Abstract
In order to improve contact reliability, this conductive member (A) is provided with: a shape retention conductor (10) which has shape retention properties, a flexible conductor (21) which is flexible; and a joint member (30) in which a first connection unit (31), fixed to the shape retention conductor (10), and a second connection unit (32), having a flat shape and fixed to the flexible conductor (21), are formed. Because the flexible conductor (21) can be placed over the flat second connection unit (32), it is possible to fix the flexible conductor (21) and the second connection unit (32) together with ultrasonic welding. Because oxide film is removed by vibration in the ultrasonic welding step, a higher contact reliability is achieved compared to the case of an attachment method involving only pressing the flexible conductor (21) and the second connection unit (32).
Description
本発明は、導電部材に関するものである。
The present invention relates to a conductive member.
特許文献１には、電気自動車やハイブリッド自動車等の車両においてバッテリー、モータ、インバータ装置等の機器間を配索する手段として、形状保持性を有するパイプと、可撓性を有する被覆電線とを備えた導電部材が開示されている。パイプと被覆電線の芯線を接続する手段として、芯線の端部をパイプの端部内に挿入し、パイプと芯線の端部を扁平状に潰す方法がとられている。
Patent Document 1 includes a pipe having shape retention and a flexible covered electric wire as means for routing between devices such as a battery, a motor, and an inverter device in a vehicle such as an electric vehicle or a hybrid vehicle. A conductive member is disclosed. As a means for connecting the pipe and the core wire of the covered electric wire, a method of inserting the end portion of the core wire into the end portion of the pipe and crushing the end portion of the pipe and the core wire into a flat shape is employed.
上記の接続方法では、パイプや芯線がアルミニウム製である場合に、表面の酸化皮膜を充分に除去することができない。特に、芯線が、複数本のアルミニウム製の素線からなる撚り線で構成されている場合は、酸化皮膜の除去は殆どできない。酸化皮膜が除去されないままでは、パイプと芯線との間の接触抵抗が高くなり、接触信頼性の点で問題が残る。
In the above connection method, when the pipe and the core wire are made of aluminum, the oxide film on the surface cannot be removed sufficiently. In particular, when the core wire is composed of a stranded wire made of a plurality of aluminum strands, the oxide film can hardly be removed. If the oxide film is not removed, the contact resistance between the pipe and the core wire becomes high, and a problem remains in terms of contact reliability.
本発明は上記のような事情に基づいて完成されたものであって、接触信頼性の向上を図ることを目的とする。
The present invention has been completed based on the above circumstances, and an object thereof is to improve contact reliability.
本発明の導電部材は、
形状保持性を有する形状保持導体と、
可撓性を有する柔軟導体と、
前記形状保持導体に固着された第１接続部と、前記柔軟導体に固着された平板状をなす第２接続部とが形成されたジョイント部材とを備えているところに特徴を有する。 The conductive member of the present invention is
A shape-retaining conductor having shape-retaining properties;
A flexible conductor having flexibility;
The present invention is characterized in that it includes a joint member formed with a first connection portion fixed to the shape maintaining conductor and a flat second connection portion fixed to the flexible conductor.
形状保持性を有する形状保持導体と、
可撓性を有する柔軟導体と、
前記形状保持導体に固着された第１接続部と、前記柔軟導体に固着された平板状をなす第２接続部とが形成されたジョイント部材とを備えているところに特徴を有する。 The conductive member of the present invention is
A shape-retaining conductor having shape-retaining properties;
A flexible conductor having flexibility;
The present invention is characterized in that it includes a joint member formed with a first connection portion fixed to the shape maintaining conductor and a flat second connection portion fixed to the flexible conductor.
