Abstract

The mechanism consists of two locking rings (10,20) each forming a sleeve (13,23) surrounding a part of the connector. Each ring has a guide groove (12,22) extending in an arc round the sleeve and made in the thickness of the sleeve wall, and a tongue (11,21) which engages with the groove in the opposite ring. A spring inside the coupling pushes the two rings apart so that projections on the ends of the tongues are locked in matching recesses in the grooves.

Description

La présente invention concerne un dispositif de verrouillage hermaphrodite pour un connecteur.The present invention relates to a device for Hermaphroditic locking for a connector.

Ce dispositif de verrouillage peut être mis en oeuvre pour tous types de connecteurs, et en particulier pour des connecteurs électriques et des connecteurs de fibres optiques.This locking device can be put in work for all types of connectors, and in particular for electrical connectors and connectors optical fiber.

Dans un dispositif de verrouillage hermaphrodite, les deux éléments de connecteurs sont par définition identiques et comportent respectivement des moyens complémentaires adaptés à coopérer pour solidariser les deux éléments de connecteurs.In a locking device hermaphrodite, the two connector elements are by identical definitions and respectively contain complementary means adapted to cooperate for secure the two connector elements.

Un tel dispositif de verrouillage est décrit dans la demande de brevet français n°2 588 387. Elle concerne des éléments de connecteurs hermaphrodites pour fibres optiques. Chaque élément de connecteur comporte une rampe de verrouillage adaptée à être logée dans une gorge de l'autre élément de connecteur lorsque ces deux éléments de connecteur sont pivotés dans des sens de rotation opposés.Such a locking device is described in French patent application No. 2,588,387. relates to hermaphroditic connector elements for optical fiber. Each connector element has a locking ramp adapted to be housed in a groove of the other connector element when these two connector elements are rotated in opposite rotation.

Le verrouillage est ainsi assuré par un système à rampes hélicoïdales basé sur le principe de cames linéaires, permettant de rapprocher les deux éléments de connecteurs lors de leur connexion par un mouvement de rotation.Locking is thus ensured by a system with helical ramps based on the cam principle linear, allowing to bring together the two elements of connectors when connected by a movement of rotation.

En outre, pour assurer un positionnement correct des deux éléments de connecteurs, chacun d'eux comporte une aiguille adaptée à pénétrer dans un alésage complémentaire prévu sur l'autre élément de connecteur.In addition, to ensure correct positioning of the two connector elements, each of them has a needle adapted to penetrate a bore additional provided on the other connector element.

Une indexation en rotation des deux éléments de connecteur est ainsi réalisée lors de l'assemblage.An indexing in rotation of the two elements of connector is thus produced during assembly.

En outre, un écrou de verrouillage est prévu dans certaines réalisations.In addition, a locking nut is provided in some realizations.

Ces connecteurs connus sont complexes, composés d'un nombre de pièces relativement important. Leur montage et usinage sont difficiles, ce qui augmente le coût de fabrication de ces connecteurs.These known connectors are complex, composed a relatively large number of parts. Their assembly and machining are difficult, which increases the cost of manufacturing these connectors.

La présente invention a pour but de résoudre ces inconvénients et de proposer un dispositif de verrouillage de conception simplifiée, permettant d'assurer une connexion précise des éléments de connecteurs tout en mettant en oeuvre un minimum de pièces.The object of the present invention is to resolve these disadvantages and to propose a device for simplified design locking, allowing to ensure a precise connection of the elements of connectors while implementing a minimum of rooms.

Le dispositif de verrouillage de deux éléments de connecteurs visé par l'invention comprend deux bagues de verrouillage identiques formant un manchon autour respectivement d'un élément de connecteur.The locking device of two elements of connectors covered by the invention comprises two rings identical locks forming a sleeve around respectively of a connector element.

Suivant l'invention, chaque bague de verrouillage comprend une rainure de guidage et une patte d'accrochage adaptée à venir en prise dans une extrémité de liaison de la rainure de guidage de l'autre bague de verrouillage, des moyens formant ressort étant adaptés à exercer une force d'écartement sur les deux bagues de verrouillage.According to the invention, each ring of lock includes a guide groove and a suitable lug to come into engagement in a connecting end of the other guide groove locking ring, spring means being adapted to exert a spreading force on both locking rings.

