Description

本発明は、電線及びその製造方法に関する。   The present invention relates to an electric wire and a manufacturing method thereof.

自動車などの車両において配策されるワイヤーハーネスは、電線と、当該電線の端部に接続される部品（例えば端子）と、を備える。電線は、銅などの導電性金属からなる多数の撚り線と、当該撚り線を被覆する絶縁被覆と、を有している。
従来から、電線と端子とを電気的、機械的に接続する方法として、電線の端部の絶縁被覆を剥離して撚り線を露出させ、当該露出した撚り線に端子の一部（例えば一対のバレル片）をかしめつけたり圧着する等の方法が採られている。 A wire harness arranged in a vehicle such as an automobile includes an electric wire and a component (for example, a terminal) connected to an end of the electric wire. The electric wire has a large number of stranded wires made of a conductive metal such as copper, and an insulating coating that covers the stranded wires.
Conventionally, as a method of electrically and mechanically connecting an electric wire and a terminal, the insulation coating at the end of the electric wire is peeled to expose the stranded wire, and a part of the terminal (for example, a pair of terminals) is exposed to the exposed stranded wire. A method such as caulking or crimping a barrel piece) is employed.

しかしながら、上記の方法により、電線と端子とを接続すると、端子の一部が電線の端部を覆うように配されるため、大電流用の電線のように太い電線を端子に接続する場合には、電線と端子との接続部が大型化するという問題があった。   However, when connecting the electric wire and the terminal by the above method, since a part of the terminal is arranged so as to cover the end of the electric wire, when connecting a thick electric wire to the terminal like the electric wire for large current Has a problem that the connecting portion between the electric wire and the terminal is enlarged.

そこで、電線と端子との接続部を小型化する方法を検討した。電線と端子との接続部を小型化する方法としては、例えば、電線の露出した撚り線を端子の上に載置して超音波溶着や抵抗溶接法により両者を接続することが考えられる（例えば特許文献１および特許文献２を参照）。   Then, the method of miniaturizing the connection part of an electric wire and a terminal was examined. As a method for reducing the size of the connection portion between the electric wire and the terminal, for example, it is conceivable to place the exposed stranded wire of the electric wire on the terminal and connect them by ultrasonic welding or resistance welding (for example, (See Patent Document 1 and Patent Document 2).

特開２００２−２３９７５２号公報JP 2002-239752 A 特開２００８−１３７０３３号公報JP 2008-137033 A

電線と端子とを、超音波溶着により接続すると、溶着時の摩擦熱や振動などにより、撚り線の表面が損傷を受けて、断線が生じるおそれがある。一方、抵抗溶接法により電線と端子とを接続すると、撚り線だけが加熱されて固まるため、予め撚り線を加熱して固めておいてから抵抗溶接する必要があり、手間がかかる。
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、撚り線に損傷を与えず、かつ、低コストな方法により省スペースな電線を提供することを目的とする。 If the electric wire and the terminal are connected by ultrasonic welding, the surface of the stranded wire may be damaged due to frictional heat or vibration during welding, and disconnection may occur. On the other hand, when the electric wire and the terminal are connected by the resistance welding method, only the stranded wire is heated and hardened. Therefore, it is necessary to heat and harden the stranded wire in advance, and resistance welding is required.
The present invention has been completed based on the above situation, and an object thereof is to provide a space-saving electric wire by a low-cost method without damaging a stranded wire.

上記課題を解決するものとして、本発明は、複数本の撚り線、前記撚り線を覆う絶縁被覆、および他の部品との接続部を備える電線であって、前記接続部を、前記絶縁被覆の除去により露出した露出撚り線に、ろう材を含浸させることにより設けたところに特徴を有する。   In order to solve the above-mentioned problems, the present invention provides a plurality of stranded wires, an insulating coating that covers the stranded wires, and an electric wire including a connecting portion with another component, and the connecting portion is made of the insulating coating. It is characterized in that it is provided by impregnating a brazing material into an exposed stranded wire exposed by removal.

