Description

本発明の実施形態は、アルミニウムの巻線を用いたリアクトルに関する。   Embodiments of the present invention relate to a reactor using aluminum windings.

近年、リアクトルの巻線として、銅線に較べて安価に構成できるアルミニウム線が用いられている。このようなリアクトルでは、アルミニウム線の端部を、例えば黄銅製の電気端子の一端の圧着部に固定している。この電気端子の他端にコネクタ付きの銅製リード線が溶接される。   In recent years, an aluminum wire that can be constructed at a lower cost than a copper wire is used as a winding of a reactor.

A copper lead wire with a connector is welded to the other end of the electrical terminal.

特開2010−74156号公報JP 2010-74156 A

リアクトルの電気端子にコネクタが設けられることで、電源などから延びるリード線に設けられるコネクタとの接続作業が容易になる。しかしながら、コネクタ同士の接続部分には、流せる電流値に限度がある。例えば、一般的な平形接続端子では、流せる電流の最大値が約25Aとなっている。さらに、大電流を流す場合は、太いリード線を用いなければならず、電気端子とリード線との接続部分の強度を向上させる必要がある。   By providing the connector on the electric terminal of the reactor, the connection work with the connector provided on the lead wire extending from the power source or the like is facilitated. However, there is a limit to the current value that can be applied to the connection part between the connectors. For example, in a general flat connection terminal, the maximum value of the current that can be passed is about 25A. Furthermore, when flowing a large current, a thick lead wire must be used, and it is necessary to improve the strength of the connection portion between the electrical terminal and the lead wire.

本発明の実施形態は、このような事情を考慮してなされたもので、リード線との接続部分に、大電流を流すことができ、かつ接続強度を向上させることができるリアクトルを提供することを目的とする。   Embodiments of the present invention have been made in consideration of such circumstances, and provide a reactor that can flow a large current to a connection portion with a lead wire and improve connection strength. With the goal.

本発明の実施形態に係るリアクトルは、鉄心と、アルミニウムで形成され、前記鉄心に巻き付けられる巻線と、前記巻線の端部が接続される巻線接続部が一端に設けられ、かつリード線が接続される棒状を成すリード線接続部が他端に設けられた接続端子と、重なり合う前記リード線接続部と前記リード線の周囲を覆った状態でかしめられ、かつ半田が隙間に充填される筒状を成すスリーブと、を備える。   A reactor according to an embodiment of the present invention includes an iron core, aluminum, a winding wound around the iron core, a winding connecting portion to which an end of the winding is connected, and a lead wire. The lead wire connecting portion is connected to the connecting terminal provided at the other end, and the lead wire connecting portion is overlapped with the lead wire connecting portion and the lead wire is covered, and the solder is filled in the gap. A sleeve having a cylindrical shape.

(第1実施形態)
以下、本実施形態を添付図面に基づいて説明する。まず、第1実施形態のリアクトルについて図1から図4を用いて説明する。以下、図2の紙面左側をリアクトルの正面側(前方側)として説明する。
(First embodiment)
Hereinafter, this embodiment is described based on an accompanying drawing. First, the reactor of 1st Embodiment is demonstrated using FIGS. 1-4. Hereinafter, the left side of FIG. 2 will be described as the front side (front side) of the reactor.

図1の符号1は、リアクトルである。このリアクトル1は、その巻線に流れる電流によって生じる磁場にエネルギーを蓄えることができる受動素子である。このリアクトル1は、空気調和機の室外機の電源側、所謂整流器における電流の入口側に設けられ、力率を向上させている。   Reference numeral 1 in FIG. 1 is a reactor. The reactor 1 is a passive element that can store energy in a magnetic field generated by a current flowing through the winding. The reactor 1 is provided on the power supply side of the outdoor unit of the air conditioner, that is, on the current inlet side of the so-called rectifier, and improves the power factor.

図1および図2に示すように、リアクトル1は、台座2を備える。この台座2は、四角形状を成す板材である。この台座2が、室外機の筐体3の内部の所定部位にネジを用いて強固に取り付けられる。   As shown in FIGS. 1 and 2, the reactor 1 includes a pedestal 2. This pedestal 2 is a plate material having a quadrangular shape. The pedestal 2 is firmly attached to a predetermined portion inside the casing 3 of the outdoor unit using screws.

