Description

Technical Field

[0001] The present invention generally relates to the field of female electrical connection terminals for sockets, i.e. electrical connection terminals equipped to sockets, and the functional part thereof includes a receiving recess designed to receive the pins of an electrical plug, thereby supplying power to an electrical device connected to the electrical plug.

[0002] More specifically, the present invention relates to a receptacle mechanism comprising an insulating base accommodating at least one female electrical connection terminal including at least one conductive element. On one hand, the conductive element defines a first insertion portion (location, place, position) intended to receive a connecting pin of an electrical plug for establishing electrical contact between the connecting pin and the conductive element. On the other hand, the conductive element defines a second insertion portion, distinct from the first insertion portion, intended to receive an electrical conductor for establishing electrical contact between the electrical conductor and the conductive element. The first insertion portion is accessible (operable, touchable) from a first surface of the female terminal via an inlet opening, and the second insertion portion is accessible from a second surface of the female terminal opposite to the first surface via an access opening different from the inlet opening. Background Technology

[0003] The function of electrical connection terminals in a socket is to transmit current from an electrical conductor originating from an electrical network to an electrical plug inserted into the socket socket, thereby powering the electrical device connected to the plug. The socket mechanism includes an insulating base housing two female electrical connection terminals, one supplied with neutral current from the electrical network and the other with live current. The insulating base is designed to be housed within an electrical housing to which the electrical conductor originating from the electrical network reaches. The free end of the electrical conductor inserted into the terminals is forced into an orientation imposed by the terminals, while the remaining length of the conductor is pressed into the bottom of the electrical housing and located at the rear of the insulating base of the device mechanism. Between these two areas, the electrical conductor naturally bends. Naturally, the natural curvature of the electrical conductor depends on its cross-section, and thus the volume (outer dimensions) (also called the "total volume") of the bent portion of the electrical conductor varies depending on the size of the cross-section of the electrical conductor.

[0004] In document FR3060873, a female electrical connection terminal for a socket is known as described in the technical field section. The female electrical connection terminal in FR3060873 is bulky, resulting in a cumbersome insulating base for the socket mechanism it equips, and leaving very little space at the bottom of the electrical housing. This space is insufficient to accommodate the bending of the electrical conductor caused by the terminal connection, and also insufficient to press in the length of the electrical conductor that enables the connection. This becomes even more difficult when the electrical housing receiving the socket mechanism is shallow. Summary of the Invention

[0005] To overcome the aforementioned shortcomings of the prior art, the present invention proposes a socket mechanism that includes a small-volume female electrical connection terminal, with space released at a second surface located at the rear of the female terminal to facilitate connection of an electrical conductor supplying power thereto, and to accommodate the natural curvature of the electrical conductor.

[0006] More specifically, according to the present invention, a socket mechanism is provided having a female electrical connection terminal as described in the Technical Field section, wherein a first plane includes an edge defining an inlet mouth portion for entering a first insertion portion and extends perpendicularly to the insertion direction of the prong into the first insertion portion; a second plane is parallel to the first plane and the distance between the second plane and the first plane is less than or equal to 9 mm, the second plane including all or part of an edge defining a proximity opening of a second insertion portion; wherein an insulating base defines a receiving opening at the front for receiving a socket decorative panel and includes a bottom wall extending along at least a portion of a second surface of the female terminal and including a misaligned portion misaligned (recessed, retracted) toward the receiving opening, in which an insertion opening is provided facing the proximity opening of the second insertion portion of the female terminal; the insertion opening is defined by an edge at least partially included in a third plane, the third plane being parallel to the second plane and spaced apart from the second plane by the thickness of the bottom wall; a fourth plane is at least 2 mm away from the third plane, parallel to the third plane, and includes the portion of the bottom wall of the insulating base furthest from the receiving opening.

[0007] Therefore, in the socket mechanism according to the invention, the second plane of the female terminal is closer to the first plane, thereby freeing up space at the rear of the female connection terminal. The freed space facilitates the connection of the female terminal and can accommodate the bent portion of the electrical conductor supplying power to it.

[0008] Advantageously, the distance between the first and second planes of the female terminal can be zero, so that the second plane coincides with the first plane. According to one embodiment of the invention, the distance between the first and second planes can even be negative, that is, the second plane is located in front of the first plane. Both configurations free up more space at the rear of the female terminal.

[0009] Preferably, the space released at the rear of the terminal is calibrated to fully accommodate the total volume occupied by the bent portion of the electrical conductor.

[0010] Advantageously, the base of the socket mechanism is designed to accommodate the female terminal and follows the forward offset of the second plane of the female terminal, thereby freeing up space at the bottom of the electrical housing. The electrical housing receives the base, and the thickness of the bottom wall separating the second and third planes ensures the function of guiding the electrical conductor to the second insertion portion of the female terminal. The space freed up at the bottom of the housing can accommodate the curved portion of the electrical conductor supplying power to each female terminal without compression. The guidance for the electrical conductor facilitates the connection of the electrical conductor in the female terminal without affecting the natural curvature of the electrical conductor.

[0011] Other non-limiting and advantageous technical features of the socket mechanism according to the invention—features that can be applied individually or in combination in a technically possible manner—are as follows:

[0012] - The female electrical connection terminal has a height between 5mm and 9mm, and its second surface includes an outlet opening of the first insertion part facing the inlet of the first insertion part;

[0013] -The edge defining the outlet opening of the first insertion portion of the female terminal is included in the second plane;

[0014] - The insertion direction of the electrical conductor into the second insertion part of the female terminal through the proximity opening of the female terminal is inclined at an angle of less than or equal to 45° relative to the axis perpendicular to the second plane;

[0015] - The conductive element of the female terminal defines a third insertion portion designed to receive a bridging electrical conductor to establish an electrical contact between the bridging electrical conductor and the conductive element. The third insertion portion is accessible from the second surface of the female terminal via different second access openings, and all or part of the edges defining the second access openings are included in the second plane.

