Description
本発明は、線状の導体が絶縁被覆層で被覆されてなるワイヤの絶縁被覆層の一部を除去する際に用いられるワイヤストリッパに関する。 The present invention relates to a wire stripper used for removing a part of an insulating coating layer of a wire in which a linear conductor is coated with an insulating coating layer.
各種配線等に使用されるワイヤ（電線）は、例えば、線状の導体を絶縁被覆層で被覆することにより形成されている。そのため、ワイヤを端子等に接続する際には、絶縁被覆層の一部を除去して導体を露出させる必要がある。この作業には、例えば、絶縁被覆層の切断及び除去に適したワイヤストリッパと呼ばれる工具が用いられる（例えば、特許文献１及び特許文献２参照）。 Wires (electric wires) used for various wirings and the like are formed by, for example, covering a linear conductor with an insulating coating layer. Therefore, when connecting the wire to the terminal or the like, it is necessary to remove a part of the insulating coating layer to expose the conductor. For this work, for example, a tool called a wire stripper suitable for cutting and removing the insulating coating layer is used (see, for example, Patent Document 1 and Patent Document 2).
ところで、上述のワイヤストリッパで絶縁被覆層を切断する際には、ワイヤに対するワイヤストリッパの刃の位置を作業者の直感に基づいて決めることがある。しかしながら、この方法では、必ずしも絶縁被覆層を適切な位置で切断できなかった。ワイヤの長さを測定して刃を当てる位置に目印等を付せば、この問題を解消できるが、長さを測定して目印等を付すという手間が増えるので、作業の効率は低下してしまう。 By the way, when cutting the insulating coating layer with the above-mentioned wire stripper, the position of the blade of the wire stripper with respect to the wire may be determined based on the intuition of the operator. However, this method could not always cut the insulating coating layer at an appropriate position. This problem can be solved by measuring the length of the wire and marking the position where the blade is applied, but the labor of measuring the length and marking the position increases, so the work efficiency decreases. It ends up.
本発明はかかる問題点に鑑みてなされたものであり、その目的とするところは、ワイヤの絶縁被覆層を簡単かつ適切に切断できるワイヤストリッパを提供することである。 The present invention has been made in view of such problems, and an object of the present invention is to provide a wire stripper capable of easily and appropriately cutting an insulating coating layer of a wire.
本発明の一態様によれば、線状の導体と該導体を被覆する絶縁被覆層とからなるワイヤの該絶縁被覆層を切断する際に用いられるワイヤストリッパであって、開閉可能な一対の刃部を有する切断ユニットと、該刃部に対して接触する接触面を含み磁力で該刃部に固定される固定部と、該ワイヤの端部が突き当てられる突き当て面を含み該突き当て面に該ワイヤの端部が突き当てられることで該絶縁被覆層が該刃部によって切断される切断位置を規定する突き当て部と、を有する切断位置規定ユニットと、を備え、該突き当て部は、該接触面からの距離が異なる複数の該突き当て面を含むことを特徴とするワイヤストリッパが提供される。 According to one aspect of the present invention, a wire stripper used for cutting the insulating coating layer of a wire composed of a linear conductor and an insulating coating layer covering the conductor, and a pair of openable and closable blades. The abutting surface includes a cutting unit having a portion, a fixing portion including a contact surface in contact with the blade portion and fixed to the blade portion by magnetic force, and an abutting surface to which the end portion of the wire is abutted. The abutting portion comprises a cutting position defining unit having a abutting portion that defines a cutting position in which the insulating coating layer is cut by the blade portion by abutting the end portion of the wire. A wire stripper is provided that includes a plurality of the abutting surfaces having different distances from the contact surface.
本発明の一態様において、該突き当て部は、環状に配列された複数の該突き当て面を含み、複数の該突き当て面が配列する方向に沿って回転できるように該固定部に連結され、該突き当て部を該固定部に対して回転させることにより、使用される該突き当て面が選択されても良い。 In one aspect of the present invention, the abutting portion includes a plurality of the abutting surfaces arranged in an annular shape, and is connected to the abutting portion so as to be rotatable along a direction in which the abutting surfaces are arranged. The abutting surface to be used may be selected by rotating the abutting portion with respect to the fixing portion.
