Abstract: This system for electrically connecting and fastening at least one plate-type electrical conductor to a support piece provided with a nut designed to cooperate with a fastening screw of the conductor is characterized in that an annular spacer of electrically conductive material is joined to support piece on the side of this piece that is facing the conductor and in that nut is disposed on the other side of the support piece opposite this spacer and is connected to this spacer by floating coupling means designed to extend through a corresponding hole in this support piece and to prevent at least the nut from rotating on this piece.

Abstract: This electric conductor assembly includes an electric conductor in the form of a plate having a first surface and a second surface and comprising an aperture which extends through the conductor between these surfaces, and first and second spacing members which are supported on the first surface and the second surface at the periphery of the aperture. The assembly includes centering means for centering and immobilising the first and second spacing members radially relative to the aperture. Used in the production of electrical supply circuits, in particular for trains or motor vehicles.
