ABSTRACT:
A method of making a plastic terminal connector having a metal terminal set embedded therein in which the conductive contact members of the terminal set are electrically isolated from each other prior to the injection molding process. There is included a three-plated mold base which is formed from a lower movable mold plate, an intermediate mold plate, and an upper stationary mold plate. The upper mold plate includes a plurality of punches which extend through the spring-biased intermediate mold plate so as to cut connecting ties of the metal terminal set so as to form a plurality of individual electrically isolated conductive contact members when the mold is closed. The cutting operation is performed prior to the injection molding process as an integral part of loading the metal terminal set into the lower mold plate and securing the terminal set within the mold between the lower and intermediate mold plates when the mold is closed.
