Generally, in lead-free junction boxes such as OF cables, as shown in Figure 3, the junction box copper pipe 1 and OF
An aluminum sheath 2 of the cable is electrically connected with a bond wire 3. Therefore, in a cable junction box with such a configuration, when a ground fault occurs in a cable part such as an OF cable, a ground fault current is transmitted to the bond wire 3 connected to the aluminum sheath 2, the junction box copper tube 1, and the like. It will flow to the ground via the provided grounding wire 4.

That is, the cable connection part according to the present invention is a cable connection part formed by electrically connecting a connection box that covers a conductor connection part of a cable having a corrugated metal sheath and the corrugated metal sheath with a bond wire,
A valley filling member is provided in the valley portion of the corrugated metal sheath with one end of the bond wire attached to the outer surface, and one end of the bond wire is secured by a tightening fitting provided on the outer periphery of the valley filling member. It is characterized in that it is fastened and fixed onto the corrugated metal sheath.
以下、本考案を一実施例の図面に基づいて説明

Hereinafter, the present invention will be explained based on the drawings of one embodiment. In FIG. 1, one end of a bond wire 6 made of a tinned annealed copper wire or the like is attached to the outer surface of a corrugated metal sheath 5 such as an aluminum sheath. A valley filling member 7 made of a flexible member such as a plain knitted copper wire is wound around the outer periphery of the corrugated metal sheath 5 to which one end of the bond wire 6 is attached.
８は、谷埋部材７の外周に配設された２つ割構
成の緊締金具で、この緊締金具の締付けによつて
ボンド線６が波付金属シース６の外表面に密接さ
れる。 Reference numeral 8 denotes a two-piece fastening fitting disposed on the outer periphery of the valley filling member 7. By tightening this fastening fitting, the bond wire 6 is brought into close contact with the outer surface of the corrugated metal sheath 6.
第２図は、谷埋部材７の外周に少なくとも２個

各緊締金具の締付けによつてボンド線６を波付金
属シース５の外表面に密接させた場合の他の実施
例を示している。 FIG. 2 shows that at least two fastening fittings 8a, 8b, 8c are arranged in the axial direction on the outer periphery of the valley filling member 7,
Another embodiment is shown in which the bond wire 6 is brought into close contact with the outer surface of the corrugated metal sheath 5 by tightening the respective fasteners.
この実施例においては、緊締金具が分割されて
いるので、波付金属シース５への締付力に偏りが
なくなり、安定した電気的接続ができる利点があ
る。 In this embodiment, since the tightening fittings are divided, there is an advantage that the tightening force applied to the corrugated metal sheath 5 is not biased and a stable electrical connection can be made.
なお、前述の実施例においては、谷埋部材とし
て平編銅線を使用した場合について述べてあるが
本考案はこれに限定されず、例えば、ゴム状弾性
体を使用してもよい。 In addition, in the above-mentioned embodiment, the case where a plain knitted copper wire is used as the valley filling member is described, but the present invention is not limited to this, and for example, a rubber-like elastic body may be used.
図中９は、緊締金具のフランジ１０に設けられ
た透孔、１１はボンド線の他端に取付けられた端
子を示している。 In the figure, reference numeral 9 indicates a through hole provided in the flange 10 of the fastening fitting, and reference numeral 11 indicates a terminal attached to the other end of the bond wire.
