Between 7 internal face, and make elastic deformation portion 3d elastic deformations, movable guide portion 3e is shifted to close to the direction of iron core 2.
Figure 10 is the stereogram for showing to be mounted with the state of coil group 4 on Fig. 8 iron core 2, and Figure 11 is shown in Fig. 9
The sectional view of the state of coil group 4 is mounted with iron core 2.In connection process, winding portion 4a is arranged on corresponding teeth portion 2a
After upper, by the 4b connections of end wires portion, that is, wind and be fixed on corresponding terminal pins 5.Now, end wires portion 4b is being applied with
Movable guide portion 3e is hung in the state of the tension force for meeting wire gauge.
Figure 12 is to show the stereogram from the state after Figure 10 disassembling jig 6 of stator 1, and Figure 13 is to show determining from Figure 11
The sectional view of state after sub 1 disassembling jig 6.In cuttling, pin portion 6a is extracted from coil-end connecting portion 3b, by tool
6 pull down from stator 1.Thus, elastic deformation portion 3d restores, and movable guide portion 3e (reduces by terminal to the direction for leaving iron core 2
The direction for the reaction force that wire portion 4b tension force is produced) return.
In such stator 1, make elastic deformation portion 3d elastic deformations, end wires portion 4b is connected with terminal pins 5, made
Elastic deformation portion 3d restores, and thus, it is possible to stabilization and easily forms relaxation in end wires portion 4b.
Further, since end wires portion 4b is not contacted directly with the pin portion 6a of tool 6, end wires portion 4b not with pin portion 6a
Wiping is touched, and can prevent end wires portion 4b insulating coating from damaging and breaking.
Moreover, the deflection by adjusting elastic deformation portion 3d, can be easily adjusted end wires portion 4b slack.
Also, end wires portion 4b relaxation direction more reliably turns into movable guide portion 3e lateral direction, therefore eventually
Wire portion 4b stable posture is held, end wires portion 4b broken string risk can be reduced.
Also, pin portion 6a is inserted between linking part 3f and connecting portion main body 3c, makes elastic deformation portion 3d elastic deformations, because
This thickness by changing pin portion 6a, easily movable guide portion 3e shift amount can be micro-adjusted.Thereby, it is possible to adjust
Whole end wires portion 4b slack, prevents end wires portion 4b unwinding and comes off.
In addition, the installation direction (pin portion 6a direction of insertion) of tool 6 with the winding process for coil group 4 by iron core
2 be installed on coiling machine (not shown) direction (axial direction of iron core 2) it is identical, therefore by the way that tool 6 is arranged at into coiling machine in advance,
Can implement iron core 2 to be installed on for winding process the process and elastic deformation process of coiling machine simultaneously.
In addition, Figure 14 is the explanation figure for the major part for schematically showing Figure 11.Movable guide portion 3e is with relative to subtracting
The obtuse-angulate mode of direction shape of few reaction force being subject to from the end wires portion 4b of contact tension force is shifted.Therefore, around
During line, due to end wires portion 4b tension force, end wires portion 4b produces the power of the foundation direction effect to movable guide portion 3e,
It can prevent end wires portion 4b from being come off from movable guide portion 3e.
In addition, fixed guide portion 3g is provided with coil-end connecting portion 3b, therefore, it is possible to prevent the pin portion 6a of tool 6 naked
Dew, protection end wires portion 4b.In addition it is also possible to by by end wires portion 4b is in movable guide portion 3e and fixes guide portion 3g
Relaxation is formed more reliably around one week (the extension methods different from embodiment 1) of extension in upper totality.
Embodiment 2
Then, Figure 15 is the stereogram of the part suitable with Fig. 3 for the stator for showing embodiments of the present invention 2, Figure 16
The stereogram of the part suitable with Fig. 4 for the stator for showing embodiment 2, Figure 17 be the stator of embodiment 2 with Fig. 5 phases
When part sectional view.
In embodiment 1, the elastic deformation portion 3d of L-shaped, but the bullet in embodiment 2 using U-shaped are shown
Property variant part 3h.Other structures are identical with embodiment 1.
According to such structure, compared with embodiment 1, elastic deformation portion 3h length can be extended, can be flexibly
Support movable guide portion 3e.Therefore, it is possible to expand movable guide portion 3e shift amount.
Moreover, it is not necessary to being made up of the high elastomeric element of flexibility includes elastic deformation portion 3h insulator 3, it can alleviate pair
Use the limitation of material.

Guide portion.That is, movable guide portion can also separately be shifted.
Moreover, in embodiment 1,2, on coil-end connecting portion 3b width, in adjacent movable guide portion
Elastic deformation portion 3d, 3h are configured between 3e, but non-necessity is located between movable guide portion, for example, can also make adjacent elasticity
Deform integrally.But, in order that elastic deformation is easily, the width dimensions in elastic deformation portion are preferably than the broad-ruler of linking part
It is very little small.
Also, in embodiment 1,2, it is provided with fixed guide portion 3g in coil-end connecting portion 3b, but it is also possible to omit
Fixed guide portion 3g.
Moreover, Figure 18 is the explanation figure for the major part that Figure 10 is schematically shown from front.The elasticity in elastic deformation portion
The direction of displacement of movable guide portion caused by deformation is the reflex angle scope α that the end wires portion in movable guide portion that hangs over is formed
Direction, can be not necessarily the direction close to iron core.For example, in the case of embodiment 1, can by end wires portion pair
The extension method of dynamic guide portion is changed to one side from both sides, thus enables that movable guide portion and its dependency structure are rotated by 90 ° and structure
Into.
Therefore, the resilient force produced by the elastic deformation in elastic deformation portion is in the end wires for hanging over movable guide portion
The direction for the bad angular range β that portion is formed.In addition, the elastic deformation process of the manufacture method in the coil device of the present invention
In, make the direction displacement for the reflex angle scope α that movable guide portion formed to the end wires portion for hanging over movable guide portion.And
And, in cuttling, make the side for the bad angular range β that movable guide portion formed to the end wires portion for hanging over movable guide portion
To return.
In addition, in embodiment 1,2, winding portion 3a is configured with the inner side of iron core 2, but the present invention can also apply to
The stator of winding portion is configured with the outside of iron core.I.e., it is possible to be the structure for inverting Fig. 1,2 internal side diameter and outside diameter.Moreover,
It can also be the structure for expanding into banding.
Also, as the mode for implementing the present invention, it is illustrated by taking the stator of rotary transformer as an example, but certainly
Also it can apply the present invention to as such as electromagnetic actuators of movable core type that the coil dress of common stator can not be referred to as
Put.
