Background
The capacitor is a device for accommodating electric charges, is an electronic device which is used in electronic equipment in large quantity, and is widely applied to aspects of blocking direct current, alternating current, coupling, bypassing, filtering, tuning loop, energy conversion, control and the like in a circuit; the capacitor is composed of polar plates at two ends and an insulating dielectric medium in the middle, two conductors which are insulated from each other and closely spaced form a potential difference after being electrified, and when the voltage of the two conductors is increased to a certain degree, the breakdown voltage is reached. The capacitor is not an insulator. In order to assemble and convenient to use, the existing capacitor usually also has a metal shell and a cover plate, a conductor extends into the metal shell, the conductor is used for sealing the inside of the capacitor through the cover plate, the contact with the external environment is prevented, but because an electronic device generates heat easily, once the capacitor is heated to expand or is cooled to shrink, a gap can be formed between the cover plate and the metal shell, the capacitor cannot work in liquid because of poor sealing performance, the working environment is limited, the capacitor is not sealed, the capacitor is easy to damage, the service life is prolonged, meanwhile, the capacitor can only meet the working requirement in a rated range, and the instantaneous high-frequency voltage can easily cause the capacitor to be damaged along with the capacitor.
