Description

本発明は、架空送電線など配電線路の充電露出箇所に装着する配電線用絶縁カバーに関する。   The present invention relates to an insulating cover for a distribution line that is attached to a charging exposed portion of a distribution line such as an overhead power transmission line.

架空送電線など配電線路の充電露出箇所には、引留クランンプカバー、スリーブカバー等の絶縁カバーが施される。従来、絶縁カバーの取付けには、作業者が防護服を着用し、手で直接取付けることも行われていたが、今日では、ホットスティック、ヤットコなどの間接活線工具を使用した間接活線工法と呼ばれる方法で実施されることが一般的である。   Insulation covers such as a retention clamp cover and a sleeve cover are applied to exposed portions of the distribution line such as an overhead power transmission line. In the past, workers used to wear protective clothing and attach directly by hand to install the insulation cover, but today, an indirect hot line method using an indirect hot wire tool such as a hot stick or Yatco. It is common to implement by the method called.

一般的な絶縁カバーは、配電線を覆う左右一対のカバーを備え、カバーの端部に爪（突起）及び爪が係止する係止孔を設け、爪を係止孔に係止することでカバーを閉じ、配電線に装着される（例えば特許文献１、特許文献２参照）。従来の絶縁カバーは、配電線への装着は比較的容易であるが、元々、配電線からの取外しが考慮されていないため取外しは容易ではない。特に、間接活線工具を用いた取外し作業は難しい。   A typical insulating cover includes a pair of left and right covers that cover the distribution line, and a claw (projection) and a locking hole for locking the claw are provided at the end of the cover, and the claw is locked to the locking hole. The cover is closed and attached to the distribution line (see, for example, Patent Document 1 and Patent Document 2). Although the conventional insulation cover is relatively easy to attach to the distribution line, it is not easy to remove because the removal from the distribution line is not originally considered. In particular, the removal work using an indirect hot wire tool is difficult.

このような問題を解決すべく、着脱容易な配電線用絶縁カバーが開発されている（例えば特許文献３参照）。特許文献３に記載の配電線用絶縁カバーは、カバーを閉じるための係止ボタン及び係止ボタンが係止する段付孔の他に、取外し用の突起を備える。このためホットスティックを使用して簡単に取外すことができる。   In order to solve such a problem, an insulating cover for a distribution line that can be easily attached and detached has been developed (see, for example, Patent Document 3). The insulating cover for distribution lines described in Patent Document 3 includes a protrusion for removal in addition to a locking button for closing the cover and a stepped hole for locking the locking button. For this reason, it can be easily removed using a hot stick.

実開平７−２９７１９号公報Japanese Utility Model Publication No. 7-29719 特開平１０−６６２３５号公報Japanese Patent Laid-Open No. 10-66235 特許第４５５３２０２号公報Japanese Patent No. 4553202

特許文献１に記載の絶縁カバーは、比較的大きな爪を使用しているためカバーをしっかりと閉じ、配電線に固定することができる。しかし、この絶縁カバーは、配電線に装着した状態から間接活線工具を用いて取外すことが難しい。   Since the insulating cover described in Patent Document 1 uses relatively large claws, the cover can be firmly closed and fixed to the distribution line. However, it is difficult to remove this insulating cover using an indirect hot wire tool from the state where it is attached to the distribution line.

一方、特許文献３に記載の配電線用絶縁カバーは、配電線への装着、配電線からの取外しは容易である。しかし、カバーを閉じるために使用する係止ボタンの段付孔に対する係止代が小さいため取付け易い一方で外れ易い。また絶縁カバーが捩れ、左右のカバー部材の位置がずれてしまうと、係止ボタンが段付孔に臨まず、嵌合が難しくなる。無理に嵌め入れようとすると係止ボタンがカバー部材にぶつかり変形する恐れがある。   On the other hand, the insulating cover for distribution lines described in Patent Document 3 can be easily attached to the distribution line and removed from the distribution line. However, since the locking allowance with respect to the stepped hole of the locking button used for closing the cover is small, it is easy to install but easy to come off. Further, if the insulating cover is twisted and the positions of the left and right cover members are displaced, the locking button does not face the stepped hole, and the fitting becomes difficult. If it is forced to fit, the locking button may hit the cover member and be deformed.

以上のようにこれまでに開発されている配電線用絶縁カバーは、配電線へ装着したときにしっかりと固定できるタイプのものは、間接活線工具を使用した着脱作業が難しく、逆に、間接活線工具を使用した着脱作業が容易なタイプのものは、配電線へ装着したときの保持力が弱く外れ易い。特許文献１と特許文献３に記載の技術を組み合わせることで、両方の利点を活かした配電線用絶縁カバーとすることも考えられるが、これらを単に組み合わせただけでは、配電線へ装着したときにしっかりと固定され、かつ間接活線工具を使用した着脱作業が容易な配電線用絶縁カバーとはならない。   As described above, the insulation cover for distribution lines that has been developed so far is difficult to attach and detach using an indirect hot wire tool if it can be firmly fixed when attached to the distribution line. A type that is easy to attach and detach using a hot wire tool has a weak holding force when attached to a distribution line and is easily detached. By combining the techniques described in Patent Document 1 and Patent Document 3, it is possible to make an insulating cover for a distribution line that takes advantage of both, but when these are simply combined, It is not an insulation cover for distribution lines that is firmly fixed and easy to attach and detach using an indirect hot wire tool.

本発明の目的は、配電線へ装着したときにしっかりと固定され、かつ間接活線工具を使用した着脱作業が容易な配電線用絶縁カバーを提供することである。   An object of the present invention is to provide an insulating cover for a distribution line that is firmly fixed when attached to the distribution line and that can be easily attached and detached using an indirect hot wire tool.

