Description

本発明は、電線の中間部における一定長の絶縁被覆を剥離除去するために用いられる電線皮剥工具に関する。 TECHNICAL FIELD The present invention relates to an electric wire stripping tool used for stripping and removing a certain length of insulating coating in the intermediate portion of an electric wire.

配電設備の工事を行うにあたり、部分的な停電を行うためにバイパス工事や接地工事が行われることがある。その際、バイパスや接地の経路を形成するために電線の中間部における絶縁被覆を剥ぎ取り、導体である芯線を露出させて、そこにバイパス器具や接地器具を接続する作業を活線状態のままで実施することが求められる。 When constructing power distribution facilities, bypass construction and grounding construction may be carried out in order to carry out partial power outages. At that time, in order to form a path for bypass or grounding, the insulation coating is stripped from the middle part of the wire, the conductor core is exposed, and the work of connecting the bypass device or grounding device to it is performed while the wire is still live. It is required to be implemented in

このような求めに応じるため、作業者が電線等に直接触れることなく、電線の中間部で絶縁被覆を螺旋状に切削して剥ぎ取ることのできる電線皮剥工具が開発されている（例えば、特許文献１から３）。そして、所定の工事が終了した後は、芯線が露出した箇所にプラスチック製の絶縁カバーを装着することで復旧が図られる。 In order to meet such demands, a wire stripping tool has been developed that can spirally cut and strip the insulation coating at the middle of the wire without the operator having to directly touch the wire (for example, patented References 1 to 3). After the predetermined construction work is completed, restoration is achieved by attaching a plastic insulating cover to the portion where the core wire is exposed.

特許文献１から３に開示された電線皮剥工具は、ともに電線の中間部の絶縁被覆を螺旋状に剥ぐための切削刃を電線の長手方向に対して回転移動させることで絶縁被覆を剥ぎ取るようになっている。 The electric wire stripping tools disclosed in Patent Literatures 1 to 3 are designed to peel off the insulating coating by rotating a cutting blade for spirally stripping the insulating coating in the middle portion of the electric wire in the longitudinal direction of the electric wire. It has become.

また、これら電線皮剥工具を工事の対象となる電線に着脱する際には、開口させた電線皮剥工具で電線を挟み込むようになっている。 Moreover, when these wire stripping tools are attached to and detached from the wire to be constructed, the wire is sandwiched between the opened wire stripping tools.

しかしながら、従来の電線皮剥工具では、当該電線皮剥工具で電線を挟み込んだとき、電線皮剥工具を完全に閉じきることができず、不完全に閉じた状態で絶縁被覆を剥ぎ取っていくことから、絶縁被覆の剥ぎ取り残しが生じる等の問題が発生するおそれがあった。 However, with conventional wire stripping tools, when a wire is pinched by the wire stripping tool, the wire stripping tool cannot be completely closed, and the insulation coating is stripped off in an incompletely closed state. There is a possibility that problems such as the insulation coating being left unstripped may occur.

この理由としては、電線皮剥工具を構成する各部材に設計上の公差があることから、電線皮剥工具自体にいわゆる「遊び」があり、電線皮剥工具の回転機構を完全に閉じきることができない点が考えられる。 The reason for this is that each component of the wire stripping tool has a design tolerance, so the wire stripping tool itself has a so-called "play", and the rotating mechanism of the wire stripping tool cannot be completely closed. can be considered.

また、電線皮剥工具は、高所に配設された電線に対して作業者が手動操作して使用されるものであることから、切削刃を電線に対して回転させる回転力しかこの電線皮剥工具に加えることができず、回転機構を完全に閉じる力を直接的に当該回転機構に作用させることができていない点が考えられる。 In addition, since the wire stripping tool is manually operated by an operator to work on the wire placed at a high place, only the rotational force for rotating the cutting blade with respect to the wire can be applied to the wire stripping tool. It is conceivable that the force for completely closing the rotating mechanism cannot be applied directly to the rotating mechanism.

本発明は、このような課題に鑑みてなされたものであり、その目的は、従来の電線皮剥工具と同じく切削刃を電線に対して回転させる回転力を加えることにより、回転機構を完全に閉じることのできる電線皮剥工具を提供することにある。 The present invention has been made in view of such problems, and its object is to completely close the rotating mechanism by applying a rotational force to rotate the cutting blade with respect to the wire as in the conventional wire stripping tool. To provide an electric wire stripping tool capable of

（電線皮剥工具１００の構成）
図１は、本発明が適用された実施形態に係る電線皮剥工具１００を示す。本実施形態に係る電線皮剥工具１００は、大略、開閉機構１１０と、回転機構２００と、皮剥機構３００とで構成されている。なお、図１は、電線皮剥工具１００から皮剥機構３００が取り外された状態を示す斜視図であり、図２は、皮剥機構３００を示す斜視図である。 (Structure of wire stripping tool 100)
FIG. 1 shows an electric wire stripping tool 100 according to an embodiment to which the present invention is applied. The wire stripping tool 100 according to the present embodiment is roughly composed of an opening/closing mechanism 110 , a rotating mechanism 200 and a stripping mechanism 300 . 1 is a perspective view showing a state in which the stripping mechanism 300 is removed from the wire stripping tool 100, and FIG. 2 is a perspective view showing the stripping mechanism 300. FIG.

