Abstract
An electrical connection box is provided for a vehicle which has a low-voltage battery of maximum output voltage selected from a range of from about 14V to about 28V, and a high-voltage battery of output voltage higher than that of the first battery structure. The electrical connection box has an insulation material of plate-like shape and, embedded in the insulation material, first bus bars connected in use to the first battery and second bus bars connected in use to the second battery so that the first and second bus bars are at different potentials. Connection tabs of the bus bars project out of the insulation material. Risk of leakage currents between the bus bars is thus minimized.
Claims12
A vehicle comprising:
- an internal combustion engine providing motive drive of the vehicle;
- a first, low-voltage battery structure comprising at least one secondary battery, and having a nominal maximum output voltage of from about 14V to about 28V;
- a second, high-voltage battery structure comprising at least one secondary battery, and having a nominal maximum output voltage higher than that of said first battery structure and not more than about 200V;
- a plurality of electrical devices powered by said first and second battery structures;
- and
- an electrical connection box containing an electrical circuit therein which effects connection between said first and second battery structures and said plurality of electrical devices,
- said electrical circuit comprising an insulation material in a generally planar shape and, embedded in said insulation material, at least one first bus bar connected to said first battery structure and at least one second bus bar connected to said second battery structure, said first and second bus bars being at different potentials in operation, said insulation material electrically insulating said first and second bus bars from each other, and
- wherein each of said first and second bus bars has at least one connection tab projecting through said insulation material.
An electrical connection box adapted for use in a vehicle which includes a first, low-voltage battery structure comprising at least one secondary battery, and having a nominal maximum output voltage of from about 14V to about 28V, and a second, high-voltage battery structure comprising at least one secondary battery, and having a nominal maximum output voltage higher than that of said first battery structure and not more than about 200V,
- said electrical connection box containing an electrical circuit comprising an insulation material in a generally planar shape and, embedded in said insulation material, at least one first bus bar connected to said first battery structure and at least one second bus bar connected to said second battery structure, said first and second bus bars being at different potentials in operation, and
- wherein each of said first and second bus bars has at least one connection tab projecting out of said insulation material.
A vehicle comprising:
- an internal combustion engine providing motive drive of the vehicle;
- a first, low-voltage battery structure comprising at least one secondary battery, and having a nominal maximum output voltage of from about 14V to about 28V;
- a second, high-voltage battery structure comprising at least one secondary battery, and having a nominal maximum output voltage higher than that of said first battery structure and not more than about 200V;
- a plurality of electrical devices powered by said first and second battery structures;
- and
- an electrical connection box containing an electrical circuit therein which effects connection between said first and second battery structures and said plurality of electrical devices,
- said electrical circuit comprising an insulation material in a generally planar shape and, embedded in said insulation material, at least one first bus bar connected to said first battery structure and at least one second bus bar connected to said second battery structure, said first and second bus bars being at different potentials in operation, said insulation material electrically insulating said first and second bus bars from each other, and
- wherein each of said first and second bus bars has at least one connection tab projecting out of said insulation material, wherein said insulation material of said electrical circuit includes a flat plate member having a surface on which said first and second bus bars are mounted and at least one body of molded resin material on said surface of said plate member, and wherein the at least part of each of said first and second bus bars are embedded between said surface and said resin material with said tabs thereof projecting out from said resin material away from said surface.