本発明の一態様において、該切断位置規定ユニットは、該突き当て面として機能する表面と該表面とは反対側の裏面とを有し該突き当て部に対して着脱できるように構成された補助プレートを更に備え、該補助プレートが該突き当て部に装着されることで、該補助プレートの該表面と該裏面との距離に応じた該切断位置が設定されても良い。 In one aspect of the present invention, the cutting position defining unit has a front surface functioning as the abutting surface and a back surface opposite to the abutting surface, and is configured to be detachable from the abutting portion. By further providing a plate and mounting the auxiliary plate on the abutting portion, the cutting position may be set according to the distance between the front surface and the back surface of the auxiliary plate.
本発明の一態様にかかるワイヤストリッパは、磁力で刃部に固定される固定部と、ワイヤの端部が突き当てられる突き当て面を含む突き当て部と、を有する切断位置規定ユニットを備えている。よって、突き当て面にワイヤの端部を突き当てれば、この切断位置規定ユニットによって規定される切断位置で絶縁被覆層を切断できる。つまり、作業者の直感に基づいて切断位置を決める必要がなく、また、切断位置に目印等を付す必要もない。よって、絶縁被覆層を簡単かつ適切に切断できる。 A wire stripper according to an aspect of the present invention includes a cutting position defining unit having a fixing portion fixed to a blade portion by a magnetic force and an abutting portion including an abutting surface to which an end portion of the wire is abutted. There is. Therefore, if the end portion of the wire is abutted against the abutting surface, the insulating coating layer can be cut at the cutting position defined by the cutting position defining unit. That is, it is not necessary to determine the cutting position based on the intuition of the operator, and it is not necessary to put a mark or the like on the cutting position. Therefore, the insulating coating layer can be easily and appropriately cut.
添付図面を参照して、本発明の実施形態について説明する。図１は、本実施形態にかかるワイヤストリッパ２を構成する切断ユニット２ａの構造を模式的に示す斜視図であり、図２は、ワイヤストリッパ２を構成する切断位置規定ユニット２ｂの構造を模式的に示す斜視図である。図１及び図２に示すように、ワイヤストリッパ２は、切断ユニット２ａと、この切断ユニット２ａに装着される切断位置規定ユニット２ｂと、を備えている。 Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view schematically showing the structure of the cutting unit 2a constituting the wire stripper 2 according to the present embodiment, and FIG. 2 is a schematic view of the structure of the cutting position defining unit 2b constituting the wire stripper 2. It is a perspective view shown in. As shown in FIGS. 1 and 2, the wire stripper 2 includes a cutting unit 2a and a cutting position defining unit 2b mounted on the cutting unit 2a.
切断ユニット２ａは、例えば、所定の方向に長い第１部材６と第２部材８とを有する。第１部材６と第２部材８とは、鉄等の強磁性体を用いて形成されている。第１部材６の基端側（一端側）には、作業者によって把持される把持部６ａが設けられている。一方で、第１部材６の先端側（他端側）は、後述するワイヤ（電線）１（図４参照）の絶縁被覆層１ｂ（図４参照）を切断するための刃部６ｂになっている。 The cutting unit 2a has, for example, a first member 6 and a second member 8 that are long in a predetermined direction. The first member 6 and the second member 8 are formed by using a ferromagnetic material such as iron. A grip portion 6a gripped by an operator is provided on the base end side (one end side) of the first member 6. On the other hand, the tip end side (other end side) of the first member 6 is a blade portion 6b for cutting the insulating coating layer 1b (see FIG. 4) of the wire (electric wire) 1 (see FIG. 4) described later. There is.
第２部材８の構造は、第１部材６の構造に類似している。すなわち、第２部材８の基端側（一端側）には、作業者によって把持される把持部８ａが設けられている。また、第２部材８の先端側（他端側）は、ワイヤ１の絶縁被覆層１ｂを切断するための刃部８ｂになっている。 The structure of the second member 8 is similar to the structure of the first member 6. That is, a grip portion 8a gripped by an operator is provided on the base end side (one end side) of the second member 8. Further, the tip end side (the other end side) of the second member 8 is a blade portion 8b for cutting the insulating coating layer 1b of the wire 1.
第１部材６と第２部材８とは、一対の刃部６ｂ，８ｂを開閉できるように連結部材１０によって連結されている。具体的には、連結部材１０は、第１部材６と第２部材８とが交差するように、把持部６ａ，８ａと刃部６ｂ，８ｂとの間の位置で第１部材６と第２部材８とを連結している。 The first member 6 and the second member 8 are connected by a connecting member 10 so that the pair of blade portions 6b and 8b can be opened and closed. Specifically, the connecting member 10 has the first member 6 and the second member 6 at a position between the grip portions 6a and 8a and the blade portions 6b and 8b so that the first member 6 and the second member 8 intersect. It is connected to the member 8.
