Some embodiments described herein relate generally to plug adapters, specifically to reconfigurable plug adapters.
Permanent electrical and other outlets typically include a limited number of outlets usable to plug in devices requiring electrical power, or requiring access to a signal path to and/or from a signal source. When more outlets are needed, a plug adapter can be coupled to a permanent outlet, which increases the number of outlets available. However, the outlets on such plug adapters may be oriented so that devices such as power adapters having large housings in fixed orientation with respect to their electrical plugs can obstruct some of the outlets, reducing the benefit of the plug adapter. Furthermore, the length and/or width of the plug adapter can limit the locations where the plug adapter can be placed.
Thus a need exists for a reconfigurable plug adapter.
In some embodiments, an apparatus provides an electrical signal path between an electrically conductive portion of a device plug and a signal port. The apparatus includes a first housing segment having a longitudinal axis. The first housing segment includes a first receptacle configured to receive at least the electrically conductive portion of the device plug and a signal port coupler configured to selectively conductively engage with the signal port. The apparatus includes a second housing segment having a second receptacle configured to receive at least the electrically conductive portion of the device plug. The second housing segment is coupled to the first housing segment for movement relative to the first housing segment about the longitudinal axis of the first housing segment.
As used in this specification, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, the term “rotation boss” is intended to mean a single rotation boss or a combination of rotation bosses.

An alternative implementation of a plug adapter is described in detail below. This implementation is an electrical power adapter, specifically, a 120 volt, 3 prong plug adapter and a data adapter, specifically, a universal serial bus (USB) adapter.
Each of the components of the plug adapters discussed herein can be monolithic or a combination of parts. By way of example, with reference to
While various embodiments have been described above, it should be understood that they have been presented by way of example only, not limitation, and various changes in form and details may be made. While the plug adapters are shown and described as having a certain number of segments, in some embodiments, more or fewer segments can be included. While the plug adapters are shown and/or described as having certain configurations (i.e. closed, partially open, and fully open), in some embodiments, the plug adapters can have virtually any configuration based, at least, on the number of segments and/or characteristics of the segments. While the segments are shown and/or described as rotating about a single axis, in some embodiments, the segments can move relative to one another in more than one plane and/or axis, such as, for example, twisting about an axis perpendicular to a plug face, bending about an axis perpendicular to a plug face, translating along an axis, and/or combinations of such relative movements.
While shown and/described as a 120V three prong plug, any of the plug adapters described herein can be configured for other power sources, audio, video and/or data sources, or combinations of sources, such as, for example, universal serial bus (USB), Fire Wire, international power standards, etc. In such embodiments, the plug adapter and associated segments can have more or fewer signal paths, and more or fewer associated components in accordance with the signal requirements, such as, for example, connectors, tracks, insulation members, support members, etc. Furthermore, the components shapes and characteristics of the components can be modified based on the type of outlet/plug and the number of associated components. In some embodiments, a first segment can include a first plug type and a second segment can include a second plug type. By way of example, a base segment can include one or more universal serial bus ports, and an outer segment can include a 120V three prong plug.
Other aspects of the plug adapters shown and described can be modified to affect the performance and/or characteristics of the plug adapter. By way of example, in some embodiments, the range of relative motion can be defined by the size and/or shape of the rotation track, the size, shape, and/or number of rotation bosses, and/or the type of plug/outlet. Similarly, light ring 630 can be a uniform light source, non-uniform light source, can indicate on and/or off, etc. In some embodiments, a plug adapter can include a point light instead of, or in addition to, the light ring. By way of example, front housing 610 of base segment 600 can include an aperture configured to allow light from light source 631 to be visible through front housing 610. In such embodiments, the aperture can be fully or partially covered by a translucent, semi-translucent, and/or colored window. The color of the light visible through light ring 630 and/or the aperture can be based on light source 631, a color of a window covering the aperture and/or a color of light ring 630, and/or by a combination of the color of light source 631, the color of the window, and/or the color of light ring 630. The plug adapters can also include device protections, such as, for example, fuses, breakers, surge protection elements, etc.
Any portion of the apparatus and/or methods described herein may be combined in any combination, except mutually exclusive combinations. The embodiments described herein can include various combinations and/or sub-combinations of the functions, components and/or features of the different embodiments described.
