In addition, according to the disclosure of the foregoing embodiments, the present invention further provides a method of assembling a combined structure of a hollow sleeve and a conductive sheet, which can be substantially as shown in steps S1 to S4 of FIG.

In step S1, a hollow sleeve is provided, wherein the hollow sleeve has an outer surface and at least one positioning structure, and the positioning structure is formed on the outer Above the surface.

In the step S2, at least one conductive sheet is sleeved on the outer surface of the hollow sleeve, wherein the conductive sheet comprises a body and at least one fastening structure, the body is provided with a hollow portion so that the body has a The inner peripheral edge is formed on the inner circumference of the body and is engaged with the positioning structure of the hollow sleeve.

In step S3, at least one winding is disposed on the outer surface of the hollow sleeve and adjacent to the conductive sheet.

Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the present invention, and it is possible to make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
