Description

本発明は、例えば、架空敷設されるケーブル類の敷設作業等の際に用いられるケーブル類用工具装置に関する。 The present invention relates to a cable tool device that is used, for example, in laying work of cables to be laid overhead.

例えば、通信用の光ファイバケーブル等を電柱間に架空敷設する際には、敷設作業の簡便化のために、図８に示すような、ケーブルにケーブルを支持するための支持線が一体的に形成された、いわゆる自己支持型の架空光ファイバケーブル１００が用いられる場合がある。図８に示すように、架空光ファイバケーブル１００は、光ファイバ心線１０２とテンションメンバ１０３が外被１０４で被覆されたケーブル部１０６と、支持線１０７を外被１０８で被覆して形成された支持線部１０９と、が平行に配置された状態で、それぞれの外被１０４、１０８を肉厚の薄いノッチ部１１０を介して一体的に形成されている。架空光ファイバケーブル１００は、ノッチ部１１０からケーブル部１０６と支持線部１０９とに切断分離されるようになっている。図９に示すように、架空光ファイバケーブル１００を電柱２００に支持させる際には、まず、架空光ファイバケーブル１００の電柱に支持させる中間部分の支持線部１０９とケーブル部１０６とがノッチ部１１０から分離される。ケーブル部と分離した支持線部１０９の中間部を切断し、その切断端部に電柱２００に支持線を支持させるための引留め金具１２０が取り付けられる。支持線部１０９の切断端部に引留め金具１２０を取り付ける際には、支持線部と引留め金具との連結部分の滑りを防止するために支持線部１０９の外被１０８を剥ぎ取って支持線を露出した状態で接続されている。 For example, when an optical fiber cable or the like for communication is laid overhead between utility poles, a support line for supporting the cable is integrally formed on the cable as shown in FIG. A so-called self-supporting aerial optical fiber cable 100 formed may be used. As shown in FIG. 8, the aerial optical fiber cable 100 is formed by covering the optical fiber core wire 102 and the tension member 103 with the jacket 104 and the support wire 107 with the jacket 108. In a state where the support line portion 109 is arranged in parallel, the respective jackets 104 and 108 are integrally formed through a thin notch portion 110. The aerial optical fiber cable 100 is cut and separated from the notch portion 110 into a cable portion 106 and a support wire portion 109. As shown in FIG. 9, when the overhead optical fiber cable 100 is supported by the utility pole 200, first, the support line portion 109 and the cable portion 106 of the intermediate portion supported by the utility pole of the overhead optical fiber cable 100 are notched portions 110. Separated from. An intermediate portion of the support wire portion 109 separated from the cable portion is cut, and a retaining bracket 120 for supporting the support wire on the utility pole 200 is attached to the cut end portion. When attaching the retaining bracket 120 to the cut end portion of the support line portion 109, the outer cover 108 of the support line portion 109 is peeled off and supported in order to prevent the connecting portion between the support line portion and the retention bracket from slipping. Connected with exposed wires.

従来では、上記のような支持線部１０９とケーブル部１０６とを分離させる作業や支持線部１０９の外被１０８を剥ぎ取る作業では、例えば、カッターナイフが用いられていた。支持線部１０９とケーブル部１０６とをノッチ部１１０から分離させる際には、カッターナイフの刃をノッチ部１１０に当てながらノッチ部の長手方向に沿って引いて切断分離していた。また、支持線部１０９の外被１０８を剥ぎ取る作業は、カッターナイフで支持線１０７周りの外被１０８を削ぎとるようにして支持線を露出させるものであった。 Conventionally, for example, a cutter knife has been used in the operation of separating the support wire portion 109 and the cable portion 106 as described above and the operation of peeling off the outer sheath 108 of the support wire portion 109. When the support wire portion 109 and the cable portion 106 are separated from the notch portion 110, the blade is cut and separated along the longitudinal direction of the notch portion while the blade of the cutter knife is applied to the notch portion 110. Further, the work of peeling off the outer cover 108 of the support line portion 109 is to expose the support line by scraping the outer cover 108 around the support line 107 with a cutter knife.

