　電線の端部に端子を連続的に圧着する装置として、端子圧着装置（端子圧着用アプリケータ）が知られている。一般に、端子圧着装置は、連続端子（複数の端子が連ねられた帯状部材）を繰り出して定められた送出経路に沿って次々と送出する送出機構と、鉛直方向に沿って移動される圧着金型で端子を加締めて電線に圧着する圧着機構とを含んで構成されており、これら各機構が連動して圧着工程を連続的に行うようになっている（例えば、特許文献１参照）。 2.

In general, a terminal crimping apparatus is composed of a feeding mechanism that feeds continuous terminals (strip-shaped members with a plurality of terminals connected) one after another along a defined delivery path, and a crimping die that is moved along a vertical direction.

　端子圧着装置においては、圧着金型による圧着位置のばらつきを抑制してベルマウス量を均等にするため、圧着時に各端子における芯線に対する圧着部が圧着金型の真下に位置するように連続端子の載置位置を調整することになる。図４は、２つのガイド部材５０，５１により連続端子６０を規制した状態を示す概略正面図であり、図５は、図４のV-V線断面図である。この場合、図４及び図５に示すように、第１ガイド部材５０を各端子６３における芯線に対する圧着部６３における軸心方向の一端側に当接させると共に、第２ガイド部材５１を連続端子６０の連鎖体６２の外端側に当接させることにより、連続端子６０における端子６１の軸心方向への移動を規制して、各端子６１の圧着部６３を圧着金型５２の真下に案内することが考えられる。 In the terminal crimping device, in order to suppress the variation of the crimping position by the crimping die and make the bell mouth amount uniform, the crimping part of each terminal to the core wire at the time of crimping is placed directly below the crimping die. The placement position will be adjusted. 4 is a schematic front view showing a state in which the continuous terminal 60 is regulated by the two guide members 50 and 51, and FIG. 5 is a cross-sectional view taken along the line VV in FIG. In this case, as shown in FIGS. 4 and 5, the first guide member 50 is brought into contact with one end side in the axial direction of the crimping portion 63 with respect to the core wire of each terminal 63, and the second guide member 51 is connected to the continuous terminal 60. In this way, the movement of the terminal 61 in the axial direction of the continuous terminal 60 is restricted, and the crimping portion 63 of each terminal 61 is guided directly below the crimping die 52. It is possible.
　各端子６１の圧着部６３におけるベルマウス量の精度を高めるために、各端子６１の圧着部６３の寸法精度は高いが、それ以外の部分（例えば、被覆に対する圧着部６４等）は圧着部６３と比べてそれほど寸法精度が要求されていないため、連続端子６０の各端子６１において圧着部６３以外の寸法はロット毎にばらつきがある。その結果、ロット毎に圧着部６３から連鎖体６２までの寸法が変わる可能性があり、ロットを変更するたびに、連続端子６０と２つのガイド部材５０，５１との当接位置をそれぞれ調整する必要があるため、連続端子の位置決めを簡単に行うことができない。 In order to increase the accuracy of the bell mouth amount in the crimping part 63 of each terminal 61, the dimensional accuracy of the crimping part 63 of each terminal 61 is high, but the other parts (for example, the crimping part 64 etc. for the covering) are the crimping part 63. Therefore, the dimensions other than the crimping portion 63 in each terminal 61 of the continuous terminal 60 vary from lot to lot. As a result, the dimensions from the crimping part 63 to the chain 62 may change for each lot, and the contact position between the continuous terminal 60 and the two guide members 50 and 51 is adjusted each time the lot is changed. Because it is necessary, positioning of the continuous terminal cannot be performed easily.
　そこで、本発明は、連続端子の位置決めを簡単に行えることを目的とする。 Therefore, an object of the present invention is to enable easy positioning of continuous terminals.
