Abstract

A portable terminal is characterized by comprising structure of: a shell comprising a front shell running through upper panel and forming a plurality of key holes, and a back shell combining with said front shell in thick direction and forming cooperation containing space inside; a printed circuit board (PCB) contained in the shell, having switch, and operating according to press operation to the front shell; a key zone comprising a plurality of keys inserted in said key holes, and can operate press to said switch, and a shell support section for supporting the front shell and connecting to said PCB and extending in thick direction. Thus the mobile terminal of the invention can increase the intensity of he shell, prevent static current flowing inside such that destroy of parts caused by static current inflow can be prevented.

Description

technical field [0001] The present invention relates to mobile terminals. More specifically, the present invention is a mobile terminal capable of enhancing the strength of a casing to prevent static electricity from flowing into the interior, thereby preventing parts from being damaged due to the static electricity flowing into it. Background technique [0002] figure 1 is an oblique view of an existing mobile terminal, figure 2 yes figure 1 The isolated oblique view of image 3 yes figure 2 The plane perspective view of the bonded state after removing the front shell in , Figure 4 yes figure 2 An enlarged cross-sectional view of the middle boss (boss) part. As shown in the accompanying drawings, the mobile terminal includes: a built-in bottom flip 21 of a printed circuit board (PCB) 41 capable of executing various functional programs; Closed upper flip cover 11. [0003] The upper flip cover 11 includes: a liquid crystal display panel 13 capable of outputting ...
