    [0001] TECHNICAL FIELD TO WHICH THE INVENTION RELATES The present invention relates generally to electrical equipment to be engaged in electrical boxes which are for example embedded in walls or ceilings. It relates more particularly to an equipment module for engaging in an electrical box, comprising a housing made of insulating material which delimits an interior receiving space of an electrical mechanism, and latching means which are adapted to ensure the fixing of the box in the electrical box and which comprise: - a hooking part adapted to hook to said electrical box, - a tab which carries said hooking portion and which is flexible between a rest position and a deformed position, and Means for actuating said tab, which are accessible to the user by the front of said box. The invention finds a particularly advantageous application in the production of an equipment module having, for example, a switch function, a reciprocating function, an electric dimmer, a power socket, a network plug (RJ45). , telephone jack (RJ11), VDI or equivalent (HDMI, ...), indicator, thermostat, or detector (smoke, flood, temperature, movement, brightness or light). TECHNOLOGICAL BACKGROUND Currently, electrical equipment generally has similar architectures, with a frame-shaped equipment carrier to be attached to the front of an electrical box, an equipment mechanism (for example, a control mechanism). switch or receptacle) to be locked in the opening defined by the equipment support, and a finishing plate (or "trim plate") to be fixed on the equipment support in such a way that it hides the latter and aesthetically borders the fitting mechanism. The equipment mechanism comprises in particular an insulating base which houses connection terminals for its connection to the local electrical network and which is closed at the front by a hubcap accessible to the user (a tilting or sinking key in the case of a switch or a back and forth, a connection well in the case of a socket, ...). This insulating base is generally snapped, usually permanently, into the equipment support, while the equipment support is fixed to the electrical box by means of screws whose heads rest on the equipment support and whose the threaded bodies are screwed into screwing wells provided in correspondence in the electrical box. Therefore, when the user wishes to replace the fitting mechanism by an optimized mechanism, it is forced to unscrew the screws that hold the equipment support on the electrical box, to remove the equipment support, to replace it by another equipment support carrying the new fitting mechanism, then screw the screws, which is tedious and expensive. Mechanisms are also known whose insulating bases can be released from the equipment supports in which they are snapped.
    [0002] However, the extraction of the insulating base requires the use of a tool, so that this operation is tedious. Document DE9106123 discloses an electrical apparatus comprising an equipment module to be housed in an electrical box. As it appears in this document, the equipment module comprises a base flanked by two flexible tabs which extend from the base of the base to the front and which have snap teeth provided to hang on to Windows made in the electrical box. The flexible legs are also each equipped with a lever. This lever allows the user to force, using a screwdriver, the flexible tab to bend inwardly to disengage its detent tooth from the window in the electrical box. A disadvantage of this equipment module is that its extraction out of the electrical box is difficult to implement, especially since it requires several tools.
    [0003] Indeed, to simultaneously release the two flexible legs out of the windows in the electrical box, the user must, firstly, use two screwdrivers to flex simultaneously the two flexible tabs, and, secondly, exercise a tensile force on the equipment module to extract it from the electrical box.
    [0004] OBJECT OF THE INVENTION In order to overcome the aforementioned drawback of the state of the art, the present invention proposes an apparatus module as defined in the introduction, in which there is provided means for retaining the tab. in deformed position. Thus, thanks to the invention, the tab can be placed in one or the other of two stable positions: either in the rest position or in the deformed position. Consider, for example, the case where the latching means are shaped in such a way that, when the tabs are at rest, the detent teeth cling to the electrical box. It is then possible to easily remove the equipment module out of the box by successively forcing the tabs to bend in deformed position (position in which they are blocked by the retaining means), then exerting a tensile force on the module fitting. It will be understood that the user can extract the equipment module from the electrical box with one hand. Preferably, the rest position of the tab is located towards the outside of the housing relative to the deformed position. The invention also relates to a method of extracting an equipment module 20 as mentioned above from an electrical box, comprising the steps of: - operating the operating means of each tab to move each tab in the deformed position such that the retaining means holds each tab in the deformed position, and then pull the casing out of the electrical box. Other advantageous and non-limiting characteristics of the equipment module according to the invention are as follows: said holding means come from forming in one piece with the housing; There is provided a front plate to be brought to the front of said casing and said retaining means come in one-piece formation with said front plate; - said retaining means are adapted to cooperate by snapping with said tab; said retaining means comprise a tongue to which is adapted to clip a hook which projects from one of the faces of said tab; said operating means are accessible to the user by the front of said housing; at least two latching means are provided, which are regularly distributed around the periphery of the housing; and the attachment portion of at least one of the latching means comprises means for angularly locking the housing in said electrical box.