[0016] - The conductive element of the female terminal is partially formed of a metal strip having a portion connected to the portion of the conductive element defining the first insertion portion and thereafter a first raised portion and a second raised portion. The concave surface of the first raised portion faces the inlet of the first insertion portion and a resolution opening for the second insertion portion of the female terminal is provided therein. The concave surface of the second raised portion faces away from the inlet of the first insertion portion, and electrical contact between the electrical conductor and the metal strip is intended to be established against the concave surface of the second raised portion.

[0017] - A channel opening is provided in the bottom wall of the insulating base, and the channel opening faces the outlet opening of the first insertion part;

[0018] - The channel opening is sealed by a membrane made of a deformable and electrically insulating material;

[0019] - The bottom wall of the insulating base is provided with a plurality of insertion openings, each defined by an edge at least partially included in a third plane. One of the insertion openings can be used to access a male electrical connection terminal, which includes an electrical contact element protruding from the interior space of the insulating base and is designed to receive a decorative panel.

[0020] - The public electrical connection terminal includes at least one conductive element, which is connected to the electrical contact element on one hand and defines an electrical cavity for receiving an electrical conductor on the other hand, for establishing an electrical contact between the electrical conductor and the conductive element. The electrical cavity is accessible via an access opening defined in the conductive element by an edge at least partially included in a plane parallel to the third plane and spaced apart from the third plane by the thickness of the bottom wall of the insulating base.

[0021] - At least one insertion opening provided in the bottom wall of the insulating base forms a guide channel, a portion of which extends obliquely relative to the central extension axis of the guide channel;

[0022] The insertion opening is defined by an edge comprising two portions offset from each other along the central extending axis.

[0023] Finally, the present invention relates to a socket, which, on the one hand, includes a device support accommodating a socket mechanism according to the invention, and on the other hand, includes a decorative panel defining a socket for an electrical plug, the decorative panel having a bottom wall with an opening for accessing a female electrical connection terminal disposed in an insulating base of the socket mechanism.

[0024] Of course, different features, variations and embodiments of the present invention can be associated with each other in various combinations, as long as they are not incompatible or mutually exclusive. Attached Figure Description

[0044] It should be noted that in these figures, structural and / or functional elements common to different variations may be labeled using the same reference numerals. Detailed Implementation

[0045] exist Figure 11 and 13 The image shows a socket 1 according to the present invention.

[0046] In this case, it is a socket to be installed into the receiving wall.

[0047] The socket 1 includes a socket mechanism 3000; 4000, which is enclosed by a decorative panel (veneer panel) 8 and attached to the device support 3.

[0048] The equipment support 3 is used to mount the base of the socket mechanism into the electrical housing 5 to be fitted into the receiving wall.

[0049] Decorative panel 8 defines the socket 9 (see) Figure 11 and 13 Users can connect electrical plug 6 (see) Figure 3 Insert it into the plug to supply power to the electrical equipment connected to it.

[0050] Especially Figure 9 , 11 As shown in Figure 13, the socket mechanism 3000; 4000 includes an insulating base 30; 40 having side walls and a bottom wall 31; 41, the side walls defining an access opening 35; 45 at the front, the access opening being intended to be closed by a decorative panel 8, and the inner surface of the bottom wall having a portion intended to receive an electrical connection terminal adapted to establish electrical contact between an electrical conductor originating from an electrical network and a conductive element of an electrical plug inserted into a socket 9 of the decorative panel 8.

[0051] like Figure 9 As clearly shown, and more specifically, the insulating base 30 of the socket mechanism 3000 includes three portions 38, 39 for receiving three electrical connection terminals: two lateral portions 38 intended to receive two female terminals, and a central portion 39 intended to receive a male terminal. The term "female terminal" refers to an electrical connection terminal whose functional portion includes a receiving recess intended to receive the connection pin 51 of an electrical plug 50 (e.g., ...). Figure 4 (As shown). The term "male terminal" refers to an electrical connection terminal whose functional part includes an electrical contact element, such as a ground pin 6 (or a lyre-shaped grounding element according to another embodiment not shown), and is designed to protrude from the socket 9 of the decorative panel 8 so as to be inserted into the recess of the electrical plug 50. The ground pin 6 is typically provided for French / Belgian standard sockets. The lyre-shaped grounding element is provided for German standard sockets (Type F), which are not shown here.

[0052] The insert 9 of the decorative panel 8 opens towards the front and is located at the rear by the bottom wall 7 (see...). Figure 11 and 13 The bottom wall is sealed and has three openings, two of which are for receiving recesses of the female terminal of the access socket mechanism, and the third opening is a reserved channel for the ground pin 6. Figure 11 and 13 In the illustrated embodiment, the decorative panel 8 includes a protective wall 4 that slides within the socket 9 in a piston-like manner and has orifices corresponding to those in the bottom wall 7. When the socket 1 is not in use, the protective wall 4 can close the socket 9.

[0053] In a conventional manner, an electrical conductor originating from the electrical network is positioned to protrude from the bottom of the electrical housing 5, below the insulating base of the receptacle mechanism attached to the housing. This electrical conductor travels within a sheath that enters the electrical housing via a sheath inlet. The electrical conductor is then pulled out of the sheath, thereby connecting to the terminals of the receptacle mechanism via the inlet (or insertion opening). Figure 10 As clearly shown, the insertion opening is located in the bottom wall 31 of the insulating base 30 and is defined by corresponding edges 33, 34, 36, and 37. Given that the mechanism includes three electrical connection terminals, it is configured here to connect to three electrical conductors: the live conductor, the neutral conductor, and the ground conductor.

[0054] As will be seen from the following description, the socket mechanism advantageously integrates a female terminal whose profile optimizes the profile of the bottom wall of the insulating base, thereby freeing up space next to the entrance of the electrical conductor to accommodate the natural curvature of the conductor whose ends are sealed within the female terminal. This space facilitates a "wiring" operation, in which the electrical conductor can be connected to a terminal according to the insertion direction applied by the mechanism's terminals. In effect, this space accommodates the natural curvature of the electrical conductor without compression, which arises between the end of the conductor inserted into the terminal and the remaining length of the conductor stored at the bottom of the electrical housing.

[0055] It should be noted that Figure 11 The outline of the insulating base 30 of the socket mechanism 3000 is consistent with... Figure 13The insulating base 40 of the socket mechanism 4000 has a different profile because the profile of each insulating base 30; 40 is adapted to the profile of the female terminal it includes. The insulating base of the socket mechanism according to the invention can also have other profiles depending on the profile of the female terminal it includes, and thus obtain multiple variations of the socket 1 according to the invention.

