Description

本発明はシールド線および該シールド線の形成方法に関し、特に、シールド層をコア線の外周に密着させて安定したシールド性能を得るものである。   The present invention relates to a shielded wire and a method for forming the shielded wire, and particularly to obtain a stable shielding performance by bringing a shield layer into close contact with the outer periphery of a core wire.

自動車に搭載される電子制御機器が急増しており、電子制御ユニットへセンサ、スイッチ等から検出信号を入力する信号線、および該電子制御ユニットから電子制御機器へ制御信号を出力する信号線として、ノイズ除去機能を有するシールド線が用いられている。   Electronic control devices mounted on automobiles are rapidly increasing, as signal lines for inputting detection signals from sensors, switches, etc. to the electronic control unit, and signal lines for outputting control signals from the electronic control unit to the electronic control device, A shielded wire having a noise removal function is used.

該シールド線の一種として、特開２０００−２５１５４８号公報で、図８（Ａ）（Ｂ）（Ｃ）に示すように、コア線１００とドレン線１０１とを平行配線し、該コア線とドレン線の集束体の外周に金属箔テープ１０２を螺旋状に巻き付けてシールド層を形成し、さらに、段落００２６に記載されているように、金属箔テープの外周に絶縁テープが巻き付けられている。前記ドレン線１０１は絶縁被覆層を剥離して芯線１０１ａを露出させ、該芯線１０１ａを金属箔テープ１０２に接触させると共に端末に接続した端子Ｔをアース接続している。   As a kind of the shield wire, as shown in FIGS. 8 (A), (B), and (C), in Japanese Patent Laid-Open No. 2000-251548, a core wire 100 and a drain wire 101 are wired in parallel, and the core wire and the drain wire are connected. A metal foil tape 102 is spirally wound around the outer periphery of the wire focusing body to form a shield layer. Further, as described in paragraph 0026, an insulating tape is wound around the outer periphery of the metal foil tape. The drain wire 101 peels off the insulating coating layer to expose the core wire 101a, the core wire 101a is brought into contact with the metal foil tape 102, and the terminal T connected to the terminal is grounded.

特開２０００−２５１５４８号公報JP 2000-251548 A

特許文献１に記載のシールド線および、この種の金属箔をコア線およびドレン線の外周に巻き付けてシールド層を形成しているシールド線では、金属箔テープをコア線およびドレン線の外周に巻き付ける際に十分な接触圧が得られにくく、そのため、コア線やドレン線の外周面より金属箔テープが浮き上がって空隙が発生し易い問題がある。さらに、図８（Ｃ）に示すように、ドレン線１０１と金属箔テープ１０２の接触が線接触あるいは面接触となっても接触面積が小さく、安定したシールド性能を得にくい問題がある。   In the shield wire described in Patent Document 1 and a shield wire in which this type of metal foil is wound around the outer periphery of the core wire and the drain wire to form a shield layer, the metal foil tape is wound around the outer periphery of the core wire and the drain wire. In such a case, it is difficult to obtain a sufficient contact pressure. Therefore, there is a problem that the metal foil tape is lifted from the outer peripheral surface of the core wire or the drain wire, and a void is easily generated. Further, as shown in FIG. 8C, there is a problem that even if the contact between the drain wire 101 and the metal foil tape 102 becomes a line contact or a surface contact, the contact area is small and it is difficult to obtain a stable shielding performance.

本発明は前記問題を解消せんとするもので、金属箔テープがコア線およびドレン線の外周面に隙間なく接触して巻き付けられようにし、特に、ドレン線の全周面に金属箔テープを接触できるように巻き付けて接触面積を増加し、安定したシールド性能が得られるようにすることを課題としている。   The present invention intends to solve the above problem, and allows the metal foil tape to be wound around the outer peripheral surface of the core wire and the drain wire without any gap, and in particular, to contact the metal foil tape to the entire peripheral surface of the drain wire. It is an object to increase the contact area by winding as much as possible so that stable shielding performance can be obtained.

