Abstract
A double-ended, coaxial contact assembly has a center probe rod (12) mounted in the bore of a dielectric center spacer bushing (16) and mounts a probe contact assembly on each end of the center probe rod. The center probe rod is received in a ground sleeve (19) with the probe contact assemblies maintained in coaxial relationship with the ground sleeve by a dielectric outer spacer bushing (17). In certain embodiments a movable ground plunger (18g,22) is slidably received in each end of the ground sleeves and biased outwardly by respective ground plunger coil springs (25). In one such embodiment the center spacer bushing (16′) is provided with an axially extending sleeve disposed between the respective probe contact assembly and the ground sleeve.
