Abstract
Description
La présente invention concerne un initiateur électropyrotechnique.The present invention relates to an initiator An electro.
Il existe deux grandes catégories d'initiateur. La première fait appel à des embases de type "traversée verre-métal" et la seconde à des initiateurs à embase ou traversée de type "plastique". Les initiateurs appartenant à la première catégorie sont souvent regardés comme étant synonymes d'assurance d'herméticité et de protection infaillible des compositions pyrotechniques et/ou des explosifs contre les effets des environnements extrêmes (humidité entre autres). Or il est connu que les traversées de type verre-métal sont sensibles aux contraintes mécaniques et thermiques qui peuvent leur être appliquées au cours des différentes étapes de leur processus d'assemblage ou encore lors des étapes de montage (sertissage, soudage,...) desdits initiateurs à un dispositif d'applications pyrotechniques civiles (par exemple, prétensionneurs, coussins gonflables pour la sécurité automobile), militaires ou spatiales.There are two main categories of initiator. The first uses "glass-to-metal crossing" type bases and the second to initiators with base or crossing type "plastic". The initiators belonging to the first category are often seen as synonymous with insurance hermeticity and infallible protection of the compositions pyrotechnics and / or explosives against the effects of extreme environments (humidity among others). But, he is known that glass-to-metal crossings are sensitive to mechanical and thermal stresses that can be applied during the different stages of their process assembly or during the assembly stages (crimping, welding, ...) said initiators to an application device civil pyrotechnics (for example, pretensioners, cushions inflatable for automotive safety), military or space.
Par ailleurs si le recours à une embase de "traversée verre-métal" garantit a priori l'assurance d'une barrière hermétique de l'embase le long des broches d'amenée de courant, cela n'est pas forcément vrai pour la liaison entre l'embase et le contenant pyrotechnique.Moreover, if the use of a "crossing" glass-metal "guarantees a guarantee of a barrier hermetic of the base along the feed pins of This is not necessarily true for the link between the base and the pyrotechnic container.
Les initiateurs sur traversée plastique souffrent pour leur part d'un problème d'herméticité lié au matériau plastique (par exemple, polyamide sensible à l'humidité) retenu pour leur réalisation ou à leurs jointures internes (par clipsage, collage..) non étanches.The initiators on plastic traverse suffer for their of a hermeticity problem related to the plastic material (for example, moisture-sensitive polyamide) selected for their realization or at their internal joints (by clipping, gluing ..) not waterproof.
Enfin, les initiateurs actuels qu'ils appartiennent à l'une quelconque des catégories susmentionnées comprennent généralement plusieurs sous-ensembles à assembler rendant le coût total d'un tel dispositif onéreux. Les initiateurs de la première catégorie sont significativement les plus chers du fait de la préparation nécessaire (surfaçage,...) desdites traversées "verre-métal".Finally, the current initiators that they belong to one any of the above categories include usually several subassemblies to assemble making the total cost of such an expensive device. The initiators of the first category are significantly more expensive because the necessary preparation (surfacing, ...) of said crossings "Glass-metal".

L'initiateur électropyrotechnique, selon l'invention,
comporte un boítier 1. Ce boítier 1 comporte un premier 2 et
deuxième 3 sous-ensembles. Le premier sous-ensemble 2
comprend une paroi 4 en plastique solidaire d'un fond 5
également en plastique, le premier sous-ensemble 2 étant fait
d'une seule pièce. Ce premier sous ensemble 2 est appelé un
contenant. Ledit contenant 2 reçoit une charge pyrotechnique 6
par un procédé de chargement à sec. La charge 6 comprend au
moins une composition. Dans un mode de réalisation, le
contenant 2 reçoit une première composition 7 appelée
composition secondaire et une seconde composition 8 appelée
composition primaire. Chacune des compositions de la charge
pyrotechnique 6 est chargée en masse puis est précompressée.
Avantageusement, la précompression est réalisée avec une
pression inférieure à 120 bars pour la composition primaire 8
et avec une pression supérieure à 150 bars pour la composition
secondaire 7. L'effort de compression finale est assuré lors de
l'assemblage hermétique du premier sous-ensemble 2 avec un
deuxième sous-ensemble 3 comportant la partie électrique de
l'initiateur, ledit sous-ensemble 3 étant aussi appelée embase.
L'assemblage est réalisé par soudage ultrasons assurant une
extrême herméticité. On appelle ici - hauteur de vide - h' la
différence de hauteur entre la couche 9 la plus externe de la
charge pyrotechnique 6 après précompressage des compositions
et la face 15 du contenant 2. Avantageusement, les première 7
et deuxième 8 compositions sont exemptes de métaux lourds
dans un souci de respect de l'environnement. Lesdites
compositions sont également résistantes à l'échauffement
provoqué par la soudure ultrason qui est de l'ordre de 260°C.The electropyrotechnic initiator, according to the invention,
comprises a housing 1. This housing 1 comprises a first 2 and
second 3 subsets. The
Dans un mode de réalisation préféré, le diamètre intérieur
D1 du premier sous-ensemble 2 est inférieur à 5,6 mm.
