Wiring assembly comprising a positioning device, use of the positioning device, and method for mounting the wiring assembly

An interconnection arrangement for an electric machine, with a multiphase stator winding, which has at least one winding end per phase, wherein the winding ends extend in an axial direction with reference to a stator axis, an interconnection device comprising:

• an insulation housing that is electrically insulating;
• a connection unit arranged at least partially in the insulation housing and configured to electrically contact the winding ends with a high-voltage terminal, wherein the connection unit has a plurality of conductor portions which extend in a same direction as the winding ends and are electrically conductively contacted with at least one winding end in each instance;
• a positioning device configured to position the winding ends in a correct position at a respective associated conductor portion;
• and
• at least one centering connection configure to center the positioning device in the correct position with respect to the interconnection device.

A method for assembling an interconnection arrangement having an insulation housing that is electrically insulating;

• a connection unit arranged at least partially in the insulation housing and configured to electrically contact winding ends with a high-voltage terminal, wherein the connection unit has a plurality of conductor portions which extend in a same direction as the winding ends and are electrically conductively contacted with at least one winding end in each instance;
• a positioning device configured to position the winding ends in a correct position at a respective associated conductor portion;
• and at least one centering connection configure to center the positioning device in the correct position with respect to an interconnection device, comprising:
• providing a stator winding;
• pre-mounting the positioning device at the winding ends, wherein the winding ends are pre-aligned by the positioning device;
• and
• connecting the interconnection device and the positioning device to one another in axial direction with reference to a stator axis and are centered in correct position relative to one another via the at least one centering connection.
