Definitions
- the field of the present invention is that of pyrotechnic initiators, that is to say components making it possible to transmit a pyrotechnic effect in a pyrotechnic chain.
- pyrotechnic initiators that is to say components making it possible to transmit a pyrotechnic effect in a pyrotechnic chain.
- patents US2968985, US2767655 and US4819560 initiators whose housing is made of plastic.
- These inexpensive initiators are more particularly intended for initiating explosive cartridges used in the mining or quarrying industry. They generally include a plastic case of constant thickness which contains the initiation charge and which is fragmented during the initiation of the latter.
- the invention thus aims to provide an initiator which is both extremely reliable and robust, while being very resistant to electrostatic discharges.
- the invention finally proposes an initiator having a very high level of security, capable of initiating primary explosives, but also making it possible to use insensitive pyrotechnic compositions.
- the subject of the invention is a pyrotechnic initiator comprising a pyrotechnic substance placed inside a housing, and characterized in that that the housing comprises a metal wall secured to a bottom also metallic, the bottom being traversed by at least two electrodes of which at least one is electrically insulated from the bottom by an insulating material, and in that the housing comprises an overmolding in a material plastic surrounding at least the bottom and part of the electrodes.
- the housing is closed by a spangle on which the edge of the metal wall is folded.
- a seal will then be placed between the straw and the closing edge of the wall.
- the overmolding also surrounds the metal wall and carries a plastic plug which closes the housing.
- the bottom may carry a pellet of an insulating substrate on which will be deposited a semiconductor bridge partially covered by two conductive pads.
- one of the conductive pads is connected to the metal bottom of the housing via a semiconductor well passing through the substrate, said bottom being itself connected to one of the electrodes.
- a layer of thermal and electrical insulating material is deposited on the semiconductor bridge and isolates it from the pyrotechnic substance.
- the insulating material will preferably consist of silicon oxide or nitride deposited in a thin layer of between 0.5 and 10 micrometers.
- the pyrotechnic substance is deposited in the housing by a wet loading process.
- FIG. 1 represents in longitudinal section an initiator according to a first embodiment of 1 'invention
- FIG. 2 represents in longitudinal section an initiator according to a second embodiment of the invention
- FIG. 3 is an enlarged view of the initiation means used in this latter embodiment.
- an initiator 1 comprises a pyrotechnic substance 2 of known type, (for example an explosive (detonator) or an inflammatory pyrotechnic composition), substance placed in a housing 3.
- a pyrotechnic substance 2 of known type for example an explosive (detonator) or an inflammatory pyrotechnic composition
- the housing 3 includes a wall.
- metallic 4 cylindrical secured to a bottom 5 also metallic.
- Wall and bottom are made of stainless steel.
- the bottom here takes the form of a cap, the upper face 6 of which receives the pyrotechnic substance 2 and which has an enlarged collar 7 on which the wall 4 abuts. Bottom and wall are connected to each other by welding electric, laser welding or another type of welding.
- the bottom 5 is crossed by two electrodes 8a, 8b, one of which (8a) is in electrical contact with the bottom 5 and the other (8b) is electrically insulated therefrom by means of an insulating material 15 such as a glass filling. .
- a means for initiating the pyrotechnic substance is fixed between the electrodes.
- This means is here a resistive wire 9 which connects the electrodes 8a and 8b and which is fixed by welding on their ends.
- the electrical characteristics of the wire 9 are conventionally determined by a person skilled in the art as a function of the pyrotechnic characteristics of the substance 2.
- the housing 3 finally comprises an overmolding 10 of a plastic material which surrounds the bottom 5 and a part of the electrodes 8a, 8b.
- the rigidity of the connection is improved by the presence of the flange 7.
- This overmolding makes it possible to improve the mechanical resistance of the component, in particular with respect to impacts. It also completes the electrical insulation of the electrodes and protects the glass filling 15.
