Description

コネクタホルダ、端子挿入装置、およびワイヤハーネスの製造方法Connector holder, terminal insertion device, and method of manufacturing wire harness
　本発明は、コネクタを保持するコネクタホルダ、コネクタホルダを備えた端子挿入装置、および、コネクタホルダを用いたワイヤハーネスの製造方法に関する。 The present invention relates to a connector holder for holding a connector, a terminal insertion device having the connector holder, and a method for manufacturing a wire harness using the connector holder.
　複数の電線が組み合わされてなるワイヤハーネスは、自動車などの電装品の配線としてよく利用されている。例えば、端部に端子が圧着された複数の電線と、それら複数の電線の端子が取り付けられたコネクタとを備えたワイヤハーネスが知られている。 ワ イ ヤ Wire harnesses composed of multiple electric wires are often used as wiring for electrical components such as automobiles. For example, there is known a wire harness including a plurality of electric wires whose terminals are crimped to ends and a connector to which the terminals of the plurality of electric wires are attached.
　上記のようなワイヤハーネスを製造する際に、端子をコネクタの端子孔に挿入する処理が行われる。その際に、コネクタを保持するコネクタホルダが用いられる（例えば、特許文献１参照）。コネクタホルダは、コネクタを着脱自在に保持するように構成されている。ワイヤハーネスを製造する際には、まず、複数の端子孔が形成されたコネクタをコネクタホルダに装着する。そして、電線を一本ずつ把持しながらコネクタに向けて移動させ、電線の先端に設けられた端子を端子孔に挿入していく。予め定められた数の電線の端子を挿入し終えると、コネクタをコネクタホルダから取り外す。 処理 When manufacturing the above-described wire harness, a process of inserting a terminal into a terminal hole of a connector is performed. At that time, a connector holder that holds the connector is used (for example, see Patent Document 1). The connector holder is configured to detachably hold the connector. When manufacturing a wire harness, first, a connector having a plurality of terminal holes is mounted on a connector holder. Then, the wires are moved toward the connector while grasping the wires one by one, and the terminals provided at the ends of the wires are inserted into the terminal holes. When the predetermined number of electric wire terminals have been inserted, the connector is removed from the connector holder.
　図１５は、従来のコネクタホルダの一例を示す縦断面図である。コネクタホルダ２３０にはホルダ孔２４０が形成されており、このホルダ孔２４０にコネクタ２００が挿入されている。コネクタ２００には、端子２５０が挿入される複数の端子孔２０１が形成されている。コネクタ２００の背面２１０は、コネクタホルダ２３０のホルダ孔２４０の奥側の面２３５に当接している。 FIG. 15 is a longitudinal sectional view showing an example of a conventional connector holder. The connector holder 230 has a holder hole 240 formed therein, and the connector 200 is inserted into the holder hole 240. The connector 200 has a plurality of terminal holes 201 into which the terminals 250 are inserted. The back surface 210 of the connector 200 is in contact with the surface 235 on the back side of the holder hole 240 of the connector holder 230.

　電線２２０を把持しながらコネクタ２００の方に押し込むと、端子孔２０１に端子２５０を挿入することができる。この際、押し込み量が少ないと、図１６に示すように、端子２５０は端子孔２０１に十分に挿入されず、取り付け不良が生じてしまう。一方、押し込み量が多いと、図１７に示すように、電線２２０の一部２２５が曲がってしまい、電線２２０が座屈してしまう。その結果、電線２２０の品質が低下してしまう。 (4) When the electric wire 220 is pressed toward the connector 200 while being gripped, the terminal 250 can be inserted into the terminal hole 201. At this time, if the pushing amount is small, the terminal 250 is not sufficiently inserted into the terminal hole 201 as shown in FIG. On the other hand, when the pushing amount is large, as shown in FIG. 17, a part 225 of the electric wire 220 is bent, and the electric wire 220 buckles. As a result, the quality of the electric wire 220 deteriorates.
　そこで、押し込み量を検出するセンサを設け、そのセンサの検出値に基づいて押し込み量を調整することが考えられる。しかし、そのようなセンサを設けることとすると、装置の構成が複雑化してしまう。また、コストアップの原因となる。 Therefore, it is conceivable to provide a sensor for detecting the amount of depression and adjust the amount of depression based on the detection value of the sensor. However, providing such a sensor complicates the configuration of the device. In addition, it causes an increase in cost.
　本発明はかかる点に鑑みてなされたものであり、その目的は、構成の複雑化およびコストアップを抑えつつ、電線の品質を低下させずに端子をコネクタに良好に挿入することを可能にするコネクタホルダ、端子挿入装置、および、ワイヤハーネスの製造方法を提供することである。 The present invention has been made in view of such a point, and an object of the present invention is to enable a terminal to be inserted into a connector satisfactorily without deteriorating the quality of an electric wire while suppressing a complicated configuration and an increase in cost. An object of the present invention is to provide a connector holder, a terminal insertion device, and a method for manufacturing a wire harness.
　本発明に係るコネクタホルダは、コネクタが挿入される入口部と前記入口部よりも奥側に位置するコネクタ保持部とを含むホルダ孔が形成されたホルダ本体と、前記ホルダ本体に設けられ、前記コネクタが前記コネクタ保持部から前記ホルダ孔の奥側に移動すると前記コネクタに前記入口部側に向かう弾性力を付与する弾性体と、を備えている。 The connector holder according to the present invention is provided with a holder main body in which a holder hole including an entrance portion into which a connector is inserted and a connector holding portion located on the back side of the entrance portion is formed, and the holder main body is provided with the And an elastic body for applying an elastic force toward the inlet portion to the connector when the connector moves from the connector holding portion to the back side of the holder hole.