　上記課題を解決するため、第１の態様に係る端子圧着装置は、連続端子に連ねられる複数の端子のうちの一つの端子を、圧着金型で加締めることによって、前記端子を電線に圧着する圧着機構と、前記連続端子の各端子において、前記電線の芯線に対する圧着部における軸心方向の一端側と当接させて、前記連続端子が前記軸心方向の一端側へ移動するのを規制すると共に、前記圧着金型の軸心上の位置へ前記各端子の前記圧着部を案内する第１ガイド部と、前記各端子において、前記芯線に対する前記圧着部における前記軸心方向の他端側と当接させて、前記連続端子が前記軸心方向の他端側へ移動するのを規制すると共に、前記圧着金型の軸心上の位置へ前記各端子の前記圧着部を案内する第２ガイド部とを備えている。 In order to solve the above-described problem, the terminal crimping apparatus according to the first aspect crimps the terminal to the electric wire by crimping one of the terminals connected to the continuous terminal with a crimping die. In each terminal of the crimping mechanism and the continuous terminal, it is brought into contact with one end side in the axial direction of the crimping portion with respect to the core wire of the electric wire, thereby restricting the continuous terminal from moving to one end side in the axial direction. And a first guide portion that guides the crimping portion of each terminal to a position on the axial center of the crimping die, and the other end side in the axial direction of the crimping portion with respect to the core wire in each terminal. A second guide that abuts to restrict the continuous terminal from moving to the other end side in the axial direction and guides the crimping portion of each terminal to a position on the axial center of the crimping die. Department.
　第２の態様は、第１の態様に係る端子圧着装置であって、前記第１ガイド部と前記第２ガイド部とが連結部材を介して一体的に形成されている。 A second aspect is a terminal crimping apparatus according to the first aspect, wherein the first guide part and the second guide part are integrally formed via a connecting member.
　第３の態様は、第２の態様に係る端子圧着装置であって、前記連結部材は前記各端子の前記圧着部の上面と対向する位置に配設されている。 A third aspect is a terminal crimping apparatus according to the second aspect, wherein the connecting member is disposed at a position facing the upper surface of the crimping portion of each terminal.
　第１の態様に係る端子圧着装置によると、第１ガイド部を、寸法精度の高い芯線に対する圧着部における軸心方向の一端側と当接させると共に、第２ガイド部を、寸法精度の高い芯線に対する圧着部における軸心方向の他端側と当接させることにより、連続端子の位置決めを簡単に行うことができる。また、寸法精度の高い前記圧着部を第１ガイド部と第２ガイド部とで当接させるため、ロットを変更した場合にも、連続端子と第１ガイド部及び第２ガイド部との当接位置を調整することなく、連続端子の位置決めを簡単に行うことができる。 According to the terminal crimping apparatus according to the first aspect, the first guide portion is brought into contact with one end side in the axial direction of the crimping portion with respect to the core wire having high dimensional accuracy, and the second guide portion is made to be a core wire having high dimensional accuracy. The continuous terminal can be easily positioned by bringing it into contact with the other end side in the axial direction of the crimping portion. Further, since the crimping portion having high dimensional accuracy is brought into contact with the first guide portion and the second guide portion, even when the lot is changed, the contact between the continuous terminal, the first guide portion, and the second guide portion. The continuous terminal can be easily positioned without adjusting the position.
　第２の態様によると、１つの部材で、各端子の芯線に対する圧着部における軸心方向の一端側及び他端側を当接させることができるため、第１ガイド部及び第２ガイド部の取付け誤差を低減できる。また、端子圧着装置の構成を簡単にすることができる。 According to the second aspect, since one member can abut one end side and the other end side in the axial direction of the crimping portion with respect to the core wire of each terminal, the first guide portion and the second guide portion can be attached. Error can be reduced. Further, the configuration of the terminal crimping device can be simplified.
　第３の態様によると、連結部材により連続端子が鉛直方向に移動するのを規制することができる。 According to the third aspect, it is possible to restrict the continuous terminal from moving in the vertical direction by the connecting member.

Hereinafter, the terminal crimping apparatus 1 according to the embodiment will be described. FIG. 1 is a schematic front view showing a terminal crimping apparatus 1. However, in FIG. 1, the continuous terminals are not shown for easy understanding. In addition, in FIG. 1, the direction of the arrow is the sending direction of the continuous terminal. Moreover, suppose that FIG. 2 is referred about the continuous terminal 30 and the terminal 31 connected with this.
