Circuit and busboard connection for an electrical connection box

摘要

A circuit connection structure comprises an electronic circuit board 10 having a through-hole 15, the electronic circuit board 10 being provided with lead wires 12 or electric wires of electronic parts 14 in a manner straddling the through-hole 15, and an insulating board 1 provided with bus-bars 2 having upright pressure-contact knife-edges 3 electrically connected to the lead wires 12 or electric wires. The electronic circuit board 10 and the insulating board 1 are stacked up by relatively moving both the boards close to each other in such a condition that the pressure-contact knife-edges are passing through the through-hole, whereby the lead wires 12 or electric wires are pressure-welded to the respective pressure-contact knife-edges 3.
