Abstract: An electronic system includes a casing including a first bearing surface, a first busbar attached to the casing and including a first connection end having a first connection surface, and an electronic unit having a second bearing surface and including a second busbar having a second connection end having a second connection surface. The second bearing surface is intended to slide on the first bearing surface when the electronic unit is inserted into the casing. One from among the first bearing surface and the second bearing surface includes a ramp that is inclined relative to the insertion direction for deforming the second busbar so as to bring the second connection surface closer to the first connection surface when the electronic unit is inserted into the casing. An electrical assembly may include such an electronic system and a rotary electric machine.

Abstract: An inverter unit (100) includes an inverter (110), an inverter housing (120) and an insulating member (130). The inverter (110) drives an electric motor (200) and includes at least one power module (112) for converting a High Voltage (HV) Direct Current (DC) to a three-phase Alternating Current (AC) that drives the electric motor (200). The inverter housing (120) receives the inverter (110). The power module (112) is mounted on an end wall (120a) of the inverter housing (120) by means of bolts (114). The insulating member (130) corresponding to each bolt (114) is disposed between a head portion (114a) of the corresponding bolt (114) and the power module (112).
