Description

本発明は、モータ用の集中配電部品に関し、特に車両に搭載されるモータ用の集中配電部品に関する。   The present invention relates to a central power distribution component for a motor, and more particularly to a central power distribution component for a motor mounted on a vehicle.

近年、環境を重視して省燃費化をはかるために、ハイブリッドカーの開発が行われている。ハイブリッドカーは、自動車の主動力源としては化石燃料用いたエンジンを用いて、このエンジンをアシストするためのモータアシスト機構を備えている。   In recent years, hybrid cars have been developed in order to save energy with an emphasis on the environment. The hybrid car uses an engine using fossil fuel as the main power source of the automobile and includes a motor assist mechanism for assisting the engine.

自動車に用いられるモータは、例えばエンジンのシャフトに直結されたロータと、このロータの周囲に配置されたリング状のステータを備えている。このステータは、コアに複数の巻線を施すことにより形成された多数の磁極と、これらの磁極を収納しているホルダと、複数の巻線に対して集中的に配電を行うための集中配電部材を有する。   A motor used in an automobile includes, for example, a rotor directly connected to an engine shaft, and a ring-shaped stator disposed around the rotor. This stator has a large number of magnetic poles formed by applying a plurality of windings to a core, a holder that accommodates these magnetic poles, and a concentrated power distribution to distribute power intensively to the plurality of windings. It has a member.

従来の集中配電部材は、U相、V相、W相のバスバーを有している。各バスバーは、バッテリ側に接続される端子と、ステータの複数の巻線側に接続されるタブを有している。このバスバーは、導電性金属板材を打ち抜くことにより形成され、その後円環状に折り曲げられる(例えば、特許文献1参照)。   A conventional concentrated power distribution member has U-phase, V-phase, and W-phase bus bars. Each bus bar has a terminal connected to the battery side and a tab connected to the plurality of windings of the stator. This bus bar is formed by punching a conductive metal plate, and then bent into an annular shape (see, for example, Patent Document 1).

また、別の形式の集中配電部材は、U相、V相、W相の3つの円環状の電線部材と帯状部材を有し、3つの円環状の電線部材は、絶縁性の帯状部材を折り曲げることで、帯状部材の溝に収納するようになっているものがある(例えば、特許文献2参照)。
特許第3717833号公報 特開2005−160137号公報
Another type of concentrated power distribution member has three annular electric wire members of U phase, V phase, and W phase and a strip member, and the three annular electric wire members bend the insulating strip member. Thus, there is one that is housed in the groove of the belt-like member (for example, see Patent Document 2).
Japanese Patent No. 3717833 JP 2005-160137 A

ところが、特許文献1の集中配電部材では、各バスバーは、導電性金属板材を打ち抜くことにより形成されるので、導電性金属板材を打ち抜いた後の導電性金属板材の残部が多く、バスバーを製造する場合の導電性材料の歩留まりが悪いばかりでなく、打ち抜かれた各バスバーは、正確に円環状に折り曲げる必要があるので、組み立て加工性が悪い。   However, in the concentrated power distribution member of Patent Document 1, each bus bar is formed by punching out a conductive metal plate, so that there are many remaining portions of the conductive metal plate after punching out the conductive metal plate, and the bus bar is manufactured. In this case, not only the yield of the conductive material is bad, but also each punched bus bar needs to be bent accurately in an annular shape, so that the assembly workability is poor.

また、特許文献2の集中配電部材では、3つの円環状の電線部材を取り扱わなければならないので組み立て作業が面倒であり、3つの円環状の配線部材の内側には、それぞれ複数のタブを折り曲げるようにして突出して形成しなければならず、組み立て加工性を向上できない。   Further, in the centralized power distribution member of Patent Document 2, since three annular electric wire members must be handled, the assembly work is troublesome, and a plurality of tabs are bent inside each of the three annular wiring members. Thus, it must be formed so as to protrude, and the assembly workability cannot be improved.

そこで、本発明は上記課題を解消し、歩留まりを上げながら組み立て加工性を向上できる集中配電部品を提供することを目的とする。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a centralized power distribution component capable of solving the above-described problems and improving assembly workability while increasing yield.