よって、把持部６ａと把持部８ａとを把持して閉じることで、一対の刃部６ｂ，８ｂを閉じることができる。一方で、連結部材１０の把持部６ａ，８ａ側には、把持部６ａ，８ａに対して開く方向の力を付与する圧縮コイルばね等の付勢部材１２が設けられている。そのため、把持部６ａ，８ａを把持する力を弱めると、把持部６ａと把持部８ａとは、付勢部材１２から作用する力によって開く。つまり、把持部６ａ，８ａを把持する力を弱めることで、一対の刃部６ｂ，８ｂを開くことができる。 Therefore, the pair of blade portions 6b and 8b can be closed by gripping and closing the grip portion 6a and the grip portion 8a. On the other hand, on the grip portion 6a, 8a side of the connecting member 10, an urging member 12 such as a compression coil spring that applies a force in the opening direction to the grip portion 6a, 8a is provided. Therefore, when the force for gripping the grip portions 6a and 8a is weakened, the grip portion 6a and the grip portion 8a are opened by the force acting from the urging member 12. That is, the pair of blade portions 6b, 8b can be opened by weakening the force for gripping the grip portions 6a, 8a.
刃部６ｂの内側（刃部６ｂの刃部８ｂ側）には、径の異なる複数の半円状の刃６ｃが設けられている。また、刃部８ｂの内側（刃部８ｂの刃部６ｂ側）には、刃６ｃに対応する複数の半円状の刃８ｃが設けられている。ワイヤ１の絶縁被覆層１ｂを、ワイヤ１の導体１ａ（図４参照）に対応する径の刃６ｃ，８ｃに接触させて、一対の刃部６ｂ，８ｂを閉じることで、導体１ａを切断することなく絶縁被覆層１ｂを切断できる。 A plurality of semicircular blades 6c having different diameters are provided inside the blade portion 6b (on the blade portion 8b side of the blade portion 6b). Further, a plurality of semicircular blades 8c corresponding to the blade 6c are provided inside the blade 8b (on the side of the blade 8b on the blade 6b side). The insulating coating layer 1b of the wire 1 is brought into contact with the blades 6c and 8c having a diameter corresponding to the conductor 1a of the wire 1 (see FIG. 4), and the pair of blade portions 6b and 8b are closed to cut the conductor 1a. The insulating coating layer 1b can be cut without any need.
刃部６ｂの側面には、図２に示す切断位置規定ユニット２ｂが装着される。この切断位置規定ユニット２ｂは、切断ユニット２ａの刃部６ｂに対して固定される固定部１４を有している。固定部１４は、例えば、第１方向Ｄ１に平行な辺を持つ直方体状の基部１４ａと、第１方向Ｄ１に対して概ね垂直な第２方向Ｄ２に平行な辺を持つ直方体状の支持部１４ｂと、を含む。 The cutting position defining unit 2b shown in FIG. 2 is mounted on the side surface of the blade portion 6b. The cutting position defining unit 2b has a fixing portion 14 fixed to the blade portion 6b of the cutting unit 2a. The fixed portion 14 is, for example, a rectangular parallelepiped base portion 14a having a side parallel to the first direction D1 and a rectangular parallelepiped support portion 14b having a side parallel to the second direction D2 substantially perpendicular to the first direction D1. And, including.
支持部１４ｂの第２方向Ｄ２の一端（支持部１４ｂの基端）は、基部１４ａの第１方向Ｄ１の一端（基部１４ａの先端）に接続されている。つまり、固定部１４は、概ねＬ字状に構成されている。基部１４ａの第１方向Ｄ１の他端（基部１４ａの基端）に位置する端面１４ｃは、刃部６ｂの側面に対応した形状を有しており、刃部６ｂに接触する接触面となる。 One end of the support portion 14b in the second direction D2 (base end of the support portion 14b) is connected to one end of the base portion 14a in the first direction D1 (tip of the base portion 14a). That is, the fixed portion 14 is substantially L-shaped. The end surface 14c located at the other end (base end of the base portion 14a) of the base portion 14a in the first direction D1 has a shape corresponding to the side surface of the blade portion 6b, and serves as a contact surface that contacts the blade portion 6b.
