Description

この発明は、回転電機に関するものであり、特にコイルの結線を行うコイル接続体の構造に係るものである。   The present invention relates to a rotating electrical machine, and particularly relates to a structure of a coil connection body for connecting coils.

従来より回転電機のコイル接続構造として、絶縁材からなるホルダに設けた複数の溝部に導電部材を配設したものが示されている（例えば特許文献１参照）。   Conventionally, as a coil connection structure of a rotating electrical machine, a structure in which a conductive member is disposed in a plurality of grooves provided in a holder made of an insulating material has been shown (see, for example, Patent Document 1).

特開２００３−３２４８８３号公報（図４）Japanese Patent Laying-Open No. 2003-324883 (FIG. 4)

しかしながら、前記特許文献１に示されたものは、ホルダが絶縁物を成形加工によって製造されているため、導電部材を配設する溝部が成形加工時の抜き勾配によって入口が広く底が狭くなる形状となっており、そのため、前記溝内に一旦挿入された導電部材が運搬時や組み付け作業などの取扱い時に、溝内から脱するような浮きが発生しやすく、導電部材とコイル端末をヒュージング等に接続する後工程における生産性が悪化したり、導電部材間の絶縁性が低下するという問題点があった。   However, the one shown in Patent Document 1 has a shape in which the holder is manufactured by molding an insulator, so that the groove portion in which the conductive member is disposed has a wide entrance and a narrow bottom due to a draft angle during the molding process. For this reason, the conductive member once inserted into the groove is likely to be lifted off from the groove during handling or handling such as assembly work, and the conductive member and the coil terminal are fused. There is a problem that the productivity in the subsequent process of connecting to the electrode deteriorates or the insulation between the conductive members decreases.

この発明は、前記のような課題を解決するためになされたものであって、導電部材をより容易にかつ確実にホルダ溝内に組み付けることによって、導電部材をホルダ溝内から浮き上がることなく安定した位置に固定可能なコイル接続体構造を備えた回転電機を提供しようとするものである。   The present invention has been made to solve the above-described problems. By assembling the conductive member into the holder groove more easily and reliably, the conductive member can be stabilized without being lifted from the holder groove. An object of the present invention is to provide a rotating electrical machine having a coil connection body structure that can be fixed in position.

この発明に係るコイル接続体を備えた回転電機は、前記コイル接続体は、コイル端末と接続されて所定の結線とする導電部材と、成形加工によって製造され導電部材を溝内で保持する樹脂性の絶縁材からなるホルダとから構成され、ホルダの溝は同心円状に設けられており、導電部材は断面が矩形で略Ｃ字型の形状であるとともに、ホルダの半径方向に導出された腕部を備えたコイル結線用端子部を有し、かつ矩形の側面に突起が設けられており、導電部材の突起がホルダの溝に接して軽圧入されることにより、導電部材がホルダに保持されるものである。 In the rotating electrical machine provided with the coil connection body according to the present invention, the coil connection body is a resin member that is connected to the coil terminal and has a predetermined connection, and is manufactured by molding and holds the conductive member in the groove . The holder is made of an insulating material , and the groove of the holder is provided concentrically. The conductive member has a rectangular cross section and a substantially C shape, and the arm portion led out in the radial direction of the holder. The conductive member is held by the holder when the protrusion of the conductive member is lightly press-fitted in contact with the groove of the holder. Is.

この発明の回転電機は、ホルダの溝内に導電部材を安定した位置に固定することができるので、コイル端末との接続を行う工程の生産性の向上や導電部材間の絶縁性の向上がはかれる。   In the rotating electrical machine of the present invention, the conductive member can be fixed in a stable position in the groove of the holder, so that the productivity in the process of connecting to the coil terminal and the insulation between the conductive members can be improved. .

The coil connection body 14 is configured to be integrated with the stator 3 by engaging an engagement claw 19 provided integrally with the holder 15 with the coil bobbin 11.

