Description

L'invention vise des perfectionnements aux connecteurs électriques à levier de verrouillage.The invention relates to improvements in electrical connectors with locking lever.

L'invention vise des connecteurs électriques comprenant un élément de boîtier mâle contenant une série d'organes de connexions électriques mâles ou femelles, un élément de boîtier femelle contenant une série d'organes de connexions mâles ou femelles destinés à coopérer avec les organes de connexions électriques prévus dans l'élément de boîtier mâle, l'un des éléments de boîtier comportant un axe sur lequel s'articulent les extrémités des ailes d'un étrier reliées par une âme et constituant le levier de verrouillage, lesdites ailes présentant chacune une came destinée à coopérer avec un ergot des parois correspondantes de l'autre élément de manière que le pivotement du levier dans un sens tend à engager l'élément mâle dans l'élément femelle, tandis que le pivotement dans l'autre sens tend au contraire à écarter l'un de l'autre les deux dits éléments de boîtier, des moyens de blocage étant prévus pour éviter toute ouverture intempestive du levier.The invention relates to electrical connectors comprising a male housing element containing a series of male or female electrical connection members, a female housing element containing a series of male or female connection members intended to cooperate with the connection members electric provided in the male housing element, one of the housing elements having an axis on which the ends of the wings of a stirrup are connected, connected by a core and constituting the locking lever, said wings each having a cam intended to cooperate with a lug of the corresponding walls of the other element so that the pivoting of the lever in one direction tends to engage the male element in the female element, while the pivoting in the other direction tends on the contrary to move the two so-called housing elements apart from one another, blocking means being provided to prevent any untimely opening lever.

Le brevet GB 2 179 506 décrit un tel connecteur électrique, mais dans la forme de réalisation décrite, il est prévu un crochet qui bloque le levier en position de verrouillage. Une telle disposition présente l'inconvénient que si on désire ouvrir le levier, il faut avoir recours à un outil pour dégager le crochet.GB patent 2,179,506 describes such an electrical connector, but in the embodiment described, there is provided a hook which blocks the lever in the locked position. Such an arrangement has the disadvantage that if one wishes to open the lever, it is necessary to have recourse to a tool to release the hook.

L'un des buts de la présente invention est de réaliser un connecteur du type ci-dessus dans lequel les moyens de blocage du levier peuvent être manuellement dégagés pour permettre le pivotement de celui-ci dans le sens du désaccouplement des éléments de boîtier.One of the aims of the present invention is to provide a connector of the above type in which the means for blocking the lever can be released manually to allow the latter to pivot in the direction of uncoupling of the housing elements.

Les perfectionnements, selon l'invention, visent des connecteurs électriques du type comprenant un élément de boîtier isolant mâle et un élément de boîtier isolant femelle, chacun de ces éléments comportant une série d'organes de connexions électriques mâles ou femelles destinés à coopérer avec des organes de connexions électriques de l'autre élément, l'un desdits éléments de boîtier étant pourvu d'un axe sur lequel s'articulent les extrémités des ailes d'un étrier dont les autres extrémités sont reliées par une âme et constituent le levier de verrouillage, lesdites ailes présentant chacune une came destinée à coopérer avec un ergot des parois correspondantes de l'autre élément de manière que le pivotement du levier dans un sens tende à engager l'élément mâle dans l'élément femelle, tandis que le pivotement dans le sens opposé tende à écarter l'un de l'autre les deux dits éléments, des moyens de blocage étant prévus pour caler le levier dans la position dans laquelle les deux éléments de boîtier sont assemblés, lesdits perfectionnements étant caractérisés en ce que l'élément sur lequel est articulé le levier comporte, sur sa face tournée en regard de l'âme dudit levier, au moins une patte flexible attenante par l'une des extrémités à ladite face et s'étendant sensiblement parallèlement au sens de l'engagement des deux éléments l'un sur l'autre, ladite patte flexible présentant, sur sa face tournée en regard de l'âme dudit levier, une surface convexe de manière que lorsque le levier est pivoté, l'âme de celui-ci coopère avec ladite surface convexe et fasse fléchir celle-ci, ledit élément de boîtier sur lequel est articulé le levier comportant des moyens de réception et de guidage d'une clavette mobile destinée à coopérer avec la patte flexible pour s'opposer au fléchissement de celle-ci.The improvements according to the invention relate to electrical connectors of the type comprising a male insulating housing element and a female insulating housing element, each of these elements comprising a series of male or female electrical connection members intended to cooperate with electrical connection members of the other element, one of said housing elements being provided with an axis on which the ends of the wings of a stirrup are articulated, the other ends of which are connected by a core and constitute the locking lever, said wings each having a cam intended to cooperate with a lug of the corresponding walls of the other element so that the pivoting of the lever in a direction tends to engage the male element in the female element, while that the pivoting in the opposite direction tends to separate the two said elements from one another, locking means being provided for wedging the lever in the position in which the two housing elements are assembled, said improvements being characterized in that the element on which the lever is articulated comprises, on its face facing the web of said lever, at least one flexible tab attached by the one of the ends of said face and extending substantially parallel to the direction of engagement of the two elements one on the other, said flexible tab having, on its face turned opposite the web of said lever, a surface convex so that when the lever is pivoted, the core thereof cooperates with said convex surface and causes it to flex, said housing element on which the lever is articulated comprising means for receiving and guiding a movable key intended to cooperate with the flexible tab to oppose the flexing thereof.

