Description

Le domaine technique de l'invention est celui des dispositifs permettant d'assurer une liaison électrique entre une masse reculante d'une arme et un bâti fixe.The technical field of the invention is that of devices for ensuring an electrical connection between a receding mass of a weapon and a fixed frame.

Dans les armes connues la liaison électrique entre la masse reculante de l'arme et le berceau fixe est assurée par un toucheau de contact fixe qui vient en appui avec un contact solidaire de la masse reculante.In known weapons the electrical connection between the receding mass of the weapon and the fixed cradle is provided by a fixed contact touch which comes into contact with a contact integral with the receding mass.

L'énergie électrique véhiculée avec une telle solution est réduite (de l'ordre de quelques centaines de milli joules) et suffit à l'initiation d'un inflammateur électrique de la munition.The electrical energy conveyed with such a solution is reduced (on the order of a few hundred milli joules) and is sufficient for the initiation of an electric igniter ammunition.

Cette solution est mal adaptée aux armes mettant en oeuvre des allumeurs à plasma. En effet ces derniers sont alimentés par des impulsions de haute tension (de l'ordre de 5 à 20 kilo volts) et de haute énergie (de l'ordre de quelques centaines de kilo Joules).This solution is ill-suited to weapons using plasma igniters. Indeed these are fed by high voltage pulses (of the order of 5 to 20 kilo volts) and high energy (around a few hundreds of kilograms Joules).

Les caractéristiques de contact des toucheaux sont telles que l'énergie véhiculée provoquerait une fusion des contacts et la destruction de l'alimentation électrique.The touch contact characteristics are such that the energy carried would cause a fusion of contacts and destruction of the power supply.

Il n'est pas souhaitable par ailleurs, compte tenu des contraintes d'intégration, d'utiliser des câbles de grande longueur fixés, d'un côté au berceau et de l'autre à la masse reculante, et accompagnant le mouvement de recul de l'arme.It is also undesirable, given the integration constraints, using large cables length fixed, on one side to the cradle and on the other to earth recoiling, and accompanying the recoil movement of the weapon.

C'est le but de l'invention que de proposer un dispositif de liaison électrique permettant de pallier de tels inconvénients.It is the object of the invention to propose a device electrical connection to overcome such disadvantages.

Ainsi le dispositif selon l'invention permet d'assurer de façon fiable la connexion entre une masse reculante et un berceau d'une arme tout en autorisant le passage d'énergie importantes (de l'ordre de plusieurs centaines de kilo Joules).Thus the device according to the invention makes it possible to ensure reliably the connection between a receding mass and a cradle of a weapon while allowing the passage of energy significant (of the order of several hundred kilograms Joules).

Ainsi l'invention a pour objet un dispositif assurant la liaison électrique entre une masse reculante d'une arme et un berceau fixe, dispositif caractérisé en ce qu'il comporte au moins un connecteur formé d'une prise mâle et d'une prise femelle, une des prises du connecteur étant solidaire du berceau et l'autre prise étant solidaire de la masse reculante, le recul de cette dernière entraínant la déconnexion.Thus, the subject of the invention is a device ensuring the electrical connection between a receding mass of a weapon and a fixed cradle, device characterized in that it comprises at minus a connector formed by a male plug and a plug female, one of the connector sockets being secured to the cradle and the other socket being secured to the mass receding, the receding of the latter causing the disconnection.

Avantageusement la prise solidaire du berceau pourra être solidaire d'un moyen moteur permettant le déplacement de la prise solidaire du berceau de façon à assurer la déconnexion des prises lorsque la masse reculante est dans une position de repos avant tir.Advantageously, the solid socket of the cradle can be secured to a motor means allowing the displacement of the socket secured to the cradle so as to ensure disconnection holds when the receding mass is in a position rest before shooting.

Les fiches de la prise mâle pourront être solidaires d'un support réalisé en un matériau isolant souple.The plugs of the male plug may be integral with a support made of a flexible insulating material.

La prise femelle pourra comporter au moins deux douilles de contact cylindriques dont le diamètre interne sera légèrement inférieur à celui des fiches de contact de la prise mâle, chaque douille comportant une fente longitudinale lui donnant une possibilité de déformation radiale lors de l'introduction de la fiche.The female socket may include at least two sockets contact cylinders with an internal diameter slightly lower than that of the contact cards of the male plug, each socket having a longitudinal slot giving it a possibility of radial deformation during the introduction of the sheet.

