Description Raccord étanche entre une gaine annelée et un emboutDescription Watertight connection between a corrugated sleeve and a nozzle
Domaine technique [0001] L'invention se rapporte à un raccord comprenant une coque s'ouvrant pour dégager un logement. Technical Field [0001] The invention relates to a coupling comprising a hull opening to clear a housing.
Etat de la technique [0002] Un raccord de ce type est connu du document PCT/WO 0120216 A. Ce raccord est utilisé pour raccorder une gaine annelée à un embout destiné à recevoir un tube pour le transport, par exemple, d'un liquide de nettoyage dans un véhicule automobile. La coque s'ouvre pour permettre la mise en place de la gaine annelée dans le logement et pour la retenir par rapport à la coque par l'intermédiaire de moyens de retenue s'insérant, lors de la fermeture de la coque, dans les annelures de la gaine annelée. State of the art [0002] A connector of this type is known from document PCT / WO 0120216 A. This connector is used to connect a corrugated sheath to a nozzle intended to receive a tube for transporting, for example, a liquid cleaning in a motor vehicle. The shell opens to allow the establishment of the corrugated sheath in the housing and to retain it relative to the shell by means of retaining means inserting, when closing the shell, in the corrugations the corrugated sheath.
3] La coque comprend d'autres moyens de retenue venant en prise avec des moyens de retenue formés sur l'embout pour retenir ce dernier par rapport à la coque lorsqu'elle est fermée. Toutefois, l'étanchéité du raccord est assurée par une section de l'embout emmanchée en force dans une section de la gaine.3] The shell comprises other retaining means engaging with retaining means formed on the tip to retain the latter relative to the shell when closed. However, the seal of the connection is provided by a section of the tip forcefully fitted in a section of the sheath.
Divulgation de l'invention [0004] Le but de l'invention est d'augmenter l'étanchéité d'un raccord de ce type tout en permettant une simplification du raccordement entre une gaine annelée et un embout. 2/8 Disclosure of the invention [0004] The object of the invention is to increase the sealing of a connection of this type while allowing a simplification of the connection between a corrugated sheath and a tip. 2/8
5] A cet effet, l'invention a pour objet un raccord comprenant une coque s'ouvrant pour dégager un logement, caractérisé en ce qu'il comprend un joint creux disposé dans le logement pour être retenu par la coque lorsqu'elle est fermée.5] For this purpose, the invention relates to a coupling comprising a shell opening to clear a housing, characterized in that it comprises a hollow seal disposed in the housing to be retained by the shell when closed .
6] Le joint creux permet de raccorder de façon étanche, une gaine annelée à un embout sans nécessiter d'emmancher l'un dans l'autre.6] The hollow seal makes it possible to connect tightly, a corrugated sheath to a tip without having to fit one into the other.
7] Dans un premier mode d'exécution de l'invention, le joint creux est pourvu de moyens de retenue venant en prise avec des moyens de retenue portés par la coque pour retenir le joint creux par rapport à la coque lorsqu'elle est fermée. En particulier, les moyens de retenue ne sont pas en prise réciproque lorsque la coque est ouverte pour permettre de retirer le joint creux et de le monter autour d'une extrémité de la gaine annelée avant de le disposer dans le logement de la coque avec la partie d'extrémité de la gaine annelée.7] In a first embodiment of the invention, the hollow seal is provided with retaining means engaging with retaining means carried by the shell to retain the hollow seal relative to the shell when closed . In particular, the retaining means are not in mutual engagement when the shell is open to allow the hollow seal to be removed and mounted around one end of the corrugated sheath before disposing it in the housing of the shell with the end portion of the corrugated sheath.
8] Selon un deuxième mode d'exécution de l'invention, le joint creux s'ouvre en deux parties fixées à la coque pour se fermer de façon étanche par compression des deux parties l'une contre l'autre lors de la fermeture de la coque. De préférence, les deux parties du joint creux présentent chacune un plan de fermeture plat ou pourvu de reliefs correspondants.8] According to a second embodiment of the invention, the hollow seal opens in two parts attached to the shell to close tightly by compression of the two parts against each other during the closing of shell. Preferably, the two parts of the hollow joint each have a flat closure plane or provided with corresponding reliefs.
9] Avantageusement, un espace est ménagé entre le joint creux et la coque pour accuser une déformation du joint creux lorsque la coque est fermée. On prévoit également que le joint creux possède un profil intérieur 3/8 s'inscrivant dans un tore pour faciliter l'insertion d'une extrémité d'un embout dans le joint creux disposé dans la coque.9] Advantageously, a space is provided between the hollow seal and the shell to show a deformation of the hollow seal when the shell is closed. It is also expected that the hollow seal has a 3/8 inside profile forming a torus to facilitate insertion of an end of a tip into the hollow seal disposed in the shell.

