AI Technical Summary

Problems solved by technology

[0003] The capacitor is composed of two electrodes and the electrolyte material between them. When packaging the capacitor, before the filling material is solidified or after being heated, it will cause leakage due to poor sealing performance of the shell, which is not convenient for packaging operation. The packaging operation at the electrode is even more troublesome, because the lead-out electrode is not fixed, and if the installation is not careful, it is easy to damage the connection of the lead-out electrode, causing the electrode to fall off. When the capacitor fails, the capacitor core will heat up rapidly, making the internal pressure of the capacitor large. Cause capacitor explosion, lead to capacitor damage, equipment maintenance costs are extremely high
