本発明は、自動車の車両のボディ等のアース用部材に２箇所でボルト締めされて接地されるアース端子に関する。 The present invention relates to a ground terminal that is bolted to a grounding member such as a vehicle body of an automobile at two points to be grounded.

従来のアース端子では、１つの端子に１本のボルトにてアース用部材に締結固定する仕方が基本であったが、自動運転システム等の重要な回路の電源を保証するために、１つの端子に２本のボルトにてアース用部材に締結固定する仕方が普及している。この普及により、振動等に起因して１本のボルトに緩みが生じた場合でも端子外れという不具合が解消される。２箇所でボルト締めされるアース端子として、特許文献１及び特許文献２にそれぞれ記載されたものがある。 In the conventional ground terminal, the method of fastening and fixing to the grounding member with one bolt to one terminal was basic, but in order to guarantee the power supply of important circuits such as automatic operation systems, one terminal. The method of fastening and fixing to a grounding member with two bolts is widely used. With this widespread use, even if one bolt is loosened due to vibration or the like, the problem of terminal disconnection can be solved. As the ground terminal bolted at two places, there are those described in Patent Document 1 and Patent Document 2, respectively.

この特許文献１に記載されたアース端子は、第１のボルト挿通孔が開口された板状の端子本体部と、アース電線を接続する電線接続部と、を有している。板状の端子本体部は、端子軸方向に対して直交する方向に延設されていて、この延設部に第２のボルト挿通孔が開口されている。そして、板状の端子本体部は、第１と第２のボルト挿通孔に挿通される２本のボルトにてアース用部材の接地面に締結固定されるようになっている。 The ground terminal described in Patent Document 1 has a plate-shaped terminal main body portion in which a first bolt insertion hole is opened, and a wire connection portion for connecting a ground wire. The plate-shaped terminal body portion extends in a direction orthogonal to the terminal axial direction, and a second bolt insertion hole is opened in the extending portion. The plate-shaped terminal body is fastened and fixed to the grounding surface of the grounding member with two bolts inserted into the first and second bolt insertion holes.

また、特許文献２に記載されたアース端子は、端子軸方向に延びる矩形板状の端子本体部と、アース電線を接続する電線接続部と、を有している。この矩形板状の端子本体部には、その基端部（電線接続部）側と先端部側に２つのボルト挿通孔が開口されている。そして、矩形板状の端子本体部は、２つのボルト挿通孔に挿通される２本のボルトにてアース用部材の接地面に締結固定されるようになっている。 Further, the ground terminal described in Patent Document 2 has a rectangular plate-shaped terminal main body portion extending in the terminal axial direction and a wire connecting portion for connecting the ground wire. The rectangular plate-shaped terminal body has two bolt insertion holes on the base end (electric wire connection portion) side and the tip end side. The rectangular plate-shaped terminal body is fastened and fixed to the grounding surface of the grounding member with two bolts inserted into the two bolt insertion holes.

It is fastened and fixed to the ground contact surface 2 of the body 1 with 2 bolts 6.

以上実施形態のアース端子１０において、アース本体端子１１への第１締結プレート２０の組み付けは、先ず、図２に示すように、アース本体端子１１及び第１締結プレート２０を左右に並べ、次に、互いを近づけるように横にスライドさせる。この横のスライドにより、図３に示すように、アース本体端子１１の端子本体部１２の表面１２ａに第１締結プレート２０の重合平板部２１を重ね合わせる。この際、端子本体部１２の左右両側の被差込部１４，１５に重合平板部２１の左右両側の差込部２４，２５を差し込んで係止させ、かつ、端子本体部１２の係止孔１６に重合平板部２１の係止爪２６を係止させることで組み付けが完了する。その後、図４に示すように、アース本体端子１１の端子本体部１２と第１締結プレート２０の非重合平板部２２をボディ１の接地面２の所定位置に載置する。そして、重合平板部２１のボルト挿通孔２３と端子本体部１２のボルト挿通孔１３に第１ボルト５を挿通してナットを介して接地面２に締結固定し、かつ、非重合平板部２２のボルト挿通孔２７に第２ボルト６を挿通してナットを介して接地面２に締結固定する。よって、アース端子１０がボディ１に２箇所でボルト締めされて固定されているため、振動等に起因して１箇所のボルトに緩みが生じても、もう１箇所のボルトで固定されているため、アース端子１０がボディ１から外れることがなく、常に正確にアースが取れる。 In the ground terminal 10 of the above embodiment, in assembling the first fastening plate 20 to the ground main body terminal 11, first, as shown in FIG. 2, the ground main body terminal 11 and the first fastening plate 20 are arranged side by side, and then the first fastening plate 20 is arranged side by side. , Slide sideways to bring them closer together. By this horizontal slide, as shown in FIG. 3, the polymerized flat plate portion 21 of the first fastening plate 20 is superposed on the surface 12a of the terminal main body portion 12 of the ground main body terminal 11. At this time, the insertion portions 24, 25 on the left and right sides of the polymerized flat plate portion 21 are inserted into the insertion portions 14, 15 on the left and right sides of the terminal body portion 12 to be locked, and the locking holes of the terminal body portion 12 are locked. Assembly is completed by locking the locking claw 26 of the polymerized flat plate portion 21 to 16. After that, as shown in FIG. 4, the terminal main body portion 12 of the ground main body terminal 11 and the non-polymerized flat plate portion 22 of the first fastening plate 20 are placed at predetermined positions on the grounding surface 2 of the body 1. Then, the first bolt 5 is inserted into the bolt insertion hole 23 of the polymerized flat plate portion 21 and the bolt insertion hole 13 of the terminal main body 12, and fastened and fixed to the ground plane 2 via a nut, and the non-polymerized flat plate portion 22. The second bolt 6 is inserted into the bolt insertion hole 27 and fastened and fixed to the ground plane 2 via a nut. Therefore, since the ground terminal 10 is bolted to the body 1 at two points and fixed to the body 1, even if one bolt is loosened due to vibration or the like, it is fixed to the body 1 with another bolt. , The ground terminal 10 does not come off from the body 1, and the ground can always be taken accurately.