図２に示すステータ３の正面図において、コア１０は９個のティース２０を備えており、絶縁体であるコイルボビン１１を装着しティース２０の廻りに９個のコイル１２を有している。コイル１２のコイル端末１３は、紙面手前方向に導出されている。
図３（ａ）は、コイル接続体１４の正面図であって、ナイロン等の樹脂性絶縁材からなるホルダ１５に設けた複数の同心円の溝部１６に正面から見た形状が略Ｃ字型の形状を有する導電部材１７が配設されており、ホルダ１５の半径方向の溝部２０に導電部材１７に構成される腕部２１が挿通しており、腕部２１の端末にコイル接続端子１８が構成されている。図３（ｂ）は、図３（ａ）の腕部２１、コイル接続端子１８を含む断面を有している。導電部材１７は凹部２２を備えており、ホルダ１５に備えられた凸部２３と係合し、導電部材１７の円周方向の回り止めを成している。

The coil terminal 13 of the coil 12 is led out toward the front of the page.
FIG. 3A is a front view of the coil connection body 14, and the shape of the concentric groove portions 16 provided on the holder 15 made of a resinous insulating material such as nylon is substantially C-shaped. A conductive member 17 having a shape is disposed, an arm portion 21 configured in the conductive member 17 is inserted into a groove portion 20 in the radial direction of the holder 15, and a coil connection terminal 18 is configured at the end of the arm portion 21.

The conductive member 17 includes a concave portion 22, engages with a convex portion 23 provided in the holder 15, and forms a detent in the circumferential direction of the conductive member 17.
4 is a coil connection diagram. When the coil terminal 13 shown in FIG. 2 and the coil connection terminal 18 shown in FIG. 3 are connected by fusing or the like, the three-phase parallel Y connection shown in FIG. It is composed.

図５（ａ）において、ナイロン等の樹脂性絶縁材からなるホルダ１５に設けられた複数の溝部１６に正面形状が略Ｃ字型の形状を有する複数の導電部材１７が 配設されており、前記導電部材１７は側面にプレス等で形成された突起２４を備えている。なお、凹部２４ａは前記突起２４をプレス形成時のへこみである。図５（ｂ）に示すように導電部材１７の突起２４はホルダ１５の溝部１６に接して軽圧入されている。
このように、この実施の形態１に示した構成のコイル接続体１４は、導電部材１７の突起２４がホルダ溝部１６の側面に接して挿入されているので、前記突起２４と溝部１６との側圧によって固定されることになる。従ってたとえホルダ１５の溝部１６が抜き勾配により入口が広く底が狭くなる形状を有していても、コイル接続体１４の運搬時や取り扱い時等に、一旦挿入した導電部材１７の外れや浮きが発生することがない。これにより、導電部材１７の腕部２１に設けられたコイル接続端子１８は位置精度を確保することができるため、コイル接続端子１８とコイル端末１３をヒュージング等により接続する後工程において生産性が向上でき、導電部材１７間の絶縁性も向上することが出来る。また、追加部材を使用せずに導電部材１７の外れや浮きを改善することができ、コストＵＰを抑制することが可能となる。 In FIG. 5A, a plurality of conductive members 17 having a substantially C-shaped front surface are disposed in a plurality of grooves 16 provided in a holder 15 made of a resinous insulating material such as nylon.

As described above, in the coil connector 14 having the configuration shown in the first embodiment, since the protrusion 24 of the conductive member 17 is inserted in contact with the side surface of the holder groove portion 16, the lateral pressure between the protrusion 24 and the groove portion 16 is increased. It will be fixed by. Therefore, even if the groove portion 16 of the holder 15 has a shape in which the entrance is wide and the bottom is narrow due to the draft, the conductive member 17 once inserted is detached or floated when the coil connector 14 is transported or handled. It does not occur. Thereby, since the coil connection terminal 18 provided on the arm portion 21 of the conductive member 17 can ensure the positional accuracy, the productivity is increased in the subsequent process of connecting the coil connection terminal 18 and the coil terminal 13 by fusing or the like. The insulation between the conductive members 17 can also be improved. Further, the detachment and floating of the conductive member 17 can be improved without using an additional member, and the cost can be suppressed.