平板状をなす第２接続部には柔軟導体を重ねることができるので、柔軟導体と第２接続部を超音波溶着等によって固着することが可能である。また、柔軟導体がアルミニウム製の素線からなる撚り線であっても、超音波溶着工程の振動によって素線同士が擦れ合うと同時に撚り線と第２接続部とが擦れ合うので、素線の酸化皮膜が除去される。したがって、単に柔軟導体と第２接続部を加圧するだけの固着方法に比べると、接触信頼性が高い。
Since the flexible conductor can be overlapped on the second connection portion having a flat plate shape, the flexible conductor and the second connection portion can be fixed by ultrasonic welding or the like. In addition, even if the flexible conductor is a stranded wire made of an aluminum strand, the strands rub against each other by the vibration of the ultrasonic welding process, and at the same time, the stranded wire and the second connecting portion rub against each other, so that the strand oxide film Is removed. Therefore, the contact reliability is high as compared with the fixing method in which the flexible conductor and the second connection portion are simply pressurized.

The strand 22 (flexible conductor 21) is made of aluminum or an aluminum alloy. That is, the flexible conductor 21 of the covered conductor 20 is the same material as that of the shape maintaining conductor 10.

The first connecting portion 31 is formed by bending a fan-shaped portion of the plate material before bending so as to form a cylindrical shape. The first connecting portion 31 has a truncated cone shape whose axis is gradually reduced in the forward direction (that is, the direction of assembly to the shape-retaining conductor 10) with the axis line directed in the front-rear direction. Regarding the outer diameter of the first connection portion 31, the front end of the first connection portion 31 has a minimum dimension, and the rear end of the first connection portion 31 has a maximum dimension. The minimum outer diameter dimension of the first connection portion 31 is set to a dimension smaller than the inner diameter of the shape holding conductor 10, and the maximum outer diameter dimension of the first connection portion 31 is set to a dimension larger than the inner diameter of the shape holding conductor 10.

The second connection portion 32 is a means for fixing the joint member 30 to the flexible conductor 21 of the coated conductor 20 so as to be conductive. The 2nd connection part 32 has comprised the flat plate shape which turned a plate | board thickness direction to an up-down direction, and the planar view shape makes a substantially square shape. The central portion in the width direction (left-right direction) at the front end edge of the second connection portion 32 is continuous with the rear end edge portion of the first connection portion 31.

Yes.
次に、本実施例の導電部材Ａの製造工程を説明する。導電部材Ａの製造に際しては、被覆導体２０の前端部において絶縁被覆２３を除去し、柔軟導体２１を露出させる。そして、柔軟導体２１のうち露出部分の素線２２の撚りを解き、素線２２をほぼ真っ直ぐにして束ねた状態にする。次に、絶縁被覆２３の前端部をインシュレーションバレル部３３に載せ、圧着機（図示省略）によりインシュレーションバレル部３３を絶縁被覆２３の外周に巻き付けて締め付ける。この圧着工程により、ジョイント部材３０と被覆導体２０の絶縁被覆２３の前端部とが相対変位を規制された状態に固着される。
Next, the manufacturing process of the conductive member A of the present embodiment will be described. In manufacturing the conductive member A, the insulating coating 23 is removed at the front end portion of the coated conductor 20 to expose the flexible conductor 21. Then, the strands 22 of the exposed portion of the flexible conductor 21 are untwisted so that the strands 22 are almost straight and bundled. Next, the front end portion of the insulating coating 23 is placed on the insulation barrel portion 33, and the insulation barrel portion 33 is wound around the outer periphery of the insulating coating 23 by a crimping machine (not shown) and tightened. By this crimping step, the joint member 30 and the front end portion of the insulating coating 23 of the coated conductor 20 are fixed in a state where relative displacement is restricted.
