Abstract
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.
Claims16
An electrical connection box, comprising:
- a first bus bar to which a first voltage may be applied and a second bus bar to which a second voltage not lower than said first voltage may be applied;
- a first insulation plate on which both said first and second bus bars are mounted;
- and
- a second insulation plate superimposed on said first insulation plate, wherein said first insulation plate provides, at least at a region where said first and second bus bars are adjacent, groove structures in which said first and second bus bars are respectively received, each said groove structure being defined by a base wall surface on which the respective bus bar is disposed and a pair of opposed upstanding side wall surfaces, and said first insulation plate further provides a concavity in the form of a downward recess or a through-hole located between said groove structures, and said second insulation plate having a downward projection received in said concavity, said downward projection having a lower end which is located at a level lower than said base wall surface of said groove structure.
A vehicle having an electrical connection box, comprising:
- a first bus bar to which a first voltage may be applied and a second bus bar to which a second voltage not lower than said first voltage may be applied;
- a first insulation plate on which both said first and second bus bars are mounted;
- and
- a second insulation plate superimposed on said first insulation plate, wherein said first insulation plate provides, at least at a region where said first and second bus bars are adjacent, groove structures in which said first and second bus bars are respectively received, each said groove structure being defined by a base wall surface on which the respective bus bar is disposed and a pair of opposed upstanding side wall surfaces, and said first insulation plate further provides a concavity in the form of a downward recess or a through-hole located between said groove structures, and said second insulation plate having a downward projection received in said concavity, said downward projection having a lower end which is located at a level lower than said base wall surface of said groove structure.
