Embodiment Construction

[0018] Such as figure 1 and 2 As shown, the self-supporting horizontal twisted pair communication cable includes several cables 1 and sheaths 2 arranged around them. The cables 1 are twisted together. Each cable 1 includes a cable core 11 and a cable sheath 12 covering the periphery of the cable core 11. The cable core 11 is an annealed solid copper conductor. The number of cables 1 in this embodiment is four.

[0019] The cross section of the sheath 2 is flat, and V-shaped grooves 21 are symmetrically arranged on both outer walls of the sheath 2 . The groove body 21 divides the sheath 2 into an upper half 22 and a lower half 23, the upper half 22 is provided with an axially extending load-bearing line 3, the lower half 23 is provided with an axially extending cable 1, and the lower half 23 is provided with an axially extending cable 1. The portion 23 is also provided with a tear cord 4 located on the side of the cable 1 and extending axially.

Abstract

The invention relates to a self-bearing horizontal twisted pair communication cable, belonging to the technical field of communication. The invention solves the problems of the prior art that the design is unreasonable, the operation and the use are inconvenient and the like. The self-bearing horizontal twisted pair communication cable comprises a plurality of cables and a sheath arranged on the periphery of the cables. The cross section of the sheath is flat. V-shaped grooves are symmetrically arranged on the two outer side walls of the sheath. The grooves divide the sheath into an upper half part and a lower half part. Axially extended bearing lines are arranged at the upper half part and axially extended cables are arranged at the lower half part. Moreover, an axially extended rip cord is arranged at the side part of the cables at the lower half part. The self-bearing horizontal twisted pair communication cable has the advantages that: 1. the weather resistance and the aging resistance are strong and the service life is long; 2. since the sheath is flat and the V-shaped grooves are arranged on the two sides, the positioning can be realized very conveniently and thereby rapid operation and installation are realized; and 3. since the rip cord is arranged, the sheath can be conveniently ripped, the structural destruction during installation of the cables is avoided, and the installation, the succession and the maintenance are very convenient.

Description

technical field [0001] The invention belongs to the technical field of the communication field and relates to a communication cable, in particular to a self-supporting horizontal twisted pair communication cable. Background technique [0002] The communication cable consists of a plurality of mutually insulated wires or conductors to form a cable core, and a communication line with a sealed sheath on the outside. Communication cables are widely used in the field of communication technology, and their performance has an important impact on communication effects. [0003] In order to improve the work performance, people have carried out long-term exploration and proposed various schemes. For example, the Chinese patent literature discloses a self-supporting twisted pair communication cable [application number: CN200620116836.9], which is composed of one or more than five pairs of core wires with insulating sheaths and a low-carbon steel wire Composition, the conductor core w...
