Description

TECHNICAL FIELD TO WHICH THE INVENTION RELATES The present invention relates to an electrical device comprising, on the one hand, a support plate supporting an electrical circuit printed on at least one of its faces and, on the other hand, at least one electrical connection terminal for the power supply of said printed circuit, which comprises a spring blade. It also relates to an electrical apparatus comprising an electrical socket or an electrical plug and an electrical device of the aforementioned type. The invention finds a particularly advantageous application for the production of electrical equipment, wherein the printed circuit of said electrical device constitutes a remote control circuit of the associated electrical outlet.

BACKGROUND OF THE ART It is already known, in particular from DE102009007561, an electrical device as described in the introduction, comprising an electrical socket on which is welded, on the front face, a printed circuit. This printed circuit comprises two openings adapted to be traversed by two connecting pins of a complementary electrical plug for connecting this plug to the cells of the electrical outlet. One of the openings of the printed circuit comprises a conductive wall, so that the connecting pin of the electrical plug which passes through it comes into contact with this wall.

This pin for connecting the electrical plug is also in contact with a spring blade, housed inside a well of the electrical outlet, and protruding from the inner surface of the socket well. This spring blade is also in electrical contact with the printed circuit. Such an electrical connection is, however, quite unsuitable for the passage of a current of 16 amperes. The coating of the opening of the printed circuit hosting the connection pin of the electrical plug is not particularly adapted to withstand the passage of such a current. The electrical connection between the plug connection pin and the printed circuit board is not sufficiently reliable for the passage of a current of 16 amperes. There are indeed risks of overheating and destruction of the opening of the printed circuit hosting the connection pin of the electrical plug. OBJECT OF THE INVENTION In order to overcome the aforementioned drawback of the state of the art, the present invention proposes an electrical device adapted to supply the printed circuit with a current of 16 amperes. More particularly, the invention proposes an electrical device as defined in the introduction, wherein said electrical connection terminal further comprises a conductive cage, distinct from the spring blade, this cage being provided with at least one leg electrical connection connected electrically to said printed circuit and housing said leaf spring so that it exerts a permanent pressure on at least one inner face of said cage.

Thus, advantageously, thanks to the invention, the electrical connection pin which supplies the electrical circuit, here an intermediate connection element, enters this connection terminal between the inner face of the cage and the leaf spring, so as to be pressed against said inner face of the cage by this leaf spring.

In this way, a satisfactory and robust contact is ensured between the electrical connection pin introduced into the connection terminal and the cage. In addition, the materials forming respectively the cage and the leaf spring from the connection terminal of the device according to the invention may have different characteristics of elasticity and electrical conductivity so as to optimize the electrical connection made. Other non-limiting and advantageous features of the device according to the invention are as follows: said conductive cage extends from one of the faces of said support plate and said electrical connection tab of the conductive cage passes through a orifice of said support plate and emerges projecting from the other face of the support plate; said conductive cage extends from one of the faces of said support plate and said electrical connection tab of the conductive cage is applied against this face of the support plate; said conductive cage extends from one of the faces of said support plate and comprises at least two connection lugs, including an electrical connection lug which is applied against this face of the support plate and another lug of an electrical connection which passes through an orifice of said support plate and protrudes from the other side of the support plate; - The conductive cage and the spring blade are made of two different materials; - The cage is made of a brazeable material and the spring blade is made of a selected material such that said spring blade has a greater elasticity than that of the conductive cage; said electrical connection terminal is disposed facing a through opening of the support plate, so that an intermediate connection element passing through said opening opens out between said inner face of the conductive cage and the blade springing from said connection terminal.

The invention also relates to an electrical apparatus comprising an electrical socket, an electrical device as described above, and at least one intermediate connection element connecting the connection terminal of the electrical device and one of the connection cells of the electrical socket. Advantageously then, the printed circuit of said electrical device constitutes a remote control circuit of the associated electrical outlet. In a variant, the printed circuit of the said electrical device constitutes a circuit for powering a USB socket. The invention finally relates to an electrical apparatus comprising an electrical plug, an electrical device as described above, and at least one intermediate connecting element connecting the connection terminal of the electrical device and one of the connection pins of the electrical plug. .

