[0001] TECHNICAL FIELD TO WHICH THE INVENTION RELATES The present invention generally relates to the installation of electrical equipment in an electrical box to be embedded in a wall and the connection of this electrical equipment. It relates more particularly to a connector, comprising: - a base which defines an inlet opening for at least one electrical conductor, and - at least one connection element fixed to the base, which comprises an input terminal for the connection of said conductor electrical and an output terminal accessible from the front of the base for the connection of said electrical equipment. It also relates to an assembly comprising: - a connector as mentioned above, and - an electrical box intended to house electrical equipment and having a side wall which is closed at the rear by a bottom wall having at least one access opening at the output terminals of the connection elements of the connector.
[0002] BACKGROUND ART Generally, an electrical box comprises, internally, means for securing electrical equipment, and, externally, fastening means to a wall. An ordinary electrical box further comprises, in the rear part, knockouts that allow the bottom of the box to be opened locally in order to introduce into its interior volume ducting ducts from which emerge the electrical conductors necessary for serving the electrical equipment. . These boxes have standard sizes. Thus, commonly, a recessed circular electrical box has a standard diameter of 68 millimeters and a usual depth of 40 millimeters. The internal volume of such an electrical box is then reduced and it is not easy to accommodate not only the electrical equipment, but also the end of the duct and the ends of the electrical conductors that were pulled in the inner volume of the electrical box, in particular due to the rigidity of the electrical conductors which must be folded between the electrical equipment and the bottom of the box. This small interior volume therefore restricts the possibilities of evolution of electrical equipment which, because of their limited sizes, can not indeed integrate all the desired functions. A solution currently used to house large electrical equipment then consists of providing two electrical boxes next to each other, one of which houses the electrical equipment while the other houses the electrical conductors.
[0003] This solution is however expensive and tedious to implement. Another solution is described in EP2068411. This alternative is to use an electrical box that accommodates, through a window in the bottom, a connector adapted to facilitate the connection of the electrical equipment to the electrical conductors from the duct. This connector comprises for this purpose electrical terminals accessible from the inside of the box for the connection of the electrical equipment, and a portion of cable to be connected to the electrical conductors. This solution avoids having to introduce electrical conductors and ducts into the interior of the electrical box, which allows to provide more space to the electrical equipment. The major disadvantage of this solution is that it does not block the end of a tracking sheath against the box. This solution therefore requires either to do all the electrical installation with electrical cables of the kind comprising insulated electrical son embedded in an insulating sheath (which is more expensive than using ducts in which are freely drawn son isolated electric means), or to provide expensive means for creating a connection between the electrical cable and a routing duct. OBJECT OF THE INVENTION In order to overcome the aforementioned drawbacks of the state of the art, the present invention proposes a solution which, on the one hand, avoids having to introduce the electrical conductors and the tracking ducts into the interior volume. of the electrical box, and, secondly, can easily mount and dismantle the electrical box in the wall.
[0004] More particularly, the invention proposes a connector as defined in the introduction, which comprises at least two distinct arms which extend from the base, towards the front, and whose free ends have means for hanging on the wall.
[0005] Thus, the connector is intended to attach, not to the electrical box, but rather to the wall itself. It is thus likely to be put in place before the electrical box. Once in place, he can hold between his arms the electric box. Therefore, thanks to the invention, it is possible to remove the electrical box from the wall without driving with it routing ducts and electrical conductors, since the latter are attached to the connector. Extraction and engagement of the box in or out of the wall can then be done without difficulty. Another advantage of this connector is that it allows access, when it is in place on the wall, to the ducts, via the space between the base and the wall. It is thus possible to drive the ducts in the desired direction, which facilitates the installation of the connector. Moreover, since the connection of the tracking ducts is performed on the connector, the electrical box ensures thermal insulation between the inside and outside of the wall to meet the standards in force (in France, the BBC standards for "low energy building"). This connector also has the advantage of ensuring good electrical insulation since, in the absence of electrical equipment in the electrical box, the electrical connection terminals of the connector remain hidden at the rear of the electrical box. Other advantageous and non-limiting features of the connector according to the invention are the following: - only two arms are provided which are situated opposite each other with respect to the center of the base; the arms extend from the edge of the base in parallel directions; - said inlet opening is located in the extension of a first of the arms; - The base has a bottom wall which is lined at the front by a peripheral rim; - said peripheral rim has two notches located on either side of a second of the two arms and which are contiguous to the second arm; said hooking means are formed by the free ends of the arms which are bent outwards; - There is provided a tip which defines at least one passage for said electrical conductor and which comprises a mounting portion for mounting on the base, in the axis of said inlet opening, and at least a securing portion for securing a routing sheath housing said electrical conductor; - The mounting portion comprises a tubular conduit which externally has a peripheral groove engaged on the edge of the inlet opening of the base; - The mounting portion comprises a tubular conduit and at least two latching lugs adapted to hook at the edge of the entrance opening of the base; - The mounting portion is shaped to leave at least a rotational mobility to the tip relative to the base, about an axis inclined relative to the axes in which the arms extend; - The mounting portion is shaped to form, with said inlet opening, a ball joint; - The base comprises indexing means for locking the rotation of the tip relative to the base; the mounting portion is shaped to securely lock the tip relative to the base and each securing portion has a juncture area at said mounting portion which is manually flexible; each tubular duct has a flexible portion extended at its free end by a rigid collar; the mounting part comprises sliding means making it possible to return the endpiece in the axis of the inlet opening, and detent teeth making it possible to block the endpiece in this position with respect to the opening entrance; - Each securing part comprises a tubular conduit fitted internally with a retaining means of the duct; - there are two separate sections of liability; the tubular ducts of the two securing parts extend side by side, in parallel with each other; each securing part comprises a succession of tubes of different diameters; said tip is formed in one piece by molding; the pedestal comprises a bottom wall which bears on the front face partitions, these partitions delimiting isolated receiving receptacles which accommodate said connection elements; - The input terminal of each connection element has at least one slot whose edges are sharp for slicing the insulating sheaths of the electrical conductors; - The input terminal of each connection element is equipped with an operating lever adapted to force the electrical conductor to engage in said slot; - Each operating lever is rotatably mounted about an axis parallel to the bottom wall; the orthogonal projections, in the plane of the front face of the bottom wall, the axis of rotation of at least one operating lever and the axis of the inlet opening are parallel; several connection elements are provided which are arranged in such a way that their output terminals are contiguous and that their input terminals are situated at a distance from one another; - The base defines at least two separate positions in each of which there is provided an inlet opening and at least two connecting elements, and there is provided at least three separate arms. The invention also provides an assembly as defined in the introduction, which comprises a connector as mentioned above and an electrical box whose side wall externally has at least two grooves 30 of the arms of the connector. Advantageously then, said access opening is closed by a detachable or knock-out cap. Advantageously, the edge of said access opening is covered by a seal.
[0006] Advantageously also, said lid is overmolded on a portion of the bottom so as to have, on the one hand, a bulge which runs along the edge of said access opening to form said seal, and on the other hand , a tear line of lesser thickness which runs along the edge of said bulge. Preferably, the side wall of the electrical box is lined at the front by an outside sidewalk which is interrupted for the passage of the arms of the connector. The invention also relates to a method of mounting a connector as aforesaid in a cavity in a wall, comprising the steps of: - threading an electrical conductor through the inlet opening of the connector base, connecting said electrical conductor to the input terminal of the connection element of the connector, and engaging the base in said cavity so that the attachment means provided at the free ends of the arms catch on the wall . The invention also relates to a method of mounting an assembly as aforesaid in a cavity made in a wall, comprising: a step of mounting the connector in said cavity according to the aforementioned method, and then a step of mounting the electrical box in said cavity, engaging the grooves provided in the side wall of the electrical box on the arms of the connector such that the access opening provided in said bottom is placed opposite the output terminals of the elements of connector connection.

[0007] As a preliminary, it should be noted that the identical or similar elements of the different embodiments of the invention shown in the different figures will, as far as possible, be referenced by the same reference signs and will not be described each time. The installation of electrical equipment in a recessed position in a wall requires to provide a cavity in this wall. We will consider here that the wall that hosts the electrical equipment is a hollow partition. Of course, the electrical equipment could be installed on another type of wall, such as for example a masonry wall. Recall that, in known manner, a hollow partition is generally composed of a metal frame (formed of vertical uprights and horizontal rails not shown) and gypsum panels reported on at least one of the two faces of the metal frame. As shown in FIG. 1, the cavity formed in this hollow partition is here simply formed by a circular opening 301 made in a bell saw in one of the plasterboards 300 of the hollow partition. In the description, the terms "front" and "rear" will then be used with respect to the direction of gaze of the installer of the electrical equipment in this circular opening 301. Thus, the terms front and rear respectively designate the place turned towards the outside of the hollow partition and the place facing the interior of the hollow partition. The invention does not relate to electrical equipment, the latter has not been shown in the figures. It could for example be a switch, a socket, a back and forth, an electric dimmer, a network jack (RJ45), a telephone jack ( RJ11), a light, or a detector (smoke, flood, temperature, movement or light). It will be noted only that this electrical equipment will have on the rear face means to allow its connection to the local electrical network and / or the local data network. Here, these means will consist of three flat pins extending rearwardly.
[0008] As shown in FIG. 10, the local electrical network is here conveyed by three electrical conductors 401, 402, 403 (of phase, of earth and of neutral) whose free ends open out from a routing sheath 400. In practice, these Electrical conductors are sheathed electrical wires 401, 402, 403, for example copper wires covered with a plastic envelope. The tracking sheath 400 is itself flexible and annular type. It comprises a tubular wall formed of a succession of rings which delimit between them grooves. As shown in the figures, this duct sheath 400 is housed inside the hollow partition, so that its free end can be pulled through the circular opening 301 made in the plasterboard 300. As shown in FIG. 14, the electrical equipment is intended to be housed in an electrical box 200 that is recessed through this circular opening 301. The electrical box 200 then makes it possible not only to rigidly fix the electrical equipment in the wall but also to protect him. As shown in Figures 1 and 2, this electrical box 200 here has a generally cylindrical shape, but it could of course have a different shape, including parallelepiped. It comprises a tubular side wall 210 of revolution about a main axis Ai, which is closed at the rear by a bottom 220 and which is open towards the front. The electrical box 200 thus delimits an inner housing for receiving the electrical equipment.
