Tini-Probe Interposer Connector

      Disclosed is a matrix connector incorporating a variety of
specially configured buckling-column contacts contained in cavities
within a split housing, said contacts designed to buckle at
near-constant force while achieving definitive contact wipe and
compensating for contact deflection variability.

      As shown in the Figure which reflects a half-view of the
interposer connector about symmetry plane 5, contacts are designed
each with an initially curved lateral section 1 and transverse
section 2, these sections being contained within housing cavities 6
and 4, respectively.  Transverse section 2 can be initially
backwardly-formed, that is, opposing the direction of contact
buckling 8.  The active contact section 7 initially extends a
predetermined amount above the housing surfaces.  The cross-section
of section 1 and its' length are selected to achieve the desired
buckling characteristics, the rectangular-section embodiment shown
being typical.

      The interposer connector is sandwiched between two planar
surfaces, each having a matrix array of directly opposing metallic
pads to be interconnected.  As these planar surfaces are made to
approach each other, they impose increasing deflection 9 on the
contacts.  As this occurs, contact section 7 rotates thereby
achieving contact wipe and contact section 1 buckles within cavity 6
and in the direction of initial curvature thereby achieving a
near-constant normal force. ...
