Description

本願は、回転電機に関するものである。 The present application relates to a rotary electric machine.

搭載スペースに制限のある自動車用の回転電機および発電機において、小型、高出力が求められている。小型化、高出力化するに当たり、各巻線に大きな電流を分配する手法として特許文献１のように断面矩形の結線板を円環状に配置し、各巻線と接続する手法が用いられている。 Small size and high output are required for rotary electric machines and generators for automobiles with limited mounting space. In order to reduce the size and increase the output, a method of arranging a connection plate having a rectangular cross section in an annular shape and connecting to each winding is used as a method of distributing a large current to each winding.

このような結線板を固定子に固定する手法として、特許文献１では、結線板に返しを構成し、インシュレーター（ボビン相当）に嵌合させる手法がとられている。また、特許文献２では、結線板をインサートモールドし、固定している。 As a method of fixing such a connection plate to a stator, Patent Document 1 adopts a method of forming a barb on the connection plate and fitting it to an insulator (corresponding to a bobbin). Further, in Patent Document 2, the connection plate is insert-molded and fixed.

特開２００８−３１２２７６号公報Japanese Unexamined Patent Publication No. 2008-31276 特開２０１０−１４１９５３号公報Japanese Unexamined Patent Publication No. 2010-141953

しかしながら、車載用のように高い振動が発生する回転電機においては、特許文献１のような構造では、振動に耐えられず、結線板が脱落することがある。また、特許文献２のようなインサートモールドは、製造コストが高くつくといった課題があった。 However, in a rotary electric machine that generates high vibration such as for automobiles, the structure as in Patent Document 1 cannot withstand the vibration and the connection plate may fall off. Further, the insert mold as in Patent Document 2 has a problem that the manufacturing cost is high.

本願は、上記に鑑みてなされたものであって、高い振動があっても結線板が脱落することのない強固な固定を実現するとともに、製造コストが安価となる回転電機を提供することを目的とする。 The present application has been made in view of the above, and an object of the present application is to provide a rotary electric machine which realizes a strong fixing in which the connection plate does not fall off even if there is a high vibration and the manufacturing cost is low. And.

本願に開示される回転電機は、鉄心の端部に設けられ容器状の溝部を有するボビンと、
前記ボビンに導体線を巻回したコイルと、回転軸の周りに配置された複数の前記コイルに電流を分配すると共に、前記容器状の溝部に溜められた接着剤内に埋没して突出部が固着された結線板と、を備え、前記結線板は、円環状の形態を有し、前記突出部が複数の前記コイルに対応して設けられており、前記容器状の溝部は、周方向に設けられ前記結線板を径方向両側から支える支持壁と、前記支持壁の周方向両端に設けられた隔壁とで形成されているものである。

The rotary electric machine disclosed in the present application includes a bobbin provided at the end of an iron core and having a container-shaped groove.
The current is distributed to the coil in which the conductor wire is wound around the bobbin and the plurality of coils arranged around the rotation axis, and the protruding portion is buried in the adhesive stored in the container-shaped groove. A fixed connection plate is provided, the connection plate has an annular shape, the protrusions are provided corresponding to a plurality of the coils, and the container-shaped groove portion is provided in the circumferential direction. It is formed by a support wall provided and supporting the connection plate from both sides in the radial direction, and partition walls provided at both ends in the circumferential direction of the support wall .

本願によれば、導体線を巻回されることによってコイルと一体になったボビンに容器状の溝部を有し、その中の接着剤内に結線板の突出部が固着されているので、回転軸の周方向に配置された複数のコイルに対応して結線板を固定することができる。 According to the present application, the bobbin integrated with the coil by winding the conductor wire has a container-shaped groove, and the protruding portion of the connection plate is fixed in the adhesive in the bobbin, so that the bobbin rotates. The connection plate can be fixed corresponding to a plurality of coils arranged in the circumferential direction of the shaft.

また、ボビンの容器状の溝部に接着剤を使用するだけなので、回転電機の回転軸の周方向全体に接着剤を使用することがなく、製造コストを少なくすることが可能である。 Further, since the adhesive is only used for the container-shaped groove of the bobbin, the adhesive is not used in the entire circumferential direction of the rotating shaft of the rotary electric machine, and the manufacturing cost can be reduced.

