SOLDER RING FOR PRODUCTION OF VACUUM TUBE AND METHOD FOR THE PRODUCTION OF SUCH A SOLDER RING AND OF A VACUUM TUBE

摘要

Solder ring (12) for joining two components (10, 11) of a vacuum tube, the solder ring (12) comprising a joining part that consists of solder material for forming an airtight joint between the two components. The solder ring (12) further comprises at least one centring part. The centring part has at least one first projection (14, 15) that extends on one side of the joining part essentially in an axial direction of the solder ring (12) and at least one second projection (13, 16) that extends in an opposing direction for centring the two components (10, 11) with respect to one another.