　上記コネクタホルダによれば、ホルダ本体のホルダ孔に入口部からコネクタを挿入することにより、コネクタをホルダ孔のコネクタ保持部に保持することができる。そして、電線を把持しながらコネクタの方に押し込むことにより、電線の先端に設けられた端子をコネクタに挿入することができる。これにより、端子付き電線をコネクタに取り付けることができる。この際、電線の押し込み量が多くても、コネクタは端子に押されて、ホルダ孔のコネクタ保持部から奥側に移動する。よって、電線の長手方向に無理な圧縮力が加わることを防止することができ、電線の座屈を防止することができる。一方、コネクタがコネクタ保持部から奥側に移動すると、コネクタは弾性体により入口部側に向かう弾性力を受ける。そのため、コネクタが弾性力を受けるまで端子をコネクタに押し込むことによって、押し込み量不足を回避することができ、取り付け不良を防止することができる。上記コネクタホルダによれば、押し込み量を検出するセンサは不要である。したがって、構成の複雑化およびコストアップを抑えつつ、電線の品質を低下させずに端子をコネクタに良好に挿入することができる。 According to the above connector holder, the connector can be held in the connector holding portion of the holder hole by inserting the connector from the entrance into the holder hole of the holder body. Then, by pushing the wire toward the connector while holding the wire, the terminal provided at the end of the wire can be inserted into the connector. Thereby, the terminal-equipped electric wire can be attached to the connector. At this time, even if the wire is pushed in by a large amount, the connector is pushed by the terminal and moves from the connector holding portion of the holder hole to the back side. Therefore, it is possible to prevent an unreasonable compressive force from being applied in the longitudinal direction of the electric wire, and to prevent buckling of the electric wire. On the other hand, when the connector moves from the connector holding portion to the back side, the connector receives an elastic force toward the entrance portion by the elastic body. Therefore, by pushing the terminal into the connector until the connector receives the elastic force, it is possible to avoid shortage of the pushing amount, and it is possible to prevent poor mounting. According to the connector holder, a sensor for detecting the pushing amount is unnecessary. Therefore, it is possible to satisfactorily insert the terminal into the connector without deteriorating the quality of the electric wire, while suppressing the complexity and cost of the configuration.
　本発明の好ましい一態様によれば、前記ホルダ孔は、前記コネクタ保持部よりも奥側に位置する奥部を含んでいる。前記コネクタホルダは、前記ホルダ孔の前記奥部に配置され、前記ホルダ孔の前記入口部側に位置する表面と、前記弾性体側に位置する裏面とを有するピストンを備えている。前記ホルダ孔の前記コネクタ保持部と前記奥部との間に、前記ピストンの前記表面と当接することにより前記ピストンが前記入口部側へ移動することを規制するストッパ部が設けられている。 According to a preferred aspect of the present invention, the holder hole includes a back portion located on a back side of the connector holding portion. The connector holder includes a piston disposed at the back of the holder hole and having a front surface located on the inlet side of the holder hole and a back surface located on the elastic body side. A stopper portion is provided between the connector holding portion and the back portion of the holder hole, the stopper portion restricting the piston from moving toward the inlet portion by abutting on the surface of the piston.
　上記態様によれば、ピストンは弾性体からホルダ孔の入口部側に向かう弾性力を受けているが、ピストンの表面がストッパ部に当接すると、ピストンの入口部側への移動は規制される。そのため、コネクタは、コネクタ保持部に保持されているときには、弾性体の弾性力を受けない。よって、コネクタをコネクタ保持部に保持することができる。一方、コネクタが端子に押されてホルダ孔の奥部の方に移動すると、ピストンはコネクタに押されて奥部の方に移動する。すると、ピストンに押されて弾性体が縮むことにより、弾性体はピストンを介してコネクタに入口部側に向かう弾性力を付与する。このように、上記態様によれば、コネクタの奥部側への移動を許容しつつ、コネクタ保持部よりも入口部側への移動を規制することができ、コネクタをコネクタ保持部において良好に保持することができる。 According to the above aspect, the piston receives the elastic force from the elastic body toward the inlet of the holder hole, but when the surface of the piston contacts the stopper, the movement of the piston toward the inlet is restricted. . Therefore, when the connector is held by the connector holding portion, the connector does not receive the elastic force of the elastic body. Therefore, the connector can be held by the connector holding portion. On the other hand, when the connector is pushed by the terminal and moves toward the back of the holder hole, the piston is pushed by the connector and moves toward the back. Then, the elastic body contracts by being pushed by the piston, so that the elastic body applies an elastic force toward the inlet side to the connector via the piston. As described above, according to the above aspect, it is possible to restrict the movement of the connector to the inlet side than the connector holding portion while allowing the connector to move to the back side, and to hold the connector in the connector holding portion satisfactorily. can do.
　本発明の好ましい一態様によれば、前記コネクタホルダは、前記ピストンに取り付けられ、前記コネクタに前記ホルダ孔の前記入口部側に向かう弾性力を付与する補助弾性体を備えている。前記補助弾性体の弾性力は、前記弾性体の弾性力よりも小さく設定されている。 According to a preferred aspect of the present invention, the connector holder includes an auxiliary elastic body attached to the piston and applying an elastic force to the connector toward the inlet of the holder hole. The elastic force of the auxiliary elastic body is set smaller than the elastic force of the elastic body.
　上記態様によれば、ホルダ孔からコネクタを引き抜く際に、補助弾性体がコネクタをホルダ孔の入口部側に押すので、より小さな力でコネクタを引き抜くことができる。よって、コネクタホルダからコネクタを取り出す作業が容易となる。なお、補助弾性体の弾性力は弾性体の弾性力よりも小さく設定されているので、弾性体の前述の機能を損なうことはない。 According to the above aspect, when the connector is pulled out from the holder hole, the auxiliary elastic body pushes the connector toward the entrance of the holder hole, so that the connector can be pulled out with a smaller force. Therefore, the operation of taking out the connector from the connector holder becomes easy. Since the elastic force of the auxiliary elastic body is set smaller than the elastic force of the elastic body, the above-described function of the elastic body is not impaired.
