Patent number: 6848919Abstract: According to the invention, the coil of a magnet coil arrangement has a coil body which comprises a winding (14) and is extruded with plastic (17). A plug-in base with contact connectors is formed on the coil, wherein one of the connectors is used for connection of the grounding conductor (18). A metallic housing is placed over the coil. Connection of said metallic housing to the contact connector associated to the grounding conductor is achieved by means of a connection element which is guided through a recess of the plug-in base. A sealing element (42) disposed between the connection element and the recess prevents penetration of a fluid from a region between the metallic housing and the coil, into the region where a connector is connected to the contact connectors.Type: GrantFiled: April 3, 2002Date of Patent: February 1, 2005Assignees: Bosch Rexroth AG, Kern Technik GmbH & Co.