次に、図7と図8を参照して、集電部20について説明する。   Next, the current collector 20 will be described with reference to FIGS. 7 and 8.

集電部20は、中性点リングあるいは中立点リングとも呼ぶことができ、帯状の本体部21と複数の接続突起22を有している。この集電部20は、例えば銅またはアルミニウムなどの導電性板材を打ち抜くことで作られており、複数の接続突起22は、図1に示す収納部材30の内周方向に突出している。   The current collector 20 can also be called a neutral point ring or a neutral point ring, and has a band-shaped main body 21 and a plurality of connection protrusions 22. The current collector 20 is made by punching a conductive plate such as copper or aluminum, and the plurality of connection protrusions 22 protrude in the inner peripheral direction of the storage member 30 shown in FIG.

集電部20の複数の接続突起22は、図9に示すようにU相とV相とW相の巻線100,101,102の他方端103側に接続されている。U相とV相とW相の巻線100,101,102の一方端105側は、図2ないし図4に示すU相とV相とW相の電気伝導部材10,11,12の終端部71に対してそれぞれ接続される。   The plurality of connection protrusions 22 of the current collector 20 are connected to the other end 103 side of the U-phase, V-phase, and W-phase windings 100, 101, 102 as shown in FIG. One end 105 side of the U-phase, V-phase, and W-phase windings 100, 101, 102 is a terminal portion of the U-phase, V-phase, and W-phase electrically conductive members 10, 11, 12 shown in FIGS. 71 are connected to each other.

次に、図10ないし図12を参照して、環状の収納部材30の構造を説明する。   Next, the structure of the annular storage member 30 will be described with reference to FIGS.

図10に示すように、収納部材30は、リング状の電気絶縁部材であり、図10(C)と図11に示すような断面形状を有している。収納部材30は、内周壁80,区分壁81,82,83、84を有している。   As shown in FIG. 10, the storage member 30 is a ring-shaped electrical insulating member and has a cross-sectional shape as shown in FIG. 10C and FIG. 11. The storage member 30 has an inner peripheral wall 80 and partition walls 81, 82, 83, and 84.

内周壁80,区分壁81,82,83、84は、収納部材30の長手方向(円周方向)に沿って互いに平行に形成されている。内周壁80と区分壁81の間には、U相に対応する電気伝導部材10を収納する収納溝91が形成されている。同様にして、区分壁81,82の間には、V相に対応する電気伝導部材11を収納する収納溝92が形成されている。区分壁82,83の間には、W相に対応する電気伝導部材12を収納する収納溝93が形成されている。内周壁80と区分壁81の間に形成されている収納溝94には、集電部20の本体部21が収納されている。集電部20の接続突起22は、収納部材30の内周方向Rに突出している。収納溝91,92,93は、電気伝導部材10、11,12をそれぞれ収納するための第1収納溝である。収納溝94は、集電部20を収納するための第2収納溝である。   The inner peripheral wall 80 and the partition walls 81, 82, 83, 84 are formed in parallel to each other along the longitudinal direction (circumferential direction) of the storage member 30. Between the inner peripheral wall 80 and the partition wall 81, a storage groove 91 for storing the electrically conductive member 10 corresponding to the U phase is formed. Similarly, a storage groove 92 for storing the electrical conductive member 11 corresponding to the V phase is formed between the partition walls 81 and 82. A storage groove 93 is formed between the partition walls 82 and 83 to store the electrical conductive member 12 corresponding to the W phase. The storage groove 94 formed between the inner peripheral wall 80 and the partition wall 81 stores the main body 21 of the current collector 20. The connection protrusion 22 of the current collector 20 protrudes in the inner circumferential direction R of the storage member 30. The storage grooves 91, 92, and 93 are first storage grooves for storing the electrical conductive members 10, 11, and 12, respectively. The storage groove 94 is a second storage groove for storing the current collector 20.

次に、集中配電部品1の組立て加工手順例について説明する。   Next, an example of an assembly processing procedure for the concentrated power distribution component 1 will be described.