On réalise ainsi un moyen simple de blocage du levier dans la position de verrouillage, ce moyen pouvant aisément être dégagé si cela s'avère nécessaire.A simple means of blocking the lever in the locking position is thus produced, this means being able to be easily released if necessary.

Suivant une caractéristique constructive, l'élément sur lequel est articulé le levier comporte sur sa face tournée en regard de l'âme du levier deux pattes flexibles moulées d'une seule pièce avec ledit élément et attenante à ce dernier par une extrémité adjacente à l'extrémité dudit élément opposé à celle destinée à coopérer avec l'autre élément.According to a constructive characteristic, the element on which the lever is articulated comprises on its face turned opposite the core of the lever two flexible tabs molded in one piece with said element and adjoining the latter by an end adjacent to the end of said element opposite to that intended to cooperate with the other element.

Suivant encore une caractéristique constructive, la face de l'élément sur lequel est articulé le levier et qui comporte les deux pattes flexibles présente, disposée entre lesdites pattes flexibles, au moins une glissière sur laquelle est guidée la clavette, celle-ci présentant des saillies latérales destinées à s'insérer entre ladite face et des doigts correspondants des pattes flexibles.According to yet another constructive characteristic, the face of the element on which the lever is articulated and which comprises the two flexible legs has, arranged between said flexible legs, at least one slide on which the key is guided, the latter having projections lateral intended to be inserted between said face and corresponding fingers of the flexible legs.

Enfin suivant une dernière caractéristique particulière, la face de l'élément sur lequel est articulé le levier et qui comporte les deux pattes flexibles comporte une barrette élastique pourvue d'un verrou destiné à coopérer sélectivement avec deux logements de la clavette, l'un des logements correspondant à une position d'attente de ladite clavette et l'autre à la position de verrouillage de cette dernière.Finally according to a last particular characteristic, the face of the element on which the lever is articulated and which comprises the two flexible tabs comprises an elastic bar provided with a lock intended to cooperate selectively with two housings of the key, one of the housings corresponding to a waiting position of said key and the other to the locking position of the latter.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described in more detail with reference to a particular embodiment 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 électrique, selon l'invention.Figure 1 is an exploded perspective view of an electrical connector according to the invention.

Figure 2 est une vue en perspective de l'élément de boîtier mâle, le levier étant supposé incliné.Figure 2 is a perspective view of the male housing member, the lever being assumed to be inclined.

Figure 3, figure 4 et figure 5 sont des vues en élévation schématique montrant le verrouillage du levier.Figure 3, Figure 4 and Figure 5 are schematic elevational views showing the locking of the lever.

Figures 6 et 7 sont des vues en coupe montrant les positions de pré-verrouillage et de verrouillage de la clavette.Figures 6 and 7 are sectional views showing the pre-locking and locking positions of the key.

Figure 8 montre schématiquement les organes de contacts électriques, un organe femelle prévu dans un canal de l'élément mâle et un organe mâle prévu dans l'élément femelle.Figure 8 schematically shows the electrical contact members, a female member provided in a channel of the male element and a male member provided in the female element.

Le connecteur représenté aux figures comprend un élément de boîtier femelle 1 présentant une ouverture 2 à travers laquelle saillissent des languettes mâles 3 reliées à des conducteurs ou à des circuits électriques.The connector shown in the figures comprises a female housing element 1 having an opening 2 through which project male tabs 3 connected to conductors or to electrical circuits.

Sur deux côtés opposés, l'élément de boîtier femelle 1 comporte des ergots 4.On two opposite sides, the female housing element 1 has lugs 4.

Le connecteur est complété par un élément de boîtier mâle 6 qui comporte une série de canaux 7 contenant chacun un organe de connexion femelle 8 destiné à coopérer avec un organe mâle 3 (voir figure 8).The connector is completed by a male box element 6 which comprises a series of channels 7 each containing a female connection member 8 intended to cooperate with a male member 3 (see FIG. 8).

L'élément 6 présente une jupe 10 destinée à s'insérer dans l'ouverture 2 de l'élément 1 et raccordée à un corps 11 par un épaulement 12.The element 6 has a skirt 10 intended to be inserted in the opening 2 of the element 1 and connected to a body 11 by a shoulder 12.

Sur deux parois opposées du corps 11, il est prévu un axe 13 sur lequel s'articule un levier 14.On two opposite walls of the body 11, an axis 13 is provided on which a lever 14 is articulated.

Le levier 14 présente deux branches 15 présentant chacune une came 16 destinée à coopérer avec un ergot 4, les branches étant reliées par une âme 17. Le levier est réalisé en métal et les bords latéraux de l'âme sont repliés vers l'intérieur.The lever 14 has two branches 15 each having a cam 16 intended to cooperate with a lug 4, the branches being connected by a core 17. The lever is made of metal and the lateral edges of the core are folded inwards.