なお、本明細書全体を通して、電線の内部にある通電部材を芯線Ｓといい、当該芯線Ｓの外側を覆う絶縁部材を絶縁被覆Ｈという。さらに、絶縁被覆Ｈによって覆われた芯線Ｓの全体を被覆電線Ｌあるいは単に電線Ｌという。 Throughout the present specification, the current-carrying member inside the electric wire is referred to as the core wire S, and the insulating member covering the outer side of the core wire S is referred to as the insulating coating H. Further, the entire core wire S covered with the insulating coating H is called the covered wire L or simply the wire L. As shown in FIG.

開閉機構１１０は、作業者が操作棒を用いて操作することにより、電線Ｌを挟んで回転機構２００および皮剥機構３００を開閉するとともに、当該回転機構２００および皮剥機構３００を回転させて電線Ｌから絶縁被覆Ｈを剥離除去するための機構である。 The opening/closing mechanism 110 opens and closes the rotating mechanism 200 and the peeling mechanism 300 with the electric wire L interposed therebetween by being operated by an operator using an operation rod, and rotates the rotating mechanism 200 and the peeling mechanism 300 to rotate the electric wire L. It is a mechanism for peeling and removing the insulating coating H.

図３を用いてこの開閉機構１１０について説明する。本実施形態に係る開閉機構１１０は、大略、回転ベース部材１１２と、保持部材１１８と、開閉部材１２２とを備えている。 The opening/closing mechanism 110 will be described with reference to FIG. The opening/closing mechanism 110 according to this embodiment generally includes a rotating base member 112 , a holding member 118 , and an opening/closing member 122 .

回転ベース部材１１２は、ベース本体１２３と、傘歯車１２４と、操作棒接続部材１２５とを有している。作業者が操作棒を操作棒接続部材１２５に取り付けた後、当該操作棒を回して操作棒接続部材１２５に回転力を付与することにより、傘歯車１２４が回転するようになっている。 The rotating base member 112 has a base body 123 , a bevel gear 124 and an operating rod connecting member 125 . After the operator attaches the operation rod to the operation rod connection member 125, the bevel gear 124 is rotated by rotating the operation rod to apply a rotational force to the operation rod connection member 125. As shown in FIG.

保持部材１１８は、回転機構２００を所定の位置で保持するための略「Ｃ」字状の部材であり、下端部が回転ベース部材１１２の側面に４つの保持部材固定ネジ１３３で固定されている（図１２等を参照）。また、保持部材１１８における略「Ｃ」字状の内縁から少し離れた位置には、同じく略「Ｃ」字状の段部１２６が形成されており、この段部１２６は回転機構２００が回転する際のガイドとなっている。つまり、図３において、段部１２６よりも外側は、段部１２６よりも内側の部分よりも厚く形成されている。さらに、段部１２６は、図中における略１時付近から１２時付近にかけて「Ｃ」字の中心から急激に遠ざかっていくように形成されている。 The holding member 118 is a substantially "C"-shaped member for holding the rotation mechanism 200 at a predetermined position, and the lower end is fixed to the side surface of the rotation base member 112 with four holding member fixing screws 133. (See FIG. 12, etc.). Also, at a position a little away from the inner edge of the substantially "C" shape in the holding member 118, a similarly substantially "C" shaped stepped portion 126 is formed. It is a true guide. That is, in FIG. 3 , the outer side of the stepped portion 126 is formed thicker than the inner side of the stepped portion 126 . Further, the stepped portion 126 is formed so as to rapidly move away from the center of the "C" from approximately 1 o'clock to 12 o'clock in the figure.

また、段部１２６よりも外側の表面における図中３時付近からは、ロック本体押圧部材１２８が突設されている。本実施形態ではロック本体押圧部材１２８としてピン状のものが使用されているが、ロック本体押圧部材１２８の形状はこれに限定されるものではなく、ブロック状のものやその他の形状のものを使用してもよい。 A lock body pressing member 128 projects from the surface outside the stepped portion 126 from around 3 o'clock in the drawing. In this embodiment, a pin-shaped lock body pressing member 128 is used, but the shape of the lock body pressing member 128 is not limited to this, and a block-shaped or other shape may be used. You may

また、保持部材１１８の図中１１時付近（この部分は段部１２６よりも内側の厚さと同じ厚さに形成されている）には、開閉部材１２２が回動自在に取り付けられている。 An open/close member 122 is rotatably attached to the holding member 118 in the vicinity of 11 o'clock in the drawing (this portion is formed to have the same thickness as the inner thickness of the stepped portion 126).

開閉部材１２２は、湾曲したレバー状に形成されており、その一端部が軸支部材１３０によって保持部材１１８に対して回動自在に取り付けられている。また、開閉部材１２２の他端部にはフック部１３２が形成されている。 The opening/closing member 122 is formed in a curved lever shape, and one end thereof is rotatably attached to the holding member 118 by a pivot member 130 . A hook portion 132 is formed at the other end portion of the opening/closing member 122 .

