<p><P>PROBLEM TO BE SOLVED: To provide a transformer which meets the safety standard, has strong magnetic coupling between a primary winding and a secondary winding, and is reduced in size and height. <P>SOLUTION: A first primary winding 51 is wound around a first section 21A so as not to protrude vertically and horizontally from partitioning plates 22, 23. A first secondary winding 52 and a second secondary winding 53 are wound around a third section 21C so as not to protrude in vertical and horizontal directions from the partitioning plates 22, 23. A second primary winding 54 is formed of a three-layered insulation wire, and serially coupled with the first primary winding 51. The second primary winding 54 is wound around a second section 21B so as not to protrude in vertical and horizontal directions from the partitioning plates 22, 23, and one end and the other end of the second primary winding 54 are led through lead grooves 22a of the partitioning plate 22 to a terminal block 31, while facing the portions corresponding to the lateral edges which define the cross sectional shape of the substantially cylindrical part 21. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
