Description

L'invention vise des boîtiers de connexions électriques.The invention relates to electrical connection boxes.

L'invention se rapporte à des boîtiers de con­nexions électriques comprenant un élément de boîtier mâle comportant une série de canaux destinés à recevoir chacun un organe de connexion électrique mâle ou femelle et des­tiné à s'insérer dans la jupe d'un élément de boîtier femel­le présentant une série de canaux destinés à recevoir cha­cun un organe de connexion électrique complémentaire de ceux de l'élément de boîtier mâle.The invention relates to electrical connection boxes comprising a male box element comprising a series of channels intended to each receive a male or female electrical connection member and intended to be inserted into the skirt of a female box element having a series of channels intended to each receive an electrical connection member complementary to those of the male housing element.

De tels éléments de boîtier sont très connus et très utilisés dans de nombreux domaines, industries auto­mobiles, aviation etc...Such housing elements are very well known and widely used in many fields, automobile industries, aviation, etc.

Lorsque les deux éléments de boîtier ne sont pas parfaitement engagés l'un dans l'autre, la liaison élec­trique est défectueuse. La demanderesse dans son brevet français No 2 576. 155 du 14 Janvier 1985 et dans sa demande de brevet français no 88 12 265 du 20 Septembre 1988 a proposé de réaliser des boîtiers de connexions électriques dans lesquels l'élément de boîtier mâle comporte des moyens de verrouillage constitués par une barrette élastique, pourvue d'une saillie avec deux rampes inclinées reliées par une arête, tandis que la jupe comporte une protubérance desti­née à coopérer avec la saillie de sorte qu'au début de l'in­sertion il faut un effort relativement important pour que la protubérance franchisse la première rampe moyennant une déformation élastique de la barrette élastique, tandis que lorsque l'arête est franchie la protubérance et la seconde rampe tendent à faciliter l'engagement de l'élément mâle dans la jupe de l'élément femelle jusqu'au verrouillage des deux éléments l'un par rapport à l'autre.When the two housing elements are not perfectly engaged with each other, the electrical connection is defective. The Applicant in its French patent No. 2 576 155 of January 14, 1985 and in French patent application No. 88 12 265 of September 20, 1988 has proposed to produce packages with electrical connections in which the male housing element comprises locking means constituted by an elastic bar, provided with a projection with two inclined ramps connected by an edge, while the skirt has a protuberance intended to cooperate with the projection so that at the start of insertion a relatively large effort so that the protuberance crosses the first ramp by means of an elastic deformation of the elastic strip, while when the edge is crossed the protuberance and the second ramp tend to facilitate the engagement of the male element in the skirt of the 'female element until the two elements are locked relative to each other.

Grâce à une telle disposition si l'élément de boîtier mâle est mal engagé dans la jupe, la première ram­pe et la protubérance, grâce à l'action élastique de la barrette, tendent à séparer les deux éléments de boîtier, ce qui évite les mauvais contacts.Thanks to such an arrangement if the male housing element is improperly engaged in the skirt, the first ramp and the protuberance, thanks to the elastic action of the bar, tend to separate the two housing elements, which avoids bad contacts.

On a toutefois constaté que cette action d'écar­tement des éléments de boîtier lorsqu'ils sont insuffisam­ment engagés n'était pas assez puissante notamment lors­qu'il s'agit de boîtier de très petites dimensions.However, it has been found that this action of spacing the housing elements when they are insufficiently engaged was not powerful enough, especially when it is a case of very small dimensions.

L'un des buts de la présente invention est de remédier à ces inconvénients.One of the aims of the present invention is to remedy these drawbacks.

