High-voltage electrode structure used for ionic pump

Abstract

The invention relates to the field of ultrahigh frequency vacuum electron devices, and discloses a high-voltage electrode structure used for an ionic pump. The high-voltage electrode structure comprises a grounding connecting cylinder and a standard high-voltage joint. The inner wall of one end of the grounding connecting cylinder is provided with internal threads cooperated with an ionic pump screwed joint. A connecting conductor end of the standard high-voltage joint is welded with a high-voltage terminal inner conductor. The outer periphery of the end of the high-voltage terminal inner conductor is provided with external threads cooperated with a binding post screw hole on the end of the ionic pump screwed joint. The standard high-voltage joint and the other end of the grounding connecting cylinder are in interference fit. The high-voltage electrode structure used for an ionic pump is firm in connection, good in security, simple in structure, and easy in processing and assembling.

Description

technical field [0001] The invention relates to the field of ultra-high-frequency vacuum electronic devices, in particular to a high-voltage electrode structure for an ion pump. Background technique [0002] The ion pump needs DC high voltage when it works, and its life is directly related to the quality of the power supply. Therefore, the ion pump not only has high requirements on the performance parameters of the ion pump power supply, but also has high requirements on the connection method with the ion pump power supply. Now In technology, there are two main ways to connect the ion pump and the ion pump power supply: [0003] 1. One is to clamp the connectors of the two electrodes of the ion pump power supply to the two electrodes of the ion pump respectively, but this connection method is poor in firmness and safety; [0004] 2. The second is to install a power socket box outside the ion pump, connect the positive and negative poles of the ion pump to the socket of the ...
