Abstract (en)

[origin: WO2005022694A1] A device that provides for the passage of an electrical current through a wall of separation of rooms operating under even very different thermal, atmospheric conditions. The invention uses metal leads fitted with interference into one or more adjacent coaxial discs of plastic materials with high electrical, mechanical, thermal, chemical resistance to provide the electrical feedthroughs. An embodiment of the invention (Fig. 1) consists of electrical feedthroughs formed of one or more cylindrical metal leads (6) that have a short length with larger diameter which interferes with the corresponding hole of the discs of plastic material (5, 5'), thus ensuring the vacuum tightness. The discs (5, 5') are located between and pressed by two adjacent, coaxial metal rings (2, 3) rigidly connected to each other by sealing. Metal ring (2) is sealed to the wall and provides for the separation of the rooms and the passage of the electrical current- Components (4, 1) can be threaded at their outer surfaces to allow electrical connectors to be used.