[0009] For fixing it in the circular opening 301 made in the gypsum board 300, the electric box 200 comprises an external sidewalk 230 which runs along the edge of the front opening of the side wall 210 and which is adapted to bear against the front of the gypsum board 300, around the circular opening 301. Thus, this sidewalk 230 allows it to block the electrical box 200 backwards. For its blocking forward, the electrical box 200 comprises fastening means 240 which are adapted to hook on the back of the gypsum board 300. These fastening means could be in the form of claws that would intervene in diametrically opposed position on the outer face of the side wall, and which, under the control of screws, could cling to the back side of the plasterboard. Here, these fixing means 240 are formed in one piece with the rest of the electrical box 200. They comprise rectangular shutters 241 cut into the side wall 210 of the electrical box 200 in such a way that they are connected to that only by their front edges, the latter then forming a kind of hinge. Each flap 241 bears on its outer face flexible parallel ribs 242. Each flap 241 is thus free to retract into the interior of the electrical box 200 when the electrical box 200 is engaged through the circular opening 301 provided in the plasterboard 300, then to return to its initial position so that its flexible parallel ribs 242 can cling to the rear face of the plasterboard 300. The flaps 241 are then locked in this position by the electrical equipment itself, which is shaped so that it pushes them outward. The electrical box 200 also comprises securing means 250 of the electrical equipment.
[0010] These securing means could be in the form of screwing wells which would rise from the bottom of the electrical box, forward, along the inner face of the side wall, and which would accommodate screws. fixing the electrical equipment. Here, these securing means comprise two diametrically opposite cavities 250, recessed in the inner face of the side wall 210 of the electrical box 200, in which snap-fastening means provided on the electrical equipment can be hooked. As shown in Figure 1, to facilitate the connection of the electrical equipment to the sheathed electrical son of the local electrical network, there is provided a connector 1. The present invention relates more particularly to this connector 1. As shown in Figures 1 and 8, the connector 1 comprises a base 10 and connecting elements 31, 32, 33 fixed to the base 10. The base 10 is provided to be placed behind the bottom 220 of the electrical box 200. It then has a such that it can cover most of the bottom 220, so as to form with it a double bottom. This base 10 here comprises a flat bottom wall 12, generally circular around the main axis Ai, which is lined at the front by a peripheral flange 13 adapted to bear against the electrical box 200 (see Figure 2). As shown in Figure 3, the base 10 defines an inlet opening 11 provided to be traversed by the sheathed electrical son 401, 402, 403.
[0011] As is more particularly shown in FIG. 8, here, on the front face of the bottom wall 12, three connecting elements 31, 32, 33 of phase, neutral and earth are provided for the connection of the three sheathed electrical wires. 401, 402, 403. Alternatively, a small number (for example two, of phase and neutral) or an increased number (for example, four in the case of a back and forth) could be provided. . Each of these connection elements 31, 32, 33 comprises an input terminal 31A, 32A, 33A for the connection of one of the sheathed electrical wires 401, 402, 403, and an output terminal 31B, 32B, 33B accessible by the front of the base 10 20 for the connection of the pins of the electrical equipment. According to a particularly advantageous characteristic of the invention, the connector 1 comprises at least two distinct arms 14, 16 which extend from the base 10, towards the front, and whose free ends have attachment means 15, 17 at the wall. As shown in FIG. 13, these two arms 14, 16 thus make it possible to position the connector 1 on the plasterboard 300, before bringing the electrical box 200 back. The two arms 14, 16 extend over lengths such that once hooked to the plasterboard 300, they hold the plinth 10 at the back and away from this plasterboard 300. Thanks to the free space left between the plinth 10 and the plasterboard 300, it is It is possible to easily push the track sleeve 400 into the hollow partition, manually guiding it so that it is positioned in the desired direction.
[0012] In the embodiment shown in FIGS. 1 to 14, the connector 1 comprises only two arms 14, 16 which are located opposite each other with respect to the main axis A1. As shown in FIG. 3, these two arms 14, 16 extend from the front edge of the peripheral rim 13 of the base 10, in the extension of the peripheral rim 13, and in parallel directions. These two arms 14, 16 are straight. More precisely, they present here generally rectangular shapes, with two rectilinear lateral edges 14A, 16A, and a front end edge 14B, 16B in an arc-of-circle. The front end edges 14B, 16B of the two arms 14, 16 are circumscribed to a same circle which is centered on the main axis Al and which has a diameter equal to that of the circular opening 301 of the gypsum board 300. The free ends of these two arms 14, 16 are bent outwards, so as to form flanges 15, 17 which extend radially from the front end edges 14B, 16B of the two arms 14, 16, in opposite directions. These flanges 15, 17 are thus adapted to bear against the front face of the plasterboard 300, so that they form said "hooking means" of the arms 14, 16 to the wall. The arms 14, 16 are formed here in one piece with the base 10, by molding a plastic material. Alternatively, it could be provided that the arms are reported, for example by snapping, on the base. It could also provide that the base is in two parts reported one on the other. Here, the inlet opening 11, which allows the passage of the sheathed electrical son 401, 402, 403 from the outside and the rear of the base 10 inwardly and the front of the base 10, has a shape circular, of sufficient diameter to allow the simultaneous passage of these three sheathed electrical son 401, 402, 403. This inlet opening 11 is preferably located in the extension of a first of the two arms 14. It is more precisely located in a A flat portion 11 A which straddles the bottom wall 12 and the peripheral flange 13, and which is inclined relative to the main axis Al. As shown in FIG. 5, this flat part 11 A is here inclined to 45 degrees with respect to the main axis Ai, so that the angle formed between the main axis Al and the axis A2 of the inlet opening 11 is 45 degrees.