また上記課題を解決するものとして、本発明は、複数本の撚り線、前記撚り線を覆う絶縁被覆、および他の部品との接続部を備える電線の製造方法であって、前記絶縁被覆を除去することにより撚り線を露出させ、当該露出した露出撚り線にろう材を含浸させるところに特徴を有する。   In order to solve the above-mentioned problem, the present invention provides a method of manufacturing an electric wire comprising a plurality of stranded wires, an insulating coating covering the stranded wire, and a connecting portion with another component, and the insulating coating is removed. Thus, the stranded wire is exposed, and the exposed exposed stranded wire is impregnated with a brazing material.

本発明においては、電線の露出撚り線にろう材を含浸させることにより他の部品（電線に接続される端子などの部品）との接続部が設けられる。これにより以下のような効果を得ることができる。
（１）電線の接続部を、他の部品に直接接続することができるので、他の部品に接続するための端子が不要となる。その結果、低コストとすることができ、かつ、電線の配されるスペースを省スペース化することができる。
（２）電線を端子にかしめつけたり圧着する方法や、上記特許文献１〜２に提案されている方法では、電線を搭載している車両等の振動等により電線と端子との接続部の断線の発生が懸念されるが、電線を他の部品に直接接続することにより、電気的な接続信頼性を高めることができる。
（３）露出撚り線にろう材を含浸させることにより接続部が設けられるので、撚り線の表面が損傷を受けることがないうえに、一工程で電線に接続部を設けることができ、強度にも優れる。 In this invention, a connection part with other components (components, such as a terminal connected to an electric wire) is provided by impregnating the brazing material into the exposed strand of an electric wire. As a result, the following effects can be obtained.
(1) Since the connection part of an electric wire can be directly connected to another component, the terminal for connecting to another component becomes unnecessary. As a result, the cost can be reduced and the space where the electric wires are arranged can be saved.
(2) In the method of caulking and crimping the electric wire to the terminal, or the method proposed in Patent Documents 1 and 2 above, the disconnection of the connection portion between the electric wire and the terminal due to vibration of a vehicle or the like on which the electric wire is mounted Although there is concern about the occurrence, electrical connection reliability can be improved by directly connecting the electric wire to other components.
(3) Since the connection portion is provided by impregnating the exposed stranded wire with the brazing material, the surface of the stranded wire is not damaged, and the connection portion can be provided in the electric wire in one step, and the strength is increased. Also excellent.

本発明は、以下の構成であるのが好ましい。
複数本の撚り線を互いに接触した状態で並列させてなるフラット導体を、絶縁被覆でフラット形状に覆った構成、すなわち、電線がフラット形状であると、厚みを小さくすることができるので、さらなる省スペース化が可能となり好ましい。 The present invention preferably has the following configuration.
A structure in which flat conductors formed by paralleling a plurality of stranded wires in contact with each other is covered with a flat shape with an insulating coating, i.e., if the electric wire has a flat shape, the thickness can be reduced. This is preferable because it enables space.

接続部に、孔開け加工が施されている構成とすると、孔開け加工により設けられた接続部の孔に、端子などの部品を挿通させるなどの簡易な方法により接続することができる。   If the connection portion is configured to be perforated, the connection portion can be connected by a simple method such as inserting a part such as a terminal into the hole of the connection portion provided by the perforation processing.

露出撚り線をシート状のろう材で覆い、シート状のろう材で覆われた露出撚り線を誘導加熱することにより、ろう材を含浸させる構成とすると、ペースト状のろう材などを用いるよりも、ろう材を含浸させる作業を簡素化できるので好ましい。
ろう材が、りん銅ろうであると、耐熱性、強度、親和性に優れるので好ましい。 Covering the exposed stranded wire with a sheet-like brazing material and inducing the brazing material by induction heating of the exposed stranded wire covered with the sheet-like brazing material, rather than using a paste-like brazing material, etc. It is preferable because the work of impregnating the brazing material can be simplified.
It is preferable that the brazing material is phosphor copper brazing because it is excellent in heat resistance, strength and affinity.

