[0002] With the development of society and the rapid progress of economy, more and more cars are entering the homes of ordinary consumers. The competition in the automobile industry is relatively fierce, and consumers have higher requirements for the reliability of automobiles. Although modern automobiles are constantly improving in overall performance and configuration, the role of small automobile parts on automobiles cannot be ignored. Automobile front door wiring harness sheath is used to connect the front door of the car and the car body. The wiring harness passes through the wiring harness sheath to prevent the wear of the automobile line. It prevents mud and water mixture from entering the door and body of the car during natural use, causing short circuit of automobile electrical appliances, and prevents electrical failure and fire in the car.

[0003] The existing automobile front door wiring harness sheath is made of rubber material, and the rubber part and the sheet metal are connected by a snap-on method. The front door of the car is a component that is often opened and closed, so the two ends of the wiring harness sheath are required to be stably mounted on the sheet metal and have good flexibility and retractability. The connection between the rubber part and the sheet metal is not firm and stable, and it is easy to fall off the sheet metal, which is not conducive to the protection of the wiring harness. Under severe automobile vibration, the wiring harness sheath is easily damaged, does not play a protective role, and has a short service life. Summary of the invention
