Abstract: A clamp for electrical cable, especially flat cable, wherein opposed jaws allow passage of the cable therethrough with fasteners providing inward biasing of the jaws toward mutual contact. Two recessed groove sections in each jaw provide a seat for the cable, including a more deeply recessed toothed section which grips the cable sheath, if any, and a less deeply recessed section which seats unsheathed cable. The jaws may be supported, vertically or horizontally, by stand-offs relative to a support structure. A conductive path is provided from the jaws, through the standoffs, to a support structure (electrical ground), for the purpose of grounding a wire mesh cable ground, frequently surrounding flat cable. The clamp is used proximate a cable connector so that the clamp and connector provide a complete mechanical and electrical cable termination system.
