Electric connection box
First Claim
1. An electric connection box, comprising:
- a case;
a bus bar board including a plurality of bus bars, the bus bar board constituting a first electric power circuit and being accommodated in said case;
a heat radiation member accommodated in said case and having a portion exposed outside said case;
a plurality of heat radiation member-side bus bars connected to a first surface of said heat radiation member and constituting a second electric power circuit that connects to said first electric power circuit;
a plurality of switching devices mounted on said heat radiation member-side bus bars;
portions of said heat radiation member-side bus bars extending to form heat radiation member-side electrical component connection terminals;
portions of said bus bar board-side bus bars extending from said bus bar board near a position of said heat radiation member-side electrical component connection terminals and along a direction of said heat radiation member-side electrical component connection terminals to form bus bar board-side electrical component connection terminals;
electrical components being bridged between said heat radiation member-side electrical component connection terminals and said bus bar board-side electrical component connection terminals.

Abstract
In an electric connection box containing a bus bar board in a case, heat radiation member-side bus bars are connected to a heat radiation member, and switching devices, such as FETs, are mounted on the bus bars. The heat radiation member-side bus bars may project beyond an end surface of the heat radiation member, and form heat radiation member-side electrical component connection terminals. Electrical component connection bus bars project from a bus bar board to form bus bar board-side electrical component connection terminals. Electrical components are bridged between the heat radiation member-side electrical component connection terminals and the bus bar board-side electrical component connector terminals.
