A swivel bracket assembly and a method for installing an electrical component to a riser bracket assembly are disclosed. The swivel bracket assembly includes a baseplate; a swivel bracket rotatably attached to the baseplate, the swivel bracket being rotatable between an open position and a closed position; and pads attached to the swivel bracket, at least one of the pads being configured to contact and support the electrical component attached to the riser bracket assembly when the swivel bracket is in the closed position. A method for installing an electrical component to a riser bracket assembly includes receiving the electrical component into a slot of a riser circuit board and pivoting a swivel bracket rotatable coupled to a baseplate from an open position to a closed position to support the electrical component secured to the riser bracket assembly.

A chassis device adapted for an expansion device is provided and includes a case, a base and a latch. The case includes an avoiding portion. The base is disposed on the case. At least one accommodating portion is formed on the base. The latch includes at least one pivoting portion, a first abutting portion and a second abutting portion. The at least one pivoting portion is movably disposed through the at least one accommodating portion. The latch is slidable between a locking position and a non-locking position. The first abutting portion and the second abutting portion respectively abut against the case and the expansion device when the latch is located at the locking position, and the avoiding portion allows the latch to pivot when the latch is located at the non-locking position. Besides, a server including the aforementioned chassis device is provided.

A fastening structure including a base pillar, a pair of elastic arms, and a top pillar is provided. The base pillar is assembled to an object, the elastic arms are connected between the top and the base pillars, and a gap is provided between the elastic arms. The top pillar is adapted to stretch or compress the elastic arms when an external force is exerted to reduce or expand the gap. The top pillar and the elastic arms pass through a through hole of a connector when the elastic arms are stretched to reduce the gap to make the connector contact the base pillar. After the force is removed, the gap between the elastic arms is restored to fasten the fastening structure between the elastic arms and the base pillar in a floating state. An electronic assembly and an operating method of the fastening structure are also provided.

A guide assembly an enclosure-based device such as a computer provided in a rack-mountable chassis. The guide assembly is configured to facilitate blind connector mating such as electrical interconnection between a receiving connector on a previously-mounted board and an edge connector on a circuit board supported in a housing of a module that is slid or inserted into the interior space of the enclosure or chassis. The guide assembly (and devices that include a guide assembly) address the two design challenges discussed above of increasing numbers of circuits in devices that need to be connected and of decreasing pitch between the connectors. The guide assembly is configured, with its mechanical features, to decouple the degrees of freedom (DOFs) between the module being inserted into the chassis and the receiving/mating connector on the previously-mounted board. The guide assembly constrains five out of the six DOFs, which effectively ensures proper connector mating.

An electronic device includes a chassis, a first circuit board, and a second circuit board. The chassis includes a bottom plate. The first circuit board includes a first connector. The second circuit board includes a board body, a second connector, and a locking assembly. The board body is configured to be slid on the bottom plate. The locking assembly includes an operating portion and a locking rod. The operating portion is connected to the board body. The locking rod is configured to be slid between a locked position and a released position along the operating portion. A locking end of the locking rod is toward to the board body. When the second connector and the first connector are connected to each other, and the locking rod is at the locked position, the locking end of the locking rod is in a locating hole of the bottom plate.

An expansion card securing device comprises a frame, a securing member, an elastic member, a pivot and an operating member. The frame has a first engaging portion and a second engaging portion. The securing member has a shaft portion and a securing portion. The securing portion is connected with the shaft portion. The shaft portion has two salient portions protruding from the securing portion. The shaft portion is pivotally connected with the frame via the two salient portions. The securing portion is engaged with the first engaging portion. The elastic member is sleeved at the salient portion closer to the second engaging portion. Two ends of the elastic member abut the securing portion and the frame, respectively. The operating member has a rotating portion and an operating portion. The operating portion is connected with the rotating portion and is engaged with the second engaging portion. The rotating portion is pivotally connected with the salient portion closer to the second engaging portion via the pivot and abuts the side wall having the second engaging portion of the frame.
