Description
Technical field
The utility model relates to a kind of built on stilts cable, relates in particular to a kind of built on stilts cable for telephone communication.
Background technology
Telephone communication cable is that single line is through twisting operation, then several groups of strands will be twisted into circular configuration with certain laying up pitch to line and carry out sheath again, this structure not only can be because workmen's pulling force is excessive, undue force causes the pitch that cable inner wire is right to change because stretching, thereby has influence on digital cable to every electric transmission performance in the time of construction wiring.The structure of telephone communication cable: the structure of common cable is that single line as the circular configuration of sheath, is mainly laid in residence interior trims netting twine or computer local area machine room to use PVC after stranding through strand.
Summary of the invention
The utility model provides a kind of built on stilts cable for telephone communication, this built on stilts cable for telephone communication has improved reliability and the life-span of product, also improved the transmission performance of cable, improve again pliability, prevent that frequent bending from causing polyethylene layer cracking, and cable is easily just separated, and can not destroy the cable core of cable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of built on stilts cable for telephone communication, comprise that steel wire and 2 are coated with the copper conductor of polyethylene layer, the first restrictive coating is coated on 2 described copper conductor outer surfaces, and the second restrictive coating is coated on steel wire outer surface; One bar shaped connecting portion is between the first restrictive coating and the second restrictive coating, and this bar shaped connecting portion arranged on left and right sides is equipped with v-depression; Described the first restrictive coating is made up of with the thermoplastic urethane layers that is positioned at outside the polyvinyl chloride layer that is positioned at inner side, and the first polyethylene rope, the second polyethylene rope are positioned at bar shaped connecting portion inside and lay respectively at v-depression both sides; In described polyethylene layer, edge is circumferentially distributed with several pores.
In technique scheme, further improve technical scheme as follows:
1. in such scheme, the number of slugs on described polyvinyl chloride layer surface is 8.
2. in such scheme, the surface that described polyvinyl chloride layer contacts with thermoplastic urethane layers has been uniformly distributed circumferentially several projections.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is for the built on stilts cable of telephone communication, ensureing on the basis of self-supporting cable tensile strength, by adopting the one V-type groove of the each increase in both sides in the middle of neck, the first polyethylene rope, the second polyethylene rope are positioned at bar shaped connecting portion inside and lay respectively at v-depression both sides, when cable is torn under tension, stress point all can concentrate on V-type groove part, and cable is easy to just separated, and can not destroy the cable core of cable; Secondly, described the first restrictive coating is made up of with the thermoplastic urethane layers that is positioned at outside the polyvinyl chloride layer that is positioned at inner side, the surface that described polyvinyl chloride layer contacts with thermoplastic urethane layers has been uniformly distributed circumferentially several projections, in external sheath layer, all have and contain several cavities, under pulling force effect, both realized high insulation, also realized corrosion-resistant, and restrictive coating does not separate or layering, reliability and the life-span of product are improved, also improved the transmission performance of cable, improved again pliability, prevented that frequent bending from causing polyethylene layer cracking.
