Problems solved by technology

[0003] The laminated aluminum solid capacitors currently used in the market have poor heat resistance during work and use, and long-term work will generate heat accumulation, accelerate the aging of the capacitor, reduce the service life of the capacitor, and the compressive performance is also poor. Low, and the traditional laminated aluminum solid capacitors are easily corroded by humid gas, resulting in poor insulation of the capacitor and reducing the safety of use

Abstract

The invention discloses a high-temperature-resistant and high-humidity-resistant laminated aluminum solid-state capacitor and a preparation method thereof. The capacitor comprises a shell with a containing space, wherein an inner core is fixedly arranged in the containing space of the shell, the inner core is fixedly connected with a negative guide pin and a positive guide pin, the sides, away from the inner core, of the negative guide pin and the positive guide pin penetrate through the shell and are located on the outer side of the shell, a moisture-proof layer and a high-temperature-resistant layer are sequentially arranged between the inner core and the inner wall of the shell from inside to outside, the side, close to the high-temperature-resistant layer, of the moisture-proof layer extends outwards to form a plurality of evenly-distributed buffer columns, a plurality of evenly-distributed buffer grooves are formed in the high-temperature-resistant layer, rubber is further fixedlyarranged in the shell, and the rubber is located on one side of the negative guide pin of the inner core. The laminated aluminum solid-state capacitor prepared by the invention has good high-temperature and high-humidity resistance.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a high temperature and high humidity resistant laminated aluminum solid capacitor and a preparation method thereof. Background technique [0002] A capacitor is made up of two electrodes with a dielectric material between them. The dielectric material is a kind of dielectric. When it is placed in the electric field between two parallel plates with equal opposite charges, polarized charges are generated on the surface of the medium due to polarization, so that the charges bound on the plates The corresponding increase keeps the potential difference between the plates unchanged. [0003] The laminated aluminum solid capacitors currently used in the market have poor heat resistance during work and use, and long-term work will generate heat accumulation, accelerate the aging of the capacitor, reduce the service life of the capacitor, and the compressive performance is also poor. ...
