According to the invention, the frame incorporates, at two different places, bending means (150) adapted to bend an insulated electric wire immobilized against the frame, at two different places of said insulated electric wire, these two places being spaced apart by a distance (d) between the internal and external widths of said frame.

Description

Technical field to which the invention relates

The present invention relates generally to the supports used to attach any switchgear mechanism, such as for example a switch or socket outlet mechanism, in a box to be embedded in any wall or in a housing to bring back from such a wall.

It relates more particularly to an electrical apparatus support comprising a frame having an external width taken between two opposite sides of an outer peripheral edge of said frame and an internal width taken between two opposite sides of an inner peripheral edge of said frame.

In the support according to the invention, the inner peripheral edge of the frame can delimit a central opening through which an insulating base containing the electrical elements of the fitting mechanism is attached, or it can delimit an access opening to the interior space of a base forming a single piece integrally with the frame. In the latter case, the frame forms a ledge or a sidewalk bordering the base.

Technological background

Currently to carry out an electrical transplanting between two devices mounted side by side in the same box, using pliers, the installer cuts and bends the insulated electrical transplanting wires to the desired length so that each of the stripped ends of these electrical wires can be engaged and connected in the corresponding electrical terminals of two devices.

The installation of the correct length of each transplanting wire is done "by eye" by the installer, who has previously measured the distance between the entries in the housings of similar transplanting terminals of the two devices associated via the assembly of their supports.

This lengthening by bending is carried out using pliers to produce curvatures of wire with a small radius.

It is a long and often tedious operation which requires the installer a certain hand.

Object of the invention

Compared to the above-mentioned state of the art, the present invention provides a new apparatus support which also forms a template for forming an electrical transplanting wire.

More particularly, according to the invention, an electrical equipment support is proposed comprising a frame having an external width taken between two opposite sides of an outer peripheral edge of said frame and an internal width taken between two opposite sides of a peripheral edge interior of said frame, characterized in that the frame incorporates, at two different places, bending means adapted to bend an insulated electric wire immobilized against the frame, at two different places of said insulated electric wire, these two places being spaced apart distance between the internal and external widths of said frame.

Thus, advantageously, the support according to the invention, the width of which generally corresponds to the standardized distance between centers of the inputs of the electrical terminals of the two associated electrical devices, itself serves as a tool for bending each insulated electrical wire of transplanting to the right length, without wasting time.

By positioning each electric wire along this width in said means of curvature of said support, the installer can easily and quickly bend each electric wire into a U to the right length, without using pliers and without carrying out a preliminary center-to-center measurement operation.

Other non-limiting and advantageous characteristics of the support for electrical equipment according to the invention, taken individually or in any technically possible combination, are the following:

- The frame has a generally rectangular shape with an external width, said curvature means being arranged on the frame to form on the insulated electric wire immobilized against the frame, two distant curvatures of a length substantially equal to said external width of the frame;

- It has, on each of said two opposite sides of its outer peripheral edge, means of assembly to another support of the same type, said curvature means being distinct from these assembly means;

- It comprises on the two other opposite sides of its outer peripheral edge, assembly means identical to said assembly means carried by said first opposite sides;

- The assembly means comprise on each side of the outer peripheral edge, at least one pair of lugs and notches of complementary shapes;

- Said curvature means comprise two notches arranged back to back on the same line corresponding to a width of the frame;

- Said two notches are semi-circular notches of radius between 1 and 2 mm, preferably equal to 1.5 mm;

- said curvature means comprise two nipples projecting from the outer peripheral edge of the frame, on the same line corresponding to a width of the frame;

- Said nipples are breakable to be detached from the frame; and

- Said curvature means come from formation with the support.

FIGS. 8 to 10 represent the different stages of folding of an insulated transplanting electric wire using the support of the electrical apparatus of FIG. 1, and

- Figures 12 to 14 show, seen from the front and seen from the rear, two electrical devices comprising the support of Figure 1, associated and electrically connected.

In Figures 1 to 7, there are shown two embodiments of a support 100; 100 ’of electrical equipment intended to be fixed to a box (not shown) such as a box to be embedded in any wall, for example, a honeycomb wall or a box to be mounted projecting from such a wall.

Each support 100; 100 'is used for mounting inside the box or the housing of one or more switchgear mechanisms, such as a switch, socket, telephone socket, circuit breaker.

Here it is equipped with a power outlet mechanism.

Each support 100; 100 ’includes a frame 110; 110 ’flat, here square, defined between an outer peripheral edge 101; 101 'and an inner peripheral edge 102' (visible only in FIG. 6) which delimits a central opening for access to the electrical elements of the switchgear mechanism. This central opening has a generally square outline.

