Abstract:

An expansion joint for connecting sections of waveguide includes a plurality of spacer discs mounted on a plurality of guide rods. The guide rods are rigidly affixed to a termination member. Washer type springs are employed between the individual spacer discs on the guide rods for controlling increases and decreases in the space between the discs and, hence, compensating for contraction and expansion, respectively, of the waveguide sections while maintaining a uniform electrical path through the joint. Additional spacer discs having various thicknesses are also employed to allow for a predetermined maximum initial length adjustment within a prescribed tolerance.