図10に示す収納部材30と、図2ないし図4に示すU相に対応する電気伝導部材10と、V相に対応する電気伝導部材11と、W相に対応する電気伝導部材12を用意して、3相の電気伝導部材10,11,12は、図11に示すように、それぞれ収納溝91,92,93に収納する。3相の電気伝導部材10,11,12は、予め円形状になっているが、完全な環状体ではないので、円環状の収納溝91,92,93に対して、簡単かつ確実に装着できる。この場合に、図1に示すように、3相の電気伝導部材10,11,12は、少しずつ円周方向にずらして配置することで、U相の終端部71,とV相の終端部71,W相の終端部71が順次円周方向に沿って配置される。   A storage member 30 shown in FIG. 10, an electric conduction member 10 corresponding to the U phase shown in FIGS. 2 to 4, an electric conduction member 11 corresponding to the V phase, and an electric conduction member 12 corresponding to the W phase are prepared. The three-phase electrically conductive members 10, 11, and 12 are housed in the housing grooves 91, 92, and 93, respectively, as shown in FIG. Although the three-phase electrically conductive members 10, 11, and 12 are circular in advance, they are not perfect annular bodies, and thus can be easily and reliably attached to the annular storage grooves 91, 92, and 93. . In this case, as shown in FIG. 1, the three-phase electrically conductive members 10, 11, and 12 are arranged slightly shifted in the circumferential direction so that the U-phase termination portion 71 and the V-phase termination portion are arranged. 71, W-phase end portions 71 are sequentially arranged along the circumferential direction.

3相の電気伝導部材10,11,12の各電線の始端部70は、接続端子部材74を用いて例えばバッテリ側に接続され、各電線の終端部71は、図9に示す各相のコイル100,101,102の一端部105に接続される。図11と図12に示すように、収納部材30の収納溝94には集電部20が収納される。集電部20の接続端子22は、図9に示すように各相のコイルの他端部103に接続される。   The starting end portion 70 of each electric wire of the three-phase electrically conductive members 10, 11, 12 is connected to, for example, the battery side using the connection terminal member 74, and the terminal portion 71 of each electric wire is a coil of each phase shown in FIG. Connected to one end 105 of 100, 101, 102. As shown in FIGS. 11 and 12, the current collector 20 is stored in the storage groove 94 of the storage member 30. As shown in FIG. 9, the connection terminal 22 of the current collector 20 is connected to the other end 103 of each phase coil.

これにより、バッテリからモータのコイル100,101,102に通電する際には、バッテリ側からの駆動電流が、3相の電気伝導部材10,11,12を通じて、図9の3相のコイル100,101,102に対して供給される。   Thus, when the motor coils 100, 101, 102 are energized from the battery, the drive current from the battery side passes through the three-phase electrical conductive members 10, 11, 12, and the three-phase coils 100, FIG. 101 and 102 are supplied.

上述した集中配電部品1では、3相の電気伝導部材10,11,12がそれぞれ複数本の電線により構成されており、電気伝導部材10,11,12を構成するために導電性金属板を打ち抜く必要が無く、導電性金属板を使用しないので歩留まりが低下しない。しかも電線の集合体であるので、取り扱いが容易である。3相の電気伝導部材10,11,12と集電部30は、円環状の収納部品20の収納溝に沿ってはめ込むだけで簡単に組み立て加工することができる。従って、本発明の第1の実施形態の集中配電部品1を製造する際の歩留まりを上げながら、組み立て加工性を向上できる。   In the concentrated power distribution component 1 described above, the three-phase electrically conductive members 10, 11, and 12 are each composed of a plurality of electric wires, and a conductive metal plate is punched out to form the electrically conductive members 10, 11, and 12. There is no need, and a conductive metal plate is not used, so the yield does not decrease. And since it is an aggregate | assembly of an electric wire, handling is easy. The three-phase electrically conductive members 10, 11, 12 and the current collector 30 can be easily assembled and processed simply by being fitted along the storage groove of the annular storage component 20. Therefore, it is possible to improve the assembly workability while increasing the yield when manufacturing the concentrated power distribution component 1 of the first embodiment of the present invention.

