International Classification:

G06F 116

US Classification:

361685, 361683, 361686, 312236

Abstract:

A computing system includes a frame and a drive mounting structure for mounting one or more drive units within the computing system, with the drive mounting structure being pivotally and removably mounted on the frame to move between an operating position, in which an internal end of a drive unit mounted within the drive mounting structure is held within the computing system, and a service position, in which the internal end of the drive unit extends outward from the computing system. In the service position, access is provided to an open end of the drive mounting structure, into which the drive unit can be installed, to the internal end of the drive unit, for attachment of a cable, and to a side of the drive mounting structure, through which fasteners are driven to mount the drive unit within the drive mounting structure.

International Classification:

F16B019/00

US Classification:

411508, 411509, 411510

Abstract:

A hand tightened locking pin using a unique internal cam configuration to lock the pin assembly. The pin assembly includes a sleeve and a locking cam unit. The sleeve includes anti-rotation protrusions that match a keyhole in a first metal plate to prevent rotation of the sleeve. The pin assembly is inserted through the keyhole of the first metal plate and a circular hole in a second metal plate that lies on the first metal plate. When the locking cam unit, which is inside the sleeve, is rotated, a lower portion of the sleeve expands, locking the first and metal plates together. The cam is locked in position by concave shaped ends that mate over bulges in the lower portion of the sleeve. A locked/unlocked indicator on top of the pin assembly indicates when the concave shaped ends are mated with the bulges.

International Classification:

H01R 13/648

US Classification:

439 92, 361758

Abstract:

A system permitting vertical and horizontal movement of a first board for proper mating of a first connector on the first board to a second connector on a second board. The first board being aligned pivots about a pivot pin, which is mounted on a mechanical plate at a first end of the board that is opposite to a second end of the board to which a first connector is mounted. This pivoting allows transverse (horizontal) movement of the first board. The first board floats on springs located between the first board and the mechanical plate to which the first board is mounted. These springs afford longitudinal (vertical) movement of the first board, while also providing a friction fit between the first board and the mechanical plate. When the first connector is aligned properly with as second connector on a second board, the first and second connectors can be mated.

International Classification:

H01R 13/62

US Classification:

439157, 439372

Abstract:

A printed circuit board is configured as a daughterboard to include at least one lever pivotable between open and closed positions. The lever applies leverage to a card guide structure to selectively urge the daughterboard into or out of engagement with a connector of a motherboard. A manually operable pivotable latch member is mounted on the daughterboard for selectively retaining the lever(s) in a closed position. The latch member may be spring biased so that it maintains the lever(s) in the closed position and returns to a latch position after being manually pivoted to release the lever(s). The lever(s) may be spring biased toward the open position. An optical switch may be provided on the daughterboard to sense whether the lever is in a closed position, and to responsively interrupt power and/or bus signals to the daughterboard when the lever is not sensed in the closed position.

H05K 7/20

US Classification:

361719, 361704, 257719, 24458, 24513

Abstract:

A heat sink retention assembly for retaining a heat sink in thermal contact with a CPU while transmitting load away from the CPU. The heat sink retention assembly includes a frame sized to receive the heat sink, the frame including opposing pin capture channels and a wire module. The wire module includes an upper handle section and a lower pivoting section. The wire module is pivotably coupled to the frame at the lower pivoting section. The wire module further includes opposing end pins, wherein each pin is moveably retained within and extends through a corresponding pin capture channel such that when the wire module is rotated with respect to the frame, the pins travel within their respective channels in order to engage the heat sink.

International Classification:

H05K 7/18

US Classification:

361801, 361754, 361759

Abstract:

An apparatus, system, and method are disclosed for connecting and disconnecting daughter cards. A handle urges a locking member toward a base comprising a stop and a channel. The channel may direct the locking member to a specified position. The locking member biases the catch and the biased catch engages with the stop. The stop and the channel of the base secure the locking member to the base. In addition, the handle urges the locking member away from the base. The handle also urges an actuator to unbias the catch. The handle further disconnects the locking member from the base as the unbiased catch does not engage the stop.

Abstract:

A latch mechanism for securing a module in an electronic component chassis includes at least one lever arm attached to the module and rotable between a latched and unlatched position, at least a portion of the lever arm having an interference fit with the chassis when the lever arm is in the latched position.