L'invention vise des boîtiers de connexions électriques du type comprenant un élément de boîtier mâle, un élément de boîtier femelle avec une jupe destinée à re­cevoir l'élément de boîtier mâle, chaque élément de boîtier étant pourvu d'une série de canaux, les canaux de l'un des éléments de boîtier étant destinés à recevoir des organes de connexions électriques mâles et les canaux de l'autre élément de boîtier des organes de connexions électriques femelles complémentaires, l'élément de boîtier mâle compor­tant un organe de verrouillage formé d'une barrette élas­tique dont une extrémité tournée du côté de la partie de l'élément dudit boîtier mâle destinée à s'insérer dans la jupe est solidaire dudit élément de boîtier mâle, tandis que l'autre extrémité est terminée par un organe de préhen­sion, ladite barrette élastique comportant des moyens con­jugués avec des moyens prévus sur la jupe afin d'assurer le verrouillage des éléments de boîtier lorsqu'ils sont insérés l'un dans l'autre, ladite jupe étant pourvue d'une protubérance destinée à coopérer avec une saillie reliée à la barrette élastique et présentant deux rampes inclinées reliées par une arête et disposée de manière que lorsque l'élément de boîtier mâle est insuffisamment engagé dans la jupe l'action conjuguée de la première rampe de la pro­tubérance et de la barrette élastique tende à écarter l'un de l'autre les deux éléments tandis que lorsque la protubé­rance a franchi l'arête les éléments de boîtier tendent à s'insérer l'un dans l'autre vers la fonction de verrouil­lage, lesdits perfectionnements étant caractérisés en ce que l'un des éléments de boîtier comporte un dispositif antagoniste comprenant deux nervures présentant des prolon­ gements libres terminés par des doigts recourbés dont les extrémités se font vis à vis, tandis que l'autre élément de boîtier comporte un bossage présentant des butées situées sur le trajet des doigts lors du montage des éléments de boîtiers, la position des butées étant telle que, tant que la protubérance n'a pas franchi l'arête de la saillie, les doigts s'arc-boutent contre les butées, tandis qu'ils fléchissent pour échapper lesdites butées dès que l'arête a été franchie par la protubérance.The invention relates to electrical connection boxes of the type comprising a male box element, a female box element with a skirt intended to receive the male box element, each box element being provided with a series of channels, the channels of one of the housing elements being intended to receive male electrical connection members and the channels of the other housing element of complementary female electrical connection members, the male housing element comprising a locking member formed by a resilient bar, one end of which is turned towards the side of the part of the element of said male casing intended to be inserted into the skirt, is integral with said male casing element, while the other end is terminated by a gripping member, said elastic bar comprising means combined with means provided on the skirt in order to ensure the locking of the elements s of housing when they are inserted one inside the other, said skirt being provided with a protuberance intended to cooperate with a projection connected to the elastic bar and having two inclined ramps connected by an edge and arranged so that when the male housing element is insufficiently engaged in the skirt the combined action of the first ramp of the protuberance and of the elastic bar tends to separate the two elements from one another while when the protuberance has crossed the edges the housing elements tend to fit into one another towards the locking function, said improvements being characterized in that one of the housing elements comprises an antagonistic device comprising two ribs having prolons free bearings terminated by curved fingers, the ends of which face each other, while the other housing element has a boss having stops situated in the path of the fingers during assembly of the housing elements, the position of the stops being such that, as long as the protuberance has not crossed the edge of the projection, the fingers are braced against the stops, while they flex to escape said stops as soon as the edge has been crossed by the protuberance.

Grâce à une telle caractéristique, l'action de répulsion de l'élément de boîtier mâle est renforcée lorsque son engagement dans la jupe du boîtier femelle est insuffisante et le désaccouplement ne nécessite aucun ef­fort supplémentaire.Thanks to such a characteristic, the repelling action of the male housing element is reinforced when its engagement in the skirt of the female housing is insufficient and the uncoupling does not require any additional effort.

Suivant un détail constructif, le dispositif antagoniste est moulé d'une seule pièce avec l'élément de boîtier mâle.According to a constructive detail, the opposing device is molded in one piece with the male housing element.

Suivant une variante de réalisation, le disposi­tif antagoniste est constitué d'un élément indépendant et l'élément de boîtier correspondant comporte des moyens pour sa fixation.According to an alternative embodiment, the opposing device consists of an independent element and the corresponding housing element comprises means for fixing it.

Suivant un autre détail constructif, le dispo­sitif antagoniste est porté par l'élément de boîtier mâle le bossage étant porté par la surface interne de la jupe.According to another constructive detail, the opposing device is carried by the male box element, the boss being carried by the internal surface of the skirt.

Le dispositif antagoniste peut être porté par l'élément de boîtier femelle et le bossage par l'élément de boîtier mâle.The opposing device can be carried by the female housing element and the boss by the male housing element.

Enfin, le bossage présente deux rampes desti­nées à coopérer l'une avec l'extrémité libre d'un doigt et l'autre avec l'extrémité libre de l'autre doigt et ter­minées par les butées.Finally, the boss has two ramps intended to cooperate, one with the free end of a finger and the other with the free end of the other finger and terminated by the stops.