The connection protrusion 22 protrudes from the main body portion 21 along the inner circumferential direction T. The storage member 30 has a storage groove 190 and a storage groove 194. The storage groove 190 has a U-shaped cross section, and in the storage groove 190, the electric conduction member 10 corresponding to the U phase, the electric conduction member 11 corresponding to the V phase, and the electric conduction corresponding to the W phase. The members 12 are laminated in order. In the example of FIG. 13, each electric wire is an enameled wire, and the thickness is the same. The storage groove 194 stores the main body 21 of the current collector 20. The storage groove 190 is a first storage groove. The storage groove 194 is a second storage groove.

図13に示すように、U相に対応する電気伝導部材10と、V相に対応する電気伝導部材11と、W相に対応する電気伝導部材12は、別々に絶縁紙300により電気絶縁されており、収納溝190内にはワニス301が含侵されている。   As shown in FIG. 13, the electrical conductive member 10 corresponding to the U phase, the electrical conductive member 11 corresponding to the V phase, and the electrical conductive member 12 corresponding to the W phase are electrically insulated by the insulating paper 300 separately. The storage groove 190 is impregnated with the varnish 301.

Since it is an assembly of electric wires, it is easy to handle. Moreover, the three-phase electrically conductive members 10, 11, 12 and the current collector 20 can be easily assembled and processed simply by being fitted along the storage groove of the annular storage component 30.

(第3の実施形態)
図15と図16を参照して、本発明の集中配電部品の好ましい第3の実施形態を説明する。
(Third embodiment)
With reference to FIGS. 15 and 16, a third preferred embodiment of the centralized power distribution component of the present invention will be described.

図15は、U相に対応する電気伝導部材10と、V相に対応する電気伝導部材11と、W相に対応する電気伝導部材12と、集電部220と、収納部材230を示す断面図である。図16は、代表して電気伝導部材100,11,12の各4本の電線を示す図である。   FIG. 15 is a cross-sectional view showing the electrical conductive member 10 corresponding to the U phase, the electrical conductive member 11 corresponding to the V phase, the electrical conductive member 12 corresponding to the W phase, the current collector 220, and the storage member 230. It is. FIG. 16 is a diagram showing four electric wires of the electric conductive members 100, 11, and 12 as representatives.

図15の第3の実施形態が、図13の第2の実施形態と異なるのは、電線の太さであり、U相に対応する電気伝導部材10の電線40,41,42,43と、V相に対応する電気伝導部材11の電線50,51,52,53と、W相に対応する電気伝導部材12の電線60,61,62,63は、長さが長くなるのに従って、太くなっている。この太さの変更については、図示はしていないが、図2に示すU相に対応する電気伝導部材10の電線44,45,46,47と、図3に示すV相に対応する電気伝導部材11の電線54,55,56,57と、図4に示すW相に対応する電気伝導部材12の電線64,65,66,67についても同様である。   The third embodiment of FIG. 15 differs from the second embodiment of FIG. 13 in the thickness of the electric wire, and the electric wires 40, 41, 42, 43 of the electric conductive member 10 corresponding to the U phase, The electric wires 50, 51, 52, and 53 of the electric conductive member 11 corresponding to the V phase and the electric wires 60, 61, 62, and 63 of the electric conductive member 12 corresponding to the W phase become thicker as the length becomes longer. ing. The thickness change is not shown, but the electric wires 44, 45, 46, 47 of the electric conduction member 10 corresponding to the U phase shown in FIG. 2 and the electric conduction corresponding to the V phase shown in FIG. The same applies to the electric wires 54, 55, 56, and 57 of the member 11 and the electric wires 64, 65, 66, and 67 of the electric conductive member 12 corresponding to the W phase shown in FIG.

このように、電線の太さを変えるのは、各電線における電気抵抗の数値を揃えることにより、集中配電部品1から各巻線に対して供給する電流値を一定にすることで、モータの動作効率の改善を図るためである。   As described above, the thickness of the electric wire is changed by making the electric current supplied from the centralized power distribution component 1 to each winding constant by aligning the numerical values of the electric resistances of the respective electric wires. This is for the purpose of improvement.

