Abstract
A device for the electrical contacting of a heating conductor through a housing of an exhaust gas line, having an electrical conductor, which is formed as a metal bolt, a metal outer sleeve, through which the electrical conductor is fed, and an insulator, which is arranged between the electrical conductor and the outer sleeve, wherein the outer sleeve is integrally bonded to the housing, wherein the heating conductor is formed by a metallic honeycomb body which is arranged inside the housing, wherein exhaust gas can flow through the housing along a main throughflow direction which corresponds to the axial extent of the housing, wherein the electrical conductor is aligned along the axial direction of extent of the housing.

-17. (canceled)
A set, comprising:
- a first stator unit, having:
- a first interconnection device configured to interconnect a stator winding to form a delta circuit, the first interconnection device having three connection rails configured to contact in each case one phase strand of the stator winding;
- and
- an insulation housing with a receiving structure configured to receive the three connection rails;
- and
- a second stator unit, having:
- a second interconnection device configured to interconnect a stator winding to form a star point circuit, the second interconnection device having three connection rails configured to contact in each case one phase strand of the stator winding,
- a star point rail configured to contact all phase strands of the stator winding;
- and
- an insulation housing with a receiving structure configured to receive the three connection rails and the star point rail;
- wherein the receiving structures of the first and second interconnection devices are of identical design, and/or wherein the insulation housings of the first and second interconnection devices are identical parts.
The set as claimed in claim 18,
- wherein the receiving structure has three receiving portions for the three receiving rails on an upper side of the insulation housing and a further receiving portion for the star point rail on a lower side of the insulation housing, and
- wherein the further receiving portion of the first interconnection device is unoccupied and the further receiving portion of the second interconnection device is occupied by the star point rail.
A stator unit, comprising:
- an interconnection device, the interconnection device having an insulation housing with a receiving structure, the receiving structure being formed for receiving three connection rails in order to form the interconnection device as a delta circuit, or for receiving three connection rails and a star point rail in order to form the interconnection device as a star circuit.
A method for manufacturing a stator unit comprising:
- Providing a stator body, a stator winding and an interconnection device for interconnecting the stator winding to form a delta connection or a star connection;
- when a delta circuit is to be produced, the stator winding is inserted into the stator body in a predefined first angular position and the interconnection device is arranged in a fixed angular position relative to the stator body, at least one winding end of a phase strand being contacted with a respective connection rail of the interconnection device in order to form a first stator unit;
- and
- if a star connection is to be produced, the stator winding is inserted into the stator body in a predefined second angular position, the interconnection device is supplemented by a star point bar and the interconnection device is arranged in a defined angular position relative to the stator body,
- wherein, to form a second stator unit, in each case at least one winding end of a phase strand is contacted with in each case one connection rail of the interconnection device and in each case at least one winding end of each phase strand is contacted with the star point rail.
