Abstract
The utility model discloses a one-body touch keypad which comprises a PC touch keypad and a touch circuit board disposed on the bottom of the PC touch keypad. The PC touch keypad is provided with touch buttons that correspond to touch control buttons of the touch circuit board. A sealing glue frame equipped with an accommodating chamber is arranged on the bottom of the PC touch keypad. The touch circuit board is disposed inside the accommodating chamber. A one-body assembly structure is adopted by the touch keypad to package the touch circuit board with a non-conductive material for manufacturing the PC touch keypad through epoxy resin, thereby greatly improving the overall stability and substantially improving touch control sensitivity of connection between the PC touch keypad and the touch circuit board while satisfying a requirement for thickness. The one-body touch keypad has a simple structure and is highly practical.
Description
Technical field
The utility model relates to a kind of integral type touch key-press plate.
Background technology
At present; Existing touch-key panel adopts electrical insulator materials such as PMMA (polymethyl methacrylate), PC engineering plastics, marble usually; Requiring material thickness to be not more than 8mm, is to increase its thickness through between touch pad and base plate, dosing conductive sponge, is generally touch pad, base plate and conductive sponge and adopts knockdown in the majority; But its touch sensitivity of often bigger thickness effect, and outward appearance is heavy.
Summary of the invention
To the deficiency that prior art exists, the utility model technical problem to be solved is, provides a kind of simple in structure, with low cost, guarantees effectively to improve the integral type touch key-press plate of its touch sensitivity under its normal prerequisite of using satisfying thickness requirement.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of integral type touch key-press plate; Comprise PC touch key-press plate and be located at the touch circuit board of PC touch key-press plate bottom; Said PC touch key-press plate is provided with and the corresponding touch key-press of touch-control button that touches circuit board, and said PC touch key-press plate bottom also is provided with the sealing skeleton with containing cavity, and said touch circuit board is packaged in this containing cavity.
Above-mentioned integral type touch key-press plate, said touch circuit board is fixed in the containing cavity through epoxy encapsulation.
The advantage of the utility model integral type touch key-press plate is: adopt the integral type package assembly; To touch circuit board through epoxy resin and be packaged in one with the non-conducting material of making PC touch key-press plate; Improved whole stability greatly, and when satisfying thickness requirement, improved greatly PC touch key-press plate with touch circuit board be connected touch-control sensitivity; The utility model is simple in structure, and is practical.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the workflow diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details;
Like Fig. 1, shown in 2; A kind of integral type touch key-press plate; Comprise PC touch key-press plate 1 and be located at the touch circuit board 2 of PC touch key-press plate 1 bottom; On PC touch key-press plate 1, be provided with the touch key-press 11 corresponding, the sealing skeleton 3 with containing cavity 31 also be set, touch circuit board 2 and be packaged in this containing cavity 31 in the bottom of PC touch key-press plate 1 with the touch-control button that touches circuit board 2 21.Touching circuit board 2 is fixed in the containing cavity 31 through epoxy resin 4 encapsulation.
The course of work of the utility model is: directly be the touch-control chip causes input capacitance through the touch of human finger variation; The reference capacitance of input capacitance and built-in chip type is relatively exported differential signal; Obtain high-low level at output after sending out big by amplifying circuit again, can realize control analog signal.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection range of the utility model.
Claims (2)
