Abstract
A transformer includes a first bobbin piece, a second bobbin piece, a first pin, a second pin and a magnetic core assembly. The first bobbin piece has a first channel therein and a covering element, and a primary winding coil is wound on the first bobbin piece. The second bobbin piece includes a first secondary side plate, a second secondary side plate, a plurality of partition plates, a wall portion, and a secondary base, and a secondary winding coil is wound on the second bobbin piece. The second pin includes a wire-arranging part, an insertion part and an intermediate part, wherein the wire-arranging part is protruded from the second secondary side plate, the intermediate part is buried in the wall portion, and the insertion part is protruded from the bottom surface of the secondary base. The magnetic core assembly is partially embedded within said first channel of said first bobbin piece and said second channel of said second bobbin piece. A first terminal of the secondary winding coil is fixed on the first pin and a second terminal of the secondary winding coil is fixed on the wire-arranging part of the second pin. At least parts of the second bobbin piece are received in the covering element of the first bobbin piece, and the covering element has an insulating partition for isolating the magnetic core assembly from the primary winding coil and the secondary winding coil.
