Abstract

The invention relates to a liquid extraction module ( 1 ) for extracting liquid from a liquid tank, in particular of an exhaust-gas aftertreatment system of a motor vehicle, having an insert part ( 2 ) which is produced at least substantially from plastic and which has at least one extraction opening ( 5 ) and at least one plug connector ( 14 ) for the electrical contacting of an electrical consumer ( 10, 7 ) of the liquid extraction module ( 1 ). It is provided that a housing ( 16 ) of the plug connector ( 14 ) is formed separately and has at least one encapsulated undercut ( 22, 32 ) for fastening to the insert part ( 2 ).

First claim

The invention claimed is:

1. A liquid extraction module ( 1 ) for extracting liquid from a liquid tank, having an insert part ( 2 ) which is produced at least substantially from plastic and which has at least one extraction opening ( 4 ) and at least one plug connector ( 14 ) containing contacts ( 24 ) for the electrical contacting of an electrical consumer ( 10 , 7 ) of the liquid extraction module ( 1 ), characterized in that a housing ( 16 ) of the plug connector ( 14 ) is formed separately from the insert part ( 2 ) and comprises at least one undercut ( 22 ) that is encapsulated by an intermediate piece ( 17 ) molded about the at least one undercut ( 22 ), the molded intermediate piece ( 17 ) being connected to the insert part ( 2 ) for fastening the housing ( 16 ) of the plug connector ( 14 ) to the insert part ( 2 ).

2. The liquid extraction module according to claim 1 , characterized in that the undercut ( 22 ) extends generally in a plugging direction of the plug connector ( 14 ).

3. The liquid extraction module according to claim 1 , characterized in that the housing ( 16 ) is produced from another material than that of the insert part ( 2 ) and the intermediate piece ( 17 ) from a material which can be welded to the insert part ( 2 ).

4. The liquid extraction module according to claim 1 , characterized in that the intermediate piece ( 17 ) is produced from the same material as the insert part ( 2 ).

5. The liquid extraction module according to claim 1 , characterized in that the undercut ( 22 ) extends over an entire width of the housing ( 16 ).

6. The liquid extraction module according to claim 1 , characterized in that the housing ( 16 ) of the plug connector ( 14 ) has at least one expansion ( 18 ) which, viewed in cross-section, is funnel-shaped and forms the undercut ( 22 ).

7. The liquid extraction module according to claim 1 , characterized in that the insert part ( 2 ) and/or the intermediate piece ( 17 ) are produced from high-density polyethylene.

8. The liquid extraction module according to claim 1 , characterized in that the housing ( 16 ) is produced from polyamide.

9. A liquid tank having a tank opening and comprising a liquid extraction module ( 1 ), which is disposed in/on the liquid tank so as to close the tank opening, and which has an extraction opening ( 4 ) associated with the tank interior, and at least one plug connector ( 14 ), which is accessible from outside the tank, for the electrical contacting of an electrical consumer ( 10 , 7 ) of the liquid extraction module ( 1 ), the liquid extraction module ( 1 ) further including an insert part ( 2 ) which is produced at least substantially from plastic and which includes the extraction opening ( 4 ), the at least one plug connector ( 14 ) having a housing ( 16 ) formed separately from the insert part ( 2 ) and comprises at least one undercut ( 22 ) that is encapsulated by an intermediate piece ( 17 ) molded about the at least one undercut ( 22 ), the molded intermediate piece ( 17 ) being connected to the insert part ( 2 ) for fastening the housing ( 16 ) of the plug connector ( 14 ) to the insert part ( 2 ).

10. The liquid extraction module according to claim 1 , characterized in that the plastic of the insert part ( 2 ), of the housing ( 16 ) and/or of the intermediate piece ( 17 ) comprises a bonding agent.

11. The liquid extraction module according to claim 1 , characterized in that the plastic of the insert part ( 2 ), of the housing ( 16 ) and/or of the intermediate piece ( 17 ) comprises maleic anhydride.

12. The liquid extraction module according to claim 1 , characterized in that the undercut ( 22 ) extends over a circumference of the housing ( 16 ).

13. The liquid extraction module according to claim 1 , characterized in that the housing ( 16 ) is produced from polyamide with glass fiber reinforcement.
