The pressing part is connected with the sliding part through the elastic part. The pressing part includes a second positioning structure. The second positioning structure is detachably engaged with one of the plural first positioning structures.

A secure electronic device with matching disassembling tool includes a housing and an electronic element. The disassembling tool includes a securing member, a first elastic disassembling member, and a second disassembling member. The securing member is mounted to the housing. The securing member includes an elastic locking block locked to the electronic element. The first elastic disassembling member can reach and be inserted into the securing member. The second disassembling member is inserted in the first disassembling member. When the second disassembling member is then rotated, the first disassembling member is deformed to press the elastic locking block, which unlocks from the electronic element.

A remote releasing module includes a bracket, a toggle button, and a moving member. The bracket includes a first end portion and a second end portion away from each other. The toggle button is pivotally connected to the first end portion of the bracket and includes a first driving portion. The moving member is movably disposed on the bracket and extends from a position close to the first end portion to the second end portion. The moving member includes a second driving portion disposed on the first driving portion so as to drive the toggle button to move. A circuit board device including a circuit board body, a connector slot, and the remote releasing module is also provided. The connector slot is disposed on the circuit board body.

A mounting assembly for accurately positioning, attaching, and supporting a circuit board such as a midplane board within a chassis. The assembly's design facilitates an improved assembly method that includes fastening the board to the chassis so to provide reliable connector mate and rapid assembly. The mounting assembly includes a clamp member) and a spring assembly that act in combination to secure a circuit board onto datum features provided on a chassis and/or its modified and/or lightweight alignment bulkhead, which is part of the new assembly. The new assembly design enables a tight tolerance loop between mating components while also providing a more consistent connector engagement when compared with many prior device designs. In some embodiments, a single fastener (e.g., a nut) is used to attach the clamped and captured circuit board to the chassis. The board is “captured” as it is sandwiched between the modified bulkhead and the clamp.

A body part of a KVM (Keyboard, Video, Mouse) switch includes a clamp that holds a cable and is movable in a horizontal direction, and a stay that is equipped with the cable clamp and is movable in a depth direction of the body part to eliminate of the cable hanging down.

An expansion card holder assembly that accepts different size expansion cards is disclosed. The expansion card holder assembly includes a metal base with grooves that roller features of a metal slide bracket fit into. The metal slide bracket is positioned along the metal base for different size expansion cards. The metal slide bracket is connected with a metal cover that is opened to accept expansions cards. A connector is provided for the expansion card to connect with printed circuit board.

A locking mechanism for securing different expansion cards in a slot of a chassis of a computing device is disclosed. The locking mechanism includes a base and a main body. The base is coupled to the chassis and movable between an open position and a closed position. The main body is coupled to the base and movable between a first orientation and a second orientation. When the base is in the closed position and the main body is in the first orientation, a first mating feature of the main body engages an expansion card having a first form factor inserted into the slot. When the base is in the closed position and the main body is in the second orientation, the second mating feature engages an expansion card having a second form factor inserted into the slot of the chassis.

An M.2 fastening system has an M.2 riser card with two module-receiving sides and a plurality of adjustment positions. The M.2 fastening system further has a pair of M.2 fasteners mounted respectively on the module-receiving sides. Each M.2 fastener has a main body defined by a top surface and a bottom surface; a module attachment extending from the top surface; and a hook extending from the bottom surface along a lateral side of the main body. The hook of one of the M.2 fasteners is received through an attachment aperture of an adjustment position. The hook is pressed-fit over the top surface of the main body of another M.2 fastener. The hook secures the M.2 riser card between the pair of M.2 fasteners in a tool-less manner.

A structural subassembly for use in an information handling system chassis may include a first portion, a second portion, a common wall, and one or more mechanical features. The first portion may be configured to receive one or more of a first type of information handling resource. The second portion may be configured to receive one or more of a second type of information handling resource. The common wall may divide the first portion from the second portion. The one or more mechanical features may be configured to engage with one or more respective mechanical features of the information handling system chassis in order to perform at least one of guiding of the subassembly relative to the information handling system chassis during insertion or removal of the subassembly into or from the information handling system chassis and retention of the subassembly relative to the information handling system chassis.

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.
