Abstract

A plug connector for charging an electric vehicle includes: a housing, which delimits a housing interior chamber; a cable, which is led through an opening in the housing into the housing interior chamber; and a seal, which seals the housing interior chamber between the cable and the housing. The seal has a sealing lip enclosing the cable and contacting the cable. The seal has a sealing ridge enclosing the cable and contacting the housing.

First claim

The invention claimed is:

1. A plug connector for charging an electric vehicle, comprising:
a housing, which delimits a housing interior chamber;
a cable, which is led through an opening in the housing into the housing interior chamber; and
a seal, which is configured to seal the housing interior chamber between the cable and the housing,
a protective cap, which covers the seal and is connected to the housing,
wherein the seal has a sealing lip enclosing the cable and contacting the cable,
wherein the seal has a sealing ridge enclosing the cable and contacting the housing, and
wherein one outlet opening or a plurality of outlet openings configured to discharge liquids is formed between the protective cap and the seal.

2. The plug connector of claim 1 , wherein the sealing lip is tapered in an end section contacting the cable.

3. The plug connector of claim 1 , wherein the seal has a second sealing lip enclosing the cable and contacting the cable, the second sealing lip being tapered in an end section contacting the cable.

4. The plug connector of claim 1 , wherein the sealing ridge has a sealing bead or a plurality of sealing beads.

5. The plug connector of claim 1 , wherein the sealing ridge contacts the cable.

6. The plug connector of claim 1 , wherein the seal has a second sealing ridge, the second sealing ridge having a sealing bead or a plurality of sealing beads.

7. The plug connector of claim 6 , wherein the seal has a recess, in which a ridge of the housing engages, and/or
wherein the housing has a recess, in which a sealing ridge of the seal engages.

8. The plug connector of claim 7 , wherein the sealing ridge and the second sealing ridge delimit the recess and contact the ridge of the housing.

9. The plug connector of claim 1 , wherein the protective cap contacts the seal in one region or in a plurality of regions.