一方、特開平１１−７８４１号公報には、ケーブルとケーブル支持線との切り裂きを容易にすることを目的とした自己支持型ケーブルが提案されている。特開平１１−７８４１号公報の自己支持型ケーブルでは、ケーブル１と、ケーブル支持線２との間に形成された合成樹脂製の首部３の内部に２本の切り裂き紐４、４’が予め埋設されて設けられている。ケーブル１とケーブル支持線２とを分離する際には、首部３の側面３ａから少し切り裂いて、その部分に埋設された切り裂き紐を切断して切り裂き紐の端部を取り出し、該端部を把持して切り裂き紐を引くことにより、切り裂き紐４が首部の側面３ａを切り裂くようになっている。この切り裂き紐による首部側面の切り裂きを首部３の左右両側面側３ａ、３ｂからそれぞれ行ってケーブルとケーブル支持線とを分離するものであった。
特開平１１−７８４１号公報 On the other hand, Japanese Patent Application Laid-Open No. 11-7841 proposes a self-supporting cable for the purpose of facilitating the tearing of the cable and the cable support line. In the self-supporting cable disclosed in Japanese Patent Application Laid-Open No. 11-7841, two tear strings 4, 4 ′ are embedded in advance in a synthetic resin neck 3 formed between the cable 1 and the cable support wire 2. Has been provided. When separating the cable 1 and the cable support line 2 from the side surface 3a of the neck 3, the cable 3 is cut slightly, the tear string embedded in that part is cut, the end of the tear string is taken out, and the end is gripped. By pulling the tear string, the tear string 4 tears the side surface 3a of the neck. The neck side surface is cut by the tear string from the left and right side surfaces 3a and 3b of the neck 3 to separate the cable and the cable support line.
JP-A-11-7841

しかしながら、従来のように、カッターナイフを用いて支持線部とケーブル部とを分離させる場合には、架空光ファイバケーブルの敷設作業は高い位置での作業で不安定なバケット等の上での作業であるとともに、架空光ファイバケーブル自体も不安定な状態であり、作業性が悪いものであった。しかも、人の手でカッターナイフを引く作業であるから、安定かつ正確にノッチ部に沿ってカッターナイフを引くことが困難で、カッターナイフの刃がノッチ部からずれてケーブルを損傷する危険性が高かった。カッターナイフを用いて支持線部の外被を剥ぎ取る際にも同様に、作業性が悪く、安定かつ正確にカッターナイフの刃を当てることが困難で、カッターナイフで外被を削ぎ落とす際に誤ってケーブル部を損傷する恐れが高かった。光ファイバケーブルは一部でも損傷されると利用できなくなってしまうので、新たなケーブルが必要となり、ケーブルの敷設にかかる費用、労力、時間等に多大な損失が発生しやすいという問題があった。 However, when using a cutter knife to separate the support line part and cable part as in the past, the laying work of the aerial optical fiber cable is a work on an unstable bucket etc. at a high position. At the same time, the aerial optical fiber cable itself was unstable, and the workability was poor. Moreover, it is difficult to pull the cutter knife along the notch part stably and accurately because it is a work to pull the cutter knife by human hand, and there is a risk that the blade of the cutter knife may be displaced from the notch part and damage the cable. it was high. Similarly, when using a cutter knife to peel off the outer cover of the support line, workability is poor and it is difficult to apply the blade of the cutter knife stably and accurately. There was a high risk of accidentally damaging the cable. If any part of the optical fiber cable is damaged, it cannot be used. Therefore, a new cable is required, and there is a problem that a great loss is likely to occur in the cost, labor, time, etc. for laying the cable.

