  • Cable clamp
    Patent number: 5392496
    Abstract: A cable clamping mechanism (10) having first and second jaws (24, 26) for clamping a cable (12). First and second backstops (20, 22) are fixed to a top plate (18) on opposite sides of the jaws. A first wedge (52) is slidably mounted between the jaws and the second backstop.
