Microwave tuning screw assembly having positive shorting

摘要

A microwave tuning screw assembly mounted in an opening in a cavity or waveguide and providing positive shorting at an inner wall of the cavity or waveguide. A chuck section is disposed in the opening and has elastically deformable fingers. A tuning screw section is received within the fingers so that as the fingers are elastically deformed inwardly, they grip the tuning screw section and thus provide positive shorting from the inner wall through the chuck section to the tuning screw section.
