LOW OR ZERO INSERTION FORCE CONNECTOR FOR MULTI-PIN ARRAYS

摘要

A connector for zero or low insertion force receipt of multi-pin arrays, such as those in very large scale integration (VLSI) components, includes cam surfaces for selective movement to oppose the self-biasing forces of connector contacts for pin insertion and reverse movement to permit the contacts to effect tight engagement with the pins under the influence of such self-biasing forces. The connector preferably includes cooperating camming surfaces having inclined ramps and slots. Selective longitudinal movement of a cam actuator causes vertical movement of a cam plate whereby self-biasing of connector contacts is opposed for ready pin insertion. Engagement between the cam plate and contacts ceases upon reverse movement of the cam actuator to permit the contacts to tightly engage the pins.
