Description of the drawings
Fig. 1 is the circuit diagram of triode device for fast detecting.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, a kind of triode device for fast detecting, including not gate U1, resistance R3, electric capacity C1 and switch S1, institute
One end connection power supply VCC of switch S1 is stated, the other end for switching S1 connects the power end of not gate U6, the input connection of not gate U6

Operation principle of the present utility model is：Not gate U5, U6 and electric capacity C1 and resistance R3, R4 composition pulse square wave vibration
Device, frequency of oscillation can be selected between tens to hundreds of Hz.The output state of 2 points of a and b in circuit is always contrary.Test point
The base stage of test tube is treated in 1 connection all the time, when 2,3 two ends ends connect measured tube, due to the side of 2 points of difference output phase contrasts
Ripple signal, therefore light emitting diode D5, D6 alternating flashes.When a good NPN type triode is accessed at 2,3 two ends, in U1 points electricity
Under flat high, U2 level point low states, triode saturation conduction, D1 two ends are forced down in 1.8V, and D5 extinguishes；When U1 level points are low,
When U2 level points are high, triode cut-off, D5 is lighted, and D6 is back bias voltage due to what is added, is still extinguished.Thus judge, when " D5 goes out,
D6 is bright " when, show that measured tube is one have to manage and for NPN type pipe.In the same manner, when a good PNP type triode is accessed, it is then
D5 is bright, D6 goes out.
