【発明の属する技術分野】
本発明は、シールド電線とその編組処理方法に関する。
【0002】
【従来の技術】
従来のシールド電線、例えば、図7に示すシールド電線1は、撚り線からなる導体2の外周に絶縁体3、金属製の細線を織った編組4及びシース5がこの順に配置されている。
シールド電線1は、例えば、電気自動車の配線に使用する場合には、電磁環境適合性(EMC: electro-magnetic compatibility)の観点から電磁波シールドの対策を採る必要から、端部のシース5を一部除去して露出させた編組4をシールド処理している。このような場合、従来のシールド電線1は、予め取り付けておいた電気伝導性の金属からなるキャップ7を編組4とシース5との境目近傍に配置し、図8及び図9に示すように、編組4を折り返してキャップ7に被せることで、編組4とキャップ7とを電気的に接続している。
【0003】
【発明が解決しようとする課題】
ところで、編組4は、スズメッキ軟銅線等からなる金属製の細線を織ったものであるから、折り返す作業に手間が掛かって面倒なうえ、折り返す際にばらけてしまうという問題があった。この場合、編組4がばらけると、シールド電線1は、編組4とキャップ7とが均一に接触せず編組処理の品質が不均一になる。また、シールド電線1は、編組4を折り返して編組処理するため、処理作業を機械を用いて自動化することが難しい。
【0004】
本発明は上記の点に鑑みてなされたもので、編組処理の作業性に優れ、処理品質が均一化でき、編組処理を自動化することが可能なシールド電線とその編組処理方法を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記目的を達成するため本発明のシールド電線においては、導体の外周に絶縁体、編組及びシースが配置されるシールド電線において、前記絶縁体と編組との間に前記編組を拡開させる拡開部材が複数配置されている構成としたのである。
また、上記目的を達成するため本発明のシールド電線の編組処理方法においては、導体の外周に絶縁体、編組及びシースが配置されると共に、前記絶縁体と編組との間に前記編組を拡開させる拡開部材が複数配置されているシールド電線の、前記複数の拡開部材によって当該シールド電線端部の前記編組を拡開させ、当該シールド電線端部側から導電性部材を取り付けて前記編組と導電性部材とを電気的に接続する構成としたのである。
【0006】
好ましくは、前記拡開部材をワイヤとし、前記ワイヤが前記絶縁体に螺旋状に巻回されているものとする。
【0007】
【発明の実施の形態】
以下、本発明のシールド電線とその編組処理方法に係る一実施形態を図1乃至図6に基づいて詳細に説明する。
シールド電線10は、図1及び図2に示すように、導体11の外周に絶縁体12、4本のワイヤ13、編組14及びシース15がこの順に配置されている。
【0008】
導体11は、複数の素線を撚り合わせた撚り線である。
絶縁体12は、架橋ポリエチレン等の合成樹脂が用いられている。
編組14は、直径0.2mm程度のスズメッキ軟銅線等からなる金属製の細線を織ったもので、絶縁体12との間に4本のワイヤ13が配置されている。
ここで、ワイヤ13は、編組14の端部を拡開させる拡開部材で、このような機能を有していれば、紐あるいはアラミド繊維等の繊維束を使用してもよい。
【0009】
シース15は、シールド電線10を保護するクロロプレンゴム,塩化ビニル,ポリエチレン等からなる被覆である。
シールド電線10は以上のように構成され、以下に説明するシールド電線の編組処理方法によって編組処理される。
先ず、シールド電線10の端部からシース15を所望長さ除去し、各ワイヤ13によって編組14の端部を拡開させてワイヤ13の先端を外側に折り曲げておく。
【0010】
次に、図3に示すように、電気伝導性のスズメッキを施したリン青銅等からなるキャップ17を、シールド電線10の端部側に配置する。キャップ17は、円筒部17aと大径部17bとを有し、円筒部17aの端部外周にはワイヤ13を案内する凹部17cが4箇所に設けられている。キャップ17は、円筒部17aをシールド電線10の端部側に向けて配置される。ここで、キャップ17は、導電性を有していればカーボン複合材等の導電性プラスチックを使用してもよい。
【0011】
次いで、各凹部17cに、対応するワイヤ13をそれぞれ当接させながら、円筒部17aを絶縁体12に沿って押し込む。すると、編組14は、押し込まれる円筒部17aによって4本のワイヤ13と共に均一に押し広げられる。
このようにして、キャップ17を所望位置まで押し込むと、図4及び図5に示すように、キャップ17が絶縁体12と編組14との間に挿入され、編組14と電気的に接続される。
【0012】
このように、本発明方法においては、シールド電線10の端部からキャップ17を絶縁体12に沿って押し込むだけで、従来のように編組14を折り返すことなく編組14が簡単に押し広げられ、編組14とキャップ17とが電気的に接続される。しかも、本発明方法においては、キャップ17を絶縁体12に沿って押し込むだけなので、編組14がばらけることがなく、シールド電線10の編組処理の品質が均一になるうえ、処理作業を機械を用いて自動化することも可能となる。
【0013】
