Abstract
Abstract A power distributor device is disclosed for electric installations, comprising, for housing a set of power bars, an insulating case formed preferably of several interlockable modules. A member, for example an end-piece in the form of a lyre is associated with a zone for fixing the case on a support allowing expansion between the case and the support. An upstream connection box may be assembled to the case and comprise a zone for fixing to the support.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
203 words
An electric power distributor device for supplying low voltage apparatuses, comprising: a support member; an elongate insulating case of generally rectangular cross section, said case comprising at least two modular length sections and joining means interlocking said length sections in an end-to-end relationship, said case having a front face with a plurality of orifices regularly distributed on said front face, and an opposite face with first and second end regions, and fixing means securing said first and second end regions on said support member; a plurality of parallel power bars housed in said case along the length thereof; a plurality of input power supply conductors and an upstream connection box interlocked with an adjacent modular length section of the case, said connection box including said first end region of the case and housing clamping means connecting said input power supply conductors to one end of said power bars; a plurality of output conductors having terminations which pass through said orifices and connect said output conductors to said power bars; and an expansion absorbing end member having two portions movable relative to each other connected to said second end region of the case allowing relative heat expansion between the case and the support member.
Claim 2
Dependent Claim
203 words
An electric power distributor device for supplying low voltage apparatuses, comprising: a support member; an elongate insulating case of generally rectangular cross section, said case comprising at least two modular length sections and joining means interlocking said length sections in an end-to-end relationship, said case having a front face with a plurality of orifices regularly distributed on said front face, and an opposite face with first and second end regions, and fixing means securing said first and second end regions on said support member; a plurality of parallel power bars housed in said case along the length thereof; a plurality of input power supply conductors and an upstream connection box interlocked with an adjacent modular length section of the case, said connection box including said first end region of the case and housing clamping means connecting said input power supply conductors to one end of said power bars; a plurality of output conductors having terminations which pass through said orifices and connect said output conductors to said power bars; and an expansion absorbing end member having two portions movable relative to each other connected to said second end region of the case allowing relative heat expansion between the case and the support member.
Claim 3
Dependent Claim
62 words
A distributor device as claimed in claim 1, wherein the bars are flat and located in planes at right angles to said front face and said joining means consist of interlocking end portions of said length sections of the case, said end portions having surface portions parallel to said planes and engaging said bars and labyrinth-shaped further portions mutually engaging each other.
Claim 4
Dependent Claim
95 words
A distributor device as claimed in claim 1, wherein said expansion absorbing end member has first and second generally parallel wall portions at right angles to said front face, first joining means connecting the first wall portion to one modular length section at said second end region of the case and second joining means connecting the second wall portion to said support member, said first and second wall portions being mutually interconnected at a distance from said first and second joining means and having facing respective surface portions which form an expansion absorbing slit therebetween.
Claim 5
Dependent Claim
24 words
A distributor device as claimed in claim 1, wherein said first wall portion forms a closure of said case at said second end region.
Claim 6
Dependent Claim
65 words
A distributor device as claimed in claim 1, wherein each of said modular length sections comprises an insulating U-shaped cover provided with said orifices and an insulating base plate snap-fitted to said cover, said cover having grooves at right angles to said front face and having said bars and said base plate having ribs respectively engaging said grooves and holding said bars within said grooves.
Claim 7
Dependent Claim
132 words
A distributor device as claimed in claim 1, wherein each of said modular length sections comprises an insulating U-shaped cover provided with said orifices and an insulating base plate snap-fitted to said cover, said cover having grooves at right angles to said front face and having said bars and said base plate having ribs respectively engaging said grooves and holding said bars within said grooves and wherein said first joining means comprise a plate parallel to said front face and connected to said base plate of said one modular length section, means connecting said first wall portion to said cover of said one modular length section, said first wall portion and said plate having grooves housing said bars and said plate having ribs in alignment with the ribs of said base plate.
Claim 8
Dependent Claim
32 words
A distributor device as claimed in claim 1, wherein said output conductor terminations form part of a connector and said insulating case has polarizing means for preventing wrong mounting of said connector.
Claim 9
Dependent Claim
27 words
A distributor device as claimed in claim 7, wherein said polarizing mans include punch out caps provided in rows on the front face of the insulating case.
