Description

本願発明は、例えば電柱間等に架設されている架空配電線の間接活線工法に関する。詳しくは、上記架空配電線の絶縁被覆部分を、その導線部分から軸方向に一定長さだけ剥離し、剥離した後の電線の被覆が路上等に落下するのを防止する被覆剥ぎコマに関する。   The present invention relates to an indirect live-line construction method for overhead distribution lines installed between, for example, utility poles. More specifically, the present invention relates to a stripping piece for peeling off the insulation coating portion of the overhead distribution line from the conductor portion by a predetermined length in the axial direction, and preventing the coating of the stripped wire from dropping on a road or the like.

従来、架空配電線の間接活線工法として、作業員が高所作業用バケットに搭乗し、絶縁操作棒(いわゆるホットスティック)等の上端に装備した切削刃を電線の中間部または端部において、その電線の周囲を周回させることにより、絶縁被覆を螺旋状に切削して剥離し、任意の長さだけ剥離する工法が採用されている。   Conventionally, as an indirect hot-line method of overhead distribution lines, a worker is mounted on a bucket for working at heights, and a cutting blade equipped at the upper end of an insulating operating rod (so-called hot stick) etc. is used at the middle or end of the wire, A method is employed in which the insulation coating is spirally cut and peeled by being wound around the electric wire, and peeled by an arbitrary length.

そして、特許文献1に示す電線被覆屑の脱落防止工具は、切断された被覆が路上に落下して通行人や車両等に当たったり、路上に散乱して汚したりするのを防止するために、剥離された被覆を巻き付けて保持する巻付棒を備えている。具体的には、この特許文献1に示す電線被覆屑の脱落防止工具は、電線の軸方向に移動しながら何度も周回しつつ、被覆を螺旋状に切削してゆき、所定の長さに剥離できるまで続けるものである。そして、螺旋状に切削された被覆は、巻付棒に送り出されて順次巻き付くので、脱落することがないのである。   Then, the tool for preventing the wire covering debris from falling off disclosed in Patent Document 1 is to prevent the cut covering from falling on the road and hitting a pedestrian or a vehicle, or being scattered and dirty on the road. A winding rod for winding and holding the peeled coating is provided. Specifically, the wire covering debris fall prevention tool disclosed in Patent Document 1 spirally cuts the covering while moving around the wire many times while moving in the axial direction of the wire, and cutting to a predetermined length. Continue until peeling is possible. Then, the spirally cut coating is sent out to the winding rod and sequentially wound, so that it does not fall off.

しかしながら、予め決められた所定の長さだけ電線の被覆を剥離したい場合、この特許文献1の電線被覆屑の脱落防止工具では、電線の軸方向に移動しながら何度も周回しなければならず、作業が面倒である。   However, when it is desired to peel off the covering of the electric wire by a predetermined length, the electric wire covering debris falling prevention tool disclosed in Patent Document 1 has to move around the electric wire many times while moving in the axial direction of the electric wire. , The work is troublesome.

そこで、決められた所定の長さだけ電線の被覆を剥離したい場合などは、電線の周囲を一度周回するだけで作業が完了すること、つまり一括で被覆剥ぎができることが望ましい。ただ、電線の周囲を一周だけ周回して被覆を剥離する場合は、剥離された被覆が環状になるので、従来の巻付棒に上手く巻きつくことができず、脱落する可能性がある。そこで、このような一括で被覆剥ぎができる工具において、剥離された被覆が脱落しないように、最適な構造を備えた被覆剥ぎ工具の開発が望まれていた。   Therefore, when it is desired to peel off the covering of the electric wire by a predetermined length, it is desirable that the work is completed only by making a round around the electric wire once, that is, it is desirable that the covering can be peeled off at once. However, when the coating is peeled around the electric wire by only one round, the peeled coating becomes annular, so that the coating cannot be wound well on the conventional winding rod and may fall off. Therefore, in such a tool capable of stripping the coating at once, there has been a demand for the development of a coating stripping tool having an optimal structure so that the stripped coating does not fall off.

特開2013−192430JP 2013-192430

よって、本願発明は、上記問題に鑑み、一括で被覆剥ぎを行う場合に、剥離された被覆が脱落しないように、最適な構造を備える被覆剥ぎコマを提供する。   Therefore, in view of the above problems, the present invention provides a coating stripping piece having an optimal structure so that the stripped coating does not fall off when the coating is stripped at once.

上記課題を解決するために、本願発明の被覆剥ぎコマは、電線の被覆を一方のコマ分割体と他方のコマ分割体とで両側から挟持し、いずれか一方のコマ分割体に装着された被覆剥取刃で前記被覆を環状に剥ぎ取る被覆剥ぎコマであって、当該被覆剥ぎコマは、外部動力により電線の軸周りに回転させるコマ駆動工具に取り付け可能であり、前記一方のコマ分割体と前記他方のコマ分割体の挟持面により、前記電線を挟持した状態で、前記被覆剥取刃は、前記電線の被覆に臨むように取り付けられており、さらに、当該被覆剥取刃の後方には、互いの間隔が、当該被覆剥取刃の幅よりも狭い2枚の保持板からなる被覆脱落防止部を備えたことを特徴とする。   In order to solve the above-mentioned problem, the coating stripping piece of the present invention sandwiches the coating of an electric wire from both sides with one piece divided body and the other piece divided body, and the covering attached to one of the piece divided bodies. A coating stripping piece that strips the coating in an annular shape with a stripping blade, the coating stripping piece can be attached to a top driving tool that rotates around the axis of the electric wire by external power, and the one piece split body In a state where the electric wire is sandwiched by the holding surface of the other frame division body, the coating stripping blade is attached so as to face the coating of the electric wire, and further, behind the coating stripping blade. And a coating separation preventing portion formed of two holding plates having a distance between each other smaller than the width of the coating stripping blade.

上記特徴によれば、被覆脱落防止部の後端側保持部と先端側保持部の間隔が、被覆剥取刃の幅よりも狭くなっているという簡単で最適な構造により、剥ぎ取られて被覆剥取刃の後方へ送り出された被覆を圧縮して、脱落しないように保持することができる。   According to the above feature, the distance between the rear end side holding portion and the front end side holding portion of the coating falling-off prevention portion is narrower than the width of the coating stripping blade. The coating delivered to the rear of the stripping blade can be compressed and held from falling off.

さらに、本願発明の被覆剥ぎコマは、前記保持板の一方は、他方の前記保持板に向けて傾斜していることを特徴とする。   Furthermore, the coating stripping piece of the present invention is characterized in that one of the holding plates is inclined toward the other holding plate.