Ainsi, la connexion est réalisée de manière très simple, par une patte d'accrochage en prise dans une extrémité de rainure.So the connection is made very simple, by a hooking lug engaged in a groove end.

Cette liaison est renforcée grâce aux moyens formant ressort qui, tout en exerçant une force tendant à écarter les bagues de verrouillage, permettent de manière avantageuse, de renforcer l'accrochage de la patte dans la rainure.This link is reinforced thanks to the means forming a spring which, while exerting a tending force to move aside the locking rings, allow advantageously, to strengthen the attachment of the tab in the groove.

En outre, la fixation de la patte d'accrochage dans l'extrémité de la rainure, au bout de sa course dans la rainure de guidage, permet d'assurer dans un même temps le positionnement correct et l'indexage en rotation des deux éléments de connecteur lors de leur connexion.In addition, the attachment of the hanging tab in the end of the groove, at the end of its stroke in the guide groove, ensures in a at the same time the correct positioning and indexing in rotation of the two connector elements during their connection.

De préférence, la rainure de guidage s'étend suivant un arc de cercle du manchon formé par la bague de verrouillage et est réalisée dans l'épaisseur d'une paroi du manchon, la patte d'accrochage étant formée dans une extrémité de la bague de verrouillage s'étendant au-delà de ladite paroi.Preferably, the guide groove extends along an arc of the sleeve formed by the ring locking and is made in the thickness of a wall of the sleeve, the hooking lug being formed in one end of the locking ring extending beyond said wall.

Ainsi, la paroi de la bague de verrouillage supporte et guide la patte d'accrochage de l'autre bague lorsque celle-ci circule dans la rainure de guidage.So the wall of the locking ring supports and guides the hooking tab of the other ring when it circulates in the guide groove.

En outre, la fixation de la patte d'accrochage dans l'extrémité de la rainure de guidage est réalisée au droit de cette paroi, ce qui permet d'éviter tout glissement de la patte d'accrochage dans une direction radiale du manchon formant la bague de verrouillage.In addition, the attachment of the hanging tab in the end of the guide groove is made to the right of this wall, which avoids any sliding of the latch in one direction radial of the sleeve forming the locking ring.

En référence tout d'abord aux figures 1 à 3, on va décrire ci-dessous une bague de verrouillage du dispositif conforme à l'invention.Referring firstly to Figures 1 to 3, we will describe below a locking ring of the device according to the invention.

Le dispositif de verrouillage permet de réaliser la connexion de deux parties d'un connecteur, tel qu'un connecteur électrique ou de fibres optiques. The locking device allows to realize connecting two parts of a connector, such as a electrical or fiber optic connector.

La liaison, à l'intérieur du connecteur, des câbles est bien connue de l'état de la technique et ne sera pas décrite en détail ci-après.The connection, inside the connector, of the cables is well known in the art and does not will not be described in detail below.

On pourra se reporter notamment à la demande de brevet FR 2 588 387 qui décrit un exemple de connecteur optique.Reference may be made in particular to the request for Patent FR 2 588 387 which describes an example of a connector optical.

La bague de verrouillage 10 forme un manchon 13 autour de l'élément de connecteur et est flottante par rapport à celui-ci.The locking ring 10 forms a sleeve 13 around the connector element and is floating by compared to this one.

La bague de verrouillage est maintenue par exemple au moyen d'un écrou monté sur un pas de vis 1.The locking ring is held in place by example by means of a nut mounted on a thread 1.

La bague de verrouillage comporte une rainure 12 et une extrémité de liaison 14 adaptée à venir en prise avec une patte d'accrochage 21 d'une seconde bague de verrouillage (voir figure 4 par exemple).The locking ring has a groove 12 and a connecting end 14 adapted to come into engagement with a lug 21 for a second ring locking (see Figure 4 for example).

La bague de verrouillage comporte également une patte d'accrochage 11.The locking ring also has a hanging tab 11.

