Housing of an exhaust system of an internal combustion engine, electric heating unit for it, and use of a temperature-resistant electrical connection

Abstract

Housing (1, 1.1) of an exhaust system of an internal combustion engine, into which an electric heating unit (H, H.1) is inserted, with a temperature-resistant electrical connection (4, 4.1) inserted into a housing wall of the housing (1, 1.1), which electrical connection (4, 4.1) comprises a rod-shaped electrical conductor (7, 7.1) extending from the electrical load located inside the housing (1, 1.1) through the housing wall and located in a temperature-resistant electrical insulation (9) in the area of ​​the housing wall penetration (5), and which has a connection contact (8, 8.1) provided outside the housing for connecting the electrical conductor (7, 7.1) to a power supply, wherein the electrical conductor (7, 7.1) is located in a sheathing sleeve (6, 6.1) in the area of ​​its housing wall penetration and between the sheathing surface of the conductor (7, 7.1) and the sheathing sleeve (6, 6.1).1) the temperature-resistant electrical insulation (9) is arranged, wherein the terminal contact (8, 8.1) of the electrical conductor (7, 7.1) is provided in a section of the conductor (7, 7.1) located outside the sheath sleeve (6, 6.1), wherein the terminal contact (8, 8.1) or a part of this section is formed relative to its section extending through the housing wall to form a contact shoe by increasing its width through a forming process, and wherein at least one of the two flat sides of the terminal contact (8, 8.1) provides a contact surface (10) for connecting a mating contact (13) for supplying power to the electrical load.
