The fan frame 20, there is axle portion 22 and four of the base portion 21, one located at the base portion 21 through the base portion 21
Hole clipping 23；In the present embodiment, each hole clipping 23 of the fan frame 20, which is enclosed, is located at the axle portion 22；The wall surface of the hole of each hole clipping 23 of the fan frame 20
It is convexly equipped with a shoulder 231；Finally the radial convex of axle portion 22 of the fan frame 20 is provided with plural stopper 24.
The stator, group is located at the fan frame 20, and is shaped in the stator core 30 including a stator core 30 and one
Stator insulating frame 40.Wherein the stator core 30 is located on the annular portion including an annular portion 31, four for being placed on the axle portion 22
The flank 32 and the pole claw 33 located at the respectively flank 32 of 31 peripheries.The stator insulating frame 40 has one to be at least shaped in
The portion 41 and four that is dielectrically separated from of the flank 32 of annular portion 31 and four is connected to that this is dielectrically separated from portion 41 and clip is in the respectively hole clipping 23
Insulation clip rib 42；In the present embodiment, the portion 41 that is dielectrically separated from of the stator insulating frame 40 is more shaped in the stator core
30 pole claw 33, therefore, the stator insulating frame 40 are dielectrically separated from portion 41 with a local isolation for coating the annular portion 31
Annulus section 411, one coats the local isolation pole pawl section for coating the pole claw 33 of isolation rib section 412 and one of the respectively flank 32
413, and cause the line by the structure design of the stator insulating frame 40 when supplying 50 winding of coil after the stator insulating frame 40 shaping
Circle 50 is electrically insulated with the stator core 30；In addition, the end of each insulation clip rib 42 of the stator insulating frame 40 have one
In the hole clipping 23 and fasten in the hook part 421 of the shoulder 231；In addition, between each insulation clip rib 42 of the stator insulating frame 40
With an abutting part 43, the stator further includes one and is nested with the axle portion 22 and by only in the respectively abutting part 43 and the base portion 21
Between circuit board 60, the circuit board 60 is simultaneously electrical connected with coil 50；Finally, the stator core 30 is nested with the axle portion 22
Afterwards, its annular portion 31 is to only in the respectively stopper 24.
Described above is the configuration explanation of each main member of the embodiment of the present invention.Certain radiator fan further includes one turn
Son 70, the rotor 70 is axle portion 22 and the relative stator rotation for being hubbed on the fan frame 20, because the rotor 70 is known members, and
It makees flowing mode all with known identical, also the creation emphasis of non-invention, therefore the detailed construction for the component and start side
Formula is no longer described in detail.The present invention at least has following effects.
One, the present invention can provide a kind of stator and assemble firm cooling fan structure.
Because the present invention is that four hole clippings 23 are provided with the base portion 21 of the fan frame 20, and by the stator core 30 with
Both are integrally formed the stator insulating frame 40, and the stator insulating frame 40 is dielectrically separated from portion 41 in it and is formed with four insulation clip ribs
42, therefore, when the stator core 30 is nested with the axle portion 22 of the fan frame 20, the stator insulating frame 40 is nested with the fan frame simultaneously
20 axle portion 22, now, the stator insulating frame 40 are positioned at the hole clipping of the fan frame 20 by its corresponding clip of clip rib 42 that insulate
23, further it is in the hole clipping 23 and to be fastened by the hook part 421 of the respectively insulation clip rib 42 in the shoulder 231, makes
The stator (i.e. stator core 30 and the stator insulating frame 40) is more firmly installed on the axle portion 22 of the fan frame 20, prevents from radiating
Fan is hit or high temperature influences, and reduces the stator and departs from axle portion 22 in the fan frame 20.
Secondly, the present invention cooling fan structure of stator assembling time and labour saving a kind of can be provided.
Due to the present invention, by the stator core 30 and stator insulating frame 40, both are formed in one, and supply coil 50 after shaping
During winding, by the structure design of the stator insulating frame 40 coil 50 is electrically insulated with the stator core 30 so that this is fixed
Son is not necessary to carry out contraposition assembling to both the stator core 30 and stator insulating frame 40 again in assembling, to reach stator assembling
The purpose of time and labour saving.
It is noted that refer to again shown in Fig. 5 and Fig. 6, because the present invention more can be in the radial direction of axle portion 22 of the fan frame 20
It is convexly equipped with plural stopper 24, the annular portion 31 of the stator core 30 is to only in the respectively stopper 24, therefore, when the stator core
30 are nested with the axle portion 22 of the fan frame 20, the stator core 30 towards the direction of base portion 21 of the fan frame 20 displacement by the stator
The annular portion 31 of iron core 30 is supported only to be limited in the respectively stopper 24, and the stator core 30 is anti-towards the base portion 21 of the fan frame 20
The displacement in direction is then limited by the hole clipping 23 that the corresponding clip of the insulation clip rib 42 of the stator insulating frame 40 is positioned at the fan frame 20
Make, therefore, can more lift the stator (i.e. stator core 30 and the stator insulating frame 40) and be installed on the axle portion of the fan frame 20
22 fastness.
As shown in fig.9, in the present embodiment, two hole clippings 23 can be provided with the base portion 21 of the fan frame 20, and
The stator insulating frame 40 is dielectrically separated from portion 41 in it and is formed with two to correspond to insulation clip rib 42 of the clip in the hole clipping 23,
Use and reach another embodiment, the quantity of hole clipping 23 and the stator insulating frame 40 in the base portion 21 of certain fan frame 20 in
It is dielectrically separated from the quantity of insulation clip rib 42 of the shaping of portion 41 can be the plural quantity of three or other mutual respective amounts all
Can.
In summary, above-described embodiment and schema are only the preferred embodiments of the invention, when can not with restriction this
The scope of implementation is invented, the equivalent changes and modifications made such as according to scope of the present invention patent, should all belong to patent of the present invention
In the range of covering.