La prise mâle pourra comporter au moins deux fiches de contact dont la longueur libre hors de la prise sera supérieure ou égale à la longueur des douilles.The male plug may include at least two plugs contact whose free length outside the socket will be greater than or equal to the length of the sockets.

La prise mâle pourra être solidaire du berceau et la prise femelle solidaire de la masse reculante.The male plug may be secured to the cradle and the female socket secured to the receding mass.

L'invention sera mieux comprise à la lecture de la description qui va suivre d'un mode particulier de réalisation, description faite en référence aux dessins annexés et dans lesquels :

  • la figure 1 est une vue d'ensemble schématique montrant une arme équipée d'un connecteur selon l'invention,
  • la figure 2 montre le connecteur seul à l'état connecté,
  • la figure 3 représente en perspective un mode de réalisation d'un connecteur femelle démonté,
  • la figure 4 représente en perspective une douille de contact du connecteur femelle,
  • les figures 5a et 5b sont deux vues en perspective du connecteur femelle assemblé.
The invention will be better understood on reading the description which follows of a particular embodiment, description made with reference to the appended drawings and in which:
  • FIG. 1 is a schematic overview showing a weapon equipped with a connector according to the invention,
  • FIG. 2 shows the connector alone in the connected state,
  • FIG. 3 shows in perspective an embodiment of a disassembled female connector,
  • FIG. 4 is a perspective view of a contact socket of the female connector,
  • Figures 5a and 5b are two perspective views of the assembled female connector.

En se reportant à la figure 1, une arme 1 comporte une masse reculante 2 montée coulissante par rapport à un berceau 3. La masse reculante 2 comprend un tube qui est équipé à sa partie arrière d'un manchon de culasse 5, à l'intérieur duquel se déplace un coin de fermeture 4. Une telle structure d'arme est bien connue de l'Homme du Métier et il n'est pas nécessaire de la décrire plus en détails.Referring to Figure 1, a weapon 1 has a recoiling mass 2 sliding mounted relative to a cradle 3. The receding mass 2 comprises a tube which is equipped at its rear part of a cylinder head sleeve 5, inside which moves a closing corner 4. Such a structure weapon is well known to the skilled person and it is not necessary to describe it in more detail.

Le tube 2 reçoit ici une munition dont seul le culot obturateur 6 est représenté. Ce culot porte un tube allumeur (non représenté) qui sera par exemple un allumeur à plasma tel que décrit par les brevets FR2807610 et FR2807611. L'allumeur est initié par un courant électrique qui lui parvient par l'intermédiaire de deux plots de contacts 7a et 7b solidaires du culot 4 et isolés électriquement l'un de l'autre.The tube 2 here receives an ammunition of which only the base shutter 6 is shown. This base carries an igniter tube (not shown) which will be for example a plasma igniter as described by patents FR2807610 and FR2807611. The igniter is initiated by an electric current which arrives via two contact pads 7a and 7b integral with the base 4 and electrically insulated one of the other.

Lorsque le coin 4 est fermé, ces plots sont en contact électrique avec deux touchaux 8a et 8b solidaires du coin 4 et qui sont reliés à un générateur électrique 9.When corner 4 is closed, these studs are in contact electric with two touchaux 8a and 8b integral with the corner 4 and which are connected to an electric generator 9.

Conformément à l'invention la liaison électrique entre les toucheaux 8a, 8b et le générateur 9 se fait par l'intermédiaire d'un connecteur 10 qui comprend une prise mâle 11 et une prise femelle 12.According to the invention the electrical connection between the touches 8a, 8b and the generator 9 is done by via a connector 10 which includes a socket male 11 and female socket 12.

Ici la prise mâle 11 est solidaire du berceau 3 de l'arme et la prise femelle 12 est solidaire de la masse reculante 2 et plus particulièrement du coin 4.Here the male socket 11 is integral with the cradle 3 of the weapon and the socket 12 is integral with the receding mass 2 and more particularly from corner 4.

Une disposition inverse serait bien entendu possible.A reverse arrangement would of course be possible.

Les proportions relatives du connecteur 10 et de l'arme 1 sont bien entendu très exagérées sur la figure 1, cela afin de faciliter la description du connecteur tout en situant celui ci par rapport à l'arme. Le connecteur selon l'invention est une pièce de dimensions bien inférieures à celle du coin de culasse. Un connecteur selon l'invention forme ainsi, une fois assemblé, un parallélépipède d'environ 200 mm x 200 mm x 100 mm.The relative proportions of connector 10 and weapon 1 are of course very exaggerated in Figure 1, so to facilitate the description of the connector while locating this one in relation to the weapon. The connector according to the invention is a part of dimensions much smaller than that of the breech wedge. A connector according to the invention thus forms, when assembled, a parallelepiped of about 200 mm x 200 mm x 100 mm.

