Abstract
The utility model provides an electroprobe, including test contact and grab handle, be provided with testing arrangement in the grab handle, testing arrangement includes current -limiting resistor, the neon tube, metal spring and hand touch electrode, still include alarm device and lighting device, alarm device includes resistance, the voltmeter, electromagnetic shaker and safe hand touch electrode, the contact, voltmeter and safe hand touch electrode are established ties, electromagnetic shaker and voltmeter are connected, lighting device is including illumination box and switch, be provided with light and power in the illumination box, the switch, light and power series. The utility model relates to an ingenious, whether electrified, can read out the magnitude of voltage moreover if can not only measure the measured object, but the magnitude of voltage that user's direct readout was surveyed, and when voltage was higher than safe voltage, the electromagnetic shaker vibrations reminded the tester dangerous to set up lighting device on electroprobe, also can work convenient to use than under the crape ring border.
Description
Technical field
This utility model relates to power test technical field, particularly relates to a kind of voltage test pencil.
Background technology
Voltage test pencil is also test pencil, is called for short " electroprobe ".It is a kind of electrician tool, whether charged for testing in electric wire.Handwriting has a neon bulb, if neon bulb is luminous during test, illustrates that wire has electricity or the live wire for path.At present, known voltage test pencil structure is to be in series by test contact, current-limiting resistance, neon tube, metal spring and hands touched electrode.Test contact is contacted with measured object, human contact's hands touched electrode, when measured object has high voltage relative to the earth, neon tube starter, represent that measured object is charged.But, the metal shell of a lot of electrical equipment is without to the adventurous electric shock voltage of human body, only representing that distribution capacity or normal resistance sensing produce electromotive force, make neon tube starter.General voltage test pencil cannot distinguish between adventurous electric shock voltage and non-hazardous induced potential, causes difficulty to detection electric leakage, it is easy to cause misjudgment, and uses difficulty under dark working environment, brings difficulty to test.
Summary of the invention
In order to overcome existing voltage test pencil to cannot distinguish between adventurous electric shock voltage and the deficiency of non-hazardous induced potential, this utility model provides a kind of voltage test pencil, whether this voltage test pencil can not only measure measured object charged, and energy read-out voltage value, user can directly read tested magnitude of voltage, thus judging whether danger, and illuminator being set on voltage test pencil, can also work under relatively dark situation.
Technical solutions of the utility model
A kind of voltage test pencil, including test contact and lever, test device it is provided with in lever, test device includes current-limiting resistance, neon tube, metal spring and hands touched electrode, described a kind of voltage test pencil also includes alarm device and illuminator, described alarm device includes resistance, voltmeter, electromagnetic shaker and safety hand touched electrode, contact, voltmeter and the series connection of safety hand touched electrode, electromagnetic shaker and voltmeter connect, described illuminator includes illumination box and switch, illuminating lamp and power supply, switch, illuminating lamp and power sources in series it is provided with in illumination box.
Described lever includes holding post and bottom plug, holds post and bottom plug and is connected by the mode of screw thread.
Described holding is provided with observation port on post.
Described holding is provided with drawing box in post, be provided with two containers in drawing box, places test device and alarm device respectively.
Described drawing box and bottom plug connect.
Described electromagnetic shaker and safe tentacle electrode connect.
Described lever is provided with finger grip district.
The beneficial effects of the utility model
This utility model design is ingenious, measured object can not only be measured whether charged, and energy read-out voltage value, user can directly read tested magnitude of voltage, and when voltage is higher than safe voltage, electromagnetic shaker shakes, remind tester dangerous, and illuminator is set on voltage test pencil, can also work under relatively dark situation, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model drawing box structural representation.
Fig. 3 is this utility model metal spring junction structural representation.
Detailed description of the invention
nullSuch as Fig. 1、Shown in 2 and 3，A kind of voltage test pencil，Including test contact 1 and lever，Test device it is provided with in lever，Test device includes current-limiting resistance 2、Neon tube 3、Metal spring 4 and hands touched electrode 5，A kind of voltage test pencil also includes alarm device and illuminator，Alarm device includes resistance 6、Voltmeter 7、Electromagnetic shaker 8 and safety hand touched electrode 9，Contact 6、Voltmeter 7 and safety hand touched electrode 9 are connected，Electromagnetic shaker 8 and voltmeter 7 connect，Illuminator includes illumination box 9 and switch 10，Illuminating lamp and power supply it is provided with in illumination box 9，Switch 10、Illuminating lamp and power sources in series，Lever includes holding post 11 and bottom plug 12，Hold post 11 and bottom plug 12 is connected by the mode of screw thread，Hold and post 11 is provided with observation port 13，Hold and in post 11, be provided with drawing box 14，Two containers 15 it are provided with in drawing box 14，Place test device and alarm device respectively，Drawing box 14 and bottom plug 12 connect，Electromagnetic shaker 8 and safe tentacle electrode 9 connect，Lever is provided with finger grip district 16.
During use, hand-held voltage test pencil, it is put into district to be measured, finger pressing hands touched electrode 5 and safety hand touched electrode 9, observe whether neon tube 3 lights, the magnitude of voltage in voltmeter 7 readout line can be passed through simultaneously, when the magnitude of voltage in test line is higher than the safe voltage of human body, voltmeter 7 registration reaches warning value, and vibrator 8 shakes, safety hand touched electrode 9 shakes therewith, tester can feel dangerous information and stop test in time, even if nor affecting on use under dark working environment, when using under dark working environment, by switching 10 unlatching illuminating lamps, convenient use.
To sum up, this utility model produces a desired effect.
