本考案は、被覆電線ストリッパーに係わり、電線表皮の絶縁ビニール等を電線 芯部ワイヤーを損傷することなく能率的に剥取ることのできる被覆電線ストリッ パーに関する。 The present invention relates to a covered electric wire stripper, and relates to a covered electric wire stripper capable of efficiently stripping an insulating vinyl or the like on an electric wire skin without damaging a wire core wire.
【０００２】[0002]
被覆電線の絶縁ビニール等の電線表皮を剥取る作業は、能率性と共に電線芯部 ワイヤーを損傷することなく行なうことが要求される。しかし乍ら、かかる作業 に使用される従来の工具は、一般に電線芯部ワイヤーの損傷防止手段を施したも のはみられず、また能率性の向上を意図した工夫も特になされていなかった。 It is required that the work of stripping the insulation skin such as the insulation vinyl of the covered electric wire be performed efficiently and without damaging the wire core. However, the conventional tools used for such work generally do not have any means for preventing damage to the core wire of the electric wire, and no special measures for improving efficiency have been made.
【０００３】 このため熟練の作業員が専ら永年の経験と勘にもとずく手感によって電線芯部 ワイヤーを損傷しないように充分に注意し乍ら作業を行なうのが常であった。し かし能率上の問題と共に電線芯部ワイヤーの損傷防止も必ずしも充分でなく、更 に熟練の作業員を要すると言う問題点があった。For this reason, it has been customary for a skilled worker to carry out the work while paying sufficient attention not to damage the core wire of the electric wire by the hand sensation based on his long experience and intuition. However, in addition to the problem of efficiency, the prevention of damage to the core wire of the electric wire is not always sufficient, and there is a problem that more skilled workers are required.
【０００４】 これらに対処して、本願出願人は、電線芯部ワイヤーの損傷防止手段を施すと 共に電線表皮の剥取り機構を具備した被覆電線ストリッパーを先にも提案した（ 平成２年実用新案登録願第１０９７３２号）。In response to these problems, the applicant of the present application previously proposed a covered electric wire stripper equipped with a mechanism for preventing damage to the electric wire core wire and also having a mechanism for stripping the electric wire skin (Practical model in 1990. Registration application No. 109732).
【０００５】[0005]
しかし乍ら、上記の被覆電線ストリッパーを用いて行なう電線表皮の剥取り作 業において、被覆電線の電線表皮を円周方向に切込もうとすると被覆電線をスト リッパーの外側に押し出す応力が働き、被覆電線がストリッパーから摺脱する現 象がみられ、このため作業が必ずしも容易でないと言う問題が見出された。 However, in the stripping operation of the electric wire skin using the above-mentioned covered electric wire stripper, when attempting to cut the electric wire skin of the covered electric wire in the circumferential direction, the stress of pushing the covered electric wire to the outside of the stripper acts, There was a phenomenon that the covered electric wire slid off from the stripper, and a problem was found that the work was not always easy.
【０００６】 また、電線表皮の剥取り作業工程のうち、一部工程が工具を使用せず、直接手 で行なう作業のために、能率上問題があることが判明した。Further, it has been found that there is a problem in efficiency because some of the steps of stripping the electric wire skin are performed directly by hand without using a tool.
【０００７】 本考案は、かかる問題点に対処してなされたものであり、その目的とするとこ ろは、作業中に電線芯部ワイヤーの損傷を防止しながら被覆電線がストリッパー から摺脱する現象を防止して作業の容易性を図ると共に、ストリッパーを改良し て、従来、直接手で行なっていた作業を工具を用いて行なうことを可能にし、こ れにより、作業能率が高度に優れる被覆電線ストリッパーを提供するものである 。The present invention has been made to address such a problem, and its purpose is to prevent a covered wire from sliding off from a stripper while preventing damage to the wire core wire during work. In addition to preventing the above-mentioned problems and improving the workability, the stripper has been improved so that the work that was previously done directly by hand can be done with a tool, which makes it possible to achieve high work efficiency. It provides a stripper.

It is provided inside.
【００１９】 図５は、図４におけるＢ−Ｂ端面図である。FIG. 5 is a BB end view in FIG.
