Abstract
The utility model relates to a frock use complicacy is fixed a position in order to solve to keyboard, purpose when keyboard button commonly used is at present put into production, and the short problem of life. The utility model provides a novel keyboard press -key structure, the keyboard is formed by connecting a plurality of buttons, the button includes presses key cap and conductive silicone, press and adopt tight interference fit structure between key cap internal diameter and the conductive silicone external diameter, the back that completes, the clearance of pressing between key cap internal diameter and the conductive silicone external diameter is zero. The utility model is suitable for a keyboard button.
Description
Technical field
The utility model relates to keyboard, particularly the button of keyboard.
Background technology
Nowadays common on the market townhouse button usually adopts plastic cement to add the structure of silica gel, technology mode takes button cap to paste conducting resinl surface mostly, or increase plastics or hardware bracket as fixing, need during production to drop into a large amount of positioning tool, automation attaching apparatus etc., complex process, cost is higher.Further, is that bonding method carries out connections button cap and electric silica gel due to what adopt, paste material over time used use after easily aging with come off, affect the useful life of keyboard.
Utility model content
The utility model uses complicated for keyboard conventional at present positioning tool when producing, and the problem that useful life is short, a kind of novel keyboard press-key structure is provided, keyboard is formed by connecting by some buttons, described button comprises button cap and electric silica gel, it is characterized in that, adopts tight over-surplus fit structure between described button cap internal diameter and electric silica gel external diameter, after completing, the gap between button cap internal diameter and electric silica gel external diameter is zero.
Particularly, be provided with the brace rod for controlling gap between button cap and electric silica gel in described button cap, when button pressed, the interstice coverage between button cap and electric silica gel substrate is 0.3mm to 0.7mm.
A kind of preferred scheme is that, when button pressed, the gap between button cap and electric silica gel substrate is 0.5mm.
Increasing the object of brace rod is cause card key to prevent from being unlikely to when button pressed stroke excessive.
Particularly, the two ends of described electric silica gel are provided with draw-in groove, and the inside of button cap is provided with snap fit, and described draw-in groove and snap fit match.
Particularly, described button cap is plastic key cap.
The beneficial effects of the utility model are: the townhouse key assembling mode of small size simplifies by the utility model greatly, achieves the free sticky subsides of button, is beneficial to production in enormous quantities, and effectively can control product cost.Owing to not using adhesive preparation, while raising button useful life, decrease environmental pollution.
Embodiment below in conjunction with embodiment is described in further detail the technical solution of the utility model; should be noted that; embodiment is only used to help reader to understand technical conceive of the present utility model and technology realization better, not in order to limit protection range of the present utility model.Every simple deformation of doing in technical foundation of the present utility model and its technical spirit technical scheme identical with the utility model all belong to the protection range of the utility model claim.
Accompanying drawing explanation
Fig. 1 is press-key structure schematic diagram of the present utility model.
Wherein, 1 is button cap, and 2 is electric silica gel, and 3 is the gap between button cap and electric silica gel.
Embodiment
The utility model uses complicated for keyboard conventional at present positioning tool when producing, and the problem that useful life is short, a kind of novel keyboard press-key structure is provided, as shown in Figure 1, keyboard is formed by connecting by some buttons, and described button comprises button cap 1 and electric silica gel 2, adopts the structure of tight interference fit between described button cap 1 internal diameter and electric silica gel 2 external diameter, after completing, the gap 3 between button cap internal diameter and electric silica gel external diameter is zero.
Embodiment
Keyboard is generally all formed by connecting by several key combination, and according to embody rule environment, the number of button can be different, generally all connected by circuit board between button.Button generally all comprises button cap 1 and electric silica gel 2, and during use, pressing keys, electric silica gel 2 triggering signal, signal is performed corresponding operation by control appliance after corresponding processor receiving and analyzing.Traditional button cap 1 is generally all connected by bonding method with electric silica gel 2, or increases plastics or hardware bracket as fixing, and need during production to drop into a large amount of positioning tool, automation attaching apparatus etc., complex process, cost is higher.Further, is that bonding method carries out connections button cap 1 and electric silica gel 2 due to what adopt, paste material over time used use after easily aging with come off, affect the useful life of keyboard.
The utility model, for Problems existing in existing button assembling process, proposes a kind of novel press-key structure, mainly improves case structure in the following aspects:
1, by the interference fit of plastic key cap 1 internal diameter and electric silica gel 2 external diameter, guarantee it and upper casing is assembled time Z-direction can not come off easily, Z-direction is key press direction.After completing, the gap 3 between button cap and electric silica gel is zero.
2, plastic key cap 1 is spacing respectively by a word position of bone of X-direction and Y-direction with electric silica gel 2, when button cap 1 oblique 45 degree press time, the elastic force of electric silica gel 2 impels it to reset, with this guarantee to assemble between button and button smooth, without drop.Particularly, a word position of bone is spacing to be realized by arranging draw-in groove at the two ends of electric silica gel 2, correspondingly, is provided with the snap fit matched with draw-in groove in the inner side of button cap 1.
3, plastic key cap 1 increases brace rod, limits the gap between itself and electric silica gel 2 substrate, is unlikely to stroke excessive and cause card key when button pressed.When button pressed, the interstice coverage between button cap 1 and electric silica gel 2 substrate is 0.3mm to 0.7mm, and one preferably gap width is 0.5mm.
Claims (5)
1. keyboard press button structure, keyboard is formed by connecting by some buttons, and described button comprises button cap and electric silica gel, it is characterized in that, adopt over-surplus fit structure between described button cap internal diameter and electric silica gel external diameter, after completing, the gap between button cap internal diameter and electric silica gel external diameter is zero.
2. keyboard press button structure as claimed in claim 1, it is characterized in that, be provided with the brace rod for controlling gap between button cap and electric silica gel in described button cap, when button pressed, the interstice coverage between button cap and electric silica gel substrate is 0.3mm to 0.7mm.
3. keyboard press button structure as claimed in claim 2, it is characterized in that, when button pressed, the gap between button cap and electric silica gel substrate is 0.5mm.
4. the keyboard press button structure as described in claim 1 or 2 or 3, it is characterized in that, the two ends of described electric silica gel are provided with draw-in groove, and the inside of button cap is provided with snap fit, and described draw-in groove and snap fit match.