一方、特開平１１−７８４１号公報の自己支持型ケーブルにおいては、首部に埋設された切り裂き紐を切断して切り裂き紐の端部を取り出すために、カッターナイフを用いて首部の側面からある程度切り裂く必要があった。特に、首部の切り裂き紐を切断する際には切り裂き紐に交差するようにカッターナイフの刃を当てる必要もあった。したがって、上記従来の場合と同様に、高い位置での不安定なバケット等上での作業で、作業性が悪く、安定かつ正確なカッターナイフの操作が困難であるから、カッターナイフの刃が首部からずれてケーブル部を損傷する恐れが高かった。さらに、自己支持型ケーブルの左右両側面それぞれから引き裂き紐による引き裂き操作を行うので、２回同じ工程を繰り返す必要があり、作業が煩雑なものであった。また、支持線部の外被を剥ぎ取る際には上記従来と同様にカッターナイフを用いた作業となり、外被を削ぎ落とす際に誤ってケーブル部を損傷する恐れが高く、費用等に多大な損失が生じやすいという問題があった。 On the other hand, in the self-supporting cable disclosed in Japanese Patent Application Laid-Open No. 11-7841, it is necessary to cut to some extent from the side of the neck using a cutter knife in order to cut the tear string embedded in the neck and take out the end of the tear string was there. In particular, when cutting the tear string at the neck, it was necessary to apply the blade of the cutter knife so as to cross the tear string. Therefore, as in the conventional case described above, work on an unstable bucket or the like at a high position is inferior in workability, and it is difficult to operate a stable and accurate cutter knife. There was a high risk of damaging the cable part. Furthermore, since the tearing operation with the tear string is performed from both the left and right side surfaces of the self-supporting cable, the same process needs to be repeated twice, and the work is complicated. Also, when stripping the outer sheath of the support wire portion, it is an operation using a cutter knife as in the conventional case, and there is a high risk of damaging the cable portion when scraping off the outer sheath, which is very expensive. There was a problem that loss was likely to occur.

本発明は、上記従来の課題に鑑みてなされたものであり、その目的は、ケーブルを損傷することがないように正確かつスムーズに支持線部とケーブル部とを分離することができるケーブル類用工具装置を提供することである。さらに、他の目的は、ケーブル類の外被を簡単かつスムーズに剥ぎ取ることができるケーブル類用工具装置を提供することである。 The present invention has been made in view of the above-described conventional problems, and an object thereof is for cables that can separate a support wire portion and a cable portion accurately and smoothly so as not to damage the cable. It is to provide a tool device. Another object of the present invention is to provide a cable tool device capable of easily and smoothly stripping the jacket of cables.

The opening / closing configuration of the operation unit and the opening / closing operation unit may be arbitrary. For example, the opening / closing operation unit is opened / closed via a pivot by sliding the paired handles so as to be separated from each other and opening / closing the opening / closing operation unit. Any other configuration may be used. The operation of moving the opening / closing action part along the longitudinal direction of the cables is configured to move the operator in any direction, such as a pushing operation, a pulling operation, a side-sliding operation, etc. of the tool device. Also good. Moreover, the guide part may be comprised by assembling a plate-shaped piece, a bowl-shaped piece, a block piece, etc., for example.

また、開閉作用部１４を閉じてケーブル類の長手方向に沿って開閉作用部１４を移動させるにあたり、ガイド部２２は、ケーブル本体の断面周囲を取り囲むように形成されることとしてもよい。ガイド部は、ケーブル類のある程度の長さにわたって全周面側に当接または近接するように取り囲むと好適である。 Further, in closing the opening / closing action part 14 and moving the opening / closing action part 14 along the longitudinal direction of the cables, the guide part 22 may be formed so as to surround the periphery of the cross section of the cable body . It is preferable that the guide portion is surrounded so as to be in contact with or close to the entire circumferential surface side over a certain length of cables.

また、開閉作用部１４は、中間にケーブル類（１００）を挟むように開閉する一対の作用片体２０ａ、２０ｂを有し、一対の作用片体２０ａ、２０ｂの閉鎖時にそれぞれの作用片体２０ａ、２０ｂの要素（２６、２８）が咬み合い状に組み合わされてコ字長枠状の受部３２を形成することとしてもよい。下側の作用片体２０ｂにはガイド部２２の一部を成す受部３０が、上側の作用片体２０ａには切刃部２４が設けられたこととしてもよい。 Moreover, the opening / closing action part 14 has a pair of action piece bodies 20a, 20b that open and close so as to sandwich the cables (100) in the middle, and each action piece body 20a is closed when the pair of action piece bodies 20a, 20b are closed. , 20b (26, 28) may be combined to form a U-shaped long frame-shaped receiving portion 32. The lower working piece body 20b may be provided with a receiving portion 30 forming a part of the guide portion 22, and the upper working piece body 20a may be provided with a cutting edge portion 24.