この端面１４ｃには、磁石（不図示）が設けられている。また、刃部６ｂは、強磁性体で形成されている。そのため、端面１４ｃを刃部６ｂに接触させると、固定部１４は、この磁石の磁力で刃部６ｂに固定される。なお、固定部１４が刃部６ｂに固定されると、支持部１４ｂの基部１４ａ側の表面１４ｄが刃部６ｂに対面する。 A magnet (not shown) is provided on the end face 14c. The blade portion 6b is made of a ferromagnetic material. Therefore, when the end face 14c is brought into contact with the blade portion 6b, the fixing portion 14 is fixed to the blade portion 6b by the magnetic force of this magnet. When the fixing portion 14 is fixed to the blade portion 6b, the surface 14d of the support portion 14b on the base portion 14a side faces the blade portion 6b.
表面１４ｄの第２方向Ｄ２の他端（支持部１４ｂの先端）側の位置には、第１方向Ｄ１に対して概ね平行な回転軸１６が設けられている。この回転軸１６は、第１方向Ｄ１から見て十字状に形成された突き当て部１８を回転できる態様で支持している。つまり、固定部１４と、この固定部１４の表面１４ｄ側に配置される突き当て部１８とは、回転軸１６を介して連結されている。 A rotation shaft 16 substantially parallel to the first direction D1 is provided at a position on the surface 14d on the other end (tip of the support portion 14b) side of the second direction D2. The rotating shaft 16 supports the abutting portion 18 formed in a cross shape when viewed from the first direction D1 in a rotatable manner. That is, the fixing portion 14 and the abutting portion 18 arranged on the surface 14d side of the fixing portion 14 are connected via the rotation shaft 16.
突き当て部１８は、回転軸１６が挿入される中央の軸受け部２０と、軸受け部２０を囲むように環状に配置された４つの位置規定部２２，２４，２６，２８と、を含む。４つの位置規定部２２，２４，２６，２８は、それぞれ、第１方向Ｄ１の長さ（厚み）が異なる直方体状の本体部２２ａ，２４ａ，２６ａ，２８ａを有している。本実施形態では、本体部２２ａ，２４ａ，２６ａ，２８ａの第１方向Ｄ１の長さが、この順序で大きくなっている。 The abutting portion 18 includes a central bearing portion 20 into which the rotating shaft 16 is inserted, and four positioning portions 22, 24, 26, 28 arranged in an annular shape so as to surround the bearing portion 20. The four positioning portions 22, 24, 26, and 28 each have rectangular parallelepiped main body portions 22a, 24a, 26a, and 28a having different lengths (thicknesses) in the first direction D1. In the present embodiment, the lengths of the main bodies 22a, 24a, 26a, 28a in the first direction D1 increase in this order.
本体部２２ａ，２４ａ，２６ａ，２８ａの支持部１４ｂとは反対側の表面には、任意の厚みの補助プレート２２ｂ，２４ｂ，２６ｂ，２８ｂが装着されている。補助プレート２２ｂ，２４ｂ，２６ｂ，２８ｂは、それぞれ、表面と、表面とは反対側の裏面と、を有しており、本体部２２ａ，２４ａ，２６ａ，２８ａ（突き当て部１８）に対して着脱できるように構成されている。 Auxiliary plates 22b, 24b, 26b, 28b of arbitrary thickness are mounted on the surface of the main body portions 22a, 24a, 26a, 28a opposite to the support portion 14b. The auxiliary plates 22b, 24b, 26b, 28b each have a front surface and a back surface opposite to the front surface, and are attached to and detached from the main body portions 22a, 24a, 26a, 28a (butting portion 18). It is configured so that it can be done.
具体的には、この補助プレート２２ｂ，２４ｂ，２６ｂ，２８ｂの裏面側が、本体部２２ａ，２４ａ，２６ａ，２８ａの表面側に装着される。補助プレート２２ｂ，２４ｂ，２６ｂ，２８ｂの表面は、位置規定部２２，２４，２６，２８の表面２２ｃ，２４ｃ，２６ｃ，２８ｃとなる。つまり、この表面２２ｃ，２４ｃ，２６ｃ，２８ｃも、軸受け部２０（回転軸１６）を囲む環状に配列されている。 Specifically, the back surface side of the auxiliary plates 22b, 24b, 26b, 28b is attached to the front surface side of the main body portions 22a, 24a, 26a, 28a. The surfaces of the auxiliary plates 22b, 24b, 26b, 28b are the surfaces 22c, 24c, 26c, 28c of the positioning portions 22, 24, 26, 28. That is, the surfaces 22c, 24c, 26c, 28c are also arranged in an annular shape surrounding the bearing portion 20 (rotating shaft 16).
