Description

端子付きケーブル及びその製造方法Cable with terminal and manufacturing method thereof
　本発明は、端部に端子が接続された端子付きケーブル、及び端子付きケーブルの製造方法に関する。 The present invention relates to a cable with a terminal having a terminal connected to an end, and a method for manufacturing the cable with a terminal.
　従来、例えば車両の走行用の駆動力を発生する電気モータに電流を供給するための端子付きケーブルとして、特許文献１に記載のものが知られている。また、このような端子付きケーブルを複数本備えたワイヤハーネスとして、特許文献２に記載のものが知られている。 2. Description of the Related Art Conventionally, for example, a cable described in Patent Document 1 is known as a cable with a terminal for supplying a current to an electric motor that generates a driving force for driving a vehicle. Moreover, the thing of patent document 2 is known as a wire harness provided with two or more such cables with a terminal.
　特許文献１に記載の端子付きケーブルは、複数の素線からなる導体部が超音波溶接によって端子に接続されている。この超音波溶接は、超音波接続装置の超音波ホーンとアンビルとの間に端子の板状基部とケーブルの導体部とを挟み、超音波ホーンからの超音波振動を導体部に付与することで行われる。この端子付きケーブルでは、ケーブルの導体部と端子とが溶接によって接続されるので、大きな電流を流しても、この接続部における電気抵抗を小さくすることができる。 In the cable with a terminal described in Patent Document 1, a conductor portion composed of a plurality of strands is connected to the terminal by ultrasonic welding. This ultrasonic welding is performed by sandwiching the plate-like base portion of the terminal and the conductor portion of the cable between the ultrasonic horn and the anvil of the ultrasonic connecting device, and applying ultrasonic vibration from the ultrasonic horn to the conductor portion. Done. In this cable with a terminal, since the conductor part of the cable and the terminal are connected by welding, even if a large current flows, the electrical resistance at this connection part can be reduced.
　一方、特許文献２に記載のワイヤハーネスのコネクタでは、相手側端子（オス端子）との嵌合方向が、コネクタからのケーブル（電線）の引き出し方向に対して直交している。このため、コネクタに内蔵された端子（メス端子）は、相手側端子との接続部の中心軸線とケーブルに接続される電線接続部の中心軸線とが直交するように折り曲げられ、ケーブルの導体部が電線接続部に加締めによって接続されている。このワイヤハーネスによれば、相手側端子との嵌合方向におけるコネクタの厚みを薄くすることができ、車両への搭載性を向上させることができる。 On the other hand, in the connector of the wire harness described in Patent Document 2, the fitting direction with the mating terminal (male terminal) is orthogonal to the direction of drawing the cable (electric wire) from the connector. For this reason, the terminal (female terminal) built in the connector is bent so that the central axis of the connecting portion with the mating terminal and the central axis of the electric wire connecting portion connected to the cable are orthogonal to each other. Is connected to the wire connection portion by caulking. According to this wire harness, the thickness of the connector in the fitting direction with the counterpart terminal can be reduced, and the mountability to the vehicle can be improved.

　特許文献２に記載のワイヤハーネスでは、相手側端子との接続部の中心軸線と電線接続部の中心軸線とが直交するように端子を折り曲げる必要となるので、端子の製造工程が複雑化してしまう。そこで、本願の発明者らは、端子の製造を容易としながらも相手側端子との嵌合方向に対して直交する方向にケーブルを延在させることが出来るように、端子の一端部において、相手側端子との嵌合方向に対して直交する方向にケーブルの導体部を超音波溶接によって接続することを考えた。 In the wire harness described in Patent Document 2, it is necessary to bend the terminal so that the central axis of the connecting portion with the counterpart terminal and the central axis of the electric wire connecting portion are orthogonal to each other, which complicates the terminal manufacturing process. . Therefore, the inventors of the present application can connect the cable at one end of the terminal so that the cable can be extended in a direction orthogonal to the fitting direction with the mating terminal while facilitating the manufacture of the terminal. The conductor part of the cable was considered to be connected by ultrasonic welding in a direction perpendicular to the fitting direction with the side terminal.
