The configuration of the present invention is more useful when the side surface of the case has a rounded curved surface portion 107 as shown in Fig. In order to make the thickness of the terminal body slim but to form a curved surface on the side thereof, it is preferable that the mounting position of the connection port 220 is set to a certain distance inward from the outer surface of the case in consideration of the size of the connection port 220 . In this case, the connection port 220 may be far away from the opening of the case, and the user may inconvenience the connection of the connector of the external device to the connection port 220. The present invention can draw out the connection port 220 positioned at a certain distance from the opening portion to the outside, thereby solving the inconvenience described above.

The operation of closing the cap 230 is performed in the reverse order of the above-described operation. That is, when the cap body 231 is rotated in the counterclockwise direction, the slider 241 is received in its original position while the link member 242 is rotated and linearly moved.

6A and 6B are cross-sectional views of a mobile terminal taken along the line VI-VI of FIG. 6A and 6B show a state in which the opening is blocked by the cap and a state in which the cap is rotated and the opening is opened, respectively.

6A and 6B, a locking portion 260 is provided between the cap 230 and the slider 241 to fix the position of the slider 241 in the extended state of the connection port 220.

The locking portion 260 may include a locking protrusion 261 formed in the cap 230 and a locking groove 262 formed in the slider 241.

The locking protrusion 261 may be formed at the end of the cap body 241 and the locking groove 262 may be formed at the back of the slider 241. In the opening operation of the cap 230, the locking protrusion 261 is caught and fixed in the locking groove 262. For this purpose, the locking protrusion 261 and the locking groove 262 are formed at positions corresponding to each other when the slider 241 is completely drawn out.

According to the above-described configuration, it is possible to prevent the connection port 220 from being pushed by the connector and returning to the receiving portion in the process of connecting the connector of the external device to the connection port 220.

When the cap body 231 is rotated in the closing direction with the locking protrusion 261 held in the locking groove 262, the locking protrusion 261 is disengaged from the locking groove 262 and thus the locking of the slider 241 So that the slider 241 can be returned.
