ABSTRACT:
An improved connector of a card reader, the card reader includes a circuit board in a housing as its principal unit; the circuit board has a USB connecting port to make circuit connection with a set of electric equipment, and is provided at least with one aforesaid connector for insertion of a memory card. Wherein: the main body of the connector is integrally made by injection molding purely of plastic, and a grounding electric circuit of the connector is connected to a metallic housing of a USB connecting port to form circuit continuation of the metallic housing of the USB connecting port and the electric equipment, and to effectively prevent static-electricity damage. Because the main body of the connector is made by injection molding purely of plastic, this can largely lower the cost of production of the connector.
