Abstract

The invention relates to a shock absorption cable connector for a high-voltage cable, and belongs to the technical field of a cable material. By the shock absorption cable connector, the problem thatan existing cable connector is poor in shock absorption effect and is easy to get short-circuit is solved. The shock absorption cable connector comprises a cable connector body and a nut, wherein thenut is used for fixing the cable connector body, trapezoid threads are arranged at two ends of the cable body, the nut is provided with a thread matched with the trapezoid threads, the cable connectorbody comprises a cable connector body I and a cable connector body II, a filling cavity is arranged in the cable connector body I and / or the cable connector body II, and the cable connector body is sequentially provided with a sealing layer, a fireproof layer, a shielding layer, an insulation layer, a shock absorption layer, a waterproof layer and an outer protection sleeve from inside to outside. The shock absorption cable can be used for various cable connectors.

Description

technical field [0001] The invention relates to a shock-absorbing cable joint for high-voltage cables, which belongs to the technical field of cable materials. Background technique [0002] After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole, and these connection points are called cable joints. The cable joint is used to lock and fix the incoming and outgoing lines. Its main function is to make the line unobstructed, keep the cable sealed, and ensure the insulation level of the cable joint to make it run safely and reliably. In the process of construction and use, cables are inevitably impacted by external forces. Strong impacts will cause the sealing performance of cable joints to decline. Cause fire and electric shock accident etc., cause immeasurable loss. Contents of the invention [0003] The object of the present invention is to provide a shock-absorbing cable joint for high-voltage cables, which can...
