[0030] Specific workflow:

[0031] During the debugging and installation work, the workers remove part of the outer skin of the wires in advance, and insert the wires into the clamping cavity 22 in sequence according to the live wire and the live wire, and the neutral wire and the neutral wire. At this time, the core of the wire is found between the left and right symmetrical clamping conductive plates 17, and the electromagnets 23 with opposite magnetic forces start to start, and then the left and right symmetrical electromagnets 23 approach each other, thereby clamping and fixing the wires with the outer skin.