[0056] In the following description, we will first give a detailed account of the female terminal according to the invention, and then describe the insulating base of the socket mechanism according to the invention in which it is integrated, as well as the male terminal that can be integrated into such an insulating base.

[0057] By convention, in the following description, the terms "front" and "rear" are used relative to the user's line of sight when viewing the socket 1 in its usage position on any receiving wall. Therefore, the term "front" refers to the side of the socket facing the user, and the term "rear" refers to the side of the socket facing away from the user, that is, the side facing inwards towards the receiving wall.

[0058] exist Figures 1 to 7 In figures 12, 13, and 14, five embodiments 100; 200; 300; 400; 600 of the female terminal according to the invention are shown more clearly. The female terminals 100; 200; 300; 400; 600 are shown individually in these figures or as being installed in insulating bases 10; 20; 30; 40; 600 of the first, second, third, fourth, or fifth embodiment of the socket mechanism 1000; 2000; 3000; 4000; 6000, the shape of which is particularly adapted to the shape of the female terminal it receives.

[0059] Regardless of the embodiment of the female terminal 100; 200; 300; 400; 600, it includes a conductive element that defines a first insertion portion 110; 210; 310; 410; 610, which is intended to receive the connection pin 51 of the electrical plug 50 (e.g., Figure 4 (as shown), to establish electrical contact between the connecting pin 51 and the conductive element; the conductive element, on the other hand, defines a second insertion portion 122; 222; 322; 422; 622, which is different from the first insertion portion 110; 210; 310; 410; 610, and is intended to receive an electrical conductor 2 (such as...) from the electrical network. Figure 2 (as shown), to establish electrical contact between electrical conductor 2 and conductive element.

[0060] In other words, the first insertion portions 110; 210; 310; 410; 610 are the portions where electrical contact is established between the connecting pins 51 of the electrical plug 50 and the conductive element, and correspond to the "receiving recesses" 110; 210; 310; 410; 610 of the female terminal. The second insertion portions 122; 222; 322; 422; 622 are the portions where electrical contact is established between the stripped core of the electrical conductor 2 originating from the electrical network and the conductive element. These second insertion portions form electrical cavities 122; 222; 322; 422; 622 for the electrical conductor 2.

[0061] First and second insertion portions 110; 210; 310; 410; 610, 122; 222; 322; 422; 622 are formed in two different parts of the conductive element. These two different parts are electrically connected together: their formation includes a functional portion of receiving recesses 110; 210; 310; 410; 610 and an electrical connection portion 120; 220; 320; 420; 620 including electrical cavities 122; 222; 322; 422; 622.

[0062] The conductive elements of the female terminals 100; 200; 300; 400; 600 are made of a metallic material with good conductivity, thereby transmitting current from the electrical connection portions 120; 220; 320; 420; 620 to the receiving recesses 110; 210; 310; 410; 610.

[0063] For example, the conductive element of the terminal is made of copper or a copper-containing metal alloy—especially brass or bronze.

[0064] The first, second, third and fourth embodiments (see Figure 1 , 3 In (5 and 12), the conductive element is made from a single component formed by folding metal strips 115; 215; 315; 415.

[0065] In the fifth embodiment (see...) Figure 14 In this process, the conductive element is formed by multiple components that are mechanically or electrically connected together: here, one component ends with a second connecting pin 642 that is forcibly inserted into a second recess 640 provided on another component.

[0066] like Figure 2 , 3 As shown in 7, 12 and 14, in all the illustrated embodiments, the receiving recesses 110; 210; 310; 410; 610 can be accessed from the first surface of the female terminal—that is, the front surface—via an inlet mouth defined by the free edges 111; 211; 311; 411; 611 of the conductive element.

[0067] like Figure 2 , 4 As shown in 7, 13, and 14, the receiving recesses 110, 210, 310, 410, and 610 are generally cylindrical and extend from front to back along the axis X passing through the female terminal. According to Figure 2 , 3 In the first, second, fourth, and fifth embodiments shown in 12 and 14, the receiving recess is defined between two branches 116, 216, 416, and 616 of a clamp (gripper) 117, 217, 417, and 617 hinged together around axis C1 (parallel to axis X). The connecting pins of the electrical plug 50 are inserted through the inlet mouth into the two branches along an insertion direction parallel to (or even coinciding with) axis X and clamped. The clamps 117, 217, 417, and 617 are formed by cutting and folding metal strips 115, 215, 415, and 615. Figure 5 In the third embodiment shown, the receiving recess 310 is defined between two branches 316 of a U-shaped clamp 317 hinged together around an axis C2 (perpendicular to axis X). The connector pins of the electrical plug are inserted between these two branches through the inlet opening in an insertion direction coinciding with axis X and are clamped. The U-shaped clamp 317 is formed by cutting and folding a metal strip 315. The clamp 317 is reinforced by a U-shaped component 318—also called a "saddle nail 318"—riveted thereto. The saddle nail 318 tightly surrounds the clamp 317, thereby ensuring that the clamping force of the branches 316 remains constant, even after the connector pins of the plug have been repeatedly inserted and withdrawn from the receiving recess 310.

[0068] Electrical cavities 122; 222; 322; 422; 622 can be accessed from the second surface—here, the rear surface—of the female terminal facing away from the first surface via access openings defined by edges 125; 225; 325; 425; 625.

[0069] In fact, such as Figure 2 , 4As shown in 7, 13, and 14, the female terminals 100; 200; 300; 400; 600 abut against the bottom wall 11; 21; 31; 41; 61 of the insulating base 10; 2000; 3000; 4000; 6000 of the socket mechanism 1000; 2000; 3000; 4000; 6000 via their rear surfaces, located at corresponding positions on the bottom wall 11; 21; 31; 41; 61, such that the access opening for accessing its electrical cavity 122; 222; 322; 422; 622 faces the entrance (or insertion opening) provided in the bottom wall 11; 21; 31; 41; 61 of the insulating base 10; 20; 30; 40; 60. The stripped core of the electrical conductor 2 is inserted into the rear surface of the female terminal through the access openings of electrical cavities 122; 222; 322; 422; 622 (the stripped core enters the insulating base from the inlet on the bottom wall) to supply power to the female terminal. Downstream of the access openings, the stripped core of the electrical conductor 2 establishes electrical contact with the conductive element of the female terminal 100; 200; 300; 400; 600 in the electrical cavities 122; 222; 322; 422; 622. The conductive element transfers electrical energy from the front surface of the female terminal to the connection pin 51 of the inserted electrical plug 50 through the inlet nozzle of the receiving recess 110; 210; 310; 410; 610.

