される。Therefore, the terminal provisional treatment method for the OF cable according to the present invention prevents air from entering the OF cable 1 and leaks the insulating oil when the OF cable 1 is connected or removed. In order to prevent this, a method of sealing the cut end of the OF cable 1 with a terminal sealing cap A, for example, as shown in FIG. 3, at a low place of the OF cable 1 laid on a sloping ground, Used when cutting.
【００２０】即ち、本発明を実施するには、先ず、図４

As shown in, the metal sheath at the low position of the OF cable 1
Expose 16 over a specified length.

【００２２】なお、ベース鉛工を行う前に、金属製シー
ス16の表面を金属ブラシ等にて研磨しておく。Before performing the base lead work, the surface of the metal sheath 16 is polished with a metal brush or the like.
【００２３】次に、ベース鉛工層18から軸心方向に所定
寸法Ｌ1 離れた位置に於てＯＦケーブル１を切断する。Next, the OF cable 1 is cut at a position separated from the base lead layer 18 by a predetermined dimension L 1 in the axial direction.

The mounting cylinder 2 having a length dimension L 2 smaller than
The metal sheath 16 of the F cable is externally fitted, and the inner end edge of the mounting cylinder 2 is located on the outer peripheral surface of the base lead layer 18.
【００２５】なお、実際には、所定寸法Ｌ1 は取付用筒

As a result, if the inner end edge of the mounting cylinder 2 is located on the outer peripheral surface of the base lead layer 18 as described above, the outer end surface of the mounting cylinder 2 will be in the axial direction from the cut surface of the OF cable 1. It is located at a position that is inwardly of dimension L 3 .

高低差Ｈ（図３と図４参照）に基づく油圧により、水平

めて大となる。The insulating oil 20 leaks from the cut surface of the OF cable 1, and its flow rate is laid horizontally by the hydraulic pressure based on the height difference H (see FIGS. 3 and 4) of the inclined OF cable 1. This is extremely large as compared with the case where the OF cable 1 is cut.
【００２７】なお、作業中にＯＦケーブル１内に空気が

流しつつ行われる。In order to prevent air from entering the OF cable 1 during the work, an oil tank (not shown) for continuously replenishing the insulating oil 20 is connected to the terminal on the high side of the OF cable 1. . That is, the present invention is carried out while flowing the insulating oil 20 into the OF cable 1.
【００２８】次に、その状態───即ち取付用筒体２の

Then, as shown in FIG. 7, the inner edge of the mounting cylinder 2 is fixed to the base lead layer 18 by the main lead process. Reference numeral 21 is a main lead layer formed by main lead processing.
【００２９】しかして、この本鉛工の最中は、ＯＦケー
ブル１の切断面から絶縁油20が漏出するが、取付用筒体
２の外端面がＯＦケーブル１の切断面よりも軸心方向内

保持すれば、絶縁油20が取付用筒体２の外端側の開口部
内に流入する虞れはなくなる。During this lead process, however, the insulating oil 20 leaks from the cut surface of the OF cable 1, but the outer end surface of the mounting cylinder 2 is axially farther than the cut surface of the OF cable 1. Since it is located inside, if the cut end of the OF cable 1 is kept substantially horizontal, there is no risk that the insulating oil 20 will flow into the opening on the outer end side of the mounting cylinder 2.
【００３０】従って、本鉛工を施す部位から絶縁油20が
漏出することはなく、本鉛工を容易かつ迅速に行うこと
ができるといる利点がある。Therefore, there is an advantage that the insulating oil 20 does not leak from the portion to be subjected to the main lead work, and the main lead work can be performed easily and quickly.
【００３１】さらに、本鉛工を施す部位とＯＦケーブル
１の切断面との間には、バーナーの火炎が絶縁油20に届
かない程度の十分な距離があるため、火災の発生をも防
止できる。Further, since there is a sufficient distance between the portion to be subjected to the present lead work and the cut surface of the OF cable 1 so that the flame of the burner does not reach the insulating oil 20, it is possible to prevent the occurrence of fire. .
【００３２】そして、これらの利点は、絶縁油20の漏出
量がきわめて大なる場合でも変わることはなく、（図３

適となる。These advantages do not change even when the leakage amount of the insulating oil 20 is extremely large (see FIG. 3).
(As shown in FIG. 4) It is most suitable for the OF cable 1 laid on a sloping ground.

４と取付用筒体２の内部に絶縁油20が溜まる。After that, as shown in FIG. 8, the cap body 4 is externally fitted from the cut end side of the OF cable 1 and the opening end face of the cap body 4 is brought into close contact with the outer end face of the mounting cylinder 2 to secure the bolt. Cap body 4 with 5 and nut 6
Is fixed to the mounting cylinder 2. As a result, the insulating oil 20 collects inside the cap body 4 and the mounting cylinder 2.
【００３４】なお、図例では、キャップ本体４は長寸と
されているため、取付用筒体２の外端面とＯＦケーブル
１の切断面との間の寸法Ｌ3 を大きくとることができ
る。これにより、本鉛工の際に絶縁油20が燃える危険性
を一層低くすることができる。In the illustrated example, since the cap body 4 is elongated, the dimension L 3 between the outer end surface of the mounting cylinder 2 and the cut surface of the OF cable 1 can be increased. As a result, the risk of the insulating oil 20 burning during the lead process can be further reduced.
【００３５】次に、キャップ本体４の油吐出孔10から真
空引を行って、キャップ本体４と取付用筒体２の内部か

【００３６】真空引後は、図９に示す如く、キャップ本
体４の油吐出孔10を小蓋体12にて密閉する。After evacuation, as shown in FIG. 9, the oil discharge hole 10 of the cap body 4 is sealed with a small lid 12.

の端末仮処理方法。1. A base lead wire layer is formed along an outer peripheral surface of a metal sheath of the OF cable, and then the OF cable is placed at a position separated from the base lead wire layer by a predetermined dimension in the axial direction. After cutting, a mounting cylinder having a length smaller than the predetermined size is externally fitted to the metal sheath of the OF cable, and an inner end edge of the mounting cylinder is fixed to the base. It is positioned on the outer peripheral surface of the lead layer, and then the inner edge of the mounting cylinder is fixed to the base lead layer by the lead method in that state, and then from the cut end side of the OF cable. A cap main body having an opening on one side is externally fitted, and the opening end surface of the cap main body is closely attached to the outer end surface of the mounting cylinder, and the cap main body is fixed to the mounting cylinder to secure the OF cable. Seal the terminal with the cap body and the mounting cylinder. A terminal provisional treatment method for an OF cable, characterized in that
