<p>PURPOSE:To contrive improvement in power transfer characteristics by a method wherein a power supply part and a power receiving part are positioned in close vicinity or they are contacted with each other, and a closed magnetic circuit in which the first and the second cores penetrate the primary and the secondary windings is formed. CONSTITUTION:An inserting part 8 is constituted on one of the opposing terminals 2a and 6a of the first core 2 and the second core 6, and in order to constitute its receiving part 9 on the other opposing terminal, the inserting part 8 is inserted into the receiving part 9 when a closed magnetic circuit is formed by the first core 2 and the second core 6, as the opposing surfaces of the first core 2 and the second core 6 on the inserting part 8 and the receiving part 9 are widened three dimensionally, their opposing area can be enlarged. Accordingly, the opposing area can be made larger without specially constituting the opposing terminals 2a and 6a of the first core 2 and the second core 6 larger than the other parts of the first core 2 and the second core 6. Even when a gap is generated between the first core 2 and the second core 6, the magnetic reluctance generated by the gap can be made small sufficiently, and the magnetic reluctance as the entire closed magnetic circuit can also be made small. As a result, the characteristics of power transfer can be improved.</p> |