　しかし、ケーブルの導体部が複数の素線からなる場合に、この導体部に超音波ホーンを押し付けると、その押し付け力によって一部の素線が相手部材との接続部から離間する方向に移動してしまい、この一部の素線に超音波ホーンからの超音波振動が付与されなくなる場合があった。このような素線は、逸れ線（はぐれせん）となって溶接された素線の束から遊離し、例えばコネクタ内における絶縁性に影響を与えてしまうおそれがある。 However, when the conductor part of the cable is composed of a plurality of strands, if an ultrasonic horn is pressed against this conductor portion, some of the strands move away from the connecting portion with the mating member due to the pressing force. As a result, ultrasonic vibration from the ultrasonic horn may not be applied to some of the strands. Such a strand may be separated from the bundle of strands that are welded as a broken wire and may affect, for example, insulation in the connector.

More specifically, the terminal 2 has a flat rectangular flat plate portion 20, a cylindrical fitting portion 21 is formed at one end portion in the long side direction, and the other end portion becomes a cable connection portion 22. ing. Assuming that the surface of the flat plate portion 20 on the side shown in FIG. 1 is the upper surface 20 a and the opposite surface is the lower surface 20 b, the upper surface 20 a of the flat plate portion 20 in the fitting portion 21 faces the spring member 3 and the cable connection portion 22. The conductor portion 11 of the cable 10 is welded to the upper surface 20a of the flat plate portion 20 in FIG.
　ケーブル１０は、端子２のケーブル接続部２２において、端子２の相手側端子４との嵌合方向に対して直交する方向に延在している。図１では、この嵌合方向を矢印Ｘで示し、ケーブル接続部２２におけるケーブル１０の延在方向を矢印Ｙで示している。矢印Ｘ方向は平板部２０の長辺方向にあたり、矢印Ｙ方向は平板部２０の短辺方向にあたる。なお、以下の説明では、平板部２０の長辺方向を端子２の長手方向といい、平板部２０の短辺方向を端子２の短手方向ということがある。 The cable 10 extends in a direction orthogonal to the fitting direction of the terminal 2 with the mating terminal 4 at the cable connection portion 22 of the terminal 2. In FIG. 1, this fitting direction is indicated by an arrow X, and the extending direction of the cable 10 at the cable connecting portion 22 is indicated by an arrow Y. The arrow X direction corresponds to the long side direction of the flat plate portion 20, and the arrow Y direction corresponds to the short side direction of the flat plate portion 20. In the following description, the long side direction of the flat plate portion 20 may be referred to as the longitudinal direction of the terminal 2, and the short side direction of the flat plate portion 20 may be referred to as the short direction of the terminal 2.
　ケーブル接続部２２には、端子２の長手方向における嵌合部２１とは反対側の端部に、後述する溶接工程において嵌合部２１から離間する方向への複数の素線１１０の移動を規制する規制突起２２１が設けられている。この規制突起２２１は、端子２となる板状の金属導体を嵌合部２１とは反対側の端部で折り曲げることにより形成されている。本実施の形態では、規制突起２２１が平板部２０の上面２０ａ側に直角に折り曲げられている。平板部２０の上面２０ａに対して垂直な方向の規制突起２２１の高さＨは、超音波溶接された部分の導体部１１の厚みＴよりも高く形成されている。 In the cable connection portion 22, the movement of the plurality of strands 110 in the direction away from the fitting portion 21 in the welding process to be described later is restricted at the end opposite to the fitting portion 21 in the longitudinal direction of the terminal 2. A regulating protrusion 221 is provided. The restricting protrusion 221 is formed by bending a plate-like metal conductor serving as the terminal 2 at the end opposite to the fitting portion 21. In the present embodiment, the regulation protrusion 221 is bent at a right angle toward the upper surface 20 a side of the flat plate portion 20. The height H of the restricting protrusion 221 in the direction perpendicular to the upper surface 20a of the flat plate portion 20 is formed to be higher than the thickness T of the conductor portion 11 in the ultrasonic welded portion.
　ケーブル１０の導体部１１は、溶接部１１ａにおいて端子２のケーブル接続部２２に溶着している。この溶接部１１ａでは、後述する超音波接続装置５の超音波ホーン５３から超音波振動を受けることにより、複数の素線１１０同士が溶け合い、ケーブル接続部２２における平板部２０の上面２０ａに溶着している。 The conductor portion 11 of the cable 10 is welded to the cable connection portion 22 of the terminal 2 at the welded portion 11a. In this welded part 11a, by receiving ultrasonic vibration from an ultrasonic horn 53 of the ultrasonic connecting device 5 described later, the plurality of strands 110 are melted and welded to the upper surface 20a of the flat plate part 20 in the cable connecting part 22. ing.
