Abstract
An exposed portion of superconducting filaments is disposed between a sleeve end and an end portion of a stabilizer in which the stabilizer is removed from superconducting wires. The sleeve pressed together with the superconducting filaments, the exposed portion and a peripheral portion of the stabilizer next to this exposed portion are integrated with each other by a wound tensile binding material such as a copper foil and a fixing material such as solder. In accordance with such a structure, it is possible to provide a connecting method of the superconducting wires in which no superconducting filaments in a wire connecting portion are disconnected and excessively distorted and a suitable rigidity of the connecting portion is obtained.

A connecting method of superconducting wires in which a stabilizer is removed from a connecting portion of each of the superconducting wires to be connected and each of superconducting filaments exposed by this stabilizer is bundled and inserted into a sleeve and is pressed;
- said connecting method comprising the steps of:
- disposing an exposed portion of the superconducting filaments between an end portion of said stabilizer and said sleeve;
- winding said exposed portion and a peripheral portion of said stabilizer next to said exposed portion by a tensile winding material in a winding direction with a predetermined clearance;
- and
- integrating at least a portion of said sleeve, the exposed portion, the peripheral portion and said winding material with each other by a fixing material.
A connecting structure of superconducting wires comprising:
- superconducting filaments exposed from a stabilizer of each of the superconducting wires to be connected;
- a sleeve for inserting these superconducting filaments thereinto and pressed in a position separated by a predetermined length from an end portion of said stabilizer;
- a tensile binding material wound around an exposed portion of said superconducting filaments formed between an end of the sleeve and the end portion of said stabilizer and a peripheral portion of said stabilizer next to said exposed portion in a winding direction with a predetermined clearance;
- and
- a fixing material for integrating at least a portion of said sleeve, the exposed portion and the peripheral portion together with this tensile binding material.
A connecting structure of superconducting wires comprising:
- superconducting filaments exposed from a stabilizer of each of the superconducting wires to be connected;
- a conductive film attached to these superconducting filaments;
- a tensile binding material wound around a connecting portion formed by bundling said superconducting filaments and a peripheral portion of said stabilizer next to said connecting portion in a winding direction with a predetermined clearance;
- and
- a fixing material for integrating said tensile binding material, the connecting portion and the peripheral portion together with said conductive film.