[0070] like Figure 2 , 4 As shown in 7, 13, and 14, a first plane P1 is defined in the female terminals 100, 200, 300, 400, and 600 according to the invention. This first plane includes edges 111, 211, 311, 411, and 611 that define the entrance opening of the receiving recesses 110, 210, 310, 410, and 610, and extends perpendicular to the extending axis X of the receiving recesses 110, 210, 310, 410, and 610. Meanwhile, a second plane P2 is defined in the female terminals 100, 200, 300, 400, and 600 according to the invention. This second plane is parallel to the first plane P1 and includes all or part of the edges 125, 225, 325, 425, and 625 that define the proximal opening of the electrical cavities 122, 222, 322, 422, and 622.

[0071] It is worth noting that, in any embodiment, the first and second planes P1 and P2 are separated from each other by a distance D1 less than or equal to 9 mm. In the first, second, third, and fifth embodiments, the first and second planes P1 and P2 are, for example, separated from each other by a distance between 5 mm and 8 mm. Of course, the distance D1 less than or equal to 9 mm can be any other value. In the fourth embodiment, the first and second planes P1 and P2 are separated from each other by a negative distance D1, that is, the second plane P2 is located in front of the first plane P1 (see...). Figure 13The distance is always measured from plane P1 (see the direction of the arrow indicating distance D1). In a variation of the fourth embodiment, it is entirely conceivable that the distance D1 separating the first and second planes P1 and P2 is zero, i.e., the first and second planes P1 and P2 coincide with each other.

[0072] The second plane P2 is offset towards the front of the female terminals 100; 200; 300; 400; 600, releasing space at the rear surface of the female terminals 100; 200; 300; 400; 600.

[0073] like Figure 2 , 7 As shown in Figures 1 and 12, in the first, third, and fifth embodiments, the second plane P2 is offset forward in the direction of the first plane P1, such that the second plane P2 is offset forward relative to the rear end 112, 312, 612 of the inlet mouth relative to the receiving recesses 110, 310, 610.

[0074] like Figure 3 and 4 As shown, in the second embodiment of the female terminal 200, the second plane P2 is offset forward in the direction of the first plane P1, such that the female electrical connection terminal 200 has a reduced overall height, which is between 5 mm and 9 mm, preferably between 5 mm and 8 mm. According to this embodiment, facing the inlet of the receiving recess 210, the female terminal 200 includes an outlet opening of the receiving recess 210 on its rear surface. The edge 212 defining the outlet opening of the receiving recess is included in the second plane P2. Figure 4 As shown, the standard connection pins 51 of the electrical plug 50 inserted into the female terminal 200 are thus adapted to pass through the receiving recess 210, protrude from the outlet opening, and extend rearward beyond the female terminal 200.

[0075] like Figure 12 and 13 As shown, in the fourth embodiment of the female terminal 400, the second plane P2 is located in front of the first plane P1, such that the second plane P2 is offset forward relative to the inlet opening of the receiving recess 410. This offset creates more space on the rear surface side of the female terminal 400, even though the electrical cavity 433 is laterally moved away from the central extension axis X of the receiving recess 410. Therefore, positioning the second plane P2 in front of the first plane P1 frees up more space on the rear surface of the female terminal 400 and increases the lateral volume of the female terminal 400.

[0076] In either embodiment, the stripped core of electrical conductor 2 is accessed via a proximity opening along the insertion direction Y (see...). Figure 2 , 47, 13, and 14) The electrical cavities 122, 222, 322, 422, and 622 of the female terminal are inserted in an insertion direction Y that may be inclined at an angle S of less than or equal to 45° relative to the axis H that is perpendicular to the second plane P2 and passes through the center of the opening. In other words, the direction Y of the stripped core of the electrical conductor inserted into the electrical cavity 122, 222, 322, 422, and 622 of the terminal is not necessarily completely parallel to the direction X of the receiving recess 110, 210, 310, 410, and 610 of the connection pin 51 of the electrical plug 50; it may be inclined at an angle relative to the insertion direction X, such as 35° or even 45°.

[0077] This arrangement facilitates electrical connections for the female terminals 100; 200; 300; 400; 600, including in connection conditions where the electrical conductors are relatively short and there is insufficient operating space. In practice, the stripped core of the electrical conductor can thus be inserted into the electrical cavities 122; 222; 322; 422; 622 at a small angle S relative to the extension axis X of the recess, and this tilt does not impair the electrical connection of the female terminals 100; 200; 300; 400; 600.

[0078] In a conventional manner, to hold the stripped core of the electrical conductor 2 within the electrical cavities 122, 222, 322, 422, and 622 of the female terminals 100, 200, 300, 400, and 600, and to ensure a good electrical connection between the conductive elements of the female terminals 100, 200, 300, 400, and 600 and the electrical conductor, the female terminals 100, 200, 300, 400, and 600 include clamping (locking, securing) devices for abutting the stripped core against the conductive walls 121, 221, 321, 421, and 621 (see...) Figure 2 , 4 Clamped together, the conductive wall partially defines the electrical cavity 122; 222; 322; 422; 622 of the connection portion 120; 220; 320; 420; 620 of the female terminal.

[0079] Here, as Figure 4 , 5As shown in Figures 12 and 14, the female terminals are shown as self-tightening terminals, and the clamping device for each female terminal is formed by spring plates (not shown in the first embodiment) 230; 330; 430; 630, which continuously apply pressure in the direction of the conductive walls 121; 221; 321; 421; 621. When the stripped core of the electrical conductor 2 is inserted into the electrical cavity 122; 222; 322; 422; 622 via the access opening, it is automatically positioned between the spring plates 230; 330; 430; 630 and the conductive walls 121; 221; 321; 421; 621, which thus clamp the stripped core against the conductive walls 121; 221; 321; 421; 621.