本発明は、配電線を覆う左右一対のカバー部材の上端をヒンジを介して回動自在に結合し、前記左右一対のカバー部材の下端部に前記カバー部材を開閉自在に係止させる係止手段を備える配電線用絶縁カバーにおいて、前記係止手段は、一方のカバー部材の下端部に設けられた、係止孔が穿設された舌片状の第１係止片と、他方のカバー部材の下端部に設けられた、前記係止孔に係止する係止爪を備える舌片状の第２係止片と、を有し、前記第１係止片及び前記第２係止片は、前記カバー部材に対して内側に傾斜して形成され、前記係止爪を前記係止孔に係止すると前記係止爪が前記係止孔から突出し、前記第１係止片と前記第２係止片とが前記カバー部材に対して略４５°の角度で互いに直交し、前記第２係止片の先端部は、前記係止孔よりも小さく、前記係止爪は、先端側から前記係止孔に係止する根元部分の係止部にかけて徐々に幅広に、かつ徐々に高さが高くなるように形成されていることを特徴とする配電線用絶縁カバーである。 The present invention provides a locking means for connecting the upper ends of a pair of left and right cover members covering a distribution line through a hinge so as to be rotatable, and locking the cover members to the lower ends of the pair of left and right cover members so as to be opened and closed In the insulating cover for distribution lines, the locking means includes a tongue-shaped first locking piece provided with a locking hole provided at a lower end portion of one cover member, and the other cover member. A tongue-shaped second locking piece provided with a locking claw that locks in the locking hole, and the first locking piece and the second locking piece are And the cover member is inclined inward, and when the locking claw is locked in the locking hole, the locking claw protrudes from the locking hole, and the first locking piece and the second a locking piece are orthogonal to each other at an angle of approximately 45 ° with respect to the cover member, the distal end portion of the second engaging piece, the locking hole Is small, the locking claw has a feature in that the engagement gradually wider toward engagement portion of the root portion for engaging the locking hole, and is formed so as to gradually height increases from the front end side This is an insulating cover for distribution lines.

本発明の配電線用絶縁カバーは、カバー部材を開閉自在に係止させる係止手段が、第１係止片及び第２係止片を有し、第１係止片と第２係止片とを係止させると、係止爪が係止孔から突出し、第１係止片と第２係止片とがカバー部材に対して４５°の角度で内側に傾斜し、互いに直交するので、間接活線工具を使用して第１係止片及び第２係止片の係止を簡単に外すことができる。また係止爪を係止孔から突出するように嵌め入れるので、配電線へ装着したときにしっかりと固定される。さらに係止爪が係止孔に係止したことが分かり易いので、配電線用絶縁カバー装着後の出来上がりを確認し易い。
また本発明の配電線用絶縁カバーは、第２係止片の先端部が係止孔よりも小さく、さらに先端部に続く係止爪が大略的には先細楔形状を有するので、左右のカバー部材同士が少しずれていても、第２係止片の先端部が係止孔に臨み、係止爪が係止孔にスムーズに係止される。このため簡単に取付けることができる。 In the insulating cover for distribution lines according to the present invention, the locking means for locking the cover member so as to be opened and closed has a first locking piece and a second locking piece, and the first locking piece and the second locking piece. Since the locking claw protrudes from the locking hole, the first locking piece and the second locking piece are inclined inward at an angle of 45 ° with respect to the cover member, and are orthogonal to each other. The first locking piece and the second locking piece can be easily unlocked using an indirect hot wire tool. Further, since the locking claw is fitted so as to protrude from the locking hole, it is firmly fixed when mounted on the distribution line. Furthermore, since it is easy to understand that the locking claw is locked in the locking hole, it is easy to confirm the completion after the distribution line insulating cover is mounted.
In the insulating cover for power distribution lines according to the present invention, the distal end of the second locking piece is smaller than the locking hole, and the locking claw following the distal end generally has a tapered wedge shape. Even if the members are slightly shifted from each other, the distal end portion of the second locking piece faces the locking hole, and the locking claw is smoothly locked in the locking hole. This makes it easy to install.

また本発明において、前記第１係止片及び前記第２係止片は、左右の前記カバー部材を閉じるように回動させたときに前記第２係止片の先端部が前記係止孔に挿入され、かつ、前記第２係止片の先端部が前記係止孔から突出するように形成されていることを特徴とする。   Further, in the present invention, when the first locking piece and the second locking piece are rotated so as to close the left and right cover members, the tip end portion of the second locking piece becomes the locking hole. It is inserted and it is formed so that the front-end | tip part of the said 2nd locking piece may protrude from the said locking hole.

本発明の配電線用絶縁カバーは、左右の前記カバー部材を閉じるように回動させたときに第２係止片の先端部が係止孔に挿入され、かつ、第２係止片の先端部が係止孔から突出するように形成されているので、係止孔の外側から第２係止片の先端を間接活線工具により把持して又は引掛けて引っ張ることで係止爪を係止孔に容易に係止させることができる。このため簡単に取付けることができる。   In the insulating cover for distribution lines of the present invention, when the left and right cover members are rotated so as to be closed, the tip end portion of the second locking piece is inserted into the locking hole, and the tip end of the second locking piece Since the portion is formed so as to protrude from the locking hole, the tip of the second locking piece is gripped or pulled by an indirect live tool from the outside of the locking hole to engage the locking claw. It can be easily locked in the stop hole. This makes it easy to install.