ここで、シールド電線10は、図6に示すように、4本のワイヤ13が絶縁体12に螺旋状に巻き付けられていてもよい。この場合、キャップ17は、円筒部17aを絶縁体12に沿ってねじ込むようにして押し込む。
また、ワイヤ13は、複数本であることは必須であるが、編組14を均一に押し広げることができれば、本数は特に限定されず、2本あるいは3本又は4本以上であってもよい。
【0014】
更に、キャップ17は、円筒部17aから大径部17bに亘ってテーパ状あるいは曲面状に拡開する形状にすると、編組14がより一層均一に押し広げられると共に、絶縁体12に沿って押し込む操作が容易になる。
尚、上記実施形態は、シールド電線の場合について説明したが、本発明はシールドケーブルの場合にも適用可能なことは言うまでもない。
【0015】
【発明の効果】
請求項1乃至6の発明によれば、編組処理の作業性に優れ、処理品質が均一化でき、編組処理を自動化することが可能なシールド電線とその編組処理方法を提供することができる。

In a conventional shielded electric wire, for example, a shielded electric wire 1 shown in FIG. 7, an insulator 3, a braid 4 woven with metal fine wires, and a sheath 5 are arranged in this order on the outer periphery of a conductor 2 made of a stranded wire.
For example, when the shielded electric wire 1 is used for wiring of an electric vehicle, it is necessary to take measures against electromagnetic shielding from the viewpoint of electromagnetic compatibility (EMC: electro-magnetic compatibility). The braid 4 removed and exposed is shielded. In such a case, the conventional shielded electric wire 1 is arranged in the vicinity of the boundary between the braid 4 and the sheath 5 with a cap 7 made of an electrically conductive metal that has been attached in advance, as shown in FIGS. The braid 4 and the cap 7 are electrically connected by folding the braid 4 over the cap 7.

By the way, since the braid 4 is made of woven metal thin wires made of tin-plated annealed copper wire or the like, there is a problem in that the work of folding is troublesome and troublesome, and is scattered when folded. In this case, if the braid 4 is separated, the braid 4 and the cap 7 of the shielded electric wire 1 are not in uniform contact with each other, and the quality of the braiding process becomes non-uniform. Moreover, since the shielded electric wire 1 folds the braid 4 and performs the braiding process, it is difficult to automate the processing operation using a machine.
[0004]
The present invention has been made in view of the above points, and provides a shielded electric wire excellent in workability of the braiding process, uniform processing quality, and capable of automating the braiding process, and its braiding processing method. Objective.
[0005]
[Means for Solving the Problems]

It is set as the structure by which two or more are arrange | positioned.
