1. An electrical cable assembly comprising:a plurality of stranded electrically conductive fibers of wire extending from a first end to a second end;
an electrical insulator surrounding the plurality of strands of wire, such that each of the first and second ends extends out from the electrical insulator, wherein the fibers of wire of at least the first end are fused to each other so as to define a solidified shape having at least one keyed surface;
a first electrically conductive contact member comprising at least one contact surface in surface contact with the at least one keyed surface of the solidified shape;
a first electrically conductive arm in electrical contact with the first electrically conductive contact member; and
a second electrically conductive arm that cooperates with the first electrically conductive arm to define a receptacle.
