Abstract: A coaxial connector is disclosed for terminating a coaxial transmission line. The connector includes a tubular spring element, comprising a cylindrical body having a plurality of reversely formed leaf spring fingers annularly spaced, and projecting forwardly therefrom. The spring fingers are intended for positionment within a tubular plug shell, and are engaged and compressed upon insertion of a jack body therebetween for retaining and electrically contacting the jack body.

Abstract: A dielectric plug is disclosed for coaxial connectors, the plug having an axial bore extending therethrough, and comprising rearward disposed inner and outer concentric cylindrical portions, which are integrally joined to a forward tubular portion. The inner and outer cylindrical portions are radially spaced apart for impedance matching purposes. The radial spacing further provides the outer cylinder with a spring resiliency to facilitate press fit retention of the dielectric plug within a conductive connector shell. The inner concentric portion is likewise provided with resilient spring properties due to the radial spacing, to facilitate resilient receipt of a center contact therein. An outer flange at the rearward end of the dielectric plug is adapted for retaining the dielectric plug within a tubular spring element, as part of the coaxial connector assembly.
