Abstract
The utility model discloses a static proof keyboard including an upper lid and a lower lid of a keyboard, a keystoke assembly, a PCB and a printed circuit thin film, in which a conductive material is attached on a contact face between the printed circuit thin film and the keystoke assembly to form a conductive layer, a static discharging loop can be formed in time during a keyboard operation so as to protect an integrate circuit for protecting the keyboard from being attacked by static, and the utility model has advantages of simple structure, low cost, etc.
Description
Technical field
The utility model relates to a kind of antistatic keyboard.
Background technology
Present keyboard use comfort and function are more and more perfect.Keyboard if any increasing microphone and horn function has and can warm oneself and the dustproof keyboard, has pair keyboard each several part shape to improve the raising operator and uses comfort or the like.Because the contact-making surface of button assembly and printed circuit film is easy to generate static,, might make keyboard integrated circuit destruction under attack even have influence on the operator if untimely static is eliminated.
Summary of the invention
The purpose of this utility model is to provide a kind of antistatic keyboard that can in time the static that produces be eliminated.
To achieve these goals, the utility model adopts following technical scheme: comprise the keyboard upper and lower covers, and button assembly, pcb board and printed circuit film adhere to conductive materials on the printed circuit film, and conductive materials is connected with ground wire.Contact-making surface at printed circuit film and button assembly is provided with one deck conductive materials and constitutes the loop, and on certain point of loop, be connected with ground wire, being equivalent to whole loop is ground connection, thereby contact with button assembly or other reason when producing static at printed circuit film, can in time the static that produces be eliminated by the galvanic circle.
As a kind of optimal way of technique scheme, form conductive layer on the contact-making surface of conductive materials attached to printed circuit film and button assembly, conductive materials is connected with the ground wire of pcb board.
Further improvement as above-mentioned preferred version, conductive layer can cover whole printed circuit film, also can on whole printed circuit film, distribute as net shape, and adhere to conductive materials and be in the latticed galvanic circle or other similar pattern distribution at the location hole periphery, its objective is to make whole printed circuit film each point have the galvanic circle as far as possible, thereby make the static that produces in time eliminate.The leading point that conductive layer is connected with the ground wire of keyboard pcb board be arranged on printed circuit film switching node near, connect for convenience.
The utility model is owing to adopt technique scheme; on the contact-making surface of printed circuit film and button assembly, form the static discharge loop; advantages such as thereby the integrated circuit of protection keyboard is not attacked by static, and the utlity model has simplicity of design, and is with low cost.
Description of drawings
Fig. 1 is a kind of partial structurtes schematic diagram of the present utility model;
Fig. 2 is the structural representation of conductive layer of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described by specific embodiment.
As shown in Figure 1, the utility model comprises keyboard upper and lower covers 1,2, button assembly 3 and printed circuit film 4, on the contact-making surface of printed circuit film 4 and button assembly 3, adhere to conductive materials, specifically be by the upper surface of method of printing with conductive materials attached to printed circuit film 4, also can adopt plating or other physics and chemical method, selected material is the silver slurry, can certainly select other conductive materials for use.As shown in Figure 2, conductive layer 5 attached to printed circuit film 4 distributes as net shape, with the conductive layer 5 of circular silver slurry and be in the latticed galvanic circle, conductive layer 5 can cover whole printed circuit film or other similar pattern distributes at location hole 8 periphery.The leading point 6 of the discharge loop that conductive layer 5 forms be positioned at printed circuit film 4 switching node 7 near; and this leading point 6 is connected with the ground wire of keyboard pcb board 9; make whole discharge loop link to each other with ground; when keyboard operation, can in time form the static discharge loop, thereby the integrated circuit of protection keyboard is not attacked by static.
