Description
Technical field
This utility model relates to a kind of sealing shroud, key switch and keyboard.
Background technology
Keyboard is a kind of computer peripheral device, and keyboard has multiple button, and via pressing the plurality of button with defeated
Enter signal or instruction and be transferred to computer, wherein for operating characteristics, pressing life-span, key stroke and the manipulator of button
Sense has the highest requirement.
Each button of existing keyboard, the button of key switch moves up and down at button cover window, because on ensureing
The motility of lower motion, so all can leave certain gap.And button cap is all directly to be socketed on the button of key switch,
Lack outer protection, when user beats button, owing to easily being formed at key inside when the button cap of keyboard is pressed rear resilience
Negative inspiratory pressure, the gap easy inspiration dust at key switch or foreign material, thus affect the performance of button, and be difficult to keep surface
Cleannes.If user is in use accidentally when surface of keyboard watering or liquid beverage etc., due to button cap and button
Not having sealing protection outside the junction of shift knob, liquid will flow directly at the key switch of keyboard so that it is cannot obtain
To effectively protection, significantly impact stability and the service life of keyboard.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of sealing shroud, this sealing shroud can be applied
Outside in key switch button Yu button cover bonding pad, it is possible on the basis of not changing key switch feel and function, have
Effect solves the problems referred to above.
This utility model adopts the technical scheme that: a kind of sealing shroud, including central authorities bonding pad, center press district, encirclement
Described center press district and the deformed area being connected with described center press district and the seal area being connected with described deformed area；Described
