した共通のダム部３を構成する。 To explain this kind of cable branch connection with reference to Fig. 1, the connection cables consisting of the main cable C 1 and the branch cable C 2 are lined up, the sheath and shield of the core connection part are removed, and the sheath end remaining on the connection cable is removed. A brushing part 1 of a certain width is provided on the (connection side), and after thoroughly wiping the part clean and making it clean, wrap it with protective tape (not shown) to temporarily prevent it from being affected by dust, oil, grease, etc. and then clip the cable core 2 (not shown).
A common dam part 3 covering the main cable C 1 and the branch cable C 2 is formed at the sheath end on the cable connection side.

は前述のダム部３を形成するに際し、第２図に示
すようにシーリングテープ４を主ケーブルC1及
び分岐ケーブルC2の周囲に巻くとともに両ケー
ブルの間にもシーリングテープを介在させてダム
部３を構成していたので両ケーブルの間に微少な
空隙が発生するばかりでなく、その表面層も凹凸
が激しいためにプラスチツクフイルム４の端部の
取付け部分にも隙間が生じ、これらの隙間から、
防水混和物が外部に流出し、接続部の防水性を損
うおそれがあつた。 A plastic film 5 is fixed at both ends of the dam part 3 and wrapped around the core wire connection part, and a petroleum resin, polybutene microcrystalline wax is applied from the seam of the plastic film 5, etc. A jelly-like moisture-proofing mixture 6 such as the above is injected, and the moisture-proofing mixture 6 is injected from the outside of the plastic film 5 so that the moisture-proofing mixture 6 is permeated between the core wire connections of the cable to make it completely moisture-proof. At the same time, remove the protective tape on the brushing part 1, wrap a sealing tape or the like on the cable connection part if necessary, and apply a heat-shrinkable covering material such as a heat-shrinkable polyethylene sheet 7 to the outside to cover the entire cable connection part. The connection is completed by heat shrinking. However, conventionally, when forming the aforementioned dam part 3, a sealing tape 4 was wrapped around the main cable C1 and the branch cable C2 , and a sealing tape was also interposed between both cables, as shown in FIG. Since the dam part 3 was formed, not only a small gap was created between both cables, but also the surface layer was very uneven, so a gap was also created at the end of the plastic film 4 where it was attached. From the gap,
There was a risk that the waterproofing mixture would leak outside and impair the waterproofness of the connection.
これに対し本発明は、前述のダム部３を形成す
るに際し、第３図に示すように、主ケーブルC1
と分岐ケーブルC2の心線接続側のシース端部に、
エチレン酢ビ共重合体、エチレンアクリル酸エス
テル共重合体の如き粘着剤で、両ケーブルを共通
被覆するようにして両ケーブル間に隙間を生ずる
ことなく、かつ表面平滑に仕上げ、断面ほゞ長円
形のダム部３を形成するものである。 On the other hand, in the present invention, when forming the above-mentioned dam part 3, as shown in FIG.
and the sheath end on the core connection side of branch cable C 2 ,
Both cables are commonly coated with an adhesive such as ethylene vinyl acetate copolymer or ethylene acrylic acid ester copolymer, so that there are no gaps between the two cables, and the surface is smooth and the cross section is approximately oval. The dam part 3 is formed.
従つて本発明によるダム部３は外側に心線接続
部を包被するプラスチツクフイルム５の端部を固
定する際に密着して隙間を生じないほか、接続部
全体を包被する熱収縮性スリーブ７の如き保護部
材とも密着して構成され易く、内部の気密性を高
度に保つことができるので、優れたケーブル分岐
接続部を極めて容易に提供することができる。 Therefore, the dam part 3 according to the present invention not only fits tightly without creating a gap when fixing the end of the plastic film 5 that covers the core wire connection part to the outside, but also has a heat-shrinkable sleeve that covers the entire connection part. It is easy to be constructed in close contact with a protective member such as 7, and a high degree of internal airtightness can be maintained, so that an excellent cable branch connection part can be provided extremely easily.
