Description

この発明は、電動機の固定子に関するもので、特にリード線を配線するリード線配線部品に関するものである。また、その電動機の固定子を用いる電動機及び電動機の製造方法に関する。さらに、その電動機を搭載する空気調和機に関する。   The present invention relates to a stator of an electric motor, and more particularly to a lead wire wiring component for wiring lead wires. The present invention also relates to a motor using the stator of the motor and a method for manufacturing the motor. Furthermore, it is related with the air conditioner which mounts the electric motor.

従来、リード線を使用し外部と結線される固定子にモールドを施す電動機において、基板を廃止することにより直材費を低減させるために、固定子のリード端末を各所に有する固定子絶縁部を端部に形成した電動機の固定子と、外部の電源等に接続されるリード線と、固定子絶縁部に設けられ、固定子のリード端末とリード線とが接続されるリード接続手段と、電動機の固定子に組み付けられ、リード線の位置決めを行うリード線位置決め手段と、リード接続手段を通すためのリード接続手段取り付け用開口部とを有するリード固定板と、リード線をリード固定板に固定するリード線固定手段とを備えた電動機が提案されている（例えば、特許文献１参照）。   Conventionally, in a motor that uses a lead wire and molds the stator that is connected to the outside, in order to reduce the cost of direct materials by eliminating the substrate, the stator insulation part that has the lead terminals of the stator in various places An electric motor stator formed at the end, a lead wire connected to an external power source, etc., a lead connecting means provided in the stator insulation portion to connect the lead terminal of the stator and the lead wire, and the electric motor A lead wire positioning means for positioning the lead wire, a lead fixing plate having a lead connecting means mounting opening for passing the lead connecting means, and fixing the lead wire to the lead fixing plate. An electric motor provided with a lead wire fixing means has been proposed (see, for example, Patent Document 1).

また、電源リード線を直接コイルと結線する電動機の固定子において、回転子の回転検出センサーを低価格で簡単に取付けができるようにするために、固定子鉄心と、この固定子鉄心に絶縁部を介して施した巻線とを有する固定子と、この固定子に内装された回転子と、巻線に電力を供給するための電源リード線と、固定子に設けられ、電源リード線を保持する電源リード線保持手段と、回転子の回転を検出し、センサーリード線が接続された回転検出センサーを取付けた基板と、センサーリード線を押さえるリード線押さえ手段と、中仕切り部品と、を備え、センサーリード線はリード線押さえ手段と中仕切り部品とで、また、電源リード線は中仕切り部品と電源リード線保持手段とで挟み込まれて軸方向に２段に組立られる構成とした電動機の固定子が提案されている（例えば、特許文献２参照）。   In addition, in the stator of an electric motor in which the power supply lead wire is directly connected to the coil, in order to make it easy to install the rotation detection sensor of the rotor at a low cost, the stator core and an insulating part on the stator core A stator having a winding provided through the stator, a rotor embedded in the stator, a power supply lead wire for supplying power to the winding, and a stator provided to hold the power supply lead wire Power supply lead wire holding means, a substrate mounted with a rotation detection sensor to detect rotation of the rotor and connected to the sensor lead wire, a lead wire holding means for holding the sensor lead wire, and a partition part. The sensor lead wire is composed of the lead wire holding means and the partition part, and the power supply lead wire is sandwiched between the partition part and the power supply lead wire holding means and assembled in two stages in the axial direction. The stator of the machine has been proposed (e.g., see Patent Document 2).

さらに、直接外部と接続するリード線をリード線固定板に配置して、固定子のコイル端末と結線された端子と結線される電動機の固定子について、被覆が剥かれたリード線先端を位置決めすることにより、組立て性の向上による電動機の品質の向上を図るために、固定子鉄心に形成された固定子絶縁部にコイルを巻き回し、このコイルに電源を供給するために外部と接続されるリード線とコイルを固定子絶縁部に設けられた端子を介して結線し、リード線をリード線固定板に固定したものにおいて、被覆を剥いたリード線先端を保持してリード線先端の位置決めをするリード線先端保持部をリード線固定板に設けた電動機の固定子が提案されている（例えば、特許文献３参照）。   Furthermore, the lead wire directly connected to the outside is arranged on the lead wire fixing plate, and the tip of the lead wire from which the coating has been peeled is positioned with respect to the stator of the motor connected to the terminal connected to the coil terminal of the stator. Therefore, in order to improve the quality of the motor by improving the assemblability, the coil is wound around the stator insulating portion formed on the stator core, and the lead connected to the outside for supplying power to the coil Wires and coils are connected via terminals provided on the stator insulation, and the lead wires are fixed to the lead wire fixing plate. An electric motor stator in which a lead wire tip holding portion is provided on a lead wire fixing plate has been proposed (see, for example, Patent Document 3).

