Abstract

The invention relates to a novel notebook keyboard, which comprises a plurality of key caps distributed at intervals, a plurality of scissors, a plurality of elastic silica colloids, a plurality of lower pin fixing seats, a keyboard middle board, a printed circuit film and a keyboard bottom board. Upper pin fixing seats are arranged on the bottom surface of the key caps. The upper pins of the scissors are fixedly socket-connected onto the upper pin fixing seats. The lower pins of the scissors are fixedly socket-connected onto the lower pin fixing seats. Each lower pin fixing seat and the keyboard middle board are the same one plastic piece which is integrally injection-molded by using a plastic material. The printed circuit film is arranged at the bottom of the keyboard middle board. The keyboard bottom board is arranged at the bottom of the printed circuit film. A plurality of through holes are arranged on the keyboard middle board. The elastic silica colloids sequentially penetrate through the corresponding through holes and the corresponding scissors and resist against the bottom surfaces of the corresponding key caps. The bottoms of the elastic silica colloids are fixed on the key switches of the printed circuit film. The novel notebook keyboard has the advantages that the printing production process is simplified and the production cost is saved.

Description

A kind of novel keyboard of notebook computer

Technical field

The present invention relates to the computer keyboard technique field, relate 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 by button cap, the scissors pin, four parts of printed circuit film and base plate from top to bottom combine, wherein, the following pin of scissors pin need pass on the following pin holder that is plugged on behind the printed circuit film on the base plate, 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 greatly than the production cost of atresia printed circuit film, in view of this, how improving existing keyboard of notebook computer structure reduces production costs to become problem to be solved is arranged.

Summary of the invention

Purpose of the present invention is exactly that provide at the deficiencies in the prior art part a kind of avoids the printed circuit film perforate, thereby simplified the novel keyboard of notebook computer that print production technology has been saved production cost.

For achieving the above object, technical scheme of the present invention is: a kind of novel keyboard of notebook computer, include: some button caps spaced apart, with button cap several scissors pin and several flexible silicon colloids one to one, with the following pin of several scissors pin several pin holders down one to one, plate in the keyboard, printed circuit film and keyboard board, described 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, 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 described each following pin holder and the described 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 described keyboard on the plate, the keyboard.

Described pin holder down and described 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 one aspect of the present invention adopts aluminium sheet to make tradition is improved to plate in the keyboard that plastic material makes, with originally on aluminium sheet, directly struck out several fixedly trip form down the structure of pin holder and replace with down that pin holder, through hole and keyboard board integrated injection molding are same plastic parts, its sound construction degree of accuracy height has also reduced raw-material cost, simplified production technology, reduced production cost, the degree of accuracy and the robotization efficiency of assembling of assembling have been improved, be fit to automated production, guaranteed product quality.On the other hand, the present invention is arranged on printed circuit film the below of 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 complexity of the technology of traditional perforate P.e.c., saved production cost thereby simplified print production technology greatly.

Fig. 2 is the structural representation of plate in the keyboard of the present invention.

Embodiment

Shown in Fig. 1-2, a kind of novel keyboard of notebook computer of the present invention, include: some button caps spaced apart 10, with button cap 10 several scissors pin 20 and several flexible silicon colloids 30 one to one, with the following pin 21 of several scissors pin 20 several pin holders 40 down one to one, plate 50 in the keyboard, printed circuit film 60 and keyboard board 70, described 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, 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 described each following pin holder 40 and the described 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 described keyboard on the plate 50, the keyboard.

Described pin holder 40 down and described keyboard board 50 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.

During use, finger is keypad cap 10 down, 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.

The present invention is arranged on printed circuit film 60 below of plate 50 in the keyboard with following pin holder 40, flexible silicon colloid 30 passes successively in the keyboard and conflicts on button cap 10 bottom surfaces behind the through hole on the plate 50 51 and scissors pin 20 mesopores, so just make printed circuit film 60 avoid perforate, overcome the complexity of the technology of traditional perforate P.e.c., saved production cost thereby simplified print production technology greatly.
