[0021] By setting the left connecting shell 1 and the right connecting shell 2, it can be more convenient to plug and install the terminal male end 3 and the terminal female end 4. At the same time, by setting a quick-release component and utilizing the sliding connection between the pin block 7 and the pin hole in the quick-release component, it can be more convenient to utilize the movable clamping block 8 provided on the pin block 7, so that it can be more convenient to install and plug the terminal male end 3 inserted on the left connecting shell 1 and the terminal female end 4 inserted on the right connecting shell 2. At the same time, the sealing component can also further improve the sealing effect of the connection between the terminal male end 3 and the terminal female end 4.
