<p>PROBLEM TO BE SOLVED: To obtain a non contact type transformer which can be manufactured readily at a low cost and has high reliability by constituting a magnetic core of at least one coil of a pair of coils of a plurality of division piece cores, arranged in rotational symmetry of integral turns whose center of symmetry is the rotation axis. SOLUTION: In a non contact type transformer, each coil of an inside core 3 and an outside core forms a pair, thus constituting a transformer. The inside core 3 is tubular and in an outside core, eight rod-like division piece cores 1 whose length direction is the axial direction are arranged and fixed at equal angles in the inner surface of a tubular nonmagnetic holder 9. A coil with the division piece core 1 of an outside core is a primary side coil 5, and a coil with the inside core 3 is a secondary side coil 7. The primary side coil 5 is stored in a groove 14 of the division piece core 1, and the secondary coil 7 is stored in a groove 13. An outgoing line of the secondary side coil 7 is drawn out through the groove 15 formed in the axial direction of the inside core 3.</p> |
