Integrated welding structure with ceramic ring and anode of medium-sized electron tube

Abstract

A medium-sized electron tube anode integrated welding structure with a ceramic ring comprises an anode, a fixing ring, a radiating fin and an anode ceramic ring, the radiating fin is fixed on the outer surface of the anode, and the medium-sized electron tube anode integrated welding structure with the ceramic ring is characterized in that an anode port is in a step shape, and the fixing ring comprises a straight section and a side flange perpendicular to the straight section. The straight section of the fixing ring is sleeved on the step of the anode port, the side turnup edge of the fixing ring is attached to the end face of the port of the anode ceramic ring, the radiating fin and the anode are integrally brazed and formed, and the fixing ring, the anode and the anode ceramic ring are integrally brazed and formed. The utility model has the beneficial effects that the radiating fin and the anode, the fixing ring and the anode as well as the fixing ring and the anode ceramic ring are integrally brazed and formed, so that the finished product quality and the braze welding air tightness are improved, and the stress of parts is far smaller than that of argon arc welding; the distance between the anode fixing ring and the grid lead-out ring is increased, the voltage resistance is improved, manpower is saved due to integral forming, the production efficiency is improved, and the energy loss is reduced.
