Description

本発明は、碍子に仮に取付ける碍子の付属具に関し、特に、バインド線の不具合等で電線が碍子から脱落した場合に、早急に送電(仮送電)ができるようにする電線預け用キャップに関する。   TECHNICAL FIELD The present invention relates to an insulator accessory that is temporarily attached to an insulator, and more particularly, to an electric wire depositing cap that can quickly transmit power (temporary power transmission) when an electric wire is dropped from the insulator due to a defect in a binding wire or the like.

従来、電線を架設する電柱などには、電線を支持する碍子及びこの碍子を固定する金属製の腕金が取付けられている。電柱における電線の引き通し箇所では、バインド線の不具合等で電線が碍子から脱落し、腕金に接触する場合がある。バインド線は、一般に金属線に絶縁材料を被覆したものであり、風雨や直射日光にさらされることから、絶縁材料が摩耗や損傷を起こしやすい。また、強風等により電線が揺動を繰り返すと、バインド線が電線に食い込み、絶縁材料が電線と擦れて摩耗し、電線を介してバインド線が充電される恐れがある。このようにバインド線が充電された電線が、碍子から脱落して腕金に接触した場合、電線と腕金との間に地絡事故を引き起こすという危険性もある。   2. Description of the Related Art Conventionally, an insulator that supports an electric wire and a metal arm metal that fixes the insulator are attached to a utility pole for installing the electric wire. At the place where the electric wire is passed through the utility pole, the electric wire may fall off the insulator due to a defect of the binding wire, etc., and may contact the arm metal. The bind wire is generally a metal wire coated with an insulating material, and is exposed to wind and rain or direct sunlight, so that the insulating material is likely to be worn or damaged. Further, when the electric wire repeatedly swings due to strong winds or the like, the bind wire may bite into the electric wire, and the insulating material may be worn by rubbing against the electric wire, so that the bind wire may be charged via the electric wire. Thus, when the electric wire with which the bind line was charged fell out of an insulator and contacted a bracelet, there also exists a danger that a ground fault will be caused between an electric wire and a bracelet.

このように、バインド線が巻き付いた状態の電線が碍子から脱落して腕金に接触している場合、地絡事故を防ぐために、早急に電線を腕金から離し、電線を元どおりに碍子に取り付けた状態にする必要がある。また、地絡事故の心配がなければ、電線をなるべく停電させずに活線状態のまま元どおりに碍子に取り付けた状態にすることが望まれる。活線作業ではホットスティック等を利用する間接活線作業用工具が用いられる(間接活線工法)。   In this way, when the wire with the bind wire wrapped around is dropped from the insulator and is in contact with the armrest, in order to prevent a ground fault, immediately remove the wire from the armrest and return the wire to the insulator as before. It needs to be attached. Moreover, if there is no worry about a ground fault, it is desirable that the electric wire be kept attached to the insulator as it is in a live line state without causing a power failure as much as possible. In the live line work, an indirect live line work tool using a hot stick or the like is used (indirect live line method).

関連する技術としては、特許文献1の電線架設部材の取付具を参照する。電線を支持させるピン碍子や引留碍子などの架設部材が損傷した場合に、早急にその電線を架設し直すことを可能にするものである。腕金に空いている貫通穴などを必要とすることなく、架設部材の連結部をその腕金に取り付けた取付部の被連結部に連結させることができ、例えば、倒木などにより既存の腕金の被連結部が再利用不能に損傷している場合でも、その腕金を交換することなく、健全な被連結部をその腕金に早期に取り付けて架設部材を連結することができる。したがって、損傷した架設部材の連結されている腕金を交換することなく、追加した健全な架設部材に電線を架設支持させることができ、早急に送電を再開して復旧作業を短時間に完了することができる。   As a related technique, the fixture of the electric wire construction member of patent document 1 is referred. When a construction member such as a pin insulator or a retaining insulator for supporting an electric wire is damaged, the electric wire can be immediately re-installed. The connecting part of the erection member can be connected to the connected part of the mounting part attached to the arm metal without the need for a through hole or the like vacant in the arm metal. Even when the connected portion is damaged in a non-reusable manner, the erected member can be quickly attached to the arm metal and the construction member can be connected without replacing the arm metal. Therefore, the electric wire can be installed and supported on the added healthy construction member without exchanging the brace connected to the damaged construction member, and the power transmission is resumed quickly to complete the restoration work in a short time. be able to.