前記課題を解決するため、本発明は、芯線を絶縁樹脂層で被覆したコア線と、１本のドレン線と、該コア線とドレン線の外周長さの加算値よりも幅広とした金属箔テープからなるシールドテープと、絶縁樹脂テープとからなり、
前記コア線とドレン線とが前記シールドテープを挟んだ状態でツイストされていると共に、該コア線とドレン線の外周に前記ツイストされたシールドテープが巻き付けられて被覆されており、さらに、前記外周に巻き付けられたシールドテープの外周に前記絶縁樹脂テープが巻き付けられていることを特徴とするシールド線を提供している。 In order to solve the above-mentioned problems, the present invention provides a core wire in which a core wire is covered with an insulating resin layer, a single drain wire, and a metal foil that is wider than the added value of the outer peripheral lengths of the core wire and the drain wire. It consists of a shield tape made of tape and an insulating resin tape,
The core wire and the drain wire are twisted in a state of sandwiching the shield tape, and the twisted shield tape is wound around and coated on the outer periphery of the core wire and the drain wire. A shielded wire is provided in which the insulating resin tape is wound around an outer periphery of a shield tape wound around.

前記コア線は１本でも良いし、前記図８に示す従来例と同様に３本等の複数本でもよい。
また、シールドテープはコア線とドレン線の全長に沿って配置し、シールドテープを挟んでコア線とドレン線とを全長にわたってツイストすることが好ましい。特に、コア線がノイズ発生電線である場合には全長にわたってシールド層を設け、外部へのノイズを遮断することが好ましい。 The number of core wires may be one, or a plurality of core wires such as three may be used as in the conventional example shown in FIG.
The shield tape is preferably disposed along the entire length of the core wire and the drain wire, and the core wire and the drain wire are twisted over the entire length with the shield tape interposed therebetween. In particular, when the core wire is a noise generating electric wire, it is preferable to provide a shield layer over the entire length to block noise to the outside.

さらに、シールドテープをコア線とドレン線との全長にわたって配置するが、ノイズを受ける領域で部分的にツイストしてもよい。あるいはノイズを受ける領域のみ、コア線に沿ってドレン線およびシールドテープを配置してツイストして部分的にシールド線としてもよい。この場合、シールド線領域と非シールド線領域とを長さ方向に混在させた電線とすることができる。   Furthermore, although the shield tape is disposed over the entire length of the core wire and the drain wire, it may be partially twisted in a region that receives noise. Alternatively, only in the area that receives noise, a drain line and a shield tape may be arranged along the core line and twisted to partially form a shield line. In this case, an electric wire in which a shielded wire region and a non-shielded wire region are mixed in the length direction can be obtained.

前記金属箔テープはアルミ箔テープ、銅箔テープ等が用いられる。
また、絶縁樹脂テープは内周面に粘着剤が塗布された塩化ビニルテープ、ポリエチレンテレフタレート等が用いられる。 As the metal foil tape, an aluminum foil tape, a copper foil tape or the like is used.
As the insulating resin tape, a vinyl chloride tape, polyethylene terephthalate or the like having an inner peripheral surface coated with an adhesive is used.

前記本発明のシールド線の形成方法として、前記コア線とドレン線との間に前記シールドテープを挟んだ状態でコア線とドレン線とをツイストして、該シールドテープをコア線およびドレン線の全外周面に巻き付け、
その後、前記シールドテープの外周に、内面に粘着剤が塗布された絶縁樹脂テープを巻き付けているシールド線の形成方法を提供している。 As a method of forming the shield wire of the present invention, the core wire and the drain wire are twisted in a state where the shield tape is sandwiched between the core wire and the drain wire, and the shield tape is used for the core wire and the drain wire. Wrap around the entire outer surface,
Thereafter, a method of forming a shield wire is provided in which an insulating resin tape having an inner surface coated with an adhesive is wound around the outer periphery of the shield tape.

より詳細には、前記コア線が１本の場合は、該コア線およびドレン線の中心軸線と前記シールドテープの幅方向の中心線を一致させてツイストしている。
前記シールドテープの外周面への絶縁樹脂テープの巻き付けは、すし巻き、拝み巻、螺旋巻きのいずれでも良い。 More specifically, when the number of the core wires is one, the central axes of the core wires and the drain wires are twisted so that the center lines in the width direction of the shield tape coincide with each other.
The insulating resin tape may be wound around the outer peripheral surface of the shield tape by any of sushi winding, worship winding, and spiral winding.

