Abstract
The utility model discloses a kind of noinductive capacitor aluminum hull, comprise housing, at least four positioning bars have along the circumferential direction been evenly arranged at described housing, the height of positioning bar is 1-2 times of described thickness of shell, positioning bar is provided with pore, between positioning bar and housing, form explosion-proof deformed area, be provided with the circular arc insulating trip that two central angles are less than 180 ° in the inner side of described explosion-proof deformed area.Described positioning bar is 8-12.Compared with prior art, the utility model capacitor arranges positioning bar in aluminum hull, by positioning bar, capacitor core and aluminum hull interval is played insulation effect, and positioning bar can also improve the intensity of aluminum hull simultaneously, have again, positioning bar has certain height, forms an explosion-proof deformed area, when the overheated explosion time of the capacitor core in inner casing between positioning bar and aluminum hull, volumetric expansion, deformed area just can absorb expansion, guarantees that capacitor case is injury-free, thus improves explosion-proof performance and explosive-proof grade.
Description
Technical field
The utility model relates to a kind of aluminium shell of capacitor, belongs to capacitor technology field in electricity.
Background technology
Capacitor is made up of aluminum hull and capacitor core.Aluminum hull is the shell of capacitor, has protection capacitor core, isolated capacitor core and extraneous effect.The aluminum hull of capacitor of the prior art is stamped to form by aluminium, in order to prevent capacitor core from contacting with aluminum hull, aluminum hull can be made to make the faults such as capacitor core short circuit, one deck dielectric film is all coated with at aluminum hull surfaces externally and internally, and capacitor can generate heat under normal usage, the existence of insulating barrier, can cause dispelling the heat, the service life of capacitor be reduced, even has the possibility of blast.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides the aluminium shell of capacitor that a kind of explosion-proof performance is good.
A kind of noinductive capacitor aluminum hull, comprise housing, it is characterized in that, at least four positioning bars have along the circumferential direction been evenly arranged at described housing, the height of positioning bar is 1-2 times of described thickness of shell, described positioning bar is provided with pore, between positioning bar and housing, forms explosion-proof deformed area, be provided with the circular arc insulating trip that two central angles are less than 180 ° in the inner side of described explosion-proof deformed area.
Described positioning bar is 8-12.
Compared with prior art, the utility model capacitor arranges positioning bar in aluminum hull, by positioning bar, capacitor core and aluminum hull interval is played insulation effect, and positioning bar can also improve the intensity of aluminum hull simultaneously, have again, positioning bar has certain height, forms an explosion-proof deformed area, when the overheated explosion time of the capacitor core in inner casing between positioning bar and aluminum hull, volumetric expansion, deformed area just can absorb expansion, guarantees that capacitor case is injury-free, thus improves explosion-proof performance and explosive-proof grade.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 1, a kind of noinductive capacitor aluminum hull of the utility model, comprise housing 1 and positioning bar 2, wherein positioning bar 2 extends along the short transverse of housing 1 and is distributed on the circumferencial direction of housing 1, the height of positioning bar 2 is 1-2 times of housing 1 thickness, between positioning bar 2 and housing 1, form explosion-proof deformed area, the circular arc insulating trip 3 that disposed inboard two central angles of positioning bar are less than 180 °, positioning bar is processed with pore 4.The quantity of positioning bar is 8-12, and in the present embodiment, positioning bar quantity is 8.
