Description
【考案の詳細な説明】 本考案は分岐付きケーブルの改良に関するものである。[Detailed explanation of the idea] The present invention relates to an improvement of a branched cable.
従来の分岐付きケーブルは、第１図に示すように幹線１
１から分岐コネクター１２を介して分岐線１３を分岐し
、該分岐部にモールド被覆１４を施したものであり、分
岐線１３の先端に灯具１５等を接続して使用する。Conventional cables with branches are connected to main line 1 as shown in Figure 1.
A branch line 13 is branched from the branch line 1 through a branch connector 12, and a mold coating 14 is applied to the branch part, and a lamp 15 or the like is connected to the tip of the branch line 13 for use.
この使用に際し、灯具収納器具１６等を接地する必要が
あるときは、接地幹線１７を布設し、該接地幹線１７か
ら接地線１８を分岐し、該分岐した接地線１８を器具１
６等に引込み接続している。When using this, if it is necessary to ground the lamp storage fixture 16, etc., a grounding main line 17 is laid, a grounding wire 18 is branched from the grounding main line 17, and the branched grounding wire 18 is connected to the fixture 1.
It is connected to 6th grade.
しかし上記のように、接地幹線１７から接地線１８を分
岐するのは非常に面倒であり、かつ器具１６内に分岐線
１３および接地線１８に引込むと、引込み個所が多くな
り引込み口の防水作業が煩雑になる等の問題があった。However, as mentioned above, branching the grounding wire 18 from the grounding main line 17 is very troublesome, and if the branching wire 13 and the grounding wire 18 are drawn into the appliance 16, there are many points to be drawn in, and waterproofing of the lead-in opening is required. There were problems such as the process becoming complicated.
本考案は上記問題に鑑みてなされたもので、その構成は
、幹線から分岐線を分岐し、分岐部をモールド被覆して
なる分岐付きケーブルにおいて、前記分岐線として多芯
ケーブルを使用し、該多芯ケーブルの一芯を接地するこ
とを特徴とするものである。The present invention has been made in view of the above problems, and has a structure in which a multi-core cable is used as the branch line, and a multi-core cable is used as the branch line, and the branch line is branched from the main line and the branch line is covered with a mold. This is characterized by grounding one core of the multicore cable.
本考案の一実施例を第２図を参照して詳細に説明するに
、１は幹線で例えば一芯のビニル絶縁ビニルシースケー
ブルが使用され、２は幹線１から分岐された分岐線で、
例えば三層のビニル絶縁ビニルシースケーブルが使用た
れる。An embodiment of the present invention will be described in detail with reference to FIG. 2. Reference numeral 1 denotes a main line, for example, a single-core vinyl insulated vinyl sheathed cable is used, and 2 indicates a branch line branched from the main line 1.
For example, a triple layer vinyl insulated vinyl sheathed cable is used.
分岐線２は短尺な一芯２１．２２と、長尺な一芯２３と
からなっており、短尺な一芯２１．２２の一端は分岐コ
ネクター４を介して幹線１に接続されており、また長尺
な一芯２３の一端は、前記分岐コネクター４を覆って設
けられたモールド被覆層５から外部に引出されて接地６
される。The branch line 2 consists of a short single core 21.22 and a long single core 23, and one end of the short single core 21.22 is connected to the main line 1 via the branch connector 4. One end of the long single core 23 is pulled out from the mold coating layer 5 provided to cover the branch connector 4 and connected to the ground 6.
be done.
なお短尺な一芯２１．２２の他端は灯具７に接続され、
長尺な一芯２３の他端は器具８に接続される。The other ends of the short single cores 21 and 22 are connected to the lamp 7,
The other end of the long single core 23 is connected to the instrument 8.
なお、上記実施例においては三層の分岐線を使用したが
、分岐線の芯線数はこれに限るものではなく一芯を接地
線として使用できる芯線数を有すればよい。In the above embodiment, a three-layer branch line is used, but the number of core wires in the branch line is not limited to this, as long as it has a number of core wires that allows one core to be used as a ground wire.
以上説明したように、本考案に係る分岐付きケーブルは
、分岐線として多芯ケーブルを使用し、該多芯ケーブル
の一芯を接地するようにしたものであるため、接地幹線
を必要とせず、しかも器具等の引込み口を一個所とする
ことができるため防水が極めて行ないやすくなる。As explained above, the branched cable according to the present invention uses a multicore cable as a branch line and one core of the multicore cable is grounded, so it does not require a grounding main line. Moreover, since there is only one outlet for appliances, etc., waterproofing becomes extremely easy.
また幹線に分岐線を接続しモールド被覆する作業は予め
工場で行なっておくことができるので、現場においては
、分岐線の一芯を灯具に接続し、かつ分岐線の一芯を器
具に接続すると共に一端を接地するだけでよいので工事
が著しく簡素化できる等の実用的効果がある。In addition, the work of connecting the branch line to the main line and covering it with mold can be done in advance at the factory, so at the site, one core of the branch line is connected to the light fixture, and one core of the branch line is connected to the fixture. In addition, since it is only necessary to ground one end, there are practical effects such as significantly simplifying the construction work.
