A frame module is provided, which is adapted to connect to an object unit. The frame module includes a module housing, a latch, and a cover. The object unit is connected to the module housing. The latch is connected to the module housing, which is adapted to be moved between the first latch position and the second latch position. When the latch is in the first latch position, the latch is connected to the object unit to restrict the object unit. When the latch is in the second latch position, the latch is separated from the object unit. The cover pivots on the module housing, which is adapted to be rotated between the first cover orientation and the second cover orientation. When the cover is in the first cover orientation, the cover presses the latch and keeps the latch in the first latch position.

An extension mechanism includes a bracket, a carrier, a slidable member, and a covering plate. The bracket includes a plurality of first buckling portions and a plurality of second buckling portions. The carrier is configured to move along a first axis relative to the bracket. A fastening portion of the carrier is configured to clamp one of the first buckling portions. The slidable member moves in a sliding groove of the covering plate along a second axis. A hook portion of the slidable member is configured to clamp one of the second buckling portions. The covering plate is connected to the slidable member and stops an extension module located on the bracket, to prevent the extension module from dropping or loosening when the extension module is vibrated.

An electrical connector assembly includes an electrical connector and a CPU. The electrical connector includes an insulative housing defining a receiving cavity, and a plurality of contacts retained to the housing with corresponding contacting sections exposed in the receiving cavity. A first securing piece is attached upon the CPU, and a second securing piece is attached upon the housing. When the CPU is received within the receiving cavity, the first securing piece is locked with the second securing piece so as to have the CPU retained to the connector in position wherein the corresponding contacts of the electrical connector are mechanically and electrically connected to the corresponding contacting pads of the CPU in a compression manner reliably.

Electronic device fastening systems that enable one or more electronic devices to be reliably and quickly secured on a host board and electronic systems made of the same. In a specific exemplary embodiment, a retainer clip spans across the width of one or more electronic devices, engages with the board and snaps into place. The clip includes one or retaining posts such that when the clip engages the board, the one or more retaining posts align and engage with a predefined mounting feature of a corresponding one of the one or more electronic devices, thereby securing the electronic device in place to restrict horizontal, lateral, and vertical movement of the electronic 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.

A frame module is provided, which is adapted to connect to an object unit. The frame module includes a module housing, a latch, and a cover. The object unit is connected to the module housing. The latch is connected to the module housing, which is adapted to be moved between the first latch position and the second latch position. When the latch is in the first latch position, the latch is connected to the object unit to restrict the object unit. When the latch is in the second latch position, the latch is separated from the object unit. The cover pivots on the module housing, which is adapted to be rotated between the first cover orientation and the second cover orientation. When the cover is in the first cover orientation, the cover presses the latch and keeps the latch in the first latch position.

A wireless transmitting device comprising a base, a circuit module, a supporting member and a casing is provided. The base comprises a main body and an extending portion integrally connected with the main body. The main body has a cavity. The circuit module is partially accommodated in the cavity. The supporting member props the circuit module and connects with the extending portion. The casing connects with the extending portion or the supporting member and covers the extending portion, the circuit module and the supporting member.

Latches for securing circuit board assemblies within a slot of a telecommunications chassis are provided. In one embodiment, a latch for restricting motion of a substrate with respect to a fixed component within a slot of the telecommunications chassis is described. For example, the latch may include a mounting section allowing the latch to be mounted to the substrate. The latch may also include a cantilever section and an arc section connecting the mounting section to the cantilever section. Furthermore, the latch may include a retention component extending from a surface of the cantilever section. The retention component may be configured to restrict motion of the substrate when engaged with the fixed component within the slot.

A fastening device for expansion cards that is capable of connecting to a slot on a normal motherboard and fastening an expansion card in the slot is disclosed. The fastening device includes a top pressing unit and two side fastening units, wherein the two side fastening units are connected to two ends of the top pressing unit, respectively, and each side fastening unit is provided with an opening. When two clip units disposed on the two ends of the slot pass through the openings of the two side fixing units respectively, the top pressing unit presses the top edge of the expansion card inserted into the slot and the two side fastening units respectively press and fasten the two clip units so as to restrain the clip units from unlocking and to prevent the expansion card from becoming loose in the slot.

A chassis device adapted for an expansion device is provided and includes a case, a base and a latch. The case includes an avoiding portion. The base is disposed on the case. At least one accommodating portion is formed on the base. The latch includes at least one pivoting portion, a first abutting portion and a second abutting portion. The at least one pivoting portion is movably disposed through the at least one accommodating portion. The latch is slidable between a locking position and a non-locking position. The first abutting portion and the second abutting portion respectively abut against the case and the expansion device when the latch is located at the locking position, and the avoiding portion allows the latch to pivot when the latch is located at the non-locking position. Besides, a server including the aforementioned chassis device is provided.