インシュレーションバレル部３３と絶縁被覆２３を圧着した後、ジョイント部材３０と被覆導体２０を超音波溶接装置（図示省略）のアンビルに移載する。このとき、柔軟導体２１の露出した前端部が第２接続部３２の上面に載置されている。アンビルに載置した後、柔軟導体２１に対し上方からホーンを押し当て、第２接続部３２と柔軟導体２１を上下方向（第２接続部３２の板厚方向と平行な方向）に加圧しながら、ホーンを超音波振動させる。
After the insulation barrel portion 33 and the insulating coating 23 are pressure-bonded, the joint member 30 and the coated conductor 20 are transferred to the anvil of the ultrasonic welding apparatus (not shown). At this time, the exposed front end portion of the flexible conductor 21 is placed on the upper surface of the second connection portion 32. After placing on the anvil, a horn is pressed against the flexible conductor 21 from above, and the second connecting portion 32 and the flexible conductor 21 are pressed in the vertical direction (a direction parallel to the plate thickness direction of the second connecting portion 32). , Ultrasonically vibrate the horn.
ホーンの超音波振動が素線２２と第２接続部３２に伝達されると、接触している素線２２同士が超音波溶着されるとともに、第２接続部３２と、第２接続部３２に接触している素線２２とが超音波溶着される。このとき、素線２２同士が超音波振動によって摺接するとともに、素線２２と第２接続部３２とが超音波振動によって摺接するので、素線２２の表面の酸化皮膜が擦り落とされる。これにより、素線２２同士が導通可能に接触した状態で固着されるとともに、素線２２と第２接続部３２とが導通可能に接触した状態で固着される。以上により、被覆導体２０とジョイント部材３０が一体化される。
When the ultrasonic vibration of the horn is transmitted to the strand 22 and the second connection portion 32, the contacting strands 22 are ultrasonically welded to each other, and to the second connection portion 32 and the second connection portion 32. The contacting wire 22 is ultrasonically welded. At this time, the strands 22 are brought into sliding contact with each other by ultrasonic vibration, and the strand 22 and the second connecting portion 32 are brought into sliding contact with each other by ultrasonic vibration, so that the oxide film on the surface of the strand 22 is scraped off. Accordingly, the strands 22 are fixed in a state where they are in contact with each other so as to be conductive, and the strand 22 and the second connecting portion 32 are fixed in a state where they are in contact with each other so as to be conductive. As described above, the covered conductor 20 and the joint member 30 are integrated.
この後、ジョイント部材３０の第１接続部３１を形状保持導体１０の後端部に挿入する。このとき、第１接続部３１の前端部の外径は形状保持導体１０の内径より小さいので、第１接続部３１を形状保持導体１０内にスムーズに挿入することができる。第１接続部３１の外周面は、後端側に向かって次第に外径が大きくなるような形状をなしているので、挿入の途中で、第１接続部３１の外周面が形状保持導体１０の後端部の内周縁部に摺接する。この摺接により、形状保持導体１０の内周縁部の酸化皮膜が擦り取られる。
Thereafter, the first connecting portion 31 of the joint member 30 is inserted into the rear end portion of the shape maintaining conductor 10. At this time, since the outer diameter of the front end portion of the first connection portion 31 is smaller than the inner diameter of the shape retaining conductor 10, the first connection portion 31 can be smoothly inserted into the shape retaining conductor 10. Since the outer peripheral surface of the first connection portion 31 is shaped so that the outer diameter gradually increases toward the rear end side, the outer peripheral surface of the first connection portion 31 is in the middle of the insertion of the shape maintaining conductor 10. It is in sliding contact with the inner peripheral edge of the rear end. By this sliding contact, the oxide film on the inner peripheral edge of the shape maintaining conductor 10 is scraped off.
第１接続部３１の外周が全周に亘って形状保持導体１０の後端部内周縁に当接したら、この当接部分をレーザー溶接等によって固着する。これにより、ジョイント部材３０と形状保持導体１０が接続され、形状保持導体１０と被覆導体２０がジョイント部材３０を介して導通可能に接続される。
When the outer periphery of the first connection portion 31 is in contact with the inner peripheral edge of the rear end portion of the shape maintaining conductor 10 over the entire periphery, the contact portion is fixed by laser welding or the like. Thereby, the joint member 30 and the shape maintaining conductor 10 are connected, and the shape maintaining conductor 10 and the covered conductor 20 are connected through the joint member 30 so as to be conductive.
