APPARATUS FOR ELECTRICALLY TESTING MOLDED CORD-SETS DURING THE MOLDING OPERATION

摘要

In accordance with the present invention, there is provided an improved arrangement for and method of electrically testing a cord-set during the molding of the male plug and female receptacle to the opposite ends of the insulated electric cord. In order to accomplish this, the mold for forming the molded plug and receptacle is provided with suitable contacts which upon the closing of the mold automatically establish electrical connections between the terminals of the cord-set and circuits in testing apparatus. These tests consist of checking for continuity in each conductor and for shorts between conductors or terminals and a skin ground test for the purpose of detecting stray strands of wire or any current carrying object that would carry current to the outside surface of the molded plug or receptacle. For the latter test, the metal of the mold itself, which closely embraces the entire outer surfaces of the plug and receptacle, serves as the ground as it is in contact with any conducting particle which extends to the outer surface.