また、上側作用片体２０ａは、ケーブル類（１００）の支持線部１０９とケーブル部１０６との境界線（１１０）に対応して配置された切刃部２４を有し、該切刃部２４と平行に配置されて一対の作用片体２０ａ、２０ｂの閉鎖時にケーブル類（１００）の外側面に当接又は近接してガイド部２２の一部を成すように突設された組み合わせ側片２８を備えたこととしてもよい。 The upper operating piece body 20a has a cutting edge 24 disposed corresponding to the cables (100) of the support line portions 109 and the boundary line between the cable portion 106 (110), cutting edge portion 24 The combination side piece 28 that is arranged in parallel with the pair of action pieces 20a, 20b and protrudes so as to form a part of the guide portion 22 in contact with or close to the outer surface of the cables (100) when the pair of action pieces 20a, 20b is closed. it is also possible with a.

また、ケーブル部を分離させた支持線部１０９の端部を遊挿状に挿通させ該支持線部１０９の外径よりやや大きな内径を有する挿通孔３８と、挿通孔３８に位置合わせして固定された刃状縁部４０と、を含み、挿通孔３８及び刃状縁部４０に挿通された支持線部１０９に対して相対的に挿通孔及び刃状縁部を傾けて支持線部の長手方向に移動させることで支持線部１０９の外被１０８を削ぎ取りさせるように、挿通孔及び刃状縁部が、支持線部１０９の挿通時に挿通孔及び刃状縁部に遊びをもって通される大きさに設定されていることとしてもよい。外被剥離部の配置位置は任意でよいが、開閉作用部の分離部の近傍であって、互いに邪魔しない位置に配置されると、装置全体がコンパクトに設計でき、操作性がよい。 Further, the end portion of the support wire portion 109 from which the cable portion is separated is inserted in a loosely inserted manner, and the insertion hole 38 having an inner diameter slightly larger than the outer diameter of the support wire portion 109 is aligned and fixed to the insertion hole 38. A blade edge 40, and the insertion hole 38 and the support line portion 109 inserted through the blade edge 40 are inclined relative to the insertion hole 38 and the blade edge 40 to extend the length of the support line portion. The insertion hole and the blade-like edge are passed through the insertion hole and the blade-like edge with play when the support wire 109 is inserted so that the outer sheath 108 of the support wire 109 is scraped off by moving in the direction. It may be set to a size . The arrangement position of the outer cover peeling portion may be arbitrary, but if it is arranged in the vicinity of the separation portion of the opening / closing action portion and not interfering with each other, the entire apparatus can be designed compactly and the operability is good.

本発明のケーブル類用工具装置によれば、支持線部とケーブル部とが外被を介して一体的に形成されたケーブル類用の工具装置であって、操作部と、操作部の開閉操作で開閉する開閉作用部と、を含み、開閉作用部は、閉操作でケーブル類を支持しつつケーブル類の長手方向に沿って移動させることにより支持線部とケーブル部とを分離させる分離部を有する構成であるから、操作部を介して開閉作用部を閉操作してケーブル類に沿って移動させるだけの簡単な操作だけでよく、操作性が良好である。したがって、例えば、ケーブル類を架空敷設する際などに、バケット上等の不安定な場所でケーブル類自体が不安定な状態であっても、一人の作業者だけで安定した分離操作を行うことができ、正確かつスムーズに支持線部とケーブル部とを分離させることができる。 According to the cable tool device of the present invention, the support wire portion and the cable portion are a tool device for cables integrally formed through a jacket, and the operation portion and the opening / closing operation of the operation portion are performed. An opening / closing action portion that opens and closes at a position, and the opening / closing action portion includes a separation portion that separates the support wire portion and the cable portion by moving along the longitudinal direction of the cables while supporting the cables by a closing operation. Since it is the structure which has, it is only necessary to perform a simple operation of closing the opening / closing action part via the operation part and moving it along the cables, and the operability is good. Therefore, for example, when cables are laid overhead, even if the cables themselves are unstable in an unstable place such as on a bucket, a single operator can perform a stable separation operation. And the support wire portion and the cable portion can be separated accurately and smoothly.

