次にバネ座８を通し配電線に接続する絶縁電線９に圧着
した端子１０を締付ける。Next, the terminal 10 crimped onto the insulated wire 9 which is passed through the spring seat 8 and connected to the power distribution line is tightened.
絶縁カバー１１は絶縁電線９を通し、絶縁カバー１１の
突起部１１ａが、碍管１の端面に当るまで入れる。The insulated wire 9 is passed through the insulating cover 11 until the protrusion 11a of the insulating cover 11 touches the end face of the porcelain tube 1.
そして絶縁電線９と絶縁カバー１１をテープ１２でテー
ピングし絶縁カバー１１が動かないよう固定している。Then, the insulated wire 9 and the insulated cover 11 are taped with tape 12 to fix the insulated cover 11 so that it does not move.
しかし開閉器を長期間使用している間に絶縁電線９の被
覆と芯線がずれるため、絶縁カバー１１も被覆といっし
ょにずれ、バッキングカバー４が露出し絶縁カバー１１
の役目をはたさなくなる。However, while the switch is used for a long period of time, the sheath and core wire of the insulated wire 9 shift, and the insulating cover 11 also shifts together with the sheath, exposing the backing cover 4 and insulating cover 11.
It no longer plays the role of
そのため鳥や枯れ草等の飛来物が前記露出部にふれるこ
とにより短絡事故をおこすことがある。Therefore, flying objects such as birds and dry grass may come into contact with the exposed portion, causing a short circuit accident.
本考案は以上の欠点を除去して導電部が露出しないよう
、絶縁カバーのずれを確実に防止するブッシングを得る
ことを目的とする。The object of the present invention is to eliminate the above-mentioned drawbacks and provide a bushing that reliably prevents the insulating cover from shifting so that the conductive part is not exposed.
本考案の構造を第３図及び第４図に示す。The structure of the present invention is shown in FIGS. 3 and 4.
碍管１を貫通する導体２に防水用のバッキング３とバッ
キングカバー４、回り止め５、ストッパー１３、バネ座
６を順次導体２に通しナツトＩで締付は固定する。A waterproof backing 3, a backing cover 4, a detent 5, a stopper 13, and a spring seat 6 are sequentially passed through the conductor 2 passing through the insulator tube 1, and are tightened and fixed with a nut I.
次にバネ座８を通し配電線に接続する絶縁電線９に圧着
した端子１０を締付ける。Next, the terminal 10 crimped onto the insulated wire 9 which is passed through the spring seat 8 and connected to the power distribution line is tightened.
絶縁カバー１１は絶縁電線９を突起部１１ａがストッパ
ー１３に当らないようにして通し絶縁カバー１１の突起

縁カバー１１を９００まわして絶縁電線９にテープ１２
でテーピングし絶縁カバー１１が動かないよう固定する
。Pass the insulated wire 9 through the insulation cover 11 so that the protrusion 11a does not touch the stopper 13. At the position where the protrusion 11a of the insulation cover 11 touches the insulator side of the stopper 13, turn the insulation cover 11 900 degrees and tape the insulated wire 9. 12
Tape to fix the insulating cover 11 so that it does not move.
そして絶縁電線９の芯線と被覆の間で被覆がずれるのを
、ストッパー１３に絶縁カバー１１の突起部１１ａがか
かり絶縁カバー１１がずれるのを防ぐ。Then, the protrusion 11a of the insulating cover 11 is applied to the stopper 13 to prevent the insulating cover 11 from shifting between the core wire and the sheath of the insulated wire 9.
このようにすることにより絶縁カバーがずれるのを防ぎ
、導電部の露出がなくなり鳥や飛来物等による短絡事故
を防ぐことができる。By doing this, the insulating cover is prevented from shifting, and the conductive parts are not exposed, making it possible to prevent short circuit accidents caused by birds, flying objects, etc.
また導電部が露出しないため工事の面からも安全である
。It is also safer from a construction standpoint since no conductive parts are exposed.
変形例を第５図に示す。A modified example is shown in FIG.
この実施例は碍管１を貫通する導体２に防水用のバッキ
ング３とバッキングカバー４、バネ座６を通しナツト７
で締付は固定する。In this embodiment, a waterproof backing 3, a backing cover 4, and a spring seat 6 are passed through a conductor 2 passing through an insulator pipe 1, and a nut 7 is inserted.
Tighten to secure.
次に導体２のまわり止めを兼ねたストッパ１４を導体２
のくぼみ２ａに差込み、バネ座８を通して送電線に接続
する絶縁電線９に圧着した端子１０を締付ける。Next, attach the stopper 14 that also serves as a rotation stopper to the conductor 2.
Insert the terminal 10 into the recess 2a and tighten the crimped terminal 10 to the insulated wire 9 which is connected to the power transmission line through the spring seat 8.