前記ツイスト時に前記シールドテープがコア線およびドレン線の間に隙間が発生しないように面接触させてツイストし、かつ、前記シールドテープの外周面に前記絶縁樹脂テープを隙間なく面接触させて巻き付けている。   Twist the shield tape so that there is no gap between the core wire and the drain wire during twisting, and twist the insulating resin tape around the outer peripheral surface of the shield tape without any gap. Yes.

本発明のシールド線は、前記のように、１本のコア線または集束した複数本のコア線と、１本のドレン線とを金属箔テープを挟んでツイストして（捩って）いることにより、コア線の全外周面に金属箔テープの幅方向の一側部を巻き付けることができると共に、該金属箔テープの他側部を１本のドレン線の全外周面に巻き付けることができる。かつ、これらコア線とドレン線を金属箔テープを挟んで捩っているために、金属箔テープをコア線およびドレン線にそれぞれ強く密着させて巻き付けることができ、コア線およびドレン線に対する金属箔テープの接触圧を十分に確保でき、金属箔テープが浮き上がって隙間が生じるのを防止できる。
さらに、該金属箔テープの外周面に絶縁樹脂テープを巻き付けているため、金属箔テープと最外周のシースとして機能する絶縁樹脂テープとの間にも隙間が発生せず、金属箔テープをコア線およびドレン線の外周面に隙間なく密着させることができる。 As described above, the shield wire of the present invention is formed by twisting (twisting) one core wire or a plurality of converged core wires and one drain wire with a metal foil tape interposed therebetween. Thus, one side of the metal foil tape in the width direction can be wound around the entire outer peripheral surface of the core wire, and the other side of the metal foil tape can be wound around the entire outer peripheral surface of one drain wire. In addition, since the core wire and the drain wire are twisted with the metal foil tape interposed therebetween, the metal foil tape can be tightly wound around the core wire and the drain wire, respectively, and the metal foil for the core wire and the drain wire can be wound. A sufficient contact pressure of the tape can be secured, and the metal foil tape can be prevented from floating and causing a gap.
In addition, since the insulating resin tape is wound around the outer peripheral surface of the metal foil tape, no gap is generated between the metal foil tape and the insulating resin tape functioning as the outermost sheath, and the metal foil tape is a core wire. In addition, the drain wire can be closely adhered to the outer peripheral surface of the drain wire.

前記のように、本発明のシールド線は、コア線とドレン線の間に金属箔テープを挟んでツイストした構成としているため、金属箔テープからなるシールド層はコア線の外周面およびドレン線の外周面にそれぞれ大きな接触面積で且つ十分な接触圧で接触させることができ、シールド性能を安定させることができる利点を有する。   As described above, since the shield wire of the present invention has a configuration in which the metal foil tape is twisted between the core wire and the drain wire, the shield layer made of the metal foil tape has the outer peripheral surface of the core wire and the drain wire. The outer peripheral surface can be brought into contact with each other with a large contact area and sufficient contact pressure, and the shield performance can be stabilized.

以下、本発明の実施形態を図面を参照して説明する。
図１乃至図４に第一実施形態を示す。
第一実施形態のシールド線１は、１本のコア線２と、１本のドレン線３と、金属箔テープからなるシールドテープ４と、絶縁樹脂テープ５とからなる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a first embodiment.
The shield wire 1 according to the first embodiment includes one core wire 2, one drain wire 3, a shield tape 4 made of a metal foil tape, and an insulating resin tape 5.