La prise femelle 12 est formée d'un corps 13 en matériau isolant électrique, par exemple en matière plastique, qui présente deux trous 14a, 14b à l'intérieur desquels sont disposées des douilles de contact cylindriques 15a, 15b en métal (par exemple en laiton). Le diamètre des trous 14a, 14b est plus faible de part et d'autre des douilles 15a,15b ainsi les douilles se trouvent immobilisées axialement par rapport au corps 13 par des épaulements 16. Les douilles 15a, 15b pourront être noyées dans le matériau du corps 13 qui pourra ainsi être surmoulé sur les douilles. Alternativement on pourra réaliser le corps 13 en deux parties qui seront rendues solidaires l'une de l'autre par exemple par vis. Cette solution permettra le démontage des douilles.The socket 12 is formed by a body 13 made of material electrical insulation, for example plastic, which has two holes 14a, 14b inside which are arranged in cylindrical contact sockets 15a, 15b in metal (for example brass). The diameter of the holes 14a, 14b is weaker on both sides of the sockets 15a, 15b as well the sockets are immobilized axially with respect to to the body 13 by shoulders 16. The sockets 15a, 15b may be embedded in the material of the body 13 which may thus being overmolded on the sockets. Alternatively we can realize the body 13 in two parts which will made integral with each other for example by screws. This solution will allow disassembly of the sockets.

Chaque douille 15a, 15b est reliée à un des touchaux 8a, 8b par un conducteur 17a, 17b qui traverse le coin de culasse 4.Each socket 15a, 15b is connected to one of the touchaux 8a, 8b by a conductor 17a, 17b which crosses the cylinder head corner 4.

La prise mâle 11 comporte un boítier 18 isolant fermé par un couvercle 19, également isolant, et fixé au boítier par exemple par vis. Le boítier 18 renferme deux fiches de contact 20a, 20b cylindriques qui traversent le couvercle par des orifices.The male plug 11 comprises an insulating housing 18 closed by a cover 19, also insulating, and fixed to the housing by example by screw. The case 18 contains two sheets of contact 20a, 20b cylindrical which pass through the cover by orifices.

Chaque fiche 20a, 20b présente une tête élargie 21a, 21b qui est reliée électriquement par soudure à un conducteur électrique 22a, 22b lui-même raccordé au générateur électrique 9.Each plug 20a, 20b has an enlarged head 21a, 21b which is electrically connected by solder to a conductor electric 22a, 22b itself connected to the generator electric 9.

Le boítier isolant 18 comporte une cavité interne à l'intérieur de laquelle se logent les têtes 21 des fiches 20. Cette cavité est remplie d'un matériau support isolant souple 23 (par exemple du silicone) qui entoure les têtes 21 des fiches. Par ailleurs les orifices du couvercle 19 ont un diamètre supérieur à celui des fiches (de quelques dixièmes de mm). De telles caractéristiques permettent de conférer aux fiches 20 une certaine liberté de mouvement qui autorise un pivotement limité de l'axe de chaque fiche par rapport au boítier 18.The insulating housing 18 has an internal cavity inside which the heads 21 of the plugs 20 are housed. This cavity is filled with a flexible insulating support material 23 (for example silicone) which surrounds the heads 21 of the sheets. Furthermore, the openings of the cover 19 have a diameter greater than that of the plugs (by a few tenths mm). Such characteristics make it possible to confer on sheets 20 a certain freedom of movement which authorizes a limited pivoting of the axis of each plug relative to the housing 18.

Une telle disposition facilite un bon positionnement des fiches 20a, 20b par rapport aux douilles 15a, 15b lors de l'établissement de la connexion. Such an arrangement facilitates good positioning of the plugs 20a, 20b with respect to sockets 15a, 15b when establishing the connection.

Les fiches 20a et 20b sont destinées à s'introduire dans les douilles 15a,15b de façon à assurer un contact électrique entre les conducteurs 22a, 22b et les conducteurs 17a,17b. La figure 2 montre ainsi les prises en position connectée.Sheets 20a and 20b are intended to be used in the sockets 15a, 15b so as to ensure electrical contact between the conductors 22a, 22b and the conductors 17a, 17b. The Figure 2 thus shows the sockets in the connected position.

