A reel device is a casing device for rollingly storing wire. The casing has a turnplate and is coupled with a measuring model. The measuring model has a function of testing the external circuit or power source plug and providing warning or presenting information regarding the external circuit or power source plug.

The invention is an oblong cable spool with an internal perimeter defining a hollow that is disposable to retain a rigid portion of a device-cable assembly, such as an ear-bud assembly, where the cable can be spooled around a spooling surface, making the combined assembly of spool and device-cable assembly suitable for the compact organization, spooling, storage and transport of a device-cable assembly.

The invention is a circular cable spool with an internal perimeter disposable to retain a power adaptor at its distal portions by friction fit. In most embodiments, sidewalls of the spool will extend axially and distally from opposite ends of the circular spooling surface, disposed to spool and retain a cable between them. Power adaptors intended for electronic devices are, in general, nominally square or rectangular in profile (typically box-like in volume), whether the corners of the adaptors have radii or not. In order to retain a square power adaptor within a round interior perimeter, the adaptor must be held at its distal portions by friction, generally at its corner portions, to the interior perimeter of the spool. Accommodations in the design of the cable spool allow the tangs of the power adaptor to straddle the spool, by limiting the thickness of the spool to fit between the tangs, as provided by a radius between the interior perimeter and a sidewall, and further by including a relief slot in a sidewall or interior perimeter that facilitates insertion of the adaptor within the interior perimeter of the spool. Accommodating the tangs to fit around the spool in such as manner in measure to facilitate the assembly of the adaptor within the interior perimeter provides a more compact assembly, desirable for transporting portable devices and their cables and adaptors together in an organized fashion.

In general, in one aspect, one or more examples relate to apparatuses and methods for deploying a cable. The apparatuses comprises a set of spools. Each spool includes a pair of flanges, and a cable hub positioned between them. The cable hub defines one or more module compartments configured to house modules. A cable is wound around the hub, with at least one module contained within the module compartments and connected to a first end of the cable.
