[0017] Example: See Figure 1-2 , a wear-resistant charging pile cable, comprising: a plurality of cable cores 1, a high-strength wear-resistant outer protective structure being installed on the plurality of cable cores 1;

[0018] The high-strength wear-resistant outer protective structure includes: a wire core support 2, a winding layer 3, an inner protective layer 4, a structural reinforcement layer 5, a steel belt armor 6, an outer protective layer 7 and a wear-resistant layer 8;

[0019] Several cable cores 1 are installed on the core bracket 2, the winding layer 3 is wrapped around the outside of the several cable cores 1, the inner protective layer 4 is wrapped around and covered on the outer wall of the winding layer 3, the structural reinforcement layer 5 is wrapped around and covered on the outer wall of the inner protective layer 4, the steel belt armor 6 is arranged on the outside of the structural reinforcement layer 5, the outer protective layer 7 is arranged on the outer wall of the steel belt armor 6, and the wear-resistant layer 8 is wrapped around and covered on the outer wall of the outer protective layer 7.

[0020] In the specific implementation process, further, an insulating layer 9 is provided on the outer wall surface of the plurality of cable cores 1 .

[0021] In the specific implementation process, further, a filling layer 10 is arranged between the plurality of cable cores 1 and the winding layer 3 .

[0023] In the specific implementation process, further, a sleeve slot 12 is opened on the wire core bracket 2.

[0024] In the specific implementation process, further, a reinforcing steel wire 13 is arranged inside the outer protective layer 7 .

[0025] It should be noted that the cable core 1 is the core part of the cable, which is responsible for transmitting electrical energy and realizing power transmission connectivity. At the same time, several cable cores 1 are combined and fixed by a core bracket 2, which is used to support and fix the cable cores 1 to ensure that they are arranged in order inside the cable to avoid mutual entanglement or dislocation. The winding layer 3 arranged on the outside of the cable core 1 tightly wraps the inside to increase the tensile strength and bending resistance of the cable. The inner protective layer 4 is located outside the winding layer 3 to isolate the direct influence of the external environment on the cable core 1. It has good electrical insulation performance and certain mechanical strength. The structural reinforcement layer 5 is provided to further enhance the mechanical strength of the cable. It can resist external pressure and impact, and cooperate with the reinforced steel wire 13 to ensure enhanced protection effect. The steel belt armor 6 provides safe protection for the entire interior and provides additional mechanical protection, especially against external mechanical pressure and puncture of sharp objects. The outer protective layer 7 further enhances the protection effect of the cable, while avoiding damage to the cable caused by chemical corrosion after external moisture. The wear-resistant layer 8 is arranged outside the outer protective layer 7 and directly contacts the external environment. The wear-resistant layer is made of highly wear-resistant material, which can effectively resist the wear caused by frequent plugging and unplugging, dragging, etc. during the use of the charging pile, and protect the overall structure of the cable from damage.
