Abstract
An explosion-proof aluminum housing for an electrolytic condenser comprises a housing, wherein an explosion-proof groove is formed on the inner wall of the bottom of the housing and 6 reinforcing ribs are arranged between the explosion-proof groove and the inner sidewall of the housing. The explosion-proof aluminum housing for the electrolytic condenser provided by the utility model is characterized in that the explosion-proof groove may crack when the electrolytic capacitor is overloaded so that heat and high voltage can be released immediately; and simultaneously, as the reinforcing ribs are arranged between the explosion-proof groove and the inner side wall of the housing, the opening of the explosion-proof groove is limited in size and the safety is improved.
Description
Technical field
The utility model relates to the explosion-proof aluminum shell that a kind of electrolytic capacitor is used, and belongs to field of capacitor manufacture.
Background technology
Adopt the electrolytic capacitor of aluminum hull, the bottom strength of aluminum hull and heat dispersion directly affect normal operation and the useful life of electrolytic capacitor.At present, the aluminum casing bottom of electrolytic capacitor generally can have anti-explosion groove, when electrolytic capacitor expands because the reasons such as overload cause rapid rising of internal electrolyte solution temperature, the anti-explosion groove place can ftracture, and because pressure is crossed conference so that the anti-explosion groove opening is excessive, thereby cause core bag, chip in the aluminum hull to splash out, and then have influence on the operation of whole operating mode.Therefore how the anti-explosion groove of aluminum casing bottom is offered and is seemed particularly important.
Summary of the invention
In order to overcome the defective that exists in the prior art, the explosion-proof aluminum shell that the utility model provides a kind of electrolytic capacitor to use has good thermal diffusivity, fail safe.
For realizing above technical purpose, the utility model will adopt following technical scheme:
The explosion-proof aluminum shell that a kind of electrolytic capacitor is used comprises housing, is provided with explosion-proof groove in the bottom interior wall of described housing, is provided with 6 road reinforcements between the madial wall of described explosion-proof groove and housing.
Described explosion-proof groove is " Y " or " ten " type; The degree of depth of described explosion-proof groove is the 1/5-4/5 of described housing bottom thickness.
The thickness of described reinforcement is the 1/5-4/5 of described housing bottom thickness.Described 6 road reinforcements evenly distribute at the housing bottom of circle.
The explosion-proof aluminum shell that a kind of electrolytic capacitor that the utility model provides is used, when electrolytic capacitor transshipped, explosion-proof groove can ftracture, in time release heat and high pressure; Because be provided with reinforcement between the madial wall of described explosion-proof groove and housing, limited the openings of sizes of anti-explosion groove simultaneously, fail safe is improved.

Embodiment
The explosion-proof aluminum shell that a kind of electrolytic capacitor is used comprises housing 1, is provided with explosion-proof groove 2 in the bottom interior wall of described housing 1, is provided with 6 road reinforcements 3 between the madial wall of described explosion-proof groove 2 and housing 1.
Described explosion-proof groove 2 is " ten " type; Described 6 road reinforcements 3 evenly distribute at the housing bottom 1 of circle.0.5 millimeter of the bottom thickness of described housing 1, the degree of depth of described explosion-proof groove 2 are 0.25 millimeter, and the thickness of described reinforcement 3 is 0.15 millimeter.
The degree of depth of described explosion-proof groove 2 is the 1/5-4/5 of described housing 1 bottom thickness; The thickness of described reinforcement 3 is the 1/5-4/5 of described housing 1 bottom thickness.Described explosion-proof groove also can be " Y " type.
The explosion-proof aluminum shell that a kind of electrolytic capacitor of the present utility model is used has good thermal diffusivity, fail safe.
