Description

<Desc / Clms Page number 1>

 The present invention relates generally to electrical equipment designed to be mounted directly in a cable trough necessary for serving these equipment.

 It relates more particularly to an electrical assembly comprising an electrical apparatus and a cable routing chute, said electrical apparatus being able to be mounted directly on said chute by means of clipping means intended to cooperate with complementary clipping means provided on the chute.

 Such an electrical assembly is particularly advantageous because it allows easy mounting of the electrical apparatus in the chute without requiring any support and / or particular tools.

 However, the chute comprising two parallel lateral wings attached to a bottom wall has a certain flexibility, and, when the electrical equipment is mounted directly in the latter, said parallel lateral wings can deviate from one another to the detriment of the good performance of said electrical equipment.

 In addition, such a chute is generally closed by a cover which can fit into the longitudinal opening of the chute in which the various electrical devices are mounted.

 More particularly, sections of closing cover are cut on demand as a function of the location of the various electrical devices along the chute. The electrical equipment, usually not immobilized in the longitudinal direction of the chute, can then, after numerous connections and disconnections of the power cords of electrical devices to be connected to said electrical devices, create games between the latter and the sections of adjacent covers.

 Thus, foreign bodies, possibly metallic, can be introduced by these games inside the chute, which is not desirable.

 In order to remedy the aforementioned drawbacks, it has been envisaged to relate, adjacent to each mounted electrical appliance.

<Desc / Clms Page number 2>

 directly in the chute, a rigid immobilizing accessory which blocks said electrical apparatus in translation in the longitudinal direction of the chute, and which stiffens the lateral wings of said chute at the mounting of the corresponding electrical apparatus to avoid any separation of the latter during connections and disconnections on said electrical equipment.

 Such a immobilization accessory is described in document EP 0 844 714 belonging to the applicant.

 According to a fifth embodiment of the electrical assembly according to the invention shown in Figures 6 and 7, at least one longitudinal rib 24A, 24B projecting outwardly formed by at least one clip band 22A of the chute 11 comprises, for mounting an electrical apparatus, a projecting notch 25A, and the electrical apparatus 25 comprises, on the underside 38A of the front trim part 38, a groove 35B provided in correspondence with a recess 35A in which engages said notch 25A to form the anti-slip means.

 Here, each longitudinal rib 24A, 24B projecting outwardly formed by each of the clip bands 22A, 22B of the chute 11 has a plurality of notches 25A projecting as mentioned above.

 Each notch 25A has a width corresponding to the width of the corresponding recess 35A provided in the groove 35B of the electrical equipment 25. The electrical equipment 25 comprises, on each side of the front trim 38, on the underside 38A of this one, a recess

<Desc / Clms Page number 10>

 35A positioned approximately in a middle part situated between two clipping teeth 36 positioned on the corresponding side face 34.

 The distance P constituting the center distance of two successive notches 25A on an outer rib 24A of the chute 11 corresponds to the length of one side of the front trim part 38 of the electrical equipment 25 so that one can climb into the chute 11 a plurality of electrical devices 25 identical in contiguous fashion.

 According to a variant of the embodiment shown in FIG. 6, it can be provided that the electrical equipment 25 does not include the recesses 35A, but only the grooves 35B and that its front trim part 38 is inserted between two successive notches 25A provided on an outer rib 24A to block said electrical apparatus 25 in translation in the longitudinal direction of the chute 11. In this case, it is necessary that the distance m separating two successive notches 25A is equal to the length of one side of the part front cover 38A of the electrical apparatus 25, which bears on the end rib 24A comprising said notches 25A.

 However, according to this variant, the successive electrical devices mounted in the chute are no longer contiguous but separated from each other by the notches 25A, and it is then necessary to provide a shutter closing said chute at each notch 25A by masking this last and by establishing the junction between the end edges of two cover sections adjacent to said notch.

 According to another variant of the embodiment shown in FIG. 6, it can be provided that the electrical equipment 25 does not include the grooves 35B but only the recesses 35A, and each clip band 22A no longer forms the longitudinal rib 24A, 24B projecting outwards, but only the notches 25A extending towards the outside of the chute in the extension of the internal rib 23A, each notch 25A cooperating with a recess 35A of said electrical equipment 25 to form the anti-slip means .