（超音波接続装置の構成）
　図２は、ケーブル１０の導体部１１を端子２のケーブル接続部２２に超音波溶接するための超音波接続装置５を示す概略図である。 (Configuration of ultrasonic connection device)
FIG. 2 is a schematic diagram showing an ultrasonic connection device 5 for ultrasonic welding of the conductor portion 11 of the cable 10 to the cable connection portion 22 of the terminal 2.
　図２に示すように、本実施の形態に係る超音波接続装置５は、超音波発振器５０と、超音波発振器５０に接続される本体部５１とを備えて構成されている。本体部５１は、端子２が載置されるアンビル５２と、ホーンチップ５３１を先端部に有する超音波ホーン５３と、超音波ホーン５３を支持するホーン支持部５４と、アンビル５２及びホーン支持部５４を固定する基台５５とを備えて構成されている。超音波ホーン５３は、ホーン支持部５４に設けられた図示しない駆動機構によって、上下方向（矢印Ｚ方向）に移動可能である。 As shown in FIG. 2, the ultrasonic connection device 5 according to the present embodiment includes an ultrasonic oscillator 50 and a main body 51 connected to the ultrasonic oscillator 50. The main body 51 includes an anvil 52 on which the terminal 2 is placed, an ultrasonic horn 53 having a horn chip 531 at its tip, a horn support 54 that supports the ultrasonic horn 53, an anvil 52, and a horn support 54. And a base 55 for fixing the frame. The ultrasonic horn 53 can be moved in the vertical direction (arrow Z direction) by a drive mechanism (not shown) provided in the horn support 54.
　超音波ホーン５３の基端部はホーン支持部５４内で支持され、この基端部には、超音波発振器５０に接続された超音波コイルが設けられている。この超音波コイルに超音波発振器５０からの超音波信号が供給されると、超音波ホーン５３が励振される。超音波ホーン５３の超音波振動は、ホーンチップ５３１を介してケーブル１０の導体部１１に伝達され、ホーンチップ５３１に接する部分における導体部１１の素線１１０が加振される。 The base end portion of the ultrasonic horn 53 is supported in the horn support portion 54, and an ultrasonic coil connected to the ultrasonic oscillator 50 is provided at the base end portion. When an ultrasonic signal from the ultrasonic oscillator 50 is supplied to the ultrasonic coil, the ultrasonic horn 53 is excited. The ultrasonic vibration of the ultrasonic horn 53 is transmitted to the conductor portion 11 of the cable 10 via the horn chip 531, and the element wire 110 of the conductor portion 11 in the portion in contact with the horn chip 531 is vibrated.
（端子付きケーブルの製造方法）
　次に、図３Ａ，図３Ｂ，図４Ａ，及び図４Ｂを参照して、端子付きケーブル１の製造方法について説明する。端子付きケーブル１の製造方法は、超音波接続装置５のアンビル５２と超音波ホーン５３のホーンチップ５３１との間に端子２及びケーブル１０の先端部における導体部１１を配置する配置工程と、ホーンチップ５３１をケーブル１０の導体部１１に押し付けた状態で超音波ホーン５３を超音波振動させ、ケーブル１０の導体部１１を端子２のケーブル接続部２２に溶接する溶接工程とを有している。 (Manufacturing method of cable with terminal)
Next, with reference to FIG. 3A, FIG. 3B, FIG. 4A, and FIG. 4B, the manufacturing method of the cable 1 with a terminal is demonstrated. The manufacturing method of the cable 1 with a terminal includes a disposing step of disposing the terminal 2 and the conductor portion 11 at the tip of the cable 10 between the anvil 52 of the ultrasonic connecting device 5 and the horn chip 531 of the ultrasonic horn 53, The ultrasonic horn 53 is ultrasonically vibrated in a state where the chip 531 is pressed against the conductor portion 11 of the cable 10, and the welding step is performed to weld the conductor portion 11 of the cable 10 to the cable connecting portion 22 of the terminal 2.