[0080] Spring sheets 230; 330; 430; 630 are made of a metallic material, which may be different from the material of the conductive element of the female terminals 100; 200; 300; 400; 600.

[0081] Disconnection push plates 150; 250; 350; 450 are mounted on the conductive elements of the female terminals. Figure 14 (Not visible in the fifth embodiment of the female terminal 600 shown), thereby enabling the electrical conductors inserted into the electrical cavities 122; 222; 322; 422; 622 to disconnect. The disconnecting push plate 150; 250; 350; 450 is made of an insulating material, such as plastic. When activated by a user or installer, it applies a disconnecting force (the force used to break the connection) to overcome the pressure exerted by the spring tabs 230; 330; 430; 630. This disconnecting force causes the spring tabs 230; 330; 430; 630 to move away from the conductive walls 121; 221; 321; 421; 621, thereby releasing the stripped core of the electrical conductor from the pressure exerted by the spring tabs 230; 330; 430; 630. Therefore, the stripped core can be pulled out of the electrical cavity into which it is inserted via the access opening of the electrical cavity 122; 222; 322; 422; 622, thereby disconnecting the electrical connection of the female terminals 100; 200; 300; 400; 600.

[0082] Advantageously, in any embodiment, the conductive elements of the female terminals 100; 200; 300; 400; 600 define a third insertion portion 123; 323 (not visible in the second, fourth, and fifth embodiments), which is intended to receive a bridging electrical conductor, thereby establishing an electrical contact between the bridging electrical conductor and the conductive element of the female terminal (see...). Figure 1 and 5The third insertion portion forms a second electrical cavity 123; 323 similar to the first electrical cavities 122; 222; 322; 422; 622 described above. This second electrical cavity 123; 323 can be accessed from the rear surface of the female terminals 100; 200; 300; 400; 600 via a second access opening different from the access opening of the first electrical cavities 122; 222; 322; 422; 622, and the second electrical cavity is defined by edges 126; 326 (not visible in the second, fourth, and fifth embodiments). All or part of the edges 126; 326 defining the second access opening are included in the second plane P2, just like the edges 125; 225; 325; 425; 625 defining the first electrical cavities 122; 222; 322; 422; 622.

[0083] Similar to the arrangement in the first electrical cavities 122; 222; 322; 422; 622, the stripped core of the bridging electrical conductor is clamped against a conductive wall that defines the second electrical cavity 123; 323 by a spring sheet similar to the spring sheet used in the first electrical cavity.

[0084] As already described, the different embodiments of the female terminals 100; 200; 300; 400; 600 shown herein according to the invention differ in their respective receiving recesses 110; 210; 310; 410; 610, but also in the shape of their electrical connection portions 120; 220; 320; 420; 620.

[0085] According to the first embodiment (see...) Figure 1 and 2 The electrical connection portion 120 of the female terminal 100 includes two conduits, which are generally cylindrical and have parallel axes. These two conduits form first and second electrical cavities 122, 123 into which stripped cores of electrical conductors (main conductor and bridging conductor) can be inserted. These conduits are defined by cut, bent, and folded portions of a metal strip 115. Each bent portion of the metal strip 115 forms a conductive wall 121, into which the stripped cores inserted into the electrical cavities 122, 123 abut against the conductive wall and are clamped by spring clips. The rear free edges 125, 126 of the metal strip 115 are thus bent and define the proximity openings of the electrical cavities 122, 123 at each conduit. Figure 1 As shown, each electrical cavity 122, 123 is also enclosed at the front by a wall 124, thereby preventing access to the electrical cavity 122, 123 from the front of the female terminal 100. Finally, an opening 128 is provided in the flat portion of the metal strip 115 for securing the spring sheet. The spring sheet can be formed, for example, from a metal strip folded to form a curved portion that ensures the function of the spring. This spring sheet is similar to... Figure 4The spring sheet 230 of the second embodiment of the female terminal 200 is similar to that of the visible female terminal 200.

[0086] exist Figure 3 and 4 In the second embodiment of the female terminal 200 shown according to the invention, the electrical connection portion 220 is similar in all respects to the electrical connection portion 120 of the female terminal 100 according to the first embodiment, except that the electrical connection portion 220 is lower in height and is laterally aligned with the receiving recess 210.

[0087] exist Figures 5 to 7 In the third embodiment shown, the electrical connection portion 320 of the female terminal 300 is formed by a metal strip extending from the bottom of a U-shaped clamp 317, the branches 316 of which define the receiving recess 310. The metal strip has a portion 327 inclined relative to the extending axis X of the receiving recess 310 from its point of connection with the clamp 317, followed by a first raised portion 328, the concave surface of which faces the opening of the receiving recess 310 (i.e., towards the interior of the female terminal 300), and provides proximity openings therein for first and second electrical cavities 322, 323. Downstream of the first raised portion 328, the metal strip extends substantially parallel to the extending axis X of the receiving recess 310, then forms a second raised portion 324, the concave surface of which faces away from the receiving recess 310 (i.e., towards the exterior of the female terminal 300). Therefore, each of the first and second electrical cavities 322, 323 is defined by a first raised portion 328, a second raised portion 324, and a portion of the metal strip extending between the first and second raised portions 328, 324. At least one electrical contact is established between the stripped core of the electrical conductor inserted through the near-opening and the metal strip by abutting against the second raised portion 324. This electrical contact is achieved by means of a spring tab 330. The spring tab 330 abuts against an electrical connection portion 320 of the metal strip, which extends longitudinally through a portion 327 connected to a functional portion including a receiving recess 310, and perpendicular to the portion of the metal strip located between the first raised portion 328 and the second raised portion 324 (see...). Figure 7 The stripped core of the electrical conductor is inserted into one of the electrical cavities 322 and 323 via a corresponding access opening, abutting against the second raised portion 324 of the metal strip, and clamped by a spring plate 330. The second raised portion 324 forms the aforementioned conductive wall 321. The metal strip also includes a device for connecting the spring plate 330 to the metal strip. This device is formed here by a folded claw 331, to which the spring plate 330 can be riveted, for example. The device can also be in the form of teeth, with the corresponding opening of the spring plate fixed around the teeth.