[0013] As shown more particularly in FIG. 3, the peripheral rim 13 advantageously has two notches 18 which are situated on either side of the second of the two arms 16 (that located opposite the inlet opening 11) and adjacent to this second arm 16. These notches 18 each extend over an angular sector which is greater than 20 degrees around the main axis A1, and which is here approximately equal to 50 degrees. These notches 18 are provided to facilitate the engagement of the connector 1 through the circular opening 301 made in the plasterboard 300. Thus, as shown in Figures 10 and 13, after engaging the base 10 in the opening 301 by its side which carries the first arm 14 (namely the side from which the sheathed electrical wires 401, 402, 403 open), the notches 18 allow the base 10 to tilt so that its second arm 16 can also engage in the circular opening 301, avoiding that the peripheral rim 13 abuts against the gypsum board 300.
[0014] As shown in Figures 13 and 14, once the connector 1 in place, the risk is that these arms 14, 16 form an obstacle to the engagement of the electrical box 200 in the circular opening 301. To avoid interference between the electrical box 200 and the connector 1, as shown in Figure 1, the side wall 210 of the electrical box 200 has recessed in its outer face, two grooves 214, 216 whose dimensions are adjusted to those of the arms 14, 16 , to allow the passage of these last. It can also be seen in FIG. 1 that the external pavement 230 of the electrical box 200 is interrupted in the extension of these two grooves 214, 216, to allow the passage of the flanges 15, 17 of the connector 1. Here, advantageously, the connector 1 has a tip 100 designed to ensure the maintenance of the duct sheath 400 relative to the base 10 and to ensure a seal between these two elements. As shown in Figure 4, this nozzle 100 defines at least one passage 101, 102 for the sheathed electrical son 401, 402, 403. It comprises a mounting portion 110 for mounting on the base 10, in the axis of said inlet opening 11, and at least one securing portion 120, 130 for securing the passage sheath 400. In practice, this endpiece 100 will delimit at least two separate passages 101, 102 for sheathed electrical wires 401, 402, 403 from two ducts 400. It will then comprise at least two securing parts 120, 130 for securing these two ducts 400.
[0015] One of these ducts 400 is that described above, that is to say that in which the sheathed electrical son 401, 402, 403 circulate from the local electrical network. The other of these ducts is used if it is desired to connect another electrical equipment in derivation of the electrical equipment in question (we speak of transplanting). This other sheath is then designed to protect the sheathed electrical son allowing this subculture. The securing parts 120, 130 each comprise a tubular duct 121, 131 of axis A3 and of inside diameter equal, with the mounting clearance, to the outside diameter of the ducting sheaths 400. These two tubular ducts 121, 131 are preferably juxtaposed, so that they extend side by side, parallel to each other, and they open in the same direction. As shown in Figure 2, each tubular duct 121, 131 is internally equipped with a retaining means 122, 132 of a duct 400.
[0016] Here, these retaining means are simply formed by ribs 122, 132 which project from the inner face of the tubular ducts 121, 131. These ribs 122, 132 extend in length in planes perpendicular to the axes A3 and have profiles such that they can engage in the grooves of the ducts 400 to ensure the locking of the ends of these ducts 400 inside the tubular conduits 121, 131. As shown in Figures 4 and 5 , the mounting portion 110 of the nozzle 100 on the base 10 comprises a tubular conduit 111 of revolution about an axis A2, which externally has a peripheral groove 112 engaged on the edge of the inlet opening 11 of the base 10. Here, the tip 100 is made in one piece by molding a softer material than that of the base 10, which facilitates the assembly of the mounting portion 110 on the edge of the opening. input 11 of the base 10. Alternatively, it could be provided that the tip is made of the same material as the base, in which case the assembly must be made in force. Since the mounting portion 110 of the nozzle 100 and the inlet opening 11 of the base 10 have forms of revolution about the axis A2, it is understood that the tip 100 is free to pivot relative to the base 10 , around the A2 axis. This characteristic is advantageous insofar as the axes A3 of the tubular ducts 121, 131 of the securing parts 120, 130 are inclined with respect to the axis A2 of the tubular duct 111 of the mounting part 110. In fact, these three tubular conduits 111, 121, 131 are here joined together by an intermediate portion flared and slightly bent so that the axes A3 extend in a plane inclined at 45 degrees with respect to the axis A2. In this way, as shown in Figures 4 and 5, by pivoting the nozzle 100 relative to the base 10, it is possible to orient the axes A3 is laterally (Figure 4) in a plane parallel to the gypsum board 300 , towards the back (Figure 5). It is thus possible to orient the ducts 400 in the desired direction, to facilitate their return in the hollow wall. Figures 6 and 7 show an alternative embodiment of the tip 100. In this variant, the securing portions 120, 130 remain identical to those shown in Figures 4 and 5. Only the mounting portion 110 exchange. Here, the mounting portion 110 comprises a tubular conduit 115 of revolution about the axis A2 and two detent tabs 116 located diametrically opposite to the axis A2. These two latching tabs 116 rise in parallel from the edge of the tubular duct 15. They have on their outer faces teeth adapted to hook at the edge of the inlet opening 11 of the base 10. In this embodiment, Alternatively, the tip 100 is made in one piece by molding a material identical to that of the base 10. Of course, alternatively, it could be provided that the tip is made of a different material from that of the base. In this variant, as shown in FIG. 7, the tubular duct 115 has four notches 117 located in pairs on either side of each detent lug 116. These notches 117 allow the snap tabs 116 to flex more easily. when assembling the tip 100 on the base 10. As has been explained above, the tip 100 may be oriented in the desired manner with respect to the base 10, so that its tubular conduits 121, 131 are directed either backwards or parallel to the gypsum board 300. It can then be provided that the base 10 includes indexing means for locking the tip 100 in one or other of these two positions. Thus, it can be provided that the edge of the inlet opening 11 of the base 10 has two lugs (not shown) adapted to engage in the notches 117 of the tip 100 when the latter is in one or the other of these two positions. According to another embodiment of the nozzle not shown in the figures, it could have been provided that the mounting portion of the nozzle has an outer face in the form of a sphere section, and that the edge of the opening of FIG. The entrance of the base has a corresponding shape, so that the connection between the tip and the base form a ball joint. Whatever its shape, the end piece 100 makes it possible to bring the sheathed electrical wires 401, 402, 403 into the base 10, towards the three connection elements 31, 32, 33. As shown in FIG. connecting elements 31, 32, 33 are fixed in receiving housings 21, 22, 23 which are isolated from each other and which are delimited by partitions 20 rising from the front face 25 of the wall of bottom 12 of the base 10. In practice, each receiving housing 21, 22, 23 is delimited by four partitions arranged in a rectangle. Two opposing partitions of each housing here have teeth 24 facing each other in order to block the connection elements 31, 32, 33 in the base 10. These three receiving housings 21, 22, 23 are positioned one at a time. relative to the others T, with a first housing 22 which extends from the peripheral rim 13 of the base 10, at the second arm 16, to the center of the base 10. The other two housing 21, 23 s' extend on either side of it, at right angles.
