La présente invention concerne un dispositif de verrouillage d'un connecteur comprenant un premier élément et un second élément l'un portant des contacts d'un premier type coopèrant avec des contacts d'un deuxième type porté par l'autre, la connexion se faisant par rapprochement d'une première face d'un élément avec une première face de l'autre élément. Généralement une partie d'un connecteur comprend une pluralité de contacts mâles coopérant avec des contacts femelles de l'autre partie. Si l'une des parties du connecteur est généralement fixée (sur le fond d'une baie par exemple), l'autre partie n'est maintenue que par la coopération des contacts. Cette deuxième partie qui subit le poids du câble auquel elle est reliée, peut se désolidariser de la première, soit à la suite d'un choc, soit parce que l'embrochage a été incorrect.The present invention relates to a connector locking device comprising a first element and a second element, one carrying contacts of a first type cooperating with contacts of a second type carried by the other, the connection being made. by bringing a first face of an element closer to a first face of the other element. Generally a part of a connector comprises a plurality of male contacts cooperating with female contacts of the other part. If one part of the connector is generally fixed (on the bottom of a bay for example), the other part is only held by the cooperation of the contacts. This second part, which undergoes the weight of the cable to which it is connected, can separate from the first, either following a shock, or because the racking-in has been incorrect.

Un but de l'invention est de réaliser un dispositif de verrouillage empêchant l'ouverture inopinée du connecteur, et assurant un parfait enclenchement.An object of the invention is to provide a locking device preventing the connector from being opened unexpectedly, and ensuring perfect engagement.

Un autre but de l'invention est de réaliser un dispositif de verrouillage qui, outre son rôle de blocage des éléments du connecteur, joue également le rôle de détrompeur, de manière à éviter que les éléments du connecteur, soient reliés de manière erronée.Another object of the invention is to provide a locking device which, in addition to its role of blocking the elements of the connector, also plays the role of a key, so as to prevent the elements of the connector from being connected in a wrong way.

L'invention a pour objet un dispositif de verrouillage d'un connecteur comprenant un premier élément et un second élément, l'un portant des contacts d'un premier type coopèrant avec des contacts d'un deuxième type porté par l'autre, la connexion se faisant par rapprochement d'une première face d'un élément avec une seconde face de l'autre élément, caractérisé par le fait que le premier élément comporte une première pièce munie d'organes crochus s'étendant perpendiculairement à deux arêtes de la première face vers l'extérieur de l'élément, ladite pièce pouvant se déplacer par rapport au premier élément parallèlement auxdites arêtes et étant rappelée en position fixe par un ressort, le second élément comportant une seconde pièce, fixe par rapport au second élément, disposée au voisinage de la seconde face, et portant des ouvertures de forme complémentaire de celle des organes crochus,The invention relates to a connector locking device comprising a first element and a second element, one carrying contacts of a first type cooperating with contacts of a second type carried by the other, the connection being made by bringing a first face of an element with a second face of the other element, characterized in that the first element comprises a first part provided with hooked members extending perpendicularly to two edges of the first face towards the outside of the element, said part being able to move relative to the first element parallel to said edges and being returned to a fixed position by a spring, the second element comprising a second part, fixed relative to the second element, arranged in the vicinity of the second face, and carrying openings of a shape complementary to that of the hooked organs,

L'invention sera bien comprise par la description donnée ci-après d'un mode préféré de réalisation de l'invention en regard du dessin annexé dans lequel :

  • La figure 1 montre en vue éclatée un connecteur muni du dispositif de verrouillage de l'invention.
  • Les figures 2a et 2b illustrent l'opération de connexion et de verrouillage.
The invention will be better understood from the description given below of a preferred embodiment of the invention with regard to the attached drawing in which:
  • Figure 1 shows an exploded view of a connector provided with the locking device of the invention.
  • Figures 2a and 2b illustrate the connection and locking operation.

La figure 1 représente, en vue éclatée les divers éléments d'un connecteur et de l'organe de verrouillage de l'invention.Figure 1 shows, in exploded view the various elements of a connector and the locking member of the invention.

L'exemple est celui d'un connecteur dans lequel un des éléments du connecteur, ici l'élément reférencé 1 est fixé sur une baie 2.The example is that of a connector in which one of the elements of the connector, here the element referenced 1 is fixed on a bay 2.

La baie est une carte de circuit imprimé. La carte peut être horizontale ou verticale. Des broches 3 traversent la carte et l'élément de connecteur 1 par des trous 5. Cet élément 1 du connecteur, ayant la forme d'une boîte à l'intérieur de laquelle saillent les broches 3, est destiné à être relié à un second élément 6, portant des cavités 7 en correspondance avec les broches 3 ; au fond de ces cavités sont placées des broches 8, dont des extrémités 8a coopèrent avec les broches 3 pour réaliser le contact électrique et dont les autres extrémités sont reliées à des fils 9 réunis pour former un câble 9a qui sort de l'élément 6.The bay is a printed circuit board. The map can be horizontal or vertical. Pins 3 pass through the card and the connector element 1 through holes 5. This connector element 1, having the shape of a box inside which the pins 3 protrude, is intended to be connected to a second element 6, carrying cavities 7 in correspondence with pins 3; at the bottom of these cavities are placed pins 8, the ends of which 8a cooperate with the pins 3 to make the electrical contact and the other ends of which are connected to wires 9 joined together to form a cable 9a which leaves the element 6.

