    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 support is used to modify an inductive device to a surface mounting device. The inductive device is provided with a core and a coil, and the support includes an electric portion and an isolation portion. The electric portion, having a first surface and a second surface opposite to the first surface, is electrically coupled to the coil. The first surface of the electric portion is in contact with the core. The isolation portion is disposed on the second surface of the electric portion in a manner such that the isolation portion covers one part of the second surface of the electric portion. The isolation portion is flush with the other part of the second surface of the electric portion.

    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： The transformer bobbin of the present invention includes a tubular body, a first partition wall, at least one second partition wall, at least one third partition wall and pins. The first partition wall is formed on the surface of the tubular body. The first partition wall includes a first flange having a thinner section for providing winding of a wire. The first partition wall separates a primary side from a secondary side. The second partition wall, parallel to the first partition wall, is formed on the surface of the tubular body. The second partition wall includes a second breach and a second flange having a second cut corner formed thereon. The third partition wall, interposed between the adjacent second partition walls, includes a third breach and a third flange having a third cut corner formed thereon. There is a horizontal height difference exists between the second cut corner and the third cut corner.

    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.

    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.
