Un tel dispositif est deja connu du document EP-A-0 060 187.Such a device is already known from document EP-A-0 060 187.

L'invention se rapporte, plus particulièrement, à des boîtiers, par exemple de calculateurs, présentant un élément femelle dans le fond duquel s'érigent des languettes mâles et un élément mâle comportant des organes femelles destinés à recevoir les languettes. Généralement, dans ces calculateurs, il est prévu un grand nombre de connexions et les languettes présentent toujours une certaine fragilité. Il est donc nécessaire que l'insertion des éléments s'effectue dans une direction constante et sans efforts importants.The invention relates, more particularly, to housings, for example of computers, having a female element in the bottom of which are erected male tongues and a male element comprising female members intended to receive the tongues. Generally, in these computers, there is a large number of connections and the tongues always have a certain brittleness. It is therefore necessary that the insertion of the elements is carried out in a constant direction and without significant efforts.

L'un des buts de la présente invention est de réaliser un dispositif qui répond à ces impératifs.One of the aims of the present invention is to provide a device which meets these requirements.

Le dispositif, selon l'invention, est destiné à l'accouplement de deux éléments de boîtiers d'un connecteur électrique de forme générale parallélépipédique comprenant un élément femelle destiné à recevoir un élément mâle, ledit dispositif étant caractérisé en ce que l'un des éléments comporte deux tétons, sur chacune de ses faces opposées, tandis que l'autre élément comporte, montés pivotants sur chacune de ses deux faces opposées correspondantes, deux secteurs dentés, chaque secteur présentant une fente débouchant dans une came, chaque came étant destinée à coopérer avec un téton correspondant et des moyens étant montés sur l'élément comportant les secteurs dentés pour commander la rotation de ces derniers dans un sens, vers une première position d'ouverture et la rotation dans le sens opposé vers une seconde position de verrouillage.The device according to the invention is intended for coupling two elements of housings of an electrical connector of generally parallelepiped shape comprising a female element intended to receive a male element, said device being characterized in that one of the elements comprises two studs, on each of its opposite faces, while the other element comprises, pivotally mounted on each of its two opposite opposite faces, two toothed sectors, each sector having a slot opening into a cam, each cam being intended to cooperate with a corresponding stud and means being mounted on the element comprising the toothed sectors to control the rotation of the latter in one direction, towards a first open position and the rotation in the opposite direction towards a second locking position.

Suivant une caractéristique de détail de l'invention, les moyens de commande des secteurs dentés sont constitués par un levier solidaire de l'un des secteurs, ceux-ci engrenant l'un avec l'autre, les cames des secteurs étant symétriques par rapport à un plan perpendiculaire médian à un plan passant par des axes autour desquels pivotent les secteurs.According to a detail characteristic of the invention, the control means of the toothed sectors are constituted by a lever secured to one of the sectors, these meshing with one another, the cams of the sectors being symmetrical with respect to to a perpendicular median plane to a plane passing through axes around which the sectors pivot.

Selon une variante de réalisation de l'invention, le dispositif comporte, sur chacune des deux faces opposées, un pignon de renvoi inséré entre les secteurs et des moyens pour entraîner sélectivement les pignons de renvoi dans un sens correspondant à la première position d'ouverture et, dans le sens opposé, correspondant à la seconde position de verrouillage.According to an alternative embodiment of the invention, the device comprises, on each of the two opposite faces, a return pinion inserted between the sectors and means for selectively driving the return pinions in a direction corresponding to the first open position. and, in the opposite direction, corresponding to the second locking position.

Suivant une caractéristique constructive de l'invention, les moyens pour entraîner le pignon de renvoi sont constitués par un levier présentant deux branches solidaires chacune du pignon de renvoi correspondant.According to a constructive characteristic of the invention, the means for driving the return pinion consist of a lever having two branches each secured to the corresponding return pinion.

Suivant encore une autre variante de réalisation de l'invention, les moyens pour entraîner le pignon de renvoi sont constitués par un étrier monté coulissant sur l'élément de boîtier comportant les secteurs et comportant des crémaillères coopérant avec les pignons de renvoi.According to yet another alternative embodiment of the invention, the means for driving the return pinion consist of a bracket mounted to slide on the housing element comprising the sectors and comprising racks cooperating with the return pinions.

Suivant une autre caractéristique, le dispositif comporte des moyens pour caler l'étrier sur l'élément de boîtier correspondant, dans deux positions extrèmes opposées, dont l'une correspond à la première position d'ouverture et l'autre à la seconde position de verrouillage.According to another characteristic, the device comprises means for wedging the stirrup on the corresponding housing element, in two opposite extreme positions, one of which corresponds to the first open position and the other to the second position of locking.

