Patent number: 7151427Abstract: A switchgear, especially for actuating valves, includes a housing (18) and a coil body (10) disposed in the housing. A switch element is guided in the coil body. The coil body is provided with a winding (14) of a conductor (16) that is connected to a plug connector (22) via contact elements (20). At least some sections of the housing (18) and of the plug connector (22) are enclosed by a plastic compound (24). Sealing devices (40) seal off the interior (42) of the switchgear from the surroundings (44). At least one of the sealing devices (40) is configured as a sealing web (48) of a meltable material. The sealing web (48) is disposed on the bottom face (50) of a plug plate (26) of the plug connector (22) which faces the housing (18).Type: GrantFiled: January 24, 2002Date of Patent: December 19, 2006Assignees: Hydac Electronic GmbH, Bosch Rexroth AGInventors: Michael Muller, Heinz Jacobus, Matthias Stitz, Bruno Schneider

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. KGInventors: Matthias Stitz, Karl-Heinz Wittig, Hans-Jürgen Kern

Patent number: 6784778Abstract: In a magnet coil arrangement having a wound coil former and having a metal housing surrounding the wound coil former, contact tabs are held in a plug-in base, one of which serves as a protective conductor connection. The contact tab serving as a protective conductor connection is held on the metal housing by a metallic connecting part. The free spaces between the wound coil former, the metal housing and the plug-in base are encapsulated with plastic. At the interfaces between the metal parts and plastic, moisture can enter the magnet coil arrangement. In order to prevent this moisture from getting into the connecting space, in which electric feed lines coming from the outside are connected to the contact tabs, in the area in which the connecting part engages in the contact tab, the contact tab serving as a protective conductor connection is arranged inside the plug-in base.Type: GrantFiled: November 13, 2002Date of Patent: August 31, 2004Assignee: Bosch Rexroth AGInventors: Matthias Stitz, Achim Richartz
