Connection area between housing parts of a vacuum interrupter, and a vacuum interrupter having a connection area of this type

摘要

The aim of the invention is to optimize, in vacuum interrupters, the connection area (12, 13, 14) between housing parts (2, 3, 4, 5), which are coaxially assigned to one another, with regard to the complexity of production for centering measures and with regard to the execution of the soldering process. To this end, a ring-like discoidal centering means (15) is used, which is made of a silver-coated copper and which comprises centering lugs (18) located on a tubular flange (17) that is arranged on the inner periphery of the centering means. Said centering lugs extend in an axial direction of the coaxial assignment and are provided in the form of tabs that point toward the ring-like discoidal area (24) of the centering means. The centering means is thereby overlapped by a tubular copper part, which is joined to the centering means and which serves as a shielding (10) inside the vacuum interrupter.