また、台座2の上面には、鉄心4が溶接される。この鉄心4は、E字形状を成す第1コア5とI字形状を成す第2コア6とが、互いに溶接されることで形成される。鉄心4の中央部空間、すなわち第1コア5のE字状の中央の突出部7の周囲に巻線8が巻回され、巻回コイル9が形成される。   An iron core 4 is welded to the upper surface of the base 2. The iron core 4 is formed by welding a first core 5 having an E shape and a second core 6 having an I shape. A winding 8 is wound around the central space of the iron core 4, that is, around the E-shaped central protrusion 7 of the first core 5, thereby forming a winding coil 9.

この巻線8は、アルミニウム材で形成される。また、巻線8は、その表面にエナメル被膜が焼き付けられて、絶縁されている。なお、巻線8の端部は、電気的に導通可能なようにエナメル被膜が除去されている。巻線8の両端部は、巻回コイル9から正面側に導出されている。   The winding 8 is made of an aluminum material. Further, the winding 8 is insulated by baking an enamel film on the surface thereof. Note that the enamel film is removed from the end of the winding 8 so as to be electrically conductive. Both end portions of the winding 8 are led out from the winding coil 9 to the front side.

巻線8の端部には、それぞれに接続端子10が接続される。図2に示すように、これらの接続端子10は、上下方向に延びる長板状を成す板部11を備える。また、板部11の下部が側面視でJ字形状に屈曲されている。なお、J字の短部先端(図2中左側先端)となる、この屈曲された部分の正面側、つまり、接続端子10の一端である基端側の立ち上がり部分に巻線8の端部が接続される。各接続端子10は、1枚の薄板の黄銅材を打ち抜き、折曲することで形成される。   A connection terminal 10 is connected to each end of the winding 8. As shown in FIG. 2, these connection terminals 10 include a plate portion 11 having a long plate shape extending in the vertical direction. Moreover, the lower part of the board part 11 is bent by J shape by side view. It should be noted that the end portion of the winding 8 is at the front side of this bent portion, that is, the proximal end side that is one end of the connection terminal 10, which becomes the tip of the short portion of the J-shape (left side tip in FIG. 2). Connected. Each connection terminal 10 is formed by punching and bending a thin brass material.

また、接続端子10の一部は、短絡または外部との接触を防止するために絶縁紙12で覆われている。さらに、絶縁紙12は、硬度の高い樹脂製の絶縁材料を用いて薄いフィルム状に形成されており、絶縁紙12の巻回コイル9側の面が巻回コイル9に接着されている。この絶縁紙12を介して、接続端子10が巻回コイル9に固定される。なお、接続端子10が配置された部分は、絶縁紙12と同等の素材からなる絶縁カバー13で覆われる。絶縁カバー13は、絶縁機能を有する粘着テープなどでリアクトル1に固定される。   A part of the connection terminal 10 is covered with an insulating paper 12 to prevent a short circuit or contact with the outside. Further, the insulating paper 12 is formed in a thin film shape using a resin hard insulating material, and the surface of the insulating paper 12 on the side of the winding coil 9 is bonded to the winding coil 9. The connection terminal 10 is fixed to the winding coil 9 through the insulating paper 12. A portion where the connection terminal 10 is disposed is covered with an insulating cover 13 made of the same material as the insulating paper 12. The insulating cover 13 is fixed to the reactor 1 with an adhesive tape having an insulating function.

第1実施形態の2つの接続端子10は、同一構成である。これらの接続端子10は、左右横方向に並設される。なお、接続端子10の板部11の基端側であって、巻線8の端部が接続される部分を巻線接続部14と称する。また、接続端子10の巻回コイル9側となる板部11の他端の上端側(先端側)には、電源などから延びるリード線15(図4参照)が接続されるリード線接続部16が設けられる。   The two connection terminals 10 of the first embodiment have the same configuration. These connection terminals 10 are arranged side by side in the horizontal direction. A portion of the connection terminal 10 on the base end side of the plate portion 11 and to which the end portion of the winding 8 is connected is referred to as a winding connection portion 14. Further, a lead wire connecting portion 16 to which a lead wire 15 (see FIG. 4) extending from a power source or the like is connected to the upper end side (tip end side) of the other end of the plate portion 11 on the winding coil 9 side of the connection terminal 10. Is provided.

図3(A)は、接続端子10の正面図である。図3(B)は、接続端子10の側面図である。図3(C)は、図3(A)における接続端子10のC−C断面図である。以下、図3(B)の紙面左側を接続端子10の正面側(前方側)とし、図3(C)の紙面下側を接続端子10の正面側(前方側)として説明する。   FIG. 3A is a front view of the connection terminal 10. FIG. 3B is a side view of the connection terminal 10. FIG. 3C is a CC cross-sectional view of the connection terminal 10 in FIG. In the following description, the left side of FIG. 3B is the front side (front side) of the connection terminal 10 and the lower side of FIG. 3C is the front side (front side) of the connection terminal 10.

