INDUCTION COIL FOR CORDLESS ENERGY CHARGING AND DATA TRANSFER

摘要

An induction coil for cordless energy charging and data transfer, which is used for charging a battery and transferring the data by using an induction connection between a charger and a battery without a direct electric contact, is disclosed. The induction coil is formed such that more than two printed circuit boards, on which a prescribed circuit pattern is formed, are laminated, wherein first ends positioned on an outside of the circuit patterns are electrically connected by a first connection part penetrating the first ends, and second ends positioned on an inside of the circuit patterns are electrically connected by a second connection part penetrating the second ends.
