Description

本発明は、各種装置の電気回路に用いられるリアクトルを構成するリアクトル用ボビン、このリアクトル用ボビンを用いたリアクトル、およびこのリアクトルの製造方法に関するものである。 The present invention relates to a reactor bobbin constituting a reactor used in electric circuits of various devices, a reactor using the reactor bobbin, and a method for manufacturing the reactor.

リアクトルは、電線を巻回して構成されたコイルと、このコイルの空芯部に挿通される中空筒状のリアクトル用ボビンと、リアクトル用ボビンの内側中空部に脚部が挿通される磁性コアとを備えて構成されており、リアクトル用ボビンを絶縁材料で構成することでコイルと磁性コアとの間の絶縁をとるようにしている。リアクトル用ボビンとしては、筒体をその軸方向の所定の位置で2つに分割した形状に形成されたボビン構成部材の各々を、コイル巻回体の中空部に挿通した状態で組み合わせて筒構造を形成するものが提案されている(例えば、特許文献1および特許文献2参照)。 The reactor includes a coil formed by winding an electric wire, a hollow cylindrical reactor bobbin that is inserted through the air core of the coil, and a magnetic core that has legs inserted into the inner hollow portion of the reactor bobbin. The coil and the magnetic core are insulated by forming the reactor bobbin from an insulating material. As a bobbin for a reactor, each of the bobbin constituent members formed in a shape in which a cylindrical body is divided into two at a predetermined position in the axial direction is inserted into the hollow portion of the coil winding body and combined to form a cylindrical structure. (see, for example, Patent Documents 1 and 2).

特開2011-198847号公報JP 2011-198847 A 特開2012-070001号公報Japanese Unexamined Patent Application Publication No. 2012-070001

ところで、上記特許文献に記載のリアクトル用ボビンは、組立作業において、両端部に鍔部をそれぞれ設けた2つのボビン構成部材を連結する作業をコイルの空芯部内で行うことが必要である。このとき、連結部分がコイルの外側から殆ど見えないので、作業に困難性を伴う。また、各鍔部が各ボビン構成部材に固定されており、鍔部間の距離、言い換えるとコイルが巻回状態に配置される際の空間の大きさを変更することができない。このため、コイルの長さが設計上の公差の範囲内に収まっていたとしても、鍔部間の距離が狭すぎてコイルが配置できなかったり、あるいは、鍔部に過大な負荷が掛かったり、鍔部間の距離が広すぎてコイルがガタついてしまったりする虞がある。さらに、ターン数等の仕様変更のためにコイルの設計上の長さが変更になると、リアクトル用ボビンも併せて設計・製造し直すことが必要となる場合がある。 By the way, in the assembly work of the reactor bobbin described in the above patent document, it is necessary to perform the work of connecting the two bobbin constituent members each provided with a flange portion at each end in the air core portion of the coil. At this time, since the connecting portion is hardly visible from the outside of the coil, the work is difficult. In addition, since each collar is fixed to each bobbin component, it is not possible to change the distance between the collars, in other words, the size of the space when the coil is arranged in a wound state. For this reason, even if the length of the coil is within the design tolerance range, the distance between the flanges is too narrow to allow the coil to be placed, or the flanges may be overloaded. If the distance between the flanges is too wide, there is a risk that the coil will rattle. Furthermore, if the design length of the coil is changed due to a change in the number of turns or other specifications, it may be necessary to redesign and manufacture the reactor bobbin as well.

特に、平角線を使用し巻回してなるエッジワイズコイルにおいては、巻線が1層であるため、このエッジワイズコイルを巻回状態に装着するリアクトル用ボビンのコイル装着部の長さは、電線の厚み公差(例:±0.13mm×巻数)を考慮して大きく作成することになる。この場合、上記ボビンとコイルの間は、ワニス等が充填されてコイルが固定されるが、エッジワイズコイルは空芯であるため、コイル長と上記コイル装着部の長さの差が大きい場合には、振動等によりコイルの固定が外れて製品上および性能上の種々の不具合が生起することになる。 In particular, an edgewise coil formed by winding a rectangular wire has a single layer of winding. Considering the thickness tolerance (eg ± 0.13mm x number of turns), it will be made large. In this case, the space between the bobbin and the coil is filled with varnish or the like to fix the coil. Otherwise, the coil may become unfixed due to vibration or the like, causing various defects in terms of product and performance.

本発明は、上記のような事情に鑑みてなされたもので、コイルの装着性を改善する一方、コイルが巻回状態に装着される空間をコイルの寸法に応じて調整し得るリアクトル用ボビン、このリアクトル用ボビンを適用したリアクトル、および、このリアクトルの製造方法を提供することを目的とするものである。 The present invention has been made in view of the above circumstances, and provides a reactor bobbin capable of improving mountability of the coil and adjusting the space in which the coil is mounted in a wound state according to the dimensions of the coil. An object of the present invention is to provide a reactor to which this reactor bobbin is applied, and a method for manufacturing this reactor.

Among them, the open portion (between the tip of the second piece 1222 and the tip of the third piece 1223) is used as a fitting inlet 122B and communicates with the fitting cavity 122A, and the body 121A of the bobbin 120 is the fitting inlet. It is configured to fit into the fitting cavity 122A through 122B (see FIG. 3(b)). In addition, the opening edge of the fitting cavity 122A (the inner edge of the mounting flange 122 composed of the inner edges of the first piece 1221 to the third piece 1223) is used as the engaging part 122C, and the fitting cavity 122A When the trunk portion 121A is fitted, the engaging portion 122C engages with the trunk portion 121A side (specifically, the outer peripheral surface of the trunk portion 121A).

