Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0025] like Figures 1-4As shown, the utility model provides a technical solution: a pull-resistant automotive waterproof wiring harness, comprising: a tensile mechanism 1, an auxiliary mechanism 2 is provided on the outside of the tensile mechanism 1, the tensile mechanism 1 comprises a hollow sheath 11, a U-plate 14 is provided on the inside of the hollow sheath 11, the inner side of the hollow sheath 11 is fixedly connected to the bottom side of the U-plate 14, an X-plate 13 is provided on the inside of one end of the U-plate 14, the inner side of one end of the U-plate 14 is movably connected to one end of the X-plate 13, the other end of the X-plate 13 is provided with a U-plate 2 111, the other end of the X-plate 13 is movably connected to the inner side of one end of the U-plate 2 111, the bottom side of the U-plate 2 111 is fixedly connected to the inner side of the hollow sheath 11, the inner wall of the hollow sheath 11 is provided with a wiring harness body 12, the inner wall of the hollow sheath 11 is fixedly connected to the outer side of the wiring harness body 12 Fixed connection, an inner plate 110 is provided on the inner side of the hollow sheath 11, and the inner side of the hollow sheath 11 is fixedly connected to one end of the inner plate 110, and a movable block 18 is provided on one end of the inner plate 110, and one end of the inner plate 110 is movably connected to the inner side of the middle end of the movable block 18, and a reaction plate 19 is provided on one end of the movable block 18, and one end of the movable block 18 is fixedly connected to one end of the reaction plate 19, and the outer side of the reaction plate 19 is in contact with the inner side of the hollow sheath 11, and a protrusion 17 is provided on one end of the movable block 18, and one end of the movable block 18 is in contact with one end of the protrusion 17 in a transverse movement, and a C-plate 16 is provided on one end of the protrusion 17, and one end of the protrusion 17 is fixedly connected to one side of the C-plate 16, and an arc-shaped plate 15 is provided on one end of the C-plate 16, and one end of the C-plate 16 is fixedly connected to one end of the arc-shaped plate 15.

[0026] In this embodiment, when the anti-pull automobile waterproof wiring harness is in use, a hollow sheath 11 is designed on the outside of the wiring harness body 12. In order to increase the anti-pull ability of the wiring harness through the hollow sheath 11, a U-plate 14 and a U-plate 2 111 are installed on the hollow sheath 11, and the two are connected by an X-plate 13.

Combined with the waterproof layer 21 and the insulating layer 22, comprehensive protection can be achieved. This structure provides a higher standard of protection for internal electrical components, is suitable for electronic products or cables exposed to harsh environments, and helps to improve the reliability and safety of the system.
