Abstract
The utility model relates to a tool for electricians, particularly relates to a test pencil, and discloses a voltage value display test pencil, which comprises a test contact, a hand-touch electrode, a capacitor, a light emitting diode, a voltage extracting device and a voltage displaying device. One end of the capacitor is connected with the test contact while the other end is connected with the hand-touch electrode, and the capacitor is parallelly connected with the light emitting diode and the voltage extracting device. When the test contact contacts with an electrified to-be-tested power source, the voltage display test pencil not only has a light source indication mark, but also is provided with the voltage display device displaying electrified voltage value of the to-be-tested power source, thereby quantizing voltage of the to-be-tested power source and bringing convenience for detection personnel to perform the further operation safely, accurately and efficiently.
Description
Technical field
The utility model relates to a kind of electrician's instrument, particularly a kind of test pencil.
Background technology
Whether test pencil is a kind of electrician's instrument, be used in the test wires charged.At present, traditional test pencil is by a neon bulb being arranged in its handwriting, if neon bulb is luminous during test, illustrates that lead has electricity, perhaps is the live wire of path; Otherwise the lead no power then is described, perhaps is the zero line in the path.But because the brightness of neon bulb is less, do not see Chu by day or under the high light, thereby whether it is luminous to be difficult for resolution.This has brought a lot of inconvenience for operating personnel's work.
Summary of the invention
The purpose of this utility model provides a kind of magnitude of voltage and shows test pencil, replace light-dark discrimination to neon bulb with the mode of liquid crystal display, and circuit is simple, and is easy to use, safe and reliable, the detection efficiency height.
A kind of magnitude of voltage shows test pencil, comprise test contact, hand touched electrode, electric capacity, light emitting diode, this magnitude of voltage show test pencil also comprise the voltage subtraction device and with the voltage display device, electric capacity one end is connected with test contact, the other end is connected with the hand touched electrode, and electric capacity and light emitting diode, voltage subtraction device three are in parallel.
When test contact when charged power supply to be measured contacts, this voltage shows that test pencil not only has the sign of light source, also has the voltage display device to show the electrified voltage value of power supply to be measured simultaneously.Whether charged the judgement to power supply to be measured that this not only greatly facilitates the testing staff also for the testing staff provides voltage data accurately, quantized power source voltage to be measured, so that testing staff's safety, carry out next step operation accurately and efficiently.
Description of drawings
Fig. 1 is circuit theory diagrams
1---electric capacity
2---light emitting diode
Embodiment
As shown in Figure 1.Electric capacity and light emitting diode, voltage subtraction unit three are in parallel, and the other end is connected with the hand touched electrode.When the electroprobe head contacts with power supply to be measured, and the part of human body is when contacting with the hand touched electrode.If power supply to be measured is electrified body, lumination of light emitting diode not only then, simultaneously, the voltage subtraction unit proposes voltage swing accurately, and is transferred to the voltage display device, by voltage display device display voltage value.
Above-mentioned voltage display device preferably adopts LCD.
Although the utility model here specifically describes in conjunction with the specific embodiments, but be understandable that this is illustration rather than restriction, under the prerequisite of the spirit of the present invention that does not break away from accessory claim and limited, in the scope of and accompanying drawing disclosed at preamble, it all is possible reasonably changing and revising.
Claims (2)
1. a magnitude of voltage shows test pencil, comprise test contact, hand touched electrode, electric capacity, light emitting diode, it is characterized in that: this magnitude of voltage show test pencil also comprise the voltage subtraction device and with the voltage display device, electric capacity one end is connected with test contact, the other end is connected with the hand touched electrode, and electric capacity and light emitting diode, voltage subtraction device three are in parallel.
2. show test pencil as claims 1 described magnitude of voltage, it is characterized in that: described voltage display device adopts LCD.
