　最初に本開示の実施形態を列記して説明する。
　本開示のシート状導電路は、
　（１）可撓性を有するシート材と、前記シート材に固着した状態で配置された伝送路と、前記シート材に固着した状態で前記伝送路に沿うように配置されたシート状のノイズ遮蔽部材とを備え、前記シート材と前記ノイズ遮蔽部材とが、前記伝送路の長さ方向に間隔を空けた複数の固着部位において固着されている。本開示の構成によれば、ノイズ遮蔽部材がシート状をなし、ノイズ遮蔽部材を配置するためのスペースが小さくて済むので、省スペース化を実現することができる。シート材とノイズ遮蔽部材との固着部位が、伝送路の全長に亘って連続していないので、固着に要する材料コストを低減できる。 [Explanation of Embodiments of the present disclosure]
First, the embodiments of the present disclosure will be listed and described.
The sheet-shaped conductive path of the present disclosure is
(1) A flexible sheet material, a transmission line arranged in a state of being fixed to the sheet material, and a sheet-like noise shield arranged along the transmission line in a state of being fixed to the sheet material. A member is provided, and the sheet material and the noise shielding member are fixed at a plurality of fixing portions spaced apart in the length direction of the transmission line. According to the configuration of the present disclosure, the noise shielding member has a sheet shape, and the space for arranging the noise shielding member is small, so that space saving can be realized. Since the fixing portion between the sheet material and the noise shielding member is not continuous over the entire length of the transmission line, the material cost required for fixing can be reduced.
　（２）前記ノイズ遮蔽部材が、前記シート材を挟んで前記伝送路とは反対側に配置されており、前記シート材と前記ノイズ遮蔽部材との固着部位が、前記伝送路の長さ方向において５０ｍｍ以下の間隔で設定されている。この構成によれば、シート材を曲げた状態で配置しても、ノイズ遮蔽部材がシート材に対して位置ずれし難いので、ノイズ遮蔽部材と伝送路とが大きく離隔するおそれがない。これにより、良好なノイズ遮蔽効果を得ることができる。 (2) The noise shielding member is arranged on the side opposite to the transmission line with the sheet material interposed therebetween, and the fixing portion between the sheet material and the noise shielding member is in the length direction of the transmission line. It is set at intervals of 50 mm or less. According to this configuration, even if the sheet material is arranged in a bent state, the noise shielding member is unlikely to be displaced with respect to the sheet material, so that there is no possibility that the noise shielding member and the transmission line are greatly separated from each other. Thereby, a good noise shielding effect can be obtained.
　（３）（２）において、前記シート材と前記ノイズ遮蔽部材との固着部位が、前記伝送路の長さ方向において３０ｍｍ以下の間隔で設定されている。この構成によれば、シート材を曲げた状態で配置したときに、シート材からのノイズ遮蔽部材の位置ずれを確実に防止できる。これにより、ノイズ遮蔽部材の伝送路からの離隔を最小に抑え、より良好なノイズ遮蔽効果を得ることができる。 In (3) and (2), the fixing portions of the sheet material and the noise shielding member are set at intervals of 30 mm or less in the length direction of the transmission line. According to this configuration, when the sheet material is arranged in a bent state, it is possible to reliably prevent the noise shielding member from being displaced from the sheet material. As a result, the separation of the noise shielding member from the transmission line can be minimized, and a better noise shielding effect can be obtained.
　（４）前記シート材と前記ノイズ遮蔽部材との固着強度が１０Ｎ以上であることが好ましい。この構成において、固着強度は、固着状態のノイズ遮蔽部材をシート材から引き剥がすのに要する引張力である。この構成によれば、シート材とノイズ遮蔽部材との固着強度の信頼性が高いので、シート材を曲げたときの曲率半径が小さくても、ノイズ遮蔽部材がシート材から剥がれるおそれがない。 (4) It is preferable that the adhesion strength between the sheet material and the noise shielding member is 10 N or more. In this configuration, the fixing strength is the tensile force required to peel off the noise shielding member in the fixed state from the sheet material. According to this configuration, since the adhesion strength between the sheet material and the noise shielding member is highly reliable, there is no possibility that the noise shielding member will be peeled off from the sheet material even if the radius of curvature when the sheet material is bent is small.