    [0005] DETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT The following description with reference to the accompanying drawings, given as non-limiting examples, will make it clear what the invention consists of and how it can be achieved. In the accompanying drawings: - Figure 1 is a schematic exploded perspective view of an equipment module according to the invention and an electrical box adapted to receive this equipment module; FIGS. 2, 3 and 4 are respectively views of details II, III and IV of FIG. 1; FIGS. 5 and 6 are cross-sectional views of part of the switchgear module engaged in the electrical box of FIG. 1, in which a tab of the switchgear module is respectively shown in the deformed position and in the rest position. . FIG. 1 shows, on the one hand, an equipment module 30 which includes a trim 70 and, on the other hand, an electrical box 50 intended to receive the equipment module 30 and to be fixed to a wall. In this case, this electrical box 50 is of the type to be embedded in a cavity made in a wall. This wall is here formed by a hollow partition. It is recalled in this regard that, in known manner, such a hollow partition 30 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. The cavity formed in this hollow partition to accommodate the electrical box 50 is then simply formed by a circular opening made with a hole saw in one of the plasterboards. In the description, the terms "front" and "back" will be used relative to the gaze direction of the installer of the fitting module 30 in the plasterboard. Thus, the terms front and rear respectively designate the outwardly facing location of the hollow partition and the inwardly facing location of this hollow partition. The electrical box 50 here comprises a side wall 51 closed at the rear by a bottom wall 52 for delimiting a receiving housing of the equipment module 30.
    [0006] As shown in FIG. 1, this equipment module 30 is in the form of a "all-in-one" block, adapted to be attached directly to the electrical box 50 (without using an equipment support to make the connection between the switchgear module and the electrical box). The equipment module 30 comprises a housing 31 of insulating material which is intended to be entirely housed in this housing. It also comprises at least one front plate which covers the casing aesthetically. This housing 31 is more specifically here intended to be covered by two front plates, including a central trim 70 and a peripheral trim plate (not shown). The equipment module 30 is designed to offer the user the desired electrical function (socket, switch, ...). The housing 31 of the equipment module 30 has for this purpose a side wall 33 defining an interior receiving space of an electrical mechanism 32. The equipment module 30 is also equipped with at least one locking means 40, 45 for fixing the housing 31 in the electrical box 50. It will be preferred that the equipment module 30 comprises at least one pair of latching means 40, 45. As shown in FIG. 30 of equipment has two pairs. Each of these latching means 40, 45 comprises a tab 41, 46 which is flexible between a rest position and a deformed position (here, this position is deformed towards the inside of the housing). This lug 41, 46 is here cut into the side wall 33 of the housing 31 so that in the rest position, each lug 41, 46 extends in the extension of the side wall 33 of the housing 31. Each lug 41, 46 door, side of its free end, a hooking portion 42, 47 adapted (here, when in the rest position) to hook to the electrical box 50. Each leg 41, 46 is also equipped maneuvering means 43, 48 which allow the installer to move it in the deformed position. According to a particularly advantageous characteristic of the invention, the equipment module 30 comprises retaining means 39 adapted to retain at least one of said tabs 41 in the deformed