Description

この発明は、車両用交流発電機などの回転電機に発生した交流を直流に変換する整流装置並びに整流装置における整流素子の固定方法に関するものである。   The present invention relates to a rectifier that converts alternating current generated in a rotating electrical machine such as an automotive alternator into direct current, and a method of fixing a rectifier element in the rectifier.

従来の車両用交流発電機の整流装置は、円弧状のフィンベース（冷却部材）の側面に整流素子を半田付けにより固定している（例えば特許文献１）。
また、半円弧状のフィンベースを二重リング状に配置し、それぞれ内側リング内周面と外側リング外周面とに径方向に延びる冷却フィンが多数設けられ、フィンベースの冷却フィン背面側にダイオードが取り付けられるものが開示されている（例えば、特許文献２）。
このような構成にすることで、車両用発電機の外形形状を増大することなく、円形断面を持つ車両用発電機内でフィン面積の増大が可能になり、結果、増大する電流出力に対応できる旨記載されている。 In a conventional rectifier for an AC generator for a vehicle, a rectifying element is fixed to a side surface of an arc-shaped fin base (cooling member) by soldering (for example, Patent Document 1).
A semi-arc-shaped fin base is arranged in a double ring shape, and a large number of cooling fins extending in the radial direction are provided on the inner peripheral surface of the inner ring and the outer peripheral surface of the outer ring, respectively. Is disclosed (for example, Patent Document 2).
With such a configuration, it is possible to increase the fin area in the vehicular generator having a circular cross section without increasing the outer shape of the vehicular generator, and as a result, it is possible to cope with an increasing current output. Are listed.

特開２００６−２６２６４４号公報（第５頁、図４）Japanese Patent Laying-Open No. 2006-262644 (5th page, FIG. 4) 特許２６６９５３４号公報（第３頁、図２）Japanese Patent No. 2669534 (page 3, FIG. 2)

特許文献２に記載のものではフィン面積の増大が可能になる構成が示されているが、半円弧状フィンベースの円周側面に備えるとされる整流素子（ダイオード）の詳細についての説明が無く、その固定方法についても記載されていない。
例えば特許文献２の構成に特許文献１でも周知の半田付けを適用し実際の製品を得ようとすると、下記の問題が生じることが明らかである。
特許文献２ 第２図構成：
装着作業時にはフィン先端面あるいは固定端面が安定して下支え可能な構成であることが必要であるだけでなく、溶融した半田を保持する為に作業時にフィンベース面(ダイオード支持面)を水平状態とすることが必要である。装着するダイオード毎に、フィンベースのダイオード固定面を水平状態にする作業を繰り返さなければならない。
他の装着方法として、ダイオードをフィンベースに圧入することを考えた場合も同様で、荷重をかけて圧入することからも、フィンベースのダイオード固定面を水平状態に下支えする作業が各々必要となる。
つまりは、半円弧状のフィンベース（特許文献２）で構成する場合、実際にはダイオード装着時の該部背面の冷却フィン先端加工、削除、等の工夫や、個々に行う配置作業工程など、製造作業性は極端に悪く、量産化が困難とされていた。 The configuration described in Patent Document 2 shows a configuration that allows an increase in fin area, but there is no description of details of a rectifying element (diode) that is supposed to be provided on the circumferential side surface of the semicircular arc fin base. The fixing method is not described.
For example, it is apparent that the following problems occur when an actual product is obtained by applying soldering well known in Patent Document 1 to the configuration of Patent Document 2.
Patent Document 2 Fig. 2 Configuration:
It is not only necessary for the fin tip surface or fixed end surface to be able to support stably during mounting work, but the fin base surface (diode support surface) must be kept horizontal during work in order to hold molten solder. It is necessary to. For each diode to be mounted, the process of making the fin-based diode fixing surface horizontal must be repeated.
The same applies to the case where the diode is press-fitted into the fin base as another mounting method. The work of supporting the diode-fixing surface of the fin base in a horizontal state is also required from the press-fitting with a load. .
In other words, when configured with a semi-arc-shaped fin base (Patent Document 2), in actuality, such as the cooling fin tip processing and deletion of the rear surface of the part at the time of mounting the diode, the arrangement work process to be performed individually, etc. Manufacturability was extremely poor, and mass production was considered difficult.

上記の課題を解決するために、この発明では、弾性変形可能に構成された冷却部材の円弧状本体部から複数のフィンを延出させるとともに、前記円弧状本体部に整流素子を固定する固定溝部を設け、前記固定溝部を拡張する方向に変形させて該固定溝部に素子を配置後、変形を解く構成により、整流素子と前記冷却部材とを一体化するようにした。
In order to solve the above-described problems, in the present invention, a plurality of fins are extended from an arcuate body portion of a cooling member configured to be elastically deformable , and a fixing groove portion that fixes a rectifying element to the arcuate body portion The rectifying element and the cooling member are integrated by a configuration in which the fixed groove portion is deformed in the extending direction and an element is disposed in the fixed groove portion and then the deformation is released.

