Embodiment Construction

[0032] figure 1 Two webs 2 , 4 formed as planar parts are shown. The connecting pieces 2, 4 are at a distance from each other so that a connecting part 6, in the case of the figure soft solder, can be arranged in the gap 18 between the connecting pieces 2, 4. The connecting part 6 connects the connecting pieces 2, 4 both electrically and mechanically.

[0033] It can be seen that the webs 2 , 4 close the ballistic path 8 of the housing 14 of the ignition device 10 .

[0034] The housing 14 here is made of plastic and the housing walls are strong enough to withstand the gas pressure of the activated igniter 10 . It can be seen that the kindling 10 can be ignited by the electronic ignition wire. The ignition pulses can be received, for example, by an airbag control unit.

[0035] The connecting pieces 2 , 4 are bonded to the casing 14 in such a way that the ballistic 8 is sealed such that the gas pressure generated when the ignition charge 10 is triggered is sufficient to se...

Abstract

A current interrupter for motor-vehicle power lines having a first flat connecting lug, a second connecting lug and a connection part which electrically connects the connecting lugs and forms a weak point. Particularly simple production with little use of material can be achieved by the connecting lugs and the electrical connection part closing an explosion chamber of a pyrotechnic fuze such that the gas pressure which acts on initiation of the pyrotechnic fuze bursts the weak point.

Description

technical field [0001] The invention relates to a current circuit breaker for a vehicle power line, in particular comprising a connecting piece [0002] Formed connection parts that can be disconnected by pyrotechnics. Background technique [0003] Pyrotechnic insurance is well known in the field of automotive technology. An electronic safety switch which can be activated pyrotechnically is known, inter alia, from European patent application EP 0 665 556 A1. The safety switch is actuated in such a way that the propellant acts on a movable contact part which, by its movement, is carried away from the other contact part, thereby breaking the electrical path. In this method, there is always a piston driven in the sheath. The piston is driven by a pyrotechnic propellant in the sheath. Said safety switch is expensive to produce and is therefore expensive to manufacture. [0004] An electronic safety switch is likewise known from the German utility model DE 203 17 189 U1, whi...
