STORAGE BOX OF COMPENSATION LEAD WIRE FOR THERMOCOUPLE

PROBLEM TO BE SOLVED: To provide a storage box of compensation lead wires for a thermocouple, which can prevent melting of vinyl sheaths.SOLUTION: In the storage box 10, a plurality of first compensation lead wires 1 connected to a thermocouple having a temperature sensitive part and coated with a metal sheath 1a are approximately bound and led into the storage box 10, and a plurality of compensation lead wires 2 respectively connected to the first compensation lead wires 1 and respectively coated with vinyl sheaths 2a are led out from the storage box 10. The storage box 10 includes a wiring bar 4 arranged in an approximately horizontal state in its inside. The plurality of vinyl sheaths 2a are moored at the wiring bar 4 so that the metal sheaths 1a and the vinyl sheaths 2a are separated from each other. The storage box 10 can avoid contact between the metal sheaths 1a and the vinyl sheaths 2a and prevent melting of the vinyl sheaths 2a.
