<p><P>PROBLEM TO BE SOLVED: To reduce the size of an electric connection box comprising a power distributor (PD) and a branch circuit block by simplifying the circuit pattern being provided in the PD thereby reducing the size of the PD. <P>SOLUTION: The electric connection box comprises a power distributor (PD) 30 where electronic components including a semiconductor relay 35 and a substrate relay 36 are mounted on one side of a printed board 31 and connected with a conductor 32, one layer of bus bar 33 is secured to the other side and a heat dissipation metal plate 34 is fixed to the side arranged with the bus bar, and an encased branch circuit block 20 consisting of a laminate of the bus bar 21 and an insulating plate 22. Among the electric circuits in the case, the series circuit 50A of a fuse and a relay is provided on the PD 30 side, and the circuit 50B connected only with the fuse and branch circuits 50, 52 and 54 are formed of the bus bar 21 of the brach circuit block 20. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
