Description

本発明はシールド電線の箔剥ぎ冶具、特にシールド電線を構成する線芯に巻かれた箔を剥ぎ取るシールド電線の箔剥ぎ冶具に関する。   The present invention relates to a foil stripping jig for a shielded electric wire, and more particularly to a foil stripping jig for a shielded electric wire that strips off the foil wound around a wire core that constitutes the shielded electric wire.

従来、シールド電線は、線芯の外周に金属箔が巻かれ、金属箔の外周が絶縁性のシースによって被覆されている。そして、シールド電線同士を接続する際、端部の所定範囲ではシースおよび金属箔を撤去して線芯を剥き出しにしている。
このため、端部の所定範囲のシースを撤去した後、金属箔に切り込みを入れて金属箔を切断除去する発明（切断刃ユニット）が開示されている（たとえば、特許文献１参照）。 Conventionally, in a shielded electric wire, a metal foil is wound around the outer circumference of a wire core, and the outer circumference of the metal foil is covered with an insulating sheath. Then, when the shielded wires are connected to each other, the sheath and the metal foil are removed to expose the wire core in a predetermined range of the end portion.
Therefore, there is disclosed an invention (cutting blade unit) in which a sheath in a predetermined range at the end is removed, and then a cut is made in the metal foil to cut and remove the metal foil (for example, refer to Patent Document 1).

特許第５２４７４０４号公報（第３−５頁、図２）Japanese Patent No. 5247404 (page 3-5, FIG. 2)

特許文献１に開示された発明は、シースが撤去されているシールド電線の端面、すなわち金属箔が巻き付けられた線芯の端面を円錐状のテーパ面に押し付け、シース外面をチャック部材で把持し、テーパ面とチャック部材とを近づけた後、金属箔が巻き付けられた線芯を切断刃によって挟むものである。すなわち、前記近づけによって金属箔が巻き付けられた線芯を僅かに膨らませて、金属箔を容易に撓み変形しない状態にし、かかる安定した状態で切断刃を金属箔のみに切り込ませるものである。
しかしながら、前記膨らませた形状が必ずしも一定の形状に安定しない場合があるため、切り込み不足による剥ぎ取り残しや、切り込み過剰による線芯の損傷等のおそれがあるという問題があった。また、テーパ面とチャック材（あるいは切断刃）との距離が制限されるため、金属箔を剥ぎ取る範囲が制限されるという問題があった。さらに、テーパ面とチャック部材とを近づける機構や切断刃を移動させる機構を必要とするため、構造が複雑になり、操作が煩雑になると共に、装置コストが上昇するという問題があった。 The invention disclosed in Patent Document 1 presses the end surface of the shielded electric wire from which the sheath is removed, that is, the end surface of the wire core around which the metal foil is wound, against the tapered surface of the cone, and grips the outer surface of the sheath with a chuck member. After the taper surface and the chuck member are brought close to each other, the wire core around which the metal foil is wound is sandwiched by the cutting blades. That is, the wire core around which the metal foil is wound is slightly inflated by the above-mentioned approach so that the metal foil is not easily bent and deformed, and the cutting blade is cut only into the metal foil in such a stable state.
However, since the inflated shape may not always be stable to a constant shape, there is a problem that there is a risk of unstriped due to insufficient cutting, damage to the wire core due to excessive cutting, and the like. Further, since the distance between the tapered surface and the chuck material (or the cutting blade) is limited, there is a problem that the range for stripping the metal foil is limited. Furthermore, since a mechanism for bringing the tapered surface and the chuck member closer to each other and a mechanism for moving the cutting blade are required, the structure becomes complicated, the operation becomes complicated, and the apparatus cost increases.

本発明は、前記問題を解消するものであり、線芯を損傷することなく容易に箔のみを確実に剥ぎ取ることが可能で、箔を剥ぎ取る範囲の制約がない簡素な構造のシールド電線の箔剥ぎ冶具を提供することにある。   The present invention is to solve the above problems, it is possible to easily reliably peel off only the foil without damaging the wire core, the shielded wire of a simple structure without restriction of the stripping range of the foil To provide a foil stripping jig.