La longueur des fiches 20a,20b qui s'étend au dehors du boítier 18 est choisie supérieure ou égale à celle des douilles 15a, 15b. Cela de façon à assurer une surface de contact maximale.The length of the plugs 20a, 20b which extends outside the box 18 is chosen to be greater than or equal to that of sockets 15a, 15b. This in order to ensure a surface of maximum contact.

Le diamètre interne des douilles 15a,15b est légèrement inférieur à celui des fiches de contact 20a,20b de la prise mâle 11. Par ailleurs chaque douille 15 comporte une fente longitudinale 24 qui lui confère une possibilité de déformation radiale lors de l'introduction de la fiche mâle 20. Une telle disposition augmente la qualité de la connexion électrique en diminuant les résistances électriques de contact.The internal diameter of the sockets 15a, 15b is slightly lower than that of the contact plugs 20a, 20b of the socket male 11. Furthermore, each socket 15 has a slot longitudinal 24 which gives it a possibility of radial deformation when inserting the male plug 20. Such an arrangement increases the quality of the connection electrical by decreasing the electrical resistances by contact.

Selon une autre caractéristique de l'invention la prise mâle 11 (donc celle solidaire du berceau) est fixée à un moyen moteur 25 qui est ici constitué par un vérin hydraulique dont le corps est solidaire du berceau 3 de l'arme et dont la tige 26 porte la prise mâle 11.According to another characteristic of the invention, taking male 11 (therefore the one secured to the cradle) is fixed to a motor means 25 which is here constituted by a jack hydraulic whose body is integral with the cradle 3 of the weapon and whose rod 26 carries the male plug 11.

Il est alors possible en commandant le vérin 25 de déplacer la prise mâle 11 par rapport à la prise femelle 12 de façon à assurer la connexion ou la déconnexion des prises (déplacements suivant la flèche d).It is then possible by ordering the cylinder 25 of move the male connector 11 relative to the female connector 12 so as to ensure the connection or disconnection of sockets (displacements according to arrow d).

Par ailleurs la prise femelle étant solidaire de la masse reculante, le recul de cette dernière lors du tir entraíne un déplacement relatif de la prise femelle par rapport à la prise mâle, donc la déconnexion.Furthermore, the female socket being integral with the mass receding, the recoil of the latter when fired results in a relative displacement of the socket relative to the male plug, therefore disconnection.

Le fonctionnement du dispositif est le suivant.The operation of the device is as follows.

Avant tir il est nécessaire de déplacer transversalement le coin de culasse 4 par rapport au tube 2 de l'arme, cela pour permettre le chargement de l'arme avec une munition. Pour permettre un tel déplacement du coin la prise mâle 11 doit être déconnectée de la prise femelle 12. On utilisera pour cela le vérin 25 qui permettra de commander la déconnexion (figure 1). Cette déconnexion assure également la sécurité de la mise à poste de la munition puisque aucune tension électrique ne peut alors être appliquée au coin de culasse 4.Before shooting it is necessary to move transversely the breech wedge 4 relative to the barrel 2 of the weapon, this to allow the loading of the weapon with ammunition. To allow such displacement of the corner the male plug 11 must be disconnected from socket 12. We will use for this the jack 25 which will control the disconnection (figure 1). This disconnection also ensures the ammunition safety since none electrical voltage cannot then be applied to the corner of cylinder head 4.

Après chargement et avant le tir on commande en sens inverse le vérin pour établir la connexion entre les prises 11 et 12 (figure 2). La souplesse des fiches 20 et les fentes 24 des douilles 15 assurent une connexion fiable et une bonne qualité du contact électrique. Le générateur 9 est alors actionné pour fournir l'énergie électrique à la munition au travers des conducteurs 22, 17 et du connecteur 10. Les caractéristiques électriques des contacts établis par le connecteur permettent de véhiculer une énergie électrique de l'ordre de plusieurs centaines de kilo Joules permettant l'initiation d'un allumeur à plasma.After loading and before firing we order in the direction reverses the cylinder to establish the connection between the sockets 11 and 12 (Figure 2). The flexibility of the 20 plugs and the slots 24 of the sockets 15 ensure a reliable and good connection quality of the electrical contact. The generator 9 is then actuated to supply electrical energy to the ammunition at through conductors 22, 17 and connector 10. The electrical characteristics of the contacts established by the connector allow to convey an electrical energy of the order of several hundred kilograms of Joules allowing initiation of a plasma igniter.

