Description

La présente invention a pour objet un dispositif de fiche pour un cordon standard de liaison électrique ou optique muni à au moins l'une de ses extrémités d'une fiche présentant un corps muni d'un verrou mécanique externe.The subject of the present invention is a plug device for a standard electrical or optical connection cord provided with at least one of its ends of a plug having a body provided with a lock external mechanical.

Actuellement, dans le domaine des installations électriques, les principaux standards de réseaux de terrain industriel ont été créés par des fournisseurs d'automates PROFIBUS par Siemens, FIP par télémécanique, etc.Currently, in the field of electrical installations, the main industrial field network standards have been created by PROFIBUS PLC suppliers by Siemens, FIP by telemechanics, etc.

La tendance actuelle est de s'affranchir des contraintes liées à ces fournisseurs d'automates en utilisant sur le site un réseau de transfert d'informations ouvert, c'est-à-dire non dépendant d'un fournisseur d'automates et qui soit un réel standard mondial.The current trend is to get rid of the constraints linked to these PLC suppliers using a transfer network on the site open information, i.e. not dependent on a supplier which is a real world standard.

Ethernet, qui est un réseau déjà utilisé dans le monde de la bureautique pour relier entre eux les ordinateurs et les périphériques de ceux-ci, remplit ces conditions. La connectique utilisée est dénommée le RJ45. Cette connectique est constituée par un cordon blindé ou non standard aux extrémités duquel sont montées des fiches également standard présentant un corps muni d'un verrou mécanique externe qui peut être escamoté par une action de pression sur l'extrémité du verrou. Ce verrou sert bien sûr pour la fixation mécanique lors de la connexion avec une embase.Ethernet, which is a network already used in the world of office automation to connect computers and peripherals these meet these conditions. The connection used is called the RJ45. This connection consists of a shielded or unshielded cord standard at the ends of which plugs are also mounted standard with a body fitted with an external mechanical lock which can be retracted by a pressure action on the end of the lock. This lock is of course used for mechanical fixing during connection with a base.

Sur la figure 1 annexée, on a représenté l'extrémité d'un cordon standard équipé d'une fiche de type également standard du type RJ45 ou RJ11.In Figure 1 attached, there is shown the end of a cord standard fitted with a plug type also standard of type RJ45 or RJ11.

On y a fait figurer le cordon 10 et sa fiche 12 qui comporte un corps 14 en général surmoulé sur le cordon 10. Sur la face externe du corps 14, est prévu un verrou mécanique 16 qui peut être amené en position non active par une languette 18 formant levier de commande.It included the cord 10 and its plug 12 which has a body 14 generally overmolded on the cord 10. On the external face of the body 14, a mechanical lock 16 is provided which can be brought into non-active position by a tongue 18 forming a control lever.

Si ce type de connectique répond bien aux conditions de la norme Ethernet, il n'est pas du tout adapté à l'environnement de production industriel dans lequel on peut rencontrer des projections de liquide, des chocs, des tractions intempestives sur le cordon, des vibrations, des perturbations électromagnétiques, etc. Les cordons de connexion du type RJ45 ou RJ11 présentent l'avantage supplémentaire qu'ils sont aujourd'hui des cordons standards déjà calibrés avec, à leurs extrémités, deux fiches RJ45 ou RJ11 surmoulées à l'extrémité du cordon. If this type of connection meets the conditions of the Ethernet standard, it is not at all suitable for the environment of industrial production in which projections of liquid, shocks, untimely pulls on the cord, vibrations, electromagnetic disturbances, etc. The cords of RJ45 or RJ11 connection have the additional advantage that they are today standard cords already calibrated with, at their ends, two RJ45 or RJ11 plugs overmolded at the end of the cord.

Une solution pour adapter la connectique RJ45 aux impératifs liés à l'environnement industriel consisterait à désolidariser le cordon standard des fiches et à remplacer celles-ci par des fiches de type classique utilisées dans un environnement industriel.A solution to adapt RJ45 connectors to requirements linked to the industrial environment would consist in separating the cord standard sheets and replace these with type sheets used in an industrial environment.

