It will be appreciated that by providing the first elastic member 22, the sealing sleeve 21 can selectively open the receiving cavity 24, for example, under the action of the second charging connector 200 which is butted thereto, so that the liquid metal can flow out of the receiving cavity 24 and directly contact the second charging connector 200, which can ensure the charging reliability and safety of the vehicle, and can further reduce the operating temperature of the first charging connector 100 and the second charging connector 200.
It should be noted that the first elastic element 22 is arranged to ensure the reliability of the sealing plug 23 sealing the receiving cavity 24 on the one hand, and to facilitate the opening of the receiving cavity 24 on the other hand.
Alternatively, as shown in fig. 1 and 4, a base 25 is provided inside the sealing sleeve 21, for example, there may be a single piece between the sealing sleeve 21 and the base 25. The base 25 is provided with a weep hole 26 and the first resilient member 22 is resiliently disposed between the base 25 and the sealing plug 23, the sealing plug 23 being axially movable relative to the base 25. The axial displacement reliability of the sealing plug 23 can be guaranteed by the arrangement of the base 25, and under the action of the first elastic part 22 compressed in a matching mode, the effect of limiting the displacement of the sealing plug 23 is achieved, so that the opening degree of the accommodating cavity 24 is guaranteed to be appropriate, and the working reliability of the first charging connecting part 100 can be guaranteed.
