Description

La présente invention concerne les connecteurs électriques verrouillables par poussée et déverrouillables par traction sur une bague de verrouillage de l'un des éléments du connecteur. On connaít de nombreux connecteurs électriques de ce type, qui ont l'avantage de pouvoir être accouplés et désaccouplés par un simple mouvement linéaire.The present invention relates to electrical connectors lockable by push and unlockable by traction on a locking ring of one of the elements of the connector. We know many electrical connectors of this type, which have the advantage of being able to be coupled and uncoupled by a simple linear movement.

En particulier, le document FR-A-2 690 569 décrit un tel connecteur électrique comprenant :

  • une embase ayant un corps présentant une jupe tubulaire avant dans laquelle est retenue au moins une bille déplaçable radialement entre une position externe où elle est en saillie par rapport à la paroi externe de la jupe et affleure l'intérieur et une position interne où elle est en saillie par rapport à la paroi interne de la jupe et affleure l'extérieur, et
  • une fiche ayant :
    • un corps insérable dans la jupe et ayant au moins une empreinte de réception de la bille, le corps de fiche interdisant la venue de la bille en position interne, sauf lorsqu'il est complètement inséré dans la jupe et présente alors son empreinte en face de la bille,
    • une bague de verrouillage déplaçable axialement sur le corps vers une position avant de butée, vers laquelle elle est repoussée par des moyens élastiques et à partir de cette position avant de butée,
    • une bague chasse-bille interposée radialement entre le corps de fiche et la bague de verrouillage, présentant un clavetage coulissant avec la bague de verrouillage, déplaçable axialement par rapport à la bague de verrouillage vers une position avant vers laquelle elle est repoussée par des moyens élastiques et à partir de cette position avant contre l'action desdits moyens élastiques, ladite bague chasse-bille ayant un diamètre interne tel qu'elle maintient la bille en position interne lorsqu'elle la recouvre.
In particular, document FR-A-2 690 569 describes such an electrical connector comprising:
  • a base having a body having a front tubular skirt in which is retained at least one ball displaceable radially between an external position where it projects from the external wall of the skirt and is flush with the interior and an internal position where it is projecting from the internal wall of the skirt and flush with the outside, and
  • a file having:
    • a body insertable into the skirt and having at least one impression for receiving the ball, the plug body preventing the coming of the ball in the internal position, except when it is completely inserted in the skirt and then presents its impression opposite the marble,
    • a locking ring movable axially on the body towards a front stop position, towards which it is pushed back by elastic means and from this front stop position,
    • a ball ring interposed radially between the plug body and the locking ring, having a sliding keyway with the locking ring, movable axially relative to the locking ring towards a front position towards which it is pushed back by elastic means and from this front position against the action of said elastic means, said ball-removing ring having an internal diameter such that it keeps the ball in internal position when it covers it.

Les termes "embase" et "fiche" sont utilisés pour des raisons de commodité. Ils n'impliquent en rien que l'embase soit fixée de façon permanente, bien qu'en général elle appartienne à un appareillage fixe alors que la fiche est raccordée à un câble.The terms "base" and "plug" are used for reasons of convenience. They only involve the base is permanently fixed, although in general it belongs to a fixed device while the plug is connected to a cable.

L'un des modes de réalisation décrits dans le document déjà cité permet d'accoupler le connecteur en tenant la fiche soit par le corps, soit par la bague de verrouillage, ce qui facilite l'insertion. Mais il utilise pour cela deux encliquetages qui viennent alternativement en prise lors des opérations d'insertion. A un instant donné, lors de l'insertion, aucun des deux encliquetages n'est engagé, ce qui crée une incertitude. Dans la plupart des cas elle est sans inconvénient mais on souhaite l'exclure pour les applications qui exigent une grande sécurité.One of the embodiments described in the document already mentioned allows the connector to be coupled by holding the plug either by the body or by the locking ring, which facilitates insertion. But he uses two snaps which engage alternately during insertion operations. At a given time, during insertion, neither of the two snaps is engaged, which creates uncertainty. In most cases it is without disadvantage but we wish to exclude it for applications which require great security.