La rainure 12 s'étend suivant un arc de cercle, dans un plan transversal au manchon 13, et est située en regard d'une paroi 15 de la bague de verrouillage.The groove 12 extends along an arc of a circle, in a plane transverse to the sleeve 13, and is located in look of a wall 15 of the locking ring.

La rainure 12 ainsi formée dans l'épaisseur de la paroi 15 du manchon 13 forme ainsi une rampe de guidage sur laquelle peut se déplacer la patte d'accrochage 21 de l'autre bague de verrouillage 20.The groove 12 thus formed in the thickness of the wall 15 of the sleeve 13 thus forms a ramp of guide on which the leg can move hooking 21 of the other locking ring 20.

Cette rainure 12 peut être réalisée par fraisage de la face extérieure de la paroi 15.This groove 12 can be produced by milling of the external face of the wall 15.

La bague de verrouillage 10 comporte en outre une extrémité s'étendant au-delà de la paroi 15 du manchon. Cette extrémité de bague est adaptée à venir s'emboíter sur la paroi 25 de l'autre bague de verrouillage 20 lors de la connexion.The locking ring 10 further comprises one end extending beyond the wall 15 of the muff. This ring end is suitable to come fit onto the wall 25 of the other ring lock 20 when connecting.

Cette extrémité de manchon 13 comporte la patte d'accrochage 11.This sleeve end 13 has the tab hanging 11.

Cette dernière est formée d'une aile, par exemple en forme de "L" s'étendant à partir d'un bras 11a s'étendant suivant l'axe longitudinal Δ du manchon 13.The latter is formed by a wing, by example in the shape of an "L" extending from an arm 11a extending along the longitudinal axis Δ of the sleeve 13.

Dans ce cas, la jambe du "L" est solidaire du bras 11a et s'étend suivant un arc de cercle centré sur l'axe longitudinal Δ du manchon 13 et le pied du "L" s'étend parallèlement à l'axe longitudinal Δ du manchon 13 et forme ainsi un ergot dirigé vers le manchon 13.In this case, the leg of the "L" is secured to the arm 11a and extends in an arc centered on the longitudinal axis Δ of the sleeve 13 and the foot of the "L" extends parallel to the longitudinal axis Δ of the sleeve 13 and thus forms a lug directed towards the sleeve 13.

La rainure 12 comporte, à son extrémité opposée à l'extrémité de liaison 14, une ouverture débouchant dans l'extrémité du manchon 13 et adaptée à l'introduction de la patte d'accrochage 21 solidaire du bras 21a de l'autre bague de verrouillage 20.The groove 12 has, at its opposite end at the connecting end 14, an opening opening in the end of the sleeve 13 and adapted to the introduction of the hooking lug 21 integral with the arm 21a of the other locking ring 20.

Dans cet exemple, la rainure de guidage 12 est délimitée, à son extrémité opposée à l'extrémité de liaison 14, par le bras 11a solidaire de la patte d'accrochage 11.In this example, the guide groove 12 is demarcated, at its end opposite the end of connection 14, by the arm 11a secured to the tab hanging 11.

L'extrémité de liaison 14 de la rainure de guidage 12 comporte un épaulement formant une butée 14a adaptée à venir en prise avec la patte d'accrochage suivant un plan transversal de la rainure de guidage 12.The connecting end 14 of the groove of guide 12 has a shoulder forming a stop 14a adapted to engage with the lug along a transverse plane of the guide groove 12.

Ainsi, cette butée 14a évite toute rotation relative des bagues de verrouillage 10, 20, lorsque celles-ci sont en prise.Thus, this stop 14a avoids any rotation relative to the locking rings 10, 20, when these are in engagement.

L'extrémité de liaison 14 de la rainure de guidage a une forme de "L" identique à celle de la patte d'accrochage 11, la butée 14a étant constituée du pied de la forme en "L".The connecting end 14 of the groove of guide has an "L" shape identical to that of the tab attachment 11, the stop 14a consisting of the foot of the "L" shape.

