摘要

A shield bond strain connector for a cable which has strength members therein, such as a fiber optic telecommunications cable having an outlet jacket surrounding the strength members and optical fibers, the connector having: (i) an inner clamping element (56) positioned against an inner surface of the cable jacket, with a first mounting bolt (60) attached to the inner clamping element, and a prong (66) formed along an end of the inner clamping element; (ii) an outer clamping element (54) positioned against an outer surface of the cable jacket, having a hole (62) therein receiving the first mounting bolt, and being forcibly urged against the cable jacket toward the inner clamping element; (iii) a clamping plate (90) having a second mounting bolt (84) thereon; and (iv) a shield bond extension element (70) having first, second and third holes (76, 78, 80) therein, the first hole receiving the first mounting bolt, the second hole receiving the prong, affixing the extension element to the inner and outer clamping elements, while the third hole receives the second mounting bolt, securely fastening the strength members between the clamping plate and the extension element. The first mounting bolt extends the same direction as the second mounting bolt. The extension element has a narrowed end portion (82) which is interposed between the inner and outer clamping elements, with the first hole being formed in the narrowed end portion. A flange formed on the clamping plate provides a positive stop and a friction fit with the top edge of the shield bond extension element. Each of these elements is preferably formed of a metallic material, such as tin-plated brass. The connector extends the shield bond and provides strain relief to the strength members located within the cable jacket.
