STRINGING CLAMP

PROBLEM TO BE SOLVED: To provide a stringing clamp which does not damage an aluminum wire of a steel core aluminum twist wire during passing through a sheave, can be easily installed, and has a simple and inexpensive structure.SOLUTION: A stringing clamp 1 is composed of a clamp body 2, an elastic cover 3, and a fixing ring 4. The clamp body 2 is provided with: a strand insertion hole 2b in which an end portion of an electric wire E installed with the elastic cover 3 is inserted; and a steel core wire insertion hole 2c in which a steel core wire E1 extending from the electric wire E is inserted. The elastic cover 3 is configured by synthetic resinous pipe material for coating the electric wire E, and an end portion is inserted in the strand insertion hole 2b with the electric wire E. The fixing ring 4 is compressed and fixed at a position adjacent to the elastic cover 3 on the electric wire E. The clamp body 2 fixes the steel core wire E1 in a compression area P1 in which the steel core wire E1 is inserted and compressed, and on the other hand, permits the movement of an aluminum wire on the outside of a curving portion during passing through a sheave, by a semi-compression area P2 in which the elastic cover 3 is inserted and compressed except for a mouth part and the electric wire E is loosely fixed.