また、分離部は、ケーブル類の長手方向に沿って開閉作用部を移動させるにあたり、ケーブル類の幅方向へのズレ移動を規制しつつケーブル類を収容するガイド部と、ガイド部内に収容されるケーブル類の支持線部とケーブル部との境界線に対向するように刃先が向けられて配置された切刃部と、を含む構成とすることにより、ケーブル類を支持しながらケーブル類の長手方向に沿って移動させることにより支持線部とケーブル部とを分離させる分離部の構成を具体的に実現できる。同時に、ガイド部によりケーブル類の幅方向へのズレ移動を規制できるので、切刃部が正確にケーブル類の境界線に沿って当たりながら移動でき、ケーブル部を損傷させることなく正確に境界線から分離させることができる。 Further, the separation unit is accommodated in the guide unit that accommodates the cables while restricting the displacement movement of the cables in the width direction when moving the opening / closing action unit along the longitudinal direction of the cables. The longitudinal direction of the cables while supporting the cables by including a cutting blade portion with the cutting edge directed to face the boundary line between the support wire portion of the cables and the cable portion. The structure of the separation part that separates the support line part and the cable part can be specifically realized. At the same time, displacement of the cables in the width direction can be controlled by the guide section, so the cutting edge can move while hitting the boundary line of the cable accurately, and from the boundary line without damaging the cable section. Can be separated.

また、開閉作用部を閉じてケーブル類の長手方向に沿って開閉作用部を移動させるにあたり、ガイド部は、ケーブル類の断面周囲を取り囲むように形成される構成とすることにより、簡単な構成で、ケーブル類の幅方向を含むケーブル類の長手方向に交差するいずれの方向へのズレ移動を確実に規制することができ、切刃部を正確に支持線部とケーブル部との境界線に当てることができる。 Further, when the opening / closing action part is closed and the opening / closing action part is moved along the longitudinal direction of the cables, the guide part has a simple structure by being formed so as to surround the periphery of the cross-section of the cables. The displacement movement in any direction that intersects the longitudinal direction of the cables, including the width direction of the cables, can be reliably controlled, and the cutting edge portion is accurately applied to the boundary line between the support wire portion and the cable portion. be able to.

また、開閉作用部は、中間にケーブル類を挟むように開閉する一対の作用片体を有し、下側の作用片体にはガイド部の一部を成す受部が、上側の作用片体には切刃部が設けられた構成とすることにより、下側の作用体に設けられた受部にケーブル類を下側から支持させた状態で作用片体を閉鎖することにより、ケーブル類をガイド部へ収容を簡単な操作で確実に行えるとともに、作用片体の閉操作に伴って受部に支持させたケーブル類に上側から切刃部を当てることができるので、操作性が良好である。 The opening / closing action part has a pair of action pieces that open and close so as to sandwich the cables between them, and the lower action piece has a receiving part that forms a part of the guide part as an upper action piece. In the configuration in which the cutting blade portion is provided, the operation piece body is closed while the cables are supported from the lower side by the receiving portion provided in the lower operation body, so that the cables are The guide part can be reliably accommodated by a simple operation, and the cutting blade part can be applied from above to the cables supported by the receiving part in accordance with the closing operation of the action piece body, so that the operability is good. .

