An electric apparatus includes a substrate having a ground pattern on a top surface of the substrate; a conductive housing on the ground pattern and having an insertion space; a conductive connector disposed between the ground pattern and the conductive housing and connected to the ground pattern and the conductive housing, wherein the conductive housing is fixed to the substrate via the conductive connector; and a conductive cover coupled to the conductive housing, wherein the conductive cover is configured to move from a first position, at which the conductive cover externally opens the insertion space, to a second position, at which the conductive cover closes the insertion space.

An electronic device configured to be mounted in a housing of a cluster, the device comprising a rear body housing at least one mother board configured to be powered by the cluster, a front tray housing at least one electronic board having at least one socket, the front tray comprising at least one fastening member for mounting an expansion card having an edge connector and a fastening portion, the electronic board being connected to the mother board by at least one flexible cable, the front tray being mounted slidable relatively from the rear body between a close position and an open position in which the front tray is at least partially removed from the cluster housing while keeping the rear body into the cluster housing so that an expansion card can be mounted/unmounted from the electronic board without powering off the device.

An electronic device is provided. The electronic device includes a board, a first latch mechanism, and an expansion card. A controller is disposed on the board. The first latch mechanism is disposed on the board. The first latch mechanism is electrically connected to the controller. The expansion card is plugged in the first latch mechanism and disposed over the board. The expansion card is electrically connected to the controller through the first latch mechanism. The controller determines a connecting condition of the first latch mechanism according to a connecting signal provided by the expansion card.

The present disclosure provides an electronic badge and a housing for the same. The housing includes: a rear case defining a main board cavity, and formed with a display opening in communication with the main board cavity and a profile card receiving slot located outside the main board cavity; and a front case detachably disposed on the rear case to enclose the profile card receiving slot or both the display opening and the profile card receiving slot, a portion of the front case opposite the profile card receiving slot or both the display opening and the profile card receiving slot being made of a transparent material.

A portable interface system comprising an interface device and a portable base part, wherein the interface device is fixable detachably without tools in an attachment area of the base part and wherein the interface system is designed in such a way that the interface device is activated if the interface device is detached from the base part.

Systems and methods are provided for retrofitting a Wi-Fi sensing module into a housing of a switch or socket. A cover is removed from the housing to reveal a space comprising an electrical wire. A Wi-Fi sensing module is inserted into the space and connected to the electrical wire. The cover is then secured to the housing to fully conceal the Wi-Fi sensing module.

A server includes a chassis and an electronic device assembly. The electronic device assembly includes a holder and a fixing member. The holder accommodates an electronic device and includes a limiting slot and a positioning hole. The fixing member includes a hook set. The hook set includes a first hook and a second hook. The first hook is connected to the limiting slot to be limited in a first direction. The second hook is connected to the positioning hole to be limited in a second direction. The first direction is substantially different from the second direction. The fixing member and the holder sandwich a connector connected to the electronic device.

An electronic device includes a casing and an expansion card. The casing includes a chassis and an installation frame. The installation frame is pivotably disposed on the chassis. The expansion card is fixed to the installation frame. The expansion card is movable along with the installation frame so as to be located in the chassis or at least partially located outside the chassis.

A server device includes a case, first, second and third hard disk brackets and a first cable management cover. The case includes a main part and an expansion part disposed on the main part. The first hard disk bracket is fixed to the expansion part. The second and third hard disk brackets are pivotably disposed on the main part. A first cable management space is formed between each of two opposite exterior surfaces of the second hard disk bracket and each of two opposite interior surfaces of the main part. The second hard disk bracket is between the first and third hard disk brackets. A second cable management space is between a bottom surface of the third hard disk bracket and a supporting surface of the main part. A first cable management cover is in one of the first cable management spaces and fixed to the main part.