上記特徴によれば、被覆剥取刃の後方へ順次送り出されてくる被覆を、その傾斜に沿って、徐々にスムーズに圧縮することができる。   According to the above feature, the coating sequentially sent to the rear of the coating stripping blade can be gradually and smoothly compressed along the inclination.

さらに、本願発明の被覆剥ぎコマは、前記一方のコマ分割体と前記他方のコマ分割体を互いに連結する連結部は、前記被覆剥ぎコマを前記コマ駆動工具へ取り付けるための取付部とは反対の先端側に備えられていることを特徴とする。   Further, in the coating stripping piece of the present invention, the connecting portion for connecting the one frame splitting body and the other frame splitting body to each other is opposite to a mounting portion for mounting the coating stripping piece to the frame driving tool. It is provided on the tip side.

電線の被覆を被覆剥取刃で剥離する際に、被覆剥取刃は被覆から大きな抵抗力を受けるが、上記特徴によれば、コマ分割体及びコマ分割体とが閉じた状態をより強力に維持できる。   When the sheath of the electric wire is stripped by the sheath stripping blade, the sheath stripping blade receives a large resistance from the coating. Can be maintained.

本願発明の被覆剥ぎコマによれば、一括で被覆剥ぎを行う場合に、最適な構造により、剥離された被覆が脱落しないようにできる。
According to the coating stripping piece of the present invention, when the coating stripping is performed at a time, the stripped coating can be prevented from falling off by an optimal structure.

まず、本願発明に係る被覆剥ぎコマ400を取り付けるためのコマ駆動工具100について説明するが、このコマ駆動工具100は外部動力により電線の軸周りに被覆剥ぎコマ400を回転させるものであり、コマ駆動工具100自体は既に公知のものであるので(例えば特許文献1にも開示されている)、ここでは簡単に説明する。   First, a frame driving tool 100 for mounting the coating stripping piece 400 according to the present invention will be described. The frame driving tool 100 rotates the coating stripping piece 400 around the axis of the electric wire by external power. Since the tool 100 itself is already known (for example, disclosed in Patent Document 1), it will be briefly described here.

<コマ駆動工具100について>
図1及び図2に示すように、このコマ駆動工具100は、大別して、駆動部110と、回転駆動部120と、この回転駆動部120に内蔵されているコマフォルダ130とで構成される。駆動部110は、図示しない下方の電動又は手動の正逆転可能な外部動力と連結され、その外部動力からの駆動力を上方の回転駆動部120のコマフォルダ130に伝達するものである。さらに、外部動力と連結される連結軸114が下方に設けられ、その連結軸114の中間部115は、筒状ケーシング116内に装着されたベアリング117によって回転自在に軸支されている。
<About the top drive tool 100>
As shown in FIGS. 1 and 2, the frame driving tool 100 is roughly divided into a driving unit 110, a rotation driving unit 120, and a frame folder 130 built in the rotation driving unit 120. The drive unit 110 is connected to a lower electric or manual reversible external power which is not shown and can transmit the driving force from the external power to the top folder 130 of the upper rotary drive unit 120. Further, a connection shaft 114 connected to external power is provided below, and an intermediate portion 115 of the connection shaft 114 is rotatably supported by a bearing 117 mounted in a cylindrical casing 116.

この回転駆動部120は、連結軸114からの駆動力を受けてコマフォルダ130を正逆方向に回動させるもので、上部の部分傘歯車121と下部の部分傘歯車122とを備え、それぞれの内側端部が枢支ピン123で連結されている。また、下部の部分傘歯車122は、連結軸114と連結しており、連結軸114が回転すると部分傘歯車121と部分傘歯車122は、一体となって筒状ケーシング116の内面を摺動しつつ回動することができる。さらに、それぞれの部分傘歯車121及び部分傘歯車122は、それぞれの内周面に、図3に示すコマ分割体300を取り付けるためのコマフォルダ分割体131と、図3に示すコマ分割体200を取り付けるためのコマフォルダ分割体132とを保持できるスペースを備えている。   The rotation drive unit 120 receives the driving force from the connection shaft 114 and rotates the top folder 130 in the forward and reverse directions. The rotation drive unit 120 includes an upper partial bevel gear 121 and a lower partial bevel gear 122. The inner ends are connected by pivot pins 123. Further, the lower partial bevel gear 122 is connected to the connection shaft 114, and when the connection shaft 114 rotates, the partial bevel gear 121 and the partial bevel gear 122 slide integrally on the inner surface of the cylindrical casing 116. It is possible to pivot while rotating. Further, each of the partial bevel gear 121 and the partial bevel gear 122 includes a frame folder divided body 131 for attaching the frame divided body 300 shown in FIG. 3 and a frame divided body 200 shown in FIG. A space for holding the frame folder divided body 132 for attachment is provided.

また、図2に示すように、コマフォルダ130は、コマフォルダ分割体131及びコマフォルダ分割体132から構成されており、このコマフォルダ分割体131及びコマフォルダ分割体132は、二つ割りの半円状のもので、それぞれの端部が枢支ピン123で開閉自在に枢支されている。   As shown in FIG. 2, the frame folder 130 is composed of a frame folder divided body 131 and a frame folder divided body 132. The frame folder divided body 131 and the frame folder divided body 132 are divided into two semicircles. Each end is pivotally supported by a pivot pin 123 so as to be freely opened and closed.

なお、フック140は、コマフォルダ130が正転中(図の矢印方向)に口を開かないようにするものであり、全体がコマフォルダ分割体131側のピン141に枢支され、コマフォルダ130が正転中は、コマフォルダ分割体132側のピン142に先端143が掛け止めされている。   The hook 140 prevents the top of the frame folder 130 from opening while the frame folder 130 is rotating forward (in the direction of the arrow in the figure). During forward rotation, the tip 143 is hooked on the pin 142 on the frame folder divided body 132 side.

<被覆剥ぎコマ400について>
次に、図3を参照して、本願発明の被覆剥ぎコマ400について説明する。この被覆剥ぎコマ400は、金属性のコマ分割体200とコマ分割体300とから構成されている。このコマ分割体200及びコマ分割体300は、いずれも、筒体を中央面Fを境目にして半割り状にした形状で、連結部210及び連結部310によって、互いに分離及び連結できるようになっている。
<About the stripping top 400>
Next, with reference to FIG. 3, the coating stripping piece 400 of the present invention will be described. The covering strip 400 includes a metal frame 200 and a metal frame 300. Each of the frame division body 200 and the frame division body 300 has a shape in which the cylindrical body is divided into half with the center plane F as a boundary, and can be separated and connected to each other by the connection part 210 and the connection part 310. ing.