　本発明の好ましい一態様によれば、前記弾性体は、前記ホルダ孔の前記奥部に配置されたコイルバネである。 According to a preferred aspect of the present invention, the elastic body is a coil spring disposed at the back of the holder hole.
　上記態様によれば、弾性体として安価かつ簡単なコイルバネを用いるので、更なる構成の簡単化および低コスト化が可能となる。 According to the above aspect, since an inexpensive and simple coil spring is used as the elastic body, it is possible to further simplify the configuration and reduce the cost.
　本発明に係る端子挿入装置は、前記コネクタホルダと、先端に端子が設けられた電線を把持するクランプと、前記コネクタホルダの前記ホルダ孔に挿入されたコネクタに前記端子を挿入するように、前記クランプを少なくとも前記電線の長手方向に移動させる駆動装置と、を備えている。 The terminal insertion device according to the present invention, the connector holder, a clamp for holding an electric wire provided with a terminal at a tip, and the terminal so as to insert the terminal into the connector inserted into the holder hole of the connector holder, And a driving device for moving the clamp at least in the longitudinal direction of the electric wire.
　上記端子挿入装置によれば、駆動装置がクランプを電線の長手方向に移動させることにより、電線の先端に設けられた端子をコネクタに自動的に挿入することができる。ところで、電線および端子には個体差があるため、クランプが電線を把持して端子をコネクタに挿入するときの押し込み量には、ばらつきが生じる。人が電線を把持して端子をコネクタに挿入する場合には、人の微妙な感覚により押し込み量を微調整することができ、上記ばらつきを吸収することができる。ところが、駆動装置により駆動されるクランプでは、そのような押し込み量の微調整は難しい。しかし、上記端子挿入装置によれば、前述のコネクタホルダを備えているので、前記弾性体によって押し込み量のばらつきを吸収することができる。したがって、コネクタに対する端子の挿入を自動化した場合であっても、電線の品質を低下させずに端子をコネクタに良好に挿入することができる。 According to the terminal insertion device, the drive device moves the clamp in the longitudinal direction of the electric wire, so that the terminal provided at the end of the electric wire can be automatically inserted into the connector. By the way, since there is an individual difference between the electric wire and the terminal, the amount of pushing when the clamp grips the electric wire and inserts the terminal into the connector varies. When a person grasps the electric wire and inserts the terminal into the connector, the pushing amount can be finely adjusted by a subtle feeling of the person, and the above-described variation can be absorbed. However, such fine adjustment of the pushing amount is difficult with a clamp driven by a driving device. However, according to the terminal insertion device, since the above-described connector holder is provided, it is possible to absorb variations in the pushing amount by the elastic body. Therefore, even when the terminal insertion into the connector is automated, the terminal can be inserted into the connector satisfactorily without deteriorating the quality of the electric wire.
　本発明に係るワイヤハーネスの製造方法は、前記コネクタホルダを準備する工程と、前記コネクタホルダの前記ホルダ孔に、端子孔が形成されたコネクタを挿入する工程と、先端に端子が設けられた電線を把持する工程と、前記電線の長手方向に沿って前記電線を移動させることにより、前記コネクタの前記端子孔に前記端子を挿入する工程と、前記コネクタホルダから前記コネクタを引き抜く工程と、を包含している。 The method for manufacturing a wire harness according to the present invention includes a step of preparing the connector holder, a step of inserting a connector having a terminal hole into the holder hole of the connector holder, and an electric wire having a terminal at a tip. Gripping, moving the electric wire along the longitudinal direction of the electric wire, inserting the terminal into the terminal hole of the connector, and pulling out the connector from the connector holder. are doing.
　上記製造方法により、製造装置の構成の複雑化およびコストアップを抑えつつ、品質の高いワイヤハーネスを良好に製造することができる。 According to the above-described manufacturing method, a high-quality wire harness can be satisfactorily manufactured while suppressing complication of the configuration of the manufacturing apparatus and increase in cost.
　本発明によれば、構成の複雑化およびコストアップを抑えつつ、電線の品質を低下させずに端子をコネクタに良好に挿入することを可能にするコネクタホルダ、端子挿入装置、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。 Advantageous Effects of Invention According to the present invention, a connector holder, a terminal insertion device, and a wire harness that enable a terminal to be properly inserted into a connector without deteriorating the quality of an electric wire while suppressing complexity and cost of the configuration.

Flows. By detecting the current, the energization sensor 38 detects that the terminal 12 is pressed against the first correction front surface 31A and the second correction front surface 32A and the posture is corrected.

The cross-sectional shape perpendicular to the front-rear direction of the inlet portion 63 and the connector holding portion 64 is formed in a shape suitable for the cross-sectional shape of the connector 20. Here, since the cross-sectional shape of the connector 20 is square, the entrance 63 is formed of a square opening, and the connector holding portion 64 is formed of a hole having a square cross-section. On the other hand, the cross-sectional shape of the back portion 65 does not necessarily have to be a shape that matches the cross-sectional shape of the connector 20.

　奥部６５には、ピストン７６と、弾性体の一例であるコイルバネ７５とが配置されている。ピストン７６は奥部６５の横断面形状に適合した形状に形成されている。本実施形態では奥部６５は円孔からなっており、ピストン７６は円板により形成されている。ピストン７６は、入口部６３側に位置する表面７６Ａと、コイルバネ７５側に位置する裏面７６Ｂとを有している。 ピ ス ト ン A piston 76 and a coil spring 75, which is an example of an elastic body, are arranged in the back part 65.

The piston 76 has a front surface 76A located on the inlet 63 side and a rear surface 76B located on the coil spring 75 side.