- the overmolding 10 is made of plastic material of the polyamide or polycarbonate type, a material possibly loaded with glass fibers to increase its mechanical strength.
- a load of 10% to 40% by mass of short glass fibers (a few tenths of a millimeter long) will be adopted.
- the overmolding 10 includes a bulge 11 which gives a bearing surface allowing for example its installation in a housing arranged in a pyrotechnic substance or in an initiation device not shown (housing to the diameter of the housing).
- the wall 4 of the housing is closed by a straw 12 on which the edge 13 of the metal wall is folded.
- An O-ring seal 14 is disposed between the straw 12 and the edge 13 for closing the wall.
- the pyrotechnic substance 2 is deposited inside the casing 3, preferably by a wet loading process, but it could also be put in place by compression.
- the initiator according to the invention can be manufactured easily and at low cost, the manufacture requiring only a few operations and each operation being simple and easily automated.
- the base carrying the electrodes and the insulating material constitutes a sub-assembly which is produced in standard manner in large quantities in the electronic industry for the manufacture of components such as transistors or thyristors. Such a component is very inexpensive.
- the plastic overmolding also makes it possible to obtain the shape which ensures the possibility of mounting the component in the desired application.
- Such overmolding is inexpensive.
- the filament is welded to the electrodes by means of welding techniques adapted to the wiring of integrated circuits, inexpensive techniques and allowing high production rates.
- the substance is placed by compression directly in the housing of the housing and on the filament.
- the metal wall and bottom also provide the initiator with excellent mechanical rigidity and, by forming a Faraday cage, give the initiator significant resistance to electrostatic discharge while protecting it from currents induced by the electromagnetic environment. .
- resistive wire 9 As a variant, it would be possible to replace the resistive wire 9 with a semiconductor, printed circuit or integrated circuit wafer, which can itself be glued to the bottom 5.
- the pyrotechnic substance 2 is preferably deposited according to the known method of wet loading.
- the substance is for example a quaternary substance of known type and combining in conventional proportions not specified here and which are well known to those skilled in the art:
- -a primary explosive such as lead tricinate
- -an oxidant such as potassium perchlorate
- Potassium Chlorate or Potassium Nitrate
- -a reducing agent such as antimony sulfide, Calcium silicide, graphite or aluminum powder
- an additive intended to increase or decrease the power of the initiator (such as lead thyocyanate, aluminum powder or lead dioxide).
- This substance will be mixed with 1 to 5% by mass of a binder such as natural gum or a synthetic binder and with water (5 to 30% by mass).
- a binder such as natural gum or a synthetic binder
- water 5 to 30% by mass.
- FIG. 2 represents another embodiment of the invention in which the bottom 5 has the form of a plate carrying a peripheral flange 7 on which the metal wall 4 is positioned.
- Wall and bottom are also made of stainless steel and are welded by electric arc.
- the electrode 8b is welded into a blind hole in the bottom 5 while the electrode 8a passes through the bottom. It is electrically isolated from the bottom by a glass ring 15.
- the plastic overmolding 10 surrounds the bottom, part of the electrodes and also the metal wall 4 over substantially its entire height.
- the rigidity of the joining is improved by the presence of the collar 7.
- the housing 3 is closed by a plug 16 made of the same plastic as that of the overmolding 10.
- the plug 16 has a cylindrical central part 17, of the same diameter as the metal wall 4, and whose 'front face 18 is in abutment on the pyrotechnic substance 2.
- the periphery of the plug 16 has a conical profile 16a which comes into contact with a complementary profile provided on the overmolding 10.
- the conical profile 16a is separated from the central part 17 by an annular groove 19.
- This clearance allows slight compression of the pyrotechnic substance during assembly, for example by ultrasonic welding.
- the plug is welded after evaporation of the water as described above.
- the ultrasonic welding is carried out in a known manner by applying a sonotrode of a welding device on a circular ring of the outer flat face of the plug, ring located substantially in line with the conical profile 16a (mark S).