　（５）前記ノイズ遮蔽部材が、磁性体層と、前記磁性体層を前記シート材に固着させる溶着層とを積層した形態であり、前記溶着層が、前記伝送路の最外周層を構成するシースと同じ材料であることが好ましい。この構成によれば、シート材に対する伝送路の溶着と、シート材に対するノイズ遮蔽部材の溶着とを、同時に行うことができる。 (5) The noise shielding member is in the form of laminating a magnetic material layer and a welding layer for fixing the magnetic material layer to the sheet material, and the welding layer constitutes the outermost outermost layer of the transmission line. It is preferably made of the same material as the sheath. According to this configuration, welding of the transmission line to the sheet material and welding of the noise shielding member to the sheet material can be performed at the same time.

In the following description, it is assumed that the sheet material 10 is arranged horizontally for convenience.
　図２に示すように、上下一対のシート材１０の間には、第１伝送路２０と第２伝送路３０が上下から挟まれた状態で水平に配索されている。図１に示すように、第１伝送路２０は、幹線用配線部１１に沿って配索された幹線部２１と、支線用配線部１２に沿って配索された支線部２２とを有する。図１では省略するが、第２伝送路３０も、幹線用配線部１１に沿って配索された幹線部（図示省略）と、支線用配線部１２に沿って配索された支線部（図示省略）とを有する。 As shown in FIG. 2, between the upper and lower pair of sheet materials 10, the first transmission line 20 and the second transmission line 30 are horizontally arranged so as to be sandwiched from above and below.

Omitted) and.
　第１伝送路２０は、通信回路の導電路であるため、同軸ケーブルで構成されている。図３に示すように、同軸ケーブルは、導体２４と、導体２４を包囲する筒状の絶縁体２５と、絶縁体２５の外周を包囲する編組線等からなるシールド層２６と、シールド層２６を包囲する円筒形のシース２７とを有する。シース２７は、ＰＶＣ（ポリ塩化ビニル）からなる。 Since the first transmission line 20 is a conductive line of a communication circuit, it is composed of a coaxial cable. As shown in FIG. 3, the coaxial cable includes a conductor 24, a cylindrical insulator 25 surrounding the conductor 24, a shield layer 26 composed of a braided wire or the like surrounding the outer circumference of the insulator 25, and a shield layer 26. It has a cylindrical sheath 27 that surrounds it. The sheath 27 is made of PVC (polyvinyl chloride).
　第１伝送路２０は、例えばルーフに取り付けた外部アンテナ（図示省略）で受信した信号を１Ｇｂｐｓ以上の高速度でＥＣＵに伝送する。第１伝送路２０には１ＧＨｚ以上の高周波の電流が流れる。高周波電流は、コモンモードノイズ等の発生原因となる。そのため、第１伝送路２０に関しては、電磁ノイズ対策として同軸ケーブルを用いた上で、更に、ノイズ対策の信頼性を高めるためにノイズ遮蔽部材４０を設けている。 The first transmission line 20 transmits, for example, a signal received by an external antenna (not shown) attached to the roof to the ECU at a high speed of 1 Gbps or more. A high frequency current of 1 GHz or more flows through the first transmission line 20. High-frequency current causes common mode noise and the like. Therefore, regarding the first transmission line 20, a coaxial cable is used as a countermeasure against electromagnetic noise, and a noise shielding member 40 is provided in order to further improve the reliability of the noise countermeasure.
　第２伝送路３０は、芯線３１の外周を、円筒形の絶縁被覆３２で包囲したものである。絶縁被覆３２は、第１伝送路２０のシース２７と同じく、ＰＶＣ（ポリ塩化ビニル）からなる。第２伝送路３０は、電力供給等の導電路として用いられるものである。第２伝送路３０に関しては、電磁ノイズ対策は不要である。 The second transmission line 30 surrounds the outer circumference of the core wire 31 with a cylindrical insulating coating 32. The insulating coating 32 is made of PVC (polyvinyl chloride) like the sheath 27 of the first transmission line 20. The second transmission line 30 is used as a conductive line for power supply and the like. No measures against electromagnetic noise are required for the second transmission line 30.
