Abstract

A pair of cams judiciously positioned at each end of a side-entry edge-card connector is actuated by the card, which in turn actuates the spring contacts of the connector. The diagrammatic illustrations in Figs 1 and 2 show the principles of the construction and operation of the improved arrangement. A pair of cams 1 and 3 is provided, the cams being located at the opposite end of a ZIF (zero insertion force) connector, the details of which are not shown for the sake of clarity. The cams pivot about points 2 and 4 and have the configurations shown. Element 5 is a driving piece or cam which is coupled to the ZIF springs to operate the springs between their contacting and non- contacting positions. Fig. 1 shows the operation taking place during the insertion of a card 7 in the direction from left to right.

Cam-Actuated Zero Insertion Force Connector

A pair of cams judiciously positioned at each end of a side-entry edge-card connector is actuated by the card, which in turn actuates the spring contacts of the connector. The diagrammatic illustrations in Figs 1 and 2 show the principles of the construction and operation of the improved arrangement. A pair of cams 1 and 3 is provided, the cams being located at the opposite end of a ZIF (zero insertion force) connector, the details of which are not shown for the sake of clarity. The cams pivot about points 2 and 4 and have the configurations shown. Element 5 is a driving piece or cam which is coupled to the ZIF springs to operate the springs between their contacting and non- contacting positions. Fig. 1 shows the operation taking place during the insertion of a card 7 in the direction from left to right. At this time the card moves over the flat portion of cam 1, and drive member 5. When the right side of the card comes in contact with cam 3, it causes cam 3 to rotate clockwise, with the result that driving piece 5 moves to the left, as will be apparent from the drawing. In turn, cam 1 is forced to rotate in a clockwise direction, so that the card 7 is locked in place. Concurrently, the motion of driving piece 5 to the left closes the ZIF springs, establishing contact between them and the card contact tabs. Fig. 2 shows the operation taking place when a card is extracted. The card 7 is pulled to the left, and the left e...
