Problems solved by technology

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. Due to the cumulative error of each part, the spacing and concentric error between the anodes will increase

Abstract

First anode is connected to one end of ceramic insulation sect module. The other end of the ceramic insulation sect module is connected to a terminal port of a transition sect module, which is connected to second anode. First anode seat is installed on the first anode, and a featheredge area as a soldering edge is setup at tail part of the first anode. There is a lamellar soldering edge between same terminal ports of first anode seat and the tail part of the first anode. Assembling procedure includes steps: inserting die in to second anode; placing the transition sect module, the ceramic insulation sect module, first anode, and first anode seat; inner diameter of first anode head sheathed on up end of the die; being placed to first anode, tool bar impresses force downward; then, soldering two modules, first anode, and first anode seat as integrated module; taking die out and replacing second anode back to original position; soldering second anode and transition sect module.

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...
