  • Patent number: 4487990
    Abstract: A dual polarity terminal for a water-cooled, kickless welding cable having a plurality of electrical conductors, each half terminal having one half of the electrical conductors fixedly crimped thereto in a single manufacturing step. A series of overlapping bore openings in the end face of each half terminal form a socket which is mechanically welded to the sidewall of the half terminal in a press. A particularly shaped lie leaves an axially-extending depression near the rear of the half terminal which acts as a water passageway. An insulating strip electrically isolates the two halves of the dual polarity terminal.