FIGS. 2, 3, 7, 8, 12, 13, 17, 18, 21 are shown in FIG. , 22, 25, 26, 30, 31, 36 and 37, different embodiments of an electrical device 100; 30,200; 300; 400; 500; 600; 700; 800 according to the invention. This electrical device 100; 200; 300; 400; 500; 600; 700; 800 essentially comprises, on the one hand, a support plate 110; 210; 310; 410; 510; 610; 710; 810 supporting a printed circuit (here not shown) and, secondly, at least one connection terminal 10; 20; 30 ; 40; 50; 60 electrical for the power supply of said printed circuit. The support plate 110; 210; 310; 410; 510; 610; 710; 810 has two opposite planar faces 111, 112; 211, 212; 311, 312; 411, 412; 511, 512; 611, 612; 711, 712; 811, 812 and supports the printed electrical circuit 5 on at least one of its opposite planar faces. In practice, the printed electrical circuit may extend on one or both opposite planar faces of the support plate. This support plate may also comprise two separate printed electrical circuits each extending on one of its opposite planar faces. The printed electrical circuit is not shown in the figures. Conventionally, it consists of at least one thin layer of copper etched by a chemical process to obtain a set of tracks, terminated by pellets. The printed electrical circuit is often covered with a layer of colored varnish that protects the tracks from oxidation and possible short circuits. Different electrical components can be electrically connected to each other by the copper tracks of the printed electrical circuit. Here, the electrical device according to the invention may comprise any type of electrical components which will not be described in detail since they do not form part of the invention. The connection terminal 10; 20; 30 ; 40; 50; 60 comprises a spring blade 1 1; 21; 31; 41; 51; 61. Remarkably, it further comprises a cage 12; 22; 32; 42; 52; 62 conductor, distinct from the leaf spring, which is provided with at least one connecting lug 13; 23A, 23B; 33A, 33B; 43; 53; 63 electrically connected electrically to said printed circuit and housing said spring blade 11; 21; 31; 41; 51; 61 so that it exerts a permanent pressure on at least one inner face of said cage 12; 22; 32; 42; 52; 62 (see FIGS. 4, 5, 9, 14, 19, 23 and 27). In most embodiments of the connection terminal 30 shown in the accompanying figures (first, second, third, fourth, and sixth embodiments shown in FIGS. 1 to 19, 24 to 27, 30 and 37), the blade spring 11; 21; 31; 41; 61 has a bent or bent shape and is at least partially housed in the cage 12; 22; 32; 42; 62 corresponding so that at least one of its free ends is prestressed, bearing against said inner face of the cage. In this way, this free end of the spring blade exerts a permanent pressure on this inner face of the cage. More specifically, in the first, second, third, and fourth embodiments of the connection terminal 10; 20; 30 ; 40 (FIGS. 1 to 19, 29 to 33 and 36 to 39), the cage 12; 22; 32; 42 has the shape of a generally parallelepipedic sleeve with four flat side walls P1, P2, P3, P4 connected by rounded corners (Figures 1, 6, 11 and 16, 32, 37). It is formed by the folding of a flat metal sheet.

The leaf spring 11; 21; 31; 41 is mounted in the sleeve forming the cage 12; 22; 32; 42. In the first and second embodiments shown here, the spring blade 11; 21 has the same shape (Figures 1 to 9). It comprises three branches B1, B2, B3: a main branch B1 central and substantially flat, which is pressed against the inner face of one of the walls P1 of the cage 11; 21. From this main branch B1 extend two lateral branches B2, B3, folded on the same side of the main branch B1 (Figures 1 and 6). The lateral branches B2, B3 are connected by elbows to the main branch B1 of the spring blade.

One of the lateral branches B2 of the leaf spring 11; 21 extends near the support plate 110; 210 of the electrical device 100; 200 corresponding in a straight direction oblique towards the wall P3 of the cage 12; 22 opposite the wall P1 against which is applied the main branch B1 of the spring blade.

