Abstract
Official abstract text for this publication.
A coil fixing structure includes a substrate, which has a thickness in a vertical direction, and a coil, which is wound around an axis extending in a vertical direction and fixed to the substrate. The substrate includes a conductor portion and an insulating portion disposed on the conductor portion. The conductor portion includes a first land portion and a second land portion, which are exposed from an upper surface of the substrate. A first lead wire drawn from the coil has an end portion connected to the first land portion. A second lead wire drawn from the coil has an end portion connected to the second land portion. When viewed in a plan in the vertical direction, the first land portion and the second land portion are disposed to surround the coil.
First claim
Opening claim text (preview).
What is claimed is: 1. A coil fixing structure comprising: a substrate, which has a thickness in a vertical direction; and a coil, which is wound around an axis extending in a vertical direction and fixed to the substrate, wherein the substrate includes a conductor portion and an insulating portion disposed on the conductor portion, wherein the conductor portion includes a first land portion and a second land portion, which are exposed from an upper surface of the substrate, wherein a first lead wire drawn from the coil has an end portion connected to the first land portion, wherein a second lead wire drawn from the coil has an end portion connected to the second land portion, and wherein, when viewed in a plan in the vertical direction, the first land portion and the second land portion are disposed to surround the coil. 2. The coil fixing structure according to claim 1 , wherein the coil is bonded to the substrate with a bonding agent. 3. The coil fixing structure according to claim 2 , wherein the first land portion and the second land portion have substantially equal lengths in a circumferential direction around the axis. 4. The coil fixing structure according to claim 3 wherein, when viewed in a plan in the vertical direction, a shape including an inner edge of the first land portion and an inner edge of the second land portion is similar in shape to an outer edge of the coil. 5. The coil fixing structure according to claim 4 , wherein the first land portion and the second land portion each include a plurality of sub-land portions arranged in the circumferential direction around the axis, and at least one connector connecting adjacent two of the sub-land portions. 6. The coil fixing structure according to claim 4 , wherein the first land portion and the second land portion each include a plurality of sub-land portions arranged in the circumferential direction around the axis, and wherein, when viewed in a plan in the vertical direction, the insulating portion is disposed between adjacent two of the sub-land portions.
