[0002] With the wide application of electronic devices, the requirements for electrical connection components are getting higher and higher, especially for devices working outdoors or in humid environments. As an indispensable part of the electrical system, the performance of wire harness plugs directly affects the stability and safety of the entire system. Especially in application scenarios involving underwater, rainy days or other humid environments, ordinary wire harness plugs often cannot meet the waterproof requirements, easily leading to short circuits and even equipment damage.

[0003] Existing waterproof wire harness plugs usually use a variety of independent components to achieve the waterproof function, such as setting sealing rings or tape winding on the outer ring of the docking section and the outer ring of the incoming line section as well as the incoming line hole of the plug. However, these methods have certain limitations:

[0004] 1. Complex assembly: The multi-component design increases the steps and time costs in the assembly process, and each component needs to be installed separately, increasing the possibility of errors.

[0005] 2. Low reliability: The sealing ring or other external sealing materials may age or lose elasticity over time, thus reducing the waterproof effect; in addition, in harsh conditions such as large temperature changes or mechanical vibration environments, it is also easy to cause sealing failure.

[0006] Therefore, it is necessary to develop a new structure of waterproof wire harness plug, which can simplify the assembly process, reduce costs, and improve the reliability and stability of long-term use while ensuring good waterproof performance. Content of the Utility Model
