    [1] The present invention relates to electrical modules in general.
    [2] Modular electrical plugs and sockets for professional use are known. However, standardized plugs and sockets are generally too large to be able to achieve a space-efficient modular solution for household use. For example, the use of a device connector socket / plug, such as IEC Cl 9 / C20, would ensure that the system was started to be able to be compared with non-modular socket holders.
    [3] The use of industrial plugs and sockets, such as the standard, flat 3-pole connectors, would also make the 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 either because ofits welding mechanism which requires a rotating movement to engage and for a modular electrical system, it is most advantageous for the user to have an axial movement for contacting one module to the 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 for it to be safe for household use.
    [7] An object of the present invention is to provide an electrical module with a space-saving connection between two electrical modules with a high safety level lamped for household use.676802
    [8] According to the invention, there is provided an electrical module comprising a first cradle with a plug interface, the plug interface comprises a plurality of plug pins and a collar surrounding the plug pins, the collar has a mantle surface, a second cradle with a socket branch section, a recess having a plurality of receptacles adapted to receive plug pins on an adjacent electrical module, and the recessed end is surrounded by a recess recess provided in the second cradle and adapted to receive a collar on an adjacent electrical module, used in the plug fitting with an outlet interface on a corresponding electrical module and the outlet interface is adapted to be connected to a plug interface on a corresponding electrical module, the electrical module being characterized in that an MO slope is arranged on the mantle surface on the collar.
    [9] Such a curved slope helps in the avoidance of a so-called"jumper load", to avoid jamming when the longitudinal axes of the two modules are not exactly parallel to each other.
    [10] In a preferred embodiment, the slope is provided with a steeper slope closer to the first cradle, whereby the distance between the collar and the recess cradle on the outlet module increases rapidly when the two modules move inward.
    [11] In a preferred embodiment, the collar is provided with a first welding means and the take-out end is provided with a second welding means, and used in the first welding means is adapted to engage with a second welding means on an interconnecting plug connector adapted to engage with a second welding means. on a socket on a corresponding electrical module, give the user tactile and audible feedback that the connector or module is fully inserted. These welding means increase the cohesive 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 disconnection when exposed to unintentional axial forces.676803
    [12] In a preferred embodiment, the collar ledge is arranged at the inner portion of the collar where the circumference of the collar is constant in the axial direction of the module and usual in the outlet recess is arranged in the outlet recess cradle on the outermost portion of the outlet recess. When excessive force is applied to adjacent modules, the plug ledge and the cradle connect ice and form one on the slope of the collar and the cradle on the outlet recess forces the modules to separate completely so that no permanent damage is caused to the parts.
    [13] In a preferred embodiment, the outlet recess assay rate is shorter thanthe collar ledge, creating a small space between two adjacent modules. Thus, when subjected to a bending force, e.g. when a pressure is applied from above to the coupling between the two adjacent modules, the risk of the modules moving slightly is reduced, ie. de bOrjar is disconnected.
    [14] In a preferred embodiment, the plug pins comprise onecenter plug plug pins, preferably grounded, and two phase plug pins for a respective electrical phase, and vane in the outlet hall includes a center socket hall, preferably for ground, and ty6 'phase socket hF for a respective electrical phase. This provides a space-efficient electrical interface between two adjacent modules.
    [15] [0015] In a preferred embodiment, a bottom of the module is provided with an opening in line with the outlet sand. This provides space for bending that occurs when connecting and uncoupling two modules, and also provides access to the outlet sand during manufacture.
    [16] In a preferred embodiment, an upper side of the electrical module is provided with an electrical device, preferably a standard electrical electrical outlet, a switch, or a display. This provides easy access to the functions of the module.676804
    [17] In a preferred embodiment, the first and second cradles are arranged on opposite sides of the electrical module. A series of modules with electrical devices for the same or different function can thus be created.
    [18] The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
    [19] Figs. 1 and 2 are perspective views of an embodiment of the socket module in accordance with the present invention;

    [24] Fig. 10 shows a schematic perspective view of the inner body of the socket shown in Fig. 9, but with a hatch in an open position.