0] D'autres avantages de l'invention sont décrits ci-après à l'aide de deux modes d'exécution illustrés par les figures 1 à 3.0] Other advantages of the invention are described below using two embodiments illustrated in Figures 1 to 3.
1] La figure 1 montre en coupe un raccord entre une gaine annelée et un embout selon l'invention.1] shows in section a connection between a corrugated sheath and a nozzle according to the invention.
2] Les figures 2 et 3 montrent en perspective un raccord selon un premier mode d'exécution de l'invention.2] Figures 2 and 3 show in perspective a connection according to a first embodiment of the invention.
3] La figure 4 montre en perspective un raccord selon un deuxième mode d'exécution de l'invention.3] Figure 4 shows in perspective a connection according to a second embodiment of the invention.
Mode(s) de réalisation de l'invention [0014] Par référence aux figures 1 à 4, un raccord utilisé pour raccorder une gaine annelée 2 à un embout 1 comprend une coque 4 s'ouvrant pour dégager un logement 5. De façon connue, la coque 4 s'ouvre pour permettre la mise en place de la gaine annelée 2 dans le logement 5 et pour la retenir par rapport à la coque 4 par l'intermédiaire de moyens de retenue 4a s'insérant, lors de la fermeture de la coque, dans des annelures de la gaine annelée. Embodiment (s) of the invention [0014] With reference to FIGS. 1 to 4, a coupling used to connect a corrugated sheath 2 to a nozzle 1 comprises a shell 4 opening to release a housing 5. In a known manner , the shell 4 opens to allow the establishment of the corrugated sheath 2 in the housing 5 and to retain it relative to the shell 4 by means of retaining means 4a inserted, when closing the hull, in corrugations of the corrugated sheath.
5] Selon l'invention, le raccord comprend un joint creux 3 disposé dans le logement 5 pour être retenu par la coque 4 lorsqu'elle est fermée. 4/85] According to the invention, the connector comprises a hollow seal 3 disposed in the housing 5 to be retained by the shell 4 when closed. 4/8
6] Dans les deux modes d'exécution illustrés par les figures 1 à 4, le joint creux 3 comprend des rainures de retenue 3d pour venir en prise avec des nervures de retenue 4b de la coque 4.6] In the two embodiments illustrated in FIGS. 1 to 4, the hollow seal 3 comprises retention grooves 3d for engaging with retaining ribs 4b of the shell 4.
7] Selon le premier mode d'exécution de l'invention illustré par les figures 2 et 3, le joint creux 3 est d'une seule pièce et prend appui contre la coque 4 en étant comprimé lorsque la coque est fermée. Les moyens de retenue permettent ainsi au joint creux 3 d'être retiré du logement 5 lorsque la coque 4 est ouverte. Le joint creux 3 peut donc être monté au préalable autour d'une extrémité de la gaine annelée 2. Cet agencement favorise l'étanchéité du raccord dans la mesure où le diamètre extérieur des annelures de la gaine annelée est en général mieux maîtrisé que leur diamètre intérieur. En effet, le diamètre extérieur est directement imposé par l'outillage d'extrusion ayant servi à fabriquer une gaine annelée selon un tel procédé alors que le diamètre intérieur dépend de l'épaisseur locale de la gaine annelée elle-même.7] According to the first embodiment of the invention illustrated in Figures 2 and 3, the hollow seal 3 is in one piece and bears against the shell 4 by being compressed when the shell is closed. The retaining means thus allow the hollow seal 3 to be removed from the housing 5 when the shell 4 is open. The hollow seal 3 can therefore be mounted beforehand around one end of the corrugated sheath 2. This arrangement promotes the sealing of the coupling insofar as the outside diameter of the corrugations of the corrugated sheath is generally better controlled than their diameter. inside. Indeed, the outer diameter is directly imposed by the extrusion tool used to make a corrugated sheath according to such a method while the inner diameter depends on the local thickness of the annular sheath itself.
8] Dans le deuxième mode d'exécution illustré par la figure 4, le joint creux 3 s'ouvre en deux parties 31,32 fixées à la coque 4 pour se fermer de façon étanche par compression des deux parties l'une contre l'autre lors de la fermeture de la coque 4. Les deux parties 31,32 du joint creux 3 présentent chacune un plan de fermeture P1,P2 pourvu de reliefs correspondants 41,42. 5/88] In the second embodiment illustrated in FIG. 4, the hollow seal 3 opens in two parts 31, 32 fixed to the shell 4 to close tightly by compression of the two parts against each other. other when closing the shell 4. The two portions 31,32 of the hollow seal 3 each have a closure plane P1, P2 provided with corresponding reliefs 41,42. 5/8
9] Figure 1, un espace 11 est prévu entre une extrémité du joint creux 3 et un extrémité de la coque 4 pour accuser une déformation du joint creux 3 lorsque la coque 4 est fermée.9] Figure 1, a space 11 is provided between one end of the hollow seal 3 and one end of the shell 4 to deform the hollow seal 3 when the shell 4 is closed.
