ABSTRACT:
A method for manufacturing an electrical connector is disclosed in which the connector itself comprises an aluminum barrel member having a first and a second end, with the barrel member having a recess in its first end adapted to receive an electrical cable and a copper lead member extending axially out of its second end. The method comprises the steps of first forming a second recess in the second end of the barrel member, and forming one end of the copper lead member such that it includes a portion having a reduced cross-sectional area relative to the rest of the copper lead member. This end of the copper lead member is then inserted into the second recess in the barrel member, and electrical current is provided through the copper lead member and the barrel member while simultaneously applying force to bring the end of the copper lead member into engagement with the bottom of the second recess in the barrel member.
