A subrack including a frame defining a subrack space and adapted to receive a device module to an operative position, the frame comprising four side walls and an end wall. The subrack comprises a coupling system adapted for coupling the subrack to four other subracks in order to form a subrack matrix, the coupling system comprising at least one wall recess on an inner surface of each of the side walls, and at least one primary screw hole in each of the side walls such that the at least one primary screw hole is located in the at least one wall recess.

An apparatus and method comprising a rack and a translation mechanism. The rack may be configured to hold components. The rack may comprise movable rack segments that are movable independently of each other. The translation mechanism may be configured to move a portion of the movable rack segments relative to another portion of the movable rack segments inside a platform such that internal access to at least a portion of the components is provided inside the platform.

A quick releasing device, which is adapted to be fixed in or removed from a slot of a casing, is provided. The quick releasing device includes a frame, an arm and a handle. The frame has a hole. The arm is disposed at one side of the frame and a part of the arm corresponds to the hole. The handle is rotatably disposed at another side of the frame to rotate between a working position and a retracting position. The handle includes a pressing member whose position corresponds to the hole. The pressing member of the handle passes through the hole of the frame and pushes the arm when the quick releasing device is inserted into the slot of the casing and the handle is rotated from the working position to the retracting position, deforming the arm and interfering with a wall surface of the casing beside the slot.

A server structure includes an outer frame, a drawer box, a wire harness, and at least one wire harness bracket. The outer frame has a bottom plate and a fixed wall and forms an opening opposite to the fixed wall. The drawer box is passed into the outer frame through the opening. The wire harness has folded portions and is folded at each folded portion and disposed between the fixed wall and drawer box. The wire harness contains a signal cable and a power cable. The wire harness bracket ties the wire harness and has a sliding mat pressing at the bottom plate. When being removed from the opening, the drawer box moves away from the fixed wall and drives the wire harness to spread out each folded portion. The sliding mat supports the wire harness to separate the wire harness and bottom plate to facilitate movements and stretches.

An electronic module, such as a power module, may include a latch having two or more protrusions where a first protrusion can fix the electronic module into a shelf and the second protrusion can be a curved protrusion that activates the latch when an adjacent electronic module is inserted into or removed from the shelf In some embodiments, a third protrusion may be included, where the first protrusion and the third protrusion both fix the electronic module to the shelf and are activated by the latch. Also, a shelf may include a partition between two electronic module receptacles that has a width that is less than a protrusion extending from a side wall of one of the electronic modules.

A module ejection mechanism is adapted to be disposed on a rack and carries an expansion module. The module ejection mechanism includes a tray, a linkage member, and an operating member. When one end of the operating member outside the rack is pulled, the other end of the operating member drives the linkage member to pivot. When the linkage member pivots, the linkage member makes the tray move in an ejection direction. When the tray moves in the ejection direction, an abutting element of the tray is adapted to eject the expansion module from the rack.

The disclosure relates to handle mechanism and casing assembly. The handle mechanism is adapted to be installed on a slidable plate body. The handle mechanism includes handle component, latch component, and releasing component. The handle component has engaged position. The handle component includes first hook portion and first pushing portion. The first hook portion has first contact surface. The latch component is slidably disposed and has second hook portion and first contact portion. The second hook portion has second contact surface configured to contact the first contact surface. The releasing component is pivotably disposed and has pressed portion and second pushing portion. When the handle component is pivoted from the engaged position, the first pushing portion pushes the pressed portion so as to force the second pushing portion to push the first contact portion so that the second contact surface is forced to leave the first contact surface.

An electronic device includes a housing, a first electronic component, a second electronic component, two resilient assemblies, and two rotating levers. The housing defines an accommodating space. The second electronic component is fixed in the accommodating space. Each rotating lever includes a first end and a second end. A distance between the second end and a rotation shaft is less than a distance between the first end and the rotation shaft. A handle is rotationally fixed on the first electronic component. When the first electronic component slides into the accommodating space, the handle is rotated toward the first electronic component, the handle drives the two rotating levers to rotate and resist against the resilient assemblies, and the handle overcomes an elastic force applied by the resilient assemblies onto the rotating levers, so that the first electronic component connects with the second electronic component without gaps.

A latch assembly includes a lever arm affixed to a latch pivot point of rotation with a cam having a connecting slot. A load mechanism is configured to apply a force on the latch pivot point to retain the lever arm in a first position. The load mechanism is tuned to apply the force along a tolerance range of operation of the latch assembly.

Example latching assemblies and electronic devices including the latching assemblies are disclosed. In an example, an electronic device includes a housing including a cavity to receive a peripheral device therein. In addition, the electronic device includes a latching assembly disposed within the housing. The latching assembly includes a latch biased toward the cavity to engage with the peripheral device, and a block. Displacement of the block is to slidingly engage the block along the latch and thereby withdraw the latch from the cavity.
