Abstract
A joint structure of a superconducting cable having improved connection strength and preventing break of a superconducting layer is provided. A central conductor of an insulating spacer and a superconducting cable are connected via a conductor connecting member having a sleeve-shaped end. Specifically, the central conductor of the insulating spacer and the conductor connecting member are connected by multi-contact connection.
Claims20
A joint and cable structure comprising:
- a superconducting cable;
- a long conductor;
- a conductor connecting member connecting said superconducting cable and said long conductor;
- and
- an insulating spacer covering said conductor connecting member, wherein
- a connecting portion of said conductor connecting member and said superconducting cable is arranged inside a hollow tube that is provided at a core portion of said insulating spacer;
- and
- wherein said insulating spacer covers a region extending at least from a connected portion of said superconducting cable and said conductor connecting member to a connected portion of said long conductor and said conductor connecting member.
A joint structure for coupling a superconducting cable and a further cable together, the joint structure comprising:
- a conductor connecting member for connecting a superconducting cable and a further conductor;
- and
- an insulating spacer covering at least a portion of the conductor connecting member, the insulating spacer including a core portion and a hollow tube located at least partially in the core portion;
- wherein the conductor connecting member has a pair of connecting portions disposed within the hollow tube for connecting to the superconducting cable and the further cable, respectively;
- and
- wherein the insulating spacer covers a portion of the conductor member that extends at least from the connecting portion of the conductor connecting member and the superconducting cable to the connecting portion of the conductor connecting member and the further cable.