特開2008−236963号公報JP 2008-236963 A

特許文献1の電線架設部材の取付具は、腕金に被せてボルト締めする構成が示されており、相応の工数がかかる。また、碍子から脱落したバインド線が巻き付いたままの電線の場合、まず、電線に巻き付いたバインド線を取り外す作業を考え、バインド線の取り外しに時間を要する懸念がある。活線作業では間接活線工法が必須であり、電線やバインド線の扱いはより困難で相当の時間がかかる。   The structure of the electric wire erection member of Patent Document 1 is shown in a configuration in which a bolt is put on an arm and bolted, and a corresponding man-hour is required. Further, in the case of an electric wire on which the bind wire that has fallen from the insulator is still wound, there is a concern that it takes time to remove the bind wire, considering an operation of removing the bind wire wound around the electric wire. In the hot wire work, the indirect hot wire method is indispensable, and the handling of electric wires and bind wires is more difficult and takes a considerable amount of time.

本発明は、上記事情を考慮してなされたものであり、その目的は、碍子から脱落したバインド線が巻き付いたままの電線を、仮送電(または仮復旧)でもよいから、なるべく短時間で安全に送電できるようにするための電線預け用キャップを提供することにある。   The present invention has been made in consideration of the above circumstances, and its purpose is to secure the power as short as possible because the electric wire with the bind wire dropped from the insulator may be temporarily transmitted (or temporarily recovered). An object of the present invention is to provide a cap for keeping an electric wire so that power can be transmitted to a cable.

(1)本発明の電線預け用キャップに係る一実施態様は、開口部を有し、碍子の一部を内部に侵入させることのできる弾性変形可能な取付け部と、該取付け部の内部の表面を前記碍子に密着させる締付け手段と、前記取付け部の外部で開閉機構が組み込まれた取り囲み部材を有する電線の確保部と、前記取付け部の外部の表面に設けられる一つ以上の把持用部分と、を備える。   (1) One embodiment of the electric wire depositing cap according to the present invention has an opening, an elastically deformable attachment that allows a part of the insulator to enter inside, and an inner surface of the attachment Tightening means for tightly contacting the insulator, an electric wire securing portion having an enclosing member in which an opening / closing mechanism is incorporated outside the attachment portion, and one or more gripping portions provided on the outer surface of the attachment portion; .

(1)の電線預け用キャップの構成によれば、取付け部の開口部が碍子の一部、好ましくは碍子の上部に被せられ、取付け部が締付け手段によって碍子に密着固定される。取付け部を、碍子に被せたり、締付け固定したりする際には間接活線工法が用いられる。したがって、把持用部分は、間接活線作業用工具で挟持するのに利便性が高いところに設けられることが好ましい。電線の確保部では、開閉機構を介して取り囲み部材に囲まれる領域内に電線を移動させて、電線の周辺を取り囲む状態にする。取り囲み部材は、上記開口部ほど弾性変形の必要はなく、ある程度の剛性を有して、かつ電線が勢いよく接触しても電線の被覆が損傷しないような部材で構成される。また、取り囲み部材は、バインド線が巻き付いたままの電線も取り囲める領域を有することが好ましい。これにより、碍子から脱落したバインド線が巻き付いたままの電線を、碍子に簡易に固定される電線預け用キャップに仮に預け、早急に安全な仮送電(または仮復旧)の状態にできる。   According to the configuration of the wire depositing cap of (1), the opening portion of the attachment portion is covered with a part of the insulator, preferably the upper portion of the insulator, and the attachment portion is tightly fixed to the insulator by the fastening means. An indirect hot wire method is used when the mounting portion is covered with an insulator or is fastened and fixed. Therefore, it is preferable that the gripping portion is provided in a place that is highly convenient for being held by the indirect hot wire working tool. In the wire securing portion, the wire is moved into a region surrounded by the surrounding member via the opening / closing mechanism so as to surround the periphery of the wire. The surrounding member is not required to be elastically deformed as the opening portion is, and has a certain degree of rigidity, and is configured by a member that does not damage the covering of the electric wire even when the electric wire contacts with force. Moreover, it is preferable that an enclosing member has an area | region which can also enclose the electric wire with the bind wire wound around. As a result, the electric wire with the bind wire that has fallen off the insulator is temporarily deposited in the electric wire depositing cap that is simply fixed to the insulator, so that a safe provisional power transmission (or provisional restoration) can be made immediately.