position. In practice, here, the retaining means 39 can hold two of the four tabs 41 in the deformed position. The deformed position of each tab 41 being located towards the inside of the casing 31 with respect to the rest position, these retaining means 39 thus make it possible to hold each lug 41 in a position in which the gripping portions 42 do not prevent not the extraction of the housing 31 out of the electrical box 50. In this way, when he wants to engage or extract the housing 31 in or out of the electrical box 50, the installer can block these two tabs 41 41 in the deformed position , and then easily maneuver the two other tabs 46 to move the casing 31. In the embodiment of the invention shown in Figure 1, the side wall 33 of the housing 31 is cylindrical in revolution about an axis Al. is partially closed at the front by a flat front wall 34 (which has in its center a clearance to accommodate the hubcap 70). It is also bordered at the front by a peripheral sidewalk 38 provided to bear against the front edge of the electrical box 50. The shape of the housing 31 is designed to be similar to that of the interior volume delimited by the electrical box 50 The shape of this housing 31 thus makes it possible to take advantage of the entire interior volume delimited by the electrical box 50 to accommodate electrical mechanisms of all sizes. The electrical mechanism 32 housed inside the casing 31 conventionally comprises a functional part serving to perform the function for which the fitting module has been designed, and a connecting part serving to ensure its electrical connection to the local electrical network. By "functional part" is meant a part that is adapted to perform a function that goes beyond a simple connection to electrical conductors (this connection being made by the "connecting part").
    [0007] The functional portion has a shape adapted to the function that the electric mechanism must perform. It can thus be an interaction function with the installer (typically a socket function, switch, back and forth, dimmer, VDI socket or equivalent, network socket, telephone jack), or an interaction function with the environment (typically a function of indicator, thermostat, smoke detector, flood detector, temperature detector, motion detector, light detector or brightness detector ...). This is a plug function.
    [0008] The functional part then comprises an earth pin 35, and two cells (not visible) which are housed inside the housing 31 and which are adapted to receive two pins of an electrical plug. The connection part may in turn have automatic or screw terminals, for fixing and connecting three electrical son from the local electrical network to the aforementioned earth pins and cavities. The hubcap 70 is then adapted to be attached to the front of the housing 31, in the recess provided in the center of the front wall 34 of this housing 31, so that it allows access to the functional part of the housing. electric mechanism 32.
    [0009] This hubcap 70 thus comprises a front wall 71 having a hollow recess towards the rear which delimits an insertion well of the electrical plug. Its front wall 71 is flat here and has an annular shape. The insertion well is more precisely delimited by a cylindrical side wall 72 of revolution about the axis A1, which is closed at the rear by a bottom 73 in which there are three openings for the passage of the spindle. 35 and the passage of the pins of the electrical plug. For attaching the hubcap 70 to the housing 31 of the equipment module, the side wall 72 of the hubcap 70 externally carries ratchet teeth (not visible) adapted to engage the housing 31.
    [0010] As shown in Figure 1, the tabs 41 of the two latching means 40 of the housing 31 in the electrical box 50 are here diametrically opposite to the axis Ai, and extend in length parallel to the Al axis.
