図３は、従来の電線絶縁カバーの構成を示す構成図である。図３において、従来の電線絶縁カバー２００は、２つ割れのカバー本体部１０がヒンジ２０により結合されて開閉を自在に行うことができる。また、２つ割れのカバー本体部１０の短手方向の端部の一方はカバー封止用のスナップ３０を、他方はカバー封止用のスナップ孔４０をそれぞれ有し、このスナップ３０とスナップ孔４０により、２つ割れのカバー本体部１０が閉じられて固定される。 FIG. 3 is a configuration diagram showing a configuration of a conventional electric wire insulation cover. In FIG. 3, the conventional electric wire insulation cover 200 can be opened and closed freely by the split cover main body 10 being coupled by a hinge 20. Also, one of the ends in the short direction of the split cover main body 10 has a cover sealing snap 30, and the other has a cover sealing snap hole 40. By 40, the cover main-body part 10 which is divided into two is closed and fixed.

端部にカバー封止用のスナップ３０を有する側のカバー本体部１０の内側には、電線（図示せず）に差し込まれる２組のツメ部５５を有している。また、当該端部は取付け時に絶縁ヤットコにより把持される絶縁ヤットコ把持部６０を具備している。   Two sets of claw portions 55 to be inserted into electric wires (not shown) are provided inside the cover main body portion 10 on the side having the cover sealing snaps 30 at the end portions. Moreover, the said edge part is equipped with the insulated-yaw grip part 60 hold | gripped with the insulated hat at the time of attachment.

図４は、従来の電線絶縁カバーの設置を示す設置工法図である。図４ａにおいて、電線絶縁カバー２００の取付けを間接活線工法で施工する場合、まず、電線絶縁カバー２００を開いた状態にし、絶縁ヤットコ８０により絶縁ヤットコ把持部６０を把持する。次に、２組のツメ部５５を電線７０に接近させる。図４ｂにおいて、２組のツメ部５５が電線７０を捉えると、電線７０が２組のツメ部５５に押し込まれるまで電線絶縁カバー２００を水平に移動させる。電線７０が２組のツメ部５５に完全に押し込まれると、電線絶縁カバー２００を閉じ、スナップ３０とスナップ孔４０により、固定する。   FIG. 4 is an installation method diagram showing installation of a conventional electric wire insulation cover.