【００２０】 切込深さ調節具５ａ，５ｂの切込深さ調節ライン部５−１ａ，５−１ｂ即ち切 込深さ調節具５ａ，５ｂの端面のうち表皮切込部４を構成する凹状刃４−１ａ， ４−１ｂの刃先に面する端面によって形成されるライン部５−１ａ，５−１ｂ（ 図１においては実線で示されるが、図４においては、主たる部分が凹状刃４−１ ａ，４−１ｂの裏側に破線で示される）が、凹状刃４−１ａ，４−１ｂの凹状曲 線に沿って設けられるとは、切込深さ調節ライン部５−１ａ，５−１ｂの曲率が 凹状刃４−１ａ，４−１ｂの曲率とほぼ同一に形成される即ち凹状刃４−１ａ， ４−１ｂの刃先から切込深さ調節ライン部５−１ａ，５−１ｂに至る長さ（図４ に符号Ｌ２で示す）がいずれの箇所においてもほぼ一定であることを意味する。 このように構成することにより、電線表皮の円周方向切込深さをほぼ一定とする ことができる。The cut depth adjusting line portions 5-1a and 5-1b of the cut depth adjusting tools 5a and 5b, that is, the concave shape that constitutes the skin cut portion 4 on the end surfaces of the cut depth adjusting tools 5a and 5b. Line portions 5-1a and 5-1b formed by the end surfaces of the blades 4-1a and 4-1b facing the blade tip (indicated by solid lines in FIG. 1, but in FIG. 4, the main portion is a concave blade 4-). 1a, 4-1b), which is indicated by a broken line on the back side of 1a, 4-1b, is provided along the concave curved line of the concave blades 4-1a, 4-1b. The curvature of 1b is formed to be substantially the same as that of the concave blades 4-1a and 4-1b, that is, from the cutting edge of the concave blades 4-1a and 4-1b to the cutting depth adjustment line portions 5-1a and 5-1b. This means that the length (indicated by symbol L2 in FIG. 4) is almost constant at any point. With this configuration, the circumferential cut depth of the electric wire skin can be made substantially constant.
【００２１】 なお、本明細書においては、凹状刃４−１ａ，４−１ｂの凹状曲線に沿って設 けられていない部分は、切込深さ調節ライン部５−１ａ，５−１ｂとは称さない 。In the present specification, the portions of the concave blades 4-1a and 4-1b that are not provided along the concave curve are referred to as the cutting depth adjustment line portions 5-1a and 5-1b. Don't call.
【００２２】 本考案の最大の特徴は、切込深さ調節ライン部５−１ａ，５−１ｂの剥取部側 先端５−１Ａ，５−１Ｂ（凹状刃４−１ａ，４−１ｂの凹状曲線に沿って設けら れた切込深さ調節ライン部５−１ａ，５−１ｂの剥取部３側に位置する先端部分 ）が、凹状刃４−１ａ，４−１ｂの凹状曲線の剥取部側先端４−１Ａ，４−１Ｂ を越えて延設されていることである。The greatest feature of the present invention is that the cutting depth adjusting line parts 5-1a and 5-1b are on the peeling side and the tips 5-1A and 5-1B (the concave shape of the concave blades 4-1a and 4-1b). The tip portion located on the peeling portion 3 side of the cutting depth adjusting line portions 5-1a and 5-1b provided along the curved line is the peeling of the concave curved line of the concave blades 4-1a and 4-1b. That is, it extends beyond the leading ends 4-1A and 4-1B.
【００２３】 このように延設される結果として、切込深さ調節ライン部５−１ａ，５−１ｂ の剥取部側先端５−１Ａ，５−１Ｂは凹状刃４−１ａ，４−１ｂの凹状曲線の剥 取部側先端４−１Ａ，４−１Ｂよりも剥取部３側に位置すると共に、多くの場合 対設された２つの凹状刃４−１ａ，４−１ｂの凹状曲線の剥取部側先端４−１Ａ ，４−１Ｂ間の間隙寸法よりも、対設された２つの切込深さ調節ライン部５−１ ａ，５−１ｂの剥取部側先端５−１Ａ，５−１Ｂ間の間隙寸法が小さくなる。As a result of being extended in this way, the tip ends 5-1A and 5-1B of the cutting depth adjustment line portions 5-1a and 5-1b are concave blades 4-1a and 4-1b. Of the concave curve of the two concave blades 4-1a, 4-1b which are located closer to the peeling section 3 side than the exfoliation section-side tips 4-1A, 4-1B of the concave curve of FIG. The peeling-section-side tips 5-1A and 5-1b of the two cutting depth adjustment line portions 5-1a and 5-1b arranged opposite to each other are larger than the gap between the peeling-section-side tips 4-1A and 4-1B. The gap size between 5-1B becomes small.
