<p>PROBLEM TO BE SOLVED: To provide a current lead which improves reliability (mechanical characteristics, electrical characteristics) and on-site mounting workability and is capable of downsizing.SOLUTION: The current lead comprises: an element unit in which a low-temperature-side core electrode is joined to the side of a low-temperature part in a thermoelectric transducer, and a normal-temperature-side core electrode is joined to the side of a normal-temperature part in the thermoelectric transducer; a low-temperature-side cap electrode, one end side of which is connected to a superconductive application device and the other end side of which is connected to the low-temperature-side core electrode by a plug-socket structure; a normal-temperature-side cap electrode, one end side of which is connected to an external device and the other end side of which is connected to the normal-temperature-side core electrode by a plug-socket structure; and multipoint contact type contacts interposed between the low-temperature-side core electrode and the low-temperature-side cap electrode and between the normal-temperature-side core electrode and the normal-temperature-side cap electrode. The element unit is held so as to be movable axially between the low-temperature-side cap electrode and the normal-temperature-side cap electrode.</p> |
