on an electrical charge. To overcome this, many have added additional leaf or helical springs to cushion the bounce of the contacts. The present invention takes advantage of a simple stamping process that allows the incorporation of an integrated bounce reduction spring on both sides of the contact site instead of just one.
    While the loose end of a spring is the most likely place to open when operating the relay, it can still occur that the contacts open even if the loose end of the spring is set to the closed position. To overcome this, an additional stamping procedure has been incorporated into the present invention in order to apply contact pressure on both the left and right side of the contact, ensuring equal contact pressure and making sure that the contacts are closed when the relay is operated.
    Other objectives of the present invention, as well as particular features, elements, and advantages thereof, will be elucidated or will become apparent from the following description and the accompanying illustrated figures. BRIEF DESCRIPTION OF THE FIGURES

    Referring now to the figures, the preferred embodiment of the present invention refers to the so-called bistable electromagnetic relay assembly (with X drive motor) 10 as, in general, illustrated and referenced in Figures Nos. 1, 2, 4 and 5. Assembly 10 is believed to teach the basic structural concepts supporting the present invention, whose basic structural concepts can be applied both to single pole assemblies as, in general, displayed and supported by assembly 10, as well as multiple pole assemblies. In this last respect, an assembly of four exemplary poles 20 is generally illustrated and referenced in Figure Nos. 16 - 19.
    The electromagnetic relay assembly 10 functions essentially to selectively allow current to pass through the switch terminals 11. The electromagnetic relay assembly 10 preferably comprises an electromagnetic coil assembly 12, first and second pairs of opposing permanent magnets 13, and an assembly of switch comprising several components, including first and second connecting arms 14 (comprising one or more L-shaped portions), and first and second spring arms 15, whose arms 15 are in electrical communication with, or otherwise fixed extensions ( conductively) of the switch terminals 11.
    The coil assembly 12 can preferably be designed to comprise a current-conducting coil 16 (with coil assembly 26), a coil core 17, and a coil housing 18 (comprising a coil cover 18 (a) (equipped with coil cover conductor (s) 25) and a coil box or coil base 18 (b)). Coil 16 is wound around core 17, whose core 17 is collinear with a coil axis as in 100. Coil 16 comprises electromagnetic drive terminations as in 19, and core 17 comprises opposite (linearly) core terminations as No. 21.
    Notably, the coil housing 18 has a rotation housing axis 101, whose axis 101 extends orthogonally with respect to the coil axis 100. The rotation housing axis 101 extends through pin structures 22 formed in axial alignment over the coil cover 18 (a) and the coil box 18 (b) of the housing 18, whose pin structures 22 are received in pin receiving structures 23 formed in a support 27 and relay housing 24.
    The first and second pairs of the opposing permanent magnets 13 are respectively and fixedly positioned obliquely (by means of housing anchoring structures 28) adjacent to the core terminations 21 so that the core terminations 21 are respectively displaceable intermediate to the respective magnet pairs 13. Opposite pairs of permanent magnets 13 each comprise substantially flat opposing magnet faces 29, with faces 29 extending at intersection planes 102 thus exhibiting a flat X-shaped configuration as in 103 in Figure No. generally defining the boundaries of the movement of core terminations 21.
    In this last respect, it will be noted that the core 17 has a thickness as in 104, and the magnets 13 are positioned (by means of anchoring structures 28) consequently in order to properly contact the core terminations 21. In other words, the Core 17 preferably comprises substantially flat opposite core faces such as No. 30 so that core faces 30 and magnet faces 29 are similarly angled when contacting each other to maximize contact surface area and reinforcing current flow through the contact surface area intermediate to core 17 and permanent magnets 13.
    It will be understood to form a consideration of the figures that the connecting arms 14 (or connecting arms 14 (a) of the multiple pole modality) work to interconnect the core terminations 21 and spring arms 15. The spring arms 15 each , comprises (i.e., are in electrical communication with or otherwise conductively fixed to) opposite pairs of contacts 31 and a switch terminal as in 11. The opposite pairs of contacts 31 are juxtaposed adjacent to each other so that when mounting switch position is in the closed position, the contacts 31 contact each other as, in general, shown in Figures Nos. 5, 7, 11 and 19. In contrast, the open switch mounting position is generally and comparatively shown in Figures Nos. 4, 6, 10 and 18.
