  • Electrolytic capacitor case design with insert molded elastomer seals
    Patent number: 7696002
    Abstract: Disclosed herein is a method for manufacturing a feed thru for use in an electrolytic capacitor case. First, an electrode is inserted into a liquid injection mold. Liquid elastomer is then injected into the mold to surround a portion of the electrode. The elastomer is cured, and the resulting electrode and feed thru combination is inserted into a machined hole in a capacitor case. The machined hole may be located on either the base or the lid of the capacitor case. In other embodiments, a ferrule may also be placed in the liquid injection mold prior to injecting liquid elastomer. When a ferrule is used, the assembly may be welded into a machined hole in a capacitor case.
