Description

本発明は、電線を絶縁カバーするための、ヒンジタイプの電線絶縁カバーに係り、詳しくは、電線絶縁カバーの取付け作業が容易となる電線絶縁カバーに関する。   The present invention relates to a hinge-type electric wire insulation cover for insulating an electric wire, and more particularly to an electric wire insulation cover that facilitates the work of attaching the electric wire insulation cover.

図５は、従来の電線絶縁カバーの構成を示す構成図である。図５ａ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１０−１、１０−２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１０−１の長手方向の端部はカバー封止用のスナップ３０を、２つ割れのカバー本体部１０−２の長手方向の端部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１０−１、１０−２が閉じられて固定される。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１０−１の内側には、電線（図示せず）に差し込まれる２組のフック５０を有している。図５ｂは、２つ割れのカバー本体部１０−１、１０−２がヒンジ２０を上側にして閉じられ、カバー封止用のスナップ３０とスナップ孔４０とが嵌合した状態を示している。   FIG. 5 is a configuration diagram showing a configuration of a conventional electric wire insulation cover. In FIG. 5a, the conventional electric wire insulation cover 200 can be opened and closed freely by combining the cover main body portions 10-1 and 10-2 which are split into two by the hinge 20. Further, the end portion in the longitudinal direction of the split cover body portion 10-1 is a cover sealing snap 30, and the end portion in the longitudinal direction of the split cover body portion 10-2 is a cover sealing. Each of the cover holes 10-1 and 10-2 is closed and fixed by the snap holes 40 and the snap holes 40. Two sets of hooks 50 to be inserted into electric wires (not shown) are provided on the inner side of the cover main body 10-1 on the side having the cover sealing snap 30 at the end. FIG. 5 b shows a state where the cover main body portions 10-1 and 10-2 that are split into two are closed with the hinge 20 on the upper side, and the cover sealing snap 30 and the snap hole 40 are fitted.

図６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６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、開口状態の電線絶縁カバー２００を絶縁ヤットコ８０により把持し、２組のフック５０により電線７０を捉える。次に、再び絶縁ヤットコ８０により、電線絶縁カバー２００を閉じスナップ３０とスナップ孔４０とを嵌合する操作を行う。   FIG. 6 is an installation method diagram showing installation of a conventional electric wire insulation cover. In FIG. 6, when installing the electric wire insulation cover 200 by the indirect hot wire method, first, the open electric wire insulation cover 200 is gripped by the insulation jacket 80 and the electric wires 70 are captured by the two sets of hooks 50. Next, an operation for closing the wire insulation cover 200 and fitting the snap 30 and the snap hole 40 is performed again with the insulating jacket 80.

ところがこの段階で絶縁ヤットコ８０により電線絶縁カバー２００を閉じようとすると、フック５０は電線７０を単に捕まえているだけであるため、電線絶縁カバー２００が電線７０を軸に回転するというトラブルが発生し、安定してスナップ３０とスナップ孔４０とを嵌合させることが困難となる。   However, if it is attempted to close the electric wire insulation cover 200 with the insulating Yatco 80 at this stage, the hook 50 merely catches the electric wire 70, and thus the trouble that the electric wire insulation cover 200 rotates around the electric wire 70 occurs. It becomes difficult to fit the snap 30 and the snap hole 40 stably.

特許文献１には、２つ割れのカバー本体部１０−１、２のいずれか一方の内側には、電線の絶縁被覆が部分的に除去された箇所の両側の絶縁被覆の切断部５５−１、２の片側にそれぞれ独立して嵌合する２組の横ズレ防止用のフック２０−１を含み、２組の横ズレ防止用のフック２０−１の各組は、２つの支持部２３から構成され、２つの支持部２３の各々は、絶縁被覆の切断部５５−１、２に嵌合する嵌合部２５と、絶縁被覆が部分的に除去された導体部５０の外径に対し自在に適合し把持する内面溝２７を具備し、各組の２つの支持部２３は、嵌合部２５が互いに絶縁被覆の切断部５５−１、２の片側に嵌合し、内面溝２７が互いに導体部５０を把持する位置に、２つ割れのカバー本体部１０−２の内側の長手方向の中心線に対向して設置される、旨の記載がある。   In Patent Document 1, the insulating coating cutting portions 55-1 on both sides of the part where the insulating coating of the electric wire is partially removed is provided inside one of the two split cover main body portions 10-1, 2. 2 sets of two lateral displacement prevention hooks 20-1, each of which is independently fitted to one side of each of the two pairs. Each of the two support portions 23 is free to the outer diameter of the fitting portion 25 fitted to the cut portions 55-1 and 2 of the insulating coating and the conductor portion 50 from which the insulating coating is partially removed. The two support portions 23 of each set are fitted to one side of the insulating coating cutting portions 55-1 and 2 and the inner groove 27 is mutually connected. At the position where the conductor part 50 is gripped, it is arranged opposite the center line in the longitudinal direction inside the cover main body part 10-2 which is split into two. Is the, there is a fact described.

