A superconducting lead comprises a supporting board (1) with at least one
superconducting tape (3) adhered to it and extending from one terminal area of
the lead
to another. Respective metal end-fittings soldered to the superconducting tape
(3) at each
of its ends, and in each of the terminal areas at least one metal insert is
bonded to the
board (1) and also soldered to the corresponding one of the said end-fittings,
so relieving
the tapes (3) of mechanical stress. The board (1), or each of them, is
preferably flat and
may support two or more superconducting tapes (3) coplanar with one another on
one or
on each of its major faces. The metal inserts are preferably of copper and may
be made
by removing most of the copper cladding from a commercially available circuit
board (1).
L'invention porte sur un fil de connexion supraconducteur qui comprend une carte support (1) à laquelle est fixé au moins un ruban supraconducteur (3) s'étendant d'une zone d'extrémité du fil à une autre. Des raccords d'extrémité métalliques respectifs sont soudés à chaque extrémité du ruban supraconducteur (3) et, à chaque zone d'extrémité, au moins une pièce métallique est fixée à la carte (1) et soudée également au raccord d'extrémité qui lui correspond pour libérer les rubans (3) de la contrainte mécanique. La carte (1), ou chaque carte, est de préférence plate et peut recevoir deux ou plusieurs rubans supraconducteurs (3) coplanaires l'un avec l'autre, sur une ou chacune de ses principales faces. de préférence, De préférence, les pièces métalliques sont en cuivre et peuvent être fabriquées par élimination de la majeure partie du surfaçage en cuivre d'une carte à circuits imprimés (1) disponible dans le commerce.
