[0004] The above technical solution can effectively improve the structural strength of automotive wiring harnesses, while meeting the requirements of light weight. It also has a simple structure and high scalability. However, in the above technical solution, the automotive wiring harness connects to the automotive terminal. Since the automotive wiring harness contains a lot of connecting wires, it is inconvenient to wind up the excess wires, which can easily cause the automotive wiring harness to become tangled, making it inconvenient to connect and use the automotive wiring harness.

[0005] Therefore, we propose a lightweight automotive wiring harness to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4This embodiment provides a lightweight automotive wiring harness, which includes a wiring harness body 1. The wiring harness body 1 is made of a lightweight material, which facilitates the use of the lightweight automotive wiring harness. A winding box 8 is provided on the outside of the wiring harness body 1. Two guide boxes 10 are fixedly connected to the outer surface of the winding box 8. Each wiring harness body 1 is slidably connected to the inside of the guide box 10. Using the guide box 10, the wiring harness body 1 can be stably wound into the inside of the winding box 8, which facilitates the connection of the lightweight automotive wiring harness to the vehicle terminal.

[0024] The rewind box 8 is externally threaded with an upper cover 9. The upper surface of one set of wire harness bodies 1 is in contact with the bottom surface of the upper cover 9. Each wire harness body 1 has a connecting connector 2 fixedly connected to its left and right ends. Each connecting connector 2 has a baffle 4 fixedly connected to its outer surface. The connecting connector 2 is used to connect to the vehicle terminal, thereby facilitating the connection of the lightweight automotive wire harness to the vehicle terminal. The baffle 4 also facilitates the installation of the connecting connector 2.

[0025] Two connecting connectors 2 are fixedly connected to each other on their opposite sides. Each of the two connecting connectors 3 has equally spaced connecting holes 5 on its opposite sides. The connecting connectors 3 are snapped into the connection point of the vehicle terminal, and the connecting holes 5 are connected to the vehicle terminal, thereby improving the connection stability between the lightweight vehicle wiring harness and the vehicle terminal.

[0026] A winding rod 11 is rotatably connected inside the top cover 9. The winding rod 11 is rotatably connected inside the winding box 8. The outer surfaces of several wire harness bodies 1 are fixedly connected to a limiting connecting cylinder 6. The inner wall of the limiting connecting cylinder 6 is in contact with the outer surface of the winding rod 11. The upper surface and the bottom surface of the limiting connecting cylinder 6 are in contact with the bottom surface of the top cover 9 and the inner bottom wall of the winding box 8, respectively. The limiting connecting cylinder 6 can be conveniently connected to the outer surface of the wire harness body 1, thereby facilitating the winding of the wire harness body 1.

[0027] The inner wall of the limiting connecting cylinder 6 is provided with winding slots 7 arranged at equal intervals. The outer surface of the winding rod 11 is fixedly connected with winding pins 12 arranged at equal intervals. Each winding pin 12 is engaged inside the winding slot 7. By engaging the winding pin 12 into the winding slot 7, the wire harness body 1 can be stably wound into the winding box 8, thereby further facilitating and stably winding the wire harness body 1.

[0028] The top of the winding rod 11 is fixedly connected to an upper plate 16. The upper surface of the upper plate 16 has two sliding holes 17. The upper surface of the upper cover 9 is fixedly connected to a limiting ring 14. The upper surface of the limiting ring 14 has limiting grooves 15 arranged at equal intervals. Each sliding hole 17 is slidably connected to a limiting pin 20. The outer surface of each limiting pin 20 is threadedly connected to the inside of the limiting groove 15. The bottom end of each limiting pin 20 passes through the sliding hole 17 and the limiting groove 15 and contacts the surface of the upper cover 9. Each limiting pin 20 is fixedly connected to a pulling block 21. Each pulling block 21 is rotatably connected to a pulling ring 22. By manually holding the pulling ring 22, the pulling block 21 can be easily rotated and the limiting pin 20 can be pulled, thus facilitating the use of the limiting pin 20.

[0029] Each limiting pin 20 has a limiting nut 13 threadedly connected to its outer surface. The bottom surface of each limiting nut 13 is in contact with the upper surface of the upper plate 16. Each limiting nut 13 has a first rotating handle 18 fixedly connected to its outer surface. The upper plate 16 has a second rotating handle 19 fixedly connected to its outer surface. By manually holding the first rotating handle 18, the limiting nut 13 can be easily rotated. By manually holding the second rotating handle 19, the upper plate 16 can easily wind up the automotive wiring harness.

[0030] The working principle of this utility model is as follows: When using the lightweight automotive wiring harness, if it is necessary to wind it up and connect it to the automotive terminal, firstly, manually hold the first rotating handle 18 to twist the limiting nut 13, so that the limiting pin 20 can slide in the sliding hole 17. Then, manually hold the pull ring 22, and through the pull block 21, rotate the limiting pin 20 in the limiting groove 15, so that the limiting pin 20 can be pulled out from the limiting groove 15, making it convenient for the winding rod 11 to rotate in the winding box 8. Manually holding the second rotating handle 19 makes it convenient for the upper top plate 16 to drive the winding rod 11 to rotate. Since the limiting connecting cylinder 6 fixed outside the wiring harness body 1 is set on the winding rod... The wire harness body 1 is attached to the outside of the winding rod 11 and is secured to the winding slot 7 by the winding post 12. This allows for easy manual pulling of both ends of the wire harness body 1, enabling the wire harness body 1, which is wound outside the winding rod 11, to unfold along the guide box 10. This extends the wire harness body 1, making it easier for the snap-fit ​​connector 3 on the side of the connector 2 to snap onto the connection point of the vehicle terminal. This facilitates the connection of the lightweight automotive wire harness to the vehicle terminal. After the snap-fit ​​connector 3 on the side of the connector 2 is secured to the connection point of the vehicle terminal, the excess connecting wires of the lightweight automotive wire harness need to be manually wound up. By repeating the above steps, the lightweight automotive wire harness can be used conveniently.
