Conical locking type strain clamp convenient for maintenance

Abstract

The invention discloses a conical locking type strain clamp convenient for maintenance, and aims to provide a conical locking type strain clamp which is not only convenient to assemble, disassemble and maintain, but also stable in strain clamp structure and capable of effectively solving a problem that the service life of the strain clamp is influenced and the power supply reliability is reduced due to looseness between an upper drainage member and a jumper drainage member. The conical locking type strain clamp comprises a clamp body and a drainage body, wherein the clamp body is connected with a wire. The drainage body comprises an upper drainage rod, a jumper drainage rod and a locking connecting nut, and is characterized in that the upper part of the upper drainage rod is connected withthe clamp body, and the lower end face of the upper drainage rod is provided with a conical insertion hole; the upper part of the jumper drainage rod is provided with a conical insertion rod matchedwith the conical insertion hole, and the conical insertion rod is inserted in the conical insertion hole; and the locking connecting nut is arranged on the jumper drainage rod in a sleeved manner. Thelower end of the upper drainage rod extends into the locking connecting nut, and the locking connecting nut is connected with the upper drainage rod through a thread.

Description

technical field [0001] The invention relates to a tension wire clamp, in particular to a tapered locking type tension wire clamp which is convenient for maintenance. Background technique [0002] The current strain clamp includes a clamp body and a drainage body. The clamp body is connected to the wire, and the drainage body usually includes an upper drain connected to the clamp body and a jumper drain connected to the jumper. The upper drain and the jumper drain are connected by nuts or bolts. The upper drainage part of the drainage body and the jumper drainage part are connected by bolts. Although this connection structure is convenient for maintenance and replacement, it is easy to connect the bolted upper drainage part and the jumper drainage part during the long-term use of the power line. Looseness occurs, and once there is looseness between the upper drainage piece and the jumper drainage piece, the resistance between the upper drainage piece and the jumper drainage ...

AI Technical Summary

Problems solved by technology

The upper drainage part of the drainage body and the jumper drainage part are connected by bolts. Although this connection structure is convenient for maintenance and replacement, it is easy to connect the bolted upper drainage part and the jumper drainage part during the long-term use of the power line. Looseness occurs, and once there is looseness between the upper drainage piece and the jumper drainage piece, the resistance between the upper drainage piece and the jumper drainage piece will increase, causing the drainage body to heat up; after the drainage body heats up, it will It will further increase the resistance between the drainage body and the clamp body, resulting in a vicious circle, seriously affecting the service life of the tension clamp, and even breaking the tension clamp, reducing the reliability of power supply
