A fixture for helping to secure a circuit board to a receiving connector socket is attached to the connector socket. The fixture is then attached to the circuit board with a flowable adhesive. The flowable adhesive could be a hot-melt adhesive. Adhesive layers on the fixture can be used to attach the fixture to side and top surfaces of the connector socket.

A retaining arrangement can secure an electronic module to a body. Two end wedges, each with a ramped end, can be mounted on a rail. At least one inner wedge can be slidably mounted on the rail between the two end wedges, with ramped ends of the at least one inner wedge engaging the ramped ends of the two end wedges. Each of the ramped ends can have a respective angle of between 20 degrees and 30 degrees. An even number of inner wedges can be provided. A pin extending through mounting holes in one of the end wedges, but not extending into the rail, can secure the end wedge to a screw for moving the retaining arrangement into the compressed configuration.

An example bracket unit to control installation of an electronic module is provided herein. The bracket unit includes a bracket body, a bracket plate, and a fastener. The bracket plate includes a receiving member and an alignment indicator. The receiving member to engage with a rail unit and move between an equilibrium position and a displaced position based on a movement of the rail unit. The alignment indicator connected to the receiving member, such that movement of the alignment indicator corresponds to the movement of the receiving member. The fastener to slideably connect the bracket plate and the bracket body together.

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.

A module is retained in a slot of an electronics chassis. A clearance space is provided for receiving the module in a slot of the electronics chassis by controlling an internal pressure of a bellows. The bellows forms a part of a retainer that is disposed on an elongated rail extending along a length of the slot. The bellows defines an internal bellows capsule which contains a fluid. Once the module has been inserted in the slot, the module is secured with the retainer by further controlling the internal pressure of the bellows to exert a force on the module.

An electronic device configured to be mounted in a housing of a cluster, the device comprising a rear body housing at least one mother board configured to be powered by the cluster, a front tray housing at least one electronic board having at least one socket, the front tray comprising at least one fastening member for mounting an expansion card having an edge connector and a fastening portion, the electronic board being connected to the mother board by at least one flexible cable, the front tray being mounted slidable relatively from the rear body between a close position and an open position in which the front tray is at least partially removed from the cluster housing while keeping the rear body into the cluster housing so that an expansion card can be mounted/unmounted from the electronic board without powering off the device.

An electronics enclosure can be a line replaceable unit for installation in a chassis having actively cooled cold plates. The electronics enclosure has a housing, heat spreaders, and moveable heat spreaders. The electronics enclosure can be positioned in the chassis with the moveable heat spreaders close to the housing and thereafter the moveable heat spreaders can be moved away from the housing to press against the cold plates. Heat from electronics within the electronics enclosure can pass from the housing, through the heat spreaders, through the moveable heat spreaders, and into the cold plates.

A circuit card assembly includes a heat sink, a locking mechanism, and a thermal insert. The heat sink couples to a circuit board and has an upper surface and a lower surface. The heat sink has a channel extending downwards along the upper surface thereof. 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 thermal insert is disposed within the heat sink and is an elongated member. The thermal insert is configured to contact a portion of at least one of the solid wedges, thus assisting in removing a first amount of thermal energy from the circuit board.

A device for retaining a printed circuit board module in a mounting groove of a cold plate, the device comprising an elongated housing made of metal, which has a cross-section in the shape of a horizontal U. A pressure piece made of metal is mounted in the housing so as to be displaceable transversely relative to the rotational axis of the housing and comprises a flat clamping surface on the front side. A rotary cylinder can be rotatably mounted in the housing so as to be transversely displaceable relative to the rotational axis. During a rotation, eccentric guide elements can be used to effect a forward displacement of the rotary cylinder. The pressure piece follows the displacement of the rotary cylinder and slides outward. The waste heat of the printed circuit board module is transported via the housing and the pressure piece to the cold plate.

An assembly to connect two electronic components is provided herein. The assembly includes a lever unit with a lever and a base. The lever includes a primary cam member and a secondary cam member connected thereto. The lever also includes a hook member extending therefrom. The base includes a guide structure to engage with a drive pin. Rotation of the lever to move a first electronic component along a y-axis towards, a backplane. The secondary cam member to move the drive pin along the guide structure, and the hook member to engage with a second electronic component and mate the first electronic component and the second electronic component along the second axis.
