Communication wire and cable insulation sheath

Abstract

The invention relates to a communication wire and cable insulation sheath. The sheath comprises a mounting cover, sleeves, a fixing rod and a fixing unit, the two sleeves are mounted in the inner sideof the mounting cover in a clamping manner; the left end of the sleeve in the right side of the mounting cover is connected with the right end of the sleeve in the left side of the mounting cover ina clamping manner; fixing holes are formed in the front side and the rear side of the mounting cover, a fixing rod is installed in the fixing hole located in the front end of the mounting cover in a sliding fit mode, and a fixing unit is installed in the fixing hole located in the rear end of the mounting cover in a sliding fit mode. The insulation sheath of the invention can be used to solve theproblems that in the existing process that an insulation sheath wound on a cylinder is used for sleeving and laying an electric wire and a cable, sleeving is difficult and sometimes can be conducted only after the insulating sheath is cut off, and the efficiency of sleeving the insulating sheath on the electric wire and the cable is low; and that wires and cables are not fixed, the wires and cables are easy to displace and bend when buried in soil, and bent parts on the surfaces of the wires and cables are damaged.

Description

technical field [0001] The invention relates to the field of insulating sheaths, in particular to an insulating sheath for communication wires and cables. Background technique [0002] In the laying process of communication wires and cables, when laying buried wires, because the wires and cables need to be buried underground, a layer of insulating protective tubes will be placed on the outside of the wires and cables to protect the wires. , Cables are protected to prevent soil, water, etc. from directly contacting the surface of wires and cables; [0003] The insulating sheath wound on the cylinder is generally used in the existing market. However, the following problems usually exist in the process of sheathing and laying wires and cables with the insulating sheath wound on the cylinder: [0004] 1. Since the length of the insulating sheath wound on the cylinder is long, and the insulating sheath wound on the cylinder is bent after being torn off due to being wound, so whe...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the length of the insulating sheath wound on the cylinder is long, and the insulating sheath wound on the cylinder is bent after being torn off due to being wound, so when the insulating sheath is wound on the wire and cable It is difficult to set the upper sleeve, so that the laying workers will cut off the insulating sheath wound on the cylinder piece by piece, and then set it on the outside of the wire and cable in turn, but the insulating sheath is cut off at this time The protective effect at the place will be reduced, and the step of cutting the insulating sheath will be increased, thereby reducing the efficiency of placing the insulating sheath on the wire and cable;

[0005] 2. When the insulating sheath is placed in the wire and cable grooves on the ground after the sleeve is installed, since the insulating sheath is not fixed in the wire and cable grooves on the ground, it is easy to bury the soil in the groove Displace the wires and cables, make the wires and cables bend, and there is internal stress at the bends. Since the wires and cables are buried underground, they will basically not be dug out, and the bends will always be in a bent state, so it is easy to cause wires and cables to be damaged. , The bend of the cable surface is damaged