本発明に係るシールド電線の箔剥ぎ冶具は、線芯と前記線芯に巻き付けられた箔と前記箔を被覆するシースとを具備するシールド電線において、前記シースが撤去された範囲における前記箔を前記線芯から剥ぎ取るシールド電線の箔剥ぎ冶具であって、前記シールド電線が挿入される挿入孔を具備する挿入部と、前記挿入部に連通し、前記シールド電線の前記シースが撤去された範囲が挿入される剥離孔を具備する剥離部とを有し、前記剥離部には、前記剥離孔に空気を吹き出すための給気孔と前記給気孔から吹き出された空気を前記剥離孔から排出するための排気孔とが設けられ、前記吹き出された空気によって解きほぐされた前記箔の一部が、前記挿入孔の前記剥離孔側の端部または前記剥離孔の前記挿入孔側の端部に当接することを特徴とする。
また、線芯と前記線芯に巻き付けられた箔と前記箔を被覆するシースとを具備するシールド電線において、前記シースが撤去された範囲における前記箔を前記線芯から剥ぎ取るシールド電線の箔剥ぎ冶具であって、前記シールド電線が挿入される挿入孔を具備する挿入部と、前記挿入部に連通し、前記シールド電線の前記シースが撤去された範囲が挿入される剥離孔を具備する剥離部とを有し、前記剥離部には、前記剥離孔における前記挿入部と反対の側の端部から供給された空気を排出するための排気孔とが設けられ、前記供給された空気によって解きほぐされた前記箔の一部が、前記挿入孔の前記剥離孔側の端部または前記剥離孔の前記挿入孔側の端部に当接することを特徴とする。
さらに、前記挿入部と前記剥離部との間に、切断刃を具備する切断部が配置され、前記箔の一部は、前記挿入孔の前記剥離孔側の端部または前記剥離孔の前記挿入孔側の端部に代えて、あるいは前記挿入孔の前記剥離孔側の端部または前記剥離孔の前記挿入孔側の端部と共に、前記切断刃に当接することを特徴とする。

(Shielding foil stripping jig)
1 and 2 schematically illustrate a foil stripping jig for a shielded electric wire according to Embodiment 1 of the present invention. FIG. 1 is a cross-sectional view in side view showing the start of work, and FIG. It is a partial sectional view of a side view showing the middle.
In FIG. 1, a foil stripping jig 100 for shielded electric wire (hereinafter abbreviated as “foil stripping jig”) 100 is one in which a cylindrical insertion portion 10 and a cylindrical stripping portion 20 are integrally assembled.

挿入部１０には剥離部２０に向かって内径が縮小する円錐状（テーパ状）の挿入孔１１が形成されている。
また、剥離部２０には挿入孔１１の中心軸１９に一致する中心軸２９を具備する剥離孔２１が形成されている。そして、剥離孔２１に平行な給気孔２２と、給気孔２２と剥離孔２１とを連通する枝給気孔２３と、枝給気孔２３に対向した位置に配置された排気孔２４とが形成されている。
そして、給気孔２２の一方の端面（以下「給気孔閉塞端部」と称す）２２ａは挿入部１０によって閉塞され、他方の端面（以下「給気孔開口端部」と称す）２２ｂは開口している。 The insertion portion 10 has a conical (tapered) insertion hole 11 whose inner diameter decreases toward the peeling portion 20.
Further, the peeling portion 20 is formed with a peeling hole 21 having a central axis 29 coinciding with the central axis 19 of the insertion hole 11. Then, an air supply hole 22 parallel to the separation hole 21, a branch air supply hole 23 that connects the air supply hole 22 and the separation hole 21 to each other, and an exhaust hole 24 arranged at a position facing the branch air supply hole 23 are formed. There is.
Then, one end surface (hereinafter referred to as “air supply hole closed end”) 22a of the air supply hole 22 is closed by the insertion portion 10, and the other end surface (hereinafter referred to as “air supply hole open end”) 22b is opened. There is.

