Abstract

Official abstract text for this publication.

A composite coil device includes a winding shaft portion, a first conductor portion, and a second conductor portion. The winding shaft portion at least partly includes a magnetic body and axially includes a first section and a second section. The first conductor portion is wound continuously in the first section and the second section. The second conductor portion is wound in the second section.

First claim

Opening claim text (preview).

What is claimed is: 1. A composite coil device comprising: a winding shaft portion at least partly including a magnetic body and axially including a first section and a second section; a first conductor portion and a third conductor portion wound continuously in the first section and the second section; and a second conductor portion wound in the second section, wherein at least a part of a core of the magnetic body is attached to a concave portion of a bobbin having an opening, and the first conductor portion and the second conductor portion are wound around and contact both the core and the bobbin. 2. The composite coil device according to claim 1 , wherein the first conductor portion and the second conductor portion are wound in mutually different layers at least in the second section. 3. The composite coil device according to claim 1 , wherein the winding shaft portion includes a partition wall for partitioning the first section and the second section. 4. The composite coil device according to claim 3 , wherein the winding shaft portion includes a notch connecting the first section and the second section. 5. The composite coil device according to claim 4 , wherein the notch is formed on a mounting surface side of the composite coil device. 6. The composite coil device according to claim 1 , wherein the bobbin is disposed on a mounting surface side of the composite coil device. 7. The composite coil device according to claim 6 , wherein the core comprises separatable members combined with each other. 8. The composite coil device according to claim 1 , wherein the core comprises separatable members combined with each other. 9. The composite coil device according to claim 1 , wherein the magnetic body has a shape for forming a closed magnetic path in the first section and/or the second section. 10. The composite coil device according to claim 1 , wherein the magnetic body has a plate member in the first section and/or the second section. 11. The composite coil device according to claim 1 , wherein the second conductor portion comprises at least two conductor wires bifilar-wound around the winding shaft portion. 12. The composite coil device according to claim 1 , wherein a spacer for preventing a winding disturbance of the first conductor portion or the second conductor portion is disposed on the winding shaft portion located in the first section or the second section. 13. A composite coil device comprising: a winding shaft portion at least partly including a magnetic body and axially including a first section and a second section; a first conductor portion wound continuously in the first section and the second section; and a second conductor portion wound in the second section, wherein at least a part of a core of the magnetic body is attached to a concave portion of a bobbin having an opening, the first conductor portion and the second conductor portion are wound around and contact both the core and the bobbin, the winding shaft portion includes a direction-changing portion, and the first conductor portion is wound around the direction-changing portion in opposite directions between the first section and the second section.
