Abstract
Abstract Contact-forming coupling means for a current conductor cable for electrode welding having two clamp members of electrically insulating material for fastening a conductor portion to a fastening plate by abutting opposite sides of the latter by means of a nut and a plate spring clamped against one clamp member on the rear side of the fastening plate. The other clamp member is located on the front side of the fastening plate in a rubber sleeve for physical protection of the coupling means and for providing with the fastening plate a seal against fluid. An endways and outwardly projecting collar portion of the sleeve provides extra physical protection for the coupling means and an additional seal against fluid for an inserted element in the form of either a cooperating coupling means connected to the current conductor cable or a closing plug.
