Abstract
PURPOSE: To realize both a high performance and high durability, by coiling the resistance wire coated with the insulated film close on the outer circumference of a tubular or bar-type bobbin and then attaching the both ends of the resistance wire close the a pair of lead wires which are connected to the bobbin via the heat-resistant cement.
CONSTITUTION: The tubular or bar-type fernico-made bobbin 1 is welded to the lead wire 3 by the glass material. In this case, the glass material 2 is projected through the end part of the bobbin 1 to prevent the shift which is caused by coiling of the resistance wire 5. The both ends of the wire 5 are spot-welded or prssure- welded to the wire 3 at the joint 6. The resistance wire 5 made of the platinum wire is coated thin by the insulated film 4 and then coiled close to the bobbin 1 coated with the adhesive 7. The film 4 uses the polyimide, polysiloxane polymer or inorganic adhesive. And the alumina tube can also be used for the bobbin 1. In such way, a heating resistor having a high performance and high durability can be obtained.
