PTC hair roller

An electric hair curler comprising:

• a cylindrical hollow housing;
• a PTC heating element;
• first and second U-shaped members each having two legs and a base portion and composed of a material that conducts heat and electricity and each disposed inside the cylindrical hollow housing, said base portions positioned in linking relationship through the use of an end spacer having locating pins corresponding to apertures in the base portions such that the legs of the first U-shaped member and the legs of the second U-shaped member are in heat exchange relationship with the housing and extend in the same direction from their respective base portions substantially in a common direction and the heating element is sandwiched between said base portions in electrical and heat conducting relationship thereto;
• means on said housing electrically connected to the U-shaped members to supply electricity to the heating element.

A method of assembling a contact assembly comprising the steps of:

• providing a U-shaped contact plate and a folded contact plate each having an aperture therein and two legs;
• arranging said contact plates such that all of said legs extend substantially in the same direction with the legs of said first plate at least partially coextending with the legs of said second plate;
• linking the contact plates such that the contact plates are electrically insulated from each other;
• electrically attaching an electrode pin to the first contact plate so that the pin extends along the length of the legs of the first contact plate;
• and
• electrically attaching a contact ring to the second contact plate so that the contact ring extends along the length of the legs of the second contact plate and said ring surrounds said pin and is electrically insulated therefrom.