また、受部は端面視コ字枠を形成する構成とすることにより、受部にケーブル類を収容操作が行いやすいとともに、受部に支持させたケーブル類が脱落することなく安定した支持状態を保持でき、ガイド部内へのケーブルの収容及びケーブル類の境界線へ切刃部を当てる操作を作用片体の閉操作を良好に行える。特に、受部のコ字枠がケーブル類の外側面に当接または近接するように形成されると受部内に収容させたケーブル類が作用片体を開いた状態のままでも横ずれせず、開閉作用部を閉操作して切刃部を支持線部とケーブル部の境界線に当てさせる際に、正確な操作が行える。 In addition, the receiving part is configured to form a U-shaped frame when viewed from the end, so that the cable can be easily accommodated in the receiving part, and the cable supported by the receiving part can be stably supported without falling off. The operation piece can be satisfactorily closed by the operation of accommodating the cable in the guide portion and applying the cutting edge portion to the boundary line of the cables. In particular, when the U-shaped frame of the receiving part is formed so as to come into contact with or close to the outer surface of the cables, the cables housed in the receiving part do not shift laterally even when the working piece is open, and can be opened and closed. When the operating portion is closed and the cutting blade portion is brought into contact with the boundary line between the support wire portion and the cable portion, an accurate operation can be performed.

また、一対の作用片体の閉鎖時にそれぞれの作用片体の要素が咬み合い状に組み合わされてコ字長枠状の受部を形成する構成とすることにより、作用片体を開いた状態でケーブル類を配置させやすく操作性が良好であるとともに、作用片体の閉鎖時にはコ字状長枠を形成してある程度の長さにわたってケーブル類の横ズレを規制し、切刃部を正確にケーブル類の境界線に当てながら開閉作用部を移動させることができる。よって、ケーブル部を損傷させることなく正確かつスムーズに支持線部とケーブル部の分離作業を行える。 In addition, when the pair of action pieces are closed, the elements of the action pieces are combined in an interlocking manner to form a U-shaped long frame-shaped receiving portion, so that the action pieces are opened. Cables are easy to place and have good operability. When the action piece is closed, a U-shaped long frame is formed to regulate the lateral displacement of the cables over a certain length, and the cutting blade is accurately cabled. It is possible to move the opening / closing action part while hitting the boundary line. Therefore, it is possible to separate the support wire portion and the cable portion accurately and smoothly without damaging the cable portion.

また、上側作用片体は、ケーブル類の支持線部とケーブル部との境界線に対応して配置された切刃部と、該切刃部と平行に配置されて一対の作用片体の閉鎖時にケーブル類の外側面に当接又は近接してガイド部の一部を成す組み合わせ側片が突設されている構成であるから、例えば、切刃部と組み合わせ側片との平行離隔間に支持線部等を収容しつつ、ケーブル類の外側面に沿って移動しながら切刃部を当てることにより、切刃部に対するケーブル類の横ズレを規制して切刃部を正確にケーブル類の境界線に当てながら移動させることができる。 Further, the upper action piece is formed by a cutting edge portion corresponding to the boundary line between the support line portion of the cables and the cable portion, and a pair of action piece bodies closed in parallel with the cutting edge portion. Since the combination side piece forming a part of the guide portion is sometimes in contact with or close to the outer surface of the cables, for example, it is supported between the parallel separation between the cutting edge portion and the combination side piece. By holding the cutting blade while moving along the outer surface of the cables while accommodating the wire, etc., the lateral displacement of the cables with respect to the cutting blade is regulated, so that the cutting blade is accurately bounded by the cables. You can move while hitting the line.

また、操作部及び開閉作用部は、枢軸を介して接続され、操作部の握持離開操作により開閉作用部を開閉動作させるように設けられた構成とすることにより、簡単な構造で、操作性がよく、操作部からの操作を確実に開閉作用部側に伝達できる操作部及び開閉作用部の構成を具体的に実現できる。 In addition, the operation part and the opening / closing action part are connected via a pivot and are configured to open and close the opening / closing action part by holding and releasing the operation part. Therefore, it is possible to specifically realize the configuration of the operation part and the opening / closing action part that can reliably transmit the operation from the operation part to the opening / closing action part side.

