Abstract

The invention provides a strain clamp. The strain clamp comprises a clamp body and a drag hook, wherein the clamp body is provided with a wedge-shaped cavity and a drag hook through slot, the two side walls of the drag hook through slot are symmetrically provided with multiple pairs of connecting holes along the direction of the wedge shape, the two end parts of the drag hook are hook-shaped and can be inserted in the drag hook through slot and buckled in one pair of the multiple pairs of connecting holes, only one wedge-shaped sandwich body is arranged in each wedge-shaped cavity, the two sides of each wedge-shaped sandwich body are each provided with a C-shaped slot along the length direction of the wedge shape, the C-shaped slots and the wedge-shaped cavity wall of the corresponding wedge-shaped cavity can form a sandwich slot, the sectional area of each sandwich slot can be adjusted in a way of inserting the corresponding wedge-shaped sandwich body in or pulled the wedge-shaped sandwich body out of the corresponding wedge-shaped cavity. The strain clamp has the advantages of simple assembly, no relative sliding, uniform squeezing stress from two sides and high reliability.

Description

Technical field [0001] The invention relates to a cable clamp wire fitting, in particular to a strain wire clamp. Background technique [0002] In power overhead lines, the cluster insulated cables used for power transmission and distribution are generally two-core or four-core. In order to fix the cluster insulated cables on the poles, tension clamps are needed to withstand cable tension. The currently used strain clamps use the cross-shaped core on the body to divide the pair of bundled insulated cables from the middle into two parts. The pair of wedge-shaped sandwich cores on both sides clamp the cable, and the cable is tensioned in the wedge-shaped cavity of the body. The cooperation can make the cable more and more tight without damaging the cable. However, the existing strain clamps have technical problems such as difficulty in assembly, relative slippage on both sides of the cable, uneven compression force on both sides, and poor reliability. Summary of the invention [0...
