第一實施例First embodiment

在本公開的第一實施例中,提供了一種定子1a。圖1為本公開第一實施例定子的平面圖。如圖1所示,本公開定子1a包括:鐵芯2(即定子芯),繞線3,電路板4,端子插針5,引線6和絕緣體7。定子1a構成馬達的一部分。In the first embodiment of the present disclosure, a stator 1a is provided.

As shown in FIG. 1, the stator 1 a of the present disclosure includes: an iron core 2 (ie, a stator core), a winding 3, a circuit board 4, a terminal pin 5, a lead 6 and an insulator 7. The stator 1a constitutes a part of the motor.

鐵芯2為由位於定子1a外周的磁軛部8與從磁軛部8向內周側突出的齒部(圖中無標記)一體成型形成、由多個分割鐵芯呈環狀連接形成。鐵芯2可由鄰接的磁軛部8組成的呈直線狀的多個分割鐵芯加工成環狀而成,也可以由多個單獨個體的分割鐵芯的磁軛部8連接成環形所形成。鐵芯2外周大體呈圓柱形,包括位於圓柱形一邊的面形成的頂面、與頂面相對的底面、以及在外周側連接頂面與底面的外周側面。另外,鐵芯2還包括連接形成馬達轉軸的頂面中心周圍與同樣形成馬達轉軸的底面中心周圍的圓柱形的空間,上述空間的周圍由鐵芯2的內周側面形成。換言之,從軸方向上看,鐵芯2具有呈圓環形狀的頂面及底面,圖中未示出的轉子位於軸周圍的空間。The iron core 2 is formed by integrally molding a yoke portion 8 located on the outer circumference of the stator 1a and a tooth portion (not shown in the figure) protruding from the yoke portion 8 to the inner circumference side, and is formed by connecting a plurality of divided iron cores in a ring shape. The iron core 2 may be formed by processing a plurality of linear split iron cores composed of adjacent yoke portions 8 into a ring shape, or may be formed by connecting a plurality of individual split iron core yoke portions 8 in a ring shape. The outer periphery of the iron core 2 is generally cylindrical, and includes a top surface formed by a surface located on one side of the cylindrical shape, a bottom surface opposite to the top surface, and an outer peripheral side surface connecting the top surface and the bottom surface on the outer peripheral side. In addition, the iron core 2 also includes a cylindrical space connecting the center of the top surface forming the motor shaft and the center of the bottom surface also forming the motor shaft. The circumference of the space is formed by the inner peripheral side surface of the iron core 2. In other words, viewed from the axial direction, the iron core 2 has an annular top surface and a bottom surface, and a rotor not shown in the figure is located in the space around the shaft.

絕緣體7主要覆蓋從鐵芯2的磁軛部8到齒部的範圍。繞線3以絕緣體7為介(隔著絕緣體7)纏繞在多個齒部上,其中絕緣體7使鐵芯2與繞線3之間電氣絕緣。絕緣體7和鐵芯2相同,呈與分割鐵芯相對應的環狀。環狀的絕緣體7外周側設有用於固定引線6的突出部9,以及如圖2所示的用於確定電路板位置的突起部10a及10b。The insulator 7 mainly covers the range from the yoke portion 8 of the iron core 2 to the tooth portion. The winding wire 3 is wound around a plurality of teeth with an insulator 7 as a medium (interposing the insulator 7 ). The insulator 7 electrically insulates the iron core 2 and the winding wire 3. The insulator 7 is the same as the iron core 2 and has a ring shape corresponding to the split iron core. On the outer peripheral side of the ring-shaped insulator 7, there are provided protrusions 9 for fixing the leads 6, and protrusions 10a and 10b for positioning the circuit board as shown in FIG.

繞線3是由銅或者鋁合金為主要材料所構成的導線,且以絕緣體7為介纏繞在鐵芯2上。另外,繞線3的繞線規格可根據要求的規格而改變。The winding wire 3 is a wire made of copper or aluminum alloy as the main material, and is wound on the iron core 2 through an insulator 7. In addition, the winding specifications of the winding 3 can be changed according to the required specifications.