La présente invention vise notamment à fournir un connecteur électrique du type décrit ci-dessus, conservant tous les avantages que l'on peut en obtenir mais sans présenter ses inconvénients.The present invention aims in particular to provide a electrical connector of the type described above, retaining all the benefits you can get but without present its disadvantages.

Dans ce but, l'invention propose notamment un connecteur électrique suivant la revendication 1.To this end, the invention notably proposes a connector electric device according to claim 1.

Pour réduire le diamètre du connecteur, les moyens élastiques peuvent être constitués par des ressorts à pincettes, ayant des branches courbes de façon à pouvoir placer ces ressorts dans un espace annulaire étroit à l'intérieur de la bague de verrouillage.To reduce the diameter of the connector, the means elastic can be constituted by springs with tweezers, having curved branches so that they can place these springs in a narrow annular space at inside the locking ring.

Pour en faciliter la réalisation, la bague chasse-bille peut être constituée en plusieurs parties assemblées, ainsi que le manchon.To make it easier, the ball ring can be made up of several assembled parts, as well than the sleeve.

Les caractéristiques ci-dessus ainsi que d'autres apparaítront mieux à la lecture de la description qui suit d'un mode particulier de réalisation, donné à titre d'exemple non limitatif. La description se réfère aux dessins qui l'accompagnent, dans lesquels :

  • la figure 1 montre un connecteur suivant un mode particulier de réalisation de l'invention, à l'état découplé, en coupe suivant un plan passant par l'axe ;
  • la figure 2 est une vue de détail à grande échelle montrant les éléments du connecteur dans la position qu'ils occupent lorsque la bague chasse-bille vient en contact avec la bille ;
  • la figure 3 est une vue de détail montrant la disposition prise par les différents éléments lorsque le corps de la fiche a avancé par rapport à la position montrée en figure 2 ;
  • la figure 4, similaire à la figure 1, montre le connecteur en position verrouillée ;
  • les figures 5 et 6 montrent un ressort à pincettes. Le connecteur représenté en figure 1 est constitué d'une embase A et d'une fiche B.
The above characteristics as well as others will appear better on reading the following description of a particular embodiment, given by way of non-limiting example. The description refers to the accompanying drawings, in which:
  • Figure 1 shows a connector according to a particular embodiment of the invention, in the decoupled state, in section along a plane passing through the axis;
  • Figure 2 is a detail view on a large scale showing the connector elements in the position they occupy when the ball ring comes into contact with the ball;
  • Figure 3 is a detail view showing the arrangement made by the different elements when the body of the plug has advanced relative to the position shown in Figure 2;
  • Figure 4, similar to Figure 1, shows the connector in the locked position;
  • Figures 5 and 6 show a pincer spring. The connector shown in Figure 1 consists of a socket A and a plug B.

L'embase A comporte un corps 1 dont la partie avant est constituée par une jupe annulaire 2 ayant une forme de révolution. Dans le corps est immobilisé un isolant 40 percé de passages 42 de réception de bornes de contact 44. L'arrière du corps contient un passe-fils 46 dans lequel sont ménagés des trous de passage pour des conducteurs reliés aux bornes 44.The base A comprises a body 1, the front part of which is constituted by an annular skirt 2 having a shape of revolution. In the body is immobilized an insulator 40 pierced of passages 42 for receiving contact terminals 44. The back of the body contains a grommet 46 in which through holes are provided for conductors connected to terminals 44.

Dans la jupe 2 sont ménagés des trous radiaux dans lesquels sont emprisonnées des billes 3, par exemple au nombre de trois régulièrement réparties dans le sens circonférentiel. Un sertissage, non représenté, n'autorise les billes qu'à se déplacer entre une position interne dans le sens radial, représentée en figure 1, et une position externe dans le sens radial, représentée en figures 3 et 4. In the skirt 2 are provided radial holes in which are trapped balls 3, for example at number of three evenly distributed in the direction circumferential. A crimping, not shown, does not authorize the balls only to move between an internal position in the radial direction, shown in Figure 1, and a position external in the radial direction, represented in FIGS. 3 and 4.

