Title: CONNECTION STRUCTURE BODY FOR OXIDE SUPERCONDUCTING WIRE MATERIAL AND METHOD FOR MANUFACTURING SAME
Abstract:
A connection structure body for oxide superconducting wire material comprises: a pair of oxide superconducting wire materials each having a first oxide superconducting layer and a first stabilization layer which are successively laminated on a tape-shaped first base material, the oxide superconducting wire materials being disposed with tip-end surfaces thereof opposing each other; a first-surface connecting superconducting wire material including a second oxide superconducting layer and a second stabilization layer which are successively laminated on a tape-shaped second base material, and trunk-connecting the pair of oxide superconducting wire materials; and a second-surface trunk-connecting body trunk-connecting the pair of oxide superconducting wire materials. The first-surface connecting superconducting wire material is bonded to the pair of oxide superconducting wire materials so that the second stabilization layer opposes the first stabilization layer of the pair of oxide superconducting wire materials. The second-surface trunk-connecting body is bonded to the pair of oxide superconducting wire materials so as to oppose the first base material of the pair of oxide superconducting wire materials. A tensile strength at a bonding portion of the second-surface trunk-connecting body and the pair of oxide superconducting wire materials is higher than a tensile strength at a bonding portion of the first-surface connecting superconducting wire material and the pair of oxide superconducting wire materials.