Pour verrouiller ce connecteur, on munit ses éléments 1 et 6 respectivement d'un premier et d'un second organe de verrouillage.To lock this connector, its elements 1 and 6 are provided with a first and a second locking member respectively.

Une première pièce de verrouillage 10 est une pièce métallique, qui est montée autour de l'élément 1 et qui comprend des glissières telles que 11a à 11d pouvant coulisser dans des rainures 12a à 12d pratiquées dans l'élément 1. Des organes crochus tels que 13 s'étendent parallèlement à deux grandes faces 14a et 14b de l'élément 1 et s'étendent au delà des arêtes de cet élément.A first locking piece 10 is a metal piece, which is mounted around the element 1 and which includes slides such as 11a to 11d which can slide in grooves 12a to 12d formed in the element 1. Hooked members such as 13 extend parallel to two large faces 14a and 14b of the element 1 and extend beyond the edges of this element.

Un ressort, formé d'une lame métallique élastique 15, s'appuie d'une part contre une extrémité de l'élément 1, d'autre part contre un repli 16 de la pièce 10.A spring formed from an elastic metal blade 15 rests on the one hand against one end of the element 1, on the other hand against a fold 16 of the part 10.

Il est maintenu en place par des pattes 15a et 15b qui s'appuient sur les glissières 11a et 11b respectivement.It is held in place by lugs 15a and 15b which rest on the slides 11a and 11b respectively.

Une seconde pièce de verrouillage 20 entoure l'élément 6 de connecteur, au voisinage de la face en vis-à-vis de l'élément 1. Cette pièce est fixée sur l'élément 6 au moyen de vis 21a et 21b, traversant des orifices 22a et 22b de pattes transversales 23a et 23b de la pièce. Les pattes reposent sur des épaulements 24a et 24b de l'élément 6, munis de trous 25 a et 25b pour recevoir les vis 21a et 21b.A second locking part 20 surrounds the connector element 6, in the vicinity of the face facing the element 1. This part is fixed to the element 6 by means of screws 21a and 21b, passing through holes 22a and 22b of transverse lugs 23a and 23b of the room. The legs rest on shoulders 24a and 24b of the element 6, provided with holes 25a and 25b to receive the screws 21a and 21b.

La pièce porte latéralement des encoches 26 destinées a coopérer avec les organes crochus 13. La dimension d de l'ouverture 26a de l'encoche est juste un peu supérieure à la longueur du crochet comptée de la pointe 13a au talon 13b, de manière à permettre l'engagement des crochets dans les encoches.The part carries laterally notches 26 intended to cooperate with the hooked members 13. The dimension d of the opening 26a of the notch is just slightly greater than the length of the hook counted from the tip 13a to the heel 13b, so as to allow the hooks to be engaged in the notches.

La mise en oeuvre du connecteur est illustré dans les figures 2a et 2b.The implementation of the connector is illustrated in Figures 2a and 2b.

Pour relier les deux éléments du connecteur 1 et 6, on appuie sur la pièce de verrouillage 10 (flèche F figure 2a) ; de la sorte lorsque les cavités 7 viennent en face des broches 3, les organes crochus 13 sont en faces des encoches 26 et peuvent y pénétrer.To connect the two elements of connector 1 and 6, the locking piece 10 is pressed (arrow F in figure 2a); in this way when the cavities 7 come opposite the pins 3, the hooked members 13 are opposite the notches 26 and can penetrate therein.

On rapproche les deux éléments du connecteur (flèche F3), puis (figure 2b) on relâche la pression sur la pièce de verrouillage 10. Chaque crochet des organes crochus rentre alors dans la partie centrale de l'encoche correspondante.The two elements of the connector are brought together (arrow F3), then (FIG. 2b) the pressure is released on the locking piece 10. Each hook of the hooked members then enters the central part of the corresponding notch.

On notera que la forme des crochets permet une introduction et un verrouillage automatique.It will be noted that the shape of the hooks allows automatic introduction and locking.

Le verrouillage est effectué.Locking is performed.

On remarquera que la disposition des crochets et des encoches assure une sécurité supplémentaire puisqu'il est impossible de connecter à l'envers les deux éléments du connecteur.It will be noted that the arrangement of the hooks and the notches provides additional security since it is impossible to connect the two elements of the connector upside down.

Dans l'exemple décrit c'est l'organe porteur de crochets qui est mobile en translation ; bien entendu l'organe porteur d'encoches peut être mobile, l'organe porteur de crochets étant alors fixe.In the example described, it is the hook-carrying member which is movable in translation; of course the notch-carrying member can be movable, the hook-carrying member then being fixed.
