Description

Waterproof type vehicle-mounted connector Technical Field The invention relates to the connector field technology, in particular to a waterproof vehicle-mounted connector. Background The connector is an important carrier for carrying data and exchanging power, and the waterproof performance of the connector directly influences the functions and the service life of the product. With the rapid development of modern society and continuous progress of technology, people pay more attention to the safety problem of various electronic products, the quality and function requirements of the electronic products are also higher, and the importance of the connector as a carrier for carrying data and power exchange among devices and equipment, devices and machines, and machines is self-evident. The waterproof requirement of electronic products has become one of the basic elements of the quality of more and more electronic products, especially the connection device for carrying wired transmission data and power supply, and the waterproof quality directly affects the function and service life of the products. Meanwhile, with the diversification and the complexity of the application environments of various electronic products, the connector with the powerful waterproof function is applied to various fields around the world, such as security protection, communication, industry, aerospace navigation and military industry. Therefore, the improvement of the waterproof technology can ensure the equipment and the machinery more reliably, and people can use the electronic equipment and the machinery more safely. Most of the current connectors in the market are waterproof through sleeving waterproof rings, but waterproof performance is generally provided for the plugging ends of the connectors, and when external moisture enters the connector, the external moisture can smoothly enter the connector from the inside to the device to which the connector belongs, so that the device is damaged. Therefore, there is a need for improvements over existing waterproof connectors. Disclosure of Invention In view of the above, the present invention aims at overcoming the drawbacks of the prior art, and its main objective is to provide a waterproof vehicle-mounted connector, which can effectively solve the problem that the existing waterproof connector only provides waterproof performance for the plugging end of the connector, and external moisture cannot be prevented from entering the interior of the device to which the connector belongs after entering the interior of the connector.
