A display device includes a display module including a first area and a second area adjacent to the first area. At least a portion of the second area is curved with a constant degree of curvature. A flat support is disposed under the display module and overlapping the first area. A plurality of segments are disposed under the display module, overlapping the second area, and each having a structure including a plurality of laminated plates.

A system may include a plurality of rack-mountable, ruggedized drawers, each comprising a main body, a set of fans, a power supply, and a card connector. Connections may be provided, via a backplane of each of the card connectors, to a set of plugin cards each installed in the respective main body. A processor of the card connector of one of the drawers may represent the drawers by communicating information with an external third party.

A back cover module adapted to be disposed on a casing having a back opening is provided. The back cover module includes a fixing bracket, a sliding bracket and a rotating mask. The sliding bracket is slidably disposed on the fixing bracket along a first direction. The rotating mask is pivoted to the sliding bracket. When the fixing bracket is fixed to a position of the casing adjacent to the back opening, the fixing bracket and the sliding bracket are adapted to be inside the casing and a portion of the rotating mask is exposed from the casing. The rotating mask is adapted to follow the sliding bracket and move relative to the fixing bracket toward the first direction to a position out of the casing, and is adopted to rotate relative to the sliding bracket and shield the back opening after being moved out of the casing.

Embodiments of the present disclosure disclose an antenna, and relate to the field of wireless communications. In the antenna, radiation parts of the antenna are disposed on at least two layers of circuit boards on a printed circuit board: a top layer circuit board and a first layer circuit board, so that lengths of the radiation parts of the antenna are reduced, and space occupied by a printed wire of the antenna on the PCB is reduced. Therefore, reducing a PCB size becomes possible, a size of a terminal using the reduced-size PCB may also be correspondingly reduced, and the terminal may be further miniaturized.

The disclosure provides a server including a housing, a plurality of hash boards, a power module and an electrical connection board. Each hash board is slidably arranged in a first accommodating space. The plurality of hash boards and the power module are respectively connected to the electrical connection board. The power module supplies power to the plurality of hash boards through the electrical connection board. The electrical connection board includes two conductive connection boards, each of which is provided with a plurality of conductive pins. The pins form multiple pairs of conductive pins in one-to-one correspondence. Each pair of conductive pins corresponds to each hash board and is electrically connected to supply power to the hash board. Each pair of conductive pins is detachably matched with each hash board to connect or disconnect the power supply path of the hash board.

A modular I/O device includes a terminal base with a terminal block that includes a plurality of wiring connectors. An auxiliary wiring device includes a plurality of auxiliary wiring connectors and is selectively physically connectable to the terminal base in an operative position and selectively physically removable from the terminal base. The terminal block includes a receiver and the auxiliary wiring device includes a body including at least one mounting tab that projects outwardly from the body and that is located in the receiver. The receiver includes a projecting lip about which the auxiliary wiring device is pivotable relative to the receiver on a pivot axis. The terminal base includes at least one catch and the auxiliary wiring device further includes at least one latch arm that is adapted to engage the catch when the auxiliary wiring device is physically connected to said terminal base in its operative position.

A transmission device includes a housing, and a plurality of plug-in assemblies mounted in the housing, wherein each of the plug-in assembly that executes signal transmission and includes a board, heat generating parts mounted over the board and a fan that cools the heat generating parts.
