Electrovacuum tube with dual anodes, and assembling method

Abstract

A double-anode electric vacuum tube, the first anode is connected to one end of the ceramic insulation section assembly, the other end of the ceramic insulation section assembly is connected to a port of the transition section assembly, and the transition section assembly is connected to the second anode; the first anode is equipped with The first anode seat is provided with a thin edge area as a welding edge at the tail of the first anode, and there is a sheet-shaped welding edge at the same port of the first anode seat and the tail of the first anode seat. When assembling, insert the mold into the second anode, put the transition section assembly, the ceramic insulation section assembly, the first anode and the first anode seat in sequence, wherein the inner diameter of the first anode head is sleeved on the upper end of the mould, and then place a tool Put the rod into the first anode to exert a vertical downward force, and weld the transition section assembly, the ceramic insulation section assembly, the first anode and the first anode seat together in the following order, and weld the second anode and the above welding together The components are separated, the second anode is placed back in place after the mold is taken out, and the connection between the second anode and the transition section component is welded.

Description

technical field [0001] The invention relates to a structure of an electric vacuum tube, in particular to a structure of a double-anode electric vacuum tube. [0002] The invention also relates to a method of assembling the above structure. Background technique [0003] The structure of the known electric vacuum double anode is that a ceramic insulating section assembly is arranged between the first anode assembly and the second anode assembly. In this known structure, the positioning of the two anodes includes the distance between the two anodes and the concentricity of the two anodes. The existing positioning method relies on the precise processing of each part to ensure the distance and concentricity between the two anodes. However, due to the cumulative error of each part, the spacing and concentric error between the anodes will increase. Contents of the invention [0004] The purpose of the present invention is to provide a structure of a double-anode electric vacuum...
