Abstract

The invention discloses a metalized film used for s capacitor. The metalized film comprises a base film (1) and metal coatings. The metal coatings comprise a left end coating (2), a right end coating (3) and a middle coating (4) which are arranged at intervals. The left end coating extends towards the left end of the base film and covers the left end surface of the base film. The right end coating extends towards the right end of the base film and covers the right end surface of the base film. The left end coating and the right end coating are arranged on the same side of the base film. The middle coating is arranged on the other side of the base film. End surfaces, close to the middle part of the base film, of the left end coating and the right end coating are connected with the middle coating through metal wires (5) laid in the base film. The metalized film has the advantages that the metalized film is arranged in segments, the cost is saved, the utilization rate is improved, and the metalized film is arranged at two sides of the base film and can be flexibly combined with other metalized films for usage; in addition, the parts, covered by left end coating and the right end coating, of the base film is arc-shaped, so that the performance of the metalized film is stable, and the metalized film is high in dielectric strength and not liable to be broken down.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a metallized film for capacitors. Background technique [0002] Film capacitor is a capacitor with superior performance, which has the following main characteristics: non-polarity, high insulation resistance, excellent frequency characteristics, small dielectric loss, and small volume and large capacity. Therefore, film capacitors have a wide range of uses and can form different series of products, such as high specific energy storage capacitors, anti-electromagnetic interference capacitors, anti-radiation capacitors, safety film capacitors, long-life capacitors, high-reliability capacitors, and high-voltage full-film capacitors Wait. With the development of digital, high-frequency, multi-functional, and thin, light, small, and portable electronic machines, capacitors will inevitably develop in the direction of small size, excellent performance, and lower price.