[0017] The first housing 22 is provided to receive the earth connection element 32, while the other two housing 21, 23 are provided to accommodate the connection elements 31, 33 of phase and neutral. These connection elements 31, 32, 33 are all derived from cutting and folding a metal strip. Their input terminals 31A, 32A, 33A have identical shapes. It could be automatic terminals. Thus, for example, these input terminals could each comprise a leaf-spring delimiting an insertion and automatic locking duct of a stripped end of a sheathed electrical wire. It could also be screw terminals, including screws adapted to block and connect the sheathed electrical son. Here, to facilitate the work of the installer, it is rather fast connection terminals, each equipped with an operating lever 41, 42, 43.
[0018] Each input terminal 31A, 32A, 33A thus has a rectangular and flat rear wall 311A, 321A, 331A intended to rest against the bottom wall 12 of the base 10, flanked by two folded side walls 312A, 322A, 332A. at right angles to the front relative to the rear wall 311A, 321A, 331A. Each operating lever 41, 42, 43 has here a rectangular plate shape mounted to rotate relative to the base 10, between an open position in which it discovers the input terminal to allow to bring back one of the son sheathed electrical 401, 402, 403, and a closed position in which it closes the housing 21, 22, 23 of this terminal. Here, each operating lever 41, 42, 43 is rotatably mounted on the corresponding input terminal 31A, 32A, 33A. The side walls 312A, 322A, 332A of each input terminal 31A, 32A, 33A are respectively pierced by two eyelets 313A, 323A, 333A coaxial in which are engaged pins 41A, 42A, 43A provided on both sides. 1 of each operating lever 41, 42, 43. To keep them in the closed position, the operating levers 41, 42, 43 have on their edges teeth 41B, 42B, 43B adapted to snap into cavities provided in the partitions 20. To cut the sheath of the sheathed electrical son or wires 401, 402, 403 which are reported, the side walls 312A, 322A, 332A of each input terminal 31A, 32A, 33A have two slots 314A, 324A , 334A which extend in parallel. Each slot 314A, 324A, 334A extends from the front edge of the corresponding side wall 312A, 322A, 332A, to the vicinity of the rear wall 311A, 321A, 331A, in an arc of a circle centered on the eyelet 313A, 323A, 333A corresponding. The edges of these slots 314A, 324A, 334A are sharpened to slice the insulating sheaths of the sheathed electrical wires 401, 402, 403 to establish an electrical connection.
[0019] As shown in Figures 8 and 9, each operating lever 41, 42, 43 has on its rear face a groove 41C, 42C, 43C which allows to hang the corresponding sheathed electrical wire so as to force it to engage in the slots 314A, 324A, 334A of the corresponding input terminal. The output terminals 31B, 32B, 33B of the connection elements 31, 32, 33 are themselves shaped to receive the flat pins of the electrical equipment. They form here cells for receiving these pins. Alternatively, if the electrical equipment were provided at the rear of pin receiving cells, the output terminals of the connecting members would have been provided with forwardly extending pins. The connecting elements 31, 32, 33 are arranged in their receiving housings 21, 22, 23 in such a way that their output terminals 31B, 32B, 33B are contiguous (i.e., located near each other). another, here near the center of the base 10) and that their input terminals 31A, 32A, 33A are spaced apart from each other. As shown in FIG. 11, they are also housed in their receiving housings 21, 22, 23 in such a way that the pivot axes A41, A42, A43 of the operating levers 41, 42, 43 are all parallel to the The pivot axis A42 of the operating lever 42 of the earth connection element 32 is more precisely oriented orthogonally with respect to the axis A2 of the inlet opening 11 of the base plate 12 of the base 10. The base, and the pivot axes A41, A43 of the other two operating levers 41, 43 are oriented perpendicularly to the first pivot axis A42.
