HOCHFREQUENZKOAXIALVERBINDER MIT GLEICHER IMPEDANZ

摘要

A coaxial electrical connector, particularly suited for high frequency ''blind-mate'' connections, remotely located connections, multiple connector assemblies and quick connect-disconnect applications, having two mating plug halves (32, 34), each plug having an inner conductor (46, 75), an outer conductor (42, 44) and a dielectric spacer (68, 70) therebetween, the inner and outer conductor on each plug being of unequal lengths such that one projects beyond the other; the longer inner conductor from one plug and the longer outer conductor form the other plug being designed to overlap each other when the connector is first electrically connected and only partially engaged (Fig. 3), thereby defining an overlap region (54, 56, 58, 60); the inner and outer conductors being shaped and the dielectric material of the spacers being chosen such that along the axis of the partially engaged connector, particularly in the overlap region, the effective outer diameter of the inner conductor (''d'') and the effective inner diameter of the outer conductor (''D'') and the dielectric constant of the material therebetween (''E'') satisfy the equation: Z = 138 (E)<-1/2> log (D/d), where Z is the impedance and is substantially constant along the length of the connector as the plugs (32, 34) are moved from the first electrically connected, partially engaged position to the fully engaged position.
