Abstract

The invention discloses a terminal. The terminal comprises a middle frame, a side key body and a flexible circuit board, wherein the flexible circuit board comprises a circuit board body and a feed point; a side key groove which does not fully run through the inner wall is formed in the frame edge of the middle frame in a direction from the outer wall to the inner wall; the shape and the size of the side key groove are matched with those of the side key body, and the side key groove is used for accommodating the side key body; a circuit board groove which does not fully run through the bottomsurface of the frame edge is formed in the frame edge from the top surface of the frame edge downwardly; the circuit board groove is connected with the side key groove in the frame edge; the circuit board groove is used for accommodating the circuit board body; the circuit board body is provided with keys, and the keys are corresponding to the positions of key legs on the side key body in a matching manner; the feed point is electrically connected with the keys, and extends to the interior of the frame edge through the opening of the circuit board groove; and the side key groove does not directly and horizontally run through the inside and outside of the middle frame, so that water drop immersion to the interior of the terminal from the opening of the side key groove can be blocked to a certain degree, thereby improving the waterproof performance of the terminal.

Description

technical field [0001] The present invention relates to the technical field of terminal side key waterproofing, and more specifically, relates to a terminal. Background technique [0002] At present, the terminal side key setting scheme is almost always to set the side keyway on the middle frame horizontally through the outer wall of the frame to the inner wall of the frame. Please refer to figure 1 , the side key groove is used to install the side key body 12 matched with it, and the side key body 12 is provided with a key leg 121; while the FPC (Flexible Printed Circuit, flexible circuit board) assembly 13 is fixedly bonded on the inner shell of the terminal , the FPC assembly 13 is fixedly provided with a switch button 131 (such as the volume up key, volume down key, power button, etc. of the terminal), after the FPC assembly 13 is fixed and bonded, the position and side of the switch button 131 on the FPC assembly 13 The positions of the key legs 121 on the key body are...