The free edge of this lateral branch B2 is curved towards the main branch B1 (FIGS. 1 and 6). Similarly, the other lateral branch B3 of the leaf spring 11; 21 has a bent shape whose free edge is curved towards the main branch B1 of the leaf spring.

This curved shape of the free edge of the lateral branches B2, B3 of the blade spring 11; 21 facilitates the introduction of an intermediate contact element between a wall of the cage of the connection terminal and the lateral branches B2, B3 of the leaf spring placed in the cage. The main branch B1 of the leaf spring 11; 21 further comprises mounting means in the cage 12; 22. This is clipping mounting means comprising BV shutters cut in the main branch B1 and protruding from the main branch B1 on the side opposite the lateral branches B2, B3 (Figures 1 and 6). These BV flaps cooperate to retain with complementary windows FV formed in the wall P1 of the cage 12; 22 against which the main branch B1 of the spring blade is supported (Figures 1 and 6). In the third embodiment of the connection terminal 30, the spring blade 31 has a simplified shape similar to that of the leaf spring of the first and second embodiments, except that the other side leaf B3 is removed. The spring blade 31 then comprises only a main branch B1 and a lateral branch B2 (FIG. 10), the arrangement of which is similar to that of the branches B1 and B2 described above with reference to the first and second embodiments. The mounting means of the spring blade 31 in the cage 32 here comprise a single flap similar to those described above, which cooperates with a window complementary to the cage, and an opening which accommodates a hook CR coming from the wall P1 of the cage 32 against which the main branch B1 of the leaf spring 31 is applied (Figure 10). In the fourth embodiment of the connection terminal 40, the leaf spring 41 has a simplified shape similar to that of the leaf spring of the third embodiment, with a main branch B1 and a side branch B2 (Figure 15). The free edge of the side branch B2 is here right. The lateral branch B2 more particularly comprises a flat part 25 which extends perpendicularly to the main branch B1 of the spring blade 41. This flat part extends against the support plate 410 (FIG. 19), and comprises two Al flanges housed in a complementary slot E of the free edge 42A, located against the support plate, the sleeve forming the cage 42 (Figure 16). The end of the main branch B1 opposite to the lateral branch B2 terminates in its turn by a curved flange which bears on the opposite free edge 42B of the sleeve forming the cage 42 (FIGS. 15 and 16). Thus, here, the spring blade 41 cooperates for its mounting in the cage 42 with the free edges 42A, 42B of the sleeve forming the cage 42 (Figures 15 and 16). The fifth and sixth embodiments of the connection terminal 50; 60 shown in Figures 20 to 27 have a structure slightly different from those of the embodiments described above. The cage 52; The conductor of the connection terminal is here formed by a U-shaped bent metal plate, so as to define two main walls 52A, 52B; 62A, 62B parallel facing and an end wall 52C; 62C connecting the two main walls 52A, 52B; 62A, 62B (Figures 20 and 24). In the fifth embodiment of the connection terminal 50 shown in Figures 20 to 23, the spring blade 51 is bent in an arc.

It is threaded on a first main wall 52A of the cage 52, so that a central portion 51A (Figure 20) of the spring blade 51, corresponding to the top of the curve described by this leaf spring 51 between its two free ends, is applied against the second main wall 52B opposite the first of the cage 52, so as to be prestressed against this second wall 52B (Figure 20). In this way, the central portion 51A of the leaf spring 51 permanently exerts a pressure on the inner face of the second main wall 52B of the cage 52. More specifically, each of the two free ends of this spring blade 51 comprises an opening passing through the first main wall 52A of the cage 52 of the connection terminal 50. These two passage openings constitute the means for mounting the spring blade 51 on the cage 52. In the sixth embodiment of the connection terminal 60 shown in Figures 24 to 27, the spring blade 61 is constituted by a wafer, a central portion 61 B is partially cut and bent. The peripheral portion 61A of the wafer forms a frame that extends perpendicularly to the longitudinal axis of the cage 62, around the cage 62, so that the central portion 61 B curved of the wafer extends between the opposite main walls 62A, 62B of said cage 62. The free edge of the curved central portion 61 B is pressed against one of the main walls 62B (Figure 24) of the cage 62. It is curved towards the inside of the cage 62 to facilitate the introduction of an intermediate contact element into the corresponding connection terminal, between the central portion 61 B of the spring blade and the main wall 62B of the cage 62.

