[0002] A wiring harness is a group of metal wires and cables tied together to carry signals and power between devices. It is a wiring component that connects various electrical devices in the automotive circuit. It is composed of an insulating sheath, terminal blocks, wires, and insulating wrapping materials. In order to extend the service life of the wiring harness, a rubber sleeve is used to protect the wiring harness. The rubber sleeve generally uses a nitrile rubber sleeve. Nitrile rubber has excellent oil resistance, wear resistance, and air tightness. These characteristics make it a suitable material for automotive wiring harness rubber sleeves. Nitrile rubber also has good heat resistance and adhesion, and can maintain stable performance in various environments. Therefore, in the automotive industry, nitrile rubber sleeves are widely used for insulation and protection of wiring harnesses.

[0003] For example, a Chinese patent with publication number CN215772355U discloses a rubber protective cover for wiring harnesses used in the front cabin of a car, comprising a sleeve and two connectors, the sleeve being a corrugated tube, with external threads respectively arranged at both ends of the sleeve, and internal threads matching the external threads arranged on the connectors, the connectors being threadedly connected to both ends of the sleeve; a clamping ring for fixing the wiring harness is arranged inside the connector; the utility model is easy and quick to install, and can fix the internal wiring harness, the wiring harness will not slide freely in the protective cover, thereby improving the protective effect of the protective cover on the wiring harness.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the above device is not convenient to disassemble after installation, and the whole device needs to be cut when disassembling, and usually the whole device needs to be cut, so it can only be used once and cannot be reused. At the same time, the above device can only be installed according to the fixed length when leaving the factory. When the length of the device needs to be extended, it needs to be connected through a connector, which makes the operation complicated, and when there is no connector, the two devices cannot be connected together. In view of this, we propose an automotive wiring harness rubber sleeve. Utility Model Content
