Abstract

Abstract A method of connecting superconducting wires have the steps of preparing a connecting superconducting wire piece, exposing the filaments of the superconducting layers to be connected and the filaments of the connecting superconducting wire piece by partially dissolving and removing the coating layers, inserting the filaments of the superconducting wires to be connected into the filaments of the connecting superconducting wire piece such that the filaments of the connecting superconducting wire piece cross and envelope the filaments of the superconducting wires to be connected, fitting a metallic connecting pipe on the region where the filaments cross each other, and crimping the metallic connecting pipe onto the crossing filaments thereby tightly fixing and connecting the exposed filaments to each other.