コア線２は銅系金属線からなる素線をよりあわせた芯線２ａを絶縁樹脂層２ｂで被覆している。
ドレン線３は銅系金属線からなる素線のより線のみ、あるいは銅系金属線からなる単芯線のみで、絶縁樹脂層がなく、その端末にアース端子あるいはコネクタ端子が圧着できるものである。
金属箔テープからなるシールドテープ４はアルミ箔テープまたは銅箔テープからなり、本実施形態ではアルミ箔テープを用いている。図２に示すように、シールドテープ４の幅Ｗ１はコア線２の外周長さＬ１とドレン線３の外周長さＬ２との加算値以上としている（Ｗ１≧Ｌ１＋Ｌ２）。
絶縁樹脂テープ５が内面に粘着剤が塗布された塩化ビニルテープ、ポリエチレンテレフタレート等からなり、本実施形態では塩化ビニルテープからなる。 The core wire 2 is formed by covering a core wire 2a, which is a combination of strands made of a copper-based metal wire, with an insulating resin layer 2b.
The drain wire 3 is only a stranded wire made of a copper-based metal wire or only a single core wire made of a copper-based metal wire, has no insulating resin layer, and a ground terminal or a connector terminal can be crimped to the terminal.
The shield tape 4 made of a metal foil tape is made of an aluminum foil tape or a copper foil tape. In this embodiment, an aluminum foil tape is used. As shown in FIG. 2, the width W1 of the shield tape 4 is not less than the sum of the outer peripheral length L1 of the core wire 2 and the outer peripheral length L2 of the drain wire 3 (W1 ≧ L1 + L2).
The insulating resin tape 5 is made of a vinyl chloride tape, polyethylene terephthalate, etc. with an adhesive applied on the inner surface, and in the present embodiment, made of a vinyl chloride tape.

シールド線１は、コア線２とドレン線３との全長を、シールドテープ４を挟んだ状態でツイストし、コア線２の全外周面にシールドテープ４の幅方向の一側部４ａを略全面接触で巻き付け、ドレン線３の全外周面にシールドテープ４の他側部４ｂを略全面接触で巻き付けている。かつ、シールドテープ４の外周面に絶縁樹脂テープ５を拝み巻き状に巻き付けて被覆している。   The shield wire 1 is twisted over the entire length of the core wire 2 and the drain wire 3 with the shield tape 4 sandwiched between them, and the one side portion 4a in the width direction of the shield tape 4 is arranged almost on the entire outer peripheral surface of the core wire 2. The other side portion 4b of the shield tape 4 is wound around the entire outer peripheral surface of the drain wire 3 by substantially entire surface contact. In addition, the insulating resin tape 5 is wrapped around the outer peripheral surface of the shield tape 4 so as to be covered.

前記シールド線１は図３（Ａ）〜（Ｃ）に示すように形成している。
図３（Ａ）に示すように、コア線２とドレン線３とを平行に配置し、その間にシールドテープ４を配置する。其の際、各１本のコア線とドレン線３の中心線を一致させると共に、シールドテープ４の幅方向の中心線Ｗｏを一致させて、上下に重ねる。 The shield wire 1 is formed as shown in FIGS.
As shown in FIG. 3A, the core wire 2 and the drain wire 3 are disposed in parallel, and the shield tape 4 is disposed therebetween. At that time, each one core line and the center line of the drain line 3 are made to coincide with each other, and the center line Wo in the width direction of the shield tape 4 is made to coincide with each other and overlap each other.

ついで、図３（Ｂ）に示すように、コア線２、ドレン線３、シールドテープ４を一体として長さ方向の一端側から捩って（即ち、ツイストして）、シールドテープ４を挟んだ状態でコア線２とドレン線３とをツイスト電線とする。
このツイスト作業は、コア線２とドレン線３とを把持してツイスト線とすると、シールドテープ４がツイスト線となるコア線２とドレン線３の外周に巻き込まれる。それにより、図１（Ｂ）（Ｃ）に示すように、コア線２の全外周面にシールドテープ４の一側部４ａが巻き付けられると共に、ドレン線３の全外周面にシールドテープ４の他側部４ｂが巻き付けられる。これにより、コア線２とドレン線３のいずれも、その全外周面がシールドテープ４で被覆されることになる。
かつ、ツイスト作業時に、コア線２とドレン線３の外周面からシールドテープ４が浮き上がることなく十分な捩り力でツイストし、コア線２およびドレン線３の各外周面にシールドテープを隙間なく接触させる。 Next, as shown in FIG. 3B, the core wire 2, the drain wire 3, and the shield tape 4 are integrally twisted from one end in the length direction (that is, twisted) to sandwich the shield tape 4 In this state, the core wire 2 and the drain wire 3 are twisted wires.
In this twisting operation, when the core wire 2 and the drain wire 3 are gripped to form a twisted wire, the shield tape 4 is wound around the outer periphery of the core wire 2 and the drain wire 3 that become the twisted wire. As a result, as shown in FIGS. 1B and 1C, one side portion 4a of the shield tape 4 is wound around the entire outer peripheral surface of the core wire 2, and the other of the shield tape 4 is wrapped around the entire outer peripheral surface of the drain wire 3. The side part 4b is wound. Thereby, both the core wire 2 and the drain wire 3 are covered with the shield tape 4 on the entire outer peripheral surface thereof.
In addition, during twisting operation, the shield tape 4 is twisted with sufficient torsional force without lifting up from the outer peripheral surfaces of the core wire 2 and the drain wire 3, and the shield tape is in contact with the outer peripheral surfaces of the core wire 2 and the drain wire 3 without any gaps. Let

