Abstract

The disclosed connector can be used to connect superconductive conductors. The connector, which is suitable for electrically connecting at least one first superconductive conductor to at least one second superconductive conductor, includes an electrically conductive base element having a first end portion and a second end portion, and at least one superconductive additional element arranged in the base element extending from the first end portion to the second end portion of the base element.

First claim

The invention claimed is:

1. A connector for electrically connecting at least one first superconductive conductor to at least one second superconductive conductor, the connector comprising:
an electrically conductive base element having a first end portion, at which the at least one first superconductive conductor is electrically contactable, and a second end portion, at which the at least one second superconductive conductor is electrically contactable; and
at least one superconductive additional element arranged in the base element, at least in part, and extending from the first end portion to the second end portion of the base element.

2. The connector according to claim 1 , wherein the base element has at least one recess or groove, in which the at least one superconductive additional element is arranged, at least in part, and/or wherein the at least one superconductive additional element is electrically in contact with the base element.

3. The connector according to claim 1 , wherein the base element comprises a plurality of base element parts.

4. The connector according to claim 3 , wherein a length of the at least one superconductive additional element is greater than the sum of lengths of the base element parts.

5. The connector according to claim 4 , further comprising a displacement groove, in which at least one of the base element parts is displaceable.

6. The connector according to claim 1 , wherein the base element is suitable to electrically connect n first superconductive conductors with n second superconductive conductors, wherein the connector comprises n or an integral multiple of n superconductive additional elements, and wherein n is a natural integer greater than zero.

7. The connector according to claim 1 , wherein the at least one conductive base element is formed to be rectilinear or angled.

8. A method of using the connector of claim 1 , the method comprising:
connecting at least one first superconductive conductor to at least one second superconductive conductor,
wherein the at least one first and the at least one second superconductive conductor each include a plurality of superconductor strips, which are each arranged into a strip stack and each form a superconductor body of the respective superconductive conductor.

9. The method according to claim 8 wherein the superconductor body has a cross-shaped cross-section.

10. The method according to claim 8 , wherein the strip stack of the superconductor body has superconductor strips with exactly two different widths.

11. The method according to claim 8 , wherein the first end portion of the connector is electrically contacted with the superconductor body of the at least one first superconductive conductor and/or the second end portion of the connector is electrically contacted with the superconductor body of the at least one second superconductive conductor.

12. The method according to claim 8 , wherein the first end portion of the connector is electrically contacted with a cladding tube of the at least one first superconductive conductor-and/or the second end portion of the connector is electrically contacted with a cladding tube of the at least one second superconductive conductor.

13. The method according to claim 8 , wherein the first end portion of the connector is electrically contacted with both the cladding tube and the superconductor body of the at least one first superconductive conductor.

14. The method according to claim 11 , wherein electrical contacting is performed by pressfitting or thermal joining.

15. The connector according to claim 1 , wherein the base element comprises a joint and/or wherein the base element is formed of copper partially or completely and/or wherein the at least one superconductive additional element comprises a superconductor strip or a stack of superconductor strips.

16. The connector according to claim 1 , wherein the base element is formed of copper partially or completely and/or wherein the at least one superconductive additional element comprises a superconductor strip or a stack of superconductor strips.

17. The connector according to claim 1 , wherein the at least one superconductive additional element comprises a superconductor strip or a stack of superconductor strips.

18. The connector according to claim 7 , wherein the at least one conductive base element is formed such that in an assembled state of the connector, a longitudinal axis of the at least one first superconductive conductor and a longitudinal axis of the at least one second superconductive conductor enclose an angle between 0° and 180°.

19. The method according to claim 13 , wherein the second end portion of the connector is electrically contacted with both the cladding tube and the superconductor body of the at least one second superconductive conductor.
