Title:
BUTTON STRUCTURE FOR DENT RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2017/143867
Kind Code:
A1
Abstract:
The present invention relates to the technical field of power supply device and technology. Disclosed is a button structure for dent resistance. The structure comprises: a button switch (1), a PCB (2), and a structural body (3) provided from top to bottom in that order. Edges of the PCB (2) are placed on top of the structural body (3) for support. An upper surface of the structural body (3) is provided with a protrusion (4) positioned below the PCB (2). Said protrusion (4) of the present solution being provided on the upper surface of the structural body (3) below the PCB (2) supports said PCB (2), thereby improving reliability of button use and resistance against deformation of the PCB (2), and can effectively prevent denting of the PCB (2).
