WIRE HARNESS ASSEMBLY

摘要

A wiring harness assembly is presented. The wiring harness assembly is formed by a method that 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.

主权项

1. A wiring harness assembly, comprising:
an electrical wire cable including an end having a plurality of uninsulated wire strands; an electrical terminal attached to the electrical wire cable by the method of: crimping an uninsulated end of the electrical wire cable within a crimping feature of the electrical terminal, wherein a portion of the plurality of uninsulated wire strands protrudes from the crimping feature; welding the portion of the plurality of uninsulated wire strands protruding from the crimping feature so that at least a majority of the wire strands are bonded together, thereby eliminating voids between individual wire strands of the portion of the plurality of uninsulated wire strands protruding from the crimping feature; and shaping an end portion of the portion of the plurality of uninsulated wire strands protruding from the crimping feature to provide a smooth end of the portion of the plurality of uninsulated wire strands protruding from the crimping feature.