Enfin, suivant une caractéristique constructive de l'invention, l'élément pourvu du levier comporte un crochet élastique destiné à coopérer avec ledit levier pour bloquer celui-ci dans la position de verrouillage.Finally, according to a constructive characteristic of the invention, the element provided with the lever comprises an elastic hook intended to cooperate with said lever to lock the latter in the locking position.

L'élément pourvu du levier comporte des butées limitant le basculement dudit levier vers la position d'ouverture et des moyens pour maintenir ledit levier dans cette position.The element provided with the lever comprises stops limiting the tilting of said lever towards the open position and means for maintaining said lever in this position.

L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés à titre d'exemple seulement et représentés aux dessins annexés, dans lesquels :The invention will now be described in more detail with reference to particular embodiments given by way of example only and shown in the accompanying drawings, in which:

Figure 1 est une vue en perspective éclatée d'un connecteur comportant un dispositif d'accouplement, selon l'invention.Figure 1 is an exploded perspective view of a connector comprising a coupling device according to the invention.

Figure 5 montre en perspective éclatée une troisième forme d'exécution de l'invention.Figure 5 shows in exploded perspective a third embodiment of the invention.

Aux figures 1 et 2, on a représenté un élément de boîtier femelle 1 de forme générale parallélépipédique avec deux parois longitudinales 3 et deux parois d'extrémités 4.FIGS. 1 and 2 show a female housing element 1 of generally parallelepiped shape with two longitudinal walls 3 and two end walls 4.

L'élément 1 comporte trois compartiments 2 et sur ses parois latérales 3, au voisinage d'une extrémité 1a, font saillie deux tétons 6 et 6a.The element 1 has three compartments 2 and on its side walls 3, in the vicinity of an end 1 a , project two studs 6 and 6 a .

L'élément de boîtier 1 est destiné à recevoir un élément de boîtier complémentaire 10 qui présente des parties 11 destinées à s'engager dans les compartiments 2 et qui sont raccordées audit élément 10 par un épaulement 12 destiné à porter contre l'extrémité 1a.The housing element 1 is intended to receive a complementary housing element 10 which has parts 11 intended to engage in the compartments 2 and which are connected to said element 10 by a shoulder 12 intended to bear against the end 1 a .

Les parties 11 peuvent faire partie intégrante de l'élément 10 ou être formées par des étuis insérés dans les logements dudit élément.The parts 11 may be an integral part of the element 10 or be formed by cases inserted in the housings of said element.

Dans le fond de chaque compartiment 2 peut s'ériger une série de languettes reliées à des circuits électriques, tandis que dans les parties 11 s'étendent des séries d'organes femelles reliés à des circuits électriques et destinés à coopérer avec les languettes. Ces organes bien connus ne sont pas représentés ici.In the bottom of each compartment 2 can be erected a series of tongues connected to electrical circuits, while in parts 11 extend series of female members connected to electrical circuits and intended to cooperate with the tongues. These well known bodies are not shown here.

Sur un axe 15 de l'élément 10 s'articule un levier 16 affectant une forme en U avec deux branches 17 et une âme 18 qui constitue la poignée de manoeuvre.On an axis 15 of the element 10 is articulated a lever 16 affecting a U-shape with two branches 17 and a core 18 which constitutes the operating handle.

Chaque branche 17, le long d'un bord 17a, forme un coude 17b raccordé à une partie 17c, tandis que le long du bord opposé au bord 17a et à son extrémité libre chaque branche 17 forme un secteur 24 présentant deux dents 20.Each branch 17, along an edge 17a, forms an elbow 17b connected to a part 17c, while along the edge opposite the edge 17a and at its free end each branch 17 forms a sector 24 having two teeth 20.

Les dents 20 sont situées sur un arc de cercle ayant pour centre l'axe 15.The teeth 20 are located on an arc having the axis 15 at the center.

L'extrémité du secteur 24 adjacente à la partie 17c comporte une fente 21 s'ouvrant sur une came 22 constituée par une rainure arquée qui va en se rapprochant de l'axe 15 depuis la fente 21 jusqu'à son fond.The end of the sector 24 adjacent to the part 17c comprises a slot 21 opening onto a cam 22 constituted by an arcuate groove which moves towards the axis 15 from the slot 21 to its bottom.

