摘要： An ignition coil is provided. The ignition coil comprises a casing, a plurality of pins and a bobbin. The pins are disposed inside the casing. The bobbin, having a plurality of first terminals corresponding to the pins respectively, is disposed inside the casing. Each of the first terminals is provided with a ring-shaped portion in contact with the corresponding pin. Hence, resin, filled in the ignition coil, is prevented from leaking out of the casing.

摘要： A wire-winding structure and method are applied to a transformer to improve transformer power. The wire-winding method includes the following steps. A bobbin which includes a plurality of pins and a plurality of slots on the external surface is provided. A wire is wound from a first pin and successively wound on the rest of the plurality of slots, but not on a slot adjacent to a predetermined connection portion between iron core structures of the transformer. The wire is soldered to a second pin and the bobbin with the winding wire is combined with the iron core structures to constitute the transformer.

摘要： A bobbin for a transformer is provided. The bobbin comprises a body, a first partition wall, a second partition wall, at least one third partition wall, and two first pins. The first partition wall, having a first protrusion, is formed on the body. The body is divided into a primary side and a secondary side by the first partition wall. The second partition wall, having a second protrusion with a thinner section, is formed on the secondary side of the body. The third partition wall, having a third protrusion with a notch, is formed on the secondary side of the body so that the third partition wall is close to the second partition wall and away from the first partition wall. The first pins are disposed on the secondary side of the body in a substantially U-shape.

The embedded transformer includes a board, a first insulating sheet, a preformed coil, a second insulating sheet, a first core and a second core. Among these, the board includes a conductive pattern formed on an upper surface of the board. A part of said conductive pattern serves as a primary coil of the embedded transformer. The first insulating sheet is formed on the conductive pattern. The preformed coil is formed on the first insulating sheet. The second insulating sheet is formed on the preformed coil. The first core is formed on the second insulating sheet and partially embedded in the board. The second core formed on a lower surface of the board is partially embedded in the board so as to be couple to the first core.

摘要： An electromagnetic interference (EMI) filter includes a first magnetomotive element, a first wire, a second wire, and a second magnetomotive element. The second magnetomotive element forms a closed magnetic loop, which comprises a first portion penetrating a through hole of the first magnetomotive element. Thus, the first wire and the second wire in the Filter filter not only differential mode noise but also common mode noise.
