Description

The Computer key switch

The utility model belongs to computer realm, particularly the Computer key switch.

Computer today society be indispensable affairs instrument because it has the function of a large amount of storages and fast processing information, therefore, all replaced traditional manual work in a lot of fields.

The input of computerized information though many different instruments and mode are arranged, up to now, still is input as in the majorityly with keyboard, even therefore PC, keyboard also is that the standard of not replacing is equipped with, and traces it to its cause, and is because of following due to traditional typewriting operates.

The key switch of keyboard can roughly be divided into mechanical type and diaphragm type, owing to pursue the light, thin, short, little of product, thus be in the majority with diaphragm type and conductive rubber mode person, and have and replace mechanical trend gradually completely.The principle of diaphragm type is the contact through conductive rubber, touches the contact on the printing film circuit of below after pushing, as the input of instruction.

In fact, because the competition day by day of information products, and really not resembling main frame, key switch do not have upgrading on the function, so the product that people pursued is to see through the simplification of element, reduced the man-hour of assembling, and then reduce the cost of whole keyboard, thus improve the market competitiveness, be the developing direction of present stage and the condition of existence.

The purpose of this utility model is to provide a kind of element simple and can obtain the Computer key switch of expectation function.

The purpose of this utility model is achieved in that

Keycap by the cap of cap shape, inner down extend the Gai Zhu of a hollow from end face, and this Gai Zhu has four post wings of radial extension, and the interplane lid post lower edge of post, has opened short slot, and makes and form two subtends therebetween and be and have the outer post hook of opening barb;

The key frame is disposed and one-body molded according to key switch by plate body, and the upper ledge hole dimension of plate body top is slightly larger than the space of the post composition that the wing encloses that builds post, and between the wall of upper ledge hole inner plate body height, the one subtend is prominent establishes two frame tenons, and the lower frame hole of plate body below, its size is corresponding to conducting ring; Conducting ring has the conduction contact point; Conducting ring is arranged in the lower frame hole, and keycap penetrates the upper ledge hole via the embedding of lid post, and is hooked together in the frame tenon by the post hook, and when pressing down the keycap resilience, the post hook is limited by the frame tenon and is to go up bullet to end limit; The frame tenon can be four corresponding limits with the post hook and is provided with.

Via enforcement of the present utility model, it can obtain the simple assembling of element and be easy to outside the advantage, and especially keycap 1 all is formed in one with key frame 2, so on a large amount of production, can save many elements and man-hour.

Below in conjunction with accompanying drawing the technical solution of the utility model is further described.

Description of drawings:

Fig. 1: the three-dimensional exploded view of the utility model Computer key switch.

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

The figure number explanation:

Keycap 1 key frame 2 conducting rings 3 caps 11

The lid post 12 post wings 121 short slots 122 post hooks 123

Cabane 124 plate bodys 21 upper ledge holes 22 frame tenons 23

Lower frame hole 24

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

Wherein, keycap 1 is the cap body, and by the cap 11 of cap shape, the lid post 12 of a circular hollow is down extended from end face in inside, and this lid post 12 has the radial post wing 121 that stretches out some, and, opened short slot 122, and make and form one therebetween and have the outer post hook 123 of opening and having barb at lid post 12 lower edges of 121 on the post wing, and all elements of keycap 1, all be formed in one, build post 12 for strengthening, the columniform edge of a wing 124 must be amplified and form to the outer rim of its post wing 121.

It is on whole piece plate body 21 and to have a key switch position one-body molded for key frame 2, and square upper ledge hole 22 sizes that are positioned at plate body 21 tops are slightly larger than aforesaid lid post 12, and it can be set and slide; And plate body 21 height in upper ledge hole 22, then the prominent two frame tenons 23 of establishing of one subtend are that aforesaid post hook 123 up ending are limit when supplying to press down keycap 1 resilience, and the lower frame hole 24 below plate body 21, its size then corresponding after the conducting ring 3 chatted, make the conducting ring 3 can be therebetween ccontaining.

It is known substance for a conducting ring 3, precedingly addresses, and be to be contained in the lower frame hole 24, and when actual production, can be and cooperate keyboard and one-body molded, be provided with at corresponding each key switch place, these all belong to known technology, so do not give unnecessary details.

Please consult the constitutional diagram of Fig. 2 the utility model when reality is implemented again, when combination, conducting ring 3 places in the lower frame hole 24, keycap 1 then penetrates upper ledge hole 22 via the embedding of lid post 12, and hook together at frame tenon 23 by post hook 123, as shown in Figure 2, and the below of conducting ring 3 then is a known structure such as circuit board or thin film circuit and base plate etc.

When the utility model in when action, if knock keycap 1, then owing to stressed it is moved down, and make the root edge that cover post 12 press down conducting ring 3, and then be the connection of circuit, with the generation signal.And when application of force disappearance, then conducting ring 3 resiliences, and, make post hook 123 by frame tenon 23 hooks retaining by frame tenon 23 backstops, so do not cause keycap 1 to be deviate from by key frame 2.

Deviate from from key frame 2 for the location that makes keycap 1 is more stable and unlikely, the corresponding of post hook 123 and frame tenon 23 is provided with for many groups, all is provided with as four limits, and is not limited to two of subtend, and these all are the additional of similar elements, so also belong to equivalent scope.

What the utility model disclosed, just preferred embodiment is a kind of, the change of every part or modification and come from technological thought of the present utility model and be have the knack of this technical field the people was easy to know by inference, do not break away from patent right scope of the present utility model.