Sur des axes 25 parallèles à l'axe 15 sont montés pivotants de chaque côté de l'élément 10, des secteurs 26 présentant, sur un arc ayant pour centre l'axe 25, des dents 27 qui engrènent avec les dents 20.On axes 25 parallel to axis 15 are pivotally mounted on each side of the element 10, sectors 26 having, on an arc having the axis 25 as their center, teeth 27 which mesh with the teeth 20.

Le secteur comporte une fente 28 qui s'ouvre sur son bord latéral et qui débouche sur une came 29 constituée par une rainure arquée qui va en se rapprochant de l'axe 25 depuis son extrémité adjacente à la fente 28 vers son fond.The sector has a slot 28 which opens on its lateral edge and which opens onto a cam 29 formed by an arcuate groove which moves towards the axis 25 from its end adjacent to the slot 28 towards its bottom.

Les cames 22 et 29 sont symétriques par rapport à un plan, coupant en un point intermédiaire médian, le plan passant par les axes 15 et 25.Cams 22 and 29 are symmetrical with respect to a plane, intersecting at a median intermediate point, the plane passing through axes 15 and 25.

L'élément 10 présente des butées 30 qui limitent le basculement du levier 16 dans un sens correspondant à l'ouverture, les faces internes des branches 17 étant pourvues d'un bossage 31 pour maintenir le levier 16 dans la position ouverte.The element 10 has stops 30 which limit the tilting of the lever 16 in a direction corresponding to the opening, the internal faces of the branches 17 being provided with a boss 31 to hold the lever 16 in the open position.

L'élément 10 est pourvu d'un crochet destiné à coopérer avec la surface latérale de l'âme 18 pour bloquer ledit levier 16 dans la position de fermeture moyennant une légère déformation élastique dudit crochet 32.The element 10 is provided with a hook intended to cooperate with the lateral surface of the core 18 to block said lever 16 in the closed position by means of a slight elastic deformation of said hook 32.

Le dispositif, selon l'invention, trouve une application particulièrement intéressante dans des boîtiers de calculateurs qui comportent un grand nombre de languettes mâles devant coopérer avec un grand nombre d'organes de contacts femelles et dans lesquels il est nécessaire que l'insertion de l'élément mâle dans l'élément femelle s'effectue rigoureusement parallèlement aux axes des languettes afin d'éviter toute déformation de celles-ci.The device according to the invention finds a particularly interesting application in computer housings which include a large number of male tabs which have to cooperate with a large number of female contact members and in which it is necessary for the insertion of the 'male element in the female element is carried out strictly parallel to the axes of the tongues to avoid any deformation thereof.

Comme on le voit à la figure 1, l'élément 10 est présenté le levier 16 en position d'ouverture, afin que les tétons 6 et 6a s'insèrent respectivement dans les fentes 21 et 28, puis le levier 16 est pivoté autour de l'axe 15 vers la position de fermeture et de verrouillage en coopérant avec le crochet 32.As seen in Figure 1, the element 10 is presented with the lever 16 in the open position, so that the pins 6 and 6a are inserted respectively in the slots 21 and 28, then the lever 16 is pivoted around the axis 15 towards the closed and locked position by cooperating with the hook 32.

Lors de ce pivotement, les dents 20 entraînent en engrenant avec les dents 27, du secteur 26 de sorte que les cames 22 et 29, en basculant et en coopérant avec les tétons 6 et 6a, commandent l'engagement des parties 11 dans les compartiments 2.During this pivoting, the teeth 20 drive in meshing with the teeth 27, of the sector 26 so that the cams 22 and 29, by tilting and cooperating with the pins 6 and 6a, control the engagement of the parts 11 in the compartments 2.

Si on veut désaccoupler les éléments 1 et 10, on procède de la manière inverse.If we want to decouple elements 1 and 10, we proceed in the opposite way.

Dans le mode de réalisation décrit, le levier 16 et les secteurs sont portés par la partie mâle 10, les tétons 6, 6a étant prévus sur la partie femelle 1; on pourrait parfaitement réaliser le dispositif d'accouplement, selon l'invention, en prévoyant le levier et le secteur sur l'élément 1, les tétons étant sur l'élément 10.In the embodiment described, the lever 16 and the sectors are carried by the male part 10, the pins 6, 6a being provided on the female part 1; one could perfectly realize the coupling device according to the invention, by providing the lever and the sector on the element 1, the pins being on the element 10.

Aux figures 3 et 4 on a représenté une variante de l'invention.Figures 3 and 4 show a variant of the invention.

Sur ces figures on a utilisé pour désigner les organes correspondants à ceux des figures précédentes, les mêmes références, mais affectées de la lettre "b".In these figures, the same references, but assigned the letter "b", have been used to designate the members corresponding to those of the preceding figures.