[0088] exist Figure 12 and13 In the fourth embodiment of the female terminal 400 shown, the electrical connection portion 420 is similar in all respects to the electrical connection portion 320 of the female terminal 300 according to the third embodiment, except that the conductive element portion defining the receiving recess 410 and the conductive element portions formed outside the forming portion 427—the raised portions 428, 424—are connected to each other by an extension portion 440. The extension portion 440 forms a single component with the portions forming the conductive elements of the receiving recess 410 and the electrical connection portion 420, respectively. The extension portion 440 extends perpendicular to the extension axis X of the receiving recess 410, generally at the midpoint height of the receiving recess 410, or even as... Figure 13 As clearly shown, it extends at a selected height, thus getting closer to the inlet mouth of the receiving recess 410 than the rear end 412 of the receiving recess 410. As Figure 12 As shown, the elongated portion 440 is also laterally bent to minimize the distance separating the electrical cavity 422 from the receiving recess 410, thereby reducing the lateral volume of the female terminal 400.

[0089] In the third and fourth embodiments of the female terminals 300 and 400, the conductive element including the functional portion forming the receiving recess 310 and 410 and the electrical connection portion 320 and 420 is an integral component.

[0090] exist Figure 14 In the fifth embodiment of the female terminal 600 shown, the receiving recess 610 is formed by a first component of a conductive element, and the electrical connection portion 620 is formed by a second component of a conductive element, which is separate from the first component. The electrical connection portion 620 is similar in all respects to the electrical connection portion 320 of the female terminal 300 according to the third embodiment, except that a metal strip terminates outside the second raised portion 624 at the second connection recess 640. The second recess 640 is designed to receive a second pin 642 by a non-removable, forced engagement, the second pin 642 being carried by a component of the conductive element formed therein in the receiving recess 610.

[0091] Five embodiments of the socket mechanism 1000; 2000; 3000; 4000; 6000 according to the invention include an insulating base 10; 20; 30; 40; 60, which contains the female terminals 100; 200; 300; 400; 600 just described in detail. The female terminals are very similar, and the main difference between them lies in their respective bottom walls 11; 21; 31; 41; 61.

[0092] like Figure 2 , 4As shown in 7, 13, and 14, the bottom walls 11, 21, 31, 41, and 61 of the insulating bases 10, 20, 30, 40, and 60 extend at least at the electrical connection portions 120, 220, 320, 420, and 620 of the terminals, and generally extend along the rear surface of the female terminals 100, 200, 300, 400, and 600 received by the insulating bases 10, 20, 30, 40, and 60.

[0093] Regardless of the shape of the bottom walls 11, 21, 31, 41, and 61 of the insulating bases 10, 20, 30, 40, and 60, the entrances or insertion openings defined by the edges 13, 23, 33, 43, and 63 are arranged in the bottom walls 11, 21, 31, 41, and 61 of the insulating base, next to the openings of the electrical cavities 122, 222, 322, 422, and 622 of the corresponding female terminals 100, 200, 300, 400, and 600, so that the stripped core of the electrical conductor 2 can pass through the insulating bases 10, 20, 30, 40, and 60 and be inserted into the electrical cavity.

[0094] like Figure 2 , 4 As shown in 7, 13 and 14, the edges 13, 23, 33, 43, and 63 that define the insertion opening on one side of the outer surface of the insulating base 10, 20, 30, 40, and 60 are at least partially included in a third plane P3, which is parallel to the second plane P2 and is separated from the second plane P2 by the thickness of the bottom wall 11, 21, 31, 41, and 61 where the insertion opening is located.

[0095] More specifically, such as Figure 4 , 7 As shown in 13 and 16, in the second, third, and fourth embodiments of the socket mechanisms 2000; 3000; 4000, the thickness of the bottom wall 21; 31; 41 of the base 20; 30; 40 such that the insertion opening forms a true guide channel 229; 329; 429 to insert the electrical conductor 2 into the electrical cavity 222; 322; 422 of the corresponding female terminal 100; 200; 300; 400. The guide channel 229; 329; 429 facilitates the insertion of the electrical conductor into the female terminal without affecting the natural curvature of the conductor.

[0096] Considering that the ends of the electrical conductor 2 used to supply power to the female terminal are stripped to a standard length according to the cross-section of the electrical conductor, the distance separating the second and third planes P2 and P3—corresponding to the thickness of the bottom wall next to the opening of the electrical cavity accessible to the female terminal—is also standardized to ensure that part of the insulating sheath of the electrical conductor penetrates into the bottom wall (see...). Figure 16 This ensures the electrical safety of installers and protects the stripped core, which is completely housed in the insulating base.

[0097] like Figure 4 , 7 As shown in Figures 13 and 16, the guide conduits 229, 329, and 429 are cylindrical, shaped such that they have a first cross-section on one side of the outer surface of the bottom wall 21, 31, and 41 of the insulating base 20, 30, and 40, and a second cross-section following the first cross-section, smaller than the first cross-section, and on one side of the inner surface of the bottom wall 21, 31, and 41 of the insulating base 20, 30, and 40. The first cross-section is nearly identical to the cross-section of the electrical conductor (insulating sheath and stripped core) used to supply power to the female terminals 200, 300, and 400 (see Figure 1). Figure 16 The second cross-section is almost identical to the cross-section of the conductive core of the electrical conductor (see...). Figure 16 The ends of electrical conductors are theoretically stripped of their standard length according to their cross-section, thus the shape of the guide tubes 229; 329; 429, with two cross-sections, can instruct installers on how to properly insert the electrical conductor into the terminal, because the optimal insertion is achieved when the insulating sheath surrounding the conductive core of the electrical conductor abuts against the second cross-section of the guide tubes 229; 329; 429 (see...). Figure 16 The end of this description shows a variation of the guide pipe.

