The cover plate 21 is made of elastic materials such as rubber, the cover plate 21 can be sealed with the opening hole 13, the hole plug 2 embeds the first contact 23 and the second contact 24 into the cover plate 21 in an injection molding mode, and gaps are prevented from being generated between the first contact 23 and the second contact 24 and the cover plate 21.

In this embodiment, as shown in fig. 4, a magnet 25 is further embedded in the cover plate 21 of the plug 2 for interfacing with a magnetic attraction head (not shown, the same applies below).

As shown in fig. 2, a connector 3 is accommodated in the housing 1 and exposed to the opening 13, the connector 3 includes at least a pair of terminals 31, in this embodiment, the connector 3 is a USB connector 3, specifically, USB Type-C, and as shown in fig. 5, which is an enlarged view of the connector 3 in this embodiment, the pair of terminals 31 can be a positive power terminal and a negative power terminal or a signal terminal and a ground terminal or a pair of differential signal terminals.

When the cover 21 covers the opening 13, the first contact 23 and the second contact 24 are electrically connected to one of the pair of terminals 31, preferably, the first contact 23 is electrically connected to the positive power terminal, and the second contact 24 is electrically connected to the negative power terminal (usually, a ground terminal is used as the negative power terminal).

As shown in fig. 6, when the PIN definition of the connector 3 of the present embodiment is shown, and the pair of terminals 31 are a positive power supply terminal and a negative power supply terminal (a ground terminal serves as the negative power supply terminal), the first contact 23 contacts the positive power supply terminal, and the second contact 24 electrically contacts the negative power supply terminal.

As shown in fig. 7 and 8, when the hand-held terminal 100 is placed on the mating charging dock 4, the first contact 23 and the second contact 24 are in contact with the charging terminal 41 on the charging dock 4 to charge the hand-held terminal 100.