電路板4通過連接多個電性觸點,使繞線3與例如逆變電路等外部電路進行連接。電路板4的外廓呈中心角約為160°的中空圓形一部分,即部分的圓環狀。電路板4與鐵芯2的中心軸20同心,且設置在垂直於中心軸20的平面上、從中心軸20向鐵芯2方向一定距離的位置上。電路板4固定在絕緣體7的頂面側端部且處於與圓環狀一致的位置,即被固定在頂面的外周部上,並且電路板4在其面向絕緣體7及鐵芯2的相反側的表面19上與引線6連接,並且引線6從電路板4引出。如圖3所示,電路板4還包括與絕緣體7上的突起部10a、10b相適配的缺口15a、15b。The circuit board 4 connects the winding 3 to an external circuit such as an inverter circuit by connecting a plurality of electrical contacts. The outer profile of the circuit board 4 is a part of a hollow circle with a center angle of about 160°, that is, a part of an annular shape. The circuit board 4 is concentric with the central axis 20 of the iron core 2 and is arranged on a plane perpendicular to the central axis 20 at a certain distance from the central axis 20 to the iron core 2. The circuit board 4 is fixed on the top side end of the insulator 7 and is in a position consistent with the ring shape, that is, fixed on the outer periphery of the top surface, and the circuit board 4 is on the opposite side of the insulator 7 and the iron core 2 The surface 19 is connected with the lead 6 and the lead 6 is led out from the circuit board 4. As shown in FIG. 3, the circuit board 4 further includes notches 15a, 15b that fit the protrusions 10a, 10b on the insulator 7.

為了把外部電力輸送到電路板4上,引線6的末端相應地與電路板4的電觸點相連接。In order to transmit external power to the circuit board 4, the ends of the leads 6 are connected to the electrical contacts of the circuit board 4 accordingly.

端子插針5固定在絕緣體7的上面,即絕緣體7上與電路板4相對的面上,並且向電路板4的所在方向豎立且與中心軸20平行設置,即沿軸方向設置。主要由導電材料形成的端子插針5通過分別與繞線3以及電路板4上的銅箔進行電路連接,使繞線3與電路板4之間進行電路連接。The terminal pins 5 are fixed on the upper surface of the insulator 7, that is, the surface of the insulator 7 opposite to the circuit board 4, and are erected in the direction of the circuit board 4 and arranged parallel to the central axis 20, that is, arranged along the axial direction. The terminal pins 5 mainly formed of conductive materials are electrically connected to the winding wire 3 and the copper foil on the circuit board 4 respectively, so that the winding wire 3 and the circuit board 4 are circuit connected.

以下參考圖2,對絕緣體7進行詳細的說明。圖2為本公開實施例絕緣體的斜視外觀圖。The insulator 7 will be described in detail below with reference to FIG. 2. Fig. 2 is a perspective view of an insulator according to an embodiment of the disclosure.

絕緣體7的突出部9呈T字型,突出部9設於絕緣體7的軸方向上的位於端部附近且垂直於中心軸20的面上、即設於絕緣體7的頂面(或底面)上。The protrusion 9 of the insulator 7 is T-shaped, and the protrusion 9 is provided on the surface of the insulator 7 near the end and perpendicular to the central axis 20 in the axial direction of the insulator 7, that is, on the top surface (or bottom surface) of the insulator 7 .

突出部9以絕緣體7環狀的最外周的絕緣體外徑11為起點更向外周側凸出,即向磁軛部8的方向凸出。突出部9從頂面觀察呈T字狀,T字狀的頭部在突出部9的外周側上形成限制部21,T字狀的腳部與絕緣體外徑11相連形成根部22,並從絕緣體7向外周側突出。限制部21從根部22的外周側端部向鐵芯2環狀的切線方向兩側突出。由於限制部21從根部22突出,從而在突出部9上形成了收縮的部分。另外,優選的,根部22在切線方向的寬度比引線6的寬度小。突出部9在絕緣體7的軸方向上具有足夠強度的厚度,且設有固定平面13。The protruding portion 9 protrudes further to the outer peripheral side from the outermost insulator outer diameter 11 of the ring-shaped insulator 7 as a starting point, that is, protrudes in the direction of the yoke portion 8. The protrusion 9 is T-shaped when viewed from the top surface. The T-shaped head forms a restricting portion 21 on the outer peripheral side of the protrusion 9, and the T-shaped leg is connected to the outer diameter of the insulator 11 to form a root 22, and is separated from the insulator 7 protruding to the outer peripheral side. The restriction portion 21 protrudes from the outer peripheral side end portion of the root portion 22 to both sides in the tangential direction of the ring shape of the iron core 2. Since the restricting portion 21 protrudes from the root portion 22, a contracted portion is formed on the protruding portion 9. In addition, it is preferable that the width of the root 22 in the tangential direction is smaller than the width of the lead 6. The protrusion 9 has a sufficient thickness in the axial direction of the insulator 7 and is provided with a fixing plane 13.

固定平面13是突出部9上在絕緣體7的軸方向上,高於位於佈置了電路板4的絕緣體7的頂面上的外徑側的絕緣體外徑側端面12與電路板4的厚度相同的高度而形成的平面。The fixed plane 13 is on the protrusion 9 in the axial direction of the insulator 7, which is higher than the insulator outer diameter side end surface 12 on the outer diameter side of the top surface of the insulator 7 on which the circuit board 4 is arranged, and the thickness of the circuit board 4 is the same. A plane formed by height.

