PURPOSE: A coaxial-like connector is provided to comprises with low cost, to arrange cutouts in an insulator and a sideward extension in an inner contact without the increase of loss. CONSTITUTION: A coaxial type connector has largely rectangular cross-sections, with an outer contact width much larger than its length. 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 fro the inner conductor to each side of the outer conductor. A largely constant impedance is maintains at a 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 is formed of sheet metal of constant height and of a width that varies to provide enlargements for retention and for mating at the front end of the connector, with minimal overall impedance change.
