Description

TECHNICAL FIELD

[0001] The application relates to the technical field of connectors, in particular to a quick-pluggable and wear-resistant automobile Ethernet connector. BACKGROUND

[0002] With the rapid development of modern automobile technology, especially the rapid progress in the fields of Internet of Vehicles, autonomous driving and electrification, the connectivity between the internal network of the automobile and other devices becomes crucial. As a key component connecting the internal network of the automobile, sensors, ECUs (Electronic Control Units) and external infrastructure, the performance and reliability of the automobile Ethernet connector directly affect the data transmission efficiency, stability and safety of the entire automobile system.

[0003] Although the automobile Ethernet connectors on the market meet the demand of data transmission to some extent, there are still deficiencies in quick plugging and wear resistance. In the process of frequent plugging and long-term use, the connector may have problems such as poor contact, signal attenuation and even damage, which seriously affect the stability and reliability of data transmission, and cannot be quickly plugged. If it is stuck, it is inconvenient to plug, so there are certain disadvantages.

The male sleeve and the female sleeve are detachably connected through a self-locking structure. The male sleeve is provided with a male terminal, and the female sleeve is provided with a female terminal which is inserted and matched with the male terminal and can avoid relative sliding with the male terminal. The female sleeve is provided with a female terminal which is inserted and matched with the male terminal, and the female terminal can avoid relative sliding with the male terminal. After multiple plugging cycles of the connector terminal, the terminal bonding area coating will not be worn out because of no relative sliding, and the electrical contact performance will be continuously maintained. The terminal bonding area contact resistance and current circulation temperature rise will not increase, solving the technical problems of wear and tear of the terminal bonding area coating and reduction of electrical contact performance, increase of contact resistance and current circulation temperature rise after multiple plugging cycles of the connector terminal.

[0005] The above document only realizes quick plugging by setting the female terminal and the male terminal, and then realizes wear resistance by coating. However, this plugging method only relies on single clamping for connection, and cannot ensure the reliability of plugging from multiple directions. Utility model content
