  • Patent number: 4996631
    Abstract: A circuit board ejector/injector system enabling the insertion and removal of circuit boards from a card cage is provided. A lever handle is rotatably mounted on an exterior corner of the circuit board in a manner that permits the lever handle to extend out and through an opening formed in an outer front panel of the card cage. Insertion and removal of the circuit boards is accomplished by the selective rotation of the lever handle, with only one of a pair of finger extensions located on the lever arm cooperatively inter-engaging with the circuit board, depending upon the direction of lever handle rotation. Reversal of the rotational direction causes the other finger extension to inter-engage with the circuit board, and the removal/insertion process to be reversed.