　図３Ａ及び図３Ｂは、配置工程においてアンビル５２上に配置された端子２、及び端子２のケーブル接続部２２における平板部２０の上面２０ａ側に配置されたケーブル１０の導体部１１を示す説明図である。図３Ａは、端子２及び導体部１１の一部を破断して、端子２の短手方向から見た状態を示している。図３Ｂは、端子２及びケーブル１０を、端子２の長手方向に沿って規制突起２２１側から見た状態を示している。図３Ｂでは、規制突起２２１の奥側（嵌合部２１側）における導体部１１の素線１１０を破線で示している。 3A and 3B are explanatory diagrams showing the terminal 2 arranged on the anvil 52 in the arranging step and the conductor part 11 of the cable 10 arranged on the upper surface 20a side of the flat plate part 20 in the cable connecting part 22 of the terminal 2. FIG. It is. FIG. 3A shows a state in which a part of the terminal 2 and the conductor portion 11 is broken and viewed from the short direction of the terminal 2. FIG. 3B shows a state in which the terminal 2 and the cable 10 are viewed from the regulation protrusion 221 side along the longitudinal direction of the terminal 2. In FIG. 3B, the strand 110 of the conductor part 11 in the back | inner side (fitting part 21 side) of the control protrusion 221 is shown with the broken line.
　配置工程において、ケーブル１０の導体部１１は、端子２のケーブル接続部２２における平板部２０の上面２０ａに接するように配置される。ケーブル１０は、図示しない支持部材によって、被覆部１２から露出した導体部１１が端子２の短手方向に延在するように支持される。 In the arranging step, the conductor part 11 of the cable 10 is arranged so as to be in contact with the upper surface 20a of the flat plate part 20 in the cable connecting part 22 of the terminal 2. The cable 10 is supported by a support member (not shown) so that the conductor portion 11 exposed from the covering portion 12 extends in the short direction of the terminal 2.
　図４Ａ及び図４Ｂは、溶接工程における端子２及びケーブル１０を図３Ａ及び図３Ｂと同方向から見た状態を示す説明図である。 4A and 4B are explanatory views showing a state in which the terminal 2 and the cable 10 in the welding process are viewed from the same direction as FIGS. 3A and 3B.
　溶接工程では、超音波ホーン５３の下方への移動によって、ホーンチップ５３１がケーブル１０の導体部１１を端子２のケーブル接続部２２に押し付ける。そして、この状態で超音波ホーン５３が超音波振動することにより導体部１１の複数の素線１１０が加振され、導体部１１及びケーブル接続部２２の金属表面の酸化被膜や表面層の不純物を飛散させ、接合面に清浄な活性化した金属分子が現れる。更に超音波振動を与えることで、金属原子間の引力を利用して固相溶接状態を作り出し、導体部１１と接続部２２が溶接される。 In the welding process, the horn chip 531 presses the conductor portion 11 of the cable 10 against the cable connection portion 22 of the terminal 2 by moving the ultrasonic horn 53 downward. In this state, the ultrasonic horn 53 vibrates ultrasonically to vibrate a plurality of strands 110 of the conductor portion 11, thereby removing oxide films on the metal surface of the conductor portion 11 and the cable connection portion 22 and impurities on the surface layer. Scattered and clean activated metal molecules appear on the joint surface. Further, by applying ultrasonic vibration, a solid-phase welding state is created using attractive force between metal atoms, and the conductor portion 11 and the connection portion 22 are welded.
　この溶接工程では、超音波ホーン５３の押し付け力による素線１１０の嵌合部２１から離間する方向への移動が、端子２の規制突起２２１によって規制される。すなわち、ケーブル１０の導体部１１をケーブル接続部２２に超音波溶接する際、規制突起２２１によって素線１１０の嵌合部２１から離間する方向の移動を規制した状態で、超音波ホーン５３によって導体部１１を加振する。 In this welding process, the movement of the wire 110 in the direction away from the fitting portion 21 due to the pressing force of the ultrasonic horn 53 is restricted by the restriction protrusion 221 of the terminal 2. That is, when the conductor portion 11 of the cable 10 is ultrasonically welded to the cable connection portion 22, the conductor is connected by the ultrasonic horn 53 while the movement in the direction away from the fitting portion 21 of the element wire 110 is restricted by the restriction protrusion 221. The part 11 is vibrated.