(2)本発明の電線預け用キャップに係る一実施態様に関し、上記(1)において、締付け手段は、取付け部の外部の表面から取付け部を締め付けるバンド部材を含む。バンド部材は、好ましくはケーブルタイ(結束バンド)の利用が考えられる。取付け部の外部周辺にケーブルタイを設置して、取付け部を外部周囲から締め付ける。これにより、碍子への安定した固定が簡易に達成できる。また、碍子への固定が不要になった場合はケーブルタイを外すか切断すればよい。これにより、碍子への着脱が簡単にできる電線預け用キャップが提供できる。   (2) With respect to one embodiment of the wire depositing cap according to the present invention, in the above (1), the tightening means includes a band member for tightening the mounting portion from the outer surface of the mounting portion. The band member is preferably a cable tie (tie band). Install a cable tie around the outside of the mounting area, and tighten the mounting area from the outside. Thereby, the stable fixation to an insulator can be achieved easily. If it is no longer necessary to fix the insulator, the cable tie may be removed or cut. As a result, it is possible to provide a wire depositing cap that can be easily attached to and detached from the insulator.

(3)本発明の電線預け用キャップに係る一実施態様に関し、上記(1)において、電線の確保部における開閉機構は、取り囲み部材に囲まれる領域の内側に移動する方向に開き、所定の外力が加えられないときは、取り囲み部材として機能する閉じた状態を維持するゲートを含む。つまり、ゲートを介して取り囲み部材に囲まれる領域内に押し入れられた電線は、電線の確保部として取り囲み部材に取り囲まれたままの状態を維持する。取り囲み部材は、上記したように、バインド線が巻き付いたままの電線も取り囲める領域を有することが望ましい。これにより、碍子から脱落したバインド線が巻き付いたままの電線を、取り囲み部材で確保することによって碍子上に仮に預けられる形態をとることができる。   (3) With respect to one embodiment of the electric wire depositing cap according to the present invention, in (1) above, the opening / closing mechanism in the wire securing portion opens in the direction of moving to the inside of the region surrounded by the surrounding member, and a predetermined external force When is not added, it includes a gate that remains closed to function as an enclosing member. That is, the electric wire pushed into the region surrounded by the surrounding member via the gate maintains the state of being surrounded by the surrounding member as a securing portion of the electric wire. As described above, the surrounding member desirably has a region that can also surround the electric wire on which the bind wire is wound. Accordingly, it is possible to take a form in which the electric wire with the bind wire that has fallen from the insulator is still wrapped around the insulator by securing the electric wire with the surrounding member.

(4)本発明の電線預け用キャップに係る一実施態様に関し、上記(1)において、電線の確保部における開閉機構は、取り囲み部材に囲まれる領域の外側に開き、取り囲み部材として機能する閉じた状態ではロック可能なゲートを含む。つまり、ゲートを開いて取り囲み部材に囲まれる領域内に電線が移動され、ゲートを閉じてロックする。これにより、電線は、電線の確保部として取り囲み部材に取り囲まれたままの状態を維持する。取り囲み部材は、上記したように、バインド線が巻き付いたままの電線も取り囲める領域を有することが望ましい。これにより、碍子から脱落したバインド線が巻き付いたままの電線を、取り囲み部材で確保することによって碍子上に仮に預けられる形態をとることができる。   (4) With respect to one embodiment of the wire depositing cap according to the present invention, in (1) above, the opening / closing mechanism in the wire securing portion opens outside the region surrounded by the surrounding member and functions as the surrounding member. The state includes a lockable gate. That is, the electric wire is moved into a region surrounded by the surrounding member by opening the gate, and the gate is closed and locked. Thereby, an electric wire maintains the state still surrounded by the surrounding member as a securing part of an electric wire. As described above, the surrounding member desirably has a region that can also surround the electric wire on which the bind wire is wound. Accordingly, it is possible to take a form in which the electric wire with the bind wire that has fallen from the insulator is still wrapped around the insulator by securing the electric wire with the surrounding member.

本発明によれば、碍子から、バインド線が巻き付いたままの電線が脱落したとしても、巻き付いたバインド線の処置は後回しにして安全な仮送電(または仮復旧)を最優先させる電線預け用キャップを提供することができる。   According to the present invention, even if an electric wire with a bind wire wound off from an insulator, a wire depositing cap that places the highest priority on safe temporary power transmission (or temporary restoration) by postponing the treatment of the wound bind wire later. Can be provided.

