Description

本発明は、導通検査治具に使用される導通ピンの先端径を判別するピン径判別治具及びピン径判別方法に関する。   The present invention relates to a pin diameter discriminating jig and a pin diameter discriminating method for discriminating a tip diameter of a conducting pin used in a continuity inspection jig.

車両内に配索されて各種電子機器等の接続に用いられるワイヤハーネスは、コネクタハウジングに収容される端子が端末に設けられた複数の電線を有している。そして、このようなワイヤハーネスに対して、電線の断線や端子の接続不良等を検出するための導通検査が行われる。   A wire harness that is routed in a vehicle and used for connecting various electronic devices and the like has a plurality of electric wires in which terminals accommodated in a connector housing are provided at a terminal. Then, a continuity test is performed on such a wire harness in order to detect disconnection of the electric wire, poor connection of the terminal, and the like.

導通検査は、複数の電線の端末に接続された端子の数の複数の導通ピンを有した導通検査治具を用い、この導通検査治具の各導通ピンを雌コネクタハウジングの複数の端子収容室内に収容されている各雌端子と接触させることで行っている。   The continuity test uses a continuity test jig having a plurality of continuity pins connected to the terminals of the plurality of electric wires, and each continuity pin of the continuity test jig is placed in a plurality of terminal accommodating chambers of the female connector housing. This is done by contacting each female terminal housed in the housing.

前記導通検査治具の複数の導通ピンによる導通検査の際に、雌端子の大きさに合った先端径の導通ピンを使用しなければ端子変形の原因となるため、適正な先端径の導通ピンが使用されている導通検査治具であるかどうか、即ち、導通検査治具が適正品か否かのチェックをする必要があるが、導通ピンの先端径を判別する具体的な手段や手法はなく、例えば、ノギス等の測定機器や筒状の部品を代用して対応していた。   When conducting a continuity test using a plurality of continuity pins of the continuity inspection jig, if a continuity pin having a tip diameter matching the size of the female terminal is not used, the terminal will be deformed. It is necessary to check whether or not the continuity inspection jig is used, that is, whether or not the continuity inspection jig is an appropriate product. For example, measuring devices such as calipers and cylindrical parts are used instead.

しかしながら、未完成状態の導通検査治具に組み付けた導通ピンをノギス等の測定機器で１本毎測定しようとしても、複数の導通ピン間のピッチが小さくて測定が困難であり、また、筒状の部品で測定するために導通ピンの先端に押し込もうとした場合、誤って導通ピンを変形させたり、破損させる恐れがあり、適正品であるか否かの判別に時間と熟練を要した。   However, even if it is attempted to measure each of the conductive pins assembled to the unfinished conductive inspection jig with a measuring device such as a caliper, the pitch between the plurality of conductive pins is small, and measurement is difficult. If you try to push it into the tip of the conducting pin to measure with the parts of this, there is a risk of accidentally deforming or damaging the conducting pin, and it took time and skill to determine whether it is a proper product .

そこで、本発明は、前記した課題を解決すべくなされたものであり、導通検査治具の導通ピンのピン径を簡単かつ短時間で正確に判別することができるピン径判別治具及びピン径判別方法を提供することを目的とする。詳述すると、導通検査治具に使用する導通ピンが誤って、異なる先端径の導通ピンが取り付けられた際（製造時、受入時、メンテナンス時等）に、ピン径の違いを容易に確認させることで、導通検査治具のピン径違い品を流出させないことを目的とする。   Therefore, the present invention has been made to solve the above-described problems, and a pin diameter determination jig and a pin diameter that can easily and accurately determine the pin diameter of the conduction pin of the conduction inspection jig. An object is to provide a discrimination method. In detail, when the conducting pin used for the continuity inspection jig is mistaken and a conducting pin with a different tip diameter is attached (manufacturing, receiving, maintenance, etc.), the difference in pin diameter can be easily confirmed. Thus, the object is to prevent the continuity inspection jig from having different pin diameters.

