High density zero insertion force connector

Claim 1

A zero insertion force mother/daughter board circuit connector having very high contact density capabilities, said connector comprising: an elongated housing of rigid insulative material defining a mother circuit board receiving face and an oppositely directed daughter circuit board receiving face having an elongated aperture therein, said housing further defining an interior cavity; a daughter circuit board receiving member secured in said housing opposite and spaced from said aperture; a pair of contact assemblies mounted in said cavity in opposition on opposite sides of said daughter circuit board receiving member; a like pair of cam assemblies each mounted in said cavity between an outer wall thereof and a respective contact assembly, wherein each said contact assembly comprises first and second elongated insulative contact members each having a plurality of passages therein in parallel spaced rows, and a plurality of terminal strips each comprising a plurality of terminals fixed in parallel spaced relation on a web of insulative material, each said terminal having one end received in an aperture in each said insulative member; and means to actuate said cam assemblies to drive portions of said contact assemblies into engagement with a daughter circuit board received in said connector.
