Les dessins annexés illustrent l’invention :The accompanying drawings illustrate the invention:
La
Le premier raccord 1 et le second raccord 2 comportent chacun une seconde partie respectivement 12 et 22 adaptées pour être solidarisées respectivement à une extrémité libre d’un premier conduit de fluide et à une extrémité libre d’un second conduit de fluide.The first connector 1 and the second connector 2 each comprise a second part respectively 12 and 22 adapted to be secured respectively to a free end of a first fluid conduit and to a free end of a second fluid conduit.
La première partie mâle 11 du premier raccord 1 comporte une surface cylindrique 13 et la première partie femelle 21 du second raccord 2 comporte un joint d’étanchéité 23 qui sont positionnés de telle sorte que la partie cylindrique 13 de la première partie mâle 11 est en appui contre le joint d’étanchéité 23 de la première partie femelle 21 dans cette position assemblée, assurant l’étanchéité de l’assemblage entre le premier raccord 1 et le second raccord 2.The first male part 11 of the first coupling 1 comprises a cylindrical surface 13 and the first female part 21 of the second coupling 2 comprises a seal 23 which are positioned such that the cylindrical part 13 of the first male part 11 is in bearing against the seal 23 of the first female part 21 in this assembled position, ensuring the sealing of the assembly between the first connector 1 and the second connector 2.
Avant l’assemblage entre le premier raccord 1 et le second raccord 2, la surface cylindrique 13 de la première partie mâle 11 du premier raccord 1 doit être protégée pour ne pas être rayée ce qui dégraderait l’étanchéité de cet assemblage.Before assembly between the first connector 1 and the second connector 2, the cylindrical surface 13 of the first male part 11 of the first connector 1 must be protected so as not to be scratched, which would degrade the tightness of this assembly.
Pour ce faire, la surface cylindrique 13 de la première partie mâle 11 du premier raccord 1 est recouverte par une paroi de protection 3 qui est adaptée pour être rabattue lorsque la première partie mâle 11 du premier raccord 1 est logée dans la première partie femelle 21 du second raccord 2.To do this, the cylindrical surface 13 of the first male part 11 of the first connector 1 is covered by a protective wall 3 which is adapted to be folded down when the first male part 11 of the first connector 1 is housed in the first female part 21 of the second connection 2.
La paroi de protection 3 présente une forme en soufflets 31, faisant que lorsque la première partie mâle 11 du premier raccord 1 est logée dans la première partie femelle 21 du second raccord 2, une extrémité recourbée 32 des soufflets 31 vient en appui contre le joint d’étanchéité 23 de la première partie femelle 21 du second raccord 2 et les soufflets 31 sont comprimés, libérant la surface cylindrique 13 de la première partie mâle 11 du premier raccord 1 pour que le joint d’étanchéité 23 de la première partie femelle 21 du second raccord 2 puisse former un assemblage étanche.The protective wall 3 has the shape of bellows 31, so that when the first male part 11 of the first connector 1 is housed in the first female part 21 of the second connector 2, a curved end 32 of the bellows 31 comes to rest against the joint seal 23 of the first female part 21 of the second connector 2 and the bellows 31 are compressed, releasing the cylindrical surface 13 of the first male part 11 of the first connector 1 so that the seal 23 of the first female part 21 of the second connector 2 can form a sealed assembly.
De tels soufflets 31 sont généralement formés dans une matière plastique élastique, permettant un retour dans la position de recouvrement de la surface cylindrique 13 de la première partie mâle 11 du premier raccord 1 une fois la partie mâle 11 du premier raccord 1 de retirée de la première partie femelle 21 du second raccord 2.Such bellows 31 are generally formed in an elastic plastic material, allowing a return to the position of covering the cylindrical surface 13 of the first male part 11 of the first connector 1 once the male part 11 of the first connector 1 has been removed from the first female part 21 of the second connector 2.
