Abstract

The fixture (6) has movable and fixed support plates attached respectively facing one another to cylindrical components. Three electrical connectors (11-13) are mounted parallel to one another and aligned in a circular arc (AC) with respect to a longitudinal axis on the plates. Two separable mechanical attachment systems (15) fixedly connect the plates by locking parts of the connectors. The attachment systems are positioned offset from the arc, on the inside of the arc, and lie, in projection perpendicular to the axis, in an isosceles triangular plane (P) formed by the aligned connectors.

Description

La présente invention concerne un montage à connexions électriques et systèmes de liaison mécanique séparable, destiné à maintenir assemblés deux composants cylindriques l'un par rapport à l'autre et à permettre, à la suite d'un ordre donné, leur séparation par un mouvement axial relatif entre les deux composants, initié par les systèmes de liaison.The present invention relates to a mounting with electrical connections and separable mechanical connection systems, intended to maintain assembled two cylindrical components relative to each other and to allow, following a given order, their separation by a movement relative axial between the two components, initiated by the connecting systems.

Un tel montage peut trouver des applications dans de nombreux domaines techniques dès l'instant où l'on souhaite procéder à la séparation de deux composants préalablement assemblés, à un moment précis, commandable.Such an assembly can find applications in many technical fields from the moment when it is desired to proceed to the separation of two previously assembled components, at a specific time, controllable.

Par exemple, dans une application préférentielle quoique non exclusive, le montage peut être implanté dans une munition incluant un vecteur, tel qu'un missile. En effet, on sait que certaines parties de la munition doivent être séparées les unes des autres lors de la mise à feu et durant la trajectoire du vol. Tel est notamment le cas entre le culot ou la partie inférieure de la munition et le système d'accélération et de basculement du missile liés notamment entre eux par un tel montage spécifique portant des connecteurs électriques et des systèmes de liaison mécanique séparable, et disposé dans un espace annulaire interne prévu entre le culot et le système d'accélération.For example, in a preferential application although not exclusive, the assembly can be implanted in an ammunition including a vector, such as a missile. Indeed, it is known that some parts of the ammunition must be separated from each other during firing and during the flight path. This is particularly the case between the base or the lower part of the munition and the missile acceleration and tilting system linked in particular to each other by such a specific assembly carrying electrical connectors and separable mechanical connection systems, and arranged in an inner annular space provided between the base and the acceleration system.

Les connecteurs électriques servent à établir la communication (transfert d'informations) entre le système d'accélération et de basculement du missile et l'installation de tir et doivent être, par conséquent, parfaitement connectés puis séparés par les systèmes de liaison mécanique selon les ordres transmis.The electrical connectors are used to establish the communication (transfer of information) between the missile acceleration and tilting system and the firing installation and must therefore be perfectly connected and separated by the mechanical link systems in accordance with orders transmitted.

Par exemple, un montage connu pour l'assemblage de deux composants cylindriques d'axe longitudinal commun, comporte usuellement :

  • deux platines de support rapportées respectivement en vis-à-vis l'une de l'autre sur les composants sensiblement en périphérie de ceux-ci ;
  • au moins trois connecteurs électriques en deux parties chacun, montés parallèlement entre eux et de façon alignée en arc de cercle par rapport audit axe longitudinal sur lesdites platines de support, chacune d'elles portant les parties correspondantes des connecteurs, et
  • entre les trois connecteurs électriques, parallèlement à ceux-ci, deux systèmes de liaison mécanique séparable reliant fixement lesdites platines de support en verrouillant lesdites parties des connecteurs.
For example, a known assembly for the assembly of two cylindrical components of common longitudinal axis, usually comprises:
  • two support plates reported respectively vis-à-vis one another on the components substantially peripherally thereof;
  • at least three electrical connectors in two parts each, mounted parallel to each other and aligned in an arc of a circle with respect to said longitudinal axis on said support plates, each carrying the corresponding parts of the connectors, and
  • between the three electrical connectors, parallel thereto, two separable mechanical connection systems fixedly connecting said support plates by locking said parts of the connectors.

Le regroupement des trois connecteurs électriques sur un même et unique montage, de surcroît alignés sur un arc de cercle commun avec les systèmes de liaison disposés symétriquement entre les connecteurs, sur ledit arc de cercle, conduit à occuper un encombrement minimal entre les composants, avec de plus un gain de poids appréciable et une moindre complexité de réalisation, comparativement à une conception avec trois montages distincts pour les connecteurs respectifs, répartis à 120° les uns des autres et munis alors de deux systèmes de liaison symétriquement disposés pour chaque connecteur électrique.The grouping of the three electrical connectors on one and the same assembly, furthermore aligned on a common circular arc with the connection systems disposed symmetrically between the connectors, on said arc of a circle, leads to occupy a minimal bulk between the components, with in addition a significant weight gain and less complexity of implementation, compared to a design with three separate assemblies for the respective connectors, distributed at 120 ° from each other and then provided with two symmetrically arranged connection systems for each electrical connector.

Bien que donnant des résultats satisfaisants, ce montage compact à trois connecteurs électriques et deux systèmes de liaison mécanique peut présenter certains inconvénients, en particulier, au moment de la mise en place des connexions électriques, lors du serrage des systèmes de liaison sur les platines de support sur lesquelles sont fixées les parties respectives des connecteurs et qui se rapprochent relativement l'une vers l'autre.Although giving satisfactory results, this compact assembly with three electrical connectors and two mechanical connection systems may present certain drawbacks, in particular at the time of the establishment of the electrical connections, during the tightening of the connection systems on the plates of support on which are fixed the respective parts of the connectors and which are relatively close to each other.

