次に、絶縁用端末キャップ１０の使用方法について、図２（ａ）〜（ｃ）を参照して説明する。
架空電線１の端末部を横向きにして絶縁用端末キャップ１０に被せる場合には、挿入確認部材２０の外側円板２１とキャップ本体１１とが当接するまで、挿入確認部材２０をキャップ本体１１に向かって押し込む（図２（ａ）の白抜き矢印参照）。
これにより、挿入確認部材２０の円環板２４がキャップ本体１１の貫通孔１１ａを貫通してキャップ本体１１内に押し入れられる。
Next, a method of using the insulating end cap 10 will be described with reference to FIGS. 2 (a) to 2 (c).
When the end portion of the overhead electric wire 1 is placed on the terminal cap 10 for insulation sideways, the insertion confirmation member 20 is moved toward the cap main body 11 until the outer disc 21 of the insertion confirmation member 20 and the cap main body 11 abut. (See white arrow in FIG. 2 (a)).
As a result, the annular plate 24 of the insertion confirmation member 20 penetrates the through hole 11 a of the cap body 11 and is pushed into the cap body 11.
続いて、架空電線１の端末部の先端面が挿入確認部材２０の内側円板２２に当接し挿入確認部材２０全体がキャップ本体１１の先端部に向かって押されて内側円板２２とキャップ本体１１とが当接するまで、架空電線１の端末部をキャップ本体１１の蓋１２を通してキャップ本体１１に挿入する（図２（ａ）の白抜き矢印参照）。
これにより、挿入確認部材２０の円環板２４がキャップ本体１１の貫通孔１１ａを貫通してキャップ本体１１外に押し出されるとともに、挿入確認部材２０の連結棒２３の大部分がキャップ本体１１外に押し出されるため（図２（ｂ）の矢印参照）、架空電線１の端末部が絶縁用端末キャップ１０に完全に挿入されたことを一目で確認することができる。
Subsequently, the tip end surface of the end portion of the overhead wire 1 abuts on the inner disc 22 of the insertion confirmation member 20, and the entire insertion confirmation member 20 is pushed toward the tip end of the cap main body 11, and the inner disc 22 and the cap main body The end portion of the overhead wire 1 is inserted into the cap body 11 through the lid 12 of the cap body 11 until it abuts on the cap 11 (see the white arrow in FIG. 2A).
Thereby, the annular plate 24 of the insertion confirmation member 20 penetrates the through hole 11 a of the cap main body 11 and is pushed out of the cap main body 11, and most of the connecting rod 23 of the insertion confirmation member 20 is outside the cap main body 11 Since it is pushed out (see the arrow in FIG. 2B), it can be confirmed at a glance that the end of the overhead wire 1 is completely inserted into the insulating end cap 10.
その後、架空電線１の工事が終って架空電線１の端末部を絶縁用端末キャップ１０から外すと、挿入確認部材２０の外側円板２１とキャップ本体１１とが当接するまで挿入確認部材２０をキャップ本体１１に向かって押し込んでおくことにより、絶縁用端末キャップ１０を再利用することができる。 Thereafter, when the construction of the overhead wire 1 is finished and the end portion of the overhead wire 1 is removed from the insulating end cap 10, the insertion confirmation member 20 is capped until the outer disc 21 of the insertion confirmation member 20 and the cap main body 11 abut. The insulating terminal cap 10 can be reused by pressing it toward the main body 11.
架空電線１の端末部を上向きにして絶縁用端末キャップ１０に被せる場合にも、架空電線１の端末部を横向きに絶縁用端末キャップ１０に挿入する場合と同様の作業手順を行うことにより、架空電線１の端末部が絶縁用端末キャップ１０に完全に挿入されたことを一目で確認することができる。 Even when the end portion of the overhead wire 1 is faced upward and covered on the insulating end cap 10, the same operation procedure as in the case of inserting the end portion of the overhead wire 1 sideways into the insulating end cap 10 is performed. It can be confirmed at a glance that the end of the electric wire 1 is completely inserted into the insulating end cap 10.
また、架空電線１の工事では、切断した架空電線１の端末部を下向きにして絶縁用端末キャップ１０に挿入する場合もあるが、この場合には、キャップ本体１１の先端部を下にした状態で絶縁用端末キャップ１０を架空電線１の端末部に被せることになるため、挿入確認部材２０に円環板２４が取り付けられていないと、挿入確認部材２０が外側円板２１の重さで落ちてしまう結果（図２（ｃ）の矢印参照）、架空電線１の端末部が絶縁用端末キャップ１０に完全に挿入されたことを確認することができなくなる。
そこで、挿入確認部材２０に円環板２４を取り付けることにより、図２（ｃ）に示すように円環板２４によって挿入確認部材２０が外側円板２１の重さで落ちてしまうことを防止することができるため、上述した架空電線１の端末部を横向きに絶縁用端末キャップ１０に挿入する場合と同様の作業手順を行うことにより、架空電線１の端末部が絶縁用端末キャップ１０に完全に挿入されたことを一目で確認することができる。
In addition, in the construction of the overhead wire 1, there is a case where the end portion of the disconnected overhead wire 1 is turned downward and inserted into the insulating end cap 10, but in this case, the end portion of the cap main body 11 is down. Since the terminal cap 10 for insulation is put on the end of the overhead electric wire 1, if the annular plate 24 is not attached to the insertion confirmation member 20, the insertion confirmation member 20 falls by the weight of the outer disc 21. As a result (refer to the arrow in FIG. 2C), it can not be confirmed that the end portion of the overhead wire 1 is completely inserted into the insulating end cap 10.
Therefore, by attaching the annular plate 24 to the insertion confirmation member 20, it is possible to prevent the insertion confirmation member 20 from being dropped by the weight of the outer disc 21 by the annular plate 24 as shown in FIG. Therefore, by performing the same operation procedure as in the case where the end of the overhead wire 1 described above is inserted laterally into the end cap 10 for insulation, the end of the overhead wire 1 is completely attached to the end cap 10 for insulation You can confirm at a glance that it has been inserted.
絶縁用端末キャップ１０は架空電線以外の電線の端末絶縁処理にも使用することができるが、切断した電線の端末部を下向きにして絶縁用端末キャップ１０に挿入する場合がないときには、挿入確認部材２０に円環板２４を取り付けなくてもよい。 Although the terminal cap 10 for insulation can be used also for the terminal insulation processing of the electric wire other than the overhead electric wire, when the terminal part of the cut electric wire faces down and can not be inserted into the terminal cap 10 for insulation, the insertion confirmation member The annular plate 24 may not be attached to 20.