[0098] Of course, the second entrance or second insertion opening defined by edges 34; 44 (only when...) Figure 9 , 10 (See Figure 11) A second opening is provided in the bottom wall 31; 41 of the insulating base 30; 40, facing the second electrical cavity (also referred to as the bridging electrical cavity) of the female terminal, so that the stripped core of the bridging conductor can be inserted into the second electrical cavity. The second insertion opening has the same characteristics as the first insertion opening. In particular, the edge 34; 44 defining the second insertion opening on one side of the outer surface of the bottom wall 31; 41 of the insulating base 30; 40 is at least partially included in the third plane P3 (see Figure 11). Figure 10 Additionally, the second insertion opening also forms a guide channel for connecting the opening of the bridging electrical cavity that is accessible to the corresponding female terminal.

[0099] As already described, the insulating bases 10; 20; 30; 40; 60 are also designed to receive the male electrical connection terminal 700. Therefore, regardless of which embodiment of the socket mechanism 1000; 2000; 3000; 4000; 6000, but especially as... Figure 10 The third embodiment of the socket mechanism 3000 shown, in addition to the insertion openings provided in the bottom wall 31 of the insulating base 30 for accessing the first electrical cavity 322 and the second electrical cavity 323 (or bridging electrical cavity 323) of each female terminal 300 received by the insulating base 30, also has at least one insertion opening defined by an edge 36 for accessing the electrical cavity 722 of the male terminal 700 (see...). Figure 8 The electrical cavity 722 is designed to receive the conductive core of the ground conductor, thereby grounding the male terminal 700. Similar to the arrangement for the female terminal 300, an insertion opening defined by edge 37 is also provided for accessing the bridging electrical cavity of the male terminal 700.

[0100] Advantageously, and as Figure 10 As is particularly evident in the third embodiment of the socket mechanism 3000 shown, all the edges 33, 34, 36, 37 that define the insertion openings of the insulating base 30 are located in the same third plane P3.

[0101] Regardless of the embodiment of the socket mechanism, the profile of the bottom wall of the insulating base of the mechanism allows for free space next to the insertion opening, and advantageously, this free space facilitates wiring operations of the mechanism. This free space is located within the electrical housing 5, in which the socket mechanism is mounted, with the electrical conductors originating from the electrical network reaching the bottom of the electrical housing 5. Advantageously, this free space accommodates the natural curvature adopted by each electrical conductor after connection to the mechanism, with the bent portion inserted between the free end of the electrical conductor held in its power supply terminal and its remaining length pressed into the bottom of the electrical housing. Thus, after completing the electrical connection of the mechanism, the installer can easily press the remaining length of the electrical conductor into the bottom of the electrical housing, positioning it at the rear of the insulating base, where the electrical conductor can freely adopt its natural curvature within the free space next to the insertion opening on the bottom wall of the base.

[0102] By means of the advantageous shape of the insulating base of the socket mechanism according to the invention, space is freed not only next to the electrical cavity of the female terminal but also next to the electrical cavity of the male terminal, thereby accommodating the natural curvature of all electrical conductors supplying power to the mechanism.

[0103] like Figure 2 , 7As shown in 10, 13, and 14, in the first, third, fourth, and fifth embodiments of the socket mechanism according to the invention, the bottom wall 11, 31, 41, and 61 of the insulating base 10, 30, 40, and 60 includes a misaligned portion 12, 32, 42, and 62 that is offset from the front of the insulating base 10, 30, 40, and 60 in the direction of the receiving opening 15, 35, 45, and 65 enclosed by the decorative panel 8 of the socket. An insertion opening is provided in the misaligned portion 12, 32, 42, 62, and 62, which has an access opening for reaching the electrical cavities 122, 322, 422, 622, and 722 of each female terminal 100, 300, 400, 600, and male terminal 700. By means of the misaligned portions 12; 32; 42; 62, including the third plane P3 that defines all or part of the edges 13; 33, 34, 36, 37; 43, 44; 63 of the insertion opening, the third plane P3 is thus offset by a distance D2 relative to the fourth plane P4, which is parallel to the third plane P3, and includes the bottom wall 11; 31; 41; 61 of the insulating base 10; 30; 40; 60, the farthest (or rearmost) portion of the receiving opening 15; 35; 45; 65 of the insulating base 10; 30; 40; 60 relative to the receiving opening 15; 35; 45; 65 of the insulating base 10; 30; 40; 60 (see...) Figure 2 , 7 (13 and 14). The bent portion of the electrical conductor supplying power to the female terminal is thus accommodated in the free space defined between the misaligned portions 12; 32; 42; 62 and the remainder of the bottom walls 11; 31; 41; 61 of the insulating base 10; 30; 40; 60. In other words, in these embodiments, the bent portion of the electrical conductor is accommodated within the overall volume of the insulating base.

[0104] Here, the distance D2 separating the third and fourth planes P3 and P4 is at least 2 mm, that is, greater than or equal to 2 mm, and preferably at least 5 mm.

[0105] In such Figure 10 In the configuration of the insulating base 30 shown, all insertion openings are disposed in the same third plane P3, offset forward relative to the fourth plane P4, by means of, Figure 8 The special shape of the male terminal 700 according to the present invention can achieve, as shown, the following Figure 10 The configuration shown.

[0106] The male terminal 700 includes a conductive element 701, which, on one hand, is connected to the ground pin 6, and on the other hand, defines an electrical cavity 722 for receiving an electrical conductor, thereby establishing electrical contact between the electrical conductor and the conductive element 701. More specifically, on one hand, the conductive element 701 forms a platform 710 on which the ground pin 6 is pressed and is intended to protrude from the interior space of the insulating base 30 for receiving the decorative panel 8 (see...). Figure 11On the other hand, the conductive element 701 is formed in all respects a metal strip similar to the electrical connection portions 320, 420, and 620 of the female terminals 300, 400, and 600 according to the third, fourth, and sixth embodiments of the female terminals according to the invention. The electrical cavity 722 defined by this metal strip can be accessed from the rear surface of the male terminal 700's back-to-ground pin 6 via an access opening defined by the edge 725 of the conductive element 701. The metal strip also defines a bridging electrical cavity (in... Figure 8 (not visible in the middle), can be transmitted through the edge of conductive element 701 (in the middle). Figure 8 The proximity opening (not visible in the image) is used to establish electrical contact between the bridging electrical conductor and the conductive element 701. The conductive core of the male terminal 700, inserted into the electrical cavity 722 of the corresponding proximity opening or bridging the electrical cavity, is held in position by the automatic clamping of the spring sheet 730. When the male terminal 700 is in place in the insulating base 30, a disconnecting push plate 350 (similar to that described for the female terminal, see image 350) is used. Figure 10 It can act on the spring sheet 730, thereby disconnecting the electrical conductor inserted into the electrical cavity 722.

