Detailed description of the invention
As shown in Fig. 3,4,5, this utility model anti-silver ion diffusion water proof and dust proof touch-switch includes pedestal 1, fastener terminal 2, shell fragment 3, stickers 4, collision mat 5, button 6, cover plate 7, described pedestal 1 down caves in from upper surface 11 and is formed with accommodating die cavity 12, and described pedestal upper surface 11 is up extended with a circle isolation flange 13 around described accommodating die cavity 12 upper end, described pedestal upper surface 11 is the most up extended with guide pillar 14；Described fastener terminal 2 includes being placed in the middle bubble point 21 that described pedestal houses in die cavity 12 and the both sides bubble point 22 being positioned at described middle bubble point 21 both sides, also include stretching out in the PIN 23 outside described pedestal 1, between described middle bubble point 21 and both sides bubble point 22, be provided with blocking-up groove 24；In described shell fragment 3 is placed in described accommodating die cavity 12 and be positioned at above described both sides bubble point 22；Described stickers 4 covers described accommodating die cavity 12 and is connected with described pedestal upper surface 11, and described collision mat 5 bottom surface is connected to described stickers 4；Described button 6 includes that base 61, the press section 62 up extended in the middle of the base 61, lower end stretch out in the contact 63 of base 61 lower end；Described cover plate 7 is provided with intermediate throughholes 71 and the positioning through hole 72 passed for the guide pillar 14 on described pedestal 1, described cover plate 7 is arranged at above described collision mat 5, upper end, described button press portion 62 up stretches out in outside cover plate 7 intermediate throughholes 71, and the guide pillar 14 on described pedestal 1 penetrates in the positioning through hole 72 of cover plate 7.
Described shell fragment 3 is placed on the both sides bubble point 22 that pedestal houses in die cavity 12, down pressing button 6, and the contact 63 of button 6 down pushes shrapnel 3, presses and contacts with centre bubble point 21, form a path under the center stressed of shell fragment 3；Loosening by power, shell fragment 3 back to nature form, the middle bubble point 21 in accommodating die cavity 12 disconnects with both sides bubble point 22, completes the effect of switch.
As mentioned above, because the setting of isolation flange 13, described stickers 4 covers described accommodating die cavity 12 and its periphery lower end is connected to pedestal upper surface 11, so that described accommodating die cavity 12 is formed as sealing cavity, avoid the sulfide in the external world, moist aqueous vapor etc. that fastener terminal 2 and shell fragment 3 produce oxidation and silver ion diffusion phenomenon, reach the effect of silver ion diffusion dust-proof, waterproof, anti-, meet GB 4208-2008 shell protection grade IP68 level requirement；In addition, because the electromagnetic field produced after groove 24 can prevent plastic cement moisture absorption further or make moist that blocks in the middle of fastener terminal between bubble point 21 and both sides bubble point 22 causes silver ion diffusion, so, not only ensure that the effectiveness of this utility model touch-switch, moreover it is possible to effectively extend the service life of this utility model touch-switch.
In the present embodiment, it is also preferred that the left the height of described isolation flange 13 is 0.01mm-0.3mm.
In the present embodiment, it is also preferred that the left described pedestal upper surface 11 is up extended with projection 15 from corner, between described projection 15 and isolation flange 13, there is gap.Specifically, pedestal upper surface 11 part between described projection 15 and isolation flange 13 and between projection 15 and projection 15 is just pasted for stickers 4, thus the when of installing stickers 4, collision mat 5, puts into according to this position, so, stickers 4, the location of collision mat 5 are greatly facilitated.
Described guide pillar 14 is also formed in 11 4 jiaos, pedestal upper surface.
When assembling cover plate 7 with pedestal 1, the guide pillar 14 that the positioning through hole 72 of cover plate 7 is directed at pedestal 1 is loaded, then use high temperature hot pressing to be suppressed by guide pillar 14 and be shaped to riveting point.It is also preferred that the left described cover plate 7 down caves in the position of corner is formed with step 73, described positioning through hole 72 is disposed through on this step 73, so, when rivet hot guide pillar 14, will not impact button 6.
As shown in Figure 6, the intermediate throughholes 71 of described cover plate 7 includes the first sector hole 711 of lower end and the second sector hole 712 of upper end, the diameter of described first sector hole 711 is more than the second sector hole 712, thus two sector holes are formed as step, when assembling with button 6, described base 61 is placed in described first sector hole 711, and upper end, described press section 62 up stretches out in outside the second sector hole 712.The setting of step two sector hole so that cover plate 7 can more effectively peg button base 61, navigation button 6 axially-movable, thus prevent button 6 from coming off or tilting.
During it is also preferred that the left make pedestal 1, use the mode of injection, pedestal 1 is molded into fastener terminal 2 together with, thus described pedestal 1 is integrally formed with fastener terminal 2, adopts and makes water resistance of the present utility model more preferable in this way.In the present embodiment, the high-temperature nylon (such as PPA or HTN or the plastic material such as PPS or PA9T or LCP) that described pedestal 1 uses water absorption rate extremely low is made, thus reduces the possibility that pedestal 1 makes moist further, reduces the probability of sliver diffusion the most further.
It is also preferred that the left as it is shown in fig. 7, described fastener terminal 2 uses connecting type punching press, reel is packed, be easy to continuous electroplating, be molded and cut molding, thus can effectively raising efficiency, save artificial, described fastener terminal 2 can be fabricated to four feet or the product of bipod PIN as required.
In the present embodiment, it is also preferred that the left described collision mat 5 uses silica gel, described stickers 4 to use PET or PI mucosa part.When specifically producing, silica gel treatment device is first used to be passivated by Silica Surface, then using viscosity auxiliary agent to be sticked together with stickers 4 by collision mat 5, PET or PI mucosa two sides is all with viscosity auxiliary agent, and the another side after bonding with silica gel is then directly bonded on pedestal upper surface 11.In other embodiments, described collision mat 5 and stickers 4 may be used without other materials with said function and make.
During above-mentioned orientation describes, using the orientation up and down of Fig. 4 as reference.
