[0005] The male sealing gasket is arranged between the male base and the male terminal.

[0006] The sealing ring is arranged between the male positioning part and the female positioning part.

[0007] The female sealing gasket is arranged on the female positioning part.

[0008] Compared with the prior art, the utility model has the advantages of small size and convenient installation. The turning needle is used as the current conductor contact piece, the current carrying capacity can satisfy more than 100A, which is much higher than other connectors on the market, and the spring leaf is used in the female terminal, so that the plug-in and plug-out life can be satisfied for more than 3000 times. The two metal guide posts are fixed on the male terminal positioning piece by using the gold embedding process, the metal guide post is first inserted into the positioning hole of the female terminal positioning piece when plugging, and the male terminal is contacted with the female terminal after the guiding effect is played. It is convenient to plug and pull, and the product damage is reduced. The boss is arranged, the boss is matched with the groove on the shell to be connected with the female terminal positioning piece, and the guiding and positioning effect is played. The wear between the terminals is greatly reduced, and the service life is improved. The male terminal comprises a plurality of turning needles, and the female terminal comprises a plurality of turning holes, so that the charging and discharging integrated demand can be satisfied.