Whatever the embodiment of the connection terminal, one of the walls of the cage 12; 22; 32; 42; 52; 62 of the connection terminal 10; 20; 30 ; 40; 50; 60 is extended by at least one connecting lug 13; 23A, 23B; 33A, 33B; 43; 53; 63 (Figures 1, 6, 11, 16, 20, 24, 29, 30, 36 and 37).

In practice, a plurality of connection tabs are provided. These connection tabs 13; 23A, 23B; 33A, 33B; 43; 53; 63 have a dual function: they ensure, on the one hand, the electrical connection of the conductive cage 12; 22; 32; 42; 52; 62 of the corresponding connection terminal with the printed circuit carried by the support plate 110; 210; 310; 410; 510; 610; 710; 810, and on the other hand, the mechanical holding of this connection terminal on this support plate. To ensure this electrical connection and mechanical holding, at least one connecting lug 13; 23A, 23B; 33A, 33B; 43; 53; 63 of each connection terminal is brazed to the printed electrical circuit of the support plate 110; 210; 310; 410; 510; 610; 710; 810. Two types of connector leads are considered here. A first type of connection lugs, hereinafter referred to as connection tabs, is present in all the embodiments shown. These are, for example, connection tabs 13; 23A; 33A; 43; 53; 63 of the conductive cage of the first, second, third and fourth embodiments of the connection terminal (Figures 1, 6, 11, 16, 20, 24, 31, 36). Each through connection tab 13; 23A; 33A; 43; 53; 63,711; 811 of said faces of said support plate and said electrical connection tab emerges from the other face 112; 212; 312; 412; 712; 812 of the support plate (Figures 1, 6, 11, 16, 20, 24, 31, 36).

Each through connection tab 13; 23A; 33A; 43 is in the form of a tongue which extends from the free edge of the cage 12; 22; 32; 42, in the extension of the corresponding wall of the cage, that is to say parallel to the longitudinal axis of this cage. This longitudinal axis corresponds to the longitudinal axis of the sleeve forming the cages of the first, through a corresponding orifice of the support plate 110; 210; 310; 410,510; 610; 710; 810, so that the cage 12; 22; 32; 42; The conductor extends from a first 111; 211; 311; 411; 511; 611; second, third and fourth embodiments. Alternatively, as in the case of the fifth and sixth embodiments, some through-plugs 53; 63 (Figures 20 and 24) are bent: they extend in a profile staircase from the free edge of the cage 52; 62 oriented towards the support plate, towards the outside of this cage 52; 62. The free end of this through connection tab 13; 23A; 33A; 43; 53; 63 may be straight (FIGS. 15, 16, 20, 24) or have beveled corners (FIGS. 1, 6, 11) to facilitate its insertion through the corresponding orifice of the support plate. Through-connecting lugs 13; 23A; 33A; 43; 53; 63 of the terminal allow an effective mechanical maintenance of the connection terminal on the support plate and the power of the printed electrical circuit carried by the other face 112; 212; 312; 412; 512; 612; 712; 812 of the support plate.

