Abstract

The application discloses a plug-in high-voltage thin film capacitor, which comprises an aluminum shell, a capacitor core is arranged in the aluminum shell, a conductive plug is electrically connected with the capacitor core, one end of the conductive plug is fixed to the end of the aluminum shell, and the conductive plug can be connected with an external circuit; and an insulating top cover which comprises a fixed part and a supporting part connected with each other, the fixed part is sleeved on the end of the aluminum shell, and the other end of the conductive plug is located in the inside of the supporting part after penetrating through the fixed part. Since the conductive plug can be connected with the external circuit, the capacitor is arranged in a plug-in structure through the arrangement of the conductive plug, the capacitor can be installed by hand plugging, the capacitor is convenient and fast to install and replace, and the installation and maintenance efficiency of the capacitor is improved. Since the insulating top cover is arranged, support is provided through the supporting part during plugging and using, the conductive plug is prevented from being damaged during plugging and using, and the conductive plug is prevented from being damaged during plugging and using.
