Description
Technical field:
The utility model relates to computer peripheral equipment technical field, especially relates to a kind of mechanical keyboard key switch.
Background technology:
As shown in Figure 1: general mechanical keyboard generally uses the key switch of German cherry type, it has upper cover 4, base 1, axle core 2, spring 3 and contact flat spring 7,8; Have a sleeve pipe holded up 11 in the middle part of base 1, the transparent stand column 21 that falls of axle core 2 lower end slides in sleeve pipe 11.The characteristic of arranging in pairs or groups because of contact flat spring 7,8 and axle core 2 side makes so, the triggering stroke of the key switch of current cherry type is 2mm ± 0.4mm, because every part is produced indivedual tolerance, adding stack up result is that tolerance is very large, and is that each button is widely different; Because tolerance 0.4mm is bigger than normal, cannot shorten so trigger stroke 2.0mm, because if some product is in down in limited time, trigger Excessive sensitivity, thumb is once putting up conducting again.
Shorten and trigger stroke and have two kinds of modes: a kind of mode changes tortuous bow arcuate positions to make it be out of shape rapidly, but do not increase in causing gram, feel change greatly; Another mode changes silver point height, triggers ahead of time, but silver point can be caused easily to wear and tear.
Due to the pursuit of game mechanical keyboard is fast reaction, and therefore necessary otherwise designed, solves the problem that cannot shorten at present and trigger stroke.
Utility model content:
The purpose of this utility model is just the weak point that exists for prior art and provides a kind of mechanical keyboard key switch of quick percussion, and it has the advantages that production cost is low, percussion stroke is short.
For achieving the above object, mechanical keyboard key switch of the present utility model is welded on the printed circuit board (PCB) of mechanical keyboard, comprises base, axle core, upper cover, the first back-moving spring, the second back-moving spring, the first terminal and the second terminal; Wherein, upper cover is positioned at above base, axle core is between upper cover and base, guiding mechanism by being positioned at axle core and base central part between axle core and base is slidably matched mutually, the upper end of described the first terminal and the second terminal forms the first terminal horizontal part and the second terminal horizontal part in the difference bending of base upper surface place, and the lower end of the first terminal and the second terminal is connected on printed circuit board (PCB) through base; The length of the first back-moving spring is greater than the second back-moving spring and is in compressive state, on the conductive part that the two ends up and down of the first back-moving spring are against axle core lower surface respectively and base, and contact with the first terminal horizontal part, have vertical interval between one end of second back-moving spring and conductive part or the second terminal horizontal part, this spacing is the percussion stroke of key switch.
Preferred as technique scheme, the lower end of the second described back-moving spring contacts with base and the second terminal horizontal part, and upper end contacts with the guide vane end stop below upper cover and is in micro-compressive state, and and has vertical interval between conductive part.
Preferred as technique scheme, the lower end of the second described back-moving spring contacts with base and the second terminal horizontal part, and upper end is free end, and and has vertical interval between conductive part.
Preferred as technique scheme, the upper end of the second described back-moving spring contacts with conductive part, and lower end is free end, and and has vertical interval between base and the second terminal horizontal part.
Preferred as technique scheme, the diameter of the second described back-moving spring is greater than the first back-moving spring, and the first back-moving spring is positioned within the second back-moving spring.
Preferred as technique scheme, the second back-moving spring diameter close to the first back-moving spring, the first back-moving spring and the second back-moving spring arranged in parallel.
Preferred as technique scheme, the first described back-moving spring and the second back-moving spring have the vertical leads as solder terminal respectively.
Preferred as technique scheme, described base and top cap are integrated.
The beneficial effects of the utility model are: its structure can shorten key switch percussion stroke, do not have quality hidden danger, and can be high by carrying out minute-pressure shrinkage limit to the second back-moving spring, make the tolerance of actual height very little, the percussion stroke of different switch is very always; In addition, it also using the lead-in wire of back-moving spring as solder terminal, can need not use extra terminal, thus reduces production cost.
