In a circuit board unit storing circuit boards in a plurality of columns and rows, mounting and demounting of the circuit boards are locked without increasing an external shape of a product compared to a conventional configuration. Substrates are provided that have cut-away portions and a lock structure of a circuit board unit includes a slide portion that is formed of a frame member having openings arranged in a grid shape into which the circuit boards are able to be inserted and that is slidably mounted on a circuit board insertion surface of a front mask, and projection portions that are provided in the slide portion and are fitted into the cut-away portions of the circuit boards stored in a case when the slide portion is slid in one direction.

There is described a control peripheral post of railway field devices, comprising: at least one row of control modules operatively connected or connectable by electric cables to field devices; a support frame having a front side and housing said row of control modules; wherein said support frame comprises at least one anti-extraction bar positioned on the front side of the support frame, said bar being adapted to selectively take an extraction configuration, wherein said bar is positioned in such a way as to permit the extraction of the control modules from the front side of the support frame, and a blocking configuration, wherein said bar is positioned in front of said row of control modules so as to prevent the extraction of the control modules (4, 5) of said row from the front side of the support frame.

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.

Provided is an apparatus for inspecting a magazine including a plurality of partially-finished products. The apparatus is configured to inspect a stopper of the magazine before providing the magazine to a packaging process, and further configured to classify the stopper into a normal product. The magazine comprising the stopper classified as the normal product is into the packaging process.

A fixing member is used for fixing a plate to a frame. The fixing member includes a body and a fixing plate extending from the body. The body can lock with the frame along a first direction substantially parallel to the body. The fixing plate is configured to deform along a second direction substantially perpendicular to the first direction and lock with an aligning portion of the plate. An electronic device is also provided.

Sockets that provide easy access for users to change cards while allowing the use of thinner device enclosures. One example provides a socket having two positions. When the socket is in an open state, the card may be oriented in a direction substantially away from the main logic board. When the socket is in a closed state, the card moves such that it is oriented at least closer to being in parallel to the main logic board.

The present disclosure provides for a computing system. The computing device may include a motherboard. The motherboard may include a first edge, a second edge, a third edge opposite the first edge, and a fourth edge opposite the second edge. The first edge may be longer than the second edge. The computing device may further include socket for a central processing unit disposed on the motherboard. The computing device may further include an expansion connector. The expansion connector may include one or more expansion slots oriented parallel relative to the motherboard, and be configured to receive an add-on card such that the add-on card is parallel relative to the motherboard.

A rack security system includes a locking mechanism connected to a server. The locking mechanism is configured to lock onto the busbar of a rack. When the locking mechanism is locked to the busbar, the locking mechanism may prevent removal of the server from the rack. When the locking mechanism is unlocked, the server may be removable from the rack.

The present disclosure concerns a slotfiller (1) for closing a slot (21) in a computer-rack-insertable component (20), wherein the slotfiller (1) comprises at least two finger-grippable cup elements (2), and a hinge (3) connecting the cup elements (2). Therein, the slotfiller (1) is configured to be insertable into the slot (21) by pressing of the cup elements (2) towards each other and is configured to at least partially cover an open surface area of the slot (21) by releasing of the cup elements (2) in the inserted state. The present disclosure also concerns a computer-rack-insertable component (20) and a computer rack (100), each comprising at least one slotfiller (1).

A server system is disclosed. The server system includes a riser bracket having a slot and an internal space, the internal space being an operation space for allowing a physical user action; a Peripheral Component Interconnect Express (PCIE) card inserted in the slot of the riser bracket, the PCIE card having a power connector, the power connector being configured to receive a power cable, the internal space being adjacent to the power connector; and a hinge mechanically coupled to the riser bracket near the power connector, the hinge being pivotable between a first position and a second position, the hinge covering the internal space in the first position, the hinge uncovering the internal space in the second position.
