Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a temperature-resistant tensile waterproof wear-resistant silicone rubber sheathed cable. Referring to fig. 1, the temperature-resistant tensile waterproof wear-resistant silicone rubber sheathed cable comprises:

a conductor 100, an insulating layer 200 covering the conductor 100, and a protective layer 400 for protecting the conductor 100.

Referring to fig. 1, a wire core 110 of a conductor 100 is an ultra-fine sixth conductor (the ultra-fine sixth conductor described in this application is a wire using specification parameters of a monofilament diameter of a sixth conductor wire core specified in GB/T3956-2008), and is formed by twisting silver-plated silver-copper alloy, and after silver plating, the conductivity is better, and the silver-copper alloy has good mechanical properties, and excellent tensile and bending resistance properties. In the embodiment of the present application, there are several conductors 100, and each conductor 100 has a core 110 covered with an insulating layer 200. The insulation layer 200 is made of FEP fluoroplastic, which is the toughest fluoroplastic, has similar characteristics to those of polytetrafluoroethylene, has good processability, and is convenient to machine and form while having a good insulation effect. The plurality of conductors 100 are twisted to form the twisted conductor 300, and the stranding pitch multiple of the twisted conductor 300 is 15 times, so that the bending performance is good.

Referring to fig. 1 and 2, the protective layer 400 for protecting the conductor 100 includes a wrapping layer 410, a tensile bending-resistant layer 420, and a temperature-resistant layer 430 in sequence from inside to outside. The wrapping layer 410 is formed by spirally winding the raw material tape on the outer side of the stranded conductor 300, so that each conductor 100 is tightly attached, and the roundness of the cable is ensured.

Referring to fig. 1 and 2, the first wire 421 is an aramid fiber, the second wire 422 is a silver-plated copper wire, and the aramid fiber and the silver-plated copper wire are woven and coated in an 8 shape on the wrapping layer 410 by a weaving machine to form the tensile bending-resistant layer 420. Because aramid fiber has good performances such as flexibility, high strength, high wear resistance, the coating of the tensile resistant layer 420 that is woven with aramid fiber and silver-plated copper wire in a staggered manner outside the covering 410 on the one hand further guarantees the roundness of the stranded conductor 300, and on the other hand has improved the tensile resistance and the resistant bending property of the cable and has played a shielding role simultaneously.

Referring to fig. 1, the temperature-resistant layer 430 is a high tear-resistant silicone rubber layer. The high tearing-resistant silica gel is prepared by gradually adding fumed silica and other auxiliary materials into raw rubber, and compared with precipitated silica used in common mixed silicone rubber, the fumed silica has higher fineness, so that the silicone rubber has better strength in mixing and molding.

The implementation principle of the temperature-resistant tensile waterproof wear-resistant silicone rubber sheathed cable provided by the embodiment of the application is as follows: firstly, a plurality of silver-plated silver-copper alloy wires passing through a wire drawing machine are stranded by a stranding machine to form a conductor 100, and then FEP fluoroplastic is extruded and coated on the conductor 100 by an extruding machine to form an insulating layer 200. Several conductors 100 with insulation layers 200 are stranded by a stranding machine to form a stranded conductor 300. The twisted conductor 300 is wound with the raw material tape through the wrapping machine, and the winding of the raw material tape further fastens the joint between the conductors 100, so that the roundness of the twisted conductor 300 is kept. The wrapped stranded conductor 300 passes through a braiding machine, and the aramid fiber and the silver-plated copper wire are braided and coated on the outer side of the cable in a staggered mode through the braiding machine to form the tensile bending-resistant layer 420. And then coating the high-tear-resistance silicon rubber on the tensile and bending-resistant layer 420 through a silicon rubber extruder to form a temperature-resistant layer 430, and cooling to finish the cable processing.
