<p>A coaxial type connector has largely rectangular cross-sections, with an outer contact width that is much larger than its height. As a result, the impedance is lowest in primary sectors that extend between the inner contact (20) and top and bottom inside surfaces of the outer conductor (24), while the impedance is highest in secondary sectors that extend horizontally from the inner conductor to each side of the outer conductor. Applicant maintains a largely constant impedance at the primary sectors, while allowing changes in impedance at the secondary sectors as by cutouts (60, 160) in insulation at the secondary sectors for receiving retention tabs. As a result of the largely rectangular shape, the center contact can be formed of sheet metal of constant height and of a width that can vary to provide enlargements for retention and for mating at the front end of the connector, with minimal overall impedance change. <IMAGE></p> |
