Abstract

The utility model discloses a keyboard shrapnel binding layer which is used to hold keyboard shrapnels; and the keyboard shrapnel binding layer is provided with a pluratliy of lugs which correspond tothe keyboard shrapnels and are used for providing deformation space for the same, so that the working surface of each keyboard shrapnel is fully kept within the protection scope of the keyboard shrapnel binding layer. When the overall damp-proofing, dust-proofing, anti-corrosion and other protection measures of a keyboard have defects, no gap is left between the keyboard shrapnels and the keyboard shrapnel binding layer, so water, dust or other corrosive substances can not invade the keyboard shrapnels directly and do not affect the normal work thereof, so the service life of the keyboard shrapnels can be prolonged, and then the whole keyboard can better work. The utility model also discloses the keyboard with the keyboard shrapnel binding layer.

Description

A kind of keyboard and keyboard shell fragment binding layer thereof

Technical field

The utility model relates to electronic applications, and particularly a kind of keyboard shell fragment is bound layer and had the keyboard of this keyboard shell fragment binding layer.

Background technology

In the current rapidly society of information flow, computer has been the indispensable instrument of every profession and trade.The kind of computer and style also grow with each passing day along with its function and make rapid progress.Yet, no matter be the computer of which kind of style, the interface that its possess and user link up remains based on keyboard, how to improve keyboard structure preciseness, increase its useful life, become the target that all big enterprises research and develop.

Fig. 1 is the perspective exploded view of traditional design keyboard, as shown in Figure 1, this keyboard comprises key panel 201, keyboard 204, keyboard liner plate 202, water-proof silica-gel 203, binding layer 205, spacing layer 206, keyboard shell fragment 208, circuit board 207, keyboard board 209.This key panel 201, keyboard liner plate 202, water-proof silica-gel 203, binding layer 205, spacing layer 206, circuit board 207 and keyboard board 209 are superimposed successively to fit together by the weldering of the kind on the key panel 201 screw 201b location, this keyboard 204 is fixedly arranged between this key panel 201 and this keyboard liner plate 202, this keyboard shell fragment 208 is fixedly arranged between this binding layer 205 and this spacing layer 206, on keyboard board 209, be fixed with nut at last, tighten fixing above all parts.

This spacing layer 206 is two-sided gum thin plate, and it simultaneously sticks on this circuit board 207, and this spacing layer 206 is provided with the square groove that holds this keyboard shell fragment 208, and the another side of this spacing layer 206 bonds together with binding layer 205.In order to locate this keyboard shell fragment 208, this binding layer 205 is being opened circular hole 205a to position that should keyboard shell fragment 208, utilize circular hole 205a edge that this keyboard shell fragment 208 is limited in the square groove of this spacing layer 206, and limit the degree of freedom that it moves up and down perpendicular to this circuit board 7.

When keyboard is seated, the working face of this keyboard shell fragment 208, promptly relative with keyboard face 204 not in the protection range of this binding layer 205, that is to say that the working face of this keyboard shell fragment 208 directly contacts water-proof silica-gel 203 fully.When there is leak in safeguard measures such as keyboard integral body is moistureproof, dustproof, anticorrosion; owing to have the gap between this keyboard shell fragment 208 and this binding layer 205; moisture, dust or other corrosive substances can directly be invaded this keyboard shell fragment 208; make it cisco unity malfunction; shorten its useful life, and then influence the function of whole keyboard.

Therefore, demand urgently providing a kind of improved keyboard binding layer and keyboard to overcome above-mentioned defective.
