Description

Stretch-proofing cable Technical Field The utility model relates to the technical field of cables, in particular to a stretch-proof cable. Background The cable is a generic term of articles such as optical cables and electric cables, has a plurality of uses, is mainly used for controlling multiple functions such as installation, connection equipment, power transmission and the like, and is an indispensable article common in daily life. The existing cable is mostly coated with the cable core inside by using a multi-layer structure, in the use process, the tensile strength is poor, and when large tensile force occurs at two ends in the use process, displacement occurs between layers, so that the cable is deformed, and the use effect of the later stage of the cable is reduced. Disclosure of utility model In order to solve the problems, the present utility model provides a stretch-proof cable. The technical aim of the utility model is achieved through the following technical scheme that the stretch-resistant cable comprises a plurality of cable cores, insulating layers are sleeved on the outer walls of the cable cores, protection layers are jointly arranged on the outer walls of the cable cores, a wrapping sheath is arranged on the outer walls of the protection layers, reinforcing cores are arranged in the protection layers, filling layers are jointly arranged among the reinforcing cores, the cable cores and the protection layers, and the reinforcing cores, the cable cores, the protection layers and the filling layers are produced by wrapping. Through adopting above-mentioned technical scheme, when the cable main part is in use, the electric current is transmitted through a plurality of cable cores, carries out the pattern through insulating layer and filling layer between a plurality of cable cores in the course of the work, and then makes a plurality of cable cores independently work to the practicality of device has been improved. In addition, in the use, form through wrapping production between strengthening core, cable core, protective layer and the filling layer, when using, strengthen the core and improved cable main part's tensile strength, and then reduced the probability that takes place to warp when cable main part uses to cable main part's result of use has been improved. Further, a plurality of convex rings are distributed on the outer wall of the protective layer in an array mode, the convex rings and the protective layer are fixed mutually, the protective layer is made of crosslinked polyethylene, and the convex rings are made of crosslinked polyethylene. Through adopting above-mentioned technical scheme, when using, the protective layer is made to crosslinked polyethylene material and protruding circle has good elasticity, and then makes the frictional force between protective layer and the parcel crust increase, and then has reduced the probability that protective layer and parcel crust take place the displacement when using to the probability that cable main part takes place to warp has been reduced. In addition, as shown in fig. 2, the convex rings are arranged on the outer wall of the protective layer in a plurality of parallel arrays, and the convex rings improve the roughness of the surface of the protective layer, so that the friction between the protective layer and the wrapping sheath is further improved, the probability of displacement of the protective layer and the wrapping sheath is further reduced, and the probability of deformation of the cable main body is further reduced. In addition, the crosslinked polyethylene material has good heat resistance, insulativity, mechanical property and corrosion resistance, so that the probability of damage of the cable main body during use is reduced, and the service life of the device is prolonged. Further, a plurality of anti-skidding lines are arranged on the outer wall of the reinforced core in an array mode, and the filling layer is made of glass fiber materials. Through adopting above-mentioned technical scheme, the filling layer that glass fiber material was made has good tensile properties and still has good elasticity and dimensional stability simultaneously, and then has further improved cable main body's stretch-proofing nature and still can restore the original form after cable main body takes place to improved cable main body's result of use.
