Abstract

Provided is a coil mounting structure for a device that comprises a primary coil to be supplied with an alternating current, and a secondary coil arranged facing the primary coil and configured to supply an electric power to a load provided in a housing by using an induced voltage generated by an electromagnetic field produced by the primary coil. The coil mounting structure comprises at least one mounting part provided in a region of the housing, the region facing the primary coil, and the at least one mounting part is configured to hold the secondary coil to the housing. The at least one mounting part comprises at least one gap area configured to interrupt a circuit generated by the at least one mounting part.

Claims

1. A coil mounting structure for a device that comprises a primary coil to be supplied with an alternating current, and a secondary coil arranged facing the primary coil and configured to supply an electric power to a load provided in a housing by using an induced voltage generated by an electromagnetic field produced by the primary coil, the coil mounting structure comprising:

at least one mounting part provided in a region of the housing, the region facing the primary coil, and the at least one mounting part configured to hold the secondary coil to the housing,

wherein the at least one mounting part comprises at least one gap area configured to interrupt a circuit generated by the at least one mounting part.

2. The coil mounting structure according to claim 1, wherein an insulating part containing an insulating material is provided in the at least one gap area.

3. The coil mounting structure according to claim 1,

wherein the at least one mounting part has a stick-like elongated shape,

wherein the at least one mounting part comprises a plurality of mounting parts, and

wherein the plurality of mounting parts are arranged side-by-side and spaced apart from one another so as to form the at least one gap area.

4. The coil mounting structure according to claim 3,

wherein at least one of the plurality of mounting parts contains a non-metallic material having an electrical conductivity lower than an electrical conductivity of a metallic material.

5. The coil mounting structure according to claim 4,

wherein the at least one of the plurality of mounting parts that contains the non-metallic material is arranged at least at one end of both ends of an arrangement of the plurality of mounting parts.

6. The coil mounting structure according to claim 3,

wherein at least one of the plurality of mounting parts comprises a clearance configured to separate the stick-like elongated shape.

7. The coil mounting structure according to claim 6,

wherein the at least one of the plurality of mounting parts that is provided with the clearance is arranged at least at one end of both ends of the arrangement of the plurality of mounting parts.

8. The coil mounting structure according to claim 3,

wherein the housing is at least part of a moving object, and

wherein the plurality of mounting parts are arranged to extend in a traveling direction of the moving object.

9. The coil mounting structure according to claim 3,

wherein the housing is at least part of a moving object, and

wherein the plurality of mounting parts are arranged to extend in a guiding direction that intersects with the traveling direction of the moving object.

10. The coil mounting structure according to claim 1, further comprising a protection cover that is configured to surround a circumference of the secondary coil and that opens towards the primary coil,

wherein the protection cover contains a non-metallic material having an electrical conductivity lower than an electrical conductivity of a metallic material.
