In some embodiments, the distance L1 between the lens 261 and the first side wall 222 is 0.4 mm.

In the actual development process, the lens 261 itself has tolerances. Since the camera 26 is fixed by the housing 25, there are tolerances between the housing 25 and the camera 26, as well as the tolerance of the display screen, so that the lens 261 and the first side wall 222 are mutually The longer the tolerance chain is to form a dimensional relationship, the longer the tolerance chain is, the larger the sum of tolerances is, and a sufficient space needs to be reserved between the lens 261 and the first side wall 222 . The additional spacing space not only occupies the display area of the display screen 22, but also increases the diameter of the first through hole 221, which reduces the security of the display screen, and also increases the black border at the position of the first through hole 221, which affects the display screen 22. The appearance of the display surface is not easy for the user to use.

For this reason, in the embodiment of the present application, the distance L1 between the lens 261 and the first side wall 222 is controlled to be 0.4 mm, and the distance between the lens 261 and the first side wall 222 will not be collided with, and the distance between the first through hole 221 is reduced. diameter, increasing the display area of the display screen 22.

When installing the camera 26 , the lens 261 of the camera 26 is placed in the first through hole 221 , and the connecting body 262 of the camera 26 is placed in the second through hole 259 and fixed by the second side wall 258 and the connecting body 262 connected to position the camera 26 on the housing 25 . It should be noted that, a positioning structure may also be provided at the position of the second side wall 258 to further position the connecting body 262 .

It should be noted that the method of reducing the diameter of the first through hole 221 while maintaining a safe distance between the lens 261 and the first side wall 222 is not limited to setting the distance L1 between the lens 261 and the first side wall 222 at 0.4mm.

Please refer to FIG. 5 , which is another partial cross-sectional view of the mobile terminal in the direction A-A of FIG. 2 . The difference between the mobile terminal shown in FIG. 5 and the mobile terminal shown in FIG. 3 is that the camera 26 of the mobile terminal in FIG. 5 is positioned through the display screen 22 , so that the tolerance of the housing 25 and the camera 26 can be reduced. Further, the tolerance chain between the camera 26 and the first side portion 222 of the first through hole 221 of the display screen 22 can be reduced, and the tolerance size between the camera 26 and the first side wall 222 can be reduced. Under the condition that the size of the lens 261 of the camera 26 remains unchanged, the size of the first through hole 221 can be reduced, the display area of the display screen 22 can be increased, and the width of the black border at the position of the first through hole 221 can be reduced.
