Abstract
Official abstract text for this publication.
A power reception device includes a flat plate-like core and a coil spirally wound around the core and having a winding central axis extending in a horizontal direction. The coil is formed like a flat plate to have a longer side portion and a shorter side portion when the coil is viewed in cross section at a plane perpendicular to an extending direction of the coil. The coil is wound around the core such that the longer side portion faces a surface of the core. Therefore, the thickness of the power reception device can be reduced.
First claim
Opening claim text (preview).
The invention claimed is: 1. A power reception device, comprising: a flat plate-like core; and a coil spirally wound around the core and having a winding central axis extending in a horizontal direction, the coil being formed like a flat plate to have a longer side portion and a shorter side portion when the coil is viewed in cross section at a plane perpendicular to an extending direction of the coil, the coil being wound around the core such that the longer side portion faces a surface of the core, and the coil being wound around the core in a multi-layer winding manner. 2. The power reception device according to claim 1 , wherein an outer sheath insulator is provided on the surface of the coil and adjacent coils are arranged to be in contact with each other. 3. The power reception device according to claim 1 , wherein the coil has a flat braiding wire structure. 4. The power reception device according to claim 2 , wherein the coil has a flat braiding wire structure. 5. A power reception device, comprising: a flat plate-like core; and a coil spirally wound around the core and having a winding central axis extending in a horizontal direction, the coil being formed like a flat plate to have a longer side portion and a shorter side portion when the coil is viewed in cross section at a plane perpendicular to an extending direction of the coil, the coil being wound around the core such that the longer side portion faces a surface of the core, and the coil being wound around the core such that adjacent coil portions partially overlap each other. 6. The power reception device according to claim 5 , wherein an outer sheath insulator is provided on the surface of the coil and adjacent coils are arranged to be in contact with each other. 7. The power reception device according to claim 5 , wherein the coil has a flat braiding wire structure. 8. The power reception device according to claim 6 , wherein the coil has a flat braiding wire structure.
