Split-type light-guide key switch and mechanical keyboard

Abstract

The invention discloses a split-type light-guide key switch and mechanical keyboard. The key switch comprises a key switch body, an optical crystal emitter device and an optical crystal receiver device, wherein the optical crystal emitter device and the optical crystal receiver device are arranged on a PCB. The key switch body comprises a housing and a press handle arranged on the housing. The optical crystal emitter device and the optical crystal receiver device are separated by a first light baffle device. A first light guider is arranged above the optical crystal emitter device. A second light guider is arranged above the optical crystal receiver device. Optical signals emitted by the optical crystal emitter device are transmitted back to the optical crystal receiver device through the first light guider and the second light guider. The press handle is provided with a second light baffle device for baffling the optical signals transmitted from the first light guider to the second light guider. Through the light guiders, not only the transmission stability of the optical signals is improved, but also cost and process requirement of the key switch are reduced, and meanwhile, precision and the service life of the mechanical keyboard are greatly improved.

Description

technical field [0001] The invention relates to a key switch and a mechanical keyboard, in particular to a split-type photoconductive key switch and a mechanical keyboard, belonging to the research field of mechanical keyboards. Background technique [0002] A mechanical keyboard is a common type of keyboard in which each key has an individual switch to control the closure. As a representative of high-end products, the mechanical keyboard has been welcomed by more and more computer users and game players. The switch generally used is a mechanical key switch of the metal material contact type. This switch is set in the casing Whether the metal material contacts of the static pressure plate and the dynamic pressure plate are in contact with each other to realize the on-off of the switch, during the displacement process of pressing the mechanical switch handle, the metal material contacts on the dynamic pressure plate and the metal material of the static pressure plate The mat...

AI Technical Summary

Problems solved by technology

With this scheme, the metal contacts of the mechanical switch are easily damaged, because in the process of pressing the button, the elasticity of the dynamic pressure plate will be greatly different from the original state with the increase in the number of uses, which will easily cause the metal contacts to fail. Sensitive or non-conductive state, limited service life, causing trouble to users

In addition, in the traditional mechanical keyboard, the optical crystal transmitting and receiving device is set in the key switch, the bottom pins are welded on the PCB board, and then the key switch is snapped into the card slot, and finally the fixed column on the rotating iron plate is fixed to the key switch. The PCB board is fixed to the iron plate, which makes it very troublesome to disassemble and repair once a button is damaged. Not only need to unscrew the fixing column, but also need to unplug the optical crystal receiving device and transmitting device from the PCB board. It is very difficult to handle, and it is easy to cause damage to the keyboard. At the same time, the conduction accuracy of this type of keyboard is limited by the distance between the PCB board and the iron plate, so it is not easy to control; in addition, this type of keyboard is not conducive to large-scale industrial production.
