Electrical connection box for a vehicle

摘要

An electrical connection box for a vehicle has a low-voltage bus bar and a high voltage bus bar, received in groove structures of a first insulation plate. Each groove structure is defined by a base wall surface on which the bus bar is disposed and a pair of opposed upstanding side wall surfaces. The first insulation plate has a downward recess or through-hole between the groove structures. A second insulation plate superimposed on the first plate has a downward projection received in the recess or through-hole and extending to a lower end which is below the base wall surfaces of the groove structures. The structure inhibits leak currents between the bus bars.
