される。A thermocouple relay connector is convenient when there is a long distance between the measuring point where temperature measurement is required and the measuring instrument for measuring the electromotive force of the thermocouple. The conventional thermal IT-pair relay connector, which serves this purpose, is similar to commonly used cable connectors in that the plug receiving metal fitting is pressed in the direction in which the radius thereof becomes smaller. Then, the contact area between the plug and the plug holder is made narrow, and both are compressed in the radial direction. The plug and plug holder are selected to be of the same type as the wire of the thermocouple, respectively, and K is selected so that the existence of the plug does not affect the electromotive force of the thermocouple.

性能の劣化がみられるだめ適宜交換の必要があったが、
従来、中間にコネクタを有しないため熱電対を全て交換
する必要があり不経済であった。However, in an atmosphere with a sieve temperature of zero degrees, such as a thermocouple connected to the outer surface of the top cover of a nuclear reactor gutter, pure copper becomes extremely oxidized, causing oxidation to occur on the surface of the connection surface of the connector. 1 wear will occur and the reliability of the connector will be lost. For this reason, connectors for thermocouples have not been used for a long time in the warm atmosphere. Since the connector cover is never used, during inspection and maintenance of the reactor, one end of the thermocouple is removed from the top cover surface, its tip is wrapped excessively, and it is placed in the space near the pressure vessel. was. As a result, one end of the thermocouple obstructs the inspection worker's passage, and there is a risk that the thermocouple may be stepped on. My father, the thermocouple was constantly exposed to high temperatures and its performance deteriorated, so it was necessary to replace it from time to time.
Conventionally, since there was no intermediate connector, it was necessary to replace all the thermocouples, which was uneconomical.
そこで、本発明は以上のような問題点を解決する耐熱用

, the elastic force of the elastic body 7 is applied to the line contact portion as =L and 17. Therefore, the pressing force per unit area at the contact portion is extremely large. At the same time, since the connecting parts 6 of the plug holders 4 and 5 have a corner shape in cross section as shown in FIG. 5, even if an oxide film exists 12 on the surface of the line contact part, the oxide film is broken. As a result, a good electrical connection is made between the plugs 1 and 2 and the plug holder 4.5. Furthermore, since the packing 18 is interposed at the joints of the base 8 and the main body case 14, the air inside and outside of them is almost airtightly cut off, and the outer peripheral surfaces of the plugs 1 and 2 and the plug holder fittings 4 and 5 are interposed. Slows down the progress of oxidation on the inner peripheral surface.

Then, a connecting portion 6 having a corner shape in cross section that is sharp enough to break the oxide film of the connecting portion 3 is formed on the inner surface of the plug receiving fittings 4 and 5. Furthermore, an elastic body 7 is attached to the plug 1.2 or the plug holder 4.5.
The plug 1.2 or the plug receiving metal fittings 4, 5 are pushed in their axial direction, and the above +8: connecting portion 6 of the thread surface 3 collides with the connecting portion 6 of the thread surface 3.

The plugs 1 and 2 are connected by the action of the connecting portion 6 having a corner-shaped cross section.
The oxide film between the connection parts of the plug holders 4 and 5 is broken and the two are pressed together, and since there is no air in the suppressed connection part, electrical continuity is maintained without oxidation in that part. It has the effect of Further, when the connecting portions between the two are worn out, a new connecting portion is formed by the plugs 1 and 2 advancing toward the distal ends 1 through the action of the elastic body 7. As a result, it is possible to provide an extremely reliable connector even in a high-temperature atmosphere with significant oxidation. According to experiments, 280
After leaving this connector in the connected state for approximately 600 hours in an atmosphere of A non-oxidized ring is formed, and only that part exhibits a copper color12
, all other parts were covered with an oxide film. This experimentally proves the existence of the ``Dii effect''.
