Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a power cable protection tube to solve the problem that when the protection tube is protecting the cable, the unprotected cable position will be unevenly stressed, causing the protection tube to be disconnected from the cable. There will be bending phenomenon at the connection between the cables. If the cable is bent for a long time, it will cause the cable to break. For cables, if there is a little gap between the protective tube and the cable, when the cable is used in a humid environment, liquid or corrosive substances can easily enter the protective tube from the gap between the protective tube and the cable, thus directly contacting the cable sheath. Affect the protection effect of the cable, and there will be insects and ants biting the outer insulation of the cable, resulting in damage to the insulation wall, making the cable a potential safety hazard when using the cable, and reducing the use effect of the protective tube

Abstract

The invention discloses a power cable protection tube. The tube structurally comprises a connecting port, a telescopic device, a sleeve, a sealing device, a cable protection shell, a chuck and a connector. During use after improvement, a protection sleeve is used for clamping and protecting a cable, an extension pipe is adjusted, the cable which is not protected by a supporting table is supportedand protected, and an elastic rod and a protection ball are matched with the supporting table to perform buffer protection, so that the cable is stressed uniformly, the cable is protected, and the protection effect of the protection tube is improved; and the cable is arranged between two sealing washers, a magnet drives an extrusion plate to push the sealing washers forwards; the sealing washers are tightly attached to the outer wall of the cable, a screw and a spiral sleeve are mutually cooperated and screwed so that a clamping buckle is tightly buckled in a clamping groove in parallel, the cable can be fixed, clamped and protected through two protection shells, liquid or corrosive substances are prevented from permeating between the protection tube and the cable, and the protection effect of the protection tube on the cable is improved.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a power cable protection tube. Background technique [0002] With the development of science and technology, industry and other fields are also making rapid progress, and the proportion of cables is gradually increasing. Cables are usually rope-like cables with several or groups of wires twisted at least two in each group. The wires are insulated from each other and are often twisted around a center. The components of the cable from the inside to the outside include: conductor, insulation, inner sheath, filler and outer insulation. When protecting cables, areas that need improvement: [0003] 1. When the protective tube protects the cable, the position of the cable that is not protected will be bent due to uneven force, which will cause bending at the connection between the protective tube and the cable. The cable will be bent for a long time, which will cause The cable breaks, and ...
