ABSTRACT:
A thin, board-to-board zero force insertion and withdrawal connector having a housing containing a plurality of contacts with a first end portion of the contacts secured therein. A pair of parallel rows of rib-like elements extend along the length of the housing and define a U-shaped slot into which the edge of a circuit board can be inserted. The ribs form grooves therebetween which are perpendicular to the rows of ribs. The other end portion of each of said contacts extends downwardly into a groove towards the inner sides of said rib-like elements defining a side of said U-shaped slot, and then further extends upwardly towards the outer side of said rib-like elements. A plate is positioned along the length of said housing and secured thereto by a flexible hinge which divides the plate longitudinally along its length into two sections. A first of these sections extends over the said other end portions of said contacts. The other section of said plate has inclined planes formed on the inner surfaces thereof. A flat strip of material, which also has inclined planes on one surface thereof, fits in-between said second section of said plate and said housing, with the inclined plane surfaces mated to each other. By moving the flat strip in a first direction the said plate is pivoted about its flexible hinge so that said first section thereof forces the said other end portions of said contacts down into said U-shaped slot and against the edge of a circuit board inserted therein.
