Fastening part used for wire clamps

Abstract

The invention discloses a fastening part used for wire clamps. The fastening part used for the wire clamps comprises a bolt and a nut, wherein the bolt head comprises a head part, a threaded rod partand an abut-against strip part which is made of a shape memory alloy material, one end of the threaded rod part is connected to the head part, the other end of the threaded rod part is connected to one end of the abut-against strip part; the threaded rod part is used for connecting guide parts of multiple wire clamps; the nut movably sleeves the threaded rod part, and the nut and the head part define clamping and fixing for the guide plates of the wire clamps; the abut-against strip part is restored to an inverse phase transformation ending state with the head part for clamping and fixing theguide plates from a phase transformation ending state while a wire clamp heating temperature exceeds an inverse phase transformation ending temperature of the abut-against strip part; and stable connection, in long-term use, of the guide plates is guaranteed, so that a condition that the wire clamps heat to affect stable operation of a power transmission line is reduced.

Description

technical field [0001] The present application relates to the technical field of power transmission and transformation equipment, in particular to a fastener used for a wire clamp. Background technique [0002] The wire clamp on the transmission line is an important electric fitting. As a part of the wire clamp, the diversion plate not only needs to withstand the pressure of the wire, but also needs to have good electrical properties. The connection between the existing multiple wire clamps is through bolts. The component connects and fixes the sheet-like drainage plates of the cable clips. This is a relatively conventional fixing method. However, power transmission and transformation equipment has its own particularity. The transmission line is located outdoors. Due to years of wind and vibration, it is easy to cause the drainage plates to connect. The slack will lead to poor contact of the drainage plate, which will cause the clamp to heat up, and ultimately affect the sta...