En effet, comme les deux connecteurs électriques d'extrémité identiques entre eux sont dimensionnellement plus grands que le connecteur électrique central, la raideur à vaincre pour assurer la connexion totale entre les deux parties de ces connecteurs d'extrémité est alors bien supérieure à celle du connecteur central. Cette raideur, déterminée par les fabricants de connecteurs en fonction de divers paramètres (courant, milieu, dimension, ...), est fournie par un élément ou tapis en caoutchouc ménagé entre les deux parties et qu'il convient de presser pour garantir l'étanchéité de la connexion électrique des connecteurs. Aussi, comme cette raideur est plus importante au niveau des connecteurs d'extrémité et que les systèmes de liaison sont sur le même arc de cercle que les connecteurs, lors de la mise en place du montage pendant le serrage des systèmes de liaison au moment d'écraser les éléments d'étanchéité, les efforts axiaux exercés par les systèmes tendent à faire basculer la platine de support mobile par rapport à l'autre platine, de sorte que le montage ainsi obtenu n'est pas parfaitement correcte, ce qui n'est pas souhaitable dans l'application concernée.Indeed, as the two end electrical connectors identical to each other are dimensionally larger than the central electrical connector, the stiffness to be overcome to ensure the total connection between the two parts of these end connectors is then much greater than that of the central connector. This stiffness, determined by the manufacturers of connectors according to various parameters (current, medium, dimension, ...), is provided by a rubber element or mat formed between the two parts and that it is necessary to press to guarantee the sealing of the electrical connection of the connectors. Also, as this stiffness is more important at the end connectors and that the connection systems are on the same circular arc as the connectors, when setting up the assembly during the tightening of the connection systems when crushing the sealing elements, the axial forces exerted by the systems tend to tilt the mobile support plate relative to the other plate, so that the assembly thus obtained is not perfectly correct, which is not desirable in the application concerned .

La présente invention a pour but de remédier à ces inconvénients.The present invention aims to overcome these disadvantages.

A cet effet, le montage à connexions électriques et systèmes de liaison mécanique séparable pour l'assemblage de deux composants cylindriques d'axe longitudinal commun, du type tel que défini précédemment, est remarquable, selon l'invention, en ce que les deux systèmes de liaison séparable sont placés de manière décalée dudit arc de cercle, du côté intérieur à celui-ci, et sont situés, en projection perpendiculaire audit axe longitudinal, dans le plan triangulaire formé par les trois connecteurs électriques alignés en arc de cercle.For this purpose, the assembly with electrical connections and separable mechanical connection systems for the assembly of two cylindrical components of common longitudinal axis, of the type as defined above, is remarkable, according to the invention, in that the two systems separable connection are placed offset from said arc of the inner side thereof, and are located in projection perpendicular to said longitudinal axis in the triangular plane formed by the three electrical connectors aligned in an arc.

Ainsi, grâce à l'invention, les efforts axiaux délivrés par les systèmes de liaison pour engager les parties des connecteurs et notamment vaincre la raideur des connecteurs d'extrémité et verrouiller le montage, passent perpendiculairement par le plan triangulaire délimité par les trois connecteurs, et non plus à l'extérieur de celui-ci, ce qui évite les risques de basculement de la platine de support mobile par rapport à la platine de support fixe.Thus, thanks to the invention, the axial forces delivered by the connecting systems to engage the parts of the connectors and in particular to overcome the stiffness of the end connectors and to lock the assembly, pass perpendicularly through the triangular plane delimited by the three connectors, and no longer outside of it, which avoids the risk of tilting of the movable support plate relative to the fixed support plate.

De préférence, le montage comprend de plus une butée axiale parallèle aux systèmes de liaison mécanique séparable et disposée entre les deux platines de support, pour former, avec les deux systèmes de liaison séparable, un plan parallèle au plan triangulaire formé par les trois connecteurs électriques. La distance entre ces deux plans est par ailleurs calibrée permettant d'assurer l'effort de compression approprié sur les éléments d'étanchéité prévus entre les parties des connecteurs, garantissant les connexions électriques.Preferably, the assembly further comprises an axial abutment parallel to the separable mechanical connection systems and disposed between the two support plates, to form, with the two separable connection systems, a plane parallel to the triangular plane formed by the three electrical connectors. . The distance between these two planes is also calibrated to ensure the appropriate compression force on the sealing elements provided between the parts of the connectors, ensuring the electrical connections.

Ainsi, on obtient une action plan contre plan des systèmes de liaison à butée axiale sur les platines de support sur lesquelles sont fixées les parties respectives des connecteurs électriques alignés en arc de cercle. Le risque de basculement est alors totalement supprimé.Thus, a plane-to-plane action of the axial abutment connection systems is obtained on the support plates on which the respective parts of the electrical connectors aligned in an arc of a circle are fixed. The risk of failover is then completely removed.

En particulier, ladite butée axiale est située en projection perpendiculaire audit axe longitudinal, devant le connecteur électrique central au-delà dudit arc de cercle, du côté extérieur à celui-ci. Et, dans un mode préféré de réalisation, ladite butée axiale se présente sous la forme d'une tige rapportée fixement par ses extrémités entre les deux platines de support. Par ailleurs, les deux systèmes de liaison sont de préférence rapprochés des deux connecteurs électriques d'extrémité.In particular, said axial abutment is located in projection perpendicular to said longitudinal axis, in front of the central electrical connector beyond said arc, on the outer side thereof. And, in a preferred embodiment, said axial abutment is in the form of a rod attached fixedly by its ends between the two support plates. Moreover, the two connecting systems are preferably close to the two electrical end connectors.

