A communication cable protection tube

Abstract

The invention relates to a communication cable protection pipe, which comprises two pipe bodies, a sealing and clamping device, two sealing sleeves and a connecting pipe, wherein the sealing and clamping device is arranged between the two pipe bodies, the two sealing sleeves are arranged at the front end and the rear end of the sealing and clamping device, and the connecting pipe is arranged at the right end of the sealing and clamping device. The communication cable protection pipe can solve the problems that the internal part of the existing protection pipe is mostly of a cavity structure, cables are easy to mix together to result in harmonic interference and the like, the structural strength of the protection pipe with the cavity structure is relatively low, the protection pipe is easyto be damaged when being extruded after the protection pipe is buried in the ground, thus soil enters the inner wall of the protection pipe, the internal cables need to be cut off while the damaged protection pipe is cut off when the protection pipe is damaged, the cables are connected again after the new protection pipe is connected with the cut-off interface, the gap structure between new protection pipe and the original protection pipe interface is unstable, the situation of breakage is easy to occur and the like.

Description

Technical field [0001] The present invention relates to the field of communication cable protection, in particular to a communication cable protection tube. Background technique [0002] Communication cable, a general term for various wires that transmit electrical or optical signals. When the communication cable is buried in the ground, the communication cable is usually inserted into the protective tube of the integrated structure and buried in the ground together. The setting of the protective tube The direct contact between the communication cable and the soil is avoided, and the integrated structure improves the tightness of the protection tube. However, the integrated protection tube still has some problems: [0003] 1. Most of the existing protection tubes have a cavity structure inside, and cables are easily mixed together, resulting in harmonic interference, etc. The structural strength of the protection tube in the cavity structure is low, making it squeezed after being b...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the existing protective tubes have a cavity structure inside, and the cables are easily mixed together, resulting in harmonic interference and other situations. The structural strength of the protective tube in the cavity structure is low, so that it will be squeezed after being buried in the ground. It is prone to damage when pressed, which will cause soil to enter the inner wall of the protection tube;

[0004] 2. When the protective tube is damaged, it is necessary to cut the internal cable while cutting the damaged protective tube, and then reconnect the cable after the new protective tube is connected to the cut-off interface. The process is cumbersome and complicated, and the new protective tube The structure of the gap between the pipe and the original protective pipe interface is unstable and prone to rupture