また本発明において、前記第１係止片は、先端から前記係止孔にかけて前記第２係止片の先端部が通過可能な溝を備え、前記溝は、幅が少なくとも前記第２係止片の先端から前記係止爪にかけての幅よりも広く、かつ、少なくとも前記係止孔に係止する前記係止爪の根元部分の係止部の幅よりも狭く、前記第２係止片の先端部は、左右の前記カバー部材を閉じたときに前記係止孔に代えて前記溝に挿入され、前記溝から突出することを特徴とする。   In the present invention, the first locking piece includes a groove through which the tip of the second locking piece can pass from the tip to the locking hole, and the groove has at least the width of the second locking piece. The tip of the second locking piece is wider than the width from the tip of the locking claw to the locking claw and at least narrower than the width of the locking portion at the base portion of the locking claw locked to the locking hole. The portion is inserted into the groove instead of the locking hole when the left and right cover members are closed, and protrudes from the groove.

本発明の配電線用絶縁カバーは、第１係止片が、先端から係止孔にかけて第２係止片の先端部が通過可能な溝を備えるので、第２係止片の先端部を間接活線工具により把持して又は引掛けて第２係止片の先端部を溝に通しながら引っ張ることで係止爪を係止孔に容易に係止させることができる。このため簡単に取付けることができる。   In the insulating cover for distribution lines according to the present invention, the first locking piece includes a groove through which the tip of the second locking piece can pass from the tip to the locking hole, so that the tip of the second locking piece is indirect. By holding or hooking with a live tool and pulling the tip of the second locking piece through the groove, the locking claw can be easily locked in the locking hole. This makes it easy to install.

また本発明において、前記第１係止片の先端から前記係止孔までの間及び／又は前記第２係止片の先端から前記係止爪までの間には、バインド打ち器のフックが引っ掛かる工具引掛孔が設けられていることを特徴とする。   In the present invention, the hook of the bind hammer is caught between the tip of the first locking piece and the locking hole and / or between the tip of the second locking piece and the locking claw. A tool hooking hole is provided.

本発明の配電線用絶縁カバーは、バインド打ち器を使用して簡単に装着又は取外しを行うことができる。   The insulating cover for distribution lines according to the present invention can be easily mounted or removed using a bind hammer.

また本発明において、前記第１係止片及び前記第２係止片は、係止時に互いの先端の高さが略同一になるように形成されていることを特徴とする。   Moreover, in this invention, the said 1st locking piece and the said 2nd locking piece are formed so that the height of a mutual tip may become substantially the same at the time of latching.

本発明の配電線用絶縁カバーは、第１係止片及び第２係止片が、係止時に互いの先端の高さが略同一になるように形成されているので、ヤットコで把持して取外す作業を低位置から容易に行うことができる。   In the insulating cover for distribution lines according to the present invention, the first locking piece and the second locking piece are formed so that the heights of the tips of the first locking piece and the second locking piece are substantially the same when locked. The removal work can be easily performed from a low position.

本発明の配電線用絶縁カバーは、配電線へ装着したときにしっかりと固定され、かつ間接活線工具を使用した着脱作業が容易である。   The insulating cover for distribution lines of the present invention is firmly fixed when attached to the distribution line, and is easy to attach and detach using an indirect hot wire tool.

This inclination angle is such that the distal end portion 34 of the second locking piece 32 is locked when the right cover member 11 and the left cover member 12 are turned inward (in the direction of closing the right cover member 11 and the left cover member 12). It is determined to be inserted into the hole 23 and to protrude outward from the locking hole 23.

第１係止片２２及び第２係止片３２は、係止時に互いの先端が略同一の高さとなるように、略同一の長さで形成されている。ここで第１係止片２２及び第２係止片３２の係止時の互いの先端の高さ関係は、後述するヤットコ５７による取外し時に第１係止片２２及び第２係止片３２の両方の先端を低位置からヤットコ５７で把持し易い高さ関係であればよい。   The first locking piece 22 and the second locking piece 32 are formed with substantially the same length so that the tips of the first locking piece 22 and the second locking piece 32 have substantially the same height when locked. Here, the height relationship between the tips of the first locking piece 22 and the second locking piece 32 when the first locking piece 22 and the second locking piece 32 are locked is such that the first locking piece 22 and the second locking piece 32 are removed when the first locking piece 22 and the second locking piece 32 are removed by a YATCO 57 described later. Any height relationship may be used as long as both ends are easily gripped by the Yatco 57 from a low position.

係止孔２３は、矩形に形成されており、右側カバー部材１１の底部１６及び左側カバー部材１２の底部２０の先端が突き当たった状態において、第２係止片３２の外側の面が係止孔２３の先端部２４側の内周面に平行に当接するように配置されている。また係止孔２３は、係止爪３３が通過可能な大きさに穿設されている。   The locking hole 23 is formed in a rectangular shape, and the outer surface of the second locking piece 32 is the locking hole when the bottom 16 of the right cover member 11 and the tip of the bottom 20 of the left cover member 12 are in contact with each other. It arrange | positions so that it may contact | abut to the internal peripheral surface by the side of the front-end | tip part 24 of 23 in parallel. The locking hole 23 is drilled to a size that allows the locking claw 33 to pass therethrough.

係止爪３３は、係止孔２３を通過し易いように先端部３４側から係止孔２３に係止する根元部分の係止部３６にかけて徐々に幅広に且つ徐々に高さが高くなるように先細楔形状に形成されている。また第２係止片３２の先端部３４は、係止孔２３よりも小さく形成されている。   The locking claw 33 is gradually widened and gradually increased in height from the distal end portion 34 side to the locking portion 36 of the root portion locked to the locking hole 23 so as to easily pass through the locking hole 23. Are formed in a tapered wedge shape. Further, the distal end portion 34 of the second locking piece 32 is formed smaller than the locking hole 23.