　最初に連続端子３０について説明する。連続端子３０は、複数の端子３１が連ねられた帯状の部材であり、具体的には、帯状の連鎖帯３２の片側に複数の端子３１が等間隔で並列状に連鎖されて形成されている。各端子３１には、被覆に対する圧着部３３と、芯線に対する圧着部３４が形成されている。圧着部３４におけるベルマウス量の精度を高めるために、圧着部３４は高い寸法精度で形成されている。 First, the continuous terminal 30 will be described. The continuous terminal 30 is a band-shaped member in which a plurality of terminals 31 are connected. Specifically, a plurality of terminals 31 are formed on one side of a band-shaped chain band 32 and connected in parallel at equal intervals. . Each terminal 31 is formed with a crimping portion 33 for covering and a crimping portion 34 for core wire. In order to increase the accuracy of the bell mouth amount in the crimping portion 34, the crimping portion 34 is formed with high dimensional accuracy.
　ここで、ベルマウスとは、圧着接続を行う際、電線の径方向の圧縮圧力を除々に軽減し、圧着部３４での断線を防ぐために圧着部３４の端を若干膨らませた部分のことをいう。なお、各端子３１において圧着部３４以外の部分に関しては、圧着部３４と比べて高い寸法精度が要求されていないため、圧着部３４ほど高い寸法精度では形成されていない。 Here, the bell mouth refers to a portion in which the end of the crimping portion 34 is slightly swollen in order to gradually reduce the compression pressure in the radial direction of the electric wire and prevent disconnection at the crimping portion 34 when performing the crimping connection. . Note that portions other than the crimping portion 34 in each terminal 31 are not required to have a higher dimensional accuracy than the crimping portion 34, and thus are not formed with a higher dimensional accuracy than the crimping portion 34.
　端子圧着装置１は、連続端子３０に連ねられる端子３１（具体的には、端子３１の圧着部３４）に電線の端部を圧着固定する圧着機構２と、リール状に巻回された長尺の連続端子３０を繰り出して圧着機構２に送給する送給機構１０と、を含んでおり、圧着機構２と送給機構１０が連動して、送出経路（連続端子３０の長手方向）に沿って送出された端子３１を電線の端部に連続的に圧着する工程を行う構成となっている。 The terminal crimping device 1 includes a crimping mechanism 2 that crimps and fixes an end of an electric wire to a terminal 31 (specifically, a crimping portion 34 of the terminal 31) connected to a continuous terminal 30, and a long length wound in a reel shape. And the feeding mechanism 10 that feeds the continuous terminal 30 and feeds it to the crimping mechanism 2, and the crimping mechanism 2 and the feeding mechanism 10 work together along the delivery path (longitudinal direction of the continuous terminal 30). The terminal 31 sent out in this way is configured to perform a step of continuously crimping the terminal 31 to the end of the electric wire.
　圧着機構２は、連続端子３０に連ねられる複数の端子３１のうちの１つの端子３１を圧着金型（クリンパ５及びアンビル７）で加締めることによって、端子３１を電線に圧着する。圧着機構２は、具体的には、シャンクホルダ３内に昇降移動可能に収容されたシャンク４と、シャンク４の下端に配設されたクリンパ５（圧着用の上金型）と、クリンパ５に対向する位置に配設されたアンビル７（圧着用の下金型）とを主として備える。その他にも、圧着機構２には、連鎖帯３２から端子３１を裁断するためのカッタ（図示省略）等が含まれる。 The crimping mechanism 2 crimps the terminal 31 to the electric wire by crimping one terminal 31 of the plurality of terminals 31 connected to the continuous terminal 30 with a crimping die (the crimper 5 and the anvil 7). Specifically, the crimping mechanism 2 includes a shank 4 housed in the shank holder 3 so as to be movable up and down, a crimper 5 (an upper die for crimping) disposed at the lower end of the shank 4, and a crimper 5.

The connecting portion 22 is disposed above the uppermost position of the continuous terminal 30 (slightly above in the embodiment), and restricts the continuous terminal 30 from being displaced in the vertical direction.
