With the development of technology, many small sized terminal devices have been introduced to enable various portable electronic devices to be integrated and miniaturized to be easily carried by individuals. For example, clamshell cell phone, bar cell phone, slide cell phone, MP3 player, CD player, portable multimedia player (PMP), personal digital assistants (palm), palm, portable small TV, portable game machine These include mobile terminals such as laptops, electronic dictionaries, digital cameras, navigation, and GPS receivers.

Most of these terminal devices are expensive and appearance design is important, and terminal users tend to pay considerable attention to damage, such as scratches, scratches, peeling, etc., in the appearance design. In addition, these terminal devices use high-tech precision parts inside, so the robustness of the outer housing is important.

In general, such a terminal uses a housing made of a weak material in order to reduce the size and light weight of the terminal in terms of design and portability. Most of these housings are made of a thin synthetic resin material, which is weak in external impact and easily scratched.

Complementing the shortcomings of the terminal housing, and by using a separate, solid case on the outside of the terminal housing to properly decorate the appearance according to the user's taste, protects the terminal and the housing of the outside, and induces a unique personality and aesthetic The method has been mainly used. Referring to the drawings to describe such a prior art is as follows.

Since the case uses synthetic resin made of an elastic material, the locking jaws 116 and 126 prevent the detachment while pressing the display unit 12 and the keypad unit 16 inward.

Such a conventional case has an advantage that the coupling is easy and firmly fixed. However, the locking jaw should be formed to fix the case, and the locking jaw may cause scratches or scratches by scratching the surface of the terminal when the terminal is coupled with the case.

In addition, there is a minute gap between the main body and the surface of the terminal, when the long-term use, the foreign matter such as dust penetrates into this gap and accumulates, which is not good in appearance, and also scratches the surface of the terminal due to friction.

In addition, if the locking step is a little broken or deformed, the coupling state may be loose or the coupling itself may be impossible. On the other hand, there is a problem that the user may injure the skin due to the sharp shape of the locking jaw.

Therefore, there is a need for a terminal case that can be easily combined but prevents the penetration of foreign materials without damaging the terminal.
