Abstract
A termination structure of a cryogenic cable has a cryogenic-cable end portion and a current-lead end portion that are coupled to each other with a flexible conductor. Accordingly, any displacement in three-dimensional directions of the end portions that could occur due to thermal expansion and thermal contraction of the cryogenic cable and the current lead can be absorbed, and a sufficient current capacity can be ensured.
Claims15
A termination structure of a cryogenic cable comprising:
- a cryogenic-cable end portion;
- a current-lead end portion;
- and
- a flexible conductor having a first end connected to said cryogenic-cable end portion and a second end connected to said current-lead end portion, said flexible conductor bent in a “U”-shape such that the first and second ends of the flexible conductor are oriented in the same direction as a longitudinal direction of said cryogenic-cable end portion.
A termination structure of a cryogenic cable comprising:
- a cryogenic-cable end portion;
- a current-lead end portion;
- and
- a flexible conductor connecting said cryogenic-cable end portion and said current-lead end portion to each other, wherein
- said current-lead end portion has a conductive terminal, said conductive terminal has a hollowed part, said hollowed part or an outer periphery of a lower part of said current-lead end portion have a predetermined number of grooves, and, with an electrically-conductive elastic body inserted into said grooves, said current-lead end portion is inserted into said hollowed part.
