The present disclosure relates to an interconnection assembly for a stator of an electrical machine. The interconnection assembly comprises a shaped bus bar, which has a first region, which comprises a connection point of the interconnection assembly for an external connection, a second region, in which a connecting point for forming a connection of the bus bar to a stator winding is formed, and a central region, which connects the first region and the second region. The first region and the second region are arranged in parallel planes. The central region is oriented in such a way that an angle of a transition between the first region and the central region and an angle of a transition between the second region and the central region deviate from a right angle. The disclosure also relates to a stator having an interconnection assembly.

Interconnection assembly and stator for an electrical machine

The invention relates to a stator (IO) in an electric machine (I) with a laminated core (II) formed in an annular fashion about a central axis (A), on which core stator coils () with coil ends () are arranged by means of formers (). The stator (IO) comprises wiring device (), on which a plurality of mutually isolated connecting conductors (-) with coil connection areas (-) are present for connecting the stator coils (). The wiring device () is joined on the stator in an axial joining direction to the stator coils () and is secured by axial connection means () to the formers (), thus forming a plurality of axial connections (). According to the invention, to increase the stiffness of the stator (IO), radial supporting means () are additionally formed on the wiring device () to interact with the formers (), said means being designed to be functionally independent of the axial connection means ().