[0020] Otherwise formulated, the orthogonal projections, in the plane of the front face of the bottom wall 12 of the base 10, these two pivot axes A41, A43 and the axis A2 of the inlet opening 11 are parallel. In this way, as shown in FIGS. 12 and 13, to engage the sheathed electrical wires 403, 401 in the input terminals 31A, 33A of the connection elements 31, 33 of phase and neutral, it is not necessary to bend them excessively. Of course, alternatively, the operating levers could be arranged otherwise in the base. As shown in FIGS. 8 and 11, the connector 1 further comprises a cover 50 to be snapped over the partitions 20 of the base 10, in the center of the latter, to hide the output terminals 31B, 32B, 33B of the elements of FIG. connection 31, 32, 33. This cover 50 has a square plate shape. It comprises a central opening 52 for access to the output terminal 32B of the earth connection element 32, and two arc-shaped openings 51, 53 which are centered on the central opening 52 and which provide access at the output terminals 31B, 33B of the two other connection elements 31, 33. As shown in FIG. 14, the bottom 220 of the electrical box 200 also has at least one access opening 221 to allow the connection of the switchgear at the connector 1. It has here a single circular access opening 221, centered on the main axis A1. This access opening 221 has a diameter greater than that of the arcuate openings 51, 53 of the cover 50, so that it allows simultaneous access to the three output terminals 31B, 32B, 33B connection elements 31, 32, 33 of the connector 1. This access opening 221 is initially closed by a cap 222 detachable or knockout. This is a detachable lid 222, which is overmolded on the body of the electrical box 200 and which has on the front face a tongue 223 facilitating its tearing.
[0021] With this detachable cover 222, when the electrical box 200 is placed in the gypsum board 300, it is possible to paint the latter by preventing the paint from covering the output terminals 31B, 32B, 33B of the elements. connection 31, 32, 33 of the connector 1. Referring to Figures 10 to 14, can be described in detail the establishment and connection of the electrical equipment in the hollow wall. Initially, a circular opening 301 is made with a hole saw in the gypsum board 300 of the hollow partition, so that the free end of a routing sheath 400 can be pulled out of the hollow partition, through this circular opening 301. As shown in FIG. 10, the ends of the sheathed electrical wires 401, 402, 403 emerging from this routing sheath 400 are then engaged through the end piece 100 and the opening of the opening. 11 of the base 10, then the end of the duct 400 is blocked in one of the tubular conduits 121 of the nozzle 100. After raising the operating lever 41 mounted on the connecting element 31 of phase , the installer folds the insulated electrical wire 401 of neutral so as to place the end of this wire above the mouths of the slots of the input terminal of this connection element 31. It then folds the operating lever 41 in p closed osition, which has the effect of forcing the insulated electrical wire 401 neutral to engage in the slots of this input terminal. The insulating sheath of this wire is thus automatically cut, which makes it possible to establish an electrical contact between the wire and the output terminal of this connection element 31.
[0022] As shown in FIG. 11, the installer then folds the insulated electrical wire 402 of earth so that it bypasses the reception housing 23 of the phase connection element 33 and passes between it and the peripheral rim 13 of the base 10. To facilitate the establishment of this wire, the installer places the operating lever 43 of the phase connection element 33 in the open position. The installer then proceeds in the same manner as above to connect the insulated earth wire 402 to the input terminal of the earth connection member 32. The installer also proceeds in the same manner as mentioned above for connecting the insulated phase electrical wire 403 to the input terminal of the phase connection element 33 (see FIG. 12). When the installer closes the operating lever 43 of the phase connection element 33, the operating lever 43 is naturally placed above the sheathed electrical wire 402 earth, which keeps the latter in position. For this purpose, the operating lever 43 is provided for overflowing from the reception housing 23 of the phase connection element 33. Note that to connect the sheathed electrical son 401, 402, 403, the installer will not have had to cut to the desired length since if these son are particularly long, their ends can be pulled through the notches 18 of the base 10. These wires will be cut to the correct length after connection, which will facilitate the work of the installer. Note also that if the installer wishes to transplant another electrical equipment in parallel with the one considered, he can engage a second routing sleeve in the end piece 100, then he can connect the three son from the second duct path in the slots of the input terminals 31A, 32A, 33A of the connecting elements 31, 32, 33, above the sheathed electrical wires 401, 402, 403 mentioned above. As shown in Figure 13, the connector 1 is then put in place through the circular opening 301 made in the plasterboard 300, first by engaging it by its side which emerges the sheath or ducts. 400, then by tilting without difficulty through the notches 18 in the base 10. The connector 1 is placed all the more easily in the hollow wall that, thanks to the small thickness of the base 10, the installer keeps a access to the duct or ducts 400 during the installation of the connector 1 in the wall, so that it can push them back in the desired direction with greater ease. The installer can also orient the tip 100 relative to the base 10 in the desired manner, before installing the connector 1 in the wall, which also facilitates the backflow of the duct or ducts 400. The connector 1 is considered in place when the flanges 15, 17 of the arms 14, 16 bear against the front face of the plasterboard 300. As shown in Figure 14, then remains for the installer to engage the electrical box 200 through the circular opening 301 made in the gypsum board 300, which is done without difficulty thanks to the grooves 214, 216 provided on the outer face of the side wall 210 of the electrical box 200. The electrical box is considered in place when its bottom is pressed against the base 10 and that the access opening provided in its bottom is placed opposite the output terminals of the connection elements of the connector 1. The present invention is not limited to the mode of e embodiment described and shown, but the skilled person will be able to make any variant within his mind.