このように係止爪３３が先細楔形状であり、第２係止片３２の先端部３４が係止孔２３よりも小さく形成されているので、右側カバー部材１１と左側カバー部材１２とが互いに少しずれていても第２係止片の先端部３４が係止孔２３に臨み、係止爪３３が係止孔２３にスムーズに係止される。   As described above, the locking claw 33 has a tapered wedge shape, and the distal end portion 34 of the second locking piece 32 is formed smaller than the locking hole 23. Therefore, the right cover member 11 and the left cover member 12 are mutually connected. Even if it is slightly deviated, the distal end portion 34 of the second locking piece faces the locking hole 23, and the locking claw 33 is smoothly locked in the locking hole 23.

係止時には右側カバー部材１１の底部１６の先端と左側カバー部材１２の底部２０の先端とが突き当たることで、係止爪３３と係止孔２３とが係止された状態に保持されるので、係止爪３３の係止部３６は、係止孔２３よりも若干小さくしても係止可能であり、少なくとも上端が係止孔２３に係止可能な高さに形成されていればよい。   Since the tip of the bottom 16 of the right cover member 11 and the tip of the bottom 20 of the left cover member 12 abut at the time of locking, the locking claw 33 and the locking hole 23 are held in a locked state. The locking portion 36 of the locking claw 33 can be locked even if it is slightly smaller than the locking hole 23, and it is sufficient that at least the upper end is formed at a height that can be locked to the locking hole 23.

第２係止片３２の先端部３４の長さ及び工具引掛孔３５の穿設位置は、右側カバー部材１１及び左側カバー部材１２が内側に回動し、第２係止片３２の先端部３４が係止孔２３へ挿入され係止孔２３と係止爪３３とが当接したときに工具引掛孔３５が係止孔２３（第１係止片２２）の外側に位置するように決められる。このようにすると、第２係止片３２の先端部３４が係止孔２３へ挿入された状態でバインド打ち器５５のフック５６を係止孔２３（第１係止片２２）の外側から引掛けることができる。   The length of the distal end portion 34 of the second locking piece 32 and the drilling position of the tool hooking hole 35 are such that the right cover member 11 and the left cover member 12 rotate inward, and the distal end portion 34 of the second locking piece 32 is rotated. Is inserted into the locking hole 23 and the tool hooking hole 35 is determined to be positioned outside the locking hole 23 (first locking piece 22) when the locking hole 23 and the locking claw 33 come into contact with each other. . In this way, the hook 56 of the bind hammer 55 is pulled from the outside of the locking hole 23 (first locking piece 22) with the tip 34 of the second locking piece 32 inserted into the locking hole 23. Can be hung.

次に本実施形態の配電線用絶縁カバー１の装着方法について説明する。図５（ａ）は、第２係止片３２の工具引掛孔３５にバインド打ち器５５を引掛けた状態を示す概略図である。図５（ｂ）は、バインド打ち器５５を用いて係止爪３３を係止孔２３に係止させた状態を示す概略図である。なお図５以降では、仮想線を省略している。   Next, a method for mounting the distribution line insulating cover 1 according to the present embodiment will be described. FIG. 5A is a schematic view showing a state in which the bind hitter 55 is hooked on the tool hooking hole 35 of the second locking piece 32. FIG. 5B is a schematic view showing a state in which the locking claw 33 is locked in the locking hole 23 using the bind hammer 55. In FIG. 5 and subsequent figures, virtual lines are omitted.

配電線用絶縁カバー１をヒンジ３７が上になるように配電線５１に被せ、自重により、又はヤットコ５７を用いて右側カバー部材１１及び左側カバー部材１２を、係止孔２３に係止爪３３が当接するまで内側に回動させる。   The distribution line insulating cover 1 is placed on the distribution line 51 so that the hinge 37 is on top, and the right cover member 11 and the left cover member 12 are locked by the dead weight or using the YATCO 57, and the locking claw 33 is locked in the locking hole 23. Rotate inward until abuts.

第２係止片３２の先端部３４が係止孔２３に挿入され、第２係止片３２の工具引掛孔３５が係止孔２３から突出する。突出した第２係止片３２の工具引掛孔３５にバインド打ち器５５のフック５６を引掛けて第２係止片３２を外側に引っ張ると係止爪３３が係止孔２３を通過し、係止爪３３の係止部３６が係止孔２３の端部に係止する。   The distal end portion 34 of the second locking piece 32 is inserted into the locking hole 23, and the tool hooking hole 35 of the second locking piece 32 protrudes from the locking hole 23. When the hook 56 of the bind hammer 55 is hooked on the tool hooking hole 35 of the protruding second locking piece 32 and the second locking piece 32 is pulled outward, the locking claw 33 passes through the locking hole 23, The locking portion 36 of the pawl 33 is locked to the end of the locking hole 23.

係止爪３３を係止孔２３に係止させると、右側カバー部材１１の底部１６の先端と左側カバー部材１２の底部２０の先端とが突き当たり、第１係止片２２と第２係止片３２とがそれぞれ右側カバー部材１１及び左側カバー部材１２の中央部１４、１８（ヒンジ３７の中心を通る鉛直線）に対して４５°の角度を有した状態で互いに直交する。   When the locking claw 33 is locked in the locking hole 23, the tip of the bottom portion 16 of the right cover member 11 and the tip of the bottom portion 20 of the left cover member 12 come into contact, and the first locking piece 22 and the second locking piece. 32 are orthogonal to each other with an angle of 45 ° with respect to the central portions 14 and 18 (vertical lines passing through the center of the hinge 37) of the right cover member 11 and the left cover member 12, respectively.