そして、このコマ分割体200の連結部210は貫通孔を備えた筒型形状で、コマ分割体200の先端側に形成されている。一方のコマ分割体300の連結部310も、貫通孔を備えた筒型形状で、コマ分割体300の先端側に形成されている。そして、軸部材Pを、連結部210及び連結部310の両方の貫通孔に挿通させることで、コマ分割体200とコマ分割体300は互いに、軸部材Pを中心として開閉可能に連結されることになる。   The connecting portion 210 of the frame division body 200 has a cylindrical shape having a through hole, and is formed on the front end side of the frame division body 200. The connecting portion 310 of one of the frame divided bodies 300 is also formed in a cylindrical shape having a through hole, and is formed on the front end side of the frame divided body 300. Then, the frame member 200 and the frame member 300 are connected to each other so as to be openable and closable about the shaft member P by inserting the shaft member P into the through holes of both the connecting portion 210 and the connecting portion 310. become.

また、コマ分割体200及びコマ分割体300のそれぞれには、断面が半円形状の挟持面220及び挟持面320が、被覆剥ぎコマ400の先端側から後端側まで連続するように形成されている。この挟持面220及び挟持面320は、中央面Fに対して対称な形状をしているので、図3(a)に示すように、コマ分割体200とコマ分割体300とを中央面Fで互いに閉じた状態では、円筒状になる。そして、この円筒状になった挟持面220と挟持面320で、電線の周囲を囲むように挟持することができる。   Further, in each of the frame divided body 200 and the frame divided body 300, a holding surface 220 and a holding surface 320 having a semicircular cross section are formed so as to be continuous from the front end side to the rear end side of the coating stripping top 400. I have. Since the holding surfaces 220 and 320 have a symmetrical shape with respect to the center plane F, the frame division body 200 and the frame division body 300 are divided by the center plane F as shown in FIG. When they are closed, they are cylindrical. Then, the cylindrical holding surface 220 and holding surface 320 can be held so as to surround the electric wire.

また、コマ分割体200及びコマ分割体300のそれぞれの後端側には、フランジ部230及びフランジ部330が形成され、そのフランジ部230及びフランジ部330のそれぞれには貫通孔231及び貫通孔331が形成されている。   Further, a flange portion 230 and a flange portion 330 are formed at the rear end side of each of the frame divided body 200 and the frame divided body 300, and the through holes 231 and 331 are formed in the flange portions 230 and 330, respectively. Are formed.

さらに、当該フランジ部230及びフランジ部330の後端側には、半円状の挿入部240及び挿入部340が形成されている。この挿入部240及び挿入部340の内面には、それぞれ挟持面220及び挟持面320が連続して形成されている。また、挿入部240及び挿入部340のそれぞれの外径は、コマフォルダ130のコマフォルダ分割体131及びコマフォルダ分割体132の内径以下となっており、挿入部240及び挿入部340のそれぞれをコマフォルダ分割体131及びコマフォルダ分割体132の内側に差し込むように、取り付けることができる。   Further, a semicircular insertion portion 240 and an insertion portion 340 are formed on the rear ends of the flange portions 230 and 330. A holding surface 220 and a holding surface 320 are formed continuously on the inner surfaces of the insertion portion 240 and the insertion portion 340, respectively. The outer diameter of each of the insertion section 240 and the insertion section 340 is equal to or smaller than the inner diameter of the frame folder divided body 131 and the frame folder divided body 132 of the frame folder 130. It can be attached so as to be inserted into the folder divided body 131 and the frame folder divided body 132.

また、コマ分割体200には、平面視略長方形の被覆剥取刃250が取り付けられており、被覆剥取刃250の先端251は、図3(a)に示すように、挟持面220の内側表面から突出している。そのため、被覆剥ぎコマ400が電線を挟持した状態では、先端251が電線の被覆に臨むように取り付けられることになり、後述するように、被覆剥ぎコマ400が回動すれば、先端251が被覆に切り込み、被覆を剥ぎ取ることができるのである。   Further, a coating stripping blade 250 having a substantially rectangular shape in a plan view is attached to the frame division body 200, and the tip 251 of the coating stripping blade 250 is located inside the holding surface 220 as shown in FIG. It protrudes from the surface. Therefore, in a state where the stripping top 400 holds the electric wire, the tip 251 is attached so as to face the coating of the electric wire, and as described later, when the coating stripping top 400 is rotated, the tip 251 becomes the coating. The cuts and coatings can be stripped off.

また、図3(a)に示すように、コマ分割体300の挟持面320の端部323は、コマ分割体200とコマ分割体300を閉じた状態で、被覆剥取刃250の先端251から離間している。そのため、後述するように、被覆剥取刃250により剥ぎ取られた被覆を、先端251と端部323の間を介して、被覆剥取刃250の後方へ送り出すことができる。さらに、端部323から連続するように傾斜面322が形成されているので、剥ぎ取られた被覆を被覆剥取刃250の後方へ向けて案内しやすくなっている。なお、被覆剥取刃250及びその先端251は、被覆剥ぎコマ400が電線を挟持した状態で、当該電線の軸(図6に示す軸Zを参照)と平行になるように配置されている。   Further, as shown in FIG. 3A, the end 323 of the sandwiching surface 320 of the frame division body 300 is moved from the tip 251 of the coating stripping blade 250 with the frame division body 200 and the frame division body 300 closed. Separated. Therefore, as described later, the coating stripped by the coating stripping blade 250 can be sent to the rear of the coating stripping blade 250 via the space between the tip 251 and the end 323. Furthermore, since the inclined surface 322 is formed so as to be continuous from the end portion 323, it is easy to guide the peeled coating toward the rear of the coating stripping blade 250. Note that the coating stripping blade 250 and the tip 251 thereof are arranged so as to be parallel to the axis of the electric wire (see the axis Z shown in FIG. 6) in a state where the coating stripping piece 400 holds the electric wire.

また、被覆剥取刃250の後方には、被覆脱落防止部260が取り付けられている。この被覆脱落防止部260は、互いに相対するように配置された後端側保持部261及び先端側保持部262から構成されている。そして、この後端側保持部261は、被覆剥取刃250に対して略直角に立設した板部材である。一方、先端側保持部262は、先端側が被覆剥取刃250に対して傾斜した板部材である。   In addition, the coating stripping prevention part 260 is attached to the rear of the coating stripping blade 250. The coating falling-off prevention part 260 includes a rear end side holding part 261 and a front end side holding part 262 arranged to face each other. Further, the rear end side holding portion 261 is a plate member erected substantially perpendicularly to the coating stripping blade 250. On the other hand, the tip side holding portion 262 is a plate member whose tip side is inclined with respect to the coating stripping blade 250.