　シート材１０の幹線用配線部１１においては、第１伝送路２０の幹線部２１と第２伝送路３０の幹線部（図示省略）が互いに平行に並ぶように配索されている。支線用配線部１２においては、第１伝送路２０の支線部２２と第２伝送路３０の支線部（図示省略）とが互いに平行に並ぶように配置される形態か、第１伝送路２０の支線部２２のみが配索される形態か、第２伝送路３０の支線部（図示省略）のみが配索される形態のいずれかが採用される。 In the trunk line wiring portion 11 of the sheet material 10, the trunk line portion 21 of the first transmission line 20 and the trunk line portion (not shown) of the second transmission line 30 are arranged so as to be arranged in parallel with each other. In the branch line wiring portion 12, the branch line portion 22 of the first transmission line 20 and the branch line portion (not shown) of the second transmission line 30 are arranged so as to be arranged in parallel with each other, or the first transmission line 20 Either a form in which only the branch line portion 22 is laid out or a form in which only the branch line portion (not shown) of the second transmission line 30 is laid out is adopted.
　ノイズ遮蔽部材４０は、可撓性を有し、帯状に細長く延びたシート状の材料である。ノイズ遮蔽部材４０の幅寸法は、第１伝送路２０の直径寸法よりも大きい。図１，４に示すように、ノイズ遮蔽部材４０は、第１伝送路２０の幹線部２１及び支線部２２に沿って細長く途中で分岐した形状をなしている。図３に示すように、ノイズ遮蔽部材４０は、薄膜状の磁性体層４１と、薄膜状の溶着層４２と、薄膜状の保護層４３とを順に積層した三層構造のものである。 The noise shielding member 40 is a flexible, strip-shaped sheet-like material. The width dimension of the noise shielding member 40 is larger than the diameter dimension of the first transmission line 20. As shown in FIGS. 1 and 4, the noise shielding member 40 has a shape that is elongated and branched in the middle along the trunk line portion 21 and the branch line portion 22 of the first transmission line 20. As shown in FIG. 3, the noise shielding member 40 has a three-layer structure in which a thin-film magnetic layer 41, a thin-film welding layer 42, and a thin-film protective layer 43 are laminated in this order.
　磁性体層４１は、フェライト、電磁純鉄、けい素鉄等の軟質磁性材からなる粉体を合成樹脂内に分散して混合したものである。磁性体層４１は、磁気損失により、高周波の電磁ノイズを熱に変換して消滅させる。磁性体層４１は、溶着層４２と保護層４３とに挟まれている。なお、図３においては、便宜上、磁性体層４１、溶接層及び保護層４３の厚さを、誇張して描いている。溶着層４２は、第１伝送路２０のシース２７及び第２伝送路３０の絶縁被覆３２と同じく、ＰＶＣ（ポリ塩化ビニル）からなる。保護層４３は、ＰＥＴ（ポリエチレンテレフタレート）からなる。 The magnetic material layer 41 is a mixture of powders made of a soft magnetic material such as ferrite, electromagnetic pure iron, and silicon iron dispersed in a synthetic resin. The magnetic material layer 41 converts high-frequency electromagnetic noise into heat and eliminates it due to magnetic loss. The magnetic material layer 41 is sandwiched between the welding layer 42 and the protective layer 43. In FIG. 3, for convenience, the thicknesses of the magnetic layer 41, the welding layer, and the protective layer 43 are exaggerated. The welding layer 42 is made of PVC (polyvinyl chloride) like the sheath 27 of the first transmission line 20 and the insulating coating 32 of the second transmission line 30. The protective layer 43 is made of PET (polyethylene terephthalate).
　シート状導電路Ａを製造する際には、水平な治具（図示省略）の上に第１伝送路２０と第２伝送路３０を、所定の配索経路の沿うように配置し、その上に、一方のシート材１０を載せ、このシート材１０の上に一方のノイズ遮蔽部材４０を重ねるように載置する。このとき、ノイズ遮蔽部材４０は、第１伝送路２０の配索経路のみに沿うように配置する。換言すると、ノイズ遮蔽部材４０は、第１伝送路２０と第２伝送路３０のうち第１伝送路２０の配索経路のみを覆うように配置される。この状態で、超音波溶着を行う。超音波溶着は、第１伝送路２０の配索方向において間隔を空けた複数の固着部位Ｐ（図４参照）と、第２伝送路３０の配索方向において間隔を空けた複数の固着部位（図示省略）とで実行される。 When manufacturing the sheet-shaped conductive path A, the first transmission line 20 and the second transmission line 30 are arranged along a predetermined wiring path on a horizontal jig (not shown), and above the first transmission line 20 and the second transmission line 30. One sheet material 10 is placed on the sheet material 10, and one noise shielding member 40 is placed on the sheet material 10 so as to be overlapped with the sheet material 10. At this time, the noise shielding member 40 is arranged so as to be along only the wiring path of the first transmission line 20. In other words, the noise shielding member 40 is arranged so as to cover only the wiring path of the first transmission line 20 of the first transmission line 20 and the second transmission line 30. In this state, ultrasonic welding is performed. In ultrasonic welding, a plurality of anchoring sites P (see FIG. 4) spaced apart in the wiring direction of the first transmission line 20 and a plurality of bonding sites spaced apart in the wiring direction of the second transmission line 30 (see FIG. 4). It is executed with (not shown).
