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

Busbar and arrangement comprising such a busbar

A plug-in piecefor sealing connection of two mutually assigned cylindrical surfaces includes an essentially tubular support body, which on its ends exhibits annularly encircling sealing elements, which can be made to engage to produce a sealing connection with the cylindrical surfaces to be sealed, wherein at least one of the sealing elements is configured as an annularly encircling sealing beadon the outer surface of the support body, with a spherically curved sealing surface. Provision is made that the spherical radius of the sealing surface () is chosen so that the center of the sphere is roughly at the axis of support body () symmetry. Thus, the compression forces are ensured to remain largely constant, independent of the angular setting over the entire surface of the sealing bead.

Plug-in piece

A seal including a tubular carrier body () and two annular sealing elements (), wherein the carrier body () on both sides of its front face is respectively enclosed by one of the sealing elements () on the side of its outer perimeter forming a seal. At least one of the sealing elements () is made of a non-elastomeric high-temperature resistant sealing material.
