Description

Ultra-thin formula touch keyboard

Technical field

The utility model relates to a kind of keyboard, especially a kind of ultra-thin formula touch keyboard.

Background technology

Present keyboard is all more thick and heavy, the mfg. moulding die more complicated.In the mechanical process of frequency key pressing, thereby the keyboard leather cup occurs easily wearing out, breaks and reduced the life-span of keyboard.It is single that present keyboard exists form, and volume is bigger, thick, serviceable life short, clean and carry inconvenient problem, in addition because existing keyboard adopts hard material to make mostly, in case moulding, just immutable its profile.

The utility model content

At the weak point that exists in the above-mentioned technology, the utility model provides a kind of flexibility good, simple in structure, with low cost, and its integral thickness can reach a kind of ultra-thin formula touch keyboard of 0.4mm.

For achieving the above object, the utility model provides a kind of ultra-thin formula touch keyboard, last conductive substrate, insulation course and following conductive substrate by stack successively constitute, conductive substrate and the described inner surface of conductive substrate down are provided with conductive coating on described, the edge of described conductive coating also is printed with conductive silver paste, described conductive silver paste is connected with processor, and described surface of insulating layer is distributed with a plurality of key holes and air channel.

Described upward conductive substrate and the described quantity of conductive silver paste described in the conductive substrate down are two, and are arranged at described conductive substrate and the described edge of conductive substrate both sides down gone up respectively.

Described two described conductive silver pastes going up in the conductive substrate form Y+, Y-electrode, and two described conductive silver pastes in the described conductive substrate down form X+, X-electrode.

Described Y+, Y-electrode and described X+, X-electrode form an equivalent resistance.

Described air channel is arranged between two adjacent described key holes, and is connected with described key hole.

Compared with prior art, the utlity model has following advantage:

The ultra-thin formula touch keyboard that the utility model provides, last conductive substrate, insulation course and following conductive substrate by stack successively constitute, inner surface at last conductive substrate and following conductive substrate is provided with conductive coating, the edge of conductive coating also is printed with conductive silver paste, conductive silver paste is connected with processor, surface of insulating layer is distributed with a plurality of key holes and air channel, two conductive silver pastes in the last conductive substrate form Y+, Y-electrode, two conductive silver pastes in the following conductive substrate form X+, X-electrode, wherein, Y+, Y-electrode and X+, X-electrode form an equivalent resistance.The utility model is simple in structure, and is with low cost, and its general thickness can reach 0.4mm, even thinner, because therefore its whole concrete good softness can also carry out convolution with integral body, is more convenient for carrying and depositing.

Embodiment

For clearer statement the utility model, the utility model will be further described below in conjunction with accompanying drawing.

As Fig. 1 and shown in Figure 2, the utility model provides a kind of ultra-thin formula touch keyboard, last conductive substrate 1, insulation course 2 by stack successively constitute with following conductive substrate 3, inner surface at last conductive substrate 1 and following conductive substrate 3 is provided with conductive coating 5, edge at conductive coating 5 also is printed with conductive silver paste 4, and conductive silver paste is connected with processor (not describing among the figure).In last conductive substrate 1 and following conductive substrate 3, the quantity of conductive silver paste 4 is two, and is arranged at described conductive substrate and the described edge of conductive substrate both sides down gone up respectively.Two conductive silver pastes in the last conductive substrate form Y+, Y-electrode, and two conductive silver pastes in the following conductive substrate form X+, X-electrode, and Y+, Y-electrode and X+, X-electrode form an equivalent resistance.Insulation course 2 surface distributed have a plurality of key holes 6 and air channel 7, and air channel 7 is arranged between two adjacent key holes 6, and are connected with adjacent two key holes.

Upper and lower two conductive substrates organically combine into an integral body with the insulation course of centre, when finger presses is above key hole, last conductive substrate is because of stressed flexural deformation, conductive layer is connected the conductive layer of conductive substrate down, this moment is equivalent resistance of formation between finger presses point and X+, X-, Y+, Y-, processor compares the equivalent resistance of directions X and the equivalent resistance of Y direction more separately, draw the coordinate figure of press points then by the A/D conversion, again coordinate is delivered to CPU and handle, realize keypress function.

More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
