An electronic device includes a first body, a pivot assembly and a second body. The first body includes a first side and a second side, and the second side includes a groove. The pivot assembly includes a container, a first gear, a second gear and a third gear. The container includes an accommodating space and a side wall. The first gear is disposed in the accommodating space and connected to the groove. The second gear is disposed in the accommodating space, pivotally disposed at the side wall and engaged with the first gear. The third gear is disposed in the accommodating space, pivotally disposed at the side wall and engaged with the second gear. The second body is pivotally disposed at the container and connected to the third gear.

A method of adapting an electronic equipment structure for cable management, the method comprising: providing a cable manager having one or more cable finger units extending from a frame, the frame including at least one spine member having an extruded construction and one or more ledges that extend along a length thereof; providing an accessory rod assembly having a base member and an accessory rod, wherein the base member includes a front-facing socket, a rear-facing hook, and a rotatable knob having a threaded end received within a threaded portion at a side of the base member, and wherein the accessory rod has an extruded construction and a generally uniform, at least partially cylindrical, cross-sectional shape; positioning the rear-facing hook of the base member against one side of the one or more ledges of the at least one spine member; rotating the rotatable knob such that the threaded end is wound within the threaded portion of the base member and bears on an opposite side of the one or more ledges of the at least one spine member, thereby clamping the at least one spine member between the rear-facing hook and the rotatable knob; and positioning a proximal end of the accessory rod within the front-facing socket of the base member such that the accessory rod extends therefrom into a cable management space.

Systems, apparatus, methods, and techniques of assembly of discrete modules of a control panel are disclosed. The modules can be independently wired, tested, and installed into a control panel. Module definitions are defined specifying components to perform the electrical function, a mechanical arrangement of the components, electrical connections, and logical interactions of the module. A bill of materials can be generated based on a designation of a set of modules for a control panel and the module definitions. Modularly assembled control panels are disclosed. An assembly frame is described herein for temporarily mounting components of a module for independent assembly of a control module and for eventual removal and installation into a control panel frame. The assembly frame may include a faceplate frame and side frames and temporary mounting features.

Motor control centers have units or buckets with an extendable/retractable power connection (stab) assembly and one or more operating lever interlocks that include a unit latch to latch to a cabinet and a power connection position interlock that blocks the handle of the units or buckets based on position of the power connection assembly, optionally also including a shutter cam that slides a shutter right and left.

In one embodiment, an apparatus includes a fan tray comprising a plurality of fans for cooling modules within a modular electronic system with airflow from a front of the modular electronic system to a back of the modular electronic system, and a hinge member for connecting the fan tray to a front panel of the modular electronic system with the fans positioned in front of the modules. The fan tray is rotatable on the hinge member for movement away from the front panel to allow for replacement of one of the modules.
