Abstract
A connecting joint for a radio frequency waveguide line comprises a tubular metallic braid wire shield connecting two beam line pipe ends thereby making the inside surface appear as a continuous beam tube. The metallic braid wire is secured within a bellows assembly that allows the connecting joint to expand or contract as is appropriate for changes in ambient conditions or conditions within the waveguide line. The connecting joint is capable of supporting either positive or negative pressure within the joint while the exterior of the joint may vary with ambient conditions.