FIG. 1 is a schematic view showing a cross section of a rotary electric machine according to a first embodiment of the present application. In FIG. 1, the rotary electric machine 100 includes a housing 210 composed of a bottomed cylindrical frame 211 and an end plate 212 that closes an opening of the frame 211, and an armature fixed to the cylindrical portion of the frame 211 in an inwardly fitted state. The 300, the bottom of the frame 211, and the end plate 212 are rotatably supported via a bearing 201, and are provided with a rotor 400 arranged on the inner peripheral side of the armature 300.

電機子３００は、磁束を発生する複数のコイル３１０と、複数のコイル３１０に電流を分配する結線板３２０、磁束を流す鉄心３３０で構成されており、コイル３１０と鉄心３３０はボビン３１１で電気的に絶縁されている。 The armature 300 is composed of a plurality of coils 310 that generate magnetic flux, a connection plate 320 that distributes current to the plurality of coils 310, and an iron core 330 that allows magnetic flux to flow. The coil 310 and the iron core 330 are electrically operated by a bobbin 311. Insulated in.

回転子４００は、例えば永久磁石型回転子であって、回転軸４０１にその軸心位置が挿着された円筒状の回転子鉄心４０２と、この回転子鉄心４０２の外周面側に埋設されて周方向に所定のピッチで配列されて磁極を構成する永久磁石４０３とを備えている。なお、回転子４００は、このような永久磁石型回転子に限定されず、いわゆるかご形回転子、巻線形回転子などを用いてもよい。 The rotor 400 is, for example, a permanent magnet type rotor, and is embedded in a cylindrical rotor core 402 in which the axial center position is inserted into the rotating shaft 401 and on the outer peripheral surface side of the rotor core 402. It includes permanent magnets 403 that are arranged at a predetermined pitch in the circumferential direction to form magnetic poles. The rotor 400 is not limited to such a permanent magnet type rotor, and a so-called cage type rotor, winding type rotor, or the like may be used.

図２は実施の形態１に係る回転電機の電機子３００の全体を示す斜視図である。鉄心３３０の両端にボビン３１１を挟んでコイル３１０を形成したものを、回転軸４０１の周方向に、等ピッチに放射状に複数配置したものである。 FIG. 2 is a perspective view showing the entire armature 300 of the rotary electric machine according to the first embodiment. A plurality of coils 310 formed by sandwiching bobbins 311 at both ends of the iron core 330 are arranged radially at equal pitches in the circumferential direction of the rotating shaft 401.

図３にコイル３１０の斜視図を示す。図３に示すように、ティース３３１とティース３３１を周方向に外径側で連結するヨーク３３２を備え、複数の鋼板を積層して構成された鉄心３３０と、鉄心３３０の両端に絶縁材からなるボビン３１１を挿入し、絶縁被膜の付いた導体線を巻回したコイル３１０を有している。この導体線は銅線であっても、アルミ線であっても良い。鉄心３３０はヨーク３３２で周方向にティース３３１と同数個に分割されている。実施の形態１では、周方向に分割した鉄心を用いているが、すべての鉄心３３０がヨーク３３２で連結された一体の鉄心であってもよいし、ヨーク３３２を薄肉で連結し、直線状に展開できる鉄心であってもよい。 FIG. 3 shows a perspective view of the coil 310. As shown in FIG. 3, a yoke 332 for connecting the teeth 331 and the teeth 331 on the outer diameter side in the circumferential direction is provided, and the iron core 330 is formed by laminating a plurality of steel plates, and the iron core 330 is composed of insulating materials at both ends. It has a coil 310 into which a bobbin 311 is inserted and a conductor wire having an insulating coating is wound around it. This conductor wire may be a copper wire or an aluminum wire. The iron core 330 is divided into the same number as the teeth 331 in the circumferential direction by the yoke 332. In the first embodiment, an iron core divided in the circumferential direction is used, but all the iron cores 330 may be an integral iron core connected by a yoke 332, or the yoke 332 may be connected by a thin wall to form a straight line. It may be an iron core that can be deployed.

