Therefore, bonding is considerably difficult in normal air, and the bonding strength becomes low. In addition, heat is transferred to the shape memory portion 7 of the thermal sensor body 6 during the joining process, and the thermal sensor body 6 starts to operate and deforms. Therefore, after the thermal sensor body 6 is cooled, the shape is returned to the original shape at room temperature. However, there is a problem in that it requires time and labor for processing, and the manufacturing cost of the device is significantly increased.

いる。As shown in FIG. 2, a stainless tie wrap 5 is made to cross at the center of the thermal sensor body 6 in a cross shape, and these overlapping portions are bonded with an acrylic adhesive to form a joint portion 11.
And In this example, the bonding portion 11 is attached using a two-liquid mixing type acrylic adhesive composed of a main agent and a curing agent in the following procedure. First, an appropriate amount of acrylic adhesive obtained by mixing and stirring equal amounts of the main agent and the curing agent in advance is dropped at the position of the joint portion in the center of the back surface of the thermal sensor body 6. In this way, the portion of the stainless steel tie wrap 5 to be joined is gently placed so as to be orthogonal to the portion of the thermal sensor body 6 on which the adhesive is filled. Thus, as shown in FIG. 2, the joint portion 11 between the thermal sensor body 6 and the stainless tie wrap 5 is adhered by a thin film of adhesive, and excess adhesive wraps around the surface side of the stainless tie wrap 5 through the engaging holes 12. , To form a strong bridge and combine. The curing reaction of the acrylic adhesive composed of the main agent and the curing agent used here is completed within a few minutes. Therefore, this joining operation is extremely easy, and a large number of joining operations can be performed quickly. In this example, as the acrylic adhesive, a commercially available adhesive manufactured by ThreeBond Co. (trade name: ThreeBond 3920B / 3925B, ThreeBond 3921 /

The experimental results compared with those of the conventional coupling means will be described. As a conventional coupling means, a copper tape fixing body which is mainly used in conventional products is used. As the strength of the bonded portion, the shear peel strength is taken into consideration. The measurement method was such that the stainless tie wrap 5 was fixed and a shear force was applied to both arms of the thermal sensor body 6 by using a spring balance (weighing 10 kg). At this time, the area of the joint is 54 m

In addition, the shape memory portion 7 does not rise, and the performance can be remarkably improved as compared with the conventional heat detecting device using the fixing means. It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various other configurations can be adopted without departing from the scope of the present invention.

There is an effect that it is possible to eliminate the fear that the joint portion will be broken during normal handling of the heat generation detection device or during handling until the heat generation detection device is attached to the object to detect heat generation. In particular, in the case where the adhesive has an adhesive structure in which the adhesive wraps around from the adhesive surface side to the outside of the outer surface through the fastening holes of the tie wrap to form a bridge of the adhesive, the thermal sensor body and the tie wrap are Since the bonding force of the bridge portion is added to the adhesive force between the joint surfaces of 1), there is an effect that the strength of the coupling portion can be further increased.
