  • Coaxial split-bead glass-to-metal seal for high frequency transmission line
    Patent number: 6816039
    Abstract: Support structure for high frequency coaxial transmission line. A conductive bead ring is split in two halves longitudinally, containing a relief for excess glass flow and provision for locking the halves together. A glass dielectric surrounds the center conductor, which is tapered from a first larger diameter to a second smaller diameter in the region of the glass dielectric. A fixture for forming the glass to metal seal uses dams to control the positioning of the glass with respect to the taper in the center conductor.