    [25] In the following, a detailed description of an electrical module and connectors in accordance with the invention will 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 .. Space indications such as "byre" or "lower" refer to the directions shown in the figures. .67680
    [26] An electrical module, generally designated 10, is shown in Figs. 1 and 2.
    [27] Referring to Fig. 1, the plug cradle 12 is provided with aplug 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 IEC 60320 standard and positioned with a minimum distance based on the minimum the creep or spacing distance specified in IEC 60320 - connection tolerances. In a preferred embodiment, the relative 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 current conducting plug pins 22a, b and to provide interconnecting means for interconnection with an additional module, which will described below. The collar 24 is provided with an orientation indicator 24a in the form of a socket in the mantle surface of the collar 24. The orientation indicator 24a facilitates the 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.
    [28] 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 and one of the plug pins 22a, b for676806the plug interface 20. The socket 32a, b are arranged in a socket 34 with a size and shape adapted to be received in and surrounded by the collar 24 on the plug interface 20. The socket 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 provide the user with 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.
    [29] The recess sand 34 is surrounded by a recess recess 38, with a recess cradle 38a having a ledge-shaped outer portion 38b.
    [30] 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 for connecting and disconnecting two modules, thus allowing some flexibility for the collar 24. passing Committee 36, which will be described below.
    [31] The interconnection and co-coupling of two adjacent electrical modules 10 ', 10 "will now be described in detail with reference to Figs. 3-6.
    [32] In Fig. 3, the modules 10 ', 10 "are shown somewhat separated for interconnection or combining 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 on the socket interface 30 engages with welding depth 26 on the plug interface, increasing the strength of676807the interconnection between the two modules 10 ', 10 "to prevent inadvertent co-coupling of the two modules.
    [33] 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 recess end 34 engages the recess. 26 on the collar 24. The design of the collar 24 with the curved slope 24b helps to avoid so-called "bureau load effect", ie to avoid clamping when the longitudinal axes of the two modules 10 ', 10 "are not exactly parallel to each other.
    [34] When two adjacent modules 10 ', 10 "experience a bending force, toFor example, when a pressure is applied from above to the connection between the two adjacent modules, there is a risk that the modules will move slightly, they will start to disengage.
    [35] To avoid this type of sarcophagus, the modules 10 ', 10 "are manufacturedsaid that there is a small gap between the cradles 12, 14 when the modules are interconnected. This gap prevents the cradles from pressing against each other, which in turn prevents the plug interface and the socket interface from sarconnecting when a small force is applied to them, for example when holding a module when removing a plug from the other module. At this displacement, the contact area between the surfaces of the plug interface 20 and the socket interface 30 increases and also the pressure between the surfaces increases, which in turn increases the frictional force holding the modules together. The ratio of the clearances between the surfaces of the plug interface 20 and the socket interface 30, and the distance from the center of rotation out to the corners of the cradles 12 and 14 gives the size of the gap needed to prevent the corners of the cradle 12 and 14 from coming into contact with the surfaces described above. 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.
    [36] In the event that the modules are exposed to Excessive forces, interruption ofportions of the modules by means of the design of the collar 24. As shown in Fig. 3, to676808For example, the collar 24 is formed with a sloping portion 24b on the upper portion thereof. In other words, the collar has a circumference that decreases with the distance from the base clarav, ie. 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 extent of the module. The cradle 38a, 38b on the outlet recess 38 on the outlet interface 30 has a nearly complementary design, as best shown in Fig. 4, with a curved portion 38a and an outlet recess ledge 38b with a constant radius in the axial elongation of the module extending into the outlet recess. the part of the outlet depression 38.
    [37] The above-mentioned gap is preferably achieved by making the ledge 38b on the outlet recess shorter than the ledge 24c on the collar 24. Alternatively or additionally, this is accomplished by making the transducer and representing step 24c on the collar 24 longer than step 38b on the outlet recess 38 and thereby moving the entire plug interface 20 out of the plug cradle 12, potentially in combination with the release 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 connecting connector sockets (not shown in the figures) is also possible. The bottom should appear before the plug cradle 12 and the socket cradle 14 contact each other.