本発明は、導通検査治具の導通ピンのピン径を判別するピン径判別治具であって、導通検査治具の導通ピンのピン径を判別するコイルバネと、前記コイルバネを一体に結合した把持部と、を備えたことを特徴とする。   The present invention is a pin diameter discriminating jig for discriminating a pin diameter of a conducting pin of a continuity testing jig, and a gripping unit that integrally couples a coil spring that discriminates the pin diameter of a conducting pin of a continuity testing jig. And a section.

また、本発明は、ピン径判別治具を用いて導通検査治具の導通ピンのピン径を判別するピン径判別方法であって、前記導通ピンの外径をφＰ、前記ピン径判別治具の把持部の一方の側の大径のコイルバネの内径をφＡ、前記把持部の他方の側の小径のコイルバネの内径をφＢとした場合に、前記導通ピンの外径φＰと前記大径のコイルバネの内径φＡと前記小径のコイルバネの内径φＢの関係がφＡ≧φＰ＞φＢの場合は、前記導通ピンが適正品であると判別し、φＡ＞φＰ＜φＢ及びφＡ＜φＰ＞φＢの場合は、前記導通ピンが不適正品であると判別することを特徴とする。   The present invention is also a pin diameter determining method for determining a pin diameter of a conducting pin of a continuity inspection jig using a pin diameter determining jig, wherein the outer diameter of the conducting pin is φP, and the pin diameter determining jig When the inner diameter of the large-diameter coil spring on one side of the grip portion is φA and the inner diameter of the small-diameter coil spring on the other side of the grip portion is φB, the outer diameter φP of the conducting pin and the large-diameter coil spring When the relationship between the inner diameter φA of the coil spring and the inner diameter φB of the small-diameter coil spring is φA ≧ φP> φB, it is determined that the conductive pin is an appropriate product. It is determined that the conductive pin is an inappropriate product.

本発明によれば、導通検査治具の導通ピンのピン径を簡単かつ短時間で正確に判別することができる。   According to the present invention, the pin diameter of the conduction pin of the conduction inspection jig can be easily and accurately determined in a short time.

It is a side view of a discrimination jig.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は本発明の第１実施形態のピン径判別治具の側面図、図２は同ピン径判別治具の一方の側の大径のコイルバネに導通ピンを挿入した状態を一部断面で示す要部拡大図、図３は同ピン径判別治具の他方の側の小径のコイルバネに導通ピンを挿入した状態を一部断面で示す要部拡大図である。   FIG. 1 is a side view of a pin diameter discriminating jig according to a first embodiment of the present invention, and FIG. 2 is a partial cross-sectional view showing a state where a conducting pin is inserted into a large-diameter coil spring on one side of the pin diameter discriminating jig. FIG. 3 is an enlarged view of a main part, partially showing a state where a conducting pin is inserted into a small-diameter coil spring on the other side of the pin diameter determining jig.

図１に示すように、ピン径判別治具１は、導通検査治具（図示省略）に設計段階で選定された導通ピン１０が正規の状態で組み付けられているかどうかを容易に判別できる治具であり、導通ピン１０の先端径（ピン径）を判別する長尺で金属製の一対のねじりコイルバネ（コイルバネ）３，４と、この一対のねじりコイルバネ（コイルバネ）３，４を一体に結合した合成樹脂製で四角棒状の把持部２と、を備えている。   As shown in FIG. 1, the pin diameter discriminating jig 1 is a jig that can easily discriminate whether or not the conducting pin 10 selected in the design stage is assembled in a normal state to a conducting inspection jig (not shown). The pair of long and metal torsion coil springs (coil springs) 3 and 4 for determining the tip diameter (pin diameter) of the conductive pin 10 and the pair of torsion coil springs (coil springs) 3 and 4 are integrally coupled. And a square bar-shaped grip 2 made of synthetic resin.

