Temperature sensor

A temperature sensor comprising a pair of dissimilar metallic conductors electrically insulated one from the other along the lengths thereof but electrically connected at one of their ends to form a thermojunction, and a connector comprising an elongate backing strip of dielectric sheet material, the other ends of the conductors being positioned to extend generally transversely across one face of the strip and being spaced apart longitudinally of the strip, and facing strip means on the backing strip comprising a first facing strip of dielectric material on said one face of the backing strip overlying said other ends of the conductors, said first facing strip having openings therein exposing bare uninsulated portions of said other ends of the conductors to provide electrical contacts whereby on insertion of said connector into a mating connector said contacts are adapted to be engaged by corresponding contacts in the mating connector for making respective electrical connections.
