  • Patent number: 5383793
    Abstract: An adjustable height and position retainer for releasable retaining a printed circuit card in a circuit card edge connector. The retainer includes an elongated base member for attachment to the side of a circuit card edge connector, an elongated retaining post, and a clamp assembly slideably attached to the retaining post and positionable at any selected position along the length of the retaining post. The retaining post is slideably attached to the base member such that the post is secured in an orthogonal relationship with the circuit card edge connector and parallel with a circuit card installed into the edge connector, yet the retaining post is positionable at any selected position along the length of the base member. The clamp assembly includes an extrusion which holds the top edge of a printed circuit card installed into the circuit card edge connector.
