【従来技術】[Prior art]

従来、自動車用電気接続箱内における導電体(バスバー)同志を電気的に接続 することは容易ではなく、そのような接続は殆ど行われていなかった。しかしな がら、近年、車両の軽量化、低コスト化などの要求が強くなり、それに伴い、電 気接続箱も小型化、軽量化、低コスト化する必要が出てきた。そこで、あえてバ スバー同志を電気的に接続する場合、例えば、次のような手段が用いられていた 。即ち、 1)図4に示すように、同一層内のバスバー1の先端部を曲げてタブ2を取り出 し、タブ2同志を外部短絡端子3を介して接続する。4は絶縁板、5は電気接続 箱のハウジングである。図5は、異なる層内のバスバー1を同様な方法で接続す る場合を示している。 2)図6に示すように、電気接続箱の端に短絡ピン6を内蔵させ、この短絡ピン 6により異なる層内にあるバスバー1を端部において接続する。 Conventionally, it is not easy to electrically connect conductors (bus bars) in an electric junction box for automobiles, and such a connection has been rarely made. However, in recent years, there has been an increasing demand for weight reduction and cost reduction of vehicles, and along with this, it has become necessary to reduce the size, weight and cost of the electrical junction box. Therefore, for example, the following means were used to electrically connect the busbars together. That is, 1) As shown in FIG. 4, the tip of the bus bar 1 in the same layer is bent to take out the tab 2, and the tabs 2 are connected to each other via the external short-circuit terminal 3. Reference numeral 4 is an insulating plate, and 5 is a housing of an electrical junction box. FIG. 5 shows a case where bus bars 1 in different layers are connected in the same manner. 2) As shown in FIG. 6, a short-circuit pin 6 is built in the end of the electric junction box, and the bus-bars 1 in different layers are connected at the end by this short-circuit pin 6.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、上述のような手段には次のような問題があった。即ち、 1)第1の方法でバスバーのタブを立てたり、あるいは、バスバーの接続を減ら すために、1個のバスバーに多くの回路を入れると、バスバーが大型になり、ま た、設計に無理が生じて、プレス加工によるバスバーの製造コストが上昇する。 2)第2の方法では、電気接続箱の構造が複雑化し、そのコストが上昇する。 However, the above means has the following problems. That is, 1) If many circuits are put in one busbar in order to stand up the tabs of the busbar or reduce the connection of the busbar by the first method, the busbar becomes large, and the design becomes Excessiveness increases the manufacturing cost of the bus bar by pressing. 2) In the second method, the structure of the electric junction box becomes complicated and the cost thereof rises.

In the connection structure of conductors in the box, the first invention is that conductors in the same layer or in different layers are connected to each other by ultrasonic welding, and conductors in the same layer or in different layers are considered. The second invention is that the two are connected to each other by a bonding wire. As described above, when the conductors are connected by ultrasonic welding or by bonding wires that are ultrasonically welded, the conductors in the same layer or different layers can be efficiently connected. Also, since the electrical reliability is high, the design pattern of the conductor can be rationalized and the electric junction box can be downsized.