本発明の実施の形態について、図を用いて説明する。図１は、本発明による電線絶縁カバーの構成を示す構成図である。図１において、電線絶縁カバー１００は、端部にカバー封止用のスナップ３０を有するカバー本体部１０−１の内側における２組のフック５０の内部に、電線絶縁カバー１０−１．２が電線７０を軸に回転することを防止する回転防止機構であるリブ５５を有している点が図３と異なり、他は同様であるため、重複する部分の説明は省略する。つぎに、この回転防止機構について詳細に説明する。   Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of a wire insulation cover according to the present invention. In FIG. 1, the wire insulation cover 100 includes a wire insulation cover 10-1.2 inside the two sets of hooks 50 inside the cover main body 10-1 having a cover sealing snap 30 at the end. 3 is different from FIG. 3 in that it has a rib 55 that is a rotation prevention mechanism for preventing rotation about the axis 70, and the description of the overlapping part is omitted. Next, the rotation preventing mechanism will be described in detail.

図２は、本発明の電線絶縁カバーの回転防止機構を示す構成図である。図２ａは、２つ割れのカバー本体部１０−１、１０−２がヒンジ２０を上側にして閉じられ、カバー封止用のスナップ３０とスナップ孔４０とが嵌合した状態を示している。図２ａにおいて、回転防止機構であるリブ５５は、フック５０の凹部５１上に、電線７０の中心軸方向に撚られて形成される撚線が中心軸と成す角度に対応する傾斜角を有して構成されている。図２ｂは、図２ａにおけるＡＡ断面図である。図２ｂにおいて、リブ５５は、電線７０の撚線の中心軸と平行を成す一点鎖線と、撚られて形成された撚線との角度（撚線角度α）に対応した角度に構成されている。   FIG. 2 is a configuration diagram showing a rotation prevention mechanism for the electric wire insulation cover of the present invention. FIG. 2 a shows a state in which the cover main body portions 10-1 and 10-2 that are split into two are closed with the hinge 20 facing upward, and the cover sealing snap 30 and the snap hole 40 are fitted. In FIG. 2a, the rib 55, which is a rotation prevention mechanism, has an inclination angle corresponding to the angle formed by the stranded wire formed by twisting in the central axis direction of the electric wire 70 on the concave portion 51 of the hook 50. Configured. FIG. 2b is a cross-sectional view taken along line AA in FIG. 2a. In FIG. 2b, the rib 55 is configured at an angle corresponding to an angle (a stranded wire angle α) between a one-dot chain line that is parallel to the central axis of the stranded wire of the electric wire 70 and a stranded wire formed by twisting. .

図３は、本発明によるフックの電線把持状態を示す電線把持図である。図３において、フック５０は、対向する凹部５１により、電線７０の被覆が取り除かれた撚線を把持している。また、リブ５５は、電線７０の撚線の、撚られて形成される撚線角度αに沿って、互いに隣接する撚線の間に密着している。   FIG. 3 is a wire gripping diagram showing the wire gripping state of the hook according to the present invention. In FIG. 3, the hook 50 holds the stranded wire from which the coating of the electric wire 70 is removed by the opposing recess 51. Further, the rib 55 is in close contact with the adjacent twisted wires along the twisted wire angle α formed by twisting the twisted wires of the electric wire 70.

図４は、本発明による電線絶縁カバーの設置を示す設置工法図である。図４において、電線絶縁カバー１００の取付けを間接活線工法で施工する場合、図６と同様に、開口状態の電線絶縁カバー１００を絶縁ヤットコ８０により把持し、２組のフック５０により電線７０を捉える。このとき、フック５０、及びリブ５５は、図３に示される状態となっている。次に、再び絶縁ヤットコ８０により、電線絶縁カバー２００を閉じスナップ３０とスナップ孔４０とを嵌合する操作を行う。   FIG. 4 is an installation method diagram showing installation of the electric wire insulation cover according to the present invention. In FIG. 4, when the electric wire insulation cover 100 is attached by the indirect hot wire method, the open electric wire insulation cover 100 is gripped by the insulation jacket 80 and the electric wire 70 is attached by the two sets of hooks 50 as in FIG. 6. Capture. At this time, the hook 50 and the rib 55 are in the state shown in FIG. Next, the electric wire insulating cover 200 is closed again by the insulating jacket 80, and the snap 30 and the snap hole 40 are engaged.

このように、絶縁ヤットコ８０で電線絶縁カバー１００を閉じる場合、リブ５５が隣接する撚線の間に完全に密着しているため、電線絶縁カバー１００が電線７０を軸に回転するというトラブルは発生せず、安定してスナップ３０とスナップ孔４０とを嵌合させることができる。   Thus, when closing the electric wire insulation cover 100 with the insulating Yatco 80, since the rib 55 is completely adhered between adjacent stranded wires, the trouble that the electric wire insulation cover 100 rotates around the electric wire 70 occurs. Without being able to fit, the snap 30 and the snap hole 40 can be fitted stably.

以上説明したように本発明によれば、ヒンジタイプの電線絶縁カバーの取付け作業が容易となる電線絶縁カバーを提供することができる。   As described above, according to the present invention, it is possible to provide a wire insulation cover that facilitates the installation work of a hinge-type wire insulation cover.
