Abstract

Die Einrichtung zur Abdichtung und Befestigung von Heizleitern (1) an elektrisch beheizten Vakuumöfen nach der Erfindung weist einen mit einer Isolierhülse (5) versehenen Heizleiter (1) auf, der mit Hilfe einer Führungshülse (3), in der Heizleiter (1) mit Isolierhülse (5) geführt sind, lösbar mit der Wand (2) des Vakuumofen-Gefäßes verbunden ist. Zwischen Isolierhülse (5) und Heizleiter (1) und zwischen Führungshülse (3) und Ofengefäßwand (2) sind Dichtungen (9, 4) angeordnet, die durch Verformen beim Verschieben der Isolierhülse (5) bzw. Anziehen der Führungshülse (3) an die Ofengefäßwand ihre volle Dichtwirkung erzielen. The device for sealing and fastening Heating conductors (1) on electrically heated vacuum ovens The invention has an insulation sleeve (5) provided heating conductor (1), with the help of a Guide sleeve (3) in the heating conductor (1) with Insulating sleeve (5) are guided, detachable with the wall (2) of the vacuum furnace vessel is connected. Between Insulating sleeve (5) and heating conductor (1) and between The guide sleeve (3) and furnace wall (2) are seals (9, 4) arranged by deforming when moving the insulating sleeve (5) or tightening the guide sleeve (3) their full sealing effect on the furnace wall achieve.