また、前記突起は導電部材１７の略Ｃ字型形状に沿った矩形の片方の側面に１個所または複数個所設けてもよく、またさらに両方の側面にそれぞれ１個所または複数個所設けてもよい。
また突起２４の形状は、凸状、球状、円錐状等いずれの形状であってもよく、導電部材１７からプレス成形時の生産性やホルダ１５に導電部材１７の挿入時の作業性等から最適なものを選択すればよい。 In addition, although the example which provides the protrusion 24 in the electrically-conductive member 17 shown in this Embodiment 1 was shown, the following may be sufficient. That is, a plurality of protrusions may be formed on the rectangular side surface of the conductive member 17 along the substantially C-shape by pressing or the like.
Further, one or a plurality of the protrusions may be provided on one side surface of the rectangular shape along the substantially C-shape of the conductive member 17, and one or a plurality of the protrusions may be provided on both side surfaces.
Further, the shape of the protrusion 24 may be any shape such as a convex shape, a spherical shape, and a conical shape, and is optimal from the productivity at the time of press molding from the conductive member 17 and the workability at the time of inserting the conductive member 17 into the holder 15. You can choose the right one.

次に、この発明の実施の形態２を図６に基づいて説明する。
図６は前記実施の形態１の図５に相当する他の実施例を示すもので、図６（ａ）のコイル接続体１４ａは、断面長方形状であって正面形状が略Ｃ字型形状の導電部材１７ａがホルダ１５ａの溝部１６ａの溝内側部に設けられた突起２５に接して軽圧入挿入された状態を示したものである。図６（ｂ）は図６（ａ）のＡ−Ａ断面図を示す。
突起２５は、ホルダ１５ａに設けられた複数の同心円の溝部１６ａの円周方向に設けられている。前記突起２５の円周方向に設置された数は、図６（ａ）に示す例では前記複数の導電部材１７ａの数と同数であるが、必ずしも同数である必要はなく、ホルダ１５ａの同一円周上に前記導電部材１７ａの数より多い複数個所設けてもよく、またさらに溝部１６ａの半径方向に例えば内径側と外径側にそれぞれ１個所ずつ円周上に複数個所設けてもよい。
なお当然のことながら、前記突起２５は、前記複数の導電部材１７ａが前記溝部１６ａに挿入された際、前記導電部材１７ａが接するような円周上の位置に設けなければならない。また突起２５は断面が長方形状、凸状、球状、円錐状のいずれであってもよい。 Embodiment 2. FIG.

FIG. 6 shows another example corresponding to FIG. 5 of the first embodiment. The coil connection body 14a in FIG. 6 (a) has a rectangular cross section and a front shape of a substantially C shape. This shows a state where the conductive member 17a is lightly press-inserted into contact with the protrusion 25 provided on the groove inner portion of the groove portion 16a of the holder 15a. FIG. 6B is a cross-sectional view taken along the line AA in FIG.
The protrusion 25 is provided in the circumferential direction of a plurality of concentric grooves 16a provided on the holder 15a. The number of the protrusions 25 installed in the circumferential direction is the same as the number of the plurality of conductive members 17a in the example shown in FIG. 6A, but is not necessarily the same, and the same circle of the holder 15a. More than the number of the conductive members 17a may be provided on the circumference, and more than one may be provided on the circumference, for example, one on the inner diameter side and one on the outer diameter side in the radial direction of the groove 16a.
As a matter of course, the protrusion 25 must be provided at a position on the circumference where the conductive member 17a contacts when the plurality of conductive members 17a are inserted into the groove 16a. Further, the protrusion 25 may have a rectangular, convex, spherical, or conical cross section.

