    Electric box
    The present invention relates to an electrical box comprising a bottom wall and side walls projecting from a plane defined by said bottom wall, said housing comprising at least one cover and at least one mounting member attached to at least one two side walls of said housing, said at least one mounting member having a front face on which is attached a plug terminal block arranged to mount an electric meter, said at least one cover having at least one opening in which at least partially accommodates said at least one mounting member, said cover being detachably mounted and attached by means of angular fasteners to the electrical housing.
    Such an electrical box is known from DE 20 2009 003921. More particularly, the electrical box described in this document has a bottom wall and side walls projecting from a plane defined by said bottom wall, a cover and a mounting member, the cover having an opening in which is housed at least partially the mounting member. This type of housing is intended to be positioned and fixed on two support rails themselves attached to a wall. Many openings are provided in the bottom wall to allow the passage of electrical cables inside the housing to connect to various elements such as a pluggable terminal block. More specifically, this document discloses the positioning of a specific frame having special fastening sleeves for attaching a mounting member and having other particular fastening means for securing the cover with engaging sealing screws. in threaded holes in the frame walls.
    Unfortunately, with an electrical box as described in DE 20 2009 003921, it is necessary to proceed to the placement of a new frame (electrical box) specific that attaches to rails hung on the wall. Therefore, all elements forming an electrical installation already in place and which are mounted using support connected to these raiis hung on the wall must be dismounted before putting the frame in place and then back to the wall. inside these same elements. An adaptation of existing electrical systems is difficult or impossible, restrictive and requires time since it is necessary to proceed to a complete dismantling of the existing electrical instailation before reassembly inside the electrical box following its attachment to the rails wall mounted. The object of the invention is to overcome at least some of the drawbacks of the state of the art by providing a housing enabling the adaptation and reuse of existing electrical boxes (for example of the 25S60 type) by using existing fixing means. already at the level of the electrical box for fixing, at least one wall of said electrical box, said mounting member and said cover having at least one. opening, so that when the electrical box is opened by removing the cover, the mounting member remains in place even if the cover is removed. The objective is not to have to completely dismantle an electrical installation already in place before reassembling it in the electrical box but to propose an electrical box which adapts the existing electrical boxes by at least partially reusing them so that the equipment present inside an existing electrical box are not disassembled, easy access to these equipment is also preserved when the cover is removed.
    Another object of the present invention is to propose a solution that is both suitable for existing electrical boxes but also for new electrical boxes, in order to be able to keep the bottom wall and the side walls of an electrical box. already existing and for example fixed to a wall of a dwelling.
    To solve these problems, according to the invention, there is provided an electrical box as indicated at the beginning, characterized in that said cover and said mounting member are furthermore attached to the electrical box via at least one clamping member composed of a first member and a second member arranged to engage one another, said first member attaching said mounting member to a side wall of said housing and said second member allowing, by interlocking in said first member, to attach said cover to the same side wall of said housing.
    For the purposes of the present invention, the terms "angular fixing elements" are understood to mean fastening elements placed in the corners of the cover.
    Such an electrical box according to the invention makes it possible to adapt existing electrical boxes using the fastening means already present on the latter. Indeed, according to the invention, the cover is fixed at its corners by engaging the angular fixing elements in sockets already present at the corners of the existing electrical box. Furthermore, the fixation of the mounting member and the cover is also ensured by engaging, at the same socket already present in the existing electrical box (for example in a socket located substantially in the center of the electrical box along a side wall), at least one clamping element composed of a first member and a second member arranged to fit one into the other. Such a clamping element thus also engages in a means of attachment (socket) existing electrical box but further allows, according to the invention, the mounting member remains maintained in the electrical box even when the cover is removed for access the inside of the electrical box.
    Indeed, the first member of this clamping element attaches the mounting member to a side wall of said housing and the second member of this clamping member allows, by interlocking in said first member, to attach the cover to the same wall lateral of the case. When removing the cover, only the second member of the clamping element must be loosened, the first member of the clamping element still ensuring the maintenance of the mounting member. Indeed, according to the invention, the first member of the clamping element ensures the maintenance of the mounting member even when the second member of the clamping element is manipulated, for example unscrewed, so that it allows the detachment of the lid. An operator who wishes to detach the mounting member should proceed to a manipulation, for example unscrewing, of the first member of the clamping element, once the second member of the clamping member is no longer nested therein (or targeted).
