<p>An electrical connection box for use in a vehicle, particularly a car, has a casing (11) and a stack of bus bars (16,17,18) and insulation plates (13,14,15) alternating in the vertical direction. For drainage of water penetrating onto the stack, each insulation plate has a drainage aperture (13a,14a,15a) and a drainage wall (13d,14d,15d) extending downwardly from its aperture so as to define and surround a drainage passage. At least each of the insulation plates other than the topmost one has on its upper surface a flow interruption rib upstanding continuously around its drainage aperture. Water on one bus bar cannot connect the bus bar conductively to another bus bar. <IMAGE></p> |
