The primary coil includes a primary core formed of magnetic material and a length of winding wire wounded around the primary core. The secondary coil includes a bar-shaped secondary core formed of magnetic material, a length of winding wire wounded around the secondary core and a magnetic sheet attached to at least one of end faces of the secondary core. The magnetic sheet includes a close-contact portion placed in close-contact with the end face of the secondary core and a curved portion which extends outwards from the close-contact portion beyond an outer edge of the end face and whose normal line has a portion un-parallel with an axial direction of the secondary core."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contactless power supply mechanism and secondary coil for contactless power supply mechanism","description":"In a contactless power supply mechanism, a power receiving unit for supplying power to an electric device includes a secondary coil and a power supplying unit for supplying power to the power receivin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9748038","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