把持部２は、左右両側にそれぞれ径の異なるねじりコイルバネ３，４を一体に結合してあり、かつ把持部２の左右両側は、その外径を異なるねじりコイルバネ３，４の径に合わせてそれぞれ異ならせて形成してある。即ち、把持部２の一方の側（図１中左のＡ側）は大径部２ａになっており、把持部２の他方の側（図１中右のＢ側）は小径部２ｂになっている。このように、２つの導通ピン１０の先端径の判別部である各ねじりコイルバネ３，４を容易に判別でき、かつ取り間違い防止のため、把持部２と各ねじりコイルバネ３，４は一体構造で、判別部である各ねじりコイルバネ３，４の大小に応じてその取付外形に段差を設けている。   The grip portion 2 is integrally coupled with torsion coil springs 3 and 4 having different diameters on the left and right sides, and the left and right sides of the grip portion 2 are respectively adjusted to have different outer diameters corresponding to the diameters of the torsion coil springs 3 and 4. They are formed differently. That is, one side (left side A in FIG. 1) of the grip portion 2 is a large diameter portion 2a, and the other side (right side B in FIG. 1) is a small diameter portion 2b. ing. In this way, the torsion coil springs 3 and 4 that are the tip diameter discriminating portions of the two conducting pins 10 can be easily discriminated and the gripping portion 2 and the torsion coil springs 3 and 4 have an integral structure to prevent mistakes. In accordance with the size of each of the torsion coil springs 3 and 4 which are the discriminating portions, a step is provided in the mounting outer shape.

また、一方の側（図１中左のＡ側）のねじりコイルバネ３は他方の側（図１中右のＢ側）のねじりコイルバネ４よりも大径に形成されている。さらに、各ねじりコイルバネ３，４の先端部には導通ピン１０を挿入し易くするために螺旋状に外側に拡径するテーパ部３ａ，４ａを形成してある。尚、各ねじりコイルバネ３，４は、金属製の棒を密着巻きしてねじりコイル状に形成してあり、ピッチ間が狭い複数の導通ピン１０を判別する場合でも隣接する各導通ピン１０にダメージを与えないようにフレキシブルに弾性変形するようになっている。   Further, the torsion coil spring 3 on one side (left side A in FIG. 1) is formed to have a larger diameter than the torsion coil spring 4 on the other side (right side B in FIG. 1). Further, tapered portions 3a and 4a are formed at the distal end portions of the torsion coil springs 3 and 4 so that the diameter of the conductive pin 10 is increased outward in a spiral manner so that the conducting pin 10 can be easily inserted. The torsion coil springs 3 and 4 are formed in a torsion coil shape by tightly winding a metal rod, and even when a plurality of conduction pins 10 having a narrow pitch are discriminated, the adjacent conduction pins 10 are damaged. It is designed to be elastically deformed flexibly so as not to give it.

そして、サイズ違い（大）の導通ピン１０を判別する方法として、選定された導通ピン１０の先端部１０ａが入り、且つ１サイズ先端径の大きな導通ピン１０が入らないようにねじりコイルバネ３，４の内径を設定する。また、サイズ違い（小）の導通ピン１０を判別する方法として、選定された導通ピン１０の先端部１０ａが入らず、且つ１サイズ先端径の小さな導通ピン１０が入るようにねじりコイルバネ３，４の内径を設定する。即ち、選定（判別）する導通ピン１０の外径をφＰ、把持部２の一方の側（図１中左のＡ側）の大径のコイルバネ３の内径をφＡ、把持部２の他方の側（図１中右のＢ側）の小径のコイルバネ４の内径をφＢとした場合に、φＡ≧φＰ＞φＢの関係となっている。   As a method of discriminating the conductive pins 10 of different sizes (large), the torsion coil springs 3 and 4 are inserted so that the leading end portion 10a of the selected conducting pin 10 is inserted and the conducting pin 10 having a large one-end tip diameter is not inserted. Set the inner diameter of. Further, as a method of discriminating the conductive pins 10 of different sizes (small), the torsion coil springs 3 and 4 are arranged so that the leading end portion 10a of the selected conductive pin 10 does not enter and the conductive pin 10 having a small one-size tip diameter enters. Set the inner diameter of. That is, the outer diameter of the conducting pin 10 to be selected (discriminated) is φP, the inner diameter of the large-diameter coil spring 3 on one side (left side A in FIG. 1) of the holding portion 2 is φA, and the other side of the holding portion 2 When the inner diameter of the small coil spring 4 on the right side (B side in FIG. 1) is φB, the relationship is φA ≧ φP> φB.