前記胴部121Aの他端部(装着鍔部122が装着される他端部)の外周面には、係合部122Cが係合する係合受部121Cを備えている。具体的には、断面矩形状の溝で構成された係合受部121Cを胴部121Aの周方向(軸方向とは直交する方向)へ延在する態様で、固定鍔部121Bと平行に設定されている。さらに、複数条(本実施形態では4条)の係合受部121Cを等間隔で胴部121Aの軸方向へずらした状態で並べて形成し、固定鍔部121Bとの離間距離を係合受部121C毎に異ならせている。なお、本実施形態では、胴部121Aの他端部の外周面のうち丸み処理が施された隅角部分の一部には溝状の係合受部121Cが形成されていないが、胴部121Aの他端部の外周面の全周に亘って係合受部121Cを連続して形成してもよい。 An engagement receiving portion 121C with which an engaging portion 122C engages is provided on the outer peripheral surface of the other end portion (the other end portion to which the mounting collar portion 122 is attached) of the body portion 121A. Specifically, the engagement receiving portion 121C formed of a groove having a rectangular cross section is set parallel to the fixed collar portion 121B in a manner extending in the circumferential direction (direction orthogonal to the axial direction) of the trunk portion 121A. It is Furthermore, a plurality of (four in the present embodiment) engagement receiving portions 121C are arranged at equal intervals in a state of being shifted in the axial direction of the trunk portion 121A, and the separation distance from the fixed collar portion 121B is set to the engagement receiving portion. 121C. In this embodiment, the groove-shaped engagement receiving portion 121C is not formed in part of the rounded corner portion of the outer peripheral surface of the other end portion of the trunk portion 121A. The engagement receiving portion 121C may be formed continuously over the entire circumference of the outer peripheral surface of the other end portion of 121A.

さらに、リアクトル用ボビン120においては、係合部122Cと係合受部121Cとの係合状態を維持可能な係合ストッパー122Dを備えている。係合ストッパー122Dは、図3(b)に示すように、嵌合入口122Bの両側方に一対の突起を嵌合入口122B側へ突設して構成されており、装着鍔部122と同じ板厚寸法、さらには、係合部122C(装着鍔部122の内側縁部)と同じ板厚寸法に設定されている。 Further, the reactor bobbin 120 includes an engagement stopper 122D capable of maintaining the engagement state between the engagement portion 122C and the engagement receiving portion 121C. As shown in FIG. 3B, the engagement stopper 122D has a pair of protrusions protruding from both sides of the fitting inlet 122B toward the fitting inlet 122B. It is set to have the same thickness dimension as that of the engaging portion 122C (the inner edge portion of the attachment collar portion 122).

図1、図2に示す一対のボビン120が並列に隣接配置された態様において、それぞれの胴部121Aの一端部に固定鍔部121Bが固定配設され、この胴部121Aの他端からそれぞれコイル100を装着する。その後、このコイル100から突出している上記胴部121Aの他端部にそれぞれ装着鍔部122を取り付けるものであるが、その装着方向が隣接側から装着するように構成されている。つまり、図2に示すように、両胴部121Aにそれぞれ反対側となる横方向から装着鍔部122を取り付け、磁性コア130の脚部132と組み付ける場合に、隣接するボビン120で装着鍔部122のそれぞれの縦方向の第1片1221の背部が近接するように配設する(図1参照)。これにより、作製されたリアクトル100においては、組み付けられた装着鍔部122は取り外し不能となっている。 1 and 2, in which the pair of bobbins 120 are arranged in parallel and adjacent to each other, a fixed collar portion 121B is fixedly provided at one end of each body portion 121A, and a coil is connected from the other end of the body portion 121A. Wear 100. After that, the mounting flanges 122 are attached to the other end portions of the body portion 121A protruding from the coil 100, and the mounting direction is configured to be mounted from the adjacent side. That is, as shown in FIG. 2, when the mounting flanges 122 are attached to the body portions 121A from the opposite lateral direction and assembled with the leg portions 132 of the magnetic core 130, the mounting flanges 122 are attached to the adjacent bobbins 120. are arranged such that the backs of the respective longitudinal first pieces 1221 of the are adjacent to each other (see FIG. 1). As a result, in the manufactured reactor 100, the attached mounting collar portion 122 cannot be removed.

次に、リアクトル100の製造方法について説明する。
リアクトル100の製造においては、リアクトル100の各構成部品を形成する工程と、各構成部品を用いてリアクトル100を組み立てる工程とを行う。リアクトル100の構成部品の形成工程においては、ボビン本体部121および装着鍔部122を射出成型等により別個に形成し(ボビン形成工程)、平角線材(電線)をエッジワイズ巻きしてコイル110を形成し(コイル形成工程)、圧粉成型、金属ブロックを切削する、あるいは、金属板を積層する等してU型コアブロック131を形成する(コアブロック形成工程)。
Next, a method for manufacturing reactor 100 will be described.
In manufacturing reactor 100, a process of forming each component of reactor 100 and a process of assembling reactor 100 using each component are performed. In the process of forming the components of the reactor 100, the bobbin main body 121 and the mounting flange 122 are separately formed by injection molding or the like (bobbin forming process), and the coil 110 is formed by edgewise winding a rectangular wire (electric wire). (coil forming step), and then compacting, cutting a metal block, or laminating metal plates to form a U-shaped core block 131 (core block forming step).