位置規定部２２，２４，２６，２８の表面２２ｃ，２４ｃ，２６ｃ，２８ｃと固定部１４の端面１４ｃとの第１方向Ｄ１の距離は、互いに異なっている。そのため、端面１４ｃを刃部６ｂに接触させて固定部１４を刃部６ｂに固定した上で、任意のいずれかの表面２２ｃ，２４ｃ，２６ｃ，２８ｃにワイヤ１の端部を突き当てれば、選択された表面２２ｃ，２４ｃ，２６ｃ，２８ｃに応じてワイヤ１の端部と刃部６ｂとの距離が決まる。 The distances in the first direction D1 between the surfaces 22c, 24c, 26c, 28c of the positioning portions 22, 24, 26, 28 and the end surface 14c of the fixing portion 14 are different from each other. Therefore, if the end surface 14c is brought into contact with the blade portion 6b to fix the fixing portion 14 to the blade portion 6b, and then the end portion of the wire 1 is abutted against any of the surfaces 22c, 24c, 26c, 28c, the selection is made. The distance between the end portion of the wire 1 and the blade portion 6b is determined according to the surface 22c, 24c, 26c, 28c formed.
つまり、任意のいずれかの表面２２ｃ，２４ｃ，２６ｃ，２８ｃにワイヤ１の端部を突き当てることで、ワイヤ１の絶縁被覆層１ｂが刃部６ｂ，８ｂによって切断される切断位置も決まる。よって、表面２２ｃ，２４ｃ，２６ｃ，２８ｃにワイヤ１の端部を突き当てることで、ワイヤ１の絶縁被覆層１ｂを所望の位置で切断できるようになる。 That is, by abutting the end portion of the wire 1 against any one of the surfaces 22c, 24c, 26c, 28c, the cutting position where the insulating coating layer 1b of the wire 1 is cut by the blade portions 6b, 8b is also determined. Therefore, by abutting the end portion of the wire 1 against the surfaces 22c, 24c, 26c, 28c, the insulating coating layer 1b of the wire 1 can be cut at a desired position.
このように、刃部６ｂに対面する表面２２ｃ，２４ｃ，２６ｃ，２８ｃは、それぞれ、ワイヤ１の端部が突き当てられる突き当て面として機能する。また、突き当て部１８は、この突き当て面にワイヤ１の端部が突き当てられることで、ワイヤ１の絶縁被覆層１ｂが刃部６ｂ，８ｂによって切断される切断位置を規定する。 In this way, the surfaces 22c, 24c, 26c, and 28c facing the blade portion 6b each function as an abutting surface to which the end portion of the wire 1 is abutted. Further, the abutting portion 18 defines a cutting position where the insulating coating layer 1b of the wire 1 is cut by the blade portions 6b and 8b when the end portion of the wire 1 is abutted against the abutting surface.
なお、ワイヤ１の切断位置は、本体部２２ａ，２４ａ，２６ａ，２８ａの厚み（第１方向Ｄ１の長さ）と、各補助プレート２２ｂ，２４ｂ，２６ｂ，２８ｂの厚み（表面と裏面との距離）と、に依存している。よって、所望の厚みの補助プレート２２ｂ，２４ｂ，２６ｂ，２８ｂを、対応する本体部２２ａ，２４ａ，２６ａ，２８ａに装着することで、本体部２２ａ，２４ａ，２６ａ，２８ａの厚みと補助プレート２２ｂ，２４ｂ，２６ｂ，２８ｂの厚みとに応じたワイヤ１の切断位置を設定できる。 The cutting positions of the wire 1 are the thicknesses of the main bodies 22a, 24a, 26a, 28a (the length of the first direction D1) and the thicknesses of the auxiliary plates 22b, 24b, 26b, 28b (distance between the front surface and the back surface). ) And depends on. Therefore, by mounting the auxiliary plates 22b, 24b, 26b, 28b having a desired thickness on the corresponding main body portions 22a, 24a, 26a, 28a, the thickness of the main body portions 22a, 24a, 26a, 28a and the auxiliary plate 22b, The cutting position of the wire 1 can be set according to the thicknesses of 24b, 26b, and 28b.