<Desc / Clms Page number 11>

 According to the sixth and seventh embodiments of the electrical assembly according to the invention represented in FIGS. 8, 8a, 9 and 10, at least one of the reentrant longitudinal walls 20A of an end return 21A of a lateral wing 14A of the chute 11 comprises at least one hollow form 25A, here an opening, and the electrical equipment 25 comprises, in correspondence, on at least one lateral face of the front cover 38, a stud 35A projecting engaging in said hollow shape 25A to form the anti-slip means.

 As shown more particularly in FIG. 8a, each stud 35A extends from the lower edge of the front trim part 38, over a height H less than the height H ′ of the latter so that the upper edge of the stud 35A is set back from the upper edge 38B of the front trim 38. This shrinkage is equal to the thickness of the cover sections (not shown) for closing the chute 11, thereby avoiding "notching" the covers when the pad 35A is in the axis of the chute 11.

 The cover sections (not shown) closing the longitudinal opening 12 of the chute between the various electrical devices 25 mounted therein are thus well joined with the upper edges of the front trim parts 38 of said electrical devices 25 and come to bear on the upper edges of the studs 35A thus improving the resistance to sinking of said cover sections.

 According to the eighth embodiment shown in FIG. 11, at least one of the clipping bands 22A, 22B, and more particularly the inner rib 23A, 23B formed by it, comprises a notch 25A projecting with a width n equal at the expected distance between two clipping teeth 36 provided on the corresponding side face 34 of the electrical apparatus 25 so that, when the electrical apparatus 25 is clipped into the trough 11, said notch 25A is positioned in the spacing 35A between the two corresponding clipping teeth 36 by blocking the electrical equipment 25 in translation in the longitudinal direction of the chute 11. This cooperation of the notch 25A and the spacing 35A provided between two clipping teeth 36 of the electrical equipment 25 constitutes anti-slip means.

 Furthermore, for the electrical assemblies according to the invention represented in FIGS. 3, 4, 5, 6, 7, 9 and 10, the electrical apparatus 25 and the associated trough 11 further comprise recessed and / or projection of complementary shapes cooperating with each other to form anti-separation means of the lateral wings 14A, 14B of the chute 11.

 This is particularly advantageous because the natural flexibility of the chute 11 can lead, in the event of constraints, to a spacing of the lateral wings 14A, 14B thereof, that is to say to a widening of the longitudinal opening 12 , detrimental to the good performance of the electrical equipment 25.

 The anti-separation means aim to avoid this drawback.

 According to the embodiment shown in FIG. 5, the recessed and / or projecting arrangements 25A, 35A of complementary shapes forming the anti-slip means (described above) also form the anti-spreading means of the lateral wings 14A, Chute 14B 11.

 According to the embodiments shown in Figures 3,4, 6,7, 9 and 10, said anti-separation means comprise, on the one hand, on the chute 11, the ribs 24A, 24B projecting longitudinally outward of the chute 11, formed by the clipping bands 22A, 22B, at the end of the re-entrant longitudinal walls 20A, 20B corresponding to the end returns 21A, 21B of the lateral wings 14A, 14B of the chute, and, on the other part, on the electrical equipment 25, at least two grooves 35B, provided on the underside 38A of the front trim part 38, which run the length of two parallel sides of said electrical equipment, each groove 35B receiving one of said external longitudinal ribs 24A, 24B.

 As is more particularly shown in the figures, the electrical apparatus 25 comprises, on each of the sides of the front trim part 38, a groove 35B so that at each corner of the electrical apparatus two perpendicular grooves 35B intersect. The front bezel 38 then engages by its grooves 35B in the two parallel longitudinal grooves 26A, 26B defined between the outer ribs 24A, 24B, the longitudinal spacers to which they are attached and the re-entrant longitudinal walls 20A, 20B attached to the returns d end 21A, 21B of the lateral wings 14A, 14B of the chute 11.

<Desc / Clms Page number 13>

 Advantageously, the hollow and / or protruding arrangements of the chute 11 intended to cooperate with those of the electrical apparatus 25 to form the anti-slip and / or anti-separation means come from formation with said chute 11.

 For ease of implementation, these recessed and / or projecting arrangements forming the anti-slip and / or anti-separation means are produced symmetrically on one and the other of the lateral wings 14A, 14B of said chute 11.

 In addition, the recessed and / or protruding arrangements of the electrical apparatus 25 intended to cooperate with those of the chute 11 to form the anti-slip and / or anti-separation means come from formation either with the rear part of said apparatus. 25, either with the front bezel 38 of the latter.
