Abstract
There is described a hermetic coaxial cable particularly adapted to be produced in miniature form and having a completely solid cross section with a solid metal central conductor, a tubular metal outer conductor, and a continuous glass dielectric insulator therebetween.
Claims2
The method of fabricating coaxial cable having a solid metal central core and a tubular outer conductor and having a continuous glass dielectric insulator therebetween, comprising the steps of:
- sealing the lower end of a length of glass tubing;
- providing a preform by disposing within the hollow core of said glass tubing, metal particles having a melting temperature lower than the softening temperature of the glass tubing;
- providing a metal-filled glass filament by heating said preform in a furnace to melt the metal particles and soften the glass tubing;
- cooling said metal-filled glass filament to solidify said metal;
- and
- depositing a metal coating on said glass filament by passing said soft glass filament down through a metal coating cup.
