Description

シールド電線Shielded wire
　本発明は、シールド電線に関する。 The present invention relates to a shielded electric wire.
　自動車内の電気配線において、ノイズの影響を受け易いあるいはノイズを発生し易い機器への配線には、信号の伝送等を行う電線の周囲にシールド層（電磁波遮蔽層）を備えたシールド電線が使用される。 In electrical wiring in automobiles, shielded wires with a shield layer (electromagnetic wave shielding layer) around the wires used for signal transmission are used for wiring to devices that are easily affected by noise or generate noise. Is done.
　特許文献１には、少なくとも１本の電線とドレイン線とからなる複数の電線と、これら複数の電線を覆う導電シートと、保護テープとで構成されるシールド電線が開示されている。導電シートは、電線に電磁波シールド性を付与するものである。導電シートは、長尺帯状とされており、電線に縦添えされた状態で当該電線に巻き付けられており、長手方向に沿った両側の辺縁部同士が上下に重ね合わせられている。また、保護テープは、長尺状のテープであり、導電シートの外周に螺旋状に巻き付けられている。 Patent Document 1 discloses a shielded electric wire including a plurality of electric wires including at least one electric wire and a drain wire, a conductive sheet covering the plurality of electric wires, and a protective tape. The conductive sheet imparts electromagnetic wave shielding properties to the electric wire. The conductive sheet has a long band shape and is wound around the electric wire in a state of being vertically attached to the electric wire, and the edge portions on both sides along the longitudinal direction are vertically overlapped. The protective tape is a long tape and is wound around the outer periphery of the conductive sheet in a spiral shape.

　例えばエンジンルーム等の環境にシールド電線が配索された場合、当該シールド電線は雨水に曝される可能性がある。従来のシールド電線では、保護テープの重ね合わせ箇所から内部へと水が進入した場合に、シールド部材を構成する金属層に腐食が起こり、シールド性能を低下させる可能性がある。このように、従来のシールド電線では防水対策が十分になされていないという問題があった。このため、エンジンルーム等のように水等を被る可能性がある環境では、シールド電線を使用することができないという不都合があった。 For example, when a shielded cable is routed in an environment such as an engine room, the shielded cable may be exposed to rainwater. In the conventional shielded electric wire, when water enters from the overlapped portion of the protective tape to the inside, corrosion may occur in the metal layer constituting the shield member, and the shield performance may be deteriorated. As described above, the conventional shielded electric wire has a problem that waterproofing measures are not sufficiently taken. For this reason, there existed a problem that a shielded electric wire could not be used in the environment which may receive water etc. like an engine room.