本実施の形態の電動機の固定子１００は、例えば、電動機がブラシレスＤＣモータの固定子である。電動機の用途は、例えば、送風機用電動機等である。電動機として、固定子のスロット数（ティース数）が９で、回転子の極数が８極ものを例に説明する。当然ではあるが、この仕様の電動機に限定されるものではない。スロット数、極数は問わない。   In the electric motor stator 100 of the present embodiment, for example, the electric motor is a stator of a brushless DC motor. The use of the electric motor is, for example, a blower motor. As an electric motor, an example in which the number of stator slots (number of teeth) is 9 and the number of rotor poles is 8 will be described. Of course, the motor is not limited to this specification. The number of slots and the number of poles do not matter.

図１、図２に示すように、電動機の固定子１００は、固定子組立５０と、リード線配線部品組立２００とを備える。   As shown in FIGS. 1 and 2, the stator 100 of the electric motor includes a stator assembly 50 and a lead wire wiring component assembly 200.

先ず、図３により、固定子組立５０の構成を説明する。図３に示すように、固定子組立５０は、固定子鉄心５１と、固定子鉄心５１のティースに絶縁部５２を介して巻回されるコイル５４とを備える。   First, the configuration of the stator assembly 50 will be described with reference to FIG. As shown in FIG. 3, the stator assembly 50 includes a stator core 51 and a coil 54 wound around the teeth of the stator core 51 via an insulating portion 52.

電動機の固定子１００は、インナーロータ形の電動機の固定子である。図示しない回転子（ロータ）が、電動機の固定子１００の内部に挿入されて回転する。   The electric motor stator 100 is an inner rotor type electric motor stator. A rotor (rotor) (not shown) is inserted into the stator 100 of the electric motor and rotates.

固定子鉄心５１は、電磁鋼板が帯状に所定の形状に打ち抜かれ、所定の枚数をかしめ（一般的である）、溶接、接着等で積層されて形成される。本実施の形態の固定子鉄心５１は、コアバック５６から略直角に延びる９個のティース５７を有する。   The stator core 51 is formed by punching a magnetic steel sheet into a predetermined shape in a band shape, and laminating a predetermined number of sheets (generally), welding, adhesion, or the like. The stator core 51 of the present embodiment has nine teeth 57 extending from the core back 56 at a substantially right angle.

巻線が完了して固定子鉄心５１を略円筒形に曲げた固定子組立５０では、９個のティース５７は円筒形状のコアバック５６の内周から中心に向かって放射状に延びる。図３では、ティース５７の先端部（図示しない回転子に対向する部分）が見えているが、その他の部分は、コイル５４と絶縁部５２とに隠れて見えていない。但し、ティース５７の数は、９個に限定されるものではない。   In the stator assembly 50 in which the winding is completed and the stator core 51 is bent into a substantially cylindrical shape, the nine teeth 57 extend radially from the inner periphery of the cylindrical core back 56 toward the center. In FIG. 3, the tip portion of the tooth 57 (the portion facing the rotor (not shown)) is visible, but the other portion is hidden behind the coil 54 and the insulating portion 52 and is not visible. However, the number of teeth 57 is not limited to nine.

帯状の固定子鉄心５１の９個のティース５７に、例えば、ＰＢＴ（ポリブチレンテレフタレート）等の熱可塑性樹脂を一体に成形して絶縁部５２が形成される。但し、熱可塑性樹脂で成形した絶縁部５２をティース５７に組付けるようにしてもよい。   For example, a thermoplastic resin such as PBT (polybutylene terephthalate) is integrally formed on the nine teeth 57 of the belt-shaped stator core 51 to form the insulating portion 52. However, you may make it assemble the insulation part 52 shape | molded with the thermoplastic resin to the teeth 57. FIG.

各ティース５７は、図示しない回転子に対向するティース５７の先端部を除いて、絶縁部５２で覆われる。回転子に対向するティース５７の先端部と回転子の外周面との間は、所定の径方向寸法の空隙となる。電動機の効率は、空隙の径方向寸法と密接な関係があり、空隙の径方向寸法は極力小さい方が好ましい。そのため、ティース５７の先端部は絶縁部５２で覆わずに露出させる。   Each tooth 57 is covered with an insulating portion 52 except for a tip portion of the tooth 57 facing a rotor (not shown). A gap having a predetermined radial dimension is formed between the tip of the teeth 57 facing the rotor and the outer peripheral surface of the rotor. The efficiency of the electric motor is closely related to the radial dimension of the gap, and it is preferable that the radial dimension of the gap is as small as possible. Therefore, the tip portion of the teeth 57 is exposed without being covered with the insulating portion 52.

