摘要： The disclosure concerns electron tubes. A tube such as a cathode-ray tube consists of several parts, namely the stem, the neck, the cone and the screen of the front face. To build a tube such as this more compactly while, at the same time, improving the quality of the fabrication, a new construction of the neck is proposed. In the prior art, the neck is a glass tube to which there is soldered a glass stem through which pass the connection terminals towards the various electrodes, internal to the tube. Here, the neck is built in the form of a stack of alternating metallic rings and ceramic rings. The metallic rings are used for the supporting of and electrical connection to the internal electrodes. The ceramic rings are used to insulate the metallic rings. The brazings between metallic rings and ceramic rings provide for vacuum tightness. The base of the tube is a ceramic washer without drillings other than lateral ones for the connections to pass through. The connections are made chiefly around the neck on the metallic rings.
