Side keys and mobile terminals

Abstract

The invention discloses a side key and a mobile terminal. The side key includes: a housing, including a key surface and a plate surface perpendicular to the key surface; the plate surface is recessed with a slot near the key surface, and the slot includes a The side wall of the first groove and the side wall of the second groove opposite to the side wall of the first groove; the surface of the key is recessed with a hollow hole, and the hollow hole passes through the side wall of the first groove; the first key body, It includes a first pressing portion located outside the key surface, and a connection structure inserted into the hollow hole; a hard plate, inserted into the slot, includes a flat plate portion against the side wall of the second groove, And the first protruding part connected with the flat part, the first protruding part abuts against the side wall of the first groove; the key flexible circuit board is fixed on the flat part of the hard board, the The key flexible circuit board includes a first switch corresponding to the first key body. The invention has the effects of improving installation efficiency and reducing production cost.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a side key and a mobile terminal. Background technique [0002] As the screen of the mobile terminal becomes larger, basically no mechanical buttons are arranged on the surface of the screen. And the mechanical key is arranged on the side of the mobile terminal. For example, currently common mobile terminals are provided with three keys on the side. They are power button, volume down button and volume up button. [0003] In order to be able to install the above three buttons, the current commonly used solution is to paste the flexible circuit board FPC of the three buttons on the casing of the mobile terminal through double-sided tape, and then insert the three buttons into the casing through a separate buckle The part of the button is buckled, so as to realize the installation of three buttons. [0004] However, the current structure leads to low efficiency and high cost of s...

Problems solved by technology

[0004] However, the current structure leads to low efficiency and high cost of side keys during installation

The position where the flexible circuit board FPC needs to be glued to the housing is very narrow, which makes it difficult to operate in assembly and low in efficiency

After the flexible circuit board FPC is attached to the shell, it needs to be adjusted, and when the flexible circuit board FPC is disassembled, it is easy to be scrapped, resulting in an increase in material costs

[0005] It can be seen from the above that the current structure of side keys leads to low assembly efficiency and high production costs