ティース５７に絶縁部５２を施した後、帯状の固定子鉄心５１を逆曲げして巻線しやすい形状にする。帯状の固定子鉄心５１を逆曲げすると、コアバック５６が内側になり、ティース５７がコアバック５６の外側に位置する。そして、この状態は、隣接するティース５７の先端の間が帯状のときよりも広くなるので、巻線がしやすくなる。   After the insulating portion 52 is applied to the teeth 57, the strip-shaped stator core 51 is reversely bent so as to be easily wound. When the belt-shaped stator iron core 51 is reversely bent, the core back 56 is located inside, and the teeth 57 are located outside the core back 56. In this state, the gap between the tips of the adjacent teeth 57 is wider than when the band 57 is formed, so that the winding is easy.

固定子鉄心５１を逆曲げした状態で、マグネットワイヤーを各ティース５７に巻きつけてコイル５４を形成する。   In a state where the stator iron core 51 is reversely bent, a coil 54 is formed by winding a magnet wire around each tooth 57.

例えば、コイル５４は、三相の巻線であり、Ｙ結線（三相各相をその一端の中性点で接続する結線で、星形結線、スター結線とも呼ばれる）の三相巻線を形成する。   For example, the coil 54 is a three-phase winding, and forms a three-phase winding of a Y connection (a connection connecting each phase of the three phases at a neutral point at one end thereof, also called a star connection or a star connection). To do.

（２）第２の電源リード線７０−２が、図１５の右端に見える位置ずれ防止突起１７ａ付近まで来ると、第３の電源リード線７０−３と重なるため、先に第２の電源リード線７０−２を位置ずれ防止突起１７ａの内部に納め、その後で第３の電源リード線７０−３を第２の電源リード線７０−２の外側に配置する。
（３）図１５の右端に見える位置ずれ防止突起１７ａと第３の折り返し部２６との間においては、順序が逆になる。第２の電源リード線７０−２は、内周壁１７から離しておき、先に第３の電源リード線７０−３を第３の折り返し部２６で略直角に折り返して、突起２８と側壁２９との間の第３の電源リード線保持部２７−３に保持されて電源リード線用溝３２から外部に引き出す。
（４）その後、第２の電源リード線７０−２を第３の電源リード線７０−３の内側に押し込み、口出し部１１の第２の折り返し部２４で略直角に折り返し、二つの突起２８の間の第２の電源リード線保持部２７−２に保持されて電源リード線用溝３２から外部に引き出す。 The procedure for assembling the second power supply lead wire 70-2 and the third power supply lead wire 70-3 to the lead-out portion 11 is as follows.
(1) The second power supply lead wire 70-2 is routed from the covered terminal holding portion 13 farthest from the lead-out portion 11 to the lead-out portion 11 along the inner peripheral wall 17, but the third power supply lead wire 70-3 There is no particular problem until it overlaps.
(2) When the second power supply lead wire 70-2 comes to the position near the misalignment prevention protrusion 17a visible at the right end of FIG. 15, it overlaps with the third power supply lead wire 70-3. The line 70-2 is placed inside the misalignment prevention protrusion 17a, and then the third power supply lead 70-3 is disposed outside the second power supply lead 70-2.
(3) The order is reversed between the misalignment prevention projection 17a visible at the right end of FIG. The second power supply lead wire 70-2 is separated from the inner peripheral wall 17, and the third power supply lead wire 70-3 is first folded at a substantially right angle by the third turn-up portion 26, and the projection 28, the side wall 29, Is held by the third power supply lead wire holding portion 27-3 and is drawn out from the power supply lead wire groove 32.
(4) Thereafter, the second power supply lead wire 70-2 is pushed into the third power supply lead wire 70-3, folded back at a substantially right angle by the second folded back portion 24 of the lead-out portion 11, and the two projections 28 It is held by the second power supply lead wire holding portion 27-2 and is pulled out from the power supply lead wire groove 32.

図８において、第１の電源リード線７０−１は、口出し部１１から口出し部１１の左側の被覆端末保持部１３へ時計方向に引き回される。   In FIG. 8, the first power supply lead wire 70-1 is drawn clockwise from the lead-out portion 11 to the covered terminal holding portion 13 on the left side of the lead-out portion 11.