　コイルバネ７５は、ホルダ孔６１の奥部６５に配置されている。詳しくは、コイルバネ７５は、ホルダ孔６１の奥側の面６７とピストン７６の裏面７６Ｂとの間に配置されている。ここでは、コイルバネ７５は圧縮された状態で配置されている。なお、ピストン７６の裏面７６Ｂには、コイルバネ７５を位置決めするボス部材７７が設けられている。ボス部材７７は、コイルバネ７５の内側に配置されている。ただし、ボス部材７７はなくてもよい。コイルバネ７５とピストン７６の裏面７６Ｂとは固定されていてもよく、単に接触しているだけでもよい。同様に、コイルバネ７５とホルダ孔６１の奥側の面６７とは固定されていてもよく、単に接触しているだけでもよい。 The coil spring 75 is disposed in the back part 65 of the holder hole 61. More specifically, the coil spring 75 is disposed between the back surface 67 of the holder hole 61 and the back surface 76B of the piston 76. Here, the coil spring 75 is arranged in a compressed state. A boss member 77 for positioning the coil spring 75 is provided on the back surface 76B of the piston 76. The boss member 77 is arranged inside the coil spring 75. However, the boss member 77 may not be provided.

Similarly, the coil spring 75 and the inner surface 67 of the holder hole 61 may be fixed, or may simply be in contact with each other.
　ピストン７６には、補助弾性体の一例であるプランジャ７８が取り付けられている。プランジャ７８は、ピストン７６およびボス部材７７の中心部分を貫通している。プランジャ７８は、シリンダ７８Ｂと、シリンダ７８Ｂにスライド自在に設けられたピン７８Ａとを有している。ピン７８Ａの少なくとも一部は、ピストン７６よりも入口部６３側に配置されている。言い換えると、ピン７８Ａの少なくとも一部は、ピストン７６の表面７６Ａから入口部６３側に突出している。シリンダ７８Ｂの内部には、ピン７８Ａに対して入口部６３側に向かう弾性力を付与するバネが配置されているか、または、ピン７８Ａに対して入口部６３側に向かう弾性力を付与する圧縮性流体（例えば空気）が封入されている。プランジャ７８の弾性力は、コイルバネ７５の弾性力よりも小さく設定されている。 プ ラ ン A plunger 78, which is an example of an auxiliary elastic body, is attached to the piston 76. The plunger 78 penetrates through a central portion of the piston 76 and the boss member 77. The plunger 78 has a cylinder 78B and a pin 78A slidably provided on the cylinder 78B. At least a part of the pin 78A is disposed closer to the inlet 63 than the piston 76 is. In other words, at least a portion of the pin 78A protrudes from the surface 76A of the piston 76 toward the inlet 63. A spring is provided inside the cylinder 78B to apply an elastic force toward the inlet portion 63 to the pin 78A, or a compressive force is applied to apply an elastic force toward the inlet portion 63 to the pin 78A. A fluid (for example, air) is enclosed. The elastic force of the plunger 78 is set smaller than the elastic force of the coil spring 75.

　以上が端子挿入装置２の構成である。次に、コネクタホルダ６０を利用してワイヤハーネスを製造する方法について説明する。 The above is the configuration of the terminal insertion device 2. Next, a method of manufacturing a wire harness using the connector holder 60 will be described.
　図５は、本実施形態に係るワイヤハーネスの製造方法に関するフローチャートである。本実施形態に係るワイヤハーネスの製造方法は、コネクタホルダ６０を準備する工程（ステップＳ１）と、コネクタホルダ６０のホルダ孔６１にコネクタ２０を挿入する工程（ステップＳ２）と、電線１１を把持する工程（ステップＳ３）と、コネクタ２０の端子孔２１に端子１２を挿入する工程（ステップＳ４）と、端子１２が挿入された電線の本数が所定本数に達したか否かを判定する工程（ステップＳ５）と、コネクタホルダ６０からコネクタ２０を引き抜く工程（ステップＳ６）とを包含している。 FIG. 5 is a flowchart relating to the method for manufacturing a wire harness according to the present embodiment. In the method for manufacturing the wire harness according to the present embodiment, a step of preparing the connector holder 60 (step S1), a step of inserting the connector 20 into the holder hole 61 of the connector holder 60 (step S2), and holding the electric wire 11 A step (step S3), a step of inserting the terminal 12 into the terminal hole 21 of the connector 20 (step S4), and a step of determining whether or not the number of wires into which the terminal 12 has been inserted has reached a predetermined number (step S3). S5) and a step of pulling out the connector 20 from the connector holder 60 (step S6).
　まず、コネクタホルダ６０を準備し、図６および図７に示すように、コネクタ２０をコネクタホルダ６０のホルダ孔６１に挿入する。これにより、コネクタ２０はホルダ孔６１のコネクタ保持部６４（図４参照）に保持される。この際、プランジャ７８のピン７８Ａは奥側に押される。しかし、プランジャ７８の弾性力は小さいため、プランジャ７８によってコネクタ２０がコネクタ保持部６４から押し出されることはない。 First, the connector holder 60 is prepared, and the connector 20 is inserted into the holder hole 61 of the connector holder 60 as shown in FIGS. Thereby, the connector 20 is held by the connector holding portion 64 (see FIG. 4) of the holder hole 61. At this time, the pin 78A of the plunger 78 is pushed to the back. However, since the elastic force of the plunger 78 is small, the connector 20 is not pushed out of the connector holding portion 64 by the plunger 78.
　次に、図１に示すように、作業者が電線１１を摘まみながら前方に移動させ、電線１１の先端に設けられた端子１２を、端子姿勢矯正具３０の第１矯正面３１Ａおよび第２矯正面３２Ａに押し当てる。これにより、端子１２の姿勢が矯正される。また、第１電極３１と第２電極３２とが端子１２を介して導通され、通電センサ３８から制御装置１００に信号Ｐ１が送られる（図３参照）。 Next, as shown in FIG. 1, the operator moves the terminal 11 provided at the front end of the electric wire 11 by grasping the electric wire 11 and holding the terminal 12 at the front end of the terminal posture correcting tool 30 and the second correction front surface 31 </ b> A. Press against the corrective front 32A. Thereby, the posture of the terminal 12 is corrected. In addition, the first electrode 31 and the second electrode 32 are electrically connected via the terminal 12, and the signal P1 is sent from the conduction sensor 38 to the control device 100 (see FIG. 3).
