Abstract

The locking mechanism structure has an outer locking ring with a flexible arm section (31) which slides forward on an outer cylindrical section of the male part (6) of the connector. In the released locking mechanism position, the male section slides onto the corresponding female part, and an inner indent (21) in the outer section click fits into a corresponding female part. The outer locking ring pushes forward to prevent flexure and thus release of the outer cylindrical section.

Dans la mesure où la réalisation du contact 4 et de l'isolant 5 n'entre pas dans le cadre de la présente invention, ces éléments sont représentés très schématiquement sur les figures 2 à 6 et ne sont pas représentés du tout sur la figure 1.The first connector part 1 comprises a housing 3 of essentially cylindrical shape in which (at least) a contact 4 female is held in place with insulation 5 shown as formed of two parts. Insofar as the making of contact 4 and of insulation 5 is not within the scope of the present invention, these elements are shown very schematically in Figures 2 to 6 and are not shown at all in Figure 1.

    De façon correspondante, la seconde partie de connecteur 2 comprend un boítier 6 de forme essentiellement cylindrique dans lequel (au moins) un contact 7 mâle est maintenu à l'aide d'un isolant 8 représenté schématiquement comme étant formé de deux parties.Correspondingly, the second connector part 2 comprises a housing 6 of essentially cylindrical shape in which (at least) a male contact 7 is maintained using an insulator 8 shown schematically as being formed of two parts.

    Les boítiers 3 et 6 des deux parties de connecteur 1 et 2 comportent des sections antérieures d'emboítement 9, 10, respectivement, de forme générale cylindrique, la section d'emboítement 9 du boítier 3 étant destinée à s'emboíter dans la section d'emboítement 10 du boítier 6 lors de l'accouplement du connecteur.Boxes 3 and 6 of the two connector parts 1 and 2 have anterior interlocking sections 9, 10, respectively, of generally cylindrical shape, the section socket 9 of the housing 3 being intended to fit into the interlocking section 10 of the housing 6 during the coupling of the connector.

    La section d'emboítement 9 du boítier 3 porte extérieurement trois clavettes de détrompage 11 axiales, décalées de 120° les unes par rapport aux autres, chaque clavette 11 présentant un flanc antérieur et un flanc postérieur obliques de telle manière que la clavette 11 présente dans son ensemble une forme trapézoïdale. Par ailleurs, trois segments de gorge 12 sont prévus dans la surface extérieure du tronçon d'emboítement 9, chaque segment de gorge 12 étant situé angulairement entre deux clavettes 11.The interlocking section 9 of the housing 3 externally carries three 11 axial keying pins, offset by 120 ° each compared to the others, each key 11 having an anterior flank and an oblique posterior side so that the key 11 as a whole has a trapezoidal shape. In addition, three groove segments 12 are provided in the outer surface of the interlocking section 9, each groove segment 12 being located angularly between two keys 11.

    La section d'emboítement 10 du boítier 6 présente intérieurement trois rainures axiales 13 réparties angulairement à 120° les unes des autres, ces rainures 13 étant destinées à recevoir les clavettes 11 de la section 9 du boítier 3, à des fins de détrompage. Chaque rainure 13 qui commence à l'extrémité antérieure de la section d'emboítement 10, débouche dans un évidement 14 en forme de T qui traverse la paroi de la section 10, de telle manière que la rainure 13 se trouve en alignement avec la barre axiale 14a du T. Tel que cela apparaít surtout sur la figure 1, la barre axiale 14a de l'évidement 14 est élargie, avant de déboucher à la surface extérieure de la section 10, pour constituer ainsi sur chaque côté un gradin 15 qui est délimité, en direction de l'extrémité antérieure de la section 10, à l'endroit de la barre transversale 14b de l'évidement 14 en T, par un rebord 16. Comme le montre la figure 1, le rebord 16 présente un flanc postérieur 17 plan, perpendiculaire à l'axe de la section 10, et un flanc antérieur 18 arrondi.The interlocking section 10 of the housing 6 has internally three axial grooves 13 angularly distributed at 120 ° from each other others, these grooves 13 being intended to receive the keys 11 of the section 9 of the housing 3, for polarization purposes. Each groove 13 which begins at the anterior end of the interlocking section 10, opens into a T-shaped recess 14 which crosses the wall of section 10, so that the groove 13 is in alignment with the axial bar 14a of the T. As it appears above all in FIG. 1, the axial bar 14a of the recess 14 is widened, before lead to the outside surface of section 10, to constitute thus on each side a step 15 which is delimited, in the direction of the front end of section 10, at the place of the bar transverse 14b of the recess 14 in T, by a flange 16. As the shows FIG. 1, the rim 16 has a plane rear flank 17, perpendicular to the axis of section 10, and an anterior flank 18 round.