この発明によれば、困難であった複数の整流素子を円周側面に配置する事が出来るようになり、主に円筒形状の回転電気機器内に合わせて、余剰空間無く効率良く整流装置を配置出来るようになるだけでなく、複数の整流素子を同時に円弧状周側面に配置することができる。これにより回転電機の小型がはかられ、材料コスト、製造コストが低減出来る。
且つ、整流素子固定部直下に配した冷却フィンを、円筒状の回転電気機器の軸線に向くように、冷却流体がフィン間を通って軸端へ抜けるように、配置することができる為、回転電気機器内の軸方向の冷却流体による冷却効果が向上し、整流装置の信頼性が上がるとともに整流装置の寿命が延びるという効果がある。 According to the present invention, a plurality of rectifying elements that have been difficult can be arranged on the circumferential side surface, and the rectifying device is efficiently arranged without excess space mainly in a cylindrical rotary electric device. In addition to being able to do so, a plurality of rectifying elements can be simultaneously arranged on the arcuate peripheral side. As a result, the rotating electrical machine can be reduced in size, and material costs and manufacturing costs can be reduced.
In addition, the cooling fins arranged directly under the rectifying element fixing part can be arranged so that the cooling fluid passes through the fins and goes to the shaft end so as to face the axis of the cylindrical rotating electric device. The cooling effect by the axial cooling fluid in the electrical equipment is improved, and there is an effect that the reliability of the rectifier increases and the life of the rectifier extends.

以下、この発明の実施の形態について、添付図面を参照して説明する。
実施の形態１．
図１は、この発明を適用した車両用交流発電機の要部断面図、図２はその冷却部材への整流素子の固定方法の一例を模式的に示す平面図である。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
Embodiment 1 FIG.
FIG. 1 is a cross-sectional view of an essential part of an automotive alternator to which the present invention is applied, and FIG. 2 is a plan view schematically showing an example of a method of fixing a rectifying element to the cooling member.

先ず、車両用交流発電機の全体構造を図１に基づいて説明する。構成部品をその内側に取り囲んで支承するケーシング２の中には、回転子３が配置されている。この回転子３の外周には、一対のポールコア３１、３２の爪状磁極と僅かな間隔を介して固定子４が配置され、さらに上記回転子３が備えるシャフト３３にはプーリが設けられ、ベルト(図示せず)により回転駆動できるように構成されている。また、ポールコア３１、３２の内部には、両ポールコアを異なる磁極に励磁するための界磁巻線３４が装着され、ポールコア３１、３２の外部には、冷却手段としての冷却ファン３５が取り付けられている。   First, the overall structure of the vehicle alternator will be described with reference to FIG. A rotor 3 is arranged in a casing 2 that surrounds and supports the components inside. On the outer periphery of the rotor 3, the stator 4 is disposed with a small distance from the claw-shaped magnetic poles of the pair of pole cores 31 and 32. Further, the shaft 33 provided in the rotor 3 is provided with a pulley, and the belt (Not shown) is configured to be rotationally driven. Further, a field winding 34 for exciting both pole cores to different magnetic poles is mounted inside the pole cores 31 and 32, and a cooling fan 35 as a cooling means is attached to the outside of the pole cores 31 and 32. Yes.

更に、シャフト３３の一端にはスリップリング５が設けられ、界磁巻線３４と電気的に接続されており、このスリップリング５及びブラシ（図示せず）を介して外部から電流が供給されるようになっている。またケーシング２が支承する構成部品として、前記界磁巻線３４に電流が供給され回転駆動されて生じる回転磁界により固定子４の巻線４１に発生する交流の起電力を、直流に整流する整流装置６と、その発生した電力を規定値に制限する電圧調整器（図示せず）とが配置される。   Further, a slip ring 5 is provided at one end of the shaft 33, and is electrically connected to the field winding 34, and current is supplied from the outside through the slip ring 5 and a brush (not shown). It is like that. Further, as a component supported by the casing 2, rectification is performed to rectify an alternating electromotive force generated in the winding 41 of the stator 4 by a rotating magnetic field generated when a current is supplied to the field winding 34 and rotationally driven. A device 6 and a voltage regulator (not shown) for limiting the generated power to a specified value are arranged.