La butée 14a forme dans la rainure de guidage 12 une section transversale rétrécie, de largeur réduite mais suffisante pour le passage de la patte d'accrochage 21, et au moins égale à la longueur du pied de la forme en "L" de la patte d'accrochage 21.The stop 14a forms in the guide groove 12 a narrowed cross section of reduced width but sufficient for the passage of the hooking lug 21, and at least equal to the length of the foot of the shape in "L" of the hooking lug 21.

Des moyens formant ressort 2, illustrés à la figure 5, sont en outre adaptés à exercer une force d'écartement sur les deux bagues de verrouillage 10, 20. Spring means 2, illustrated in Figure 5, are further adapted to exert a force spacing on the two locking rings 10, 20.

Ces moyens formant ressort 2 peuvent à titre d'exemple être constitués d'un ressort hélicoïdal maintenu en compression entre les deux parois 10a, 20a des extrémités opposées des bagues de verrouillage 10, 20 lorsque la connexion est réalisée.These spring means 2 can by way of example consist of a coil spring maintained in compression between the two walls 10a, 20a opposite ends of the locking rings 10, 20 when the connection is made.

La force de rappel du ressort 2 permet de maintenir les bagues de verrouillage légèrement écartées, de sorte que chaque patte d'accrochage 11, 21, vient en prise dans l'extrémité de liaison 24, 14 de la rainure de guidage 22, 12.The return force of spring 2 allows hold the locking rings slightly spaced apart, so that each hooking tab 11, 21, engages in the connecting end 24, 14 of the guide groove 22, 12.

Chaque patte d'accrochage 11 n'est pas alignée, dans la direction longitudinale Δ du manchon 13, avec l'extrémité de liaison 14 de la rainure 12, mais au contraire sensiblement décalée.Each attachment tab 11 is not aligned, in the longitudinal direction Δ of the sleeve 13, with the connecting end 14 of the groove 12, but at otherwise noticeably offset.

La patte d'accrochage 11 est située en amont de l'extrémité de liaison 14, relativement au sens de rotation F de la bague de verrouillage 10 lors du verrouillage du dispositif.The attachment tab 11 is located upstream of the connecting end 14, relative to the direction of rotation F of the locking ring 10 during locking the device.

La patte d'accrochage 11 peut ainsi pénétrer dans la rainure de guidage 22 de l'autre bague de verrouillage 20, en échappant à l'extrémité de liaison 24 de cette rainure 22.The lug 11 can thus penetrate in the guide groove 22 of the other ring of locking 20, escaping from the connection end 24 of this groove 22.

En outre, les points de liaison des bagues de verrouillage 10, 20, respectivement formés par la patte d'accrochage 11 et l'extrémité de liaison 24, et la patte d'accrochage 21 et l'extrémité de liaison 14 (voir figure 4) sont décalés sur le pourtour périphérique des manchons 13, 23, de sorte que ces points de liaison ne sont pas alignés suivant un axe parallèle à l'axe longitudinal des bagues de verrouillage 10, 20.In addition, the connection points of the rings locking 10, 20, respectively formed by the tab attachment 11 and the connecting end 24, and the hooking lug 21 and the connection end 14 (see Figure 4) are offset around the peripheral periphery of the sleeves 13, 23, so that these connection points do not are not aligned along an axis parallel to the axis longitudinal of the locking rings 10, 20.

Cette disposition permet d'avoir des points de liaison répartis sur le pourtour du dispositif de verrouillage.This arrangement makes it possible to have points of link distributed around the periphery of the locking.

Afin d'améliorer la fixation et de multiplier les points de liaison, la bague de verrouillage 10 comporte deux rainures de guidage 12 et deux pattes d'accrochage 11.In order to improve fixation and multiply the connection points, the locking ring 10 has two guide grooves 12 and two tabs hanging 11.

Les rainures de guidage 12 sont disposées symétriquement par rapport à l'axe longitudinal Δ de la bague de verrouillage 10.The guide grooves 12 are arranged symmetrically with respect to the longitudinal axis Δ of the locking ring 10.