なお、「後方」とは、被覆剥ぎコマ400が電線を挟持した状態で、被覆剥取刃250を基準として、電線が位置する側を「前方」と定義した場合に、被覆剥取刃250を挟んで、その「前方」の反対側のことを意味する。詳しくは後述するが、被覆剥取刃250の前方側で、被覆剥取刃250により電線の被覆が剥ぎ取られ、その剥ぎ取られて後方に送り出された被覆を、被覆脱落防止部260が保持する。   Note that “rearward” refers to a state in which the stripping piece 400 sandwiches the electric wire and the side where the electric wire is located is defined as “front” with respect to the coating stripping blade 250. It means the opposite side of the "front". As will be described in detail later, at the front side of the coating stripping blade 250, the coating of the electric wire is stripped by the coating stripping blade 250, and the coating stripping prevention unit 260 holds the stripped stripping and sent back. I do.

次に、図4には、コマ分割体200とコマ分割体300を開いた状態での平面図を示す。被覆脱落防止部260の先端側保持部262は、相対する後端側保持部261に向けて傾斜しているので、被覆脱落防止部260の幅L1は、被覆剥取刃250の幅L2よりも狭い。言い換えると、後端側保持部261と先端側保持部262との間隔は、被覆剥取刃250の幅よりも狭くなっている。   Next, FIG. 4 shows a plan view in a state where the frame division body 200 and the frame division body 300 are opened. Since the leading end holding portion 262 of the coating falling prevention portion 260 is inclined toward the opposite rear end holding portion 261, the width L 1 of the coating falling prevention portion 260 is larger than the width L 2 of the coating stripping blade 250. narrow. In other words, the distance between the rear end side holding section 261 and the front end side holding section 262 is smaller than the width of the coating stripping blade 250.

また、コマ分割体200及びコマ分割体300の内面には、先端から後端側まで、それぞれ挟持面220及び挟持面320が連続して形成されている。そして、当該挟持面220と挟持面320には、それぞれ複数の突条(線状に連続した突起部)221及び突条321が、半円周分づつ形成されている。具体的には、複数の突条221は、挟持面220の表面から突出し、互いに所定間隔で平行に形成されている。さらに、突条221は、被覆剥取刃250に直交するように形成されている。   Further, on the inner surfaces of the frame division body 200 and the frame division body 300, a clamping surface 220 and a clamping surface 320 are respectively formed continuously from the front end to the rear end side. A plurality of ridges (protrusions linearly continuous) 221 and ridges 321 are formed on the holding surface 220 and the holding surface 320, each of which is formed by a semicircle. Specifically, the plurality of protrusions 221 protrude from the surface of the holding surface 220 and are formed parallel to each other at a predetermined interval. Further, the protrusion 221 is formed so as to be orthogonal to the coating stripping blade 250.

一方、複数の突条321も同様に、挟持面320の表面から突出し、互いに所定間隔で平行に形成されている。さらに、突条321は、被覆剥取刃250に直交するように形成されている。そのため、コマ分割体200とコマ分割体300を閉じた状態では、突条221と突条321はそれぞれ電線の周方向に連続したリング状となる。   On the other hand, the plurality of protrusions 321 also protrude from the surface of the holding surface 320 and are formed in parallel at a predetermined interval. Further, the protrusion 321 is formed so as to be orthogonal to the coating stripping blade 250. Therefore, when the frame division body 200 and the frame division body 300 are closed, the ridges 221 and 321 each have a ring shape continuous in the circumferential direction of the electric wire.

特に、電線の周囲に雪が着きにくくするためのヒレK(突起)が形成された「ヒレつき電線(難着雪電線)」の被覆を剥ぐ場合、この突条221及び突条321の内径は、当該電線のヒレKが形成された被覆部分の外径よりも僅かに小さくなっているので、被覆剥ぎコマ400により電線を挟持すると、電線の被覆のヒレKに突条221及び突条321が食い込むことになる。   In particular, when stripping the cover of the “finned wire (snow-resistant wire)” on which a fin K (projection) is formed to make it difficult for snow to arrive around the wire, the inner diameters of the ridges 221 and 321 are: Since the electric wire is slightly smaller than the outer diameter of the covering portion where the fin K is formed, when the electric wire is clamped by the covering stripping piece 400, the ridges 221 and 321 bite into the fin K of the electric wire. Will be.

では、次に、本願発明の被覆剥ぎコマ400をコマ駆動工具100に取付け、電線の被覆を剥ぎ取る作業について、図5及び図6を参照して説明する。なお、図6では、説明の都合上、コマフォルダ130を一点鎖線で表し、詳細な構造を省略している。   Next, an operation of attaching the coating stripping piece 400 of the present invention to the frame driving tool 100 and stripping the coating of the electric wire will be described with reference to FIGS. 5 and 6. In FIG. 6, for convenience of explanation, the frame folder 130 is represented by a dashed line, and a detailed structure is omitted.

まず、図5に示すように、被覆剥ぎコマ400をコマ駆動工具100の正面側から取り付ける。具体的には、コマフォルダ130のコマフォルダ分割体132の内面に、コマ分割体200の挿入部240を差し込む様に宛がい、一方、コマフォルダ130のコマフォルダ分割体131の内面に、コマ分割体300の挿入部340を差し込む様に宛がう。その際に、コマ分割体200の貫通孔231を、コマフォルダ分割体132の表面に設けられたフック受けピン133に嵌め込む。同様に、コマ分割体300の貫通孔331を、コマフォルダ分割体131の表面に設けられたフック受けピン133に嵌め込む。これにより、被覆剥ぎコマ400のコマフォルダ130への取付けが完了する。   First, as shown in FIG. 5, the cover peeling piece 400 is attached from the front side of the piece driving tool 100. More specifically, the insertion section 240 of the frame division body 200 is inserted into the inner surface of the frame folder division body 132 of the frame folder 130, while the frame division is divided into the frame folder division body 131 of the frame folder 130. The insertion part 340 of the body 300 is inserted. At this time, the through hole 231 of the frame division body 200 is fitted into the hook receiving pin 133 provided on the surface of the frame folder division body 132. Similarly, the through hole 331 of the frame division body 300 is fitted into the hook receiving pin 133 provided on the surface of the frame folder division body 131. Thus, the attachment of the coating stripping piece 400 to the piece folder 130 is completed.

