Abstract
An injector/ejector mechanism for a printed circuit card of the type that has front, rear and opposite side edges, a face plate at the front edge and a connector at the rear edge of the card in which slides on chassis card guides adjacent to the side edges of the cards to a home position in a chassis which connects that connector to a mating connector on a motherboard in the chassis. The mechanism includes a dog having spaced-apart first and second lobes, and a pivot pivotally connecting the dog to the card adjacent to the front edge thereof whereby the dog can pivot parallel to the card. The dog is pivotable between a first position wherein the first dog lobe overhangs the card side edge and engages a first surface of the card guide when the card is not in its home position and a second position wherein the second lobe overhangs the card side edge and engages a second surface of the card guide behind the first surface when the card is in its home position. A lever arm and drag link are provided for pivoting the dog between its first and second positions. The mechanism requires minimal space on the printed circuit card and a minimal opening in the face plate of the card.
