しかしながら、電線圧着部が同一形状で、端子突起部の突出方向が相違する電線圧着端子が新規に必要になった場合には、端子突起部の延出方向ごとに圧着条件の設定や圧着性能の評価が要求されるため、多大な評価工数および費用が発生するとともに、電線圧着端子の種類が増加するという問題があった。   However, if a new wire crimping terminal with the same shape of the wire crimping part and a different protruding direction of the terminal protrusion is required, the setting of the crimping conditions and the crimping performance should be different for each extension direction of the terminal protrusion. Since the evaluation is required, there are problems that a great amount of evaluation man-hours and costs occur and the types of wire crimp terminals increase.

また、特許文献1に開示されたブランク材は、相手側の部材に対してボルト締結されるものではなく、ワイヤハーネスの組み付け違いを防止するための目印となる端子突起部に相当する構成を有していない。   In addition, the blank material disclosed in Patent Document 1 is not bolted to the mating member, and has a configuration corresponding to a terminal protrusion serving as a mark for preventing a wrong assembly of the wire harness. Not done.

本発明は、上述した問題に鑑みてなされたもので、電線圧着部が同一形状で、端子突起部の突出方向が相違する電線圧着端子とする前のブランク材の段階で予め各種の評価試験をクリアしておけば、新規に電線圧着端子が必要になったときには、ブランク材に対して多大な評価工数および費用が発生せず、ブランク材の種類が増加することがない電線圧着端子用ブランク材、電線アッセンブリーおよびワイヤハーネスの製造方法を提供することを目的としている。   The present invention has been made in view of the above-described problems, and various evaluation tests are performed in advance at the stage of the blank material before the wire crimping terminal has the same shape and the protruding direction of the terminal protrusion is different. If clear, when new wire crimping terminals are required, there will be no significant evaluation man-hours and costs for the blanks, and the types of blanks will not increase. It aims at providing the manufacturing method of an electric wire assembly and a wire harness.

本発明に係る電線圧着端子用ブランク材は、上記課題を解決するため、金属板をプレスにより所定平面形状に打ち抜き加工されてなる電線圧着端子用ブランク材であって、一端側に形成され、電線の端末部が圧着される電線圧着部と、他端側に形成された板取り部と、を備え、前記板取り部は、中心部にボルト通し孔を有する端子接続部に対応する中心側領域と、前記中心側領域より周囲に延出している周辺側領域と、を有し、前記周辺側領域は、前記端子接続部から所定方向に一体に延出される端子突起部に対応する張出領域と、前記端子接続部および前記端子突起部との境界に沿って切除される切除領域と、を含んでいる構成である。   The wire crimp terminal blank according to the present invention is a wire crimp terminal blank formed by punching a metal plate into a predetermined planar shape by pressing in order to solve the above problems, and is formed on one end side. A wire crimping portion to which the terminal portion of the wire is crimped, and a plate-cut portion formed on the other end side, the plate-cut portion corresponding to a terminal connection portion having a bolt through hole in the center portion. And a peripheral side region extending to the periphery from the central side region, and the peripheral side region is an overhang region corresponding to a terminal protrusion that integrally extends in a predetermined direction from the terminal connection portion And an excision region that is excised along a boundary between the terminal connection part and the terminal projection part.

この構成によれば、本発明に係る電線圧着端子用ブランク材は、電線の端末部に電線圧着部が圧着されるまでは、板取り部の周辺側領域に含まれる切除領域が切除されず、電線の端末部に電線圧着部が圧着されてから、切除領域が切除され端子接続部および端子接続部から所定方向に延出される端子突起部が形成される。   According to this configuration, the wire crimping terminal blank according to the present invention is not excised from the excision region included in the peripheral region of the plate removing part until the electric wire crimping part is crimped to the terminal part of the electric wire. After the electric wire crimping portion is crimped to the terminal portion of the electric wire, the excision region is excised, and the terminal projection and the terminal projection that extends from the terminal connection portion in a predetermined direction are formed.