また、突き当て部１８は、表面２２ｃ，２４ｃ，２６ｃ，２８ｃ（複数の突き当て面）が配列する方向に沿って回転できるように、回転軸１６によって支持されている。そのため、例えば、突き当て部１８を回転させることで、刃部６ｂ，８ｂの任意の刃６ｃ，８ｃに対面する表面２２ｃ，２４ｃ，２６ｃ，２８ｃを選択できる。つまり、使用される表面２２ｃ，２４ｃ，２６ｃ，２８ｃを選択して、ワイヤ１の切断位置を容易に変更できる。 Further, the abutting portion 18 is supported by a rotation shaft 16 so that the abutting portion 18 can rotate along the direction in which the surfaces 22c, 24c, 26c, 28c (a plurality of abutting surfaces) are arranged. Therefore, for example, by rotating the abutting portion 18, the surfaces 22c, 24c, 26c, 28c of the blade portions 6b, 8b facing the arbitrary blades 6c, 8c can be selected. That is, the surfaces 22c, 24c, 26c, 28c to be used can be selected, and the cutting position of the wire 1 can be easily changed.
図３は、切断ユニット２ａに切断位置規定ユニット２ｂが装着される様子を示す側面図である。切断ユニット２ａに切断位置規定ユニット２ｂを装着する際には、図３に示すように、切断位置規定ユニット２ｂの端面１４ｃを切断ユニット２ａの刃部６ｂに接触させれば良い。 FIG. 3 is a side view showing how the cutting position defining unit 2b is mounted on the cutting unit 2a. When the cutting position defining unit 2b is mounted on the cutting unit 2a, as shown in FIG. 3, the end surface 14c of the cutting position defining unit 2b may be brought into contact with the blade portion 6b of the cutting unit 2a.
これにより、端面１４ｃに設けられている磁石の磁力で切断位置規定ユニット２ｂが切断ユニット２ａに固定される。なお、本実施形態では、端面１４ｃを刃部６ｂに接触させることで、切断位置規定ユニット２ｂを切断ユニット２ａに装着しているが、端面１４ｃを刃部８ｂに接触させることで、切断位置規定ユニット２ｂを切断ユニット２ａに装着することもできる。 As a result, the cutting position defining unit 2b is fixed to the cutting unit 2a by the magnetic force of the magnet provided on the end surface 14c. In the present embodiment, the cutting position defining unit 2b is attached to the cutting unit 2a by contacting the end face 14c with the blade portion 6b, but the cutting position defining unit 2b is attached by contacting the end surface 14c with the blade portion 8b. The unit 2b can also be attached to the cutting unit 2a.
続いて、上述したワイヤストリッパ２の使用方法を説明する。図４は、ワイヤストリッパ２によって絶縁被覆層１ｂが切断される様子を示す側面図である。まず、ワイヤ１の導体１ａの径に対応する径の刃６ｃ，８ｃを絶縁被覆層１ｂに接触させるようにワイヤ１を刃部６ｂと刃部８ｂとで軽く挟んで、ワイヤストリッパ２でワイヤ１を保持する。なお、このワイヤ１は、例えば、銅等の金属でなる線状の導体１ａの周囲を樹脂等でなる絶縁被覆層１ｂで被覆することにより形成されている。 Subsequently, a method of using the wire stripper 2 described above will be described. FIG. 4 is a side view showing how the insulating coating layer 1b is cut by the wire stripper 2. First, the wire 1 is lightly sandwiched between the blade portion 6b and the blade portion 8b so that the blades 6c and 8c having a diameter corresponding to the diameter of the conductor 1a of the wire 1 are brought into contact with the insulating coating layer 1b, and the wire 1 is used by the wire stripper 2. To hold. The wire 1 is formed by, for example, covering the periphery of a linear conductor 1a made of a metal such as copper with an insulating coating layer 1b made of a resin or the like.