Le corps 6 comprend, sur une face 19, deux pattes flexibles 21 qui sont moulées d'une seule pièce avec le corps et qui sont attenantes à celui-ci par l'une de leurs extrémités adjacentes au bord du corps 11 opposé à celui voisin de la jupe 10.The body 6 comprises, on one face 19, two flexible tabs 21 which are molded in one piece with the body and which are contiguous thereto by one of their ends adjacent to the edge of the body 11 opposite to that neighboring skirt 10.

Les pattes flexibles 21, du côté opposé à la face 19, présentent une surface convexe 21a. Les pattes flexibles 21, sur les faces tournées en regard l'une de l'autre, comportent chacune un doigt 22.The flexible tabs 21, on the side opposite to the face 19, have a convex surface 21 a . The flexible tabs 21, on the faces facing each other, each have a finger 22.

La face 19, entre les pattes flexibles 21, présente deux glissières en forme de queue d'aronde 24 entre lesquelles s'étend une barrette élastique 25 présentant, au voisinage de son extrémité libre, un verrou 26 qui du côté des glissières présente un abrupt 26a et, du côté opposé, une rampe inclinée 26b. Sur la face 19, il est également prévu deux butées 40.The face 19, between the flexible legs 21, has two slides in the form of a dovetail 24 between which extends an elastic bar 25 having, in the vicinity of its free end, a latch 26 which on the side of the slides has a steep 26 a and, on the opposite side, an inclined ramp 26 b . On the face 19, two stops 40 are also provided.

Sur les glissières 24 sont engagées des rainures 28 d'une clavette 29 présentant latéralement des saillies 30. La clavette 29 est pourvue de deux logements 31 et 32 ayant des formes correspondant au verrou 26 et qui peuvent sélectivement coopérer avec celui-ci (voir figures 6 et 7).On the slides 24 are engaged grooves 28 of a key 29 having laterally protrusions 30. The key 29 is provided with two housings 31 and 32 having shapes corresponding to the lock 26 and which can selectively cooperate with it (see figures 6 and 7).

Aux figures 3, 4 et 5, on a représenté schématiquement le fonctionnement du système de verrouillage du connecteur.In Figures 3, 4 and 5, there is shown schematically the operation of the connector locking system.

Comme on le voit à la figure 3, les ergots 4 sont destinés à coopérer avec les cames 16. Lorsque le levier est déplacé dans le sens de la flèche f (voir figure 3 ), on commande l'engagement de la jupe 10 dans l'ouverture jusqu'à ce que les ergots s'insèrent dans les extrémités des cames 16 qui présentent un cran 16a correspondant à la position extrême.As seen in Figure 3, the pins 4 are intended to cooperate with the cams 16. When the lever is moved in the direction of the arrow f (see Figure 3), the skirt 10 is engaged in the opening until the pins are inserted into the ends of the cams 16 which have a notch 16 a corresponding to the extreme position.

Durant ce basculement du levier 14, la surface interne de l'âme 17 porte contre les surfaces convexes 21a des pattes flexibles 21 et les font ployer (voir fig.4).During this tilting of the lever 14, the internal surface of the core 17 bears against the convex surfaces 21 has flexible tabs 21 and cause them to bend (see fig. 4).

Lorsque le levier 14 arrive en fin de course, les pattes flexibles 21 reviennent dans leur position initiale (voir fig.5). Si on pousse la clavette dans le sens de la flèche (fig. 5), le verrou 2 6 échappe le logement 31 et vient se placer dans le logement 32. Dans cette position, les saillies 30 viennent s'insérer sous les doigts 22 et les pattes flexibles 21 ne peuvent plus être pliées de sorte que le levier 14 ne peut plus être ramené dans la position déverrouillée. Le coulissement de la clavette 29 vers cette position de verrouillage est limité par les butées 40. Dans cette position, les organes de contacts électriques 3 sont insérés dans les organes 8.When the lever 14 reaches the end of the stroke, the flexible tabs 21 return to their initial position (see fig. 5). If the key is pushed in the direction of the arrow (fig. 5), the lock 2 6 escapes the housing 31 and is placed in the housing 32. In this position, the projections 30 are inserted under the fingers 22 and the flexible tabs 21 can no longer be folded so that the lever 14 can no longer be brought back to the unlocked position. The sliding of the key 29 towards this locking position is limited by the stops 40. In this position, the electrical contact members 3 are inserted into the members 8.

Pour procéder au deverrouillage, il suffit d'appuyer sur la barrette 25 pour dégager le verrou 26 du logement 32 et de faire coulisser la clavette 29 dans le sens de la flèche (fig. 7) afin de ramener le verrou 2 6 dans le logement 31 (voir fig. 6).To unlock, simply press the bar 25 to release the lock 26 from the housing 32 and slide the key 29 in the direction of the arrow (fig. 7) to bring the lock 2 6 in the housing 31 (see fig. 6).

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and shown. Many detailed modifications can be made without departing from the scope of the invention.
