Abstract
An RF expansion joint is presented herein for connecting first and second axially spaced tubular conductor sections, having opposed free ends, together as the sections expand and contract with temperature variations and for providing passage of RF energy at a desired operating frequency between the sections. The joint includes an insulator sleeve which is received by the first section with the sleeve having a passageway extending longitudinally therethrough. An electrically conductive stub having proximal and distal ends is mounted to the free end of the second conductor section and extends into the passageway of the sleeve so as to be slidably received thereby. The distal end of the stub extends beyond the sleeve sufficient that the distal end is spaced inwardly from the inner wall of the first conductor section presenting essentially an open circuit to passage of RF energy.
