BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal having an auxiliary housing and a locking device thereof, and more particularly to a locking device of a portable terminal having a detachable auxiliary housing constituting an auxiliary housing detachable by a slot provided in the terminal.

A typical wireless terminal refers to a portable device that allows a user to carry out wireless communication, such as voice, video communication, or data transmission, with a counterpart. Such a wireless terminal refers to a portable device that provides wireless communication service to a user while performing wireless communication with a base station. Current wireless terminals can be classified into various types according to their function, appearance or wearing position.                         

Wireless terminals can be categorized as bar-type, flip-type, or folder-type wireless terminals depending on their appearance and, depending on their function, can be used for voice communication, video communication or the Internet. It may be classified as a communication or the like, and may be classified as a wrist-type or neck wearable-type wireless terminal according to a body wearing position.

Among the various types of wireless terminals, the structure of the wireless terminals classified according to appearance is as follows. The bar-type wireless terminal is a structure in which a data transmitting and receiving device, a data input / output device, and the like are mounted in a bar-type housing. The flip-type wireless terminal consists of a flip which is opened and closed by a hinge device to the bar-type wireless terminal. A typical flip protects a number of keys arranged in a bar-shaped housing and acts as a negative reflector. In addition, the folder-type terminal is composed of a main body, a hinge device for rotatably connecting the folder, the main body and the folder. The data input / output device and the data transmission / reception device are mounted in place of the main body and the folder.