    [38] The combination of an inclined or sloping portion and a ledge portion pathe collar 24 in combination with the design of the recess wall portions 38a, 38b of the socket has proved to be advantageous in the transfer of bending loads between the modules. For example, a mold one on the collar 24 is designed so that it does not break during buoyancy and so that it can transfer load to an adjacent module and when subjected to high buoyancy loads, separate the modules. This will be explained in detail below.676809
    [39] A forced separation of the two modules 10 ', 10 "starts the tan 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 is resting on the floor and the other end is resting on a sill and then when the flap tram is paired in the middle.When the force increases, the collar 24 begins to Bend due to bending forces caused by the rotation of the inlets of the modules.When the rotation has reached a certain level at night, the ledges 24c and 38b are connected to ice.
    [40] At this point, the two modules 10 ', 10 ", shown in Fig. 6, separate. The beneficial effect of the separation is facilitated by the fact that the slope 24b is curved, with a steeper slope closer to the plug cradle 12, whereby the distance between the collars 24 and the recess cradle 38a on the socket module 10 "moves rapidly when two modules 10", 10 "are moved.
    [41] Thus, when excessive force is applied to the two modules 10 ', 10 ", the plug step 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 the flake does not permanently damage. the parts.
    [42] 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 42a are b, each of which is 44 provide protection for a user saying 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 mantle surface of the collar 44. The orientation indicator 44a facilitates the correct orientation of an interconnecting67680socket connector shown in Fig. 8. The collar 44 is also provided with a welding recess 46 adapted to receive a projection on an interconnecting socket connector.
    [43] Further to Fig. 8, a cable connector socket, generally designated 50,comprises three socket holes 61, an upper center h6152a for ground and two lower holes 52b for a respective electrical phase, each adapted to receive a respective one of three contact pins on a plug interface. 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 socket 54 is provided with a locking projection 56 (not shown in Fig. 8) adapted to be received in the recess on an interconnecting plug interface. The interior of the socket 54 is provided by a housing 54b which is provided with an orientation indicator in the form of a socket 54a.
    [44] The socket interface 50 for the cable connector socket will now be described in detail with reference to Figs. 9 and 10, shown in Fig. 9 showing the socket interface without cover and with a door in a first end position while Fig. 10 is a similar view but with the door in a second andposition.
    [45] 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 socket sharks, respectively. In front of the socket housing, a hatch 58 arranged vertically movable between a first lower end layer, in which it tackles the two lower socket holes 52b, is shown in Fig. 9, and an upper end portion, in which no socket hall is thanked, is shown in Figs. 10. The function of the lid 58 is to prevent inadvertent insertion of objects into the socket 52a, b and into contact with the inner flowing inner liners 53 therein.
    [46] To realize the movement from the lower end position to the upperthe front position, the front surface of the door is provided with two inclined or beveled surfaces 58a, each adapted to cooperate with the spirit on a respective plug pin upon its insertion into the socket interface 50. More preferred, on6768011due to the inclination of the inclined surfaces 58a, when connected to a plug interface, the plug pins push the cover 58 upwards from 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 andposition as long as the plug and socket branches intersect, ie. s6 'long as the plug pins protrude into the lower sockets 52b.
    [47] To ensure that the cover 58 is in its lower end position when nothingplug pins are inserted into the socket hall, biasing means in the form of two hatch springs 60 are arranged in the socket interface 50; one on each side of the bye socket 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 interconnected by a coil 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 stored at or supported at its central 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 tensioned by the door spring 60.
    [48] By providing two door springs 60, one on each side of the center outlet hinge 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 that case a force is avoided. applied to only one of the inclined surfaces 58a of the door. In this case, the door 58 is inclined either to the left or to the right due to the support of 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.
    [49] 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 10.6768012
    [50] Preferred embodiments of an electrical module and connectors have 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 show connectors with two phases and a ground, it will be appreciated that the invention is also applicable to unearthed devices showing 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.
    [51] A specific torsion spring device has been described. It will be appreciated thatthis can be varied, 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.
    [52] 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 cradle cradles and / or socket cradles.
    [53] Although the welding 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.6768013
