Abstract
The utility model discloses a wire finder which includes a power supply, a probe, a signal detection amplifying and signal display circuit, and is characterized in that the signal detection amplifying and signal display circuit essentially consists of a GMOS hex inverter CD4069. The finder can quickly detect the wire break-points or hidden wire positions, can be used as an electroprobe or a screw driver, is compact and convenient in carrying, is widely applicable in electric equipment and electronic repair industries; the circuit of the product has simple structure, low manufacturing cost and can be produced in scale.
Description
Technical field
The utility model relates to a kind of electric wire finder.
Background technology
In the prior art, detect the position of electric wire breakpoint or concealed wiring, the product structure complexity of employing is used inconvenience, can not detect the position of electric wire breakpoint or hidden wiring efficiently.
Summary of the invention
Technical problem to be solved in the utility model is how a kind of electric wire finder is provided, and its line construction is simple, and low cost of manufacture can detect the position of electric wire breakpoint or hidden wiring rapidly.
The technical matters that the utility model proposed is to solve like this: construct a kind of electric wire finder, comprise power supply, probe, input amplification and signal display circuit, it is characterized in that described input is amplified and signal display circuit mainly is made of CMOS hex inverter CD4069.
The utility model can fast detect electric wire breakpoint or concealed wiring position, also can serve as electroprobe, change cutter usefulness, and is small and exquisite, easy to carry; can be widely used in electrician, electronic maintenance industry; this product circuit is simple in structure, and low cost of manufacture is produced on a large scale.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, 2, the utility model is mainly amplified by power supply, probe, input and signal display circuit is formed, and circuit mainly adopts a CMOS hex inverter CD4069, and wherein N3 and N4 formation frequency is the flutter generator about 1kHz; N1 and N2 are used for whether the 220V AC field exists in the detection sensor electric wire, and have processing concurrently and send faint ac voltage signal effect here from probe.Trivial oscillatory circuit can be opened or seal to the output terminal 4 pin current potentials height of N2.When popping one's head in away from AC field, 4 pin of N2 are output as electronegative potential, the D3 conducting, and oscillatory circuit stops, and at this moment 8 pin of N4 are electronegative potential, and T1 ends, and LED does not work.When probe shifted near AC field, 4 pin of N2 were high level, and at this moment D3 ends, oscillatory circuit unlatching work, and at this moment 8 pin of N4 are noble potential, the T1 conducting, LED is shinny, because flicker frequency is higher so when observing LED, present continuous luminance.According to the state of light emitting diode, just can judge the position of live wire breakpoint or concealed wiring in the maintenance.This product circuit is simple in structure, element heights is integrated, power saving, adopts the 3V button cell to make power supply, can make common electrical pen type profile.
