Abstract
Disclosed is a battery pack locking device for a portable wireless terminal which is configured to utilize a locking method in which support protrusions formed at one end of a battery pack are engaged with support grooves formed at the terminal body of the portable wireless terminal, and the battery pack is then brought into close contact with the seat surface of the terminal body, while using a button member adapted to perform a depressing operation, thereby achieving an easy separation of the battery pack from the portable wireless terminal. In accordance with the configuration, it is possible to prevent the fingernail of the user from being damaged during the attachment or detachment procedure of the battery pack. In particular, it is unnecessary to provide an additional space for allowing a horizontal movement of the locking device. Accordingly, there is an increased flexibility in the design of the terminal appearance.
