Title: Connection structure between oxide superconductor and normal conductor
Inventor: TAN MASAYUKI
IPC: H01R4/68
Filed: 1987-04-15
Abstract: PURPOSE:To improve durability of the connection structure in the caption by interposing a cushion layer made of a material whose coefficient of thermal expansion is closer to that of an oxide superconductor than to that of a base, between the base and the oxide superconductor. CONSTITUTION:A cushion layer 4 is made of a selected material having its coefficient of thermal expansion closer to that of oxide superconductive material used for a superconductor 3 than to that of a base 2. In order to form a connection body 1, a molding is formed at first by press-molding the material power of the superconductor 3 in a thin plate shape, then heat treatment is applied to this molding to form a thin-plate shaped superconductor 3 having superconductivity. Then, brazing process is applied between this superconductor 3 and plate- like cushion layer 4, and between the plate-like cushion layer 4 and a plate-like metallic base 2 made of copper etc. respectively. As the result of this process, the base 2, the cushion layer 4 and the superconductor 3 are piled in this order so that the connection body 1 can be formed in a disc shape in which each of them is in the state of mutual connection.
