Combined thin-film capacitor for electric automobile charging pile

Abstract

The invention relates to the technical field of capacitors, provides a combined thin-film capacitor for an electric vehicle charging pile, and aims to solve the problems that a traditional combined capacitor is simple in structure, a plurality of combined capacitors are simply combined in parallel or in series, arrangement and integration are difficult, a plurality of combined capacitors are closeto each other and stacked, the heat dissipation effect is poor, and burnout risks exist. The capacitor comprises an outer shell with an opening in the upper end, an outer cover plate is installed atthe opening in the upper end of the outer shell, two main wiring terminals are vertically inserted into the outer cover plate, the side wall of the outer shell is of a polyhedron structure, and the outer shell comprises a plurality of shell body parts distributed in an annular array mode and a plurality of bevel edge parts connected with the shell body parts; a hollow boss is arranged in the middle of an inner cavity of the outer shell, and a plurality of branch capacitor units are distributed between the hollow boss and the shell body part. The capacitor is especially suitable for charging and discharging of the electric vehicle charging pile, and has high social use value and application prospect.

Description

Technical field [0001] The present invention relates to the field of capacitors, and more particularly to a combined thin film capacitor for electric vehicle charging piles. Background technique [0002] Capacitors are one of the electronic components used in electronic devices, which are widely used in circuitry, coupling, bypass, filtering, tuning loop, energy conversion, control, etc. in circuits. Capacitors, usually referred to as their ability to accommodate charges. Usually defined the capacitor is the 'power-charged container', which is a device that accommodates charge. [0003] The combined capacitor enables a combination of multiple capacitors to improve a function of the capacitor, the conventional combined capacitor structure is simple, but simply performs multiple parallel or series combination, integration, and more close stacks , Heat dissipation effect, risk of burning, cannot meet the use of modern electrical components. [0004] The disclosure is the patent of C...