１つのティース３３１は図３に示すように、コイル３１０と鉄心３３０を電気的に隔離するポリフェニレンサルファイド樹脂またはメタ系アラミド繊維からなるシート状のスロットセル３１３を当て、鉄心３３０の両端にボビン３１１を挿入することで固定して絶縁組立を行う。スロットセル３１３の固定は、鉄心３３０の側面に両面テープを付けることで固定しても良い。 As shown in FIG. 3, one tooth 331 is provided with a sheet-shaped slot cell 313 made of polyphenylene sulfide resin or meta-aramid fiber that electrically separates the coil 310 and the iron core 330, and bobbins 311 are placed on both ends of the iron core 330. By inserting it, it is fixed and insulation assembly is performed. The slot cell 313 may be fixed by attaching double-sided tape to the side surface of the iron core 330.

ボビン３１１は図４に示すように、コイル３１０が巻回される胴部３１５と巻線を所定の位置に配置するための壁部３１６を備える。壁部３１６のヨーク３３２側には、結線板３２０を支えるようにクシ歯状の支持壁３１７ａを設けたホルダ部３１７と、ホルダ部３１７の下部には結線板３２０を固定する接着剤を溜めるための容器状の溝部３１８がある。この溝部３１８はホルダ部３１７の支持壁３１７ａとの間に回転軸４０１の周方向に設けられ、その周方向の両端に隔壁３１７ｂを設けることによって容器状に形成される。なお、実施の形態１では、ホルダ部３１７がヨーク３３２側に配置されているが、車両への搭載性を考慮して、回転子４００側に配置してもよい。 As shown in FIG. 4, the bobbin 311 includes a body portion 315 around which the coil 310 is wound and a wall portion 316 for arranging the windings in predetermined positions. A holder portion 317 provided with a comb-shaped support wall 317a so as to support the connection plate 320 on the yoke 332 side of the wall portion 316, and an adhesive for fixing the connection plate 320 are stored in the lower portion of the holder portion 317. There is a container-shaped groove 318. The groove portion 318 is provided between the holder portion 317 and the support wall 317a in the circumferential direction of the rotating shaft 401, and is formed in a container shape by providing partition walls 317b at both ends in the circumferential direction. In the first embodiment, the holder portion 317 is arranged on the yoke 332 side, but may be arranged on the rotor 400 side in consideration of mountability on a vehicle.

図５に実施の形態１の結線板３２０の全体図とその一部の拡大図を示す。結線板３２０は帯状の導材をプレスで打ち抜き加工して形成される。結線板３２０はコイル３１０と接合する給電部３２１と電力が供給される給電部（図示せず）と、ボビン３１１と結合する突出部３２３とで構成される。突出部３２３には、結線板３２０の長手方向の両側に張り出した抜け防止部３２４を設けている。 FIG. 5 shows an overall view of the connection plate 320 of the first embodiment and an enlarged view of a part thereof. The connection plate 320 is formed by punching a strip-shaped guiding material with a press. The connection plate 320 is composed of a power feeding unit 321 that joins the coil 310, a power feeding unit (not shown) to which electric power is supplied, and a protruding portion 323 that connects to the bobbin 311. The protruding portion 323 is provided with pull-out prevention portions 324 protruding on both sides of the connecting plate 320 in the longitudinal direction.

電機子３００の製造工程について図６から図９を用いて説明する。図６にコイル３１０を有する鉄心３３０を円環状に並べた状態を示す。鉄心３３０はフレーム２１１に圧入され図７のように一体化される。ここで、一体化するには鉄心３３０同士を溶接する、または、接着するなどの方法を用いればよい。 The manufacturing process of the armature 300 will be described with reference to FIGS. 6 to 9. FIG. 6 shows a state in which iron cores 330 having coils 310 are arranged in an annular shape. The iron core 330 is press-fitted into the frame 211 and integrated as shown in FIG. Here, in order to integrate the iron cores 330, a method such as welding or bonding the iron cores 330 to each other may be used.