このように本実施形態の配電線用絶縁カバー１は、間接活線工具を用いて配電線５１に容易に装着することができ、係止爪３３が係止孔２３にしっかりと係止される。なお説明では、バインド打ち器５５を用いたが、突出した第２係止片３２の先端部３４をヤットコ５７で把持して引っ張り、係止爪３３を係止孔２３に係止させてもよい。   As described above, the insulating cover 1 for the distribution line according to the present embodiment can be easily attached to the distribution line 51 using an indirect hot wire tool, and the locking claw 33 is firmly locked in the locking hole 23. . In the description, the bind hitting device 55 is used. However, the protruding end portion 34 of the second locking piece 32 may be held and pulled by the Yatco 57 and the locking claw 33 may be locked in the locking hole 23. .

次に本実施形態の電線用絶縁カバー１の取外し方法について説明する。図６（ａ）は、第１係止片２２の工具引掛孔２５にバインド打ち器５５を引掛けた状態を示す概略図である。図６（ｂ）は、バインド打ち器５５を用いて係止爪３３を係止孔２３から外した状態を示す概略図である。   Next, the removal method of the insulating cover 1 for electric wires of this embodiment is demonstrated. FIG. 6A is a schematic view showing a state in which the bind hammer 55 is hooked on the tool hooking hole 25 of the first locking piece 22. FIG. 6B is a schematic view showing a state in which the locking claw 33 is removed from the locking hole 23 using the bind hammer 55.

バインド打ち器５５のフック５６を第１係止片２２の工具引掛孔２５に引掛けて第１係止片２２を外側に引っ張ると、右側カバー部材１１の底部１６の先端と左側カバー部材１２の底部２０の先端との突き当たりが外れ、左側カバー部材１２の下部１９が弾性力により内側に回動し係止爪３３が係止孔２３から外れ、配電線用絶縁カバー１を配電線５１から取外すことができる。   When the hook 56 of the bind hammer 55 is hooked on the tool hooking hole 25 of the first locking piece 22 and the first locking piece 22 is pulled outward, the tip of the bottom 16 of the right cover member 11 and the left cover member 12 The contact with the tip of the bottom portion 20 is released, the lower portion 19 of the left cover member 12 is rotated inward by elastic force, the locking claw 33 is removed from the locking hole 23, and the distribution line insulating cover 1 is removed from the distribution line 51. be able to.

また図７（ａ）は、第１係止片２２の先端及び第２係止片３２の先端をヤットコ５７で把持した状態を示す概略図である。図７（ｂ）は、ヤットコ５７を用いて係止爪３３を係止孔２３から外した状態を示す概略図である。   FIG. 7A is a schematic view showing a state in which the leading end of the first locking piece 22 and the leading end of the second locking piece 32 are gripped by the Yatco 57. FIG. 7B is a schematic view showing a state in which the locking claw 33 is removed from the locking hole 23 using the Yattco 57.

ヤットコ５７により第１係止片２２の先端と第２係止片３２の先端とを把持し、第１係止片２２の先端を支点にヤットコ５７を時計回りの方向へ回動させるだけで係止爪３３が係止孔２３から外れ、配電線用絶縁カバー１を配電線５１から取外すことができる。このとき第１係止片２２及び第２係止片３２は、互いの先端が略同一の高さなのでヤットコ５７による把持が容易である。なおヤットコ５７を用いる場合は、第１係止片２２の先端部２４を把持して引っ張り、係止爪３３を係止孔２３から外してもよい。   The end of the first engaging piece 22 and the end of the second engaging piece 32 are gripped by the YATCO 57, and only the YATCO 57 is rotated in the clockwise direction with the end of the first engaging piece 22 as a fulcrum. The pawl 33 is removed from the locking hole 23, and the distribution line insulating cover 1 can be removed from the distribution line 51. At this time, since the first locking piece 22 and the second locking piece 32 have substantially the same height, the gripping by the Yatco 57 is easy. In the case where the YATCO 57 is used, the front end 24 of the first locking piece 22 may be grasped and pulled, and the locking claw 33 may be removed from the locking hole 23.

このように本実施形態の配電線用絶縁カバー１は、間接活線工具を用いて配電線５１から容易に取外すことができる。   Thus, the insulating cover 1 for distribution lines of this embodiment can be easily removed from the distribution line 51 using an indirect hot wire tool.

以上のように本発明の第１実施形態の配電線用絶縁カバー１は、係止爪３３を係止孔２３に係止させるので、装着時にはしっかりと固定される。さらに係止爪３３が係止孔２３に係止したことが分かり易いので、配電線用絶縁カバー装着後の出来上がりを確認し易い。また配電線用絶縁カバー１を配電線５１から取外すときには、ほぼ垂直の状態で間接活線工具を操作することができ、操作自体も簡単なので、低位置からの間接活線工具を使用した着脱作業が容易である。   As described above, the distribution line insulating cover 1 according to the first embodiment of the present invention locks the locking claw 33 in the locking hole 23, and is thus firmly fixed when mounted. Furthermore, since it is easy to understand that the locking claw 33 is locked in the locking hole 23, it is easy to confirm the completion after the distribution line insulating cover is mounted. In addition, when removing the insulation cover 1 for the distribution line from the distribution line 51, the indirect hot wire tool can be operated in a substantially vertical state, and the operation itself is simple, so that the attaching / detaching work using the indirect hot wire tool from a low position is possible. Is easy.

