Abstract

A coaxial connector is provided, of a type that has a front portion (12) where the inner conductor (14) forms a socket for receiving a pin (M) of predetermined diameter (A) (1 mm) and the outer conductor has a front end of predetermined outside diameter (B) (3.7 mm), which enables an increase in characteristic impedance at the front portion of the connector to more closely match the impedance of the middle portion (16) of the connector. A dielectric support (30) that positions the inner conductor within the over one, includes primarily air at the front portion, to increase the characteristic impedance of the front portion without changing its diameter. The insulative support preferably includes a middle portion (72) with ring-shaped locating portions (62, 64) that are closely received in the outer conductor, that closely surround the inner conductor, and that abut shoulders on the inner conductor to fix the position of the inner conductor in radial and axial directions. The support also includes a front portion (66) with a ring-shaped locating portion (56) that is closely received within the front end (60) of the outer conductor but which does not engage the inner conductor and that forms a lead-in (58), and with posts (66) extending axially from the front ring to the middle portion of the support.