図1は、本発明の一実施形態に係る電線預け用キャップの外観図である。電線預け用キャップ100は、碍子への取付け部10と、取付け部10の締付け手段としてのバンド部材20と、取付け部10の外部で電線の周辺を取り囲む電線の確保部30と、取り扱いに便利な把持用部分40と、を含んで構成される。以下、各構成を詳細に説明する。   FIG. 1 is an external view of a wire depositing cap according to an embodiment of the present invention. The wire depositing cap 100 includes a mounting portion 10 for the insulator, a band member 20 as a tightening means for the mounting portion 10, a wire securing portion 30 surrounding the periphery of the wire outside the mounting portion 10, and convenient for handling. And a gripping portion 40. Hereinafter, each configuration will be described in detail.

取付け部10は、耐候性、絶縁性に優れた可撓性を有する合成樹脂により形成され、弾性変形可能な開口部101を有して碍子の一部を内部に侵入させることができる。上記合成樹脂材料としては、難燃性のポリエチレン樹脂、シリコーン、EVA樹脂やEPゴム等の高分子材料が考えられる。   The attachment portion 10 is formed of a flexible synthetic resin having excellent weather resistance and insulation, and has an opening 101 that can be elastically deformed so that a part of the insulator can enter inside. Examples of the synthetic resin material include polymer materials such as flame retardant polyethylene resin, silicone, EVA resin, and EP rubber.

バンド部材20は、取付け部10の外部の表面から取付け部10を締め付けるものであって、この実施形態ではケーブルタイ(結束バンド)201を用いている。すなわち、取付け部10の外部周辺にケーブルタイ201を設置して締め付けることにより、取付け部10の内部の表面を碍子に密着させる。   The band member 20 tightens the attachment portion 10 from the outer surface of the attachment portion 10, and in this embodiment, a cable tie (binding band) 201 is used. That is, by installing and tightening the cable tie 201 around the outside of the mounting portion 10, the inner surface of the mounting portion 10 is brought into close contact with the insulator.

ケーブルタイ201は、取扱い上、ヘッド部201hにテール部201tを通してリング状にされたものを用いることが好ましい。ケーブルタイ201は、バンド部の一部を予め取付け部10の外部の表面に付帯させ、締め付け時に締め付けるようにしてもよいし、別個に後から取付け部10の周囲に配置させて、締め付け時に締め付けるようにしてもよい。   The cable tie 201 is preferably used in a ring shape through the tail portion 201t in the head portion 201h for handling. The cable tie 201 may be preliminarily attached to the outer surface of the mounting portion 10 at a part of the band portion and tightened at the time of tightening, or may be separately arranged around the mounting portion 10 and tightened at the time of tightening. You may do it.

電線預け用キャップ100が不要になったとき、ケーブルタイ201を切断することによって、電線預け用キャップ100は、碍子から容易に取り外すことができる。また、ケーブルタイ201においては、取り外し可能で繰り返し使えるタイプもある。このような、切断しなくても取り外しが可能なケーブルタイ201を用いてもよい。   When the wire depositing cap 100 is no longer needed, the wire depositing cap 100 can be easily removed from the insulator by cutting the cable tie 201. In addition, there is a cable tie 201 that can be removed and used repeatedly. A cable tie 201 that can be removed without being cut may be used.

電線の確保部30は、取付け部10の外部で開閉機構としてのゲート301が組み込まれた取り囲み部材302を有する。取り囲み部材302は、上記開口部101ほど弾性変形の必要はなく、ある程度の剛性を有して、かつ電線が勢いよく接触しても電線の被覆が損傷しないような部材で構成される。この実施形態では、取り囲み部材302は、ゲート301も含めて取付け部10と同じ材料で外表面が形成され、内部に剛性の高い芯材(絶縁性の合成樹脂等)303が内蔵されている。   The wire securing portion 30 includes a surrounding member 302 in which a gate 301 as an opening / closing mechanism is incorporated outside the attachment portion 10. The surrounding member 302 does not need to be elastically deformed as much as the opening 101, has a certain degree of rigidity, and is configured by a member that does not damage the coating of the electric wire even if the electric wire contacts with force. In this embodiment, the surrounding member 302 has an outer surface made of the same material as that of the mounting portion 10 including the gate 301, and a highly rigid core material (insulating synthetic resin or the like) 303 is built therein.

