[0020] The winding structure includes a wire management groove 5-1 that limits the routing of the coil head end and a lead groove 5-2 that limits the routing of the coil end; the structure of the wire management groove 5-1 is formed by extending from the end point of the outer coil of the skeleton 1 to the upper end surface of the derivative part 4, and the enameled wire is routed through the wire management groove 5-1 arranged on the upper end surface of the derivative part 4, and then wound onto the winding terminal 4-1 arranged away from the wire management groove 5-1; the structure of the lead groove 5-2 is formed by extending from the end point of the outer coil of the skeleton 1 to the lower end surface of the derivative part 4, and the enameled wire is routed from the upper end of the wire management groove 5-1, and then routed through the lead groove 5-2 arranged on the lower end surface of the derivative part 4, and then wound onto the winding terminal 4-1 arranged close to the lead groove 5-2.

[0021] The outer end surface of the derivative part 4 is provided with a limiting structure 4-2, which is used to prevent the enameled wire from falling out of the lead groove 4-1 when passing through the lead groove 4-1.
