[考案の技術分野]
本考案は、応急ケーブル等のように外部遮蔽層
として銅線編組を有する電力ケーブルの接地構造
に関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a grounding structure for a power cable having a copper wire braid as an external shielding layer, such as an emergency cable.
[考案の技術的背景]
応急ケーブルは延線およびケーブルドラムへの
巻取り等が比較的頻繁に行なわれることから曲げ
回数が多く、このため通常のケーブルより可撓性
を要求される。[Technical background of the invention] Emergency cables are stretched and wound around cable drums relatively frequently, so they are bent many times and are therefore required to be more flexible than ordinary cables.
従つて、一般に応急ケーブルの導体の素線径は
通常のケーブルより細くされ、またその外部遮蔽
層は銅テープに代つて銅線編組により構成されて
いる。 Therefore, the diameter of the conductor of an emergency cable is generally smaller than that of a normal cable, and its outer shielding layer is made of a copper wire braid instead of a copper tape.
しかして、外部遮蔽層を有するケーブルは遮蔽
層を接地する必要があり、従来は第1図に示す接
地構造がとられている。 Therefore, in a cable having an external shielding layer, it is necessary to ground the shielding layer, and conventionally, a grounding structure shown in FIG. 1 has been used.

銅線編組3との間に湿気が侵入するのを防止する
ための保護テープ巻き層である。 That is, in the same figure, the outer semiconducting layer 2 on the cable insulator 1 at the cable terminal part, the copper wire braid 3 serving as the outer shielding layer, the cable sheath 4, etc. are successively stripped off, and the end of the copper wire braid 3 is removed. The copper wire 5 wound around it is folded back, further tied up with the copper wire 6, and the copper wire 6 is directly attached to the cable sheath 4.
Either the copper wire 7 is extended upward and used as a grounding wire, or the copper wire 7 is separately wound on the copper wire braid 3 and used as a grounding wire. In addition, the reference numeral 8 in the figure is a protective tape wrapping layer for preventing moisture from entering between the cable sheath 4 and the copper wire braid 3.
[背景技術の間隔点]
しかしながら、上記従来の接地構造において
は、接地線とする銅線6あるいは7を銅線編組3
と確実に接触させるため、両者を適当に半田付け
するが、この半田付けの際使用するフラツクスが
毛細管現象により銅線編組3の素線間に流入す
る。しかしてこのフラツクスを入念に除去しない
と銅線6または7は腐食し、特に素線径の小さい
銅線編組では断線して外部遮蔽層の接地が不完全
となるおそれがあつた。[Background Art Interval Points] However, in the above-mentioned conventional grounding structure, the copper wire 6 or 7 serving as the grounding wire is connected to the copper wire braid 3.
In order to make sure that they are in contact with each other, they are properly soldered, but the flux used during this soldering flows between the strands of the copper wire braid 3 due to capillary action. However, unless the lever flux is carefully removed, the copper wires 6 or 7 will corrode, and especially in the case of a copper wire braid with a small wire diameter, there is a risk that the wire will break, resulting in incomplete grounding of the external shielding layer.
[考案の目的]
本考案は上記の事情に基づいてなされたもの
で、銅線編組の腐食を引き起こす半田付けを行な
わずに構成され、銅線編組の断線のおそれのない

する。[Purpose of the invention] The present invention was developed based on the above circumstances, and is intended to provide a grounding structure for power cables that does not require soldering, which causes corrosion of the copper wire braid, and is free from the risk of disconnection of the copper wire braid. The purpose is to provide.

により緊縛してある。 In FIG. 2, the copper wire braid 3, cable sheath 4, etc. are sequentially stripped off from the outer semiconducting layer at the cable terminal, and the end of the copper wire braid 3 is folded back from the copper wire 5 wound around it. This is the same as in the case of FIG. In this embodiment, the ends of the copper wire braid 3 are unwound, folded back and bundled into one bundle, which is crimped and fastened to a crimp terminal 10 at one end of the ground metal body 9. etc. binding line 11
He is tied up.
しかして、圧着端子10は接地金属体9の一端

線3aを真直ぐに矯正する。 In Fig. 3, first, the copper wire 5 is wound around a predetermined position to tighten the outer periphery of the copper wire braid 3, and then the braid at the end of the copper wire braid on the left side of the figure is unbraided from the copper wire 5, and each strand is Straighten 3a.
次に第4図に示すように、各素線3aをケーブ
ルシース4側に折返し、銅線5の近傍の周上をバ
インド線11で緊縛する。 Next, as shown in FIG. 4, each strand 3a is folded back toward the cable sheath 4 side, and the circumference near the copper wire 5 is tied tightly with a bind wire 11.