另外,在絕緣體外徑側端面12上位於突出部9的內周側處設有沿絕緣體7的軸方向突出的突起部10a,以及在佈置了電路板4的頂面的內徑側的絕緣體內徑側端面14上設有從絕緣體7的上面向絕緣體7的軸方向突出的突起部10b。當電路板4裝配到絕緣體7上時,突起部10a、突起部10b在電路板4的半徑方向及圓周方向上限制電路板4的移動。作為本實施的一種具體實施方式,突起部10a設置在絕緣體外徑側端面12上且在突出部9圓周方向上的中間。同時,突起部10b則設置在絕緣體內徑側端面14上並與突起部10a相對。就是說突起部10b設置在突起部10a和中心軸20的連線上。In addition, a protrusion 10a protruding in the axial direction of the insulator 7 is provided on the end surface 12 on the outer diameter side of the insulator on the inner circumference side of the protrusion 9, and in the insulator on the inner diameter side of the top surface of the circuit board 4 The radial end surface 14 is provided with a protrusion 10 b protruding from the upper surface of the insulator 7 in the axial direction of the insulator 7. When the circuit board 4 is assembled on the insulator 7, the protrusions 10a and 10b restrict the movement of the circuit board 4 in the radial direction and the circumferential direction of the circuit board 4. As a specific embodiment of this embodiment, the protrusion 10 a is provided on the outer end surface 12 of the insulator and in the middle of the protrusion 9 in the circumferential direction. At the same time, the protrusion 10b is provided on the radial side end surface 14 of the insulator and opposes the protrusion 10a. That is, the protrusion 10b is provided on the line connecting the protrusion 10a and the central axis 20.

以下參考圖3以及圖4,對電路板4裝配在絕緣體7上後的情況進行詳細的說明。圖3為定子的局部平面圖,圖4為定子的A-A截面圖。Hereinafter, referring to FIG. 3 and FIG. 4, the situation after the circuit board 4 is assembled on the insulator 7 will be described in detail. Fig. 3 is a partial plan view of the stator, and Fig. 4 is an A-A cross-sectional view of the stator.

為將電路板4固定在絕緣體7上,電路板4設置有從部分圓環形狀的內徑和外徑向電路板4內部凹陷的缺口,分別包括缺口15a和缺口15b。缺口15a、15b的位置以及大小與絕緣體7上設置的突起部10a和10b相對應。也就是說,裝配電路板4時,通過使電路板4上的缺口15a和缺口15b與絕緣體7上的突起部10a和10b分別卡合,從而在直徑方向上以及圓周方向上確定電路板的位置。此外,通過使電路板4和絕緣體外徑側端面12以及絕緣體內徑側端面14相接以決定電路板4在軸方向上的位置。在裝配了電路板4的狀態下,突出部9比電路板4的外周更向外周側突出,但比鐵芯2更位於內周側。另外,由於固定平面13在軸方向上,突出於絕緣體外徑側端面12與電路板4的厚度23相同的高度,因此突出部9的固定平面13與電路板4的表面19在同一平面上。In order to fix the circuit board 4 on the insulator 7, the circuit board 4 is provided with notches recessed from the inner and outer radial portions of the circular ring shape, including notches 15a and 15b, respectively. The positions and sizes of the notches 15 a and 15 b correspond to the protrusions 10 a and 10 b provided on the insulator 7. That is to say, when assembling the circuit board 4, the notches 15a and 15b on the circuit board 4 are engaged with the protrusions 10a and 10b on the insulator 7, so as to determine the position of the circuit board in the diameter direction and the circumferential direction. . In addition, the position of the circuit board 4 in the axial direction is determined by contacting the circuit board 4 with the insulator outer diameter side end surface 12 and the insulator inner diameter side end surface 14. In the state where the circuit board 4 is assembled, the protruding portion 9 protrudes further to the outer peripheral side than the outer periphery of the circuit board 4 but is located on the inner peripheral side than the iron core 2. In addition, since the fixing plane 13 protrudes from the end surface 12 on the outer diameter side of the insulator at the same height as the thickness 23 of the circuit board 4 in the axial direction, the fixing plane 13 of the protrusion 9 and the surface 19 of the circuit board 4 are on the same plane.

