<p><P>PROBLEM TO BE SOLVED: To provide a high voltage transformer which can wind a secondary winding in oblique lamination without winding in the extension end of the secondary winding. <P>SOLUTION: The high voltage transformer 1 has a bobbin 10 with terminals 12A, 12B provided to a core 13 and opposite ends of the core 13. A primary winding 20 and a secondary winding 21 are wound around an outer circumferential surface of the core 13 each. The core 13 is provided with a flange 16 which divides the core 13 into a primary side core 13A, and a secondary side core 13B along a longitudinal direction. The primary winding 20 is wound around the primary side core 13A and forms a plurality of winding layers parallel to a central axis of the core 13. The secondary winding 21 is wound around the secondary side core 13B, and forms a plurality of winding layers which tilt at a fixed angle to a central axis of the core 13. A groove 18f is formed in at least the primary side core 13A, and an extension end 21a at a winding start side of the secondary winding 21 is housed in the groove 18f. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
