An electrical feedthrough connector to a low pressure (vacuum) chamber such as in a mass spectrometer comprises an epoxy body having at least two generally cylindrical portions with a step between the two generally cylindrical portions and with the portions mating with circular openings in the housing for the low pressure chamber. A step between the two cylindrical portions of the electrically insulating body mates with a step in the opening in the chamber housing with a gasket such as an o-ring placed between the steps to provide a pressure seal. A rigid printed circuit board with electrical components for an interconnect circuit is affixed to one end of the electrically insulating body with a flexible printed circuit connector extending from the rigid printed circuit board through the epoxy body to the low pressure chamber for interconnecting components within the chamber. The flexible printed circuit board is preferably spaced from the rigid printed circuit board and aligned perpendicular to the rigid printed circuit board thereby eliminating any possible leaks.
An electrical feedthrough connector to a low pressure chamber, said chamber being within a housing having a circular opening with at least two generally cylindrical opening portions of different diameters and a step between the two opening portions, said connector comprising:
