Abstract: The invention relates to a rectifier unit comprising one plus cooling body (27) which supports at least one plus-diode (32), and one minus cooling body (28) which supports at least one minus diode (31). A spacer (29), which is made of an insulating material (70), electrically separates the plus cooling body (27) and the minus cooling body (28). A wiring plate (30) comprises at least one conductor element which enables the at least one plus-diode (32) and the at least one minus-diode (31) to be wired in a bridge rectifier circuit. Said conductor element is a flat webbed cable (33). According to the invention, the flat webbed cable (33) supports a bolt-like connection (48).
