Electrical grounding arrangement for a printed circuit board of a microwave oven

摘要

The present invention relates to a ground structure of a printed circuit board in a microwave oven, where the microwave oven formed with a screw hole at a tip end of a bar extended from a body thereof and having a jumper wire connected to a ground pattern at around a screw hole formed at a printed circuit board while a bolt is screwed to a control panel through a screw hole formed at the tip end of the bar and through a screw hole formed at the printed circuit board are connected by the jumper wire, so that the printed circuit board is automatically connected and grounded to the body of the microwave oven when the printed circuit board is fastened to the control panel, thereby providing a convenience in assembly of the microwave oven and a stability thereto.
