Abstract

The utility model relates to a double-pole plug for testing the on-off state of a circuit, which is composed of a double-pole plug, a light emitting diode, a neon bulb and a resistor or a capacitor. The utility model is characterized in that the used elements are all arranged in the double-pole safety plug, one pole of the plug for inserting a fire wire is connected in series with a current limiting resistor R1 and the neon bulb outside a fastening screw, and simultaneously, the light emitting diode and a current limiting resistor R2 are connected in series between the pole for inserting a fire wire and a pole for inserting a zero wire. The utility model which has the advantages of simple structure and rapid testing can test the conditions of correct wire connection, the turnoff of a zero wire, the turnoff of a phase wire, the inverse connection of the phase wire and the zero wire, the power supply of 380V of two phases, etc. The utility model is suitable for the rapid test of the on-off state of a circuit.

Description

Double anode plug for testing power on/off

The utility model belongs to the proving installation of electrical property and electric fault, also is the two poles of the earth plug of the quick test of a kind of line connection device, particularly a kind of connecting and disconnecting of the circuit simultaneously.

At present, connecting and disconnecting of the circuit adopts test pencil more, and test pencil is made up of test contact, current-limiting resistance, neon bulb and hand touched electrode, has only test function, can't use as line connection device.And existing plug, socket lack the measuring ability to connecting and disconnecting of the circuit again as line connector.

The purpose of this utility model is that design, a kind of single-phase two spring hole scokets of making the two poles of the earth plug that use, that have the wiring test function to realize the wiring test to circuit, are again safe line connectors simultaneously.

Connecting and disconnecting of the circuit test of the present utility model the two poles of the earth plug, form by the two poles of the earth plug, light emitting diode, neon bulb, resistance or capacitor, it is characterized in that, used element all is contained in the plug cut-out of the two poles of the earth, electrode and current-limiting resistance R1, the neon bulb of the grafting live wire of plug are connected on the trip bolt place, simultaneously, and between the electrode of grafting zero line, series connection light emitting diode and current-limiting resistance R2.

Principle of work of the present utility model is, light emitting diode is through current-limiting resistance or capacitor, is plugged on the live wire, zero line of industrial-frequency alternating current, under the effect of alternating current, have electric current to flow through and cause lumination of light emitting diode, neon bulb is luminous the same with test pencil, has earthing pole to get final product.According to light emitting diode and the luminous situation of neon bulb, get final product the switching of test circuit.

The using method of connecting and disconnecting of the circuit test safety plug of the present utility model:

After holding the two poles of the earth plug trip bolt (extremely linking to each other) insertion socket with one of neon bulb,

If light emitting diode is bright, live wire, zero line connection are described, power;

If it is also bright to be connected on the neon bulb of the right utmost point, illustrate that the socket wiring is correct, meet GB GBJ232-82 regulation: two pole sockets, faces socket, left utmost point connecting to neutral line, the right utmost point line of starting to exchange fire;

If light emitting diode is bright, neon bulb does not work, and illustrates that live wire, the zero line of socket connects instead;

If light emitting diode does not work, neon bulb is bright, and the zero line break of socket is described;

If light emitting diode does not work, neon bulb does not work yet, and position, the two poles of the earth is exchanged in 180 ° of plug cut-out upsets inserted socket, and this moment, neon bulb was bright, illustrated that live wire connects anti-zero line break;

If light-emitting diode luminance obviously improves, neon bulb is also bright, and the insertion that changes over of the two poles of the earth plug, light emitting diode is bright, and neon bulb is also bright, and the power supply of socket two-phase is described.

The advantage that the utlity model has is, simple structure, test rapidly, it is correct to test wiring, zero line break, phase line opens circuit, zero two wires connects anti-situations such as two-phase 380v power supply mutually.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is the electrical schematic diagram of connecting and disconnecting of the circuit test the two poles of the earth plug

Fig. 2 is the structural map of connecting and disconnecting of the circuit test the two poles of the earth plug

As seen from the figure, connecting and disconnecting of the circuit test the two poles of the earth plug, form by the two poles of the earth plug, light emitting diode, neon bulb, resistance or capacitor, it is characterized in that, used element all is contained in the plug cut-out of the two poles of the earth, and electrode 1 and current-limiting resistance R1, the neon bulb 2 of the grafting live wire of plug are connected on trip bolt 3 places, simultaneously, and between the electrode 4 of grafting zero line, series connection light emitting diode 5 and current-limiting resistance R2.