[0023] In particular, as shown in Figures 15 and 16, we can provide to use a connector 501 of different shape in the case where the electrical box to engage in the wall is a multi-station box, that is to say a box suitable for two or more electrical appliances. In these figures 15 and 16, there is shown a connector 501 intended to be used in combination with a two-station electrical box (not shown). This connector 501 then has a base 510 which delimits two separate positions 510A, 510B. Each station has an architecture almost identical to that of the connector 1 shown in FIGS. 1 to 14. Only slightly changes the shape of the bottom walls 512A, 512B and peripheral rims 513A, 513B of these two stations 510A, 510B, since these walls and flanges meet at a level of a rectilinear partition 520. Each station 510A, 510B thus has in particular an inlet opening 511A, 511B, three connecting elements (not visible), and three operating levers 541A, 542A, 543A, 541B, 542B, 543B. In this connector 501, at least three separate arms 514, 516 are provided to ensure better attachment of the connector 501 to the wall. In this case, it is here provided four arms distributed in pairs at each station 510A, 510B. FIG. 17 shows another variant embodiment of the connector 1. In this variant, the base 10 and the connection elements housed in this base 10 comprise shapes that are homologous to those of the base 10 and the connection elements of the base 10. connector 1 shown in Figure 1. The operating levers 41, 42, 43 have slightly different shapes, more tapered, which does not affect their operation. It will first be noted in this variant that the peripheral rim 13 of the base 10 is not interrupted along the notches 18, but that it also borders the bottom wall along these notches 18.
[0024] Note also that the cover 50 has a shape slightly different from that shown in Figure 8. This embodiment of the cover 50 will be described in detail later in this discussion, with reference to Figures 20 to 23.
[0025] As shown in Figure 17, the tip 100 has a shape substantially different from that of the tip shown in Figure 1. It is also molded in one piece of softer material than the body of the electrical box , here in SEBS. As shown in FIGS. 18 and 19, in this variant, the end piece 100 further comprises a mounting part 110 for mounting it on the base 10, and two securing parts 120, 130 for securing two sheaths of 400 The mounting portion 110 comprises a tubular duct 113 of oblong section which externally has a peripheral groove 114 engaged on the edge of the inlet opening of the base 10. In this variant, the inlet opening will present Also oblong shape, so that the mounting of the mounting portion 110 on the base 10 will provide a rigid attachment of these two elements relative to each other. The two securing parts 120, 130 are here identical. They each delimit a passage for the electrical wires. They each have, at their junction with the mounting portion 110, a connecting portion 126, 136 of generally conical shape, flared outwardly. The thickness of the walls of these connecting portions 126, 136 is reduced, so that these connecting portions 126, 136 form a kind of hinge allowing the securing portions 120, 130 to pivot relative to the base plate. 110. The two securing parts 120, 130 here comprise a succession of tubes 125, 135 of different diameters, which are cylindrical of revolution. Thus, these securing parts 120, 130 can here accommodate three kinds of ducts of different diameters. Each tube 125, 135 is equipped with its own fastening means 138 (see FIG. 19) with a routing sheath. These fixing means are here in the form of two diametrically opposite teeth 138, which project inside each tube 125, 135 and which are adapted to engage in one of the grooves of the corresponding duct . FIG. 20 shows in detail the cover 50 of the connector of FIG. 17. FIGS. 21 to 23 show an alternative embodiment of the electrical box of FIG. 1, which is specifically designed to cooperate with the connector of Figure 17. As shown in Figure 20, the cover 50 to snap over the partitions 20 of the base 10 of the connector of Figure 17 (to isolate the connecting elements) has a front wall 54 of square shape with rounded corners. This front wall 54 is bordered, at its four rounded corners, by flanges 55 extending parallel to and at the rear of the front wall 54. This front wall 54 is also flanked at its four straight edges. , four detent tabs adapted to hook to the base 10 of the connector of Figure 17. The front wall 54 further has three further openings 51, 52, 53 access to the output terminals of the connection elements. As shown in FIG. 21, the bottom 220 of the electrical box 200 has at least one access opening 221 to enable the electrical equipment to be connected to the connector 1. It here has a single access opening 221. whose edge has a shape identical to the mounting clearance, to the shape of the front wall of the cover 50. In this way, when the electrical box 200 is attached to the connector 1, the front wall 54 of the cover 50 comes closing this access opening 221. In the same way as for the electrical box of Figure 1, the access opening 221 is initially closed by a releasable cap 222 which has on the front face a tongue 223 facilitating its tearing. This cap 222 is overmolded on the body of the electrical box 200, in a softer material than that of the body of the electrical box, here in SEBS. In practice, this seal 222 is overmolded on the body of the electrical box 200 at the same time as the parallel flexible ribs 242 covering the flaps 241 of the electrical box 200 (see Figure 21). As is more particularly shown in FIGS. 22 and 23 (on which a central part of the lid 222 has been torn off to disengage the access opening 221), this lid 222 has a peripheral portion along the edge of the access opening 221, a bulge 224 which covers this edge. The peripheral portion of the cap 222 also has, along the edge of this bulge 224, a line of smaller thickness which facilitates tearing of the central portion of the cap 222 along this line. It is then observed in FIGS. 22 and 23 that when the central portion of the cap 222 has been torn off, only the bulge 224 remains. This bulge 224 will then have a sealing lip function, since it will be placed between the edge of the access opening 221 of the electrical box 200 and the edge of the front wall 54 of the cover 50. According to another variant of the invention not shown, it could have been provided that the shapes of the arms and their means of attachment to the wall are different from those of the arms and the attachment means shown in the