NON-CONTACT POWER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power supply device for reducing the effect of a magnetic flux leaked from an opening groove of a core and the effect of a magnetic flux generated around a power supply line disposed outside the core.

SOLUTION: A magnetic shield body 5 is formed in a substantial cylinder by a metallic magnetic material having high magnetic permeability and externally provided on the core 2 and the coil 3. As described above, he core 2 and the coil 3 are enclosed by the magnetic shield body 5, so that a magnetic flux generated around a returning power supply line 100 can be prevented from passing through the inside of the core 2. As the result, the degradation in the efficiency of power transmission of a pickup section 1 can be prevented.