　制御装置１００は、信号Ｐ１を受信するとアクチュエータ７１を駆動し、位置決めクランプ４１を閉じる。それにより、電線１１は位置決めクランプ４１に把持される。次に、制御装置１００は、第３駆動機構４５Ｃを駆動することにより移動クランプ４２を下降させ、アクチュエータ７２を駆動することにより移動クランプ４２を閉じる。これにより、電線１１は移動クランプ４２により把持される（ステップＳ３）。移動クランプ４２が電線１１を把持した後、制御装置１００はアクチュエータ７１を駆動し、位置決めクランプ４１を開く。 When the control device 100 receives the signal P1, the control device 100 drives the actuator 71 and closes the positioning clamp 41. Thereby, the electric wire 11 is gripped by the positioning clamp 41. Next, the control device 100 lowers the moving clamp 42 by driving the third driving mechanism 45C, and closes the moving clamp 42 by driving the actuator 72. Thereby, the electric wire 11 is gripped by the moving clamp 42 (Step S3). After the moving clamp 42 grips the electric wire 11, the control device 100 drives the actuator 71 to open the positioning clamp 41.
　次に、制御装置１００は、移動クランプ４２をコネクタ２０の手前の位置まで移動させる。まず、制御装置１００は第１駆動機構４５Ａを駆動し、移動クランプ４２を上向きに移動させる。この際、電線１１の先端に圧着された端子１２は第１通過センサ５１を通過し、その通過が検出される。電線１１に上下方向の曲がりが生じている場合、端子１２の上下方向の位置と移動クランプ４２の上下方向の位置との間にずれが生じる。よって、第１通過センサ５１が端子１２の通過を検出したときの移動クランプ４２の位置に基づいて、端子１２の上下方向の位置ずれ量を算出することができる。 Next, the control device 100 moves the moving clamp 42 to a position before the connector 20. First, the control device 100 drives the first drive mechanism 45A to move the moving clamp 42 upward. At this time, the terminal 12 crimped to the tip of the electric wire 11 passes through the first passage sensor 51, and the passage is detected. When the electric wire 11 is bent in the vertical direction, a deviation occurs between the vertical position of the terminal 12 and the vertical position of the movable clamp 42. Therefore, the vertical displacement of the terminal 12 can be calculated based on the position of the movable clamp 42 when the first passage sensor 51 detects the passage of the terminal 12.
　次に、制御装置１００は第２駆動機構４５Ｂを駆動し、移動クランプ４２を左向きに移動させる。この際、端子１２は第２通過センサ５２を通過し、その通過が検出される。電線１１に左右方向の曲がりが生じている場合、端子１２の左右方向の位置と移動クランプ４２の左右方向の位置との間にずれが生じる。よって、第２通過センサ５２が端子１２の通過を検出したときの移動クランプ４２の位置に基づいて、端子１２の左右方向の位置ずれ量を算出することができる。 Next, the control device 100 drives the second drive mechanism 45B to move the moving clamp 42 leftward. At this time, the terminal 12 passes through the second passage sensor 52, and the passage is detected. When the electric wire 11 is bent in the left-right direction, a deviation occurs between the position of the terminal 12 in the left-right direction and the position of the movable clamp 42 in the left-right direction. Therefore, the amount of displacement of the terminal 12 in the left-right direction can be calculated based on the position of the movable clamp 42 when the second passage sensor 52 detects the passage of the terminal 12.
　制御装置１００は、端子１２の上下方向および左右方向の位置ずれ量に基づいて移動クランプ４２の位置を補正し、移動クランプ４２を補正後の位置に移動させる。これにより、端子１２は、コネクタ２０の端子孔２１の位置に見合った位置に移動する。すなわち、端子１２は、端子孔２１の真正面に位置づけられる。 The control device 100 corrects the position of the moving clamp 42 based on the amount of displacement of the terminal 12 in the vertical and horizontal directions, and moves the moving clamp 42 to the corrected position. As a result, the terminal 12 moves to a position corresponding to the position of the terminal hole 21 of the connector 20. That is, the terminal 12 is positioned directly in front of the terminal hole 21.
　次に、制御装置１００は、第３駆動機構４５Ｃを駆動し、図８および図９に示すように、移動クランプ４２を前向きに移動させる。これにより、図１０および図１１に示すように、端子１２は端子孔２１に挿入される（ステップＳ４）。この際、図８に示すように端子孔２１の長さをＬとすると、制御装置１００は、移動クランプ４２を前向きに長さＬ以上移動させる。言い換えると、制御装置１００は、端子１２がコネクタ２０の端子孔２１の奥側の面２１ａに当接するまで移動クランプ４２を前向きに移動させる。その結果、端子１２は端子孔２１に十分に挿入される。 Next, the control device 100 drives the third drive mechanism 45C to move the moving clamp 42 forward as shown in FIGS. 8 and 9. Thereby, as shown in FIGS. 10 and 11, the terminal 12 is inserted into the terminal hole 21 (Step S4). At this time, assuming that the length of the terminal hole 21 is L as shown in FIG. 8, the control device 100 moves the moving clamp 42 forward by the length L or more. In other words, the control device 100 moves the moving clamp 42 forward until the terminal 12 comes into contact with the rear surface 21 a of the terminal hole 21 of the connector 20. As a result, the terminal 12 is sufficiently inserted into the terminal hole 21.
