Abstract
The utility model relates to a high voltage capacitor for a microwave oven, which comprises two patching lead ends and a shell, wherein at least one high-voltage diode is mounted between one of the two patching lead ends and the shell. The utility model has the advantages that the design is reasonable, the high-voltage diode is added between one patching lead end and the metal shell, thereby the grounding effect of the high-voltage diode is achieved through the high voltage capacitor grounds, simultaneously when the microwave oven is produced, the trouble of installing two parts is capable of being reduced, and the efficiency of producing the microwave oven is improved.
Description
Technical field
The utility model relates to the high-voltage capacitance that a kind of microwave oven is used.
Background technology
Existing microwave oven need produce microwave energy and generally carry out the processing of half-wave multiplication of voltage in the secondary output of transformer, so just need a high-voltage capacitance and high-voltage diode, usually way is that the high-voltage diode positive pole is connected with electric capacity, negative pole is connected with the microwave oven ground wire, high-voltage capacitance just is fixed on the metallic plate of microwave oven with metal and is connected with power ground by metallic plate, the shell that reaches high-voltage capacitance is connected with ground, and this way can reduce the production efficiency of microwave oven.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of simple in structure, electric capacity of realizing improving microwave oven production efficiency.
Of the present utility model being achieved in that
A kind of electric capacity comprises that two wiring draw end, shell, and described two wiring are drawn between in the end one and the shell and are provided with a high-voltage diode at least.
Above-mentioned purpose also can be done further perfect by the following technical programs:
Described shell is a metal shell, and metal shell is connected with ground, and an end of high-voltage diode directly is connected with metal shell.
Described shell is a non-metal shell, and shell is provided with a sheet metal that is connected with ground, and an end of high-voltage diode directly is connected with sheet metal.
Described high-voltage diode can be placed on the inside or the outside of shell.
The utility model is reasonable in design, draw high-voltage diode of increase between end and the metal shell a wiring, can get to high-voltage diode ground connection effect by the ground connection of high-voltage capacitance like this, the trouble of two parts is installed in the time of can reducing to produce microwave oven simultaneously, improves the efficient when producing microwave oven.
