CONNECTION ZONE BETWEEN HOUSING PARTS OF A VACUUM SWITCHING TUBE AND VACUUM SWITCHING TUBE HAVING SUCH A CONNECTION ZONE

摘要

P Connection zone between two housing parts coaxially associated with each other of a vacuum switching tube, in which one of the housing parts is a hollow cylindrical ceramic insulator (2), which is connected on the front side to the other housing part (4), and in which it is interposed between the two housing parts a centering means (15) applied to the ceramic insulator and constituted in the form of A centering means (15) comprises on the inner periphery a flange penetrating into the ceramic insulator and provided with centering spouts (18), the centering spouts being in the form of tongues (18) extending in the axial direction of the coaxial association and facing the annular washer-shaped part of the centering means. /P