リアクトル100の各構成部品を形成したならば、一対のボビン本体部121、一対の装着鍔部122、一対のコイル110、一対のコアブロック131を用いてリアクトル100の組み立て工程を行う。まず、図4(a)に示すように、各コイル110に対して、空芯部111にボビン本体部121の胴部121Aを該胴部121Aの他端部(装着鍔部122が未装着状態の他端部)からそれぞれ挿通して胴部121Aの周りつまりコイル装着部にコイル110を取り付ける(コイル取付工程)。さらに、固定鍔部121Bにコイル110の一端部を当て、コイル110の他端部から胴部121Aの他端部を突出させて係合受部121Cを外方へ露出させる。 After the components of the reactor 100 are formed, the reactor 100 is assembled using the pair of bobbin main bodies 121 , the pair of mounting flanges 122 , the pair of coils 110 and the pair of core blocks 131 . First, as shown in FIG. 4( a ), for each coil 110 , the body 121 A of the bobbin main body 121 is attached to the air core 111 to the other end of the body 121 A (the mounting flange 122 is in an unmounted state). ) and attach the coil 110 around the body portion 121A, that is, around the coil attachment portion (coil attachment step). Furthermore, one end of the coil 110 is brought into contact with the fixed flange 121B, and the other end of the body 121A is protruded from the other end of the coil 110 to expose the engagement receiving portion 121C to the outside.

コイル110をボビン本体部121へ取り付けたならば、各胴部121Aの他端部(係合受部121Cが備えられた端部)に装着鍔部122をそれぞれ装着する(鍔部装着工程)。詳しくは、図4(b)に示すように、ボビン本体部121に対して、装着鍔部122を嵌合入口122Bが胴部121Aに対向した姿勢であり、且つ固定鍔部121Bと平行な姿勢に設定し、装着鍔部122を撓ませて嵌合入口122Bを広げる。そして、係合ストッパー122D同士の間隔が胴部121Aを嵌合し得る状態まで広がったならば、この状態で嵌合入口122Bを胴部121Aへ近づけて装着鍔部122を胴部121Aの他端部へ嵌合する。このとき、複数の係合受部121Cのうち、装着鍔部122がコイル110の他端部に当接する位置、あるいは、コイル110の他端部に最も近づく位置で係合部122Cが係合可能となる係合受部121Cを選択し、この選択した係合受部121Cに係合部122Cを近づける。そして、胴部121Aに装着鍔部122を十分に嵌合して胴部121Aが嵌合空部122A内に配置されると、係合ストッパー122Dが胴部121Aの外周面上を通過して外周面から外れて装着鍔部122の撓みが解除され、係合部122Cが係合受部121Cに係合し、係合ストッパー122Dが胴部121Aの隅部分に引っ掛かる。この結果、一対のリアクトル用ボビン120の各胴部121Aの周りにコイル110をそれぞれ巻回した状態となり、さらには、係合部122Cと係合受部121Cとが互いの係合位置を選択して係合したことにより、固定鍔部121Bと装着鍔部122との間隔がコイル110の実際の寸法に合わせて調整された状態となる。 After the coil 110 is attached to the bobbin main body 121, the mounting flange 122 is attached to the other end of each body 121A (the end provided with the engagement receiving portion 121C) (flange attachment step). More specifically, as shown in FIG. 4(b), the fitting inlet 122B of the mounting collar portion 122 is in a posture facing the body portion 121A with respect to the bobbin main body portion 121, and is parallel to the fixed collar portion 121B. , and the fitting opening 122B is widened by bending the mounting flange 122. As shown in FIG. Then, when the interval between the engagement stoppers 122D is widened to a state where the trunk portion 121A can be fitted, in this state, the fitting inlet 122B is brought closer to the trunk portion 121A, and the mounting collar portion 122 is moved to the other end of the trunk portion 121A. fit into the part. At this time, among the plurality of engagement receiving portions 121C, the engaging portion 122C can be engaged at a position where the mounting collar portion 122 contacts the other end portion of the coil 110 or at a position closest to the other end portion of the coil 110. is selected, and the engaging portion 122C is brought close to the selected engagement receiving portion 121C. Then, when the mounting collar portion 122 is sufficiently fitted to the trunk portion 121A and the trunk portion 121A is arranged in the fitting hollow portion 122A, the engagement stopper 122D passes over the outer peripheral surface of the trunk portion 121A to reach the outer circumference. Deflection of the mounting flange 122 is released by being out of the plane, the engaging portion 122C engages with the engaging receiving portion 121C, and the engaging stopper 122D is hooked on the corner portion of the trunk portion 121A. As a result, the coils 110 are respectively wound around the body portions 121A of the pair of reactor bobbins 120, and furthermore, the engaging portions 122C and the engaging receiving portions 121C select the mutual engaging positions. As a result, the gap between the fixed flange portion 121B and the mounting flange portion 122 is adjusted according to the actual dimensions of the coil 110. As shown in FIG.

