  • 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.

  • Patent number: 5303996
    Abstract: A cable or wire (information bus, power supply, etc.) retention method and apparatus for modular computer cabinets and the like in which the cabinet frame end walls have notch-like voids. The preferred embodiment for a cable retainer has a frame member with two cantilever portions, which frame member is spot-welded to several struts at other (non-cantilever) portions. The top and bottom struts protrude the frame member, and are longer than the distance between the cabinet end walls. The cable retainer is connected to the cabinet by inserting one pivoting strut tip into a receiving hole and causing the cantilever portion nearest the receiving hole to deform (causing deeper penetration of the inserted tip) so that a clearance is obtained between the other pivot end and its corresponding receiving hole, prior to releasing the cable retainer. Insertion is completed by pivoting the cable retainer to an upright position to latch the latching ends in cabinet end wall grooves.
