Abstract
The utility model relates to a three-hole socket wiring testing device. The utility model comprises series circuits in which three resistors R1, R2, R3 which are connected with each other at three points L, N, G are respectively connected in series with light emitting devices VD1, VD2, VD3, wherein, the resistors present a triangle shape; a switch SB and the series circuit of resistors are connected between the points L, G. The wiring situation of three-hole sockets can be simply and conveniently tested by utilizing the utility model.
Description
The utility model is a kind of Three-hole socket wiring pick-up unit.
Three-phase socket should detect its wiring correctness after wiring finishes, if wiring error then may cause equipment, household electrical appliances etc. to be burnt, causes great loss for unit or individual.
The purpose of this utility model is: design a kind of Three-hole socket wiring pick-up unit that can detect Three-hole socket wiring situation simply, easily.
The utility model is included in L, N, 3 of G three resistance R triangular in shape of joining
1, R
2, R
3Respectively with luminescent device VD
1, VD
2, VD
3Series circuit, the series circuit of switch S B and resistance is connected between L, the G point.
Above-mentioned in use A, B, 3 of C are connected to respectively in the jack that is considered as live wire, zero line and ground wire.When wiring is correct, between live wire and ground wire and the zero line voltage is arranged, then the light emitting diode VD between L, N and L, the G
1, VD
2Bright, and the light emitting diode VD between ground wire and the zero line
3Do not work.If live wire and zero line wrong, then VD
1, VD
3Bright, and VD
2Do not work.When live wire and ground wire wrong, VD
1Do not work, then VD
2, VD
3Bright.If when lacking zero line, VD then
1, VD
2, VD
3All luminous.Therefore, utilize the utility model can detect the wiring situation of Three-hole socket simply, easily.
For making the utility model distinguish the wiring situation of right and wrong significantly, above-mentioned delta circuit is connected with warning circuit, make it when a kind of or any incorrect link occurring, just send alerting signal, so that make detection more simple.For example, can warning sounding or luminescent device directly be installed at N, G two ends.
Above-mentioned warning circuit also can be following form: it comprises that one is terminated at the series circuit that input end and diode by resistance, photocoupler that N orders are formed, the negative pole of diode wherein is connected to the G point, the output terminal of photocoupler signal generating circuit taking alarm.Its principle is: when wiring error, there is voltage at the N, the G two ends that should be ground wire and zero line, then make photocoupler luminous, and the triggering warning circuit goes out out alerting signal.
Specifically, signal generating circuit can be by the SCR control alerting signal display circuit work that is connected with the photocoupler output terminal.
For example, power supply and sounding or luminescent device and switch are installed between the silicon controlled both positive and negative polarity, whether by the work of switch control sounding or luminescent device.Perhaps between the silicon controlled both positive and negative polarity, connect power supply and reach the light emitting diode VD that is connected with power supply
5With HA-YMD-12095 II type active loundspeakers device A, light emitting diode VD
5Can after warning, cut off silicon controlled automatically with cooperating of this active loundspeakers device.
The utility model can directly utilize the version of existing plug to realize, promptly utilizes the shell of existing three hole plugs, foregoing circuit of the present utility model is installed in the shell of three hole plug-shaped, and its L, N, 3 of G are connected with inserted link respectively.
In addition, employed switch S B is preferably keyswitch in the utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the wiring diagram of the utility model embodiment;
As shown in the figure, present embodiment comprises the shell and the installation circuit part in the enclosure of a key hole that has three jacks and side, this circuit comprises that one is the delta circuit of drift angle with L, N, 3 of G, leg-of-mutton each limit is the series circuit of resistance and photodiode, wherein, be connected to keyswitch SB and resistance R in addition at L, G two ends
4Series circuit.Between N, G, also be connected to resistance R at 2
5, photocoupler A---4N25 input end and diode VD
4Series circuit, wherein, diode VD
4Negative pole be connected to the G point.The output terminal of photocoupler A passes through resistance R
6Be connected to the G point, and connect the control end of controllable silicon VS simultaneously, the silicon controlled both positive and negative polarity be connected to respectively photocoupler another output terminal and G point, at the silicon controlled both positive and negative polarity and power supply, light emitting diode VD are arranged
5Series circuit with HA-YMD-12095 II type active loundspeakers device HA.Above-mentioned L, N, 3 of G are connected with an inserted link respectively, and three inserted links are passed by the jack of shell.Button SB is installed in the key hole place of shell.
