Abstract
To provide a seal for a conducting element (3) which is positioned eccentrically in a through-hole (2) in a housing wall (1), a proposal is made for a sealing body (8) which can be moved in a radial direction (11) and which can be fixed after assembly of the conducting element (3) by means of a clamping device (19).
Claims9
A sealing device comprising:
- a conducting element which can be inserted off-center in a through-hole having an inner side wall, said sealing device having a sealing body touching both the conducting element and the inner side wall;
- wherein in the region where the sealing body contacts the conducting element and the inner side wall, the cross-sectional profile of the conducting element has at least one first recess within which the sealing body can be moved in a radial direction;
- wherein the sealing body is attached to the conducting element by a positive retainer comprising:
- at least one engagement rib provided on the sealing body and at least one second recess in the conducting element, further comprising a sealing ring with an internal thread screwed onto the conducting element to fix the sealing body with respect to the inner side wall.

A method for sealing comprising the steps of:
- using a sealing device comprising a conducting element which can be inserted off-center in a through-hole having an inner side wall, and which has a sealing body touching both the conducting element and the inner side wall;
- wherein in the region where the sealing body contacts the conducting element and the inner side wall, the cross-sectional profile of the housing wall and the conducting element has at least one first recess within which the sealing body can be moved in a radial direction, to seal an eccentric through-hole for the conducting element;
- and
- attaching the sealing body to the conducting element by means of a positive retainer comprising:
- at least one engagement rib provided on the sealing body and at least one second recess in the conductor element, further comprising the step of:
- screwing a sealing ring with an internal thread onto the conducting element which comprises the at least one first recess to fix the sealing body.

A sealing device comprising:
- a conducting element which can be inserted off-center in a through-hole in a housing wall, said sealing device having a sealing body touching both the conducting element and the housing wall;
- wherein in the region where the sealing body contacts the conducting element and the housing wall, the cross-sectional profile of the conducting element has at least one recess within which the sealing body can be moved in a radial direction;
- wherein the sealing body has one axial seal located in the recess and a further radial seal which mates with a surface which bounds the space between the connector body and the housing wall;
- wherein a limiting stop is formed on the sealing body in a position which lies within the recess, wherein the limiting stop limits compression of the axial seal.