上記電線の確保部30は、電線WR(横断面で示される)を、取り囲み部材302に囲まれる領域外から領域内にゲート301を介して移動させ、電線WRの周辺を取り囲む。ゲート301は、その基端側の支軸AXに図示しないトーションばね等が組み込まれており、矢印D1に示されるように、取り囲み部材302に囲まれる領域の内側に移動する方向に開き、かつ所定の外力が加えられないときは取り囲み部材として機能する閉じた状態を維持する。この実施形態では、支軸AX側とは反対側のゲート301の先端が取り囲み部材302の溝切り終端の頂壁に当接することで、ゲート301が閉じた状態を維持する。これにより、取り囲み部材302に囲まれる領域内に押し入れられた電線WRは、電線の確保部30として取り囲み部材302に取り囲まれたままの状態を維持する。   The wire securing unit 30 moves the wire WR (shown in a cross section) from the outside of the region surrounded by the surrounding member 302 into the region through the gate 301 and surrounds the periphery of the wire WR. The gate 301 has a torsion spring (not shown) incorporated in the support shaft AX on the base end side thereof, and as shown by an arrow D1, opens in a direction to move to the inside of the region surrounded by the surrounding member 302, and is predetermined. When the external force is not applied, the closed state that functions as the surrounding member is maintained. In this embodiment, the tip of the gate 301 on the side opposite to the support shaft AX side contacts the top wall of the grooving end of the surrounding member 302, so that the gate 301 is kept closed. Thereby, the electric wire WR pushed into the area surrounded by the surrounding member 302 maintains the state of being surrounded by the surrounding member 302 as the wire securing portion 30.

また、取り囲み部材302に囲まれる領域は、ゲート301の開閉の寸法も含めて、バインド線が巻き付いたままの電線でも余裕をもって取り囲める領域を有している。これにより、碍子から脱落したバインド線が巻き付いたままの電線WRを、ゲート301を介して取り囲み部材302に囲まれる領域内へ押し入れることができる。これにより、電線WRは、バインド線が巻き付いたまま碍子上に仮に預けられる形態をとることができる。   In addition, the region surrounded by the surrounding member 302 has a region that can surround the electric wire with the binding wire wound around, including the opening and closing dimensions of the gate 301. As a result, the electric wire WR with the bind wire that has fallen off the insulator can be pushed into the region surrounded by the surrounding member 302 via the gate 301. Thereby, the electric wire WR can take the form temporarily deposited on an insulator with the bind wire wound around.

把持用部分40は、取付け部10の外部の表面に突出して設けられるもので、電線預け用キャップ100の取り扱いのため、複数あってもよい。すなわち、取付け部10を碍子に被せたり、バンド部材20で締付け固定したりする際には間接活線工法が用いられる。したがって、把持用部分40は、間接活線作業用工具で挟持するのに利便性が高いところに設けられることが好ましい。この実施形態における把持用部分40は、取付け部10の外表面の延出部分で構成され、開口部101よりも電線の確保部30に近い位置に設けられている。   The gripping portion 40 is provided so as to protrude from the outer surface of the mounting portion 10, and a plurality of gripping portions 40 may be provided for handling the wire depositing cap 100. That is, an indirect hot wire method is used when the mounting portion 10 is covered with an insulator or is fastened and fixed by the band member 20. Therefore, it is preferable that the gripping portion 40 is provided in a place that is highly convenient for being held by the indirect hot-wire work tool. The gripping portion 40 in this embodiment is constituted by an extended portion of the outer surface of the mounting portion 10 and is provided at a position closer to the wire securing portion 30 than the opening portion 101.

上記構成の電線預け用キャップによれば、碍子から脱落したバインド線が巻き付いたままの電線を、碍子に簡易に固定可能な電線預け用キャップに仮に預け、早急に安全な仮送電(または仮復旧)の状態にできる。   According to the wire storage cap configured as described above, the wire with the bind wire that has fallen off the insulator is temporarily stored in the wire storage cap that can be easily fixed to the insulator, so that safe temporary power transmission (or temporary recovery) can be performed immediately. ) State.