On comprend cependant qu'une telle solution présente un double inconvénient :

  • d'une part du fait du surmoulage, la suppression des fiches d'origine et le câblage de nouvelles fiches sur le cordon entraínent des frais supplémentaires ; et
  • on perd le bénéfice du fait que le cordon équipé de ses deux fiches surmoulées est déjà calibré risquant ainsi de détériorer les performances de l'ensemble.
    • We understand, however, that such a solution has a double drawback:
  • on the one hand due to overmolding, the deletion of the original plugs and the wiring of new plugs on the cord entail additional costs; and
  • we lose the benefit of the fact that the cord fitted with its two overmolded plugs is already calibrated, thus risking deteriorating the performance of the assembly.

    • Il existe donc un réel besoin de pouvoir transformer un cordon standard électrique muni de fiche du type RJ45 ou analogue en un cordon standard équipé de fiche compatible avec l'environnement industriel, en évitant les inconvénients de la solution rappelée ci-dessus.There is therefore a real need to be able to transform a cord electric standard with RJ45 plug or similar in a cord standard fitted with plug compatible with the industrial environment, in avoiding the drawbacks of the solution recalled above.

    Dans le domaine des transmissions d'informations par des signaux lumineux, il existe des problèmes similaires ou identiques. En effet, on dispose de cordons standard à fibres optiques qui comportent à au moins une de leurs extrémités un corps de fiche muni d'un verrou mécanique. Comme dans le cas des cordons électriques, les cordons optiques de ce type ne sont pas adaptés à une utilisation ou à un environnement de fabrication industriel.In the field of information transmission by light signals, there are similar or identical problems. In Indeed, we have standard fiber optic cords which include at least one of their ends a plug body provided with a lock mechanical. As in the case of electrical cords, the cords optics of this type are not suitable for use or industrial manufacturing environment.

    Il existe donc le même besoin de transformer un cordon standard de connexion optique en cordon équipé d'une fiche compatible avec l'environnement industriel.There is therefore the same need to transform a cord optical cord connection standard fitted with a compatible plug with the industrial environment.

    Pour atteindre ce but, selon l'invention, le dispositif de fiche pour cordon standard de connexion électrique ou optique muni à une extrémité d'une fiche de cordon solidaire du cordon ayant un corps comportant un verrou mécanique externe, est caractérisé en ce que ledit dispositif de fiche comprend :

    • un corps de fiche ;
    • un adaptateur de fiche distinct du corps de fiche comportant des moyens externes de solidarisation dans ledit corps de fiche ;
    • un corps de presse-étoupe comportant un presse-étoupe de forme cylindrique ; et
    • une pièce de liaison ayant une première extrémité de solidarisation avec ledit corps de fiche et une deuxième extrémité munie d'un filet de vissage pour coopérer avec un filet de vissage dudit corps de presse-étoupe ;
       ledit adaptateur de fiche comportant un profil interne apte à recevoir ledit corps de fiche du cordon et ayant des moyens de solidarisation du corps de fiche du cordon et de maintien en position inactive dudit verrou du corps de fiche du cordon ;
       ledit corps de presse-étoupe, le presse-étoupe au repos et ladite pièce de liaison définissant un passage interne suffisant pour permettre le passage du corps de la fiche du cordon ;
       le vissage du corps du presse-étoupe sur ladite pièce de liaison provoquant la compression dudit presse-étoupe et le serrage dudit presse-étoupe sur le cordon standard.To achieve this object, according to the invention, the plug device for standard electrical or optical connection cord provided at one end with a cord plug integral with the cord having a body comprising an external mechanical lock, is characterized in that said plug device includes:
    • a plug body;
    • a plug adapter separate from the plug body comprising external means for securing in said plug body;
    • a gland body having a cylindrical gland; and
    • a connecting piece having a first end for securing with said plug body and a second end provided with a screw thread for cooperating with a screw thread for said cable gland body;
    said plug adapter comprising an internal profile capable of receiving said cord plug body and having means for securing the cord plug body and holding said latch of the cord plug body in the inactive position;
    said cable gland body, the cable gland at rest and said connecting piece defining an internal passage sufficient to allow the body of the cord plug to pass;
    screwing the body of the cable gland onto said connecting piece causing compression of said cable gland and tightening of said cable gland on the standard cord.