＜実施形態１＞
本発明の実施形態１を図１ないし図７によって説明する。
本実施形態の電線１０は、例えば電気自動車において走行用の動力源を構成するバッテリ、インバータ、モータなどの装置（図示せず）の間に配索されるものであり、例えば、図１に示すようにバッテリを構成する電池セル３０の上部に設けた端子３１（他の部品３１に相当）に接続される。 <Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS.
The electric wire 10 of this embodiment is routed between devices (not shown) such as a battery, an inverter, and a motor that constitute a power source for traveling in an electric vehicle, for example, as shown in FIG. Thus, it connects to the terminal 31 (equivalent to the other components 31) provided in the upper part of the battery cell 30 which comprises a battery.

電線１０は、図２に示すように、扁平な形状のフラット導体１１が、フラット形状（ほぼ一定の厚みで平坦な形状）の樹脂製の絶縁被覆１３に覆われて構成されたフラットケーブル１０である。電線１０の端末部１０Ａでは、絶縁被覆１３が剥ぎ取られることによりフラット導体１１が露出している。   As shown in FIG. 2, the electric wire 10 is a flat cable 10 in which a flat conductor 11 having a flat shape is covered with a resin insulating coating 13 having a flat shape (a flat shape with a substantially constant thickness). is there. In the terminal portion 10A of the electric wire 10, the flat conductor 11 is exposed by peeling off the insulating coating 13.

フラット導体１１は、複数本の撚り線１２を互いに接触した状態で並列させることにより全体としてほぼ一定の厚みのフラットな形状とされており、各撚り線１２としては、多数の銅合金の金属素線を螺旋状に撚り合わせてなるものが用いられている。   The flat conductor 11 is formed into a flat shape having a substantially constant thickness as a whole by arranging a plurality of stranded wires 12 in parallel with each other in contact with each other, and each stranded wire 12 has a large number of copper alloy metal elements. A wire formed by twisting wires in a spiral shape is used.

フラット導体１１が露出している電線１０の端末部１０Ａには、露出した撚り線１２（「露出撚り線１２」に相当）にろう材２５を含浸させてなる接続部１５（図２において網掛けで示されている部分）が設けられている。接続部１５は電線１０と電池セル３０の端子３１とを、機械的および電気的に接続する部分である。
接続部１５には、孔開け加工を施すことにより形成された円形の接続孔１６が設けられている。この接続孔１６にボルト状の端子３１を挿通させナット３２を螺合させることにより、電線１０と電池セル３０の端子３１とが接続される。 In the terminal portion 10A of the electric wire 10 where the flat conductor 11 is exposed, a connecting portion 15 (shaded in FIG. 2) is formed by impregnating the exposed stranded wire 12 (corresponding to “exposed stranded wire 12”) with a brazing material 25. The portion indicated by) is provided. The connection portion 15 is a portion that mechanically and electrically connects the electric wire 10 and the terminal 31 of the battery cell 30.
The connection portion 15 is provided with a circular connection hole 16 formed by drilling. The electric wire 10 and the terminal 31 of the battery cell 30 are connected by inserting the bolt-shaped terminal 31 into the connection hole 16 and screwing the nut 32.

電線１０の露出撚り線１２に含浸されるろう材２５としては、耐熱性、耐食性を有する銅ろう、銀ろう、アルミニウムろう、りん銅ろう、ニッケルろう、金ろう、パラジウムろう、マグネシウムろうなどを使用することができる。これらのろう材２５のうち、耐熱性、強度、親和性に優れるという点で、りん銅ろうが好ましく、りん銅ろうのなかでも特に銀入りのもの（「銀入りりん銅ろう」という）が好ましい。   As the brazing material 25 impregnated in the exposed stranded wire 12 of the electric wire 10, copper brazing, silver brazing, aluminum brazing, phosphor copper brazing, nickel brazing, gold brazing, palladium brazing, magnesium brazing, etc. having heat resistance and corrosion resistance are used. can do. Among these brazing materials 25, phosphor copper brazing is preferable in terms of excellent heat resistance, strength, and affinity, and among the phosphor copper brazing, silver-containing one (referred to as "silver containing phosphor copper brazing") is particularly preferable. .

