  • Patent number: 6603669
    Abstract: A capture device for use with circuit boards of varying thicknesses prevents the spacing between the boards from increasing and has a unitary body including a flexible arm, a clip cavity and multiple living hinges that enable the device to be pivotally self-locked between the circuit boards. The capture device can be engaged and disengaged in poor visibility and limited access areas densely packed with circuit boards. The capture device may be made of a semi-rigid material that provides enough flexibility for the living hinges, yet is rigid enough to exert pressure on the boards and prevent the spacing between the boards from increasing. In alternative embodiments, more than two circuit boards may be secured using alternative configurations of the capture device with either multiple arms or multiple clip cavities.

  • Patent number: 6466449
    Abstract: A disk cage assembly into which multiple disk drives may be removably inserted is formed from two separate frames which are identical in shape and design and include complimentary mating features enabling the frames to be joined to form a symmetrical four-sided structure. The frames are symmetrical about a midpoint and are easily manufactured since all interior surfaces are accessible during the manufacturing process. A surface of the frames defines a plurality of channels into which modular disk drives may be inserted. In one embodiment, the frames are designed to accommodate a mid-panel which is securable within the structure and can be used to increase the number modular disk drives which can be disposed therein. The assembly may be formed from a number of different materials, including structural foam which can be used to help absorb vibrations among the disk drives within the assembly.

  • Patent number: 6239592
    Abstract: A test fixture which holds multiple circuit boards in an edge-to-edge configuration for testing includes a sliding interconnect mechanism which is located between the circuit boards under test. The interconnect mechanism includes an interconnect board on which are mounted pairs of inter-wired frame connectors which mate with the connectors on each of the printed circuit boards to be tested and electrically interconnect the boards. The interconnect mechanism includes guide pins on which the interconnect mechanism slides to accurately align the frame and board connectors and an actuating mechanism to move the interconnect mechanism into position to securely mate the aligned connectors. The actuating mechanism can also be reversed to unmate the connectors and release the boards under test after the tests are completed.