次いで、整流装置６について説明する。正極側冷却部材６１は、フィン６３を内周方向に突出させて配置し、負極側冷却部材７１はフィン７３を外周方向に突出させて配置され、そのフィンの反対側の対向面には、それぞれ正極側整流素子６５、負極側整流素子７５が配置される。フィン６３、７３は、冷却効率を上げるよう冷却ファン３５によって生じる冷却風の流れに沿って、複数隣接して設けられている。上記複数の正極側整流素子６５、負極側整流素子７５の引出端子と、固定子巻線４１のリード４２とを電気的に接続する端子台８が整流装置６と固定子４との間に配置されている。   Next, the rectifier 6 will be described. The positive side cooling member 61 is disposed with the fins 63 protruding in the inner circumferential direction, and the negative side cooling member 71 is disposed with the fins 73 protruding in the outer peripheral direction. A positive electrode side rectifying element 65 and a negative electrode side rectifying element 75 are arranged. A plurality of fins 63 and 73 are provided adjacent to each other along the flow of cooling air generated by the cooling fan 35 so as to increase the cooling efficiency. A terminal block 8 that electrically connects the lead terminals of the plurality of positive-side rectifying elements 65 and negative-side rectifying elements 75 and the leads 42 of the stator winding 41 is disposed between the rectifying device 6 and the stator 4. Has been.

上記整流素子、放熱フィンを備えた冷却部材の構成を、組立の順を追って図２により説明する。
正極側冷却部材６１はベース部６２が略円弧形状にされ、その中心軸側に面する側面に、中心軸に向かって延びる複数のフィン６３が設けられ、ベース部のフィン６３が設けられた反対側には複数の固定溝部６４が形成されている。 The structure of the cooling member provided with the rectifying element and the heat radiating fin will be described with reference to FIG.
The positive-side cooling member 61 has a base portion 62 having a substantially arc shape, and a plurality of fins 63 extending toward the central axis are provided on the side surface facing the central axis side, and the base portion fins 63 are provided. A plurality of fixed groove portions 64 are formed on the side.

図２は冷却部材への整流素子の固定方法を説明する図である。
正極側冷却部材６１は、フィン面積を確保する為、ベース部６２を半円弧形状にし、軸方向の風の流れを妨げないように径方向に多数の冷却フィン６３を形成している。冷却部材ベース部６２のフィン６３に対向する背面には正極側整流素子６５を取り付ける為、奥に行くに従い広くなるテーパを設けた固定溝部６４を設けている（図２（ａ））。
なお、この固定溝部６４の開口幅は整流素子６５のベース６６幅より小さく決められている。 FIG. 2 is a diagram illustrating a method of fixing the rectifying element to the cooling member.
The positive-side cooling member 61 has a semicircular arc shape in the base portion 62 in order to secure a fin area, and a large number of cooling fins 63 are formed in the radial direction so as not to hinder axial wind flow. In order to attach the positive-side rectifying element 65 to the back surface of the cooling member base portion 62 facing the fins 63, a fixed groove portion 64 having a taper that becomes wider toward the back is provided (FIG. 2A).
The opening width of the fixed groove portion 64 is determined to be smaller than the base 66 width of the rectifying element 65.

まず、固定溝部６４に整流素子６５のベースを挿入する為、冷却部材６１先端に図２（ｂ）のように内径方向に荷重を作用させ、冷却部材６１を弾性変形させてやることで固定溝部６４の開口幅を整流素子６５ベース幅より広げて、整流素子ベース６６を固定溝部６４に配置する（図２（ｃ））。このときの挿入方向は径方向・軸方向のどちらでも可能である。   First, in order to insert the base of the rectifying element 65 into the fixed groove portion 64, a load is applied to the tip of the cooling member 61 in the inner diameter direction as shown in FIG. The rectifying element base 66 is disposed in the fixed groove portion 64 with the opening width of 64 wider than the rectifying element 65 base width (FIG. 2C). The insertion direction at this time can be either radial or axial.

次いで、整流素子ベース６６を固定溝部６４に配置した状態で、冷却部材６１に作用させている荷重を除荷してやることで、固定溝部６４の開口幅は初期の状態（図２（ａ））近くまで戻り、整流素子ベース６６は固定溝部６４で固定され、冷却フィン６３を備えた冷却部材６１と整流素子６５は一体化される。   Next, with the rectifying element base 66 disposed in the fixed groove portion 64, by removing the load applied to the cooling member 61, the opening width of the fixed groove portion 64 is close to the initial state (FIG. 2A). The rectifying element base 66 is fixed by the fixing groove portion 64, and the cooling member 61 including the cooling fins 63 and the rectifying element 65 are integrated.