La fiche B comporte également un corps 4 qui contient également un isolant 48 retenu en place par une plaquette 50 et un passe-fils 52, portant des bornes mâles. La partie avant de ce corps est également tubulaire et de révolution. Elle est prévue pour s'engager avec un faible jeu dans la jupe 2.Sheet B also includes a body 4 which contains also an insulator 48 retained in place by a plate 50 and a grommet 52, carrying male terminals. The part front of this body is also tubular and of revolution. It is intended to engage with a small clearance in the skirt 2.

Dans la paroi externe du corps de fiche 4 est ménagée une gorge annulaire 5 à un emplacement tel qu'elle soit en face des billes 3 lorsque le connecteur est dans une position de plein engagement (figure 4).In the outer wall of the plug body 4 is provided an annular groove 5 in a location such that it is in face of the balls 3 when the connector is in a full engagement position (Figure 4).

Le corps de fiche 5 présente une collerette 10 d'appui sur un épaulement interne d'une bague de verrouillage 6. La collerette 10 limite ainsi le déplacement de la bague de verrouillage 6 vers l'avant par rapport au corps de fiche 4. Le déplacement vers l'arrière de la bague est limité par des moyens qui seront décrits plus loin.The plug body 5 has a support flange 10 on an internal shoulder of a locking ring 6. The flange 10 thus limits the movement of the ring locking 6 forwards with respect to the plug body 4. The rearward movement of the ring is limited by means which will be described later.

Dans l'intervalle radial entre le corps de fiche 4 et la bague de verrouillage 6 est disposée une bague chasse-bille 7. La bague chasse-bille 7 est immobilisée en rotation par rapport à la bague de verrouillage 6 par des moyens de clavetage coulissant, comportant par exemple des rainures longitudinales 17, ménagées sur la face interne de la bague de verrouillage, et des clavettes 18 et 20 appartenant à la bague chasse-bille, qui s'engagent dans les rainures. Le déplacement vers l'avant de la bague chasse-bille 7, par rapport à la bague de verrouillage 6, est limité par son appui contre une butée 22 qui peut être constituée par un circlip emprisonné dans une gorge circonférentielle de la bague de verrouillage.In the radial interval between the plug body 4 and the locking ring 6 is arranged a ball ring 7. The ball ring 7 is immobilized in rotation relative to the locking ring 6 by means of sliding keyway, for example having grooves longitudinal 17, formed on the inner face of the ring lock, and keys 18 and 20 belonging to the ball punch ring, which engage in the grooves. The forward movement of the ball ring 7, by compared to the locking ring 6, is limited by its support against a stop 22 which can be constituted by a circlip trapped in a circumferential groove of the locking ring.

La bague chasse-bille est complétée par une douille de guidage 19 montée à frottement doux sur elle et également munie de clavettes 20. Des moyens élastiques tendent à repousser la bague chasse-bille 7 vers la butée 22 et la bague de verrouillage 6 vers sa postion d'appui contre la collerette 10.The ball ring is completed by a socket guide 19 mounted with gentle friction on it and also provided with keys 20. Elastic means tend to push the ball ring 7 towards the stop 22 and the locking ring 6 towards its support position against the flange 10.

Les moyens élastiques comportent un manchon qui a également pour rôle d'immobiliser la bague de verrouillage en rotation aussi longtemps que le connecteur n'est pas verrouillé et de la libérer ensuite pour fournir une indication tactile du verrouillage.The elastic means comprise a sleeve which has also for the role of immobilizing the locking ring rotating as long as the connector is not locked and then release it to provide a tactile indication of locking.

Le manchon 24 est monté sur le corps 4 et présente avec lui un clavetage coulissant, constitué par exemple par une ou des rainures internes du manchon et une ou des clavettes 26 montées sur le corps. Un premier ressort 28, représenté sur la figure 1 par une flèche double, est interposé entre la collerette 10 et le manchon. Il tend à repousser le manchon vers l'avant. Un second ressort, schématisé par une flèche double 30, tend à écarter l'un de l'autre le manchon 24 et la bague chasse-bille 7. Dans le cas illustré sur les figures, la bague chasse-bille 7 est en plusieurs pièces. Elle comprend une bague proprement dite 7, à laquelle est fixée la clavette 18, et une douille 34 montée à frottement doux sur la bague proprement dite 7, munie de la clavette ou des clavettes 20.The sleeve 24 is mounted on the body 4 and has with a sliding keyway, constituted for example by a or internal grooves of the sleeve and one or more keys 26 mounted on the body. A first spring 28, shown in Figure 1 by a double arrow, is interposed between the collar 10 and the sleeve. It tends to repel the sleeve forward. A second spring, shown schematically by a double arrow 30, tends to separate the sleeve from each other 24 and the ball-ring 7. In the case illustrated on the Figures, the ball ring 7 is in several parts. It comprises a ring proper 7, to which is fixed the key 18, and a sleeve 34 mounted frictionally soft on the ring proper 7, fitted with the key or keys 20.