　本実施形態に係るコネクタホルダ６０によれば、ホルダ孔６１はコネクタ保持部６４の奥側に奥部６５を有している。そのため、コネクタ２０はコネクタ保持部６４よりも奥側に移動可能である。端子１２がコネクタ２０の端子孔２１の奥側の面２１ａに当接した後、移動クランプ４２が更に前向きに移動すると、コネクタ２０は端子１２に押されてホルダ孔６１の奥側に移動する。言い換えると、コネクタ２０は前方に移動する。そのため、電線１１の長手方向に過大な圧縮力が加わることを避けることができ、電線１１が座屈してしまうことを防止することができる。 According to the connector holder 60 according to the present embodiment, the holder hole 61 has the back part 65 on the back side of the connector holding part 64. Therefore, the connector 20 can be moved to the back side of the connector holding portion 64. When the movable clamp 42 moves further forward after the terminal 12 comes into contact with the surface 21 a on the far side of the terminal hole 21 of the connector 20, the connector 20 is pushed by the terminal 12 and moves to the far side of the holder hole 61. In other words, the connector 20 moves forward. Therefore, it is possible to avoid applying an excessive compressive force in the longitudinal direction of the electric wire 11, and it is possible to prevent the electric wire 11 from buckling.
　その後、制御装置１００はアクチュエータ７２を駆動し、移動クランプ４２を開く。これにより、移動クランプ４２による電線の把持が解除される。移動クランプ４２による電線の把持が解除されると、コイルバネ７５から入口部６３側に向かう弾性力を受けているピストン７６は、表面７６Ａがストッパ部６６に当接するまで入口部６３側に移動する。その結果、コネクタ２０は入口部６３側に移動し、図１２に示すようにコネクタ保持部６４に保持される。 Thereafter, the control device 100 drives the actuator 72 to open the moving clamp 42. Thereby, the gripping of the electric wire by the moving clamp 42 is released. When the gripping of the electric wire by the moving clamp 42 is released, the piston 76 receiving the elastic force from the coil spring 75 toward the inlet 63 moves to the inlet 63 until the surface 76A contacts the stopper 66. As a result, the connector 20 moves to the entrance portion 63 side and is held by the connector holding portion 64 as shown in FIG.
　その後、制御装置１００は、第１～第３駆動機構４５Ａ～４５Ｃを駆動し、移動クランプ４２を初期位置（図１に示す位置）に移動させる。端子１２が挿入された端子付き電線１０の本数が所定本数に達していないと判定されると（ステップＳ５）、次の端子付き電線１０の端子１２を他の端子孔２１に挿入すべく、上述の処理を繰り返す。このような処理は、コネクタ２０に装着される端子付き電線１０の数だけ繰り返される。これにより、コネクタ２０に複数本の端子付き電線１０を装着することができる。 After that, the control device 100 drives the first to third drive mechanisms 45A to 45C to move the movable clamp 42 to the initial position (the position shown in FIG. 1). If it is determined that the number of electric wires with terminals 10 into which the terminals 12 have been inserted does not reach the predetermined number (step S5), the above-described operation is performed to insert the terminal 12 of the next electric wire with terminals 10 into another terminal hole 21. Is repeated. Such a process is repeated by the number of electric wires 10 with terminals attached to the connector 20. Thereby, a plurality of electric wires with terminals 10 can be attached to connector 20.
　コネクタ２０に複数本の端子付き電線１０を装着した後は、図１３に示すように、電線１１を後方に引っ張ることにより、ホルダ孔６１からコネクタ２０を取り出す（ステップＳ６）。本実施形態では、コネクタ２０はプランジャ７８から入口部６３側への弾性力を受けているので、より小さな力でコネクタ２０を引き抜くことができる。よって、電線１１を大きな力で引っ張る必要がなく、電線１１の品質を良好に保つことができる。 After the plurality of electric wires 10 with terminals are attached to the connector 20, as shown in FIG. 13, the electric wire 11 is pulled backward to take out the connector 20 from the holder hole 61 (step S6). In this embodiment, since the connector 20 receives the elastic force from the plunger 78 toward the inlet 63, the connector 20 can be pulled out with a smaller force. Therefore, it is not necessary to pull the electric wire 11 with a large force, and the quality of the electric wire 11 can be kept good.
　以上のようにして、複数本の端子付き電線１０が組み合わせられたワイヤハーネスを製造することができる。 As described above, a wire harness in which a plurality of electric wires with terminals 10 are combined can be manufactured.
　次に、本実施形態によってもたされる様々な効果について説明する。 Next, various effects provided by the present embodiment will be described.
　本実施形態に係るコネクタホルダ６０によれば、ホルダ本体６２のホルダ孔６１に入口部６３からコネクタ２０を挿入することにより、コネクタ２０をホルダ孔６１のコネクタ保持部６４に保持することができる。そして、電線１１を把持しながらコネクタ２０の方に押し込むことにより、電線１１の先端に設けられた端子１２をコネクタ２０の端子孔２１に挿入することができる。これにより、端子付き電線１０をコネクタ２０に取り付けることができる。この際、電線１１の押し込み量が多くても、コネクタ２０は端子１２に押されて、ホルダ孔６１のコネクタ保持部６４から奥部６５の方に移動する。よって、電線１１の長手方向に無理な圧縮力が加わることを防止することができ、電線１１の座屈を防止することができる。一方、コネクタ２０がコネクタ保持部６４から奥部６５の方に移動すると、コネクタ２０はコイルバネ７５により入口部６３側に向かう弾性力を受ける。そのため、コネクタ２０が弾性力を受けるまで端子１２をコネクタ２０に押し込むことによって、押し込み量不足を回避することができ、取り付け不良を防止することができる。本実施形態に係るコネクタホルダ６０によれば、端子１２の押し込み量を検出するセンサは不要である。したがって、構成の複雑化およびコストアップを抑えつつ、電線１１の品質を低下させずに端子１２をコネクタ２０に良好に挿入することができる。 According to the connector holder 60 according to the present embodiment, the connector 20 can be held in the connector holding portion 64 of the holder hole 61 by inserting the connector 20 into the holder hole 61 of the holder main body 62 from the entrance 63. Then, by pushing the wire 11 toward the connector 20 while holding the wire 11, the terminal 12 provided at the end of the wire 11 can be inserted into the terminal hole 21 of the connector 20. Thereby, the electric wire with terminal 10 can be attached to the connector 20. At this time, even if the wire 11 is pushed in by a large amount, the connector 20 is pushed by the terminal 12 and moves from the connector holding portion 64 of the holder hole 61 toward the back portion 65. Therefore, it is possible to prevent an unreasonable compressive force from being applied in the longitudinal direction of the electric wire 11 and to prevent the electric wire 11 from buckling. On the other hand, when the connector 20 moves from the connector holding portion 64 to the back portion 65, the connector 20 receives an elastic force toward the inlet portion 63 by the coil spring 75. For this reason, by pushing the terminal 12 into the connector 20 until the connector 20 receives the elastic force, it is possible to avoid a shortage of the pushing amount, and to prevent a mounting failure. According to the connector holder 60 according to the present embodiment, a sensor for detecting the pushing amount of the terminal 12 is unnecessary. Therefore, it is possible to satisfactorily insert the terminal 12 into the connector 20 without deteriorating the quality of the electric wire 11 while suppressing the complexity and cost of the configuration.