【００２４】 このために、凹状刃の凹状曲線の剥取部側先端４−１Ａ，４−１Ｂを越えて延 設された切込深さ調節ライン部分が、電線表皮の剥取り作業中に前記した被覆電 線がストリッパーから摺脱しようとする現象に対してストッパーとして作用し、 被覆電線を確実に抱き込むことができ凹状刃４−１ａ，４−１ｂによる電線表皮 の円周方向切込の作業性が良好となる。 一般に、かかる摺脱現象の防止は、凹状刃に付設され対設された切込深さ調節 具（５ａ，５ｂ）の剥取部（３）側の間隙寸法が、対設された凹状刃（４−１ａ ，４−１ｂ）の剥取部（３）側の間隙寸法よりも小さく構成されることによって 達成される。即ち、切込深さ調節ライン部の剥取部側先端部分に限らず、切込深 さ調節具の剥取部側のいずれかの部分の間隙寸法が、対設された凹状刃の剥取部 側の最小間隙寸法よりも小さく構成されていてもよい。本考案は、かかる考案も 提供する。For this reason, the cutting depth adjustment line portion extending beyond the exfoliation portion side tips 4-1A and 4-1B of the concave curve of the concave blade is used during the stripping operation of the electric wire skin during the stripping operation. The covered wire acts as a stopper against the phenomenon that it tries to slide out from the stripper, and the covered wire can be held securely, and the concave blades 4-1a and 4-1b can cut the outer surface of the wire in the circumferential direction. Good workability. Generally, such a sliding-off phenomenon is prevented by setting the gap dimension on the peeling portion (3) side of the cutting depth adjusting tools (5a, 5b) attached to and opposite to the concave blade to the concave blade ( This is achieved by making the gap size of 4-1a, 4-1b) smaller on the side of the stripping portion (3). That is, not only the tip of the cutting depth adjusting line on the peeling side, but the gap size of any part of the cutting depth adjusting tool on the peeling side is the peeling of the concave blade that is placed opposite. It may be configured to be smaller than the minimum gap size on the part side. The present invention also provides such a device.
【００２５】 また、電線芯部ワイヤーが細い素線で構成された被覆電線は極めて不定形即ち 弱い外部応力に対しても変形し易く、かかる不定形な被覆電線の表皮の円周方向 切込作業は、被覆電線を切込深さ調節ライン部上を摺動乃至転動させ乍ら凹状刃 で切込むのが作業を容易にし良好な結果が得られるが、切込深さ調節ライン部５ −１ａ，５−１ｂを前記のように延設することにより、該切込深さ調節ライン部 が比較的長寸法となり連続性が得られ、上記の不定形な被覆電線の円周方向切込 作業が容易となる。Further, the covered electric wire in which the core wire of the electric wire is made of a thin wire is extremely indefinite, that is, it is easily deformed by a weak external stress, and the work of cutting the skin of the indefinite covered wire in the circumferential direction is performed. For sliding the coated wire on the depth of cut adjustment line or rolling it and cutting it with a concave blade facilitates the work and obtains good results, but the depth of cut adjustment line 5- By extending 1a and 5-1b as described above, the cutting depth adjusting line portion becomes a relatively long dimension and continuity can be obtained, and the above-mentioned irregular shape coated wire circumferential cutting operation Will be easier.
【００２６】 また、本考案は、剥取部３の対設された刃部３ａと廻り止め部３ｂの両者の先 端部間の間隙寸法（図１において符号Ｌ３で示す）が、被覆電線ストリッパーの 閉口時において、２ｍｍ以下好しくは１〜１．５ｍｍ程度に構成することも提案 する。Further, according to the present invention, the gap size (indicated by symbol L3 in FIG. 1) between the front end portions of both the blade portion 3a and the rotation stop portion 3b of the stripping portion 3 which are provided opposite to each other is such that the covered wire stripper It is also proposed to configure it to be 2 mm or less, preferably about 1 to 1.5 mm when closed.
