Description
Technical field
The present invention relates to PKB photoelectric keyboard switching technique field, more particularly, to a kind of thin shaft mechanical of the stronger photoelectricity of paragraph sense
Keyboard switch.
Background technology
Keyboard divides according to switch control principle, can probably be classified as five classes, be thin film type keyboard, conductive rubber respectively
Formula keyboard, contactless electrostatic capacity type keyboard, mechanical keyboard, and PKB photoelectric keyboard.Mechanical keyboard is current computor-keyboard
The main flow in market, its operation principle are that keyboard bottom possesses a circuit board, and individual mechanical axis more than 100, each axle are fixed on plate
It is independent switch, by pushing mechanical axis product signal will be made to be conducted by circuit board to computer, complete this and seem very
Simple signal transmission work.
Photoelectric key board is emerging keyboard in recent years, and it is on traditional mechanical key axle technical foundation, is added brand-new
Optoelectronic induction identification technology, it is optical sensor component by replacing traditional contact plectrum, improves conventional contact mechanical switch
Some problems.It utilizes optical principle and photoelectric coupling technology, and the path of light, light blocking are formed by light-emitting component and photo detector
Part priming photo-coupler in the cut-out of light path and closing course is carried out, change the break-make that circuit resistance value completes circuit, so as to
The conversion of electricity-light-electricity, and then disconnection and the path of controlling switch are realized, and photoelectricity is mutually isolated between input and output.Phase
Than in other keyboards, PKB photoelectric keyboard has following advantage：1. optical axis keyboard uses state-of-the art axle, optical axis keyboard is than commonly thin
Film keyboard long lifespan, theoretical service life are unlimited, can be used 50000 hours under continuous "on" position；2. optical axis keyboard makes
After long-time, handfeel of keys is varied less, and film is then unable to reach with standard machinery keyboard；3. optical axis keyboard can be done
Without punching more than to 104 keys, (therefore game player's use is especially suitable for, most of occupation electricity election contest hands can be all used without rushing button
Keyboard is improved the standard)；4. oneself button cap can be changed, facilitate individual character DIY；5. optical axis lower cover guide groove contacts with handle guide pillar
Position is widened, and using mould mirror surface manufacture craft product frictional force is smaller, more resistant, the life-span is more permanent；6. use high-quality qin
Steel wire spring, anti-fatigue performance is more preferable, screen resilience it is big switch switching action faster, sensitiveer, feel is more preferable；7. optical profile type is not deposited
It is sensitiveer, accurate in Mechanical Contact jitter problem, odds and ends news, the zero-lag of switch motion time, operation.
Applicants have discovered that at least there is following technical problem in prior art：
PKB photoelectric keyboard there is handfeel of keys it is single the problem of.PKB photoelectric keyboard paragraph sense in pressing keys is poor, uses
Feel is not fully up to expectations, therefore the user that the requirement for feel is high, and the game player especially especially valued operating handle comes
Say, they, which can only give up, operates sensitiveer, more accurately PKB photoelectric keyboard, and the mechanical keyboard of selection operation good hand touch.
While playing the advantage of PKB photoelectric keyboard, the feel of PKB photoelectric keyboard how is lifted, is that we will solve the problems, such as.
