    [1] The present invention relates to electrical modules and connectors in general.
    [2] Modular electrical plugs and sockets for professional use are kanda. However, standardized plugs and sockets are generally too large to provide a space-efficient modular solution for household use. For example, using a device connector socket / plug, such as IEC Cl 91C20, would cause the system to become too large to be inserted into non-modular socket holders.
    [3] The use of industrial plugs and sockets, such as the standard, flat 3-pole connectors, would also make the Ora system too large and this type of connector is usually not suitable for transferring buoy packing loads from one module to another.
    [4] An industrial connector would also not be suitable both because of its locking mechanism which requires a rotary movement to engage and for a nodular electrical system it is next to advantageous for the user to have an axial movement for contacting a module to it. Other.
    [5] Furthermore, the above-mentioned connectors have no cover protecting the flowing connector sockets.
    [6] There are smaller connectors than those described above, but they are not intended for such high loads as 250 V and 16 A, which is necessary for such a modular system in order for it to be safe for household use.
    [7] A key object of the present invention is to provide the smallest possible connection between two cables and also a space-saving connection between two electrical modules with a high level of safety for household use.
    [8] In accordance with the invention, there is provided an electrical connector comprising a socket provided with a socket for receiving connector pins for an interconnecting connector, a gap provided movable between a first end position in which it terminates the socket, and a second end position in which no sockets are provided, and biasing means adapted to bias the cover towards the first end position thereof, used in the electrical connector, may be characterized in that the biasing means comprises at least one torsion spring.
    [9] By providing the biasing member as a torsion spring, the connector can be provided with a very small size.
    [10] In a preferred embodiment, the torsion spring has a first leg and a second leg interconnected by a torsion spring portion. The torsion spring portion is preferably supported by a pin extending horizontally in the electrical connector, transverse to the extension of the socket tail. In this configuration, the torsion spring can be arranged to engage with the door without compromising the dimensions.
    [11] In a preferred embodiment, the first leg is stationary and the second leg rests on an upper end portion of the lid. This gives a force acting on the lid, which is within a desired interval, regardless of the position of the lid.
    [12] In a preferred embodiment, the two torsion springs are arranged, giving a balanced door movement.
    [13] In a preferred embodiment, the front surface of the door is provided with two inclined surfaces, each adapted to cooperate with the tip of a respective plug pin when it is inserted into the respective socket hole. This provides a secure opening for protecting a user from power hazards.
    [14] In a preferred embodiment, the outlet hall comprises a center outlet hall, preferably for ground, and two phase outlet halls for a respective electrical phase, usually in a torsion spring arranged on [Dada sides of the center outlet hall. This is a space-saving configuration, allowing small dimensions of the electrical connector. The inboard distance for the two phase sockets is about 3 millimeters and the distance between the center tail and each of the two phase sockets is about 4 millimeters, thus adhering to the current safety regulations.
    [15] In a preferred embodiment, an electrical connector in accordance with the invention is included in an electrical module.
    [16] The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
    [17] Figs. 1 and 2 are perspective views of an embodiment of the socket module in accordance with the present invention;

    [23] In the following, a detailed description of an electrical module and connectors according to the invention can be given. The term "electrical module" should in this context be interpreted as which module has one or more electrical plug and / or socket connectors, night voltage connectors, power switches, etc .. Also space indications such as "Upper" or "lower" refer to the directions shown in the figures. .
    [24] An electrical module, generally designated 10, is shown in Figs. 1 and 2.
    [25] Referring to Fig. 1, the plug cradle 12 is provided with a plug interface, generally designated 20. The plug interface comprises three plug pins 22, an upper centered pin 22a for ground and two lower pins 22b for a respective electrical phase, arranged in accordance with with IEC 60320 standard and positioned with a mutual resistance based on the minimum allowable creep or spacing distance specified in IEC 60320 - connection tolerances. In a preferred embodiment, the inboard distance of the two lower pins is about 3 millimeters and the distance between the upper center pin and each of the two lower pins is about 4 millimeters. The plug pins 22a, b are surrounded by a collar, the function of which is both to provide protection for the user so that he or she avoids direct contact with the conductive plug pins 22a, b and to provide interconnecting means for connection with an additional module, which will to be described below. The collar 24 is provided with an orientation indicator 24a in the form of a socket in the jacket surface of the collar 24. The orientation indicator 24a facilitates correct orientation of an interconnecting socket connector (not shown in Figs. 1 and 2) to provide tactile feedback. The collar 24 is also provided with a welding means in the form of a welding recess 26 adapted to receive a projection on an interconnecting socket connector, which will be described below.
