<p>PURPOSE: To reduce or eliminate mutual effect of electromagnetic trouble on different device groups by arranging a plurality of connection terminals between the device groups and connecting these connection terminals with conductors for bridging the upper part of one device group. CONSTITUTION: A control section 4 is arranged planarly, as a first device group 2, on a printed wiring board 1 while a power section 5 is arranged planarly as a second device group 3 and a plurality of connection terminals 7 are provided in the boundary region 6 between these device groups. These connection terminals 7 comprise terminal parts having a connecting region of a conductor path formed on the printed wiring board 1. Holes are made through the printed wiring board 1 and inserted with one end of conductors 8 which are then soldered to the connection terminals 7. The other end of the conductor 8 is led to a contact of a plug board 10 fixed to the circumferential part 9 of the printed wiring board. According to the arrangement, mutual effect of electromagnetic trouble between different device groups can be suppressed.</p> |
