DETAILED DESCRIPTION
[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0030] like Figures 1 to 8 As shown, a wire body 1 with high waterproofness, high tensile strength and high tolerance in one embodiment of the utility model has a swing stress relief structure, including: a wire body 1.
[0031] like Figure 1 As shown, the wire body 1 is composed of a wire harness outer layer 101, a Kevlar core wire 102 and a plurality of conductive core wires 103. The wire harness outer layer 101 is sheathed on the outside of the Kevlar core wire 102 and the plurality of conductive core wires 103. The Kevlar core wire 102 and the plurality of conductive core wires 103 are sheathed and insulated by the wire harness outer layer 101.
[0032] Specifically, the size and shape of the harness outer layer 101 can be designed according to specific application scenarios and requirements, so that the harness outer layer 101 can accommodate components such as the Kevlar core wire 102 and the conductive core wire 103, and has good waterproof and tensile properties.
[0033] Preferably, the outer layer 101 of the wiring harness is one of polyethylene, polyurethane or silicone, so as to make the outer layer 101 of the wiring harness have good chemical resistance and wear resistance, and ensure the use stability of the outer layer 101 of the wiring harness in harsh environments.
[0034] like Figures 1 to 4As shown, one end of the wire body 1 is fixedly assembled with a copper buckle 2. The copper buckle 2 is used to assemble and limit the wire body 1, thereby ensuring the connection stability of the wire body 1.
[0035] like Figures 1 to 4 As shown, the copper buckle 2 is composed of a copper buckle body 201 and a pair of limiting platforms 202, and the pair of limiting platforms 202 are integrally formed at both ends of the copper buckle body 201. The pair of limiting platforms 202 play a role in winding and limiting the copper buckle body 201, reducing the risk of the Kevlar core wire 102 slipping during the winding process.
[0036] It is worth noting that the Kevlar core wire 102 is wound around the outside of the copper buckle body 201. By winding and bundling the Kevlar core wire 102 around the outside of the copper buckle body 201, the stability of the copper buckle 2 in assembling and limiting the wire body 1 is improved, the safety and stability of the internal components of the wire body 1 are ensured, and the tensile resistance of the wire body 1 is improved.
[0037] Specifically, the copper buckle 2 is made of copper alloy. By using copper alloy to prepare the copper buckle 2, the copper buckle 2 has good resistance to deformation and corrosion. The connection method between the copper buckle 2 and the wire body 1 is riveting, which ensures the assembly stability of the copper buckle 2 and the wire body 1.
[0038] like Figures 1 to 6 As shown, the outer side of the copper buckle 2 is snap-fitted with a flexible net tail 3. The flexible net tail 3 plays the role of assembling and shock-absorbing protection for the wire body 1.

[0043] Among them, the flexible net tail 3 can be tightly combined with the wire harness outer layer 101, the copper buckle body 201 and the net tail assembly part 302 by injection molding, thereby reducing the impact of external swinging and pulling on the wire body 1, and enhancing the vibration resistance and swing resistance of the wire body 1.
[0044] It is worth noting that the design of the assembly plastic part 4 should take into account the size and shape of the wiring harness to ensure that the wiring harness can be fully accommodated and effectively protected.
[0045] Specifically, the assembled plastic part 4 is one of polypropylene, polyethylene or polycarbonate. The assembled plastic part 4 has good insulation, wear resistance and corrosion resistance. The end of the net tail limiter 303 away from the net tail assembly part 302 is engaged with the inner plane of the plastic part body 401. By engaging the net tail limiter 303 with the plastic part body 401, it is convenient to maintain the overall shape and structural stability of the wire harness.

The assembled plastic part 4 and the flexible net tail 3 are sealed and waterproofed by the waterproof ring 5, so as to ensure that the wire body 1 has good waterproof performance.
[0048] It is worth noting that the size and shape of the waterproof ring 5 match the sealing groove on the outside of the net tail assembly part 302 , ensuring that the waterproof ring 5 can be firmly mounted on the outside of the net tail assembly part 302 .
[0049] The waterproof ring 5 is made of rubber, silicone or polyurethane, so as to ensure the sealing and corrosion resistance of the waterproof ring 5.
[0050] During specific assembly, the copper buckle 2 is sleeved on the outside of the wire body 1, and the copper buckle body 201 is fixed on the outside of the wire body 1 by riveting. At the same time, the Kevlar core wire 102 can be wound on the outside of the copper buckle body 201, the flexible net tail 3 is sleeved on the outside of the wire body 1, and the copper buckle 2 is installed in the assembly limit groove in the net tail assembly part 302. The assembly plastic part 4 is sleeved on the outside of the net tail assembly part 302 by the mutual engagement of the assembly clamp 402 and the outer engagement limit groove of the net tail assembly part 302. At the same time, by assembling the waterproof ring 5 between the net tail assembly part 302 and the assembly clamp 402, the waterproof performance of the wire body 1 is guaranteed.