    The electrical box according to the invention therefore makes it possible not to have to add fastening elements to the existing electrical box, which greatly facilitates its adaptation when the objective is to transform an existing electrical box into an electrical box according to the invention without having to disassemble the electrical equipment already present in the housing and without having to modify the structure of the existing electrical box, for example by adding fixing means as additional sockets. Indeed, the clamping element composed of a first member and a second member according to the invention is provided for fixing the mounting member and the cover by fixing in fixing means already existing at the housing electric. Similarly, the angular fixing elements engage in fastening means (sockets) already existing at the electrical box.
    Maintaining the mounting member and therefore the pluggable terminal, even when opening the housing, allows access to the inside of the casing without having to worry about maintaining the electrical meter connected to the pluggable terminal block and without having to separate these two elements. This makes it possible to easily replace one electric meter by another without having to modify the inside of the electrical box, that is to say without having to modify the element layout already present in said electrical box. Indeed, since the plug-in terminal block is mounted on a mounting member which is itself attached to at least two walls of the electrical box, it is therefore also secured temporarily or permanently with the electrical box. This means that when the cover or when elements or parts of the cover are removed, both the mounting member and the pluggable terminal block remain attached to the electrical box.
    Advantageously, this prevents any disconnection and manipulation of the electrical meter and / or the plug-in terminal block when intervention is necessary inside the electrical box, for example to replace or add an electrical component. Furthermore, since both the plug-in terminal block and the electric meter are located outside the electrical box, a replacement of one or both of these elements is easy and fast but also without risk for the operator not having to introduce your hands or tools into an environment containing live electrical cables. In addition, such a maintenance of the mounting member and therefore of the plug-in terminal block makes it possible to avoid any manipulation of the mains power supply cables which remain in place and remain connected to the plug-in terminal block.
    Advantageously, according to the invention, said cover is formed by a first cover member and a second cover member.
    Preferably, according to the invention, the cover has at least one sliding element arranged to slide inside said electrical box between a first position where an angular fixing element is accessible and a second position where the same angular fixing element is inaccessible, said sliding element being locked when positioned in said second position. This is particularly advantageous since the angular fixing elements, that is to say the fastening elements present at the corners of the lid, are rendered inaccessible, which prevents anyone from opening the electrical box easily. . Indeed, since the sliding element is in its locked position, it is no longer possible to easily access the angular fasteners, which makes it difficult to access the interior of the electrical box.
    For the purposes of the present invention, the term "locked" means that the sliding element is locked in a position which does not allow it to slide in either direction.
    Advantageously, according to the invention, said at least one sliding element has an end provided with a projection provided to ensure its locking when positioned in said second position.
    Preferably, according to the invention, said projection is arranged to ensure said locking by inserting into an orifice or abutting against another element of said electrical box. .
    Preferably, said orifice is formed in said mounting member. It is understood that any other orifice made at another location of the electrical box could also be suitable.
    Advantageously, said projection is arranged to ensure said locking by coming into abutment with an edge of a cover member. It is understood that any other part of the electrical box against which said projection could come into abutment is also suitable according to the invention.
    It could also be provided that the sliding element is provided with an orifice, which could engage a protrusion on an element of the electrical box, this engagement can ensure a lock.
    Advantageously, the electrical box according to the invention further comprises an intermediate frame interposed between side walls connected to said bottom wall and said cover. In this case, the mounting member and the cover are attached to the side walls of the electrical box which are those of the intermediate frame instead of those connected to the bottom wall. For the purposes of the present invention, the term "side walls" means both the side walls connected to the bottom wall and the side walls of the intermediate frame.
    Preferably, according to the invention, said at least one mounting member has a U-shaped longitudinal section. In this case the mounting member forms a kind of bridge attached to at least two side walls of said electrical box (as illustrated in Figure 1).
    According to an embodiment according to the present invention, said at least one cover is formed by a single cover member.
    According to another embodiment, said at least one cover is formed by a plurality of cover members, for example by two, three or four cover members.
    Advantageously, the electrical box according to the invention. comprises a plurality of mounting members, each mounting member being arranged to attach a plug-in terminal block arranged to mount an electric meter thereon.
    Preferably, according to the invention, said at least one cover has breakable parts arranged to allow the passage of electrical cables and / or the emergence of electrical equipment at the surface of the cover. Other embodiments of the electrical box according to the invention are indicated in the appended claims.
