TRANSFORMER-MOUNTING BOARD DEVICE OF MICROWAVE OVEN

摘要

PROBLEM TO BE SOLVED: To prevent application of mechanical stress to a connecting portion between a secondary coil terminal of a transformer and a high voltage circuit pattern.SOLUTION: An transformer-mounting board device 20 of a microwave oven includes a board 19 on which a slit 26 is formed to encircle a conductive pattern 21 having a connecting portion 21a connected to a secondary coil terminal 9c1 of a booster transformer 9. An area 19E encircled with the slit 26 on the board 19 is provided with a fixing portion for fixing the booster transformer 9 to the board 19. The secondary coil terminal 9c1 is connected to the connecting portion 21a of the conductive pattern 21, and the booster transformer 9 is fixed to the board 19 by tightening screws 29 and 30 on the fixing portion.
