An electronic module adapted to an electronic apparatus is provided. The electronic apparatus includes a casing and an electronic assembly, and the electronic assembly is disposed on the casing. The electronic module includes at least one electronic component, a carrier, a rotation component, a connection component, and an elastic assembly. The carrier carries the electronic component, and the carrier is arranged on the casing. The rotation component is pivotally connected to the carrier. The connection component is connected pivotally to the rotation component. The elastic assembly is disposed on the connection component and a hook portion is disposed thereon. The hook portion is adapted to be hooked to the casing, such that the electronic component is plugged to the electronic assembly by the elastic assembly.

An electronic module assembly is provided. The electronic module assembly may include one or more processors mounted to a laminate, a top frame mounted to the laminate and surrounding the one or more processors, and a removable lid covering the one or more processors. The removable lid includes latches arranged along a perimeter of the removable lid, the latches engage with a lip of the top frame and secure the removable lid to the module assembly, and the removable lid can only be removed from the module assembly by releasing all of the latches.

The present invention provides a charging stand includes a base, a housing, a circuit board, and a rotatable connector. An upper surface of the housing is formed with an opening. A plurality of sidewalls of the housing are engaged with a periphery of the base, and the housing has an accommodation space inside. The circuit board is disposed on the base. The circuit board is contained in the accommodation space in the housing, and suitable for being connected to an external power supply. The rotatable connector is pivotally connected to the base. The rotatable connector is electrically connected to the circuit board, and is contained in the accommodation space in the housing and visible from the opening.

A current transformer includes a first housing including a first handle portion and a first distal portion, a second housing including a second handle portion and a second distal portion, a first core having a first proximal core end and a first distal core end the first core mounted in rotational contact within the first distal portion, and a second core having a second proximal core end and a second distal core end, the second core mounted in rotational contact within the second distal portion, wherein the first housing is rotationally coupled to the second housing about a fulcrum point.

A safety device for medium-high voltage system is disclosed and includes a cabinet, a power module and a metal cover plate. The cabinet includes an accommodation seat connected to the medium-voltage charged region and having an opening. The power module is detachably disposed in the accommodation seat through the opening. The metal cover plate is pivotally connected to the accommodation seat and grounded. When the metal cover plate is in the first position, the opening is closed and the medium-voltage charged region is shielded. When the power module is set in the accommodation seat, the metal cover plate is pivotally rotated to a second position, and the power module is electrically connected to the medium-voltage charged region. When the power module is detached from the accommodation seat, the metal cover plate is rotated to the first position, and the opening is closed to shield the medium-voltage charged region.

An electronic device and an unlocking cover thereof are provided. The unlocking cover includes a shield, at least one assembling portion, and at least one abutting portion. The shield has a baffle and a shielding board that is connected to the baffle. The at least one assembling portion extends from the baffle. The at least one abutting portion extends from an inner surface of the shield. A distal end of the at least one abutting portion away from the shielding board is spaced apart from an inner surface of the shielding board by a triggering height that is within a range from 3.5 mm to 9 mm.

Embodiments of the present invention are directed to systems, devices, lockable enclosures, and methods for data centers. In one example, a lockable enclosure for a data drive is provided. The lockable enclosure includes a housing configured to retain a first data drive and a latch contained within the housing and configured to receive a second data drive, wherein the latch is configured to move within the housing for dispensing the first data drive from the housing while the second data drive remains secured therein.

A space-saving locking device for a server cabinet which does not present sharp edges to a user during handling locks a first housing to a second housing and includes first and second locking members. The first locking member includes a clamping portion with one end defining a latching slot, the second locking member includes a locking portion matching the latching slot. When the first locking member is operated, the locking portion is latched to the latching slot, and the first locking member is locked to the second member.
