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.

Dependent claims

A fixture for interfacing first and second sets of electrical leads with first and second opposite terminal edges, respectively, of a card bearing electrical circuitry, said fixture comprising:

first electrical connector means connected to said first set of leads for mating with said first terminal edge of said card;
second electrical connector means connected to said second set of leads for mating with said second terminal edge of said card;
frame means for receiving and slidably supporting said card between said first and second electrical connector means;
means supporting said second electrical connector means for movement along said frame means;
means on said frame means to guidingly support said supporting means for said second electrical connector means for movement along said frame means;
and
actuatable means secured to said frame means and to said means supporting said second electrical connector means and movable in one direction for displacing said second electrical connector means in a first increment of movement to abut said card and move same along said frame means toward said first electrical connector means to cause a mating of said first electrical connector means and said first terminal edge, said actuatable means displacing said second electrical connector means in a second increment of movement to effect the mating of said second electrical connector means and said second terminal edge.
