箇所である。 This compensation conductor 2 is used for boilers, turbines, generators,
It is used as a lead wire for thermocouple 1 and temperature indicator 11 when electrically measuring the temperature of electric furnaces, LPG tanks, etc., and its usage is shown in Figure 4. What is shown in FIGS. 1 to 3 is a portion indicated by A of the connection portion between the thermocouple 1 and the compensation conducting wire 2 shown in FIG. 4.

のである。 The conventional method for connecting thermocouples and compensation wires (mainly stranded wires) is the silver brazing method, which uses silver solder 3 to connect thermocouple wire 1 and compensation wire 2 by brazing, as shown in Figure 1. As shown in Fig. 2, a caulking method has been implemented in which the thermocouple wire 1 and the compensating conductor wire 2 are connected using a pipe 4 by caulking the pipe 4, but none of these conventional methods Since dissimilar metals are used for the parts, if a temperature gradient occurs at the connected part, a thermoelectromotive force will occur in this part, causing an error and interfering with temperature measurement.
本発明は、叙述の欠点を除き正確な温度測定を
得るため、従来の異種金属を用いて接続していた
ものを、異種金属を使用せずに、熱電対線と補償
導線とを接続する両線を同体として接続するもの
である。 In order to eliminate the drawbacks mentioned above and obtain accurate temperature measurements, the present invention provides a method for connecting thermocouple wires and compensating conductors without using dissimilar metals, instead of the conventional connection using dissimilar metals. It connects wires as one body.
即ち、撚線でなる補償導線２の先端の被覆を除

より溶着し同体にして接続するものである。 In other words, the tip of the compensating conductor 2 made of strands has its coating removed, the tip is melted and made into a single piece, and both sides of the tip are made flat, and the tip of the wire of the sheathed thermocouple 1 is made flat on both sides. The two are welded together by spot welding or the like and connected as one unit.