最後に、図３（Ｃ）に示すように、ツイストして一体化したコア線２、ドレン線３、シールドテープ４の外周面、即ち、外周面に位置するシールドテープ４の外周に絶縁樹脂テープ５を拝み巻状に巻き付け、該絶縁樹脂テープ５の重ね合わせ端部を内面に塗布した粘着剤（図示せず）で固着している。これにより図１に示すシールド線１を形成している。   Finally, as shown in FIG. 3C, an insulating resin tape is provided on the outer peripheral surface of the core wire 2, the drain wire 3, and the shield tape 4 integrated by twisting, that is, on the outer periphery of the shield tape 4 positioned on the outer peripheral surface. 5 is wound in a wrinkle shape, and the overlapping end portion of the insulating resin tape 5 is fixed with an adhesive (not shown) applied to the inner surface. Thereby, the shield wire 1 shown in FIG. 1 is formed.

前記のように形成したシールド線１は、コア線２、ドレン線３の各外周面の全面がシールドテープ４で被覆され、かつ、該シールドテープ４が浮き上がることなくコア線２、ドレン線３の全外周面に接触しているため、コア線２のシールド機能を安定させることができる。   In the shield wire 1 formed as described above, the entire outer peripheral surfaces of the core wire 2 and the drain wire 3 are covered with the shield tape 4, and the core wire 2 and the drain wire 3 are not lifted up. Since it is in contact with the entire outer peripheral surface, the shield function of the core wire 2 can be stabilized.

本発明のシールド線１は長尺電線として連続的に形成し、使用時に所要長さに切断することが好ましい。
図４に示すように、所定長さのシールド線１とした後に、該シールド線１の両端末でシールドテープ４、絶縁樹脂テープ５を所要寸法剥離して、コア線２とドレン線３の端末を露出させ、コア線２では更に絶縁樹脂層２ｂを剥離して露出した芯線２ａに端子Ｔ１を接続している。また、ドレン線３の端末にも端子Ｔ２を接続している。
本発明のシールド線１は他の電線群と集束してワイヤハーネスとし、あるいはシールド線１を単独として、自動車内部に配線し、シールド線１のドレン線３をアース接続している。
なお、図８に示す従来例と同様に、コア線およびドレン線を所定長さとし、その端末に端子を圧着した状態で用いてもよい。即ち、端末に端子を取り付けたコア線とドレン線をシールドテープを挟んでツイストしてもよい。 The shield wire 1 of the present invention is preferably formed continuously as a long electric wire and cut to a required length during use.
As shown in FIG. 4, after the shield wire 1 having a predetermined length is formed, the shield tape 4 and the insulating resin tape 5 are peeled off at both ends of the shield wire 1, and the ends of the core wire 2 and the drain wire 3. In the core wire 2, the terminal T1 is connected to the exposed core wire 2a by further peeling the insulating resin layer 2b. The terminal T2 is also connected to the terminal of the drain wire 3.
The shielded wire 1 of the present invention is converged with other electric wire groups to form a wire harness, or the shielded wire 1 alone is wired inside the automobile, and the drain wire 3 of the shielded wire 1 is grounded.
Similarly to the conventional example shown in FIG. 8, the core wire and the drain wire may have predetermined lengths, and the terminal may be crimped to the terminal. That is, you may twist the core wire and drain wire which attached the terminal to the terminal on both sides of the shield tape.