    [26] Further to Fig. 2, the socket cradle 14 is provided with a socket interface, generally designated 30. The socket interface comprises three socket holes 32a, b, each adapted to receive one respective of the plug pins 22a, b for the plug interface 20. The socket hall 32a, are arranged in a recess 34 with a size and shape adapted to be received in and surrounded by the collar 24 on the plug interface 20. The recess is provided with a welding means in the form of a welding projection 36 adapted to be received in the recess 26 on an interconnecting plug connector. The welding recess 26 and the lasing projection 36 together give the user a tactile and audible feedback that the connector or module is fully inserted. They also increase the holding force between the plug and the socket, both when used as a cable connector or as a connector between modules. This increases the tolerance for unintentional release when subjected to unintentional axial forces.
    [27] The take-out sand 34 is indicated by a take-out recess 38, with a recess cradle 38a with a ledge-shaped outer portion 38b.
    [28] The bottom of the module 10 is provided with a fastening interface 18 facilitating fastening of the module 10 to a cradle, a table surface or the like. In the embodiment shown, the fastening interface 18 comprises four hales adapted to receive fastening means such as hooks or the like. Finally, the bottom of the module 10 is also provided with an opening 19 in line with the socket 34. This opening 19 allows access to the socket 34 during manufacture and also provides space below the socket when connecting and disconnecting two modules, thereby allowing some flexibility for the collar 24. passing Committee 36, which will be described below.
    [29] The interconnection and sarconnection of two adjacent electrical modules 10 ', 10 "will now be described in detail with reference to Figs. 3-6. 67437 6
    [30] In Fig. 3, the modules 10 ', 10 "are shown somewhat separated for interconnection or joining of the plug interface 20 on the first module 10' and the socket interface 30 on the second module 10". For interconnection, the plug pins 22a, b on the first module 10 'are aligned with the socket on the second module 10 "and the two modules are then easily compressed to the position shown in Fig. 4. In this position, the welding projection 36 engages the socket interface 30. with the welding recess 26 on the plug interface, increasing the strength of the interconnection between the two modules 10 ', 10 "to prevent inadvertent co-coupling of the two modules.
    [31] Intentional disconnection of the two modules 10 ', 10 "is easily accomplished by pulling the two modules in opposite directions from the position shown in Fig. 4. The user will then experience a tactile feedback when the projection 36 on the take-out end 34 engages with the recess 26 on the collar 24. The design of the collar 24 with the curved slope 24b helps to avoid so-called "bureau loading effect", i.e. to avoid clamping when the longitudinal axes of the two modules 10 ', 10 "are not exactly parallel to each other. .
    [32] When two adjacent modules 10 ', 10 "experience a bending force, for example when a pressure is applied from above to the coupling between the two adjacent modules, there is a risk that the modules move slightly, they are polar to go out intervention.
    [33] To avoid this type of sarcophagus, the modules 10 ', 10 "are made so that there is a small nnellanrunn between the cradles 12, 14 when the modules are interconnected. This gap delays the cradles from pressing against each other which in turn prevents the plug interface and the outlet interface from the coupling when a small force is applied to them, for example when holding a module when removing a plug from the other module.In this displacement the contact area between the surfaces of the plug interface 20 and the outlet interface 30 and also the pressure between the surfaces increases the ratio of the clearance between the surfaces of the plug interface 20 and the outlet interface 30, and the distance from the center of rotation to the corners of the cradles 12 and 14 gives the size of the gap needed to avoid the corners of the cradle 12 and 14 in contact, the surfaces described above are clamped as in Fig. 5. In the geometry shown in Fig. 4, this gap is determined to be 0.4 mm, but could vary between 0.1 and 0.8 mm, more preferably between 0.2 and 0.6 mm.