なお、この嵌め込みが外れないように、フック134をフック受けピン133に掛けておく。一方、被覆剥ぎコマ400をコマフォルダ130から取り外す際は、フック134をフック受けピン133から外し、被覆剥ぎコマ400を正面側に引き抜けばよい。また、以下では、コマフォルダ130と被覆剥ぎコマ400との連結箇所である、貫通孔231とフック受けピン133からなる部分を取付部234と呼び、同様に、貫通孔331とフック受けピン133からなる部分を取付部334と呼ぶ。   Note that the hook 134 is hooked on the hook receiving pin 133 so that the fitting does not come off. On the other hand, when removing the covering strip 400 from the frame folder 130, the hook 134 may be removed from the hook receiving pin 133, and the covering strip 400 may be pulled out to the front side. In the following, a portion consisting of the through hole 231 and the hook receiving pin 133, which is a connecting portion between the top folder 130 and the coating stripping top 400, is referred to as an attachment portion 234, and similarly, from the through hole 331 and the hook receiving pin 133, Is called a mounting portion 334.

次に、図5に示すようにコマフォルダ分割体131とコマフォルダ分割体132が開いた状態で、その開口部Oから電線Wを通す。そして、コマフォルダ分割体131とコマフォルダ分割体132を互いに閉じると、コマ分割体200及びコマ分割体300も閉じ、図6に示すように、電線Wの周囲を挟持面220と挟持面320で挟持することができる。   Next, as shown in FIG. 5, in a state where the frame folder divided body 131 and the frame folder divided body 132 are opened, the electric wire W is passed through the opening O. Then, when the frame folder divided body 131 and the frame folder divided body 132 are closed with each other, the frame divided body 200 and the frame divided body 300 are also closed, and as shown in FIG. Can be pinched.

この状態で、外部動力により、コマ駆動工具100の連結軸114を正転又は逆転させると、その動力がコマフォルダ130に伝わり、コマフォルダ130が電線Wの周方向に正転又は逆転することになる。   In this state, when the connection shaft 114 of the top driving tool 100 is rotated forward or backward by the external power, the power is transmitted to the top folder 130, and the top folder 130 rotates forward or backward in the circumferential direction of the electric wire W. Become.

そして、図6(a)及び(b)に示すように、外部動力により連結軸114を正転させると、コマフォルダ130が時計回りに回転し、コマフォルダ130に取り付けられた被覆剥ぎコマ400も同様に、電線Wの周囲を時計周りに回転していく。そして、被覆剥取刃250の先端251は挟持面220から突出し、電線Wの被覆Gに接触しているので、被覆剥ぎコマ400の回転に伴い、被覆Gを剥離していくことができる。なお、被覆剥ぎコマ400は電線Wの軸Z方向に移動せずに、電線Wを挟持した場所で、そのまま電線Wの周方向に回転するだけであり、これにより、決められた所定の長さ、つまり被覆剥取刃250の長さ分だけ(図4に示す幅L2だけ)、被覆を一括で剥ぎ取るのである。なお、被覆剥取刃250の長さは、一括で剥離したい被覆の軸方向の長さに応じて、適宜変更すればよく、本実施例では、剥ぐ被覆の軸方向の長さは、40mmを想定している。   Then, as shown in FIGS. 6A and 6B, when the connecting shaft 114 is rotated forward by the external power, the top folder 130 rotates clockwise, and the coating strip top 400 attached to the top folder 130 also moves. Similarly, the wire W rotates clockwise around the wire W. Since the tip 251 of the coating stripping blade 250 protrudes from the holding surface 220 and is in contact with the coating G of the electric wire W, the coating G can be peeled off as the coating stripping piece 400 rotates. In addition, the coating stripping piece 400 does not move in the direction of the axis Z of the electric wire W, but simply rotates in the circumferential direction of the electric wire W at the place where the electric wire W is sandwiched. That is, the coating is stripped at once by the length of the coating stripping blade 250 (the width L2 shown in FIG. 4). In addition, the length of the coating stripping blade 250 may be appropriately changed according to the axial length of the coating to be peeled at one time. In the present embodiment, the axial length of the coating to be stripped is 40 mm. I assume.

その際、図6(a)及び(b)に示すように、剥ぎ取られた被覆Gは順次、被覆剥取刃250の後方へ送り出されることになるが、被覆Gの先端H側は、後端側保持部261と先端側保持部262に挟まれて、電線Wの軸Z方向に圧縮されることなる。   At this time, as shown in FIGS. 6A and 6B, the peeled coating G is sequentially sent out to the rear of the coating stripping blade 250, but the leading end H side of the coating G is located at the rear. The electric wire W is compressed in the axis Z direction by being sandwiched between the end-side holding portion 261 and the tip-side holding portion 262.

さらに、そのまま、被覆剥ぎコマ400を時計回りに回転させ、被覆剥ぎコマ400が電線Wの周囲を一周すると、図6(c)に示す状態となる。被覆剥取刃250が電線Wの周囲の被覆Gを全て剥ぎ取ったため電線Wの導線部分Fだけが残り、被覆Gは環状に剥ぎ取られて、被覆脱落防止部260内に保持されている。   Furthermore, when the stripping top 400 is rotated clockwise as it is and the coating stripping top 400 makes a round around the electric wire W, the state shown in FIG. Since the coating stripping blade 250 strips off the entire coating G around the electric wire W, only the conductor portion F of the electric wire W remains, and the coating G is stripped annularly and held in the coating falling-off preventing portion 260.

このように、本願発明の被覆剥ぎコマ400によれば、被覆脱落防止部260の後端側保持部261と先端側保持部262の間隔が、被覆剥取刃250の幅よりも狭くなっているので、被覆剥取刃250の後方へ送り出された被覆Gを圧縮して、脱落しないように保持することができる。具体的には、被覆剥取刃250で剥ぎ取られた被覆Gの幅(電線Wの軸Z方向の長さ)は、被覆剥取刃250の幅(軸Z方向の長さ)と同じになるので、当該幅より狭い間隔の後端側保持部261と先端側保持部262とで挟まれて、圧縮されることになる。したがって、剥ぎ取られた被覆Gは、図6(c)に示すように、被覆脱落防止部260内に確実に保持される。   As described above, according to the coating stripping piece 400 of the present invention, the interval between the rear end side holding part 261 and the front end side holding part 262 of the coating falling prevention part 260 is smaller than the width of the coating stripping blade 250. Therefore, the coating G sent to the rear of the coating stripping blade 250 can be compressed and held so as not to fall off. Specifically, the width (length in the direction of the axis Z of the electric wire W) of the coating G peeled off by the coating stripping blade 250 is the same as the width (the length in the axis Z direction) of the coating stripping blade 250. As a result, it is sandwiched between the rear-end holding portion 261 and the front-end holding portion 262 at an interval smaller than the width, and compressed. Accordingly, the stripped coating G is securely held in the coating falling-off prevention section 260 as shown in FIG.

