A cryostat is provided for housing for a superconducting wired circuit. The cryostat has a dividing partition () delimiting two internal spaces; a first and a second opening situated one on each side of the dividing partition and each configured to fix one end of a cryogenic jacket surrounding at least one superconducting wire () and to allow the superconducting wire to pass into the internal spaces. A third outlet opening is provided for a cooling fluid circulating in the cryogenic jacket fixed to the first opening. A fourth inlet opening is for a cooling fluid circulating in the cryogenic jacket fixed to the second opening. The dividing partition () incorporates a cavity forming a partition feedthrough (T) allowing the superconducting wire to pass through and sealed against the cooling fluids by the injection, once the wire has been fed through, of an electrically insulating material () in polymerizable liquid form, via an access opening () providing access to said cavity.

An electrically connecting device () includes a linking part defining an internal channel () that opens onto the exterior of the linking part. The internal channel () is able to receive two end segments of two superconducting wires () that lie parallel in the internal channel () over a segment of common length; and an aperture () in the external jacket of the linking part. The aperture () is in communication with the internal channel () in order to allow a brazing material in liquid form to be inserted into the internal channel () around the two end segments of the two superconducting wires ().
