[0001] The utility model relates to the technical field of power equipment, and specifically, to a three-phase power input four-in-one power cord. Background Art

[0002] In recent years, with the continuous improvement of the economic development level in China, the electricity consumption of various domestic industries and residents has shown a steady growth trend. People have higher and higher demands for electricity use, higher and higher requirements for the electricity use experience, and the requirements for power supply reliability also increase with the continuous improvement of the quality of life. For the replacement work of the electric energy metering device, it will inevitably lead to the power outage of the back-end user lines. The complex environment at the construction site and the number of work items will directly affect the power outage duration of the on-site users. Long-term power outage operations will bring a bad electricity use experience to users. At the same time, the process of disassembling and replacing the electric energy meter is relatively troublesome, and there is a risk of incorrect wiring or missed wiring during the connection process of different phase lines. Therefore, the power-off meter replacement auxiliary device came into being. When using the power-off meter replacement auxiliary device, three-phase power needs to be connected to the power-off meter replacement auxiliary device. At present, how to safely, simply and quickly connect three-phase power to the power-off meter replacement auxiliary device is a technical hot spot.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a three-phase power input four-in-one power cord, including four fully enclosed alligator clips, four rubber wires and a self-locking four-core socket male head. The four fully enclosed alligator clips are respectively and correspondingly connected to one end of the four rubber wires. The other ends of the four rubber wires are respectively and correspondingly connected to four welding needles at the tail of the self-locking four-core socket male head. The four welding needles at the tail of the self-locking four-core socket male head are correspondingly connected to four pin holes at its head. Three of the rubber wires are connected to three-phase power through the corresponding fully enclosed alligator clips, and the remaining one rubber wire is connected to the neutral line through the corresponding fully enclosed alligator clip.

[0006] Based on the above, the colors of the three fully enclosed alligator clips corresponding to three-phase power are yellow, green and red respectively, and the color of the fully enclosed alligator clip corresponding to the neutral line is black.

[0007] Based on the above, the colors of the four rubber wires are yellow, green, white, and black, and the four fully enclosed alligator clips of yellow, green, red, and black respectively correspond to the four rubber wires of yellow, green, white, and black one by one.

[0008] Based on the above, the four rubber wires are wrapped together by a rubber sleeve. One end of the rubber sleeve is near the four fully enclosed alligator clips, and the other end of the rubber sleeve is fixedly embedded into the tail end of the housing of the self-locking four-core jack male head.

[0009] The utility model has substantial features and progress compared with the prior art. Specifically, when the utility model is in use, the self-locking four-core jack male head is correspondingly plugged into the three-phase power input female head on the power-off meter replacement auxiliary device that matches it. Then, use the three fully enclosed alligator clips of yellow, green, and red to connect to the three-phase power respectively, and at the same time use the black fully enclosed alligator clip to connect to the neutral wire. The three-phase power is connected to the corresponding three pinholes through the three rubber wires of yellow, green, and white, and the neutral wire is connected to the remaining pinhole through the black rubber wire. The four pinholes then connect the three-phase power and the neutral wire to the three-phase power input female head, thereby completing the connection of the three-phase power to the power-off meter replacement auxiliary device. The three fully enclosed alligator clips of yellow, green, and red do not distinguish the phase and can be connected in any order. The operation is simple, safe and reliable. Using the fully enclosed alligator clips can quickly connect the three-phase power to the power-off meter replacement auxiliary device with high efficiency. The self-locking four-core jack male head is used to connect to the three-phase power input female head on the power-off meter replacement auxiliary device that matches it, effectively preventing electric leakage, improving the safety factor, and preventing wrong connection or missed connection.
