Abstract: The present application relates to a current lead structure and a superconducting magnet. The current lead structure comprises a fixed connector, a movable connector, and a deformable sealing assembly establishing a sealed connection between the movable connector and a housing of the superconducting magnet. An external force elastically deforms the deformable sealing assembly, and under the action of a force from the deformation, the movable connector moves, with respect to the housing of the superconducting magnet, in a reciprocating manner between a connection position enabling contact with the fixed connector and a disconnection position away from the fixed connector. In the current lead structure and the superconducting magnet provided in the present application, the movable connector moves to connect to the fixed connector during excitation or a field strength decrease, thereby conducting superconducting coils with an external loop. After the superconducting coils form a closed loop, the movable connector moves to disconnect from the fixed connector while still being connected to the housing of the superconducting magnet via the deformable sealing assembly. In this way, the current lead structure has the operational convenience of permanent current leads, and the advantage of temporary current leads in which unplugging does not cause additional thermal conduction.
