[0002] With the continuous improvement of people's living standards, while the car becomes our main means of transport, people's quality requirements for cars also become higher and higher, which makes automobile manufacturers need to improve their product quality and product level in the process of producing cars. However, due to the fact that there are still many defects in the technology of the product, some automobile parts are not suitable for the development of automobile technology, so they need to be improved. The automobile wiring harness connects various vehicle electrical appliances, and is connected with the tail door through the layout of the wiring through the vehicle body. However, a part of it is exposed outside, and the door needs to be continuously opened and closed. The traditional components cannot withstand the damage to the wiring harness caused by frequent door opening and closing. For a micro van, due to the influence of the vehicle body structure, the space distance between the two states of the tail door when it is closed and completely opened will vary greatly on different models. The existing wiring harness connector is prone to over-torsion in the opening and closing door state, which may cause the connector to break.

[0003] After searching, the existing patent (publication number: CN219382376U) discloses a rubber connector for automobile wiring harness, which is used for the connection between the tail door and the vehicle body of a micro van.