鉄心３３０を一体化した後に図８のようにボビン３１１の容器状の溝部３１８にノズル５０１を用いて接着剤５００を注入する。その後に、図９に示すように結線板３２０を丸め、突出部３２３を溝部３１８に溜められた接着剤５００に浸かる位置まで挿入する。この時の溝部３１８と突出部３２３、接着剤５００の状態を図１０に示す。

After integrating the iron core 330, the adhesive 500 is injected into the container-shaped groove 318 of the bobbin 311 using the nozzle 501 as shown in FIG. After that, as shown in FIG. 9, the connection plate 320 is rolled, and the protruding portion 323 is inserted to a position where it is immersed in the adhesive 500 stored in the groove portion 318. The state of the groove portion 318, the protruding portion 323, and the adhesive 500 at this time is shown in FIG.

図１０を見てわかるように、結線板３２０の突出部３２３は容器状に形成された溝部３１８に溜められた接着剤５００で容器状の溝部３１８に固着される。それによって結線板３２０は一体化された鉄心３３０に固定される。容器状の溝部３１８に挿入された結線板の突出部３２３が接着剤内に埋没するように固着されているので、回転軸の周方向に配置された複数のコイルに対応して結線板を固定することができ、車載用のように高い振動があっても結線板が脱落することのない強固な固定を実現できる。 As can be seen from FIG. 10, the protruding portion 323 of the connection plate 320 is fixed to the container-shaped groove portion 318 with the adhesive 500 stored in the container-shaped groove portion 318. Thereby, the connection plate 320 is fixed to the integrated iron core 330. Since the protruding portion 323 of the connection plate inserted into the container-shaped groove 318 is fixed so as to be buried in the adhesive, the connection plate is fixed corresponding to a plurality of coils arranged in the circumferential direction of the rotation axis. It is possible to realize a strong fixing in which the connection plate does not fall off even if there is a high vibration as in a vehicle.

図９において結線板３２０を固着するための突出部３２３は複数のコイル３１０のうち少なくとも１ヵ所に対応して設ければよいが、複数のコイル３１０に対応して突出部３２３を複数設け、複数ヵ所で固着すれば、より強固な固着強度が得られる。また、接着に要する接着剤５００は、固着を必要とする突出部３２３に対応した容器状の溝部３１８に注入するだけでよく、無用な接着剤５００の使用を抑え、製造コストを節約できる。 In FIG. 9, the protrusion 323 for fixing the connection plate 320 may be provided corresponding to at least one of the plurality of coils 310, but a plurality of protrusions 323 may be provided corresponding to the plurality of coils 310. If it is fixed at a place, stronger fixing strength can be obtained. Further, the adhesive 500 required for adhesion only needs to be injected into the container-shaped groove portion 318 corresponding to the protruding portion 323 that requires adhesion, and the use of unnecessary adhesive 500 can be suppressed and the manufacturing cost can be saved.

さらに、図１０に示す突出部３２３に設けた抜け防止部３２４により、接着面積が増大し、結線板３２０とボビン３１１を強固に固定できる。この時、図１０のように接着剤５００の液面が、抜け防止部３２４の頂部を覆うように構成していると、なお良い。このようにすることで、結線板３２０が抜ける方向に接着剤５００が回り込み、アンカー効果を期待することができる。図１０では抜け防止部３２４が回転軸４０１の周方向に設けた凹部によって突出された例を示したが、図１１のように周方向に凸部が突出された構造でも同様な効果を得られる。 Further, the disconnection prevention portion 324 provided on the protrusion 323 shown in FIG. 10 increases the adhesive area, and the connection plate 320 and the bobbin 311 can be firmly fixed. At this time, it is even better if the liquid level of the adhesive 500 is configured to cover the top of the detachment prevention portion 324 as shown in FIG. By doing so, the adhesive 500 wraps around in the direction in which the connecting plate 320 comes off, and an anchor effect can be expected. FIG. 10 shows an example in which the pull-out prevention portion 324 is projected by a concave portion provided in the circumferential direction of the rotating shaft 401, but the same effect can be obtained with a structure in which the convex portion is projected in the circumferential direction as shown in FIG. ..

その後、結線板３２０とコイル３１０を接続することで電機子３００を得る。接着剤５００は加熱硬化するタイプでも、常温硬化の物でもよいが、加熱硬化の場合は、結線板３２０とコイル３１０の接合時に導体の酸化が影響することが多いため、結線板３２０とコイル３１０の接合後に加熱硬化炉に入れることが望ましい。 After that, the armature 300 is obtained by connecting the connection plate 320 and the coil 310. The adhesive 500 may be a heat-curing type or a room-temperature curing type, but in the case of heat-curing, the oxidation of the conductor often affects the joining of the connecting plate 320 and the coil 310, so that the connecting plate 320 and the coil 310 are affected. It is desirable to put it in a heat curing furnace after joining.