Dans un mode préféré de réalisation, chaque système de liaison mécanique séparable comporte un mécanisme de liaison desdits composants et un dispositif de commande dudit mécanisme de liaison pour entraîner la séparation desdits composants,

  • ledit mécanisme de liaison étant à déformation élastique et comprenant, selon un axe longitudinal, au moins :
    • une tige ayant une extrémité élargie à tête sphérique fendue longitudinalement et élastiquement déformable, et fixée, à son autre extrémité, à la platine de l'un desdits composants ;
    • une aiguille mobile axialement dont une extrémité est introduite dans ladite tête sphérique de la tige pour la maintenir en position ouverte et dont l'autre extrémité est reliée audit dispositif de commande ; et
    • un corps à trou axial, fixé à la platine de l'autre composant et entourant lesdites extrémités coopérantes de la tige et de l'aiguille, en étant lié axialement à cette dernière et comportant, dans ledit trou, une butée axiale annulaire contre laquelle s'applique ladite tête sphérique de la tige ; et
  • ledit dispositif de commande étant à déplacement axial, selon ledit axe longitudinal, et agissant sur ladite aiguille du mécanisme de liaison pour l'éloigner de ladite extrémité élargie à tête sphérique de la tige et, par l'action de ladite butée du corps lié à ladite aiguille déplacée, faire passer ladite tête sphérique élastiquement déformable de sa position ouverte à une position fermée et permettre le passage relatif de ladite tige à travers ladite butée du corps.
In a preferred embodiment, each separable mechanical connection system comprises a mechanism for connecting said components and a device for controlling said linking mechanism to cause the separation of said components,
  • said connecting mechanism being elastically deformable and comprising, along a longitudinal axis, at least:
    • a rod having an enlarged end with a spherical head slotted longitudinally and elastically deformable, and fixed at its other end to the plate of one of said components;
    • an axially movable needle, one end of which is inserted into said spherical head of the rod to keep it in the open position and the other end of which is connected to said control device; and
    • a body with an axial hole, fixed to the plate of the other component and surrounding said cooperating ends of the rod and the needle, being axially connected thereto and comprising, in said hole, an annular axial abutment against which applies said spherical head of the rod; and
  • said control device being axially displaced, along said longitudinal axis, and acting on said needle of the connecting mechanism to move it away from said enlarged spherical head end of the rod and, by the action of said body stop connected to said needle moved, passing said head spherical elastically deformable from its open position to a closed position and allow the relative passage of said rod through said abutment body.

Ainsi, on utilise la combinaison de l'élasticité de l'extrémité à tête sphérique élargie de la tige et du déplacement axial de l'aiguille mue par le dispositif de commande pour, d'une part, fixer les deux composants par les platines, et les connecteurs et, d'autre part, les séparer, avec un effort de séparation relativement faible, fonction de l'élasticité de l'extrémité élargie pour passer de sa position ouverte initiale à sa position fermée.Thus, the combination of the elasticity of the end with the enlarged spherical head of the rod and the axial displacement of the needle moved by the control device is used to fix the two components by the plates, and the connectors and, on the other hand, separate them, with a relatively small separation force, depending on the elasticity of the enlarged end to move from its initial open position to its closed position.

De préférence, la liaison de ladite aiguille audit dispositif de commande comporte un écrou de fixation recevant l'extrémité filetée de l'aiguille, opposée à celle introduite dans ladite tige, et une vis dudit dispositif, et il est prévu autour de ladite vis, entre ledit dispositif de commande et l'écrou de fixation, un ressort de compression forçant à maintenir axialement en position ladite aiguille dans la tête sphérique de la tige. Ainsi, en cas de mouvement vibratoire ou analogue, en plus des efforts de pincement de la tête sphérique fendue et élastique, le ressort empêche tout déverrouillage intempestif de l'aiguille de la tête sphérique.Preferably, the connection of said needle to said control device comprises a fixing nut receiving the threaded end of the needle, opposite to that inserted in said rod, and a screw of said device, and it is provided around said screw, between said control device and the fixing nut, a compression spring forcing to maintain axially in position said needle in the spherical head of the rod. Thus, in the event of vibratory movement or the like, in addition to the clamping forces of the split and elastic spherical head, the spring prevents any inadvertent unlocking of the needle of the spherical head.

En particulier, ladite tête sphérique comporte au moins deux fentes ménagées dans des plans longitudinaux perpendiculaires en séparant ladite tête sphérique en quatre quartiers identiques élastiquement déformables, au centre desquels peut s'introduire l'extrémité correspondante de ladite aiguille pour la maintenir en position initiale ouverte.In particular, said spherical head comprises at least two slots formed in perpendicular longitudinal planes by separating said spherical head into four elastically deformable identical quarters, in the center of which the corresponding end of said needle can be introduced to keep it in its initial open position. .

Et ladite butée du corps définit une portée annulaire sphérique complémentaire de la tête sphérique et est conformée en un élément annulaire monté autour de ladite tige et rapporté par vissage sur ledit corps.And said abutment of the body defines a complementary spherical annular bearing surface of the spherical head and is shaped into an annular element mounted around said rod and screwed onto said body.

