Electrical connection box to be mounted on a vehicle

摘要

An electrical connection box for a vehicle is to be mounted in an engine compartment and connected to a voltage source of the vehicle having a nominal maximum voltage of not less than 14V. The box has a casing (20) having a rear wall (20a) which in use is mounted against an upstanding wall of the vehicle, a front wall (20f) and side walls (20b) and a bottom wall (20g) sloping downwardly. The bottom wall has a water drainage hole (9) at its lowermost portion adjacent said rear wall. Electrical circuit insulation plates (12) are mounted with main faces parallel to the rear wall (20b) and bus bars are mounted on said main faces. Electrical relay receiving elements (6), electrical fuse receiving elements (7) and electrical connector receiving elements (8) are located on at least one of the and side walls. The arrangement reduces risk of problems due to water ingress. <IMAGE>