    [0011] As shown in Figure 3, each tab 41 has a rectangle shape with three of the edges are free and whose fourth edge, namely here the rear edge is connected to the side wall 33 of the housing 31 to form a kind of hinge . As mentioned above, each lug 41 carries an attachment portion 42 for attachment to the electrical box 50. This attachment portion is here in the form of a retaining tooth 42 which extends in length parallel to the front edge of the tab 41. Each retaining tooth 42 has a flat front face orthogonal to the axis Ai, which is adapted to hook to the electrical box 50, and a rear face inclined relative to the Ai axis, which forms a ramp allowing the tab 41 to elastically deform inwardly of the housing 31 when the equipment module 30 is reported in the electrical box 50. Here, the tabs 41 extend beyond these retaining teeth 42 and rise beyond the front wall 34 of the housing 31, so that their free ends 43 before are accessible. In this way, these free ends before 43 form said operating means, which allow the installer to manually bend the tabs 41 inwardly of the housing 31 to extract the equipment module 30 out of the electrical box 50. The retaining means 39, which make it possible to retain each tab 41 in deformed position, could be located on the trim 70 (for example at the rear of its front wall 71) or on the trim plate. Here, as shown in Figures 5 and 6, these retaining means 39 are located on the housing 31. They are more precisely formed in one piece with the housing 31. Otherwise formulated, the housing 31 being molded of a single part of insulating material (here ABS), these retaining means 39 are formed at the time of molding of the housing 31. These retaining means 39 are adapted to cooperate by snapping with the legs 41. In this case, these retaining means comprise two tongues 39 which extend from the rear face of the front wall 34 of the housing 31, towards the rear, respectively opposite the two tabs 41. Each tab 41 then comprises, projecting from its inner face, a hook 44 which automatically clings to the corresponding tab 39 of the housing 31 when the installer forces this tab 41 to flex to its deformed position. The hooks 44 and the tongues 39 are shaped such that they can retain the tabs 41 in the deformed position but, if the installer exerts on the tabs 41 a force towards the outside of the casing 31, they release the tabs 41 so that they return elastically in the rest position. The hooks 44 and the tongues 39 are further shaped to make a snap when they hook together, allowing the installer to check that they have hooked up properly. As shown in Figure 1, the other two tabs 46 of the housing 31 have different shapes from those of the tabs 41 described above. These lugs 46 are more precisely designed to allow the housing 31 to be locked in position angularly about the axis Al relative to the electrical box 50. As shown in FIG. 1, these two lugs 46 are located diametrically opposite each other. relative to the axis Ai, at equal distances from the first legs 41, and they extend in length parallel to the axis Ai. As shown in FIG. 2, each tab 46 has a rectangle shape, three of whose edges are free and whose fourth edge, namely here the rear edge, is connected to the side wall 33 of the casing 31 to form a kind of hinge. As mentioned above, each tab 46 carries a hooking portion for attachment to the electrical box 50. These attachment portions are formed by notches 47, here three in number by 46 tab. 30 These notches 47 are located projecting from the outer face of the corresponding tab 46, side-by-side along the front edge of this tab 46. Each notch 46 has an outwardly protruding shape (here triangular), with two straight lateral edges in dihedron, a plane front face orthogonal to the axis A1 and a rear face inclined with respect to the axis Al (which forms a ramp allowing the tab 46 to deform elastically inwards when the fitting module 30 is reported in the cylindrical box 50). Here, the tabs 46 extend beyond these catches 47, towards the inside of the casing and towards the front, so that their front free ends 48 rise beyond the front wall 34 of the casing 31 and are easily accessible. In this way, these free ends before 48 form said operating means, which allow the installer to manually bend the lugs 46 inwardly of the housing 31 to pivot the housing 31 in the electrical box 50 or to extract the housing 31 out of the electrical box 50.
    [0012] In FIG. 1, it can be observed that the electrical box 50 consists of a body 50A made of a rigid plastic material (typically made of polypropylene) and a coating 50B made of a softer material (typically in SEBS). "Polystyrene-b-poly (ethylenebutylene) -b-polystyrene").
    [0013] The side wall 51 of the body 50A of the electrical box 50 has a cylindrical shape of revolution about the axis A1. In FIGS. 1 and 4, it can be seen that the electrical box 50 has, for fixing the module housing. apparatus 30, four windows 60 evenly distributed about the axis Al.
    [0014] These four windows 60 are identical. They each have a rectangular shape and they extend in length along the front edge of the side wall 51 of the electrical box 50. They have a height sufficient to allow the engagement of the retaining teeth 42 or notches 47 of the housing 31 of the equipment module 30. They are through, in that they open on either side of the body 50A of the electrical box 50. As shown in Figure 1, the coating 50B covers here a large part of the outer face of the side wall 51 of the body 50A of the electrical box 50, so that it closes the bottoms of the four windows 60.
