Embodiment 1 please refers to shown in Fig. 1-Fig. 3, and the present embodiment provides a kind of insulation frameworks, comprising: what is be oppositely arranged is upper
Skeleton 1 and lower skeleton 2；
Upper skeleton 1 includes top ring 11 and multiple upper slot insulation portions, and multiple upper slot insulation portions are arranged at intervals at top ring 11
Towards on the end face of 2 side of lower skeleton, and along the axially extending of top ring 11.Wherein, the quantity in upper slot insulation portion, position and
Outer profile is arranged according to the jack adaptability on the iron core A of adaptation.And upper slot insulation portion and top ring 11 can be wholely set
Split settings, when being wholely set, the mode that injection molding can be used carries out integrated injection molding.In the present embodiment, upper slot insulation portion and upper end
Ring 11 is integrally formed.
Lower skeleton 2 includes lower loop 21 and descends slot insulation portion 22 correspondingly with multiple upper slot insulation portions, under multiple
Slot insulation portion 22 is arranged at intervals at lower loop 21 towards on the end face of 1 side of upper skeleton, and along the axially extending of lower loop 21.Under
End ring 21 and the set-up mode of lower slot insulation are identical as upper skeleton 1, can refer to above content, are not added and repeat herein.
The length in each group of corresponding upper slot insulation portion and the sum of the length in lower slot insulation portion 22 are equal, specifically, on
After skeleton 1 and lower skeleton 2 and iron core A complete assembly, the end in corresponding upper slot insulation portion and lower slot insulation portion 22, which contacts, is completed
Connection.And the sum of length in upper slot insulation portion and lower slot insulation portion 22 after connecting is identical as the length of iron core A in the axial direction.
It include multiple first slot insulation portion 12 and at least one second slot insulation portion 13, the second slot in multiple upper slot insulation portions
The length of insulation division 13 is greater than the length in the first slot insulation portion 12.
Insulation framework provided in this embodiment only need to be by multiple upper slots when wherein upper skeleton 1 is that iron core A is assembled
After length longer second slot insulation portion 13 is aligned with jack on iron core A in insulation division, after being inserted into it first in jack, due to more
Relative position between a upper slot insulation portion be it is fixed and corresponding with jack so that remaining 12 energy of the first slot insulation portion
Under the guidance in the second slot insulation portion 13, being not required to be aligned be can be inserted into jack.In this way, reducing upper skeleton 1 and iron core A
When assembly, the quantity in the upper slot insulation portion aligned reduces the assembly difficulty between upper skeleton 1 and iron core A, from
And it improves work efficiency.Correspondingly, due on lower skeleton 2, the length in lower slot insulation portion 22 corresponding with the second slot insulation portion 13
Degree will be lower than the length in its remaining slot insulation portion 22, it follows that being aligned when lower skeleton 2 and iron core A assemble
The quantity in lower slot insulation portion 22 also accordingly reduces, to reduce the assembly difficulty of lower skeleton 2 Yu iron core A, improves work effect
Rate.By above content as it can be seen that insulation framework provided in this embodiment, can reduce upper skeleton 1 and lower skeleton 2 and fill with iron core A
Timing, the quantity in the upper slot insulation portion and lower slot insulation portion 22 that are aligned reduce the whole assembly of insulation framework
Difficulty, to improve work efficiency.
In the present embodiment, it is illustrated with being adapted to the insulation framework of the iron core A with nine jacks, corresponding, upper slot is exhausted
The quantity in edge and lower slot insulation portion 22 is also nine.
When concrete application, referring to figure 2. shown in-Fig. 3, the quantity in the second slot insulation portion 13 can be one, correspondingly, upper
When skeleton 1 and iron core A are assembled, a second slot insulation portion 13 need to only be aligned in jack, upper skeleton 1 can be completed
Whole contraposition, greatly reduce assembly difficulty.
In other embodiments, in order to avoid because upper slot insulation portion assembly when, entire upper skeleton 1 is oriented to alone
When damaged because stress is excessive.Second slot insulation portion 13 may be alternatively provided as multiple, and the length phase in multiple second slot insulation portion 13
Together, so that multiple second slot insulation portion 13 is shared the active force that guiding is constantly subject to jointly, avoid generating in assembling process
Damage.Specifically, the second slot insulation portion 13 can be three.
Further, in other embodiments, in order to further decrease the assembly difficulty of lower skeleton 2, multiple upper slot insulation
It further include at least one third slot insulation portion in portion, the length of the length in third slot insulation portion less than the first slot insulation portion 12.I.e.
It is presented as that the length in the lower slot insulation portion 22 corresponding with third slot insulation portion in lower skeleton 2 is greater than remaining lower slot insulation portion
22.Make lower skeleton 2 when assembling with iron core A, whole lead can be carried out by lower slot insulation portion 22 corresponding with third slot insulation portion
To herein reduction assembly difficulty, principle can refer to above, be not added and repeat.
Further, the ordered series of numbers in third slot insulation portion also can be multiple for one, and work as third slot insulation portion (in figure not
Show) quantity be it is multiple when, the length in multiple third slot insulation portion is identical.
It further, in a preferred embodiment, is the assembly difficulty for reducing upper skeleton 1 and lower skeleton 2 as far as possible, second
Slot insulation portion 13 and third slot insulation portion are one, and the length in multiple first slot insulation portion 12 is identical.In this way, making upper
When skeleton 1 and lower skeleton 2 are that iron core A is assembled, a upper slot insulation portion or lower slot insulation portion 22 need to only be carried out pair
Position, to improve working efficiency as far as possible.
Further, referring to figure 2. shown in-Fig. 3, applied in the insulation framework of any of the above-described, corresponding upper slot is exhausted
Connection structure is equipped between edge and lower slot insulation portion 22, for connecting upper slot insulation portion and lower slot insulation portion 22.By setting
Connection structure is set, when so that upper skeleton 1 and lower skeleton 2 being that iron core A completes assembly, upper skeleton 1 and lower skeleton 2 pass through connection knot
Structure realizes relatively fixed, the stability of reinforced insulation skeleton, avoids being detached from iron core A.
Further, referring to figure 2. shown in-Fig. 3, in the present embodiment, connection structure includes mutually matched male connector portion
With female portion, female portion is set to end of the slot insulation portion far from top ring 11, and it is remote that male connector portion is set to lower slot insulation portion 22
End from lower loop 21.In other embodiments, the common connection structure such as buckle structure can also be used in connection structure.
Further, in the present embodiment, under the premise of guaranteeing isolation of the slot insulation portion to iron core A and winding, reduce
Influence of the wall thickness to magnetic field in stator.In the present embodiment, the wall thickness in upper slot insulation portion and lower slot insulation portion 22 is 0.5mm-
1mm.Preferably, the wall thickness in upper slot insulation portion and lower slot insulation portion 22 is 0.75mm.
The present embodiment also provides a kind of stator, and stator includes insulation framework described in any of the above embodiments.
The present embodiment also provides a kind of motor, the above-mentioned stator of motor.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