図８は、本発明の第２実施形態の配電線用絶縁カバー２の断面図である。図１の第１実施形態の配電線用絶縁カバー１と同一の構成には同一の符号を付して説明を省略する。第２実施形態の配電線用絶縁カバー２は、第１実施形態の配電線用絶縁カバー１と基本的構成は同じであるが、係止爪４２の向きが異なる。   FIG. 8 is a cross-sectional view of the insulating cover 2 for distribution lines according to the second embodiment of the present invention. The same components as those of the distribution line insulating cover 1 of the first embodiment shown in FIG. The distribution line insulation cover 2 of the second embodiment has the same basic configuration as the distribution line insulation cover 1 of the first embodiment, but the direction of the locking claws 42 is different.

第２実施形態の配電線用絶縁カバー２の係止爪４２は、左側カバー部材１２の第２係止片４１の内側に設けられている。また、右側カバー部材１１及び左側カバー部材１２は、下部１５、１９がそのまま延長する形で底部２８、２９を形成しており、第１実施形態の右側カバー部材１１及び左側カバー部材１２のように水平方向に配置された底部１６、２０を有していない。また底部２８、２９の先端が下端部２１、３１となる。なお係止爪４２のその他の形成要領は、第１実施形態の配電線用絶縁カバー１の係止爪３３と同様である。   The locking claw 42 of the distribution line insulating cover 2 of the second embodiment is provided inside the second locking piece 41 of the left cover member 12. Further, the right cover member 11 and the left cover member 12 form bottom portions 28 and 29 in such a manner that the lower portions 15 and 19 extend as they are, like the right cover member 11 and the left cover member 12 of the first embodiment. It does not have the bottom parts 16 and 20 arranged in the horizontal direction. The tips of the bottom portions 28 and 29 become the lower end portions 21 and 31. In addition, the other formation point of the latching claw 42 is the same as that of the latching claw 33 of the insulating cover 1 for power distribution lines of 1st Embodiment.

第２実施形態の配電線用絶縁カバー２は、第１実施形態の配電線用絶縁カバー１と同様の方法で配電線５１に装着され、装着後は、左側カバー部材１２の下部１９の内側への弾性力により係止爪４２と係止孔２３とを係止させる方向に力が加わる。このため第１実施形態の配電線用絶縁カバー１のようにストッパーとして機能する水平方向に配置された底部１６、２０を設けることなく、第１係止片２２と第２係止片４１とをそれぞれ右側カバー部材１１及び左側カバー部材１２の中央部１４、１８に対して４５°の角度を有した状態で互いに直交させるとともに、しっかりと係止させることができる。   The distribution line insulation cover 2 of the second embodiment is attached to the distribution line 51 in the same manner as the distribution line insulation cover 1 of the first embodiment, and after the attachment, to the inside of the lower portion 19 of the left cover member 12. The force is applied in the direction in which the locking claw 42 and the locking hole 23 are locked by the elastic force. For this reason, the first locking piece 22 and the second locking piece 41 are provided without providing the bottom portions 16 and 20 arranged in the horizontal direction that function as stoppers like the distribution line insulating cover 1 of the first embodiment. Each of the right cover member 11 and the left cover member 12 can be made to be orthogonal to each other in a state of having an angle of 45 ° with respect to the central portions 14 and 18 and firmly locked.

配電線用絶縁カバー２を配電線５１から取外すときは、ヤットコ５７により第１係止片２２の先端と第２係止片４１の先端とを把持するだけで係止爪４２を係止孔２３から外すことができる。またバインド打ち器５５を使用する場合は、第２係止片４１の工具引掛孔３５にフック５６を引掛けて第２係止片４１を下方へ引っ張ると係止爪４２を係止孔２３から外すことができる。   When the insulation cover 2 for distribution lines is removed from the distribution line 51, the engagement claw 42 is engaged with the engagement holes 23 simply by gripping the distal end of the first engagement piece 22 and the distal end of the second engagement piece 41 with the Yatsuko 57. Can be removed. Further, when the bind hammer 55 is used, when the hook 56 is hooked on the tool hooking hole 35 of the second locking piece 41 and the second locking piece 41 is pulled downward, the locking claw 42 is moved from the locking hole 23. Can be removed.

このように第２実施形態の配電線用絶縁カバー２を用いると、右側カバー部材１１及び左側カバー部材１２に水平方向に配置された底部１６、２０を形成する必要がなく、取外方法も第１実施形態の配電線用絶縁カバー１に比べて多少、容易である。一方、左側カバー部材１２の下部１９の内側への弾性力に比べて左側カバー部材１２の下部１９及び第２係止片４１の自重が大きい場合には、係止爪４２が係止孔２３から自然に外れてしまう恐れがある。このため装着時に左側カバー部材１２の内側への弾性力が確実に自重よりも大きくなるように製造する必要がある。なお第２実施形態の配電線用絶縁カバー２においても右側カバー部材１１及び左側カバー部材１２に水平方向に配置された底部１６、２０を設けてもよい。   Thus, when the insulating cover 2 for distribution lines of 2nd Embodiment is used, it is not necessary to form the bottom parts 16 and 20 arrange | positioned at the horizontal direction in the right side cover member 11 and the left side cover member 12, and the removal method is also 1st. It is somewhat easier than the insulating cover 1 for distribution lines of one embodiment. On the other hand, when the weight of the lower portion 19 of the left cover member 12 and the second locking piece 41 is larger than the elastic force to the inside of the lower portion 19 of the left cover member 12, the locking claw 42 extends from the locking hole 23. There is a risk that it will come off naturally. For this reason, it is necessary to manufacture so that the elastic force to the inside of the left cover member 12 is surely greater than its own weight when mounted. Note that the right and left cover members 11 and 12 may also be provided with bottom portions 16 and 20 arranged in the horizontal direction in the insulating cover 2 for power distribution lines of the second embodiment.

