SEAL FOR AN ELECTRICAL PLUG DEVICE AS WELL AS HOUSING ASSEMBLY, ELECTRICAL PLUG DEVICE AND CASTING TOOL
A seal for an electrical plug device is provided including a through-opening for passing through an electrical conductor of the electrical plug device, wherein the through-opening extends along a hole axis and, in the through-opening, a sealing protrusion is arranged which extends in a closed manner and at least sectionally obliquely to a normal plane of the hole axis around the hole axis. Due to the at least sectional obliqueness of the sealing protrusion, a lead-in chamfer is created which facilitates the passing through of the electrical conductor through the through-opening. A housing assembly and an electrical plug device with such a seal are further provided. A casting tool for manufacturing such a seal is provided.

2 . Seal according to claim 1 , wherein the sealing protrusion extends seamlessly around the hole axis.
3 . Seal according to claim 1 , wherein a section of the sealing protrusion is offset in the direction of the hole axis from another section of the sealing protrusion.
4 . Seal according to claim 1 , wherein the sealing protrusion extends along an extension plane which is inclined with respect to the hole axis.
5 . Seal according to claim 1 , wherein the through-opening is adapted as a round circular hole and the sealing protrusion forms, at least sectionally, a circular segment, annular segment or toroidal segment.
6 . Seal according to claim 1 , wherein the through-opening is adapted as an oval oblong hole, the longitudinal direction of which extends perpendicular to the hole axis, and wherein the sealing protrusion forms, at least sectionally, a straight segment extending parallel to the longitudinal direction of the oblong hole.
7 . Seal according to claim 6 , wherein the straight segment extends parallel to the normal plane of the hole axis.
8 . Seal according to claim 1 , wherein the sealing protrusion has two sections opposite each other with respect to the hole axis.
9 . Seal according to claim 1 , wherein a second sealing protrusion is arranged in the through-opening, the sealing protrusion and the second sealing protrusion extend parallel to one another.
10 . Seal according to claim 1 , wherein the seal has a second through-opening with a second sealing protrusion and wherein the sealing protrusion and the second sealing protrusion extend parallel to one another.