本実施形態の電線１０は、例えば以下に説明する方法により製造することができる。
フラット形状の電線１０の端末部１０Ａの絶縁被覆１３を剥ぎ取って、撚り線１２を露出させる（図３を参照）。次に、露出撚り線１２に、シート状のろう材２５（例えば、銀入りりん銅ろう、ＪＩＳ Ｚ３２６４、Ｂ−ＣｕＰ５）を巻いて、露出撚り線１２の端部１２Ａを含む領域を覆う（図４を参照）。 The electric wire 10 of this embodiment can be manufactured by the method demonstrated below, for example.
The insulation coating 13 of the terminal portion 10A of the flat electric wire 10 is peeled off to expose the stranded wire 12 (see FIG. 3). Next, a sheet-like brazing material 25 (for example, silver-containing phosphor copper brazing, JIS Z3264, B-CuP5) is wound around the exposed stranded wire 12 to cover the region including the end 12A of the exposed stranded wire 12 (see FIG. 4).

ろう材２５により覆われた撚り線１２を図示上下方向から、治具４０で固定する（図５を参照）。
ここで、治具４０の端部を、絶縁被覆１３の端部と一致するように配すると、誘電加熱により絶縁被覆１３が高温となって溶融することが懸念されるため、図５および図６に示すように、治具４０を、その端部と絶縁被覆１３の端部との間から露出撚り線１２の一部が目視できるような位置に配する。 The stranded wire 12 covered with the brazing material 25 is fixed with a jig 40 from the vertical direction in the figure (see FIG. 5).
Here, if the end portion of the jig 40 is arranged so as to coincide with the end portion of the insulating coating 13, there is a concern that the insulating coating 13 is melted at a high temperature due to dielectric heating. As shown in FIG. 2, the jig 40 is arranged at a position where a part of the exposed stranded wire 12 can be visually observed between the end portion and the end portion of the insulating coating 13.

本実施形態で用いる治具４０は、図５に示すように、電線１０の上側に配されるコ字状の治具４０Ａと、電線１０の下側に配される平板状の治具４０Ｂとから構成される。治具４０を構成する材料としては、ろう材２５との親和性の低い材料であればよく、例えば、セラミック、アルミナ、石英等が挙げられる。   As shown in FIG. 5, the jig 40 used in the present embodiment includes a U-shaped jig 40 </ b> A disposed on the upper side of the electric wire 10, and a flat jig 40 </ b> B disposed on the lower side of the electric wire 10. Consists of The material constituting the jig 40 may be any material having low affinity with the brazing material 25, and examples thereof include ceramic, alumina, quartz, and the like.

次に、図５に示すように、電源４６のスイッチを入れてコイル４５に電流を流して、公知の手法により誘導加熱を行う。誘導加熱の条件は、ろう材２５の種類や電線１０の材質などにもよるが、例えば、８５０℃で５秒間の加熱を行う。   Next, as shown in FIG. 5, the power supply 46 is turned on, a current is passed through the coil 45, and induction heating is performed by a known method. The induction heating conditions depend on the type of the brazing material 25 and the material of the electric wire 10, but for example, heating is performed at 850 ° C. for 5 seconds.

誘導加熱を行うことにより加熱されたろう材２５が溶融拡散して、撚り線１２を構成する金属素線間の内部と表面に充填され、これにより接続部１５が形成される（図７を参照）。次に、接続部１５の所定の位置に孔開け加工を施して接続孔１６を設けると、図２に示す本実施形態の電線１０が得られる。   The brazing filler metal 25 heated by induction heating is melted and diffused to fill the inside and the surface between the metal wires constituting the stranded wire 12, thereby forming the connection portion 15 (see FIG. 7). . Next, when the connection hole 16 is provided by drilling at a predetermined position of the connection portion 15, the electric wire 10 of the present embodiment shown in FIG. 2 is obtained.

