Etude acoustique de la dure de la gmination pour la parole arabe

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. Between the connecting part and the plug-in base there is arranged a sealing part, of which a first sealing face rests on the connecting part and a second sealing face rests on the plug-in base. The magnet coil arrangement is provided to operate valves which are used in fluid engineering.
