Abstract: A drive tray assembly is disclosed for placing drives (e.g., hard disk drives) in a computer chassis in a rotated orientation and without the need for additional tools. The drive tray assembly includes an outer tray on a hinge capable of being rotated away from the computer chassis during drive changes. An inner tray, upon which a drive may be placed, is coupled to the outer tray. When the outer tray is moved to a closed position within the computer chassis, pressing on a handle can cause the inner tray to move from a disengaged position to an engaged position, thus connecting the drive to a drive backplane within the computer chassis.

Abstract: A dust-proof telecommunication system and a method for assembling a dust-proof mechanism are disclosed. The system includes a chassis including an opening on a top side thereof; a PCB located within the chassis; a memory module removably installed on the PCB; and a cover removably coupled to the top side of the chassis. The opening is positioned and shaped such that the memory module is accessible via the opening for easy replacement. The method includes inserting a strip into the opening such that a space is formed between a wall of the opening and the strip; and inserting the memory module into the space formed between the wall of the opening and the strip such that another strip located at a first side of the memory module contacts the wall and the strip contacts a second side of the memory module. The memory module is replaceably coupled to the PCB.

Abstract: A retractable handle assembly for an electronic device includes a base plate having a base plane, a sliding member, and a handle. The sliding member is movable along a first axis that is parallel to the base plane. The handle is movable along a second axis that is perpendicular to the base plane. The sliding member has a ramp surface and a wedge surface. The handle has a mating wedge surface. The ramp surface and the wedge surface are angularly oriented relative to the base plane. The ramp surface is angled to receive a first force, which is perpendicular relative to and directed towards the base plane. In response to the first force, the sliding member moves along the first axis and the wedge surface moves towards the mating wedge surface. The wedge surface moving towards the mating wedge surface causes a second force to deploy.

Abstract: A latch mechanism for securing an expansion card assembly in a computer chassis includes a lever, a stop member, a rotary latch, a first biasing structure, and a second biasing structure. The lever includes a latching end and an opposing pinned end. The stop member extends from the pinned end. The rotary latch is connected to the latching end and includes a receiving chamber and a hook structure. The hook structure includes a notch for receiving a stop pin. The first biasing structure extends from the lever into the receiving chamber and is configured to urge the rotary latch into a locked position. The second biasing structure is configured to urge the lever about the pinned end to an open position.

Abstract: An air-duct module for a server comprises a main body that includes an upper wall and a plurality of side walls extending downwardly away from the upper wall. The main body further includes a plurality of channel walls extending from the upper wall and defining a cable-routing channel located within the main body. The cable-routing channel receives an electronics cable that extends across the main body. The air-duct module has an air passage for guiding air across a heat exchanger within the server. The air-duct passage is defined by the upper wall, the plurality of side walls, and at least some of the plurality of channel walls.

Abstract: An air-duct assembly for a server comprises a main portion and an extension piece. The main portion has a first end region for receiving air from a fan and a second end region with a first attachment feature. The extension piece has a second attachment feature for mating with the first attachment feature. The extension piece guides the air from the second end region of the main portion to a terminal end of the extension piece. The air-duct assembly can be used with a first heat exchanger in a first configuration in which the extension piece is mated to the main portion, and the first heat exchanger is located within the extension piece. The air-duct assembly can also be used with a second heat exchanger in a second configuration in which only the main portion is used by itself and the second heat exchanger is located within the main portion.

Abstract: A computer chassis can include a top cover that can be secured and removed without the need for tools. Sidewalls of a chassis base can include receiving slots that receive bosses of the top cover. A latch receiver mounted to a bottom surface of the chassis base can receive a sliding body of a latch assembly of the top cover. The computer chassis can be assembled by placing the top cover on the chassis base such that the bosses are placed into the receiving slots, and such that the sliding body fits within the latch receiver. In this position, rotation of a lever of the latch assembly can force the top cover to move with respect to the chassis base, pushing the bosses of the top cover towards distal ends of the receiving slots of the chassis base, thus securing the top cover to the chassis base.
