Abstract
The utility model discloses a kind of polarized capacitor aluminum case with felt pad, comprise housing and the cover plate being positioned at housing upper end, it is characterized in that, one deck insulation spacer is provided with in described cover plate, this insulation spacer has an annular boss, form a cannelure between this annular boss and described cover plate inward flange, the upper end of described housing is positioned at described cannelure.The width of described cannelure is less than the thickness of described housing upper end.Compared with prior art, the utility model aluminium shell of capacitor is on the cover board provided with the insulation spacer that has annular boss, is limited between annular boss and the inner edge of cover plate by the upper end of housing, and the sealing property of housing and cover plate is obviously strengthened.
Description
Technical field
The utility model relates to a kind of polarized capacitor aluminum case, belongs to capacitor technology field in electricity.
Background technology
Electrolytic capacitor is made up of aluminum hull and capacitor core.Aluminum hull is the shell of electrolytic capacitor, has protection capacitor core, isolated capacitor core and extraneous effect.Aluminum hull is generally assembled by housing and cover plate, and youngster's housing and cover plate are aluminum material, and its sealing property is difficult to ensure card, so capacitor can exist the problem of leakage.
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 a kind of polarized capacitor aluminum case of good airproof performance.
A kind of polarized capacitor aluminum case with felt pad, comprise housing and the cover plate being positioned at housing upper end, it is characterized in that, one deck insulation spacer is provided with in described cover plate, this insulation spacer has an annular boss, between this annular boss and described cover plate inward flange, form a cannelure, the upper end of described housing is positioned at described cannelure.
The width of described cannelure is less than the thickness of described housing upper end.
Compared with prior art, the utility model aluminium shell of capacitor is on the cover board provided with the insulation spacer that has annular boss, is limited between annular boss and the inner edge of cover plate by the upper end of housing, and the sealing property of housing and cover plate is obviously strengthened.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the utility model cover plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 1, a kind of polarized capacitor aluminum case of the utility model, comprises housing 1 and the cover plate 2 being positioned at housing upper end, one deck insulation spacer 3 is provided with in cover plate 2, this insulation spacer has an annular boss 4, forms a cannelure 5, see Fig. 2 between this annular boss 4 and cover plate 1 inward flange.The width of cannelure 5 is less than the thickness of housing 1 upper end, and the upper end of housing 1 is sealed in cannelure 5.
