ABSTRACT:
A rotary connector for electrically connecting a set of headphones to a portable personal audio device to help prevent stress on the electrical wires of the set of headphones. The rotary connector includes a substantially hemispherical jack socket defining a substantially hemispherical jack space. The outer surface of the jack socket has an annular primary contact therearound. The inner surface of the jack socket has a secondary and tertiary contacts. A resiliently deflectable top cup defines an upper space and has an interior surface with an annular first contact therearound. The top cup has an axial extent outwardly extending from the exterior surface of the top cup with an axial bore extending between the interior and exterior surfaces of the top cup. A generally spherical plug has an outwardly extending axial shaft which inserted into the axial bore of the top cup. The lower region of the plug is inserted into the jack space of the jack socket so that the plug is rotatable in the jack space of the jack socket about the center axis of the plug. The first contact of the top cap and the primary contact of the jack socket abut one another such that the first and primary contacts are in electrically communication with one another. The plug has second and third contacts which abut the secondary and tertiary contacts respectively such that the respect associated contacts are in electrically communication with one another.