詳述すると、前述した構成のピン径判別治具１を用いて導通検査治具の導通ピン１０の先端径（ピン径）を判別する際に、選定する導通ピン１０の外径をφＰ、把持部２のＡ側の大径のばね３の内径をφＡ、把持部２のＢ側の小径のばね４の内径をφＢとした場合に、それらの関係がφＡ≧φＰ＞φＢの場合は、選定された導通ピン１０が適正品（ＯＫ）であると判別し、φＡ＞φＰ＜φＢ及びφＡ＜φＰ＞φＢの場合は、選定された導通ピン１０が不適正品（ＮＧ）であると判別する。   More specifically, when the tip diameter (pin diameter) of the conduction pin 10 of the conduction inspection jig is determined using the pin diameter determination jig 1 having the above-described configuration, the outer diameter of the selected conduction pin 10 is φP. When the inner diameter of the large-diameter spring 3 on the A side of the part 2 is φA and the inner diameter of the small-diameter spring 4 on the B side of the gripping part 2 is φB, if the relationship is φA ≧ φP> φB, select It is determined that the selected conduction pin 10 is an appropriate product (OK). If φA> φP <φB and φA <φP> φB, it is determined that the selected conduction pin 10 is an inappropriate product (NG).

即ち、判別(確認)手順としては、図４に示すように、導通ピン１０がＡ側のコイルバネ３に挿入され（Ｇｏ）、Ｂ側のコイルバネ４にも挿入された（Ｇｏ）場合、及び、導通ピン１０がＡ側のコイルバネ３に挿入されず（ＮｏＧｏ）、Ｂ側のコイルバネ４にも挿入されない（ＮｏＧｏ）場合は、正規（適正品）の先端径の導通ピン１０が組み付けられていないことが確認される。   That is, as a discrimination (confirmation) procedure, as shown in FIG. 4, when the conduction pin 10 is inserted into the A side coil spring 3 (Go) and also inserted into the B side coil spring 4 (Go), and If the conduction pin 10 is not inserted into the A-side coil spring 3 (NoGo) and not inserted into the B-side coil spring 4 (NoGo), the regular (proper product) tip pin 10 is not assembled. Is confirmed.

また、導通ピン１０がＡ側のコイルバネ３に挿入され（Ｇｏ）、Ｂ側のコイルバネ４に挿入されない（ＮｏＧｏ）場合は、正規（適正品）の先端径の導通ピン１０が組み付けられていることが確認される。これらにより、導通ピン１０が適正品（ＯＫ）か不適正品（ＮＧ）かが簡単に判る。   In addition, when the conduction pin 10 is inserted into the A-side coil spring 3 (Go) and not inserted into the B-side coil spring 4 (NoGo), the conduction pin 10 having a regular (proper product) tip diameter is assembled. Is confirmed. Thus, it can be easily understood whether the conduction pin 10 is an appropriate product (OK) or an inappropriate product (NG).

このように、ピン径判別治具１を用いて、選定する導通ピン１０を、各テーパ部３ａ，４ａを介してコイルバネ３，４内に挿入させることができるか、挿入させることができないかを確認するだけの簡単な手作業により、導通ピン１０の先端径（ピン径）を短時間で正確に判別することができる。   Thus, using the pin diameter discriminating jig 1, it is determined whether or not the conduction pin 10 to be selected can be inserted into the coil springs 3 and 4 via the taper portions 3a and 4a. The tip diameter (pin diameter) of the conductive pin 10 can be accurately determined in a short time by a simple manual operation that only requires confirmation.

