  • DUAL-CAM EJECTOR ASSEMBLY
    Publication number: 20130130528
    Abstract: A dual-cam ejector assembly for a card, such as a line card, is provided. The ejector assembly comprises an elongated ejector arm having its distal end coupled to the line card so as to provide a first axis of rotation for the ejector arm. The ejector assembly further comprises an ejector cam coupled to the line card so as to provide a second axis of rotation for the ejector cam. The ejector assembly also comprises a cam pin extending from the ejector cam that couples the ejector cam to the ejector arm such that pivoting of the ejector arm around the first axis of rotation causes the ejector cam to pivot around the second axis of rotation.