さらに、開閉部材１２２の一端からは、軸支部材１３０と平行に回動規制ピン１３４が保持部材１１８に向けて突設されている。保持部材１１８における、回動規制ピン１３４の先端に対応する位置には、回動規制ピン嵌挿孔１３６が形成されており、回動規制ピン１３４の先端部がこの回動規制ピン嵌挿孔１３６に挿設されている。回動規制ピン嵌挿孔１３６は、回動規制ピン１３４の先端部の断面よりも大きく形成されており、この回動規制ピン嵌挿孔１３６の内側で回動規制ピン１３４が動くことができる範囲において、開閉部材１２２の他端部（つまり、フック部１３２）が回動できるようになっている。 Further, a rotation restricting pin 134 projects from one end of the opening/closing member 122 toward the holding member 118 in parallel with the pivot member 130 . A rotation restricting pin insertion hole 136 is formed at a position corresponding to the tip of the rotation restricting pin 134 in the holding member 118, and the tip of the rotation restricting pin 134 fits into this rotation restricting pin fitting insertion hole. 136 is inserted. The rotation restricting pin insertion hole 136 is formed to be larger in cross section than the tip of the rotation restricting pin 134 , and the rotation restricting pin 134 can move inside the rotation restricting pin insertion hole 136 . Within this range, the other end of the opening/closing member 122 (that is, the hook portion 132) can rotate.

なお、軸支部材１３０には開閉部材付勢部材１３８が被せられており、この開閉部材付勢部材１３８の一端は保持部材１１８に取り付けられており、他端は開閉部材１２２に取り付けられている。この開閉部材付勢部材１３８の弾性により、開閉部材１２２は、当該開閉部材１２２の他端部（フック部１３２）が開閉部材１２２の「Ｃ」字状部分の中心に向けて付勢されている。なお、本実施形態では、開閉部材付勢部材１３８としてねじりバネが使用されているが、開閉部材１２２を上述した方向に付勢できるものであれば、他の形態であってもよい。 The pivot member 130 is covered with an opening/closing member biasing member 138 , one end of which is attached to the holding member 118 , and the other end is attached to the opening/closing member 122 . . Due to the elasticity of the opening/closing member biasing member 138, the other end (hook portion 132) of the opening/closing member 122 is biased toward the center of the "C"-shaped portion of the opening/closing member 122. . In this embodiment, a torsion spring is used as the opening/closing member urging member 138, but other forms may be used as long as they can urge the opening/closing member 122 in the above-described directions.

次に、図４および図５を用いて回転機構２００について説明する。本実施形態に係る回転機構２００は、大略、回転力受け部材２０２と、ガイド部材２０４と、皮剥機構取付部材２０６と、開閉ロック機構２０８とを備えている。 Next, the rotating mechanism 200 will be described with reference to FIGS. 4 and 5. FIG.

A circular rotational force receiving member 202 is formed by combining the first receiving member 210 and the second receiving member 212 .

第１受け部材２１０および第２受け部材２１２の外周縁部には、回転ベース部材１１２に設けられた傘歯車１２４に噛み合う歯車２１４が形成されており、操作棒を回転させることによって傘歯車１２４が回転することにより、回転力受け部材２０２も回転するようになっている。 A gear 214 meshing with a bevel gear 124 provided on the rotating base member 112 is formed on the outer peripheral edge of the first receiving member 210 and the second receiving member 212, and the bevel gear 124 is engaged by rotating the operating rod. By rotating, the rotational force receiving member 202 also rotates.

また、第１受け部材２１０および第２受け部材２１２の表面には複数の第１貫通孔２１６が形成されている。 A plurality of first through holes 216 are formed in the surfaces of the first receiving member 210 and the second receiving member 212 .

ガイド部材２０４は、回転力受け部材２０２の背面側に取り付けられる、回転力受け部材２０２よりも小径の円形ドーナツ状の部材であり、一対の半円弧状部材である第１ガイド部材２１８と第２ガイド部材２２０とで構成されている。これら第１ガイド部材２１８および第２ガイド部材２２０を組み合わせることによって円形のガイド部材２０４が形成される。 The guide member 204 is a circular donut-shaped member with a diameter smaller than that of the rotational force receiving member 202 and attached to the back side of the rotational force receiving member 202. and a guide member 220 .

The cutting tool post member 332 according to the present embodiment includes a cutting tool post member main body portion 348 formed in a substantially rectangular shape, and a base portion 350 protruding from the cutting blade post member main body portion 348 in a direction perpendicular thereto. have. The cutting blade 330 has a side surface in contact with the cutting blade base member body portion 348 and a bottom surface in contact with the base portion 350 . A second bolt insertion hole 352 through which the cutting blade rotation center bolt 338 is inserted is also formed at a position corresponding to the bolt insertion hole 346 of the cutting blade 330 in the cutting blade post member body portion 348 .

被覆屑誘導プレート３３４は、台部３５０に対向する切削刃３３０の天面に取り付けられた板材である。また、この被覆屑誘導プレート３３４は、切削刃３３０によって剥ぎ取られてきた電線Ｌの被覆屑が作業の進捗とともに伸びてきたときに、当該被覆屑の先端部が被覆屑落下防止部材３３６に向けて進んでいくようにガイドする役割を有している。 The coating dust guide plate 334 is a plate material attached to the top surface of the cutting blade 330 facing the base portion 350 . In addition, when the covering scraps of the wire L stripped off by the cutting blade 330 extend as the work progresses, the covering scraps guide plate 334 directs the tip of the covering scraps toward the covering scraps fall prevention member 336. It has the role of guiding you to move forward.