L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particulier donnés à titre d'exemple seulement et représen­tés aux dessins annexés, dans lesquels :

  • Figure 1 est une vue en perspective d'un boîtier perfectionné, selon l'invention.
  • Figure 2 à figure 9 sont des vues schématiques montrant le fonctionnement de l'invention.
  • Figure 10 est une vue en perspective d'une va­riante de réalisation.
  • Figure 11 est une vue en perspective d'encore une autre forme de réalisation de l'invention.
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 is a perspective view of an improved housing, according to the invention.
  • Figure 2 to Figure 9 are schematic views showing the operation of the invention.
  • Figure 10 is a perspective view of an alternative embodiment.
  • Figure 11 is a perspective view of yet another embodiment of the invention.

Aux figures 1 à 9 on a représenté un boîtier de connexions électriques comprenant un élément de boîtier mâle 1 et un élément de boîtier femelle 2 pourvu sur sa face antérieure d'une jupe 3 destinée à recevoir l'élément mâle 1 et d'une série de canaux 4 dans lesquels sont logés des organes de connexions électriques mâles 5 reliés à des conducteurs 6 ét faisant saillie dans la jupe 3.In Figures 1 to 9 there is shown an electrical connection box comprising a male box element 1 and a female box element 2 provided on its front face with a skirt 3 intended to receive the male element 1 and a series channels 4 in which are housed male electrical connection members 5 connected to conductors 6 and protruding into the skirt 3.

L'élément de boîtier mâle 1 présente une série de canaux 8 destinés à recevoir chacun un organe de connexions électriques femelle 9 relié à un conducteur 10.The male box element 1 has a series of channels 8 each intended to receive a female electrical connection member 9 connected to a conductor 10.

L'élément 1 comporte un moyen de verrouillage 11 comprenant deux barrettes élastiques 12 solidaires par une extrémité de l'extrémité antérieure de l'élément 1 et dont l'autre extrémité est reliée par un organe de préhen­sion.The element 1 comprises a locking means 11 comprising two elastic bars 12 secured by one end of the front end of the element 1 and the other end of which is connected by a gripping member.

Les faces des barrettes élastiques 12 qui se font vis à vis sont solidaires, chacune d'une saillie 14, chaque saillie présentant une rampe 14a, une arête 14b et une rampe 14c.The faces of the elastic bars 12 which face each other are integral, each with a projection 14, each projection having a ramp 14a, an edge 14b and a ramp 14c.

Les faces supérieures des barrettes élastiques 12 comportent des ergots 15 destinés à coopérer avec des trous 16 d'un côté 3a de la jupe 3 afin d'assurer le bloca­ge des deux éléments de boîtiers 1 et 2 lorsqu'ils sont engagés l'un dans l'autre.The upper faces of the elastic bars 12 comprise lugs 15 intended to cooperate with holes 16 on one side 3a of the skirt 3 in order to ensure the blocking of the two housing elements 1 and 2 when they are engaged one in the other.

Le côté 3a de la jupe 3 comporte une protubé­rance 20 qui présente du côté de l'ouverture de la jupe 3 une face plane 20a prolongée par deux faces 20b qui se rejoignent du côté des canaux 4, ladite protubérance affec­tant ainsi la forme d'un coin.The side 3a of the skirt 3 has a protuberance 20 which has, on the side of the opening of the skirt 3, a flat face 20a extended by two faces 20b which meet on the side of the channels 4, said protuberance thus affecting the shape of a corner.

La largeur de la face 20a est telle que lorsque l'élément 1 est engagé dans la jupe 3 la protubérance 20 peut s'insérer entre les barrettes 12 mais, que, lorsqu'elle rencontre les saillies 14 lesdites barrettes 12 doivent fléchir jusqu'à ce que les arêtes, 14b soient franchies par ladite protubérance 20, après quoi les barrettes 12 revien­nent dans leur position initiale et tendent ainsi grâce aux rampes 14c à favoriser l'engagement de l'élément de boîtier 1 dans la jupe 3. Simultanément par un fléchisse­ment vers le bas des barrettes 12 les ergots 15 pénètrent dans les trous 16, lesdites barrettes 12 reprenant leur position initiale. Ainsi les éléments de boîtier 1 et 2 sont verrouillés.The width of the face 20a is such that when the element 1 is engaged in the skirt 3 the protuberance 20 can be inserted between the bars 12 but, that, when it meets the projections 14, said bars 12 must bend until that the edges, 14b are crossed by said protuberance 20, after which the bars 12 return to their initial position and thus tend through the ramps 14c to promote the engagement of the housing element 1 in the skirt 3. Simultaneously by a downward bending of the bars 12 the pins 15 penetrate the holes 16, said bars 12 returning to their initial position. Thus the housing elements 1 and 2 are locked.