[0107] like Figure 10 As clearly shown, the electrical cavity 722 and the bridging cavity are offset forward in the direction of the platform 710, and the ground pin 6 is mounted on the platform 710. Therefore, a plane P'2 can be defined in the male terminal 700, which is generally parallel to the platform 710 and includes all or part of the edge 725 that defines the proximal opening of the electrical cavity 722 and all or part of the edge (not visible) that defines the proximal opening of the bridging cavity.

[0108] The bottom wall 31 of the insulating base 30 is designed to accommodate the male terminal 700 such that its plane P'2 is aligned with and coincides with the second plane P2 of the female terminal 300 (see...). Figure 10 Therefore, plane P'2 is parallel to the third plane P3 and is separated from the third plane P3 by the thickness of the bottom wall 31 of the insulating base 30. Thus, when the male terminal 700 is positioned in the insulating base 30, the access opening to its electrical cavity 722 and the access opening to its bridging cavity are respectively positioned facing two insertion openings provided in the bottom wall 31 of the insulating base 30 and defined by edges 36 and 37. Figure 3As shown, the insulating base 20 of the second embodiment of the socket mechanism 2000 is shallow. Therefore, in the insulating base 20, there is no overlap between distance D2 and the third and fourth planes P3 and P4. Therefore, in the second embodiment of the socket mechanism 2000, the overall volume of the insulating base 20 is reduced, thereby freeing up space at the rear of the entire bottom wall 21 of the insulating base 20. A channel opening defined by edge 28 is provided in the bottom wall 21 of the insulating base 20, facing the outlet opening of the receiving recess 210 of the female terminal 200, such that the connecting pins of the electrical plug inserted into the receiving recess 210 pass through the channel opening, thereby extending rearward beyond the bottom wall 21 of the insulating base 20 (see...). Figure 4 ).

[0109] Advantageously, to enhance electrical safety and prevent any access to the exposed portion of the bottom wall 21 of the insulating base 20 of the socket mechanism 2000 towards the connecting prongs of the electrical plug, the channel opening of the bottom wall 21 (defined by the edge 28) is sealed by a thin film 29 made of deformable material (see...). Figure 4 When pressure is applied to the connecting pins 51 of the electrical plug 50 on the thin film 29 made of flexible insulating material, the film can deform but not break (see...). Figure 4 The film 29 is made of a flexible plastic material, and therefore also has electrical insulation properties.

[0110] The present invention is not limited to the embodiments described in the detailed description above, and various other modifications can be made to it.

[0111] Especially according to Figure 15 and 17 The advantageous variant shown has a guide tube formed by the insertion opening in the bottom wall of the insulating base of the socket mechanism, which is more conducive to the electrical conductor being pressed into the rear of the socket mechanism.

[0112] More specifically, such as Figure 15 and 17 As shown, a variation of the insertion opening applied to a third embodiment of the socket mechanism 3000 according to the invention is illustrated, wherein the guide channel 329' is not entirely cylindrical, but has a chamfered portion 329A' that extends obliquely relative to the central extension axis I of the guide channel 329' (see...). Figure 17 The central extending axis I is perpendicular to the portion of the bottom wall 31 of the insulating base 30 that forms the guide conduit 329'. The central extending axis I of the guide conduit is perpendicular to the axis H (see...). Figure 7 The axes H coincide, passing through the center of the opening of the electrical cavity that is accessible to the connection terminal housed at the rear of the insertion opening. The chamfered portion 329A' extends away from the disconnect push plate associated with the insertion opening.

[0113] Here, the chamfered portion 329A' is provided in the first cross-section of the guide conduit 329', which is located on the outer surface of the bottom wall 31 of the insulating base 30. Therefore, the first cross-section of the guide conduit 329' is elliptical, and its dimensions are larger than the cross-sectional dimensions of the electrical conductor 2. Thus, a larger portion of the bent portion 2A of the electrical conductor 2 (see...) can be accommodated in the first cross-section of the guide conduit 329'. Figure 17 ).

[0114] More advantageously, the edge 33' defining the insertion opening forming the guide conduit 329' on one side of the outer surface of the bottom wall 31 of the insulating base 30 extends on two layers 33A', 33B', which are connected together in a stepped manner (see...). Figure 15 ).

[0115] In other words, the edge 33' that defines the insertion opening includes two parts 33A' and 33B' that are offset from each other along the central axis I of the guide tube.

[0116] According to a variation not shown, the two layers 33A', 33B' that define the edge 33' of the insertion opening can be connected sequentially without being interrupted in a stepped manner.

[0117] The guide channel 329' thus constructed has a chamfered portion 329A' and an outer edge 33' extending on two layers 33A', 33B', which can accommodate a large portion of the bent portion 2A of the electrical conductor 2. The volume of the electrical conductor 2 connected to the rear of the socket mechanism is thus reduced, making it easier to insert into the electrical housing designed to accommodate the mechanism.

[0118] Of course, this advantageous configuration of the guide conduit 329' can be applied to any of the above embodiments, and also to any insertion opening that opens in the main or bridging electrical cavity of the male or female electrical connection terminal.

[0119] Furthermore, even though it differs from the present invention, this configuration of the guide pipe is very advantageous because it can save space by partially accommodating the curved portion of the electrical conductor.

[0120] The connecting terminals (male or female) can also be screw terminals, instead of self-tightening terminals (self-tightening by spring tabs).

[0121] The socket can also consist of only two female electrical connection terminals and a lyre-shaped grounding piece (a German-style socket known as "Schuko").

[0122] The socket can also be of the wall-mounted type, secured by an electrical housing that protrudes from the wall.

[0123] Of course, various other modifications can be made to the invention within the scope of the appended claims.
