ルに係るものである。[Detailed Description of the Invention] (Industrial field of application) The present invention is formed by branching and connecting a trunk line weak electric cable such as a trunk communication line to another branching weak cable such as a communication line. It relates to a weak electric branch cable.
（従来の技術） 従来、この種の弱電分岐ケーブルは実在していなかっ

なかったためである。したがって、弱電ケーブルの分岐
は現場で、手作業で行われていた。(Prior Art) Conventionally, this type of weak-electric branch cable has not actually existed. This is because the conductor is as thin as 0.4 to 1.2 mm,
This is because the insulator such as polyethylene or foamed polyethylene has an extremely thin thickness of 0.13 to 0.5 mm and cannot withstand the high temperature of 150 to 200 ° C. received during molding. Therefore, the branch of the light electric cable was manually performed in the field.
（考案が解決しようとする問題点） 現場手作業においては、次のような問題点があった。(Problems to be solved by the invention) The following problems were encountered in the manual work on site.
（１）作業に時間がかかった。(1) It took time to work.
（２）ナイフなどを使用する手作業では、細い導体を傷
つけることが多かった。(2) In manual work using a knife or the like, a thin conductor is often damaged.
（３）シースが剥ぎ取られた分岐部は、普通プラスチッ
ク粘着テープを巻回して保護していたので、作業が面倒
で、しかも十分な防湿性能が得られなかった。(3) Since the branch portion from which the sheath was peeled off was usually protected by winding a plastic adhesive tape, the work was troublesome and sufficient moistureproof performance could not be obtained.
（４）また、分岐が高価なジョイントボックス中で行わ
れる場合があり、不経済であった。(4) In addition, branching may be performed in an expensive joint box, which is uneconomical.
この考案はこれらの問題点を全て解決するためになされ
たものである。This invention was made to solve all of these problems.
（問題点を解決するための手段） この考案の実施の一例を示す図面について説明する。幹

などの方法により、適宜に絶縁処理２を施し、絶縁接続
部３を形成するのである。(Means for Solving Problems) A drawing showing an example of implementation of the present invention will be described. For example, after winding a predetermined conductor of the low-voltage cable 7 that is branched and connected to a predetermined conductor of the low-voltage cable 6 serving as a trunk line, and then soldering that portion to form the conductor connection portion 1,
The insulating connection 2 is appropriately applied by a method such as winding an adhesive insulating tape around the conductor connecting portion 1 to form the insulating connecting portion 3.
次に、絶縁接続部３を所定の形状に集合し、その上に、

モールド成形するのである。Next, the insulated connection parts 3 are assembled into a predetermined shape, and then,
Insulation material 4 such as paper tape, non-woven fabric, etc., collectively covering the sheath stripping portions of the main line weak electric cable 6 and the branch weak electric cable 7
Then, the protective layer 5 made of vinyl or the like is molded on the surface.
断熱材４の使用は、保護層５のモールド時の高温を遮断
し、内部への伝導を阻止し、弱電ケーブルの薄く、熱に
弱い絶縁体を高温から保護するためのもので、この考案
の実施には不可欠な技術的事項である。The use of the heat insulating material 4 is to shield high temperature when the protective layer 5 is molded, to prevent conduction to the inside, and to protect the thin, heat-insulating insulator of the light electric cable from high temperature. It is an essential technical matter for implementation.

ルを実現し得るのである。(Function) Since the branching process is carried out in a specialized factory where quality control is thoroughly performed, it is possible to prevent the conductor from being damaged by a knife or the like which is a problem in the field work. The heat insulating material applied between the sheath stripping parts of the main line weak electrical cable and the branch weak electrical cable at once protects the insulator from high temperature during molding, and the mold protective layer integrated with the sheath of the weak electrical cable is externally applied. To prevent ingress of moisture. The presence of a collective heat insulating material layer immediately below the mold protective layer makes it possible to realize a mold type weak electrical branch cable.
（考案の効果） この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。(Effect of the Invention) Since the present invention is configured as described above, it has the following effects.
（１）モールドタイプの弱電分岐ケーブルを実現でき

（２）導体損傷のおそれがない。(2) There is no risk of conductor damage.
（３）防湿が完全に行われる。(3) Moisture proof is completely performed.
（４）高価なジョイントボックスを必要としない。(4) No expensive joint box is required.
（５）現場作業がないので、工期が短縮できる。(5) Since there is no on-site work, the construction period can be shortened.
