Abstract
The invention discloses a flexible joint of a double-C-shaped detachable magnet coil for realizing irregular arrangement of conductors, which comprises inner conductors of the magnet coil, a stainless steel shell, a solid insulating structure, a bolt fixing and assembling mechanism and a flexible assembly. According to the invention, the connected conductors which are arranged irregularly in a certain range can extend freely in a condition of meeting the insulating performance and the connecting strength of bodies, an enough flexible contact space is ensured to resist affect of electromagnetic force on the electrified conductors. Meanwhile, excellent contact electrifying performance of the connected conductors is met. Special design of the flexible assembly can avoid the condition that when the inner conductors of the magnet coil operates and is under large electromagnetic force, the conductors at both ends of the joint are affected by the lorentz force and shift towards opposite directions to cause poor contact. The material of the flexible assembly effectively reduces the resistance of the joint and a solidified and formed insulating plate consisting of compound material power or fiber (polyimide plus a glass tape) and epoxy resin has effective insulating effect to high-current conductors.