被覆屑落下防止部材３３６は、電線皮剥工具１００による作業が進んで行くにつれて伸びてくる電線Ｌの被覆屑が不所望に飛び散ってしまったり落下したりするのを防止する役割を有する部材である。本実施形態に係る被覆屑落下防止部材３３６は、ベース部３５４と、被覆屑保持部３５６とを有している。 The covering dust fall prevention member 336 is a member that has a role of preventing the covering dust of the electric wire L, which extends as the work by the electric wire stripping tool 100 progresses, from undesirably scattering or falling. The covering dust fall prevention member 336 according to this embodiment has a base portion 354 and a covering dust holding portion 356 .

ベース部３５４は、切削刃３３０を外側から覆う、断面がＬ字状に形成された略板状材であり、その略中央部には、切削刃回動中心ボルト３３８が挿通される第３ボルト挿通孔３５８が形成されている。 The base portion 354 is a substantially plate-shaped member having an L-shaped cross section that covers the cutting blade 330 from the outside. An insertion hole 358 is formed.

また、ベース部３５４は、留めボルト３４４によって皮剥機構本体３０２の第２本体部材３１２に直接固定されている。 Also, the base portion 354 is directly fixed to the second body member 312 of the skin peeling mechanism body 302 by fastening bolts 344 .

被覆屑保持部３５６は、切削刃３３０によって剥ぎ取られた絶縁被覆Ｈを引っかけて保持するようにして、この絶縁被覆Ｈが電線皮剥工具１００から不所望に落下しないようにする役割を有している。本実施形態に係る被覆屑保持部３５６は、切削刃３３０から離間する方向に伸びるほぼ一定幅短冊状の板状部３６０と、この板状部３６０における切削刃３３０から見て遠い側の端から略直交する方向に伸びるほぼ一定幅短冊状の被覆屑係止部３６２とを有している。また、板状部３６０の幅と、被覆屑係止部３６２の幅とは、ほぼ同じ寸法になっている。 The coating dust holding part 356 hooks and holds the insulating coating H stripped off by the cutting blade 330, and has a role of preventing the insulating coating H from undesirably falling from the wire stripping tool 100. there is The coated dust holding portion 356 according to the present embodiment includes a strip-shaped plate-like portion 360 extending in a direction away from the cutting blade 330, and an end of the plate-like portion 360 farther from the cutting blade 330. It has a substantially constant-width strip-shaped covering scrap locking portion 362 extending in a substantially orthogonal direction. Further, the width of the plate-like portion 360 and the width of the coating scrap locking portion 362 are approximately the same size.

切削刃回動中心ボルト３３８は、切削機構３０４を皮剥機構本体３０２に取り付けるための部材である。切削刃回動中心ボルト３３８の先端部を被覆屑落下防止部材３３６における第３ボルト挿通孔３５８、カラー３４０、付勢部材３４２、切削刃３３０におけるボルト挿通孔３４６、および、切削刃台部材３３２における第２ボルト挿通孔３５２の順に挿通していき、最後に、皮剥機構本体３０２における第２本体部材３１２に形成された切削刃回動中心ボルト受け穴３６４に挿設・螺合することにより、切削機構３０４を皮剥機構本体３０２に取り付けられるようになっている。 The cutting blade rotation center bolt 338 is a member for attaching the cutting mechanism 304 to the peeling mechanism main body 302 . The tip portion of the cutting blade rotation center bolt 338 is inserted through the third bolt insertion hole 358 in the coating chip drop prevention member 336, the collar 340, the biasing member 342, the bolt insertion hole 346 in the cutting blade 330, and the cutting blade post member 332. The second bolt insertion hole 352 is inserted in order, and finally the cutting blade rotation center bolt receiving hole 364 formed in the second main body member 312 of the skin peeling mechanism main body 302 is inserted and screwed, thereby cutting. A mechanism 304 is adapted to be attached to the skinning mechanism body 302 .

上述のように、被覆屑落下防止部材３３６は、そのベース部３５４が留めボルト３４４によって皮剥機構本体３０２に固定されている。このため、被覆屑落下防止部材３３６と皮剥機構本体３０２との間で、切削刃回動中心ボルト３３８を中心として、切削刃３３０が回動自在に保持されている。 As described above, the covering dust fall prevention member 336 is fixed to the peeling mechanism main body 302 by the fastening bolt 344 at its base portion 354 . For this reason, the cutting blade 330 is rotatably held around the cutting blade rotation center bolt 338 between the coating dust fall prevention member 336 and the peeling mechanism main body 302 .

カラー３４０は、切削刃３３０と被覆屑落下防止部材３３６との間にクリアランスを設けて、当該間に配設される付勢部材３４２の配置スペースを確保するための円筒状部材である。 The collar 340 is a cylindrical member that provides a clearance between the cutting blade 330 and the coating dust drop prevention member 336 to secure an arrangement space for the urging member 342 that is arranged therebetween.

付勢部材３４２は、被覆屑落下防止部材３３６と皮剥機構本体３０２との間において回動自在に保持されている切削刃３３０が所定の方向に回動するように付勢するための部材であり、本実施形態では巻きバネが使用されている。もちろん、切削刃３３０を所定の方向に付勢できれば、巻きバネに限定されることはない。 The biasing member 342 is a member for biasing the cutting blade 330, which is rotatably held between the coating dust drop prevention member 336 and the peeling mechanism main body 302, to rotate in a predetermined direction. , in this embodiment a coil spring is used. Of course, as long as the cutting blade 330 can be biased in a predetermined direction, it is not limited to a spiral spring.

