| Abstract: |
Disclosed is a heating device having a elongated body to heat an electric part for soldering or desoldering the electric part. The heating device includes a tip through which the heat is applied to the part, a heater for heating the tip and a temperature sensor for detecting temperature at the tip. The heater and the temperature sensor are longitudinally distant from each other. The temperature sensor is located in a forward portion of the body to be close to the tip. The heater includes a heater core of high heat conductive material, and a heating coil wound around the heater core, with heat being conducted through the heater core in the longitudinal direction of the body to the tip.

1. An electric heating device, having a substantially rod-shaped body for applying heat from an end portion of the body to an outside material, the heating device comprising: a tip for applying heat from the tip to the outside material; a heat generating member which is electrically energized to generate heat for heating the end portion of the body, the heat generating member including a heater core of high heat conductive material and a heating coil wound around the heater core, the heater core being coupled with the tip such that the tip and the core extend serially in the longitudinal direction of the body; a temperature sensor located within the tip to detect the temperature at the tip, the temperature sensor being located distant from the heat generating member in the longitudinal direction of the body; and a sensor insulating pipe located within the body between the heating coil and the temperature sensor along the longitudinal direction of the electric heating device to make the heating coil and the temperature sensor distant from each other, and a sensor lead wire connected with the temperature sensor and extending through the sensor insulating pipe.
