Shock-resistant ox horn aluminium electrolytic capacitor

Abstract

The invention provides a shock-resistant ox horn aluminium electrolytic capacitor. The aluminium electrolytic capacitor comprises an aluminium shell, a core, packaging terminals and a conductive foil connected with the core and the packaging terminals; the ox horn aluminium electrolytic capacitor also comprises a top ejecting pin bracket and a bottom ejecting pin bracket arranged on the top and the bottom of the core respectively; the top ejecting pin bracket comprises a first ejecting pin and a first limiting part; the bottom ejecting pin bracket comprises a second ejecting pin and a second limiting part; through holes are formed in the internal center of the core; the first ejecting pin and the second ejecting pin are inserted in the through holes and laminated with the inner sides of the through holes; the first limiting part is laminated with the inner surface of the aluminium shell; the inner side of the second limiting part is laminated with the outer surface of the core; and the outer side of the second limiting part is laminated with the inner surface of the aluminium shell. According to the scheme, the core can be firmly fixed in the aluminium shell, so that the capacitor failure caused by an open circuit due to repeat folding of the conductive coil can be avoided.

Description

technical field [0001] The invention relates to an aluminum electrolytic capacitor, in particular to an anti-shock type horn aluminum electrolytic capacitor. Background technique [0002] Horn aluminum electrolytic capacitors installed under vibrating equipment such as audio, automobiles, and working equipment are assembled on the circuit board through the terminals of the horn aluminum electrolytic capacitor. The aluminum shell of the capacitor will not vibrate with the vibration of the equipment, but the core of the horn aluminum electrolytic capacitor The core and the packaging terminal are connected by conductive foil, and the core of the horn aluminum electrolytic capacitor will vibrate with the vibration of the above equipment, causing the conductive foil connected between the core and the packaging terminal to be easily folded repeatedly, resulting in cracks or breaks, thus forming In an open circuit condition, the capacitor fails. [0003] At present, the fixation o...

AI Technical Summary

Problems solved by technology

Therefore, the CN201893241U patent cannot solve the core vibration inside the aluminum shell, and adding a shell outside the capacitor is not conducive to heat dissipation

[0005] It can be seen that the current horn-type aluminum electrolytic capacitors have not yet solved the shockproof characteristics.
