PATENTANSPRUCH:PATENT CLAIM: Aus einem rechteckigen Blechstück durch Rollen hergestellter Abschirmzylinder für Verstärkerröhren, insbesondere für Allglasröhren, der eine Verlängerung enthält, die in eine zugehörige öffnung im Chassis, insbesondere in eine zur Befestigung der Röhrenfassung dienende Hohlniete, zur Herstellung einer elektrischen Verbindung mit dem Chassis einsteckbar ist, dadurch gekennzeichnet, daß an der einen zur Achsrichtung des Abschirmzylinders parallelen Seite des rechteckigen Bleches (Z), aus dem der oben und unten offene, an der Röhre federnd anliegende Abschirmzylinder gebogen ist, ein rechteckiges Stück (St) angeschnitten ist, welches in Achsrichtung des Zylinders über die Rechteckform übersteht, und daß das überstehende Stück zusammen mit dem benachbarten Teil des Zylinderbleches in an sich bekannter Weise zu einem die Verlängerung bildenden Stift zusammengerollt ist.A shielding cylinder for amplifier tubes, in particular for all-glass tubes, made from a rectangular piece of sheet metal by rolling, which contains an extension which can be inserted into an associated opening in the chassis, in particular into a hollow rivet used to fasten the tube socket, in order to establish an electrical connection with the chassis characterized in that on one side of the rectangular sheet (Z) parallel to the axial direction of the shielding cylinder, from which the shielding cylinder, which is open at the top and the bottom and resiliently resting on the tube, is bent, a rectangular piece (St) is cut which is in the axial direction of the cylinder protrudes beyond the rectangular shape, and that the protruding piece is rolled together with the adjacent part of the cylinder sheet in a manner known per se to form a pin forming the extension.
