Abstract
The utility model relates to a feedthru capacitor for a microwave oven magnetron. The utility model comprises one or a plurality of conductors which penetrate the inside and the outside of a magnetron shielding case, wherein, an opening on the metal casing of the magnetron shielding case is closed by an insulation structure which is fixed on the metal casing; the conductor penetrates through the insulation structure which is provided with a mounting plate which is fixed on the metal casing of the magnetron. The mounting plate, which has electric conductive performance, is connected with the metal casing in a conductive connection mode. The conductor penetrates through the mounting plate, and the part of the conductor, which penetrates through the mounting plate, is sheathed on an insulating sleeve barrel. The utility model has the advantages that the expensive insulating ceramic and silver are saved, and the cost of feedthru capacitors is lowered.
Description
1, technical field
The utility model relates to a kind of feed-through capacitor that is used for microwave oven magnetic.
2, background technology
Microwave oven magnetic is understood some harassing and wrecking ripple and is drawn from end in the process of work, in order to reduce the leakage of harassing and wrecking ripple, in the shielding box of magnetron, is provided with the filtering unit that choking-winding and feed-through capacitor constitute usually.Feed-through capacitor is operated under the high pressure-temperature of magnetron, should finish capacitive function, finishes the effect of magnetron energy input channel again.In present technology, the structure of this feed-through capacitor, adopted a built-in insulating ceramics, center conductor is connected with a plane conduction of insulating ceramics, another plane conduction of mounting panel that is connected with magnetron shielding box conduction and insulating ceramics is connected, and this two plane constitutes the accumulate structure of feed-through capacitor.In most cases also need be silver-plated on one or two plane of insulating ceramics, this causes the cost of feed-through capacitor high.
3, summary of the invention
The purpose of this utility model provides a kind of function that can possess feed-through capacitor, but the feed-through capacitor that is used for microwave oven magnetic that cost reduces greatly,
The purpose of this utility model realizes in the following manner.
The utility model comprises and runs through the inside and outside one or more conductors of magnetron shielding box, is provided with opening on magnetron shielding box metal shell, and opening is fixed on the insulation system sealing on the metal shell, and conductor passes insulation system.
The fixing mode of wherein common insulation system is: mounting panel is set on insulation system, and mounting panel is fixed on the magnetron shielding box metal shell.
If mounting panel is a metal, then should be connected with the metal shell conduction, conductor passes mounting panel, conductor and mounting panel insulation.Can pass insulating sleeve on the mounting panel peripheral sleeve partly at conductor, insulating sleeve is plastics, rubber sleeve or pottery.Certainly, also can be provided with the sleeve with the insulation system one at the periphery that conductor passes mounting panel part, promptly insulating sleeve also can be the part of insulation system, is made of one with insulation system.
Good effect of the present utility model be changed insulating ceramics two sides that conventional art adopts respectively with conductor and mounting panel conduction ways of connecting, saved expensive insulating ceramics, silver, reduced the cost of feed-through capacitor.