De même, les pattes d'accrochage 11 sont disposées symétriquement par rapport à l'axe longitudinal Δ de la bague de verrouillage 10.Likewise, the attachment tabs 11 are arranged symmetrically with respect to the axis longitudinal Δ of the locking ring 10.

Cette disposition permet d'obtenir des points de fixation répartis symétriquement par rapport à l'axe longitudinal Δ des manchons 13, 23.This arrangement makes it possible to obtain points of fixing distributed symmetrically with respect to the axis longitudinal Δ of sleeves 13, 23.

La seconde bague de verrouillage 20 est en tout point identique à la bague de verrouillage 10 décrite ci-dessus avec laquelle elle est destinée à coopérer lors du verrouillage.The second locking ring 20 is in all identical point to the locking ring 10 described above with which it is intended to cooperate when locking.

Elle comprend un manchon 23 et comporte deux rainures de guidage 22, ayant chacune une extrémité de liaison 24, et une patte d'accrochage 21.It includes a sleeve 23 and has two guide grooves 22, each having one end of link 24, and a lug 21.

Lors de la connexion des deux éléments de connecteurs, comme illustré aux figures 4 à 6, chaque patte d'accrochage 11, 21 est introduite respectivement dans la rainure de guidage 22, 12 de l'autre bague de verrouillage.When connecting the two elements of connectors, as illustrated in figures 4 to 6, each hooking lug 11, 21 is introduced respectively in the guide groove 22, 12 of the other ring locking.

Lors de cette opération, les bras 11a et 21a coulissent parallèlement l'un à l'autre.During this operation, the arms 11a and 21a slide parallel to each other.

Puis les deux bagues de verrouillage 10, 20 sont pivotées dans des sens de rotation F, G opposés, de sorte que chaque patte d'accrochage 11, 21 circule dans la rainure de guidage 22, 12 et passe au-delà de la butée 24a, 14a de l'extrémité de liaison 24, 14.Then the two locking rings 10, 20 are rotated in opposite directions F, G, so that each latch 11, 21 flows in the guide groove 22, 12 and passes beyond the stop 24a, 14a of the connecting end 24, 14.

Lorsque l'utilisateur relâche la pression exercée sur les bagues de verrouillage pour les rapprocher, les moyens formant ressort 2 ont pour effet d'écarter légèrement ces deux bagues de verrouillage, chaque patte d'accrochage 11, 21 venant respectivement en prise avec l'extrémité de liaison 24, 14 et la butée 24a, 14a.When the user releases the pressure exerted on the locking rings for the closer together, the spring means 2 have the effect to slightly separate these two locking rings, each latch 11, 21 coming respectively in engagement with the connecting end 24, 14 and the stop 24a, 14a.

Pour démonter le connecteur, afin de modifier ou réparer le câblage, l'utilisateur doit rapprocher les deux bagues de verrouillage en exerçant une force opposée à la force de rappel développée par les moyens formant ressort 2 et faire pivoter les deux bagues de verrouillage dans des sens opposés aux sens de rotation F et G.To disassemble the connector, to modify or repair the wiring, the user must bring the two locking rings by exerting a force opposite to the restoring force developed by the means forming spring 2 and rotate the two rings of locking in opposite directions to the direction of rotation F and G.

Lorsque chaque patte d'accrochage 11, 21 a échappé aux butées 24a, 14a, les bagues de verrouillage 10, 20 peuvent être désolidarisées.When each fastening tab 11, 21 has escaped the stops 24a, 14a, the locking rings 10, 20 can be separated.

Bien entendu, de nombreuses modifications peuvent être apportées à l'exemple décrit ci-dessus sans sortir du cadre de l'invention.Of course, many modifications can be made to the example described above without depart from the scope of the invention.

Ainsi, chaque bague de verrouillage peut ne comporter qu'une seule rainure de guidage et une patte d'accrochage. Ces dernières peuvent alors être disposées de manière symétrique par rapport à l'axe longitudinal de la bague de verrouillage.Thus, each locking ring may not have only one guide groove and one tab hanging. These can then be arranged symmetrically about the longitudinal axis of the locking ring.