また、ケーブル部を分離させた支持線部の端部を遊挿状に挿通させ該支持線部の外径よりやや大きな内径を有する挿通孔と、挿通孔のいずれかの孔口に形成され挿通させた支持線部の長手方向に移動させることにより支持線部の外被を削ぎ取りさせる刃状縁部と、を含む外被剥離部が設けられた構成とすることにより、支持線部を挿通孔に一旦挿通させて逆方向に支持線部に沿って移動させるだけでよく、操作性が良好であるとともに、外被剥離部が挿通孔で支持線部に案内されながら刃状縁部が外被に当たるので安定した操作が行える。よって、ケーブル部を損傷させることがなく、支持線部の外被を簡単かつスムーズに剥ぎ取ることができる。 Further, the end portion of the support wire portion from which the cable portion is separated is inserted in a loosely-inserted manner, and an insertion hole having an inner diameter slightly larger than the outer diameter of the support wire portion is formed in any one of the insertion holes. The support line portion is inserted by adopting a configuration in which an outer edge peeling portion including a blade-like edge portion that scrapes off the outer cover of the support line portion by moving the support line portion in the longitudinal direction is provided. It only needs to be inserted once into the hole and moved along the support line part in the opposite direction, and the operability is good and the outer edge of the outer edge peels off while being guided by the support line part through the insertion hole. Stable operation can be performed because it hits the cover. Therefore, the outer cover of the support line portion can be easily and smoothly peeled off without damaging the cable portion.

次に、本実施形態にかかるケーブル類用工具装置の作用を説明する。例えば、図８、図９に示すように、支持線部１０９とケーブル部１０６とが一体となった架空光ファイバケーブル１００を電柱２００に支持させる際に用いられる。図９に示すように、架空光ファイバケーブル１００を電柱２００に支持させる際には、まず、架空光ファイバケーブル１００を支持線部１０９とケーブル部１０６とに分離させる。この分離作業では、操作部１２を操作して開閉作用部１４を開き受部３０に架空光ファイバケーブル１００を配置させる。受部３０は、端面視コ字枠を形成するように設けられており、長尺の架空光ファイバケーブル１００の中間部分に配置させやすいとともに、受部３０に配置させたケーブル１００の横ズレを防止しつつ収容状態を維持する。操作部１２を握持して開閉作用部１４を閉操作すると、切刃部２４が支持線部とケーブル部の境界線であるノッチ部に当たりつつ、架空光ファイバケーブル１００が作用片体の突設片２６〜２９によってその断面周囲を取り囲まれながらガイド部２２に収容される。この閉操作の際、受部３０がケーブル１００の横ズレを防止しているので切刃部２４は確実にノッチ部に当てることとなる。そして、操作部１２を握持しつつ開閉作用部１４を閉じた状態で操作部側へ引き動作して開閉作用部を架空光ファイバケーブル１００の長手方向に沿って移動させることにより、支持線部とケーブル部とが分離される。この引き動作の際には、ガイド部２２により、架空光ファイバケーブルの幅方向へのズレ移動を規制して正確に切刃部が架空光ファイバケーブル１００の境界線を切断分離する。特に、図に示すように、開閉作用部１４を閉じた際に組み合わせ構成されるコ字長枠状の受枠３２が架空光ファイバケーブルの外側面に当接し、引き動作する際の架空光ファイバケーブル１００の横ズレを規制して切刃部２４が当たる部分では常に架空光ファイバケーブルは切刃部の切断方向に沿って移動しながら切断分離される。これにより、例えば、高い位置でのバケット上等の不安定な場所でも、支持線部を支持しながら簡単な操作で分離作業が行えるとともに、正確かつスムーズに支持線部とケーブル部とを分離することができる。 Next, the operation of the cable tool device according to the present embodiment will be described. For example, as shown in FIGS. 8 and 9, the power pole 200 is used to support an aerial optical fiber cable 100 in which a support wire portion 109 and a cable portion 106 are integrated. As shown in FIG. 9, when the aerial optical fiber cable 100 is supported by the utility pole 200, first, the aerial optical fiber cable 100 is separated into the support line portion 109 and the cable portion 106. In this separation work, the operating unit 12 is operated to open the opening / closing action unit 14 and to place the overhead optical fiber cable 100 in the receiving unit 30. The receiving part 30 is provided so as to form a U-shaped frame when viewed from the end, and is easy to place in the middle part of the long aerial optical fiber cable 100, and the lateral displacement of the cable 100 placed in the receiving part 30 is reduced. Maintain the containment state while preventing. When the operation section 12 is gripped and the opening / closing operation section 14 is closed, the cutting edge section 24 hits the notch section that is the boundary line between the support line section and the cable section, while the aerial optical fiber cable 100 projects the working piece. The section 26 to 29 is accommodated in the guide portion 22 while being surrounded by the cross section. During the closing operation, the receiving portion 30 prevents the lateral displacement of the cable 100, so that the cutting blade portion 24 is surely applied to the notch portion. Then, by holding the operating unit 12 and pulling it toward the operating unit with the opening / closing operation unit 14 closed, the opening / closing operation unit is moved along the longitudinal direction of the aerial optical fiber cable 100, thereby supporting line unit And the cable part are separated. At the time of this pulling operation, the guide portion 22 regulates the displacement movement of the overhead optical fiber cable in the width direction, and the cutting blade portion accurately cuts and separates the boundary line of the overhead optical fiber cable 100. In particular, as shown in the figure, the overhead optical fiber cable when the U-shaped long frame-shaped receiving frame 32 configured to be combined when the opening / closing action portion 14 is closed comes into contact with the outer surface of the overhead optical fiber cable and pulls. The horizontal optical fiber cable is always cut and separated while moving along the cutting direction of the cutting edge portion at the portion where the cutting edge portion 24 abuts by restricting the lateral displacement of 100. As a result, for example, even in an unstable place such as on a bucket at a high position, separation work can be performed with a simple operation while supporting the support line part, and the support line part and the cable part are separated accurately and smoothly. be able to.

