Accompanying drawing illustrates:
Fig. 1 is electrical block diagram of the present utility model.
In figure, 1 detection head.
Detailed description of the invention:
For the technical characterstic of this programme can be clearly described, below by detailed description of the invention, and combine its accompanying drawing,
The utility model is elaborated.
As shown in fig. 1, a kind of circuit breakpoint detection device, including a detection 1, detection 1 is by one
Resistance R1 is connected with the positive pole of a diode D1 and the negative pole of a diode D2 respectively, and diode D1's is negative
Pole is connected with 13 pins of a CD4069 chip, and the positive pole of diode D2 and 7 pins are connected, and 7 pins are again
Being connected with the negative pole of a button cell, 14 pins are connected with the positive pole of button cell by a switch S1, CD4069
12 pins of chip and 11 pins are connected, and the negative pole of 10 pins and a diode D3 is connected, diode D3
Positive pole be connected with CD4069 chip 9 pin, 9 pins pass sequentially through resistance R2 and resistance R3 and 5 pins
Being connected, resistance R2 is connected further through an electric capacity C1 and 6 pins, 6 pins and the base stage phase of an audion T1
Even, the colelctor electrode of audion T1 passes sequentially through a resistance R4 and a LED 1 and 14 pin phases
Even, the emitter stage of audion T1 is connected with the negative pole of button cell, 8 pins of CD4069 chip and 5 pins
It is connected.
Using circuit breakpoint of the present utility model to detect device, when detection 1 is away from AC field, 10 draw
Foot is output as low, and D3 turns on, and oscillating circuit is blocked, and now, 6 pins are electronegative potential, and T1 ends, LED1
The most luminous, thus can determine whether circuit no-voltage；When detection 1 is close to AC field, 10 pins are each
The positive half period of alternating current presents high potential, now D3 cut-off, and oscillating circuit works, and LED1 flashes.Thus
May determine that circuit is working properly.
Above-mentioned detailed description of the invention cannot function as the restriction to this utility model protection domain, leads for this technology
For the technical staff in territory, any alternate modification or the conversion of being made this utility model embodiment all fall
In protection domain of the present utility model.
This utility model does not describes part in detail, is the known technology of those skilled in the art of the present technique.