According to the embodiment shown in Figures 1 to 4, the support 100 forms a single piece with a base 200 forming a housing which extends behind the frame 110. Thus, here, the frame 110 forms a sidewalk or a rim around the base 200 and the inner peripheral edge of the frame 110 defines the access opening to the interior space of the base 200. This one-piece part is produced by molding a rigid plastic material.

According to the embodiment shown in Figures 5 to 7, the support 100 ’and the base 200’ are two separate parts. The generally square central opening of the support 100 ′ can accommodate a base 200 ′, two modules, the square facade of which fills the surface of the central opening of the support 100 ′, or two bases, one module, each of which rectangular shape fills half the surface of said central opening. For mounting the base 200 ′, the central opening of the support 100 ′ is bordered on its four sides by mounting means, here latching means, which comprise a hooking rib forming an edge falling from the face front of support 100 '. On this hooking rib are intended to hang on the locking teeth projecting from two opposite faces of the base 200 ’.

Each base 200; 200 ’is intended to house the electrical elements of the mechanism of the electrical apparatus. Here it houses the phase, neutral and earth electrical terminals of a power outlet mechanism.

Each base 200, 200 ’is open at the front, its opening corresponds to the central opening of the frame 110; 110 'from support 100; 100 ’. The front opening of the base 200; 200 ’is closed by a 210 cover; 210 '' reported on the base

200; 200 ’. This hubcap 210; 210 'gives the function of electrical equipment. Here, it forms a socket outlet, the bottom wall of which is pierced, on the one hand, with two openings for the insertion of the pins of a plug into the electrical terminals of phase and neutral, and, d On the other hand, an opening through which a ground pin, connected to the ground terminal, emerges inside the well.

As shown more particularly in Figures 3 and 6, each base 200; 200 ’is generally closed at the back and includes on the back, six circular openings 201,201 A, 202, 202A, 203, 203A; 201 201Ά, 202 ’, 202Ά, 203’, 203Ά giving access to three housings provided inside the base 200; 200 'to accommodate three pairs of electrical supply and transplanting terminals.

Indeed, here, each base 200; 200 ’accommodates in three housings (not visible in the figures) a couple of electrical phase terminals, a couple of neutral electrical terminals and a couple of electrical ground terminals. The electrical terminals of the same couple are electrically linked together, they include a power supply terminal to be connected to the electrical network and a transplanting terminal.

Two circular openings 201,201 A, 202, 202A, 203, 203A are provided; 201 ’, 201Ά, 202’, 202Ά, 203 ’, 203Ά by terminal housing, one of the circular openings 201,202, 203; 201 202 ’, 203’ giving access to the power supply terminal and the other of these openings 201 A, 202A, 203A; 201 Ά, 202Ά, 203Ά giving access to the transplanting terminal.

In a manner known per se, the section of these circular openings 201,

201 A, 202, 202A, 203, 203A; 201 ', 201Ά, 202', 202Ά, 203 ', 203Ά is adjusted to receive insulated electrical wires of cross section equal to 2.5 mm ² (and therefore also of cross section equal to 1.5 mm ² ), used for the power supply for each terminal. The stripped core of the end of an insulated electrical wire 1 is introduced into the base 200; 200 'via one of these openings 201,201 A, 202,

202A, 203, 203A; 201 ’, 201’A, 202’, 202Ά, 203 ’, 203Ά to be connected to the corresponding electrical terminal of the electrical equipment (see Figures 13 and 14).

As can be seen in Figures 1, 2 and 5, each support 100; 100 ’includes in each of the four branches of its frame securing means suitable for fixing it to the box or the housing. These securing means include a hole 105; 105 ’in the form of a keyhole, which extends generally circularly, being centered on the center C1 of the central opening of the support 100; 100 ’. Each hole 105; 105 'allows the passage of the threaded body of a fixing screw intended to be screwed into the box or the case not shown.

Advantageously, according to the embodiment shown in Figures 5 to 7, the frame 110 ’of the support 100’ is made of metallic material and it is overmolded with a skin 120 ’of insulating synthetic material. The skin 120 ′ of insulating synthetic material covers most of the front and rear faces of the frame 110 ’flat metal. It also covers the edge of this frame. The frame 110 'made of metallic material gives great rigidity to the support 100' and the skin 120 'of insulating material gives the user a feeling of electrical safety by forming electrical insulation. The combination of the 110 ’flat metal frame and the 120’ molded skin on this 110 ’frame makes it possible to obtain a 100’ aesthetic support of small thickness and high mechanical strength. The insulating material constituting the skin 120 ′ can be a plastic material such as a polymer loaded with glass fibers or ABS (Acrylonitrile Butadiene Styrene). Note in FIG. 5, that the skin 120 ′ forms around each bore 105 ′ an extra thickness 121 ′ and, that at this location, the frame 110 ′ of metallic material is visible.

