Abstract

A cable connection (16) for a dosing module (6) for exhaust gas reduction, with a dosing module end (16b), which is designed for connection to the dosing module (6), and an end (16a) distant from the dosing module, comprising at least one electrical cable (19a, 19b) having at least one electrical conductor (28a, 28b) and a cable insulation (15a, 15b) surrounding the at least one electrical conductor (28a, 28b). The cable connection (16) is crimped in one region (26a) at the dosing module end (16b) of the cable connection (16). In the crimped region, a space (36) between the at least one electrical conductor (28a, 28b) and the cable insulation (15a, 15b) surrounding the at least one electrical conductor (28a, 28b) is filled with a silicone material (17a, 17b).

First claim

The invention claimed is:

1. A cable connection ( 16 ) for a dosing module ( 6 ) for exhaust gas reduction, the cable connection comprising a dosing module end ( 16 b ), which is configured to be connected to the dosing module ( 6 ), and an end ( 16 a ) distant from the dosing module,
wherein the cable connection ( 16 ) also comprises at least one electrical cable ( 19 a , 19 b ) having at least one electrical conductor ( 28 a , 28 b ) and a cable insulation ( 15 a , 15 b ) surrounding the at least one electrical conductor ( 28 a , 28 b );
wherein the cable connection ( 16 ) is crimped in a crimped region ( 26 a ) at the dosing module end ( 16 b ) of the cable connection ( 16 ); and
wherein in the crimped region, a space ( 36 ) between the at least one electrical conductor ( 28 a , 28 b ) and the cable insulation ( 15 a , 15 b ) surrounding the at least one electrical conductor ( 28 a , 28 b ) is filled with a silicone material ( 17 a , 17 b ).

2. The cable connection ( 16 ) according to claim 1 , wherein the at least one electrical cable includes at least two electrical cables ( 19 a , 19 b ), wherein the electrical conductor ( 28 a , 28 b ) in each of the at least two electrical cables ( 19 a , 19 b ) is enclosed by a silicone material ( 17 a , 17 b ).

3. The cable connection ( 16 ) according to claim 1 , wherein the at least one electrical cable ( 19 a , 19 b ) comprises at least two electrical conductors ( 28 a , 28 b ), and wherein a space ( 38 ) between the at least two electrical conductors ( 28 a , 28 b ) is filled with the silicone material ( 17 a , 17 b ).

4. The cable connection ( 16 ) according to claim 1 , wherein the at least one electrical conductor ( 28 a , 28 b ) is connected to a connecting module ( 22 ) at the dosing module end ( 16 b ) of the cable connection ( 16 ).

5. The cable connection ( 16 ) according to claim 1 , wherein a plug connector ( 22 ) is provided at the end ( 16 a ) of the cable connection ( 16 ) distant from the dosing module.

6. The cable connection ( 16 ) according to claim 1 , wherein the space ( 36 ) between the at least one electrical conductor ( 28 a , 28 b ) and the surrounding cable insulation ( 15 a , 15 b ) is filled with a silicone material ( 17 a , 17 b ) also in a region ( 26 b ) at the end ( 16 a ) of the cable connection ( 16 ) distant from the dosing module.

7. A dosing module ( 6 ) configured to inject a reducing agent ( 10 ) into the exhaust gas line ( 2 ) of an internal combustion engine ( 4 ), the dosing module having a cable connection ( 16 ) according to claim 1 .

8. The dosing module ( 6 ) according to claim 7 , wherein the dosing module end ( 16 b ) of the cable connection ( 16 ) is electrically connected to the dosing module ( 6 ).

9. An exhaust gas line ( 2 ) of an internal combustion engine ( 4 ) having a dosing module ( 6 ) according to claim 7 .
