  • Patent number: 4257658
    Abstract: A cable shield connector assembly for making electrical connections to the shield of a multi-conductor communications-type cable includes a split cylindrical sleeve having circumferentially spaced contact ridges for insertion about the conductors and within the shield and further includes clamp halves positioned about the sleeve with a portion of the shield and the external insulation sheath of the cable therebetween. The clamp halves are drawn together by screws to urge the shield into electrical contact with the ridges of the sleeve. The sleeve includes a tab projecting through a slit in the shield and sheath to receive a screw for connection of a ground conductor thereto. The tab preferably extends between a portion of the clamp and receives one of the clamping screws therethrough to thereby locate and fix the clamp halves around the sleeve.