figures. Thus, the arms could be slightly bent outward to generate a spring effect allowing them to cling more rigidly to the edge of the circular opening made in the plasterboard. According to another variant, the arms could be slightly bent at their centers inwards, so as to be able to pinch the electrical box when the latter is engaged in the wall. The attachment means could in turn be in the form of a single flexible layer overmolded on the outer faces of the arms, in which case the attachment of the connector to the wall would be by simple friction of this flexible layer against the edge the opening made in the plasterboard. The attachment means could also be formed by the arms themselves, provided that the arms are arranged in such a way that the installer is forced to bend them towards each other to engage the connector in the so that, when released, these arms are rigidly supported against the edge of the opening made in the plasterboard. The attachment means could also be in the form of snap tabs cut into the arms, which would cling to the back of the drywall when the edges of the legs would come to bear against the front face of the plasterboard. plasterboard. The attachment means could also be in the form of notches adapted to be anchored in the edge of the circular opening made in the plasterboard. Furthermore, if in the figures the inlet opening provided in the base for the passage of the electrical son has a closed contour, it could alternatively be provided that it has an open contour. It could thus be formed by a notch provided in the peripheral edge of the base, in which case the tracking sleeve would lock against the edge of this notch and would then be held in position by the bottom of the electrical box. FIG. 24 shows an alternative embodiment of the connector 1. In this variant, the connector 1 has a shape almost identical to that of the connector 1 of FIG. 17. It is distinguished from the latter only by the shape of its inlet opening 60. This inlet opening 60 here has an elongated rectangular shape along a portion of the perimeter of the peripheral rim 13 of the base 10. It has a first edge located at the level of the bottom wall 12 of the base 10. Its other three edges are bordered on the outside of the connector 1 by a flange 61. A groove 62 is recessed in the inner face of this rim 61. In FIGS. 25 to 28, there is shown a another embodiment of the tip 100, adapted to be fixed to the connector 1, in the axis of the inlet opening 60. In this embodiment, the tip 100 has three separate securing parts, which come in the form of three condu its 120, 130, 140 to accommodate the free ends of three different routing ducts 30. As shown in Figures 27 and 28, this tip 100 is formed of two half-shells 100A, 100B almost identical, equipped with latching means to allow their assembly. As shown in Figures 25 and 26, this tip 100 has a flexible portion, here made of SEBS, on which are molded rigid parts, here made of polypropylene. Thus, the mounting portion 110 of the nozzle 100 has, at its free end, a rigid sleeve 111B of rectangular section, which extends towards the conduits 120, 130, 140 by a flexible sleeve 111A. Similarly, each duct 120, 130, 140 includes a ring-shaped rigid collar 120B, 130B, 140B, which extends to the mounting portion 110 through a flexible tube 120A, 130A, 140A. Here, the ducts 120, 130, 140 form with the mounting portion 110 a cross. Thus, one of the conduits 130 extends in the axis of the mounting portion 110, while the other two conduits 120, 140 extend almost at right angles to them. These two ducts 120, 140 are here more precisely slightly inclined toward the first duct 130, at about 80 degrees with respect thereto.
[0026] The flexible tubes 120A, 130A, 140A of the conduits 120, 130, 140 then all communicate with the flexible sleeve 111A of the mounting portion 110. As shown in FIG. 25, the rigid sleeve 111B of the mounting portion 110 is lined, on three sides of its outer face, by a rib 112A which is adapted to slide in the groove 62 provided in recess in the flange 61 of the inlet opening 60 of the connector 1. Thanks to it, it is possible to report the tip 100 from the back of the connector 1, by sliding its rib 112A in the groove 62. To lock the tip 100 in position on the connector 1 when its mounting portion 110 is located in the axis of the inlet opening 60 of the connector 1, the rib 112A carries two ratchet teeth 113A adapted to be clipped into two notches 63 provided recessed in the inner face of the flange 61 of the inlet opening 60 of the connector 1 (see Figure 24). As shown in Figures 25 and 26, the duct 130, which is located in the axis of the mounting portion 110, here has a diameter greater than that of the other two ducts 120, 140, so that it can receive ducting ducts of larger diameters. In order to ensure a seal at the junction between the duct and the conduit in which it is introduced, the collar 120B, 130B 140B of each duct 120, 130, 140 is partially closed by a flexible annular membrane 120C, 130C, 140C . Each flexible annular membrane 120C, 130C, 140C here forms a planar washer which internally borders the free end of the conduit 120, 130, 140 corresponding and which is provided to deform when a sheath is threaded inside the conduit 120, 130, 140 corresponding. As shown in Figures 27 and 28, one of the half-shells 100A has latching lugs 101A adapted to snap on the other half-shell 100B.
[0027] It is here more specifically provided a latching lug 101A on either side of each half-collar 120B 130B, 140B and on either side of the rigid half-sleeve 111B of the first half-shell 100A. 101B arches are provided in correspondence on the other half-shell 100B, so that the latching lugs 101A can cross and clipped.
[0028] Since the ducts 120, 130, 140 are here partly rigid, they have a sufficient stiffness to ensure a good attachment of the ducting ducts to the nozzle 100. Since they are partially flexible, they allow the nozzle 100 to deform in order to facilitate the connection of the tracking ducts.
[0029] It is understood that when the tip 100 is deformed, the edges of the flexible parts of the two half-shells 100A, 100B may deviate from one another, creating gaps. This is the reason why, as shown in FIG. 27, the edge of the flexible part of the first half-shell 100A is extended by tongues 102A which are intended to be applied against the internal face of the flexible part. from the other half-hull 100B. Thus, when the installer deforms the tip 100, these tabs 102A close the interstices that are created between the edges of the flexible parts of the two half-shells 100A, 100B.