　第１ガイド部２３は、端子３１の圧着部３４における軸心方向の一端側と当接させて、連続端子３０が前記軸心方向の一端側へ移動しないように規制すると共に、クリンパ５及びアンビル７の軸心上の位置（クリンパ５の真下）へ各端子３１の圧着部３４を案内するものである。 The first guide portion 23 is brought into contact with one end side in the axial direction of the crimping portion 34 of the terminal 31 to restrict the continuous terminal 30 from moving toward one end side in the axial direction, and the crimper 5 and the anvil. 7 to guide the crimping portion 34 of each terminal 31 to a position on the axis 7 (below the crimper 5).

The crimping portion 34 of each terminal 31 is guided to a position on the axial center (directly below the crimper 5).
　すなわち、第１ガイド部２３及び第２ガイド部２４は、圧着部３４におけるベルマウス量の精度を高めるために高い寸法精度に形成された圧着部３４における軸心方向の両端部を挟み込んで、ステージ１２上に送出される連続端子３０がステージ１２の幅方向に位置ずれしないように規制すると共に、クリンパ５及びアンビル７の軸心上の位置（クリンパ５の真下）へ各端子３１の圧着部３４を案内する。 That is, the first guide portion 23 and the second guide portion 24 sandwich the both end portions in the axial direction of the crimping portion 34 formed with high dimensional accuracy in order to increase the accuracy of the bell mouth amount in the crimping portion 34, and The continuous terminal 30 delivered onto the terminal 12 is regulated so as not to be displaced in the width direction of the stage 12, and the crimping portion 34 of each terminal 31 is moved to a position on the axial center of the crimper 5 and anvil 7 (below the crimper 5).

　第１ガイド部２３と第２ガイド部２４との間隔は、各端子３１の圧着部３４における軸心方向の寸法と略同じ寸法に形成されており、圧着部３４における軸心方向の両端部を、第１ガイド部２３と第２ガイド部２４とで前後方向から挟み込めるようになっている。 The distance between the first guide part 23 and the second guide part 24 is formed to be approximately the same as the dimension in the axial direction of the crimping part 34 of each terminal 31. The first guide portion 23 and the second guide portion 24 can be sandwiched from the front-rear direction.
　次に、ステージ１２に連続端子３０をセットする方法について説明する。各端子３１をステージ１２の一端側に向けると共に連鎖帯３２をステージ１２の他端側に向けた状態で、連続端子３０を送出経路の上流側からガイド部材２０の下側に通して、圧着部３４における軸心方向の両端部を第１ガイド部２３と第２ガイド部２４とで挟み込むようにして、連続端子３０をステージ１２にセットする。このように、第１ガイド部２３と第２ガイド部２４とで、圧着部３４における軸心方向の両端部が挟み込まれることにより、各端子３１の圧着部３４におけるベルマウス量を考慮した連続端子３０の位置決めがなされる。 Next, a method for setting the continuous terminal 30 on the stage 12 will be described. With each terminal 31 facing one end of the stage 12 and the chain band 32 facing the other end of the stage 12, the continuous terminal 30 is passed from the upstream side of the delivery path to the lower side of the guide member 20, The continuous terminal 30 is set on the stage 12 so that both end portions in the axial center direction of 34 are sandwiched between the first guide portion 23 and the second guide portion 24. Thus, the continuous terminal which considered the bell mouth amount in the crimping part 34 of each terminal 31 by pinching the both ends of the axial center direction in the crimping part 34 with the 1st guide part 23 and the 2nd guide part 24. 30 positionings are made.
