  • Patent number: 10686480
    Abstract: A mobile terminal further comprises: a case having an opening formed therethrough so as to communicate with the inside thereof; and a card tray inserted in the opening, wherein the card tray further comprises a cover part for covering the opening; a support part positioned inside the opening and comprising a seating part on which a card is stably placed; and a flexible part connecting the support part and the cover part and fitted/coupled to the circumference of the opening. The mobile terminal wherein the relative position of the cover part to the support part changes with morphological changing of the flexible part allows the positions of the cover part and the support part in the card tray to be flexibly variable. Therefore, even when positions of the opening and a card socket are mismatched, a card can be mounted in the mobile terminal, thus reducing an initial detective rate and an operationally detective rate.

  • Patent number: 10491257
    Abstract: The mobile terminal is disclosed. The mobile terminal of the present invention may include a body having a body hole, a display unit, a waterproof unit, and a second guide unit. A part of the waterproof unit is movable in the body hole, and the waterproof unit may open and close the body hole. When the waterproof unit shields the body hole, liquid inflow from the outside to the inside may be suppressed through the body hole. The second guide part may guide a part of the waterproof unit to move in the direction of opening the body hole in the body hole. The waterproof unit may include a waterproof unit body moving inside the body hole, a guide connection part extending from the waterproof unit body, and a guide bending part extending from the guide connection part and curved. The guide bending part is guided away from the waterproof unit body, so that warpage of the waterproof unit may be prevented.
