Capacitor with molded header including strengthening material

摘要

An electrolytic capacitor which may use dimethyl formamide as the electrolyte has a metal housing and a variable thickness molded glass or mineral filled plastic header having a bolster ring adjacent the peripheral edge of the header, major rib members molded on the header which cooperate with further retainer members located at the bottom of the capacitor housing to retain the housing in position, and radial and circumferential members located within said bolster ring on the under side of said header certain of which members are of smaller thickness than the bolster ring, and which further includes areas of relatively thin dimensions located betweeen said circumferential members and said bolster ring, and between said rib members and said circumferential members.