　また、ガイド部材２０の連結部２２が弾性力を有する部材により形成されている場合は、ガイド部材２０の連結部２２の幅方向先端側を少し持ち上げて、連続端子３０をステージ１２上に載置してもよい。この場合、圧着部３４における軸心方向の両端部が第１ガイド部２３と第２ガイド部２４の真下になるように連続端子３０を動かしながら連結部２２の幅方向先端側を元の高さに下ろすことにより、第１ガイド部２３と第２ガイド部２４とで、圧着部３４における軸心方向の両端部が挟み込まれる。 Further, when the connecting portion 22 of the guide member 20 is formed of a member having elasticity, the continuous terminal 30 is placed on the stage 12 by slightly lifting the front end side in the width direction of the connecting portion 22 of the guide member 20. May be. In this case, while moving the continuous terminal 30 so that both end portions of the crimping portion 34 in the axial direction are directly below the first guide portion 23 and the second guide portion 24, the front end side in the width direction of the connecting portion 22 is the original height. The both ends of the crimping portion 34 in the axial direction are sandwiched between the first guide portion 23 and the second guide portion 24.
　なお、ガイド部材は、ステージ１２の側端部（連鎖体３２側）に連結されたガイド部材の連結部に配設されてもよい。また、第１ガイド部と第２ガイド部は別体であってもよい。この場合、第１ガイド部は、ステージ１２の側端部（圧着部３４側）に連結されたガイド部材の連結部に配設され、第２ガイド部は、ステージ１２の側端部（連鎖体３２側）に連結されたガイド部材の連結部に配設される。 Note that the guide member may be disposed in a connecting portion of the guide member connected to the side end portion (on the chain 32 side) of the stage 12. The first guide part and the second guide part may be separate. In this case, the first guide portion is disposed at the connecting portion of the guide member connected to the side end portion (crimping portion 34 side) of the stage 12, and the second guide portion is the side end portion (concatenated body) of the stage 12. 32 side) is provided at the connecting portion of the guide member.
　以上のように構成された端子圧着装置１によると、第１ガイド部２３を、寸法精度の高い芯線に対する圧着部３４における軸心方向の一端側と当接させると共に、第２ガイド部２４を、寸法精度の高い芯線に対する圧着部３４における軸心方向の他端側と当接させることにより、各端子３１の圧着部３４におけるベルマウス量を考慮した連続端子３０の位置決めを簡単に行うことができる。また、寸法精度の高い圧着部３４を第１ガイド部２３と第２ガイド部２４とで当接させるため、ロットを変更した場合にも、連続端子３０と第１ガイド部２３及び第２ガイド部２４との当接位置を調整することなく、前記ベルマウス量を考慮した連続端子３０の位置決めを簡単に行うことができる。 According to the terminal crimping apparatus 1 configured as described above, the first guide portion 23 is brought into contact with one end side in the axial direction of the crimp portion 34 with respect to the core wire with high dimensional accuracy, and the second guide portion 24 is By making contact with the other end side in the axial center direction of the crimping part 34 with respect to the core wire with high dimensional accuracy, the positioning of the continuous terminal 30 in consideration of the amount of the bell mouth in the crimping part 34 of each terminal 31 can be easily performed. . In addition, since the crimp part 34 with high dimensional accuracy is brought into contact with the first guide part 23 and the second guide part 24, the continuous terminal 30, the first guide part 23, and the second guide part can be used even when the lot is changed. The positioning of the continuous terminal 30 in consideration of the amount of the bell mouth can be easily performed without adjusting the contact position with 24.
　第１ガイド部２３と第２ガイド部２４とが連結部２２を介して一体的に形成されているため、１つの部材で、各端子３１の芯線に対する圧着部３４における軸心方向の一端側及び他端側を当接させることができ、第１ガイド部２３及び第２ガイド部２４の取付け誤差を低減できる。また、端子圧着装置１の構成を簡単にすることができる。 Since the first guide portion 23 and the second guide portion 24 are integrally formed via the connecting portion 22, one end side in the axial direction of the crimping portion 34 with respect to the core wire of each terminal 31 and one member, The other end side can be brought into contact with each other, and mounting errors of the first guide part 23 and the second guide part 24 can be reduced. Moreover, the structure of the terminal crimping apparatus 1 can be simplified.
　連結部２２は各端子３１の圧着部３４の上面と対向する位置に配設されているため、連結部２２により連続端子３０が鉛直方向に移動するのを規制することができる。 Since the connecting portion 22 is disposed at a position facing the upper surface of the crimping portion 34 of each terminal 31, the connecting portion 22 can restrict the continuous terminal 30 from moving in the vertical direction.
