Description

この発明は裸体導線とエナメル被覆導線とを接続する端子部材に関する。   The present invention relates to a terminal member for connecting a bare conductor and an enamel-coated conductor.
この分野の技術として、特許文献1記載の技術が知られている。この技術によるとヒュージング処理によってエナメル被覆導線のエナメル被膜を除去し内部の導線と端子部材との間で良好な圧着接続が得られる。このように、従来からエナメル被覆導線と端子部材とを接合する有効な手段の一つとしてヒュージング処理が広く用いられている。   As a technique in this field, a technique described in Patent Document 1 is known. According to this technique, the enamel coating of the enamel-coated conductor is removed by the fusing process, and a good crimp connection is obtained between the inner conductor and the terminal member. As described above, the fusing treatment has been widely used as one of effective means for joining the enamel-coated conductive wire and the terminal member.
また、エナメル被膜やホルマール被膜等の絶縁被膜を有する導線を複数本束ねた導線束に、ヒュージング処理により各導線の絶縁被膜を溶融又は炭化させて端子部材と導線束とを導電接合する技術も一般的に知られた技術である。   Also, there is a technology for electrically bonding the terminal member and the bundle of wires by melting or carbonizing the insulation coating of each conductor by a fusing treatment to a bundle of conductors having a plurality of conductors having an insulation coating such as an enamel coating or a formal coating. This is a generally known technique.
特開2013−175413号公報JP 2013-175413 A
棒状の電磁石の周りに巻かれてモーターのコイル材に用いられるエナメル被覆導線は、その端部で裸体導線に接続され整流子より電流を受ける。このつなぎ目でエナメル被覆導線と裸体導線とを電気的に接続するために例えば一つの筒状の端子部材でヒュージング処理する場合が知られているが、このとき表面状態が相違する2種類の導線を共通の接続手段で接続しようとすると端子部材との間で適切な接続状態が得られない場合がある。   An enamel-coated conductive wire wound around a rod-shaped electromagnet and used as a coil material of a motor is connected to a bare conductive wire at an end thereof and receives a current from a commutator. In order to electrically connect the enamel-coated conductor and the bare conductor at this joint, it is known that a fusing treatment is performed with, for example, one cylindrical terminal member. At this time, two kinds of conductors having different surface states are known. If a common connection means is used for connection, an appropriate connection state may not be obtained with the terminal member.
たとえば、エナメル被覆導線のエナメル被膜が炭化し飛散する条件で通電時間、電流値、かしめ荷重等ヒュージング条件を設定したときには、同時にヒュージング処理される裸体導線に対しては過剰な電流が流れることとなり過熱し溶断する場合がある。また溶断にいたらないまでも裸体導線が高温にさらされことにより線材強度が低下し品質が低下する場合が生じうる。あるいは裸体導線の線材強度が低下しない程度の条件で通電した場合には、エナメル被覆導線の絶縁被膜が炭化除去されないこととなりエナメル被覆導線と端子部材との間で良好な電気的接続が得られない場合がある。   For example, when the fusing conditions such as energization time, current value, and caulking load are set under the condition that the enamel coating of the enamel-coated conductor is carbonized and scattered, excessive current flows to the naked conductor that is subjected to fusing treatment at the same time. May overheat and melt. Moreover, even if it does not lead to fusing, the case where the bare wire is exposed to a high temperature, the wire strength is lowered and the quality may be lowered. Alternatively, when energized under the condition that the wire strength of the bare conductor does not decrease, the insulating coating of the enamel-coated conductor is not removed by carbonization, and a good electrical connection cannot be obtained between the enamel-coated conductor and the terminal member. There is a case.
本発明は、上述した問題に鑑みてなされたものであり、裸体導線の端末とエナメル被覆導線の端末とを電気的機械的に接続する場合であっても裸体導線の強度を低下させることがなく且つエナメル被覆導線の絶縁被膜をヒュージング処理によって適切に炭化し除去できる端子部材を提供することを目的とする。   The present invention has been made in view of the above-described problems, and does not reduce the strength of the naked conductor even when the terminal of the naked conductor and the terminal of the enamel-coated conductor are electrically and mechanically connected. It is another object of the present invention to provide a terminal member that can appropriately carbonize and remove an insulating coating of an enamel-coated conductive wire by a fusing treatment.