図５に第二実施形態を示す。
第二実施形態ではコア線を３本としている点だけが第一実施形態との相違点である。
３本のコア線２Ａ、２Ｂ、２Ｃを重ねて集束し、１本のドレン線３とシールドテープ４を挟んでツイストし、その後、絶縁樹脂テープ５をハーフラップ巻きで巻き付けている。 他の構成および作用効果は第一実施形態と同様であるため、説明を省略する。 FIG. 5 shows a second embodiment.
In the second embodiment, the only difference from the first embodiment is that there are three core wires.
Three core wires 2A, 2B, and 2C are overlapped and converged, twisted with one drain wire 3 and shield tape 4 interposed therebetween, and then the insulating resin tape 5 is wound by half wrap winding. Other configurations and operational effects are the same as those of the first embodiment, and thus description thereof is omitted.

図６に第三実施形態を示す。
第三実施形態では、コア線２、ドレン線３の間には全長にわたってシールドテープ４を配置しているが、ノイズを受ける領域Ｘのみで、コア線２、ドレン線３およびシールドテープ４を捩り、シールドテープ４で被覆したツイスト電線としている。図示していないが、ノイズを受ける領域が複数箇所であれば、複数箇所でツイストしている。また、コア線、ドレン線、シールドテープ４には樹脂チューブやコルゲートチューブ（図示せず）をかぶせて絶縁保護している。
その後、第一実施形態と同様に、絶縁樹脂テープを巻き付けて被覆している。
該第三実施形態のシールド線は、ノイズを受ける領域のみをシールドできるシールド電線としている。 FIG. 6 shows a third embodiment.
In the third embodiment, the shield tape 4 is disposed over the entire length between the core wire 2 and the drain wire 3, but the core wire 2, the drain wire 3 and the shield tape 4 are twisted only in the region X that receives noise. The twisted electric wire covered with the shield tape 4 is used. Although not shown, if there are a plurality of regions where noise is received, twisting is performed at a plurality of locations. The core wire, drain wire, and shield tape 4 are covered with a resin tube or a corrugated tube (not shown) for insulation protection.
Thereafter, as in the first embodiment, the insulating resin tape is wound and covered.
The shielded wire of the third embodiment is a shielded electric wire that can shield only a region that receives noise.

図７に第四実施形態を示す。
第四実施形態も第三実施形態と同様にノイズを受ける領域のみをシールドし、他の領域はシールドしていない。
コア線２の全長に沿ってドレン線として被覆電線３０を配線し、ノイズを受ける部分的な領域では被覆電線３０の絶縁被覆を皮剥して芯線を露出させてドレン線３とし、かつ、金属箔テープからなるシールドテープ４を配置し、前記第一実施形態と同様にシールドテープ４を挟んだ状態でコア線２とドレン線３とをツイストし、その外周に絶縁樹脂テープ５を巻き付けている。ノイズを受ける領域以外の領域にはコア線と被覆電線３０を配線している。コア線２が複数本の場合は、前記絶縁樹脂テープ５をコア線２に結束するために延在して巻き付けてもよい。 FIG. 7 shows a fourth embodiment.
Similarly to the third embodiment, the fourth embodiment also shields only the area that receives noise, and the other areas are not shielded.
The covered electric wire 30 is wired as a drain wire along the entire length of the core wire 2, and in a partial region where noise is received, the insulation coating of the covered electric wire 30 is peeled to expose the core wire to form the drain wire 3, and the metal foil A shield tape 4 made of a tape is disposed, and the core wire 2 and the drain wire 3 are twisted with the shield tape 4 sandwiched in the same manner as in the first embodiment, and the insulating resin tape 5 is wound around the outer periphery thereof. The core wire and the covered electric wire 30 are wired in a region other than the region that receives noise. When there are a plurality of core wires 2, the insulating resin tape 5 may be extended and wound around the core wires 2.

前記第三および第四実施形態のように、コア線の全長のうち、ノイズを受ける領域が部分的である場合には、ノイズを受ける領域のみシールド電線とし、ノイズの影響を受けない領域は非シールド電線とすると、電線の重量増加、コスト増加を低減することができる。   As in the third and fourth embodiments, when the region that receives noise is partial in the entire length of the core wire, only the region that receives noise is a shielded wire, and the region that is not affected by noise is non- When a shielded electric wire is used, an increase in the weight and cost of the electric wire can be reduced.
