Since the rear card support hole 12 is exposed outside the mobile terminal 100, dust or liquid may enter the mobile terminal 100 through the rear card support hole 12, the present disclosure seals the rear card support hole 12 by sleeving the sealing ring on the card support 50 to seal the rear card support hole 12, and the dust or liquid is prevented from entering the mobile terminal 100 from the rear card support hole 12.

Illustratively, the card holder 50 includes a main body portion for placing one or more electronic cards and a rear cover portion disposed at the rear end of the main body portion and matching with the shape of the rear card holder hole 12, for example, the rear cover portion may be a flat rectangle to supplement the missing portion of the rear housing 10 due to the opening of the rear card holder hole 12. The main body part is provided with a groove part for fixing the sealing ring 60, wherein the section of the sealing ring 60 in the circumferential direction is larger than the depth of the groove part, and the sealing ring 60 protrudes outwards when being fixed in the groove part so as to ensure the interference fit with the inner wall of the rear clamping support hole 12. In addition, the possibility of falling off caused by interference and friction with the rear card support hole 12 in the insertion and extraction process of the card support 50 is also prevented, and the sealing reliability is ensured.

In summary, as shown in fig. 8 and 9, in the mobile terminal 100 according to the embodiment of the disclosure, when the sealing member 40 is assembled between the front case 20 and the rear case 10, the rib 42 of the first surface 411 of the sealing body 41 is matched with the groove 23 of the front case 20, and the second surface 412 of the sealing body 41 is adhered to the rear case 10 by the waterproof back adhesive, so as to seal the gap between the front case 20 and the rear case 10, and prevent dust or liquid from the gap from entering the interior of the mobile terminal 100 through the front card pin hole 21 and the front card receiving hole 22 of the front case 20. The sealing plug 43 on the second surface 412 of the sealing body 41 is in interference fit with the rear latch hole 11 of the rear housing 10, and seals the rear latch hole 11 to prevent dust or liquid from entering through the rear latch hole 11. In addition, the sealing plug 43 is provided with a second through hole, when the clamping needle 200 (shown in fig. 6) is inserted into the sealing plug 43, the first through hole is opened, when the clamping needle 200 is pulled out from the sealing plug 43, the first through hole is closed, the second through hole is opened or closed through the deformation of the sealing plug 43, and the second through hole which is formed by the sealing plug is sealed while the smooth insertion and pulling out of the clamping needle 200 are not influenced. Furthermore, the sealing ring 60 on the card holder 50 is in interference fit with the rear card holder hole 12, so that the rear card holder hole 12 is sealed, and dust or liquid is prevented from entering through the rear card holder hole 12. Therefore, the gap between the front shell 20 and the rear shell 10, the front clamping pin hole 21 and the rear clamping pin hole 11, and the front clamping support hole 22 and the rear clamping support hole 12 can be sealed in all directions through the integrated sealing element 40 and the sealing ring 60 on the clamping support 50, the sealing effect is greatly improved, the material cost is greatly reduced, and the assembly convenience is greatly improved.
