The tops of the integrated circuit chips 2 and the connecting frames 3 are fixedly connected with a protective cover plate 4. The inner wall of the connecting frame 3 is provided with a cavity. The inner wall of the connecting frame 3 located in the cavity is fixedly connected to an elastic metal sheet 6. The end of the elastic metal sheet 6 is fixedly connected to a slider 7. The slider 7 is slidably provided on the inner wall of the connecting frame 3 located in the cavity. The end of the slider 7 facing away from the elastic metal sheet 6 is fixedly connected to a limiting card plate 8. The inner wall of the IC card 1 is provided with a card slot. The limiting card plate 8 is clamped on the inner wall of the IC card 1 located in the card slot. The inner wall of the connecting frame 3 is fixedly connected to a sealing rubber pad 5.