　ピストン７６はコイルバネ７５からホルダ孔６１の入口部６３側に向かう弾性力を受けているが、ピストン７６の表面７６Ａがストッパ部６６に当接すると、ピストン７６の入口部６３側への移動は規制される。そのため、コネクタ２０は、コネクタ保持部６４に保持されているときには、コイルバネ７５の弾性力を受けない。よって、コネクタ２０をコネクタ保持部６４に保持することができる。一方、コネクタ２０が端子１２に押されてホルダ孔６１の奥部６５の方に移動すると、ピストン７６はコネクタ２０に押されて奥部６５の方に移動する。すると、ピストン７６に押されてコイルバネ７５が縮むことにより、コイルバネ７５はピストン７６を介してコネクタ２０に入口部６３側に向かう弾性力を付与する。このように、本実施形態によれば、コネクタ２０の奥部６５側への移動を許容しつつ、コネクタ保持部６４よりも入口部６３側への移動を規制することができ、コネクタ２０をコネクタ保持部６４において良好に保持することができる。 The piston 76 receives an elastic force from the coil spring 75 toward the inlet 63 of the holder hole 61. When the surface 76A of the piston 76 contacts the stopper 66, the movement of the piston 76 toward the inlet 63 is restricted. Is done. Therefore, the connector 20 does not receive the elastic force of the coil spring 75 when being held by the connector holding portion 64. Therefore, the connector 20 can be held by the connector holding portion 64. On the other hand, when the connector 20 is pushed by the terminal 12 and moves toward the back 65 of the holder hole 61, the piston 76 is pushed by the connector 20 and moves toward the back 65. Then, the coil spring 75 is pressed by the piston 76 and contracts, so that the coil spring 75 applies an elastic force toward the inlet portion 63 to the connector 20 via the piston 76. As described above, according to the present embodiment, it is possible to restrict the movement of the connector 20 toward the entrance portion 63 than the connector holding portion 64 while allowing the movement of the connector 20 toward the back portion 65. The holding section 64 can hold the sheet satisfactorily.
　本実施形態に係るコネクタホルダ６０によれば、ホルダ孔６１からコネクタ２０を引き抜く際に、プランジャ７８がコネクタ２０をホルダ孔６１の入口部６３側に押すので、より小さな力でコネクタ２０を引き抜くことができる。電線１１を大きな力で引っ張る必要がないので、電線１１の品質を良好に保つことができる。 According to the connector holder 60 according to the present embodiment, when pulling out the connector 20 from the holder hole 61, the plunger 78 pushes the connector 20 toward the entrance 63 of the holder hole 61, so that the connector 20 is pulled out with a smaller force. Can be. Since there is no need to pull the electric wire 11 with a large force, the quality of the electric wire 11 can be kept good.
　なお、コイルバネ７５は弾性体の一例に過ぎず、弾性体はコイルバネ７５に限定されない。弾性体は、空気バネなどの他の形式のバネであってもよく、バネ以外の弾性体であってもよい。ただし、本実施形態によれば、弾性体として安価かつ簡単なコイルバネ７５を用いるので、構成を更に簡単化および低コスト化することができる。 The coil spring 75 is merely an example of an elastic body, and the elastic body is not limited to the coil spring 75. The elastic body may be another type of spring such as an air spring, or may be an elastic body other than a spring. However, according to the present embodiment, since the inexpensive and simple coil spring 75 is used as the elastic body, the configuration can be further simplified and the cost can be reduced.
