ABSTRACT:
A device for disconnecting the flow of current in the positive or impregnated battery cable of a motor vehicle has an electrically conductive plug-in connection that can be placed in the positive or impregnated battery cable in the form of a housing and a plug connector. The housing contains a gas generator of the kind used, for example, for belt tighteners. The gas generator is arranged in the housing in such a way that the propellant gas produced when the gas generator is ignited electrically separates the connector from the housing and this in turn interrupts the flow of current in the positive or impregnated battery cable. Consequently, a short circuit that might occur in the event of an accident and which could otherwise lead to damage of the cable tree and then set the vehicle on fire, is avoided in good time.
