ABSTRACT:
A vacuum tight electrical feedthru is disclosed for use where electrical leads must pass through the walls of a container in which a high vacuum must be maintained. It is useful in conjunction with infrared sensors, as well as for security, fire detection, rescue, night vision and medical applications. The feedthru includes a ceramic circuit ring with electrical traces deposited on one side. A ceramic seal ring partially covers the traces and is fired down to the main ceramic ring forming a hermetic seal. Metal rings are brazed to the seal ring and the ceramic circuit ring to allow welding to a housing. Spring loaded pads load a resilient pad onto the cables forcing gold plated dots to make contact to the pads on the ceramic circuit ring. This feedthru provides 180 conductors, 90 on each side. The ribbon cables are etched to expose the wires, which are then pressed on the gold dots.
