A single group of power lines consists of two enameled wires, the top of the enameled wires are connected to a coil welding terminal, and the bottom of the enameled wires are connected to an output terminal.

[0006] As a preferred solution, a welding plate is connected to the bottom end of the enameled wire, and two adjacent welding plates are connected to the top of the output terminal by welding.

[0007] As a preferred solution, the output terminal is bent in the middle and a wiring port is provided at the bottom.

[0008] As a preferred solution, the welding plate is ultrasonically welded to the output terminal.

[0009] As a preferred solution, positioning tubes are respectively installed at the front and rear ends of the insulating block.
