Abstract

The utility model relates to a novel laptop keyboard, comprising a plurality of button caps distributed at intervals, a plurality of scissor-like pins and a plurality of elastic colloidal silica bodies, a plurality of lower pin fixing bases, a middle board of a keybaord, a printing circuit thin film and a bottom board of the keyboard. Upper pin fixing bases are arranged on the bottom surface of the button cap, the upper pins of the scissor-like pins are inserted and fixed on the upper pin fixing bases while the lower pins of the scissor-like pins are inserted and fixed on the lower pin fixing bases. Each lower pin fixing base and the middle board of the keyboard form a plastic piece integrally injected and formed by plastic materials. The printing circuit thin film is arranged at the bottom of the middle board of the keyboard and the bottom board of the keyboard is arranged at the bottom of the printing circuit thin film. The middle board of the keyboard is provided with a plurality of throughholes and the elastic colloidal silica bodies penetrate through corresponding throughholes and lean against bottom surfaces of corresponding button caps corresponding to the scissor-like pins. The bottoms of the elastic colloidal silica bodies are fixed on the button switch of the printing circuit thin film. The keyboard provided by the utility model simplifies the production process of printing and saves the production cost.

Description

A kind of novel keyboard of notebook computer

Technical field

This novel computer keyboard technique field that relates to relates in particular to a kind of novel keyboard of notebook computer.

Background technology

Along with the development of information industry, notebook computer has obtained increasingly extensive application.The keyboard structure of existing notebook computer mostly is from top to bottom to be combined by button cap, scissors pin, printed circuit film and four parts of base plate; Wherein, The following pin of scissors pin is plugged on the following pin holder on the base plate after need passing printed circuit film; This structure must have several through holes at printed circuit film and supply the following pin of scissors pin to pass, and the complex process of making the P.e.c. of perforate, typography needs wire jumper to get around through hole realization connection; So; Production cost with printed circuit film of through hole increases than the production cost of atresia printed circuit film greatly, in view of this, how to improve existing keyboard of notebook computer structure and reduces production costs to become problem to be solved is arranged.

Summary of the invention

This novel purpose is exactly that provide to the weak point of prior art a kind of avoids the printed circuit film perforate, thereby simplified the novel keyboard of notebook computer that print production technology has been practiced thrift production cost.

For achieving the above object; This novel technical scheme is: a kind of novel keyboard of notebook computer; Include: some button caps spaced apart, with button cap one to one several scissors pin and several flexible silicon colloids, with the following pin of several scissors pin several plate, printed circuit film and keyboard boards in pin holders, the keyboard down one to one; Said button cap bottom surface is provided with the pin holder; After the assembling; The last pin of scissors pin is pegged graft and is fixed on the pin holder, and the following pin of scissors pin is pegged graft and is fixed on down on the pin holder, and plate is the same plastic parts by the plastic material integrated injection molding in said each following pin holder and the said keyboard; Printed circuit film is located at the bottom of plate in the keyboard; Bottom at printed circuit film is provided with keyboard board; In keyboard, have several through holes on the plate; The flexible silicon colloid is conflicted on corresponding key cap bottom surface after passing corresponding through hole and corresponding scissors pin mesopore successively, and the bottom of flexible silicon colloid is fixed on the keyswitch of printed circuit film.

Plate, following pin holder integrated injection molding in through hole in the said keyboard on the plate, the keyboard.

Said pin holder down and said keyboard board are by ABS or PC or PC and ABS or POM or nylon or PMMA and ABS or PMMA or the injection mo(u)lding of PBT plastic material.

After adopting said structure; The keyboard board that this novel one side adopts aluminium sheet to make tradition is improved to plate in the keyboard that plastic material processes; Pin holder, through hole and keyboard board integrated injection molding are same plastic parts with replacing with down in the structure that directly strikes out pin holder under the hook-shaped one-tenth of several fixed card on the aluminium sheet originally, and its sound construction degree of accuracy is high and reduced raw-material cost, has simplified production technology; Reduced production cost; Improve the degree of accuracy and the robotization efficiency of assembling of assembling, be fit to automated production, guaranteed product quality.On the other hand; This novel below that printed circuit film is arranged on plate in the keyboard with following pin holder; The flexible silicon colloid passes successively in the keyboard and conflicts on the button cap bottom surface behind the through hole on the plate and scissors pin; So just make printed circuit film avoid perforate, overcome the complicacy of the technology of traditional perforate P.e.c., practiced thrift production cost thereby simplified print production technology greatly.

Fig. 2 is the structural representation of plate in this novel keyboard.

Embodiment

Shown in Fig. 1-2; A kind of novel keyboard of notebook computer that this is novel; Include: some button caps spaced apart 10, with button cap 10 one to one several scissors pin 20 and several flexible silicon colloids 30, with the following pin 21 of several scissors pin 20 several plate 50, printed circuit film 60 and keyboard boards 70 in pin holders 40, the keyboard down one to one; Said button cap 10 bottom surfaces are provided with the pin holder; After the assembling; The last pin of scissors pin 20 is pegged graft and is fixed on the pin holder, and the following pin 21 of scissors pin 20 is pegged graft and is fixed on down on the pin holder 40, and plate 50 is the same plastic parts by the plastic material integrated injection molding in said each following pin holder 40 and the said keyboard; Printed circuit film 60 is located at the bottom of plate 50 in the keyboard; Be provided with keyboard board 70 in the bottom of printed circuit film 60; In keyboard, have several through holes 51 on the plate 50; Flexible silicon colloid 30 is conflicted on corresponding key cap 10 bottom surfaces after passing corresponding through hole 51 and corresponding scissors pin 20 mesopores successively, and the bottom of flexible silicon colloid 30 is fixed on the keyswitch of printed circuit film 60.

Plate 50, following pin holder 40 integrated injection moldings in through hole 51 in the said keyboard on the plate 50, the keyboard.

Said pin holder 40 down is by ABS or PC or PC and ABS or POM or nylon or PMMA and ABS or PMMA or the injection mo(u)lding of PBT plastic material with said keyboard board 50.

During use, finger is keypad cap 10 down, and button cap 10 presses down the top of flexible silicon colloid 30; Make the keyswitch of pressing printed circuit board film 60 under the bottom of the flexible silicon colloid 30 that is arranged in keyboard plate 50 through holes 51 belows, the switch-on keying circuit working, the scissors pin 20 here plays the effect of support fixation button cap 10; After unclamping finger; Under the elastic force effect of flexible silicon colloid 30, button cap 10 resets, and the keyboard board 70 here plays the effect of supporting printing board film 60.

This novel below that printed circuit film 60 is arranged on plate 50 in the keyboard with following pin holder 40; Flexible silicon colloid 30 is conflicted on button cap 10 bottom surfaces after passing in the keyboard through hole on the plate 50 51 and scissors pin 20 mesopores successively; So just make printed circuit film 60 avoid perforate; Overcome the complicacy of the technology of traditional perforate P.e.c., practiced thrift production cost thereby simplified print production technology greatly.
