Abstract
Abstract A connector for coupling an electrical conductor to a terminal comprising a wire barrel arranged to be mechanically deformed about the portion of an electrical conductor from which the insulation has been removed to provide an electrical and mechanical connection therewith and a terminal-engaging means coupled to said wire barrel. A plurality of apertures extend through the wire barrel to permit the extrusion of adjacent portions of the metal of the conductor into such apertures to improve the mechanical and electrical coupling therewith. Further, the apertures will permit the breakdown of surface oxides to insure a good electrical connection with the conductor. An insulating jacket may be placed atop the wire barrel and deformed portions of the insulating jacket will also penetrate the apertures to securely, mechanically lock the jacket to the wire barrel.