リアクトル用ボビン120にコイル110を取り付けた後、胴部121Aの中空部に両側から一対の磁性コア130の各脚部132を挿入し収納する(コア組付工程)。詳しくは、図4(c)に示すように、コイル110が取り付けられた一対のリアクトル用ボビン120を胴部121Aの軸方向とは直交する方向に並べ、各胴部121Aの中空部の一端部に一方のU型コアブロック131の脚部132をそれぞれ挿入し、胴部121Aの中空部の他端部には他方のU型コアブロック131の脚部132をそれぞれ挿入する。さらに、胴部121Aの中空部内で脚部132の先端同士を接着剤等を用いて接合すると、環状の磁性コア130が形成され、磁性コア130の一部が胴部121A(リアクトル用ボビン120)の中空部に収納された状態となる。 After the coil 110 is attached to the reactor bobbin 120, the leg portions 132 of the pair of magnetic cores 130 are inserted from both sides into the hollow portion of the body portion 121A (core assembly step). Specifically, as shown in FIG. 4(c), a pair of reactor bobbins 120 to which the coil 110 is attached are arranged in a direction perpendicular to the axial direction of the trunk portion 121A, and one end portion of the hollow portion of each trunk portion 121A is arranged. The leg portions 132 of one U-shaped core block 131 are inserted into the hollow portion of the body portion 121A, and the leg portions 132 of the other U-shaped core block 131 are inserted into the other end portion of the hollow portion of the trunk portion 121A. Furthermore, when the ends of the leg portions 132 are joined together using an adhesive or the like in the hollow portion of the trunk portion 121A, an annular magnetic core 130 is formed, and a portion of the magnetic core 130 becomes the trunk portion 121A (reactor bobbin 120). It is stored in the hollow part of the

その後、各コイル110の表面にワニス等の液状絶縁材を塗布することによって、絶縁材を平角線材同士の隙間に含浸させたり、さらには、コイル(平角線材)110とリアクトル用ボビン120(胴部121A、固定鍔部121B、装着鍔部122)との間に充填させたりする。そして、絶縁材を固化させてコイル110の絶縁処理(表面処理)を行い、リアクトル100を完成させる。このとき、絶縁材が固化すると、コイル110とリアクトル用ボビン120とが絶縁材の介在により固着する。なお、コイル110の絶縁処理は、鍔部装着工程とコア組付工程との間に行ってもよい。 After that, by applying a liquid insulating material such as varnish to the surface of each coil 110, the gap between the rectangular wires is impregnated with the insulating material. 121A, fixed flange portion 121B, and mounting flange portion 122). Then, the insulating material is solidified to perform an insulation treatment (surface treatment) on the coil 110 to complete the reactor 100 . At this time, when the insulating material is solidified, the coil 110 and the reactor bobbin 120 are fixed to each other through the interposition of the insulating material. In addition, the insulation processing of the coil 110 may be performed between the flange attachment process and the core assembly process.

このようにして、ボビン本体部121に装着鍔部122を装着してリアクトル用ボビン120を構成し、このリアクトル用ボビン120をリアクトル100の構成部品に採用すれば、コイル110が巻回状態に設置される空間長(鍔部121B,122間の距離)をコイル110の寸法に応じて調整することができる。したがって、固定鍔部121Bと装着鍔部122間の距離が狭くてコイル110が配置できない、あるいは、力を加えてコイル110を設置して両鍔部121B,122に過大な負荷が掛かるという不都合や、逆にコイル110が設置できたとしても両鍔部121B,122間の距離がコイル長より広くてガタついてしまう不都合を抑制することができる。また、ワニス等の絶縁材によるコイル110と胴部121Aとの固着がコイル110の振動等の外力を受けて解かれてしまったとしても、寸法差を小さくできることでコイル110が大きくガタつくことを両鍔部121B,122によって防ぐことができる。 In this manner, the reactor bobbin 120 is configured by attaching the mounting collar portion 122 to the bobbin main body portion 121, and if this reactor bobbin 120 is employed as a component of the reactor 100, the coil 110 is installed in a wound state. The space length (the distance between the flanges 121B and 122) can be adjusted according to the dimensions of the coil 110. Therefore, the distance between the fixed flange portion 121B and the mounting flange portion 122 is too narrow to dispose the coil 110. Alternatively, the coil 110 may be installed by applying force to apply an excessive load to both the flange portions 121B and 122. Conversely, even if the coil 110 can be installed, it is possible to suppress the inconvenience that the distance between both flanges 121B and 122 is wider than the coil length and rattles. In addition, even if the adhesion between the coil 110 and the body portion 121A by an insulating material such as varnish is loosened by receiving an external force such as vibration of the coil 110, the reduction in the dimensional difference prevents the coil 110 from rattling. Both flanges 121B and 122 can prevent this.