La munition M représentée sur la figure 1 se compose usuellement de plusieurs parties (ou étages) cylindriques assemblées selon un axe longitudinal X, désignées ici culot ou partie arrière, basse 1, tube ou partie centrale 2 et coiffe ou partie avant, haute 3, à l'intérieur desquelles se trouve un composite C comprenant un missile 4 (système de guidage et charge militaire non illustrés) lié au système d'accélération et de basculement 5 et qui, lors de la mise à feu du composite et durant la trajectoire du vol, sont amenées à se séparer.The ammunition M shown on the figure 1 usually consists of several cylindrical parts (or stages) assembled along a longitudinal axis X, here referred to as a base or a rear part, low 1, tube or central part 2 and a cap or front part, high 3, inside which there is a Composite C comprising a missile 4 (guide system and military load not shown) related to the acceleration and tilt system 5 and which, during the ignition of the composite and during the flight path, are caused to separate.

Pour cela, dans la réalisation illustrée et agrandie de la figure 2, l'assemblage entre le culot 1 et le système d'accélération et de basculement 5 du composite C est obtenu, en plus de verrouillages périphériques par emboîtement ou analogue non représentés ici, par un montage spécifique 6 assurant la connexion électrique entre le système 5 du composite et le culot 1, et la liaison mécanique entre ceux-ci, confirmant de plus la connexion électrique.For this, in the illustrated and enlarged realization of the figure 2 , the assembly between the base 1 and the accelerating and tilting system 5 of the composite C is obtained, in addition to interlocking device interlockings or the like not shown here, by a specific assembly 6 providing the electrical connection between the system 5 composite and the base 1, and the mechanical connection between them, further confirming the electrical connection.

Dans la réalisation illustrée et de façon usuelle, le montage 6 est situé dans l'espace annulaire interne disponible 7 proche de la périphérie de la munition, entre le culot 1, le système d'accélération 5 et le tube 2. Il comporte deux platines ou plaques parallèles, l'une inférieure 8 fixée au culot par des tirants 10 et l'autre supérieure 9, désignée support de flottement (du fait de sa liaison au missile) et reliée au système d'accélération 5, trois connecteurs électriques 11, 12, 13 établissant la communication électrique entre la partie basse 1 de la munition, reliée à l'installation de tir, et le système d'accélération 5 relié au missile, et deux systèmes de liaison mécanique séparable identiques 15 maintenant les deux platines entre elles et la connexion électrique entre les connecteurs, jusqu'au moment où, l'ordre de tir étant donné, ils assurent la séparation des platines et, donc, celle du système d'accélération 5 d'avec le culot 1.In the embodiment illustrated and in the usual way, the assembly 6 is located in the available internal annular space 7 close to the periphery of the munition, between the base 1, the acceleration system 5 and the tube 2. It comprises two plates or parallel plates, one lower 8 fixed to the base by tie rods 10 and the other upper 9, designated floating support (because of its connection to the missile) and connected to the acceleration system 5, three electrical connectors 11, 12, 13 establishing the electrical communication between the lower part 1 of the ammunition, connected to the firing installation, and the acceleration system 5 connected to the missile, and two identical separable mechanical connection systems 15 holding the two decks between them and the electrical connection between the connectors, until, given the firing order, they ensure the separation of the plates and, therefore, that of the acceleration system 5 from the base 1.

En particulier, comme le montrent les figures 2, 3 et 6, les trois connecteurs électriques 11, 12, 13 sont parallèles entre eux et à l'axe longitudinal X pour leur connexion/déconnexion, et sont placés en plan (perpendiculairement à l'axe X) selon un même rayon R, c'est-à-dire qu'ils sont alignés selon un même arc de cercle AC (figures 2 et 3) dans l'espace annulaire interne 7. On remarque que les connecteurs d'extrémité 11, 13 sont identiques et dimensionnellement plus grands que le connecteur central 12, comme on l'a vu précédemment, et qu'ils sont situés à égale distance du connecteur central. Et structurellement, les trois connecteurs sont constitués d'une partie inférieure à embase 11A, 12A, 13A rapportée fixement à la platine inférieure 8, et d'une partie supérieure à fiche 11 B, 12B, 13B, rapportée fixement au support de flottement ou platine supérieure 9 (figures 2 et 6). L'étanchéité entre ces parties est obtenue par un élément en caoutchouc symbolisé en 11C, 12C, 13C sur la figure 6. Les liaisons électriques de ces parties aux alimentations et différents équipements n'ont pas été représentées.In particular, as shown by the figures 2 , 3 and 6 the three electrical connectors 11, 12, 13 are parallel to each other and to the longitudinal axis X for their connection / disconnection, and are placed in a plane (perpendicular to the X axis) along the same radius R, that is, to say that they are aligned according to the same arc of circle AC ( figures 2 and 3 ) in the inner annular space 7. Note that the end connectors 11, 13 are identical and dimensionally larger than the central connector 12, as previously seen, and they are located equidistant from the central connector. And structurally, the three connectors consist of a base bottom portion 11A, 12A, 13A fixedly attached to the bottom plate 8, and an upper plug portion 11B, 12B, 13B, fixedly attached to the floating support or upper platen 9 ( figures 2 and 6 ). The seal between these parts is obtained by a rubber element symbolized at 11C, 12C, 13C on the figure 6 . The electrical connections of these parts to power supplies and various equipment were not represented.

