The specific embodiment
Known according to Fig. 1 to Fig. 6, the present invention is made up of caliper, insulated handle, a rim of the mouth, and the front end metal position of caliper 1 is for surveying electric live wire end, and caliper insulated handle 2 is provided with the ground terminal 9 contacting with human body;
Between described live wire end and ground terminal, be provided with can be luminous device 3 or device 4 that can sounding;
In described device 3 that can be luminous, be provided with light-emitting component 5, and for the illuminating circuit 7 of light-emitting component work; Described can be provided with sounding component 6 in the device 4 of sounding, and supplies the phonation circuit 8 of sounding component work;
Described device 3 that can be luminous, and for the illuminating circuit of light-emitting component work, and described device 4 that can sounding, and for the phonation circuit of sounding component work, be all arranged on insulated handle 2;
The leading portion of described caliper 1 is made into a rim of the mouth 10 of in-line.
Described caliper 1 is nipper plier or flat nose pliers.
Described device 3 that can be luminous is arranged on the handle 2 front ends tiger's jaw place of shaking hands, and is an outstanding round platform, and the fixture 51 of installing light emitting element 5 is set in round platform, and light-emitting component 5 belows arrange luminous circuit board 52.
Described device 4 that can sounding is arranged on the handle 2 front ends tiger's jaw place of shaking hands, and is an outstanding cavity round platform, and sounding component 6 is set in round platform, and sounding component 6 belows arrange phonation circuit plate 61.
Described illuminating circuit and phonation circuit are by bridge rectifier D
1connect by trigger tube DW
1,, DW
2with monocrystalline silicon T
1the circuits for triggering of composition, then connect light-emitting component 5 or sounding component 6 by triggering output.
Circuit working principle of the present invention:
As shown in Figure 5, pass through R
1d
1whole bridge and hand touch basic rectification circuit of end composition, its trigger tube DW
1, DW
2with T
1circuits for triggering of monocrystalline silicon composition, provide to DY information ring device the voltage that sends the sound, and its course of work is: when staff contact touches end, just at A, B end forms DC voltage, and its voltage is added in DW
1, DW
2and T
1on the circuits for triggering of composition, due to DW
1,, DW
2under the effect of voltage stabilizing threshold value, at T
1g end produce trigger voltage, T
1conducting, passes through R
2resistance, leakage current, the very fast decline of voltage, T
1g end decompression, conducting cut-off.When voltage rises again, T
1g end again trigger T
1conducting, goes round and begins again, and forms alternating voltage at DY information ring device end, produces the sound, because human body resistance and earth resistance change with condition, and the voltage of the testing circuit that can raise, quickening DW
1, DW
2, T
1threshold rates, same sound and rhythm is accelerated, vice versa.
During due to survey electricity, the decay by interior circuit choked flow (guaranteeing that staff touches safety) with human body and earth resistance, electric current is just very faint, and the DY information ring device sound is affected.Increase a sound-aid cavity to information ring device here, make the sound larger, louder.
As shown in Figure 6, at A, the voltage that B end forms, is full of C
1electric capacity, its voltage rises, at DW
1, DW
2under the threshold function of trigger tube, trigger T
1g end, T
1monocrystalline silicon conducting, LED light emitting diode D
1conducting is luminous, release current, voltage drop, C
