5 and 8, the slide door 250 includes a protrusion 252 formed on one surface and a knob 251 formed on the other surface, and at least a part of which is inserted into the slot. The protrusion 252 is a portion protruding from one surface of the slide door 250 to be coupled to the coupling portions of the support frame 280 to be described later.

6 and 9, the support frame 280 may include a body 281, a support 284, and coupling parts 282 and 283. Body 281 has a slot 286, and support 284 is coupled to both sides of body 281 defining slot 286 across slot 286.

The body 281 of the support frame 280 includes a guide member 285 protruding from the end. The guide member 285 is formed to surround at least one side of the slide door 250. The slide door 250 is formed to be able to slide from the guide member 285 during the movement.

Couplings 282, 283 extend from both sides of support 284, respectively. The coupling parts 282 and 283 may be divided into a first coupling part 282 and a second coupling part 283. The first coupling part 282 is provided with a hook 287 so that the protrusion 252 of the slide door 250 can be coupled in a state in which the slide door 250 is closed. The second coupling part 283 includes a hook 288 to allow the protrusion 252 of the slide door 250 to be coupled with the slide door 250 being opened. The hook may protrude from one side of the coupling portion or may be recessed inwardly at one side.

The coupling parts 282 and 283 may be formed in the shape of a cantilever beam extending from one end fixed to the support part 284. At this time, the other end spaced apart from the fixed end becomes a free end. Here, the part in which the hooks 287 and 288 of the cantilever beam are formed is formed to be deformed toward the inside of the terminal.

A state in which the cantilever is not deformed and positioned in parallel with the body 281 is in a first state, and the protrusion 252 pushes the cantilever inwards as the slide door 250 moves so that the cantilever is deformed inwards. Becomes the second state. The cantilever accumulates elastic energy in the second state and then returns to the first state when the protrusion 252 is fitted to the hooks 287 and 288 to release the restraining force by the protrusion 252.

The slide door 250 has a knob 251. The knob 251 protrudes from one surface of the slide door 250 and is formed to be movable along the slot of the slot part 230. That is, the outer circumference of the knob 251 is formed to contact the inner circumferential surface defining the slot.

Due to the structure as described above, it is possible to minimize the thickness of the slide door 250 and the support frame 280. That is, the support frame 280 is provided with a guide member 285 for guiding the slide movement of the slide door 250 as well as a hook for engaging with the protrusion 252 in the closed and open state of the slide door 250 ( By providing coupling parts 282 and 283 having 287 and 288 formed therein, it is possible to minimize the combined thickness of the slide door 250 and the support frame 280.

As a result, a larger display area can be formed by minimizing the bezel of the terminal.

According to the present invention, a process of assembling the slot unit 230, the slide door 250, and the support frame 280 to the terminal body may be simplified.

The process is as follows. As shown in FIGS. 5 and 6, first, the slide door 250 is brought into close contact with the slot 230 so that the slide door 250 may move along the slot. At this time, the knob 251 of the slide door 250 should be inserted into the slot. Then, the support frame 280 is coupled to the slot 230 so as to cover the slide door 250. This coupling may be achieved by fitting the support frame 280 to the protrusion projecting from the slot portion 230, or by heat-sealing the support frame 280 to the slot portion 230.

10A and 10B are operational state diagrams of a slide door 250 according to embodiments of the present invention. FIG. 10A illustrates a closed state in which the slide door 250 covers the socket 240 and an open state in which the slide door 250 exposes the socket 240.

As shown in FIG. 10A, the protrusion 252 of the slide door 250 is inserted into and coupled to the hook 287 of the first coupling part 282 in the closed state. When the user pulls or pushes the knob 251, the protrusion 252 of the slide door 250 is pushed out of the hook and pushes the hooked portion of the first coupling part 282 to contact the protrusion 252. A portion of the first coupling portion 282 is retracted.

When the slide door 250 moves and the second coupling part 283 and the protrusion 252 come into contact with each other, the second coupling part 283 retreats. When the protrusion 252 is moved to a portion where the hook 288 is formed while moving to a certain distance, the second coupling portion 283 is parallel to the body 281 by the restoring force, as shown in FIG. 10B. The protrusion 252 is coupled to the hook of the coupling portion 283.

The hooks 287 and 288 and the protrusion 252 remain in engagement with each other unless a predetermined force is applied in the closed or open state.

In the open state, an external device is inserted into the socket 240 to electrically connect the socket 240 and the external device.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
