Abstract
The utility model discloses an aluminum electrolytic capacitor including a core provided with a polarity outgoing line, a polarity outgoing line guide pin led from the core and a packaging metal shell wrapping the core. The bottom part of the packaging metal shell adopts an interlayer design. An anti-explosion gasket is arranged between the bottom part of the packaging metal shell and the bottom part of the core. Air channels are formed between the anti-explosion gasket and the bottom of the core and between anti-explosion gasket and the packaging metal shell. When the aluminum electrolytic capacitor is exploding, air flows are buffered through the air channels, so that impact caused by explosion is reduced and aluminum foils and paper scraps can be filtered effectively. Only steam can be released finally for decompression safely. No ejection of electric sparks may be caused and the aluminum electrolytic capacitor is safe and reliable.

Further, the corresponding core bag of described explosion-proof pad is arranged to the shape matching with core bag, and the center of explosion-proof pad is provided with aperture, with suitable with the volume heart circular hole of core bag.
Further, described explosion-proof pad is provided with groove and projection.
Further, described groove and projection are arranged at one side or the two sides of explosion-proof pad.
Further, two-sided described groove and the projection of being staggeredly equipped with of described explosion-proof pad, wherein, the groove in explosion-proof pad one side forms described projection in the corresponding position of another side.
Further, described package metals shell is aluminum hull; Described explosion-proof pad is that special type rafifinal is made.
Further, the rounded design of described core bag, the corresponding core bag of described explosion-proof pad is rounded.
In the embodiment of the present invention's creation, by to package metals outer casing bottom sandwich design, install explosion-proof pad additional, change the blast impulse route of aluminium electrolytic capacitor, flung path changing as " Z " type path by former taking point as outburst, the friction to aluminum pad and encapsulation aluminum hull sidewall is changed in the impact at broken end of making to explode, effectively weaken impact kinetic energy, effectively filter aluminium foil and the broken end of barrier paper, release pressure release that finally can safety only have steam gas, do not cause electric spark broken end ejection, safe and reliable.
