For solving above-mentioned technical matters, the technical solution used in the present invention is: a kind of multifunctional household type electroscope, comprise driver bit, electroprobe bar, electroprobe insulation shell, battery, spring, electroprobe checking circuit, lighting circuit, described electroprobe insulation shell is built with electroprobe checking circuit, lighting circuit, electroprobe checking circuit, lighting circuit connect battery, electroprobe insulation shell front end is by electroprobe bar connecting screw cutter head, described anode is connected with hand touched electrode through spring, and described electroprobe checking circuit is by neon tube; Current-limiting resistance; Hummer; Triode composition is formed, the connection of the positive pole of battery and the collector of triode VT1, and the emitter of triode VT1 connects the positive pole of hummer, and the negative pole of hummer is connected with the negative pole of battery; The base stage of triode VT1 is connected with the collector of triode VT2, and the emitter of triode VT2 is connected with the negative pole of battery; The base stage of triode VT2 is connected with current-limiting resistance, and current-limiting resistance is connected with neon tube, and neon tube is connected with electroprobe bar; When electric current is through electroprobe bar, neon tube, current-limiting resistance, triode, and form loop through human body, make neon tube luminous, hummer sends sound.
Described lighting circuit is made up of light emitting diode, toggle switch, and the positive pole of described battery is connected with one end of toggle switch, and the other end of toggle switch is connected with the positive pole of light emitting diode, and the negative pole of light emitting diode is connected with the negative pole of battery.
Being provided with insulation course outside described electroprobe bar, causing electric shock for avoiding tester's false touch penholder.Described electroprobe bar is connected with replaceable between driver bit, and driver bit is straight screwdriver head or Philip's head screw cutter head.Described light emitting diode is white light-emitting diode.
Beneficial effect of the present invention: the structure simple structure of electroprobe of the present invention, easy to use, sound and light alarm prompting can be carried out to the charged situation of object, there is provided simultaneously night using function, multiplex sleeve function, adds practicality, thus can ensure work safety and the convenience of domestic consumer.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of multifunctional household type electroscope of the present invention;
Fig. 2 is the circuit diagram of multifunctional household type electroscope of the present invention.
Embodiment
Below in conjunction with accompanying drawing, explanation is further explained to embodiments of the invention.
As Fig. 1, shown in 2, multifunctional household type electroscope of the present invention, comprise driver bit 1, electroprobe bar 2, electroprobe insulation shell 3, light emitting diode 4, neon tube 5, current-limiting resistance 6, hummer 7, triode 8, battery 9, toggle switch 10, pen clip 11, hand touched electrode 12, concentration piece 13, spring 14, insulation course 15.
Word driver bit 1 is after electroprobe bar 2 is fixing, electroprobe bar 2 accesses light emitting diode 4, neon tube 5, current-limiting resistance 6, hummer 7, triode 8, battery 9, toggle switch 10 in electroprobe insulation shell 3, and last battery 9 positive pole is connected with hand touched electrode 12 through spring 14.
Electroprobe bar 2 built-in multiplex sleeve uses when being and overhauling for convenience of tester, for the different fixed forms of electrical equipment, change different instruments, when wanting Philip's head screw cutter head if need make, one word screw terminal 1 can be pulled down rear replacing, electroprobe design adopts the four kinds of driver bits often adopted for subsequent use.
Insulation course 15 is provided with, for preventing tester's in use false touch penholder and cause electric shock outside electroprobe bar 2.
Multifunctional household type electroscope mainly contains electrical verification acousto-optic prompting part and forms with illumination section.Illumination section is commonly called as LED by battery 9, toggle switch 10, light emitting diode 4() form, the positive pole of battery 9 is connected with one end of toggle switch 10, the other end of toggle switch 10 is connected with the positive pole of light emitting diode 4, the present invention adopts white light-emitting diode to throw light on, the negative pole of light emitting diode 4 is connected with the negative pole of battery 10, namely forms complete control circuit.When needs throw light on, toggle switch 10 can be put through, thus throw light on.When not needing to throw light on, toggle switch 10 is reversed.
Electrical verification acousto-optic prompting part is made up of battery 9, neon tube 5, current-limiting resistance 6, hummer 7, triode 8, electroprobe bar 2.The connection of the positive pole of battery 9 and the collector of triode VT1, the emitter of triode VT1 connects the positive pole of hummer 7, and the negative pole of hummer 7 is connected with the negative pole of battery 9; The base stage of triode VT1 is connected with the collector of triode VT2, and the emitter of triode VT2 is connected with the negative pole of battery 10; The base stage of triode VT2 is connected with current-limiting resistance 6, and current-limiting resistance 6 is connected with neon tube 5, and last neon tube 5 is connected with electroprobe bar 2, thus forms complete electrical verification acoustic-optic reminding circuit.When tester's hand contact hand touched electrode 12, when contacting testee with straight screwdriver head 1, if testee is charged, weak current can make neon tube 5 luminous, and concentration piece 13 strengthens the luminosity of neon tube; Make triode 8 successive conductive simultaneously, make hummer 7 send alarm sound, thus realize acousto-optic prompting function.Selection of Battery 3V button cell in electroprobe main body, thus can space be reduced, because electroprobe is not in using, triode VT1, VT2 are in cut-off state, and electric quantity consumption is minimum, thus can ignore, and can not establish gauge tap.