La première partie femelle 21 du second raccord 2 comporte une cloison de protection 4 qui ferme l’accès à l’intérieur de cette partie femelle 21 du second raccord 2 et qui est adaptée pour s’ouvrir lorsque la première partie mâle 11 du premier raccord 1 est logée dans la première partie femelle 21 du second raccord 2.The first female part 21 of the second connector 2 comprises a protective partition 4 which closes access to the interior of this female part 21 of the second connector 2 and which is adapted to open when the first male part 11 of the first connector 1 is housed in the first female part 21 of the second connector 2.
Le joint d’étanchéité 23 qui est dans cet exemple de mode de réalisation un joint torique, est lubrifié pour faciliter l’assemblage de cet ensemble de deux raccords.The seal 23 which is in this example embodiment an O-ring, is lubricated to facilitate the assembly of this set of two fittings.
La cloison de protection 4 participe au maintien de la lubrification sur le joint d’étanchéité 23.The protective partition 4 participates in maintaining the lubrication on the seal 23.
Comme plus particulièrement visible sur la
La partie centrale 42 de la cloison de protection 4 présente des découpes concentriques 44, se prolongeant du bord périphérique 41 jusqu’au centre de la cloison de protection 4, en formant des battants triangulaires 43.The central part 42 of the protective partition 4 has concentric cutouts 44, extending from the peripheral edge 41 to the center of the protective partition 4, forming triangular leaves 43.
La cloison de protection 4 est formée dans une matière plastique élastique, permettant aux battants 43 de se rabattre le long de la paroi intérieure de la partie femelle 21 du second raccord 2 lors de l’assemblage avec la partie mâle 11 du premier raccord 1 et de revenir en position initiale une fois la partie mâle 11 du premier raccord 1 de retirée.The protective partition 4 is formed in an elastic plastic material, allowing the flaps 43 to fold down along the interior wall of the female part 21 of the second connector 2 during assembly with the male part 11 of the first connector 1 and to return to the initial position once the male part 11 of the first connector 1 is removed.
Sur la
Sur cette figure est plus particulièrement visible le positionnement comprimé des soufflets 31 de la paroi de protection 3 et la position rabattue des battants 43 de la cloison de protection 4.In this figure is more particularly visible the compressed positioning of the bellows 31 of the protective wall 3 and the folded position of the leaves 43 of the protective partition 4.
Un tel montage étanche se fait par un unique mouvement de translation, dont l’effort à fournir est réduite par la lubrification du joint d’étanchéité 3.Such a sealed assembly is done by a single translational movement, the effort required of which is reduced by the lubrication of the seal 3.
Au montage, les battants 43 sont pliés contre la paroi intérieure du second raccord 2 formant en même temps une surface de guidage de la partie mâle 11 du premier raccord 1.On assembly, the leaves 43 are folded against the inner wall of the second connector 2 forming at the same time a guide surface for the male part 11 of the first connector 1.
Aussi bien la paroi de protection 3 que la cloison de protection 4 sont prévus pour durer durant toute la période d’utilisation des deux raccords, sans être remplacés, facilitant l’utilisation de ces deux raccords.Both the protective wall 3 and the protective partition 4 are designed to last for the entire period of use of the two connectors, without being replaced, facilitating the use of these two connectors.
Tel que connu, un clip de fixation 5 permet de maintenir l’ensemble de raccords après son assemblage rapide par un unique mouvement de translation, le démontage de cet ensemble de raccords, imposant le retrait préalable du clip de fixation 5.As known, a fixing clip 5 makes it possible to maintain the set of fittings after its rapid assembly by a single translational movement, the dismantling of this set of fittings, requiring the prior removal of the fixing clip 5.
Bien entendu, un tel clip de fixation 5 ne doit pas perturber le fonctionnement de la paroi de protection 3 et de la cloison de protection 4 lors de l’assemblage de l’ensemble de raccords.Of course, such a fixing clip 5 must not disturb the operation of the protective wall 3 and of the protective partition 4 during the assembly of the set of fittings.
