  • Rotatable electrical connector for coiled telephone cord
    Patent number: 4583797
    Abstract: The low friction rotatable electrical connector is for use with a coiled telephone cord to prevent the cord from becoming twisted or tangled during use. This connector is generally of insulating material formed with a hollow housing for supporting a rotor assembly therein. This rotor assembly is a hollow cylinder that is positioned within the housing for relative rotation therein. One end wall of the housing has a circular opening in which one end of the rotor assembly is supported for rotation. The rotor assembly has a single longitudinal split for nearly the entire length thereof, but the split does not include the journal at one end that is located within the circular opening or bearing in the end wall of the housing. The rotor assembly supports a plurality of continuous conductive rings on the exterior thereof, and there is an insulating washer positioned between each pair of conductive rings to serve as a spacer between adjacent rings.
