Moreover, the box can be made into a waterproof structure, which can prevent the danger of leakage when connecting high voltage.

[0043] Reliability: The sliding gap of the slider 5 and the deviation of the installation position of the plug fixing seat 1 will cause the alignment of the plug 3 and the socket 8 to be skewed, and the contact conductive metal sheet of the plug 3 is at risk of being hit and bent. In view of this problem, the degree of freedom of the plug 3 in the plug fixing seat 1 is specially designed, that is, the four degrees of freedom of the front, rear, up and down of the plug 3 are limited, and a certain margin of freedom in the left and right directions is reserved. When the plug 3 and the socket 8 are plugged together, the positioning head 81 first contacts the positioning groove 31 of the socket 8. The edges of the positioning head 81 and the positioning groove 31 have a guiding C surface. When misalignment occurs, the guiding C surface can slide into the positioning groove 31. Through the setting of the C surface, it is possible to achieve a small size at one end of the positioning head 81 facing the positioning groove 31 and a large size at one end of the positioning groove 31 facing the positioning head 81. The positioning groove 31 can fine-tune the position of the socket 8 according to the position of the plug 3 (position adaptation), thereby avoiding the risk of the pins of the plug 3 being hit and bent after misalignment, and improving the reliability of automatic connection.