本実施例の導電部材Ａは、形状保持性を有する形状保持導体１０と、可撓性を有する柔軟導体２１と、ジョイント部材３０とを備えている。柔軟導体２１は、柔軟導体２１を包囲する絶縁被覆２３と一体化されることで被覆導体２０を構成する。ジョイント部材３０には、形状保持導体１０に固着された第１接続部３１と、柔軟導体２１に固着された平板状をなす第２接続部３２とが形成されている。平板状をなす第２接続部３２には柔軟導体２１を重ねることができるので、柔軟導体２１と第２接続部３２を超音波溶着等によって固着することが可能である。これにより、本実施例では、超音波溶着を実現している。
The conductive member A of the present embodiment includes a shape-retaining conductor 10 having shape-retaining properties, a flexible conductor 21 having flexibility, and a joint member 30. The flexible conductor 21 constitutes the coated conductor 20 by being integrated with an insulating coating 23 surrounding the flexible conductor 21. The joint member 30 is formed with a first connection portion 31 fixed to the shape maintaining conductor 10 and a flat second connection portion 32 fixed to the flexible conductor 21. Since the flexible conductor 21 can be stacked on the second connection portion 32 having a flat plate shape, the flexible conductor 21 and the second connection portion 32 can be fixed by ultrasonic welding or the like. Thereby, in this embodiment, ultrasonic welding is realized.
また、柔軟導体２１はアルミニウム製又はアルミニウム合金製の素線２２からなる撚り線であるが、超音波溶着工程の振動によって素線２２同士が擦れ合うと同時に撚り線と第２接続部３２とが擦れ合うので、素線２２の酸化皮膜が除去される。したがって、単に柔軟導体２１と第２接続部３２を加圧するだけの固着方法に比べると、接触信頼性が高い。
Further, the flexible conductor 21 is a stranded wire made of an aluminum or aluminum alloy strand 22, but the strands 22 rub against each other due to vibration in the ultrasonic welding process, and at the same time, the stranded wire and the second connecting portion 32 rub against each other. Therefore, the oxide film of the strand 22 is removed. Therefore, the contact reliability is high as compared with the fixing method in which the flexible conductor 21 and the second connection portion 32 are simply pressurized.
また、ジョイント部材３０には、絶縁被覆２３の外周に固着されたインシュレーションバレル部３３が形成されている。この構成によれば、ジョイント部材３０と被覆導体２０とを確実に接続することができる。
Also, the joint member 30 is formed with an insulation barrel portion 33 fixed to the outer periphery of the insulating coating 23. According to this configuration, the joint member 30 and the covered conductor 20 can be reliably connected.
また、形状保持導体１０はパイプ状をなしており、第１接続部３１は、形状保持導体１０の内部に挿入されているので、形状保持導体１０と第１接続部３１との接続部分の外径寸法を、形状保持導体１０の外径と同じ寸法に収めることができる。また、第１接続部３１は、形状保持導体１０への挿入方向前方に向かって縮径した円錐台状をなしているので、内径の異なる複数種類の形状保持導体１０に対し、１種類のジョイント部材３０を適用することができる。
In addition, since the shape retaining conductor 10 has a pipe shape and the first connection portion 31 is inserted into the shape retaining conductor 10, the shape retaining conductor 10 is outside the connection portion between the shape retaining conductor 10 and the first connection portion 31. The diameter dimension can be accommodated in the same dimension as the outer diameter of the shape retaining conductor 10. Moreover, since the 1st connection part 31 has comprised the truncated cone shape diameter-reduced toward the insertion direction to the shape maintenance conductor 10, it is one kind of joint with respect to the multiple types of shape maintenance conductor 10 from which an internal diameter differs.
