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.

In order to improve service behaviour, people have carried out long-term exploration, have proposed various schemes.For example, Chinese patent literature discloses a kind of self-bearing type pair twist telecommunication cable [application number: CN200620116836.9], it has the insulating covering conductor core wire by a pair of or five pairs of as many as and a mild steel wire muscle line is formed, described conductor core wire and described steel wire muscle line all are provided with oversheath, and both oversheaths connect as one, its cross section is " 8 " font, and described oversheath is made with the black polyethylene material, and described every pair of conductor core wire is according to being provided with less than the long pitch pair twist of 4.5cm.The somebody has invented a kind of optical cable [application number: 200910151703.3] of tearing rope that has, and it comprises at least: an insulating barrier, be positioned at light or electric conductor within the insulating barrier, be coated on the protective layer outside the insulating barrier and be positioned at restrictive coating outside the protective layer; It is characterized in that between insulating barrier and light or electric conductor, being placed with continuously and tear rope; Or be placed with continuously between insulating barrier and the protective layer and tear rope; Or all be placed with continuously between insulating barrier and light or the electric conductor and between insulating barrier and the protective layer and tear rope.Owing to tearing that rope has enough intensity and be to place continuously,, do not need professional instrument, and can not hinder hand so when construction, only need haul and tear rope and can open stripped cable.
Such scheme has improved performance to a certain extent, but it is not high still to exist structural strength, is difficult to the location, can't realize technical problems such as self-supporting.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of reasonable in design, simple in structure, weatherability and ageing resistance are strong, are easy to the location, the self-bearing horizontal pair twist telecommunication cable that mechanical strength is high.
For achieving the above object, the present invention has adopted following technical proposal: this self-bearing horizontal pair twist telecommunication cable, comprise some cables and be located at its peripheral sheath, it is characterized in that, described sheath cross section is flat, two lateral walls at sheath are provided with V-shaped cell body symmetrically, described cell body is divided into the first half and Lower Half with sheath, be provided with axially extended load-bearing line at the first half, be provided with axially extended described cable in Lower Half, also be provided with in Lower Half and be positioned at cable sidepiece and the axially extended rope of tearing.
Because sheath is flat and is provided with the cell body of V-type in both sides, therefore can realize the location easily, thereby realize quick operation and installation.Owing to be provided with the load-bearing line, therefore can realize self-supporting.Owing to be provided with and tear rope, can easily sheath be peeled off, avoid cable structural destruction in installation process, to occur.
In above-mentioned self-bearing horizontal pair twist telecommunication cable, described load-bearing line forms by some zinc-coated wires are stranded.Zinc-coated wire is the structural strength height not only, and has good anti-corrosion.
In above-mentioned self-bearing horizontal pair twist telecommunication cable, described sheath is made by smokeless modified PVC.Adopt smokeless modified PVC can effectively improve pollution, be convenient to reclaim and regeneration is used environment.
In above-mentioned self-bearing horizontal pair twist telecommunication cable, described cable twists together, and every cable comprises cable core and the cable cover that is coated on the cable core periphery respectively.
In above-mentioned self-bearing horizontal pair twist telecommunication cable, the first half of described sheath and the aspect ratio of Lower Half are 1: 2, and the sheath edge has fillet.
In above-mentioned self-bearing horizontal pair twist telecommunication cable, the height of described sheath is 7.3mm-8.0mm, and width is 4.4mm-5.0mm, and the cell body degree of depth is 1.9mm-2.3mm, and the width of rebate of cell body is 0.3mm-1.5mm.
In above-mentioned self-bearing horizontal pair twist telecommunication cable, described cable core is annealing solid copper conductor.
Compared with prior art, the advantage of this self-bearing horizontal pair twist telecommunication cable is: 1, reasonable in design, simple in structure, weatherability and ageing resistance are strong, long service life.2, because sheath is flat and is provided with the cell body of V-type in both sides, therefore can realize the location easily, thereby realize quick operation and installation.3, tear rope owing to being provided with, can easily sheath be peeled off, avoid cable structural destruction in installation process, to occur, install, continue, maintain all very convenient.
