Abstract

The invention discloses a double-contact keyboard key structure. The structure comprises a key cap, a movable shaft body, a middle plate body, silica gel, a conductive film and a backlight board. Thebacklight board and the conductive film are stacked; the top end of the silica gel extends inward to form a conductive portion; the conductive portion and the conductive film are in contact connection; the top end of the silica gel is fixedly connected with the bottom end of the movable shaft body; the upper portion of the movable shaft body is fixedly arranged in the key cap, and the lower portion of the movable shaft body is movably arranged in the middle plate body and can move up and down; the inner wall of the middle plate body is fixedly provided with a metal spring piece; the metal spring piece is provided with two contact point; the outer wall of the movable shaft body is provided with two contact point grooves capable of accommodating corresponding contact points; and each contactpoint is in contact connection with the corresponding contact point groove. The double-contact design enables key sound and hand feel performance stability to be good; contact points are resistant towear and do not influence sound and hand feel; and the service life is long and mould processing is easy.

Description

technical field [0001] The invention relates to the field of keyboard keys, in particular to a double-contact keyboard key structure. Background technique [0002] Existing keyboard keys usually use a single point structure to realize the process. This structure has poor hand feel and sound stability, and the contacts are not wear-resistant, have a short life, and the mold processing is difficult; therefore, it is difficult to use and process. All brought great inconvenience. [0003] Patent application 200810176171.4 discloses a dual-contact keyboard device, which may include a plurality of keys and a keyboard controller. Each key of the plurality of keys may include at least one actuation contact and a plurality of sense contacts. Each drive contact can be connected to the output (drive) line of the keyboard decoder, and each sense contact can be connected to the input (sense) line of the keyboard decoder, so that each key is connected to a unique sense line combination...
