METHOD OF MAKING CONNECTION OF HIGH-TEMPERATURE SUPERCONDUCTING CABLES Russian patent published in 2024 - IPC H01B12/12 

FIELD: superconducting cables.

SUBSTANCE: invention relates to high-temperature superconducting (HTSC) cables, namely to making a connection for tubular superconducting cables with flow cooling, designed to create pulsed magnetic fields. Cable strips are laid in flat terminal. Terminal is a substrate with a recess for a cable and holes for solder pouring and a cover with a bend. Cable strips are laid on a substrate pre-tinned with a solder with a melting point of at least 180 °C, in one layer. Then the prepared part of the cable is laid in the recess on the substrate, the tapes are coated with flux and pressed with a cover with a bend. Terminal is sealed along the perimeter with a high-temperature sealant, and then, through the holes in the substrate, the cable tape is poured with a solder with a melting point of at least 180 °C. After cooling of said solder to crystallization temperature, two identical terminals are connected together on the side of substrates by soldering. When soldering, a low-temperature solder with a melting point of not higher than 110 °C.

EFFECT: invention makes it possible to create a low-resistance connecting link for products.
