  • Patent number: 7786834
    Abstract: An inductor 10 has a magnetic body 11 of a rectangular solid shape and a coil 12 embedded in the magnetic body 11. The coil 12 integrally has a part constituted by a helically wound coil wire, two leader parts 12a provided at the two ends of the wound part, and terminal parts 13 connected to the ends of the leader parts and wider than the leader parts 12a, where the boundary between each leader part 12a and each terminal part 13 is positioned in the magnetic body 11, and the end of each terminal part 13 is exposed from the corresponding side face of the magnetic body 11 and folded in an L shape along the side face and bottom face.
    Type: Grant

  • Patent number: 7215232
    Abstract: A surface mount coil component has an electrode part including: internal electrodes mounted on both flanges of a drum type core over bottom surfaces and wraparound portions extending from the bottom surfaces to the end surfaces and parts of both sides. The coil conductor is conductively joined to the internal electrodes at both ends thereof. Intermediate electrodes cover from the top sides of wraparound portions of the internal electrodes on the sides of the flanges through top sides of the wraparound portion thereof on the end surfaces of the flanges to top sides of the wraparound portion thereof on the other sides of the flanges so as to leave C-shaped cross section of exposed areas of the internal electrodes. Also, plating conductive films extend from surfaces of the exposed areas of the internal electrodes to surfaces of the intermediate electrodes.

  • Patent number: 6018134
    Abstract: A main circuit portions are arranged in the order of a breaking section fixed-side conductor, a breaking section movable-side conductor, a disconnecting section movable-side conductor, and a disconnecting section fixed-side conductor, and first and second grounding conductors are respectively provided for grounding the breaking section fixed-side conductor and the disconnecting section fixed-side conductor at both end portions of the apparatus. The arrangement of operating devices is set in the order of a first grounding-section operating device, a breaking-section operating device, a disconnecting-section operating device, and a second grounding-section operating device. In addition, a breaking section is supported by a single supporting insulator to reduce the number of creepage insulation portions.
