[0029] In this solution, the connecting wire 2 is passed through the inside of the wire tube 1 and then connected to the detection mechanism 4, enabling the power plug to function. During the use of the plug, the detection mechanism 4 can detect the internal current. When a leakage phenomenon is detected, the prompting mechanism 3 can promptly give a prompt to the user.

[0030] Please refer to Figures 2-5 , the prompting mechanism 3 includes an insulating upper shell 31. A plug strip 32 is fixedly connected to the lower end of the insulating upper shell 31. Two internal threaded holes 33 are opened at the upper end of the insulating upper shell 31. A prompting lamp 34 is fixedly connected to the inner surface of the insulating upper shell 31.

[0031] The detection mechanism 4 includes a relay element 41. A housing assembly 42 is fixedly connected to the lower end of the relay element 41. Two bolts 43 are threadedly connected inside the housing assembly 42. The inner surfaces of the two internal threaded holes 33 are respectively threadedly connected to the outer surfaces of the two bolts 43. Two plug components 44 are fixedly connected inside the housing assembly 42.

[0032] The housing assembly 42 includes an insulating lower shell 421. A slot 422 is opened at the upper end of the insulating lower shell 421. A wiring board 423 is fixedly connected to the bottom wall of the inner cavity of the insulating lower shell 421. The inner surface of the wiring board 423 is threadedly connected to the outer surface of the bolt 43 located at the rear. A current transformer 424 is fixedly connected to the bottom wall of the inner cavity of the insulating lower shell 421. A connecting block 425 is fixedly connected to the bottom wall of the inner cavity of the insulating lower shell 421. The inner surface of the connecting block 425 is threadedly connected to the outer surface of the bolt 43 located at the front.

[0033] The plug component 44 includes a connecting plate 441. The lower end of the connecting plate 441 is fixedly connected to the bottom wall of the inner cavity of the insulating lower shell 421. The inner surface of the connecting plate 441 is fixedly connected to the outer surface of the wire tube 1. An internal threaded tube 442 is fixedly connected to the inner surface of the upper end of the connecting plate 441.

Metal strips 446 are fixedly connected to the inner surfaces of the conductive plates 445.

[0034] In this solution, the connecting wire 2 is passed through the inside of the wire tube 1. Then, the neutral wire and the live wire of the connecting wire 2 are respectively connected to the current transformer 424 and the relay element 41. Finally, the head ends of the two wires are respectively placed on the upper end of the conductive plate 445. Then, a tool is used to turn the two second bolts 443, so that the second bolts 443 move downward on the inner surface of the internal thread tube 442. The downward movement of the second bolts 443 will drive the metal plate 444 to move downward together. At this time, the distance between the metal plate 444 and the conductive plate 445 will become smaller and smaller until the head ends of the wires are tightly clamped. At this time, the neutral wire and the live wire of the connecting wire 2 will be respectively connected to the two metal strips 446.

Then, the two metal strips 446 can be inserted into the jacks for use. When a leakage phenomenon occurs, the current transformer 424 will sense the abnormal current and transmit the current signal to the relay element 41. The relay element 41 will control the circuit to block, avoiding potential safety hazards caused by continuous leakage. At the same time, it will control the warning light 34 to light up, indicating to the user that there is a leakage phenomenon in this power plug.

[0035] It should be noted that the specific installation methods, connection methods of the circuit, and control methods of the current transformer 424, the relay element 41, and the warning light 34 in the present utility model are all conventional designs, and the present utility model will not elaborate in detail.

[0036] Working principle: When using the power plug, first pass the connecting wire 2 through the inside of the wire tube 1. Then, connect the neutral wire and the live wire of the connecting wire 2 to the current transformer 424 and the relay element 41 respectively. Finally, place the head ends of the two wires on the upper end of the conductive plate 445. Use a tool to turn the two second bolts 443 to tightly clamp the head ends of the wires with the metal plate 444 and the conductive plate 445. Then, by using the cooperation of the inserting strip 32 and the slot 422, the insulating upper shell 31 and the insulating lower shell 421 are snap-connected together, and a tool is used to turn the two first bolts 43 to fix the insulating upper shell 31 and the insulating lower shell 421, jointly forming the outer shell of the power plug. Then, the two metal strips 446 can be inserted into the live jacks for use. When a leakage phenomenon occurs, the current transformer 424 will sense the abnormal current and transmit the current signal to the relay element 41. The relay element 41 will control the circuit to block, avoiding potential safety hazards caused by continuous leakage. At the same time, it will control the warning light 34 to light up, indicating to the user that there is a leakage phenomenon in this power plug.
