Embodiment
[0039] 1. The overall structure of the electrical junction box
[0040] Reference below Figure 1 to Figure 12 The electrical junction box 10 for a vehicle is described.
[0041] Such as figure 1 As shown, the electrical junction box 10 includes a circuit board 20 and a housing 30 . The circuit board 20 includes a printed circuit board and electronic components Z mounted on the printed circuit board. The circuit board 20 has a rectangular shape, and includes conductive wires (not shown) formed using a wire printing technique. A moisture-proof insulating coating is applied to the circuit board 20 after the electronic components Z are mounted thereon. For example, liquid resin is sprayed on the circuit board 20 to form a thin film on the circuit board 20 . Moisture does not affect the electrical performance of the circuit board 20 due to the coating.
[0042] The housing 30 holds the circuit board 20 therein. The case 30 includes a holding member (case element) 31 and a c...