口出し部１１の左側の被覆端末保持部１３から内周壁１７の外側に沿って口出し部１１まで引き回され、第１の折り返し部２５で略直角に折り返されて、突起２８と側壁２９との間の第１の電源リード線保持部２７−１に保持されて電源リード線用溝３２から外部に引き出される。   From the coated terminal holding part 13 on the left side of the lead part 11, the lead part 11 is routed along the outside of the inner peripheral wall 17 to the lead part 11, and is folded at a substantially right angle by the first folding part 25. Is held by the first power supply lead wire holding portion 27-1 and pulled out from the power supply lead wire groove 32.

第１の折り返し部２５も、上部に位置ずれ防止突起２５ａを有する。   The first folded portion 25 also has a misalignment prevention protrusion 25a on the top.

電源リード線７０（３本）の口出し部１１への仮固定が完了したら、電源リード線保持部品７１を一対の第２の係り止め部２２に係り止めて電源リード線７０を固定する。電源リード線をリード線配線部品に固定した後に、基板をリード線配線部品の一対の組付け足８１ａと一対の組付け足８１ｂに組付け、センサーリード線に備えたボードイン形コネクタ９０を基板に半田付けして接合する。   When the temporary fixing of the power supply lead wires 70 (three) to the lead-out portion 11 is completed, the power supply lead wire holding component 71 is locked to the pair of second locking portions 22 to fix the power supply lead wire 70. After fixing the power supply lead wire to the lead wire wiring component, the board is assembled to the pair of assembly feet 81a and the pair of assembly feet 81b of the lead wire wiring component, and the board-in connector 90 provided for the sensor lead wire is installed on the substrate. Solder to and join.

センサーリード線６０の配線は、中央の３本が保持突起２３の間に軽く保持される（図１４参照）。また、両端の２本のセンサーリード線６０は、保持突起２３と、電源リード線保持部品７１の突起７１ｂ（図１８参照）の内側との間に軽く保持される。電源リード線保持部品の突起７１ｂでセンサーリード線を軽く保持する構造とすることで、電源リード線保持部品を小さくすることが出来るため、コストの低減が図れる。
センサーリード線は、センサーリード線保持部品６１を一対の第１の係り止め部２１に係り止めて固定する。 The three sensor lead wires 60 are lightly held between the holding projections 23 (see FIG. 14). Further, the two sensor lead wires 60 at both ends are lightly held between the holding projection 23 and the inside of the projection 71b (see FIG. 18) of the power supply lead wire holding component 71. By adopting a structure in which the sensor lead wire is lightly held by the projection 71b of the power supply lead wire holding component, the power supply lead wire holding component can be made small, so that the cost can be reduced.
The sensor lead wire engages and fixes the sensor lead wire holding component 61 to the pair of first anchor portions 21.

図１８に示すように、電源リード線保持部品７１は、既に述べた突起７１ｂ（口出し方向に略直角方向に形成される）を有する一対の足７１ａ（口出し部１１への設置面７１ｆより直角に延びる）以外に、口出し部１１へ組付けた状態でリード線配線部品１０の中心側（内側）に延びる一対のリブ７１ｃと、この一対のリブ７１ｃを連結する連結部７１ｄとを備える。   As shown in FIG. 18, the power supply lead wire holding component 71 has a pair of legs 71 a (which are formed in a direction substantially perpendicular to the lead-out direction) described above at a right angle from the installation surface 71 f on the lead-out portion 11. In addition to a pair of ribs 71c extending to the center side (inner side) of the lead wire wiring component 10 in a state assembled to the lead portion 11, and a connecting portion 71d for connecting the pair of ribs 71c.

図７に示すように、電源リード線保持部品７１を口出し部１１へ組付けた状態では、リブ７１ｃがリード線配線部品を押えるので、口出し部１１の外側端部における電源リード線７０の軸方向に開くガタを減らすことができる。   As shown in FIG. 7, in the state where the power supply lead wire holding component 71 is assembled to the lead portion 11, the rib 71 c presses the lead wire wiring component, so the axial direction of the power lead wire 70 at the outer end portion of the lead portion 11 Can reduce the amount of backlash.

図１７に示すように、センサーリード線保持部品６１は、センサーリード線６０を納める溝６１ｂを有する。   As shown in FIG. 17, the sensor lead wire holding component 61 has a groove 61 b for receiving the sensor lead wire 60.

図１８に示すように、電源リード線保持部品７１は、電源リード線７０を納める溝７１ｅを有する。   As shown in FIG. 18, the power supply lead wire holding component 71 has a groove 71 e for receiving the power supply lead wire 70.

