AI Technical Summary

Technical Problem

Large-capacity aluminum electrolytic capacitors have problems with insufficient structural strength and poor compressive strength, and are prone to deform when subjected to extrusion or impact, resulting in leakage of the electrolyte and affecting service life.

Method used

A compressive-resistant aluminum electrolytic capacitor is designed, adopting a protective cover structure, including a bottom plate, a top plate and a rubber sleeve. A distribution rod and a driving block are provided in the rubber sleeve. The driving block drives the movement of the distribution rod, and the extrusion pressure is converted into a movement tendency of the bottom plate and the top plate to separate from each other, reducing the extrusion pressure on the capacitor body.

Benefits of technology

It effectively improves the compressive resistance of aluminum electrolytic capacitors, prevents the capacitor from deformation and leakage of electrolyte due to extrusion, extends the service life, and reduces the possibility of distribution rod bending and damage.