また、ボディ１の形状等によりアース端子１０の搭載形態が異なる場合には、その搭載形態に合わせた形状に予め作製しておいた第２締結プレート３０を用いる。アース本体端子１１への第２締結プレート３０の組み付けは、先ず、図５に示すように、アース本体端子１１及び第２締結プレート３０を左右に並べ、次に、互いを近づけるように横にスライドさせる。この横のスライドにより、図６に示すように、アース本体端子１１の端子本体部１２の表面１２ａに第２締結プレート３０の重合平板部３１を重ね合わせる。この際、端子本体部１２の左右両側の被差込部１４，１５に重合平板部３１の左右両側の差込部３４，３５を差し込んで係止させ、かつ、端子本体部１２の係止孔１６に重合平板部３１の係止爪３６を係止させることで組み付けが完了する。その後、図７に示すように、アース本体端子１１の端子本体部１２と第２締結プレート３０の非重合平板部３２をボディ１の接地面２の所定位置に載置する。そして、重合平板部３１のボルト挿通孔３３と端子本体部１２のボルト挿通孔１３に第１ボルト５を挿通してナットを介して接地面２に締結固定し、かつ、非重合平板部３２のボルト挿通孔３７に第２ボルト６を挿通してナットを介して接地面２に締結固定する。よって、アース端子１０がボディ１に２箇所でボルト締めされて固定されているため、振動等に起因して１箇所のボルトに緩みが生じても、もう１箇所のボルトで固定されているため、アース端子１０がボディ１から外れることがなく、常に正確にアースが取れる。 When the mounting form of the ground terminal 10 differs depending on the shape of the body 1 or the like, the second fastening plate 30 prepared in advance in a shape matching the mounting form is used. To assemble the second fastening plate 30 to the ground main body terminal 11, first, as shown in FIG. 5, the ground main body terminal 11 and the second fastening plate 30 are arranged side by side, and then slide sideways so as to bring them closer to each other. Let me. By this horizontal slide, as shown in FIG. 6, the polymerized flat plate portion 31 of the second fastening plate 30 is superposed on the surface 12a of the terminal main body portion 12 of the ground main body terminal 11. At this time, the insertion portions 34, 35 on the left and right sides of the polymerized flat plate portion 31 are inserted into the insertion portions 14, 15 on the left and right sides of the terminal body portion 12 to be locked, and the locking holes of the terminal body portion 12 are locked. Assembly is completed by locking the locking claw 36 of the polymerized flat plate portion 31 to 16. After that, as shown in FIG. 7, the terminal main body portion 12 of the ground main body terminal 11 and the non-polymerized flat plate portion 32 of the second fastening plate 30 are placed at predetermined positions on the grounding surface 2 of the body 1. Then, the first bolt 5 is inserted into the bolt insertion hole 33 of the polymerized flat plate portion 31 and the bolt insertion hole 13 of the terminal main body 12, and fastened and fixed to the ground plane 2 via a nut, and the non-polymerized flat plate portion 32. The second bolt 6 is inserted into the bolt insertion hole 37 and fastened and fixed to the ground plane 2 via a nut. Therefore, since the ground terminal 10 is bolted to the body 1 at two points and fixed to the body 1, even if one bolt is loosened due to vibration or the like, it is fixed to the body 1 with another bolt. , The ground terminal 10 does not come off from the body 1, and the ground can always be taken accurately.

このように、ボディ１の形状に合わせて、アース本体端子１１に組み付けられる第１締結プレート２０か第２締結プレート３０の２つの締結プレートを用意しておくことで対応することができる。このため、各締結プレート２０，３０は、バリエーションを予め作製しておくことで、金型費用の低減や開発工数の削減を図ることができ、自由度のある設計が可能となる。これにより、ボディ１の形状に合わせて、アース本体端子１１に第１締結プレート２０か第２締結プレート３０の何方かを組み付けてアース端子１０とすることができるため、ボディ１の接地面２に２箇所のボルト締めにより低コストで簡単かつ確実にアース端子１０を組み付けることができる。 As described above, it is possible to cope with this by preparing two fastening plates, the first fastening plate 20 and the second fastening plate 30, which are assembled to the ground main body terminal 11 according to the shape of the body 1. Therefore, by preparing variations of the fastening plates 20 and 30 in advance, it is possible to reduce the mold cost and the development man-hours, and it is possible to design with a degree of freedom. As a result, either the first fastening plate 20 or the second fastening plate 30 can be assembled to the grounding body terminal 11 to form the grounding terminal 10 according to the shape of the body 1, so that the grounding surface 2 of the body 1 can be formed. The ground terminal 10 can be easily and reliably assembled at low cost by tightening two bolts.
