Three-core cable and cable head positioning device and using method thereof

Abstract

The invention provides a three-core cable and a cable head positioning device and a using method thereof. The three-core cable comprises a three-core cable body and a wire end positioning tool, the wire end positioning tool comprises an outer sleeve ring and an inner lock ring, the inner wall of the outer sleeve ring is fixedly connected with an elastic stretching piece, the end, away from the outer sleeve ring, of the elastic stretching piece is fixedly connected with the outer wall of the inner lock ring, and the inner wall of the outer sleeve ring is fixedly connected with an anisotropic elastic stretching piece. According to the three-core cable and the cable head positioning device thereof, the threaded positioning column is aligned with the interior of the threaded groove, the wirewinding iron disc is rotated by a tool, the wire winding iron disc drives the threaded positioning column to rotate, the threaded positioning column rotates and is locked in the threaded groove, the wire winding iron disc winds the soft steel wire rope, and the soft steel wire rope pulls the fitting tool, so that the fitting tool shrinks and binds the cable, the cable head is fixed, the operationis simple, the structure is compact, the wire head positioning device is convenient to disassemble and assemble, the cable head is convenient to butt and maintain, and the practicability is high.

Description

[0001] This application is a divisional application with an application date of July 26, 2018 and an application number of CN201810831144.X, whose invention name is a three-core cable and its wire end positioning device. technical field [0002] The invention relates to the technical field of cables, in particular to a three-core cable and its wire end positioning device and usage method. Background technique [0003] Existing three-core cables usually include a cable inner core covered with an insulating layer, and a cable jacket outside the insulating layer. The wire ends of the three-core cable generally need positioning equipment to be fixed. [0004] However, the traditional three-core cable and its wire end positioning device have the following disadvantages: [0005] 1) Most of the traditional thread positioning devices are bonded with glue, which is easy to fall off after long-term use, cannot be effectively restrained, and is not easy to maintain; [0006] 2) When ...

AI Technical Summary

Problems solved by technology

[0005] 1) Most of the traditional thread positioning devices are bonded with glue, which is easy to fall off after long-term use, cannot be effectively restrained, and is not easy to maintain;

[0006] 2) When the three-core cable is suspended in the air, the wind resistance effect is poor, which makes the three-core cable easy to shake;

[0007] 3) The safety of the three-core cable is low
