Abstract
Description
La présente invention concerne un connecteur rapide comportant une partie mâle et une partie femelle qui s1accou- plent par simple introduction de l'une dans l'autre. The present invention relates to a quick connector comprising a male part and a female part which are coupled by simple introduction of one into the other.
Dans des circuits traversés par des fluides sous pression et qui mettent en oeuvre des connecteurs rapides, il est souhaitable, voire exigé, de mettre en oeuvre des moyens de verrouillage positif de la connexion. En effet, une connexion mal réalisée est tout d'abord une source de fuite et est un risque de désaccouplement dont la conséquence la plus bénigne est de mettre en panne la machine comportant ces circuits de fluide sous pression et, si cette machine est une automobile, d'être une source d'accident (absence de pression dans les circuits pneumatiques de freinage, fuite de carburant à l'intérieur du compartiment moteur pouvant conduire à un incendie...). In circuits crossed by pressurized fluids and which use quick connectors, it is desirable, even required, to use positive locking means of the connection. Indeed, a poorly made connection is first of all a source of leakage and is a risk of uncoupling, the most benign consequence of which is to break down the machine comprising these circuits of pressurized fluid and, if this machine is an automobile , to be a source of accident (absence of pressure in the pneumatic braking circuits, fuel leak inside the engine compartment which could lead to a fire ...).
I1 existe de nombreux dispositifs de verrouillage de l'élément mâle dans l'élément femelle d'un connecteur rapide. Ils fonctionnent sensiblement tous sur le même principe et mettent en oeuvre un moyen général identique consistant en un organe de clavetage qui s'interpose entre une surface radiale de l'embout (gorge ou collerette) et une surface radiale de l'élément femelle (gorge ou collerette également). Cet organe de clavetage peut être introduit manuellement ou peut être maintenu dans sa position de verrouillage par un organe élastique de rappel a l'encontre de l'effet duquel il peut être placé dans un état escamoté (soit déplacé soit déformé) lors de l'introduction de l'embout. There are numerous devices for locking the male element in the female element of a quick connector. They operate substantially all on the same principle and use an identical general means consisting of a locking member which is interposed between a radial surface of the end piece (groove or collar) and a radial surface of the female element (groove or also bezel). This keying member can be introduced manually or can be kept in its locking position by an elastic return member against the effect of which it can be placed in a retracted state (either moved or deformed) during the introduction of the nozzle.
La présente invention entend proposer un mode de réalisation particulièrement simple de ce dispositif de verrouillage mis en oeuvre dans un connecteur rapide. The present invention intends to propose a particularly simple embodiment of this locking device implemented in a quick connector.
A cet effet elle a donc pour objet un connecteur rapide comportant une pièce femelle avec un alésage étagé dont une section de grand diamètre peut accueillir une collerette extérieure d'une pièce male du connecteur au-delà dlun verrou dans lequel le verrou est constitué par une bague montée à coulissement radial dans un logement ménagé dans la pièce femelle au niveau de cette section de son alésage entre une première position de repos et de verrouillage où elle est excentrée par rapport à l'axe de cette section de l'alésage et une seconde position escamotée où elle est sensiblement coaxiale avec cette section de cet alésage. En outre, ce connecteur comporte un organe élastique interposé entre la bague et la pièce tendant à rappeler la bague dans sa première position. De préférence, cet organe élastique est constitué par deux lames en une seule pièce avec la bague. To this end it therefore relates to a quick connector comprising a female part with a stepped bore, a large diameter section can accommodate an outer collar of a male part of the connector beyond a bolt in which the bolt is constituted by a ring mounted to slide radially in a housing formed in the female part at this section of its bore between a first rest and locking position where it is eccentric relative to the axis of this section of the bore and a second retracted position where it is substantially coaxial with this section of this bore. In addition, this connector comprises an elastic member interposed between the ring and the part tending to return the ring to its first position. Preferably, this elastic member is constituted by two blades in one piece with the ring.
D'autres caractéristiques et avantages de l'inven- tion ressortiront de la description, donnée ci-après à titre d'exemple, d'un mode de sa réalisation. Other characteristics and advantages of the invention will emerge from the description, given below by way of example, of an embodiment of it.

FIG. 1 is a view in axial section of the female part of a connector according to the invention,
- Figure 2 is a sectional view along the line
II-II of Figure 1,
- Figure 3 is a sectional view identical to that of Figure 1 illustrating the correctly made and locked connection of the female part and the male part of this connector.
Un connecteur selon l'invention comporte une pièce femelle 1 divisée en plusieurs sections. Une première section 2 possède un canal intérieur 3 et des moyens extérieurs 4, dits en dent de sapin, pour être introduite à l'intérieur d'un tube non représenté. La deuxième section 5 de cette pièce 1 comporte un alésage 6 de diamètre déterminé pour accueillir le nez d'un embout 7 formant la pièce male du connecteur. A connector according to the invention comprises a female part 1 divided into several sections. A first section 2 has an internal channel 3 and external means 4, called fir tree tooth, to be introduced inside a tube not shown. The second section 5 of this part 1 has a bore 6 of determined diameter to accommodate the nose of a tip 7 forming the male part of the connector.