本発明に係る電線圧着端子用ブランク材は、端子突起部をどのような方向に延出させる場合でも、電線の端末部に電線圧着部が圧着されるまでの板取り部の周辺側領域の形状は変わらないため、電線圧着部が同一形状で、端子突起部の突出方向が相違する電線圧着端子とする前のブランク材の段階で予め各種の評価試験をクリアしておけば、新規に電線圧着端子が必要になったときには、ブランク材に対して多大な評価工数および費用が発生せず、ブランク材の種類が増加することがない。   The blank material for an electric wire crimping terminal according to the present invention has a shape of the peripheral side region of the plate take-up portion until the electric wire crimping portion is crimped to the terminal portion of the electric wire, regardless of the direction in which the terminal protrusion is extended. Since the wire crimping part has the same shape and the protruding direction of the terminal protrusion part is different, if you clear various evaluation tests in advance at the blank material stage before making the wire crimping terminal, new wire crimping When a terminal is required, a great evaluation man-hour and cost are not generated for the blank material, and the type of blank material does not increase.

本発明に係る電線アッセンブリーは、電線と、上記の電線圧着端子用ブランク材と、を備え、前記電線圧着部に前記電線の端末部が圧着されている構成である。   The electric wire assembly which concerns on this invention is a structure provided with the electric wire and said blank material for electric wire crimping terminals, and the terminal part of the said electric wire is crimped | bonded by the said electric wire crimping part.

この構成によれば、本発明に係る電線アッセンブリーは、周辺領域が端子接続部に対応する中心側領域の周辺に切除領域と、端子接続部および端子接続部から所定方向に対応する切除されない領域を含んでいる。   According to this configuration, in the wire assembly according to the present invention, the peripheral region includes a cut region around the center side region corresponding to the terminal connection portion, and a region that is not cut corresponding to a predetermined direction from the terminal connection portion and the terminal connection portion. Contains.

本発明に係る電線アッセンブリーは、端子突起部をどのような方向に延出させる場合でも、電線の端末部に電線圧着部を圧着させるまでの板取り部の周辺側領域の形状は変わらないため、電線圧着部が同一形状で、端子突起部の突出方向が相違する電線圧着端子とする前のブランク材の段階で予め各種の評価試験をクリアしておけば、新規に電線圧着端子が必要になったときには、ブランク材に対して多大な評価工数および費用が発生せず、ブランク材の種類が増加することがない。   Since the wire assembly according to the present invention does not change the shape of the peripheral side region of the plate take-up portion until the wire crimping portion is crimped to the terminal portion of the wire, in any direction in which the terminal protrusion extends. If you have cleared various evaluation tests in advance at the blank material stage before making the wire crimping terminal with the same shape and different protruding direction of the terminal protrusion, you will need a new wire crimping terminal In this case, a large evaluation man-hour and cost are not generated for the blank material, and the type of the blank material does not increase.

本発明に係る電線アッセンブリーは、電線圧着端子用ブランク材の電線圧着部に電線の端末部が圧着済みであるため、切除領域を切除されるだけでアッセンブリーを出荷することができ、電線圧着端子用ブランク材の在庫が過剰にならない。   The wire assembly according to the present invention has the terminal portion of the wire already crimped to the wire crimping portion of the wire crimping terminal blank, so that the assembly can be shipped simply by cutting the cut region, and for the wire crimping terminal. Blank stock does not become excessive.

本発明に係るワイヤハーネスの製造方法は、上記の電線圧着端子用ブランク材をプレスにより打ち抜き加工し、前記電線の端末部に前記電線圧着部を重ねて包んだ状態に圧着し、前記電線圧着端子用ブランク材の前記切除領域を切除することにより、前記端子接続部および前記端子突起部を形成させる構成である。   The method for manufacturing a wire harness according to the present invention includes punching the above-described blank material for a wire crimping terminal with a press, crimping the wire crimping portion in a state of wrapping the wire crimping portion on the terminal portion of the wire, and crimping the wire crimping terminal. It is the structure which forms the said terminal connection part and the said terminal projection part by excising the said excision area | region of the blank material.