Aussi, pour éviter les problèmes rencontrés et énoncés préalablement, les deux systèmes de liaison séparable 15 sont décalés de l'arc de cercle AC sur lequel ils se trouvaient initialement alignés avec les trois connecteurs, pour être situés du côté intérieur à l'arc de cercle AC vers l'axe longitudinal X. Ainsi, les systèmes sont placés dans le plan triangulaire P formé par les trois connecteurs électriques 11, 12, 13 et sont rapprochés des connecteurs d'extrémité. On voit, sur la figure 3, le plan triangulaire isocèle P obtenu en joignant les axes géométriques XC des connecteurs, avec les axes XS des deux systèmes de liaison séparable 15 qui se trouvent dans le plan triangulaire P respectivement symétriquement de part et d'autre de l'axe de symétrie S de ce triangle isocèle.Also, to avoid the problems encountered and stated beforehand, the two separable connection systems 15 are offset from the arc of circle AC on which they were initially aligned with the three connectors, to be located on the inner side to the arc of circle AC to the longitudinal axis X. Thus, the systems are placed in the triangular plane P formed by the three electrical connectors 11, 12, 13 and are close to the end connectors. We see, on the figure 3 , the isosceles triangular plane P obtained by joining the geometric axes XC of the connectors, with the XS axes of the two separable connection systems 15 which are in the triangular plane P respectively symmetrically on either side of the axis of symmetry S of this isosceles triangle.

Et, une butée 16 sous la forme d'une tige rigide ou analogue 17 est placée entre les deux platines supérieure 9 et inférieure 8, parallèlement aux axes XC des connecteurs et X de la munition, et située à l'extérieur de l'arc de cercle AC au droit de l'axe XC du connecteur central 12. Ainsi, en projection dans le plan P des connecteurs représentés sur la figure 3, la tige 17 de la butée 16 forme avec les axes XS des deux systèmes de liaison séparable 15, un plan triangulaire isocèle P1 parallèle au plan P formé par les trois connecteurs 11, 12, 13. On obtient ainsi, lors de la mise en place des connecteurs et des systèmes de liaison, une action plan P (connecteurs) contre plan P1 (systèmes de liaison et butée). De la sorte, lors du serrage des systèmes 15 du montage 6, tout basculement de la platine ou support de flottement 9 est évité même avec des raideurs importantes à vaincre, fournis par les éléments d'étanchéité 11C et 13C représentés sur la figure 6 au niveau de la connexion embase-fiche des parties correspondantes 11A-11 B, 13A-13B des connecteurs d'extrémité.And, a stop 16 in the form of a rigid rod or the like 17 is placed between the two upper plates 9 and lower 8, parallel to the XC axes of the connectors and X of the munition, and located outside the arc of circle AC to the axis XC of the central connector 12. Thus, in projection in the plane P of the connectors represented on the figure 3 , the rod 17 of the abutment 16 forms with the XS axes of the two separable connection systems 15, an isosceles triangular plane P1 parallel to the plane P formed by the three connectors 11, 12, 13. This is how, when the place connectors and connection systems, a plane action P (connectors) against plane P1 (connection and stop systems). In this way, when tightening the systems 15 of the assembly 6, any tilting of the plate or floating support 9 is avoided even with significant stiffness to overcome, provided by the sealing elements 11C and 13C shown on the drawing. figure 6 at the base-plug connection of the corresponding parts 11A-11B, 13A-13B of the end connectors.

On voit, sur la figure 4, le basculement du support de flottement 9, représenté de façon exagérée en trait pointillé, qui se produit lorsque les deux systèmes de liaison séparable 15 sont situés, selon l'art antérieur, sur l'arc de cercle AC des connecteurs. En revanche, avec un agencement plan contre plan et les systèmes de liaison 15 du côté intérieur à l'arc de cercle AC, le risque de basculement du support de flottement 9 et d'une mauvaise mise en place du montage 6 sont supprimés, les deux platines supérieure 9 et inférieure 8 portant les connecteurs et les systèmes de liaison, restant parallèles, lors de l'assemblage du montage.We see, on the figure 4 , the tilting of the floating support 9, shown in an exaggerated dotted line, which occurs when the two separable connection systems 15 are located, according to the prior art, on the arc AC of the connectors. On the other hand, with a plane-to-plane arrangement and the connection systems 15 on the inside of the arc of the circle AC, the risk of tilting of the floating support 9 and of improper installation of the assembly 6 are eliminated, the two upper and lower plates 9 9 carrying connectors and connection systems, remaining parallel, during assembly assembly.

En ce qui concerne les systèmes de liaison mécanique séparable 15, un mode préféré de réalisation est représenté sur les figures 5, 5A et 6.With regard to the separable mechanical connection systems 15, a preferred embodiment is shown on the Figures 5, 5A and 6 .

Un tel système de liaison 15 s'inspire, par exemple, de celui décrit dans la demande de brevet FR 08 06011 au nom de la Demanderesse et comporte un mécanisme de liaison 20 à déformation élastique, entre la platine inférieure 8 liée au culot 1 et le support de flottement 9 lié au système d'accélération 5, et un dispositif de commande 21 du mécanisme de liaison 20 pour entraîner la séparation du culot 1 (platine inférieure) du système d'accélération et de basculement 5 (support de flottement), et des parties assemblées des connecteurs 11, 12, 13.Such a connection system is inspired, for example, by that described in the patent application. FR 08 06011 in the name of the Applicant and comprises a linkage mechanism 20 with elastic deformation, between the lower plate 8 connected to the base 1 and the floating support 9 connected to the acceleration system 5, and a control device 21 of the connecting mechanism 20 to cause separation of the base 1 (bottom plate) of the acceleration and tilting system 5 (floating support), and assembled parts of the connectors 11, 12, 13.