図2〜図4は、それぞれ図1の電線預け用キャップの使用例を順次示す外観図である。図2を参照すると、電柱における電線の引き通し箇所の碍子ISLにバインド線BWで固定されていた電線WRが脱落し、バインド線BWが巻き付いたまま、電柱の腕金CAに接触している。このような状況は、強風、バインド線の不具合や経年劣化等が原因で起こり得、前述したように、電線WRを介してバインド線BWが充電されていると、電線WRと腕金CAとの間に地絡事故を引き起こす危険性がある。よって、地絡事故を防ぐために、早急に電線を腕金から離し、電線を碍子に取り付けた状態に戻す作業が必要である。この作業は間接活線工法を採用し、ホットスティック等を利用する間接活線作業用工具が用いられる。   2 to 4 are external views sequentially showing examples of use of the wire depositing cap of FIG. Referring to FIG. 2, the electric wire WR fixed by the bind wire BW to the insulator ISL of the electric pole through which the electric wire is passed is dropped, and the bind wire BW is still in contact with the arm metal CA of the electric pole. Such a situation may occur due to strong winds, a malfunction of the bind wire, deterioration over time, etc. As described above, when the bind wire BW is charged via the wire WR, the wire WR and the arm metal CA There is a risk of causing a ground fault in between. Therefore, in order to prevent a ground fault, it is necessary to quickly remove the electric wire from the arm and return the electric wire to a state where it is attached to the insulator. This work employs an indirect hot wire method, and an indirect hot wire work tool using a hot stick or the like is used.

図3を参照すると、碍子ISLに、電線預け用キャップ100が被せられ、固定されている。例えば、図示しない間接活線作業用工具で把持用部分40を挟持するなどして、電線預け用キャップ100を移動させる。取付け部10の開口部101を碍子ISLの上部に被せることにより、取付け部10の内部に碍子ISLの一部を侵入させる。その後、ヘッド部201hにテール部201tを通してリング状にしたケーブルタイ(結束バンド)201を、間接活線作業用工具を用いて、取付け部10の周辺に配置する。テール部201tを引っ張り、取付け部10の内部の表面を碍子ISLに密着させるように締め付ける。これにより、電線預け用キャップ100が碍子ISLに固定される。   Referring to FIG. 3, an electric wire depositing cap 100 is put on the insulator ISL and fixed. For example, the wire depositing cap 100 is moved by holding the gripping portion 40 with an indirect hot wire working tool (not shown). By covering the opening 101 of the attachment portion 10 on the top of the insulator ISL, a part of the insulator ISL is caused to enter the inside of the attachment portion 10. Thereafter, a cable tie (bundling band) 201 formed in a ring shape through the tail portion 201t is arranged around the attachment portion 10 using an indirect hot wire working tool. The tail part 201t is pulled and tightened so that the inner surface of the attachment part 10 is in close contact with the insulator ISL. As a result, the wire depositing cap 100 is fixed to the insulator ISL.

図4を参照すると、電線預け用キャップ100の電線の確保部30に電線WRが確保されている。例えば、図示しない間接活線作業用工具で電線WRを掴み、ゲート301を介して取り囲み部材302に囲まれる領域内へバインド線BWが巻き付いたままの電線WRを押し入れる。これにより、電線WRは、バインド線BWが巻き付いたまま碍子上に仮に預けられる形態をとることができる。   Referring to FIG. 4, the electric wire WR is secured in the wire securing portion 30 of the wire depositing cap 100. For example, the electric wire WR is grasped by an indirect hot wire working tool (not shown), and the electric wire WR with the bind wire BW wound around is inserted into the region surrounded by the surrounding member 302 via the gate 301. Thereby, the electric wire WR can take the form temporarily deposited on an insulator with the bind wire BW wound.

上記電線預け用キャップの使用例によれば、碍子ISLから脱落したバインド線BWが巻き付いたままの電線WRを、碍子ISLに簡易に固定される電線預け用キャップ100に仮に預け、早急に安全な仮送電(または仮復旧)の状態にすることが可能である。これにより、電線WRからバインド線BWを取り外す作業や電線WRを碍子に正常に取り付ける作業等は、その後余裕をもって慎重に行うことができる。   According to the use example of the wire depositing cap, the wire WR that is still wrapped around the bind wire BW that has fallen from the insulator ISL is temporarily deposited in the wire depositing cap 100 that is simply fixed to the insulator ISL. It is possible to make a temporary power transmission (or temporary recovery) state. Thereby, the operation | work which removes the binding wire BW from the electric wire WR, the operation | work which attaches the electric wire WR normally to an insulator, etc. can be performed carefully with margin after that.

