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.

Summary of the invention
The objective of the invention is to propose a kind of flexible joint that realizes the two detachable magnet coils of C of conductor irregular alignment; Can be under the situation that satisfies body insulation property and bonding strength; Realize being connected irregular alignment conductor freely stretching within the specific limits; Assurance also has enough flexible attaching spaces to resist the influence of electromagnetic force to electrical conductor, satisfies simultaneously the performance of being switched on by the good contact of bonding conductor.
Technical scheme of the present invention is following:
Realize the flexible joint of the two detachable magnet coils of C of conductor irregular alignment; Include the inner conductor of magnet coil; It is characterized in that: include Stainless Steel Shell, solid insulation structure, bolt assemble mechanism and flexible unit; The left and right two ends of described Stainless Steel Shell are not sealed, and Stainless Steel Shell inside is filled with the solid insulation structure, and the solid insulation structure is processed with the corresponding through hole of concrete arrangement mode of inner conductor of a plurality of and magnet coil as the conductor jack; Described flexible unit includes spring, sheffield plate; Sheffield plate along spring shaft to fixed overlay and the intensive entire inner space that is full of spring; The external diameter of sheffield plate and spring inside diameter are interference fit; The external diameter of flexible unit and conductor jack adopt interference fits, and flexible unit is assembled to the axial centre position of solid insulation inside configuration conductor jack; Described bolt assemble mechanism includes the left and right two ends that one, four L template one of four L templates is separately fixed at the upper and lower end face of Stainless Steel Shell, has a plurality of screwed holes on the vertical panel of described L template one.
The cross section at the left and right two ends of described Stainless Steel Shell is identical with the cross section of magnet coil shell; The magnet coil shell is provided with fixedly assemble mechanism of magnet coil shell; Magnet coil shell fixedly assemble mechanism includes on the upper and lower end face at four left and right two ends that are installed on the magnet coil shell respectively the L template one L template two corresponding and that be used in twos with it on the upper and lower end face with the left and right two ends of Stainless Steel Shell, and the described L template that is used in twos, two is installed and through passing the bolt of screwed hole back-to-back.
Described solid insulation structure adds epoxy resin curing molding in Stainless Steel Shell by composite material powder or fiber (polyimides+glass tape); After moulding, according to the concrete arrangement mode of the inner conductor of magnet coil, machining goes out the conductor jack.
After the two ends that the two ends of the inner conductor of described magnet coil are passed conductor jack and flexible unit respectively tightly propped up, the L template one, two that will be used in twos again was through passing the bolt of screwed hole.
Flexible unit mainly with sheffield plate along spring shaft to fixed overlay; And the intensive whole spring inner space that is full of, sheffield plate external diameter and spring inside diameter are interference fit, according to Hooke's law (△ F=k Δ x); Lorentz force when the stiffness factor k of spring must move according to magnet coil is checked setting in detail; To guarantee enough mechanical flexibility shock-absorbing capacities, make under big electromagnetic force operating mode, the conductor at joint two ends do not receive Lorentz force to influence round about displacement causes loose contact; Flexible unit mainly plays the effect of conductor, make the conductor at two ends under receiving the situation of any external interference all with flexible unit in both ends of the spring contact well.
Beneficial effect of the present invention is:
The present invention can be under the situation that satisfies body insulation property and bonding strength; Realize being connected irregular alignment conductor freely stretching within the specific limits; Assurance also has enough flexible attaching spaces to resist the influence of electromagnetic force to electrical conductor, satisfies simultaneously the performance of being switched on by the good contact of bonding conductor.