　これにより、複数の素線１１０のうちの一部の素線１１０が逸れ線となって嵌合部２１とは反対側に突き出てしまうことを防ぐことができ、端子付きケーブル１の絶縁性が確保される。なお、嵌合部２１側に突き出る逸れ線が発生したとしても、このような逸れ線は、端子２の周辺におけるコネクタハウジング等の導電性部材に接触しないので、端子付きケーブル１の絶縁性に影響しない。 Thereby, it is possible to prevent a part of the plurality of strands 110 from becoming a broken wire and projecting to the opposite side of the fitting portion 21, and the insulation of the terminal-equipped cable 1 can be prevented. Secured. Even if a stray wire protruding toward the fitting portion 21 is generated, such a stray wire does not come into contact with a conductive member such as a connector housing around the terminal 2, so that the insulation of the cable with terminal 1 is affected. do not do.
（比較例）
　図５は、比較例に係る端子付きケーブル１´を示す斜視図である。この端子付きケーブル１´は、第１の実施の形態に係る端子付きケーブル１と同様に、端子２´にケーブル１０の端部における導体部１１が超音波溶接されているが、この端子２´には、第１の実施の形態に係る端子２の規制突起２２１が設けられていない。図５において、上記第１の実施の形態において説明したものと共通する構成要素については、図１と同一の符号を付して重複した説明を省略する。 (Comparative example)
FIG. 5 is a perspective view showing a terminal-equipped cable 1 ′ according to a comparative example. In this terminal-attached cable 1 ′, the conductor portion 11 at the end of the cable 10 is ultrasonically welded to the terminal 2 ′ similarly to the terminal-attached cable 1 according to the first embodiment. Are not provided with the restricting protrusion 221 of the terminal 2 according to the first embodiment. In FIG. 5, the same components as those described in the first embodiment are denoted by the same reference numerals as those in FIG.
　このような端子２´に対して上記と同様の方法によりケーブル１０の導体部１１を超音波溶接すると、超音波ホーン５３の押し付け力によって複数の素線１１０のうちの一部が素線１１０の束から外れ、嵌合部２１側とは反対側に突出する逸れ線となる場合がある。図５では、逸れ線となった素線１１０を符号１１１で示している。このような逸れ線１１１は、超音波ホーン５３が超音波振動しても加振されないので、端子２´に溶着されず、例えば車両の走行中の振動を受けると、その先端部が大きく振れてしまう。そして、この逸れ線１１１の振れによって絶縁性が損なわれてしまうおそれがある。 When the conductor portion 11 of the cable 10 is ultrasonically welded to such a terminal 2 ′ by the same method as described above, a part of the plurality of strands 110 of the strand 110 is pressed by the pressing force of the ultrasonic horn 53. There is a case where it becomes a broken line protruding from the bundle and projecting to the side opposite to the fitting portion 21 side. In FIG. 5, the strand 110 that has become a broken line is denoted by reference numeral 111. Such a stray line 111 is not vibrated even when the ultrasonic horn 53 is ultrasonically vibrated, so that it is not welded to the terminal 2 ′. End up. And there is a possibility that the insulation is impaired by the deflection of the broken line 111.
（第１の実施の形態の効果）
　以上説明した第１の実施の形態によれば、溶接工程における超音波ホーン５３の押し付け力による素線１１０の嵌合部２１とは反対側への移動が規制突起２２１によって規制されるので、比較例について図５を参照して説明した逸れ線１１１の発生が抑制される。これにより、端子付きケーブル１の絶縁性が確保される。また、規制突起２２１は、端子２となる板状の金属導体を嵌合部２１とは反対側の端部で折り曲げることにより形成されるので、その形成が容易である。 (Effects of the first embodiment)
According to the first embodiment described above, the movement of the element wire 110 to the opposite side of the fitting portion 21 due to the pressing force of the ultrasonic horn 53 in the welding process is restricted by the restriction protrusion 221. The generation of the stray line 111 described with reference to FIG. 5 for the example is suppressed. Thereby, the insulation of the cable 1 with a terminal is ensured. Moreover, since the regulation protrusion 221 is formed by bending a plate-shaped metal conductor serving as the terminal 2 at the end opposite to the fitting portion 21, the formation thereof is easy.
