Superconducting magnet wire terminal device and method for realizing connection

Abstract

The invention discloses a superconducting magnet wire end socket device and a connection implementation method of a superconducting magnet wire. The superconducting magnet wire end socket device includes a base, a pressing piece, a non-magnetic spring and a metal welding platform. The base is used for fixing the pressing piece and the metal welding platform. The pressing piece has a radian, the tail end of the pressing piece is located at a high position, and the pressing piece is placed behind a wire inlet guiding device of a wire inlet end. The non-magnetic spring is used for achieving elasticity stroke control to the pressing piece. The metal welding platform is fixedly arranged at the wire outlet end of a base plate of the base, the front end part of the metal welding platform is placed below the tail end part of the pressing piece, and the front end part of the metal welding platform and the tail end part of the pressing piece are adjacent to each other and have mutually-matched curvature. The height fall between a wire inlet port of the base and the metal welding platform exists, and the elasticity pressing piece is placed between the horizontal position of the wire inlet port of the base and the horizontal position of the metal welding platform. The method comprises the following steps: a pair of end socket devices is pre-manufactured, wherein the two end socket devices are symmetrical in structure; superconducting strips in two to-be-connected magnet coils respectively enter from the wire inlet ports of bases of the two end socket devices, pass through the pressing piece and then are respectively attached to the metal welding platform in a paving mode to be welded and fixed; and butt joint and firm welding are achieved.

AI Technical Summary

Problems solved by technology

For a superconducting magnet, the lead-out end of the wire in the superconducting magnet coil is the weakest part of the magnet. Local internal stress concentration occurs in the part, which will cause damage to the lead wire of the superconducting coil or breakage of the welding end in severe cases