在以上描述的結構中,在突出部9的限制部21內周側的收縮部位上,通過使用綁繩或紮帶等拘束物將橫跨固定平面13與表面19配置的引線6與根部22緊固在一起,使引線6固定在絕緣體7上,即引線6被固定在固定平面13上。In the structure described above, at the constricted portion on the inner peripheral side of the restricting portion 21 of the protruding portion 9, the lead wire 6 and the root portion 22 arranged across the fixed plane 13 and the surface 19 are tightened by using a binding rope or tie. Fix them together so that the lead 6 is fixed on the insulator 7, that is, the lead 6 is fixed on the fixing plane 13.

通過上述結構,即使引線6受到拉扯或馬達運轉的振動等所產生的外力,由於力被絕緣體7吸收,因此不會對與引線6連接的電路板4產生影響。因此,由於有多個電氣性連接的部位而比絕緣體7更脆弱的電路板4上的電氣性連接部位能夠得到保護。With the above structure, even if the lead 6 is pulled or the external force generated by the vibration of motor operation, etc., the force is absorbed by the insulator 7, so that it does not affect the circuit board 4 connected to the lead 6. Therefore, the electrical connection locations on the circuit board 4 that are more fragile than the insulator 7 due to the multiple electrical connection locations can be protected.

此外,因為突出部9比電路板4的外周更向外周突出,所以在根部22上使用綁繩或紮帶捆綁時,電路板和鐵芯2並不會影響裝配。因此,引線6和根部22的結合更加容易。In addition, because the protruding portion 9 protrudes more to the outer periphery than the outer periphery of the circuit board 4, when the root portion 22 is tied with a tie or tie, the circuit board and the iron core 2 will not affect the assembly. Therefore, the bonding of the lead 6 and the root 22 is easier.

由於電路板4的表面19和固定平面13在同一個水平面上,所以引線6能夠水平設置,不會因為彎曲而對引線6造成額外的負荷。Since the surface 19 of the circuit board 4 and the fixing plane 13 are on the same horizontal plane, the lead 6 can be arranged horizontally, and no additional load will be imposed on the lead 6 due to bending.

由於引線6被綁繩或紮帶固定在限制部21內周側的收縮部位上,可以防止綁繩或紮帶向外周方向拔出,使得固定的可靠性提高。Since the lead wire 6 is fixed on the contraction part on the inner peripheral side of the restricting portion 21 by a tie cord or a tie, the tie cord or tie can be prevented from being pulled out in the outer peripheral direction, so that the reliability of the fixation is improved.

另外,由於根部22在切線方向上的寬度比引線6的直徑小,所以被固定後的引線6圓切線方向上的移動受到約束,從而提高引線6的固定強度。In addition, since the width of the root 22 in the tangential direction is smaller than the diameter of the lead 6, the fixed movement of the lead 6 in the tangential direction is restricted, thereby improving the fixing strength of the lead 6.

由於絕緣體7從突出部9的內周側中央向中心軸的直線上設有固定電路板4的突起部10a、10b,所以被固定後的電路板4在切線方向上的移動受到限制,從而提高電路板4在絕緣體7上的固定強度。Since the insulator 7 is provided with projections 10a, 10b for fixing the circuit board 4 on a straight line from the center of the inner peripheral side of the protruding portion 9 to the central axis, the movement of the fixed circuit board 4 in the tangential direction is restricted, thereby improving The fixing strength of the circuit board 4 on the insulator 7.

第二實施例Second embodiment

本公開第二實施例提供了一種定子1b。以下,如圖5所示,將主要針對第二實施例中的定子1b與第一實旋例中的定子1a不同的特徵進行說明。圖5為本公開的第二實施例中的定子1b的平面圖。The second embodiment of the present disclosure provides a stator 1b. Hereinafter, as shown in FIG. 5, the description will mainly focus on the different features of the stator 1b in the second embodiment from the stator 1a in the first embodiment. FIG. 5 is a plan view of the stator 1b in the second embodiment of the disclosure.

定子1b包括鐵芯2、繞線3、電路板4、端子插針5、以及引線6和絕緣體7。環狀的絕緣體7外周側設有用於固定引線6的突出部9。The stator 1b includes an iron core 2, a winding wire 3, a circuit board 4, a terminal pin 5, and a lead 6 and an insulator 7. A protrusion 9 for fixing the lead 6 is provided on the outer peripheral side of the ring-shaped insulator 7.

如圖6所示,絕緣體7的突出部9呈T字型,在本實施例中,突出部9與第一實施例中所記載的突出部9形狀不同。並且,在本實施例中,用於確定電路板位置的突起部10a及突起部10b的位置與第一實施例所記載的位置不同。針對以上不同點,將於後面進行詳細描述。As shown in FIG. 6, the protrusion 9 of the insulator 7 has a T-shape. In this embodiment, the protrusion 9 has a different shape from the protrusion 9 described in the first embodiment. In addition, in this embodiment, the positions of the protruding portion 10a and the protruding portion 10b for determining the position of the circuit board are different from the positions described in the first embodiment. The above differences will be described in detail later.

