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.

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.

Heat dissipation device for an electronic board comprising a support body connected to the electronic board, said electronic board being provided with an electric connection interface which can be inserted into/extracted from an electric connector provided in a direction orthogonal with respect to the lying plane of a support plate, having a heat dissipation surface configured to dissipate the heat transmitted to it by thermal conduction, wherein said heat dissipation device comprises at least one holding element and a leveling member, coordinated with respect to each other in order to position a surface of the support body in contact with the heat dissipation surface of the support plate.

A case structure includes: a case having an opening at one end side; a cover configured to close the opening; and a pressing and holding portion configured to press and hold a board against the case when the cover applies a force to the board in a state where the board is accommodated in the case and the cover is closed.

A detection system for non-standard connection interface through an adapter card. In the detection system, snaps of a first assembly are inserted through fastening slots of an adapter card, to make the first assembly and the adapter card fasten and engage with each other; the snaps of the first assembly are further inserted through engaging slots of a second assembly, to make the first assembly, the adapter card and the second assembly engage and fasten with each other; a motherboard is electrically connected to the adapter card, and the adapter card is electrically connected to a standard test adapter card, and the standard test adapter card is electrically connected to a standard BSI development test fixture, thereby achieving the technical effect of restraining protection for the adapter card and improvement of stability in detection for the non-standard connection interface.

A connector assembling structure is provided. The connector assembling structure includes a shell, a circuit board, a connector, a fixing member, and an elastic member. The circuit board is disposed on the shell. The connector is disposed on the circuit board. The fixing member is fixed on the shell. The elastic member is disposed on the fixing member. The circuit board includes a pillar. The fixing member includes a fixing member opening corresponding to the pillar. The pillar passes through the fixing member opening. The size of the fixing member opening is greater than the size of the pillar, such that the circuit board and the elastic member may move relative to the fixing member through the fixing member opening.

A rotating buckle includes a first fixing member, a second fixing member, and a hook body. The first fixing member includes protruding posts. The second fixing member defines limiting slots and comprises a fixing portion. The fixing portion fixes the second fixing member to the first fixing member through a first resilient member. The hook body is received between the first fixing member and the second fixing member. The hook body defines a mounting hole, an inclined slot, and a receiving slot. The protruding posts are inserted through the mounting hole, the inclined slot, and the limiting slots. The fixing portion is inserted through the receiving slot. The hook body is fixed to the first fixing member through a second resilient member.

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 clamp may include two substantially planar plates opposite from and generally parallel to one another, each plate having a mounting hole formed therein for receiving a fastener, two teeth, each tooth extending from a respective one of the two plates, such that each tooth is generally perpendicular to the plates, and such that each tooth extends towards the other from its respective plate, and a tongue opposite from and mechanically interfaced between the two plates, such that the tongue has a concave curved profile between the plates, and such that when a force is applied in a first direction by a fastener engaging with the clamp through the mounting holes, compression of the plates towards one another causes deflection of the tongue in a second direction substantially perpendicular to the first direction.