Grâce à cette disposition, si l'élément de boî­tier mâle 1 n'est pas suffisamment engagé dans la jupe 3 les rampes 14a en coopérant avec la protubérance 20 tendent à écarter les éléments de boîtier l'un de l'autre et on évite ainsi des liaisons électriques imparfaites entre les organes 5 et 9.Thanks to this arrangement, if the male housing element 1 is not sufficiently engaged in the skirt 3 the ramps 14a by cooperating with the protuberance 20 tend to separate the housing elements from one another and this is avoided imperfect electrical connections between members 5 and 9.

Dans certains cas, l'action des saillies 14 peut être insuffisante. Pour renforcer l'action élastique de rejet d'un élément de boîtier par rapport à l'autre lorsque la protubérance 20 n'a pas franchi les arêtes 14b, il est prévu sur chacun des deux petits côtés 26 de l'élément de boîtier 1 un dispositif antagoniste 25.In some cases, the action of the projections 14 may be insufficient. To reinforce the elastic rejection action of one housing element relative to the other when the protuberance 20 has not crossed the edges 14b, it is provided on each of the two short sides 26 of the housing element 1 an opposing device 25.

Chaque dispositif antagoniste 25 comprend une plaquette 28 qui s'insère dans des glissières 27 des petits côtés 26, lesdites glissières comportant des butées 29 et les petits côtés étant pourvus de tétons 30 destinés à s'en­gager dans des ouvertures 31 des plaquettes 28 pour assurer le verrouillage de celles-ci.Each opposing device 25 comprises a plate 28 which is inserted in slides 27 on the short sides 26, said slides having stops 29 and the short sides being provided with pins 30 intended to engage in openings 31 of the plates 28 to ensure locking them.

Les plaquettes 28 comportent deux nervures 32 et 33. La nervure 32 présente un prolongement libre 32a terminé par un doigt recourbé 32b, tandis que la languette 33 est formée d'un prolongement libre 33a terminé par un doigt recourbé 33b s'étendant en direction de l'extrémité libre du doigt 32b.The plates 28 have two ribs 32 and 33. The rib 32 has a free extension 32a terminated by a curved finger 32b, while the tongue 33 is formed by a free extension 33a terminated by a curved finger 33b extending in the direction of the free end of finger 32b.

Les petits côtés internes de la jupe 3 sont pourvus chacun d'un bossage 40 présentant vers l'ouvertu­re de la jupe une partie allant en s'amincissant avec deux rampes 40a et 40b, deux butées 40c et 40d et une partie arrondie 40e tournée vers les canaux 4.The short internal sides of the skirt 3 are each provided with a boss 40 having, towards the opening of the skirt, a part which tapers with two ramps 40a and 40b, two stops 40c and 40d and a rounded part 40e turned towards channels 4.

Les figurers 2 à 9 imagent le fonctionnement de l'invention, la figure 2 montre la position des doigts 32b, 33b par rapport aux bossages 40, lors du début de l'in­troduction de l'élément mâle de boîtier 1 dans la jupe 3, la figure 3 montrant la position correspondante de la pro­tubérance 20 entre les barrettes élastiques 12. Ainsi les figures 4 et 5, 6 et 7 et 8 et 9 sont correspondantes.The figurers 2 to 9 illustrate the operation of the invention, FIG. 2 shows the position of the fingers 32b, 33b relative to the bosses 40, at the start of the introduction of the male housing element 1 into the skirt 3, Figure 3 showing the corresponding position of the protrusion 20 between the elastic bars 12. Thus Figures 4 and 5, 6 and 7 and 8 and 9 are corresponding.