Les ressorts 28 et 30 sont avantageusement des ressorts à pincettes de forme courbe, pouvant par exemple avoir l'aspect montré en figures 5 et 6. La courbure des branches (figure 5) correspond sensiblement au rayon moyen de l'espace annulaire dans lequel il se loge. A l'état de repos, les ressorts peuvent avoir une forme du genre montré en traits pleins sur la figure 6. Lorsqu'ils sont soumis à une force, ils prennent une forme du genre montré en tirets sur cette figure 6. Etant donné qu'ils sont montés entre des éléments solidaires en rotation, ils peuvent comporter des becs d'ancrage dans les éléments qu'ils séparent.The springs 28 and 30 are advantageously springs with tweezers of curved shape, which can for example have the appearance shown in Figures 5 and 6. The curvature of the branches (Figure 5) corresponds approximately to the average radius of the annular space in which it is housed. In the state of rest, the springs can have a shape of the kind shown in solid lines in Figure 6. When subjected to a force they take a form of the kind shown in dashes in this figure 6. Since they are mounted between integral in rotation, they may include anchoring spouts in the elements they separate.

Lorsque le manchon 24 et la bague chasse-bille proprement dite 7 sont en appui mutuel (figures 1, 2 et 3), ils présentent un encliquetage qui leur interdit de tourner l'un par rapport à l'autre. Dans le cas illustré, cet encliquetage est constitué par deux jeux de dents ou de saillies, l'un ménagé sur la tranche arrière de la bague chasse-bille 7, l'autre au fond d'une cavité annulaire ménagée dans le manchon et destinée à recevoir l'extrémité arrière de la bague chasse-bille. Le ressort 30 est interposé entre la bague chasse-bille 7 et la douille 19 qui le maintient au contact avec le manchon 24.When the sleeve 24 and the ball ring properly said 7 are in mutual support (Figures 1, 2 and 3), they have a snap that prevents them from turning one compared to each other. In the illustrated case, this snap consists of two sets of teeth or projections, one on the rear edge of the ball ring 7, the other at the bottom of an annular cavity formed in the sleeve and intended to receive the rear end of the ball punch ring. The spring 30 is interposed between the ball-bushing ring 7 and socket 19 which holds it in place contact with sleeve 24.

La bague chasse-bille peut être en deux pièces, l'une portant les clavettes 18 et s'encliquetant sur le manchon, l'autre réduite à un anneau 34 d'appui sur les billes 3.The ball ring can be in two pieces, one carrying the keys 18 and snapping onto the sleeve, the other reduced to a ring 34 for supporting the balls 3.

Les différents éléments qui viennent d'être décrits sont dimensionnés de façon que le fonctionnement soit le suivant.The various elements which have just been described are dimensioned so that the operation is as follows.

Pour accoupler la fiche et l'embase à partir de la position où elles sont montrées en figure 1, il suffit de pousser la fiche B soit par le corps de fiche 4, soit par la bague 6 qui s'appuie alors sur la collerette 10.To couple the plug and socket from the position where they are shown in figure 1, just push plug B either through plug body 4 or through ring 6 which then rests on the collar 10.

La disposition relative des composants de la fiche reste la même jusqu'à ce que la bague chasse-bille vienne dans la position d'appui contre les billes 3 montrée en figure 2. La bague de verrouillage 6 est toujours immobilisée en rotation, étant donné son clavetage coulissant avec la bague chasse-bille 7, elle-même encliquetée sur le manchon 24, lui-même claveté sur le corps. Des moyens de détrompage, non représentés, sont généralement prévus sur le corps de fiche et le corps d'embase pour n'autoriser l'introduction de la fiche que dans l'orientation convenable.The relative arrangement of the components of the plug remains the same until the ball ring comes into the support position against the balls 3 shown in Figure 2. The locking ring 6 is always immobilized in rotation, given its sliding keying with the ring ball punch 7, itself snapped onto the sleeve 24, itself keyed to the body. Means of coding, no shown, are generally provided on the plug body and the base body to not allow the introduction of the plug only in proper orientation.