図９は、本発明の第３実施形態の配電線用絶縁カバー３の概略図である。なお図９（ａ）は、本発明の第３実施形態の配電線用絶縁カバー３の概略図であり、図９（ｂ）は、図９（ａ）の配電線用絶縁カバー３の第１係止片４３の拡大図である。   FIG. 9 is a schematic view of the distribution line insulating cover 3 according to the third embodiment of the present invention. 9A is a schematic diagram of the distribution line insulation cover 3 according to the third embodiment of the present invention, and FIG. 9B is a first view of the distribution line insulation cover 3 of FIG. 9A. 4 is an enlarged view of a locking piece 43. FIG.

図１の第１実施形態の配電線用絶縁カバー１と同一の構成には同一の符号を付して説明を省略する。第３実施形態の配電線用絶縁カバー３は、第１実施形態の配電線用絶縁カバー１と基本的構成は同じであるが、第１係止片４３の先端から係止孔２３にかけて第２係止片３２の先端部３４が通過可能な溝４４が設けられている。   The same components as those of the distribution line insulating cover 1 of the first embodiment shown in FIG. The distribution line insulation cover 3 according to the third embodiment has the same basic configuration as the distribution line insulation cover 1 according to the first embodiment, but the second structure extends from the tip of the first engagement piece 43 to the engagement hole 23. A groove 44 through which the tip 34 of the locking piece 32 can pass is provided.

右側カバー部材１１の第１係止片４３には、先端から係止孔２３にかけて一定幅の溝４４が設けられている。溝４４の幅は、左側カバー部材１２の第２係止片３２の先端部３４の幅よりも広く、係止爪３３の係止部３６の幅よりも狭い。また第１係止片４３の工具引掛孔２５は、溝４４の脇に設けられている。   The first locking piece 43 of the right cover member 11 is provided with a groove 44 having a constant width from the tip to the locking hole 23. The width of the groove 44 is wider than the width of the distal end portion 34 of the second locking piece 32 of the left cover member 12 and narrower than the width of the locking portion 36 of the locking claw 33. The tool hooking hole 25 of the first locking piece 43 is provided on the side of the groove 44.

また左側カバー部材１２の下部１９及び第２係止片３２は、右側カバー部材１１の下部１５と同様、中央部１９に対して４５°内側に傾いている。   Further, the lower portion 19 and the second locking piece 32 of the left cover member 12 are inclined 45 ° inward with respect to the central portion 19, similarly to the lower portion 15 of the right cover member 11.

第３実施形態の配電線用絶縁カバー３は、右側カバー部材１１及び左側カバー部材１２を閉じるように回動させると、第２係止片３２の先端部３４が第１係止片２１の溝４４から突出する。バインド打ち器５５のフック５６を第２係止片３２の工具引掛孔３５に引掛け、又はヤットコ５７で第２係止片３２の先端を把持し、第２係止片３２の先端部３４を溝４４に通しながら第２係止片３２を引っ張ることで、係止爪３３を係止孔２３に係止させることができる。   When the insulation cover 3 for distribution lines of 3rd Embodiment is rotated so that the right side cover member 11 and the left side cover member 12 may be closed, the front-end | tip part 34 of the 2nd locking piece 32 is a groove | channel of the 1st locking piece 21. Protrude from 44. The hook 56 of the bind hammer 55 is hooked on the tool hooking hole 35 of the second locking piece 32, or the tip of the second locking piece 32 is gripped by the Yatco 57, and the tip 34 of the second locking piece 32 is moved. By pulling the second locking piece 32 while passing through the groove 44, the locking claw 33 can be locked in the locking hole 23.

第３実施形態の配電線用絶縁カバー３を用いると、左側カバー部材１２の下部１９及び第２係止片３２の内側への傾斜角度の自由度が高くなる。また第３実施形態の配電線用絶縁カバー３は、経年変化により配電線用絶縁カバー３が変形し、右側カバー部材１１の下部１５及び第１係止片４３又は左側カバー部材１２の下部１９及び第２係止片３２の内側への傾斜角度が変化しても、変形前と同様の方法で着脱させることができる。   If the insulating cover 3 for distribution lines of 3rd Embodiment is used, the freedom degree of the inclination angle to the inner side of the lower part 19 of the left side cover member 12 and the 2nd locking piece 32 will become high. Further, the distribution line insulation cover 3 of the third embodiment is deformed due to secular change, and the lower part 15 of the right cover member 11 and the first locking piece 43 or the lower part 19 of the left cover member 12 and Even if the inclination angle to the inside of the second locking piece 32 changes, it can be attached and detached in the same manner as before the deformation.

図１０は、本発明の第４実施形態の配電線用絶縁カバー４の断面図である。図１の第１実施形態の配電線用絶縁カバー１と同一の構成には同一の符号を付して説明を省略する。第４実施形態の配電線用絶縁カバー４は、第１実施形態の配電線用絶縁カバー１と基本的構成は同じであるが、係止孔６２及び係止爪６４の形成要領が異なる。   FIG. 10 is a sectional view of the insulating cover 4 for distribution lines according to the fourth embodiment of the present invention. The same components as those of the distribution line insulating cover 1 of the first embodiment shown in FIG. The distribution line insulation cover 4 according to the fourth embodiment has the same basic configuration as the distribution line insulation cover 1 according to the first embodiment, but differs in the formation procedure of the locking holes 62 and the locking claws 64.

