Abstract

The invention, which relates to the communication device field, discloses a side key assembly and a terminal device. The side key assembly applied to the terminal device comprises a flexible circuit board (FPC) and a resistance strain gauge. The resistance strain gauge includes a sensitive grid region and pins led from the sensitive grid region. Copper exposure regions corresponding to the pins one by one are arranged on a first surface of the FPC; the resistance strain gauge is pasted on the first surface of the FPC; and the pins are connected to the copper exposure regions electrically. In addition, the invention also discloses a terminal device. Compared with the prior art, the side key assembly and the terminal device has an advantages that poor contact between the side key assembly and the circuit board can be avoided.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a side key assembly and a terminal equipment. Background technique [0002] In recent years, with the continuous development of communication technology and the continuous progress of the times, mobile devices such as mobile phones, computers, etc. have become indispensable tools in people's daily life. This is because mobile phones or computers are easy to carry and easy to use. life has brought great convenience. [0003] The existing mobile device side key assembly is mainly realized by metal pins. The working principle of the side key of this structure is that the metal metal pin is located on the conductive part of the flexible circuit board FPC. When pressed, the central point of the metal metal pin falls Concave, contacting the exposed copper area on the FPC, thus forming a loop with the periphery of the dome, the current passes through, and the switch function of t...