図5〜図9は、それぞれ図1の電線預け用キャップの構成の部分的な変形例を示す概観図である。図5と図6は把持用部分40の変形例、図7は、取付け部10の変形例、図8は、取付け部10と電線の確保部30の接続部分の変形例、図9は、電線の確保部30のゲート構造の変形例をそれぞれ示す。   5 to 9 are schematic views showing partial modifications of the configuration of the wire depositing cap shown in FIG. 5 and 6 are modifications of the gripping portion 40, FIG. 7 is a modification of the attachment portion 10, FIG. 8 is a modification of the connection portion between the attachment portion 10 and the wire securing portion 30, and FIG. Each modification of the gate structure of the securing portion 30 is shown.

図5を参照すると、取付け部10の外部の表面において、開口部101の縁部に、把持用部分としてフランジ状の把持用部分401が設けられている。また、図6を参照すると、取付け部10の開口部101の近傍や開口部101の近傍から離れた取付け部10の外部の表面に、図1の把持用部分40と同様形状の把持用部分402が複数(四方に)設けられている。このように、把持用部分は、間接活線作業用工具で挟持するのに便利な任意の部分に設けられてよい。   Referring to FIG. 5, a flange-like gripping portion 401 is provided as a gripping portion on the edge of the opening 101 on the outer surface of the mounting portion 10. Further, referring to FIG. 6, a gripping portion 402 having the same shape as the gripping portion 40 of FIG. 1 is formed on the surface of the mounting portion 10 in the vicinity of the opening portion 101 or on the outer surface of the mounting portion 10 away from the vicinity of the opening portion 101.

また、図5または図6の構成によれば、取付け部10の外表面から把持用部分が多く突出する形態により、取付け部10を締め付けるバンド部材20(ケーブルタイ201)のリング形状が、締め付け前において、操作を誤るなどして取付け部10から脱落させてしまうのを防ぐ利点もある。   Further, according to the configuration of FIG. 5 or FIG. 6, the ring shape of the band member 20 (cable tie 201) for tightening the mounting portion 10 is the same as that before tightening due to the form in which many gripping portions protrude from the outer surface of the mounting portion 10. In this case, there is an advantage of preventing the mounting unit 10 from dropping off due to an erroneous operation.

図7を参照すると、取付け部10の開口部101の縁部に切れ込み部102が形成されている。切れ込み部102の終端103は円形カットされており、裂け防止に効果を発揮する。このような切れ込み部102は、開口部101を碍子の上部に被せ易くする利点があり、複数設けられてもよい。   Referring to FIG. 7, a notch 102 is formed at the edge of the opening 101 of the mounting portion 10. The end 103 of the notch 102 is cut in a circular shape, and is effective in preventing tearing. Such a notch 102 has an advantage of easily covering the opening 101 on the top of the insulator, and a plurality of the notches 102 may be provided.

図8を参照すると、取付け部10と取り囲み部材302が別体となっており、樹脂性の留め具50、あるいは樹脂ネジまたは絶縁ボルト等で取付け部10と取り囲み部材302が着脱自在に結合される形態になっている。取付け部10と取り囲み部材302のうちいずれかに不具合が生じた場合、取り外して交換が可能である。また、取付け部10の開口部101(または取り囲み部材302)において、違うサイズが必要な場合、取り外して交換が可能である。   Referring to FIG. 8, the mounting portion 10 and the surrounding member 302 are separated, and the mounting portion 10 and the surrounding member 302 are detachably coupled with a resinous fastener 50, a resin screw, an insulating bolt, or the like. It is in form. If any of the attachment portion 10 and the surrounding member 302 has a problem, it can be removed and replaced. In addition, if a different size is required in the opening 101 (or the surrounding member 302) of the mounting portion 10, it can be removed and replaced.

