PURPOSE:To prevent induction of quench due to vibration of a superconductive lead or others in a superconductive electromagnet by a method wherein a connection member composed of copper mateials or the like is fixed in a leadout port and also is fixedly connected to a power lead conductor and the superconductive wire by soldering or other proper work. CONSTITUTION:A power-leads leadout port 4 to feed the power externally is formed in an inner chamber 1 accommodating a superconductive coil 7. The port consists of a housing 4B and a power-leads through guide 4A. Power lead 5 is composed of a conductor 5A and a pipe 5B. Pipe 5B is seal-fixed to the through guide 4A, and conductor 5A is held in conduction by a connection member 14 via an insulator 15 and connected to a connection member 11A which is composed of copper materials and fixed with insulators 12A and 12B. The far end of the connecting member 11A combines a superconductive wire 10 with a supporter 11B of a curved tongue shape and is securely fixed with the power-lead conductor 5A via the connection member 11A by means of soldering or the like. |
