Abstract
A waterproof structure installed in card machine includes a rigid support and a flexible support. The rigid support, formed of plastics, includes a frame that internally extends into two transversal bars. The transversal bars oppositely connect a receptacle frame located between the transversal bars so that a magnetic head of the card machine can be tightly arranged in the receptacle frame. The flexible support, formed of rubber material, includes a central region where a fixation slot is defined. The fixation slot matches with the receptacle frame to fixedly fasten the magnetic head. An opening is defined in the fixation slot, whereby the magnetic head can connect into a flexible circuit carrier. On upper and lower sides of the fixation slot, a clamping member composed of semi-ringed flanges is arranged around the fixation slot to tightly clamp the transversal bars of the rigid support.
