Abstract
The invention discloses a capacitor of a dry type microwave oven, comprising a shell, a capacitor core, a discharging resistor, flat quick-connection inserting pieces, an upper cover, and a filling and sealing material, wherein the capacitor core is formed by winding a metallized polypropylene film; a hollow core rod is arranged in the middle of the capacitor core; the upper cover is provided with square holes; the flat quick-connection inserting pieces are inserted into the square holes; the discharging resistor is positioned between the upper cover and the capacitor core; and the two ends of the discharging resistor are electrically connected with the corresponding flat quick-connection inserting pieces respectively. The capacitor has the characteristics that since the capacitor is not an oil-immersion type capacitor, the bulging and oil leakage of the shell can not easily occur, even the firing phenomenon can not easily occur; and the discharging resistor is positioned between the upper cover and the capacitor core, and leading wires at the two ends are shorter, and are sealed and fixed by the filling and sealing material so as not to be easy to displace.