電路板4通過連接多個電性觸點,使繞線3與例如逆變電路等外部電路進行連接。逆變電路等外部電路位於電路板4上。電路板4的外廓呈中心角約為160°的中空圓形一部分,即部分的圓環狀,或者說,電路板4為圓心角約為160°的圓弧形板體。電路板4固定在絕緣體7的頂面側端部上,即被放置並固定於頂面的外周部上,或者說,電路板4位於絕緣體7的頂面的外側,所述外側為沿中心軸20遠離絕緣體7頂面的一側。如圖7所示,電路線4還包括與第一實施例不同的缺口15a及缺口15b。The circuit board 4 connects the winding 3 to an external circuit such as an inverter circuit by connecting a plurality of electrical contacts. External circuits such as inverter circuits are located on the circuit board 4. The outer profile of the circuit board 4 is a part of a hollow circle with a central angle of about 160°, that is, a part of an annular shape, or in other words, the circuit board 4 is an arc-shaped board body with a central angle of about 160°. The circuit board 4 is fixed on the top surface side end of the insulator 7, that is, is placed and fixed on the outer periphery of the top surface, or in other words, the circuit board 4 is located on the outside of the top surface of the insulator 7, and the outside is along the central axis 20 is away from the side of the top surface of the insulator 7. As shown in FIG. 7, the circuit line 4 further includes a notch 15a and a notch 15b that are different from the first embodiment.

以下,參考圖6,對絕緣體7進行詳細說明。圖6為本實施例中的絕緣體的斜視外觀圖。Hereinafter, referring to FIG. 6, the insulator 7 will be described in detail. Fig. 6 is a perspective view of the insulator in this embodiment.

突出部9設於絕緣體7的軸方向上的位於端部附近且垂直於中心軸20的面上;即突出部9設於絕緣體7的外壁面上,所述外壁面為絕緣體7的環繞中心軸20的外周面。The protrusion 9 is provided on the surface of the insulator 7 near the end and perpendicular to the central axis 20 in the axial direction; that is, the protrusion 9 is provided on the outer wall surface of the insulator 7, and the outer wall surface is the surrounding central axis of the insulator 7 20's outer peripheral surface.

突出部9以絕緣體7環狀的最外周的絕緣體外徑11為起點更向外周側凸出、即向磁軛部8的方向凸出。即突出部9由絕緣體7外壁面向外周側凸出,所述外周側是指沿絕緣體7的徑向遠離絕緣體7外壁面的一側。The protruding portion 9 protrudes further toward the outer peripheral side, that is, in the direction of the yoke portion 8 starting from the outermost insulator outer diameter 11 of the ring-shaped insulator 7. That is, the protrusion 9 protrudes from the outer wall surface of the insulator 7 to the outer peripheral side, and the outer peripheral side refers to the side away from the outer wall surface of the insulator 7 in the radial direction of the insulator 7.

突出部9從頂面觀察呈T字狀,即沿中心軸20從絕緣體7的頂面向底面觀察,突出部9呈T字狀。The protrusion 9 is T-shaped when viewed from the top surface, that is, when viewed from the top surface of the insulator 7 along the central axis 20, the protrusion 9 is T-shaped.

T字狀的頭部在突出部9的外周側上形成限制部21,所述外周側是指沿絕緣體7的徑向遠離絕緣體7外壁面的一側。T字狀的腳部與絕緣體外徑11相連形成根部22,並從絕緣體7向外周側突出。即根部22從絕緣體7的外壁面向外周側凸出。也就是說,限制部21連接根部22,根部22連接絕緣體7的外壁面。突出部9在絕緣體7的軸方向上具有足夠強度的厚度,且設有固定平面13。即突出部9中心軸20的方向上具有足夠強度的厚度。The T-shaped head forms a restricting portion 21 on the outer peripheral side of the protrusion 9, and the outer peripheral side refers to the side away from the outer wall surface of the insulator 7 in the radial direction of the insulator 7. The T-shaped leg is connected to the outer diameter 11 of the insulator to form a root 22 and protrudes from the insulator 7 to the outer peripheral side. That is, the root portion 22 protrudes from the outer wall surface of the insulator 7 to the outer peripheral side. That is, the restricting portion 21 is connected to the root portion 22 and the root portion 22 is connected to the outer wall surface of the insulator 7. The protrusion 9 has a sufficient thickness in the axial direction of the insulator 7 and is provided with a fixing plane 13. That is, the protrusion 9 has a sufficient thickness in the direction of the central axis 20.