Further, in order to achieve the above object, in the method for braiding a shielded wire according to the present invention, an insulator, a braid, and a sheath are arranged on the outer periphery of the conductor, and the braid is expanded between the insulator and the braid. A plurality of spreading members to be spread, the braiding of the shield wire end portion is widened by the plurality of spreading members, and a conductive member is attached from the shield wire end portion side to the braid. In this configuration, the conductive member is electrically connected.
[0006]
Preferably, the spreading member is a wire, and the wire is spirally wound around the insulator.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment according to the shielded electric wire and the braiding processing method of the present invention will be described in detail with reference to FIGS. 1 to 6.
As shown in FIGS. 1 and 2, the shielded electric wire 10 includes an insulator 12, four wires 13, a braid 14, and a sheath 15 arranged in this order on the outer periphery of the conductor 11.
[0008]
The conductor 11 is a stranded wire obtained by twisting a plurality of strands.
The insulator 12 is made of a synthetic resin such as cross-linked polyethylene.
The braid 14 is a woven metal thin wire made of tin-plated annealed copper wire having a diameter of about 0.2 mm, and four wires 13 are arranged between the insulator 12 and the braid 14.
Here, the wire 13 is an expanding member that expands the end portion of the braid 14, and a fiber bundle such as a string or an aramid fiber may be used as long as it has such a function.
[0009]
The sheath 15 is a coating made of chloroprene rubber, vinyl chloride, polyethylene or the like that protects the shielded electric wire 10.
The shielded electric wire 10 is configured as described above, and is braided by the shielded electric wire braiding method described below.
First, the sheath 15 is removed from the end portion of the shielded electric wire 10 by a desired length, the end portion of the braid 14 is expanded by each wire 13, and the tip end of the wire 13 is bent outward.
[0010]
Next, as shown in FIG. 3, a cap 17 made of phosphor bronze or the like subjected to electrically conductive tin plating is disposed on the end side of the shielded electric wire 10. The cap 17 has a cylindrical portion 17a and a large diameter portion 17b, and four concave portions 17c for guiding the wire 13 are provided on the outer periphery of the end portion of the cylindrical portion 17a. The cap 17 is disposed with the cylindrical portion 17 a facing the end side of the shielded electric wire 10. Here, as long as the cap 17 has conductivity, a conductive plastic such as a carbon composite material may be used.
[0011]
Next, the cylindrical portion 17 a is pushed along the insulator 12 while the corresponding wire 13 is brought into contact with each concave portion 17 c. Then, the braid 14 is uniformly spread together with the four wires 13 by the cylindrical portion 17a to be pushed.
When the cap 17 is pushed to a desired position in this way, the cap 17 is inserted between the insulator 12 and the braid 14 and electrically connected to the braid 14 as shown in FIGS. 4 and 5.
[0012]
In this way, in the method of the present invention, the braid 14 can be easily spread without folding the braid 14 as in the prior art by simply pushing the cap 17 along the insulator 12 from the end of the shielded electric wire 10. 14 and the cap 17 are electrically connected. Moreover, in the method of the present invention, the cap 17 is only pushed along the insulator 12, so that the braid 14 does not come apart, the quality of the braiding process of the shielded electric wire 10 becomes uniform, and the processing work is performed using a machine. Can also be automated.
[0013]
Here, in the shielded electric wire 10, four wires 13 may be spirally wound around the insulator 12 as shown in FIG. 6. In this case, the cap 17 is pushed in such that the cylindrical portion 17 a is screwed along the insulator 12.
The number of wires 13 is indispensable, but the number is not particularly limited as long as the braid 14 can be uniformly spread, and may be two, three, or four or more.
[0014]
Further, when the cap 17 has a shape that expands in a tapered shape or a curved surface from the cylindrical portion 17a to the large-diameter portion 17b, the braid 14 is further uniformly spread and pushed along the insulator 12. Becomes easier.
In addition, although the said embodiment demonstrated the case of a shielded electric wire, it cannot be overemphasized that this invention is applicable also to the case of a shielded cable.
[0015]
