<p><P>PROBLEM TO BE SOLVED: To reduce the size of a connector and to simplify the circuitry in a junction block being connected between the battery and inverter of an electric vehicle (including hybrid car). <P>SOLUTION: The circuit structure of a junction block A comprises bus bars 1 and 13 of + pole and bus bars 6 and 10-12 of - pole wherein connectors 21 and 26 of + pole are constituted by arranging a plurality of + pole terminals 2a-3a and 13a continuous to the + pole bus bar in one connector housing, and connectors 24 and 25 of - pole are constituted by arranging a plurality of - pole terminals 8a-9a and 10a-12a continuous to the - pole bus bar in the other connector housing. The bus bars 1 and 13 of + pole and the bus bars 6 and 10-12 of - pole are arranged in different layers through an insulating plate. The + pole bus bar 1 and the - pole bus bar 6 are continuous, respectively, to the total input section of a battery circuit and the total output sections 1a and 6a of an inverter circuit, and other output section has + pole terminals 2a and 3a and - pole terminals 8a and 9a. The total output sections 1a and 6a are arranged in the center of the junction block A. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