以上でリード線配線部品組立２００の組立が完了する。尚、口出し部１１から外部へ引き出されたセンサーリード線６０（５本）及び電源リード線７０（３本）の処理については、本実施の形態の主要な特徴に関係しないので、説明は省く。   Thus, the assembly of the lead wire wiring component assembly 200 is completed. Note that the processing of the sensor lead wires 60 (5 wires) and the power supply lead wires 70 (3 wires) drawn out from the lead-out portion 11 is not related to the main features of the present embodiment, and will not be described.

次に、リード線配線部品組立２００の固定子組立５０への組付けについて説明する。   Next, assembly of the lead wire wiring component assembly 200 to the stator assembly 50 will be described.

図１、図２に示すように、リード線配線部品１０の取付足１２の穴１２ａに固定子組立５０の絶縁部５２のピン５３を挿入して、リード線配線部品組立２００を固定子組立５０へ組付ける。   As shown in FIGS. 1 and 2, the pin 53 of the insulating portion 52 of the stator assembly 50 is inserted into the hole 12 a of the mounting leg 12 of the lead wire wiring component 10, and the lead wire wiring component assembly 200 is fixed to the stator assembly 50. Assemble.

このとき、リード線配線部品１０の取付足１２が絶縁部５２の設置面５２ａに当接して、リード線配線部品１０の軸方向の位置決めがなされる。また、絶縁部５２のピン５３が、リード線配線部品１０の取付足１２の穴１２ａに挿入されることで、リード線配線部品１０の回転方向の位置決めがなされる。   At this time, the mounting legs 12 of the lead wire wiring component 10 abut on the installation surface 52a of the insulating portion 52, and the lead wire wiring component 10 is positioned in the axial direction. Further, the pin 53 of the insulating portion 52 is inserted into the hole 12 a of the mounting leg 12 of the lead wire wiring component 10, whereby the lead wire wiring component 10 is positioned in the rotational direction.

リード線配線部品１０の取付足１２の穴１２ａに固定子組立５０の絶縁部５２のピン５３を挿入後、穴１２ａから突出するピン５３を、熱溶着、超音波溶着等で固定する（図１９）。   After inserting the pin 53 of the insulating portion 52 of the stator assembly 50 into the hole 12a of the mounting leg 12 of the lead wire wiring component 10, the pin 53 protruding from the hole 12a is fixed by heat welding, ultrasonic welding, or the like (FIG. 19). ).

固定子組立５０にリード線配線部品１０が組付けられた後に、電源リード線７０の芯線７０ａと端子５５とをスポット溶接して、電源リード線７０と端子５５とを接続する（図２０）。   After the lead wire wiring component 10 is assembled to the stator assembly 50, the core wire 70a of the power supply lead wire 70 and the terminal 55 are spot welded to connect the power supply lead wire 70 and the terminal 55 (FIG. 20).

このとき、端子５５と芯線７０ａとを挟み込む電極（リード線配線部品１０の内側に配置される電極）の空間確保ために、リード線配線部品１０に電極逃がし用の凹部１４（図１、図２、図６、図９）を設ける。   At this time, in order to secure a space for an electrode (electrode disposed inside the lead wire wiring component 10) sandwiching the terminal 55 and the core wire 70a, the lead wire wiring component 10 has an electrode escape recess 14 (FIGS. 1 and 2). 6 and 9).

また、電極逃がし用の凹部１４を設けることで、電源リード線７０はリード線配線部品１０のリード線配線面１６ａ（図１０）よりもさらに固定子組立５０側に引回され（固定子組立５０側に張り出す）、且つ位置ずれ防止突起１７ａを電極逃がし用の凹部１４（電源リード線７０が裏側を通る凹部１４、例えば図８の口出し部１１の右側の凹部１４）の両側に設けることで、電源リード線７０は凹部１４の裏側と、凹部１４の両側の位置ずれ防止突起１７ａとの間に挟まれて強固に固定されて軸方向の位置決めがなされる。   Further, by providing the electrode escape recess 14, the power supply lead wire 70 is further routed to the stator assembly 50 side than the lead wire wiring surface 16 a (FIG. 10) of the lead wire wiring component 10 (stator assembly 50). The projections 17a are provided on both sides of the electrode escape recess 14 (the recess 14 through which the power supply lead wire 70 passes through the back side, for example, the recess 14 on the right side of the lead 11 in FIG. 8). The power lead 70 is sandwiched between the back side of the recess 14 and the misalignment prevention protrusions 17a on both sides of the recess 14 and is firmly fixed to be positioned in the axial direction.

