<p><P>PROBLEM TO BE SOLVED: To provide a transformer capable of suppressing the external leakage of magnetic flux. <P>SOLUTION: The transformer 10 is configured to form prescribed closed magnetic paths A, B, C by opposing a core 23 and an I type core 40 to each other. The core 23 includes a case body 12 of a bottomed box shape having a bottom 14 and a side frame 16, supporters 18, 20 extended nearly in parallel from the bottom 14 toward the I type core 40, a stud 22 extended from the bottom nearly in parallel with the supporters 18, 20 from the case body 12 toward the I type core 40, a primary winding 38 wound on the supporter 18, and a secondary winding 39 wound on the supporter 20. The core is extended up to positions in press contact with the I type core 40, and a U type core 40 for leading part of the magnetic flux generated from the primary winding 38 to the case body 12 is arranged in the vicinity of the primary winding 38. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