La troisième section 8 de cette pièce male comporte un alésage 9 de diamètre plus important que l'alésage 6 pour accueillir deux joints toriques 10 et un insert de blocage de ceux-ci 11. Le diamètre intérieur de l'insert est égal au diamètre de l'alésage 6. Enfin la pièce femelle 1 comporte une troisième section 12 dont le diamètre intérieur 13 est encore plus important que celui des alésages précédents pour pouvoir permettre le passage libre d'une collerette 14 portée par l'embout 7. A son extrémité ouverte sur l'extérieur, la dernière section 12 de la pièce femelle 1 comporte un verrou pour empêcher l'extraction de l'embout 7 lorsqu'il est introduit correctement dans la pièce femelle 1. Ce verrou est constitué par une bague 15 qui peut coulisser radialement dans la pièce femelle 1 dans un logement ouvert, réalisé dans celle-ci et qui comporte deux pattes élastiques extérieures 16 qui tendent à désaxer l'alésage intérieur de la bague 15 par rapport à l'alésage 13. La partie de cet alésage intérieur de la bague 15 située d'un côté des pattes 16 est en forme de surface conique 17 dont le sommet est situé du côté des autres sections de 1'alésage, de sorte qu'au passage de la collerette 14, cette surface forme rampe pour réaligner les axes de l'alésage de la bague 15 et de l'alésage 13 de la pièce 1. La bague 15 peut alors se déplacer l'encontre de l'effet des lames élastiques 16 jusqu'a ce que la collerette 14 soit logée dans l'alésage 13 au-del de cette bague 15. The third section 8 of this male part has a bore 9 of larger diameter than the bore 6 to accommodate two O-rings 10 and a blocking insert for these 11. The inside diameter of the insert is equal to the diameter of the bore 6. Finally the female part 1 has a third section 12 whose internal diameter 13 is even larger than that of the preceding bores in order to allow the free passage of a flange 14 carried by the end piece 7. At its end open to the outside, the last section 12 of the female part 1 includes a lock to prevent the extraction of the end piece 7 when it is correctly inserted into the female part 1. This lock consists of a ring 15 which can slide radially in the female part 1 in an open housing, produced in the latter and which comprises two external elastic tabs 16 which tend to offset the internal bore of the ring 15 relative to to the bore 13. The part of this internal bore of the ring 15 situated on one side of the legs 16 is in the form of a conical surface 17 the apex of which is situated on the side of the other sections of the bore, so that when the flange 14 passes, this surface forms a ramp to realign the axes of the bore of the ring 15 and of the bore 13 of the part 1. The ring 15 can then move against the effect of the blades elastic 16 until the flange 14 is housed in the bore 13 beyond this ring 15.
Les languettes 16 sont alors décomprimées et la bague se retrouve en position libre excentrée par rapport à l'alésage 13 et l'un de ces flancs prend contact avec le flanc arrière de la collerette 14 et constitue une butée s'opposant à l'extraction de l'embout 7.The tongues 16 are then decompressed and the ring is in the free eccentric position relative to the bore 13 and one of these flanks makes contact with the rear flank of the flange 14 and constitutes a stop opposing the extraction tip 7.
Cet état du connecteur est représenté à la figure 3 et illustre une connexion correctement réalisée. Le logement radial de la bague 15 dans la pièce femelle 1 est représenté sur la figure 2. Il est limité latéralement par deux flancs parallèles 18, 19 contre lesquels portent à coulissement des méplats 20 et 21 de la bague 15. Les flancs 18 et 19 comportent une saillie 22 qui constitue une butée au coulissement vers le haut de la bague 15 en interférant avec le trajet d'une saillie 23 portée par les méplats 20 et 21 de la bague 15. Cette figure illustre l'effet des pattes 16 qui maintiennent l'alésage de la bague 15 décalé d'une valeur "e" par rapport à l'axe de l'alésage 13 de la bague en forçant les saillies 22 et 23 qui sont en dent de sapin à être en butée l'une contre l'autre. On indiquera que la matière utilisée pour la pièce 1 et la bague 15 (ou l'un de ces deux éléments) est suffisamment élastique pour permettre l'introduction de la bague dans son logement avec glissement des saillies 22 et 23 l'une sur l'autre. This state of the connector is shown in Figure 3 and illustrates a properly made connection. The radial housing of the ring 15 in the female part 1 is shown in FIG. 2. It is laterally limited by two parallel flanks 18, 19 against which the flats 20 and 21 of the ring 15 slide. The flanks 18 and 19 have a projection 22 which constitutes a stop for the upward sliding of the ring 15 by interfering with the path of a projection 23 carried by the flats 20 and 21 of the ring 15. This figure illustrates the effect of the legs 16 which hold the bore of the ring 15 offset by a value "e" with respect to the axis of the bore 13 of the ring by forcing the protrusions 22 and 23 which are in fir tooth to be in abutment against one the other. It will be indicated that the material used for the part 1 and the ring 15 (or one of these two elements) is sufficiently elastic to allow the introduction of the ring into its housing with sliding of the projections 22 and 23 one on the 'other.
