The present invention relates to a terminal cover opening and closing device of a mobile terminal, and more particularly, to a terminal cover opening and closing device of a mobile terminal, which constitutes a guide member integrally provided with an elastic member in the terminal cover of the mobile terminal.

In general, the term “portable terminal” refers to a device that a user can carry and wirelessly communicate with a counterpart. Such portable terminals are classified into various types in appearance. For example, portable terminals are classified into bar-type, flip-type, or folder-type terminals according to their appearance. The bar-type terminal means that the single housing is configured as a bar-type, the flip-type terminal means that the bar-type housing and the flip is rotatably coupled by the hinge device, the folder-type terminal is a single It is meant that the folder in the bar-shaped housing is rotatably connected by a hinge device and configured in a folding manner.

In addition, the portable terminal may be classified into a neck wearable type or a wrist wear type according to a body wearing position. A necklace-type terminal means a portable method of wearing the terminal around the neck using a string, and a wrist-type terminal means a portable method of wearing the terminal on the wrist.

In addition, the portable terminal may be classified into a rotation-type or sliding-type wireless terminal according to an opening and closing method. The rotatable terminal means that the two housings are rotatably connected and opened in a facing state while facing each other, and the sliding-type terminal means that the two housings are opened and closed in a facing state with longitudinal movements. The variously classified portable terminals listed above will be readily understood by those of ordinary skill in the art.

On the other hand, such portable terminals are provided with terminals for connection with other information devices such as personal computers or peripheral devices. For example, an interface connector for connecting a USB port of a personal computer, a travel charger, and an earphone jack for connecting to an earphone. The terminals are provided on the bottom surface or the side of the terminal and are protected by a rubber cover.

As shown in FIG. 1, a portion capable of holding the earphone jack 5 is provided on the upper side or side surface of the portable terminal 1. When the earphone jack 5 is not plugged in, a folding type terminal cover 2 is installed in order to prevent intrusion of foreign matter into the main body 1.

2 and 3, the conventional terminal cover 2 is made of a urethane rubber material, has a stopper (2a) to be inserted into the mounting hole (3) of the main body 1 so as not to be separated and penetrates the main body (1) The hole 4 was formed, it had the cylindrical part 2b inserted in the said through-hole 4, and sealed inside, and had the structure 2c which can open and close to the upper part.

In addition, an opening 6b is formed in the jack 6a of the main board 6 so as to be fastened to the earphone jack.

Moreover, it was the structure which has the hinge part 2d with tension so that the rotational movement of the said terminal cover 2 may be possible.

The terminal cover 2 is opened and closed around the hinge portion 2d. When the earphone is not used, the cover 2 is inserted into the through hole 4 of the main body 1, and the earphone is In use, the earphone jack is coupled to the jack 6a of the main board 6, and the terminal cover 2 is open.

However, the conventional folding type terminal cover is made of a louver material, and due to the heterogeneity caused by the difference between the injection molding and the material, the cover of the louver has a limitation in making the texture of the surrounding injection, and most of the cover of the louver is Since the structure is opened and closed by the nail by external force, the operation is difficult, and the cover is damaged or broken due to the opening and closing by the user.

In addition, there is a disadvantage that the cover and the through hole are not precisely manufactured due to tolerances due to the injection problem, so that the cover is lifted from the through hole of the main body.

In addition, the terminal cover of the portable wireless terminal of Patent Application No. 2003-58773 already filed is a sliding type of opening and closing the cover in a sliding manner.

The sliding type terminal cover is composed of a cover base to which the elastic pieces are separately assembled, a cover housing and two doors coupled to the cover base, and thus, when the terminal cover is slid, the cover and the door overlap each other and close. In this case, the door can be closed by the elastic piece. When repeatedly operated several times, the elastic force of the elastic piece is lowered, and the assembly process is difficult because the elastic piece must be assembled on the back of the door. An increase in the number of parts has a disadvantage in that the manufacturing cost of the terminal cover increases.

In order to solve the above problems, it is an object of the present invention to provide a terminal cover opening and closing device of a mobile terminal to facilitate opening and closing of the terminal cover in the mobile terminal.

It is still another object of the present invention to provide a guide member having an elastic member integrally formed in a terminal cover of a mobile terminal, thereby improving the operation of the elastic member and reducing the number of assembly parts, thereby improving the assembly process of the terminal cover. The present invention provides a terminal cover opening and closing device for a mobile terminal.