    On comprend que grâce à l'invention, il est possible d'insérer la fiche du cordon dans l'ensemble des éléments constitutifs du dispositif de fiche pour amener le corps de la fiche dans l'adaptateur de fiche isolant. En outre, l'adaptateur de fiche est conformé de telle manière qu'il maintient le verrou mécanique de la fiche du cordon en position inactive. Ainsi, la liaison entre la fiche et l'embase correspondante est réalisée de façon classique simplement par le corps de fiche.It is understood that thanks to the invention, it is possible to insert the cord plug in all of the components of the plug to bring the plug body into the insulating plug adapter. In addition, the plug adapter is shaped so that it maintains the mechanical lock of the cord plug in the inactive position. Thus, the connection between the plug and the corresponding base is made of classic way simply by the plug body.

    Il faut également souligner que grâce à la compression du presse-étoupe, on obtient non seulement une étanchéité de l'ensemble du dispositif de fiche mais également la solidarisation mécanique entre le cordon standard et le dispositif de fiche qui complète la solidarisation principale résultant de la coopération de la fiche du cordon avec l'adaptateur de fiche.It should also be emphasized that thanks to the compression of the cable gland, not only does the whole assembly become watertight plug device but also the mechanical connection between the standard cord and the plug device which completes the connection main resulting from the cooperation of the cord plug with the plug adapter.

    Enfin et surtout, grâce à l'invention, il est possible d'adapter le cordon à un environnement industriel sans avoir à désolidariser la fiche du cordon. Ces avantages concernent aussi bien les cordons optiques que les cordons électriques.Finally and above all, thanks to the invention, it is possible to adapt the cord to an industrial environment without having to separate the plug from the cord. These advantages concern both optical cords and electrical cords.

    Selon un mode de réalisation préféré, ledit adaptateur de fiche isolant est constitué par deux pièces distinctes définissant chacune une partie du profil interne apte à recevoir ledit corps de la fiche du cordon, par quoi les deux pièces dudit adaptateur peuvent être mises en place successivement sur le corps de la fiche du cordon. According to a preferred embodiment, said plug adapter insulator consists of two separate parts, each defining a part of the internal profile capable of receiving said body of the cord plug, whereby the two parts of said adapter can be put in place successively on the body of the cord plug.

    On comprend que grâce à ce mode de réalisation préféré, le montage de la fiche du cordon dans l'adaptateur isolant, est facilité puisque chacune des pièces peut être mise en place successivement selon une direction latérale par rapport au corps de la fiche du cordon.It is understood that thanks to this preferred embodiment, the assembly of the cord plug in the insulating adapter is easy since each of the pieces can be placed successively according to a lateral direction relative to the body of the cord plug.

    De préférence encore, chaque pièce de l'adaptateur de fiche comporte un relief formant butée apte à coopérer avec une partie du verrou de la fiche du cordon lorsque ledit verrou est en position inactive. Cette caractéristique est particulièrement intéressante car ainsi, la solidarisation axiale de la fiche du cordon et de l'adaptateur de fiche est obtenue par une partie de la fiche qui a des dimensions normalisées. L'adaptateur de fiche pourra donc être utilisé quel que soit le type ou le fabriquant du cordon.More preferably, each piece of the plug adapter has a relief forming a stop capable of cooperating with part of the cord plug lock when said lock is in the inactive position. This characteristic is particularly interesting because thus, the axial connection of the cord plug and the plug adapter is obtained by a part of the file which has standardized dimensions. The plug adapter can therefore be used regardless of the type or manufacturer of the cord.

    D'autres caractéristiques et avantages de l'invention apparaítront mieux à la lecture de la description qui suit de plusieurs modes de réalisation de l'invention donnés à titre d'exemple non limitatifs.Other characteristics and advantages of the invention will appear better on reading the following description of several embodiments of the invention given by way of nonlimiting example.

    En se référant tout d'abord à la figure 2, on va décrire l'ensemble du dispositif de fiche selon l'invention.Referring first to Figure 2, we will describe the entire plug device according to the invention.

