Abstract
This invention relates to a magnetron of a microwave oven is disclosed including a lead for supporting a filament, and a filament terminal for electrically connecting the lead and a choke coil, wherein the filament terminal has a slit and serves to cut off unnecessary high harmonic leaked out to an input of the magnetron.
Claims1
A magnetron of a microwave oven, comprising a lead for supporting a filament, and an filament-terminal for electrically connecting said lead and a choke coil,
- wherein said filament-terminal has a slit which is constructed and arranged to suppress unnecessary higher harmonic leaked out to an input of said magnetron;
- wherein said filament-terminal comprises a wing having said slit;
- and
- wherein the overall length of said slit is one fourth the wavelength of a higher harmonic required to be suppressed.