この構成によれば、本発明に係るワイヤハーネスの製造方法は、電線の端末部に電線圧着端子用ブランク材の電線圧着部が圧着されてから、切除領域が切除され端子接続部および端子接続部から所定の方向に延出される端子突起部を形成される。   According to this configuration, in the method for manufacturing the wire harness according to the present invention, after the wire crimping portion of the wire crimping terminal blank material is crimped to the terminal portion of the wire, the excision region is excised, and the terminal connection portion and the terminal connection portion A terminal projection extending in a predetermined direction is formed.

本発明に係るワイヤハーネスの製造方法は、電線圧着端子用ブランク材の端子突起部をどのような方向に延出させる場合でも、電線の端末部に電線圧着部を圧着させるまでの板取り部の周辺側領域の形状は変わらないため、電線圧着部が同一形状で、端子突起部の突出方向が相違する電線圧着端子とする前のブランク材の段階で予め各種の評価試験をクリアしておけば、新規に電線圧着端子が必要になったときには、ブランク材に対して多大な評価工数および費用が発生せず、ブランク材の種類が増加することがない。   The method for manufacturing a wire harness according to the present invention is a method for producing a plate-clamping portion until a wire crimping portion is crimped to a terminal portion of an electric wire, regardless of the direction in which the terminal protrusion of the wire crimping terminal blank is extended. Since the shape of the peripheral area does not change, it is necessary to clear various evaluation tests in advance at the stage of the blank material before making the wire crimping terminal with the same shape and the different protruding direction of the terminal protrusion. When a wire crimping terminal is newly required, a great evaluation man-hour and cost are not generated for the blank material, and the type of the blank material does not increase.

本発明によれば、電線圧着部が同一形状で、端子突起部の突出方向が相違する電線圧着端子とする前のブランク材の段階で予め各種の評価試験をクリアしておけば、新規に電線圧着端子が必要になったときには、ブランク材に対して多大な評価工数および費用が発生せず、ブランク材の種類が増加することがない電線圧着端子用ブランク材、電線アッセンブリーおよびワイヤハーネスの製造方法を提供することができる。   According to the present invention, if various evaluation tests are cleared in advance at the stage of the blank material before making the wire crimping terminal having the same shape and the protruding direction of the terminal protrusion different from each other, the wire can be newly created. When a crimping terminal is required, the blank material for wire crimping terminal, the wire assembly, and the method of manufacturing the wire harness do not generate much evaluation man-hours and costs for the blank material and the type of the blank material does not increase. Can be provided.

The portion 12a is crimped in a state where it is wrapped and wrapped around the conductor 21a at the end of the end portion of the electric wire 21, and the second electric wire holding portion 12b is overlapped with the portion where the insulating coating material 21b of the end portion of the electric wire 21 is not peeled off. The cut region 13b-2 included in the peripheral side region 13b of the plate removing part 13 is not cut until it is crimped to the wrapped state.

本実施の形態に係る電線圧着端子用ブランク材11、電線アッセンブリーおよびワイヤハーネス1,1A,1Bは、電線21の端末部に電線圧着部12を圧着させてから、板取り部13の周辺側領域13bに含まれる切除領域13b−2を切除して端子接続部14および端子接続部14から所定方向に延出される端子突起部15,16,17を形成させる。なお、周辺側領域13bに含まれる切除領域13b−2を切除させる工程は、電線21の端末部に電線圧着部12を圧着させる工程と同時であってもよい。   The wire crimping terminal blank 11, the wire assembly and the wire harnesses 1, 1 </ b> A, 1 </ b> B according to the present embodiment are formed by crimping the wire crimping part 12 to the terminal part of the electric wire 21, and The cut region 13b-2 included in 13b is cut to form the terminal connection portion 14 and terminal protrusions 15, 16, and 17 extending from the terminal connection portion 14 in a predetermined direction. Note that the step of cutting the cut region 13b-2 included in the peripheral region 13b may be simultaneous with the step of pressing the wire crimping portion 12 to the terminal portion of the electric wire 21.

