接続箱が大型化する等の問題点があった。However, in the conventional electrical junction box constructed as described above, the pitch P between the tabs 24 formed on the bus bar 23 is set in a horizontal row as shown in FIG. Blade type fuse F to be placed,
Since it is wider than the pitch between F (for example, most of the pitches when the small blade-type fuses are arranged in the horizontal column are 10 to 12 mm), between the tabs 24 formed by bending the bus bar 23, the lower layer is formed. The tabs 24 'of the busbars arranged on the insulating substrate 22' must be positioned. For this reason, not only the through hole 22a for inserting the tab 24 'of the lower busbar must be formed in the upper insulating board 22, but the number of insulating boards stacked and the number of busbars are increased, which is extremely uneconomical. In addition, there is a problem that the electric junction box becomes large.
