Description

A capacitor cover

Technical Field

The utility model relates to the technical field of cover plates, in particular to a capacitor cover plate.

Background Art

Capacitors are one of the electronic components used in large quantities in electronic equipment. They are widely used in circuits for DC isolation, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control. The voltage on a capacitor cannot change suddenly. Once it does, the capacitor will burn out and need to be repaired. Existing capacitors are usually connected to circuits through wires, and the connection process requires welding. In some cases where there are no welding conditions (such as power outages), repairs are difficult and the connection between the capacitor and the wire cannot be quickly achieved. In view of this technical defect, the applicant specially applied for this invention.
