ABSTRACT:
An electrical connector and a method of making the same in which the electrical connections of contacts to the bared ends of the stranded conductros of a cord are positioned within two layers of insulating material. An inner body of insulating material has spaced arms joined to a base with each arm surrounding a corresponding one of the connections. The inner body is injection molded in a mold cavity with serrated or other type irregularly shaped inner surfaces which provide a turbulent flow of fluid insulating material that tends to force any loose strand at the bared ends of the conductors away from the inner surfaces. An outer body of insulating material is injection molded around the inner body and between the arms of the inner body.
