A computing system includes a chassis and a cage. The chassis includes one or more locking hooks. The cage includes a handlebar, a bar-linkage assembly, and a crank coupled to both the handlebar and the bar-linkage assembly. Rotating the handlebar from an unlocked position to a locked position lowers the cage relative to the chassis until the cage is locked in the one or more locking hooks of the chassis.

Housing structure for PCI Express expansion electronic boards able to mechanically stabilize said PCI Express expansion electronic boards so as to guarantee the correct functioning, performance and integrity of the electric interconnection between them and the basic electronic board to which they are connected if there are mechanical stresses such as knocks or vibrations, in order to be able to use PCI Express expansion electronic boards in the automotive field, or in scenarios characterized by perturbations of the important mechanical type. The present invention also concerns an assembly method of the housing structure.

The present disclosure relates to an IED configured for use as a protection relay in an electric power system. The IED comprises a plurality of cassettes connected to a backplane, with at least two cassettes mounted adjacent each other. Each of the cassettes comprises a housing profile in the form of a rectangular tube having an envelope wall of a heat conducting material, and at least one electronic card arranged in a card slot within the tube formed by the housing profile, which at least one card is electrically connected to the backplane. Adjacent cassettes are separated a distance such that air canals are formed between their respective housing profiles.

A server device includes a chassis, some power cages, a spring leaf structure and a power supplying unit. The power cages are arranged inside the chassis. Two of the power cages define a space therebetween. The power cage includes a first plate having a first and a second holes. The spring leaf structure includes a main body, a blocking plate and an unlocking plate. The main body connects to the first plate. The blocking plate and the unlocking plate protrude to the space respectively through the first and the second holes. The blocking plate includes a straight edge. The unlocking plate includes a curved edge. The power supplying unit includes a main and a subsidiary plates. The subsidiary plate and the main plate form a stair structure. The subsidiary plate is configured to abut against the straight edge or the curved edge.

A connector gap between a module connector mating surface and the backplane connector of a chassis may be eliminated through a mechanism that forcefully pushes (or pulls) the module towards the backplane and/or forcefully pushes (or pulls) the backplane toward the module. A spring-loaded or resilient element may be used to fasten the module in a way that effectively fills any designed-in and tolerance-induced gap in the connector interface, allowing the connector to fully seat. In addition, a gasket or other compressible member may be included at the connector mating interface. The gap in the connector interface may be reduced by introducing adjustable card cage members that are capable of being set during the assembly or manufacturing process using special alignment fixtures. The gap in the connector interface may also be reduced by introducing a higher tolerance capable manufacturing process, such as machining, to the card cage sub-assembly.

A computing card support system, including: a cage positioned on a PCB, including: a first support structure; a second support structure; a cover that is removably coupled to the support structures and positioned opposite to the PCB, the cover including a grounding material positioned along an inner surface of the cover, the inner surface of the cover facing the PCB; computing cards that are i) coupled to the PCB at a first end of each respective computing card and ii) positioned within the cage, each of the computing cards including conductive pads positioned at a second end opposite to the first end of the respective computing card, wherein the computing cards extend from the PCB toward the cover such that the grounding material of the cover is in contact with the conductive pads of each of the computing cards to provide electrical grounding of the computing cards.

A carrier assembly configured to facilitate manufacture of a printed circuit board assembly includes a bottom frame defining a generally rectangular configuration and having a length and a width. The bottom frame is adjustable to vary at least one of the length or the width thereof. The assembly further includes a core releasably positionable on the bottom frame and configured to support a circuit board thereon. A carrier assembly system includes the bottom frame and a plurality of cores.

A blank panel (1A) of the present disclosure includes a partial panel (10) and a partial panel (20), in which the partial panel (10) includes an attachment portion (11) attached to a rack (2) and a link portion (12) linked to the partial panel (20), and the partial panel (20) includes an attachment portion (21) attached to the rack (2) and a link portion (22) linked to the partial panel (10).

Systems and methods for improved circuit board removal and/or reinstallation are provided. A circuit board removal system can include a frame including a channel arranged in a plate of the frame. A disengagement slider can include a mounting surface and a first portion including a first cam surface, where the disengagement slider is arranged within the frame. A separator can include a second cam surface and can be arranged in the channel of the plate. The first cam surface and the second cam surface can be nested with each other when the disengagement slider is in an inserted position. The disengagement slider can be configured to slide the separator in the longitudinal direction when the disengagement slider is removed from the frame due to the interaction of the first cam surface with the second cam surface.

The disclosure relates to a cage and an electrical device having the same, where the cage is configured to accommodate at least one expansion card and includes a cage body, a rail, and at least one holder. The cage body is configured to accommodate the at least one expansion card. The rail is fixed on the cage body. The rail has a groove configured for an insertion of the at least one expansion card. The at least one holder is movably disposed on the cage body. Part of the at least one holder is removably located in the groove. The at least one holder is configured to block the at least one expansion card in the groove.