このように、この実施の形態２では、前記実施の形態１と同様にホルダ溝部１６ａに設けた突起２５に接するよう導電部材１７ａが軽圧入されているので、略Ｃ字型の形状の導電部材１７ａと突起２５との側圧により固定されることになり、前記実施の形態１と同様の効果を奏する。   As described above, in the second embodiment, the conductive member 17a is lightly press-fitted so as to be in contact with the protrusion 25 provided in the holder groove portion 16a as in the first embodiment. It will be fixed by the side pressure of 17a and protrusion 25, and there exists an effect similar to the said Embodiment 1. FIG.

図７（ａ）はコイル接続体１４ｂの正面図、図７（ｂ）は図７（ａ）のＡ−Ａ断面図、図７（ｃ）は図７（ａ）のＢ−Ｂ断面を示す図である。図７（ｃ）から判るように、ホルダ１５ｂの溝部１６ｂには断面長方形状であって正面の形状が略Ｃ字型をなす導電部材１７ａが挿入されており、前記導電部材１７ａはホルダ１５ｂに設けたカシメ部５１にて例えば加熱によりコーキングを施されることにより溝頭部を変形させ、前記導電部材１７ａがホルダ１５ｂの溝部１６ｂ内に保持されている。
前記カシメ部５１によるコーキングは略Ｃ字型形状の導電部材１７ａ上に複数個所設けてもよい。
このような構成を採用することにより、たとえホルダ１５ｂの溝部１６ｂが抜き勾配により入口が広く、底が狭くなるような形状を有していても、前記実施の形態１と同様の効果を奏する。 Embodiment 3 FIG.
Next, Embodiment 3 will be described with reference to FIG.
7A is a front view of the coil connection body 14b, FIG. 7B is a cross-sectional view taken along the line AA in FIG. 7A, and FIG. 7C is a cross-sectional view taken along the line BB in FIG. FIG.

The conductive member 17a is inserted into the holder 15b. The groove head portion is deformed by caulking, for example, by heating in the caulking portion 51 provided, and the conductive member 17a is held in the groove portion 16b of the holder 15b.
A plurality of caulks by the caulking portion 51 may be provided on the substantially C-shaped conductive member 17a.
By adopting such a configuration, even if the groove portion 16b of the holder 15b has a shape in which the entrance is wide and the bottom is narrow due to the draft, the same effect as in the first embodiment is obtained.

実施の形態４．
次に実施の形態４を図８に基づいて説明する。

図８（ｂ）（ｃ）に示すようにホルダ１５ｂの溝部１６ｂには前記突起５２を有し、断面長方形状の導電部材１７ｂが挿入されており、ホルダ１５ｂに設けたカシメ部５１ａにて導電部材１７ｂの突起５２にそうよう例えば加熱によりコーキングを施されることによって導電部材１７ｂをホルダ１５ｂの溝部１６ｂ内に保持している。
なお前記突起５２の形状は、凸状、球状、円錐状等いずれの形状であってもよく、導電部材１７ｂの生産性や、コーキング作業性等から最適なものを選択すればよい。
このような構成を採用することによっても、前記実施の形態１と同様の効果を奏する。またさらに導電部材１７ｂの突起５２とホルダ１５ｂのカシメ部５１ａが係合しているので、導電部材１７ｂの周方向の位置決めも行うこともでき、前記実施の形態１の図３（ｂ）で示したホルダ１５に設けた凸部２３および導電部材１７の凹部を不要とすることもできるという効果もある。 Embodiment 4 FIG.

The shape of the protrusion 52 may be any shape such as a convex shape, a spherical shape, and a conical shape, and an optimal one may be selected from the productivity of the conductive member 17b, the caulking workability, and the like.
By adopting such a configuration, the same effects as those of the first embodiment can be obtained. Further, since the protrusion 52 of the conductive member 17b and the crimped portion 51a of the holder 15b are engaged, the conductive member 17b can also be positioned in the circumferential direction, as shown in FIG. 3B of the first embodiment. There is also an effect that the convex portion 23 provided on the holder 15 and the concave portion of the conductive member 17 can be eliminated.