付勢部材３４２が切削刃３３０を回動付勢する方向は、切削刃３３０における電線Ｌを切削する端が電線Ｌの中心に向かう方向である。このように付勢することで、切削刃３３０における電線Ｌを切削する端が切削を進めていくにつれて当該電線Ｌの中心に進んでいき、絶縁被覆Ｈを剥ぎ取っていけるようになっている。なお、切削刃３３０における電線Ｌを切削する端が芯線Ｓに到達するところまで進むと、切削刃台部材３３２における切削刃台部材本体部３４８の先端が芯線Ｓあるいは絶縁被覆Ｈに接触することにより、切削刃３３０がそれ以上進んで芯線Ｓに触れてしまうのを規制するようになっている。 The direction in which the biasing member 342 rotationally biases the cutting blade 330 is the direction in which the end of the cutting blade 330 that cuts the electric wire L faces the center of the electric wire L. As shown in FIG. By biasing in this way, the end of the wire L cut by the cutting blade 330 advances toward the center of the wire L as the cutting progresses, and the insulation coating H can be stripped off. When the end of the cutting blade 330 that cuts the electric wire L reaches the core wire S, the tip of the cutting blade base member main body 348 of the cutting blade base member 332 comes into contact with the core wire S or the insulation coating H. , the cutting edge 330 is prevented from advancing further and touching the core wire S.

本実施形態に係る切削機構３０４によれば、電線Ｌの絶縁被覆Ｈを切削刃３３０で切削していくことによって螺旋状に伸びて発生していく被覆屑が、被覆屑誘導プレート３３４にガイドされて被覆屑保持部３５６に進み、被覆屑保持部３５６の板状部３６０に巻き付いていく。さらに絶縁被覆Ｈの切削を進めていくと、被覆屑は被覆屑保持部３５６の被覆屑係止部３６２に達し、さらに被覆屑保持部３５６を越えて伸びていく。 According to the cutting mechanism 304 according to the present embodiment, the coating waste generated spirally by cutting the insulation coating H of the electric wire L with the cutting blade 330 is guided by the coating waste guiding plate 334. It advances to the coating waste holding portion 356 and winds around the plate-like portion 360 of the coating waste holding portion 356 . As the insulation coating H is further cut, the coating waste reaches the coating waste retaining portion 362 of the coating waste holding portion 356 and extends beyond the coating waste holding portion 356 .

このように被覆屑が被覆屑係止部３６２を越えて伸びていくと、当該被覆屑はその一部分で必ず被覆屑係止部３６２に係合している状態を保つことになる。このため、絶縁被覆Ｈの剥ぎ取り作業中や、作業終了時に被覆屑が電線Ｌから離れたとき、被覆屑が不所望に電線皮剥工具１００から離れていくことがなくなる。 When the covering chips extend beyond the covering chips locking portion 362 in this way, the covering chips are always engaged with the coating chips locking portion 362 at a part thereof. Therefore, when the coating scraps are separated from the wire L during the work of stripping the insulation coating H or at the end of the work, the coating scraps do not undesirably leave the wire stripping tool 100 .

ところで、被覆屑保持部３５６に似た役割を有する「被覆屑巻付棒」に関する技術が特許文献３に開示されているが、この「被覆屑巻付棒」は、その基端部の外径が剥離された被覆屑が螺旋状にカールして形成される円筒状の内径よりも小さく形成され、中間部が基端部の外径のまま一定の長さで延び、終端部の外径が基端部の外径よりも大きなテーパー状に形成されている。 By the way, Patent Document 3 discloses a technique related to a "coating dust winding rod" having a role similar to the coating dust holding portion 356, but this "coating dust winding rod" has an outer diameter is formed to be smaller than the inner diameter of the cylinder formed by spirally curling the peeled coating debris, the intermediate portion extends for a certain length with the outer diameter of the base end portion, and the outer diameter of the terminal end portion is It is formed in a tapered shape larger than the outer diameter of the base end.

一般に、切削刃３３０で切削し剥ぎ取った被覆屑は、外気温が低い冬場では、被覆屑自体が硬くなりやすく、螺旋状になったときにおける当該螺旋の径が大きくなりやすい。つまり、外気温が低い場合、被覆屑は比較的大きな螺旋状になっていく。 In general, the covering scraps cut and stripped off by the cutting blade 330 tend to harden in winter when the outside air temperature is low, and the diameter of the spiral tends to increase when formed into a spiral. In other words, when the outside air temperature is low, the coating waste becomes a relatively large spiral.

これに対し、外気温が高い夏場では、被覆屑自体が硬くなりにくいことから、螺旋状になったときにおける当該螺旋の径が小さくなりやすい。このとき、特許文献３における「被覆屑巻付棒」のように終端部をその外径が基端部の外径よりも大きなテーパー状に形成すると、螺旋状の被覆屑が当該終端部でつかえてしまい、被覆屑がダマになってしまうおそれがあった。 On the other hand, in the summer when the outside air temperature is high, the coating waste itself is hard to harden, so the diameter of the spiral tends to be small when formed into a spiral. At this time, if the terminal end portion is formed in a tapered shape with an outer diameter larger than the outer diameter of the base end portion as in the "coated dust wrapped bar" in Patent Document 3, the spiral coated debris will be stuck at the terminal end portion. There was a risk that the coating waste would clump together.