與第一實施例所記載的形狀不同,本實施例中,突出部9上的固定平面13包括在外周方向上向鐵芯2彎曲的彎曲面31。即固定平面13包括沿絕緣體7的徑向、向遠離絕緣體7外壁面的方向,向鐵芯2彎曲的彎曲面31。也就是說,固定平面13靠近絕緣體外徑11的部分為與電路板4的背面30平行的平面,如圖8所示,而遠離絕緣體外徑11的部分向下並向鐵芯2彎曲。即固定平面13包括平面部分和彎曲部分。平面部分平行於電路板4的背面30,或者說垂直於中心軸20,而彎曲部分沿絕緣體7的徑向、向遠離絕緣體7外壁面的方向向鐵芯2彎曲。Different from the shape described in the first embodiment, in this embodiment, the fixing plane 13 on the protrusion 9 includes a curved surface 31 that is curved toward the core 2 in the outer circumferential direction. That is, the fixed plane 13 includes a curved surface 31 that curves toward the iron core 2 in a direction away from the outer wall surface of the insulator 7 in the radial direction of the insulator 7. That is, the portion of the fixing plane 13 close to the outer diameter 11 of the insulator is a plane parallel to the back surface 30 of the circuit board 4, as shown in FIG. 8, and the portion away from the outer diameter 11 of the insulator is bent downward and toward the core 2. That is, the fixed plane 13 includes a flat portion and a curved portion. The plane part is parallel to the back surface 30 of the circuit board 4, or perpendicular to the central axis 20, and the bent part is bent toward the iron core 2 along the radial direction of the insulator 7 and away from the outer wall surface of the insulator 7.

限制部21從根部22的外周側端部向鐵芯2環狀的切線方向兩側突出。即限制部21沿鐵芯2的外壁面的切線從根部22的兩側突出,鐵芯2的外壁面的切線垂直於中心軸20。由於限制部21從根部22突出,限制部21與根部22在突出部9上形成了收縮的部分,即根部22成為了突出部9的收縮部分。The restriction portion 21 protrudes from the outer peripheral side end portion of the root portion 22 to both sides in the tangential direction of the ring shape of the iron core 2. That is, the restricting portion 21 protrudes from both sides of the root portion 22 along the tangent line of the outer wall surface of the iron core 2, and the tangent line of the outer wall surface of the iron core 2 is perpendicular to the central axis 20. Since the restriction portion 21 protrudes from the root portion 22, the restriction portion 21 and the root portion 22 form a constricted portion on the protrusion 9, that is, the root portion 22 becomes a constricted portion of the protrusion 9.

突起部10a設於絕緣體7的絕緣體外徑側端面12上的突出部9的周方向的兩端上,且在軸方向上突出。即絕緣體7的靠近其外壁面的一端沿中心軸20形成兩個側壁,兩個側壁分別位於突出部9的周向兩側,側壁頂端各形成一個絕緣體外徑側端面12,突起部10a由每個絕緣體外徑側端面12沿中心軸20突出。The protrusions 10a are provided on both ends of the protruding portion 9 on the insulator outer diameter side end surface 12 of the insulator 7 in the circumferential direction, and protrude in the axial direction. That is, the end of the insulator 7 close to its outer wall surface forms two side walls along the central axis 20. The two side walls are located on both sides of the protruding portion 9 in the circumferential direction. The top ends of the side walls each form an outer diameter side end surface 12 of the insulator. The end surface 12 on the outer diameter side of the insulator protrudes along the central axis 20.

另外,在絕緣體7的絕緣體內徑側端面14上,距離突出部9周方向的兩端相同距離的遠處設有突起部10b,且突起部10b在軸方向上突出。所謂遠處,即指以突出部9為中心,兩個突起部10b之間的距離比兩個突起部10a之間的距離更大。In addition, on the radial side end surface 14 of the insulator 7 of the insulator 7, a protrusion 10b is provided at the same distance from both ends in the circumferential direction of the protrusion 9 and the protrusion 10b protrudes in the axial direction. The so-called far distance means that with the protrusion 9 as the center, the distance between the two protrusions 10b is greater than the distance between the two protrusions 10a.

即絕緣體7的靠近其內壁面的一端沿中心軸20形成絕緣體內徑側端面14,兩個突起部10b從絕緣體內徑側端面14沿中心軸20突出,兩個突起部10b分別位於突出部9的周向兩側,兩個突起部10b之間的周向距離大於兩個突起部10a之間的周向距離。That is, the end of the insulator 7 close to its inner wall surface forms the inner radial side end surface 14 of the insulator along the central axis 20. Two protrusions 10b protrude from the inner radial end surface 14 of the insulator along the central axis 20, and the two protrusions 10b are respectively located at the protrusion 9 On both sides of the circumferential direction, the circumferential distance between the two protrusions 10b is greater than the circumferential distance between the two protrusions 10a.

