Problems solved by technology

This kind of laminated metallized film capacitor has a defect. The position of the cut surface of the capacitor core and the insulation distance between the metallized electrodes of different potentials are only the thickness of the dielectric between the electrodes. The thickness is several microns to tens of microns, depending on the coating. The coating material on the cut surface is used to insulate and ensure the withstand voltage, and the withstand voltage of this cut surface will not be too high

Abstract

The invention discloses an electrode structure of a laminated metallic film capacitor, which comprises at least two laminated metallic films; a plurality of curved gap strips not covered with metal coatings and having certain width are also arranged along the sectional direction of a laminated metallic thin capacitor chip on each metallic film so as to partially or entirely isolate adjacent metal coating units; the middle of each curved gap strip is in a notch shape, and the two sides of the notch form a staggered shoulder shape; and the end point at the most concave part of one curved void strip of two adjacent curved void strips at least enters into the notch of another curved void strip. With the structure, the insulation distance between different potentials of metallic electrodes on the section of the capacitor section is enlarged, and the voltage withstanding capability of the section of the laminated metallic film capacitor can be increased.

Description

technical field [0001] The invention relates to electronic components, in particular to an electrode structure of a laminated metallized film capacitor. Background technique [0002] Film capacitor is a kind of capacitor. It is a capacitor with superior performance. It has the following main characteristics: non-polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and low dielectric loss. Due to the small size and large capacity of film capacitors, they 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, high-voltage full-film capacitors, etc. [0003] A structural form of film capacitors is made of a metallized film. The metallized film is composed of a thin layer of metal vacuum-evaporated on a plastic film, and t...
