Description

A kind of dustproof keyboard switch

Technical field

This utility model relates to keyboard switch field, particularly relates to a kind of keyboard switch with dust reduction capability.

Background technology

In existing keyboard switch, owing between button and upper cover, surrounding exists gap, during using for a long time, have dust enter the action matching mechanism within keyboard switch by gap, affect the normal use of keyboard switch, it is in particular possible to the problem that card key can be caused.

And, mechanical keyboard has tight demand as e-sports player and the important peripheral hardware of fan, versatility and commutativity to keyboard cover, and keyboard cover passes through long-run development, has formed structure and the size of industry de facto standard.Cylinder (mounting post) and the size such as cylinder external diameter of internal cruciform groove that keycap coordinates with mechanical axis are usually about 5.8mm.

Utility model content

The technical problems to be solved in the utility model is that design one has good dust-proof effect, and the dustproof keyboard switch directly can arranged in pairs or groups with the keycap of industry standard, and in order to reach above-mentioned technical purpose, this utility model realizes in the following way:

A kind of dustproof keyboard switch, including base, upper cover and button, button periphery is provided with dustproof part, and dustproof part upwardly extends in button upper end along button edge, is provided with when keycap is installed the clearance position preventing from being formed between dustproof part and the mounting post of keycap interference in dustproof part.

As the improvement to such scheme, centered by described clearance position, it is symmetricly set in two breach of dustproof part both sides.

As further improvement of these options, breach extends button lower end from the top down, forms gap between button side walls and upper cover, and dust can directly fall to base bottom by gap.

And, described dustproof part upper surface is consistently higher than upper lid surface or concordant when moving up and down with button.

Described dustproof part includes the front shortwall around button upper edge edge, rear shortwall, left longwell, right longwell, and breach is positioned on left longwell, right longwell.

As the further improvement to such scheme, described front shortwall, rear shortwall, left longwell, the edge of right longwell are chamfering or fillet.

And, described dustproof part and button are the integrative-structure of injection mo(u)lding.

The dustproof keyboard switch that this utility model provides can the effectively using effect of blocks dust access switch internal influence parts and service life, and its cost is relatively low, only need to increase dustproof part on the basis of original keyboard switch, preferable dust-proof effect can be realized, directly mate with existing general QWERTY keyboard keycap, button cap structure and size need not be revised.

Detailed description of the invention

For ease of skilled artisan understands that the present invention, below in conjunction with the accompanying drawings and embodiment the utility model will be further described.

As shown in accompanying drawing 1,2,3,4,5.The dustproof keyboard switch that the present embodiment discloses includes base 1, upper cover 2 and button 3, and the keycap of keyboard is installed on the upper end of button 3, and keycap 6 inner surface has the mounting post 61 being tightly placed in button 3 top.Two metal clips 7 connecting outside line are installed in base 1.Button 3 lower end connects driven member 31, and driven member 31 is installed in base 1 and (can also be structure as a whole between driven member 31 and button 3 and not use separate form, as shown in Figure 8).Button 3 lower end has newel 32, and newel 32 is cased with spring 8, and spring 8 upper and lower side peaks at button 3 lower surface and base 1 inner surface respectively.Upper cover 2 and base 1 form an inner space, button 3, driven member 31 and spring 8 can in inner space knee-action.

In the present embodiment, upper cover 2 upper surface is exposed on the top of this button 3 button 3.Mounting post 61 end face is provided with groove that shape and size mate with button 3 top (such as the cross bath of mounting post 61 end face in figure, this cross bath is also the size of the existing universal standard), after button 3 upper end is inserted in groove, the installation between keycap 6 and button 3 can be realized.In order to prevent button 3 dust when up and down from entering internal, this programme design is provided with dustproof part 4 in button 3 periphery, dustproof part 4 upwardly extends in button 3 upper end along button 3 edge, is arranged on the clearance position 41 preventing from being formed between dustproof part 4 and mounting post 61 interference when keycap 6 is installed in dustproof part 4.Diminish owing to setting up the dustproof part 4 space afterwards between button 3 upper end and upper cover 2, and the size of the mounting post 61 of existing keycap 6 has formed common-use size, should not change, therefore by setting up clearance position 41 in dustproof part 4, prevent dustproof part 4 from stopping the installation of mounting post 61, i.e. can reach dust-proof purpose, again can compatible existing keycap 6, the beneficially popularization and application of such keyboard switch.

Specifically, the dustproof part that the present embodiment uses includes the front shortwall around button upper edge edge, rear shortwall, left longwell, right longwell, and clearance position 41 is positioned on left longwell, right longwell.Clearance position 41 is nicked form, and centrosymmetry is arranged on left longwell, right longwell, and after the mounting post 61 of keycap 6 inner surface is inserted in button 3, mounting post 61 side enters in breach (the most as illustrated in 6,7), it is to avoid mounting post 61 is interfered with dustproof part 4.Nicked form clearance position 41 in this programme extends button 3 lower end from the top down, gap 411 is formed between button 3 sidewall and upper cover 2, dust directly can fall to bottom base 1 by gap, affect the use of key switch without being attached to other critical components, improve keyboard switch service life.

Simultaneously, it is considered to time outside dustproof part 4 with upper cover 2 relative motion, dust may be accumulated at corner location and affect the smooth and easy of relative motion, is chamfering or fillet at front shortwall, rear shortwall, left longwell, the edge of right longwell.

Additionally, in the present embodiment, dustproof part 4 and the integrative-structure that button 3 is injection mo(u)lding, this structure can be effectively improved button 3 processing and fabricating efficiency.Meanwhile, in order to improve dust-proof effect, when the upper surface of dustproof part 4 moves up and down, it is not less than upper cover 2 surface with button 3 all the time.

Above-described embodiment is only preferred embodiment of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these obvious alternative forms belong to protection domain of the present utility model.