また、複数の係合受部121Cを固定鍔部121Bからの位置が異なる状態で形成し、いずれかの係合受部121Cを選択して係合部122Cを係合すること(言い換えると、係合部122Cと係合受部121Cとが互いの係合位置を選択して係合すること)により、固定鍔部121Bと装着鍔部122との間隔を調整可能としたので、装着鍔部122が不用意にずれたり脱落したりしてしまうことを抑えることができる。さらに、係合部122Cと係合受部121Cとの係合位置を容易に選択することができ、装着鍔部122の位置決めを迅速に行うことができる。 In addition, a plurality of engagement receiving portions 121C are formed at different positions from the fixed collar portion 121B, and one of the engagement receiving portions 121C is selected to engage the engaging portion 122C (in other words, the engaging portion 122C is engaged). The joint portion 122C and the engagement receiving portion 121C engage with each other by selecting the engagement position, so that the distance between the fixed flange portion 121B and the mounting flange portion 122 can be adjusted. It is possible to suppress the accidental slippage or falling off. Furthermore, the engagement position between the engagement portion 122C and the engagement receiving portion 121C can be easily selected, and the mounting collar portion 122 can be quickly positioned.

そして、各係合受部121Cを胴部121Aの外周面に備えたので、装着鍔部122の装着作業(鍔部装着工程)において、装着鍔部122の係合部122Cを係合させる箇所を容易に視認することができる。このため、装着作業を滞りなく且つ確実に行い易くなり、作業効率の向上を図ることができる。また、係合部122Cと係合受部121Cとの係合状態を維持可能な係合ストッパー122Dを備えたので、装着鍔部122のずれや脱落を一層抑制することができる。さらに、上記した各工程(ボビン形成工程、コイル形成工程、コイル取付工程、鍔部装着工程、コア組付工程)を含む製造方法によってリアクトル100を製造するので、装着鍔部122が備えられたリアクトル用ボビン120とコイル110とを用いてリアクトル100の組み立てを支障なく行うことができ、リアクトル100の組立作業の容易化を図ることができる。 Since each engagement receiving portion 121C is provided on the outer peripheral surface of the body portion 121A, in the mounting operation of the mounting collar portion 122 (the collar portion mounting step), the engaging portions 122C of the mounting collar portion 122 are engaged with each other. It is easily visible. Therefore, the mounting work can be performed smoothly and reliably, and the work efficiency can be improved. Further, since the engagement stopper 122D capable of maintaining the engagement state between the engagement portion 122C and the engagement receiving portion 121C is provided, it is possible to further prevent the mounting collar portion 122 from slipping or coming off. Furthermore, since the reactor 100 is manufactured by the manufacturing method including the above-described steps (bobbin forming step, coil forming step, coil mounting step, flange mounting step, core assembling step), the reactor provided with the mounting flange 122 The assembly of the reactor 100 can be performed without any trouble by using the coil 110 and the coil 110, and the assembly work of the reactor 100 can be facilitated.

上記第1の実施形態におけるリアクトル用ボビン120は、隣接配置された一対のボビン120のそれぞれのボビン本体部121の胴部121Aの一端部に固定鍔部121Bを備えて構成されているが、本発明はこれに限定されない。例えば、図5に示す第2の実施形態のリアクトル用ボビン220は、基本的には第1の実施形態と同じであるが、ボビン本体部221に並設された一対の胴部221Aの一端部に固定される固定鍔部221Bまたは他端部に装着される装着鍔部223が一体に繋がって構成されている点で異なる。 The reactor bobbin 120 in the first embodiment is configured to include a fixed collar portion 121B at one end portion of the body portion 121A of the bobbin main body portion 121 of each of the pair of bobbins 120 arranged adjacent to each other. The invention is not so limited. For example, the reactor bobbin 220 of the second embodiment shown in FIG. The difference is that the fixed collar portion 221B fixed to the second end portion or the mounting collar portion 223 attached to the other end portion are integrally connected to each other.

具体的に説明すると、図5(a),(b)に示す第2の実施形態におけるリアクトル用ボビン220のボビン本体部221は、並列状態で配置された一対の胴部221Aを備え、各胴部221Aの一端部にそれぞれ配置される固定鍔部221Bが一体に連続して形成され、ボビン220の一対の胴部221Aの一端部同士を固定鍔部221Bで連結した構成となっている。また、各胴部221Aの他端部には、溝で構成された係合受部221Cを胴部221Aの軸方向に沿って等間隔で複数条(本実施形態では4条)並べて備え、各係合受部221Cと固定鍔部221Bとの離間距離を係合受部221C毎に異なる状態に設定している。この態様では構成部品数を減らすことができ、製造効率の向上を図ることができる。 Specifically, the bobbin main body 221 of the reactor bobbin 220 according to the second embodiment shown in FIGS. Fixed flange portions 221B arranged at one ends of the portions 221A are integrally formed continuously, and one end portions of the pair of body portions 221A of the bobbin 220 are connected to each other by the fixed flange portions 221B. At the other end of each trunk portion 221A, a plurality of grooved engagement receiving portions 221C (four in this embodiment) are arranged at regular intervals along the axial direction of the trunk portion 221A. The separation distance between the engagement receiving portion 221C and the fixed collar portion 221B is set to be different for each engagement receiving portion 221C. In this aspect, the number of components can be reduced, and the manufacturing efficiency can be improved.

