At the same time, due to the limitations of the fixed hooks and rings, the aluminum electrolytic capacitor device and the shell are separated, which makes it inconvenient to disassemble, inspect and maintain the aluminum electrolytic capacitor device. Therefore, we propose an aluminum electrolytic capacitor with an anti-pressure layer structure to solve the above problems. Utility Model Content

[0015] In the utility model, the aluminum electrolytic capacitor with a pressure-proof layer structure can guide the aluminum electrolytic capacitor body and the terminal through two half clamping rings. When the aluminum electrolytic capacitor body needs to be disassembled for maintenance, the bolts can be unscrewed to separate the two ear plates.