    Coil 16, when supplied with current, works to create a magnetic field as in 105, whose magnetic field 15 is directable through core 17 and cooperable with magnets 13 (as usually pole aligned and shown in Figures Nos. 8 and 9) to transmit rotation of the coil housing (pivot type) (as in 106) on the axis of rotation housing 101. The core terminations 21, consequently, function to displace the connecting arms 14, whose connecting arms 14, in turn Instead, the intermediate spring arms 15 act in the open and closed position as previously referenced. The closed position allows the current to pass through the switch assembly via contacts 31 and switch terminals 11.
    As noted earlier, the connection arms of the assembly 10 are preferably L-shaped from the top plan view and, consequently, comprise a first connection portion as in 32 and a second connection portion as in 33. With assembly 20, the connecting arms 14 comprise a first connecting portion as in No. 34 and a series of second connecting portions as in No. 35 (or a series of interconnected L-shaped structures). The second connection portions 33 and 35 of each 10/20 assembly respectively extend towards each other orthogonal to the first connection portions 32 and 34 of each 10/20 assembly. The core terminations 21 are connected to the first connection portions 32 or 34 and the spring arms 15 extend substantially parallel to the second connection portions 33 or 35 when in an open switch mounting position.
    The spring arms 15 are preferably parallel to each other in the open or closed switch mounting positions and each comprises opposite faces, the internal faces of which 40 face each other as shown in general and referenced in Figures Nos. 10 and 11. Opposite inner faces 40 are magnetically attractive to each other (as generally referenced in 107) during a short circuit scenario, and consequently the magnetically attractive faces 40 function to hold contacts 31 in the closed switch mounting position for a short circuit scenario.
    In this last respect, it is noted that during a short circuit, the magnetic fields generated inside a relay will grow as the current increases. The contacts, however, tend to separate during the current run. To address this structurally, the present invention allows the manufacturer to form a type of contact spring assembly, and to use the same assembly twice as generally shown and illustrated by the spring arms 15, terminals 11 and contacts 31.
    It should be noted that half of the current will flow through the upper contact spring assembly and half of the current will flow through the lower contact spring assembly. Considering that these assemblies are carrying the same current in the same direction, the magnetic forces generated by them are, therefore, equal. This means that when the bottom of the top spring is generating a magnetic field with a south polarity, the top of the bottom spring will generate a magnetic field with a north polarity. Whereas north and south attract (as in 107), the attraction forces contacts 31 to the closed position during a short circuit. The greater the current during the short circuit, the greater the magnetic field; therefore, the magnetic attraction 107 to keep the contacts 31 in a closed position is maximized.
    The contact spring assembly described is similar to the existing assemblies in that the terminals 11 and spring arms 15 are preferably constructed from copper where the spring arm 15 is placed on top of the copper terminal and then riveted together by means of contact buttons 31. Arranging the spring arms 15 so that faces 40 are opposite each other, a resulting contact system allows someone to feed from a copper terminal, then divides the load through two springs and the load comes out again on the other copper terminal. Considering that the two springs (ie, spring arms 15) are preferably identical in terms of fabricability, they will carry a very similar, if not identical, resistance. In addition, these two springs are working directly parallel to each other, resulting in the same magnetic fields generated around the spring arms 15.
    The spring arms 15 preferably comprise first and second spring portions or means for effecting bi-stability. The first spring portions or means are generally contemplated to be exemplified by resiliently tilting the arms 15 as generally shown and referenced in 36. The first spring means are preferably relaxed when in the open switch mounting position and preferably actuated when in a closed switch mounting position, hand not necessarily so. It is contemplated that the first actuated spring means may work well to dampen intermediate contact vibration to the contacts 31 when switching from the open switch mounting position to the closed switch mounting position.
    Second spring portions or means are generally contemplated to be exemplified by resilient spring extensions as generally shown and referenced in 37. Second spring portions or means 37 are preferably relaxed when in an open mounting position and preferably acted when in an switch mounting position closed, but not necessarily configured this way. It is contemplated that the second spring means may work well to reinforce intermediate contact damped vibration to the contacts 31 when switching from the open switch mounting position to the closed switch mounting position.
    It should be noted that the first spring means are preferably operable adjacent to the first connecting portions 32 or 34 and that the second spring means are preferably operable adjacent to the second connecting portions 33 or 35. The first and second spring means consequently come spaced damping means for each pair of contact.
    It is contemplated that the spaced-out damping means may work well to further dampen intermediate contact vibration to the contacts 31 when switching from the open mounting position to the closed switch mounting position 10.
    In this last respect, it should be further noted that each contact pair is preferably positioned intermediate the first and second spaced damping means, whose spaced damping means consequently provide laterally opposite damping means in relation to each contact pair to further reinforce intermediate damped contact vibration to contacts 31 when switching from the open switch mounting position to the closed switch mounting position.