また、図5(a)に示す形態では、各胴部221Aの他端部に、胴部221A毎に別個のC字状装着鍔部222を図の上方より装着して係合受部221Cと係合部222Cとを係合し、係合ストッパー222Dにより係合状態を維持可能としている。あるいは、図5(b)に示す形態では、ボビン本体部221の各胴部221Aの他端部に設置する装着鍔部223も一体化している。この一体化装着鍔部223は矩形状の平板に一対の嵌合空部223Aおよび一対の嵌合入口223Bを横並び状態で開設して構成され、該装着鍔部223を胴部221Aの他端部同士の間に架け渡す状態で装着して係合受部221Cと係合部223Cとを係合し、係合ストッパー223Dにより係合状態を維持可能としている。 In addition, in the form shown in FIG. 5(a), a separate C-shaped attachment flange 222 is attached to the other end of each trunk 221A from above for each trunk 221A to form an engagement receiving portion 221C. It engages with the engaging portion 222C, and the engaging state can be maintained by the engaging stopper 222D. Alternatively, in the form shown in FIG. 5(b), the mounting collar portion 223 installed at the other end portion of each trunk portion 221A of the bobbin body portion 221 is also integrated. The integrated mounting collar portion 223 is formed by opening a pair of fitting hollow portions 223A and a pair of fitting inlets 223B in a horizontal manner on a rectangular flat plate. The engagement receiving portion 221C and the engagement portion 223C are engaged by being mounted in a state of bridging between them, and the engagement state can be maintained by the engagement stopper 223D.

図5(a)の胴部221A毎に別個の装着鍔部222を装着する態様を採用すれば、コイル同士でターン数(巻き数)が互いに異なる設計、ひいては長さ寸法が異なる設計であったとしても、各コイルの長さ寸法に合わせて装着鍔部222の装着箇所を調整することができる。一方、図5(b)の装着鍔部223を胴部221A同士の間に架け渡して装着する態様を採用すれば、リアクトルの構成部品数を減らすことができる。また、一対の胴部221Aへの鍔装着作業を一度に行うことができ、製造効率の向上を図ることができる。 By adopting a mode in which a separate mounting flange 222 is mounted for each body 221A in FIG. However, it is possible to adjust the mounting position of the mounting flange 222 according to the length dimension of each coil. On the other hand, the number of components of the reactor can be reduced by adopting a mode in which the mounting collar portion 223 shown in FIG. In addition, the operation of attaching the flanges to the pair of trunk portions 221A can be performed at once, and the manufacturing efficiency can be improved.

図6に示す第3の実施形態は、三相交流に対応するリアクトル用ボビン320を示し、全体的には、図5(b)の形態と類似し、3つのコイルを備える態様である。この形態のリアクトル用ボビン320のボビン本体部321は、3つの胴部321Aを並列状態(各胴部321Aの軸方向とは直交する方向に並べた状態)で配置し、各胴部321Aの一端部を一体形成した固定鍔部321Bで連結して構成している。 The third embodiment shown in FIG. 6 shows a reactor bobbin 320 compatible with three-phase alternating current, and is generally similar to the form of FIG. 5(b) and has three coils. The bobbin main body portion 321 of the reactor bobbin 320 of this form has three trunk portions 321A arranged in parallel (a state in which the trunk portions 321A are arranged in a direction orthogonal to the axial direction of each trunk portion 321A), and one end of each trunk portion 321A The parts are connected by a fixed flange part 321B integrally formed.

また、図6において、各胴部321Aの他端部には、一体化された装着鍔部323が装着され、この装着鍔部323は、3つの嵌合空部323Aおよび3つの嵌合入口323Bが横並び状態で開設された平板状に形成されている。該装着鍔部323を架け渡す状態で各胴部321Aに装着して、係合受部321Cと係合部323Cとを係合し、係合ストッパー323Dにより係合状態を維持可能としている。なお、図5(a)の態様のように別個の装着鍔部(図示せず)を胴部321A毎に装着してもよい。 In FIG. 6, an integrated mounting flange 323 is attached to the other end of each body 321A. are formed in a flat plate shape opened in a horizontal state. The mounting collar portion 323 is mounted on each body portion 321A in a bridged state, the engagement receiving portion 321C and the engagement portion 323C are engaged, and the engagement state can be maintained by the engagement stopper 323D. In addition, you may mount|wear with a separate mounting|wearing collar part (not shown) for every trunk|drum 321A like the aspect of Fig.5 (a).

ところで、上記各実施形態では、矩形筒状を呈する胴部121A,221A,321Aの外周面の4面に溝状の係合受部121C,221C,321Cを形成したが、本発明はこれに限定されない。要は、胴部の外周面で係合部を係合可能であれば、係合受部が形成される範囲は問わない。例えば、矩形筒状の胴部の外周面においては、装着鍔部の内側の縁部(係合部)が対向し得る3面のうち1面以上を選択して溝状の係合受部を形成してもよいし、あるいは、胴部の外周面の隅角部にも溝状の係合受部を形成してもよい。また、円筒状の胴部を構成してもよく、装着鍔部が円弧状となる場合には、胴部の外周面のうち装着鍔部の内側の縁部(係合部)が対向し得る部分に溝状の係合受部を形成すればよく、必ずしも胴部の外周面の全周に亘って係合受部を形成する必要はない。 By the way, in each of the above-described embodiments, groove-like engagement receiving portions 121C, 221C, and 321C are formed on the four outer peripheral surfaces of the body portions 121A, 221A, and 321A having a rectangular tubular shape, but the present invention is limited to this. not. In short, as long as the engagement portion can be engaged with the outer peripheral surface of the trunk portion, the range in which the engagement receiving portion is formed does not matter. For example, on the outer peripheral surface of the rectangular cylindrical body, one or more of the three surfaces that the inner edge (engagement portion) of the mounting flange can face is selected to form a groove-shaped engagement receiving portion. Alternatively, a groove-like engagement receiving portion may be formed in the corner portion of the outer peripheral surface of the trunk portion. In addition, a cylindrical body may be configured, and when the mounting collar is arc-shaped, the inner edge (engagement portion) of the mounting collar of the outer peripheral surface of the body may face each other. A groove-like engagement receiving portion may be formed in a portion, and it is not necessary to form the engagement receiving portion over the entire circumference of the outer peripheral surface of the barrel.

