The receiving cavity 31 is surrounded by four side walls 310 and a bottom wall 312. 31 is used to house a battery 90 of a mobile phone. A receiving slot 32 is defined in the housing 30. The receiving slot 32 is located on one side of the receiving cavity 31 and communicates with the receiving cavity 31 through a side wall 310. The receiving slot 32 is for receiving the SIM card 10 and the stop pad 50. The receiving slot 32 defines a positioning cavity 33 adjacent to one side of the receiving cavity 31 for positioning the stop pad 50.

The stop pad 50 is made of a flexible material, such as rubber, soft plastic, etc., and has the function of buffering and stopping. The stop pad 50 includes a main body 51 , a positioning portion 52 , and two buffer portions 53 . The main body 51 has a rectangular shape, and the positioning portion 52 protrudes laterally from one end of the main body 51, and the positioning portion 52 and the main body 51 form an "L"-shaped structure. The positioning portion 52 can be received in the positioning cavity 33 to hold the main body 51 in the receiving groove 32. The two buffer portions 53 are respectively disposed at two ends of the side edges of the main body 51 and the positioning portion 52. When the main body 51 is locked in the receiving groove 32, the two buffer portions 53 are abutted against the side wall 310.
