The invention relates to a coil for producing a magnetic field having at least one winding (12), which is manufactured from a superconductor, is cast into a plastic and whose winding end (19) which is arranged at the circumference (13) of the winding (12) is used for making contact with an electrical conductor (15). In order to provide coils with windings (12) consisting of superconductors which make robust contact-making possible given simple production, an electrically conductive connection piece (30) with a base region (31), which is connected to the winding end (19), and a top region (32) for connecting the conductor (15) is provided for contact-making purposes, the base region (31) of said connection piece (30) being covered partially in the radial direction by a reinforcing insert (14), which is cast into the plastic (20) and at least partially surrounds the winding (12).
A coil for producing a magnetic field, having at least one winding which is manufactured from superposed turns of a superconductor and is encapsulated in a plastic, with a winding end which is arranged on the circumference of the winding being used as a contact for an electrical conductor, the contact having an electrically conductive connecting piece with a foot area, which is connected over an area to the winding end, and with a head area for connection of the conductor, with the foot area of the connecting piece including limbs which rest directly on the winding end and which are at least partially covered in the radial direction by a reinforcing insert which is encapsulated in the plastic and at least partially surrounds the winding, wherein the connecting piece has a recess in the form of a groove on both side faces of the connecting piece, the reinforcing insert engaging the groove.
A coil for producing a magnetic field, having at least one winding which is manufactured from superposed turns of a superconductor and is encapsulated in a plastic, with a winding end which is arranged on the circumference of the winding being used as a contact for an electrical conductor, the contact having an electrically conductive connecting piece with a foot area, which is connected over an area to the winding end, and with a head area for connection of the conductor, with the foot area of the connecting piece including limbs which rest directly on the winding end and which are at least partially covered in the radial direction by a reinforcing insert which is encapsulated in the plastic and at least partially surrounds the winding, wherein the limbs project beyond the head area in the circumferential direction.
