Anti-vibration laminated solid aluminum electrolytic capacitor and manufacturing method thereof

Abstract

An anti-vibration laminated solid aluminum electrolytic capacitor comprises a sealing assembly and a core fixedly arranged in the sealing assembly, the core is electrically connected with a positive guide pin and a negative guide pin, and the positive guide pin and the negative guide pin penetrate out of the sealing assembly; the core is composed of a plurality of stacked single sheets, and each single sheet comprises a positive electrode end, a negative electrode end and a shielding glue wire located between the positive electrode end and the negative electrode end; the positive electrode end of the single sheet is provided with a positive electrode fixing terminal, the positive electrode guide pin is connected with the positive electrode fixing terminal, the negative electrode end of the single sheet is provided with a negative electrode fixing terminal, and the negative electrode guide pin is connected with the negative electrode fixing terminal. The positive electrode fixing terminal and the negative electrode fixing terminal are adopted to fix the positive electrode ends and the negative electrode ends of the stacked single sheets respectively, the stacked single sheets can be effectively prevented from loosening due to the influence of the external environment in the assembling process of the capacitor and the using process of the capacitor, and therefore the electrical performance of the capacitor is stable.

Description

technical field [0001] The invention relates to the technical field of solid aluminum electrolytic capacitors, in particular to an anti-seismic laminated solid aluminum electrolytic capacitor and a manufacturing method thereof. Background technique [0002] The laminated solid aluminum electrolytic capacitor uses a solid conductive polymer with high conductivity to replace the liquid electrolyte in the traditional capacitor, and uses a laminated method to connect the single pieces that make up the core of the laminated solid aluminum electrolytic capacitor in parallel. Compared with liquid aluminum electrolytic capacitors, laminated solid aluminum electrolytic capacitors have many advantages such as smaller volume, smaller equivalent series resistance (ESR), wide temperature range, environmental protection and long life, and meet the requirements of miniaturization and high frequency of electronic products. Development trend to meet surface mount technology (SMT) requirement...

AI Technical Summary

Problems solved by technology

[0003] Since the core of a laminated solid aluminum electrolytic capacitor is formed by stacking monoliths together, this means that during the assembly process of the capacitor and the use of the capacitor, due to external influences, the monoliths that make up the core may be damaged. Looseness occurs, resulting in unstable electrical properties of the product
