RESONANCE-TYPE NON-CONTACT POWER SUPPLY SYSTEM, POWER-RECEIVING-SIDE DEVICE AND POWER-TRANSMISSION-SIDE DEVICE
First Claim
1. A power-transmission-side device used in a resonance-type non-contact power supply system, which transmits electric power by a non-contact resonance effect from a power-transmission-side resonance coil part connected to a high frequency power supply by a coaxial cable to a power-receiving-side resonance coil part, the power-transmission-side device comprising:
- a power-transmission-side shield part which is a good conductor and covers from outside to accommodate the power-transmission-side resonance coil part, and which is electrically connected to a housing of the high frequency power supply by an outer conductor of the coaxial cable, anda case connecting part which electrically connects the power-transmission-side shield part to a power-receiving-side shield part which is a good conductor and covers from outside to accommodate the power-receiving-side resonance coil part so that a positional deviation between the power-transmission-side shield part and the power-receiving-side shield part can be absorbed.

Abstract
A resonance-type non-contact power supply system includes a power-transmission-side metal shield to cover an area around a primary coil and a primary resonance coil, and a power-receiving-side metal shield to cover an area around a secondary coil and a secondary resonance coil, and when charging is performed, the power-transmission-side metal shield and the power-receiving-side metal shield are connected with a case connector to be at the same potential.