    As noted earlier, a major problem for all electro mechanical switching gears is the contact jump when closing on an electrical charge. To overcome this, the typical structural remedy is to include additional foil or helical springs to cushion the bounce of the contacts. The present invention takes advantage of a simple stamping process that allows the incorporation of an integrated heel reduction spring as exemplified by resilient slopes 36 and resilient extensions 37, whose structural features are spaced laterally in relation to the contacts 31. The present design thus applies contact pressure on both the left and right side of the contact, ensuring equal contact pressure and making sure that the contacts remain closed when the relay is operated.
    Although the above descriptions contain a lot of specificity, this specificity cannot be interpreted as limitations on the scope of the invention, but, on the contrary, as an example of the invention. For example, the invention can be said to essentially teach or disclose an electromagnetic relay assembly comprising a rotating coil assembly, opposite pairs of attractive magnets and a switch assembly.
    The coil assembly comprises a coil, a core, and certain means of rotating the core as exemplified by the rotating coil housing with peripheral pivot-type rotating structures. The core is preferably collinear with or parallel to the coil axis and comprises exposed and opposite core terminations. Notably, the core rotation means has an axis of rotation that extends orthogonally with respect to the coil axis.
    The opposing pairs of attractive magnets are respectively and fixedly positioned adjacent the core terminations so that the core terminations are respectively displaceable intermediate to the magnet pairs. The coil function to create a magnetic field addressable through the core on opposing magnets to transmit rotation on the axis of rotation. The core terminations act on the intermediate switch assembly to an open position and a closed position, the last of whose positions allow the current to pass through the switch assembly.
    The electromagnetic relay assemblies additionally comprise certain connection means and opposite spring assemblies. The connecting means as exemplified by the connecting arms 14 and 14 (a) interconnect the core terminations and spring assemblies. Spring assemblies essentially work to dampen contact vibration when switching from the open to the closed position. The spring assemblies preferably comprise first and second spring means, the means of which are preferably relaxed when in the open position and preferably acted when in the closed position, but the reverse structural configuration, notably that the first and second spring means can be relaxed when in the closed position and actuated when in the open position are also viable alternatives.
    The first and second spring means are spaced from each other opposite the contacts to provide laterally spaced apart damping means to further reinforce the contact pad's vibration of the switch assembly when switching from open to closed positions. The spring arms of spring assemblies are preferably parallel to each other and comprise opposite arm faces as in 40. The opposite arm faces 40 are magnetically attractive to each other during a short circuit scenario, whose magnetically attractive arm turns to maintain the switch assembly in the closed position during the short circuit scenario.
    The attractive magnets comprise faces of opposite magnets, whose faces of opposite magnets are substantially flat and extend in intersecting planes, and the core (terminals) has substantially flat opposite core faces. The contact core faces and magnet faces are similarly angled to maximize contact surface area to further reinforce current flow through the contact surface area intermediate to the core and magnet faces.
    In addition to the following structural considerations, it is further believed that the inventive concepts discussed support certain new methodologies and / or processes. In this regard, it is contemplated that the previous structural considerations support a method for switching an electromagnetic relay comprising the steps of equipping a coil assembly with means for rotating the coil assembly on an axis of rotation orthogonal to the coil assembly axis after which a magnetic field can be created by means of the coil assembly and directed through the coil assembly on opposite magnets to transmit rotation on the axis of rotation. The coil assembly is then rotated (or pivoted) on the axis of rotation, and the switch assembly is actuated intermediate to the open and closed positions by means of the rotation coil assembly.
    The method is believed to further understand the step of dampening contact vibration by means of opposite contact spring assemblies when shifting the switch assembly from the open to the closed position, which may involve the step of laterally spacing the damping means in relation to the contacts of the switch assembly before the step of dampening contact vibration. Certain faces (as in # 40) of the contact spring assemblies can be opposed before the damping contact vibration step so that the opposite faces are magnetically attractive to each other during a short circuit scenario to keep the switch assembly in position closed during that scenario.
    Although the invention has been described by reference to a number of modalities, it is not intended that the new device or relay be limited by it, but that modifications of them are intended to be included as they fall within the broad scope and spirit of the previous disclosure. and attached figures. For example, the previous specifications support an electromagnetic relay assembly primarily intended for use as a single pole relay assembly as in No. 10. It is contemplated, however, that the essence of the invention can be applied in multiple pole relay assemblies as, in general, exhibited and referenced by assembly 20, having a unique interpretation and functionality in its own right, but which are made possible by the teachings of the single pole modality first shown in this disclosure.