実施の形態２.
実施の形態２では実施形態１で示した結線板３２０の抜け防止部３２４とは異なる構造の例を示す。図１２（Ａ）では実施の形態２の抜け防止部３２４は回転軸４０１の径方向に突出部３２３の面から凸部が突き出した構造となっている。この抜け防止部３２４は結線板３２０の打ち抜き時のプレスで同時に構成してもよいし、打ち抜き後、電機子に組み立てる前に構成してもよい。また、図では抜け防止部３２４を一つの突出部３２３の中で１カ所に構成しているが、複数構成してもよいし、凹部に窪ましてもよい。トタン板の様に波状に構成してもよい。 Embodiment 2.
In the second embodiment, an example of a structure different from the disconnection prevention portion 324 of the connection plate 320 shown in the first embodiment is shown. In FIG. 12A, the pull-out prevention portion 324 of the second embodiment has a structure in which a convex portion protrudes from the surface of the protruding portion 323 in the radial direction of the rotating shaft 401. The pull-out prevention portion 324 may be formed at the same time by pressing the connection plate 320 at the time of punching, or may be formed after punching and before assembling into the armature. Further, in the figure, the pull-out prevention portion 324 is configured at one place in one protruding portion 323, but a plurality of them may be configured or may be recessed in the recess. It may be configured in a wavy shape like a galvanized iron plate.

このような構成とすることで、ボビン３１１の溝部３１８に挿入するときに、径方向のガタを吸収し、結線板３２０の位置を安定して固定することができる。このような径方向のガタを吸収する抜け防止部３２４の構造として、図１２（Ｂ）に示すように突出部３２３から径方向に突き出た切欠きを設けたり、図１２（Ｃ）に示すように突出部３２３の先端を折り曲げるように加工したりしてもよい。 With such a configuration, when the bobbin 311 is inserted into the groove portion 318, the backlash in the radial direction can be absorbed and the position of the connection plate 320 can be stably fixed. As a structure of the pull-out prevention portion 324 that absorbs such play in the radial direction, a notch protruding in the radial direction from the protruding portion 323 as shown in FIG. 12 (B) may be provided, or as shown in FIG. 12 (C). The tip of the protruding portion 323 may be bent.

また、図１２（Ｄ）のように突出部３２３を台形状に打抜いたり、図１２（Ｅ）のように突出部３２３に穴を設けたりすることでも、抜け防止部３２４による接着強度の強化を図ることができる。 Further, by punching the protrusion 323 into a trapezoidal shape as shown in FIG. 12 (D) or by providing a hole in the protrusion 323 as shown in FIG. 12 (E), the adhesive strength is strengthened by the pull-out prevention portion 324. Can be planned.

実施の形態３．
図１３に実施の形態３に係る結線板３２０の突出部３２３を示す。実施の形態３の構造では、抜け防止部３２４を結線板３２０の突出部３２３の先端に凹部を設けたものである。この凹部は電機子に組み立てるときの挿入方向に構成される。 Embodiment 3.
FIG. 13 shows a protruding portion 323 of the connection plate 320 according to the third embodiment. In the structure of the third embodiment, the disconnection prevention portion 324 is provided with a recess at the tip of the protruding portion 323 of the connection plate 320. This recess is configured in the insertion direction when assembling into the armature.

また、ボビン３１１の溝部３１８に、回転軸４０１の軸方向に凸部３１９を設けており、図１４に示すように抜け防止部３２４の凹部と嵌合するよう構成している。ボビン３１１は樹脂の射出成型で製造されることが多く、アンダーカットになるため挿入方向に垂直な凸部が成形しやすい。 Further, the groove portion 318 of the bobbin 311 is provided with a convex portion 319 in the axial direction of the rotating shaft 401, and is configured to fit with the concave portion of the pull-out prevention portion 324 as shown in FIG. The bobbin 311 is often manufactured by injection molding of resin, and since it is undercut, it is easy to mold a convex portion perpendicular to the insertion direction.
