IPC: H05B3/14
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To restrain reduction in a heating value to long-term use by directly fixing an I-shaped heat radiator by continuously bending a thin metallic plate in an I shape to electrodes arranged on both surfaces of a thermistor, and fixing a metallic terminal assembly to the I-shaped heat radiator by a welding point. SOLUTION: Electrodes by flame spraying of aluminum are imparted to both surfaces of a positive temperature coefficient thermistor 11. An I-shaped heat radiator 12 is molded by continuously bending a thin plate of aluminum in an I shape, and a metallic terminal assembly 13 is fixed to this by a welding point 14.

Therefore, when the long side l3 of a bottom part of the heat radiator 12 is made shorter than the short side l4, dislocation by thermal expansion is hardly caused.  Moreover, since the I-shaped heat radiator 12 is used, reduction in a heating value so far is not caused.
