Abstract
An encapsulated electrical capacitor in which an end and a major portion of the cylindrical outer shell of the capacitor is positioned within a cup-shaped sleeve before an outer housing is molded around the capacitor and sleeve. The sleeve has axially extending internal ribs which stiffen its outer annular wall to thereby help to prevent damage to the capacitor from hydraulic forces during the encapsulating process. The internal ribs also define insulating air spaces between one another, and this helps to reduce thermal conduction into the capacitor during the molding process. The outer housing is preferably formed from polypropylene, and the sleeve is preferably formed from a material which will retain a major portion of its strength and rigidity at the molding temperature of the outer housing, for example, a polyester material when the outer housing is formed from polypropylene.