En particulier, le mécanisme de liaison 20 se compose, selon l'axe longitudinal XS de chaque système 15, parallèle à l'axe X du composite, d'une tige élastiquement déformable 22 liée à la platine 8, d'une aiguille coulissante 23 liée au dispositif de commande 21 et coopérant avec la tige, et d'un corps cylindrique annulaire 24 fixé au support de flottement 9 et portant un élément à butée axiale annulaire 25 pour la tige élastiquement déformable.In particular, the connecting mechanism 20 consists, along the longitudinal axis XS of each system 15, parallel to the axis X of the composite, of an elastically deformable rod 22 connected to the plate 8, of a sliding needle 23 linked to the control device 21 and cooperating with the rod, and an annular cylindrical body 24 fixed to the floating support 9 and carrying an annular axial abutment element 25 for the elastically deformable rod.

Pour rappel, la tige 22 présente une extrémité élargie élastiquement déformable qui est réalisée sous la forme d'une tête sphérique 27 d'un diamètre supérieur à celui de la tige et ayant deux fentes traversantes 28 ménagées dans deux plans longitudinaux perpendiculaires pour délimiter ainsi quatre quartiers ou pétales identiques comme le montre la figure 5A. Aussi, pour assurer une certaine élasticité de l'extrémité, les fentes 28 se prolongent dans la tige 22 au-delà de la tête sphérique 27 en formant ainsi des doigts allongés (quartiers) 29 à tête sphérique élastiquement déformables. Grâce aux fentes, les doigts 29 peuvent se rapprocher radialement les uns vers les autres en direction de l'axe XS et, donc, diminuer le diamètre initial de la tête sphérique 27, qui occupe une position ouverte sur les figures 5, 5A et 6, sous un moindre effort, comme on le verra plus tard. L'extrémité opposée de la tige présente une partie filetée 31 qui traverse un trou 32 ménagé dans la platine inférieure et qui reçoit un écrou de serrage 33 fixant la tige à la platine inférieure selon l'axe XS.As a reminder, the rod 22 has an elastically deformable widened end which is in the form of a spherical head 27 of a diameter greater than that of the rod and having two through slots 28 formed in two perpendicular longitudinal planes to thus delimit four identical quarters or petals as shown in Figure 5A . Also, to provide some elasticity of the end, the slots 28 extend in the rod 22 beyond the spherical head 27 thereby forming elongate fingers (quarters) 29 with an elastically deformable spherical head. Thanks to the slots, the fingers 29 can move radially towards each other in the direction of the axis XS and, therefore, reduce the initial diameter of the spherical head 27, which occupies an open position on the Figures 5, 5A and 6 under a lesser effort, as will be seen later. The opposite end of the rod has a threaded portion 31 which passes through a hole 32 formed in the lower plate and which receives a clamping nut 33 fixing the rod to the lower plate along the axis XS.

L'aiguille 23 présente une forme cylindrique allongée dont une extrémité 34 est lisse et s'introduit par ajustement dans le canal interne cylindrique 26 délimité par les doigts allongés déformables 29 à tête sphérique 27 de la tige. La distance d'introduction de l'extrémité lisse 34 dans la tête sphérique pour maintenir celle-ci en position initiale ouverte, est définie par un épaulement externe 35 de l'extrémité lisse 34, qui bute axialement contre l'extrémité élargie à tête sphérique 27 de la tige.The needle 23 has an elongated cylindrical shape, one end 34 is smooth and is introduced by adjustment in the cylindrical inner channel 26 defined by the elongated deformable fingers 29 with spherical head 27 of the rod. The insertion distance of the smooth end 34 into the spherical head to maintain it in the open initial position, is defined by an outer shoulder 35 of the smooth end 34, which abuts axially against the enlarged spherical end. 27 of the stem.

L'extrémité opposée 36 de l'aiguille est filetée pour s'engager par vissage dans un écrou de fixation 37 reliant le dispositif de commande 21 à l'aiguille par l'intermédiaire d'une vis 38 dont la tige filetée 39 coopère avec l'écrou pour venir buter contre l'extrémité filetée 36 de l'aiguille. Ainsi, l'aiguille 23 et la vis 38 forment un tout relié par l'écrou de liaison 37. Un jeu axial existe entre le dispositif de commande 21 et la tête 40 de la vis 38 de manière à absorber quelques mouvements longitudinaux dus à l'environnement extérieur au montage.The opposite end 36 of the needle is threaded to engage by screwing in a fixing nut 37 connecting the control device 21 to the needle by means of a screw 38 whose threaded rod 39 cooperates with the nut to abut against the threaded end 36 of the needle. Thus, the needle 23 and the screw 38 form a whole connected by the connecting nut 37. An axial clearance exists between the control device 21 and the head 40 of the screw 38 so as to absorb some longitudinal movements due to the environment outside the assembly.

