A superconductive connecting device of at least one embodiment is used to contact the end pieces of two superconductors, each of which includes at least one conductor lead that is made of a superconductive MgB2 material and embedded in a matrix made of a normally conductive material, the conductor lead being directly sheathed with a barrier material. In a connecting region, the conductor leads of the end pieces, which are at least partially stripped of the matrix material and the barrier material, are arranged inside a sleeve or bushing, and a magnesium diboride (MgB2) material is additionally present as a superconductive contacting material which is located at least in some partial regions between the conductor leads. For establishing the connection, the cross-section of the sleeve or bushing filled in this way is reduced. |
