FUSE CIRCUIT STRUCTURE FOR JUNCTION BOX

摘要

PROBLEM TO BE SOLVED: To improve flexibility for a specification change in a junction box. SOLUTION: In a fuse module 14 of the modularized junction box 10, bus-bars 20A, 20B for fuses are stacked vertically through an insulation plate 22. The bus-bar 20A for the fuse on the lower layer is used for a power circuit on the positive electrode, and the bus-bar 20B for the fuse on the upper layer is used for a load circuit on the negative electrode to standardize the polarity for the respective layers.
