  • Patent number: 5033982
    Abstract: A three component connector for use with high voltages. The connector is attached to a plastic cable enclosing multiple strand wire threaded through an inner shield of the connector. The plastic cable is stripped at its end to expose the multiple wires which are crimped to a pair of crimping arms integral with a barrel connector. A pair of strain relief arms, also integral with the barrel connector grip the plastic cable. The barrel connector is pulled into the inner shield. The inner shield is snapped to the outer shield by pushing it through an opening at a first end. At a second end of the outer shield an opening receives a male connector.
