The present invention relates to a battery for a portable terminal and a portable terminal having the same, and more particularly, to a portable terminal battery and a portable terminal having the same for slimming the portable terminal.

In general, portable terminals such as mobile phones, personal digital assistants (PDPs), and portable multimedia players (PMPs) are manufactured to satisfy miniaturization, light weight, slimness, and reliability in order to satisfy various needs of users such as ease of use and portability. . In addition, a battery that is mounted on a portable terminal to supply power so that the portable terminal can be used while being portable or mobile has also been miniaturized, lightened, and large in capacity.

The conventional portable terminal has a battery mounting structure of a vertical separation type, the terminal body is provided with a locking device for locking the battery, the battery is formed with a locking groove that is supported by the locker (locker) of the locking device.

A compression coil spring is installed between the locker and the terminal body to return the locker to its original position when the locker is moved by an external force. The compression coil spring has a predetermined number of turns to maintain elasticity for restoring the rocker and supports the center of the rocker.

In the conventional portable terminal, when the battery is pushed into the terminal body, the locking jaw of the locker is coupled to the locking groove of the battery so that the battery is mounted on the terminal, and then the elasticity of the compression coil spring that supports the locker and the terminal body The binding force of the battery is maintained.

When the terminal body and the battery are separated, an external force is applied to the handle part of the locker provided in the terminal body to release the coupling force between the locking jaw of the locker and the locking groove of the battery. When the battery is disconnected, the locker of the terminal body is restored to its original position by the elasticity of the compression coil spring.

In the conventional portable terminal as described above, since the locker for fastening the battery is installed in the terminal body, sufficient space for the locker to move and the depth of the inside of the terminal body due to the size of the compression coil spring that provides the restoring force to the locker are provided. It requires a lot of space in the direction, making it difficult to miniaturize and slim the portable terminal.

In addition, since the compression coil spring supports the center portion of the rocker, if an external force for moving the rocker is not applied to the center portion of the rocker, the compression coil spring may swing in a vertical direction in the direction in which the rocker moves, and thus may not be restored to its original position.
