Abstract: A method of connecting an electrical wire cable having a plurality of uninsulated wire strands to an electrical terminal is presented. The method includes the steps of crimping an electrical wire cable within a crimping feature of an electrical terminal having wire strands protruding from the crimping feature and fusing the wire strands of protruding portion, or “wire brush” so that the wire strands are in intimate contact, thereby eliminating voids between individual wire strands of the wire brush. The wires may be fused by laser welding, soldering, or brazing. The method may be especially beneficial for wire strands having an insulative oxide layer, such as aluminum. The bonding reduces the resistance between the wire strands due to insulating oxide layers on the surface of the wire strands and inhibiting of corrosion by eliminating inter-strand gaps where electrolytes in solution may enter and cause galvanic corrosion.

Abstract: An electroconductive material having a base member formed of copper-based material and a coating layer overlaying the base member. The coating layer may be formed of tin-based, nickel-based, copper-based, silver-based, or gold-based materials. An undulate surface of the coating layer defines a plurality of crests and troughs. Each trough in the plurality of troughs has a depth of at least one half micron (0.5 μm) relative to each adjacent crest in the plurality of crests. A distance between adjacent crests in the plurality of crests is between twenty microns (20 μm) and one hundred microns (100 μm). This electroconductive material may form the contact surface of an electrical terminal in an electrical connection component and is effective to improve fretting corrosion resistance. A method of manufacturing such a electroconductive material is also presented.

Abstract: An electrically-conducting contact element includes a section of the contact element defining an aperture. The section is configured to receive a wire cable within the aperture for attachment thereto. The section includes an internal surface with at least one groove having sharp edges formed therein. A wire assembly that includes the electrically-conducting contact and a method to construct the electrically-conducting contact are also presented. The method includes a step of providing the contact element and forming a sharp edge on the internal surface of the contact element. A further step in the method includes altering material on the internal surface of the contact element by a forming means. The forming means may be one of milling, rifling, machining, cutting, indenting, or stamping. A wire assembly and a vehicular electrical wiring harness that respectively include the contact element are also presented.