本発明の端子部材は、(1)周面を絶縁被膜で被覆された被覆導線をヒュージング処理する熱かしめ接続部を有し前方から後方へ軸状に延びる端子部材であって、前記端子部材の後方に導線をかしめ接続するかしめ接続部が備わるところに特徴を有するものである。   The terminal member of the present invention is (1) a terminal member having a heat caulking connecting portion for fusing a coated conductor whose peripheral surface is coated with an insulating coating, and extending axially from the front to the rear. It is characterized in that a caulking connection part for caulking and connecting a conducting wire is provided behind the cable.
この発明によれば、端子部材はヒュージング処理するための熱かしめ接続部の後方にかしめ接続部が備わるので、前方でエナメル被覆導線など導線の周囲が絶縁被膜で被覆された被覆導線をヒュージング処理して接続することができ、後方で絶縁被膜が被覆されていない裸体導線をかしめ接続することができる。これにより通電による加熱で裸体導線が溶
断したり線材強度が低下したりすることがなく、エナメル被覆導線など絶縁被膜で被覆された被覆導線をヒュージング処理により適切に電気的接続することができる。
According to the present invention, since the terminal member is provided with the caulking connection portion behind the heat caulking connection portion for performing the fusing treatment, the coated conductor in which the periphery of the conducting wire such as the enamel-covered conducting wire is coated with the insulating coating on the front side is fused. It can be processed and connected, and a bare conductor wire not covered with an insulating coating can be caulked and connected behind. As a result, the naked conductor is not melted or the strength of the wire is not lowered by heating due to energization, and the coated conductor covered with the insulating coating such as the enamel-coated conductor can be appropriately electrically connected by the fusing treatment.
熱かしめ接続部は、かしめ接続部と同じ接続構造のもの例えば双方とも筒状体であってよく、また異なる構造のもの例えばかしめ接続部は筒状体で熱かしめ接続部は別の構造のものの場合であってもよい。また、端子部材に対する被覆導線及び導線(以下裸体導線と言う場合がある)の接続する方向は突合せ方向の場合、あるいは同じ方向を向く場合であってよい。   The heat caulking connection part may have the same connection structure as that of the caulking connection part, for example, both may be cylindrical, or different structures, for example, the caulking connection part may be a cylindrical body and the heat caulking connection part may have a different structure. It may be the case. In addition, the direction in which the coated conductor and the conductor (hereinafter sometimes referred to as a naked conductor) are connected to the terminal member may be the butting direction or the same direction.
好ましくは、本発明の端子部材は、(2)前記熱かしめ接続部は断面U字状で重ね合わせ構造であるところに特徴を有する(1)記載のものである。   Preferably, the terminal member according to the present invention is (2) described in (1) characterized in that the heat-caulking connection portion has a U-shaped cross section and has an overlapping structure.
この発明によれば、端子部材の熱かしめ接続部は断面U字状で上下面が重ね合わさる構造なので、たとえば断面矩形のエナメル被覆平角線をヒュージング処理する場合、エナメル被覆平角線の大きさに応じた通電時間、電流値、荷重を設定することで適切な熱かしめ条件によるヒュージング処理ができる。これにより接続界面に原子拡散による合金層が形成され信頼性のある電気的機械的接続が得られる。   According to the present invention, since the heat caulking connection portion of the terminal member has a U-shaped cross section and the upper and lower surfaces are overlapped, for example, when fusing a rectangular enamel-coated rectangular wire, the size of the enamel-coated rectangular wire is set. By setting the energization time, current value, and load according to the fusing process, it is possible to perform the fusing process under appropriate heat caulking conditions. As a result, an alloy layer is formed by atomic diffusion at the connection interface, and a reliable electromechanical connection is obtained.
好ましくは、本発明の端子部材は、(3)前記かしめ接続部は中空の筒状体であるところに特徴を有する(1)又は(2)記載のものである。   Preferably, the terminal member of the present invention is (3) described in (1) or (2) characterized in that the caulking connection portion is a hollow cylindrical body.
