Abstract
The coaxial connector disclosed herein accommodates differential expansion between inner and outer conductors in a multi-section run of coaxial transmission line by utilizing a coupler assembly which connects adjacent inner conductors, one of the inner conductors being fixedly connected to the coupler with axial movement being permitted with respect to the other inner conductor. Electrical connection between the coupler and the movable conductor is established at a single axial position by an annular conductive spring member while longitudinal alignment is maintained over the rest of the length of the coupler by insulating rings set into annular grooves. A tubular shield extends from the coupler over the adjacent end of the movable inner conductor without electrical contact. The axial length of the shield is larger than the differential expansion which occurs between inner and outer conductor sections. The shield masks the gap at end of the movable inner conductor which is otherwise variable with differential expansion and thereby minimizes the changes in impedance at the connector.