この点、本実施形態に係る被覆屑落下防止部材３３６における被覆屑保持部３５６のように、切削刃３３０から離間する方向に伸びるほぼ一定幅短冊状の板状部３６０と、この板状部３６０における切削刃３３０から見て遠い側の端から略直交する方向に伸びるほぼ一定幅短冊状の被覆屑係止部３６２とで構成することにより、螺旋の径が小さい場合であっても被覆屑が被覆屑係止部３６２につかえてしまう可能性を低くして、被覆屑がダマになってしまうのを回避することができる。 In this regard, like the coating dust holding portion 356 of the coating dust fall prevention member 336 according to the present embodiment, a plate-like portion 360 having a substantially constant width strip extending in a direction away from the cutting blade 330 and the plate-like portion 360 By constructing a substantially constant-width strip-shaped coated chip locking portion 362 extending in a substantially orthogonal direction from the end on the far side when viewed from the cutting edge 330, even if the diameter of the spiral is small, coated chips can be It is possible to reduce the possibility that the coating waste will be caught in the coating waste locking portion 362, thereby avoiding clumping of the coating waste.

なお、本実施形態に係る被覆屑保持部３５６は、板状部３６０と被覆屑係止部３６２とで略「Ｌ」字状に形成されているが、板状部３６０を中心にして対称方向に別の（第２の）被覆屑係止部３６２を加えることによって略「Ｔ」字状に形成してもよい（図１８参照）。 In addition, although the coating dust holding portion 356 according to the present embodiment is formed in a substantially “L” shape by the plate-like portion 360 and the coating dust locking portion 362, it is formed in a symmetrical direction with respect to the plate-like portion 360. It may also be formed into a substantially "T" shape by adding another (second) coating scrap locking portion 362 (see FIG. 18).

（実施形態に係る電線皮剥工具１００の動作）
次に上述した電線皮剥工具１００の動作について説明する。図１２は、基準状態にある当該電線皮剥工具１００を示している。この状態から、操作棒を用いて開閉機構１１０の操作棒接続部材１２５を順方向に回すと回転機構２００が反時計回りに回転する。開閉機構１１０の操作棒接続部材１２５を逆方向に回すと回転機構２００が時計回りに回転する。 (Operation of the wire stripping tool 100 according to the embodiment)
Next, the operation of the wire stripping tool 100 described above will be described. FIG. 12 shows the wire stripping tool 100 in its nominal state. From this state, when the operating rod is used to rotate the operating rod connection member 125 of the opening/closing mechanism 110 in the forward direction, the rotation mechanism 200 rotates counterclockwise. When the operating rod connection member 125 of the opening/closing mechanism 110 is turned in the opposite direction, the rotating mechanism 200 rotates clockwise.

最初に、操作棒接続部材１２５を逆方向に回していき、回転機構２００を開いた状態にするまでの動作について説明する。図１２に示す状態から操作棒接続部材１２５を逆方向に回していくと、ロック本体２７６における外向突設部２８６が開閉部材１２２のフック部１３２に係合する。引き続き操作棒接続部材１２５を逆方向に回していくと、回転機構２００が時計回りに回転し、図１３に示すように、このロック本体２７６が取り付けられたガイド部材２０４の第１ガイド部材２１８、およびこれに固定された回転力受け部材２０２の第１受け部材２１０、皮剥機構取付部材２０６の第１背面側部材２３４および第１正面側部材２３８、さらに、皮剥機構３００における第１本体部材３１０における各一方端が、組み合わされる第２ガイド部材２２０、第２受け部材２１２、第２背面側部材２３６および第２正面側部材２４０、さらに、皮剥機構３００における第２本体部材３１２から離間していき、回転機構２００および皮剥機構３００が開いた状態となる。さらに操作棒接続部材１２５を逆方向に回していくと、図１４に示すように、さらに離間の度合いが増して、回転機構２００および皮剥機構３００が完全に開いた状態となる。この状態で、電線Ｌを電線皮剥工具１００の内側から出し入れすることができる。 First, the operation of rotating the operating rod connection member 125 in the opposite direction until the rotation mechanism 200 is opened will be described. When the operating rod connecting member 125 is rotated in the opposite direction from the state shown in FIG. When the operating rod connecting member 125 is continued to be rotated in the opposite direction, the rotation mechanism 200 rotates clockwise, and as shown in FIG. And the first receiving member 210 of the rotational force receiving member 202 fixed thereto, the first rear side member 234 and the first front side member 238 of the peeling mechanism mounting member 206, and the first body member 310 in the peeling mechanism 300 Each one end is separated from the second guide member 220, the second receiving member 212, the second back side member 236 and the second front side member 240 that are combined, and the second main body member 312 in the peeling mechanism 300, The rotating mechanism 200 and the peeling mechanism 300 are opened. As the operating rod connecting member 125 is further rotated in the opposite direction, as shown in FIG. 14, the degree of separation increases and the rotating mechanism 200 and the peeling mechanism 300 are completely opened. In this state, the wire L can be taken in and out from the inside of the wire stripping tool 100 .

