Abstract
An anchoring terminal is secured in an elastomer seal, which is under compression in an end of a sealed miniature electrolytic capacitor, by forcing the terminal less than all the way through the compressed seal. The anchoring terminal is positioned in the seal with respect to the active capacitor leads through the seal so that the anchoring terminal provides stability and ensures proper polarity for mounting the capacitor on a wiring board.
Claims4
A miniature electrolytic capacitor having a capacitor section housing in a can, wherein the improvement comprises the open end of said can being closed by an elastomer seal, said seal being held under compression within said open end by a circumferential groove in said can, at least one electrical lead from said capacitor section passing through said seal, and an anchor terminal being secured in said seal with one end of said anchor terminal extending outwardly from the outer surface of said seal and with the other end of said anchor terminal beyond said groove and stopping short of the inner surface of said seal.