　第１伝送路２０の固着部位Ｐにおける超音波溶着工程では、シート材１０と第１伝送路２０のシース２７とが溶着されると同時に、ノイズ遮蔽部材４０の溶着層４２とシート材１０とが溶着される。また、第２伝送路３０の固着部位（図示省略）における超音波溶着工程では、シート材１０と第２伝送路３０の絶縁被覆３２とが溶着される。 In the ultrasonic welding step at the fixed portion P of the first transmission line 20, the sheet material 10 and the sheath 27 of the first transmission line 20 are welded, and at the same time, the welding layer 42 of the noise shielding member 40 and the sheet material 10 are welded together. It is welded. Further, in the ultrasonic welding step at the fixed portion (not shown) of the second transmission line 30, the sheet material 10 and the insulating coating 32 of the second transmission line 30 are welded.
　上記のようにして一体化した第１伝送路２０と第２伝送路３０と一方のシート材１０と一方のノイズ遮蔽部材４０を、上下反転させる。そして、第１伝送路２０と第２伝送路３０の上に他方のシート材１０を載せ、このシート材１０の上に他方のノイズ遮蔽部材４０を重ねるように載置する。このときも、他方のノイズ遮蔽部材４０は、第１伝送路２０の配索経路のみに沿うように配置する。換言すると、他方のノイズ遮蔽部材４０は、第１伝送路２０と第２伝送路３０のうち第１伝送路２０の配索経路のみを覆うように配置される。この後、上記と同様に、複数の固着部位Ｐにおいて超音波溶着を行い、第１伝送路２０と第２伝送路３０と他方のシート材１０と他方のノイズ遮蔽部材４０を固着して一体化させる。以上により、シート状導電路Ａが完成する。 The first transmission line 20, the second transmission line 30, one sheet material 10, and one noise shielding member 40 integrated as described above are turned upside down. Then, the other sheet material 10 is placed on the first transmission line 20 and the second transmission line 30, and the other noise shielding member 40 is placed on the sheet material 10 so as to be overlapped with each other. Also at this time, the other noise shielding member 40 is arranged so as to be along only the wiring path of the first transmission line 20. In other words, the other noise shielding member 40 is arranged so as to cover only the wiring path of the first transmission line 20 of the first transmission line 20 and the second transmission line 30. After that, ultrasonic welding is performed at the plurality of fixing portions P in the same manner as described above, and the first transmission line 20, the second transmission line 30, the other sheet material 10 and the other noise shielding member 40 are fixed and integrated. Let me. As described above, the sheet-shaped conductive path A is completed.
　本実施例１のシート状導電路Ａは、可撓性を有するシート材１０と、シート材１０に固着した状態で配置された第１伝送路２０と、シート材１０に固着した状態で第１伝送路２０に沿うように配置されたシート状のノイズ遮蔽部材４０とを備えている。シート材１０とノイズ遮蔽部材４０は、第１伝送路２０の長さ方向に間隔を空けた複数の固着部位Ｐのみにおいて固着されている。この構成によれば、ノイズ遮蔽部材４０がシート状をなし、ノイズ遮蔽部材４０を配置するためのスペースが小さくて済むので、省スペース化を実現することができる。シート材１０とノイズ遮蔽部材４０が固着されるのは、第１伝送路２０の長さ方向に間隔を空けた複数箇所だけである。シート材１０とノイズ遮蔽部材４０との固着部位Ｐが、第１伝送路２０の全長に亘って連続していないので、固着に要する材料コストを低減できる。 The sheet-shaped conductive path A of the first embodiment has a flexible sheet material 10, a first transmission path 20 arranged in a state of being fixed to the sheet material 10, and a first state of being fixed to the sheet material 10. It includes a sheet-shaped noise shielding member 40 arranged along the transmission line 20. The sheet material 10 and the noise shielding member 40 are fixed only at a plurality of fixing portions P spaced apart from each other in the length direction of the first transmission line 20. According to this configuration, the noise shielding member 40 has a sheet shape, and the space for arranging the noise shielding member 40 can be small, so that space saving can be realized. The sheet material 10 and the noise shielding member 40 are fixed only at a plurality of locations spaced apart from each other in the length direction of the first transmission line 20. Since the fixing portion P between the sheet material 10 and the noise shielding member 40 is not continuous over the entire length of the first transmission line 20, the material cost required for fixing can be reduced.
