The USB connector comprises a printed circuit board, a USB connecting terminal and a card connecting terminal, the printed circuit board comprises an interface end spliced with a USB slot, the USB connecting terminal is arranged on the first surface of the interface end, the card connecting terminal is arranged on the second surface of the interface end, and a fixing mechanism used for fixing a smart card is arranged on the second surface. In the application, the smart card is arranged on the connecting end, for enabling the smart card to be away from a high heating region of the printed circuit board, to avoid influence of heat radiated in a working process to the smart card, as well as avoiding the problem that the smart card is burnt by over heat to reduce unnecessary loss. In addition, in the application, the card connecting terminal and the smart card are arranged on the interface end, to further reduce a holding space reserved to the smart card in the high heating region of the USB connector, thereby being helpful to lightness and thinness of products. |