當電路板4裝配到絕緣體7上時,突起部10a、突起部10b在電路板4的半徑方向及圓周方向上限制電路板4的移動。在本實施例中,突起部10a設於絕緣體外徑側端面12上的比突出部9周方向上的比根部22更寬的位置上。即兩個突起部10a分別位於突出部9的周向兩側,或者說,兩個突起部10a之間的周向距離大於根部22的周向長度。另外,突起部10b設於絕緣部內徑側端面14上以根部22為中心在周方向上向兩側各轉動45°的位置上。即兩個突起部10b的周向位置與根部22的周向位置均相差45°。When the circuit board 4 is assembled on the insulator 7, the protrusions 10a and 10b restrict the movement of the circuit board 4 in the radial direction and the circumferential direction of the circuit board 4. In this embodiment, the protruding portion 10 a is provided on the outer end surface 12 of the insulator at a position wider than the root portion 22 in the circumferential direction of the protruding portion 9. That is, the two protrusions 10a are located on both sides of the protrusion 9 in the circumferential direction, in other words, the circumferential distance between the two protrusions 10a is greater than the circumferential length of the root 22. In addition, the protruding portion 10b is provided on the inner diameter side end surface 14 of the insulating portion at a position that is rotated 45° on both sides in the circumferential direction with the root portion 22 as the center. That is, the circumferential position of the two protrusions 10b and the circumferential position of the root 22 are both different by 45°.

以下將參考圖7及圖8,對電路板4安裝在絕緣體7時進行詳細說明。圖7為定子的部分平面圖,圖8為圖7所示的定子1b的A-A截面圖。Hereinafter, referring to FIG. 7 and FIG. 8, a detailed description will be given when the circuit board 4 is mounted on the insulator 7. Fig. 7 is a partial plan view of the stator, and Fig. 8 is an A-A cross-sectional view of the stator 1b shown in Fig. 7.

為將電路板4固定在絕緣體7上,電路板4設置有從部分圓環形狀的內徑和外徑向電路板4內部凹陷的缺口,分別包括缺口15a及缺口15b。即缺口15a開設於電路板4的半徑較大的側邊,缺口15b開設於電路板4的半徑較小的側邊。缺口15a及缺口15b的位置及大小與絕緣體7上設置的突起部10a與10b相對應。也就是說,裝配電路板4時,通過使電路板4上的缺口15a、缺口15b與絕緣體7上的突起部10a和10b分別卡合,從而在直徑方向上以及圓周方向上確定電路板4的位置。此外,通過使電路板4和絕緣體外徑側端面12及絕緣體內徑側端面14相接以決定電路板4在軸方向上的位置。在安裝了電路板4的狀態下,突出部9比電路板4的外周更向外周側突出,但比鐵芯2更位於內周側。即突出部9比電路板4的半徑較大的側邊更向外周側突出,鐵芯2的外壁面位於突出部9的外周側。In order to fix the circuit board 4 on the insulator 7, the circuit board 4 is provided with notches recessed from the inner and outer radial portions of the circular ring shape, including notches 15a and 15b, respectively. That is, the notch 15a is opened on the side of the circuit board 4 with a larger radius, and the notch 15b is opened on the side of the circuit board 4 with a smaller radius. The positions and sizes of the notch 15a and the notch 15b correspond to the protrusions 10a and 10b provided on the insulator 7. That is to say, when assembling the circuit board 4, the notches 15a and 15b on the circuit board 4 are engaged with the protrusions 10a and 10b on the insulator 7, respectively, so as to determine the diameter of the circuit board 4 in the diameter direction and the circumferential direction. position. In addition, the position of the circuit board 4 in the axial direction is determined by contacting the circuit board 4 with the end surface 12 on the outer diameter side of the insulator and the end surface 14 on the inner diameter side of the insulator. In the state where the circuit board 4 is mounted, the protruding portion 9 protrudes further to the outer peripheral side than the outer periphery of the circuit board 4 but is located on the inner peripheral side than the iron core 2. That is, the protruding portion 9 protrudes further to the outer peripheral side than the side with a larger radius of the circuit board 4, and the outer wall surface of the iron core 2 is located on the outer peripheral side of the protruding portion 9.

