【考案の詳細な説明】
本考案は波付金属鎧装を有するケーブル（以下単にコル
ゲートケーブルと称する）の分岐接続部の構造に関する
ものである。[Detailed Description of the Invention] The present invention relates to a structure of a branch connection portion of a cable having a corrugated metal armor (hereinafter simply referred to as a corrugated cable).
従来この種の分岐接続部は、スリーブで導体相互を接続
し、その上に絶縁テープを巻き付け、更にその上に鋼管
もしくはビニル製管等を遊挿し、中空部に不飽和ポリエ

させていた。Conventionally, this type of branch connection connects the conductors with each other with a sleeve, wraps an insulating tape over the sleeve, loosely inserts a steel pipe or vinyl pipe, etc., and fills the hollow part with unsaturated polyester, epoxy resin, etc. The compound was injected and cured.
しかし、これらの作業は全て現場で実施されていたので
、作業に画一性がなく、高い信頼性も望めなかった。However, since all of this work was carried out on-site, there was no uniformity in the work, and high reliability could not be expected.
本考案はこれらの欠点を除去するためになされたもので
、分岐接続部を簡単かつ画一的に成形すると共に、水密
性にも優れた鋼コルゲートケーブルの分岐接続部の構造
の提供を目的とするものである。The present invention was made to eliminate these drawbacks, and aims to provide a structure for branch connections of steel corrugated cables that can be easily and uniformly formed and has excellent watertightness. It is something to do.
次で、本考案をその一実施例を示す図面に基づいて詳細
に説明すると、
１は銅、アルミ導体２等から威るコルゲートケーブルで
あり、このケーブル１の絶縁体３、鋼コルゲート４、外

。Next, the present invention will be explained in detail based on a drawing showing one embodiment of the invention. 1 is a corrugated cable made of copper, aluminum conductor 2, etc., and the cable 1 has an insulator 3, a steel corrugated material 4, and an external The sheath 5 is sequentially peeled off to expose the conductor 2.
６は銅、アルミ導体２′等から威る波付金属鎧装を有す
る分岐線（以下、単に分岐線と呼称する）であり、この
分岐線６の絶縁体３′、鋼コルゲート４′外部シース５
′も順次段剥ぎして導体２′を露出し、この導体２′と
コルゲートケーブル１の露出した導体２とをスリーブ７
により相互を接続しである。6 is a branch line (hereinafter simply referred to as a branch line) having a corrugated metal armor made of copper, aluminum conductor 2', etc.; 5
' is sequentially stripped off to expose the conductor 2', and the conductor 2' and the exposed conductor 2 of the corrugated cable 1 are connected to the sleeve 7.
They are connected to each other.
８は自己融着テープ等の絶縁テープである。8 is an insulating tape such as a self-fusing tape.
９はコルゲートケーブル１ど分岐線６との分岐接続部を
保護するためにかぶせる分割した波付鋼管（以下、単に
分割鋼コルゲート管と呼称する）であり、その両端部の
みが平滑に仕上げられている。9 is a divided corrugated steel pipe (hereinafter simply referred to as a divided steel corrugated pipe) that is covered to protect the branch connection between the corrugated cable 1 and the branch line 6, and only both ends thereof are finished smooth. There is.
そして、この分割鋼コルゲート管９の平滑部を夫々のケ
ーブル１および分岐線６の波付金属鎧装端部に重ね、そ
の上を銅細線等の細線１０で縛り、分割鋼コルゲート管
９を分岐部に固定する。Then, the smooth portions of the split steel corrugated pipes 9 are overlapped with the corrugated metal armored ends of the respective cables 1 and branch lines 6, and the tops thereof are tied with thin wires 10 such as thin copper wires, and the split steel corrugated pipes 9 are branched. to be fixed in place.
なお、ケーブル１および分岐線６のサイズに合うように
平滑部の寸法を調整するために実施例に示したような切
り込みを平滑部に設けることば自由である。Incidentally, in order to adjust the dimensions of the smooth part to match the sizes of the cable 1 and the branch line 6, it is possible to provide a cut in the smooth part as shown in the embodiment.
１１は塩化ビニル樹脂等から成る保護層でありこの保護
層１１は分割鋼コルゲート管９上および夫々のケーブル
１および分岐線６の外部シース５．５′とかかり、それ
らと一体になるように射出成形機でモールド成形されて
いる。Reference numeral 11 denotes a protective layer made of vinyl chloride resin, etc., and this protective layer 11 is applied to the split steel corrugated pipe 9 and the outer sheaths 5.5' of the respective cables 1 and branch lines 6, and is injected so as to be integrated therewith. Molded using a molding machine.
本考案は以上のように構成されているので、次のような
効果を有している。Since the present invention is configured as described above, it has the following effects.
（１）分割鋼コルゲート管を使用しているので、着脱の
作業が容易である。(1) Since split steel corrugated pipes are used, attachment and detachment work is easy.
（２）このコルゲート管の両端は平滑状に仕上げられて
いるので、この部分に適宜の切込みを入れることにより
、適用サイズ範囲を拡大することができる。(2) Since both ends of this corrugated pipe are finished in a smooth shape, the applicable size range can be expanded by making appropriate cuts in these parts.
（３）従来の直管に比し、波付管であるので、分岐接続
部の可撓性が良好になる。(3) Since the pipe is a corrugated pipe, the flexibility of the branch connection is better than that of a conventional straight pipe.
（４） 保護層はモールド成形で水密性に仕上げられ
ているので、分岐接続部の性能は向上する。(4) Since the protective layer is molded to be watertight, the performance of the branch connection is improved.
（５）全般的に作業が画一的に行える。(5) Work can be performed uniformly overall.
特に設備のそろった工場で分岐作業を行えるので従来の
現場作業に比し、分岐接続部の信頼性は著しく向上する
。In particular, branching work can be performed at a factory with all the necessary equipment, so the reliability of branch connections is significantly improved compared to conventional on-site work.
（６） 従って、寿命が引延され、経済的である。(6) Therefore, the life is extended and it is economical.
以上のような効果を有し、本考案の工業的利用価値は顕
著である。With the above-mentioned effects, the present invention has remarkable industrial utility value.
