As shown in fig. 2, when 220V ac power inputted from two power line incoming terminals L and N in the panel socket body enters two terminals 1 and 2 of the power input of the switching power supply a1 at ordinary times, the switching power supply a1 outputs stable 6V dc power to the 3 and 4 pins under the action of its internal circuit, and then the power is inputted into the collector of the phototransistor and the negative power input terminal of the relay K built in the opto-electronic module opto-coupler a and the two power input terminals of the opto-electronic switch a2, so that the opto-electronic module and the opto-electronic switch a2 are in the power-on working state. In the photoelectric switch a 2: when the user inserts the power plugs (three plugs) of the electrical equipment JD into the power output plug posts CZ (three jacks, two power output jacks and one ground wire jack) in the panel socket body from the front outer side end of the panel socket body, or before the power plug is pulled out from the power output plug wire pile CZ of the panel socket body by hands, because the detecting head of the photoelectric switch A2 is positioned at the front upper end of the panel socket body, the detecting head detecting distance of the photoelectric switch A2 is about 10 cm, therefore, at the moment, a human hand can temporarily block infrared light emitted by a detecting head of the photoelectric switch A2, so that a pin 3 of the photoelectric switch A2 can output a high level to enter an anode power supply input end of the relay K1, and the relay K1 (a cathode of the relay is communicated with the pin 3 of the switching power supply A1) is electrified to attract two control power supply input ends and two normally closed contact ends of the relay to be respectively opened; because two control power supply input ends of the relay K1 are respectively connected with two 220V alternating current inlet wire ends L and N in the panel socket body, two normally closed contact ends of the relay K1 are respectively connected with two control power supply input ends of the relay K, and the two normally closed contact ends of the relay K are respectively connected with two power output plug wire piles CZ in the panel socket body, at the moment, the 220V alternating current power supply cannot be output to the two power output plug wire piles CZ in the panel socket body, namely, even if the power plug of the electrical equipment JD leaks electricity, no output power supply exists in the two power output plug wire piles CZ in the panel socket body, and then no electric shock accident can be caused; the electric leakage of the plug when the plug is plugged in or pulled out or the electric shock accident caused by the fact that a child at home touches the jack of the panel socket body with a hand are prevented. After the JD plug of the electric equipment is inserted, the human hand can leave the detection range of the detection head of the photoelectric switch A2, because the distance between the human and the detection head of the photoelectric switch A2 is far more than 10 cm, therefore, at the moment, the pin 3 of the photoelectric switch A2 stops outputting the positive power supply to enter the positive power supply input end of the relay K1, the two control power supply input ends and the two normally closed contact ends of the relay K1 are respectively communicated when the relay K1 is powered off, thus, the 220V alternating current power supply can be output to the power plug of the electric equipment JD through the two power output plug wire piles CZ in the panel socket body, the electric equipment can be normally used, because the distance between the human hand and the detecting head of the photoelectric switch A2 is far more than 10 cm when the user operates the corresponding key of the electric device JD, therefore, when the hand normally operates the key of the electric equipment JD, the electric equipment JD cannot be powered off, and the electric equipment JD cannot normally operate.

As shown in fig. 2, when a power plug of an electric device JD is inserted into a jack in a panel socket body, and when the electric device leaks electricity due to various reasons during use, a phase line (live line) enters an earth wire plug KT1 in the panel socket body through a casing KT of the electric device JD, an earth wire terminal of a power plug of a household electric device JD, and since a rear end of the earth wire plug KT1 in the panel socket body, a zero line incoming end N of the panel socket body, the other end of two ac power input ends of a photovoltaic module, a resistor R1 and a cathode of a diode VD1 are respectively connected, a current of the live line leaking at this moment is reduced by the resistor R1 to be limited in current and enters an anode of a light emitting diode hidden in an opto-coupler a, and the light emitting diode is powered to emit infrared light (the diode VD1 plays a role in rectification); when the light emitting diode built in the optical coupler A emits light, the light receiving surface of the phototriode built in the optical coupler A is illuminated to conduct the emitter of the phototriode built in the optical coupler A and output high level to trigger the silicon controlled rectifier VS to conduct (the resistor R2 is a peripheral element of the phototriode built in the optical coupler A); after the silicon controlled rectifier VS is conducted, a positive power supply output by a pin 3 of the switch power supply A1 can enter a buzzer B and a relay K positive power supply input end at the same time, and because the buzzer B and the relay K negative power supply input ends are communicated with a pin 4 of the switch power supply A1, at the moment, the relay K can be electrified to attract two control power supply input ends and two normally closed contact ends of the relay K to be respectively opened, the buzzer B can be electrified to emit a loud prompt sound to prompt a user that the electric equipment JD has an electric leakage accident, and a power plug can be taken down in time to ask a technician to overhaul; because, two control power input ends of relay K1 and two 220V exchange inlet wire end L and N in the panel socket body are connected respectively, two normally closed contact ends of relay K1 and two control power input ends of relay K are connected respectively, two normally closed contact ends of relay K and two power output plug wire stakes CZ in the panel socket body are connected respectively, so at this moment, 220V alternating current power supply can not export this internal two power output plug wire stakes CZ of panel socket, that is to say, after the consumer JD breaks down and leaks electricity, this internal two power output plug wire stakes CZ of panel socket can stop output power, and thus, consumer JD also can stop work, prevented at consumer JD electric leakage, the user leads to the electric shock accident after contacting the casing of consumer, can also prevent to continue to work after the consumer JD electric leakage and cause the damage. Because the controlled silicon VS is always in a conducting state even if the control electrode has no trigger power supply after being conducted, under the actual condition, after the electric equipment leaks electricity, the relay K can be always electrified to attract, the buzzer B can always sound, after a power plug of the fault electric equipment is taken down, in order to be used normally next time, a user firstly presses a button to close the power switch S (a inching type normally closed contact microswitch), because the other end of the power switch S is connected with the VS anode of the controlled silicon, the VS anode of the controlled silicon is powered off, the cathode stops outputting the power supply, the relay K and the buzzer B are powered off simultaneously, after the hand is released, two contacts of the power switch S are closed, two control power supply input ends and two normally closed contact ends of the subsequent relay K are closed again respectively, two power supply output plug wire piles in the panel socket body output the power supply again, and preparing for the next insertion of the JD power plug of the power-free electric equipment. The resistance R1 is 100K; the resistance R2 is 1K; the silicon controlled rectifier VS is a plastic-packaged unidirectional silicon controlled rectifier with the model MCR 100-6; relay K, K1 is a 6V relay of the brand Songle having two power inputs, two normally closed contact ends, two normally open contact ends and two control power inputs. This novel adopt small-size component as far as possible, can be easy to assemble in the rear end casing of panel socket body, its low cost can bring good safe effect for the user.