なお、従来のように被覆Gが螺旋上に剥ぎ取られると、圧縮方向以外に自由に伸縮できてしまい、剥ぎ取られた被覆Gは被覆脱落防止部260外へ飛び出してしまう可能性がある。しかし、本願発明の場合は、環状に剥ぎ取られた被覆Gを対象としており、環状に剥ぎ取られた被覆Gは圧縮方向以外へは伸縮し難いため、圧縮された場所に留まりやすく、被覆脱落防止部260内に保持される。そのため、一括で被覆剥ぎを行い、環状に被覆が剥ぎ取られる場合には、本願の被覆脱落防止部260の構造は簡単かつ最適な構造となる。また、剥ぎ取られた被覆Gが環状に丸まるのは、被覆脱落防止部260の働きによるものではなく、被覆Gの弾性復元力により、元の形状に戻ろうとしたためである。   If the coating G is peeled off on a spiral as in the prior art, the coating G can freely expand and contract in directions other than the compression direction, and the stripped coating G may jump out of the coating falling-off prevention unit 260. However, in the case of the present invention, the coating G that has been stripped annularly is targeted, and the coating G that has been stripped annularly is difficult to expand and contract in directions other than the compression direction. It is held in the prevention unit 260. Therefore, when the coating is peeled off at once and the coating is peeled off in a ring shape, the structure of the coating falling-off prevention unit 260 of the present application is a simple and optimal structure. The reason why the peeled coating G is rounded in an annular shape is not due to the function of the coating falling-off preventing portion 260 but to an attempt to return to the original shape by the elastic restoring force of the coating G.

また、図6(b)に示すように、連結部210及び連結部310は、取付部234及び取付部334とは反対の先端側に位置しているが、当該配置に限定されることはなく、取付部234及び取付部334から先端までの間の任意の場所に配置しても良い。ただ、図6(b)に示しように、連結部210及び連結部310を取付部234及び取付部334とは反対の先端側に位置させることで、コマ分割体200及びコマ分割体300とが閉じて、電線Wを挟持した状態をより強力に維持できる。   In addition, as shown in FIG. 6B, the connecting portion 210 and the connecting portion 310 are located on the distal end side opposite to the mounting portion 234 and the mounting portion 334, but are not limited to this arrangement. , May be arranged at any position between the mounting portion 234 and the mounting portion 334 to the tip. However, as shown in FIG. 6B, by positioning the connecting part 210 and the connecting part 310 on the tip side opposite to the mounting part 234 and the mounting part 334, the frame division body 200 and the frame division body 300 can be connected. When closed, the state in which the electric wire W is sandwiched can be maintained more strongly.

詳しく説明すると、まず、電線Wの被覆Gを被覆剥取刃250で剥離する際は、被覆剥取刃250は被覆Gから大きな抵抗力を受けるため、その抵抗力により、コマ分割体200及びコマ分割体300には、互いに開く方向へ力がかかることになる。そして、取付部234及び取付部334側は、コマフォルダ130と直接固定されているので開きにくいが、コマフォルダ130と直接固定されていない、取付部234及び取付部334の反対側の先端側ほど、コマ分割体200及びコマ分割体300が互いに開きやすくなる。   More specifically, first, when the coating G of the electric wire W is peeled off by the coating stripping blade 250, the coating stripping blade 250 receives a large resistance from the coating G. A force is applied to the divided bodies 300 in a direction to open each other. The mounting portion 234 and the mounting portion 334 are directly fixed to the top folder 130 and thus are difficult to open, but are not directly fixed to the top folder 130 and are closer to the distal end side opposite to the mounting portion 234 and the mounting portion 334. The frame division body 200 and the frame division body 300 are easily opened to each other.

そこで、取付部234及び取付部334とは反対の先端側に、連結部210及び連結部310を配置することで、コマ分割体200及びコマ分割体300とが閉じた状態をより強力に維持できるのである。特に、本願の被覆剥ぎコマ400では、所定の長さだけ被覆を一括で剥離するため、その剥離したい被覆の長さに応じて、被覆剥取刃250の幅が長くなる場合もある。すると、被覆を剥離する際に受ける抵抗力は、その長くなった分大きくなる。よって、このような場合に、取付部234及び取付部334とは反対の先端側に、連結部210及び連結部310を配置することが、特に有効に働くのである。   Therefore, by disposing the connecting portions 210 and 310 on the distal end side opposite to the mounting portions 234 and 334, the closed state of the frame divided bodies 200 and 300 can be more strongly maintained. It is. In particular, in the coating stripping piece 400 of the present application, since the coating is stripped at a time by a predetermined length, the width of the coating stripping blade 250 may be long according to the length of the coating to be stripped. Then, the resistance force received when the coating is peeled increases as the length increases. Therefore, in such a case, arranging the connecting portions 210 and 310 on the tip side opposite to the mounting portions 234 and 334 works particularly effectively.

また、図6(b)に示すように、被覆脱落防止部260の先端側保持部262は、後端側保持部261に向けて傾斜している。そして、被覆剥取刃250の後方へ順次送り出されてくる被覆Gの先端Hは、先端側保持部262の傾斜に沿って後方へ徐々に進んで行く。そのため、被覆Gの先端Hを、その傾斜に沿って、徐々にスムーズに圧縮させることができるのである。   Further, as shown in FIG. 6B, the front-end-side holding portion 262 of the coating falling-off preventing portion 260 is inclined toward the rear-end-side holding portion 261. The distal end H of the coating G sequentially sent to the rear of the coating stripping blade 250 gradually advances rearward along the inclination of the distal end holding portion 262. Therefore, the tip H of the coating G can be gradually and smoothly compressed along the inclination.