　第１伝送路２０はシート材１０の片面のみに固着されている。ノイズ遮蔽部材４０は、シート材１０を挟んで第１伝送路２０とは反対側に配置されている。シート材１０とノイズ遮蔽部材４０との固着部位Ｐは、第１伝送路２０の長さ方向において５０ｍｍ以下の間隔を空けて設定されている。この構成によれば、シート材１０を曲げた状態で配置しても、ノイズ遮蔽部材４０がシート材１０に対して位置ずれし難いので、ノイズ遮蔽部材４０と第１伝送路２０とが大きく離隔するおそれがない。これにより、良好なノイズ遮蔽効果を得ることができる。 The first transmission line 20 is fixed to only one side of the sheet material 10. The noise shielding member 40 is arranged on the side opposite to the first transmission line 20 with the sheet material 10 interposed therebetween. The fixed portion P between the sheet material 10 and the noise shielding member 40 is set at a distance of 50 mm or less in the length direction of the first transmission line 20. According to this configuration, even if the sheet material 10 is arranged in a bent state, the noise shielding member 40 is unlikely to be displaced with respect to the sheet material 10, so that the noise shielding member 40 and the first transmission line 20 are greatly separated from each other. There is no risk of doing so. Thereby, a good noise shielding effect can be obtained.
　シート材１０とノイズ遮蔽部材４０との固着部位Ｐは、第１伝送路２０の長さ方向において３０ｍｍ以下の間隔を空けて設定することが好ましい。この間隔設定によれば、シート材１０を曲げた状態で配置したときに、シート材１０からのノイズ遮蔽部材４０の位置ずれを確実に防止できる。これにより、ノイズ遮蔽部材４０の第１伝送路２０からの離隔を最小に抑え、より良好なノイズ遮蔽効果を得ることができる。 It is preferable that the fixing portion P between the sheet material 10 and the noise shielding member 40 is set at a distance of 30 mm or less in the length direction of the first transmission line 20. According to this interval setting, when the sheet material 10 is arranged in a bent state, the misalignment of the noise shielding member 40 from the sheet material 10 can be reliably prevented. As a result, the separation of the noise shielding member 40 from the first transmission line 20 can be minimized, and a better noise shielding effect can be obtained.
　シート材１０とノイズ遮蔽部材４０との固着強度は、１０Ｎ以上である。固着強度は、固着状態のノイズ遮蔽部材４０をシート材１０から引き剥がすのに要する引張力である。固着強度を１０Ｎ以上としたことにより、シート材１０とノイズ遮蔽部材４０との固着強度の信頼性が高くなっている。したがって、シート材１０を曲げたときの曲率半径が小さくても、ノイズ遮蔽部材４０がシート材１０から剥がれるおそれがない。 The adhesion strength between the sheet material 10 and the noise shielding member 40 is 10 N or more. The fixing strength is a tensile force required to peel off the noise shielding member 40 in the fixed state from the sheet material 10. By setting the fixing strength to 10 N or more, the reliability of the fixing strength between the sheet material 10 and the noise shielding member 40 is high. Therefore, even if the radius of curvature when the sheet material 10 is bent is small, there is no possibility that the noise shielding member 40 will be peeled off from the sheet material 10.
　ノイズ遮蔽部材４０は、磁性体層４１と、磁性体層４１をシート材１０に固着させる溶着層４２とを積層した形態である。溶着層４２は、第１伝送路２０の最外周層を構成するシース２７と同じ材料である。この構成によれば、シート材１０に対する第１伝送路２０の溶着と、シート材１０に対するノイズ遮蔽部材４０の溶着とを、同時に行うことができる。 The noise shielding member 40 has a form in which a magnetic material layer 41 and a welding layer 42 for fixing the magnetic material layer 41 to the sheet material 10 are laminated. The welding layer 42 is made of the same material as the sheath 27 that constitutes the outermost layer of the first transmission line 20. According to this configuration, welding of the first transmission line 20 to the sheet material 10 and welding of the noise shielding member 40 to the sheet material 10 can be performed at the same time.