0] Dans l'un ou l'autre des modes d'exécution de l'invention, la coque 4 comprend un anneau 4c limitant en section le logement 5 de façon à restreindre un possible jeu entre la coque 4 et l'embout 1 inséré dans le joint creux 3. On diminue ainsi un risque de fuite qui serait dû à une déviation de l'embout par rapport à la coque.0] In one or other of the embodiments of the invention, the shell 4 comprises a ring 4c limiting in section the housing 5 so as to restrict a possible clearance between the shell 4 and the tip 1 inserted in the hollow joint 3. This reduces a risk of leakage that would be due to a deviation of the tip relative to the hull.
1] Le joint creux est de préférence un joint de forme en élastomère et possède un profil intérieur 3b s'inscrivant dans un tore pour améliorer le rapport entre l'effort d'enfoncement de l'embout 1 dans le joint creux 3 et. l'effort d'arrachement de cet embout, en diminuant l'effort d'enfoncement, par exemple par rapport à un contact résultant d'un profil intérieur inscrit dans un cône, à même étanchéité. Un épaulement intérieur 3c permet avantageusement d'augmenter l'effort d'arrachement de l'embout 1.1] The hollow seal is preferably an elastomer shaped seal and has an internal profile 3b forming part of a torus to improve the ratio between the driving force of the tip 1 in the hollow joint 3 and. the pulling force of this nozzle, by decreasing the driving force, for example with respect to a resulting contact with an internal profile inscribed in a cone, with same tightness. An inner shoulder 3c advantageously makes it possible to increase the tearing force of the endpiece 1.
2] La coque 4 est de préférence fabriquée en matière plastique, en une pièce comportant une charnière 8 pour articuler deux demi coques 43, 44 l'une par rapport à l'autre, ou en deux demi coques amovibles 45,46 pour ouvrir la coque 4. Des moyens de verrouillage 10,12 permettent de maintenir les deux demi coques l'une contre l'autre pour fermer la coque. Une coque à deux demi-coques articulées par une charnière ou amovibles l'une par rapport à l'autre s'applique aussi bien à un joint d'une seule pièce selon le 6/8 premier mode d'exécution de l'invention qu'à un joint en deux parties fixées chacune à chaque demi-coque.2] The shell 4 is preferably made of plastic, in one piece having a hinge 8 to articulate two half-shells 43, 44 relative to each other, or two removable half-shells 45.46 to open the hull 4. Locking means 10,12 keep the two half-hulls against each other to close the hull. A hull with two half-hulls articulated by a hinge or movable relative to each other is equally applicable to a one-piece seal according to the first embodiment of the invention to a joint in two parts each attached to each half-shell.
3] Suivant le deuxième mode d'exécution de l'invention, les deux parties 31,32 du joint creux 3 et les deux demi coques 43,44 ou 45,46 sont fabriquées par un procédé de bi-injection. On choisit des matières plastiques à injecter compatibles pour fixer les deux parties du joint aux deux parties de la coque par liaison moléculaire.3] According to the second embodiment of the invention, the two parts 31,32 of the hollow seal 3 and the two half-shells 43,44 or 45,46 are manufactured by a bi-injection method. Compatible plastics materials are chosen to fix the two parts of the joint to both parts of the shell by molecular bonding.
4] Le raccord selon l'invention permet de raccorder entre eux la gaine annelée 2 et l'embout 1 d'une façon manuelle, sans nécessiter un outil particulier. Comme visible sur les figures 1 et 4, le joint creux 3 est pourvu d'une nervure d'indexation 3a destinée à s'insérer dans une annelure de la gaine annelée 2 pour indexer en position les deux pièces et ainsi garantir un bon emmanchement entre le joint creux et la gaine annelée. 7/84] The connection according to the invention makes it possible to connect the corrugated sheath 2 and the end-piece 1 to each other in a manual manner, without requiring a particular tool. As can be seen in FIGS. 1 and 4, the hollow seal 3 is provided with an indexing rib 3a intended to fit into a corrugation of the corrugated sheath 2 in order to index the two parts in position and thus to ensure a good fit between the hollow joint and the corrugated sheath. 7/8