【００２７】 前記したように、剥取部３を有するストリッパーは、本願出願人が平成２年実 用新案登録願第１０９７３２号として初めて提案したものであるが、該提案にお いては、剥取部の対設された刃部と廻り止め部の両者の先端部間の間隙寸法は、 １０ｍｍ近く或はそれ以上に大きいものであった。As described above, the stripper having the stripping portion 3 was first proposed by the applicant of the present application as a utility model registration application No. 109732 in 1990. In the proposal, stripping is performed. The gap between the tips of both the blade and the rotation-stopping part of the section was close to 10 mm or more.
【００２８】 該間隙寸法を２ｍｍ以下と構成することは、本考案によって初めて提案される ものであるが、その効果を説明する前に、まず本考案の被覆電線ストリッパーを 用いて作業を行なう工程を説明する。It is the first proposal of the present invention to configure the gap size to be 2 mm or less, but before explaining the effect, first, the step of performing work using the covered wire stripper of the present invention is described. explain.
【００２９】 図６は、被覆電線の長さ方向に垂直な断面図、図７は被覆電線の斜視図を夫々 示す。FIG. 6 is a sectional view perpendicular to the length direction of the covered electric wire, and FIG. 7 is a perspective view of the covered electric wire.
【００３０】 電線表皮９の絶縁ビニール等の剥取り作業を行なう場合、まず所望とする切込 み深さを切込深さ調節具５ａ，５ｂで調節した後に、表皮切込部４を利用して電 線表皮８を電線の円周方向に切込む。なお、図７において円周方向切込み位置を 符号Ｔで示す。When removing the insulating vinyl or the like from the electric wire skin 9, first adjust the desired cutting depth with the cutting depth adjusters 5a and 5b, and then use the skin cutting portion 4. Cut the wire skin 8 in the circumferential direction of the wire. Note that, in FIG. 7, a circumferential cut position is indicated by a symbol T.
【００３１】 この場合、前記したように不定形な被覆電線の場合は、被覆電線を切込深さ調 節ライン部上を摺動又は転動させ乍ら行なうのが好しく、また電線表皮９が硬い 場合は、円周方向に数回に分割して切込みを行なう方が良好である。In this case, as described above, in the case of an irregularly shaped covered electric wire, it is preferable that the covered electric wire be slid or rolled on the cut depth adjustment line portion, and the electric wire skin 9 If is hard, it is better to cut it in several times in the circumferential direction.
【００３２】 切込深さ調節具５ａ，５ｂによって切込深さを調節するには、該切込深さ調節 具を所望とする切込深さに適合するものと取換えてもよいが、切込深さ調節具の ビス止め孔を例えばスリット状のものとし、所望とする位置でビス止めすること によって調節することもできる。In order to adjust the depth of cut by the depth of cut adjusting tools 5a and 5b, the depth of cut adjusting tool may be replaced with one that fits the desired depth of cut. It is also possible to adjust the cutting depth adjusting tool by, for example, forming a slit-shaped hole for fixing the screw and fixing the screw at a desired position.
【００３３】 電線表皮９を電線の円周方向に切込んだ後に、電線表皮の符号Ｍで示す部分に 剥取部３の刃部３ａの先端を、また符号Ｎで示す部分に廻り止め部３ｂの先端を 夫々当てがって、被覆電線を噛み、次いで符号Ｍの部分の電線表皮を切割ると共 に、本考案のストリッパーを符号Ｎで示す部分を回転軸として回転させて電線表 皮９を電線芯部ワイヤー８から剥離させる。After the electric wire skin 9 is cut in the circumferential direction of the electric wire, the tip of the blade portion 3a of the peeling portion 3 is located at a portion indicated by the symbol M of the electric wire skin, and the rotation stopping portion 3b is located at a portion indicated by the symbol N. Apply the tip of each of them to bite the covered electric wire, and then cut the electric wire skin of the portion M, and at the same time, rotate the stripper of the present invention with the portion N as the rotation axis to rotate the electric wire 9 Is separated from the wire core wire 8.
