  • Publication number: 20130078867
    Abstract: Embodiments are directed to a duck head connector comprised of a connector for connecting to a power adapter and an electric plug that swivels about the face of the side of the plug, where flexible insulated wires connect the prongs of the electric plug with the contacts of the connector. The flexible insulated wires rotate together with the plug, with the length and shape of the wires enabling the wires to wrap around each other without becoming tangled. In an alternative embodiment, a pair of spring contacts connects the prongs of the electric plug with a pair of stationary half-ring contacts. The spring contacts swivel along the inner surface of the half-ring contacts when the plug rotates. Flexible insulated wires connect the stationary half-ring contacts to the contacts of the connector.
