Abstract: A fixture for interfacing electrical leads with the terminal edges of a printed circuit card, having a frame for supporting the card, a fixed connector for receiving one of the card's terminal edges and a movable connector slidably mounted on the frame and responsive to the operation of an actuating member for mating with the card's second terminal edge while simultaneously forcing mating of the fixed connector and first terminal edge. As mating occurs, resilient fingers mounted in conjunction with the second connector and previously cammed away from the card engage apertures in the card. These fingers serve to extract the card from the fixed connector when the movable connector is actuated away from the fixed connector toward a stop. At the stop, the fingers are cammed out of the apertures, and the progression of the card is halted while the movable connector continues its motion and thereby decouples from the then stationary second terminal edge.