次に、突き当て部１８を回転させて、ワイヤ１から除去したい絶縁被覆層１ｂの長さに対応した突き当て面を上述の刃６ｃ，８ｃに対面させる。つまり、表面２２ｃ，２４ｃ，２６ｃ，２８ｃのいずれかを選択する。図４の例では、表面２４ｃが選択されている。そして、この選択された表面２４ｃにワイヤ１の端部を突き当てるように、刃部６ｂ，８ｂに対するワイヤ１の位置を調整する。 Next, the abutting portion 18 is rotated so that the abutting surface corresponding to the length of the insulating coating layer 1b to be removed from the wire 1 faces the above-mentioned blades 6c and 8c. That is, any one of the surfaces 22c, 24c, 26c, and 28c is selected. In the example of FIG. 4, the surface 24c is selected. Then, the position of the wire 1 with respect to the blade portions 6b and 8b is adjusted so that the end portion of the wire 1 abuts against the selected surface 24c.
その後、把持部６ａと把持部８ａとを強く把持して、一対の刃部６ｂ，８ｂを閉じる。これにより、絶縁被覆層１ｂに刃６ｃ，８ｃを押し当てて、所望の長さの絶縁被覆層１ｂを切断できる。すなわち、所望の切断位置１ｃで絶縁被覆層１ｂが切断される。絶縁被覆層１ｂを切断した後には、この切断された絶縁被覆層１ｂをワイヤ１から除去する。これにより、線状の導体１ａを部分的に露出させることができる。 After that, the grip portion 6a and the grip portion 8a are strongly gripped to close the pair of blade portions 6b and 8b. As a result, the blades 6c and 8c can be pressed against the insulating coating layer 1b to cut the insulating coating layer 1b having a desired length. That is, the insulating coating layer 1b is cut at the desired cutting position 1c. After cutting the insulating coating layer 1b, the cut insulating coating layer 1b is removed from the wire 1. As a result, the linear conductor 1a can be partially exposed.
以上のように、本実施形態のワイヤストリッパ２は、磁力で刃部６ｂに固定される固定部１４と、ワイヤ１の端部が突き当てられる表面２２ｃ，２４ｃ，２６ｃ，２８ｃ（突き当て面）を含む突き当て部１８と、を有する切断位置規定ユニット２ｂを備えている。 As described above, the wire stripper 2 of the present embodiment has a fixing portion 14 fixed to the blade portion 6b by a magnetic force and surfaces 22c, 24c, 26c, 28c (butting surfaces) to which the end portion of the wire 1 is abutted. It is provided with a cutting position defining unit 2b having an abutting portion 18 including.
よって、いずれかの表面２２ｃ，２４ｃ，２６ｃ，２８ｃにワイヤ１の端部を突き当てれば、この切断位置規定ユニット２ｂによって規定される切断位置１ｃで絶縁被覆層１ｂを切断できる。つまり、作業者の直感に基づいて切断位置１ｃを決める必要がなく、また、切断位置１ｃに目印等を付す必要もない。よって、絶縁被覆層１ｂを簡単かつ適切に切断できる。 Therefore, if the end of the wire 1 is abutted against any of the surfaces 22c, 24c, 26c, 28c, the insulating coating layer 1b can be cut at the cutting position 1c defined by the cutting position defining unit 2b. That is, it is not necessary to determine the cutting position 1c based on the intuition of the operator, and it is not necessary to put a mark or the like on the cutting position 1c. Therefore, the insulating coating layer 1b can be easily and appropriately cut.
なお、本発明は、上述した実施形態の記載に制限されず種々変更して実施可能である。例えば、上述の実施形態では、刃部６ｂ，８ｂを強磁性体で形成し、端面１４ｃに磁石を設けているが、例えば、刃部６ｂ，８ｂに磁石を設け、端面１４ｃを強磁性体で形成しても良い。また、刃部６ｂ，８ｂと端面１４ｃとの両方に磁石を設けることもできる。 The present invention is not limited to the description of the above-described embodiment, and can be implemented with various modifications. For example, in the above-described embodiment, the blade portions 6b and 8b are formed of a ferromagnet and a magnet is provided on the end face 14c. For example, a magnet is provided on the blade portions 6b and 8b and the end face 14c is made of a ferromagnet. It may be formed. Further, magnets can be provided on both the blade portions 6b and 8b and the end face 14c.
その他、上述した実施形態にかかる構造、方法等は、本発明の目的の範囲を逸脱しない限りにおいて適宜変更して実施できる。 In addition, the structure, method, and the like according to the above-described embodiment can be appropriately modified and implemented as long as they do not deviate from the scope of the object of the present invention.
