Abstract

The invention discloses an insulator for preventing a cable from loosening, and the insulator comprises an insulator, a fixed circular block, a locking nut, and a cable locking auxiliary mechanism. When the insulator and the cable are connected and installed, a card at the end part of the cable is clamped and fixed through the fixed circular block and the locking nut; then the locking nut is locked through clamping and fixing of a first movable positioning column and a first fixed circular groove, then the cable is placed on an arc-shaped elastic plate arranged in a bunching pipe, and the cable is locked and fixed through the arc-shaped elastic plate by rotating a lantern ring; therefore, influence of strong wind on the connection and fixation of the cable and the insulator is avoided, thefirmness and stability of connection between the insulator and the cable are ensured, the phenomenon of loose connection is prevented, and the normal use and normal work of a line are ensured.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to an insulator for preventing cable loosening. Background technique [0002] An insulator is a device installed between conductors of different potentials or between conductors and ground potential components. It can withstand voltage and mechanical stress. It is a special insulation control that can play an important role in overhead transmission lines. Early During the years, insulators were mostly used on utility poles, and gradually developed in the high-voltage wire connection tower. Many disc-shaped insulators are hung on one end of the tower. It is to increase the creepage distance. It is usually made of glass or ceramics, and it is called an insulator; the insulator is not It should fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not have a significant effect and will damage ...
