Title:
CONNECTOR FOR SUPERCONDUCTING WIRE AND METHOD FOR CONNECTING SUPERCONDUCTING WIRE
Document Type and Number:
WIPO Patent Application WO/2022/050000
Kind Code:
A1
Abstract:
The present invention provides a connector for a superconducting wire and a method for connecting a superconducting wire in which a plurality of superconducting wires are integrated by a sintered compact that contains MgB2, and for which high energization characteristics can be obtained. In the connector for a superconducting wire, a plurality of superconducting wires (1) are integrated by a sintered compact (9) that contains MgB2. The superconducting wires (1) have end parts in which the outer peripheral surface of superconducting filaments (12) are exposed inserted in a container (5) in parallel to each other. The container (5) is of such construction as to have an opening part (5a) that is larger than the diameter of the superconducting wires (1) on at least one lengthwise-direction side of the inserted superconducting wires (1). The sintered body (9) is in contact with the outer peripheral surface of the superconducting filaments (12). The method for connecting a superconducting wire includes: a step for exposing the outer peripheral surface of the superconducting filaments (12); a step for inserting the superconducting wires (1) into the container (5); a step for filling the container (5) with a raw material; and a step for creating the sintered body (9) by heat treating the raw material. The raw material is pressurized in parallel to the lengthwise direction of the superconducting wires (1) and then heat treated.