したがって、給気孔開口端部２２ｂ側から供給された空気は、給気孔２２を経由して枝給気孔２３から剥離孔２１内に吹き出され、排気孔２４から排出される（正確には、剥離孔２１の開口している他方の面（以下「剥離孔開口端部」と称す）２１ｂからも排出される）。
なお、挿入孔１１の剥離孔２１側の端部（以下「挿入孔端部」と称す）１１ｂにおける内径（以下「挿入孔内径」称す）は、剥離孔２１の挿入孔１１側の端部（以下「剥離孔端部」と称す）２１ａにおける内径（以下「剥離孔内径」と称す）よりも小さくなっている。このため、シールド電線４のシース３が撤去された範囲（線芯１の箔２が露出した範囲に同じ）は、剥離孔２１に滑らかに挿入される。 Therefore, the air supplied from the air supply hole opening end 22b side is blown out from the branch air supply hole 23 into the separation hole 21 via the air supply hole 22 and is discharged from the exhaust hole 24 (to be exact, the separation hole). It is also discharged from the other open surface of 21 (hereinafter referred to as “peeling hole opening end”) 21b).
The inner diameter (hereinafter referred to as "insertion hole inner diameter") of the end portion of the insertion hole 11 on the peeling hole 21 side (hereinafter referred to as "insertion hole end portion") 11b is the end portion of the peeling hole 21 on the insertion hole 11 side (hereinafter referred to as "insertion hole inner diameter"). Hereinafter, it is smaller than the inner diameter of the "peel hole end portion" 21a (hereinafter referred to as the "peel hole inner diameter"). Therefore, the range where the sheath 3 of the shielded electric wire 4 is removed (same as the range where the foil 2 of the wire core 1 is exposed) is smoothly inserted into the peeling hole 21.

（箔剥ぎ状況）
次に、箔剥ぎ冶具１００における箔剥ぎの状況を模式的に説明する。
図１において、シールド電線４は、中央に線芯１と、線芯１に巻き付けられた箔２と、箔２を被覆するシース３とを具備している。そして、シールド電線４は端部から所定の範囲において、シース３が撤去されて箔２が剥きだしになった状態で、挿入孔１１に挿入され、剥きだしになっている箔２の範囲が剥離孔２１に侵入している。なお、線芯１の外周（箔２の内周に同じ）に絶縁被覆が施される場合がある。 (Foil stripping situation)
Next, the situation of foil stripping in the foil stripping jig 100 will be schematically described.
In FIG. 1, the shielded electric wire 4 is provided with a wire core 1, a foil 2 wound around the wire core 1, and a sheath 3 covering the foil 2 in the center. Then, the shielded electric wire 4 is inserted into the insertion hole 11 in a state where the sheath 3 is removed and the foil 2 is exposed in a predetermined range from the end portion, and the exposed area of the foil 2 is peeled off. It has entered the hole 21. The outer circumference of the wire core 1 (the same as the inner circumference of the foil 2) may be coated with an insulating coating.

図２において、給気孔２２に供給された空気は枝給気孔２３から吹き出しているから、巻き付けられていた箔２は線芯１から解きほぐされ、解きほぐされた箔２は風圧によって剥離孔２１の内面に押し付けられたり、排気孔２４に向けて手繰り寄せられたりしている（なお、解きほぐされた箔２の形態は様々であるから、図示された形態はイメージであって、必ずしも正確ではない）。
このとき、挿入孔１１の内径は剥離孔２１の内径よりも小さく、挿入孔端部１１ｂは中心軸１９に向かって突出し、剥離孔端部２１ａとの間に段差を形成しているから、箔２の一部は挿入孔端部１１ｂに押し付けられる。そうすると、解きほぐされた箔２は、挿入孔端部１１ｂによって曲げられたり切り込まれたりして切断される場合がある。 In FIG. 2, since the air supplied to the air supply holes 22 is blown out from the branch air supply holes 23, the wound foil 2 is unraveled from the wire core 1, and the unraveled foil 2 is separated by the wind pressure from the peeling holes 21. It is pressed against the inner surface of the sheet or is drawn toward the exhaust hole 24 (note that since the unfolded foil 2 has various shapes, the illustrated shape is an image and is not necessarily accurate. Absent).
At this time, the inner diameter of the insertion hole 11 is smaller than the inner diameter of the peeling hole 21, the insertion hole end portion 11b projects toward the central axis 19, and a step is formed between the insertion hole end portion 11b and the peeling hole end portion 21a. A part of 2 is pressed against the insertion hole end 11b. Then, the unfolded foil 2 may be cut by being bent or cut by the insertion hole end 11b.

