Abstract
The utility model discloses a kind of corrosion-resistant type telephone communication cable, and comprise the copper conductor that steel wire and 2 are coated with 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 first restrictive coating is made up of with the thermoplastic urethane layers being positioned at outside the polyvinyl chloride layer being 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.The utility model cable had both achieved high insulation, also achieve corrosion-resistant, and restrictive coating was not separated or layering, improve reliability and the life-span of product, and cable is easily just separated, and can not destroy the cable core of cable.
Description
Technical field
The utility model relates to a kind of self-supporting cable, particularly relates to a kind of corrosion-resistant type telephone communication cable.
Background technology
Telephone communication cable is that single line is through twisting operation, then several groups of strands will be twisted into circular configuration to line and carry out sheath again with certain laying up pitch, this structure not only can because workmen's pulling force is excessive, undue force causes the right pitch of cable inner line to change because stretching, thus has influence on digital cable to every electric transmission performance when constructing wiring.The structure of telephone communication cable: the structure of common cable is that single line uses PVC as the circular configuration of sheath after strand is to stranding, is mainly laid in residence interior trims netting twine or computer local area machine room.
Summary of the invention
The utility model provides a kind of corrosion-resistant type telephone communication cable, and this corrosion-resistant type telephone communication cable had both achieved high insulation, also achieved corrosion-resistant, and restrictive coating is not separated or layering, improve reliability and the life-span of product, and cable is easily just separated, and the cable core of cable can not be destroyed.
For achieving the above object, the technical solution adopted in the utility model is: a kind of corrosion-resistant type telephone communication cable, comprise the copper conductor that steel wire and 2 are coated with 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 first restrictive coating is made up of with the thermoplastic urethane layers being positioned at outside the polyvinyl chloride layer being 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 technique scheme, further improvement opportunity scheme is as follows:
1., in such scheme, the surface that described polyvinyl chloride layer contacts with thermoplastic urethane layers has been uniformly distributed circumferentially several projections.
2., in such scheme, the number of slugs on described polyvinyl chloride layer surface is 8.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model corrosion-resistant type telephone communication cable, on the basis ensureing self-supporting cable tensile strength, one v-depression is respectively increased by adopting the both sides in the middle of neck, first polyethylene rope, the second polyethylene rope are positioned at bar shaped connecting portion inside and lay respectively at v-depression both sides, v-depression width 0.2 ~ 0.5mm, the degree of depth 0.2 ~ 0.5mm, due to the existence of groove, cable is when under tension is torn, stress point all can concentrate on v-depression part, cable is easy to just separated, and can not destroy the cable core of cable; Secondly, described first restrictive coating is made up of with the thermoplastic urethane layers being positioned at outside the polyvinyl chloride layer being positioned at inner side, the surface that described polyvinyl chloride layer contacts with thermoplastic urethane layers has been uniformly distributed circumferentially several projections, under a stretching force, both high insulation had been achieved, also achieve corrosion-resistant, and restrictive coating is not separated or layering, improves reliability and the life-span of product.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model corrosion-resistant type telephone communication cable structure schematic diagram.
In above accompanying drawing: 1, steel wire; 2, copper conductor; 21, polyethylene layer; 3, the first restrictive coating; 31, polyvinyl chloride layer; 32, thermoplastic urethane layers; 4, the second restrictive coating; 5, bar shaped connecting portion; 6, v-depression; 7, projection; 81, the first polyethylene rope; 82, the second polyethylene rope.