図3(A)および図3(B)に示すように、接続端子10の巻線接続部14には、巻線8の端部を保持する4つの保持片17が設けられる。なお、接続端子10において、保持片17の部分は、断面視でC字形状を成す(図3(C)参照)。   As shown in FIGS. 3A and 3B, the winding connection portion 14 of the connection terminal 10 is provided with four holding pieces 17 that hold the end of the winding 8. In addition, in the connection terminal 10, the part of the holding piece 17 comprises C shape by sectional view (refer FIG.3 (C)).

巻線接続部14は、保持片17が巻線8の端部を保持した状態で、前後方向から所定の工具により挟持され、かしめられる。つまり、巻線8の端部と巻線接続部14が圧着される。また、巻線8の端部と保持片17との隙間には、半田18が流し込まれる。つまり、巻線8の端部と保持片17との隙間に半田18が充填される。なお、巻線接続部14には、上下方向に並んだ3つの穴部19が形成されている。これらの穴部19にも、半田18が入り込む。   The winding connection portion 14 is clamped by a predetermined tool in the front-rear direction with the holding piece 17 holding the end of the winding 8. That is, the end of the winding 8 and the winding connection 14 are crimped. In addition, solder 18 is poured into the gap between the end of the winding 8 and the holding piece 17. That is, the solder 18 is filled in the gap between the end of the winding 8 and the holding piece 17. The winding connection portion 14 is formed with three hole portions 19 arranged in the vertical direction. Solder 18 also enters these holes 19.

巻線8の端部と巻線接続部14とを、かしめるとともに両部材の隙間に半田18が流し込まれることで、接続強度を向上させることができる。また、巻線8の材質が、柔らかいアルミニウムであっても強固に接続することができ、その信頼性を確保することができる。また、巻線8の端部と保持片17との隙間に半田18が介在することで、異種金属同士の接触で生じる電蝕を生じ難くすることができる。   The end portion of the winding 8 and the winding connection portion 14 are caulked and the solder 18 is poured into the gap between the two members, so that the connection strength can be improved. Further, even if the material of the winding 8 is soft aluminum, it can be firmly connected, and its reliability can be ensured. In addition, since the solder 18 is interposed in the gap between the end portion of the winding 8 and the holding piece 17, it is possible to make it difficult to generate electrolytic corrosion caused by contact between different metals.

図4(A)は、接続端子10の他端、すなわち、巻線接続部14と反対側の端部にリード線15を接続する前の状態を示す。図4(B)は、接続端子10にリード線15を接続した後の状態を示す。図4(A)に示すように、接続端子10の他端には、リード線接続部16が、板部11の上端側(先端側)から上方向に突出される。このリード線接続部16は、接続端子10の板部11と一体で形成されており、断面視が四角形の棒状を成す。なお、このリード線接続部16の形状は、断面視で円形を成していても良い。   FIG. 4A shows a state before the lead wire 15 is connected to the other end of the connection terminal 10, that is, the end opposite to the winding connection portion 14. FIG. 4B shows a state after the lead wire 15 is connected to the connection terminal 10. As shown in FIG. 4A, the lead wire connection portion 16 projects upward from the upper end side (tip end side) of the plate portion 11 at the other end of the connection terminal 10. The lead wire connection portion 16 is formed integrally with the plate portion 11 of the connection terminal 10 and has a quadrangular bar shape in cross-sectional view. In addition, the shape of the lead wire connecting portion 16 may be circular in a sectional view.

リード線15は、一般的な銅の線材が塩化ビニル樹脂で被覆されたものである。ただし、大電流を流すため、太くなっている。リード線15とリード線接続部16とを接続するために、筒状を成すスリーブ20が設けられる。このスリーブ20は、黄銅で形成された円筒形状を成す端子である。   The lead wire 15 is a general copper wire coated with a vinyl chloride resin. However, it is thick in order to pass a large current. In order to connect the lead wire 15 and the lead wire connecting portion 16, a cylindrical sleeve 20 is provided. The sleeve 20 is a cylindrical terminal formed of brass.