支持線部をケーブル部と分離した後に、工具装置の切断部４２を利用して支持線部は中間位置で切断される。図７に示すように、支持線部１０９の外被を剥ぎ取る際には、外被剥離部３４の挿通孔３８に支持線部１０９の切断端部から挿通させる。刃状縁部４０を支持線部の外被１０８に当たるように工具装置を傾けながら支持線部の長手方向に沿って引き動作させて、支持線部の外被の一部を削ぎ取る。この操作を例えば、４、５回繰り返して、支持線部の外被を剥離させる。これにより、簡単な操作で、ケーブル部を損傷させることなく、確実に支持線部の外被を剥ぎ取ることができる。また、架空光ファイバケーブル１００を電柱に支持させた後に、接地するためのアース線１２２を引き留め金具１２０部分で接続する際には、図３に示すように、圧着部４６を介して銅スリーブ５２をアース線１２２に圧着接続させる。なお、本実施形態では、分離部１６、切断部４２、外被剥離部３４等が、開閉作用部周りに集約して設けられているので、バケット等上での、支持線部とケーブル部との分離、支持線部の切断、支持線部の外被剥ぎ取り等を含む一連の作業を、工具を持ち換えることなくスムーズに行え、利便性が高い。 After separating the support wire portion from the cable portion, the support wire portion is cut at an intermediate position using the cutting portion 42 of the tool device. As shown in FIG. 7, when peeling off the outer cover of the support wire portion 109, the support wire portion 109 is inserted through the insertion hole 38 of the outer cover peeling portion 34 from the cut end portion of the support wire portion 109. The tool device is tilted and moved along the longitudinal direction of the support line portion so that the blade-like edge portion 40 abuts the outer cover 108 of the support line portion, and a part of the outer cover of the support line portion is scraped off. This operation is repeated, for example, four or five times to peel off the outer cover of the support line portion. Thereby, it is possible to surely peel off the outer cover of the support line portion without damaging the cable portion by a simple operation. Further, when the grounding wire 122 for grounding is connected to the retaining bracket 120 after the aerial optical fiber cable 100 is supported by the utility pole, the copper sleeve 52 is interposed via the crimping portion 46 as shown in FIG. Is crimped to the ground wire 122. In the present embodiment, the separation part 16, the cutting part 42, the jacket peeling part 34 and the like are provided around the opening / closing action part, so that the support line part and the cable part on the bucket or the like are provided. A series of operations including separation, cutting of the support line part, and stripping of the support line part can be performed smoothly without changing the tool, which is highly convenient.