さらに、上記各実施形態では、係合受部121C,221C,321Cを断面矩形状の溝で構成し、係合部122C,222C,223C,323Cの断面を矩形状としたが、本発明はこれに限定されない。要は、互いに係合可能であれば、係合部および係合受部の態様は問わない。 Furthermore, in each of the above-described embodiments, the engagement receiving portions 121C, 221C, and 321C are configured by grooves with rectangular cross sections, and the cross sections of the engaging portions 122C, 222C, 223C, and 323C are rectangular. is not limited to In short, as long as they can be engaged with each other, the form of the engaging portion and the engagement receiving portion does not matter.

例えば、図7の第4の実施形態に示すように、リアクトル用ボビン420において、係合受部421Cを断面V字状の溝で構成してボビン本体部421の胴部421Aに備え、係合部422Cを断面尖形状の突条で構成して装着鍔部422の嵌合空部422Aの開口縁部に備えてもよい。係合受部421Cを断面V字状の溝で構成すれば、断面矩形状の溝で構成する場合よりも係合受部421C同士のピッチを狭く設定し易くなり、装着鍔部422の装着位置の選択肢、ひいては固定鍔部421Bと装着鍔部422との離間距離の調整性が向上する。 For example, as shown in the fourth embodiment of FIG. 7, in a reactor bobbin 420, an engagement receiving portion 421C is configured by a groove having a V-shaped cross section and is provided in a body portion 421A of a bobbin main body portion 421 to engage. The portion 422</b>C may be formed of a ridge with a sharp cross section and provided at the opening edge of the fitting hollow portion 422</b>A of the attachment collar portion 422 . If the engagement receiving portion 421C is configured by a groove with a V-shaped cross section, it becomes easier to set the pitch between the engagement receiving portions 421C narrower than in the case of configuring by a groove with a rectangular cross section, and the mounting position of the mounting collar portion 422 is reduced. , and thus the adjustability of the separation distance between the fixed flange portion 421B and the mounting flange portion 422 is improved.

また、上記各実施形態では、胴部121A,221A,321Aに備えられた複数の係合受部121C,221C,321Cをそれぞれ溝構造とし、装着鍔部122,222,223,323に備えられた係合部122C,222C,223C,323Cを突条構造としたが、本発明はこれに限定されない。要は、互いの係合位置を選択して係合することにより、固定鍔部と装着鍔部との間隔を調整可能とする構成であれば、どのような態様の係合部および係合受部の組み合わせを採用してもよい。例えば、胴部の他端部の外周面に備えられる複数の係合受部をそれぞれ突条、あるいはピン状の突起で構成し、装着鍔部の嵌合空部の開口縁部に備えられる係合部を溝で構成してもよい。 Further, in each of the above-described embodiments, the plurality of engagement receiving portions 121C, 221C, and 321C provided in the trunk portions 121A, 221A, and 321A are respectively grooved structures, and the attachment flange portions 122, 222, 223, and 323 are provided with Although the engaging portions 122C, 222C, 223C, and 323C have a ridge structure, the present invention is not limited to this. In short, any form of engaging part and engagement receiving part can be used as long as the gap between the fixed flange part and the mounting flange part can be adjusted by selecting the engagement positions of each other and engaging with each other. A combination of parts may be employed. For example, a plurality of engagement receiving portions provided on the outer peripheral surface of the other end portion of the barrel may be configured by ridges or pin-shaped projections, and the engagement provided on the opening edge of the fitting hollow portion of the mounting flange. The joint portion may be configured as a groove.