一例として、図16に例示するように、最も短い電線43の抵抗をR1とし、2番目に短い電線42の抵抗をR2とし、3番目に短い電線41の抵抗をR3とし、最も長い電線40の抵抗をR4とする。例えば、最も細い電線43の断面積を0.3716mm、電線42の断面積を0.789mm、電線41の断面積を1.282mm、そして電線40の断面積を1.964mmとした場合には、各抵抗値は次のようになる。
R1=(2×10ー6(Ωcm)/0.003716(cm))×30(cm)×π×(1.5/24)=0.00317(Ω)
R2=(2×10ー6(Ωcm)/0.00789(cm))×30(cm)×π×(4.5/24)=0.00448(Ω)
R3=(2×10ー6(Ωcm)/0.01282(cm))×30(cm)×π×(7.5/24)=0.004595(Ω)
R4=(2×10ー6(Ωcm)/0.01964(cm))×30(cm)×π×(10.5/24)=0.004199(Ω)
このように、各電線の抵抗R1ないしR4は、ほぼ揃えることができる。例えば直径を30(cm)とした場合に30(cm)×πは円周長さであり、(1.5/24)は、円周方向の長さを24等分したときにおける1.5の長さに相当することを示している。
As an example, as illustrated in FIG. 16, the resistance of the shortest electric wire 43 is R1, the resistance of the second shortest electric wire 42 is R2, the resistance of the third shortest electric wire 41 is R3, and The resistance is R4. For example, the cross-sectional area of the thinnest wire 43 0.3716mm 2, 0.789mm 2 the cross-sectional area of the wire 42, 1.282mm 2 the cross-sectional area of the wire 41, and the cross-sectional area of the wire 40 was 1.964Mm 2 In this case, each resistance value is as follows.
R1 = (2 × 10 over 6 (Ωcm) /0.003716 (cm 2 )) × 30 (cm) × π × (1.5 / 24) = 0.00317 (Ω)
R2 = (2 × 10 over 6 (Ωcm) /0.00789 (cm 2 )) × 30 (cm) × π × (4.5 / 24) = 0.00448 (Ω)
R3 = (2 × 10 over 6 (Ωcm) /0.01282 (cm 2 )) × 30 (cm) × π × (7.5 / 24) = 0.004595 (Ω)
R4 = (2 × 10 over 6 (Ωcm) /0.01964 (cm 2 )) × 30 (cm) × π × (10.5 / 24) = 0.004199 (Ω)
As described above, the resistances R1 to R4 of the respective electric wires can be substantially uniform. For example, when the diameter is 30 (cm), 30 (cm) × π is the circumferential length, and (1.5 / 24) is 1.5 when the circumferential length is divided into 24 equal parts. It corresponds to the length of.

上述した集中配電部品1では、3相の電気伝導部材10,11,12がそれぞれ複数本の電線により構成されており、電気伝導部材10,11,12を構成するのは金属板を打ち抜く必要が無く、しかも電線の集合体であるので、取り扱いが容易である。しかも、3相の電気伝導部材10,11,12と集電部20は、円環状の収納部品30の収納溝に沿ってはめ込むだけで簡単に組み立て加工することができる。従って、本発明の第3の実施形態の集中配電部品1を製造する際の歩留まりを上げながら、組み立て加工性を向上できる。   In the concentrated power distribution component 1 described above, the three-phase electrical conductive members 10, 11, and 12 are each composed of a plurality of electric wires, and the electrical conductive members 10, 11, and 12 need to be punched out of a metal plate. Since it is an assembly of electric wires, it is easy to handle. Moreover, the three-phase electrically conductive members 10, 11, 12 and the current collector 20 can be easily assembled and processed simply by being fitted along the storage groove of the annular storage component 30. Therefore, it is possible to improve the assembly workability while increasing the yield when manufacturing the concentrated power distribution component 1 of the third embodiment of the present invention.

