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. An object comprising:

a housing for facing a primary coil;

a secondary coil for receiving power from the primary coil; and

a mounting part mounting the secondary coil to the housing,

wherein the mounting part comprises;

a first internal rod part shaped like a rod, oriented lengthwise in a traveling direction, and having a first length approximately equal to a length of the housing in the traveling direction,

a second internal rod part shaped like the first internal rod part, oriented parallel to the first internal rod part, and having a second length approximately equal to the first length,

a left series of left rod parts, oriented in series near a left side of the housing, each left rod part having a left rod length of less than half of the first length, and each left rod part separated from any adjacent left rod part by one left rod clearance,

a right series of right rod parts, oriented in series near a right side of the housing, each right rod part having a right rod length of less than half of the first length, and each right rod part separated from any adjacent right rod part by one right rod clearance, and

wherein the first internal rod part, the second internal rod part, the left series of left rod parts, and the right series of right rod parts are all parallel and co-planar.
