自己制御型セラミツクグロープラグ。 A ceramic heater is used in which a heating wire made of a high-melting point metal is embedded in a ceramic combustor, and a resistor is connected in series to the heating element within the inner cavity of the mounting fitting. , this resistor coil is arranged in a metal tube with both ends open, and within the tube, one end of the resistor coil is connected to the tip of the center shaft protruding from the rear end of the mounting bracket, and the other end is connected to the heating element. The resistor coil and the connecting portion are embedded in a heat-resistant insulating material filled in the inner cavity of the tube to form an integrated assembly, and the metal of the assembly is In a self-regulating ceramic glow plug that has a structure in which the tube is fixed to the inner cavity of the mounting bracket by caulking from the outer periphery with a part of the body of the mounting bracket, the assembly in the inner cavity of the mounting bracket is attached to the coil-embedded portion of the resistor. 0.01 to 0.6 between the outer circumference of the metal tube and the inner surface of the mounting bracket
The metal tube is housed with a gap of 1.5 mm between the metal tube and the metal tube is fixed by caulking with a part of the mounting bracket from the outer periphery of the buried part of the center shaft in the middle part separated from the buried part of the resistor coil. Self-regulating ceramic glow plug.