以上のように、電源リード線７０をリード線配線部品１０の固定子組立５０側の面に引き回し、センサーリード線６０をリード線配線部品１０の反固定子組立５０側の面に引き回すので、リード線配線部品組立２００の組立が容易となりコストの低減が図れる。また、リード線配線部品組立２００の組立が容易になることに伴い品質の向上が図れる。   As described above, the power supply lead wire 70 is routed to the surface of the lead wire wiring component 10 on the stator assembly 50 side, and the sensor lead wire 60 is routed to the surface of the lead wire wiring component 10 on the side opposite to the stator assembly 50. Assembly of the line wiring component assembly 200 is facilitated, and costs can be reduced. Further, quality can be improved as the assembly of the lead wire wiring component assembly 200 becomes easier.

また、電源リード線７０を位置ずれ防止突起１７ａで保持して軸方向の位置ずれを防止することで、品質の向上が図れる。   Further, the power lead 70 is held by the misalignment prevention protrusion 17a to prevent the misalignment in the axial direction, so that the quality can be improved.

また、リード線配線部品１０の口出し部１１に、第１の係り止め部２１及び第２の係り止め部２２を備えることで、電源リード線７０を電源リード線保持部品７１で保持し、センサーリード線６０をセンサーリード線保持部品６１で保持するので、電源リード線７０及びセンサーリード線６０をリード線配線部品１０に強固に組み付けが可能となり、組立て状態の信頼性向上に伴う品質の向上が図れる。   Further, the lead wire wiring component 10 includes the first locking portion 21 and the second locking portion 22 in the lead portion 11 so that the power lead 70 is held by the power lead holding component 71 and the sensor lead. Since the wire 60 is held by the sensor lead wire holding component 61, the power supply lead wire 70 and the sensor lead wire 60 can be firmly assembled to the lead wire wiring component 10, and the quality can be improved as the reliability of the assembled state is improved. .

さらに、電源リード線保持部品７１の足７１ａの突起７１ｂをセンサーリード線６０の保持にも使用することで、組立てが容易となりコストの低減が図れる。また、組立が容易になることに伴い品質の向上が図れる。   Furthermore, by using the protrusion 71b of the foot 71a of the power supply lead wire holding component 71 also for holding the sensor lead wire 60, the assembly can be facilitated and the cost can be reduced. Further, the quality can be improved as the assembly becomes easier.

図２１乃至図２８により芯線保持部１５について詳細に説明する。   The core wire holding portion 15 will be described in detail with reference to FIGS.

図２１に示すように、リード線配線部品１０の被覆端末保持部１３から引き出される電源リード線７０の芯線７０ａを保持する芯線保持部１５は、リード線配線部品１０の環状板部１６の外周側に形成されている。   As shown in FIG. 21, the core wire holding portion 15 that holds the core wire 70 a of the power supply lead wire 70 drawn from the covered terminal holding portion 13 of the lead wire wiring component 10 is the outer peripheral side of the annular plate portion 16 of the lead wire wiring component 10. Is formed.

リード線配線部品１０の被覆端末保持部１３から引き出される電源リード線７０の芯線７０ａは、リード線配線部品１０の環状板部１６の外周の略接線方向に引き回されて芯線保持部１５に至る。   The core wire 70 a of the power supply lead wire 70 drawn out from the covered terminal holding portion 13 of the lead wire wiring component 10 is drawn in the substantially tangential direction of the outer periphery of the annular plate portion 16 of the lead wire wiring component 10 to reach the core wire holding portion 15. .