Le tir du projectile entraíne le recul de la masse reculante 2 (déplacement suivant la flèche D). Le recul entraíne automatiquement l'ouverture du connecteur électrique 10 sans contraintes mécaniques particulière. On commande le vérin 25, simultanément ou après le début du recul, de façon à éloigner la prise mâle 11 de la prise femelle. Une telle disposition assure que, lorsque la masse reculante reviendra en batterie à l'issue du recul, la connexion électrique ne se trouvera pas automatiquement rétablie ce qui autorisera l'ouverture du coin 4 pour permettre un rechargement.The shooting of the projectile causes the recoil of the mass backward 2 (displacement along arrow D). Hindsight automatically opens the electrical connector 10 without any particular mechanical constraints. We order the cylinder 25, simultaneously or after the start of recoil, so to move the male plug 11 away from the female plug. Such a provision ensures that when the receding mass returns in battery after recoil, the electrical connection is not will not automatically be restored which will allow opening the corner 4 to allow reloading.

Les figures 3 à 5b montrent un exemple d'un mode particulier de réalisation d'une prise femelle 12. Celle ci est ici formée de deux parties : un support 12a et une bride 12b, liée au support 12a par des vis. Support 12a et bride 12b sont réalisés en matériau isolant (plastique ou composite). Le support et la bride portent chacun deux demi-cylindres 27, 28 qui constituent les logements pour les douilles 15 (non représentées à la figure 3). Ces demi-cylindres sont délimités par des épaulements 16 assurant l'immobilisation axiale des douilles. Figures 3 to 5b show an example of a mode particular realization of a socket 12. This one is here formed of two parts: a support 12a and a flange 12b, linked to the support 12a by screws. Support 12a and flange 12b are made of insulating material (plastic or composite). The support and the flange each carry two half-cylinders 27, 28 which constitute the accommodation for sockets 15 (not shown in Figure 3). These half cylinders are delimited by shoulders 16 ensuring the axial immobilization of the sockets.

La figure 4 montre en perspective une douille 15 avant sa mise en place dans les logements 27, 28. La douille est réalisée en laiton et la fente 24 assure sa souplesse. Une tige conductrice 29 est solidaire de la douille à laquelle elle est fixée par soudure. Cette tige assure la conduite du courant au travers du support 12a qu'elle traverse par un trou (non représenté à la figure 3).Figure 4 shows in perspective a socket 15 before its placed in the housings 27, 28. The socket is made of brass and the slot 24 ensures its flexibility. A conductive rod 29 is integral with the socket to which it is fixed by welding. This rod ensures the conduct of the current through the support 12a which it crosses by a hole (not shown in Figure 3).

Les figures 5a et 5b montrent cette prise femelle 12 assemblée. La figure 5b montre également les deux tiges 29a et 29b qui sont chacune solidaire d'une douille 15. Les conducteurs 17a et 17b seront fixés à ces tiges par soudure lors du montage de la prise sur le coin de culasse.Figures 5a and 5b show this socket 12 Assembly. Figure 5b also shows the two rods 29a and 29b which are each secured to a socket 15. The conductors 17a and 17b will be fixed to these rods by welding when mounting the socket on the cylinder head corner.

A titre de variante il est possible de lier la prise femelle au berceau et la prise mâle à la masse reculante.Alternatively it is possible to link the socket female to the cradle and the male plug to the receding mass.

Il est également possible de définir un connecteur selon l'invention comportant plus de deux fiches. D'autres fiches pourront ainsi être prévues pour conduire un signal de programmation destiné à la munition ou bien pour conduire au berceau un signal de mesure de la température de la chambre de l'arme.It is also possible to define a connector according to the invention comprising more than two sheets. Other files may therefore be provided to conduct a signal programming intended for ammunition or to lead to cradle a room temperature measurement signal of the weapon.

Le connecteur selon l'invention est particulièrement bien adapté à la conduite d'un courant de forte tension tel qu'il est nécessaire pour l'initiation d'un allumeur à plasma. Il est cependant également possible d'utiliser le connecteur selon l'invention pour conduire un courant d'allumage d'intensité modérée (de l'ordre de l'ampère) par exemple pour l'allumage d'un allumeur classique. Dans ce cas le connecteur selon l'invention assure une excellente qualité de contact électrique entre masse reculante et berceau tout en étant de structure simple.The connector according to the invention is particularly well suitable for conducting a high voltage current such that is necessary for the initiation of a plasma igniter. he however, it is also possible to use the connector according to the invention for conducting an ignition current of moderate intensity (of the order of an ampere) for example for the ignition of a conventional igniter. In this case the connector according to the invention provides excellent contact quality electric between recoiling mass and cradle while being simple structure.
