[0002] A wire harness is the overall equipment that provides services for a certain load source group, such as relay lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship among traffic volume, call loss, and wire harness capacity. Therefore, the wire harness is an important basic concept in traffic theory.

[0003] After retrieval, a wire harness disclosed in a Chinese patent with the publication number CN218039937U includes a plurality of wire harnesses arranged side by side, a connector housing, and a wire harness rubber housing. The connector housing is composed of an upper housing and a lower housing, and a raised button is arranged on the outer side of the connector housing. In the utility model, a connector housing and a water-proof ring are arranged on a wire harness. Through the detachable connector housing structure of the upper and lower housings, the wire harness rubber housing is clamped and limited, and the wire harness is arranged to pass through, reducing the possibility that the middle wire harness is easily pulled out individually during the insertion and extraction of the connection heads of multiple wire harnesses, resulting in the wire core of the wire harness being damaged or broken, thereby ensuring the function of data conduction of the wire harness.

[0004] Although the above patent can ensure the function of data conduction of the wire harness, the wire harness in the above patent does not have wear resistance. When the wire harness is used for a long time, it is easy to cause the wire harness to be damaged and broken. For this reason, we provide a wear-resistant wire harness to solve the above problems.

One end of the cable 205 is fixedly connected to the inside of the first fixing groove 8. The cable 205 in the second fixing box 17 can be fixed by the fifth bolt 18, preventing the cable 205 from loosening during long-term use and causing a short circuit of the cable 205. The cable 205 is fixed in the first fixing groove 8, facilitating the fixing of the cable 205.

[0032] Please refer to Figure 1, the outer circumferential surface of the fifth bolt 18 is sleeved inside the second spring 19. One end of the second spring 19 is fixedly connected to the upper surface of the second fixing box 17. The insertion block 13 is stuck in the fixing block 7, which can connect the cable wires 205 on both sides together. By pushing the second sliding clamp 20 inside the second fixing box 17 with the fifth bolt 18, the cable wires 205 are fixed, playing a fixing role to prevent the cable wires 205 from falling off. On one side of the insertion block 13, a second fixing groove 15 is provided. The inside of the second fixing groove 15 is slidably connected to one side of the second fixing plate 16. The upper surface of the second fixing plate 16 is rotatably connected to one end of the fourth bolt 14. The fourth bolt 14 is threadedly connected to the insertion block 13. The insertion block 13 can be clamped by the fixing block 7, which is convenient for connecting the cable wires 205 on both sides. By driving the second fixing plate 16 with the fourth bolt 14 to fix the cable wires 205 inside the second fixing groove 15, the cable wires 205 on the other side can perform transmission work.

[0033] Please refer to Figure 4 , in the middle of one side of the fixing block 7, a first fixing groove 8 is provided. The inside of the first fixing groove 8 is slidably connected to the first fixing plate 11. The upper surface of the first fixing plate 11 is rotatably connected to the third bolt 9. The third bolt 9 is threadedly connected to the fixing block 7. The connecting block 6 can fix the first fixing box 1 and the connecting block 6 together, and the cable wires 205 can be inserted into the first fixing groove 8. By pushing the first fixing plate 11 with the third bolt 9 to fix the cable wires 205, it can prevent the cable wires 205 from loosening during use.

Inside the first fixing box 1, a first sliding groove 10 is provided. The surface of the first sliding clamp 3 is slidably connected to the inside of the first sliding groove 10. The upper surface of the first sliding clamp 3 is rotatably connected to the second bolt 5. The second bolt 5 is threadedly connected to the upper surface of the first fixing box 1. By the first sliding groove 10 provided inside the first fixing box 1, the second bolt 5 can push the first sliding clamp 3 to fix the cable wires 205. Due to the effect of the first sliding clamp 3, it can prevent the cable wires 205 from falling off and causing a short circuit during use. The second bolt 5 rotates inside the first fixing box 1, playing a fixing role.

[0035] Please refer to Figure 2, on one side of the first fixing box 1, there is a wire harness body 2. The wire harness body 2 includes a cable 205. The outer circumferential surface of the cable 205 is fixedly connected to the inside of the fixing layer 204. The outer circumferential surface of the fixing layer 204 is fixedly connected to the inside of the flame retardant layer 203. The outer circumferential surface of the flame retardant layer 203 is fixedly connected to the inside of the buffer layer 202. The outer circumferential surface of the buffer layer 202 is fixedly connected to the inside of the wear-resistant protective layer 201. The wear-resistant protective layer 201 can protect the surface of the wire harness, preventing the wire harness from being worn and exposed when sliding back and forth. And the flame retardant layer 203 can protect the cable 205. When a short circuit occurs in the cable 205 and causes a fire, it can play a role in flame retardancy, effectively preventing the cable 205 from catching fire. The buffer layer 202 can buffer the surface of the cable 205, preventing the cable 205 from being damaged by collision.

[0036] Working principle: The fixing layer 204 can fix the cable 205 to prevent the cable 205 from being wound together and causing the cable 205 to heat up. The flame retardant layer 203 can prevent fire for the cable 205, playing a role in flame retardancy and effectively preventing the cable 205 from catching fire. The buffer layer 202 can buffer the wire harness body 2, preventing the cable 205 from being broken when being collided. The wear-resistant protective layer 201 protects the wire harness body 2, preventing the cable 205 from being damaged during long-term use and causing the cable 205 to short-circuit, resulting in the wire harness body 2 being unable to be used. After the cable 205 is inserted into the first fixing box 1, the second bolt 5 is used to push the first sliding clamp 3 to slide up and down in the first chute 10, which can fix the cable 205 and facilitate the maintenance of the cable 205. The first fixing box 1 is fixed to the connecting block 6 by the first bolt 4, enabling the cable 205 to be fixed in the first fixing groove 8. The third bolt 9 is used to push the first fixing plate 11 to fix the cable 205 in the first fixing groove 8, preventing the cable 205 from loosening during use and causing the cable 205 to short-circuit. By inserting the insertion block 13 into the fixing block 7, the cable 205 on both sides can be connected together, facilitating transmission. The fourth bolt 14 can fix the cable 205 in the second fixing groove 15, and the second fixing box 17 fixes the cable 205 on the other side, facilitating the fifth bolt 18 to push the second sliding clamp 20 to fix the cable 205 on the other side, effectively improving the wear resistance of the wire harness.