Ainsi, au début de l'engagement de l'élément de boîtier mâle 1 dans la jupe 3 la protubérance 20 porte contre les rampes 14a des saillies 14, tandis que les doigts 32b et 33b sont d'abord légèrement écartés l'un de l'autre par les rampes 40a et 40b puis viennent porter contre les butées 40c et 40d.Thus, at the start of the engagement of the male box element 1 in the skirt 3, the protuberance 20 bears against the ramps 14a of the projections 14, while the fingers 32b and 33b are first slightly separated from one 'other by the ramps 40a and 40b then come to bear against the stops 40c and 40d.

Si on continue à engager l'élément de boîtier mâle 1 dans la jupe 3 (voir figures 4 et 5) les doigts 32b et 33b s'arc-boutent en ployant élastiquement, tandis que le bossage 20 arrive au voisinage des arêtes 14b. Si l'in­sertion de l'élément 1 dans la jupe 3 est arrêté, par l'ac­tion conjuguée des rampes 14a, de l'élasticité des barrettes 12 et des doigts 32b et 33b l'élément de boîtier mâle 1 est repoussé.If one continues to engage the male housing element 1 in the skirt 3 (see FIGS. 4 and 5) the fingers 32b and 33b are braced by bending elastically, while the boss 20 arrives in the vicinity of the edges 14b. If the insertion of the element 1 in the skirt 3 is stopped, by the combined action of the ramps 14a, the elasticity of the bars 12 and of the fingers 32b and 33b the male housing element 1 is pushed back.

Si l'insertion continue les doigts 32b, 33b franchissent les bossages 40, tandis que la protubérance 20 en coopérant avec les rampes 14c tend à faciliter l'en­gagement de l'élément de boîtier mâle 1 dans la jupe 3 jus­ qu'au verrouillage obtenu par l'engagement des ergots 15 dans les trous 16.If the insertion continues, the fingers 32b, 33b pass through the bosses 40, while the protuberance 20 by cooperating with the ramps 14c tends to facilitate the engagement of the male housing element 1 in the skirt 3 jus that locking obtained by the engagement of the pins 15 in the holes 16.

Lors de la séparation des éléments de boîtier, les doigts 32b et 33b n'offre que peu de résistance puis­qu'ils peuvent aisément franchir les bossages 40.When the housing elements are separated, the fingers 32b and 33b offer little resistance since they can easily pass through the bosses 40.

Aux figures 10 et 11, on a représenté deux va­riantes de réalisation de l'invention. Dans la première variante, le boîtier comprend un élément de boîtier mâle et un élément de boîtier femelle 46 avec une jupe 47. L'élément 45 comporte des canaux 49 destinés à recevoir des organes de contacts électriques tels que l'organe 9 (voir figure 1), tandis que l'élément 46 est pourvu de canaux 48 destinés à recevoir des organes de contacts électriques tels que l'organe 5 (voir figure 1).In Figures 10 and 11, there are shown two alternative embodiments of the invention. In the first variant, the housing comprises a male housing element and a female housing element 46 with a skirt 47. The element 45 comprises channels 49 intended to receive electrical contact members such as member 9 (see figure 1), while the element 46 is provided with channels 48 intended to receive the electrical contact members such as the member 5 (see FIG. 1).

L'élément 45 est pourvu d'un organe de verrouil­lage 50 présentant une barrette élastique 53 terminée par un organe de préhension 54, la barrette étant pourvue sur ses deux faces latérales de saillies 51 présentant chacune une rampe inclinée 51a, une arête 51b et une seconde rampe 51c.The element 45 is provided with a locking member 50 having an elastic bar 53 terminated by a gripping member 54, the bar being provided on its two lateral faces with projections 51 each having an inclined ramp 51a, an edge 51b and a second ramp 51c.

En arrière des rampes 51c l'organe de verrouil­lage comporte des encoches 55 destinées à coopérer avec des protubérances 61 portées par des pattes 60 solidaires de la jupe 47.Behind the ramps 51c, the locking member includes notches 55 intended to cooperate with protuberances 61 carried by lugs 60 integral with the skirt 47.

Les rampes 51a sont prolongées par des languet­tes élastiques 59.The ramps 51a are extended by elastic tongues 59.

