Abstract

PURPOSE: To enable accurate detection of the temperature of an object to be heated by connecting an electrode terminal having a heat collecting function to a lead of a thermistor while a heat collection plate is arranged closely on the electrode terminal and a thermistor element section to enhance heat response with a simple and inexpensive structure. CONSTITUTION: A glass sealed type NTC thermistor 3 is housed in the rear surface of a heat collection part 2a of an electrode terminal 2 and the tip of the heat collection part 2a is placed on a step part 15 provided in a recess part 1a of a holding body 1 while a lead connection part 2b is led outside from a through hole 1c. With such an arrangement, as an air layer serves as adiabatic layer between the thermistor 3 and the bottom surface of the recess part 1a, the conduction of a heater heat to the thermistor 3 is limited. In addition, conductors of a lead for supplying a power source can be piled and welded simply on a connection part 2b formed for a flat plate to curtail the number of parts with higher connection workability. Moreover, a heat collection plate 4 of higher heat conductivity is arranged on the heat collection part 2a and an element part of the thermistor 3 thereby improving heat response remarkably with higher heat collecting effect.

The temperature detector disclosed in the above publication can collect the temperature (heat) of the object to be heated from a wide range by means of the metal lid, but the temperature detection uses only a small temperature detecting element. While depending on the heat sensitive part,
Since the heat-resistant insulating plate is interposed between the metal lid and the thermistor, the thermal response cannot be said to be very good. In addition, in the case of this temperature detector,
As is clear from the drawings (FIGS. 1 and 2) of Japanese Patent Laid-Open No. 9-90, in addition to the above-mentioned parts, the spring receiving member (3
1), spring (4), storage case (1), etc. are required, and the number of parts is large and the structure is complicated.
The detector itself was large. The complicated structure and the increase in size of the detector not only cause the heat capacity to be large and reduce the thermal response, but also cause the problem that the assembly work is complicated and the cost is increased. .

Here, the temperature detector having the above-mentioned structure is used, in which a temperature of 100 mm is precisely adjusted from room temperature of 25 ° C. to 100 ° C.
It was pressed against the surface of an aluminum plate having a width of 150 mm and a height of 50 mm, and 63.2% response time and 90% response time were measured.

As a result, both the temperature detector of this embodiment and the temperature detector of the comparative example showed a difference of 63.2% response time of about 2.3 seconds, but a 90% response time was almost the same. In the example, it was only about 7.4 seconds, whereas in the comparative example, about 18.6 seconds, a difference of about 2.5 times was recognized. According to this, it is considered that the temperature detector of the comparative example is inferior in thermal responsiveness because good heat collection is not performed because the part that contacts the heat collecting plate is only the thermistor element part. On the other hand, in the case of the temperature detector according to the present embodiment, since the heat collecting plate is arranged in close contact with the thermistor lead wire and the electrode terminal connected to the thermistor lead wire, the heat collecting effect is enhanced and the thermal response is improved. It seems that it has improved remarkably.

1. A holding body made of a heat-resistant insulating resin is obtained by connecting a lead wire of a thermistor to a heat collecting portion of a pair of electrode terminals having a heat collecting portion and a connecting portion of a lead wire for power supply. And a heat collecting plate made of an electrically insulative molded product having high thermal conductivity is disposed in close contact with the heat collecting part of the electrode terminal and the thermistor element part of the thermistor. Temperature detector.