    [0015] This coating 50B is here drilled, at each window 60, two openings 61 located at a distance from one another. The retaining teeth 42 of the casing 31 of the equipment module 30 are adapted to catch at the front edges of two of the windows 60 when the peripheral sidewalk 38 of the casing 31 bears against the front edge of the side wall 51 of the electrical box 50, which allows to block the equipment module 30 axially (along the axis Ai). Here, the notches 47 of the equipment module 30 are also adapted to hook to the front edges of the two windows 60 when the peripheral sidewalk 38 of the housing 31 bears against the front edge of the side wall 51 of the electrical box. 50, which allows them to participate in the axial blocking of the equipment module 30 in the electrical box 50. The retaining teeth 42 and the notches 47 extend here over the entire width of the tabs 41, 46 which carry them. The widths of these lugs 41, 46 are strictly smaller than the lengths of the windows 60. Therefore, once the retaining teeth 42 and the notches 47 hooked to the front edges of the windows 60, the equipment module 30 remains free to pivot in the electrical box 50 around the axis Ai. Of course, this pivoting is bounded between two extreme angular positions in which the edges of the retaining teeth 42 come into contact with one or other of the ends of the corresponding windows 60. To block this pivotal mobility, the notches 47 cooperate with the part of the coating 50B which closes the bottom of the windows 60 to which the notches 47 hook. To ensure an effective cooperation of these notches 47 with the coating 50B, it is possible to provide abutments (not shown and coming for example from formation with the trim plate) to force the tabs 46 to bend outward, so that the notches 47 are anchored in (or pierce) the coating 50B. The use of these stops will be described in more detail later in this discussion. For fixing it in the circular opening made in the plasterboard, the electrical box 50 has an external sidewalk 58 which runs along the edge of the front opening of its side wall 51 and which is adapted to bear against the front face gypsum board, all around the circular opening that is practiced there. Thus, this outside sidewalk 58 can block the electrical box 50 backwards. For its blocking forward, the electrical box 50 could be equipped with two claws which would intervene in diametrically opposite position and which, under the control of screws, would be able to hook onto the rear face of the plasterboard. Here, as shown in Figure 1, the side wall 53 of the electrical box 50 has four generally rectangular flaps 56 which are cut into openings 54 formed in the side wall 51 and which are regularly distributed around the axis Al. Each flap 56 has three free edges and a fourth edge, namely here the front edge, which connects to the rest of the side wall 51 by two hinge tabs. The flaps 56 are thus free to pivot through the openings 54, between a retracted position and an extended position.
    [0016] At rest, the flaps 56 are in the retracted position, that is to say that their outer faces are located in the extension of the outer face of the remainder of the side wall 51 of the body 50A of the electrical box 50. These flaps do not thus do not interfere with the engagement of the electrical box through the circular opening made in the plasterboard.
    [0017] These four flaps 56 each comprise, projecting on their inner faces, two parallel ribs 57 which form ramps of axes parallel to the axis A1. Thus, when the equipment module 30 is attached to the electrical box 50 according to the Ai axis, its housing 31 bears against these parallel ribs 57, which allows to force the flaps 56 to deploy in the extended position, that is to say projecting from the outer face of the side wall 51 of the body 50A of the electrical box 50. Here, the coating 50B covers including the flaps 56 so as to close the openings 54. It has, at each of the flaps 56, ribs 59 parallel to the axis Ai, projecting on its face external.
    [0018] In this way, when they deploy, the flaps 56 compress the ribs 59 of the coating 50B against the edge of the circular opening made in the plasterboard, which allows the electrical box 50 to be fixed in this circular opening. The trim plate (not shown) is for its part adapted to be attached to the front of the housing 31, around the hubcap 70, for aesthetic purposes and electrical protection. For attachment to the front of the fitting module 30, the trim plate has four toothed tabs which extend from its rear face, rearwardly.
    [0019] Correspondingly, as shown in Figure 1, the front wall 34 of the housing 31 has four slots 37 regularly distributed about the axis Ai, through which the notched lugs of the trim plate can engage and hook at the desired height.
