TERMINAL STRUCTURE OF SUPERCONDUCTING CABLE

PROBLEM TO BE SOLVED: To provide a terminal structure of a superconducting cable with which the superconducting cable and a terminal metal fitting can be electrically connected to each other suitably and surely and they are structurally compactly and firmly connected to each other.SOLUTION: There are provided a superconducting cable 110 having plural superconducting tapes 113, 115 arranged at the outside of a core material 111 to surround the core material 111 concentrically and a cylindrical electrode 120-1. The superconducting cable 110 is passed through the cylindrical electrode 120-1, and the superconducting tape 115 is electrically connected to the outer surface of the cylindrical electrode 120-1. A coating member 160 is provided between the superconducting cable 110 and the cylindrical electrode 120-1, and covers the periphery of the superconducting cable 110 in the cylindrical electrode 120-1. A fastening member 140 is provided to project from the inner surface of the cylindrical electrode 120-1, and presses the coating member 160 to fasten the superconducting cable 110 to the cylindrical electrode 120-1. 【課題】超電導ケーブルと端末金具とを電気的に好適に確実に接続するとともに、双方を、構造的にコンパクトで強固に接続すること。【解決手段】芯材１１１の外側に、同心円状に巻き付けて配置された複数の超電導テープ１１３，１１５を有する超電導ケーブル１１０と、筒状電極１２０−１とを有する。超電導ケーブル１１０は、筒状電極１２０−１の内部に通されるとともに、超電導テープ１１５が、筒状電極１２０−１の外面に電気的に接続されている。被覆部材１６０は、超電導ケーブル１１０と筒状電極１２０−１との間に設けられ、且つ、筒状電極１２０−１内で超電導ケーブル１１０の周囲を覆う。止着部材１４０は、筒状電極１２０−１の内面から突出して設けられ、被覆部材１６０を押圧して超電導ケーブル１１０を筒状電極１２０−１に止着する。【選択図】図４
