Description

A kind of capacitor for microwave oven
Technical field
The utility model belongs to high-voltage capacitor field, particularly relates to a kind of capacitor for microwave oven.
Background technology
Capacitor for microwave oven is element indispensable in microwave oven, existing capacitor for microwave oven generally comprises metal shell, liquid potting compound, fuse lead-out tablet, core body (do medium with polypropylene screen or kraft capacitor paper, aluminium foil does electrode, through being wound into).In early stage capacitor for microwave oven, generally without blast resistance construction, (blast resistance construction is that the action of blast resistance construction energy forms open circuit when product has problems, product is disconnected from the circuit), like this when electric capacity reaches the working life limit, insulation degree declines, product can not be disconnected from the circuit, produce extraordinary heat to making capacitor cover deformed dilation, final explosion, leakage, on fire, there is serious safety and reliability like this, therefore the explosion-proof performance of capacitor is the problem that each enterprise payes attention to most always, people expect the mode designing a kind of lead-out tablet for this reason, point is welded on the inserted sheet of capacitance cover, by expanding, lead-out tablet is broken by the mechanical displacement produced, thus reach explosion-proof effect, this mode easily pulls inner core body, easily core body is pulled out in unstable situation, very dangerous, often cause dangerous accident, and the mode of traditional capacitor for microwave oven many employings riveted is fixed, repair very inconvenient.
Utility model content
The utility model, for above problem, proposes a kind of capacitor for microwave oven, solves conventional microwave oven capacitor not easy to assemble, and production process for encapsulating requires the potential safety hazard that high and blast resistance construction brings.
The utility model is achieved through the following technical solutions:
A kind of capacitor for microwave oven, comprise aluminum hull, core body, top cover and plug-in unit, described aluminum hull is built with described core body, described core body is provided with lead-out tablet, described plug-in unit is threaded with top cover by fixed cover, also comprise explosion-proof parts and be arranged on the locating piece on described top cover, described locating piece and the inconsistent formation of described top cover completely cut off explosion-proof parts described in chamber and comprise grip block, fixed axis and piston element, described grip block is a pair and symmetrically type distribution, middle part is hingedly coupled on fixed axis, top supported by back-moving spring and with described interposer contact, described lead-out tablet is clamped in bottom, described fixed axis connects described top cover by support bar, described piston element connects described grip block.
The utility model has following beneficial effect:
1. drive grip block action relative to traditional capacitor for microwave oven blast resistance construction of the present utility model by during piston element activity, then grip block is made to unclamp lead-out tablet on capacitance core, thus reach explosion-proof effect, fail safe is higher, and relative to traditional spot-welding technology, clamping contact formula is more convenient when overhauling, and increases piston element in addition and makes structure have better sealing.
2. adopt the fixed form of riveted relative to traditional microwave capacitors fixed cover, the utility model adopts fixed cover to be threaded with top cover, also makes product very convenient when maintenance and dismounting, substantially increase operating efficiency while enhancing steadiness.
3. very convenient when the locating piece in the utility model makes package cap and aluminum hull, enhance the steadiness between top cover and aluminum hull.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, should be appreciated that structure of the present utility model is not limited in following examples:
Embodiment 1: as depicted in figs. 1 and 2, a kind of capacitor for microwave oven, comprise aluminum hull 2, core body 4, top cover 1 and plug-in unit 3, aluminum hull 2 is built with described core body 4, core body 4 is provided with lead-out tablet 7, plug-in unit 3 is threaded with top cover 1 by fixed cover 12, also comprise explosion-proof parts and be arranged on the locating piece 5 on described top cover, described locating piece 5 completely cuts off chamber with the inconsistent formation of described top cover 1, explosion-proof parts comprise grip block 6, fixed axis 10 and piston element 9, grip block 6 is a pair and symmetrically type distribution, middle part is connected through the hinge on fixed axis 10, in normal use procedure, grip block 6 top is supported by back-moving spring 8 and contacts with plug-in unit 3, lead-out tablet 7 is clamped in bottom, fixed axis 10 connects top cover 1 by support bar 11, piston element 9 is connected with the top of grip block 6, when capacitor insulation degree after Long-Time Service declines, produce extraordinary heat, interior pressure increases, piston element 9 is moved up, drive grip block 6 top produces an inside deformation, grip block 6 pressed home spring 8 makes the clamp structure of bottom unclamp, lead-out tablet 7 and grip block 6 noncontact, thus reach explosion-proof effect.
Lead-out tablet is broken by the mechanical displacement produced that expands relative to traditional capacitor for microwave oven, blast resistance construction of the present utility model drives grip block action time movable by piston element, then grip block is made to unclamp lead-out tablet on capacitance core, thus reach explosion-proof effect, fail safe is higher, increasing piston element in addition makes structure have better sealing, thus reach explosion-proof effect, fail safe is higher, and relative to traditional spot-welding technology, clamping contact formula is more convenient when overhauling, the fixed form of riveted is adopted relative to traditional microwave capacitors fixed cover, the utility model adopts fixed cover to be threaded with top cover, make product very convenient when maintenance and dismounting, substantially increase operating efficiency, it is very convenient when locating piece in the utility model makes package cap and aluminum hull, enhance the steadiness between top cover and aluminum hull.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technology people of this area should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
