摘要： A method of maintaining a circuit card in a card rack and a circuit card rack system are disclosed. A card rack including a laterally oriented clamping slot is provided. The clamping slot is at least partially formed from a temperature-contractible material. A circuit card having a clamped side region is provided. At least a portion of the clamped side region is inserted into the clamping slot. A predetermined temperature differential is applied to the clamping slot to reduce a longitudinal dimension of at least a portion of the clamping slot. A compressive force is exerted on the portion of the clamped side region which is located longitudinally within the clamping slot, via thermal expansion of the clamping slot.

摘要： An edge sealing heat-dissipating film includes a heat radiation emitting film, a metal film and a heat radiation receiving film. The heat radiation emitting film has a first opening. The metal film is disposed to the heat radiation emitting film and the metal film has a second opening. The second opening is positioned corresponding to the first opening. The heat radiation receiving film is disposed to the metal film and the heat radiation receiving film has a third opening. Wherein, the shape of the heat radiation emitting film is the same as the shape of the heat radiation receiving film. And the area of the metal film is slightly smaller than the area of the heat radiation receiving film and the heat radiation emitting film. Therefore, the outer periphery of the heat radiation emitting film and the outer periphery of the heat radiation receiving film could be closely bonded together.

摘要： A guide assembly an enclosure-based device such as a computer provided in a rack-mountable chassis. The guide assembly is configured to facilitate blind connector mating such as electrical interconnection between a receiving connector on a previously-mounted board and an edge connector on a circuit board supported in a housing of a module that is slid or inserted into the interior space of the enclosure or chassis. The guide assembly (and devices that include a guide assembly) address the two design challenges discussed above of increasing numbers of circuits in devices that need to be connected and of decreasing pitch between the connectors. The guide assembly is configured, with its mechanical features, to decouple the degrees of freedom (DOFs) between the module being inserted into the chassis and the receiving/mating connector on the previously-mounted board. The guide assembly constrains five out of the six DOFs, which effectively ensures proper connector mating.

摘要： A resistance-limited electrical interface includes a printed wiring board, a bus bar, a U-shaped conductor, and a retainer. The bus bar extends from the printed wiring board. The U-shaped conductor has a first wall and an opposed second wall, the bus bar arranged between the first and second wall to define a conductive joint between the first wall and the bus bar. The retainer is compressively seated between the second wall and bus bar opposite the conductive joint to exert force on the bus bar for retaining the bus bar in the U-shaped conductor and limiting electrical resistance of the conductive joint.

摘要： A circuit card assembly includes a heat sink, a locking mechanism, a first thermal path, and a second thermal path. The heat sink couples to a circuit board and has an upper surface and a lower surface. The heat sink has a channel extending downward along the upper surface of the heat sink. The locking mechanism is disposed within the channel and includes a plurality of solid wedges movably arranged within the channel. Movement of the wedges is effective to secure the circuit card assembly to a holder. The first thermal path extends from the circuit board through the heat sink to the lower surface of the heat sink and removes thermal energy from the circuit board. The second thermal path is formed from the circuit board, through the heat sink, and then through the wedges to the holder. The second thermal path removes thermal energy from the circuit board that is greater than a leakage amount.

摘要： The apparatus is a heat transferring clamp with a heat pipe connecting the clamp's stationary base part to each moveable clamping part. A connecting heat pipe section between the heat pipe sections in the base part and each clamping part is flexible enough to permit both the required clamping and unclamping movements of the clamping part. The heat pipes thereby provide a superior heat transfer path between a clamped circuit board or other device and an available heat sink.

摘要： A circuit board assembly for installation in a cabinet includes a first standards based size first mounting frame portion having a PCB mounted thereto. A second mounting frame portion is connected to the first mounting frame portion having no portion of the PCB connected thereto. A combination size of the first and second mounting frames defines a larger second standards based size. Multiple heat transfer components may be connected to the first or second mounting frame portion provide a conduction/convection cooling path. The first mounting frame portion may include a first false board edge and the second mounting frame portion includes one or more false board edge(s) positioned laterally and oppositely directed to the first false board edge. The first and second false board edges are slidably received in opposed slots created in a cabinet.

摘要： A reverse wedgelock device with multiple draw blocks disposed about a lead screw passing through the draw blocks, wherein the draw blocks may be compressed together and caused to displace about respective wedge surfaces upon tightening of the screw. Compression and displacement of the draw blocks can function to draw anchors associated with the draw blocks inward, which, when engaged with opposing objects, functions to draw the objects together.
