ABSTRACT:
A bracket provides a mechanical and electrical connection between a ground wire and a shielded cable. In one embodiment, a portion of the conductive sheath of the shielded cable is placed into an enlarged portion of a keyhole-shaped bore in a lug. The ground wire is placed into a reduced portion of the keyhole-shaped bore. A securing bolt threaded in an intersecting bore in the lug is then tightened to create a mechanical and electrical bond between the conductive sheath and the ground wire. In another embodiment, a pressure plate is placed into an oval shaped bore between the conductive sheath and the securing bolt. When the securing bolt is tightened, a mechanical and electrical connection between the conductive sheath and the bracket is accomplished through the pressure plate. In another embodiment, multiple first bores are fashioned through a lug to accept the ground wire in any of the bores without having to shape the ground wire into a hook-like connector. The securing bolt then engages the ground wire.