スリーブ20は、リード線接続部16に取り付けられる。その後に、リード線15がスリーブ20に挿入される。すると、リード線接続部16とリード線15が平行に配置され、その周囲をスリーブ20が覆った状態となる。つまり、リード線接続部16とリード線15が重なり合う。この状態で、スリーブ20は、前後方向または左右方向から所定の工具により挟持され、かしめられる。つまり、リード線接続部16とリード線15が圧着される。その後、スリーブ20の内部に半田21が流し込まれる(図4(B)参照)。つまり、スリーブ20の内部に半田21が充填される。   The sleeve 20 is attached to the lead wire connecting portion 16. Thereafter, the lead wire 15 is inserted into the sleeve 20. Then, the lead wire connecting portion 16 and the lead wire 15 are arranged in parallel, and the sleeve 20 covers the periphery thereof. That is, the lead wire connecting portion 16 and the lead wire 15 overlap. In this state, the sleeve 20 is clamped by a predetermined tool from the front-rear direction or the left-right direction. That is, the lead wire connecting portion 16 and the lead wire 15 are crimped. Thereafter, the solder 21 is poured into the sleeve 20 (see FIG. 4B). That is, the solder 21 is filled in the sleeve 20.

リード線15とリード線接続部16とを、スリーブ20で覆った状態でかしめるとともに半田21がスリーブ20の内部に流し込まれることで、接続強度を向上させることができ、接続部分の電気抵抗を小さくして、電気を円滑に流すことができるようになる。また、スリーブ20の内部の隙間に半田21が流し込まれることで、異種金属同士の接触で生じる電蝕を生じ難くすることができる。なお、半田18,21には、銅を含まないものを使用することが好ましい。   The lead wire 15 and the lead wire connecting portion 16 are caulked in a state of being covered with the sleeve 20, and the solder 21 is poured into the sleeve 20, so that the connection strength can be improved and the electric resistance of the connecting portion can be improved. It can be made smaller so that electricity can flow smoothly. In addition, since the solder 21 is poured into the gap inside the sleeve 20, it is possible to make it difficult to generate electrolytic corrosion caused by contact between different metals. In addition, it is preferable to use what does not contain copper for the solder 18 and 21. FIG.

黄銅製の接続端子10を用いることで、アルミニウム製の巻線8と銅製のリード線15との接触を排除することができ、アルミニウムと銅との直接接触によって生じる電蝕を防ぐことができる。   By using the connection terminal 10 made of brass, contact between the aluminum winding 8 and the copper lead wire 15 can be eliminated, and galvanic corrosion caused by direct contact between aluminum and copper can be prevented.

また、リード線15とリード線接続部16とがスリーブ20内でかしめられて直接的に強固に接触されることで、リード線との接続部分に、リード線15の許容電流に合わせた大きな電流を流すことができるようになる。この結果、アルミニウムの巻線8を用いたリアクトル1であっても、約25A以上の電流を流すことができるようになる。   Further, since the lead wire 15 and the lead wire connecting portion 16 are caulked in the sleeve 20 and directly contacted firmly, a large current corresponding to the allowable current of the lead wire 15 is connected to the lead wire connecting portion. Will be able to flow. As a result, even with the reactor 1 using the aluminum winding 8, a current of about 25 A or more can flow.

(第2実施形態)
次に、第2実施形態のリアクトル1Aについて図5から図7を用いて説明する。なお、前述した実施形態に示される構成部分と同一構成部分については同一符号を付して重複する説明を省略する。
(Second Embodiment)
Next, the reactor 1A of the second embodiment will be described with reference to FIGS. In addition, about the component same as the component shown by embodiment mentioned above, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

図5および図6に示すように、第2実施形態では、2つの接続端子10A,10Bのうち、一方の接続端子10A(図5中左側)の板部11Aの上下寸法が、他方の接続端子10B(図5中右側)の板部11Bの上下寸法よりも長くなっている。つまり、一方の接続端子10Aの板部11Aの先端が、他方の接続端子10Bの板部11Bの先端よりも突出している。なお、各接続端子10A,10Bの他端側の形状は、第1実施形態と同一のため、説明を省略する。   As shown in FIGS. 5 and 6, in the second embodiment, the vertical dimension of the plate portion 11A of one connection terminal 10A (left side in FIG. 5) of the two connection terminals 10A and 10B is the other connection terminal. It is longer than the vertical dimension of the plate portion 11B of 10B (right side in FIG. 5). That is, the tip of the plate portion 11A of one connection terminal 10A protrudes from the tip of the plate portion 11B of the other connection terminal 10B. In addition, since the shape of the other end side of each connection terminal 10A, 10B is the same as 1st Embodiment, description is abbreviate | omitted.