Furthermore, it is provided in each of the four branches of the support

100; 100 ’on either side of each hole 105; 105 ’, clipping means 108; 108 ’of an embellished front plate not shown (see Figures 2 and 5).

As shown more particularly in Figures 1, 2, 3, 5 and 6, regardless of one or the other of the two embodiments shown, the support 100; 100 ’has 101 A, 101 B, 101C, 101D on each of the four sides; 101’A,

101 ’B, 101’ C, 101’ D of its outer peripheral edge 101; 101 ’assembly means 107; 107 ’to another medium of the same type.

Here, said assembly means 107; 107 ’provided on each side 101A, 101B, 101C, 101D; 101Ά, 101’B, 1O1’C, 101’D of the outer peripheral edge 101; 101 ’projecting therefrom a male element 107A; 107Ά and a female element 107B; 107’B.

Said assembly means 107; 107 ’come from training with support 100.

The assembly means 107; 107 ’include on each side of the outer peripheral edge 101; 101 'of each support 100; 100 ’, at least one lug 107A; 107Ά and notch 107B; 107’B of complementary shapes.

In the embodiment shown in Figures 1, 2 and 3, there are provided on each side 101 A, 101 B, 101C, 101D of the outer peripheral edge 101, two pairs of lugs 107A and notch 107B, spaced apart. of each other. In each pair, lug 107A and notch 107B are contiguous.

In the embodiment shown in Figures 5 and 6, there is provided on each side 101Ά, 101'B, 101'C, 101 'D of the outer peripheral edge 101', a lug 107Ά and, at a distance from this lug 107Ά , in correspondence with this, a notch 107'B of complementary contour.

These assembly means 107; 107 'identical provided on all sides of each support 100; 100 ’advantageously make it possible to associate the support 100; 100 'in all directions to one or more other 100 supports; 100 ’of the same type. Indeed, each support 100; 100 ’can be combined horizontally or vertically with another support 100; 100 'so as to form a vertical or horizontal row or even a square of supports 100; 100 ’.

The association of supports 100, shown more particularly in FIG. 12, is carried out such that the spacing L between the centers C1 of the central openings of the supports 100 is of the order of 71 millimeters. This distance corresponds substantially advantageously to the external width L of the support 100 (see FIGS. 8 and 9) or of the support 100 ’(see FIG. 6).

In this association configuration, as shown more particularly in FIGS. 13 and 14, the circular openings 201, 201 A, 202, 202A, 203, 203A giving access to the electrical terminals of the two electrical appliances are, by pair of terminals the same nature (phase, neutral and earth), spaced the same distance L.

To carry out an electrical transplanting from one electrical apparatus to another, the installer must then bend insulated electrical wires 1 to configure them to length L so that each electrical wire 1, the stripped ends of which are inserted, via said circular openings 201 A, 202A, 203A, in the two transplanting terminals of the same kind, can establish an electrical junction between said terminals (see FIGS. 13 and 14).

According to a remarkable characteristic of each support 100; 100 ’, frame 110; 110 ’incorporates, at two different locations, bending means 150; 150 ’suitable for bending an insulated electrical wire 1 immobilized against the frame 110; 110 ’, at two different places C of said insulated electrical wire 1, these two places being spaced by a distance between the internal and external widths of said frame 110; 110 ’.

Here, more particularly, the frame 110; 110 'having a generally rectangular shape with an external width L, said curvature means 150; 150 ’are arranged on the frame 110; 110 ’to form on the insulated electrical wire 1 immobilized against the frame 110; 110 ’, two distant curvatures C of a length substantially equal to said external width L of the frame (see FIG. 10).

Said curvature means 150; 150 ′ are advantageously distinct from said assembly means 107; 107 ’. They come from training with support 100; 100 ’.

According to the examples shown in the different figures, said curvature means comprise two notches 150; 150 'arranged back to back on the same line corresponding to a width of the frame 110; 110 ’.

As shown in Figures 4 and 7, said two notches 150; 150 ’are advantageously semicircular notches with a radius between 1 and 2 mm, preferably equal to 1.5 mm. The dimension of said notches 150; 150 '' such that they follow the curvature of the external surface of an electric wire

1.

Of course, as shown in FIG. 7, in the support 100 ’, the skin covers the edge of the notches 150’.

The notches 150; 150 'are positioned on a line which extends close to one side 101 A; 101Ά of the outer peripheral edge 101; 101 'of frame 110; 110 '', away from the assembly means 107; 107 ’. The rounded bottom of said notches 150 is spaced a distance d less than the external width

L of frame 110 (see figure 2).

Advantageously, as shown in FIGS. 1, 2 and 4, the front face of the support 100 carries, near each notch 150, a sign S which indicates to the installer that said notches 150 are used to bend the electric wire 1 into a U .

