押えリング64の外径より大きく、中央にケーブル線心10
の通る孔72を有する。The plate-shaped pressing jig 70 has, for example, a disk shape, and has an outer diameter of
Larger than the outer diameter of the presser ring 64, and the cable core 10
Has a hole 72 passing therethrough.
この板状押し治具70は、孔72の直径を通る平面に沿っ
て二つ割りになつている。74は結合用のフランジであ
る。The plate-shaped pressing jig 70 is divided into two along a plane passing through the diameter of the hole 72. 74 is a connecting flange.
ケーブル導体12の接続を終え、エポキシユニツト16を
所定位置に設置したら（第５図）、それを架台54に固定
する。When the connection of the cable conductor 12 is completed and the epoxy unit 16 is set at a predetermined position (FIG. 5), it is fixed to the gantry 54.
また、プレモールド絶縁体20に押し金具60,バネ62,押
えリング64のアッセンブリを当て、その後面に板状押し
治具70を当てる。Further, the assembly of the press fitting 60, the spring 62, and the press ring 64 is applied to the pre-mold insulator 20, and the plate-shaped pressing jig 70 is applied to the rear surface thereof.
上記の引張り手段50を用い、架台54に反力をとりなが
ら、押し金具60などとともに、プレモールド絶縁体20を
移動させる。Using the above-described pulling means 50, the pre-mold insulator 20 is moved together with the press fitting 60 and the like while applying a reaction force to the gantry 54.
板状押し治具70は押えリング64よりも広い幅を有する
ので、押し金具60をプレモールド絶縁体20に当てておい
て、バネ62,押えリング64を介して、簡単な平板状の板
状押し治具70でありながら、プレモールド絶縁体20を傷
つけず移動させることができる。Since the plate-shaped pressing jig 70 has a wider width than the holding ring 64, the pressing metal member 60 is applied to the pre-mold insulator 20, and a simple flat plate-shaped member is passed through the spring 62 and the holding ring 64. Although the pressing jig 70 is used, the pre-mold insulator 20 can be moved without being damaged.
またプレモールド絶縁体20は、最終的にはエポキシユ
ニット16の中に相当深く押込まれる。Also, the pre-mold insulator 20 is ultimately pushed considerably deeper into the epoxy unit 16.
ところで、プレモールド絶縁体20の移動手段には、引
張り手段と押し手段の２種があり、押し手段には油圧や
ネジ等が用いられるが、引張り手段にはそれより簡単な
外線工事用の張線器等を用いることができる。By the way, there are two kinds of moving means of the pre-molded insulator 20, a pulling means and a pushing means, and a hydraulic means or a screw is used for the pushing means. A wire device or the like can be used.
プレモールド絶縁体20に直接板状押し治具70を当てて
引張る場合は、プレモールド絶縁体20の後端がエポキシ
ユニット16の端と一致するところまでが限度で、それよ

きるので、構造が簡単な引張り手段で、それより奥まで
プレモールド絶縁体20を送り込むことができる。When the plate-shaped pressing jig 70 is directly applied to the pre-mold insulator 20 and pulled, it is limited to a point where the rear end of the pre-mold insulator 20 coincides with the end of the epoxy unit 16, and it is not possible to feed deeper than that. However, in the case of the present application, since the pre-mold insulator 20 can be pulled through the press fitting 60, the spring 62, and the press ring 64, the pre-mold insulator 20 can be sent deeper than that by a simple pulling means.
そして、最終的には、その前面をエポキシユニツト16
に密着させる。And finally, the epoxy unit 16
In close contact.
プレモールド絶縁体20の移動を終えたら、板状押し治
具70を分解して、ケーブル線心10から取り外す。When the movement of the pre-mold insulator 20 is completed, the plate-shaped pressing jig 70 is disassembled and removed from the cable core 10.
