<p><P>PROBLEM TO BE SOLVED: To provide a waterproof type heat detector which can be assembled without needing to seal, for example, a through-hole for insertion of a temperature detection element of a detector body and the like by an adhesive, etc. and without waiting for an adhesive drying time in a heat detector assembly process. <P>SOLUTION: A heat detector 1 comprises: a circuit substrate 3 on which a temperature detection element 9 is erected; a circuit substrate housing case 7 of a bottomed frame body shape having an opening for housing the circuit substrate 3; and a detector body 13 having a through-hole 11 through which the temperature detection element 9 erected on the circuit substrate 3 can pass and a locking piece which serves as case fixing means for fixing the circuit substrate housing case 7. The circuit substrate 3 is housed in the circuit substrate housing case 7 such that the temperature detection element 9 projects from the opening 5 and the housing case is filled with a filler, with the temperature detection element 9 being made to insert into the through-hole 11. The circuit substrate housing case 7 is thus fixed to the detector body 13 by the locking piece. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
