The PCB 7 is installed between the cover 5 and the lower cover 6 and is equipped with various parts.

In addition, the pad exposure hole 5a of the upper cover 5 is inserted so that keypads 8 for inputting information are exposed to the outside, and the side of the lower cover 6 of the main body 1 has a tone during a call. Side keys 9 for adjusting the tone are provided.

FIG. 2 is a cross-sectional view showing the inner structure in which the side keys are installed in detail. As shown in the drawing, one side of the FPC 11 is fixed to the lower side of the PCB 7 by soldering. , The other side of the F fish 11 is fixed to the support 12 protruding from the lower cover 6 to a predetermined height. The dome switch 13 is attached to the F-fish 11 fixed to the support part 12 by the adhesive sheet, and the side key 9 is inserted in the key engagement hole 9b of the lower cover 6, The outer side of the dome switch 13 is located inside the side key 9 so as to operate the dome switch 13 by operating the side key 9.

In the conventional portable terminal configured as described above, when the user transmits and receives, the user opens the folder 2 and presses the keypad 8 with his or her finger to transmit and receive.

If the user wants to adjust the tone while transmitting or receiving, the tone is controlled by operating the dome switch 13 installed inside the main body 1 by operating the side key 9 coupled to the side of the main body 1. Will be adjusted.

However, in the portable terminal having the above structure, the FPC 11 is fixed to the PCB 7 by soldering and fixed to the support 12, and the dome switch 12 is attached to the adhesive sheet on one side thereof. By being formed in a structure fixed by, there is a problem that the manufacturing process is complicated and the number of parts is large, the production labor and manufacturing cost increases.

An object of the present invention devised in view of the above point is to provide a side key assembly structure of a portable terminal to improve the structure in which the side key is mounted to reduce the number of parts and to facilitate manufacturing.

1 is an exploded perspective view of a conventional portable terminal.

Figure 2 is a partial cross-sectional view of a conventional side key assembled state.

Side key assembly structure of the portable terminal for achieving the object of the present invention as described above is a folder is coupled to the hinge of the upper side of the main body, the charge and discharge battery is detachably coupled to the rear of the main body In the portable terminal in which the PCB is built into the inner space of the upper cover and the lower cover of the main body, a side key is coupled to the side of the main body, and the front side of the side key is switched by the side key. The dome switch is installed so as to be electrically connected, and the other end is provided with a connecting member in electrical contact with the PCB.

Hereinafter, a side key assembly structure of a portable terminal according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a perspective view of a portable terminal having a side key assembly structure according to an embodiment of the present invention, and as shown, a portable terminal having a side key assembly structure according to an embodiment of the present invention is hinged at an upper end of a main body 101. The folder 102 is coupled to each other by opening and closing, and an LCD 103 for displaying information is coupled to an inner surface of the folder 102, and a charge and discharge is provided on a rear surface of the main body 101.
