Abstract

A heat generating curling implement includes a generally cylindrical body member about which hair may be wound and containing two heat radiating U-shaped plates with interlinking base portions with a positive temperature coefficient heating element sandwiched between the inside surfaces of the interlinked base portions. Each plate has two heat radiating legs. All legs extend substantially in the same direction. The legs of both plates partially co-extend. The interlinking base portions do not contact one another. An electrode pin is in electrical contact through a contact plate to one of the radiating U-shaped plates. The electrode pin does not extend through the PTC element and does not extend through the base portion of the radiating plate. An electrode ring surrounds the electrode pin and is electrically insulated therefrom and electrically connected to the other radiating U-shaped plates through a second contact plate.
