Abstract: An electrical connector includes a male connector and a female connector. The male connector has a housing, a first tubular conductor, a second tubular conductor, and an inner conductor. The first tubular conductor is carried by the housing and has an exposed first cylindrical contact surface. The second tubular conductor has an exposed second cylindrical contact surface of a smaller diameter than the first cylindrical contact surface. The inner conductor has an exposed contact surface that has a smaller diameter than the second cylindrical contact surface. The female connector has a non-conductive female connector housing and three electrical contacts carried by the female connector housing. Each of the three electrical contacts electrically connect, with the male connector engaged with the female connector, to a respective one of the contact surfaces of the male connector.

Abstract: An associated set of hair styling appliances is electrically powered by a single power cord, reducing cord clutter in salon workstations. When not in use the appliances are stored in an electrically powered appliance rack that preheats hair irons and other heated appliances. A method of styling hair features connecting the single power cord to one of the appliances to style hair in a first sense, then disconnecting the power cord from the appliance and connecting the cord to another of the appliances to style hair in a second sense.