Finally, according to the embodiment shown in FIGS. 1 to 4, said curvature means also comprise two pins 151 projecting from the outer peripheral edge 101 of the frame 110, on the same line corresponding to a width of the frame 110. Each stud 151 adjoins a notch 150 (see FIG. 4). These pins 151 are preferably breakable (manually) to be detached from the frame 110 so that the support 100 can be assembled with its assembly means 107 to another support 100 of the same type without the stud 151 facing the other support. 100 does not interfere with this assembly (see Figure 12).

As shown in Figures 8 to 11, the installer advantageously uses the support 100 as a template to bend an electric wire 1 to form a U whose base has a length L which corresponds to the spacing provided between two circular openings 201 A , 202A, 203A giving access to the two transplanting terminals of the same nature of the two electrical devices associated by their support 100 (see FIGS. 12 to 14).

In a first step, it places the electric wire 1 against the front face of the support 100, on the line for positioning the notches 150, so that the electric wire 1 protrudes on either side of the support 100, in line with the notches 150 (see Figure 8).

Then, it engages each end part of the electric wire 1 which protrudes from the support 100 in each notch 150 to fold the electric wire 1 at right angles to the frame 110 of the support 100. By taking support on the support 100, it can , without moving the electric wire 1 from its support against the frame 110, form the two curvatures C in the electric wire 1. This electric wire 1 then has a U shape with two branches 1A and a base whose length L is substantially equal to the external width of the support 100 (see Figures 9 and 10).

Then, it slightly pulls the electric wire 1 towards it, the branches 1A of which slide in the notches 150 and it bears on the pins 151 to form another curvature in each of the branches 1A of the electric wire 1.

By resting on the pins 151, it can fold towards it an end part 1B of each branch 1A of the electric wire 1 so that it forms an acute angle of about 80 degrees with the rest of the branch 1A.

To assemble without difficulty two supports 100 of the same type, equipped with socket-outlet mechanisms, as shown in FIG. 12, the installer cuts, by hand or using a tool, the stud 151 of each support 100 facing the other support 100 so that these pins do not hinder the cooperation of the assembly means 107 of said supports 100.

Each stripped end part 1B of the electrical wire 1 will be easily inserted via a circular opening 201 A, 202A, 203A of the base 200 into a transplanting terminal of each electrical appliance and the electrical wire 1 then establishes the electrical junction between the terminals transplanting by being correctly pressed against the rear face of the bases 200 of the electrical equipment (see Figures 13 and 14).

If the installer uses the support 100 ’as a bending template for an electrical wire 1, it forms the U-shaped electrical wire using the notches 150’, as has just been explained above; but, due to the absence of the pins on this support, simply, it introduces the stripped ends of the branches of the U-shaped electric wire into the corresponding electric terminals then it folds the electric wire against the rear face of the base, which has for consequence of forming the second folds or curvatures.

In the embodiment shown in FIGS. 5 to 7, the support 100 ′ comprises on two opposite parallel branches two detachable portions 100 chacune which each extend over at least part of the length of the branch concerned, here, over the entire length of the branch concerned of the support 100 '. Each detachable portion 100Ά is connected in one piece to the relevant branch of the support 100 ’by a break line 130’ of lower resistance.

As shown in Figure 4, the two notches 150 ’are placed back to back on one of the break lines 130’.

In addition, each concerned branch of the support 100 'comprises, on the one hand, in the eccentric position, locally projecting from said break line 130', a lug 142 'which said detachable portion 100Ά bypasses by a notch, and, on the other hand, at a distance from this lug 142 ', in correspondence with the latter a notch 141' of complementary contour.

Thus, advantageously if desired, the user can break one of the break lines 130 'to detach a detachable portion 100Ά in order to release the lug 142' and the corresponding notch 141 'and to associate this support 100' to another support 100 'of the same type whose detachable portion 100Ά has also been detached by breaking from the corresponding break line.

When the detachable portion 100Ά is detached from the support 100 ’the assembly means 142’, 141 ’which constitute the corresponding lug and notch protrude from the new edge formed by the break of the break line 130’.

In this way, the user can associate two supports 100 ’with a center distance of 57 millimeters, that is to say that the centers C1 of the central openings of the supports 100’ are distant by a length equal to 57 millimeters.

However, in this case, the notches 150 ′ are ineffective either because they are destroyed during the breaking of the breaking line 130 ′ on which they are placed, or because they are of no use since they are too far apart for form the electrical wire at the correct length of spacing between the electrical terminals of the associated equipment.

The present invention is not limited to the embodiments described and shown in the various figures, but the person skilled in the art will be able to make any variant which conforms to his spirit.
