Abstract
The utility model discloses a key switch dustproof construction, including upper cover, base, according to sincere, spring, moving plate and still, still and moving plate all set up in upper cover and base and enclose the holding intracavity that closes formation, but set up in the holding chamber through spring elasticity activity ground according to sincere, and the logical groove that has the confession to expose is opened according to sincere one end to the upper cover, the contact site of moving plate is acted on according to the sincere other end and on, the top of upper cover is equipped with dustproof lid, dustproof lid is including the lid top of swelling, formed at lid top lateral wall on every side, logical marge fits the encirclement within range of lateral wall, according to sincere including integrative connecting block portion and the button portion that links to each other, open at the lid top has the opening that supplies button portion to expose, connecting block portion forms the below that just is located the lid top in button troops under one's command side, it has the gap to separate between connecting block portion and the logical groove, opening and this gap position dislocation. The utility model discloses can reduce and avoid the dust to get into the holding intracavity even completely.
Description
Technical field
The utility model relates to a kind of key switch dustproof construction.
Background technology
Key switch is by button on guidance panel, makes the conducting of button the two poles of the earth, thus the signal transmission realizing key switch reaches the object of manipulation.At present, a kind of key switch that market uses, it comprises upper cover, base, by sincere, spring, moving plate and still, base is fastened on upper cover, be installed between upper cover and base by sincere, and can start between upper cover and base, drive the separation between still and moving plate and contact, to realize conducting and the disconnection of construction of switch, owing to lacking protector by between sincere and upper cover, unclamp after by sincere downward pressing when upspringing, due to the empty chamber air ecto-entad flowing that upper cover and base are formed, cause in use procedure, very easily making dust enter from gap, switch easily causes switch loose contact after entering dirt, and be not easy to remove, reduce the reliability of switch.
At present, each button of common mechanical keyboard has an independent switch to control to close, due to each button by one independently fine motion form, therefore button paragraph sense is comparatively strong, usually used as the ideal equipment of high end games peripheral hardware costly and programmer.Because mechanical keyboard adopts mechanical structure, clean dust and dust-proof comparatively difficulty, existing machinery keyboard dust-proof technology many employings dust cap or dustproof membrane, such as, publication number is the structure that CN02819317A discloses a kind of dustproof keyboard cover, and it is on keyboard, and setting is renovated; Some dusts, foreign material and some other tiny article effectively can be avoided to fall between the space of keyboard, thus avoid and overcome therefore having influence on facility environment health.But this technical scheme and known mechanical keyboard dust control technology have the deficiency affecting operating handle, the high-end player of game and programmer can not be met for the requirement of outstanding operating handle.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provide a kind of dust-proof while do not affect the key switch dustproof construction of feel.
The purpose of this utility model is achieved through the following technical solutions:
A kind of key switch dustproof construction, comprise upper cover, base, by sincere, spring, moving plate and still, described base is fastened on upper cover and forms containing cavity, this still and moving plate are all arranged at upper cover and base encloses in the containing cavity of formation, can elasticity should be arranged at actively in containing cavity by spring by sincere, upper cover has the groove for exposing by sincere one end, act on the contact site of moving plate by the sincere other end, the contact site of this moving plate separates with contacting with the contact site of still to connect or depart from by sincere activity, it is characterized in that: the top of described upper cover is provided with a dust-proof lid, described dust-proof lid comprises the lid top of protuberance, be formed at the sidewall around lid top, described groove encloses within the scope of the encirclement of described sidewall, described by sincere comprise one be connected contiguous block portion and button portion, described lid top has the peristome exposed for button portion, described contiguous block portion to be formed in below button portion and to be positioned at the below at lid top, gap is separated with between described contiguous block portion and groove, described peristome and this gap position misplace.
Concrete, described dust-proof lid and upper cover are integral seamless integrated formed structure.
The utility model has the following advantages and beneficial effect compared to existing technology:
The utility model is by adding a dust-proof lid in upper cover position, and the peristome of this dust-proof lid and the gap position between contiguous block portion and groove misplace, thus changes the direction of air flowing, and can reduce and avoid dust to enter in containing cavity even completely; Said structure does not affect the original structure of key switch, ensures the serviceability of switch.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram of the utility model key switch dustproof construction.
Fig. 2 is the structural representation of upper cover and dust-proof lid.
Fig. 3 is the package assembly schematic diagram of the utility model key switch dustproof construction.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, the present embodiment provides a kind of key switch dustproof construction, comprise upper cover 1, base 2, by sincere 3, spring 4, moving plate 5 and still 6, described base 2 is fastened on upper cover 1 and forms containing cavity, this still 5 and moving plate 6 are all arranged at upper cover 1 and enclose in the containing cavity of formation with base 2, can elasticity should be arranged at actively in containing cavity by spring 4 by sincere 3, upper cover 1 has the groove 101 for exposing by sincere 3 one end, the other end by sincere 3 acts on the contact site of moving plate 4, the contact site of this moving plate 5 separates with contacting with the contact site of still 6 to connect or depart from by sincere 3 activities, the top of described upper cover 1 is provided with a dust-proof lid 7, described dust-proof lid comprises the lid top 701 of protuberance, be formed at the sidewall 702 around lid top 701, described groove 101 encloses within the scope of the encirclement of described sidewall 702, described by sincere 3 comprise one be connected contiguous block portion 301 and button portion 302, described lid top 701 has the peristome 703 exposed for button portion 302, described contiguous block portion 301 to be formed in below button portion 302 and to be positioned at the below at lid top 701, gap is separated with between described contiguous block portion 301 and groove 101, described peristome 703 misplaces with this gap position.
As Fig. 2 and Fig. 3, described dust-proof lid 7 is integral seamless integrated formed structure with upper cover 1.By said structure, both operation can simplify, the consumption of attached raw material can be reduced again.