この発明によれば、かしめ接続部は中空の筒状体なので、裸体の導線をかしめるのに適している。導線は複数が束になった状態の導線束であってよく束の径に応じた筒状体を選択することで最適のかしめ条件によるかしめ処理ができる。   According to the present invention, since the caulking connection portion is a hollow cylindrical body, it is suitable for caulking a naked conductor. The conductor may be a bundle of conductors in a state where a plurality of conductors are bundled, and the caulking process under the optimum caulking conditions can be performed by selecting a cylindrical body corresponding to the diameter of the bundle.

端子部材1は、金属材料の圧延材から展開形状に型抜きされ必要な塑性加工によって形成される。端子部材1に要求される導電性、加工性、耐食性などを考慮して一般的にりん青銅、黄銅などの銅合金或いは純銅が使用されるがSUS(ステインレス)などの鉄系金属であってよい。耐食性や電気的性能の目標達成のため母材金属表面は金あるいは錫めっきで処理されることがある。   The terminal member 1 is formed from a rolled metal material into a developed shape and formed by necessary plastic working. In consideration of the electrical conductivity, workability, corrosion resistance, etc. required for the terminal member 1, a copper alloy such as phosphor bronze and brass or pure copper is generally used, but it is an iron-based metal such as SUS (stainless). Good. In order to achieve corrosion resistance and electrical performance targets, the base metal surface may be treated with gold or tin plating.
端子部材1は、銅合金の圧延板材から一体的に形成されるもので、図1に示されるよう
に、前方に熱かしめ接続部10、後方にかしめ接続部20を備えている。熱かしめ接続部10とかしめ接続部20は間に備わる連結部60で連なりそれぞれ端子部材1の軸方向の端部に形成されている。熱かしめ接続部10はエナメル被覆平角線40と電気的機械的に接続する部分である。かしめ接続部20は裸体の導線30と電気的機械的に接続する部分である。
The terminal member 1 is integrally formed from a rolled sheet of copper alloy, and as shown in FIG. 1, includes a heat caulking connection portion 10 at the front and a caulking connection portion 20 at the rear. The heat caulking connection portion 10 and the caulking connection portion 20 are connected by a connecting portion 60 provided therebetween, and are respectively formed at end portions of the terminal member 1 in the axial direction. The heat caulking connection portion 10 is a portion that is electrically and mechanically connected to the enamel-coated rectangular wire 40. The caulking connection portion 20 is a portion that is electrically and mechanically connected to the naked conductor 30.
熱かしめ接続部10は、図1に示されるように、断面U字状の左側面が開かれた重ね合わせ構造であって、右側面に湾曲部11を形成し上端部及び下端部から上面部12及び下面部13が連なる。熱かしめ接続部10は前方及び後方に開口部を備え、左側面に上面部12及び下面部13の端部からなる開口部が形成されている。   As shown in FIG. 1, the heat caulking connection portion 10 has a superposed structure in which a left side surface having a U-shaped cross section is opened, a curved portion 11 is formed on the right side surface, and an upper surface portion is formed from the upper end portion and the lower end portion. 12 and the lower surface part 13 continue. The heat caulking connection part 10 has openings on the front and rear sides, and an opening made up of the end portions of the upper surface 12 and the lower surface 13 is formed on the left side.
熱かしめ接続部10は、図2に示されるように、中にエナメル被覆平角線40を保持した状態で湾曲部11を支点にして上面部12及び下面部13により押圧されてヒュージング処理される。ヒュージング処理による熱と荷重で、エナメル被覆平角線40の絶縁被覆が溶融除去され裸体の平角線41の表面が露出し端子部材1の表面と直接接触することとなり、新たにできた接触界面が通電による加熱で融接する。   As shown in FIG. 2, the heat caulking connection portion 10 is pressed by the upper surface portion 12 and the lower surface portion 13 with the curved portion 11 as a fulcrum while the enamel-covered rectangular wire 40 is held therein, and is subjected to a fusing process. . With the heat and load generated by the fusing treatment, the insulating coating of the enamel-covered rectangular wire 40 is melted and removed, and the surface of the bare rectangular wire 41 is exposed and comes into direct contact with the surface of the terminal member 1. It is fusion welded by heating by energization.