第４実施形態の配電線用絶縁カバー４の右側カバー部材１１の下部１５及び第１係止片６１及び左側カバー部材１２の下部１９及び第２係止片６３は、それぞれ中央部１４、１８に対して内側に４５°傾いている。   The lower part 15 and the first locking piece 61 of the right cover member 11 of the insulating cover 4 for power distribution lines of the fourth embodiment, and the lower part 19 and the second locking piece 63 of the left cover member 12 are located at the center parts 14 and 18, respectively. It is inclined 45 ° inward.

第４実施形態の配電線用絶縁カバー４の係止孔６２は、右側カバー部材１１及び左側カバー部材１２が閉じるように回動したときに第２係止片６３の先端が係止孔６２を通過するように、第１実施形態の配電線用絶縁カバー１の係止孔２３に比較して大きく、かつ、より先端に設けられている。   When the right cover member 11 and the left cover member 12 are rotated so that the right cover member 11 and the left cover member 12 are closed, the distal end of the second engagement piece 63 has the engagement hole 62 in the engagement hole 62 of the distribution line insulating cover 4 of the fourth embodiment. It is larger than the locking hole 23 of the distribution line insulating cover 1 of the first embodiment and is provided at the tip so as to pass.

係止爪６４の形状は、係止孔６２の大きさ及び穿設位置に合わせて、係止部６５の高さが係止孔６２に係止可能に決められている。   The shape of the locking claw 64 is determined so that the height of the locking portion 65 can be locked to the locking hole 62 according to the size and the drilling position of the locking hole 62.

第４実施形態の配電線用絶縁カバー４は、第１実施形態の配電線用絶縁カバー１と同様の方法で配電線５１に着脱される。   The distribution line insulation cover 4 of the fourth embodiment is attached to and detached from the distribution line 51 in the same manner as the distribution line insulation cover 1 of the first embodiment.

第４実施形態の配電線用絶縁カバー４のように、係止孔の大きさ、配置及び係止爪の形状を決めることで、左側カバー部材１２の下部１９及び第２係止片６３の傾斜角度を調節することなく、右側カバー部材１１及び左側カバー部材１２が閉じるように回動したときに第２係止片６３の先端が係止孔６２を通過可能であり、かつ、係止時に第１係止片６１及び第２係止片６３がそれぞれ中央部１４、１８に対して内側に４５°傾き、互いに直交させることができる。   Like the insulating cover 4 for power distribution lines of the fourth embodiment, the inclination of the lower portion 19 of the left cover member 12 and the second locking piece 63 is determined by determining the size, arrangement, and shape of the locking claw of the locking hole. The tip of the second locking piece 63 can pass through the locking hole 62 when the right cover member 11 and the left cover member 12 are rotated so as to be closed without adjusting the angle, and the The first locking piece 61 and the second locking piece 63 can be inclined by 45 ° inward with respect to the central portions 14 and 18 and can be orthogonal to each other.

以上、第１から第４実施形態の配電線用絶縁カバーを用いて、本発明の配電線用絶縁カバーを説明したが、本発明の配電線用絶縁カバーは、上記実施形態に限定されるものではなく、要旨を変更しない範囲で変形して使用することができる。第１実施形態の配電線用絶縁カバー１では、第１係止片２２を右側カバー部材１１に、第２係止片３２を左側カバー部材１２に設けたが、第１係止片２２を左側カバー部材１２に、第２係止片３２を右側カバー部材１１に設けてもよい。   As mentioned above, although the insulation cover for distribution lines of this invention was demonstrated using the insulation cover for distribution lines of 1st to 4th embodiment, the insulation cover for distribution lines of this invention is limited to the said embodiment. Instead, it can be used by being modified without changing the gist. In the insulating cover 1 for the distribution line of the first embodiment, the first locking piece 22 is provided on the right cover member 11 and the second locking piece 32 is provided on the left cover member 12, but the first locking piece 22 is provided on the left side. The cover member 12 may be provided with the second locking piece 32 on the right cover member 11.

第１係止片２２と第２係止片３２とは、係止したときにそれぞれのカバー部材の中央部１４、１８に対して内側に４５°傾斜して互いに直交しているが、傾斜角度は、厳密に４５°である必要はない。互いにしっかりと係止され、かつ、低位置から間接活線工具を用いての配電線５１への着脱作業が容易となる傾斜角度で係止されていればよい。   When the first locking piece 22 and the second locking piece 32 are locked, the first locking piece 22 and the second locking piece 32 are inclined at 45 ° inward with respect to the central portions 14 and 18 of the respective cover members and are orthogonal to each other. Need not be exactly 45 °. What is necessary is just to be latched by the inclination angle which makes it easy to mutually attach and detach to the distribution line 51 using an indirect hot wire tool from the low position firmly.

また第１から第４実施形態では、間接活線工具を用いて配電線用絶縁カバーを着脱したが、手で直接着脱する用途を除外するものではない。なお上記実施形態に示す配電線用絶縁カバーは、分岐スリーブカバー、引留クランプカバー、ジャンパースリーブカバーなど種々の絶縁カバーに適用可能である。   In the first to fourth embodiments, the distribution line insulating cover is attached and detached using an indirect hot wire tool, but this does not exclude the use of attaching and detaching directly by hand. In addition, the insulation cover for distribution lines shown to the said embodiment is applicable to various insulation covers, such as a branch sleeve cover, a retention clamp cover, and a jumper sleeve cover.
