AI Technical Summary

⚠Technical Problem

Conventional methods for connecting current terminals to superconducting cables require complex equipment and processes involving heat and vacuum, leading to inconsistent and difficult-to-reproduce electrical connections.

⚗Method used

A terminal design using inner and outer sleeves with tapered portions and slots that apply uniform clamping pressure without heat or vacuum, allowing for consistent and low-resistance connections through mechanical compression.

🎯Benefits of technology

The solution provides a repeatable, low-resistance connection that maintains uniform contact resistance across the cable, reduces equipment complexity, and prevents cracking, while being easy to install in the field.

Abstract

Embodiments described herein include a contact terminal configured to be disposed around a portion of a conductive elongate member. The contact terminal may include an inner sleeve including a first end portion, a second end portion, and a central portion therebetween. The contact terminal may include a pair of outer sleeves configured to be disposed around the first end portion and the second end portion. The inner sleeve may define one or more slots and taper from the central portion to each of the first end portion and the second end portion. The inner sleeve may deform to distribute a clamping pressure to the portion of the conductive elongate member. The inner sleeve and the outer sleeve may include a conductive material such that a current can be injected or withdrawn from the conductive elongate member.
