Description

Stretch-proofing cable

Technical Field

The utility model relates to the technical field of cables, concretely relates to stretch-proofing cable.

Background

The cable generally comprises a primary outer protective layer of conductive metal wires, the outer protective layer is mostly a belting layer, an insulating layer, a shielding layer and an armor sheath layer, the cable is widely applied to various fields such as factories, office buildings, recreational places and the like, so the using amount of the cable is particularly huge, the cable is particularly important, the requirement on quality is very high, but the requirement on the quality and the use of the cable is not the same in various fields, along with the development of the society, the cable also needs to be continuously improved to be better put into use, the general cable has a simple structure and a single function, the tensile resistance performance is greatly insufficient, the tension is overlarge, the cable is easily deformed, the rubber filling layer inside the cable is deformed, and the whole cable is elongated and thinned.

Therefore, a need exists for a stretch resistant cable.

SUMMERY OF THE UTILITY MODEL

For this, the utility model provides an anti-stretching cable, through the covering of polyurethane lag inlayer wall around the band, be equipped with the baffle around the band centre, the baffle front end is equipped with logical hole site with the rear end, through-hole position inner wall installation stay cord, the through-hole position is through the fixed stay cord of mounting, the baffle excircle sets up to the circular arc arch, be equipped with the inner groovy between two sets of circular arc arcys, place the wire in the middle of the inner groovy to solve the pulling force too big, lead to the cable to warp easily, make the inside rubber filling layer of cable warp, lead to the problem that whole cable elongated.

In order to achieve the above object, the present invention provides the following technical solutions: stretch-proofing cable, including polyurethane protective sheath layer, polyurethane protective sheath inlayer wall covers around the band, be equipped with the baffle around the middle of the band, the baffle front end is equipped with logical hole site with the rear end, logical hole site inner wall installation stay cord, lead to the fixed stay cord of hole site, the baffle excircle sets up to the circular arc arch, and is two sets of be equipped with the inner groovy between the circular arc arch, place the wire in the middle of the inner groovy.

Preferably, the fixing piece is a screw, an internal thread through hole is formed in the through hole position for installing the fixing piece, and the bottom of the fixing piece is connected with the pull rope.

Preferably, a rubber filling layer is arranged between the baffle and the wrapping tape.

Preferably, the pull rope is formed by winding a plurality of groups of glass fiber wires into a whole.

Preferably, the outer wall of the lead is provided with an insulating layer.

Preferably, the wrapping tape is a rubberized glass ribbon or a mica tape.

The beneficial effects of the utility model are that: have the effect of preventing to lengthen the attenuate to the cable, improve the tensile effect of cable, the baffle setting is inside rubber filling layer, when tensile, can increase rubber filling layer lifting surface area, through stay cord pulling multiunit baffle, the baffle supports rubber filling layer and removes together, warp when preventing the cable pulling, the circular arc arch of baffle can support around band and polyurethane protective sheath, prevents that the cable from lengthening the attenuate.