さらに、シールド電線４と箔剥ぎ冶具１００とを中心軸１９（中心軸２９に同じ）を中心として相対的に回転すると、箔２の一部は、挿入孔端部１１ｂに押し付けられた状態で挿入孔端部１１ｂに摺動するから、箔２は容易かつ確実に切断され、線芯１から離脱することになる。
そして、剥離孔２１内に剥離孔端部２１ａの方向に空気を吹き込むことによって、あるいは剥離孔端部２１ａから空気を吸い込むことによって、切断された箔２は剥離孔２１の外に確実にエアーブローされる。 Further, when the shielded wire 4 and the foil stripping jig 100 are relatively rotated about the central axis 19 (same as the central axis 29), a part of the foil 2 is inserted while being pressed against the insertion hole end 11b. Since the foil 2 slides on the hole end portion 11b, the foil 2 is easily and surely cut and separated from the wire core 1.
Then, by blowing air into the peeling hole 21 toward the peeling hole end 21a or sucking air from the peeling hole end 21a, the cut foil 2 is surely blown out of the peeling hole 21. To be done.

なお、以上は、挿入孔内径が剥離孔内径よりも小さい場合であるが、本発明はこれに限定するものではない。挿入孔内径が剥離孔内径よりも大きい場合であっても、解きほぐされた箔２は風圧によって剥離孔２１の内面に押し付けられ、剥離孔端部２１ａによって曲げられたり切り込まれたりして切断する場合がある。そして、前記相対的な回転によって、箔２の一部は剥離孔端部２１ａに摺動するから、箔２は容易かつ確実に切断されることになる。
また、以上は、一方の手でシールド電線４を掴みながら他方の手で箔剥ぎ冶具１００を掴んで作業しているが、箔剥ぎ冶具１００を固定して、一方の手のみで作業してもよい。
さらに、挿入部１０と剥離部２０との間に、中央孔の内周に切断刃が形成された切断部を配置して、かかる切断刃によって箔２を切断するようにしてもよい（実施の形態２参照）。 The above is the case where the inner diameter of the insertion hole is smaller than the inner diameter of the peeling hole, but the present invention is not limited to this. Even when the inner diameter of the insertion hole is larger than the inner diameter of the peeling hole, the unfolded foil 2 is pressed against the inner surface of the peeling hole 21 by the wind pressure, and is bent or cut by the peeling hole end 21a to cut. There is a case. Then, due to the relative rotation, a part of the foil 2 slides on the peeling hole end 21a, so that the foil 2 is easily and surely cut.
Further, in the above, the work is performed by grasping the shielded wire 4 with one hand and the foil stripping jig 100 with the other hand, but the foil stripping jig 100 is fixed and the work is performed with only one hand. Good.
Further, a cutting portion having a cutting blade formed on the inner circumference of the central hole may be arranged between the insertion portion 10 and the peeling portion 20, and the foil 2 may be cut by the cutting blade (implementation). (See Form 2).

（作用効果）
箔剥ぎ冶具１００は以上の構成であって、吹き出された空気によって線芯１に巻き付けられていた箔２が解きほぐされて剥離孔２１の内面に押し付けられると共に、箔２の一部が挿入孔端部１１ｂまたは剥離孔端部２１ａに当接して切断されるから、線芯１を損傷することなく容易かつ確実に箔２のみを剥ぎ取ることが可能になる。
また、剥離孔２１の長さは制限されないから、箔２を剥ぎ取る範囲が制限されることがない。さらに、構造が簡素で軽量であるから、扱いが容易で治具の製造コストが安価になる。 (Effect)
The foil stripping jig 100 has the above-mentioned configuration, and the foil 2 wound around the wire core 1 is unraveled by the blown air and pressed against the inner surface of the peeling hole 21, and a part of the foil 2 is inserted into the insertion hole. Since the end portion 11b or the peeling hole end portion 21a is abutted and cut, only the foil 2 can be peeled off easily and reliably without damaging the wire core 1.
Further, since the length of the peeling hole 21 is not limited, the peeling range of the foil 2 is not limited. Further, since the structure is simple and lightweight, the handling is easy and the jig manufacturing cost is low.

Therefore, the wound foil 2 is unraveled from the wire core 1 by the momentum of the supplied air, and the unraveled foil 2 is spread by the wind pressure and pressed against the cutting blade 31 (note that the foil 2 is unraveled). Since the shapes of the foil 2 are various, the illustrated shape is an image and is not always accurate, and the unfolded foil 2 is not pressed only to the cutting blade 31 but is inserted into the end of the insertion hole. 11b and the peeling hole end 21a may be pressed).