芯線保持部１５は、少なくとも以下に示す要素を備える。
（１）環状板部１６から径方向外側に延びて形成される芯線位置決め部４０。芯線位置決め部４０は、環状板部１６から径方向外側に突出する位置決め部本体４１と、位置決め部本体４１の外周側先端に設けられる突起４２（第１の突起）と、位置決め部本体４１の周方向端部（被覆端末保持部１３の反対側の端部）に形成される張り出し部４３とを備える。軸方向に見た場合、張り出し部４３は突起４２よりも外側にあり、突起４２と張り出し部４３との間に芯線７０ａが保持される。
（２）芯線位置決め部４０の内周側端部近傍で、環状板部１６の外周付近に形成される円柱部４４。円柱部４４は、環状板部１６に対して略直角に軸方向外側に向かって立設している。円柱部４４は、外周部４４−１と、内周部４４−２とに分かれている。円柱部４４の外周部４４−１と内周部４４−２との間に、隙間４７（空間）が形成されている。さらに、内周部４４−２には、縦断面が略三角形で、環状板部１６の接線方向から見て、外周部４４−１側に突出し下側に芯線７０ａを係り止める空間を形成する係り止め部４４ａが設けられる。
（３）円柱部４４の外周部４４−１の固定子組立５０側端部に、被覆端末保持部１３の反対側に周方向に延びる突起４５（第２の突起）。突起４５は、芯線７０ａを円柱部４４を引き回すときに、芯線７０ａが固定子組立５０側に位置ずれしないようにするために設ける。
（４）円柱部４４の外周部４４−１の固定子組立５０側端部から被覆端末保持部１３から延び、位置決め部４０の位置決め部本体４１に連結する周壁４８。
（５）周壁４８の円柱部４４の反対側の周方向端部に設けられ、径方向外側に突出する突起４６（第３の突起）。 The core wire holding part 15 includes at least the following elements.
(1) A core wire positioning portion 40 formed to extend radially outward from the annular plate portion 16. The core wire positioning portion 40 includes a positioning portion main body 41 that protrudes radially outward from the annular plate portion 16, a protrusion 42 (first protrusion) provided at the outer peripheral end of the positioning portion main body 41, and a periphery of the positioning portion main body 41. And a projecting portion 43 formed at a direction end portion (an end portion on the opposite side of the covering terminal holding portion 13). When viewed in the axial direction, the overhanging portion 43 is outside the protrusion 42, and the core wire 70 a is held between the protrusion 42 and the overhanging portion 43.
(2) A cylindrical portion 44 formed in the vicinity of the inner peripheral side end of the core wire positioning portion 40 and in the vicinity of the outer periphery of the annular plate portion 16. The cylindrical portion 44 is erected outward in the axial direction at a substantially right angle to the annular plate portion 16. The cylindrical portion 44 is divided into an outer peripheral portion 44-1 and an inner peripheral portion 44-2. A gap 47 (space) is formed between the outer peripheral portion 44-1 and the inner peripheral portion 44-2 of the cylindrical portion 44. Further, the inner peripheral portion 44-2 has a substantially triangular vertical cross section, and when viewed from the tangential direction of the annular plate portion 16, a space that protrudes toward the outer peripheral portion 44-1 and holds the core wire 70a on the lower side is formed. A stop 44a is provided.
(3) A protrusion 45 (second protrusion) extending in the circumferential direction on the opposite side of the covered terminal holding portion 13 at the end on the stator assembly 50 side of the outer peripheral portion 44-1 of the cylindrical portion 44. The protrusion 45 is provided in order to prevent the core wire 70 a from being displaced toward the stator assembly 50 when the core wire 70 a is routed around the cylindrical portion 44.
(4) A peripheral wall 48 that extends from the coated terminal holding portion 13 from the end on the stator assembly 50 side of the outer peripheral portion 44-1 of the cylindrical portion 44 and is connected to the positioning portion main body 41 of the positioning portion 40.
(5) A projection 46 (third projection) provided at the circumferential end of the peripheral wall 48 on the opposite side of the cylindrical portion 44 and protruding radially outward.