For this purpose, each through connection tab is fixed and / or electrically connected to this other face of the support plate, for example by gluing or brazing. They are preferably brazed to the printed electrical circuit carried by this other face of the support plate. Some of the embodiments of the connection terminal proposed herein further include a second type of connector lugs, hereafter referred to as non-through connector lugs 23B; 33B (FIGS. 6 to 14, 30, 32, 37 and 39). Each non-through electrical connection tab 23B; 33B of the conductive cage is applied against the first face 211; 311; 711; 811 of the support plate 210; 310; 710; 810. The non-through connection tabs of the connection terminal reinforce the mechanical holding of the connection terminal on the support plate and allow the power supply of the printed electrical circuit carried by said first face 211; 311; 711; 811 of the support plate. For this purpose, each non-through connection tab is fixed and / or electrically connected to this first face of the support plate, for example by gluing or brazing. They are preferably brazed to the printed electrical circuit carried by this first face of the support plate. Advantageously, because the cage 12; 22; 32; 42; 52; 62 and the leaf spring 11; 21; 31; 41; 51; 61 of the connection terminal 10; 20; 30 ; 40; 50; 60 consist of two separate pieces assembled, it is possible to make these two pieces in two different materials. It is then advantageously possible to optimize the qualities of the two chosen materials so that each of these two pieces performs the function devolved to it at best. In particular, the cage 12; 22; 32; 42; 52; 62 is preferably made of a brazeable material. It is furthermore obviously made of a material having a maximum electrical conductivity. This is for example brass, especially one of the alloys having the composition whose ISO designation is CuZn15 or CuZn36. The leaf spring 11; 21; 31; 41; 51; 61 is made of a material having elastic qualities ensuring that the pressure exerted by the blade 15 spring on the cage is optimal. This is to exert a maximum pressure while allowing the introduction of an intermediate element of electrical connection between the spring blade and the cage. The material of the spring blade is chosen so that it has a greater elasticity than that of the conductive cage. This is in particular a non-brazeable material. This is particularly a stainless steel. It may also be a non-conductive material, for example a plastic. In the electrical device 100; 200; 300; 400; 500; 600; 700; 800 according to the invention, said connection terminal 10; 20; 30 ; 40; 50; 60 electrical is disposed opposite an opening 113; 213; 313 - 413; 513; 613; 713; 813 through the support plate 110; 210; 310,410; 510; 610; 710; 810 (Figures 3, 8, 13, 18, 22, 26, 29, 31, 36 and 38), so that an intermediate connecting member 120; 220; 320; 420; 520; 620; 720; 820 (FIGS. 3, 4, 5, 8, 9, 12, 13, 14, 17, 18, 19, 22, 23, 26, 27, 29 to 33, 36 to 39) passing through this opening opens between the spring blade 11; 21; 31; 41; 51; 61 of said connection terminal and said inner face of the cage 12; 22; 32; 42; 52; 62 against which the spring blade is supported. The intermediate connection element 120; 220; 320; 420; 520; 620; 720; 820 preferably consists of a connection blade. This intermediate connection element 120; 220; 320; 420; 520; 620 allows the electrical connection of the connection terminal 10; 20; 30 ; 40; 50; 60 fixed on the support plate 110; 210; 310; 410; 510; 610; 710; 810 to a power supply. Two examples of intermediate connection elements 720; 820 will be more particularly described later. Indeed, the invention also relates to electrical equipment comprising an electrical device as described above. Two examples of electrical equipment 1000; 2000 are shown in Figures 28 to 39.

This is more particularly electrical equipment 1000; 2000 including an electrical outlet 1100; 2100 and at least said intermediate connecting element 720; 820 of an electrical device 700; 800. This intermediate connection element 720; 820 makes it possible to connect the connection terminal 30 of the electrical device 700; 800 and one of the connection cells of the electrical outlet 1100; 2100. The connection terminal 30 of these two electrical devices 1000; 2000 is here according to the third embodiment of the connection terminal described above. However, each of these two electrical devices can be realized with any of the other embodiments of the connection terminal described above. More specifically, in the first example of electrical equipment shown in Figures 28 to 33, the printed circuit of the electrical device 700 of the electrical equipment 1100 is a power supply circuit of two USB sockets 1600.

The electrical apparatus 1000 comprises an insulating casing 1400 (FIGS. 32 and 33), which is connected to an insulating frame 1300 (FIGS. 28, 29, 32 and 33) accommodating the electrical switchgear mechanism 1500 and the electrical device 700. This frame 1300 has a generally parallelepiped shape and comprises four side walls 1310 and a front wall 1320 which covers the support plate 710 of the printed circuit. This front wall 1320 has passage openings, on the one hand, the appliance mechanism 1500 of the electrical outlet and, on the other hand, the cells 1620 for connecting the two USB sockets 1600 (FIGS. 32, 33).

The frame 1300 further comprises a rear wall 1330 which extends only facing the fitting mechanism of the electrical outlet 1500 and forms a housing therefor (Figure 33). The casing 1400 also has a generally parallelepipedal shape, open at the front.
