CUTTING MODULE COMPRISING A VACUUM BULB AND FIXING MEANS, AND ELECTRICAL CUTTING APPARATUS COMPRISING SUCH A MODULE

Device for automatically breaking the set of electric current circuits for motor vehicles

The invention relates to the technical field of transport, and in particular to motor vehicles. This device comprises a housing 1 connected to the positive terminal P of the accumulator battery 2 with, internally, at least two independent contacts 1a-1b and 1c-1d operated by reversed means M-Ma for automatic making and breaking which act automatically by inertia in the event of an accidental impact to the vehicle; one of the circuits C operated by the contacts 1a-1b, when closed by the means M, connecting the positive pole of the high-tension engine-starter coil B to the vehicle earth with the purpose of immediately stopping the engine, whereas the other circuit E operated by the contacts 1c-1d, when opened by the means Ma and in combination, cutting the supply circuits V of the vehicle. The invention is used by any type of motor vehicle and type of engine.

Un module de coupure pour appareillage électrique de coupure comporte une ampoule à vide 10 comportant un corps 17, et un bâti 12 de support de l'ampoule. L'ampoule est munie d'une tige métallique 32 mobile en translation et entraînant un contact mobile 24. Un collier 100 assure simultanément le positionnement radial du corps 17 de l'ampoule par rapport au bâti 12 et un fourreau de guidage de la tige 32. Pour son montage, le collier 100 peut être ouvert de manière à y introduire la tige 32 radialement. Une fois le corps de l'ampoule cerclé, le collier 100 est introduit radialement dans des rainures 130 de guidage du bâti.