Lorsqu'on engage l'élément de boîtier mâle 45 dans la jupe 47, les protubérances 61 butent contre les languettes élastiques 59 puis coopèrent avec les rampes 51a pour faire ployer élastiquement la barrette 53. Si l'élé­ment 45 est insuffisamment enfoncé dans la jupe 47 les languettes élastiques 59 et les rampes 51a tendent à écarter l'un de l'autre les deux éléments de boîtier. Lorsque les protubérances 61 franchissent les arêtes 51b les rampes 51c tendent à faciliter l'engagement de l'élément mâle 45 dans la jupe 47 et lorsque lesdites protubérances 61 sont engagées dans les encochés 55 les deux éléments 45 et 46 sont verrouillés.When the male casing element 45 is engaged in the skirt 47, the protrusions 61 abut against the elastic tongues 59 then cooperate with the ramps 51a to elastically bend the bar 53. If the element 45 is insufficiently pressed into the skirt 47 the elastic tongues 59 and the ramps 51a tend to separate the two housing elements from one another. When the protrusions 61 cross the edges 51b the ramps 51c tend to facilitate the engagement of the male element 45 in the skirt 47 and when said protrusions 61 are engaged in the notches 55 the two elements 45 and 46 are locked.

Pour pouvoir séparer les deux éléments, il faut soulever par l'organe de préhension 54 la barrette 53 et lorsqu'on exerce une traction sur l'élément mâle de boî­tier 45 par rapport à l'élément femelle, les protubérances 61 passent sous les saillies 51.In order to be able to separate the two elements, the bar 53 must be lifted by the gripping member 54 and when a pull is exerted on the male housing element 45 relative to the female element, the protuberances 61 pass under the projections 51.

Sur deux petits côtés opposés 58, l'élément de boîtier mâle 45 comporte un dispositif antagoniste 65 moulé d'une seule pièce avec le corps dudit élément mâle 45.On two opposite small sides 58, the male box element 45 comprises an opposing device 65 molded in one piece with the body of said male element 45.

Chaque dispositif comprend deux nervures paral­lèles 66 et 67 pourvues respectivement de prolongements libres 66a, 67a, terminés par des doigts recourbés 66b et 67b.Each device comprises two parallel ribs 66 and 67 provided respectively with free extensions 66a, 67a, terminated by curved fingers 66b and 67b.

Sur la face interne de la jupe 47, il est pré­vu des bossages 70 correspondant aux doigts 66b, 67b, les bossages 70 présentant deux rampes 70a, 70b, deux butées 70c et 70d et une partie arrondie 70e.On the internal face of the skirt 47, bosses 70 corresponding to the fingers 66b, 67b are provided, the bosses 70 having two ramps 70a, 70b, two stops 70c and 70d and a rounded part 70e.

Le dispositif antagoniste 65 fonctionne de la même façon que celui des figures 1 à 9, les doigts 66b, 67b franchissant les butées 70c et 70d que lorsque les pro­tubérances 61 ont franchi les arêtes 51b.The opposing device 65 operates in the same way as that of FIGS. 1 to 9, the fingers 66b, 67b crossing the stops 70c and 70d only when the protuberances 61 have crossed the edges 51b.

Le boîtier de la figure 11 comprend un élément de boîtier mâle 80, un élément de boîtier femelle 81 avec une jupe 88 pourvue de protubérances 83 destinées à coopé­rer avec un organe de verrouillage 82 du même type que celui de la figure 10.The box of FIG. 11 comprises a male box element 80, a female box element 81 with a skirt 88 provided with protuberances 83 intended to cooperate with a locking member 82 of the same type as that of FIG. 10.

L'élément de boîtier femelle 81, extérieurement à la jupe 88 comprend un dispositif antagoniste 84 avec deux nervures 85 et 86 présentant des prolongements libres respectivement 85a et 86a terminés par des doigts recour­bés 85b, 86b.The female housing element 81, exterior to the skirt 88 comprises an antagonist device 84 with two ribs 85 and 86 having free extensions 85a and 86a respectively terminated by curved fingers 85b, 86b.

Une face extérieure de l'élément de boîtier mâle 80 comporte un bossage 87 destiné à coopérer avec le dispositif 84 et présentant deux rampes 87a et 87b, deux butées 87c et 87d et une partie arrondie 87e.An outer face of the male box element 80 has a boss 87 intended to cooperate with the device 84 and having two ramps 87a and 87b, two stops 87c and 87d and a rounded part 87e.

Le dispositif 84 fonctionne de la même façon que celui de la figure 10.The device 84 operates in the same way as that of FIG. 10.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et représentés. 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 embodiments which have just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
