Dustproof cover for charging port of electronic device and charging base corresponding to dustproof cover

A dustproof cover inserted into a charging port of an electronic device to prevent dust entering into the charging port, the charging port comprising a pair of charging terminals, the dustproof cover comprising:

• a plug;
• a cover body fixed with one end of the plug;
• a plurality of metal connecting posts, a first end of each of the plurality of metal connecting posts extending into the plug;
• and
• a conductive part located between the plug and the cover body, and wherein a second end of each of the plurality of metal connecting posts is electrically connected to the conductive part;
• wherein 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;
• and
• a printed circuit board (PCB) located between the plug and the cover body, wherein the plug comprises a pair of positioning portions located at one end of the plug, a positioning slot is defined between the pair of the positioning portions, wherein the PCB is positioned in the positioning slot, the second end of each of the plurality of metal connection posts is inserted into the PCB, and is electrically connected to the PCB, and wherein the conductive part comprises a pair of conductive posts located between one of the positioning portions of the plug and the cover body and electrically connected to the PCB, and one end of each conductive post is exposed out of the cover body, wherein each positioning portion defines a positioning hole, each conductive post comprises a connecting portion, a positioning post, and a conductive contact, the positioning post and the conductive contact respectively extend from two sides of the connecting portion, and wherein the positioning post is inserted into the positioning hole of a corresponding positioning portion of the plug, and the connecting portion contacts the PCB and is electrically connected to the PCB, and wherein the conductive contact is exposed out of the cover body and fixed with the cover body, an extending direction of the positioning hole being parallel with the metal connecting posts.