【００３４】 本願出願人が先に提案したストリッパーの場合は、該ストリッパーを利用した 作業は、この電線表皮を電線芯部ワイヤーから剥離させる段階までであった。そ の後は、該剥離された電線表皮を直接、手で掴み引張って電線芯部ワイヤーから 剥取ることが行なわれていた。しかし乍ら、かかる電線表皮を直接、手で掴み剥 取る作業は、指先に力を集中させることを要し、疲労し易く長時間の作業を困難 にし作業能率を低下させる一因となっていた。In the case of the stripper previously proposed by the applicant of the present application, the work using the stripper was up to the step of peeling the electric wire skin from the electric wire core wire. After that, the peeled electric wire skin was directly grasped by a hand and pulled to peel off the electric wire core wire. However, the work of directly gripping and peeling off the electric wire skin by hand requires concentration of force on the fingertips, which easily causes fatigue and makes long-term work difficult, which is one of the causes of lowering work efficiency. .
【００３５】 このため本考案のストリッパーにおいては、剥取部３の対設された刃部３ａと 廻り止め部３ｂの両者の先端部間の間隙寸法を、先に提案したストリッパーでは 、１０ｍｍ近く或はそれ以上あったものを２ｍｍ以下に構成することにより、剥 離された電線表皮を該刃部と廻り止め部の両者の先端間で挟持して掴み電線芯部 ワイヤーから剥取ることを可能にした。Therefore, in the stripper of the present invention, the gap size between the tip portions of the blade portion 3a and the anti-rotation portion 3b of the stripping portion 3 which face each other is about 10 mm or less in the previously proposed stripper. By configuring what has been more than 2 mm or less, it is possible to pinch the peeled wire skin between the tips of both the blade and the rotation prevention part and grab it from the wire core wire. did.
【００３６】 即ち、本考案においては、被覆電線の電線表皮の円周方向切込み作業性を良好 にすると共に、次工程としての被覆電線の長さ方向における噛む、切割る、掴む 及び剥取るの一連の全工程をストリッパーを用いて行なうことが可能となり、こ のため作業に要する握力エネルギーをストリッパーの工具を介して効果的に利用 することができ作業能率を大幅に向上させることができる。That is, in the present invention, the work of circumferentially cutting the electric wire skin of the covered electric wire is improved, and a series of biting, cutting, gripping and peeling in the longitudinal direction of the covered electric wire is performed as the next step. It is possible to perform all of the steps using the stripper, and therefore the gripping energy required for the work can be effectively utilized via the tool of the stripper, and the work efficiency can be greatly improved.
【００３７】 なお、図６において、右側の電線表皮を剥取った後に、左側の電線表皮も剥取 るが、通常は既に円周方向の切込みがなされているために、該左側の電線表皮の 剥取りは、剥取部の刃部と廻り止め部の両者の先端間で掴み容易に剥取ることが できる。In FIG. 6, after the right-side wire skin is peeled off, the left-side wire skin is also peeled off. However, since the circumferential notch is usually made, the left-side wire skin is cut off. Peeling can be easily done by grasping between the tips of both the blade of the peeling section and the rotation stopping section.
【００３８】 剥取部の刃部と廻り止め部の両者の先端部間の間隙寸法の微調整は、図１にお いて連結部２に関して表皮切込部４と反対側の腕体対向部に、腕体間の閉度を調 節する腕体閉度調節部６を設けて行なう態様が好しく採用される。Fine adjustment of the gap dimension between the tip of the blade of the stripping section and the tip of the anti-rotation section is performed in the arm body facing section on the side opposite to the skin cut section 4 with respect to the connecting section 2 in FIG. A mode in which the arm closed degree adjusting unit 6 for adjusting the closeness between the arms is provided is preferably adopted.
【００３９】 腕体閉度調節部６としては、腕体間の閉度を調節できる機構のものであれば特 に限定されないが、簡単な構造のものとしては図１に示すように一方の腕体の他 方の腕体に対向する面上にボルトを立設して、立設寸法の長さを調節することに より腕体の閉度の下限を律する態様のものがあげられる。また、ボルトにナット を併用することによりボルトの立設寸法の安定性が良好となる。The arm closed degree adjusting unit 6 is not particularly limited as long as it has a mechanism capable of adjusting the closed degree between the arms, but a simple structure has one arm as shown in FIG. There is an embodiment in which a lower limit of the degree of closure of the arm is regulated by arranging a bolt on the surface of the other body facing the arm and adjusting the length of the erected size. In addition, the stability of the upright dimension of the bolt is improved by using the nut together with the bolt.
