[0002] Aluminum electrolytic capacitors have the characteristics of high voltage, small size and small capacity. Aluminum electrolytic capacitors are often used in coupling and decoupling circuits to provide signal transmission and isolation between different circuits. In circuits such as amplifiers and filters, they can transmit the AC component of the signal while blocking the DC current. Aluminum electrolytic capacitors can store electrical energy and release it when needed. It can be used as a backup power supply to meet sudden power needs or when power is interrupted.

[0003] In the production process of aluminum electrolytic capacitors, in order to ensure the quality, performance and reliability of aluminum electrolytic capacitors, it is usually necessary to detect potential problems such as short circuit, uncharged, surge, leakage, ESR, capacity and loss in aluminum electrolytic capacitors;

[0004] Currently, during the quality inspection process of aluminum electrolytic capacitors, although potential problems such as short circuits, non-charging, surges, leakage, ESR, capacity, and loss can be detected, these inspections are not followed by testing for implosion of the aluminum electrolytic capacitors.

In the worst case, they may fail when installed in the equipment, or even catch fire, posing a certain safety hazard. To this end, we propose a device for detecting implosion of aluminum electrolytic capacitors. Utility Model Content
