Manufacturing method of the vacuum tube and solder ring and take vacuum tube manufacturing solder ring

摘要

Solder ring for joining two components of a vacuum tube (10, 11) (12) has a joint portion of the solder material forming an airtight joint between the components of the two. Furthermore, the solder ring (12) has a centering portion of at least one. Alignment part, the second protrusion of the at least one first protrusion and one (14, 15) extending in opposite directions, at least extending in the axial direction (12) ring the solder on the surface of one of the junction and a (13, 16), two components (10, 11) is centered by these parts.
