Abstract

Ce disjoncteur de batterie possède un conducteur de raccordement au réseau de bord (10) qui est relié avec le pôle plus de la batterie et mène directement au réseau de bord du véhicule, ainsi qu'un conducteur de raccordement à l'alternateur/démarreur (11) reliant par l'intermédiaire d'une paire de contacts (13, 14) le circuit alternateur/démarreur avec le pôle de la batterie. Cette paire de contacts (13, 14) est actionnée par un système d'électroaimant (25) qui est amené à se déclencher par exemple par un capteur de court-circuit ou un capteur d'impact (capteur d'airbag). Dans ce cas, le câble alternateur/démarreur est séparé de la batterie, tandis que le réseau de bord demeure en fonctionnement.