導通検査治具に組み付けられた状態の導通ピン１０の先端径を確認することで、完成品の検査時、製造業者からの治具受入時、メンテナンス等によるピン交換時に、ピン径が異なる導通ピン１０を備えた導通検査治具の流出を確実に防止することができる。さらに、検査、受入・メンテナンス時の確認工数の削減を図ることができ、その分、低コスト化を図ることができる。   Conductive pins with different pin diameters when inspecting the finished product, receiving a jig from the manufacturer, or exchanging pins for maintenance, etc. The outflow of the continuity inspection jig provided with 10 can be reliably prevented. Furthermore, it is possible to reduce the number of confirmation steps at the time of inspection, acceptance / maintenance, and the cost can be reduced accordingly.

また、選定された導通ピン１０のピン径を判別する際に、フレキシブルに弾性変形する長尺のねじりコイルバネ３，４を用いたことにより、導通ピン１０の変形や破損等の２次的な不具合を回避することができる。   Further, when determining the pin diameter of the selected conduction pin 10, secondary troubles such as deformation or breakage of the conduction pin 10 are obtained by using the long torsion coil springs 3 and 4 that are elastically deformed flexibly. Can be avoided.

図５（ａ）は本発明の第２実施形態のピン径判別治具のコイルバネを他のピン径に対応したものに取り換えるための組み合わせを示す側面図、図５（ｂ）は同組み合わせた一例を示すピン径判別治具の側面図である。   FIG. 5A is a side view showing a combination for replacing the coil spring of the pin diameter determination jig of the second embodiment of the present invention with one corresponding to another pin diameter, and FIG. 5B is an example of the combination. It is a side view of the pin diameter discrimination | determination jig | tool which shows these.

The hole 2c and the small-diameter divided body 2B are detachable by screwing of a screw portion 2d formed on one end side. In addition, you may make it detachable with a magnet instead of a screw.

また、図５（ａ）に示すように、大径分割体２Ａの一端側には、大径のうちでも径の異なる大径のコイルバネ３，３′，３″を一体に結合したものが３組み用意されている。さらに、図５（ｂ）に示すように、小径分割体２Ｂの他端側には、小径のうちでも径の異なる小径のコイルバネ４，４′，４″を一体に結合したものが３組み用意されている。これらの各分割体Ａ２，２Ｂを、選定する導通ピン１０の他のピン径、即ち、ピン径の大小異なる導通ピン１０に合わせて対応したものに取り換えて使用することにより、先端径のそれぞれ異なる複数種類の導通ピン１０の判別に簡単かつ確実に対応させて判別することができる。   Further, as shown in FIG. 5 (a), a large-diameter divided body 2A is integrally joined with large-diameter coil springs 3, 3 ′, 3 ″ having different diameters on one end side. Further, as shown in Fig. 5 (b), small-diameter coil springs 4, 4 ', 4 "having different diameters are integrally coupled to the other end of the small-diameter divided body 2B. Three sets are prepared. By using each of these divided bodies A2 and 2B by replacing them with other pin diameters of the conducting pins 10 to be selected, that is, corresponding to the conducting pins 10 having different pin diameters, the tip diameters are different. The determination can be made in a simple and reliable manner corresponding to the determination of the plurality of types of conductive pins 10.

尚、前記各実施形態によれば、導通ピンのピン径を判別するコイルバネを金属製の棒を密着巻きしてねじりコイル状に形成したものを用いたが、合成樹脂製のねじりコイルバネを用いても良い。   In addition, according to each said embodiment, although the coil spring which discriminate | determines the pin diameter of a conduction | electrical_connection pin used what formed the torsion coil shape by tightly winding metal rods, it uses a synthetic resin torsion coil spring.