本実施の形態に係る電線圧着端子用ブランク材11、電線アッセンブリーおよびワイヤハーネス1,1A、1Bは、端子突起部15,16,17をどのような方向に延出させる場合でも、電線21の端末部に電線圧着部12を圧着させるまでの板取り部13の周辺側領域13bの形状が変わらないため、電線圧着部12が同一形状で、端子突起部15,16,17の突出方向が相違する電線圧着端子とする前のブランク材の段階で予め各種の評価試験をクリアしておけば、新規に電線圧着端子が必要になったときには、ブランク材に対して多大な評価工数および費用が発生せず、ブランク材の種類が増加することがない。   The wire crimping terminal blank 11, the wire assembly, and the wire harnesses 1, 1 </ b> A, and 1 </ b> B according to the present embodiment can end the wire 21 regardless of the direction in which the terminal protrusions 15, 16, and 17 extend. Since the shape of the peripheral region 13b of the plate take-up portion 13 is not changed until the wire crimping portion 12 is crimped to the portion, the wire crimping portion 12 has the same shape and the protruding directions of the terminal protrusions 15, 16, 17 are different. If various evaluation tests are cleared in advance at the stage of the blank material before making the wire crimping terminal, when a new wire crimping terminal becomes necessary, a large amount of evaluation man-hours and costs are generated for the blank material. The type of blank material does not increase.

本実施の形態に係る電線アッセンブリーは、第1の電線保持部12aを電線21の端末部先端の導線21aに重ねて包んだ状態に圧着させるとともに、第2の電線保持部12bを電線21の端末部の絶縁被覆材21bが皮剥ぎされていない部分に重ねて包んだ状態に圧着させるが、板取り部13の周辺側領域13bに含まれる切除領域13b−2を切除させていない。   The electric wire assembly according to the present embodiment crimps the first electric wire holding portion 12a so as to be wrapped and wrapped around the conducting wire 21a at the end of the terminal portion of the electric wire 21, and the second electric wire holding portion 12b is connected to the end of the electric wire 21. The insulating covering material 21b of the part is crimped in a state where it is overlapped and wrapped on the part that is not peeled off, but the excision region 13b-2 included in the peripheral side region 13b of the plate cutting part 13 is not excised.

本実施の形態に係る電線アッセンブリーは、電線圧着端子用ブランク材11の電線圧着部12に電線21の端末部が圧着済みであるため、板取り部13の周辺側領域13bに含まれる切除領域13b−2を切除するだけでアッセンブリーを出荷することができ、電線圧着端子用ブランク材11の在庫が過剰にならない。   In the electric wire assembly according to the present embodiment, since the terminal portion of the electric wire 21 has been crimped to the electric wire crimping portion 12 of the wire crimping terminal blank 11, the cut region 13 b included in the peripheral region 13 b of the plate cutting portion 13. The assembly can be shipped simply by excising -2, and the stock of the wire crimp terminal blanks 11 does not become excessive.

以上説明したように、本発明の電線圧着端子用ブランク材、電線アッセンブリーおよびワイヤハーネスの製造方法は、端子突起部をどのような方向に延出させる場合でも、電線の端末部に電線圧着部を圧着させるまでの板取り部の周辺側領域の形状が変わらないため、電線圧着部が同一形状で、端子突起部の突出方向が相違する電線圧着端子とする前のブランク材の段階で予め各種の評価試験をクリアしておけば、新規に電線圧着端子が必要になったときには、ブランク材に対して多大な評価工数および費用が発生せず、ブランク材の種類が増加することがないという効果を有し、電線圧着端子用ブランク材、電線アッセンブリーおよびワイヤハーネスの製造方法の全般に有用である。   As described above, the manufacturing method of the wire crimping terminal blank material, the wire assembly, and the wire harness of the present invention provides the wire crimping portion at the terminal portion of the wire, regardless of the direction in which the terminal protrusion is extended. Since the shape of the peripheral side area of the plate take-up part until crimping does not change, the wire crimping part is of the same shape, and various kinds of materials are used in advance at the stage of the blank material before making the wire crimping terminal different in the protruding direction of the terminal protrusion. If the evaluation test is cleared, when a new wire crimping terminal is required, there will be no significant evaluation man-hours and costs for the blank material, and the type of blank material will not increase. It is useful for the whole manufacturing method of the blank material for electric wire crimping terminals, the electric wire assembly, and the wire harness.
