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 proc
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.

1. A connection area between two housing parts of a vacuum interrupter assigned coaxially to each other, comprising:a first housing part having a hollow-cylindrical ceramic insulator which is connected at an end face to a second housing part; and a centering device placed onto the ceramic insulator
1. A connection area between two housing parts of a vacuum interrupter assigned coaxially to each other, comprising:a first housing part having a hollow-cylindrical ceramic insulator which is connected at an end face to a second housing part; and a centering device placed onto the ceramic insulator which is arranged between the first and second housing parts, which centering device is formed as an annular disk and has, on an inner periphery, a tubular flange protruding into the ceramic insulator and is provided with centering lugs, the centering lugs being formed as tabs extending in an axial direction of the coaxial assignment and pointing toward an annular disk-shaped region of the centering device, and wherein the centering device comprises a silver-coated copper part and is covered by tubular copper part serving within the vacuum interrupter as a shielding and is connected to the centering device. 2. The connection area as claimed in claim 1, wherein the second housing part is a metal cover, which is connected to the first housing part by means of blade soldering and is centered by means of a flange arranged on an outer periphery of the annular disk-like centering device and extends in the axial direction of the coaxial assignment, and the tubular flange is provided on the inner periphery of the annular disk-like centering device for centering the copper part serving as shielding and is provided with additional centering lugs which are formed as tabs.3. The connection area as claimed in claim 1, wherein the second housing part is a metal cover, which is connected to the first housing part by means of blade soldering, and the copper part which is connected to the centering device and serves as shielding is provided with a collar flanged in the form of a circular arc for centering of the cover.4. The connection area as claimed in claim 2, wherein the copper part serving as shielding is arranged in a suspended manner on the centering device.5. The connection area as claimed in claim 2, wherein the copper part serving as shielding is arranged in a standing manner on the metal cover.6. The connection area as claimed in claim 1, wherein the second housing part is a hollow-cylindrical ceramic insulator and the copper part serving as shielding forms a main shield of the vacuum interrupter, two annular disk-like centering devices being arranged symmetrically in relation to each other and the main shield bearing in a precisely fitting manner against the tubular flanges of the two centering devices and resting on one tubular flange by means of an annular shoulder.7. A vacuum interrupter with a housing which surrounds a contact arrangement, comprising:a hollow-cylindrical housing part; two cover parts coaxially assigned to the housing part, the hollow-cylindrical housing part having at least one ceramic insulator and the cover parts being penetrated by connection pins leading to the contact arrangement; at least one cover part connected to the hollow-cylindrical housing part by means of blade soldering; and at least one shielding arranged inside the housing, where a connection area is formed by blade soldering and the connection area comprises a centering device placed onto the at least one ceramic insulator which is arranged between the first and second housing parts, which centering device is formed as an annular disk and has, on an inner periphery, a tubular flange protruding into the ceramic insulator and is provided with centering lugs, the centering lugs being formed as tabs extending in an axial direction of the coaxial assignment and pointing toward an annular disk-shaped region of the centering device, and wherein the centering device comprises a silver-coated copper part and is covered by a tubular copper part serving within the vacuum interrupter as a shielding and is connected to the centering device. 8. The vacuum interrupter as claimed in claim 7, wherein the connection area has a copper part serving as shielding and is arranged in a suspended manner on the centering device.9. The vacuum interrupter as claimed in claim 8, wherein an additional connection area has a copper part serving as shielding and is arranged in a standing manner on the metal cover.10. The vacuum interrupter as claimed in claim 7, wherein the hollow-cylindrical housing part has at least two ceramic insulators arranged coaxially in relation to each other and is formed in the connection area, wherein one of the housing parts is a hollow-cylindrical ceramic insulator and a copper part serving as shielding forms a main shield of the vacuum interrupter, two annular substantially disk shaped centering devices being arranged symmetrically in relation to each other and a main shield bearing in a precisely fitting manner against tubular flanges of the two centering devices and resting on one tubular flange by means of an annular shoulder.
