Anti-vibration aluminum electrolytic capacitor

Abstract

The invention is an anti-vibration aluminum electrolytic capacitor. The aluminum electrolytic capacitor body is arranged in an anti-vibration shell. A spring is arranged between a baffle at the bottomof the aluminum electrolytic capacitor body and the top plate of the anti-vibration shell. The top center of the anti-vibration shell is provided with threaded hole. A screw block is installed in thethreaded hole. A spring is connected to the lower part of the screw block, and supports the top center of the aluminum electrolytic capacitor body. The aluminum electrolytic capacitor is fixed by thelimitation of the spring, so that in the process of vibration, the spring can effectively absorb the vibration and release the vibration reasonably and effectively, thereby reducing damage to the capacitor body.

Description

technical field [0001] The invention relates to capacitors in electronic components, in particular to an anti-vibration aluminum electrolytic capacitor. Background technique [0002] Aluminum electrolytic capacitors have the advantages of large capacity, but also have the defects of large leakage and poor stability. Generally, aluminum electrolytic capacitors are mostly used in power filtering or low frequency circuits. [0003] In some places that require high anti-vibration performance of capacitors, such as around automobile engines, high-power inverters, frequency converters, electric welding machines, etc., in order to improve the anti-vibration ability of capacitors, gel is usually poured into capacitors to prevent vibration , but it will affect the heat dissipation of the capacitor and reduce the ripple resistance of the capacitor. Just using a fixed form to achieve anti-vibration is not the best form of anti-vibration for aluminum electrolytic capacitors. The best ...
