  • Patent number: 7018870
    Abstract: A connect and disconnect assembly for connecting and disconnecting a laser diode having leads to a printed circuit board (PCB). The assembly includes a heatsink having a base plate portion and fins extending from and integral with the base plate portion. The heatsink further includes spacer sleeves extending from a side of the base plate portion opposing the fins. The heatsink connects to the printed circuit board by providing mount screws through the heatsink and spacer sleeves which are received in mount holes formed in the PCB. The laser diode connects to the base plate portion of the heatsink. Laser support blocks connect with the heatsink and support opposing sides of the laser diode. Each laser support block is provided with a dielectric gasket. When the heatsink is mounted onto the PCB, the laser diode leads are forced against corresponding pads provided on the PCB for electrically connecting the laser diode to the PCB.

  • Patent number: 6522546
    Abstract: A universal support frame that holds a printed (PCB) so that both sides are accessible for processing and testing, and which provides an attachment mechanism for holding a mechanism to cool the PCB as it is being processed or tested. The universal support frame includes a base, and a first board support pivotally connected to the base. A pair of support angles are connected at their first ends to the first board support, and are connected at their second ends to a second board support. A variety of PCBs are capable of being held between the first and second board supports since the second board support is adjustable. Furthermore, both sides of a PCB may be accessed since the first board support may be rotated relative to the base. The second board support connects to a bracket for holding a cooling mechanism, such as a fan, that cools the PCB and prevents it from overheating.

  • Patent number: 6481662
    Abstract: A fiber optic cable winding assist tool for securing, routing, and storing fiber optic cables in optical communications systems that quickly and simultaneously lifts the retainer fingers of a mandrel, without breaking them, and releases the retainer fingers once the fiber optic cables are safely within the retainer fingers. The winding assist tool is used with a base having at least one mandrel connected thereto, and may have a spacer disk connected to the mandrel. A spider frame is provided on the spacer disk or mandrel and includes a body portion and arm portions extending from the spider frame body portion. Each arm portion engages a corresponding retainer finger of the mandrel. A thumb screw having a head portion and a threaded portion mates with a threaded opening provided through the spider frame body portion and engages a top surface of the spacer disk.