    Il comprend un corps de fiche 20, un adaptateur de fiche 22 pour la fiche 10 du cordon, qui est de préférence constitué par deux pièces distinctes 24 et 26, une pièce de liaison 28 et un corps de presse-étoupe 30 équipé d'un presse-étoupe 32 de forme cylindrique.It includes a plug body 20, a plug adapter 22 for plug 10 of the cord, which preferably consists of two separate parts 24 and 26, a connecting part 28 and a body of cable gland 30 fitted with a cylindrical cable gland 32.

    Le corps de fiche 20 peut avoir une forme quelconque et comporte intérieurement des moyens de solidarisation axiale et radiale de l'adaptateur de fiche 22. Il comporte en outre des moyens par baïonnette de connexion à un corps d'embase non représenté. Le corps de fiche 20 comporte en outre à sa partie postérieure 20a un taraudage.The plug body 20 can have any shape and internally comprises means for axially and radially securing the plug adapter 22. It further comprises means by bayonet of connection to a base body not shown. The plug body 20 further comprises at its rear part 20a a thread.

    La pièce de liaison 28 comporte une partie antérieure 28a et une partie postérieure 28b munies des filetages inversés 34 et 36.The connecting piece 28 has a front part 28a and a rear part 28b provided with reverse threads 34 and 36.

    Le corps de presse-étoupe 30 comprend un taraudage 38 et une paroi postérieure 40 percée d'un orifice axial de dimensions suffisantes pour permettre le passage de la fiche 12 du cordon 10.The gland body 30 includes a thread 38 and a rear wall 40 pierced with an axial opening of sufficient dimensions to allow passage of the plug 12 of the cord 10.

    De la même manière, la pièce de liaison 28 et le presse-étoupe 32 présentent un passage axial suffisant pour autoriser le passage de la fiche 12 du cordon 10.Similarly, the connecting piece 28 and the cable gland 32 has sufficient axial passage to allow the passage of the plug 12 of the cord 10.

    En se référant maintenant aux figures 3 à 6, on va décrire un mode préféré de réalisation de l'adaptateur de fiche 22 et la façon dont il est rendu solidaire de la fiche 12.Referring now to Figures 3 to 6, we will describe a preferred embodiment of the plug adapter 22 and how it is secured to sheet 12.

    L'adaptateur 22 peut être réalisé en un matériau isolant éventuellement métallisé avec un alliage de Nickel ou de Cadmium pour la protection électro-magnétique.The adapter 22 can be made of an insulating material possibly metallized with a nickel or cadmium alloy for the electro-magnetic protection.

    Les pièces 24 et 26 formant l'adaptateur 22 peuvent être solidaires entre elles par des organes de clipsage 42 et 44. Chaque pièce 24, 26 présente des profils internes 24a, 24b, qui, une fois les deux pièces assemblées, définissent un évidement 46 pour recevoir le corps de fiche 12 surmonté par une rainure 48 destinée à recevoir le levier de commande 18 de la fiche 12 lorsque celui-ci est en position abaissée correspondant à la désactivation du verrou 16.The parts 24 and 26 forming the adapter 22 can be joined together by clipping members 42 and 44. Each part 24, 26 has internal profiles 24a, 24b, which, once both assembled parts, define a recess 46 for receiving the body of plug 12 surmounted by a groove 48 intended to receive the lever control 18 of the plug 12 when the latter is in the lowered position corresponding to deactivation of latch 16.

    Comme le montre mieux la figure 5, chaque pièce 26 (24) comporte sur sa face antérieure 26b (24b) une extension 50 en forme de poutre qui fait saillie hors de la face antérieure. Les extensions 50 sont positionnées de telle manière que, lorsque le corps 14 de la fiche 12 est introduit dans l'évidement 46 de l'adaptateur 22 et lorsque le verrou 16 est en position désactivée, les extrémités 50a des extensions 50 soient en butée contre les verrous 16. C'est ce que montre mieux la figure 6.As best shown in Figure 5, each piece 26 (24) has on its front face 26b (24b) an extension 50 in the form of beam protruding from the anterior face. The extensions 50 are positioned so that when the body 14 of the plug 12 is introduced into the recess 46 of the adapter 22 and when the latch 16 is in the deactivated position, the ends 50a of the extensions 50 are in stop against the locks 16. This is best shown in FIG. 6.

