Abstract
In an electrolytic capacitor, there is provided an improved header for closing the open end of a capacitor can. The header includes a rigid insulating or metal body having at least one terminal passing therethrough, and a resilient elastomeric cover having inner and side walls molded about respective surfaces of the body and a tubular terminal sealing portion molded interiorly about a hole in the body through which the terminal passes. The tubular portion has formed at its inner annular wall a plurality of axially spaced apart annular sealing beads which annularly engage the terminal with compressive force to effect respective axially spaced apart line seals. When assembled under compression between axially spaced components of the can, the inner and side walls of the cover cooperate with such components to provide plural seals against leakage of electrolyte from the can about the rigid body while the tubular portion seals against leakage at the terminal. The cover, being inert and impervious to the electrolyte, further serves to isolate the rigid body from the electrolyte to preclude electrolyte loss and contamination. Also provided is a small annular flapper bead which further seals the end cap to the capacitor can when subjected to internal pressure in the can as well as by its own resilient action.