なお、本実施例では、後端側保持部261は被覆剥取刃250に対して略直角に立設し、先端側保持部262は被覆剥取刃250に対して傾斜するように立設することで、互いの間隔が、被覆剥取刃250の幅よりも狭くなる構造であるが、これに限定されることはなく、後端側保持部261と先端側保持部262の間隔が被覆剥取刃250の幅より狭くなることで、被覆剥取刃250と同じ幅に剥ぎ取られた被覆を圧縮して、脱落を防止できる構造であればよい。例えば、互いの間隔が被覆剥取刃250の幅より狭ければ、後端側保持部261及び先端側保持部262は互いに平行であってもよい。ただ、図6(b)に示す先端側保持部262のように傾斜していると、徐々に互いの間隔が狭くなるので、剥ぎ取られた被覆をよりスムーズに圧縮することができる。当然ながら、先端側保持部262ではなく、後端側保持部261を傾斜させてもよいし、また、先端側保持部262及び後端側保持部261の両方を互いに傾斜させてもよい。   In this embodiment, the rear end side holding portion 261 stands substantially perpendicular to the coating stripping blade 250, and the front end side holding portion 262 stands upright with respect to the coating stripping blade 250. Accordingly, the interval between the coating stripping blades 250 is narrower than the width of the coating stripping blade 250, but is not limited to this, and the interval between the rear end holding section 261 and the front end holding section 262 is set to be stripped. Any structure may be used as long as it is narrower than the width of the stripping blade 250, thereby compressing the coating stripped to the same width as the coating stripping blade 250 and preventing falling off. For example, if the interval between them is smaller than the width of the coating stripping blade 250, the rear end side holding portion 261 and the front end side holding portion 262 may be parallel to each other. However, if it is inclined like the tip side holding portion 262 shown in FIG. 6 (b), the interval between them gradually narrows, so that the stripped coating can be compressed more smoothly. As a matter of course, the rear end side holding portion 261 may be inclined instead of the front end side holding portion 262, or both the front end side holding portion 262 and the rear end side holding portion 261 may be inclined with respect to each other.

また、図6(b)に示すように、コマ分割体200及びコマ分割体300のそれぞれの挟持面には、複数の突条221及び突条321が、電線Wの軸Z周りの周方向に形成されている。そして、被覆Gを剥ぎ取る際は、この突条221及び突条321が被覆GのヒレKに食い込みながら、被覆剥ぎコマ400が回転するので、電線Wは被覆剥ぎコマ400の中心に強く保持される共に、被覆剥ぎコマ400が電線Wの周方向へ向けて回転する強力な推進力も発生する。   Further, as shown in FIG. 6B, a plurality of ridges 221 and 321 are provided on the holding surfaces of the frame division body 200 and the frame division body 300 in the circumferential direction around the axis Z of the electric wire W. Is formed. When stripping the coating G, the stripping piece 400 rotates while the ridges 221 and 321 bite into the fins K of the coating G, so that the electric wire W is strongly held at the center of the stripping piece 400. At the same time, a strong propulsive force is generated in which the coating stripping piece 400 rotates in the circumferential direction of the electric wire W.

また、剥ぎ取られた被覆Gは、その推進力により、被覆剥取刃250の後方の被覆脱落防止部260へと、強力な力で押し出されていく。さらに、突条221及び突条321は、被覆剥取刃250に直交するように配置されていることから、剥ぎ取られた被覆Gの進む向きは、この突条221及び突条321により、被覆剥取刃250の後方の被覆脱落防止部260に向けて方向付けられる。すると、被覆Gは、相対する先端側保持部262及び後端側保持部261の間に向けて強く押し出されるので、この先端側保持部262及び後端側保持部261によって効果的に圧縮されるのである。   Further, the peeled coating G is pushed out by a strong force toward the coating falling-off preventing portion 260 behind the coating stripping blade 250 by the propulsive force. Further, since the ridges 221 and 321 are arranged so as to be orthogonal to the coating stripping blade 250, the direction in which the stripped coating G advances is determined by the ridges 221 and 321. It is directed toward the coating falling prevention part 260 behind the stripping blade 250. Then, the coating G is strongly pushed out between the opposing front-end holding section 262 and rear-end holding section 261, so that the coating G is effectively compressed by the front-end holding section 262 and the rear-end holding section 261. It is.

なお、当該効果は、被覆GのヒレKに突条221及び突条321が食い込むことで発揮されると説明しているが、被覆GにヒレKがない場合であっても、当該効果と同様の発揮は発揮される。具体的には、図6(a)に示すように、被覆剥取刃250の先端251は、挟持面220の表面から、相対する挟持面320に向けて突出しているので、被覆Gを剥ぎ取る際は、この先端251が、ヒレのない被覆Gを挟持面320に押し当てている。そのため、挟持面320の突条321が、ヒレのない被覆Gに食い込みながら、被覆剥ぎコマ400は電線Wの周方向へ向けて回転することになる。その結果、剥ぎ取られた被覆Gは、被覆脱落防止部260へと、強力な力で押し出されていく。そして、突条321は、被覆剥取刃250に直交するように配置されていることから、剥ぎ取られた被覆Gの進む向きは、被覆脱落防止部260に向けて方向付けられる。すると、被覆Gは、相対する先端側保持部262及び後端側保持部261の間に向けて強く押し出されるので、この先端側保持部262及び後端側保持部261によって効果的に圧縮されるのである。   Although the effect is described as being exerted by the protrusions 221 and 321 biting into the fin K of the coating G, the same effect is obtained even when the coating G does not have the fin K. Is demonstrated. Specifically, as shown in FIG. 6A, since the tip 251 of the coating stripping blade 250 protrudes from the surface of the holding surface 220 toward the opposite holding surface 320, the coating G is stripped. In this case, the tip 251 presses the coating G without fins against the holding surface 320. For this reason, the coating stripping piece 400 rotates in the circumferential direction of the electric wire W while the protrusion 321 of the holding surface 320 bites into the coating G without fins. As a result, the stripped coating G is pushed out to the coating falling prevention unit 260 with a strong force. Since the ridge 321 is arranged so as to be orthogonal to the coating stripping blade 250, the direction in which the stripped coating G advances is directed toward the coating falling prevention unit 260. Then, the coating G is strongly pushed out between the opposing front-end holding section 262 and rear-end holding section 261, so that the coating G is effectively compressed by the front-end holding section 262 and the rear-end holding section 261. It is.

<変形例について>
では、次に、図7及び図8を参照して、本願発明の被覆剥ぎコマ400の変形例である被覆剥ぎコマ400Aについて説明する。なお、図7及び図8に示すように、被覆剥ぎコマ400Aは、電線WA(図8参照)の外径に合わせて、挟持面220A及び挟持面320Aの内径を小さくした点、及び、係止部材350Aを設けた点、並びに、被覆剥取刃250Aに突出部252Aを設けた点が、図3に示す被覆剥ぎコマ400とは異なるが、他の点においては、被覆剥ぎコマ400と同じ構成なので詳細な説明は省略する。なお、図8では、説明の都合上、コマフォルダ130を一点鎖線で表し、詳細な構造を省略している。
<About the modification>
Next, with reference to FIGS. 7 and 8, a description will be given of a coating stripping top 400A which is a modification of the coating stripping top 400 of the present invention. As shown in FIGS. 7 and 8, the coating stripping piece 400A is formed by reducing the inner diameter of the holding surface 220A and the holding surface 320A in accordance with the outer diameter of the electric wire WA (see FIG. 8), and engaging The point that the member 350A is provided and the point that the projecting portion 252A is provided on the coating stripping blade 250A are different from the coating stripping top 400 shown in FIG. Therefore, detailed description is omitted. In FIG. 8, for convenience of explanation, the frame folder 130 is represented by a dashed line, and a detailed structure is omitted.