    En se référant maintenant aux figures 2, 7, 8A et 8B, on va décrire le montage du dispositif de fiche sur la fiche 12 du cordon 10.Referring now to Figures 2, 7, 8A and 8B, we will describe the mounting of the plug device on plug 12 of cord 10.

    La pièce de liaison 28, le presse-étoupe 32 et le corps de presse-étoupe 30 sont engagés dans le cordon 10 au-delà de la fiche 12 comme cela est représenté sur la figure 2. Puis, après avoir rabattu le levier 18 du verrou 16 de la fiche 12, on monte la pièce 26 de l'adaptateur 22. Ensuite, on monte la deuxième pièce 24 de l'adaptateur sur le corps de fiche 14, ce qui provoque simultanément l'encliquetage des pièces 24 et 26. L'adaptateur 22 est alors fixé sur le corps 14 de la fiche 12, comme le montre la figure 7.The connecting piece 28, the cable gland 32 and the body of cable gland 30 are engaged in the cord 10 beyond the plug 12 as shown in Figure 2. Then, after folding the lever 18 of the lock 16 of the plug 12, the part 26 is mounted the adapter 22. Next, the second part 24 of the adapter is mounted on the plug body 14, which simultaneously causes the locking of the parts 24 and 26. The adapter 22 is then fixed on the body 14 of the plug 12, as shown in Figure 7.

    Ensuite, la fiche 12 et l'adaptateur 22 sont introduits dans le corps de fiche 20. De préférence, la paroi externe 24c, 26c de l'adaptateur comporte un bossage et la paroi interne 20b du corps de fiche 20 comporte quatre encoches décalées de 90 degrés. L'adaptateur 22 est ainsi immobilisé en rotation dans le corps de fiche 20 et il peut occuper une parmi quatre positions de codage.Then, the plug 12 and the adapter 22 are introduced into the plug body 20. Preferably, the external wall 24c, 26c of the adapter has a boss and the internal wall 20b of the plug body 20 has four notches offset by 90 degrees. The adapter 22 is thus immobilized in rotation in the plug body 20 and it can occupy one of four coding positions.

    Enfin, comme le montrent les figures 8A et 8B, la pièce de liaison 28 est vissée sur le corps de fiche 20, ce qui immobilise en translation l'adaptateur 22 par rapport au corps de fiche. Puis, le corps de presse-étoupe 30 est vissé sur le filetage 36 de la pièce de liaison, ce qui provoque la compression du presse-étoupe 32 et le serrage de celui-ci sur le cordon 10.Finally, as shown in Figures 8A and 8B, the workpiece link 28 is screwed onto the plug body 20, which immobilizes translation of the adapter 22 relative to the plug body. Then, the body of cable gland 30 is screwed onto the thread 36 of the connecting piece, which causes compression of the cable gland 32 and tightening of it on the cord 10.

    Il faut souligner que la fiche 12 est immobilisée en translation par rapport à l'adaptateur 22 du fait que les extrémités 50a des extensions 50 de l'adaptateur 22 viennent en butée sur le verrou 16 en position désactivée. Or, le verrou 16 a des cotes standard normalisés. Le dispositif de fiche selon l'invention peut donc être utilisé avec tous les cordons dont les fiches comportent un verrou conforme à cette norme.It should be noted that the sheet 12 is immobilized in translation relative to the adapter 22 because the ends 50a of the extensions 50 of the adapter 22 abuts on the latch 16 in position disabled. Now, the latch 16 has standardized standard dimensions. The device plug according to the invention can therefore be used with all cords including the files include a lock conforming to this standard.

    De préférence, la pièce de liaison 28 est munie sur sa deuxième extrémité d'un joint torique apte à coopérer avec ledit corps de presse-étoupe. Preferably, the connecting piece 28 is provided on its second end of an O-ring capable of cooperating with said body gland.

    En se référant maintenant aux figures 9 et 10, on va décrire un mode de réalisation du dispositif de fiche plus particulièrement adapté à un cordon optique.Referring now to Figures 9 and 10, we will describe a embodiment of the plug device more particularly adapted to an optical cord.

