According to the progress and influence of the technology era, the application of many electronic and electrical products not only improves work efficiency, shortens work time, but also makes the work quality more excellent, and through the convenience and practicality of electronic and electrical products, at work, There are considerable benefits in life. When using various electronic and electrical products, the transmission of various software operation signals, data, audio and video signals, etc. is a very important operation, and must be carried out by different electronic and electrical signals. It can be used for the processing and operation of various related operations, and the wires and electrical connectors used to transmit signals when transmitting various electronic and electrical signals are the most direct and commonly used equipment, through various types of wires. The electrical connection of the electrical connector enables stable and fast transmission of electronic and electrical signals, and also enhances the operation, processing time and function of electronic and electrical products.

Moreover, the existing electrical connectors are often used in outdoor places, so if the electrical connector itself is not designed to be waterproof, it is susceptible to long-term rain, resulting in electricity. The inside of the connector is wet, water seepage, etc., and the connection between the connector and the wire is mostly made of metal material as a signal. If the inside of the connector is wet and water seepage, the metal material may be easily wetted or short-circuited. In order to damage or destroy the transmission function and lose its effect, some manufacturers have developed a waterproof connector for waterproofing in order to solve the problem of waterproofing the electrical connector.

A threaded section B3 is arranged on the inner side of the opening, and the waterproofing glue C on the joint connector A is filled in the receiving groove B2, so that the waterproof glue C can be used to achieve the waterproof effect, thereby avoiding mutual conduction between the plurality of metal terminals A1. In the case of short circuit, and when the conventional waterproof connector is used for plugging and unloading with the connector of the opposite type, the threaded section B3 can be used to interfere with the waterproof adhesive C, thereby improving the gap between the sleeve B and the waterproof adhesive C. The bonding force, in turn, reduces the occurrence of the connector A coming out of the housing space B1 of the sleeve B. However, since the thread segment B3 is disposed on the inner wall surface of the receiving groove B2 and extends to the opening, if the user inserts The force at the time of the connection is too large, or the force of the sleeve B is rotated. When it is too large, it is easy to cause the connector A to be rotated, so that the connector A is disengaged from the storage space B1 of the sleeve B along with the thread segment B3, thereby further reducing the waterproof effect of the conventional waterproof connector. If the conventional waterproof connector is damaged or destroyed, it cannot be used again, which causes inconvenience in use.