Le corps cylindrique 24 et l'élément à butée 25 sont situés entre le support de flottement 9 et la platine 8. Plus particulièrement, le corps cylindrique 24 comporte un trou axial 41 qui est traversé coaxialement par l'aiguille 23 et qui entoure les extrémités coopérantes respectivement à tête sphérique 27 de la tige et lisse 34 de l'aiguille. Ce corps cylindrique 24 se termine, d'un côté, par un filetage 42 se vissant dans un trou taraudé 43 du support de flottement 9 et, de l'autre côté, par un taraudage 44 prévu en sortie du trou axial et se vissant dans un filetage 45 de l'élément à butée axiale annulaire 25. Celui-ci a son trou axial 46 en continuité de celui du corps, pour le passage de la tige, lequel trou 46 se termine, du côté de l'aiguille, par une portée ou cuvette sphérique 47 contre laquelle s'applique la tête sphérique 27 de la tige. Bien entendu, les dimensions de la portée 47 et de la tête 27 sont concordantes. Ainsi, le contact entre l'élément à butée 25 et la tige élastiquement déformable 22 s'effectue par une portion de surface sphérique annulaire autorisant un débattement angulaire relatif de la tige 22 liée à la platine 8 par rapport au corps 24 lié au support de flottement 9 dans toutes les directions à la manière d'une articulation à rotule. On comprend ainsi que le serrage de l'écrou 33 de la tige 22 sur la platine 8 tend à tirer la tige contre la platine et donc à presser les doigts élastiquement déformables 29 contre la portée sphérique 47 et, par suite, à pincer l'extrémité lisse 34 de l'aiguille.The cylindrical body 24 and the abutment element 25 are located between the floating support 9 and the plate 8. More particularly, the cylindrical body 24 has an axial hole 41 which is coaxially traversed by the needle 23 and which surrounds the ends. cooperating respectively spherical head 27 of the rod and smooth 34 of the needle. This cylindrical body 24 terminates, on one side, by a thread 42 screwing into a threaded hole 43 of the floating support 9 and, on the other side, by a tapping 44 provided at the outlet of the axial hole and screwing into a thread 45 of the annular axial abutment element 25. The latter has its axial hole 46 in continuity with that of the body, for the passage of the rod, which hole 46 ends, on the needle side, by a sphere or spherical bowl 47 against which the spherical head 27 of the stem is applied. Of course, the dimensions of the span 47 and the head 27 are concordant. Thus, the contact between the stop element 25 and the elastically deformable rod 22 is effected by an annular spherical surface portion allowing a relative angular displacement of the rod 22 connected to the plate 8 relative to the body 24 connected to the support of floating 9 in all directions in the manner of a ball joint. It is thus understood that the tightening of the nut 33 of the rod 22 on the plate 8 tends to pull the rod against the plate and thus to press the elastically deformable fingers 29 against the spherical bearing 47 and, consequently, to pinch the smooth end 34 of the needle.

L'ajustement du corps cylindrique 24 et de l'élément à butée 25 entre le support de flottement 9 et la platine inférieure 8 s'effectue, après les avoir montés autour de la tige 22, en amenant au contact l'élément à butée 25 contre la platine 8 et le corps 24 contre le support 9, et ce par l'intermédiaire des liaisons par vissage.The cylindrical body 24 and the stop element 25 are adjusted between the floating support 9 and the bottom plate 8 after being mounted around the rod 22, bringing the stop element 25 into contact with each other. against the plate 8 and the body 24 against the support 9, and this through the screw connections.

Par cet agencement, l'écrou de retenue initialement prévu dans la demande précitée est supprimé et évite, entre autres, des problèmes inhérents liés à la faible épaisseur de sa paroi latérale à taraudage via laquelle passe l'effort de traction important qui se produit lors de la séparation de chaque système de liaison.By this arrangement, the retaining nut initially provided in the aforementioned application is eliminated and avoids, inter alia, inherent problems related to the small thickness of its threaded side wall through which passes the significant tensile force that occurs during the separation of each link system.

Par ailleurs, chacun des systèmes 15 comprend de plus un ressort de compression 50 prévu autour de la vis 38, entre le dispositif de commande 21 et l'écrou de fixation 37. Ce ressort de compression 50 empêche le recul axial de l'aiguille évitant tout déverrouillage intempestif du système avant le lancement de la munition, du fait que ces systèmes de liaison 15 sont utilisés dans des environnements sévères, par exemple, à fortes vibrations. Ce ressort 50 remplace avantageusement l'anneau élastiquement déformable prévu dans la réalisation antérieure, qui, à cause de la suppression de l'écrou de retenue, aurait dû être déplacé dans le trou de passage du corps calibré, ce qui aurait présenté des risques de blocage de la sphère par le coincement des débris de l'anneau entre les doigts de celle-ci, lors de la séparation des systèmes.Furthermore, each of the systems 15 further comprises a compression spring 50 provided around the screw 38, between the control device 21 and the fixing nut 37. This compression spring 50 prevents the axial retraction of the needle avoiding any inadvertent unlocking of the system before the launch of the munition, because these linkage systems 15 are used in harsh environments, for example, high vibration. This spring 50 advantageously replaces the elastically deformable ring provided in the previous embodiment, which, because of the removal of the retaining nut, should have been moved in the passage hole of the calibrated body, which would have presented risks of blocking the sphere by jamming the debris of the ring between the fingers of the latter, during the separation of the systems.

La mise en place du montage 6, après fixation des platines de support 8 et 9 respectivement sur le culot 1 et le système d'accélération 5, et vissage des parties concernées 11A, 11 B, 12A, 12B, 13A, 13B des connecteurs électriques sur celles-ci, ne soulève pas de difficultés.The installation of the assembly 6, after fixing the support plates 8 and 9 respectively on the base 1 and the acceleration system 5, and screwing the relevant parts 11A, 11B, 12A, 12B, 13A, 13B electrical connectors on these, does not raise difficulties.