    Sur la figure 9, on a représenté en vue en perspective éclatée les différents éléments constitutifs du dispositif de fiche pour la version optique, ainsi que le cordon optique.In Figure 9, there is shown in exploded perspective view the various components of the plug device for the version optic, as well as the optical cord.

    Le cordon optique 60 a son extrémité qui est montée sur un corps de fiche de cordon 62 et solidarisée à celui-ci par une férule 64. Le corps de fiche du cordon comporte sur sa face externe un verrou mécanique 64 qui sera décrit ultérieurement plus en détail.The optical cord 60 has its end which is mounted on a cord plug body 62 and secured thereto by a ferrule 64. The cord plug body has a latch on its outer face mechanical 64 which will be described later in more detail.

    Le dispositif de fiche proprement dit comporte tout d'abord un corps de fiche 66 équipé sur sa face externe d'un écrou de solidarisation 67 avec l'élément conjugué de connexion optique. Le dispositif de fiche comporte également un adaptateur de fiche 68, 70 destiné à être monté dans le corps de fiche 66. Le dispositif de fiche comporte également une pièce tubulaire de connexion 72 dont une première extrémité est destinée à être rendue solidaire du corps de fiche 66 et dont l'autre extrémité 72b est destinée à être rendue solidaire d'un presse-étoupe non représenté sur la figure.The plug device itself comprises first of all a plug body 66 fitted on its external face with a fixing nut 67 with the combined optical connection element. The plug device also includes a plug adapter 68, 70 for mounting in the plug body 66. The plug device also includes a tubular connection piece 72, a first end of which is intended to be made integral with the plug body 66 and the other end of which 72b is intended to be secured to a cable gland not shown on the figure.

    En se référant maintenant à la figure 10A, on va décrire plus en détail le dispositif de fiche selon l'invention. Le corps de fiche 66 comporte, dans sa face interne 66a un épaulement 74 apte à coopérer avec un épaulement conjugué 76 ménagé dans la face externe de l'adaptateur 70, afin d'immobiliser celui-ci en translation vers l'avant. L'adaptateur 70 peut être immobilisé dans le corps de fiche 66 par la mise en place d'un système mécanique de verrouillage en translation 78.Referring now to FIG. 10A, we will describe more in detail the plug device according to the invention. The plug body 66 comprises, in its internal face 66a a shoulder 74 able to cooperate with a conjugated shoulder 76 formed in the external face of the adapter 70, in order to immobilize the latter in forward translation. The adapter 70 can be immobilized in the plug body 66 by putting in place of a mechanical locking system in translation 78.

    Comme on le voit sur cette figure, l'adaptateur 70 comporte un évidement axial 80 dont le contour permet l'insertion de l'extrémité du corps de fiche de cordon 62a. Ce profil définit également une rainure supérieure 80 pour permettre le passage du verrou mécanique 64 du corps de fiche du cordon optique. Plus précisément, comme le montre la figure 10A, l'extrémité du verrou 64 comporte une saillie 64a qui peut coopérer avec un épaulement 82 ménagé dans le passage axial 80 de l'adaptateur. La coopération de la saillie 64a et de l'épaulement 82 permet la solidarisation du corps de fiche 62 du cordon avec l'adaptateur. Il faut ajouter que l'épaulement 82 définit un profil tel que le verrou 64 est maintenu dans sa position désactivée.As seen in this figure, the adapter 70 has a axial recess 80 whose contour allows the insertion of the end of the cord plug body 62a. This profile also defines a groove upper 80 to allow the passage of the mechanical lock 64 of the plug body of the optical cord. More specifically, as shown in the FIG. 10A, the end of the latch 64 has a projection 64a which can cooperate with a shoulder 82 formed in the axial passage 80 of the adapter. The cooperation of the projection 64a and the shoulder 82 allows the attachment of the plug body 62 of the cord with the adapter. It is necessary add that the shoulder 82 defines a profile such that the latch 64 is held in its disabled position.