　以下、図面を参照して、本発明に係るシールド電線の好適な実施形態を詳細に説明する。
（第１の実施形態）
　図１は、本発明の第１実施形態に係るシールド電線１を示す斜視図である。本第１実施形態に係るシールド電線１は、複数（本実施形態では３本）の被覆電線２と、ドレイン線３と、金属箔材４と、シート状部材５と、保護テープ６とで構成されている。 Hereinafter, with reference to drawings, a suitable embodiment of a shielded electric wire concerning the present invention is described in detail.
(First embodiment)
FIG. 1 is a perspective view showing a shielded electric wire 1 according to the first embodiment of the present invention. The shielded electric wire 1 according to the first embodiment includes a plurality (three in this embodiment) of covered electric wires 2, drain wires 3, a metal foil material 4, a sheet-like member 5, and a protective tape 6. Has been.
　被覆電線２は、芯線（導体）の周囲を絶縁被覆で覆った電線であり、シールド層を有していない。本実施形態において、３本の被覆電線２は、所定の撚りピッチで撚り合わされており、一つの電線束に纏められている。 The coated electric wire 2 is an electric wire in which the periphery of the core wire (conductor) is covered with an insulating coating, and does not have a shield layer. In the present embodiment, the three covered electric wires 2 are twisted together at a predetermined twist pitch, and are bundled into one electric wire bundle.
　ドレイン線３は、被覆電線２の芯線と略同一断面積の裸電線（電線）であり、長さが被覆電線２と略同一に設定されている。ドレイン線３は、３本の被覆電線２に縦添えされている。すなわち、ドレイン線３は、電線の軸方向に沿って３本の被覆電線２と束ねられている。 The drain wire 3 is a bare wire (wire) having substantially the same cross-sectional area as the core wire of the covered wire 2, and the length is set to be substantially the same as that of the covered wire 2. The drain wire 3 is vertically attached to the three covered electric wires 2. That is, the drain wire 3 is bundled with the three covered electric wires 2 along the axial direction of the electric wires.
　各被覆電線２の端部及びドレイン線３の端部には、それぞれ接続端子（図示せず）が接続されている。ドレイン線３は、各被覆電線２の端部側に位置する機器等の接地部に接地接続される。 A connection terminal (not shown) is connected to each end of each covered electric wire 2 and each end of the drain wire 3. The drain wire 3 is grounded and connected to a grounding portion of equipment or the like located on the end side of each covered electric wire 2.
　金属箔材４は、３本の被覆電線２及びドレイン線３の周囲を覆うシールド層を形成するシールド部材である。例えば金属箔材４は絶縁材料であるポリエチレンフィルムの片面に金属箔層（例えばアルミニウム箔層）が設けられて構成されており、当該金属箔層はシールド層として機能する。金属箔材４は、金属箔層を内側に向けて、被覆電線２及びドレイン線３の外周に巻き付けられる。巻き付けられた金属箔材４は、金属箔層がドレイン線３に接触することにより、ドレイン線３に導通状態になる。また、３本の被覆電線２及びドレイン線３からなる電線束と、金属箔材４との間には、導電性接着剤（図示せず）が充填されており、金属箔層とドレイン線３との導通状態の安定性が高められている。 The metal foil material 4 is a shield member that forms a shield layer covering the periphery of the three covered electric wires 2 and the drain wires 3. For example, the metal foil material 4 is configured by providing a metal foil layer (for example, an aluminum foil layer) on one side of a polyethylene film that is an insulating material, and the metal foil layer functions as a shield layer. The metal foil material 4 is wound around the outer periphery of the covered electric wire 2 and the drain wire 3 with the metal foil layer facing inward. The wound metal foil material 4 becomes conductive to the drain wire 3 when the metal foil layer contacts the drain wire 3. Further, a conductive adhesive (not shown) is filled between the wire bundle composed of the three covered electric wires 2 and the drain wires 3 and the metal foil material 4, and the metal foil layer and the drain wires 3 are filled. The stability of the conduction state is improved.
　シート状部材５は、金属箔材４の周囲を覆うものであり、防水性の観点から設けられている。シート状部材５は、３本の被覆電線２及びドレイン線３を周回できる程度の幅（電線の軸方向と直交する方向の長さ）を備えて電線の軸方向に長手となる長尺帯状に構成されており、金属箔材４に縦添えされた状態で当該金属箔材４の周囲に巻き付けられている。また、このシート状部材５は、電線の軸方向に延在する一対の辺縁部５ａが内面同士で接合されている。本第１実施形態では、シート状部材５の両側に位置付けられる一対の辺縁部５ａは同一幅に設定されており、それぞれの辺同士が揃った状態で接合されている。 The sheet-like member 5 covers the periphery of the metal foil material 4 and is provided from the viewpoint of waterproofness. The sheet-like member 5 has a width (a length in a direction perpendicular to the axial direction of the electric wire) that can circulate the three covered electric wires 2 and the drain wire 3 and has a long band shape that is long in the axial direction of the electric wire. The metal foil material 4 is wound around the metal foil material 4 while being vertically attached to the metal foil material 4. In addition, the sheet-like member 5 has a pair of side edge portions 5a extending in the axial direction of the electric wire joined together at the inner surfaces. In this 1st Embodiment, a pair of edge part 5a located in the both sides of the sheet-like member 5 is set to the same width, and it joins in the state in which each edge | side aligned.
　シート状部材５は、水が浸透しづらい材質であることが好ましく、また、シート状部材５同士の接着や金属箔材４との気密性を確保できることが好ましい。このようなシート状部材５としては、例えばそのシート素材としてシリコン等の樹脂を挙げることができ、当該シート素材の内面に粘着層が形成された粘着テープ又は粘着シートなどを用いることができる。すなわち、本第１実施形態では、両側の辺縁部５ａは接着にて内面同士が接合されることとなる。 The sheet-like member 5 is preferably made of a material that is difficult for water to permeate, and it is preferable that adhesion between the sheet-like members 5 and airtightness with the metal foil material 4 can be secured. Examples of such a sheet-like member 5 include a resin such as silicon as the sheet material, and an adhesive tape or an adhesive sheet in which an adhesive layer is formed on the inner surface of the sheet material can be used.
