AI Technical Summary
When the existing anti-interference metallized film box capacitors reach their service life, they lack structural reminders that specify the time. When replacing, they need to perform soldering operations, which is relatively inconvenient to use.
An anti-interference metallized film box capacitor is designed. By setting a plastic film on the top surface of the capacitor body, the aging life is the same as that of the capacitor body. When the plastic film ages and is blasted by the shrapnel, you can judge the end of the capacitor's life by observing its integrity. In addition, the connection between the capacitor body and the base adopts a shrapnel and annular groove structure, simplifying the replacement process and ensuring circuit connectivity through the design of the conductive ring and reed.
By observing the integrity of the plastic film, the end of the capacitor life can be accurately judged, the problem of no specific indication time is solved, and the inconvenience of solder operation is avoided through the simplified replacement structure, ensuring the circuit connectivity and good contact.
