ABSTRACT:
A zero insertion/retraction force connector is disclosed in which a folded spring is mounted in a housing with the folded spring having an arched portion to one side, one end of which serves as a sliding pivot for an extension which curves back towards the arched portion. This extension forms a moveable contact which is deflected towards a conductive stripe on the edge of a printed circuit board when, in one embodiment, a printed circuit board is inserted into the connector such that the bottom of the printed circuit board depresses the arched portion of the spring. Depression of the arched portion causes the sliding pivot to move laterally and rotate such that the extension swings into contact with one side of the printed circuit board and slides upon the conductive stripe in a wiping action while pressing the other side of the board against a vertical wall of the connector to sandwich the printed circuit board between the moveable contact and the wall. The printed circuit board is clamped into place to maintain the contact pressure by the depression of the arched portion. Release of the printed circuit board is accomplished by unclamping the circuit board which permits the upward motion of the printed circuit board and release of the arched portion, with the elasticity of the spring causing the moveable contacts to swing away thereby releasing the printed circuit board.