エナメル被覆平角線40は、断面矩形の圧延銅板の周面がエナメル被膜で被覆されたものである。使用環境に応じて例えば耐薬品性、耐熱性など化学的機械的特性を備えたエナメル材が準備されこれより適宜選定された最適のエナメル材が圧延銅板の周面に被覆される。   The enamel-coated rectangular wire 40 is obtained by coating the peripheral surface of a rolled copper plate having a rectangular cross section with an enamel coating. For example, an enamel material having chemical mechanical properties such as chemical resistance and heat resistance is prepared according to the use environment, and an optimum enamel material appropriately selected from the enamel material is coated on the peripheral surface of the rolled copper plate.
エナメル被覆平角線40は、ヒュージング処理をおこなうことで事前のエナメル被膜除去工程を経ることなく、エナメル被膜が除去された状態で端子部材1に接続される。ヒュージング処理によりエナメル被膜は熱により炭化され平角線41の母材表面から離脱する。これにより平角線41は裸体の母材銅が表面に現れる。   The enamel-covered rectangular wire 40 is connected to the terminal member 1 in a state where the enamel film is removed without performing a prior enamel film removal step by performing a fusing process. By the fusing treatment, the enamel film is carbonized by heat and detached from the surface of the base material of the flat wire 41. As a result, the bare wire 41 appears on the surface of the flat wire 41.
ヒュージング装置は、図示しないが、かしめ装置にセットされた端子部材の上下方向に備わるかしめ部材である金属構造物が電極の機能をも備えたものであり、通電による加熱条件下でかしめ処理がおこなえるものである。ヒュージング条件は通電時間、電流値、荷重などが主なパラメーターとなりエナメル被膜材種、エナメル被覆平角線、端子部材など各材料によって条件が最適化されるものである。   Although the fusing device is not shown, the metal structure, which is a caulking member provided in the vertical direction of the terminal member set in the caulking device, also has the function of an electrode, and the caulking treatment is performed under heating conditions by energization. It can be done. The fusing conditions are such that the energization time, current value, load, etc. are the main parameters, and the conditions are optimized by each material such as enamel coating material type, enamel-coated rectangular wire, and terminal member.
ヒュージング工程は、図示しないが、エナメル被覆平角線40を熱かしめ接続部10で保持した状態の端子部材1を上下電極の間にセットし、この状態で端子部材1の表面に電極を通して荷重をかけるとともに比較的大きな電流を通電する。これにより、エナメル被膜は炭化し除去される。エナメル被膜が除去されるとほぼ同時に裸体の平角線41及び端子部材1は通電により赤色化するほどまでに加熱されている。そのとき接触界面は原子拡散による合金層が形成されている。このように、ヒュージング処理による熱と荷重で接続部材1と平角線41との接触界面には合金層が形成されるのでかしめ処理に比べて強固な接続状態が形成されるものである。   In the fusing process, although not shown, the terminal member 1 in a state where the enameled rectangular wire 40 is held by the heat caulking connection portion 10 is set between the upper and lower electrodes, and in this state, a load is applied through the electrode to the surface of the terminal member 1. Apply a relatively large current. Thereby, the enamel film is carbonized and removed. At the same time as the enamel coating is removed, the bare rectangular wire 41 and the terminal member 1 are heated so that they turn red when energized. At that time, an alloy layer is formed at the contact interface by atomic diffusion. As described above, an alloy layer is formed at the contact interface between the connecting member 1 and the flat wire 41 by heat and load due to the fusing treatment, so that a stronger connection state is formed compared to the caulking treatment.