次に、芯線７０ａを芯線保持部１５に係り止めする手順を図２７を参照しながら説明する。尚、図２７における実線矢印は表側を、破線矢印は裏側をとおることを示す。
（１）被覆端末保持部１３から引き出された芯線７０ａを、芯線位置決め部４０の突起４２の軸方向外側（固定子組立５０の反対側）の面に引き回す（図２７のａ）。
（２）位置決め部本体４１の角で径方向内側に折り返す。
（３）芯線位置決め部４０の張り出し部４３の軸方向内側（固定子組立５０側）を引き回す（図２７のｂ）。この時点で、芯線７０ａは、突起４２と張り出し部４３とにより、軸方向の位置ずれが抑制される。
（４）続いて円柱部４４の外周部４４−１と内周部４４−２との間の隙間４７に、突起４５側から芯線７０ａを挿入する。そして、円柱部４４の右端付近まで引き回す。結果的に図２７の矢印ｃのように、芯線７０ａが周壁４８裏側をとおったことになる。
（５）円柱部４４の内周部４４−２の外側に沿って、芯線７０ａを引き回す（図２７のｄ）。ここで、芯線がリード線配線部品の端面より凹となる溝を引き回すことで、芯線の引回し部への接触を極力避けることが出来るため、組立の品質が向上する。
（６）さらに、円柱部４４の内周部４４−２の外側、隙間４７をとおり、突起４５の表側（反固定子組立５０側）まで芯線７０ａを引き回す（図２７のｅ）。この状態では、円柱部４４の外周部４４−１の外側にかかりはじめる。
（７）芯線７０ａは、円柱部４４の外周部４４−１の外側に沿い、さらに周壁４８の外側の面に沿って突起４６方向に向かう（図２７のｆ）。
（８）芯線７０ａは、突起４６の裏側（固定子組立５０側）をとおり、突起４６の突起４５と反対側の端部で内側（リード線配線部品１０の中心側）に折り返す（図２７のｇ）。図２７のｅで、芯線７０ａは突起４５の表側（反固定子組立５０側）をとおり、図２７のｇで突起４６の裏側（固定子組立５０側）をとおるので軸方向の位置ずれが抑制される。
（９）芯線７０ａは、周壁４８の角に沿って引き回される（図２７のｈ）。
（１０）その後芯線７０ａは、周壁４８の内側の面に沿って引き回され、最後に円柱部４４の係り止め部４４ａに係り止めされる（図２７のｉ）。図２７のｄ〜ｆに芯線７０ａを引き回すことにより、隙間４７で分割された円柱部４４は、隙間４７が小さくなり、締め付けられる。従って、図２８の最終的な状態にするには、芯線７０ａに力を加えて、隙間４７をこじ開けて係り止め部４４ａの下の空間に芯線７０ａを押しこむことで、強固に芯線７０ａは係り止め部４４ａの下の空間に係り止められる。係り止め部４４ａの下の空間は、係り止め部４４ａの底面４４ａ−１と、外周部４４−１及び内周部４４−２の内周面と、既に引き回されている芯線７０ａで構成される。 Next, a procedure for engaging the core wire 70a with the core wire holding portion 15 will be described with reference to FIG. In FIG. 27, a solid line arrow indicates that the front side is shown, and a broken line arrow indicates that the back side is provided.
(1) The core wire 70a pulled out from the covering terminal holding portion 13 is drawn around the surface on the axially outer side (opposite side of the stator assembly 50) of the protrusion 42 of the core wire positioning portion 40 (a in FIG. 27).
(2) Fold it inward in the radial direction at the corner of the positioning portion main body 41.
(3) The axial direction inner side (stator assembly 50 side) of the overhanging portion 43 of the core wire positioning portion 40 is routed (b in FIG. 27). At this point, the axial position of the core wire 70a is suppressed by the protrusion 42 and the protruding portion 43.
(4) Subsequently, the core wire 70a is inserted into the gap 47 between the outer peripheral portion 44-1 and the inner peripheral portion 44-2 of the cylindrical portion 44 from the protrusion 45 side. Then, it is routed to the vicinity of the right end of the cylindrical portion 44. As a result, the core wire 70a has passed through the back side of the peripheral wall 48 as shown by an arrow c in FIG.
(5) The core wire 70a is routed along the outside of the inner peripheral portion 44-2 of the cylindrical portion 44 (d in FIG. 27). Here, by drawing a groove in which the core wire is recessed from the end face of the lead wire wiring component, contact with the lead portion of the core wire can be avoided as much as possible, so that the assembly quality is improved.
(6) Further, the core wire 70a is routed through the outer side of the inner peripheral portion 44-2 of the cylindrical portion 44 and the gap 47 to the front side of the protrusion 45 (on the anti-stator assembly 50 side) (e in FIG. 27). In this state, it starts to the outside of the outer peripheral portion 44-1 of the cylindrical portion 44.
(7) The core wire 70a is directed toward the protrusion 46 along the outer surface of the outer peripheral portion 44-1 of the cylindrical portion 44 and further along the outer surface of the peripheral wall 48 (f in FIG. 27).
(8) The core wire 70a passes through the back side (stator assembly 50 side) of the protrusion 46 and is folded back inside (center side of the lead wire wiring component 10) at the end opposite to the protrusion 45 of the protrusion 46 (in FIG. 27). g). In FIG. 27e, the core wire 70a passes the front side (anti-stator assembly 50 side) of the projection 45, and passes the back side (stator assembly 50 side) of the projection 46 in FIG. Is done.
(9) The core wire 70a is routed along the corner of the peripheral wall 48 (h in FIG. 27).
(10) Thereafter, the core wire 70a is routed along the inner surface of the peripheral wall 48, and finally locked to the locking portion 44a of the cylindrical portion 44 (i in FIG. 27). By pulling the core wire 70a around d to f in FIG. 27, the cylindrical portion 44 divided by the gap 47 is tightened with the gap 47 becoming smaller. Therefore, in order to obtain the final state of FIG. 28, the core wire 70a is firmly engaged by applying force to the core wire 70a to pry the gap 47 and push the core wire 70a into the space below the locking portion 44a. It is locked in the space below the stopper 44a. The space below the locking portion 44a is composed of the bottom surface 44a-1 of the locking portion 44a, the inner peripheral surfaces of the outer peripheral portion 44-1 and the inner peripheral portion 44-2, and the core wire 70a that has already been routed.
