A power apparatus includes a first power bus bar provided at a first power part, a second power bus bar provided at a second power part coupled to the first power part while communicating internally with the first power part, the second power bus bar being fastened to the first power bus bar, a first interlock bus bar provided at the first power part while being connected to an interlock terminal of a controller disposed within the first power part, a second interlock bus bar provided at the second power part while being fastened to the first interlock bus bar, and a safety cover fastened to a fastening portion between the first interlock bus bar and the second interlock bus bar while covering a fastening portion between the first power bus bar and the second power bus bar.

A system is provided. The system includes a computing resource, a cable insertable into the computing resource, a locking element and a controller. The locking element is configured to assume a locked condition in which the cable is locked to the computing resource or prevented from insertion into the computing resource and an unlocked condition in which the cable is removable from the computing resource and permitted to be inserted into the computing resource. The controller is configured to define rules for users. The rules are associated with respective identifiers (IDs) of each of the users and establish criteria associated with each user for causing the locking element to assume one of the locked and unlocked conditions.

Provided is a display device including at least one display assembly including a display module having a display panel displaying a screen in a first direction, and a supporter magnetically coupled with the display module and supporting the display module; wherein the display module includes a rotating magnet engaged with external magnetic force and rotated in a second direction perpendicular to the first direction, and an adjustment member engaged with rotation of the rotating magnet and translated in the first direction or a third direction opposite the first direction.

The present disclosure relates to electrical devices housed in a distribution box and, more particularly, to an interlock mechanism for visually indicating whether main contacts operated by the electrical devices are in an open condition or a closed condition.

A system and method are provided for coordinating the installation and removal a motor control center subunit with the power connection and interruption thereof. A system of interlocks and indicators causes an operator to install a motor control center subunit into a motor control center, and connect supply and control power thereto, in a particular order. Embodiments of the invention may prevent actuation of line contacts of the bucket, and shield the line contacts, until the bucket is fully installed in the motor control center. Other embodiments also prevent circuit breaker closure until the line contacts are engaged with a bus of the motor control center.

A port protector is provided for locking insert into a communication port of electronic equipment. The port protector comprises a base member defining a support surface extending longitudinally between outer and inner ends. The locking member is deflectively coupled to the base member by a spine member extending transversely therebetween. The locking member includes an anchored portion attached to the spine member and a plank portion projecting longitudinally inward therefrom to terminate at a free end, such that the plank portion extends over the support surface of the base member. An engagement member extends from the plank portion of the locking member and is configured for retentively engaging the communication port when disposed at a locking position therein. The engagement member is releasable from the locking position responsive to the spine member being severed to decouple the locking and base members from one another.

In some examples, an electronic device for mounting in a chassis includes a housing to be received in the chassis, and a mechanical intrusion indication segment to move from a retracted position to an extended position responsive to mounting of the housing in the electronic device. The mechanical intrusion indication segment when in the extended position is to break upon removal of the housing from the chassis. A controller is to detect an intrusion of the electronic device in response to breaking of the mechanical intrusion indication segment.

An interlock system for an enclosure can include a power switch movable between an OFF position and an ON position with a defeater arm coupled to the power switch. The defeater arm can be selectively movable between a locked position and an unlocked position and when the defeater arm is in the locked position the power switch is prevented from moving from the OFF position to the ON position. An interlock can include a pivot bracket pivotally supported by a support bracket within the interior of the enclosure and movable between a first orientation, in which the pivot bracket is out of engagement with the defeater arm, and a second orientation, in which the pivot bracket displaces the defeater arm into the unlocked position. When the door is moved into a closed position from an open position, a door bracket displaces the pivot bracket into the second orientation.

This is directed to connecting two or more elements using an intermediate element constructed from a material that changes between states. An electronic device can include one or more components constructed by connecting several elements. To provide a connection having a reduced or small size or cross-section and construct a component having high tolerances, a material can be provided in a first state in which it flows between the elements before changing to a second state in which it adheres to the elements and provides a structurally sound connection. For example, a plastic can be molded between the elements. As another example, a composite material can be brazed between the elements. In some cases, internal surfaces of the elements can include one or more features for enhancing a bond between the elements and the material providing the interface between the elements.

Provided is a Light Emitting Diode (LED) display device. The LED display device includes: a rectangle framework, including a frame, a first transverse beam and a second transverse beam arranged inside the frame at intervals, an adapter plate assembly, including a fixed plate mounted at a strip-like gap and an adapter plate detachably arranged on a rear side of the fixed plate, the fixed plate being provided with a lock, a display module, mounted on a front side of the rectangle framework through a magnetic attraction structure, a rear side of the display module being provided with a first strip-shaped lock hole, wherein, the lock includes a rotary shaft rotatably arranged on the fixed plate and a first lock tongue arranged on the rotary shaft, the first lock tongue is able to go through the first strip-shaped lock hole and has a first unlocking position corresponding to the first strip-shaped lock hole and a first locking position that is staggered with the first strip-shaped lock hole, and the adapter plate fits the display module through a connector in a plugging-in manner. The technical solution of the application effectively solves a problem that a display module in a related art falls due to separation from a box body.
