  • Discoid capacitor structure
    Patent number: 4673900
    Abstract: The invention provides a novel attachment for a discoid capacitor and the like to the inside of a tubular casing and to a central lead. An electrically insulating sealing element is positioned below the capacitor during assembly vertically into the casing. The element fits closely about the lead and is deformed into contact with the wall of the housing about the capacitor. The element thus forms a dam to contain solder and flux used to couple the capacitor to the lead and to the casing from above the capacitor so that the solder and flux cannot pass by the capacitor into undesirable locations below the capacitor.
