Magnetron having improved interconnecting anode vanes

摘要

A magnetron comprises an anode having an inner cylindrical wall and a plurality of copper vanes extending inwardly from the inner cylindrical wall, each vane having a notch in the top and bottom edges thereof. Each notch has an inner side edge, an outer side edge and a bottom edge. Inner and outer ring straps made of metal having a larger tensile strength than the vanes are placed in the notches. The inner ring strap is fixed to the inner side edge of alternative vanes. The inner side edge also has a slanting edge between the connection of the inner ring strap and the bottom edge to prevent cracking.
