The disclosure concerns an electrical connection assembly comprising: a conductive plate with a drillhole, a first column with a hole passing axially through it and comprising a shoulder to abut against one of the faces of the conductive plate, and a second column with a hole passing axially through it and comprising a shoulder to abut against the other face of the conductive plate, a first cylinder with a radius sized to enable it to enter the hole in the first column and a length sized such that, when the shoulder is in abutment, the free end of the first cylinder projects beyond the conductive plate, and a second cylinder with a radius sized to enable it to enter the drillhole, wherein the free end of the first cylinder is crimped by radial expansion and then by axial compression in the hole in the first column.