En effet, grâce à l'agencement des systèmes de liaison 15 en deçà de l'arc de cercle AC et de la butée axiale 16 à tige 17 entre les platines, en formant un plan P1 parallèle au plan P des connecteurs, les efforts axiaux parallèles des systèmes pour vaincre la raideur des éléments d'étanchéité 11C, 12C, 13C des connecteurs notamment d'extrémité et solidariser les mécanismes de liaison 20 passent ainsi perpendiculairement au plan des connecteurs. De la sorte, le support de flottement ou platine supérieure 9 ne bascule pas et reste parallèle à la platine inférieure 8. Concernant les mécanismes de liaison 20 des systèmes, les extrémités lisses 34 des aiguilles 23 sont alors insérées dans les canaux 26 des sphères élastiquement déformables 27 portées par les éléments de butée 25 à portée sphérique 47 des corps 24, empêchant leur sortie et verrouillant le montage 6.Indeed, thanks to the arrangement of the connection systems 15 below the arc of the circle AC and the axial abutment 16 to rod 17 between the plates, forming a plane P1 parallel to the plane P of the connectors, the axial forces Parallels of the systems to overcome the stiffness of the sealing elements 11C, 12C, 13C including end connectors and secure the connecting mechanisms 20 and pass perpendicularly to the plane of the connectors. In this way, the floating support or upper platen 9 does not tilt and remains parallel to the bottom plate 8. Regarding the linkage mechanisms 20 of the systems, the smooth ends 34 of the needles 23 are then inserted into the channels 26 of the spheres elastically deformable 27 carried by the abutment members 25 with spherical bearing 47 of the bodies 24, preventing their exit and locking the assembly 6.

Le passage de ce dernier de la position verrouillée (figures 5, 5A, 6) à la position déverrouillée (figure 7) se déroule de manière sensiblement analogue à la réalisation antérieure et ne sera que brièvement décrit.The passage of the latter from the locked position ( Figures 5, 5A , 6 ) to the unlocked position ( figure 7 ) proceeds in a substantially similar manner to the previous embodiment and will only be briefly described.

Lors de la mise à feu de la munition suite à un ordre de tir dont certaines informations passent par les connecteurs électriques, le dispositif de commande 21 de chaque système de liaison 15 (solidaire du système d'accélération 5, alors initié) commence son déplacement axial ou coulissement selon la flèche F (figure 7), neutralise le jeu entre la tête 40 de la vis 38 et celui-ci et tire sur l'aiguille 23. L'effort de traction engendré est tel qu'il permet la sortie de l'extrémité lisse 34 de la tête sphérique 27 et le déplacement se poursuit jusqu'au moment où l'épaulement 35 de l'aiguille 23 vient au contact du fond transversal 51 du corps 24. Les mécanismes de liaison 20 sont alors déverrouillés mais non séparés, les parties des connecteurs sont toujours raccordées, et le ressort de compression 50 s'allonge progressivement.When firing the ammunition following a firing order of which certain information passes through the electrical connectors, the control device 21 of each linkage system 15 (integral with the acceleration system 5, then initiated) begins its movement. axial or sliding according to the arrow F ( figure 7 ), neutralizes the clearance between the head 40 of the screw 38 and the latter and pulls on the needle 23. The traction force generated is such that it allows the output of the smooth end 34 of the spherical head 27 and the displacement continues until the shoulder 35 of the needle 23 comes into contact with the transverse bottom 51 of the body 24. The connecting mechanisms 20 are then unlocked but not separated, the parts of the connectors are always connected, and the compression spring 50 is progressively longer.

Le déplacement continue et l'aiguille 23 de chaque système 15 entraîne avec elle, par le contact de l'épaulement 35, le corps cylindrique 24 et l'élément de butée associé 25. Contrairement à la réalisation précédente pour laquelle l'aiguille tire sur l'écrou de retenue (supprimé ici), lequel tire par son filetage limité tout l'ensemble, chaque aiguille pousse le corps contre le support de flottement 9 et le tout est alors tiré sans difficulté. Sous l'action de la portée sphérique 47 de l'élément 25 qui s'éloigne de la tige 23, les doigts élastiquement déformables 29 convergent progressivement radialement les uns vers les autres en direction de l'axe XC jusqu'à venir se toucher lorsque le trou axial 46 de l'élément à butée annulaire 25 arrive et passe sur la tête sphérique 27 de ladite tige. La tête sphérique occupe alors la position fermée et les mécanismes de liaison 20 des systèmes de liaison 15 sont déverrouillés.The continuous displacement and the needle 23 of each system 15 carries with it, by the contact of the shoulder 35, the cylindrical body 24 and the associated stop member 25. Unlike the previous embodiment for which the needle pulls on the retaining nut (removed here), which pulls through its threading limited all together, each needle pushes the body against the floating support 9 and all is then shot without difficulty. Under the action of the spherical bearing 47 of the element 25 which moves away from the rod 23, the elastically deformable fingers 29 converge progressively radially towards each other in the direction of the axis XC until they touch each other when the axial hole 46 of the annular abutment element 25 arrives and passes on the spherical head 27 of said rod. The spherical head then occupies the closed position and the connecting mechanisms 20 of the linking systems 15 are unlocked.

La séparation du montage 6 est alors acquise et se poursuit, c'est-à-dire que, comme le montre la figure 7, le support de flottement 9 fixé au système d'accélération 5 et la platine de support 8 fixée au culot 1 sont libérés l'un de l'autre, de même que le sont les parties 11A, 12A, 13A des parties 11 B, 12B, 13B des connecteurs vissés respectivement sur la platine 8 et le support de flottement 9. Le culot est définitivement séparé du reste de la munition.The separation of the assembly 6 is then acquired and continues, that is to say that, as shown in FIG. figure 7 , the floating support 9 fixed to the acceleration system 5 and the support plate 8 fixed to the base 1 are released from each other, as are the parts 11A, 12A, 13A of the parts 11B, 12B, 13B connectors screwed respectively on the plate 8 and the floating support 9. The base is permanently separated from the rest of the ammunition.

Bien évidemment, tant qu'une mise à feu de celle-ci n'est pas ordonnée, il est possible de démonter puis de remonter le montage après sa mise en place, à des fins de maintenance notamment.Of course, as a firing thereof is not ordered, it is possible to dismantle and reassemble the assembly after its implementation, for maintenance in particular.