Lorsqu'on continue à pousser vers l'avant la bague de verrouillage 6, qui entraíne le corps de fiche 4, la bague chasse-bille 7 recule dans le sens axial, puisque les billes ne peuvent pas s'enfoncer radialement (figure 3). La bague de verrouillage 6 reste immobilisée en rotation.When we continue to push forward the ring lock 6, which drives the plug body 4, the ring ball punch 7 moves back in the axial direction, since the balls cannot sink radially (Figure 3). The ring locking device 6 remains immobilized in rotation.

Il en est de même si on exerce l'effort d'insertion sur le corps de fiche au lieu de l'exercer sur la bague de verrouillage, si ce n'est que la bague de verrouillage peut alors reculer en même temps que la bague chasse-bille.The same is true if the insertion effort is exerted on the plug body instead of exerting it on the locking ring, except that the locking ring can then back off at the same time as the ball-bushing ring.

Lorsque le corps de fiche 4 a suffisamment avancé pour que les billes soient en face des empreintes 5, les billes s'effacent vers l'intérieur sous la poussée de la bague chasse-bille 7, sur laquelle s'exerce la pression du ressort 28, transmise par le manchon 24. Le manchon est dimensionné pour que son avance soit limitée par sa venue en butée contre la butée 22 solidaire de la bague de verrouillage 6, elle même bloquée par la collerette 10 (figure 4). Le ressort 30, plus faible que le ressort 28, prend alors le relais et projette en avant la bague chasse-bille 7 qui se désolidarise en rotation du manchon. La bague chasse-bille 7 est alors de nouveau en appui contre la butée 22. Les billes ne peuvent pas s'échapper, même en cas de traction exercée sur le corps de fiche. La bague de verrouillage est libre en rotation et fournit une confirmation de l'état verrouillé.When the plug body 4 has advanced enough to the balls are opposite the imprints 5, the balls fade inward under the push of the ring ball punch 7, on which the spring pressure is exerted 28, transmitted by the sleeve 24. The sleeve is dimensioned so that its advance is limited by its coming into abutment against the stop 22 integral with the locking ring 6, itself blocked by the collar 10 (Figure 4). The spring 30, weaker than spring 28, then takes the relay and projects forward the ball ring 7 which is disengages in rotation from the sleeve. The ball ring 7 is then again in abutment against the stop 22. The balls cannot escape, even when pulled exerted on the plug body. The locking ring is free to rotate and provides status confirmation Locked.

Le déverrouillage s'effectue en tirant la bague de verrouillage 6 vers l'arrière. La bague de verrouillage entraíne la bague chasse-bille qui libère les billes. La bague de verrouillage ne peut reculer par rapport au corps que jusqu'à ce qu'elle amène en butée le manchon 24 contre la collerette 10. Une fois la fiche dégagée, il suffit de lâcher la bague de verrouillage pour que les éléments de la fiche revienne dans la position montrée en figure 1.Unlocking is carried out by pulling the ring locking 6 towards the rear. The locking ring drives the ball ring which releases the balls. The locking ring cannot move back from the body until it abuts the sleeve 24 against the collar 10. Once the plug is released, it suffices to release the locking ring so that the elements of the plug returns to the position shown in Figure 1.

La bague de verrouillage est alors de nouveau immobilisée en rotation par rapport au corps.The locking ring is then immobilized again rotating relative to the body.

La disposition qui vient d'être décrite permet de remplir les mêmes fonctions que celles de connecteurs antérieurs plus complexes et plus encombrants. La projection de la bague de verrouillage vers l'avant par un ressort garantit un verrouillage franc. A aucun moment il n'y a une incertitude quant à l'encliquetage de la bague de verrouillage.The arrangement which has just been described makes it possible to perform the same functions as those of connectors more complex and bulky forelegs.