    [34] In case the modules are subjected to excessive forces, interruption of patches on the modules is avoided by the design of the collar 24. As shown in Fig. 3, for example, the collar 24 is formed with a sloping pat 24b on the upper portion thereof. In other words, the collar has an onn circle which decreases with the distance than the base thereof, i.e. with the distance from the plug cradle 12 on the module. At the inner portion of the collar there is a collar ledge 24c used in the circumference of the collar is constant in the axial extension of the module. The cradle 38a, 38b on the outlet recess 38 on the outlet interface 30 has an almost complementary design, as shown in Fig. 4, with a bend 38a and an outlet recess ledge 38b with a constant radius in the axial extension of the module used in the outlet recess 38. the portion on the outlet recess 38.
    [35] The above-mentioned nunnal run is preferably achieved by making the ledge 38b on the socket recess shorter than the ledge 24c on the collar 24. Alternatively or additionally, this is accomplished by making the transducer and representing the step 24c on the collar 24 longer than the step 38b on the socket recess 38 and thereby moving the entire plug interface 20 out of the plug cradle 12, potentially in combination with the unloading shown in Fig. 4. Yet another alternative is to axially extend the socket end 34 outside the socket cradle 14 while the bottom surface of the interconnecting plug interface 20 is still aligned with the plug cradle 12. out the collar 24 axially from the plug cradle, or the reverse by shortening the recess cradle 38a, possibly in combination with other alternatives. The dimensioning of the relationship between the plug pins 22a and 22b so that they bottom in the interconnecting connector sockets (not shown in the figures) is also possible. The bottom bar appeared before the plug cradle 12 and the socket cradle 14 contacts each other. 67437 8
    [36] The combination of an inclined or sloping portion and a ledge portion on the collar 24 in combination with the design of the recess wall portions 38a, 38b of the socket has proved advantageous in transferring buoy loads between the modules. For example, the shape of the collar 24 is designed so that it does not break during buoy loading and so that it can transfer load to an adjacent module and when subjected to high buoy loads, separate the modules. This will be explained in detail below.
    [37] A forced separation of the two modules 10 ', 10 "starts the Than position in Fig. 4. From this position, used in the two modules are essentially in the same plane, the loaded ones described above are shown in Fig. 5. This load situation can occur when two or more modules are supported only at each end, for example when one side rests on the floor and the other end rests on a sill and then when someone steps on the middle. Due to the buoyancy forces caused by the rotation of the nodules inboard, when the rotation has reached a certain level, the ledges 24c and 38b are coupled to the ice.
    [38] At this point, the two modules 10 ', 10 "separate, shown in Fig. 6. The beneficial effect of the separation is facilitated by the fact that the slope 24b is bent, down a steeper slope closer to the plug cradle 12, whereby the distance between the collars 24 and the recess cradle 38a on the outlet module 10 "moves rapidly when two modes 10", 10 "are moved.
    [39] Thus, when excessive force is applied to the two modules 10 ', 10 ", the plug stage 24c and the cradle step 38b freeze and the shape of the slope 28b on the collar and the cradle 38a on the outlet recess forces the modules to separate completely so that no permanent damage occurs to the parts.
    [40] Further to Figs. 7 and 8, a plug interface in the form of a cable connector plug and a socket interface in the form of a cable connector socket will be described. The cable connector plug, generally designated 40, is adapted to be attached to the duct portion of a plug connector cable 41, and includes three plug pins 42a, b arranged in the same manner as the plug pins arranged in the plug interface 20. The plug pins 44 are each of a function 42, b is to provide protection for a user so that he or she avoids direct contact with the conductive plug pins. The collar 44 is provided with an orientation indicator 44a in the form of a socket in the nan surface of the collar 44. The orientation indicator 44a facilitates correct orientation of an interconnecting socket connector shown in Fig. 8. The collar 44 is also provided with a welding recess 46 adapted to receive a socket 46. an interconnecting socket connector.
    [41] Further to Fig. 8, a cable connector socket, generally designated 50, comprises three socket halls, an upper center hall 52a for ground and two lower halls 52b for a respective electrical phase, each adapted to receive one and three connector pins on a plug interface, respectively. . The socket holes 52a, b are arranged in a socket 54 with a size and shape adapted to be received in the collar of a plug interface. The take-out sand 54 is provided with a welding projection 56 (not shown in Fig. 8) adapted to be received in the recess on an interconnecting plug interface. The interior of the socket tip 54 is thanks to a housing 54b which is provided with an orientation indicator in the form of a socket 54a.
