Abstract
A combined structure of hollow bobbin and conductive sheet for a transformer includes a hollow bobbin and at least one conductive sheet. The hollow bobbin includes an outer surface and at least one positioning structure formed on the outer surface. The conductive sheet is fit on the outer surface of the hollow bobbin and includes a main body and at least one engaging structure. The main body has a hollow portion, making the main body to have an inner circumference. The engaging structure is formed on the inner circumference of the main body and is engaged with the positioning structure of the hollow bobbin. The transformer includes at least one winding disposed on the outer surface of the hollow bobbin and abutting against the conductive sheet.