    [0020] Installation of the equipment module 30 in the circular opening made in the plasterboard of the hollow partition is then performed as follows. The installer first reports the electrical box 50 in the circular opening, taking care that its outer sidewalk 58 is applied against the plasterboard. The installer then returns the equipment module 30 in the electrical box 50, taking care that its peripheral sidewalk 38 is applied against the outside sidewalk 58 of the electrical box 50. The equipment module 30 being delivered in a configuration where its tabs 41 are retained in the deformed position (see Figure 5), the retaining teeth 42 do not form an obstacle to this commitment. During this engagement, the flaps 56 of the electrical box 50 are pushed outwardly by the housing 31, so that the electrical box 50 is then rigidly attached to the plasterboard.
    [0021] Once the equipment module 30 is engaged in the electrical box 50, the notches 47 of the housing 31 automatically cling to the windows 60 of the electrical box 50, which makes it possible to retain the equipment module 30 axially in the electrical box. 50. In the absence of the trim plate, the notches 47 are simply resting against the coating 50B of the electrical box 50, so that they weakly block the equipment module 30 in the angular position in the electrical box 50. To adjust the angular position of the equipment module 30 in the electrical box 50 about the axis A1 (in order to orient the fitting module 30 vertically above the vertical of the hollow partition), the The installer may force the switchgear module to rotate. It can otherwise manipulate the free ends before 48 tabs 46 so as to move the notches 47 of the coating 50B, before rotating more easily the equipment module 30. The installer then forces the tabs 41 to return to the rest position , so that the retaining teeth 42 also cling to the edges of the windows 60 of the electrical box 50, which improves the axial blocking of the equipment module 30 in the electrical box 50 (see Figure 6). Finally, the installer reports the trim plate to the front of the housing 31, so that its toothed tabs cling to the slots 37 provided in the front wall 34 of the housing 31. In this position, the free ends before 43, 48 tabs 41, 46 are hidden and are no longer accessible. In this position also, the abutments possibly provided at the rear of the trim plate push tabs 46 outwards, so that the notches 47 are firmly anchored in the coating 50B of the electrical box 50 (this which ensures effective angular blocking of the equipment module 30 in the electrical box 50). To extract the equipment module 30 out of the electrical box 50, the installer proceeds as follows. He begins by removing the trim plate, so as to discover the free ends 43, 48 of the tabs 41, 46 of the housing 31 and release the notches 47. It then maneuvers the free ends before 43 of the tabs 41 to 20 forcing the latter to bend in the deformed position, so that their hooks 44 cling to the tongues 39 of the housing 31 (see Figure 5). With one hand, the installer can then pinch the free ends before the legs 46, so as to extract the notches 47 of the windows 60 of the electrical box 50, which allows the module to be removed. Apparatus 30 out of the electrical box 50. The present invention is not limited to the embodiment described and shown, but the skilled person will be able to make any variant within his mind. It would thus be possible to equip all the tabs (41, 46) of the equipment module 30 with hooks, so that the installer can block all these tabs in the deformed position. According to another variant of the invention not shown in the figures, it could have been provided to mold the housing of the equipment module such that at rest, the tabs (41) are inclined towards the inside of the housing. In this variant, the retaining means would then be designed to retain the legs in the upright position (in the extension of the side wall of the housing). Otherwise formulated, at rest, the teeth of the legs could not cling to the electrical box. It would then bend the legs outward, in the upright position (position in which they are held), so that the teeth of the legs can cling to the windows of the electrical box. According to another variant of the invention not shown in the figures, it could have been provided that the retaining means are formed by latching claws coming from formation with the casing, in which case these latching claws would be adapted to hook the latches. legs (41) by their slices or by their free ends. According to another variant of the invention, it could have been provided that the retaining means are not formed with the housing, and that they are mounted movably on the housing. Each retaining means could then be in the form of a latch movably mounted in translation or rotation on the housing, between a first position in which it would leave the leg free of its movements and a second position in which it would hold the leg in deformed position.