    [42] The socket interface 50 for the cable connector socket can now be described in detail with reference to Figs. 9 and 10, shown in Fig. 9 showing the socket interface without housing and with a door in a first end position while Fig. 10 is a similar view but with the door in a second andposition.
    [43] The outlet interface 50 is provided with three outlet halls 52a, b described above with reference to Fig. 8. These sockets extend all the way through the socket interface 50 and each houses an electrically conductive, substantially tubular inner liner 53 arranged to establish electrical connection with interconnecting plug pins which have been inserted into one and one of the sockets, respectively. In front of the outlet hall, a hatch 58 arranged vertically movable between a first lower end member, in which it tackles the two lower outlet holes 52b, is shown in Fig. 9, and an upper end portion, in which no outlet hall is thanked, is shown in Fig. 10. The function of the cover 58 is to prevent inadvertent insertion of objects into the socket 52a, b and into contact with the internal flowing inner liners 53 therein.
    [44] In order to realize the movement Iran the lower end position to the upper end position, the front surface of the door is provided with two inclined or beveled surfaces 58a, each adapted to cooperate with the spirit of a respective plug pin upon its insertion into the socket interface 50. M preferably, due to the inclination of the inclined surfaces 58a, when interconnected with a plug interface, the plug pins push the door 58 upwards than its lower end position, shown in Fig. 9, to its upper end position, shown in Fig. 10. The door 58 is maintained in its upper and position as long as the plug and socket interfaces interlock, ie. as long as the plug pins protrude into the lower sockets 52b.
    [45] To ensure that the door 58 is in its lower end position when no plug pin is inserted into the socket, biasing means in the form of two door springs 60 are provided in the socket interface 50; one on each side of the upper outlet tail 52a. Thus, the door springs bias the door towards the first lower end position thereof. The door springs 60 are in the form of so-called torsion springs, in this embodiment springs used in two legs extend in different directions and two legs are connected by a helical spring. In the embodiment shown, each door spring 60 has a first leg 60a abutting a vertical rear cradle 62 on the outlet interface and a second leg 60b resting on the upper end portion 58b of the door. Each hatch spring 60 is mounted at or supported at its center portion, i.e. a coil spring portion or torsion spring 60c, of a pin 64 extending horizontally into the socket interface transverse to the extension of the socket hole 52. With this configuration, the door is biased by the door spring 60.
    [46] By providing two door springs 60, one on each side of the center outlet tail 52a, in combination with ledges 66 and a flange 59 arranged in the surface on which the door 58 slides, unintentional movement upwards of the door 58 in case a force is applied to it is avoided. only one of the inclined surfaces 58a of the door. In this case, the door 58 is inclined either to the left or to Niger due to the support for the vertical flange 59 and the upward movement thereof is prevented by one of the ledges 66 engaging the upper end portion of the door.
    [47] Although the socket interface 50 on the cable connector socket has been described in detail, it will be appreciated that this description is also applicable to the construction of the socket interface 30 on the electrical module 10.
    [48] The preferred embodiment of an electrical module and connector has been described. It will be appreciated that these may be modified within the scope of the appended claims without departing from the spirit of the invention. Thus, although the described embodiments provide connectors with two phases and one ground, it will be appreciated that the invention is also applicable to unearthed devices having only two plug pins and corresponding hal or other configurations. Also, although embodiments with two torsion springs biasing the cap on the outlet connector have been described, it will be appreciated that a single torsion spring may also be used.
    [49] A specific torsion spring device has been described. It will be appreciated that this may vary, e.g. with the first leg abutting a support other than the vertical rear cradle on the outlet interface. Instead, the first leg of the torsion spring can rest against any other surface that is raised or fixed, as long as it remains stationary while the second leg moves with the lid.
    [50] The electrical module has been shown with the plug cradle and the socket cradle on opposite sides of the module. When interconnected, a plurality of electrical modules will form a row of modules. However, an electrical module in accordance with the invention may also be provided with other configurations of plug cradles and socket cradles, such as a plug cradle and a socket cradle on adjacent sides of the module or a plurality of plug cradles and / or socket cradles.
    [51] Although the laser means has been described as a recess in the collar of the plug interface and a projection on the socket, it will be appreciated that the opposite configuration, i.e. with a protrusion on the collar of the plug interface and a recess in the outlet, it is also possible. 67437 13