本発明の実施形態では、複数相の電気伝導部材の各電線の始端部は、端子部に結束して接続されているので、取り扱いが容易である。収納部材は、複数相の電気伝導部材の複数の電線を第1収納溝において別々に収納するので、相互の絶縁性を確保することができる。集電部は第2収納溝に収納できるので、組み立て加工性が向上する。   In the embodiment of the present invention, since the starting end portion of each electric wire of the multi-phase electric conductive member is bound and connected to the terminal portion, it is easy to handle. Since the storage member separately stores the plurality of electric wires of the multi-phase electrically conductive member in the first storage groove, mutual insulation can be secured. Since the current collector can be stored in the second storage groove, the assembly processability is improved.

本発明の集中配電部品の実施形態によれば、各電気伝導部材は完全な環状部材にしなくて済み複数の電線から構成されているので、完全な環状部材の物に比べて、環状の収納部材の収納溝に対して簡単に装着でき、歩留まりを上げながら組み立て加工性を向上できる。   According to the embodiment of the centralized power distribution component of the present invention, each electric conductive member does not have to be a complete annular member, and is composed of a plurality of electric wires. It can be easily installed in the storage groove, and the assembly processability can be improved while increasing the yield.

本発明の集中配電部品の実施形態によれば、収納部材は、複数相の電気伝導部材の複数の電線を収納する第1収納溝と、集電部を収納する第2収納溝とを有しているので、複数相の電気伝導部材と集電部は簡単に絶縁性を確保しながら収納できる。   According to the embodiment of the centralized power distribution component of the present invention, the storage member has a first storage groove for storing the plurality of electric wires of the multi-phase electrical conductive member and a second storage groove for storing the current collector. Therefore, the multi-phase electrically conductive member and the current collecting part can be easily accommodated while ensuring insulation.

集電部は、導電性板材を打ち抜くことで作られており、収納部材の内周方向に突出して、巻線の他方端側に接続される接続突起を有しているので、集電部は簡単に造ることができる。   The current collector is made by punching out a conductive plate, and protrudes in the inner circumferential direction of the storage member and has a connection protrusion connected to the other end side of the winding, so the current collector is Easy to build.

収納部材は、電線の終端部を通して固定する終端部固定溝を有しているので、各終端部は簡単に固定できることから組み立て加工性が向上する。   Since the storage member has a terminal end fixing groove that is fixed through the terminal end of the electric wire, each terminal can be easily fixed, so that assembly workability is improved.

複数の電線は、電線の長さが長いほど太くなっていることから、各電線における抵抗値を揃えることができ、集中配電部品1から各巻線に対して供給する電流値を一定にすることで、モータの動作効率の改善を図ることができる。   Since the plurality of electric wires are thicker as the length of the electric wires is longer, the resistance values of the electric wires can be made uniform, and the current value supplied from the concentrated power distribution component 1 to each winding can be made constant. The operational efficiency of the motor can be improved.

電線は、第1収納溝において絶縁紙にまかれワニスにより覆われていることから、各電線の絶縁性を確保できる。   Since the electric wire is covered with insulating paper in the first storage groove and covered with varnish, the electric insulation of each electric wire can be secured.

本発明の実施形態では、各電気伝導部材10,11,12は、完全な環状部材ではないので、完全な環状部材の物に比べて、環状の収納部材の収納溝に対して簡単に装着できる。また、各電気伝導部材10,11,12は、環状の収納部材でなく、直線状の収納部材の収納溝に対しても簡単に装着でき、その後収納部材は環状に加工できる。   In the embodiment of the present invention, since each of the electrically conductive members 10, 11, and 12 is not a complete annular member, it can be easily attached to the storage groove of the annular storage member as compared with a complete annular member. . In addition, each of the electric conductive members 10, 11, and 12 can be easily mounted not only on the annular storage member but also on the storage groove of the linear storage member, and then the storage member can be processed into an annular shape.

ところで、本発明は、上記実施形態に限定されず種々の変形例を採用できる。   By the way, this invention is not limited to the said embodiment, A various modified example is employable.

例えば、第1の実施形態と第2の実施形態では、各電線の太さが同じであるが、これに限らず電線の長さが短ければ細くして、電線の長さが長ければ太くするようにしても良い。   For example, in the first embodiment and the second embodiment, the thickness of each electric wire is the same, but not limited to this, if the length of the electric wire is short, it is thinned, and if the length of the electric wire is long, it is thickened. You may do it.
