Description
【０００１】[0001]
本考案は同軸ケーブルに関する。更に詳しくは、広範な電子機器の内部配線に 使用され、特に特定の形状にフォーミング（形成）して使用されるのに好適な形 状保持性を有する同軸ケーブルに関するものである。 The present invention relates to a coaxial cable. More specifically, the present invention relates to a coaxial cable having a shape-retaining property, which is suitable for use in a wide variety of internal wirings of electronic devices and is particularly suitable for forming (forming) into a specific shape.
【０００２】[0002]
これまで予め特定の形状にフォーミングして使用できるという同軸ケーブル、 いわゆる形状保持性を有する同軸ケーブル（以下、形状保持性同軸ケーブルと略 記する）としては、セミリジッド同軸ケーブルやセミフレキシブル同軸ケーブル がよく知られている。セミリジッド同軸ケーブルの製造は通常、中心導体の外周 に絶縁層を設けた絶縁線心を銅パイプに挿入してから、当該絶縁外径までダイを 使用して引き落として製造している。また、セミフレキシブル同軸ケーブルの製 造は通常、中心導体の外周に絶縁層を設けた絶縁線心の外周に金属細線を編組し てシールド層を設け、続いて編組シールド層をはんだ等で浸漬めっきして外部導 体を形成している。 Conventionally, as a coaxial cable that can be used after being formed into a specific shape in advance, a so-called shape-retaining coaxial cable (hereinafter abbreviated as shape-retaining coaxial cable), a semi-rigid coaxial cable or a semi-flexible coaxial cable is often used. Are known. The manufacturing of semi-rigid coaxial cables is usually done by inserting an insulated wire core with an insulating layer around the outer periphery of the center conductor into a copper pipe and then pulling it down to the insulating outer diameter using a die. In addition, the manufacturing of semi-flexible coaxial cables is usually performed by braiding a thin metal wire on the outer circumference of the insulating core with an insulating layer on the outer circumference of the center conductor to form a shield layer, and then by dipping plating the braided shield layer with solder or the like. To form an external conductor.
【０００３】 これらの形状保持性同軸ケーブルは、両端の外部導体および絶縁層を剥ぎ加工 をし、また、同軸コネクタを接続して製品となるが、実装し易くするために予め 特定の２次元あるいは３次元の形状にフォーミングすることが多い。これら形状 保持性同軸ケーブルの外部導体は硬くて剛直性を有するために、その形状がその まま保持されるものであり、このことがこれらの同軸ケーブルの一つの特徴とな っている。These shape-retaining coaxial cables are manufactured by stripping the outer conductors and insulating layers at both ends and connecting coaxial connectors to form a product. Often formed into a three-dimensional shape. Since the outer conductors of these shape-retaining coaxial cables are hard and rigid, their shape is maintained as they are, which is one of the characteristics of these coaxial cables.
【０００４】[0004]
前記形状保持性同軸ケーブルに於いて、セミリジッド同軸ケーブルにあっては 、長尺化や細径化が困難である等の欠点があり、また、ダイによる引き落としが 必要であった。一方、セミフレキシブル同軸ケーブルにあっては、浸漬めっき工 程が必須であるために、やはり長尺化や細径化が困難である等の欠点があり、ま た、専用の製造装置が必要であるために製造上の弾力性が劣っており、製品価格 を低減する上での制約となっていた。 Among the shape-retaining coaxial cables, the semi-rigid coaxial cable has drawbacks such as difficulty in lengthening and thinning, and it is necessary to drop it by a die. On the other hand, semi-flexible coaxial cables have drawbacks such as difficulty in lengthening and diameter reduction, because the immersion plating process is indispensable, and dedicated manufacturing equipment is required. Therefore, the elasticity in manufacturing was inferior, and it was a constraint in reducing the product price.
【０００５】 本考案は上記従来技術が有する各種問題点を解決するためになされたもので、 形状保持性に優れており、更に長尺化や細径化が容易でコストが安く製造できる 同軸ケーブルを提供することを目的とする。The present invention has been made in order to solve the various problems of the above-mentioned conventional technology, and is excellent in shape retention, and can be manufactured at a low cost with easy lengthening and diameter reduction. The purpose is to provide.

第１の観点では本考案は、内部導体１の外周に、順次絶縁層２および外部導体 ３を形成してなる同軸ケーブルであって、 前記外部導体３が第１の外部導体として複数本の金属細線の整列横巻きからな る金属細線横巻層３ａおよび第２の外部導体として金属テープを重なり部を設け て巻回した金属テープ巻回層３ｂの複合構造からなり、また前記金属細線の外径 が前記絶縁層２の外径の１／８以下であり、また前記金属テープの厚さが前記絶 縁層２の外径の１／２５〜１／７であり、更に前記金属テープの重なり部が当該 テープ幅の１／３〜３／４である形状保持性を有する同軸ケーブルにある。 A first aspect of the present invention is a coaxial cable in which an insulating layer 2 and an outer conductor 3 are sequentially formed on an outer periphery of an inner conductor 1, wherein the outer conductor 3 is a plurality of metal as a first outer conductor. It has a composite structure of a metal thin wire horizontal winding layer 3a consisting of aligned horizontal windings of thin wires and a metal tape winding layer 3b wound with an overlapping portion of a metal tape as a second outer conductor.

【０００７】 第２の観点では本考案は、前記第１の観点の形状保持性を有する同軸ケーブル の外周に、更にジャケット４が設けられている形状保持性を有する同軸ケーブル にある。In a second aspect, the present invention resides in a shape-retaining coaxial cable in which a jacket 4 is further provided on the outer periphery of the shape-retaining coaxial cable of the first aspect.
