Description

The Computer key switch

The utility model is about a kind of Computer key switch.

Computer was propagated its belief on a large scale in the society in today, because it has the function of a large amount of storages and fast processing information, therefore, had all replaced traditional manual work in a lot of fields.

The input of computer though many different instruments and mode are arranged, dare not be spoken carelessly, and is up to now still in the majority with keyboard input, even therefore PC also is to be that standard is equipped with the keyboard.

The key switch of keyboard can be as big as and is divided into mechanical type and diaphragm type, owing to pursue the light, thin, short, little of product, thus be many with diaphragm type and conductive rubber mode, and the mechanical trend of whole gradually replacements are arranged.The principle of diaphragm type is the contact through conductive rubber, touches the contact on the printing film of below after pushing, to reach the input of instruction.

In fact, because the competition day by day of information products, and key switch has upgrading on the function because of nothing resembles main frame, so, its pursuer only is to see through the simplification of element, reduces when making the assembler, and then reduces the cost of whole keyboard, thereby the raising market competitiveness, this is the developing direction of producer present stage and the unique channel of existence.

In view of this, the applicant amasss in being engaged in the experience of computor-keyboard research with production and marketing all the year round, and priority obtains the fact that multinomial patent is authorized by Taiwan Patent Office, then continue research, hope can be developed an element simple in structure and can be obtained to expect the key switch of effect, through experiment repeatedly, firstly appear and make the utility model " Computer key switch ".

The purpose of this utility model is to overcome the complex structure of existing computor-keyboard pushbotton, and during assembly fee, take a lot of work, the production cost height; Provide a kind of simple and reasonable, save time, saving of labor, Computer key switch that production cost is low.

The Computer key switch that the utility model proposes, comprising a keycap, it is a cap body, surround the key cover that quadrangle down extends from top underside, a key tube cylindraceous down extends from the top underside one in central authorities at the key cover, below key puts two places relative key cover, be one section cover that hollows out and lack, cover lack the place from above down extend a nest plate, the outstanding cover hook that forms at the end place; One key box, its size be corresponding to the key cover, down is recessed to form the box rank of the recessed and intersection of a box corresponding to the nearly central sections of two subtend inwalls of nest plate, and prominent to establish a box prominent in the central one on box rank; One conducting ring, by the annulated column of top down one extend a ring skirt, on the ring skirt central interior end face below the annulated column, establish conductive layer; Key box and conducting ring are many moulding of one; Add rib on the key box inwall.

Now the embodiment of concrete technology contents of the present utility model shown in conjunction with the accompanying drawings is further described.Wherein

Fig. 1: three-dimensional exploded view of the present utility model.

Fig. 2: profile after the combination of the present utility model.

The shown by reference numeral explanation:

Keycap 1 box recessed 21

Key overlaps 11 box rank 22

Key tube 12 boxes prominent 23

Cover lacks 13 conducting rings 3

Nest plate 14 annulated columns 31

Cover hook 15 ring skirts 32

Key box 2

As shown in the figure, basically, the utility model is combined by a kind of keycap 1, one a key box 2 and a conducting ring 3.

Wherein, keycap 1 is a cap body, down extends key cover 11 from top underside, and it surrounds square or rectangle, and a key tube 12 cylindraceous also extends from the top underside one in the central authorities of this key cover 11, and its purpose is for pushing the conducting ring 3 of narration in the back.Simultaneously, on the relative key cover 11 in two places, the below is one section cover that hollows out and lacks 13, and extends a nest plate 14 from the top, and the then outstanding cover hook 15 that forms in the lower end of this nest plate 14 is for hooking together the inwall of the key box 2 of narration in the back.

Key box 2 is and the one-body molded and vertical extent of finger-board that its size is corresponding to aforesaid key cover 11, so that fit.Corresponding to two subtend inwalls of nest plate 14, it is recessed 21 that nearly middle section down is recessed to form the thin box of a wall thickness, and form box rank 22 in intersection, the central authorities on these box rank 22, and it is prominent 23 then to extend the prominent box of establishing, and hooks together for aforementioned cover hook 15.

It is well-known for conducting ring 3, is to make with one-body molded mode full wafer, and the position is corresponding to key box 2, by the annulated column 31 of a top, the below one extends into a trumpet-shaped ring skirt 32, and the central top of ring skirt 32 is below annulated column 31, then has conductive layer (general knowledge is because of projection angle does not show).

Please consult Fig. 2 again, the utility model is in when combination, and key box 2 is to be nested on the conducting ring 3, and keycap 1 is linked on the box prominent 23, so bullet on unlikely.

When using, then push and down produce displacement, and key tube 12 bump annulated columns 31 and make its distortion, and the conductive layer of central interior touches the contact of below circuit board and form road from keycap 1, be key entry; When causing the stressed disappearance of keycap 1 when loosing one's grip, then its up resilience, cover hook 15 is promptly with limit till the box prominent 23, so the leeway of keycap 1 supreme bullet.

If increase frictional force is relaxed bullet speed and strength, it must add and put rib between the wall of key box 2, and this practice is well-known skill, so do not give unnecessary details.

Implement according to the utility model, because key box 2 is many one-shot formings of full wafer with conductive plate 3, so it can be once nested superimposed, and only need with keycap 1 one by one sunk key box 2 get final product, therefore, very little when institute takes a lot of work, this is incomparable by known Computer key switch.

What the utility model disclosed, just one of preferred embodiment, the change of every part or modification and come from technological thought of the present utility model and be the button that the people was easy to know by inference of haveing the knack of this skill are all within patent right scope of the present utility model.

In sum, no matter the utility model is with regard to purpose, and means and effect show that all itself and known technical characterictic are different, and its creation are not only reasonable and practical, and save time, saving of labor, saving product cost.
