Abstract
Official abstract text for this publication.
A sealing arrangement includes: a first machine element and a second machine element, each made of an electrically-conductive material; and a seal. The first and second machine elements are sealed against one another by the seal. At least one of the machine elements is made of an electrically-conductive plastic which is at least partially covered by an electrically-insulating, injection-molded skin as a result of production. The seal has an electrically-conductive support body. The support body has at least one substantially mandrel-shaped projection comprising an electrically-conductive material which is arranged on a side of the support body facing the injection-molded skin and completely penetrates the injection-molded skin.
First claim
Opening claim text (preview).
What is claimed is: 1. A sealing arrangement, comprising: a first machine element and a second machine element, each comprising an electrically-conductive material; and a seal, wherein the first and second machine elements are sealed against one another by the seal, wherein at least one of the machine elements comprises an electrically-conductive plastic which is at least partially covered by an electrically-insulating, injection-molded skin as a result of production, wherein the seal comprises an electrically-conductive support body, and wherein the support body comprises at least one substantially mandrel-shaped projection comprising an electrically-conductive material which is arranged on a side of the support body facing the injection-molded skin and completely penetrates the injection-molded skin. 2. The sealing arrangement according to claim 1 , wherein the support body and the projection transition into one another in one piece and comprise a uniform material. 3. The sealing arrangement according to claim 1 , wherein the support body and the projection comprise a metallic material. 4. The sealing arrangement according to claim 1 , wherein the seal comprises a flat seal. 5. The sealing arrangement according to claim 1 , wherein the at least one machine element comprises a housing part of a housing. 6. A method, comprising: using the sealing arrangement according to claim 1 , wherein the first and second machine elements form housing parts of a housing and enclose, in an electromagnetically-shielding manner, an electrical component emitting electromagnetic interference waves.