- the vibrations of the sonotrode cause the contact surfaces, that is to say conical surfaces, to be welded.
- the plug 16 also includes a blind hole 20, produced on its external face, and which thus forms on the plug an area of reduced thickness or partition 21.
- the pressure generated by the pyrotechnic substance 2 breaks the zone of reduced thickness 21 and the initiator then transmits a pyrotechnic effect in an axial direction.
- the advantage of this latter embodiment is that it makes it possible to obtain a completely sealed initiator.
- the presence of the wall and the metal bottom also provide protection against electromagnetic influences and static electricity.
- Figure 3 is a partial and enlarged representation of the initiation means used in this second embodiment.
- the initiation means consists of a patch 22 of an insulating substrate based on undoped silicon, on which is deposited a semiconductor bridge 23
- conductive pads 24a and 24b (for example made of aluminum).
- the spacing between the pads is between 60 and 100 micrometers and preferably of the order of 80 micrometers.
- the characteristics of the initiator will be determined in a known manner by modifying the spacing of the pads, the dimensions of the semiconductor bridge and its doping.
- the stud 24a is connected to the electrode 8a by a connecting wire 25 fixed by welding.
- the stud 24b is connected to the electrode 8b via the metal bottom 5 through a semiconductor well 26 (doped silicon) which passes through the insulating substrate.
- a semiconductor well 26 doped silicon
- Such an arrangement makes it possible to reduce the risk of breakage of the connection wires (one wire used instead of two) during the loading operations with pyrotechnic substance.
- the technologies used to produce the wafer 22 are well known to those skilled in the art in the field of manufacturing electronic semiconductor components (doping of silicon, vacuum metallization, solders). These techniques are suitable for producing components in large series and therefore inexpensive.
- a composition will be adopted as the pyrotechnic substance, the average particle size of which is of the same order of magnitude as the dimensions of the semiconductor bridge.
- Such an arrangement makes it possible to limit the heat transfer at low temperature while ensuring this transfer by convection and / or projection at high temperature, which accentuates the effect of inherent non-linearity of the semiconductor (i.e. the precision of the threshold operating, therefore safety).
- a composition with an average particle size of 80 micrometers will be chosen (ie an actual particle size between 10 and 200 micrometers) for a bridge with a width of 80 micrometers.
- Such an initiation means also makes it possible to obtain a high concentration of energy over an area (the semiconductor bridge) of reduced surface.
- This technology thus allows the use of less sensitive pyrotechnic substances, for example boron-based compositions (20% by mass) and potassium nitrate (80% by mass) or aluminum compositions.
- the pyrotechnic substance will preferably be wet loaded in accordance with the process described previously. This type of charge ensures the reproducibility of the contact between the semiconductor bridge and the substance and also makes it possible to obtain with precision the desired mass of pyrotechnic substance. Alternatively, it is also possible to place in the housing a dry pyrotechnic substance.
- the plug 12 will, as previously, be kept in abutment against the pyrotechnic substance when it is fixed by welding to the skirt.
- thermal and electrical insulating material on the semiconductor bridge.
- This layer could for example be a layer of 0.5 to 10 micrometers thick of silicon oxide or silicon nitride.
- Such an insulating layer makes it possible to greatly reduce the heat transfer between the semiconductor bridge and the pyrotechnic substance. The latter cannot therefore be initiated or degraded when a low current flows (of the order of 0.3 amperes).
- the insulating layer is crossed by projections of silicon plasma at high pressure and high temperature and it can initiate explosives or insensitive pyrotechnic substances (for example a composition combining Boron and potassium nitrate).
- a chip 22 comprising logic circuits which control integrated switches (based on transistors or thyristors) which can block the flow of current in the semiconductor bridge 23.
- the initiator can then only be initiated in response to a specific coded signal transmitted superimposed on the power signal supplied by the electrodes (or transmitted by specific complementary electrodes crossing the bottom 5).
