Summary of the invention
Problem to be solved in the utility model is just to provide a kind of middle part outgoing line device, with the non-uniform electric field produced in the middle part of shielded coil.
For solving the problem, the utility model adopts following technical scheme:
A kind of middle part outgoing line device, comprise and connect soft shading ring successively, first square ring, second square ring and the 3rd square ring, described soft shading ring comprises external insulation ring, becket and interior dead ring, described external insulation ring to cover on becket and makes becket be clamped between external insulation ring and interior dead ring, described interior dead ring is reeled by some laminated paper boards and forms the disjunct cylinder ring of head and the tail, the first corrugated board is clamped with between described first square ring and the second square ring, the second corrugated board is clamped with between described second square ring and the 3rd square ring, described first corrugated board is mutually concordant with the second corrugated board, and the two is corresponding with interior dead ring end respectively.
In the utility model, soft shading ring is enclosed within thiol, soft shading ring comprises external insulation ring, becket and interior dead ring, wherein, external insulation ring covers on becket for avoiding becket directly to contact with coil, becket is used for the non-uniform electric field produced in the middle part of shielded coil, and becket is clamped between interior dead ring and external insulation ring, with avoid becket mutually internally dead ring occurrence positions move; Interior dead ring is reeled by some laminated paper boards and forms the disjunct cylinder ring of head and the tail, thus, is injected by fluid in the cylinder ring do not connected from beginning to end, effectively reduces the temperature of thiol.
In the utility model, the first square ring, the second square ring and the 3rd square ring are for increasing the hardness of soft shading ring, and the first corrugated board and the second corrugated board for finely tuning the diameter of soft shading ring, thus realize soft shading ring and are more adjacent to coil.In addition, inject fluid in the first corrugated board and the second corrugated board, the temperature of coil can be reduced further, thus reduce the useful life of coil.
Further, the sidewall of the contiguous head end of described interior dead ring is provided with the first opening.Design like this, the resistance to deformation power of dead ring head end in reducing, to reduce the difficulty changing soft shading ring diameter, in addition, in fluid injects by the first opening in dead ring.
Further, the sidewall of the contiguous tail end of described interior dead ring is provided with the second opening.Design like this, the resistance to deformation power of dead ring tail end in reducing, to reduce the difficulty changing soft shading ring diameter, in addition, in fluid injects by the second opening in dead ring.
Further, described middle part outgoing line device also comprises locking member, and described interior dead ring is provided with cushion block, and becket is fixed on cushion block by described locking member.When soft shading ring completes its diameter dimension of adjustment, becket is fixed on cushion block by locking member, is close to coil causes becket generation fold to avoid soft shading ring.
Further, described locking member is insulated screw.
Accompanying drawing explanation
Fig. 1 is the structural representation of middle part outgoing line device in the utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Embodiment
See figures.1.and.2, a kind of middle part outgoing line device, comprise soft shading ring 1, first square ring 2, second square ring 3 and the 3rd square ring 4, soft shading ring 1 comprises interior dead ring 11, becket 12 and external insulation ring 13, interior dead ring 11 is reeled by some laminated paper boards and forms the disjunct cylinder ring of head and the tail, external insulation ring 13 to cover on becket 12 and makes becket 12 be clamped between external insulation ring 13 and interior dead ring 11, the first corrugated board 5 is clamped with between first square ring 2 and the second square ring 3, the second corrugated board 6 is clamped with between second square ring 3 and the 3rd square ring 4, first corrugated board 5 is mutually concordant with the second corrugated board 6, and the two is corresponding with interior dead ring 11 respectively.
See figures.1.and.2, in the present embodiment, the step that thiol is fixed on the outgoing line device of middle part comprises: the first step, and thiol is through the breach interior dead ring 11 head end and interior dead ring 11 tail end; Second step, the head end of interior dead ring 11 and the tail end of interior dead ring 11 close to each other, until the 3rd square ring 4 is adjacent to coil; 3rd step, is connected as a single entity after being pasted between the head end of interior dead ring 11 and the tail end of interior dead ring 11 by glue.
With reference to Fig. 2, after the head end of interior dead ring 11 and the tail end of interior dead ring 11 are connected as a single entity, if the 3rd square ring 4 cannot be adjacent to coil, then the head end of interior dead ring 11 and the tail end of interior dead ring 11 continue close to each other, now, will there is deformation in the first corrugated board 6 and/or the second corrugated board 7, to make the reduced of interior dead ring 11, thus realize the 3rd square ring 4 and be adjacent to coil.If the 3rd square ring 4 is adjacent to coil, but the head end of interior dead ring 11 cannot be connected with the tail end of interior dead ring 11, then change the interior dead ring 11 of different-diameter.
