上記バスバ保持構造１において、第１上ガイド部３２０ｂ、３２０ｃは、第１挿入口３２ｍから第１貫通口３２ｐに向けて挿入方向に沿って挿入される第１バスバ２１の第２接点部２１ｂを第１支持面３２ｓとの間で挟み、且つ、第１接点部２１ａが第１貫通口３２ｐに貫通した状態で第２接点部２１ｂを第１支持面３２ｓとの間で挟む。同様に、第２上ガイド部３２０ｆ、３２０ｇは、第２挿入口３２ｎから第２貫通口３２ｑに向けて挿入方向に沿って挿入される第２バスバ２２の第２接点部２２ｂを第２支持面３２ｔとの間で挟み、且つ、第１接点部２２ａが第２貫通口３２ｑに貫通した状態で第２接点部２２ｂを第２支持面３２ｔとの間で挟む。 In the bus bar holding structure 1, the first upper guide portions 320b and 320c have a second contact portion 21b of the first bus bar 21 inserted along the insertion direction from the first insertion port 32m toward the first through port 32p. The second contact portion 21b is sandwiched between the first support surface 32s and the first support surface 32s in a state where the first contact portion 21a penetrates the first through port 32p. Similarly, the second upper guide portions 320f and 320g support the second contact portion 22b of the second bus bar 22 inserted along the insertion direction from the second insertion port 32n toward the second through port 32q. The second contact portion 22b is sandwiched between the second support surface 32t and the second contact portion 22a in a state where the first contact portion 22a penetrates the second through port 32q.

この構成により、バスバ保持構造１は、第１挿入口３２ｍから第１貫通口３２ｐに向けて第１バスバ２１を挿入するときに案内することができ、且つ、第１接点部２１ａが第１貫通口３２ｐに貫通した状態で第１バスバ２１を規定の位置に定めることができる。また、バスバ保持構造１は、第１バスバ２１と同様に第２バスバ２２を挿入時に案内できると共に挿入後に規定の位置に定めることができる。 With this configuration, the bus bar holding structure 1 can be guided when the first bus bar 21 is inserted from the first insertion port 32m toward the first through port 32p, and the first contact portion 21a is the first penetration. The first bus bar 21 can be set at a specified position while penetrating the mouth 32p. Further, the bus bar holding structure 1 can guide the second bus bar 22 at the time of insertion and can be set at a predetermined position after the insertion, similarly to the first bus bar 21.

上記バスバ保持構造１は、幅方向において互いに対向し第１バスバ２１の第２接点部２１ｂの幅方向の両側を幅方向から挟む一対の第１横ガイド部３２０ｄ、３２０ｅを有する。また、バスバ保持構造１は、幅方向において互いに対向し第２バスバ２２の第２接点部２２ｂの幅方向の両側を幅方向から挟む一対の第２横ガイド部３２０ｈ、３２０ｉを有する。この構成により、バスバ保持構造１は、一対の第１横ガイド部３２０ｄ、３２０ｅにより第１バスバ２１の幅方向の位置を規制することができ、一対の第２横ガイド部３２０ｈ、３２０ｉにより第２バスバ２２の幅方向の位置を規制することができる。 The bus bar holding structure 1 has a pair of first lateral guide portions 320d and 320e that face each other in the width direction and sandwich both sides of the second contact portion 21b of the first bus bar 21 in the width direction from the width direction. Further, the bus bar holding structure 1 has a pair of second lateral guide portions 320h and 320i that face each other in the width direction and sandwich both sides of the second contact portion 22b of the second bus bar 22 in the width direction from the width direction. With this configuration, the bus bar holding structure 1 can regulate the position of the first bus bar 21 in the width direction by the pair of first horizontal guide portions 320d and 320e, and the second by the pair of second horizontal guide portions 320h and 320i. The position of the bus bar 22 in the width direction can be regulated.