それぞれの接続端子10A,10Bの板部11A,11Bの先端側には、リード線接続部16A,16Bが形成される。つまり、一方の接続端子10Aのリード線接続部16Aが、他方の接続端子10Bのリード線接続部16Bよりも台座2から離れた位置に設けられる。   Lead wire connection portions 16A and 16B are formed on the tip ends of the plate portions 11A and 11B of the connection terminals 10A and 10B, respectively. That is, the lead wire connection portion 16A of one connection terminal 10A is provided at a position farther from the base 2 than the lead wire connection portion 16B of the other connection terminal 10B.

第2実施形態の接続端子10A,10Bのリード線接続部16A,16Bは、板部11A,11Bから横方向に突出される。一方のリード線接続部16Aと他方のリード線接続部16Bとが、2つの接続端子10A,10Bの並設の方向、つまり、左右方向(水平方向)に向かって突出される。なお、両方のリード線接続部16A,16Bが同一方向(図5中右方向)に突出される。   The lead wire connection portions 16A and 16B of the connection terminals 10A and 10B of the second embodiment protrude from the plate portions 11A and 11B in the lateral direction. One lead wire connection portion 16A and the other lead wire connection portion 16B protrude in the direction in which the two connection terminals 10A and 10B are arranged in parallel, that is, in the left-right direction (horizontal direction). Both lead wire connecting portions 16A and 16B protrude in the same direction (right direction in FIG. 5).

図7(A)は、接続端子10A,10Bにリード線15を接続する前の状態を示す。図7(B)は、接続端子10A,10Bにリード線15を接続した後の状態を示す。図7(A)に示すように、リード線15とリード線接続部16A,16Bとを接続するときに、筒状を成すスリーブ20が設けられる。   FIG. 7A shows a state before the lead wire 15 is connected to the connection terminals 10A and 10B. FIG. 7B shows a state after the lead wire 15 is connected to the connection terminals 10A and 10B. As shown in FIG. 7A, a cylindrical sleeve 20 is provided when connecting the lead wire 15 and the lead wire connecting portions 16A and 16B.

スリーブ20がリード線接続部16A,16Bに取り付けられた状態で、リード線15がスリーブ20に挿入される。また、それぞれのリード線接続部16A,16Bとそれぞれのリード線15が平行に配置され、その周囲をスリーブ20が覆った状態となる。つまり、それぞれのリード線接続部16A,16Bとそれぞれのリード線15が重なり合う。この状態で、スリーブ20は、上下方向または前後方向から所定の工具により挟持され、かしめられる。つまり、それぞれのリード線接続部16A,16Bとそれぞれのリード線15が圧着される。また、スリーブ20の内部に半田21が流し込まれる(図7(B)参照)。つまり、スリーブ20の内部に半田21が充填される。   The lead wire 15 is inserted into the sleeve 20 with the sleeve 20 attached to the lead wire connecting portions 16A and 16B. Further, the lead wire connecting portions 16A and 16B and the lead wires 15 are arranged in parallel, and the sleeve 20 covers the periphery thereof. That is, the lead wire connecting portions 16A and 16B and the lead wires 15 overlap each other. In this state, the sleeve 20 is clamped by a predetermined tool from the vertical direction or the front-rear direction. That is, the respective lead wire connecting portions 16A and 16B and the respective lead wires 15 are crimped. Further, the solder 21 is poured into the sleeve 20 (see FIG. 7B). That is, the solder 21 is filled in the sleeve 20.

第2実施形態では、一方の接続端子10Aのリード線接続部16Aが、他方の接続端子10Bのリード線接続部16Bよりも台座2から離れた位置に設けられることで、一方のリード線接続部16Aに接続されるリード線15と、他方のリード線接続部16Bに接続されるリード線15とが、互いに干渉しないように配置させることができる。このように、2本のリード線15を水平方向に引き出すことができ、配線の引き回しが容易にできるようになる。さらに、空気調和機の室外機などの機器へのリアクトル1Aの組込みにおいて、上部に他の部品や構造物が設けられる場合には、第1実施形態よりもリアクトル1Aの突出寸法を小さくできる利点がある。   In the second embodiment, the lead wire connection portion 16A of one connection terminal 10A is provided at a position farther from the base 2 than the lead wire connection portion 16B of the other connection terminal 10B, whereby one lead wire connection portion. The lead wire 15 connected to 16A and the lead wire 15 connected to the other lead wire connecting portion 16B can be arranged so as not to interfere with each other. Thus, the two lead wires 15 can be drawn out in the horizontal direction, and the wiring can be easily routed. Further, when the reactor 1A is incorporated into a device such as an outdoor unit of an air conditioner, when another component or structure is provided at the top, there is an advantage that the projecting dimension of the reactor 1A can be made smaller than that of the first embodiment. is there.
