Abstract

Disclosed is a device to make electrical contact to pins on an electronic module assembly. The connector receives the module pins without offering any resistance to insertion; hence this is a zero insertion force socket.

Tube on Cantilever Spring Zero Insertion Force Socket

      Disclosed is a device to make electrical contact to pins on an
electronic module assembly.  The connector receives the module pins
without offering any resistance to insertion; hence this is a zero
insertion force socket.

      An array of TUBE/SPRING assemblies are permanently affixed to
the BOTTOM PLATE (Fig. 1, one sample shown).  Each TUBE/SPRING
assembly is electrically independent of the others.  Electrical
connection is made to each TUBE/SPRING assembly through its
connection to the BOTTOM PLATE.

      The device is prepared to receive the module by moving the TOP
PLATE towards the bottom plate and deflecting the TUBE/SPRING
assemblies (Fig. 2).  This straightens the CONTACT TUBES and aligns
them under the openings in the TOP PLATE.  Movement of the top plate
can be achieved through any capable means.  After insertion of the
module, the TOP PLATE is released (Fig. 3).  Each SPRING causes its
adjoining CONTACT TUBE to move and rotate slightly.  Two points on
the CONTACT TUBE thereby seat firmly against the electronic module
pin with a biting action.  The action of moving the TOP PLATE towards
the bottom plate can be repeated for multiple insertion and removal
cycles.
