- It relates more particularly to watertight electrical boxes to be protruding from wall walls, and electrical equipment provided with such an electrical box.
- a cable gland for an electrical box comprising:
- a support plate made of a rigid material, which has a substantially planar face and which has at least one cable passage opening, and
- a seal made of a flexible material which extends around said opening to provide a seal between the support plate and the rest of the electrical box.
- An electrical box typically has a rear case and a front frame for snapping onto the rear case. These boxes are then designed to receive mechanisms such as socket or switch mechanisms or even detectors.
- the rear housing then has recessed notches in its front edge, designed to receive these cable gland end pieces, which end pieces have a pierceable cover for the passage of a cable.
- the aim of the present invention is therefore to provide a new cable gland end piece which has one and the same seal capable of ensuring good sealing between the various components of the box.
- a cable gland end piece is proposed as described in the introduction, in which the seal comprises a main part with a closed contour which extends entirely over said substantially planar face of the support plate.
- the seal is not provided on the outer peripheral edge (that is to say on the edge) of the support plate of the cable gland end piece, but rather on one of the faces of this end piece.
- the support plate being preferably intended to be attached by a sliding movement in grooves located recessed in the front and rear parts of the electrical box, the seal is provided to engage in these grooves, by compressing between the support plate and one of the edges of each groove.
- the cable gland can be easily extracted from the electrical box, which facilitates the fixing of the rear part of the box to its support and which also facilitates the insertion of the electrical conductors through. of this tip.
- said seal has a uniform cross section along the entire closed contour;
- the support plate has an outer peripheral edge and the main part of the seal extends at a distance from said outer peripheral edge;
- said seal comprises two bulges which are located at a distance from each other and which each extend at least in part on said substantially planar face, between the main part and the outer peripheral edge of the wafer; support;
- the two bulges extend from the main part to the outer peripheral edge of the support plate, over at least part of the thickness of the support plate;
- the main part forms a ring or a lip

- a rear part comprising a bottom wall provided with means for fixing to a receiving support and a side wall bordering said bottom wall, and
- a front part comprising a side wall attached to said rear part so that the side wall of the front part extends in the extension of the side wall of the rear part and defines therewith a housing adapted to receive a mechanism of electrical equipment, in which said side walls comprise, recessed in their edges, notches facing each other which receive a cable gland end piece as mentioned above.
- Each side wall comprises, along said notch, a wall element and a flange which together define a receiving groove for the cable gland end piece;
- the wall element and said rim extend outside said notch to together define a groove for engaging the edge of the other side wall;
- the front and rear parts are snap-fastened together.
- the notches provided opposite each other in the front part and in the rear part of the box to accommodate the cable gland end piece each define a groove for receiving the edge of the cable gland end piece. The continuity between these two receiving grooves then facilitates the sealing of the connection between the different parts of the box.
- the invention also relates to an electrical device comprising an electrical box as mentioned above, an electrical device mechanism received in the housing delimited by the side walls of said electrical box, and a cover which closes said electrical box at the front.

For this it follows a generally rectangular contour, in particular square, with straight panels 215A, 215B connected by angled portions forming corners with cut angles, in correspondence with the contour of the side wall 110 of the support plate 100.
- An extension 220 in the form of a frame of lower height is attached by fitting onto the front edge of the frame 200.
- the frame 200 is produced by the association by clipping of the sleeve formed by the side wall 210 and of the extension 220.
- the extension 220 has four clips arranged at the four corners, which are housed in correspondingly shaped housings provided at the four corners of the frame 200.
- This extension 220 has an aesthetic and protective function. It is in fact designed to receive the trim 30 internally.
- the frame could be made in one piece, for example of molded plastic.
- the frame 200 has on the inner face of its side wall 210 holes 221 for fixing the cover 30. These holes 221 are adapted to receive elements allowing mounting the cover 30 on the frame 200. These mounting elements (not visible) are for example quarter-turn elements, operable from the front face of the cover 30.
- the side wall 210 of the frame 200 has, on two opposite right panels 215A extending in the extension of the opposite right panels 115A of the side wall 110 of the support plate 100, a determined and uniform maximum height H2.
- this side wall 210 decreases locally, from the maximum height H2, up to 'at a minimum height h2.
- This minimum height h2 is for example less than or equal to 20% of the maximum total height H3 of the electrical box 10 (FIG. 2).
- This local decrease in height in the side wall 210 forms a notch 211 which delimits said second inlet opening portion 211.
- two notches i.e. two second entry opening portions 211, are formed on the opposite right panels 215B of the side wall 210 of the frame 200.

- This compression of the seal 320 is therefore carried out during the installation of the cable gland end piece 300 in these receiving grooves 114, 214. Its compression is therefore independent of the force with which the plate -support 100 and the frame 200 are brought into contact with one another.
- the main part 321 of the gasket 320 has a uniform cross section along the entire closed contour of the gasket. It forms here a quasi-circular ring, the cross section of which is half-disc. Alternatively, it could form a lip.
- the closed contour defined by the seal 320 is here qualified as “quasi-circular” in the sense that it may have, as is the case here, a rectilinear portion to follow the shape of the inner peripheral edge 313 of the support plate 310.

- This flange 252 comprises a slot 253 into which the end of a tool such as a screwdriver can be inserted, for example to disengage the notch 150 of the lever 250 in order to release the lever 250 (and therefore detach the attachment means of the frame 200 from that of the support plate 100).
- the installer first fixes the support plate 100 on the wall by inserting screws into the oblong holes 128 (figures 2, 4 and 5) and adjusting its orientation. It optionally also introduces screws through the circular holes 127 to stiffen the fixing.
- the installer introduces an electric cable or an electric sheath through the waterproofing membrane 330; 340 of the cable gland 300 then inserts the support plate 310 of this cable gland 300 in the groove 114 formed in the side wall 110 of the support plate 100, along the first opening portion d 'entry 111.
- the installer then cables the electrical equipment mechanism 20 and then positions it on the uprights 120 of the support plate 100.
- the installer assembles, on the support plate 100, the frame 200 provided with its extension 220, by interlocking thanks to the complementary assembly means and by snap-fastening thanks to the means of 'complementary attachment.
- the installer mounts the cover 30 in the openings 221 of the side wall 210 of the frame 200 in order to hermetically close the front opening of the electrical box 10 and to give its function to the electrical equipment 1.
- the electrical box has a section of square shape and it defines a single station making it possible to accommodate one or two electrical equipment mechanisms: this is said to be a single station box.
- the electrical box could be a multi-station box, having a section of rectangular shape and defining two or three stations.
- the electrical box will preferably include a frame defining several openings, each being intended to receive a station.
