この構成により、電気接続箱１及びワイヤハーネス２は、バスバ２３、２６が締結柱３２ｅの側面部３２ｊ、３２ｒに沿って延在するので、配索面３２ｆ以外の部分で沿面距離を稼ぐことができる。この構成により、電気接続箱１及びワイヤハーネス２は、バスバ２３、２６が配索面３２ｆに延在することを抑制することができる。つまり、電気接続箱１及びワイヤハーネス２は、側面部３２ｊ、３２ｒにより沿面距離を稼ぐことができるので、その分配索面３２ｆにおける沿面距離を抑制することが可能となり、当該配索面３２ｆの大型化を抑制することができる。また、電気接続箱１及びワイヤハーネス２は、配索面３２ｆに設けられる絶縁リブ３２ｐを可能な限り省略することができる。この結果、電気接続箱１及びワイヤハーネス２は、筐体３０の配索面３２ｆを相対的に小さくすることが可能となり、電気接続箱１を設置する設置領域が拡大することを抑制できる。 With this configuration, in the electric junction box 1 and the wire harness 2, since the bus bars 23 and 26 extend along the side surface portions 32j and 32r of the fastening pillar 32e, it is possible to increase the creepage distance in the portion other than the wiring surface 32f. can. With this configuration, the electrical connection box 1 and the wire harness 2 can prevent the bus bars 23 and 26 from extending to the wiring surface 32f. That is, since the electric junction box 1 and the wire harness 2 can increase the creepage distance by the side surface portions 32j and 32r, it is possible to suppress the creepage distance on the distribution rope surface 32f, and the large size of the distribution rope surface 32f. It is possible to suppress the formation. Further, in the electric connection box 1 and the wire harness 2, the insulating rib 32p provided on the wiring surface 32f can be omitted as much as possible. As a result, in the electric connection box 1 and the wire harness 2, the wiring surface 32f of the housing 30 can be made relatively small, and it is possible to suppress the expansion of the installation area in which the electric connection box 1 is installed.

上記電気接続箱１は、Ｌ字状に形成された第１及び第２Ｌ字端子１１ｃ、１２ｃを備える。第１Ｌ字端子１１ｃは、高さ方向に沿って延在し第１コネクタ部１１の第１配索線１１ｂに接続される第１端子部１１ｅ、及び、第１端子部１１ｅの端部から高さ方向に交差する方向（奥行き方向）に沿って延在する第２端子部１１ｆを有する。そして、第１Ｌ字端子１１ｃは、第１端子部１１ｅが第１コネクタ本体１１ａと側面部３２ｊとの間で当該側面部３２ｊに対向し、且つ、第２端子部１１ｆが頂部３２ｉに対向した状態で、第２端子部１１ｆがバスバ２３、２６に接続される。この構成により、電気接続箱１は、第１コネクタ部１１の第１配索線１１ｂが高さ方向に沿って第１端子部１１ｅに接続されるので、第１配索線１１ｂの長さの誤差を吸収することができる。つまり、電気接続箱１は、第１配索線１１ｂに余剰が生じても当該第１配索線１１ｂを高さ方向の下側に延在させることで、余剰分を吸収することができる。この構成により、電気接続箱１は、第１コネクタ部１１の組み付け性を向上させることができる。なお、第２Ｌ字端子１２ｃは、第１Ｌ字端子１１ｃと同等に構成され、第１Ｌ字端子１１ｃと同等の作用効果を有する。 The electrical connection box 1 includes first and second L-shaped terminals 11c and 12c formed in an L shape. The first L-shaped terminal 11c extends from the ends of the first terminal portion 11e extending along the height direction and being connected to the first wiring line 11b of the first connector portion 11 and the first terminal portion 11e. It has a second terminal portion 11f extending along a direction (depth direction) intersecting the vertical direction. The first L-shaped terminal 11c is in a state in which the first terminal portion 11e faces the side surface portion 32j between the first connector main body 11a and the side surface portion 32j, and the second terminal portion 11f faces the top portion 32i. Then, the second terminal portion 11f is connected to the bus bars 23 and 26. With this configuration, in the electrical connection box 1, the first wiring line 11b of the first connector portion 11 is connected to the first terminal portion 11e along the height direction, so that the length of the first wiring line 11b is increased. The error can be absorbed. That is, even if the first wiring line 11b has a surplus, the electrical connection box 1 can absorb the surplus by extending the first wiring line 11b downward in the height direction. With this configuration, the electrical connection box 1 can improve the assembling property of the first connector portion 11. The second L-shaped terminal 12c is configured in the same manner as the first L-shaped terminal 11c, and has the same effect as the first L-shaped terminal 11c.