    La pièce de liaison 72 comporte, à sa première extrémité 72a, un taraudage apte à coopérer avec un filetage 86 ménagé à l'extrémité arrière du corps de fiche 66. La deuxième extrémité 72b de la pièce de liaison 72 définit un logement 88 de diamètre accru et un épaulement 90 destiné à recevoir un presse-étoupe 92. Ce presse-étoupe 92, au repos, comme représenté sur la figure 10A, présente un passage axial 94 permettant le libre-passage du corps de fiche 62 du cordon optique. Le dispositif de fiche comporte, enfin, un écrou de serrage 96 dont le taraudage 98 peut coopérer avec un filetage externe 100 prévu à l'extrémité 72b de la pièce de liaison 72. Cet écrou 76 présente un orifice axial 102 dont le diamètre, ou plus généralement les dimensions sont suffisantes pour permettre le libre-passage du corps de fiche 62 du cordon optique.The connecting piece 72 has, at its first end 72a, a thread capable of cooperating with a thread 86 formed at the end rear of the plug body 66. The second end 72b of the piece of link 72 defines a housing 88 of increased diameter and a shoulder 90 intended to receive a cable gland 92. This cable gland 92, at rest, as shown in FIG. 10A, has an axial passage 94 allowing the free passage of the plug body 62 of the optical cord. The plug device comprises, finally, a tightening nut 96, the internal thread 98 can cooperate with an external thread 100 provided for the end 72b of the connecting piece 72. This nut 76 has an orifice axial 102 whose diameter, or more generally the dimensions are sufficient to allow free passage of the plug body 62 of the cord optical.

    L'utilisation du dispositif de fiche destiné à être monté sur la fiche 62 du cordon optique 60 est le suivant. Dans un premier temps, la pièce de liaison 72, le presse-étoupe 92 et l'écrou de serrage 96 sont remontés autour du cordon optique 66. Puis, la partie avant 62a du corps de fiche 62 est engagé dans le passage axial 80 de l'adaptateur 70, le verrou mécanique 64 étant abaissé en position inactive. Après l'insertion du corps de fiche de cordon dans l'adaptateur 70, le verrou 64, grâce à sa partie en saillie 64a coopérant avec l'épaulement 62, assure la solidarisation du corps de fiche de cordon et de l'adaptateur. Cet ensemble est mis en place dans le corps de fiche 70 et immobilisé par l'insertion du dispositif de verrouillage en translation 78. Dans une étape ultérieure, la pièce de liaison 72 est vissée sur la partie arrière du corps de fiche 66. Enfin, l'écrou 66 est vissé sur l'extrémité arrière 72b de la pièce de liaison 72 pour provoquer la déformation du presse-étoupe 92 qui vient ainsi serrer la face externe 60a du cordon optique 60. On obtient ainsi, non seulement l'étanchéité du volume interne défini par la pièce de liaison 72 et le corps de fiche 66, mais également la solidarisation mécanique du cordon optique 60 avec le dispositif de fiche, grâce au serrage mentionné précédemment. La figure 10B montre le dispositif de fiche monté sur la fiche 62 du cordon optique 60.The use of the plug device intended to be mounted on the plug 62 of the optical cord 60 is as follows. At first, the connecting piece 72, the cable gland 92 and the clamping nut 96 are wound up around the optical cord 66. Then, the front part 62a of the body plug 62 is engaged in the axial passage 80 of the adapter 70, the mechanical lock 64 being lowered to the inactive position. After insertion of the cord plug body in the adapter 70, the lock 64, thanks to its projecting part 64a cooperating with the shoulder 62, ensures the securing the cord plug body and the adapter. This set is placed in the plug body 70 and immobilized by the insertion of the translational locking device 78. In a subsequent step, the connecting piece 72 is screwed onto the rear part of the plug body 66. Finally, the nut 66 is screwed onto the rear end 72b of the connecting piece 72 to cause the deformation of the cable gland 92 which thus comes tighten the outer face 60a of the optical cord 60. This gives, not only the tightness of the internal volume defined by the connecting piece 72 and the plug body 66, but also the mechanical connection of the optical cord 60 with the plug device, thanks to the mentioned tightening previously. Figure 10B shows the plug device mounted on the plug 62 of the optical cord 60.