L'adaptation du volume intérieur du contenant 2 afin de
permettre le chargement de compositions pyrotechniques de
différentes natures et granulométrie est donc assurée par la
variation de la hauteur dudit contenant 2. Le faible diamètre
intérieur du premier sous-ensemble 2 permet avantageusement
de ne pas avoir à recourir à un contenant pyrotechnique
intermédiaire tel que, par exemple, une bague rapportée sur
l'embase 3 pour limiter la charge pyrotechnique 6. Cette
limitation de la charge pyrotechnique 6 offre de plus une
sécurité accrue sans risque pour la fiabilité de fonctionnement
pyrotechnique dans la mesure où l'épaisseur de la composition
chargée est suffisante.In a preferred embodiment, the inner diameter D 1 of the
Le deuxième sous-ensemble 3, l'embase, en plastique a
un axe principal 10 et est traversé par au moins deux broches
11, 12 selon la direction dudit axe 10. Les broches 11, 12 sont
reliées entre elles par un pont électrique 13 sur une face 14
dudit sous-ensemble 3. Dans un mode de réalisation, le pont
électrique 13 est de type résistif. Avantageusement, il s'agit
soit d'un filament soit d'une couche métallique. Dans un autre
mode de réalisation, le pont électrique 13 est de type semiconducteur.
Ladite face 14 est évidée symétriquement sur une
hauteur H et une profondeur L de sorte que le diamètre externe
de la partie du deuxième sous-ensemble 3 ayant été évidée soit
D2. Avantageusement, la hauteur H est comprise entre 2 et 3
mm. Dans un mode de réalisation préféré, le diamètre intérieur
D1 du premier sous-ensemble 2 est inférieur au diamètre
externe D2. Ces parties des premier 2 et deuxième 3 sous-ensembles
étant mises en vis-à-vis lors du soudage ultrasons,
cette différence de diamètre entre D1 et D2 assure une
herméticité maximale et une rigidité diélectrique suffisante
pour l'isolation des parties internes conductrices 11, 12 de
l'initiateur. Avantageusement, le joint de soudure 16 est un
joint en cisaillement. La face évidée 14 du deuxième sous-ensemble
3 présente également un évidement 17 symétrique de
hauteur h et de largeur l pour former un ílot de surélévation du
pont électrique, ceci assurant une bonne intimité entre le pont
électrique 13 et la composition primaire 8. Avantageusement h
est comprise entre 0,5 et 1,0 mm et la largeur l est comprise
entre 0,2 et 0,8 mm. The
Le deuxième sous-ensemble 3 est surmoulé sur des
broches 11, 12. On appelle ici - broche - des moyens d'amenée
de courant pour l'initiateur. Dans un premier mode de
réalisation, les broches 11, 12 comprennent des électrodes.
Avantageusement, les électrodes sont striées. Ces stries 18
assurent non seulement une barrière hermétique de l'initiateur
le long des broches 11, 12 mais elles facilitent également la
fixation du matériau plastique lors du surmoulage. Dans un
deuxième mode de réalisation, les broches 11, 12 sont des fils.The
Le premier 2 et deuxième 3 sous-ensembles sont réalisés dans le même matériau plastique afin de permettre leur assemblage par soudage ultrasons. Le plastique utilisé pour réaliser le premier 2 et deuxième 3 sous-ensembles est un matériau à faible reprise d'humidité. Dans un premier mode de réalisation, le plastique est un polycétone. Dans un autre mode de réalisation, le plastique est un polybutylène teraphtalate (PBT). Dans un mode de réalisation préféré, le matériau plastique est un polyamide. A titre de polyamides utilisables selon l'invention, on peut citer les polyamides à faible reprise d'humidité, et en particulier le polyamide de formule : désigné dans la présente demande par PA 6.12.The first 2 and second 3 subassemblies are made of the same plastic material to allow their assembly by ultrasonic welding. The plastic used to make the first 2 and second 3 subassemblies is a material with low moisture absorption. In a first embodiment, the plastic is a polyketone. In another embodiment, the plastic is a polybutylene teraphthalate (PBT). In a preferred embodiment, the plastic material is a polyamide. As polyamides that may be used according to the invention, mention may be made of polyamides with low moisture uptake, and in particular the polyamide of formula: designated in this application by PA 6.12.
Les sous-ensembles 2, 3 de l'initiateur selon l'invention
ne sauraient être limités à la description qui précède et sont
susceptibles de modifications avec l'évolution des
technologies. Des substitutions et/ou des modifications dans la
structure générale et dans les détails du présent initiateur
peuvent être réalisées par un homme du métier sans s'écarter
de l'esprit de la présente invention. Ainsi, la figure 4 montre
un joint de soudure 16 ultrason qui ne comprend pas un joint
en cisaillement mais un joint en semi-cisaillement.
Le présent initiateur pyrotechnique peut avantageusement être utilisé pour la réalisation de dispositif d'applications pyrotechniques civiles, militaires et spatiales. Dans le cas où l'initiateur est en polycétone, il peut avantageusement être mis en contact ou placé à proximité de vapeurs ou liquides de produits chimiques.The present pyrotechnic initiator can advantageously be used for the realization of application device civil, military and space pyrotechnics. In the case where the initiator is in polyketone, it can advantageously be put in contact with or placed near vapors or liquids chemical products.
