Description

Key-press module

Technical field

The utility model is a kind of press-key structure, refers to a kind of novel structure of pair buttons at least that central pivot is provided with of exempting especially.

Background technology

Because the generally use of computer peripheral device, people use button to think that the occasion of switch has finding more, be one as keyboard, sometimes then be one key module tool two or above switch, special function keys as mouse is an example, and modal example is to be the volume operating key as mobile phone, is the use of two key switches.

This is the mode that two or above key switch are provided with the one key module, with respect to the occasion that is provided with one by one, but nature economization material and assembly cost, and even the space.And, for product design, can keep the integrality of outward appearance, therefore, be two or the setting of above key switch as modular manner how, real is the problem of dealer's concern.

With the mouse is example, existing key-press module is as shown in Figure 1, basically, is on a printed circuit board (PCB) A key-press module B to be set, and key-press module B as shown in Figure 2, be by a key base C, tool two is pressed key D and E on it, and the both sides central authorities of key base C, then open pivot hole F, and passed through by a pivot G, and it is therebetween ccontaining also to establish a pertusate pressure key H in addition, promptly forms key-press module as shown in Figure 3.

This mode no doubt can reach the assembling and the purpose of start, only disappearance be must tool pivot G setting, except increasing assembly, when passing through pivot hole F, also add to the difficulties, and its with the corresponding relation of circuit board A between, must tool one locate or depend on; And, the two side central authorities of key base C are added put pivot hole F, reduced the stress of material, can be rated as a fly in the ointment.

In view of this, the applicant is this in the experience of being engaged in periphery research and development of products of electronic product and information and production and marketing all the year round, concentrates on studies, and the phase can overcome above-mentioned disappearance, through testing repeatedly, firstly appears and makes " key-press module " of the present utility model.

The utility model content

The purpose of this utility model provides a kind of " key-press module ", in the hope of overcoming the defective of prior art.

A kind of key-press module, it comprises:

One keyseat, its central tool one keyhole, and prominent to establish two keys prominent, and each tool one of respectively prominent tool one jack of this key, and its outside is pressed prominent, and;

Key in one, its tool one size be greater than the middle sheet of keyhole, one side tool size less than keyhole by prominent, the then prominent key of establishing in of side is pressed prominent in addition;

Pass through keyhole so that the key of middle key is prominent, and jack can supply external binding, the formation of passing through two press prominent with one in key press three buttons of dashing forward.

Via enforcement of the present utility model, it can be exempted outside the meticulous puzzlement that brings assembling of existing member, the stress of the keyseat not existing sidewall of reason is bored a hole and is weakened, and can be rated as the good replacement scheme of key switch module, also is a quantum jump of three key switch modules.

Be further to disclose concrete technology contents of the present utility model, at first see also graphic, wherein:

Embodiment

As Fig. 4 and shown in Figure 6, basically, key-press module of the present utility model is by key 2 in the keyseat 1,, and cooperates a fixed head 3 being linked to circuit board 4, and can be fixed in a housing 5 and form.

Wherein, keyseat 1 is for slightly being strip, its central tool one keyhole 11 so that for after chat in the passing through of key 2, and in described keyhole 11 both sides, then each prominent key of establishing is prominent 12, and respectively opens a jack 13, so as for after the usefulness of fixed head 3 bindings chatted.The both sides of keyhole 11, then each projection has a fin 14, in addition, and the both sides of each key prominent 12, then tool is pressed prominent 15 setting, so that press switch 41 usefulness of a correspondence.

In key 2 be to be solid content, its central authorities be size greater than middle sheet 21, one sides of aforementioned keyhole 11 then is that size dashes forward 22 less than pressing of aforementioned keyhole 11, so that for the usefulness of pushing, and its side in addition, then in the tool one key press prominent 23 so that for the usefulness of pushing the switch 41 on the circuit board 4.

Fixed head 3 is to be strip, and its purpose is in the usefulness of confession with aforementioned keyseat 1 binding, and basically, it has two pins 31, its size is corresponding to aforesaid two jacks 13, so that for interting, and its two side ends, each tool one fixed leg 32 then, and open post hole 33, so as for and by the installing article.Circuit board 4, as shown in Figure 6, be to pass through passing of location via pin 42 for having three switches 41, the position of these three switches 41 after assembling, be to press prominent 23 corresponding to aforesaid pressure prominent 15 and middle key, push so that can be optionally, and when implementing, circuit board 4 is to be fixed in by within the housing 5, two end slot J as shown in Figure 4, think the location, and fixed head 3 can be linked to by on the fixed leg K in the installing thing housing 5 by fixed leg 32, that is as Figure 10 and shown in Figure 11.

Please consult Fig. 7, Fig. 8, Fig. 9 and Figure 11 again, the utility model is when install implementing, and keyseat 1 can place among the key base C set on the housing 5, among this key base C and have a fluting 51 that runs through this housing 5.This moment this keyseat 1 can fin 14 as fulcrum, and be resisted against by on the arc groove L of installing article, form the swing state of seesaw; Press prominently 15 simultaneously, key is prominent 12, jack 13, and in press prominent 23 all to be placed through within this housing 5 by fluting 51, make this pressures prominent 15, press in this and dash forward 23, all can a corresponding switch 41, promptly as shown in figure 11.In addition, when this circuit board 4 is planted by groove J, and after this fixed leg 32 is screwed together in fixed leg K, this jack 13 will be respectively this pin 31 and place, make this circuit board 4, keyseat 1 and in key 2 all be immobilizated on this housing 5, promptly as Figure 10, shown in Figure 11.See also Fig. 6, Fig. 7 and shown in Figure 8, wherein the aperture of this jack 13 is big than pin 31, makes that this pin 31 was able to carry out displacement when this pressure prominent 15 was pushed this corresponding switch 41 respectively in this jack 13.

See also Fig. 4, Fig. 6 and shown in Figure 9, in addition since the size of middle sheet 21 greater than keyhole 11, therefore when the user push key 2 in this by prominent 22 the time, key presses prominent 23 to be started the switch 41 of correspondence in this, and can be by coming off in this keyseat 1.In other words, two side pressures prominent 15 can be carried out pushing of selectivity function, that is as shown in figure 11, keyseat 1 can provide two switches 41, that is are positioned at the pushing of switch 41 at two ends, and middle key 2 is pushing for intermediate switch 41 then; So, see through the selectivity operation that keyseat 1 and middle key 2 promptly can be three switches 41.

What the utility model disclosed is preferred embodiment, and patent right category of the present utility model is not all taken off in Ju Bu change or modification and come from technical conceive of the present utility model and be easy to the person of knowing by inference by the people who has the knack of this skill such as.
