  • Cable grounding system
    Patent number: 4140870
    Abstract: An improved fastener assembly system for grounding multiconductor, shielded cables. The assembly includes a saddle-shaped stud device and a preassembled nut and clamping washer. The clamping washer including a conical spring section and downwardly extending penetrating teeth to pierce the outer insulative sheath of the cable bringing the teeth into conductive contact with the metallic shield. The penetration of the teeth through the outer layer of elastomeric material eliminates the cold flow relaxation problems which could contribute to an ineffective grounding system.
