Electrostatic coupling type non-contact electric supply device

Japanese Patent JP5980329

B2

The present invention of an electrostatic coupling type contactless electric power supply device 1 has multiple electrodes for contactless electric power supply 41 and a high-frequency power source circuit 5 provided on a fixed section 2, multiple electrodes for contactless electric power reception 61 and an electric power reception circuit 7 on a movable section 3, wherein the electrode for contactless electric power supply 41 and the electrode for contactless electric power reception 61 have base sections 441, 611 with a perpendicular cross sectional shape to the moving direction of the movable section 3 and there are multiple extending tooth sections 412, 612, and fellow tooth sections 412, 612 are mutually alternating and separated to fit together in an interdigitated array electrode, furthermore, the electrode for contactless electric power reception 61 is an interdigitated array electrode with the outer surface of the tooth section 612 covered with a conducting layer 613 and the tooth section 612 internal section and the base section 613 are formed from material that has a smaller specific gravity than the conducting layer. And from this, the electric power supply capacity and electric power supply efficiency of the contactless electric power supply is improved from that conventionally, and the movable section 3 which is the power supply target can be lighter.
