Description

The button of dustproof and anti-water-sprinkling

Technical field

The utility model relates to a kind of button (Keyswitch), in order to prevent the damage that button causes because of water inlet and to improve button useful life.Especially, the utility model is about making deformable guard shield (Shielding) distortion together during the moving of keycap (Keycap), and covered substrate (Substrate), switch (Switch) and bracing or strutting arrangement (Supporting device) are to reach the purpose of dustproof and waterproof.

Background technology

Growth along with informatization, information equipment is also and then universal day by day, with regard to the computer of normal contact, various label and pattern are not only being arranged on the market, its feeler more extends to places such as family, factory, company, office and school, its use aspect even be popularized for each stratum has almost become the daily essential product of people; Relatively, how to go to safeguard that computer in operational validity and prevent that this type of high-tech product is impaired, then becomes the emphasis that everyone can notice.

Yet the easiest often peripheral device that is subjected to polluting infringement of keyboard anyly swims in airborne small dust, or cigarette ash of dropping accidentally of user, beverage, water droplet etc., all can make keyboard impaired, influences the useful life of computer.

In order to solve problem dustproof and the room water-sprinkling, be so that the improvement of various press-key structure to be arranged, a kind of existing waterproff keyboard is for example arranged, as No. 236428 those disclosed herein of TaiWan, China patent gazette Announcement Number, it mainly is to cover to be provided with most corresponding column pipes and perforation under the loam cake bottom surface reaches, and moisture is imported in the liquid-collecting box of lower cover bottom surface setting by column pipe, available to prevent that flow of liquid from going into circuit unit, only this kind design, its structure is comparatively complicated, column pipe and perforation need be laid on the whole card, cause the inconvenience in the manufacturing.Moreover it is when being collected in liquid the keyboard storage, if stir keyboard because of carelessness, the liquid that then is stored in keyboard will upwards reflux, and causes severe impairment.

Therefore, for fear of the generation of this situation, category of the present utility model is to provide a kind of button of dustproof and anti-water-sprinkling, and it is to utilize that deformable guard shield is isolated below keycap to pollute infringement, in order to reduce the button spoilage and to improve button useful life.

The utility model content

The purpose of this utility model is to provide a kind of button, to reduce the button spoilage and to improve button useful life, and can make the distortion together during the moving of keycap of deformable guard shield, and covered substrate, switch and bracing or strutting arrangement are to reach the purpose of dustproof and waterproof, by button of the present utility model,, the user reduces to minimum in addition so that can damaging the button that environmental factor caused chance.

The purpose of this utility model is achieved in that promptly provides a kind of button (keyswitch) to comprise a substrate (Substrate), a switch (Switch), a bracing or strutting arrangement (Supporting device), a deformable guard shield (Shielding) and a keycap (Keycap).This switch is fixed on this substrate.This bracing or strutting arrangement has a junction on (Upper engagement portion) and a following junction that is connected with this substrate (Lower engagement portion).This deformable guard shield has a top (Top portion), and this guard shield is arranged on this substrate and covers this switch and this bracing or strutting arrangement, and wherein this top is provided with a plurality of holes (Aperture).This keycap itself limits a lower surface and has a plurality of fixed mounts (Retaining lug) that are formed on this lower surface, alternatively, these holes that these fixed mounts pass this top are connected to go up junction with being somebody's turn to do of this bracing or strutting arrangement, or the junction of should going up of this bracing or strutting arrangement passes these holes at this top to be connected with these fixed mounts.And according to button of the present utility model, this bracing or strutting arrangement supports the vertical moving of this keycap work with respect to this substrate, and this switch is that mobile the electing property ground of responding this keycap is opened.

Advantage of the present utility model is, its button can be by being provided with the function that deformable guard shield reaches dustproof and anti-water-sprinkling between keycap and supporting member, and exempted the situation that liquid is directly invaded keyboard.

Can describe in detail and appended graphic being further understood by following utility model about advantage of the present utility model and spirit.