さらに、上記各実施形態では、胴部121A,221A,321Aに備えられた係合受部121C,221C,321Cを固定鍔部121B,221B,321Bからの位置(離間距離)を異ならせて複数形成したが、本発明はこれに限定されない。要は、係合部と係合受部とにおいて、少なくとも一方が固定鍔部からの位置を異ならせて複数形成されていれば、その態様は問わない。例えば、装着鍔部の嵌合空部の開口縁部を装着鍔部の板厚方向(胴部の軸方向)に沿って拡張し、この拡張された縁部に溝状の係合受部を装着鍔部の板厚方向(胴部の軸方向)にずらして複数条備えてもよい。そして、係合受部が係合する胴部上の係合部を突条で構成するが、この突条の条数は1条でもよいし、あるいは、複数条の係合受部のピッチに合わせて胴部の軸方向にずらして並んだ複数条でもよい。しかしながら、胴部上の係合部を突条や突起等で構成して胴部の外周面から突出させると、コイル取付工程において、係合部(突条や突起等)がコイルの内周面に引っ掛かって組立作業を滞らせる虞がある。これに対し、胴部上の係合部を胴部の外周面から突出しない構成(外周面を凹ませて構成された溝や凹み等)にすれば、コイル取付工程において、胴部とコイルの内周面とが引っ掛かり難くなり、リアクトルの組立作業を滞りなく行い易くなるので、好適である。 Furthermore, in each of the above-described embodiments, a plurality of engagement receiving portions 121C, 221C, and 321C provided on the trunk portions 121A, 221A, and 321A are formed at different positions (separation distances) from the fixed collar portions 121B, 221B, and 321B. However, the invention is not limited to this. The point is that at least one of the engaging portion and the engagement receiving portion may be formed in a plurality of positions with different positions from the fixed collar portion. For example, the opening edge of the fitting cavity of the mounting flange is expanded along the thickness direction of the mounting flange (the axial direction of the body), and a groove-shaped engagement receiving portion is formed on the expanded edge. A plurality of streaks may be displaced in the plate thickness direction of the mounting flange (the axial direction of the body). The engagement portion on the trunk portion with which the engagement receiving portion is engaged is composed of a ridge. A plurality of streaks arranged in a line while being shifted in the axial direction of the trunk portion may also be used. However, if the engaging portion on the body portion is formed of a ridge or projection and protrudes from the outer peripheral surface of the body portion, the engaging portion (such as a ridge or projection) may be formed on the inner peripheral surface of the coil during the coil mounting process. There is a risk that the assembly work will be delayed by being caught in the On the other hand, if the engaging portion on the body is configured so as not to protrude from the outer peripheral surface of the body (such as a groove or recess formed by recessing the outer peripheral surface), the body and the coil can be easily attached in the coil mounting process. This is preferable because the inner peripheral surface is less likely to get caught, and the reactor assembly work can be performed smoothly.

また、上記各実施形態では、本発明における係合ストッパーとして突起構造の係合ストッパー122D,222D,223D,323Dを例示したが、本発明はこれに限定されない。要は、係合部と係合受部との係合状態を維持可能であれば、どのような構成の係合ストッパーを採用してもよい。
例えば、図8の第5の実施形態に示すように、リアクトル用ボビン520において、ボビン本体部521の胴部521Aの外周面に形成された凹部521Eと、装着鍔部522に突設された凸部522Eとにより係合ストッパーを構成し、凹部521Eと凸部522Eとの係合により係合受部521Cと係合部522Cとの係合状態(装着鍔部522の装着状態)を維持可能としてもよい。あるいは、装着鍔部の嵌合入口を閉成可能な短冊部材(図示せず)を係合ストッパーとして採用し、胴部に装着された装着鍔部の嵌合入口を係合ストッパー(短冊部材)で閉成することにより、係合部と係合受部との係合状態の維持、さらには装着鍔部の胴部からの脱落阻止を実現してもよい。
Further, in each of the above-described embodiments, the engagement stoppers 122D, 222D, 223D, and 323D having a projecting structure are illustrated as the engagement stoppers in the present invention, but the present invention is not limited to this. In short, as long as the engaging state between the engaging portion and the engagement receiving portion can be maintained, any configuration of the engagement stopper may be employed.
For example, as shown in the fifth embodiment of FIG. The portion 522E constitutes an engagement stopper, and the engagement state between the engagement receiving portion 521C and the engagement portion 522C (the mounting state of the mounting collar portion 522) can be maintained by the engagement between the concave portion 521E and the convex portion 522E. good too. Alternatively, a strip member (not shown) capable of closing the fitting inlet of the mounting flange is employed as an engagement stopper, and the fitting inlet of the mounting flange attached to the body is used as the engagement stopper (strip member). By closing with , it is possible to maintain the engagement state between the engaging portion and the engagement receiving portion, and further to prevent the mounting collar portion from falling off from the trunk portion.

さらに、上記各実施形態では、装着鍔部122,222,223,323を略C字状または略E字状等の単一部材で構成する旨を例示したが、本発明はこれに限定されない。要は、胴部の他端部に装着可能であれば、どのような構成の装着鍔部を採用してもよい。例えば、2つの略C字状の枠部材を向かい合わせて矩形枠状の装着鍔部を構成可能とし、鍔部装着工程においては、2つの枠部材の間に胴部を挟み、この状態で枠部材の端部同士を係合して胴部に装着鍔部を装着するように構成してもよい。 Furthermore, in each of the above-described embodiments, the mounting flanges 122, 222, 223, 323 are illustrated as being composed of a single member having a substantially C-shape, substantially an E-shape, or the like, but the present invention is not limited to this. In short, as long as it can be attached to the other end of the trunk, any configuration of attachment collar may be adopted. For example, two substantially C-shaped frame members can be opposed to each other to form a rectangular frame-shaped attachment flange. It may be configured such that the end portions of the member are engaged with each other to attach the attachment collar portion to the trunk portion.

また、上記各実施形態に記載のコイル110は、平角線材をエッジワイズ巻きで巻回して構成されているが、本発明はこれに限定されない。電線を巻回して構成されるコイルであれば、その態様は問わない。例えば、丸線(断面円形状の電線)を巻回して構成されるコイルを本発明のリアクトルやリアクトルの製造方法に適用してもよい。 In addition, although the coil 110 described in each of the above embodiments is configured by edgewise winding a rectangular wire, the present invention is not limited to this. As long as it is a coil formed by winding an electric wire, it may be of any form. For example, a coil formed by winding a round wire (an electric wire having a circular cross section) may be applied to the reactor and the reactor manufacturing method of the present invention.
