Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1-6 of the present utility model shows a kind of mechanical keyboard for smart card.Wherein Fig. 1 is mechanical keyboard overall construction drawing.Fig. 2-Fig. 5 is respectively the structure chart of the young sheet button of pot, release liners, double coated film, partition and release film.
This mechanical keyboard comprises:
At least one pot of young sheet button 11, partition 12 and for the adhering layer 13 on the young sheet button of fixing pot 11 to partition 12.As shown in Figure 5, partition 12 offers the first through hole 121 for the young sheet button 11 of accommodating pot.The upper surface of the young sheet button 11 of pot and described partition 12 outstanding for the press section (namely after installation towards the one side of user) of finger presses.
Wherein adhering layer 13 can be double coated film, is described below for double coated film.
Double coated film 13 is laminated in partition 12 towards the one side of young sheet button 11 press section of pot and is provided with in the second through hole 131, second through hole 131 corresponding to sheet button 11 young with pot the fixed part 1311 be provided with for adhesion press section.Wherein, for ensureing that button has enough air bags, there to be good feel when using, the second through hole can divide into groups to arrange, and wherein at least two is one group, and hole adjacent in same group is communicated by air discharge duct.
Fixation portions 1311 realizes by putting up a bridge in the second through hole 131.Its concrete shape is preferably the roughly calabash shaped shown in Fig. 4, the mid portion of this fixed part 1311 is the structure of similar circle, the core of the young sheet button 11 of corresponding pot, this fixed part 1311 not only can the press section of the young sheet button 11 of adhesion pot like this, also for the input of user afterwards provides a position, touch point roughly, make the more convenient input of user.
Part outside the young sheet button 11 of the corresponding pot of double coated film 13 and the adhesion of partition 12 phase, young for pot sheet button 11 has just been fixed on partition 12 by such double coated film 13.
The young sheet button of pot can be circle, oval, cross or leg-of-mutton metal clips, shape as shown in figures 2 a and 2b.It there is firing point, the turn-on effect of shell fragment can be ensured.Number of keys sets according to visible card purposes, and from the young sheet of 1 pot to multiple pots of young sheets, consider card sizes scope and each module placement of card, button can take Parallel Symmetric to distribute.The size of the gold-plated Copper Foil contact on the flexible PCB of the size visual intelligent card of button sets.
Above-mentioned partition 12 is preferably identical with the quantity of pot son sheet button 11 with the quantity of the through hole on double coated film 13, and its shape is also roughly the same with the shape of pot son sheet button 11, and it is neglected greatly the size of the young sheet button 11 of pot and determines.The thickness of partition 12 is determined according to the height of the young sheet button 11 of pot.
For ensure button and flexible PCB follow-up can together be fixed on card substrate, this novel in double coated film 13 at least have a location hole 132 (two location holes have been shown in Fig. 4).The dimensional requirement of combined with intelligent card, preferably, the circular locating openings of this location hole to be diameter be 2.0 ± 0.1mm.
The equal toughness in two sides of double coated film, becomes easily infected by dust etc.For this reason, be laminated with release liners 14 in the one side of the young sheet button 11 of the pot dorsad of double coated film 13 during this is novel, this release liners 14 can select yellow release liners.This release liners 14 is not contaminated for the protection of double coated film, to ensure enough viscosity.For this reason, the outward appearance of release liners 14 is preferably identical with the outward appearance of double coated film 13, specifically as shown in Figure 3.
Before installation, the bottom surface of the young sheet button 11 of pot is easily scratched and pollutes, and for avoiding this situation, this novel keyboard also comprises the release film 15 being laminated in the young sheet button 11 of the pot one side relative with press section, specifically as shown in Figure 6.This release film 15 is preferably release polyethylene film.The viscosity of this release film 15 is determined according to the requirement of keyboard, micro-ly can glue or not glue.
When being installed on smart cards by mechanical keyboard afterwards, can directly tear release liners 14, allowing double coated film 13 directly contact with card matrix material, ensureing that button has certain stroke simultaneously, the tactile feedback of high-quality is provided to operator.Tear partition 12, release film 15 afterwards, button 11 is fixed in the key contacts of flexible PCB by bonding mode, make the young sheet button of pot by pressing and contact, realize conducting.
The design of the utility model mechanical keyboard should make the thickness of card at 0.76 ± 0.08mm, to meet the code requirement (Q/CUP 045-2012 code requirement) of China Unionpay's visual intelligent card.
Preferably, the thickness of mechanical keyboard is no more than 0.46mm, and the height of the young sheet button of pot is not higher than 0.25mm, and the peak of the young sheet keytop of pot should higher than card surface plane 0.1mm.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
