The progress of press-key structure 100 provided by the utility model compared with the existing technology is:
One layer of flexible glue layer 3 is arranged in the utility model on the circuit card 1, and one layer of pressing plate 4 is arranged on flexible glue layer 3, soft
Glue-line 3 can cover each key contacts 11, and pressing plate 4 is equipped with the pressing area for pressing and indicating each key contacts 11
41, the operation of press-key structure 100 is transferred to flexible glue layer 3 by the pressing of pressing area 41 and is transferred to key contacts 11, flexible glue layer 3
It can prevent dust and moisture etc. from entering key contacts 11, when assembly only needs successively populated circuit board 1, flexible glue layer 3 and pressing plate
4, operation difficulty is reduced, the pressing area 41 in pressing plate 4 provides space for the pattern of design instruction key contacts 11, favorably
In the external appearance for improving press-key structure 100.
1 is please referred to, press-key structure 100 further includes in the protection cap 2 between circuit board 1 and flexible glue layer 3, protection cap 2
Corresponding each key contacts 11 are equipped with through-hole 21, pressing in the through-hole 21 and through-hole 21 on flexible glue layer 3 while covering protection lid 2
Key contact 11.
Formed there are four key contacts 11 on circuit board 1 in the press-key structure 100 of the present embodiment, in protection cap 2 four it is logical
For the exposing of key contacts 11, flexible glue layer 3 is strip in hole 21, four through-holes 21 on 3 covering protection lid 2 of flexible glue layer and logical
Key contacts 11 in hole 21.In the present embodiment, silica gel may be selected in the material of flexible glue layer 3.Silica gel this kind material itself has
There is good fire resistance characteristic, can prevent moisture or dust etc. from entering in through-hole 21 and influencing key contacts 11.
In other embodiments, the quantity of key contacts 11 and arrangement can also otherwise, and flexible glue layer 3 is according to pressing
The form of bond structure 100 is arranged, as long as key contacts 11 can be covered.
Fig. 1 and Fig. 2 are please referred to, the outside of through-hole 21 is equipped with arc-shaped flange 22, the interior table of flexible glue layer 3 in protection cap 2
Face is concavity, and both ends are equipped with the chimb 31 engaged with flange 22, so that flexible glue layer 3 can be fastened in protection cap 2.
Referring to Fig. 1, pressing plate 4 is set there are four pressing area 41, each pressing area 41 includes corresponding each key contacts 11
Pressing ontology 411, and the cantilever 412 being connect for ontology 411 will to be pressed with pressing plate 4.In the present embodiment, this is pressed
Body 411 is generally round, and the quantity of cantilever 412 is two, can reduce the manufacture difficulty of pressing plate 4 in this way and be sufficient for making
With requiring.By setting cantilever 412 connection between pressing ontology 411 and pressing plate 4, pressing ontology 411 is being pressed
Certain displacement or degree of deformation are obtained under power.Preferably, at least part of cantilever 412 is curvilinear, in pressing ontology 411
Surrounding is surround, and can increase the length of cantilever 412 in this way, to increase the amount or deformable that pressing ontology 411 can be subjected to displacement
Degree, also, two cantilevers 412 about pressing ontology 411 the center of circle be arranged with being centrosymmetric, to pressing ontology 411 apply
When power, more evenly it can move downward or deform, guarantee the stability of press-key structure 100, in appearance also with more symmetrical
Beauty.
It is understood that pressing ontology 411 or other shapes, such as rectangular, oval, polygon.Cantilever
412 quantity can also can also connect in other ways pressing ontology 411 and pressing plate 4 for other quantity, cantilever 412, such as
Cantilever 412 is that connection presses ontology 411 and pressing plate 4 deviously in the outer space of pressing plate 4, as long as to press ontology
411 can be pressed downwardly under force flexible glue layer 3 and further be urged to key contacts 11.
Setting in this way, user is to the first force since to pressing ontology 411 of the operation of press-key structure 100,
Pressing 411 stress of ontology is moved down or is deformed, and being urged to flexible glue layer 3 makes flexible glue layer 3 deformation occurs, and then flexible glue layer 3 is oppressed
To key contacts 11, which is that elasticity presses and the stroke pressed is longer, and makes pressing lighter by cantilever 412
It is sensitive, be conducive to the pressing experience for improving user.
Further, due to flexible glue layer 3 it is depressed can deformation occurs, pressing plate 4 can be closely pressed together on the flexible glue
On layer 3, even if the pressing area 41 in the present embodiment has the engraved structure connecting with the external world, moisture and dust etc. can be also prevented
It slides through pressing area 41 to 3 other positions of flexible glue layer.
In order to further indicate the function of the corresponding key contacts 11 of each pressing area 41, the present embodiment is also in pressing plate 4
It is upper to be provided with marking keys 5.As shown in fig. 1, each pressing area 41 is equipped with a marking keys 5.Marking keys 5 include mark
Ontology 51 and the suspension column 52 for being connected to mark ontology 51, pressing ontology 411 are equipped with mounting hole 413, pass through suspension column 52 and peace
It fills hole 413 and corresponds installation, marking keys 5 can be mounted in pressing plate 4.In the present embodiment, marking keys 5 and pressing
To be fixedly connected between plate 4, suspension column 52 is fixedly mounted in mounting hole 413 by modes such as gluing or welding.In other realities
It applies in example, is detachably connected between marking keys 5 and pressing plate 4, such as suspension column 52 is directly inserted into mounting hole
413, the interest of press-key structure 100 and easy disassembly can be increased in this way.