次に、本実施形態の効果について説明する。
本実施形態によれば、電線１０の露出撚り線１２にろう材２５を含浸させることにより、電池セル３０の端子３１との接続部１５が設けられる。これにより以下のような効果を得ることができる。
電線１０を、電池セル３０の端子３１に直接接続することができるので、電池セル３０の端子３１に接続するための端子が不要となる。その結果、低コストとすることができ、かつ、電線１０の配されるスペースを省スペース化することができる。また、電線１０が電池セル３０の端子３１に直接接続されるので、電気的な接続信頼性を高めることができる。
さらに、露出撚り線１２にろう材２５を含浸させることにより接続部１５が設けられるので、撚り線１２の表面が損傷を受けることがないうえに、一工程で電線１０に接続部１５を設けることができ、強度にも優れる。
従って、本実施形態によれば、撚り線１２に損傷を与えず、かつ低コストな方法により省スペースな電線１０を提供することができるのである。 Next, the effect of this embodiment will be described.
According to this embodiment, the connection part 15 with the terminal 31 of the battery cell 30 is provided by impregnating the brazing material 25 into the exposed stranded wire 12 of the electric wire 10. As a result, the following effects can be obtained.
Since the electric wire 10 can be directly connected to the terminal 31 of the battery cell 30, the terminal for connecting to the terminal 31 of the battery cell 30 becomes unnecessary. As a result, the cost can be reduced and the space where the electric wires 10 are arranged can be saved. Moreover, since the electric wire 10 is directly connected to the terminal 31 of the battery cell 30, electrical connection reliability can be improved.

Therefore, according to this embodiment, the space-saving electric wire 10 can be provided by a low-cost method without damaging the stranded wire 12.

また、本実施形態では、複数本の撚り線１２を互いに接触した状態で並列させてなるフラット導体１１を、絶縁被覆１３でフラット形状に覆った構成、すなわち、電線１０がフラット形状をなしているので、電線１０の厚みを小さくすることができ、さらなる省スペース化が可能となる。   Moreover, in this embodiment, the structure which covered the flat conductor 11 formed by paralleling the several strand wire 12 in the state which mutually contacted in the flat shape with the insulation coating 13, ie, the electric wire 10, has comprised the flat shape. Therefore, the thickness of the electric wire 10 can be reduced, and further space saving can be achieved.

また、本実施形態によれば、電線１０の接続部１５に、孔開け加工が施されることにより接続孔１６が設けられているので、当該接続孔１６に、電池セル３０の端子３１を挿通させナット３２止めするだけで電線１０と電池セル３０の端子３１とを接続することができる。その結果、電線１０と他の部品３１とを簡易な方法により接続することができる。   Further, according to the present embodiment, since the connection hole 16 is provided by drilling the connection portion 15 of the electric wire 10, the terminal 31 of the battery cell 30 is inserted into the connection hole 16. The electric wire 10 and the terminal 31 of the battery cell 30 can be connected simply by fixing the nut 32. As a result, the electric wire 10 and the other component 31 can be connected by a simple method.

さらに、本実施形態によれば、露出撚り線１２をシート状のろう材２５で覆い、シート状のろう材２５で覆われた露出撚り線１２を誘導加熱することにより、ろう材２５を含浸させるから、ろう材２５を含浸させる作業を簡素化できる。   Furthermore, according to the present embodiment, the exposed stranded wire 12 is covered with the sheet-like brazing material 25, and the exposed stranded wire 12 covered with the sheet-like brazing material 25 is induction-heated to impregnate the brazing material 25. Therefore, the work of impregnating the brazing material 25 can be simplified.
