ABSTRACT:
A thermal detector in which an element unit has a heat sensor element such as a, thermistor, sealed into the terminal end portion thereof, for electrically detecting temperature change. A detector body integrates by plastic-forming a pair of fitting members for electrically and mechanically coupling to a detector base. A circuit board is mounted on a circuit accommodation portion inside the detector body. A back side cove is provided for closing and sealing the circuit accommodation portion from the reverse side thereof. Airtightness of the circuit accommodation portion is thereby secured and it is simplified to make possible automatization. Positioning projections and respective positioning grooves are provided. By respectively fitting these, positioning is achieved of the circuit board to a molded body, the back side cover to the reverse side of the molded body and the outer cover to the lower side of the molded body. In such a positioned state, the back side cover, the circuit board, the molded body and the outer cover are fixed into one body by screwing of the fitting members. Positioning of a plurality of component parts at the time of assembling is simplified thereby to achieve an improvement in working efficiency and assembling precision.