次に、操作棒接続部材１２５を順方向に回していき、回転機構２００を閉じて電線Ｌから絶縁被覆Ｈを剥ぎ取る動作について説明する。図１２に示す基準状態から操作棒接続部材１２５を順方向に回していくと、ガイド部材２０４が図中反時計回りに回転していき、図１５に示すように、開閉ロック機構２０８を構成するロック本体２７６の外向突設部２８６の外面が開閉機構１１０の保持部材１１８に突設されたロック本体押圧部材１２８に当接する。操作棒接続部材１２５を順方向にさらに回していくと、ロック本体押圧部材１２８に押されたロック本体２７６のフック部２８４がさらに内側（中心側）に向けて回動することとなり、当該フック部２８４が確実にロック本体係合部材２８０と係合するようになる。 Next, the operation of rotating the operating rod connecting member 125 in the forward direction, closing the rotating mechanism 200, and stripping the insulating coating H from the electric wire L will be described. As the operating rod connecting member 125 is rotated forward from the reference state shown in FIG. 12, the guide member 204 rotates counterclockwise in the drawing, forming an open/close lock mechanism 208 as shown in FIG. The outer surface of the outward projecting portion 286 of the lock body 276 contacts the lock body pressing member 128 projecting from the holding member 118 of the opening/closing mechanism 110 . As the operating rod connecting member 125 is further rotated in the forward direction, the hook portion 284 of the lock body 276 pushed by the lock body pressing member 128 rotates further inward (toward the center). 284 securely engages the lock body engaging member 280 .

さらに操作棒接続部材１２５を順方向に回していくと、図１６に示すように、フック部２８４が確実にロック本体係合部材２８０と係合した状態のままで回転機構２００が回転し、当該回転機構２００に取り付けられた皮剥機構３００による電線Ｌの皮剥ぎ作業が進んでいく。 As the operating rod connecting member 125 is further rotated in the forward direction, as shown in FIG. The work of stripping the wires L by the stripping mechanism 300 attached to the rotating mechanism 200 proceeds.

（回転機構２００に対する皮剥機構３００の着脱動作）
回転機構２００に対して皮剥機構３００を取り付ける場合は、回転機構２００の皮剥機構取付部材２０６における中央部の孔に皮剥機構３００の回転機構挿入端部３１４を差し込んでいき、皮剥機構取付部材２０６における一対の固定用溝２６８に皮剥機構３００の回転機構取付突部３１６を嵌め込むことによって完了する。 (Detachment operation of peeling mechanism 300 with respect to rotation mechanism 200)
When the peeling mechanism 300 is attached to the rotating mechanism 200, the rotating mechanism insertion end 314 of the peeling mechanism 300 is inserted into the center hole of the peeling mechanism attaching member 206 of the rotating mechanism 200, and the peeling mechanism attaching member 206 is inserted. The process is completed by fitting the rotation mechanism mounting projections 316 of the peeling mechanism 300 into the pair of fixing grooves 268 .

固定用溝２６８に回転機構取付突部３１６を嵌め込む際、皮剥機構３００の挿入孔挿通突部３１８を固定用溝２６８に設けられた挿入孔２６９に挿入していくが、このとき挿入孔挿通突部３１８の先端がテーパー状に面取りしてあれば、挿入孔挿通突部３１８を挿入していくにつれて当該挿入孔挿通突部３１８の先端に形成されたテーパー面が挿入孔２６９にかかるようになっている皮剥機構固定部材２４１の一端部２７４を回動付勢弾性部材２７５の弾性力に抗して外方に押しのけていく。そして、挿入孔挿通突部３１８を挿入孔２６９に対してさらに押し込んでいくと、皮剥機構固定部材２４１の一端部２７４が挿入孔挿通突部３１８の周溝３２０に嵌まることにより、回転機構２００に対する皮剥機構３００の取り付けが完了するとともに、皮剥機構３００が回転機構２００から不所望に外れてしまうことがなくなる。 When fitting the rotation mechanism mounting protrusion 316 into the fixing groove 268, the insertion hole insertion protrusion 318 of the peeling mechanism 300 is inserted into the insertion hole 269 provided in the fixing groove 268. At this time, the insertion hole is inserted. If the tip of the protrusion 318 is chamfered in a tapered shape, the tapered surface formed at the tip of the insertion hole insertion protrusion 318 is placed on the insertion hole 269 as the insertion hole insertion protrusion 318 is inserted. The one end portion 274 of the peeling mechanism fixing member 241 that has been turned is pushed outward against the elastic force of the rotation biasing elastic member 275 . When the insertion hole insertion protrusion 318 is further pushed into the insertion hole 269 , the one end 274 of the skin peeling mechanism fixing member 241 is fitted into the circumferential groove 320 of the insertion hole insertion protrusion 318 , thereby rotating the rotating mechanism 200 . When the attachment of the peeling mechanism 300 to the is completed, the peeling mechanism 300 is prevented from being undesirably detached from the rotating mechanism 200. - 特許庁

回転機構２００から皮剥機構３００を取り外す場合は、回動付勢弾性部材２７５の弾性力に抗して皮剥機構固定部材２４１の他端部を押し込んで、皮剥機構固定部材２４１の一端部２７４を挿入孔挿通突部３１８の周溝３２０（および挿入孔２６９）から離間させつつ、皮剥機構３００を回転機構２００から取り外すことになる。 When removing the peeling mechanism 300 from the rotating mechanism 200, the other end of the peeling mechanism fixing member 241 is pushed in against the elastic force of the rotation biasing elastic member 275, and one end 274 of the peeling mechanism fixing member 241 is inserted. The skin peeling mechanism 300 is removed from the rotation mechanism 200 while being separated from the circumferential groove 320 (and the insertion hole 269) of the hole insertion projection 318.

