## Abstract

A dustproof cover of the disclosure is inserted into a charging port of an electronic device to prevent dust entering into the charging port. The charging port includes a pair of charging terminals. The dustproof cover includes a plug, a cover body fixed with one end of the plug, a plurality of metal connecting posts, and a conductive part located between the plug and the cover body. A first end of each metal connecting post extends into the plug, and a second end of each metal connecting post is electrically connected to the conductive part. In use, the plug is inserted into the charging port, the plurality of metal connecting posts contact the charging terminals, the conductive part is electrically connected to the charging terminals, and the cover body covers the charging port. The present disclosure also discloses a charging base corresponding to the dustproof cover.

## Claims

### Claim 1
