<p><P>PROBLEM TO BE SOLVED: To reduce the size and simplify an electrical connection box where a PD is mounted, and further to enhance the heat dissipation. <P>SOLUTION: This is an electric connection box 10 which is to be mounted on an automobile. This is equipped with a PD where as the inner circuit members of the electric connection box 10, relays 17 and 21 are mounted on one side of printed boards 16 and 20 and are connected to printed conductors and bus bars 18 and 22 are fixed to the other side and heat radiating materials 19 and 23 are arranged on the bus bar fixed side. The above PD is divided into a PD14 for connection on battery side and a PD15 for connection on alternator side. The PD14 for connection on battery side and the PD15 for connection on alternator side are counterposed, with each heat radiating materials 19 and 23 directed outward. This is provided with a branch circuit block 13 consisting of a stack of a bus bar 25 and an insulating plate 24, in a region under each PD 14 and 15. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
