Abstract

The invention relates to an IC card waterproof structure comprising a housing which is provided with a card slot; the IC card seat is arranged in the shell and comprises a card seat opening corresponding to the card inserting opening; the circuit board is welded on the top surface of the IC card seat; the support comprises a bottom frame, an opening formed in the front side of the bottom frame and corresponding to the clamping seat opening, and a fence surrounding the left side, the right side and the rear side of the bottom frame, and the opening is located in the front side of the bottom frame; and one side of the surface frame is pressed against the inner side of the card inserting opening, and the other side of the surface frame is pressed against the card seat opening and the opening for sealing. The surface frame is integrally connected with the bracket; or the face frame and the support are arranged in a split mode. According to the IC card waterproof structure provided by the invention, water entering from the card slot is blocked by the surface frame and the bracket and does not flow to other places in a machine, so that a waterproof effect is achieved. The cost is low, and the occupied internal space of the shell is small.
