Abstract: In an assembly comprising an electrically conducting bar, lower and upper electrically insulating films covering opposed faces of the conducting bar, and an electrically insulating member bonded to the upper insulating film, the insulating member protruding on the exposed face of the insulating film so as to prevent propagation of electric arcs by tracking on said exposed face, the insulating member is bonded to the insulating film with a heat-sealable coating.

Abstract: This system in which support piece is provided with a threaded pin designed to be engaged in a hole of conductor and to cooperate with a nut for screwing the conductor onto this piece, is characterized in that an annular spacer of electrically conductive material is joined to conductor on the side of this conductor that is facing the support piece, in that a ring is positioned on the opposite side of this conductor and includes floating means for coupling onto spacer designed to extend through hole of the conductor and in that nut is joined to the ring by coupling means allowing the rotation of nut relative to the ring and a determined course of axial movement for this nut relative to this ring, between a position of assembling distant from the ring and a position for screwing in which the nut is supported against the ring in order to facilitate the positioning, and then the screwing of conductor against support 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.

Abstract: The invention relates to a contact disc (1) for a conducting plate (2) of busbars, comprising a contact surface (3) projecting upwards with respect to the surface of the conducting plate where the contact surface (3) is integral with the conducting plate (2) and where the segment-shaped slots (4a, 4b 14) are arranged all around, to make possible a deformation of the plate without a significant reduction of the surface of the contact disc provided for receiving an electronic component.
