従来より、自動車用の電気接続箱には、配線部材としてバスバが用いられている。また、図７は従来のバスバを示す斜視図である。図８は従来の他のバスバを示す斜視図である（特許文献１を参照。）。   Conventionally, bus bars are used as wiring members in electrical junction boxes for automobiles. FIG. 7 is a perspective view showing a conventional bus bar. FIG. 8 is a perspective view showing another conventional bus bar (see Patent Document 1).

図７に示すバスバ２０１は、１枚の金属板にプレス加工が施されて得られるものであり、基部２２０と、リレー等と電気接続される複数の端子２２１と、ヒューズと電気接続される複数の音叉状端子２３１と、を有している。   The bus bar 201 shown in FIG. 7 is obtained by pressing a single metal plate, and includes a base 220, a plurality of terminals 221 electrically connected to a relay and the like, and a plurality of terminals electrically connected to a fuse. And a tuning fork terminal 231.

上記音叉状端子２３１は、ヒューズの端子が圧入される溝２３２が形成された音叉状に形成されている。また、この音叉状端子２３１が溝２３２にヒューズの端子を確実に挟持するためには、バスバ２０１の材料自体が持っているバネ性が重要であることから、バスバ２０１に使用できる材料は限定されており、そのため安価な材料を使用することができなかった。   The tuning fork terminal 231 is formed in a tuning fork shape in which a groove 232 into which a fuse terminal is press-fitted is formed. In addition, in order for the tuning fork terminal 231 to securely hold the fuse terminal in the groove 232, the spring property of the material of the bus bar 201 itself is important, so the materials that can be used for the bus bar 201 are limited. Therefore, inexpensive materials could not be used.

また、別体部３Ａには、前述した板部３０の前記一つの外縁３０ａと対向する外縁３０ｂ、即ち別体部３Ａの外縁３０ｂ、から凹に形成された凹部５が３つ設けられている。これら凹部５は、前記凸部４と等しい形状でかつ凸部４よりもわずかに小さく形成されている。また、図４中の点線は、凹部５に対する凸部４の大きさを表している。   In addition, the separate part 3A is provided with three recesses 5 formed as a recess from the outer edge 30b of the plate part 30 facing the one outer edge 30a, that is, the outer edge 30b of the separate part 3A. . These concave portions 5 have the same shape as the convex portions 4 and are slightly smaller than the convex portions 4. A dotted line in FIG. 4 represents the size of the convex portion 4 with respect to the concave portion 5.

さらに、別体部３Ａは、音叉状端子３１の溝３２にヒューズの端子を確実に挟持できるよう、音叉状端子３１において良好なバネ性を得ることができる高価な金属材料で構成されている。これに対し、本体部２Ａは、バスバ１Ａ全体としてのコストを下げるため、別体部３Ａよりも安価な金属材料で構成されている。   Further, the separate part 3A is made of an expensive metal material that can obtain a good spring property in the tuning fork terminal 31 so that the terminal of the fuse can be securely held in the groove 32 of the tuning fork terminal 31. On the other hand, the main body 2A is made of a metal material that is cheaper than the separate body 3A in order to reduce the cost of the bus bar 1A as a whole.

このような構成のバスバ１Ａは、板部３０が凹み部２３内に打ち込まれて嵌め込まれるとともに凸部４が凹部５内に打ち込まれて嵌め込まれることにより、本体部２Ａと別体部３Ａとが互いに組み付けられて、板部３０の三つの外縁３０ｂ，３０ｃ，３０ｄ、即ち別体部３Ａの外縁３０ｂ，３０ｃ，３０ｄ、と、凹み部２３の三つの内縁２３ｂ，２３ｃ，２３ｄ、即ち本体部２Ａの外縁２３ｂ，２３ｃ，２３ｄ、とが密着する。   In the bus bar 1A having such a configuration, the main body 2A and the separate body 3A are formed by the plate portion 30 being driven and fitted into the recess 23 and the convex portion 4 being driven and fitted into the concave portion 5. The three outer edges 30b, 30c, and 30d of the plate portion 30, that is, the outer edges 30b, 30c, and 30d of the separate body portion 3A, and the three inner edges 23b, 23c, and 23d of the recess portion 23, that is, the main body portion 2A are assembled. The outer edges 23b, 23c, and 23d are closely attached.

このように、本発明のバスバ１Ａは、本体部２Ａと別体部３Ａとを重ね合わせて溶接するのではなく、板部３０と凹み部２３、そして、凸部４と凹部５、をプレス加工により嵌め合わせて、即ちかしめて、本体部２Ａと別体部３Ａとを組み付ける構成であるので、本体部２Ａと別体部３Ａとを同一平面上に配置することができ、その厚みを小さくすることができる。即ち、バスバ１Ａは、その厚みを金属板１枚分にすることができる。   Thus, the bus bar 1A of the present invention does not overlap and weld the main body portion 2A and the separate body portion 3A, but presses the plate portion 30 and the recessed portion 23, and the convex portion 4 and the recessed portion 5. Since the main body 2A and the separate body 3A are assembled by fitting together, that is, by caulking, the main body 2A and the separate body 3A can be arranged on the same plane, and the thickness thereof is reduced. be able to. That is, the thickness of the bus bar 1A can be made equal to one metal plate.

即ち、前述した「凹部５は、前記凸部４と等しい形状でかつ凸部４よりもわずかに小さく」の「わずかに」とは、凸部４が凹部５内に打ち込まれて嵌め込まれた際に、凸部４が凹部５から抜け落ちることなく、かつ、凸部４及び凹部５が破壊されない程度の量を意味する。   That is, “slightly” of “the concave portion 5 is the same shape as the convex portion 4 and slightly smaller than the convex portion 4” described above is when the convex portion 4 is driven into the concave portion 5 and fitted therein. In addition, it means an amount such that the convex part 4 does not fall out of the concave part 5 and the convex part 4 and the concave part 5 are not destroyed.

さらに、本発明のバスバ１Ａにおいては、本体部２Ａ及び別体部３Ａを金属板から打ち抜いて得る加工と、本体部２Ａと別体部３Ａとを互いに組み付ける加工と、が順送型の型内で行われる。このため、従来技術と比較してプレス加工後の後加工、即ち溶接、が不要になり、加工費を安くすることができる。   Further, in the bus bar 1A according to the present invention, the process of punching the main body 2A and the separate part 3A from the metal plate and the process of assembling the main body 2A and the separate part 3A to each other are in a progressive mold. Done in For this reason, compared with the prior art, post-processing after press working, that is, welding, becomes unnecessary, and the processing cost can be reduced.

上述のように形成されたバスバ１Ａは、電気接続箱のハウジング内に挿入され、該ハウジングに係止穴２２が係止することにより、ハウジングに取り付けられ、ヒューズ、リレー等と電気接続される。こうして組み立てられた本発明の電気接続箱は、厚みの小さいバスバ１Ａを備えているので、余分なスペースが不要であり、小型化を図ることができる。   The bus bar 1A formed as described above is inserted into the housing of the electrical junction box, and the latch hole 22 is latched in the housing, so that the bus bar 1A is attached to the housing and electrically connected to a fuse, a relay, and the like. Since the electrical junction box of the present invention assembled in this way is provided with the bus bar 1A having a small thickness, an extra space is not required and the size can be reduced.
