  • Patent number: 5083929
    Abstract: A bulkhead grounding connector for a multi-conductor shielded cable is fabricated from a base and an identical cover. A resilient plastic tube is positioned within the cable between its metal foil and wire braid layers and provides a spring-like surface to push the wire braid against rigid conductive fingers located on the inner surface of the base and cover. Scraping motion of the fingers against the wire braid during assembly ensures removal of resistive oxides from the braid. Sharp dimples positioned longitudinally on the inner surface of the base and cover provide additional ground connection around the circumference of the cable.
