CONTACT ARRANGEMENT HAVING A BATTERY AND AN ELECTRICAL LINE
First Claim
1. A contact arrangement having a battery and an electrical line, the battery having a connection terminal for connecting the electrical line, the electrical line having a connection piece for connection to the connection terminal, the connection piece or the connection terminal having a permanent magnet, characterized in that the connection terminal or the connection piece has an electromagnet having a core and a magnet coil, in that the permanent magnet of the connection terminal or the connection piece is associated with the electromagnet of the connection piece or of the connection terminal, the permanent magnet exerting a magnetic force for the purpose of retaining or repelling the core, and in that the electromagnet counteracts the force effect of the permanent magnet owing to the supply of current, such that it is possible for the connection terminal to attract or repel the connection piece.

Abstract
The invention discloses a contact arrangement which has a connection terminal and a connection piece. Permanent magnets are arranged in the connection terminal or in the connection piece, and electromagnets are arranged in the connection piece or in the connection terminal. In each case one contact piece is introduced in the connection terminal and in the connection piece and these contact pieces are in electrically conductive contact with one another in the event of a magnetic attracting force between the connection terminal and the connection piece. The electromagnets are electrically conductively connected to a control device. The permanent magnets and the cores of the electromagnets are matched to one another in such a manner that either a magnetic attracting force or a magnetic repelling force exists between the connection terminal and the connection piece without a current being applied to the electromagnet. If a current is now applied to the electromagnets, the magnetic force effect produced by the permanent magnets is inverted. In this manner it is possible for the control device, when identifying an emergency situation, to interrupt the electrical contact between the connection terminal and the connection piece, i.e. between a battery and a vehicle electrical system, by current being applied to the electromagnets.
