  • Patent number: 10170391
    Abstract: A backside initiated uniform heat sink loading system includes a system board assembly, a heat sink assembly, a loading plate, and a fastener. The system board assembly includes at least one processing unit. The heat sink assembly is mounted upon the processing unit from a topside of the system board assembly and includes a plurality of tension members that extend through the system board assembly. The loading plate is mounted to the plurality of tension members from a backside of the system board assembly. The fastener engages with the loading plate from the backside and forces the loading plate away from the system board assembly. As a result, the tension members uniformly force the heat sink assembly upon the processing unit to seat the processing unit with the system board assembly and to thermally contact the heat sink assembly with the processing unit.

  • Patent number: 9351428
    Abstract: An apparatus includes a rigid structure having first and second collars, a quick connect connector having first and second shoulders, and a spring biasing the connector toward an extended position with the first shoulder against the first collar and the second shoulder against the second collar. The first collar and the first shoulder form an inwardly and rearwardly angled contact surface there between, and the second collar and the second shoulder form an inwardly and rearwardly angled contact surface there between. The connector is centered in the first and second collars unless acted upon by a force overcoming the spring and pushing the connector to a retracted position with the first and second shoulders out of contact with the first and second collars. When retracted, the connector may adjust its position longitudinally, vertically, laterally or angularly to facilitate coupling with a mating fixed quick connect connector.

  • Patent number: 9319148
    Abstract: A system comprises an interposer positioned between an integrated circuit and a system planar. An electrical/optical transceiver is coupled to the interposer, wherein the electrical/optical transceiver converts electrical signals into optical signals. The interposer comprises a first set of electrical conductors that is electrically coupled to non-Input/Output (I/O) electrical connectors on the integrated circuit, and wherein the first set of electrical conductors passes through the interposer to directly connect the non-I/O electrical connectors on the integrated circuit to the system planar. The interposer further comprises a second set of electrical conductors that is electrically coupled to input/output (I/O) electrical connectors on the integrated circuit, wherein the second set of electrical conductors traverses through the interposer to the electrical/optical transceiver to convert electrical I/O signals from the integrated circuit into optical I/O signals.

  • Patent number: 9173310
    Abstract: A latch comprises a frame securable to a device enclosure, and a handle slidably secured to the frame, wherein the handle can slide between an inward position and an outward position, and wherein the distal end of the handle has a drive pin. The latch further comprises a rigid pawl having a latch key, a distal end pivotally secured to the frame, and a slot that receives the drive pin. Inserting the handle causes the drive pin to move within the slot, push the pawl toward a side of a chassis bay, and deploy the latch key into engagement with a slot in the side of the chassis bay. Withdrawing the handle causes the drive pin to move within the slot, pull the pawl away from a side of the chassis bay, and withdraw the latch key out of engagement with the slot in the side of the chassis bay.

  • Patent number: 9022434
    Abstract: A latch selectively secures a compute node enclosure into a chassis bay. The latch comprises a frame securable to a proximal end of the compute node enclosure. A handle is pivotally secured to the frame intermediate a proximal end of the handle and a distal end of the handle so that the handle can be pivoted between a closed position and an open position. A proximal end of a pawl is pivotally coupled at to the distal end of the handle, wherein the pawl includes a landing at a distal end of the pawl and a latch key intermediate proximal and distal ends of the pawl. Movement of the handle positions the pawl into engagement with a slot in chassis bay to assist installation and removal of the compute node enclosure.

  • Patent number: 8979561
    Abstract: First and second memory module connectors are secured in end-to-end alignment on a circuit board for receiving memory modules along a central plane. Each memory module connector has an ejector latch pivotally coupled to the adjacent ends of the memory module connectors to pivot about an axis perpendicular to the plane. A distal portion of an upper arm of each ejector latch lies on opposite sides of the plane, such that the ejector latches interleave when either ejector latch is pivoted to an open position. The adjacent ends of the first and second memory module connectors are separated by a narrow gap, such that pivoting of the either ejector latch from a closed position to an open position will push the other ejector latch toward a closed position.

  • Patent number: 8944832
    Abstract: A method includes securing a midplane in a chassis, wherein the midplane has one or more connectors, and securing a circuit board in a module, wherein the circuit board has one or more connectors secured along a leading edge of the circuit board for selectively connecting with the one or more connector on the midplane. The method further includes positioning the module so that the circuit board within the module is orthogonal to the midplane, and manually actuating a handle from an unlatched position to a latched position to rotate a cam plate and cause a cam surface of the cam plate to pull the circuit board toward the midplane and connect the one or more connector on the circuit board with the one or more connector on the midplane.

  • Patent number: 8936477
    Abstract: An apparatus includes a chassis securing a midplane and forming a bay orthogonally aligned with the midplane. A module secures a circuit board with connectors for connection with connectors on the midplane. A handle includes a proximal link pivotally coupled to the module, a distal link pivotally coupled to the proximal link, and a spring for transmitting torque from the distal link to the proximal link. A cam plate is secured for rotation with the proximal link, wherein the cam plate includes a cam surface for engaging a latch arm that extends into the bay. Still further, an over-center spring is used to retain the cam plate in a latched position. Manual actuation of the handle from the unlatched position to the latched position causes the cam surface to pull the circuit board toward the midplane and connect the circuit board connectors with the midplane connectors.