上記バスバ保持構造１において、第１バスバ２１は、第１ボルト５１が挿入される第１孔部２１ｃを第２接点部２１ｂに有する。筐体３０は、第１支持面３２ｓよりも窪んで形成され、第１接点部２１ａが第１貫通口３２ｐに貫通した状態において第１バスバ２１の第１孔部２１ｃと厚み方向に対向し、第１ナット４１を格納する第１凹部３２ｗを有する。第１バスバ２１は、第２孔部１４を有するヒューズ端子１１の第２孔部１４と当該第１バスバ２１の第１孔部２１ｃとが位置合わせされた状態で、厚み方向の第１凹部３２ｗとは反対側から第２孔部１４及び第１孔部２１ｃに挿入された第１ボルト５１が、第１凹部３２ｗに格納された第１ナット４１に締結されている。同様に、第２バスバ２２は、第２孔部１５を有するヒューズ端子１２の第２孔部１５と当該第２バスバ２２の第１孔部２２ｃとが位置合わせされた状態で、厚み方向の第２凹部３２ｘとは反対側から第２孔部１５及び第１孔部２２ｃに挿入された第２ボルト５２が、第２凹部３２ｘに格納された第２ナット４２に締結されている。この構成により、バスバ保持構造１は、例えば、第１ボルト５１と第１ナット４１を締結するとき、第１上ガイド部３２０ｂ、３２０ｃにより第１バスバ２１の位置が規制されているので、第１ナット４１に傾きが生じても第１バスバ２１のアライメントに影響がでることを抑制できる。同様に、バスバ保持構造１は、第２上ガイド部３２０ｆ、３２０ｇにより、第２ナット４２に傾きが生じても第２バスバ２２のアライメントに影響がでることを抑制できる。 In the bus bar holding structure 1, the first bus bar 21 has a first hole portion 21c into which the first bolt 51 is inserted in the second contact portion 21b. The housing 30 is formed so as to be recessed from the first support surface 32s, and faces the first hole portion 21c of the first bus bar 21 in the thickness direction in a state where the first contact portion 21a penetrates the first through port 32p. It has a first recess 32w for accommodating the first nut 41. The first bus bar 21 has a first recess 32w in the thickness direction in a state where the second hole 14 of the fuse terminal 11 having the second hole 14 and the first hole 21c of the first bus bar 21 are aligned. The first bolt 51 inserted into the second hole portion 14 and the first hole portion 21c from the opposite side is fastened to the first nut 41 stored in the first recess 32w. Similarly, in the second bus bar 22, the second hole portion 15 of the fuse terminal 12 having the second hole portion 15 and the first hole portion 22c of the second bus bar 22 are aligned with each other in the thickness direction. The second bolt 52 inserted into the second hole portion 15 and the first hole portion 22c from the side opposite to the second recess 32x is fastened to the second nut 42 housed in the second recess 32x. With this configuration, in the bus bar holding structure 1, for example, when the first bolt 51 and the first nut 41 are fastened, the position of the first bus bar 21 is restricted by the first upper guide portions 320b and 320c, so that the first bus bar holding structure 1 is first. Even if the nut 41 is tilted, it is possible to prevent the alignment of the first bus bar 21 from being affected. Similarly, in the bus bar holding structure 1, the second upper guide portions 320f and 320 g can prevent the alignment of the second bus bar 22 from being affected even if the second nut 42 is tilted.

上記バスバ保持構造１において、第１ナット４１は、第１ボルト５１に締結される前の状態において、第１ナット４１の厚み方向の第１バスバ２１側の端部が第１支持面３２ｓよりも第１凹部３２ｗの底面側に位置する。同様に、第２ナット４２は、第２ボルト５２に締結される前の状態において、第２ナット４２の厚み方向の第２バスバ２２側の端部が第２支持面３２ｔよりも第２凹部３２ｘの底面側に位置する。この構成により、バスバ保持構造１は、第１バスバ２１を第１挿入口３２ｍから第１貫通口３２ｐに向けて挿入する場合、第１バスバ２１の第１接点部２１ａが第１ナット４１に接触又は追突することを抑制することができる。この抑制により、バスバ保持構造１は、第１接点部２１ａが損傷することを抑制することができ、第１バスバ２１の品質を維持することができる。また、バスバ保持構造１は、第２バスバ２２についても同様に、第１接点部２２ａが第２ナット４２に接触又は追突することを抑制することができる。 In the bus bar holding structure 1, the end of the first nut 41 on the first bus bar 21 side in the thickness direction of the first nut 41 is larger than the first support surface 32s in the state before being fastened to the first bolt 51. It is located on the bottom surface side of the first recess 32w. Similarly, in the state before the second nut 42 is fastened to the second bolt 52, the end portion of the second nut 42 on the second bus bar 22 side in the thickness direction is the second recess 32x with respect to the second support surface 32t. Located on the bottom side of. With this configuration, in the bus bar holding structure 1, when the first bus bar 21 is inserted from the first insertion port 32m toward the first through port 32p, the first contact portion 21a of the first bus bar 21 contacts the first nut 41. Alternatively, it is possible to suppress a rear-end collision. By this suppression, the bus bar holding structure 1 can prevent the first contact portion 21a from being damaged, and can maintain the quality of the first bus bar 21. Further, the bus bar holding structure 1 can similarly prevent the first contact portion 22a from coming into contact with or colliding with the second nut 42 for the second bus bar 22.
