ABSTRACT:
A coaxial test probe employs a flexible inner conductor that buckles upon the application of an axial load is housed within a conductive outer sheath. The inner probe includes an insulating spacer which forms a recess applied to the protruding end of the inner conductor, such that buckling occurs within recess. A plurality of adjacent probes are mounted on a test fixture at opposing angles to facilitate automatic interrogation of closely spaced contact pads.
