  • the object of the invention is essentially to remedy the aforementioned drawbacks and to design an electrical pipe of the aforementioned kind which better meets the various requirements of practice than known pipes, and which, in particular, can withstand pull-out forces without problem. transverse exerted on the cover, which lends itself to multiple combinations to allow the realization of all electrical supply schemes, which has a structure giving it an acceptable aesthetics, which can be produced by traditional techniques of plastic extrusion , and which is generally simple in structure, low cost and easy to install.
  • an electrical pipe according to the invention is characterized in that it comprises the combination of the provisions mentioned in the characterizing part of claim 1.
  • each conductive rail is enclosed in a box and is electrically isolated from the neighboring rail or rails and each box is mechanically closed. over its entire length on its two longitudinal edges.
  • the extraction forces of a removable connection element transversely to the pipe are distributed between the latching means so that the individual transverse forces exerted at each of said means are greatly reduced.
  • the cover can no longer deform (in particular bulge) significantly and there is no longer any risk of the cover becoming dislodged, as was, on the contrary, a common rule in prior devices.
  • the constants k and k o will be equal to 1/3 and 5/3 respectively.
  • the cover can only be fitted properly snapped onto the housing for one of the two positions in which it can be presented in front of the housing.
  • the latching means consist of projecting ribs with a beak-shaped section and delimiting shoulders extending respectively along the free edges of the side walls and internal partitions of the housing and along the wings facing the cover and on the housing and respectively on the lid, all the ribs are facing the same c * OTE except for a rib which is facing away from the other.
  • the housing and the cover can then be made of plastic and be extruded through dies of suitable shapes.
  • the rib turned away from the others is carried by one of the side walls of the housing and respectively by a wing situated along an edge of the cover.

  • Boxes of different dimensions, can be assembled edge to edge to obtain the number of boxes required, while these boxes can be coated with various covers, with or without conductive rails, to form electrical transmission lines or trunking intended to subsequently receive added wiring according to demand.
  • each conductive rail is offset with respect to the corresponding access slot
  • each conductive rail is positioned and retained in a gutter formed in a block with the cover and open on the corresponding access slot
  • Such an arrangement is added to those previously exposed to prevent incorrect coupling of component members.
  • This keying function can be further improved by using the fact that all the side walls and internal walls of the hooking ribs bearing housing facing the same c * Oté are doubled, the c * removed from the rib, of a stiffening wing extending opposite and at a distance from the hooking rib, said stiffening wing also constituting, in the configuration with offset rail, a keying stop preventing the penetration of the corresponding gutter into the corresponding box when the cover is not presented opposite the housing in said predetermined position.
  • each housing element has a longitudinal tongue located externally in the extension of the bottom of the housing, in order to identify a direction of installation of the housing, a tongue being manually cutable in particular to allow juxtaposition c * ote to c "ote at least two housings.
  • the height of this tab is between% and H, H being the depth of the pipe.
  • the cover To avoid incorrect placement of a removable connection element (in particular in the case where the number of conductive rails is two) and to avoid contacting non-couplable members, provision is made for the cover to have longitudinal deformation either male or female and closer to one of the longitudinal edges of the cover than the other, this deformation being intended to cooperate with a deformation of complementary shape (respectively female or male) of a removable connection element arranged to cooperate with the pipeline.