熱かしめ接続部10は、図3、図5に示されるように、ヒュージング処理によって、平角線41と上面部12及び下面部13との界面に合金層が形成され信頼性のある接続状態が得られる。接続材料は融着により界面が密接に接合することで空隙の少ない接続構造が得られる。上面部12、下面部13の形状など熱かしめ接続部10の各部のデザインは、ヒュージング処理するエナメル被覆平角線40の条件に応じて適宜設計しうるものである。   As shown in FIG. 3 and FIG. 5, the heat caulking connection portion 10 has a reliable connection state because an alloy layer is formed at the interface between the flat wire 41 and the upper surface portion 12 and the lower surface portion 13 by the fusing process. can get. A connection structure with few voids can be obtained by joining the interface closely by fusion. The design of each part of the heat caulking connection part 10 such as the shapes of the upper surface part 12 and the lower surface part 13 can be appropriately designed according to the conditions of the enamel-coated rectangular wire 40 to be subjected to the fusing process.
熱かしめ接続部10は、図3、図5に示されるように、ヒュージング処理によって上面
部12及び下面部13の平角線41に当接する部分は融着した状態でくぼみ変形しやや肉厚が薄くなっている。上面部12、下面部13、及び平角線41はヒュージング処理による赤色化で軟化し同時に受ける上下方向の荷重により変形が生じ上述のくぼみが形成される。接触界面は融着による原子拡散で新たにCu−Sn合金層が形成されている。
As shown in FIG. 3 and FIG. 5, the heat caulking connection portion 10 is indented and deformed with a slight thickness while the portions that contact the flat wire 41 of the upper surface portion 12 and the lower surface portion 13 are fused. It is getting thinner. The upper surface portion 12, the lower surface portion 13, and the flat wire 41 are softened by reddening by the fusing process and are deformed by the load in the vertical direction received at the same time, so that the above-described depression is formed. A Cu-Sn alloy layer is newly formed at the contact interface by atomic diffusion by fusion.
熱かしめ接続部10は、図3、図5に示されるように、下面部13及び上面部12の左右幅および前後長を適宜設計することでエナメル被覆平角線40の接続範囲を最適値に制御することができる。   As shown in FIGS. 3 and 5, the heat caulking connection portion 10 controls the connection range of the enamel-covered rectangular wire 40 to an optimum value by appropriately designing the left and right widths and the front and rear lengths of the lower surface portion 13 and the upper surface portion 12. can do.
かしめ接続部20は、図1に示されるように、中空の筒状体21であって、かしめる導線束35に適した筒状体21が得られるように板材の型抜き、塑性加工、端縁のロウ付けなどの工程を経て形成される。裸体の導線30の導線束35が中空部に収容され、上下方向からのかしめにより電気的機械的に接続される。   As shown in FIG. 1, the caulking connection portion 20 is a hollow tubular body 21, so that a tubular body 21 suitable for the caulking wire bundle 35 can be obtained by die cutting, plastic working, and edge processing. It is formed through a process such as edge brazing. The conductor bundle 35 of the bare conductor 30 is accommodated in the hollow portion and is electrically and mechanically connected by caulking from the vertical direction.
かしめ接続部20は、図4、図5に示されるように、中に裸体の導線30の導線束35がセットされた状態で固定されている。   As shown in FIGS. 4 and 5, the caulking connection portion 20 is fixed in a state in which the conductor bundle 35 of the bare conductor 30 is set therein.
かしめ接続装置は、図示しないが、裸体の導線束35がセットされている状態の筒状体21に上下方向から荷重を加えて筒状体21の所定の部分を凹状に変形させて導線束35を圧着するものである。圧着により導線束35とかしめ接続部20は電気的機械的に接続される。   Although not shown in the drawing, the caulking connection device applies a load from above and below to the cylindrical body 21 in a state where the naked conductor bundle 35 is set to deform a predetermined portion of the cylindrical body 21 into a concave shape, thereby conducting the conductor bundle 35. Are crimped. The wire bundle 35 and the caulking connection portion 20 are electrically and mechanically connected by crimping.
かしめによる接続条件は、筒状体21のデザイン、導線束サイズ、かしめ条件などがパラメーターになり適宜設定することで最適化されるものである。   The connection condition by caulking is optimized by appropriately setting the design of the cylindrical body 21, the conductor bundle size, the caulking condition, and the like as parameters.
