A structure is known in which lead wires 3 and 4 electrically connected to electrodes 101 and 102, respectively, are led out from the rear end surface of elastic thermally conductive coating 2. In order to insert this positive temperature coefficient thermistor device into an object such as a heated body or a heat source, a mounting hole 51 is provided in the object 5 in advance as shown in FIG.

ら押出されてしまうこともあつた。Disadvantages of the Prior Art However, in the conventional PTC thermistor device described above, when trying to increase the degree of thermal coupling to the object 5 , as shown in FIG. Since the outer diameter D 1 is made large and the elasticity of the outer diameter D 1 is made to be used to press the parts in close contact with each other, there is no place for the air inside the mounting hole 51 to escape, and the air is compressed inside the mounting hole 51 . For this reason, it sometimes became impossible to push the positive temperature coefficient thermistor device 6 into place. Furthermore, even if the PTC thermistor device 6 is pushed into a predetermined position, the air compressed in the mounting hole 51 expands due to the heat generation operation of the PTC thermistor device 6, and the expansion force at that time causes the PTC thermistor to In some cases, the device 6 was pushed out from within the mounting hole 51.

The degree of thermal coupling between the two is reduced, and thermal conductivity is impaired.

問題を生じることもない。Embodiment FIG. 6 is a plan view of a positive temperature coefficient thermistor according to the present invention, and FIG. 7 is a side sectional view of the same. In the figures, the same reference numerals as in FIGS. 1 to 5 indicate the same components. In this embodiment, in the present invention, a distal end surface 2, which is the insertion end, is attached to the outer peripheral surface of the elastic heat conductive coating 2 made of silicone rubber or the like.
It has a structure in which a concave groove-shaped communication path 7 is provided which communicates from the positive temperature coefficient thermistor 1 to the rear end surface 22 which is the lead wire extraction end surface of the positive temperature coefficient thermistor 1. With such a communication path 7, when inserting the PTC thermistor 6 into the mounting hole 51 provided in the object 5, as shown in FIG . When the outer diameter D 1 of the elastic heat conductive coating 2 is increased and the elasticity is used to make a close contact with the outer diameter D 1 of the elastic heat conductive coating 2, the air inside the mounting hole 51 will flow through the communication path 7 to the outside, as shown by arrow A. It is discharged into the air and is not compressed. Therefore, the PTC thermistor device 6 can be closely inserted into the mounting hole 51 of the object 5 without being affected by the compressive repulsion of air, and the degree of thermal coupling and thermal conductivity can be improved. Moreover, even if the air in the mounting hole 51 is heated due to the heat generation operation of the PTC thermistor device 6, it is discharged to the outside through the communication path 7, so the PTC thermistor device 6
There is no problem such as being pushed out to the outside by the heating expansion force.
