Accordingly, the sizes of the first to third accommodating parts 421, 422, and 423 are formed corresponding to the shapes of the respective external cards.

There is no limitation on the size of each of the storage units, and the shapes of the plurality of storage units may all be the same. The external cards are stored in the first to third accommodating parts 421, 422, and 423, respectively.

The socket 400 includes a cover part 430 formed to cover at least a portion of the body part 420. The cover part 430 is coupled to overlap the body part 420. In addition, the cover part 430 may have an opening 431 formed to expose at least a portion of the outer card so that the outer card and the terminal body may be electrically connected to each other.

That is, the cover part 430 is formed such that a plurality of external cards accommodated in the first to third accommodating parts 421, 422, and 423 are not separated from the socket 400. That is, the one cover part 430 overlaps at least a part of each of the first to third accommodating parts 421, 422, and 423 so that all of the plurality of external cards may be fixed at one time.

Therefore, since the outer card is fixed by the cover part 430, even if the socket 400 is withdrawn from the terminal body, the outer card is not separated from the socket 400, so that the outer card is It can prevent the problem of being lost.

The cover part 430 may be formed to be opened from the body part 430 so that the first to third accommodating parts 421, 422, and 423 are entirely exposed.

For example, the cover part 430 may be rotatably coupled to one side of the body part 430. That is, the cover part 430 may have a hinge part formed at one side of the body part 430 to be rotatably coupled to the hinge part. A guide part 423 may be formed on the other side of the body part 430, and a guide shaft 432 may be installed to control the degree of rotation of the cover part 430. One end of the guide shaft 432 is connected to the guide part 423 and the other end is connected to the cover part 430.

Accordingly, the cover part 430 may move with respect to the body part 420 to implement an open state in which the first to third accommodating parts 421, 422, and 423 are exposed. In the open state, the external cards may be stored in the first to third accommodating parts 421, 422, and 423, or separated and replaced.

Therefore, the user can accommodate a plurality of external cards of different sizes in the terminal body and replace the same. In addition, since various types of external cards are accommodated at one time, the number of grooves formed to insert the external cards into the external terminal of the terminal can be reduced, thereby improving the design luxury of the external terminal.

In addition, a plurality of external cards accommodated in the accommodating part may be fixed by the cover part to prevent the external cards from being lost outside the main body of the terminal.

The external card 423 (see FIG. 5) containing the memory includes a main body and a connector formed on one surface of the main body to provide or receive information. The external card is accommodated in the first to third housing parts 421, 422, and 423 such that the connector faces the cover part 430, and the connector is electrically connected to the terminal body to transmit and receive information. .

The connector overlaps the opening 431 of the cover 430 and is exposed to the outside of the socket 400. The connector of the outer card 423 (see FIG. 5) is prevented from being separated from the socket 400 of the outer card 423 (see FIG. 5) by the cover part 430 having the opening 431. May be exposed and electrically connected to the terminal body.

A connection part 310 (see FIG. 3) connecting the main circuit board 282 and the connector is formed through the opening 431 to connect the external card to the terminal body to transmit and receive information. Hereinafter, a connection structure between the connection unit 310 and the memory 423 (see FIG. 5) will be described.

5 is a cross-sectional view illustrating a connection structure between the socket and the circuit board of FIG. 3.

Referring to FIGS. 3, 4A, and 6, the outer card 423 is mounted in the socket 400, and the cover part 430 overlaps the body part 420 to be in a closed state. Although not shown in the drawing, at least a part of the main body of the outer card 423 overlaps with the cover part 430 and is fixed so as not to be separated from the receiving part.

The first connection part 311 is formed on the main circuit board 282. The first connector 311 may include a first member electrically connected to the main circuit board 282 and a second member bent from the first member to be electrically connected to the exterior card 423. The first and second members may overlap and elastically connect. The second member includes a protrusion protruding toward the outer card 423 so as to partially contact the connector of the outer card 423. That is, the first connection portion 311 may be formed of a C-clip (clip).

Since the connection part 311 includes elasticity, when the socket 400 is inserted into the inside of the terminal body, the connection part 311 passes through the cover part 310 that is relatively thicker than the outer card 423 and the outer card ( 423) can be in close contact.

The socket 400 covered by the cover part 430 so as not to be detached from the outer card 423 is inserted into the main body of the terminal while moving on the main circuit board 282 on which the connection part 311 is formed. do.

Referring to FIG. 5, an inner circumferential surface on which the opening of the cover part 430 is formed may be formed in a curved surface to be concave curved surface.

Therefore, when the socket 400 is inserted into the terminal body, the connector 310 is guided to move to the connector of the outer card 423 accommodated in the socket 400. Accordingly, the connection part 310 including the elasticity may stably contact the connector of the outer card 423, and may reduce the impact applied to the outer card 423 by elasticity.

In addition, the connection part 311 is formed of a C-clip (clip), since the external card 423 and the main circuit board 282 is connected, there is no need for a separate connection terminal or flexible printed circuit board. In addition, since the plurality of external cards are electrically connected to the main circuit board 282 separately, the internal structure can be simplified.

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.
