Electrically conductive lead-through structure for supplying power to heating element in vacuum container, has sealing element arranged in auxiliary housing, to separate vacuum in interior space of housing relative to container

摘要

The electrically conductive lead-through structure (1) has auxiliary housing (7) with guide elements (5,6) that are inserted into vacuum container (2), to connect and disconnect auxiliary housing with vacuum container. A sealing element (8) for vacuum separation, is arranged in wall (18) of auxiliary housing, so as to separate vacuum in interior space of auxiliary housing with respect to the container, and to maintain both auxiliary housing and container in air-tight state.
