Abstract

The invention relates to a device for pyromechanical separation comprising a housing ( 4 ) and a conducting rail ( 2 ) which is arranged therein and embodied in such a way that it is separable at a separation point ( 13 ) by a separating tool ( 6 ) which is actuated by a propulsion pyrotechnical charge ( 12 ). In order to protect said conducting rail against manipulations and ensure an unequivocal positioning, the conducting rail ( 2 ), the propulsion charge ( 12 ) and the separating tool ( 6 ) are fixed in the housing ( 4 ) in an irremovable manner by a latch ( 5 ) which is inserted into the housing ( 4 ) and are nondetachably fixed thereto. Said latch ( 5 ) is also used as a support for the separating tool ( 6 ), i.e. it comprises a cutting edge ( 7 ) along which said separating tool ( 7 ) cuts.

Claims (8)

1. In a pyromechanical separating device comprising a housing, an electrical conductor rail arranged within the housing and having a separating point, a separating tool within the housing, and a pyrotechnic propellant charge adapted to drive the separating tool toward the separating point, the improvement comprising:

a latch non-releasably connected to the housing and fixing the conductor rail, the propellant charge and the separating tool within the housing, said latch forming a counter-bearing for the separating tool and including a cutting edge cooperating with the separating tool for cutting the separating point, and

wherein the housing includes a guide rib, and the conductor rail includes a recess receiving said guide rib.

2. The pyromechanical separating device according to claim 1 , wherein the latch includes chamfers arranged above and below the cutting edge.

3. The pyromechanical separating device according to claim 1 , wherein the latch is firmly connected to the housing by welding.

4. The pyromechanical separating device according to claim 1 , wherein the latch is firmly connected to the housing by a non-releasable snap-in connection.

5. The pyromechanical separating device according to claim 1 , wherein the housing further comprises a groove, and the latch further comprises a tongue received in said groove.

6. The pyromechanical separating device according to claim 1 , wherein the pyromechanical separating device is adapted for uncoupling a car battery in the event of an accident.
