In addition, the terminals 205 are installed on the front and rear surfaces of the battery 201 so as to be exposed. The terminal provided on one side of the battery 201 has a configuration in contact with the connection terminal protruding on the rear surface of the main body, the terminal provided on the other side has a configuration in contact with the connection terminal of the charger during charging.

However, as described above, the battery fixing device has to be pushed together with guide ribs formed on both sides of the main body so that both side guide ribs of the battery are caught by each other. There was this.

SUMMARY OF THE INVENTION An object of the present invention is to provide a battery fixing device for a portable terminal, which enables to easily mount and detach a battery detachable from a main body of the portable terminal.

Another object of the present invention is to provide a battery fixing device for a portable terminal, which is easily separated by separating a battery that is not easily separated from the main body case of the portable terminal by a locker.

In order to achieve the above object, the present invention provides a battery that is mounted on the main body of the portable terminal, and has a locking groove at the lower side and a fixing groove at the top and bottom thereof, and forms a battery seating groove at the body, and at the center of the lower side of the seating groove. Protruding support ribs are formed, and the upper portion is provided with a rocker having a fixed protrusion projecting upwardly on the front and the bottom so as to slide forward and backward on the main body, and the rocker is moved to the front and rear by installing a spring on the rib formed on the rear side. When the battery is installed, the locking groove is inserted into the support rib and supported, and the front groove and the lower groove formed in the battery are fitted into and fixed to the fixing protrusions formed on the front and bottom.
