Waterproof foam 600 is arranged between the battery cover 500 and the annular edge portion 322, and the sensing assembly 320 is in sealing fit with the battery cover 500 through the waterproof foam 600. The waterproof foam 600 can prevent liquid such as water from entering the interior of the mobile terminal through the gap between the battery cover 500 and the sensing assembly 320, thereby preventing devices such as the main board 100 of the mobile terminal from being damaged.
Specifically, the waterproof foam 600 may have a width of 1.2mm and a thickness of 0.8 mm.
In order to improve the waterproof effect of the waterproof foam 600, the waterproof foam 600 may be configured as an annular foam which is disposed around the axis of the annular edge portion 322.
