The right side of the partition board is provided with a printed circuit board. The electric tool can distinguish the positive pole and the negative pole of a crystal diode, and the type and the ebb and flow of a crystal triode. The electric tool can detect the on-off of a conductive wire and a transformer coil. The utility model has a plurality of functions, small size, and convenient carrying.
Description
The utility model belongs to a kind of electric power tool.
As everyone knows, the most frequently used instrument of electrical repair worker and radio amateur has electric torch, flaw detection test pencil, signal generator and multimeter etc., they are respectively by lighting circuit, flaw detection survey circuit, oscillatory circuit, testing circuit constitute, has different functions, but their performances are single, carry and use inconvenience.
The purpose of this utility model is that a kind of collection multiple technologies of design are one, and the electric power tool that volume is little, function is many, easy to carry, uses to be suitable for electrical repair worker and radio amateur.
The utility model is rectangle by one by box body and the shell formed of lid, and an end is the socket of giving prominence to, the other end is recessed measuring head, the signal accessory power outlet is housed on it, and lid one side is equipped with switch and two light emitting diodes, and the survey base is housed between the light emitting diode.On the test headstock battery reed is housed also.There is a dividing plate box body inside, and it is divided into left and right two parts with box body, and the left side is a battery case, and the battery case upper end has lamp socket, and spot light lamp bulb is housed in the lamp socket.The battery case lower end is the test headstock, on the seat U-shaped copper sheet and battery reed is arranged; The dividing plate right side is in order to install parts such as printed-wiring board (PWB), switch, signal accessory power outlet.There is a binding post at the box body middle part, and its upper and lower part has a screw respectively.
The utility model principle can be illustrated in conjunction with its circuit theory diagrams Fig. 2.
Its circuit is surveyed circuit (D) by flashlight lighting circuit (A), signal generating circuit (B) testing circuit (C) with flaw detection and is formed.
Signal generating circuit (B) is actually a unijunction transistor relaxation oscillations circuit.When detecting transistor with testing circuit (C), resistance R
6, R
7Bias voltage is provided for respectively tested NPN pipe and PNP pipe.The triode conducting, LED
1Luminous, can differentiate kind, polarity and the quality of tested transistor in conjunction with the bis of surveying base.According to the unidirectional conducting principle of crystal diode, in conjunction with LED
1Whether luminous, the quality of distinguishable crystal diode and polarity detect the break-make of lead and transformer coil simultaneously.Discharge and recharge the principle that makes circuit moment conducting according to electrolytic condenser, in conjunction with LED
1Luminous situation, the quality of resolution electrolytic condenser.
Between signal generating circuit (B) and testing circuit (C), connect resistance R
5With diode D, its effect is, when signal generating circuit (B) is worked, and LED
1Luminous double as work indication when preventing that simultaneously testing circuit (C) from detecting lead, seals in the signal generating circuit (B) electricity, causes non-power consumption.
Flaw detection is surveyed in the circuit (D), triode BG
1Play the switch amplification of holding concurrently, when gauge head is sensed electric signal, BG
1Conducting is simultaneously with triode BG
2, BG
3Together electric signal is amplified, at this moment LED
2Luminous, according to LED
2Whether luminously can conclude whether sense electric signal, playing the effect that electricity is surveyed in flaw detection.
The utility model is owing to be equipped with lighting circuit, flaw detection survey circuit, signal generating circuit and testing circuit, the type of not only distinguishable crystal diode both positive and negative polarity, transistor and quality, have the function that detects lead and transformer coil break-make simultaneously, and can detect the quality of electrolytic condenser and the quality of signal generator.So it has the many advantages of function, and volume is little, carries and use equal facility.