【０００８】 第３の観点では本考案は、内部導体１の外周に、順次絶縁層２、外部導体３お よびジャケット４を形成してなる同軸ケーブルであって、 前記外部導体３が第１の外部導体として金属テープを重なり部を設けて巻回し た金属テープ巻回層３ｂおよび第２の外部導体として複数本の金属細線の整列横 巻きからなる金属細線横巻層３ａの複合構造からなり、また前記金属細線の外径 が前記絶縁層２の外径の１／８以下であり、また前記金属テープの厚さが前記絶 縁層２の外径の１／２５〜１／７であり、更に前記金属テープの重なり部が当該 テープ幅の１／３〜３／４である形状保持性を有する同軸ケーブルにある。A third aspect of the present invention is a coaxial cable in which an insulating layer 2, an outer conductor 3 and a jacket 4 are sequentially formed on an outer circumference of an inner conductor 1, wherein the outer conductor 3 is a first cable. It has a composite structure of a metal tape winding layer 3b in which a metal tape is wound as an outer conductor with an overlapped portion and a metal thin wire horizontal winding layer 3a composed of aligned horizontal windings of a plurality of metal thin wires as a second outer conductor. Further, the outer diameter of the metal thin wire is 1/8 or less of the outer diameter of the insulating layer 2, and the thickness of the metal tape is 1 / 25-1 / 7 of the outer diameter of the insulating layer 2. Further, the overlapping portion of the metal tape is 1/3 to 3/4 of the tape width, and the coaxial cable has a shape-retaining property.
【０００９】 前記内部導体１としては、銅，銅合金線あるいはこれらの線に銀等の導電性金 属をめっきしためっき線が用いられる。 前記絶縁層２としては、各種のプラスチック樹脂の押出し層が用いられる。特 に低誘電率絶縁体，例えば四フッ化エチレン−六フッ化プロピレン共重合体樹脂 （ＦＥＰ樹脂）等が特性上好ましく用いられる。 前記金属細線としては、銅，銅合金細線あるいはこれらの細線に錫等の導電性 金属をめっきしためっき細線が用いられる。 前記金属テープとしては、銅あるいは銅合金テープが好ましく、また、これら テープに銀等の導電性金属がめっきされていてもよい。 前記ジャケットとしては、極薄のプラスチック樹脂，例えばポリ塩化ビニル（ ＰＶＣ）樹脂等の押出しや薄いプラスチックフィルム，例えばポリエステルフィ ルムの巻回によって形成される。As the inner conductor 1, a copper or copper alloy wire or a plated wire obtained by plating these wires with a conductive metal such as silver is used. As the insulating layer 2, extruded layers of various plastic resins are used. In particular, a low dielectric constant insulator, such as a tetrafluoroethylene-hexafluoropropylene copolymer resin (FEP resin), is preferably used because of its characteristics. As the metal thin wires, copper, copper alloy thin wires or plated thin wires obtained by plating these thin wires with a conductive metal such as tin are used. As the metal tape, a copper or copper alloy tape is preferable, and these tapes may be plated with a conductive metal such as silver. The jacket is formed by extruding an ultra-thin plastic resin such as polyvinyl chloride (PVC) resin or winding a thin plastic film such as a polyester film.
【００１０】 前記金属細線の外径を前記絶縁層２の外径の１／８以下に限定している理由は 、金属細線の外径が前記絶縁層２の外径の１／８を超えると、当該金属細線の剛 性によって形状保持性が低下するためである。The reason why the outer diameter of the thin metal wire is limited to ⅛ or less of the outer diameter of the insulating layer 2 is that the outer diameter of the thin metal wire exceeds ⅛ of the outer diameter of the insulating layer 2. This is because the shape retention is reduced due to the rigidity of the metal thin wire.
【００１１】 また、前記金属テープの厚さを前記絶縁層２の外径の１／２５〜１／７の範囲 に限定している理由は、１／２５より薄いものでは形状保持性に劣るためであり 、また、１／７を超えるものではケーブル製造が困難になると共にケーブルが剛 直になり過ぎるためである。Further, the reason why the thickness of the metal tape is limited to the range of 1 / 25-1 / 7 of the outer diameter of the insulating layer 2 is that if it is thinner than 1/25, the shape retention property is poor. On the other hand, if it exceeds 1/7, it becomes difficult to manufacture the cable and the cable becomes too rigid.
【００１２】 また、前記金属テープの重なり部を当該テープ幅の１／３〜３／４に限定して いる理由は、形状保持性とケーブル製造の容易さから選定したものである。 これらの限定条件は、順次金属細線横巻層３ａおよび金属テープ巻回層３ｂか らなる外部導体３構造の形状保持性同軸ケーブル、及び、順次金属テープ巻回層 ３ｂおよび金属細線横巻層３ａからなる外部導体３構造の形状保持性同軸ケーブ ルにおいて望ましい範囲である。Further, the reason why the overlapping portion of the metal tape is limited to 1/3 to 3/4 of the tape width is that it is selected from the viewpoint of shape retention and ease of cable production. These limiting conditions are a shape-retaining coaxial cable having an outer conductor 3 structure consisting of a metal thin wire horizontal winding layer 3a and a metal tape winding layer 3b, and a metal tape winding layer 3b and a metal thin wire horizontal winding layer 3a. This is a desirable range for the shape-retaining coaxial cable with the outer conductor 3 structure consisting of.
