ABSTRACT:
The present invention uses molded components to receive the ends of electrical zip cord. Elongated contact pins which are molded into the components are inserted axially into the ends of the stranded conductors at the end of the zip cord making positive electrical contact to the conductors. Ridged portions within the molded components receive, grip, and retain the insulator on the outer portion of the zip cord, thereby separating the functions of electrical gripping and mechanical contact in the present invention.
