Definitions
- the resistive layer then advantageously has a rectangular surface, for example square. A precise determination of the resistance of the component and of a current intensity capable of triggering the initiator is thus obtained.
- Figure 3 shows an assembly of the inert and pyrotechnic sub-assemblies of Figures 1 and 2 respectively, constituting the initiator described by way of example.
- the inert sub-assembly 18, shown in Figure 1 has two electrical pins 7 intended to be connected to an electrical circuit. These two metal pins 7 for supplying current are typically made of iron-nickel FN50. Their diameter is for example 1 mm. Pins 7 are hermetically sealed in an insulating base electrically. This is preferably made of glass, but can also be made of ceramic or plastic, for example. A cylindrical body 9 surrounds this base 8 to which it is hermetically linked. This metallic body 9 is preferably made of stainless steel. The base 8 is coated with a cap 10 fitted onto the pins 7. This cap 10 is made of an electrically insulating material, and is preferably made of plastic. It is typically a polyamide. The cap 10 electrically isolates the metallic body 9 from the pyrotechnic part.
- the intensities 10 and II can be easily adjusted by playing on the surface S: the smaller the latter, the lower the values 10 and II.
- a semiconductor bridge 23 is particularly advantageous, because it allows very high precision in triggering the initiator 1. In fact, it only becomes resistive from a fixed voltage level. When this level is reached, a cascade phenomenon occurs, starting with a heating of the bridge 23 going hand in hand with a reduction in its resistance and ending with the discharge of a plasma in the composition 4. A minimum duration of application current is required to ignite.