　本実施形態に係る端子挿入装置２によれば、駆動装置４５が移動クランプ４２を電線１１の長手方向に移動させることにより、電線１１の先端に設けられた端子１２をコネクタ２０に自動的に挿入することができる。ところで、電線１１および端子１２には個体差があるため、移動クランプ４２が電線１１を把持して端子１２をコネクタ２０に挿入するときの押し込み量には、ばらつきが生じる。人が電線１１を把持して端子１２をコネクタ２０に挿入する場合には、人の微妙な感覚により押し込み量を微調整することができ、上記ばらつきを吸収することができる。ところが、駆動装置４５により駆動される移動クランプ４２では、そのような押し込み量の微調整は難しい。しかし、本実施形態に係る端子挿入装置２によれば、前述のコネクタホルダ６０を備えているので、コイルバネ７５によって押し込み量のばらつきを吸収することができる。したがって、コネクタ２０に対する端子１２の挿入を自動化した場合であっても、電線１１の品質を低下させずに端子１２をコネクタ２０に良好に挿入することができる。 According to the terminal insertion device 2 according to the present embodiment, the drive device 45 moves the moving clamp 42 in the longitudinal direction of the electric wire 11, thereby automatically inserting the terminal 12 provided at the tip of the electric wire 11 into the connector 20. can do. By the way, since there is an individual difference between the electric wire 11 and the terminal 12, the pushing amount when the moving clamp 42 grips the electric wire 11 and inserts the terminal 12 into the connector 20 varies. When a person grasps the electric wire 11 and inserts the terminal 12 into the connector 20, the pushing amount can be finely adjusted by a delicate feeling of the person, and the variation can be absorbed. However, with the moving clamp 42 driven by the driving device 45, such fine adjustment of the pushing amount is difficult. However, according to the terminal insertion device 2 according to the present embodiment, since the above-described connector holder 60 is provided, it is possible for the coil spring 75 to absorb variations in the pushing amount. Therefore, even when the insertion of the terminal 12 into the connector 20 is automated, the terminal 12 can be satisfactorily inserted into the connector 20 without deteriorating the quality of the electric wire 11.
　本実施形態に係るワイヤハーネスの製造方法によれば、前述のコネクタホルダ６０を利用するので、端子挿入装置２の構成の複雑化およびコストアップを抑えつつ、品質の高いワイヤハーネスを良好に製造することができる。 According to the method for manufacturing a wire harness according to the present embodiment, since the above-described connector holder 60 is used, a high-quality wire harness is favorably manufactured while suppressing the complexity and cost increase of the configuration of the terminal insertion device 2. be able to.
　以上、本発明の一実施形態について説明したが、前記実施形態は一例に過ぎず、本発明は前記実施形態に限定されない。他にも様々な実施形態が可能である。 Although the embodiment of the invention has been described above, the embodiment is merely an example and the invention is not limited to the embodiment. Various other embodiments are possible.
　前記実施形態では、コネクタホルダ６０はピストン７６を備えているが、ピストン７６はなくてもよい。コイルバネ７５は、コネクタ２０と接触するようになっていてもよい。 コ ネ ク タ In the above embodiment, the connector holder 60 includes the piston 76, but the piston 76 may not be provided. The coil spring 75 may come into contact with the connector 20.
　前記実施形態では、コネクタホルダ６０のホルダ孔６１は、奥側が閉じた孔である。しかし、ホルダ孔６１は、奥側が開いた孔であってもよい。例えば、ホルダ孔６１の奥部６５の前端部は前方に向けて開口し、ホルダ本体６２の前側に、コイルバネ７５を支持する支持部材が配置されていてもよい。 In the above embodiment, the holder hole 61 of the connector holder 60 is a hole whose back side is closed. However, the holder hole 61 may be a hole whose back side is open. For example, the front end of the back part 65 of the holder hole 61 may open forward, and a support member for supporting the coil spring 75 may be disposed on the front side of the holder body 62.
　ホルダ孔６１は、奥部６５を備えていなくてもよい。例えば、図１４に示すように、ホルダ本体６２の前側に、弾性体としての板バネ６８が設けられていてもよい。この場合、コネクタ２０が端子１２によって前向きに押されると、板バネ６８は前方に変形する。そして、コネクタ２０は前方に移動し、コネクタ２０の一部はホルダ孔６１から一時的に飛び出す。しかし、電線１１の把持を解除すると、板バネ６８が復元し、コネクタ２０は板バネによって後方に押され、後方に移動する。その結果、コネクタ２０はホルダ孔６１のコネクタ保持部６４に保持される。 The holder hole 61 does not have to include the inner part 65. For example, as shown in FIG. 14, a leaf spring 68 as an elastic body may be provided on the front side of the holder main body 62. In this case, when the connector 20 is pushed forward by the terminal 12, the leaf spring 68 deforms forward. Then, the connector 20 moves forward, and a part of the connector 20 temporarily jumps out of the holder hole 61. However, when the grip of the electric wire 11 is released, the leaf spring 68 is restored, and the connector 20 is pushed rearward by the leaf spring and moves rearward. As a result, the connector 20 is held by the connector holding portion 64 of the holder hole 61.
　前記実施形態の説明では、端子１２の断面形状は四角形としたが、端子１２の断面形状は四角形に限られない。また、端子１２の断面形状は多角形に限られない。例えば、端子１２の断面形状は円形であってもよい。 In the description of the above embodiment, the cross-sectional shape of the terminal 12 is a square, but the cross-sectional shape of the terminal 12 is not limited to a quadrangle. The cross-sectional shape of the terminal 12 is not limited to a polygon. For example, the cross-sectional shape of the terminal 12 may be circular.
　端子１２の姿勢を矯正する必要がない場合、端子姿勢矯正具３０はなくてもよい。また、移動クランプ４２の位置の補正が必要でない場合、第１通過センサ５１および第２通過センサ５２はなくてもよい。 When it is not necessary to correct the posture of the terminal 12, the terminal posture corrector 30 may not be provided. When the position of the moving clamp 42 does not need to be corrected, the first passage sensor 51 and the second passage sensor 52 may not be provided.
　前記実施形態では、電線１１を移動クランプ４２で把持し、移動クランプ４２を前向きに移動させることにより、端子１２をコネクタ２０の端子孔２１に挿入することとしていた。しかし、端子１２の挿入は手動で行ってもよい。すなわち、人が電線１１を把持し、電線１１を前向きに移動させることによって、端子１２をコネクタ２０の端子孔２１に挿入してもよい。 In the above embodiment, the terminal 12 is inserted into the terminal hole 21 of the connector 20 by grasping the electric wire 11 with the moving clamp 42 and moving the moving clamp 42 forward. However, the insertion of the terminal 12 may be performed manually. That is, the terminal 12 may be inserted into the terminal hole 21 of the connector 20 by grasping the electric wire 11 and moving the electric wire 11 forward.