なお、整流素子ベース６６の冷却部材６１への固定がされれば良いので、整流素子６５取り付け前の状態（図２(ａ)）の内寸法Ａと、整流素子６５取り付け後の状態（図２（ｄ））の内寸法Ｂが厳密にまったく同一寸法である必要は無く、整流装置として車両用交流発電機に組み込む際に支障がない範囲で寸法の大小は可能である。実際では寸法Ａを寸法Ｂよりわずかに大きく設けることで、整流素子ベース６６を挿入後の冷却部材ベース部６２の変形を考慮した構成が得られる。   Since the rectifying element base 66 only needs to be fixed to the cooling member 61, the internal dimension A before the rectifying element 65 is attached (FIG. 2A) and the state after the rectifying element 65 is attached (FIG. 2). The inner dimension B of (d)) does not have to be exactly the same dimension, and the size can be increased or decreased within a range that does not hinder the incorporation as a rectifier in a vehicle AC generator. Actually, by providing the dimension A slightly larger than the dimension B, it is possible to obtain a configuration that takes into account the deformation of the cooling member base part 62 after the rectifying element base 66 is inserted.

なお、図２の説明では、冷却部材ベース部への荷重例として先端部周辺に円弧状矢印６７や直線状矢印６８を示したが、これに限定するもので無く、その所望変形度合いや冷却部材ベース形状を加味した荷重例が適宜選択可能である。また、場合によっては、図示しない冶具で整流素子６５の固定溝部６４以外の箇所を保持しながら荷重を作用させても良い。このようにすれば、作業時間は増大するが、個々の整流素子ごとに確実に取付けが行える。   In the description of FIG. 2, the arc-shaped arrow 67 and the linear arrow 68 are shown around the tip as an example of the load on the cooling member base, but the present invention is not limited to this, and the desired degree of deformation and the cooling member Examples of loads that take into account the base shape can be selected as appropriate. In some cases, a load may be applied while holding a portion other than the fixed groove portion 64 of the rectifying element 65 with a jig (not shown). In this way, the working time increases, but it is possible to reliably attach each individual rectifying element.

また、上述の説明では固定用の固定溝部６４を奥が広くなるテーパ状とし、整流素子ベース６６をこれに合うよう同様にテーパ状に構成したが、双方が固定できるようであればそれぞれが非テーパ状に構成されるものであっても適用可能である。
実施の形態２． Further, in the above description, the fixing groove 64 for fixing is tapered so that the depth is wide, and the rectifying element base 66 is similarly tapered so as to match it. Even those configured in a tapered shape are applicable.
Embodiment 2. FIG.

図３は負極側冷却部材７１への負極側整流素子７５の固定方法を説明する図である。図２と異なるのは、フィン７３が外径側、固定溝部７４が内径側に配してあり、冷却部材ベース部７２先端に図３（ｂ）のように外径方向に荷重（円弧状矢印７７や直線状矢印７８）を作用させ、弾性変形させてやることで固定溝部７４開口幅を整流素子ベース幅７６より広げている。その他は図２の場合と同様である。固定溝部７４への整流素子ベース７６挿入前後の冷却部材の寸法については、挿入前（図３（ａ））の内寸法Ｃは、挿入後(図３（ｄ）)の内寸法Ｄよりわずかに小さくするとよい。   FIG. 3 is a view for explaining a method of fixing the negative electrode side rectifying element 75 to the negative electrode side cooling member 71. The difference from FIG. 2 is that the fin 73 is arranged on the outer diameter side and the fixed groove 74 is arranged on the inner diameter side, and the load (arc-shaped arrow) is applied to the distal end of the cooling member base 72 in the outer diameter direction as shown in FIG. 77 and the linear arrow 78) are applied and elastically deformed to widen the opening width of the fixed groove 74 from the rectifying element base width 76. Others are the same as the case of FIG. Regarding the dimensions of the cooling member before and after the rectifying element base 76 is inserted into the fixed groove 74, the inner dimension C before insertion (FIG. 3A) is slightly smaller than the inner dimension D after insertion (FIG. 3D). It is better to make it smaller.

なお、実施の形態１、実施の形態２いずれにおいても固定溝の形状を変えることで、円筒形状の整流素子及びその他の形状の素子にも対応可能である。
また、冷却部材ベース部から突出させるフィンが内径方向であるか外径方向であるかは、適宜選択する構成であり、正極側負極側がいずれであっても良いことは言うまでもない。 Note that both the first and second embodiments can be applied to cylindrical rectifying elements and other elements by changing the shape of the fixing groove.
Moreover, it is a structure which selects suitably whether the fin protruded from a cooling member base part is an internal-diameter direction or an outer-diameter direction, and it cannot be overemphasized that any may be sufficient as the positive electrode side negative electrode side.