このとき、箔２の一部は切断刃３１によって曲げられたり切り込まれたりして切断される。さらに、シールド電線４と箔剥ぎ冶具１００とを中心軸１９を中心として相対的に回転すると、箔２の一部は切断刃３１に押し付けられた状態で摺動するから、箔２は容易かつ確実に切断され、線芯１から離脱することになる。
そして、剥離孔２１内に剥離孔端部２１ａの方向に空気を吹き込むことによって、切断された箔２は剥離孔２１の外に確実にエアーブローされる。


At this time, a part of the foil 2 is bent or cut by the cutting blade 31 and cut. Further, when the shielded electric wire 4 and the foil stripping jig 100 are relatively rotated about the central axis 19, part of the foil 2 slides while being pressed against the cutting blade 31, so that the foil 2 is easy and reliable. Then, the wire core 1 is separated from the wire core 1.
Then, by blowing air into the peeling hole 21 in the direction of the peeling hole end portion 21 a , the cut foil 2 is reliably blown out of the peeling hole 21.


なお、以上は、切断部３０が設置された場合であるが、本発明はこれに限定するものではなく、実施の形態１と同様に切断部３０を撤去してもよい。このとき、解きほぐされた箔２は風圧によって挿入孔端部１１ｂあるいは剥離孔端部２１ａに押し付けられて切断され、さらに、シールド電線４と箔剥ぎ冶具２００とを中心軸１９を中心として相対的に回転すると、箔２はさらに容易かつ確実に切断され、線芯１から離脱することになる。
なお、図３には「線芯１に巻き付けられた箔２」として、スパイラル状に巻き付けた「スパイラルタイプ」を示しているが、本発明は箔２の設置形態をこれに限定するものではなく、たとえば、中心軸１９と平行（縦）に沿わして、側縁２ａおよび側縁２ｂに近い所定範囲を重ねた「縦沿えタイプ」であってもよい（図５参照、実施の形態１においても同じ）。なお、図５において、所定範囲を離して示しているが、かかる所定範囲は密着するものである。 The above is the case where the cutting unit 30 is installed, but the present invention is not limited to this, and the cutting unit 30 may be removed as in the first embodiment. At this time, the unfolded foil 2 is pressed against the insertion hole end portion 11b or the peeling hole end portion 21a by the wind pressure to be cut, and further, the shielded wire 4 and the foil peeling jig 200 are relatively centered around the central axis 19. When the foil 2 is rotated to, the foil 2 is more easily and surely cut and separated from the wire core 1.
3 shows a "spiral type" in which the foil 2 is wrapped around the wire core 1 in a spiral shape, the present invention is not limited to this. For example, it may be a “longitudinal type” in which a predetermined range close to the side edge 2a and the side edge 2b is overlapped along the parallel (longitudinal) with the central axis 19 (see FIG. 5, in the first embodiment). The same). In FIG. 5, the predetermined range is shown separated, but the predetermined range is in close contact.

（作用効果）
箔剥ぎ冶具２００は以上の構成であるから、実施の形態１において説明した箔剥ぎ冶具１００と同様の作用効果を奏する。特に、切断刃３１によって箔２が切断されるから、切断面は円周方向で均一に形成され、美観に富んでいる。また、切断刃３１の交換のみで確実な切断を継続することができるから、挿入孔端部１１ｂや剥離孔端部２１ａの摩耗に関わらず長期に渡って使用することができる。 (Effect)
Since the foil stripping jig 200 is configured as described above, it has the same effects as the foil stripping jig 100 described in the first embodiment. In particular, since the foil 2 is cut by the cutting blade 31, the cut surface is evenly formed in the circumferential direction, which is aesthetically pleasing. Further, since reliable cutting can be continued only by exchanging the cutting blade 31, it can be used for a long time regardless of wear of the insertion hole end portion 11b and the peeling hole end portion 21a.

以上、本発明を実施の形態１、２をもとに説明した。この実施の形態１、２は例示であり、それらの各構成要素およびその組合せにいろいろな変形例が可能なこと、またそうした変形例も本発明の範囲にあることは当業者に理解されるところである。   The present invention has been described above based on the first and second embodiments. The first and second embodiments are merely examples, and it is understood by those skilled in the art that various modifications can be made to the respective constituent elements and combinations thereof, and such modifications are also within the scope of the present invention. is there.

本発明は以上であるから、各種形態のシールド電線における線芯に巻き付けられて箔を剥ぎ取るシールド電線の箔剥ぎ冶具として広く利用することができる。   INDUSTRIAL APPLICABILITY Since the present invention is as described above, it can be widely used as a foil peeling jig for a shielded electric wire that is wound around a wire core in various forms of the shielded electric wire to peel off the foil.
