Below, by specific instantiation explanation embodiments of the present invention, those skilled in the art can understand other advantages of the present invention and effect easily by the disclosed content of this instructions.The present invention can also be implemented or be applied by other different embodiment, and the every details in this instructions also can be based on different viewpoints and application, carries out various modifications or change not deviating under spirit of the present invention.It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.
As shown in Figures 1 and 2, the invention provides a kind of induction type contact making device 1, for supplying, be located at capacitance touch screen 2 surfaces, so that the assigned address on capacitance touch screen 2 surfaces is carried out to unartificial triggering; Wherein, described induction type contact making device 1 comprises: holder 11, fixture 12, conductive contact 13, be electrically connected to described conductive contact 13 and be also connected with capacitive device 14 switching device 15, be electrically connected to described switching device 15 and be connected with light or the driving circuit of color sensor 16 17.
Described holder 11, lower surface is provided with for the fixture 12 that is fixed to capacitance touch screen 2 surfaces; In one embodiment, described holder 11 in the form of sheets, described fixture 12 comprises: sucker, mechanical fixed support, stretching elastic ring or viscose etc., be fixed on described capacitance touch screen 2 by modes such as sucker absorption, stretching elastic ring colligation, viscose bonding by described induction type contact making device 1.
Described conductive contact 13, is located at described holder 11 lower surfaces and corresponding to described capacitance touch screen 2; At described induction type contact making device 1, by fixture 12, be fixed to the surface of described capacitance touch screen 2, make described conductive contact 13 corresponding to needing to realize the part of touch operation on capacitance touch screen 2, such as button etc.
And, as shown in Figure 2, in one embodiment, described switching device 15, capacitive device 14 and driving circuit 17 are located at the upper surface of described holder 11, preferably, position and described conductive contact 13 that switching device 15, capacitive device 14 and driving circuit 17 arrange are pros and cons, can reduce length of arrangement wire like this, reduce the impact of wiring wire on conductive contact 13 capacitance characteristics.
See also Fig. 3, in order to the mutual principle of work of electric signal between above-mentioned device to be described.
Described switching device 15, connect described conductive contact 13 and also connect described capacitive device 14, the conducting of described switching device 15 make described capacitive device 14 with conductive contact 13 conductings so that described conductive contact 13 with capacitance characteristic, thereby trigger described capacitance touch screen 2; The shutoff of described switching device 15 makes described capacitive device 14 and conductive contact 13 disconnect eliminating the capacitance characteristic of described conductive contact 13, preferably, capacitance when described conductive contact 13 has capacitance characteristic approaches the coupling capacitance of finger and 2 generations of trigger-type capacitance touch screen as far as possible, for example 3～5 pico farads, so touch capacitance touch screen 2 with simulation finger.
In one embodiment, described conductive contact 13 comprises: conduction sponge, conductive rubber, electric silica gel or conductive fabric; Because the capacitance of this conductive contact 13 self is almost nil, even if therefore keep normal contact condition also can not trigger capacitance touch screen 2 between conductive contact 13 and capacitance touch screen 2, and when switching device 15 conducting, can make this conductive contact 13 and capacitive device 14 conductings, thereby moment increases the capacitance of conductive contact 13, then triggers capacitance touch screen 2.
While being touched by object due to most of capacitance touch screen if this object with and faint coupling capacitance just can trigger screen, and the pin of most of electron device or the output capacitance of contact are all greater than human finger's coupling capacitance, therefore under the state that keeps often contacting with capacitance touch screen 2 at conductive contact 13, with electronics device simulation human finger capacitance characteristic, be difficult for, thereby the capacitance that has pin and conductive contact 13 to be directly connected once ordinary electronic device is difficult to accomplish directly to drive the mode of conductive contact 13 to trigger screen will to cause conductive contact 13 rises to approaching or is greater than human finger's capacitance false triggering touch-screen, ordinary electronic device must be realized between conductive contact 13 and capacitive device 14 switching device 14 of electrical isolation completely by can guarantee to turn-off time and indirectly drive conductive contact 13, described switching device 15 can be the device with mechanical switch plug-in strip, again or electromagnetic type relay etc.Described capacitive device 14 comprises: electric capacity or metal pad, for example little electric capacity (for example 3～5pf left and right) or larger metal pad or be directly connected with the power supply of circuit board or the metal pad on ground can, because the capacitance under above variety of way is all not less than human finger and touches touch-screen coupling capacitance, but can be comparatively approaching.
