Definitions

  • the present invention relates to an electropyrotechnic igniter of flexible plastic technology which has enhanced functionalities compared to the state of the art. It has applications in various areas: Automotive Safety (airbag systems of all types, seatbelt tensioners and, more recently, under hood applications such as fire safety systems by battery cutter, protection of safety devices). pedestrians with pyrotechnic hood lifter etc ....), mines, quarries, public works, seismic, spatial and military initiation, fireworks etc ....
  • Electro-pyrotechnic igniters are subject to new and increasing requirements concerning, in particular, mechanical strength, thermal stability, fire resistance or, more generally, resistance to very high temperatures and electrostatic immunity.
  • the proposed lighter allows the respect of these requirements while allowing a modularity of the proposed solution.
  • the invention relates to an electropyrotechnic igniter as characterized by claim 1.
  • the electro-pyrotechnic igniter of proposed plastic technology is capable of filling in its entirety either a gas generator ignition function, and this without resorting to an intermediate device of "booster" type, that is a function such as those traditionally required for the pyromechanisms (setting in motion in translation, in rotation or other, of mechanical parts, drilling of metal wall, unlocking of security system, ).
  • boost a function such as those traditionally required for the pyromechanisms (setting in motion in translation, in rotation or other, of mechanical parts, drilling of metal wall, unlocking of security system, ).
  • the lighter of the proposed invention comprises two main subsets.
  • the first subassembly comprises a plastic wall integral with a bottom also made of plastic and forming a container for a pyrotechnic charge comprising at least one composition, said composition (s) being implemented either in bulk or in the form of pellets.
  • the pyrotechnic charge disposed in this first subset can also perform a self-initiation function.
  • this first subassembly may include a metal hoop providing, in addition to a mechanical reinforcement, an effective solution for controlling a directional effect along one or more preferred directions (axial or radial ignition, for example).
  • the second plastic subassembly has a main axis and is traversed by at least two pins or pins in the direction of said axis, said pads being interconnected by an electrical bridge on a face of said subassembly.
  • this second subassembly comprises on its first face a plastic ring for putting the electrothermal bridge vis-à-vis with the primary composition used in said igniter.
  • this second subassembly comprises a second ring whose function is to ensure the retention (including locking) of the electrical connector used for the application capable of integrating the product object of the present invention.
  • the second subassembly may comprise on its outer face a recess adapted to allow the housing of a protection component against electrostatic discharges as commonly used.
  • the protection component can be integrated according to several embodiments: it can be arranged on an intermediate circuit adapted to be threaded directly on the pins of the subassembly, said circuit then being assembled by a standard method to the power supply pads. . It is also possible to envisage a direct connection between the protection component and the power supply pads. To facilitate this operation, if necessary - this may be the case especially if the overall dimensions of the protection component are not ideally suited to the dimensional and geometric interface of the pads - it is possible to adapt the shape (geometry ) and the dimensions of pads. In this context, the obtaining of said pads can be advantageously by a method of cutting and stamping from a metal strip.
  • a palliative solution proposed may then be to provide the protection against electrostatic discharge on a double-sided circuit but, then, the cost of obtaining said circuit is significantly encumber the price of the igniter.
  • the protection against electrostatic discharges is overmolded within a first core.
  • the advantage of this solution is mainly that the subset thus obtained is part of an identical interface (in geometry and dimensions) to that of a subset not provided with protection.
  • the second plastic subassembly completes the connector interface function without the need to resort to the constituent designated by the name of shunt ring ("shorting clip” or "retainer”).
  • the shunt rings have the main function of short-circuiting the current supply lugs of the igniter to avoid any risk of creating a potential difference between said pads.
  • This short-circuiting is provided by flexible metal strips that retract when the connector is docked on the power supply pads. Due to the high level of electrostatic immunity demonstrated with the present igniter, especially when provided with the aforementioned immunity reinforcement, the short-circuiting of the current supply pads is not justified.
  • the other function traditionally provided by the shunt ring is the retention of the connector ("retainer" acting as a socket, and the plug connector).
  • the two main subsets are not necessarily strictly constituted of the same plastic material which opens optimal prospects of association in relation to the expected primary functions for each of said subsets. It is thus possible to combine different materials for the two plastic subassemblies according to the functional, operational and interface specificities of each client application. So ; the plastic used to make the first and / or second main subassemblies is a PPS (polyphenylene sulfide), a PPA, the polyarylamide or any other plastic material favorable to obtaining one or more of the improvements indicated above. after.
  • PPS polyphenylene sulfide
  • PPA polyarylamide
  • the plastic constituting the igniter or one of its main subsets contains one or more adjuvants conferring various useful properties.
  • this improvement gives the pyrotechnic system in which the igniter is integrated a better behavior tests type fire or extreme temperatures. These tests, required by the Regulations, are intended to verify the absence of uncontrolled behavior of a pyrotechnic device subjected to an extreme temperature rise such as may occur in the case of fire in particular.
  • the behavior of igniters to this type of regulatory requirement is based in part on the ability of said igniter to conduct heat.
  • the igniter is, as the first link in the pyrotechnic chain, the component of the pyrotechnic systems which has the threshold of auto-initiation (threshold temperature reaction) lowest so that brought to activate the sooner when the complete pyrotechnic system is stressed in temperature.
  • plastic technology igniters are generally penalized by the fact that the plastic materials constituting them are generally poor thermal conductors.
  • a suitable adjuvant substantially improves the thermal conductivity of plastic igniters.
  • the thermal conductivity of the material alone is approximately 0.2 W / mK and that of the same material with the appropriate adjuvant of 1W / mK, which makes it possible to multiply by a factor of 5 the level of thermal conductivity of the plastic material.
  • the appropriate adjuvant may be a metal filler (metal balls) or, more generally, any filler (mineral, ceramic, etc.) capable of improving the thermal conductivity.
  • thermomechanical stability besides its contribution also to the previously mentioned fire safety function, the improvement of thermomechanical stability properties considerably widens the scope of applications open to plastic technology igniters. It is thus possible to integrate plastic igniters in high power generating devices (typically devices generating pressures greater than 2000 bar).
  • high power generating devices typically devices generating pressures greater than 2000 bar.
  • the following table compares the results obtained on test pieces of different plastic materials and illustrates, from the point of view of toughness and thermal stability, the advantageous nature of materials such as PPS, PPA and PA6. -12 for igniters. The values given are rounded.
  • Adjuvants also allow properties of increased thermo-dimensional stability: this improvement makes it possible to consider new possibilities for implementing the pyrotechnic compositions.
  • igniters whose compositions are implemented by compression, it is indeed important to put the pyrotechnic charge in close contact with the thermal bridge of the igniter, the function of said bridge being to transmit to the composition of initiation a sufficient amount of heat for triggering the pyrotechnic reaction.
  • This indispensable condition of intimacy obliges to design the plastic subassemblies with tolerances of tight dimensions. The same applies to the adjustment of the pyrotechnic charge (control of its height as well as its pre-compression ratio) and control of assembly conditions.
  • thermo-dimensional stability is thus advantageous, firstly for plastic technology igniters insofar as it allows a widening of the construction tolerances of the parts constituting it on the one hand, as well as possibilities of implementing explosive compositions that are less restrictive in terms of dimensional control and compactness.
  • materials such as PPS and PPA whose longitudinal and transverse thermal expansion coefficients are given in the table below: Material Coefficient of longitudinal thermal expansion (ppm / ° C) Coefficient of transverse thermal expansion (ppm / ° C) PPP reinforcement 40% FV 20 60 PPS reinforcement 40% FV 25 45
