A hairsetter designed to heat a plurality of hair rollers to a predetermined temperature is provided with a plurality of sockets each intended to receive a single hair roller having a pair of electrical plug members axially extending from one end of the roller. The plug members are tapered along substantially their entire length and are formed as extensions of parallel longitudinally extending heat sinks engaging the sides of a PTC resistance heating element within the hair roller. Each socket is provided with a pair of contact pins. The upper portion of each pin is accessible through the top of the socket and the lower portion thereof is in contact with an electric wire to conduct power to the pin. The contact pins are separated by diametrically opposed ribs which interact with the tapered plug members to cause the hair roller to be automatically rotated as it as inserted into the socket so as to cause the plug members to firmly engage the upper portion of the contact pins.

In a hairsetter for electrically heating at least one hair roller, each said hair roller having an electrically activated internal heat generating material and a pair of plug members operatively electrically connected thereto and extending into a recess within one end of said roller, said hairsetter

In a hairsetter for electrically heating at least one hair roller, each said hair roller having an electrically activated internal heat generating material and a pair of plug members operatively electrically connected thereto and extending into a recess within one end of said roller, said hairsetter having at least one electrical socket member, each socket member including a pair of electrical contact pins receiving said pair of plug members, and means for completing an electrical connection between said contact pins of said socket member and a source of electrical power, the improvement wherein: each said socket member comprises an electrically insulated socket housing for receiving the end of said roller having said recess, said housing having a first hollow cylindrical portion with an outside diameter smaller than the inside diameter of said recess and having a second cylindrical portion concentrically aligned within said first cylindrical portion in spaced relation to the inner surface thereof to form an annular space therebetween, a pair of radially extending diametrically opposed rib members connecting said first and second cylindrical portions to form the annular space therebetween into two arcuate spaces, each adapted to receive one of said plug members one of said contact pens being inserted into each of into each of said arcuate spaces; and wherein each of said plug members is tapered to a point of predetermined radius at the distal end thereof, each said plug member having along its length a curved surface of substantially uniform radius of curvature, the concave sides of each of said curved surfaces facing each other and symmetrically situated about the longitudinal axis of said roller.
