[0030] Between the plugging cavity 11 and the fixing cavity 12 of the housing 1, there is an installation panel 13, and installation holes 131 are provided on the installation panel 13. Specifically, a sealing groove 132 is provided on the outer periphery of the fixing cavity 12 of the installation panel 13, and a sealing member 133 is installed on the sealing groove 132. In this embodiment, by providing the installation panel 13 between the plugging cavity 11 and the fixing cavity 12 of the housing 1, providing the installation holes 131 on the installation panel 13, and then installing the sealing groove 132 and the sealing member 133 on the installation panel 13, the sealing performance of the connector can be effectively improved.

Through the limiting effect of the first retaining ring 1111 on the first power connection element 5, it can effectively prevent the plug from being inserted too deeply or disengaging from the jack, avoiding poor electrical connection or safety hazards caused thereby. Such a design can ensure a firm connection between the plug and the jack, and improve the safety and stability of the connector. The first jack 51 is provided with a power connection elastic piece 52, which can ensure a reliable electrical contact between the plug and the jack after the plug is inserted. This helps to reduce the contact failure or open circuit phenomenon caused by plugging and unplugging, and improves the reliability and stability of the connector.

[0035] The second power connection plug 112 includes a mating surface 1121. A plurality of mating jacks 1122 are evenly distributed on the mating surface 1121. The second power connection element 6 is arranged in the mating jacks 1122. At the port of the mating jacks 1122, a second retaining ring 1123 is provided, and the second retaining ring 1123 is used to limit the second power connection element 6.
