CURRENT LEAD

摘要

PROBLEM TO BE SOLVED: To provide a current lead excellent in reliability (mechanical characteristic, electrical characteristic) and installation workability in a site and capable of being miniaturized.SOLUTION: The current lead includes: an element unit configured by joining a low temperature side core electrode to the low temperature part side of a thermoelectric conversion element and joining a normal temperature side core electrode to the normal temperature part side of the thermoelectric conversion element; a low temperature side cap electrode of which one-end side is connected to a superconductive application apparatus and the other end side is connected to the low temperature side core electrode by a plug socket structure; and a normal temperature side cap electrode of which one-end side is connected to an external apparatus and the other end side is connected to the normal temperature side core electrode by the plug socket structure. The element unit is held so as to be moved in an axial direction by the low temperature side cap electrode and the normal temperature side cap electrode and a support post is interposed between the low temperature side cap electrode and the normal temperature side cap electrode.
