Single geminate transistor reflective keyboard

Abstract

The invention discloses a single geminate transistor reflection keyboard which comprises a PCB and a plurality of geminate transistor switches, geminate transistors are installed on the lower side ofthe PCB, each geminate transistor comprises a baffle, an emitting electrode and a receiving electrode are installed on the two sides of each baffle, the geminate transistor switches are installed on the PCB, and each geminate transistor switch comprises a transparent upper shell, keys and a bottom shell. The key comprises a pressing head and a first reflector, the bottom shell comprises a second reflector matched with the first reflector in position, the second reflector is located on the lower side of the PCB, the two use schemes enable the use application effect to be good, and compared witha separated design in the prior art, the design that the emitting electrode and the receiving electrode are integrated is more novel, and the service life of the key is prolonged. The PCB is simple in structure, easy to produce and manufacture, compact in overall structure, long in service life, good in feedback effect and good in using effect, the geminate transistors are installed below the PCB, and compared with the mode that geminate transistors are installed above a PCB in the prior art, the dustproof and waterproof effects are better.

Description

technical field [0001] The invention belongs to the technical field of keyboards, and in particular relates to a single pair tube reflective keyboard. Background technique [0002] With the development and progress of science and technology, people's requirements for things have changed from the old thinking that can be used to become quite delicate and demanding. Only the idea of ​​continuous improvement or innovation will produce new forms to increase the added value of products. , in order to survive under the test of fierce market competition. Mechanical keyboards are favored by many computer users, programmers and gamers. Because each button has a separate switch to control the closure, the buttons have a strong sense of paragraph, resulting in a special feel suitable for gaming and entertainment. According to different classifications of switches, mechanical keyboards can be divided into brown switches, green switches, white switches, black switches and red switches, ...

AI Technical Summary

Problems solved by technology

[0004] However, for a mechanical keyboard using positive and negative shrapnel, the collision friction between the two is easy to cause wear, and then lead to unstable performance; in the prior art, the pair of tubes 2' is usually installed on the upper side of the PCB board 1', As a result, the effect of dustproof and waterproof is not good, and for the mechanical keyboard using the pair of tubes 2', the reflection method in the prior art mostly adopts a reflection plate, and there is only one reflection use scheme, resulting in a structure that is not compact enough. The manufacturing cost is relatively increased, it is not easy to be integrally injection molded, and the production efficiency is reduced