（実施形態に係る電線皮剥工具１００の特徴）
上述した実施形態に係る電線皮剥工具１００では、従来の電線皮剥工具と同じく切削機構３０４を電線Ｌに対して回転させる回転力を加えることにより、開閉ロック機構２０８を構成するロック本体２７６の外向突設部２８６の外面が開閉機構１１０の保持部材１１８に突設されたロック本体押圧部材１２８に当接する。さらに回転力を加えると、ロック本体押圧部材１２８に押圧されたロック本体２７６のフック部２８４がさらに内側（中心側）に向けて、つまり、ロック本体係合部材２８０に向けて回動することとなり、当該フック部２８４が確実にロック本体係合部材２８０と係合するようになる。 (Characteristics of the wire stripping tool 100 according to the embodiment)
In the wire stripping tool 100 according to the above-described embodiment, as in the conventional wire stripping tool, by applying a rotational force to rotate the cutting mechanism 304 with respect to the wire L, the lock body 276 constituting the open/close lock mechanism 208 protrudes outward. The outer surface of the provided portion 286 abuts on the lock body pressing member 128 projecting from the holding member 118 of the opening/closing mechanism 110 . When a further rotational force is applied, the hook portion 284 of the lock body 276 pressed by the lock body pressing member 128 rotates further inward (toward the center), that is, toward the lock body engaging member 280 . , the hook portion 284 is reliably engaged with the lock body engaging member 280 .

このように、上述した実施形態に係る電線皮剥工具１００によれば、回転力を加え続けるだけで回転機構２００を完全に閉じることができる。 Thus, according to the wire stripping tool 100 according to the embodiment described above, the rotation mechanism 200 can be completely closed simply by continuing to apply the rotation force.

また、上述した実施形態に係る電線皮剥工具１００では、回転機構２００に対して皮剥機構３００を取り付ける際、皮剥機構取付部材２０６における一対の固定用溝２６８に皮剥機構３００の回転機構取付突部３１６を嵌め込んでいき、皮剥機構３００の挿入孔挿通突部３１８を固定用溝２６８に設けられた挿入孔２６９に挿入していく。これにより、皮剥機構固定部材２４１の一端部２７４が挿入孔挿通突部３１８の周溝３２０に嵌まるので、回転機構２００に対する皮剥機構３００の取り付けが簡単に完了するとともに、皮剥機構３００が回転機構２００から不所望に外れてしまうことがなくなる。 Further, in the wire stripping tool 100 according to the above-described embodiment, when the stripping mechanism 300 is attached to the rotating mechanism 200, the rotating mechanism attachment projections 316 of the stripping mechanism 300 are fitted into the pair of fixing grooves 268 of the stripping mechanism attachment member 206. , and the insertion hole insertion projection 318 of the peeling mechanism 300 is inserted into the insertion hole 269 provided in the fixing groove 268 . As a result, one end portion 274 of the peeling mechanism fixing member 241 is fitted into the circumferential groove 320 of the insertion hole insertion protrusion 318, so that the attachment of the peeling mechanism 300 to the rotating mechanism 200 is easily completed, and the peeling mechanism 300 is connected to the rotating mechanism. Undesirably deviating from 200 is eliminated.

さらに、挿入孔挿通突部３１８の先端をテーパー状に面取りしておくことにより、挿入孔挿通突部３１８を挿入していくにつれて当該挿入孔挿通突部３１８の先端に形成されたテーパー面が挿入孔２６９にかかるようになっている皮剥機構固定部材２４１の一端部２７４を回動付勢弾性部材２７５の弾性力に抗して外方に押しのけていく。そして、挿入孔挿通突部３１８を挿入孔２６９に対してさらに押し込んでいくと、皮剥機構固定部材２４１の一端部２７４が挿入孔挿通突部３１８の周溝３２０に嵌まることにより、回転機構２００に対する皮剥機構３００の取り付けをワンタッチで簡単に実施することができる。 Furthermore, by chamfering the tip of the insertion hole insertion protrusion 318 in a tapered shape, the tapered surface formed at the tip of the insertion hole insertion protrusion 318 is inserted as the insertion hole insertion protrusion 318 is inserted. The one end 274 of the peeling mechanism fixing member 241 that is placed over the hole 269 is pushed outward against the elastic force of the rotationally biasing elastic member 275 . When the insertion hole insertion protrusion 318 is further pushed into the insertion hole 269 , the one end 274 of the skin peeling mechanism fixing member 241 is fitted into the circumferential groove 320 of the insertion hole insertion protrusion 318 , thereby rotating the rotating mechanism 200 . The attachment of the peeling mechanism 300 can be easily carried out with one touch.