【００４０】 なお、被覆電線の剥取る寸法長は、一般に電線の太さと関連する場合が多く、 例えば本考案ストリッパーの腕体の一部に電線の太さと剥取る寸法長の目安スケ ールを付設する態様も好しく採用される。In general, the stripped dimension of the covered electric wire is often related to the thickness of the electrical wire. For example, a guideline for the stripped wire and the stripped dimension length is attached to a part of the arm of the stripper of the present invention. The attached mode is also preferably adopted.

以上説明したように、本考案は、切込深さ調節具の切込深さ調節ライン部が凹 状刃の凹状曲線に沿って設けられているために、凹状刃の刃先から切込深さ調節 ライン部に至る距離がほぼ一定となり、電線表皮の円周方向切込深さをほぼ一定 とすることができ、電線芯部ワイヤーの損傷を防止することができる。 As described above, according to the present invention, since the cutting depth adjustment line portion of the cutting depth adjuster is provided along the concave curve of the concave blade, the cutting depth from the cutting edge of the concave blade is cut. Since the distance to the adjustment line portion becomes almost constant, the depth of cut in the circumferential direction of the electric wire skin can be made substantially constant, and damage to the wire core wire can be prevented.
【００４２】 また、切込深さ調節ライン部の剥取部側先端が凹状刃の凹状曲線の剥取部側先 端を越えて延設されているために、該延設部分が剥取り作業中において被覆電線 のストッパーとして作用し、被覆電線を確実に抱き込むことができ、凹状刃によ る電線表皮の円周方向切込が容易となると共に不定形な被覆電線を切込深さ調節 ライン部上を摺動又は転動させながら円周方向切込を行なう際に該切込深さ調節 ライン部の連続した長寸法が得られ作業性が優れて良好になる。 この点、一般に凹状刃に付設され対設された切込深さ調節具の剥取部側の間隙 寸法が、対設された凹状刃の剥取部側の間隙寸法よりも小さく構成されている場 合も同様である。。Further, since the tip of the cutting depth adjusting line portion on the peeling portion side extends beyond the tip of the concave curve of the concave blade on the peeling portion side, the extended portion is peeled off. It acts as a stopper for the covered electric wire inside and can securely wrap the covered electric wire, making it easy to cut the electric wire skin in the circumferential direction with a concave blade and adjusting the cutting depth for irregular shaped electric wires. When making a circumferential cut while sliding or rolling on the line portion, the continuous depth of the cut depth adjusting line portion can be obtained, and the workability is excellent and good. In this regard, generally, the gap size on the peeling portion side of the cutting depth adjuster provided opposite to the concave blade is configured to be smaller than the gap dimension on the peeling portion side of the facing concave blade. The same applies in the case. .
【００４３】 また、剥取部の対設された刃部と廻り止め部の両者の先端部間の間隙寸法が、 被覆電線ストリッパーの閉口時において、２ｍｍ以下に構成されているために、 刃部と廻り止め部によって、電線表皮を切割りした後に、該刃部と廻り止め部の 先端間で電線表皮を容易に挟持して掴み剥取ることができる。In addition, the gap between the tip of the blade and the anti-rotation part of the stripping part, which are arranged opposite to each other, is 2 mm or less when the covered electric wire stripper is closed. The electric wire skin can be easily sandwiched between the blade portion and the tip of the whirl-stop portion after the electric wire skin has been cut by the whirl-stop portion.
【００４４】 このように、本考案は、電線芯部ワイヤーの損傷を防止しながら被覆電線の電 線表皮の円周方向切込みの作業性を良好にすると共に、次工程としての被覆電線 の長さ方向における噛む、切割る、掴む及び剥取るの一連の全工程をストリッパ ーの工具を用いて行なうことを可能にしたものであり、作業能率を大幅に向上さ せることができる。As described above, according to the present invention, the workability of the circumferential cut of the electric wire skin of the covered electric wire is improved while the damage of the electric wire core wire is prevented, and the length of the covered electric wire as the next step is improved. This makes it possible to perform all the steps of biting, cutting, grasping and peeling in the direction using the tool of the stripper, and it is possible to greatly improve the work efficiency.