まず、図7に示すように、被覆剥ぎコマ400Aが対象とする電線WAは、図6に示す電線Wより外径が小さいため、その外径に合わせて、電線WAをしっかりと挟持できるように、挟持面220A及び挟持面320Aの内径を小さくしている。   First, as shown in FIG. 7, since the outer diameter of the electric wire WA targeted by the sheath stripping piece 400A is smaller than the outer diameter of the electric wire W shown in FIG. 6, the electric wire WA should be firmly held in accordance with the outer diameter. The inner diameters of the holding surfaces 220A and 320A are reduced.

また、電線WAの被覆GAを剥ぎ取る際は、図5及び図6を参照して説明したのと同様に、コマ分割体200Aとコマ分割体300Aとが開いた状態で、その開口部Oから電線WAを被覆剥ぎコマ400Aの中心に通す。ただ、電線WAは外径が小さいので、被覆剥ぎコマ400Aの中心に上手く通すことが困難な場合もある。そこで、略U字状の係止部材350Aを、挟持面320Aの両端部に設けた。そして、この係止部材350Aを電線WAに引っ掛けるようにすれば、電線WAは係止部材350Aに案内されて、被覆剥ぎコマ400Aの中心に簡単に誘導されるのである。   When stripping the coating GA of the electric wire WA, as in the case described with reference to FIGS. 5 and 6, in the state where the frame division body 200A and the frame division body 300A are open, The electric wire WA is passed through the center of the stripping top 400A. However, since the electric wire WA has a small outer diameter, it may be difficult to pass the electric wire WA through the center of the covering strip 400A. Therefore, substantially U-shaped locking members 350A are provided at both ends of the holding surface 320A. If the locking member 350A is hooked on the electric wire WA, the electric wire WA is guided by the locking member 350A, and is easily guided to the center of the coating stripping piece 400A.

次に、図8(a)に示すように、被覆剥ぎコマ400Aをコマ駆動工具100のコマフォルダ130に取付け、外部動力により、被覆剥ぎコマ400Aを時計回りに回転させる。すると、被覆剥取刃250Aの先端251Aは、電線WAの被覆GAに接触しているので、被覆剥ぎコマ400Aの回転に伴い、被覆GAを剥離していく。   Next, as shown in FIG. 8A, the coating stripping top 400A is attached to the top folder 130 of the top driving tool 100, and the coating stripping top 400A is rotated clockwise by external power. Then, since the tip 251A of the coating stripping blade 250A is in contact with the coating GA of the electric wire WA, the coating GA is peeled off with the rotation of the coating stripping piece 400A.

ただ、電線WAは外径が小さいので、剥ぎ取られた被覆GAの先端HA側は、被覆剥取刃250Aの先端251Aに近い位置で丸まってしまう可能性がある。すると、先端251A側で被覆GAが丸まってしまい、被覆脱落防止部260A内で、被覆GAを上手く保持できない虞がある。   However, since the outer diameter of the electric wire WA is small, the tip HA side of the stripped coating GA may be rounded at a position close to the tip 251A of the coating stripping blade 250A. Then, the coating GA may be rounded on the tip 251A side, and the coating GA may not be held well in the coating falling-off prevention unit 260A.

そこで、先端251Aの後方に、被覆剥取刃250Aの上面から突出する突出部252Aを設けた。すると、図8(a)に示すように、被覆GAの先端HAが突出部252Aに引っ掛かり、その突出部252Aに引っ掛かった部分を起点に、先端251Aの後方の被覆脱落防止部260A内で、被覆GAは丸まろうとする。そして、そのまま、被覆剥ぎコマ400Aを時計回りに回転させ、被覆剥ぎコマ400Aが電線WAの周囲を一周すると、図8(b)に示す状態となる。被覆剥取刃250Aが電線WAの周囲の被覆GAを全て剥ぎ取ったため、電線WAの導線部分FAだけが残り、被覆GAは環状に剥ぎ取られて、被覆脱落防止部260A内で圧縮されて保持されている。   Therefore, a protruding portion 252A protruding from the upper surface of the coating stripping blade 250A is provided behind the tip 251A. Then, as shown in FIG. 8 (a), the tip HA of the coating GA is hooked on the protrusion 252A, and the portion hooked on the protrusion 252A is used as a starting point in the coating falling prevention portion 260A behind the tip 251A. GA tries to curl. Then, the cover peeling top 400A is rotated clockwise as it is, and when the cover peeling top 400A makes a round around the electric wire WA, a state shown in FIG. 8B is obtained. Since the coating stripping blade 250A strips off the entire coating GA around the electric wire WA, only the conductive wire portion FA of the electric wire WA remains, and the coating GA is stripped in an annular shape and is compressed and held in the coating falling-off preventing portion 260A. Have been.

なお、図7(c)に示すように、被覆剥取刃250Aの突出部252Aは、被覆剥取刃250Aの全長にわたり直線状に、かつ断面略三角形状に形成されているが、これに限定されない。突出部252Aは、先端251Aの後方に設けられると共に、剥離された電線WAの先端HAが引っ掛かるように被覆剥取刃250Aの表面から突出していれば、どのような形状であってもよい。   As shown in FIG. 7C, the protruding portion 252A of the coating stripping blade 250A is formed linearly over the entire length of the coating stripping blade 250A and in a substantially triangular cross section, but is not limited thereto. Not done. The protruding portion 252A may have any shape as long as it is provided behind the tip 251A and protrudes from the surface of the coating stripping blade 250A so that the tip HA of the peeled wire WA is caught.

なお、本願発明の被覆剥ぎコマは、上記の実施例に限定されず、特許請求の範囲に記載された範囲、実施形態の範囲で、種々の変形例、組み合わせが可能であり、これらの変形例、組み合わせもその権利範囲に含むものである。

In addition, the coating stripping piece of the present invention is not limited to the above-described examples, and various modifications and combinations are possible within the scope described in the claims and the scope of the embodiments. , And combinations are also included in the scope of rights.
