Abstract
A busbar device with an insulating support block with two assemblable fixing parts bounding internal housings to receive multipole current conductors, each housing being formed by a semi-open recess. The bottoms of the recesses are located in distinct planes extending in a parallel manner along the longitudinal direction of the profiled sections, and separated from one another by a predetermined transverse pitch, and the profiled sections of the current conductors are staggered at regular intervals in the extension direction of the assembly interface of the fixing parts to form a stepped structure.
Claims11
A busbar device for an electrical power supply and/or distribution installation, comprising:
- current conductors formed by elongated profiled sections comprising electrically conducting material and having a C-shaped cross-sectional portion;
- at least one insulating support block comprising a first fixing part engaged with a second fixing part at an assembly interface to constitute a plurality of individual housings each to receive an individual current conductor, said insulating support block extending perpendicularly with respect to a longitudinal direction of the profiled sections;
- semi-open recesses formed in one of at least the first and second fixing parts to bound said housings, said recesses having bottoms located in distinct planes extending in a parallel manner along the longitudinal direction of the profiled sections, and separated from one another by a preset transverse pitch, said profiled sections being staggered at regular intervals with respect to the assembly interface to form a stepped structure;
- and
- assembly means for tightening the first and second fixing parts against one another at the assembly interface,
- wherein said C-shaped cross-sectional portion comprises a flat contact face to which a connecting conductor is connected outside the insulating support block, connection being made in a predetermined longitudinal position by means of a connecting device having a bolt and nut accessible from outside, each contact face being arranged in a plane parallel to a direction of the transverse pitch, and staggered transversely by the transverse pitch, and along the assembly interface by said intervals,
- wherein the current conductors further comprise a U-shaped cross-sectional portion extending opposite to an open area of the C-shaped cross-sectional portion, and
- wherein the width of each recess, measured from the contact face in the direction of the assembly interface, corresponds to the width of the current conductors.
