An electrostatic prevention key structure

Abstract

The invention provides an antistatic keying structure, comprising a keying stroke spring plate, an elastomer arranged on the keying stroke spring plate and a plurality of metal keycaps combined on the elastomer; wherein, the upper part of the metal keycap forms a conductive metal part, the lower part of the metal keycap forms an insulating base part which is jointed between the elastomer and the conductive metal part. Adopting the antistatic keying structure of the invention not only leads the keying to have metal effect, but also can prevent the electrostatic discharge of the metal keycaps effectively.

Description

technical field [0001] The invention relates to a button used on electronic products, in particular, an antistatic button structure. Background technique [0002] Buttons are common parts of electronic products. Such as figure 1 As shown, the existing key structure generally includes a DOME (key travel elastic sheet) 91 placed on the PCB, an elastic body 92 on the DOME and a keycap 93 combined on the elastic body 92, which is exposed by the user through operation. The top of the key cap 93 outside the housing 90 is used for key operation. With the development of electronic technology, buttons made of metal effect (that is, the keycap of the button is a metal keycap) are more and more popular among consumers. At present, metal keys are usually formed by directly using metal materials to make metal keycaps or electroplating a metal layer on the surface of keycaps made of organic materials. [0003] However, the metal key structure formed by the metal key cap has the follow...