図9を参照すると、電線の確保部30において、取り囲み部材302に組み込まれるゲート301の開閉動作が矢印D2に示すようであり、ゲート301は、取り囲み部材302で囲まれる領域の外側に開き、取り囲み部材302で囲まれる領域を作るように閉じる形態となっている。支軸AX側とは反対側のゲート301の先端が取り囲み部材302の溝切り終端の底壁に当接することで、ゲート301が閉じた状態を維持する。ゲート301の先端が当接する側の取り囲み部材302において、ネジの嵌め合い等によるゲートロック部材60が設けられている。ゲートロック部材60は、蝶ナット形状の回動式ロック部であり、つまみ部分601と、嵌め口の切欠きによるロック解除部分602とを有する。ゲートロック部材60は、例えば、絶縁性プラスチックなどの、剛性の高い絶縁性樹脂で構成されている。   Referring to FIG. 9, in the wire securing portion 30, the opening / closing operation of the gate 301 incorporated in the surrounding member 302 is as indicated by an arrow D <b> 2, and the gate 301 opens outside the area surrounded by the surrounding member 302. It is a form which closes so that the area | region enclosed with the member 302 may be made. The gate 301 is kept closed by the tip of the gate 301 on the side opposite to the support shaft AX being in contact with the bottom wall of the grooving end of the surrounding member 302. In the surrounding member 302 on the side where the tip of the gate 301 abuts, a gate lock member 60 is provided by screw fitting or the like. The gate lock member 60 is a wing nut-shaped rotation-type lock portion, and includes a knob portion 601 and a lock release portion 602 due to a notch in the fitting opening. The gate lock member 60 is made of, for example, a highly rigid insulating resin such as an insulating plastic.

ゲートロック部材60を回してロック解除部分602をゲート301の先端部上方に合わせれば、ゲート301はロック解除できる。ゲート301は、支軸AXを中心に回動させて、取り囲み部材302の間を開けることができる(破線参照)。図示しない電線を取り囲み部材302間に移動させた後、上がっていたゲート301を下ろして、ゲート301が閉じた状態を維持する。このように、取り囲み部材302として機能するゲート301が閉じた状態にいて、ゲートロック部材60を回してロックする(図9参照)。これにより、取り囲み部材302に囲まれる領域内に置かれた電線は、電線の確保部30として取り囲み部材302に取り囲まれたままの状態を維持する。   The gate 301 can be unlocked by turning the gate lock member 60 and aligning the unlocking portion 602 above the tip of the gate 301. The gate 301 can be rotated about the support shaft AX to open the space between the surrounding members 302 (see the broken line). After the electric wire (not shown) is moved between the surrounding members 302, the gate 301 that has been raised is lowered and the gate 301 is kept closed. In this manner, the gate 301 functioning as the surrounding member 302 is closed, and the gate lock member 60 is turned to lock (see FIG. 9). Thereby, the electric wire placed in the region surrounded by the surrounding member 302 maintains the state of being surrounded by the surrounding member 302 as the wire securing portion 30.

図9の構成によれば、ゲートロック部材60は、蝶ナット形状のつまみ部分601を有し、間接活線作業用工具で挟持し易いなど、扱いが楽である。また、つまみ部分601が両側に延出する正面と、ロック解除部分602の正面とを一致させている。これにより、ロック解除している時、つまみ部分601は、ゲート301が開く取り囲み部材302の間の領域に干渉しない。また、ゲート301は、開くときには取り囲み部材302で囲まれる領域の外側に移動する。これにより、特に取り囲み部材302に囲まれる領域内に確保した電線を、領域外に出すときの間接活線作業用工具の作業性に優れる。   According to the configuration of FIG. 9, the gate lock member 60 has a wing nut-shaped knob portion 601 and is easy to handle, such as being easily clamped with an indirect hot wire working tool. Further, the front surface where the knob portion 601 extends to both sides and the front surface of the unlocking portion 602 are made to coincide. Thereby, when the lock is released, the knob portion 601 does not interfere with the area between the surrounding members 302 where the gate 301 opens. Further, when the gate 301 is opened, the gate 301 moves outside the region surrounded by the surrounding member 302. Thereby, it is excellent in the workability | operativity of the tool for indirect hot-wire work when taking out the electric wire ensured especially in the area | region enclosed by the surrounding member 302 out of an area | region.

上記図5〜図9それぞれの変形例の少なくともいずれか一つの構成は、図1の電線預け用キャップ100の構成の対応する部分と置換えることができる。これにより、碍子から、バインド線が巻き付いたままの電線が脱落したとしても、巻き付いたバインド線の処置は後回しにして安全な仮送電(または仮復旧)を最優先できる電線預け用キャップを提供することができる。   5 to 9 can be replaced with a corresponding portion of the configuration of the wire depositing cap 100 of FIG. As a result, even if an electric wire with a bind wire wound off from an insulator, the wire binding cap that has been wound is provided later, and a cap for depositing an electric wire that can give priority to safe temporary power transmission (or temporary restoration) is provided. be able to.
