An electronic device is provided. The electronic device includes a device housing, a circuit board, and a board module. The device housing includes a restriction unit. The circuit board includes a circuit board connector, wherein the circuit board is disposed in the device housing. The board module includes a module housing, a module board, a module connector, and a preload unit. The module connector is disposed on the module board. The preload unit and the module board are disposed on the module housing. The preload unit is connected to the restriction unit and applies a first elastic force toward the restriction unit. The module connector can thus be sufficiently connected to the circuit board connector.

A handle assembly may include a base, a handle rotably coupled to the base via a hinge, the handle comprising a lock integral to the handle and mechanically coupled to a remainder of the handle via a spring having a spring force that biases the lock in a locked position relative to the handle. The base may include a mechanical retention feature for receiving and mechanically retaining an information handling resource. The base may also include one or more features configured to, as the handle is translated into a closed position relative to the base, mechanically engage with the lock to overcome the spring force that biases the lock in a locked position and allows the lock to return to the locked position in order to maintain the handle in the closed position.

An electronic device includes: a substrate at which an electronic component is mounted; and a resin case configured to accommodate the substrate internally, in which: the case has an attachment portion configured to attach the case to a flat plate-shaped fixing portion of a fixture target by the fixing portion being inserted into the attachment portion and the attachment portion engaging with the fixing portion; the attachment portion has a first pressing portion having a convex portion that is inserted into a concave portion of the inserted fixing portion, and a pair of second pressing portions that hold between them respective side faces of the inserted fixing portion; and leading end sides of the pair of second pressing portions abut on the inserted fixing portion and are resiliently deformed in directions away from each other, holding between them the respective side faces of the fixing portion in a state in which the leading end sides have been resiliently deformed.

An ejector device comprising a housing block; an ejector handle adapted to alternate between an open position and a closed position, having first and second rack engagement features, a sloped feature, and a notch; a trigger latch adapted to alternate between a latched position and an unlatched position, and having a sloped feature adapted to engage the sloped handle feature, and a hook adapted to engage the ejector handle notch; and an ejector button adapted to alternate between a pressed position and an unpressed position; wherein the housing block comprises a space for receiving the ejector handle and the latching trigger; the ejector handle is pivotally attached to the housing block and is adapted to urge the latching trigger to the unlatched position when the ejector handle moves to the closed position and the sloped handle feature engages with the sloped latching trigger feature; and the latching trigger is pivotally attached to the housing block, and is adapted to be urged to the unlatched position as the ejector button moves to the pressed position and impinges on the latching trigger.

One aspect of the instant application provides an apparatus for locking a circuit board in position. The apparatus can include a cam latch, a plunger, and a hinge pin coupling the cam latch and the plunger. The cam latch is positioned to rotate around the hinge pin, and the rotation of the cam latch causes a linear motion of the plunger in a plane parallel to a component-mounting surface of the circuit board, thereby facilitating locking and unlocking of the circuit board.

An electronic assembly including motherboard, first slide rail, second slide rail, expansion card and engagement component. Motherboard includes main circuit board and first connector. First and second slide rails are fixed on main circuit board. First slide rail has first engagement hole. Expansion card includes expansion circuit board and second connector. Expansion circuit board is disposed on first and second slide rails and has first positioning recess. Second connector is plugged into first connector. Engagement component includes connecting portion, first movable end portion, second movable end portion, first protruding portion, and second protruding portion. First and second movable end portions are respectively connected to two opposite sides of connecting portion. First protruding portion protrudes from first movable end portion and is removably engaged with first positioning recess. Second protruding portion protrudes from second movable end portion and is removably engaged with first engagement hole.

An electronic device having slots into each of which a circuit board is inserted includes faceplates attached respectively to the circuit boards on the side of an extraction direction. The faceplates each include two handle portions that are disposed respectively at both ends of a main body in the width direction and that extend in the extraction direction. The handle portion of one of two faceplates adjacent in the width direction that is located closer to the other of the faceplates, and the handle portion of the other faceplate that is located closer to the one faceplate, have respective distal ends shifted from each other in a thickness direction.

An adaptor for incorporating a function of an Open Compute Project (OCP) mezzanine card into a storage device includes a framework, a baseboard mounted to the framework and arranged to have the Open Compute Project (OCP) mezzanine card mounted thereon, an adapting part on the baseboard, the adapting part including an insertion slot for receiving a first interface of the OCP mezzanine card, and a connector on the baseboard, the connector configured to connect with the storage device, the baseboard including interconnections between the connector and the adapting part to provide for data exchange between the OCP mezzanine card and the storage device.

A configurable lock device is disclosed. The configurable lock device includes a first latch base, which includes at least two receiving spaces. The two receiving spaces are configured to receive a latch device to secure a computer expansion card. The configurable lock device also includes a connecting element separating the at least two receiving spaces.

An electronic control device includes: an electronic circuit board on which an electronic component is packaged; and a housing in which the electronic circuit board is contained, and which is composed of a case and a base. The electronic control device includes: a plurality of claws which is provided in the case of the housing and fixes the electronic circuit board; a fixing groove which is formed in the case on the rear side of the claws, and into which a peripheral edge portion of the base is close-fitted; a cutout which is formed on the rear side of the claws of the housing and is communicated with the fixing groove; and adhesive which is filled on the rear side of the claws via the fixing groove and the cutout.
