TERMINAL STRUCTURE AND TERMINAL MEMBER OF SUPERCONDUCTING CABLE CONDUCTOR

摘要

Disclosed are a terminal structure and a terminal member for a superconducting cable conductor, wherein the mechanical strength is increased and electric connection resistance is decreased in the connecting part between the superconducting cable conductor and the terminal member. In the structure connecting a terminal part (10) of a superconducting cable conductor with a metal sleeve (30) which also serves as a terminal member for a good conductor, the terminal part (10) is provided with a superconducting layer (12) arranged on the outer periphery of a center supporting body (11) and an insulating body layer (13) surrounding the superconducting layer, wherein the insulating layer (13) and the superconducting layer (12) are stripped such that the center supporting body (11) and the superconducting layer (12) are exposed in order from the end part. The metal sleeve (30) is provided with a first cylinder part (31) the inner surface (3a) of which comes into close contact with the exposed part of the center supporting body (11), a second cylinder part (32) the inner surface (3b) of which is soldered to the exposed part of the superconducting layer (12), and a third cylinder part (33) into the inside of which is inserted the insulating body layer (13).
