Description

Technical Field

[0001] This invention relates to the field of connectors, and in particular to a waterproof automotive connector. Background Technology

[0002] Connectors are crucial carriers of data and power exchange, and their waterproof performance directly impacts product functionality and lifespan. With the rapid development of modern society and continuous technological advancements, people are increasingly concerned about the safety of various electronic products, and the quality and functional requirements of these products are also rising. As the carrier of data and power exchange between devices, machines, and other equipment, the importance of connectors is self-evident. Waterproofing has become a fundamental element of quality for an increasing number of electronic products, especially for connectors that carry wired data and power transmissions; their waterproof quality directly affects product functionality and lifespan. Furthermore, with the diversification and complexity of application environments for various electronic products, connectors with strong waterproof capabilities will be used in various fields worldwide, such as security, communications, industry, aerospace, marine, and military. Therefore, improvements in waterproofing technology will provide more reliable guarantees for equipment and machinery, making the use of electronic devices and machinery safer.

[0003] Most connectors on the market currently achieve waterproofing by using waterproof rings, but this typically only provides waterproofing to the connector's mating ends. When external moisture enters the connector, it can easily seep into the device it's connected to, potentially causing damage. Therefore, it's necessary to improve existing waterproof connectors. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the prior art, and its main objective is to provide a waterproof vehicle connector that effectively solves the problem that existing waterproof connectors only provide waterproof performance at the connector's insertion end, and cannot prevent external moisture from entering the internal parts of the device to which the connector belongs after it has entered the connector.
