Abstract

Busbar comprising a supporting body ( 1 ) made of a tough-hard material, and at least one electrical conductor ( 2.1, 2.2, 2.3 , . . . ), wherein the conductor ( 2.1, 2.2, 2.3 , . . . ) is connected to the supporting body ( 1 ). The supporting body ( 1 ) comprises a seal ( 3 ) that is made of a rubber-elastic material, which encloses the conductor ( 2.1, 2.2, 2.3 , . . . ) on the outer circumferential side with an annular sealing region ( 4 ) in a sealing manner.

Claims (25)

1. A busbar comprising:

a supporting body with a core having an outer circumference surrounded by a collar-shaped fastening flange, the core having a greater thickness than the fastening flange, the supporting body made of a tough-hard material; and

at least one electrical conductor connected to the supporting body, the conductor having an outer perimeter,

wherein the supporting body comprises a seal made of a rubber-elastic material and configured to enclose the outer perimeter of the conductor in a sealing manner, and

wherein the seal further comprises a flange region having an ‘L’ shaped cross-section, a first portion of the flange region abutting the fastening flange and a second portion of the flange region enclosing the circumference of the core in a sealing manner.

2. The busbar according to claim 1 , wherein the supporting body is comprised of a polymeric material.

3. The busbar according to claim 1 , wherein the seal is comprised of an elastomeric material.

4. The busbar according to claim 1 , wherein the supporting body and the seal are connected to one another with a substance-to-substance bond.

5. The busbar according to claim 1 , wherein the conductor comprises a copper-metal part.

6. The busbar according to claim 1 , wherein the conductor is configured as a plug.

7. The busbar according to claim 1 , wherein the conductor comprises a first leg and a second leg.

8. The busbar according to claim 7 , wherein the first leg and the second leg each have a contact at a free end, the free ends of each of the first leg and the second leg facing away from one another respectively.

9. The busbar according to claim 7 , wherein the conductor penetrates the supporting body with one of the first leg and the second leg.

10. The busbar according to claim 7 , wherein the core is penetrated by one of the first leg and the second leg.

11. The busbar according to claim 1 , wherein the configuration of the seal to enclose the outer perimeter of the conductor of the seal and the flange region of the seal merge integrally and comprise the same material.

12. The busbar according to claim 1 , wherein the ‘L’ shaped cross-section of the flange region is formed by the first portion and the second portion.

13. The busbar according to claim 12 , wherein the ‘L’ shaped cross-section of the flange region is formed by the seal leg and the another seal leg.

14. A busbar arrangement according to claim 12 , wherein the flange region further comprises a plurality of annular rings projecting from the second portion, the projection of the annular rings being toward the opening and configured to seal the housing and the supporting body.

15. The busbar according to claim 1 , wherein the first portion of the flange region comprises a seal leg abutting the fastening flange along a length of the seal leg and the second portion of the flange region comprises another seal leg enclosing the circumference of the core along a length of the another seal leg.

16. A busbar arrangement according to claim 15 , wherein the projection of the annular rings are configured to seal the housing and the supporting body against the egress of the liquid medium from the housing.

17. A busbar arrangement comprising:

a housing containing a liquid medium and having a top side defining an opening;

a busbar comprised of a supporting body with a core having an outer circumference surrounded by a collar-shaped fastening flange, the core having a greater thickness than the fastening flange and configured to project into the opening such that the fastening flange abuts the top side of the housing, the supporting body being made of a tough-hard material, and an at least one electrical conductor connected to the supporting body, the conductor having an outer perimeter; and

a seal made of a rubber-elastic material and configured to enclose the outer perimeter of the conductor in a sealing manner,

wherein the seal further comprises a flange region having an ‘L’ shaped cross-section, a first portion of the flange region being disposed between the fastening flange and the top side of the housing and a second portion of the flange region being disposed between the circumferential side of the core and the opening of the housing, the flange region configured to seal the housing against the surroundings of the housing such that the liquid medium of the housing will not leak to a surrounding area.
