Ejection Mechanism for Circuit Boards

Abstract

Damage to connectors reduced and special tools not needed. Clockwise rotation of screw tightens wedges against mounting body and right heat sink. Counterclockwise rotation of screw drives bottom wedge downward and jacking ring upward, pulling pins away from mating connector. Screw in mechanism turned to produce jacking force that disengages board from mating connector. Force parallel to connector pins do not bend or brake. When disengaged, board protrudes from assembly and readily grasped by operator.
