Two positioning plates 26 are also mounted on the lower surface of the stationary contacts 28. Two second terminals 30 are fixedly connected to the other ends of the positioning plates 26. Upon receiving the leakage current detection signal, the circuit is quickly cut off to prevent the leakage current from continuing to transmit, ensuring the safety of personnel and equipment. The six terminals 10 internally connect to one end of two No. 1 connecting wires 11, two No. 2 connecting wires 15, one No. 3 connecting wire 16, and one No. 4 connecting wire 17. The other ends of the two No. 1 connecting wires 11 are connected to two sensor fixtures 13. The other ends of the two No. 2 connecting wires 15 are connected to sensor terminals 14. One No. 3 connecting wire 16 is connected to the surface of the coil 23. One No. 4 connecting wire 17 is connected to one end of the positioning plate 26. One side of the positioning plate 26 is connected to the first firing... One end of wire 20 passes through a circular magnetic ring 18 and is connected to one side of mounting base 21. One side surface of positioning plate 26 is connected to one end of the first neutral wire 19, and the other end passes through the circular magnetic ring 18 and is connected to one side of mounting base 21. Two first terminals 22 are respectively connected to the first live wire 20 and the first neutral wire 19, forming a complete power supply circuit. At the same time, they pass through the magnetic ring to form a detection circuit. Two second terminals 30 are respectively connected to the second live wire 31 and the second neutral wire 32. With the above structure, the circuit leakage status is monitored in real time, and the leakage signal is accurately transmitted to the control core, providing a reliable trigger signal for leakage protection action.

[0019] Mounting base 27 is fixedly installed at the center of the upper surface of the two positioning plates 26, and mounting base 29 is fixedly installed on the upper surface of the two positioning plates 26. A second fixing plate 33 is fixedly installed on the inner wall of the outer casing 1. A relay 34 is fixedly installed on the upper surface of the second fixing plate 33. A transformer 35 is fixedly installed on one side of the relay 34. A resistor 36 is fixedly installed on one side of the transformer 35. A capacitor 37 is fixedly installed on one side of the resistor 36. A liquid hydrogen battery 38 is fixedly installed on one side of the capacitor 37. This structure constitutes a socket capable of intelligent timing. A display screen 4 is fixedly installed on the upper surface of the outer casing 1 for easy observation of timing parameters. Several buttons 5 are fixedly installed on the top of the outer casing 1 for timing selection. Two indicator lights 6 are fixedly installed on the top of the outer casing 1 as status indicators, using different colors or flashing patterns to indicate power on / off, timing operation, fault status, etc. A socket 2 is fixedly installed on the top of the outer casing 1 as an external interface for connecting electrical equipment to achieve power output. A fixing block 3 is fixedly installed at the bottom of the outer casing 1, and pins 7 are fixedly installed at the bottom of the fixing block 3 to provide power.

[0020] Working principle: When using the smart timer socket, first connect the external power supply and press button 5 to set the timer start and stop time. Observe the relevant parameters through the display screen 4, and the indicator light 6 will show the indicated working status.

[0021] The first live wire 20 and the first neutral wire 19 pass through the inside of the circular magnetic ring 18 to form a complete current detection circuit. Under normal operating conditions, the current in the live wire and the neutral wire are equal in magnitude and opposite in direction. The combined magnetic field inside the circular magnetic ring 18 cancels each other out and no induced signal is generated. When a leakage occurs in the circuit, some current will be lost through the human body or other paths, resulting in a difference in current between the live wire and the neutral wire. This current difference will cause the circular magnetic ring 18 to generate an induced electromotive force. The induced signal is transmitted to the circuit board 9 for signal processing via the sensor fixing 13, the sensor terminal 14, and the corresponding first connection line 11 and second connection line 15. After the circuit board 9 quickly determines the leakage fault, it sends a drive signal to the pull-in coil 23 through the third connection line 16. After the pull-in coil 23 is energized, it generates an electromagnetic attraction force, which drives the release mechanism 24 fixedly connected to it to move quickly, causing the stationary contact 28 on the positioning plate 26 to separate from the moving contact, thereby cutting off the circuit connection between the first live wire 20, the first neutral wire 19 and the second live wire 31, the second neutral wire 32, and realizing the power-off function.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