電路板4在其面向絕緣體7及鐵芯2的背面30上與引線6連接。突出部9上的固定平面13在軸方向上,比絕緣體外徑側端面12、即電路板4的背面30,向鐵芯2一側偏離與引線6的厚度同樣的距離,即沿中心軸20的方向,固定平面13與絕緣體外徑側端面12和電路板4的背面30的軸向距離,等於引線6的厚度,所述厚度是指沿中心軸20的長度。因此,突出部9的固定平面13位於電路板4上的背面30的下方。The circuit board 4 is connected to the lead 6 on its back 30 facing the insulator 7 and the iron core 2. The fixed plane 13 on the protruding portion 9 is offset from the end surface 12 on the outer diameter side of the insulator, that is, the back surface 30 of the circuit board 4, to the core 2 side by the same distance as the thickness of the lead wire 6, that is, along the central axis 20. The axial distance between the fixed plane 13 and the outer end surface 12 of the insulator and the back surface 30 of the circuit board 4 is equal to the thickness of the lead 6, and the thickness refers to the length along the central axis 20. Therefore, the fixing plane 13 of the protrusion 9 is located below the back surface 30 on the circuit board 4.

由此,當引線6固定在固定平面13上時,引線6在軸方向上位於固定平面13與電路板4的背面30之間。引線6在周方向上,被兩個突起部10a夾持固定。因此,與第一實施例相比,本實施例中,引線6沒有固定在表面19上,因此,到表面19為止即為定子1b的整體高度,即定子1b的整體高度到表面19為止,由此可以降低馬達的整體高度。Thus, when the lead 6 is fixed on the fixing plane 13, the lead 6 is located between the fixing plane 13 and the back surface 30 of the circuit board 4 in the axial direction. The lead wire 6 is sandwiched and fixed by two protrusions 10a in the circumferential direction. Therefore, compared with the first embodiment, in this embodiment, the lead wire 6 is not fixed on the surface 19, therefore, the entire height of the stator 1b up to the surface 19, that is, the overall height of the stator 1b up to the surface 19, is determined by This can reduce the overall height of the motor.

本實施例的上述結構中,在突出部9的限制部21的內周側的收縮部位上,通過使用綁繩或紮帶等拘束物將橫跨固定平面13的引線6與根部22緊固在一起,使引線6被固定在絕緣體7上。In the above-mentioned structure of this embodiment, at the constricted part on the inner peripheral side of the restricting portion 21 of the protruding portion 9, the lead wire 6 and the root portion 22 that straddle the fixed plane 13 are fastened by using a binding rope or tie Together, the lead 6 is fixed to the insulator 7.

本實施例的上述結構與第一實施例具有同樣的效果。The above-mentioned structure of this embodiment has the same effect as that of the first embodiment.

另外,由於引線6在電路板4與絕緣體7之間,因此,能夠抑制馬達的整體高度,實現馬達的小型化。In addition, since the lead wire 6 is between the circuit board 4 and the insulator 7, the overall height of the motor can be suppressed, and the size of the motor can be reduced.

由於固定平面13的靠近絕緣體外徑11的部分為固定引線6的平面、遠離絕緣體外徑11的部分向下向鐵芯2一側彎曲,因此,即使如圖9的背景技術所示,馬達的外框體從軸方向兩側覆蓋,也能夠減輕引線6在定子的高度方向上被壓迫而導致彎曲的負荷。Since the part of the fixing plane 13 close to the outer diameter 11 of the insulator is the plane where the lead 6 is fixed, and the part far away from the outer diameter 11 of the insulator is bent downward to the side of the iron core 2, therefore, even as shown in the background art of FIG. The outer frame is covered from both sides in the axial direction, and the load caused by bending of the lead wire 6 being pressed in the height direction of the stator can also be reduced.

通過上述結構,即使引線6受到拉扯或馬達運轉的振動等所產生的外力,即使外力通過絕緣體7傳遞到電路板4,由於內周側的突起部10b之間的距離比外周側的突起部10a之間的距離大,因此,能夠使電路板4更加穩固,從而保護電路板4上的電氣性連接部位。With the above structure, even if the lead wire 6 receives external force generated by pulling or vibration of the motor, even if the external force is transmitted to the circuit board 4 through the insulator 7, the distance between the protrusions 10b on the inner circumference side is longer than the distance between the protrusions 10a on the outer circumference side. The distance between them is large, so the circuit board 4 can be made more stable, thereby protecting the electrical connection parts on the circuit board 4.

上述結構的定子1a、1b可用於馬達中,而該馬達可適用於送風設備。The stators 1a, 1b of the above-mentioned structure can be used in a motor, and the motor can be applied to an air supply device.

至此,已經結合附圖對本實施例進行了詳細描述。依據以上描述,本領域技術人員應當對本公開定子、馬達及其送風裝置有了清楚的認識。本公開中引線可簡單地被固定並且能夠抵抗外部施加的力。So far, this embodiment has been described in detail with reference to the drawings.