    La section d'emboítement 10 comporte par ailleurs, dans des positions angulaires intermédiaires entre chaque fois deux évidements 14, une patte 19 s'étendant en porte-à-faux, dans l'épaisseur de la section 10, en direction de l'extrémité antérieure de cette dernière, de manière à pouvoir fléchir élastiquement, radialement vers l'intérieur et vers l'extérieur. A son extrémité libre, la patte 19 comporte une tête 20 dont la dimension radiale est supérieure à l'épaisseur (radiale) de la section 10. La tête 20 constitue ainsi un plot intérieur 21 qui fait saillie vers l'intérieur sur la surface intérieure de la section 10 et un plot extérieur 22 qui fait saillie sur la surface extérieure de la section 10. Sur sa surface extérieure, la patte 19 comporte une rampe 23 qui se termine par un épaulement 24 sur le côté tourné vers la tête 20.The interlocking section 10 also comprises, in angular positions intermediate between each two recesses 14, a tab 19 extending in overhang, in the thickness of the section 10, towards the anterior end of the latter, so as to be able to flex elastically, radially inwards and outwards. At its free end, the tab 19 has a head 20, the radial dimension of which is greater than the (radial) thickness of the section 10. The head 20 thus constitutes an internal stud 21 which makes inward projection on the inner surface of section 10 and a external stud 22 which projects from the external surface of the section 10. On its outer surface, the tab 19 has a ramp 23 which is ends with a shoulder 24 on the side facing the head 20.

    Enfin, tel que cela apparaít sur la figure 1, la section d'emboítement 10 du boítier 6 est munie extérieurement, dans sa zone postérieure, d'une partie annulaire 25 de diamètre extérieur accru, interrompue en trois endroits décalés de 120° les uns par rapport aux autres, par des parties 26 situées chacune à l'arrière d'un des évidements 14, et s'étendant sur une largeur circonférentielle va en diminuant depuis l'extrémité postérieure de la barre axiale 14a de l'évidement 14 en T vers l'arrière du boítier 6, pour se terminer, à l'endroit de l'épaulement 27 constituant l'extrémité postérieure de la section 10, par un isthme 28 dont la largeur circonférentielle correspond à la largeur circonférentielle de la barre axiale 14a de l'évidement 14 au niveau des gradins 15.Finally, as shown in Figure 1, the section socket 10 of the housing 6 is provided externally, in its zone posterior, of an annular portion 25 of increased outside diameter, interrupted in three places offset by 120 ° from each other others, by parts 26 each located at the rear of one of the recesses 14, and extending over a circumferential width goes in decreasing from the rear end of the axial bar 14a by the recess 14 in T towards the rear of the housing 6, to end, at the location of the shoulder 27 constituting the rear end of the section 10, by an isthmus 28 whose circumferential width corresponds to the circumferential width of the axial bar 14a of the recess 14 at the steps 15.

    La section d'emboítement 10 du boítier 6 de la partie de connecteur 2 reçoit extérieurement une bague de verrouillage 29 qui présente intérieurement trois segments de gorge 30 répartis à 120° les uns des autres et trois languettes 31 s'étendant en porte-à-faux en direction de l'extrémité antérieure de la bague 29, en étant inclinées vers l'intérieur de la bague. Chaque languette 31 présente une largeur circonférentielle légèrement inférieure à la largeur circonférentielle que la barre axiale 14a de l'évidement 14 présente au niveau des gradins 15 (et donc légèrement inférieure à la largeur circonférentielle de l'isthme 28) et comporte, au milieu de sa largeur, un bossage intérieur 32 qui apparaít en particulier sur les figures 2b à 6b. A son bord postérieur, chaque segment de gorge 30 comporte un segment de bourrelet intérieur 33.The fitting section 10 of the housing 6 of the connector part 2 externally receives a locking ring 29 which has internally three groove segments 30 distributed at 120 ° from each other others and three tongues 31 extending in a cantilever direction the anterior end of the ring 29, being inclined towards the inside of the ring. Each tongue 31 has a circumferential width slightly less than the circumferential width than the axial bar 14a of the recess 14 present at the steps 15 (and therefore slightly less than the circumferential width of the isthmus 28) and comprises, at middle of its width, an interior boss 32 which appears in particular in Figures 2b to 6b. At its posterior edge, each throat segment 30 includes an inner bead segment 33.

    Pour la cinématique d'accouplement du connecteur tel que décrit précédemment, on va se référer aux figures 2a, 2b à 6a, 6b, les figures 2a à 6a étant des sections axiales dans un plan passant au niveau d'un des gradins 15 et par un des rebords 16 du boítier 6, donc d'un côté de la barre axiale 14a d'un évidement 14 et d'une clavette 11 et d'un côté du bossage médian 32 d'une languette 31 de la bague de verrouillage 29, tandis que les figures 2b à 6b sont des sections partielles correspondantes dans un plan passant par le milieu de la barre axiale 14a d'un évidement 14 du boítier 6, donc par le bossage médian 32 d'une languette 31 de la bague de verrouillage 29 et par l'une des clavettes 11 du boítier 3.For the coupling kinematics of the connector as described previously, we will refer to Figures 2a, 2b to 6a, 6b, Figures 2a to 6a being axial sections in a plane passing at one of the bleachers 15 and by one of the edges 16 of the housing 6, therefore on one side of the axial bar 14a with a recess 14 and a key 11 and on one side of the median boss 32 of a tongue 31 of the locking ring 29, while Figures 2b to 6b are corresponding partial sections in a plane passing through the middle of the axial bar 14a of a recess 14 of the housing 6, therefore by the median boss 32 of a tongue 31 of the locking ring 29 and by one of the keys 11 of the housing 3.

    La bague de verrouillage 29 est montée sur la section d'emboítement 10 du boítier 6 de telle manière qu'un plat 34 axial en saillie vers l'intérieur de la bague 29 en arrière d'une languette 31 vienne se placer dans un isthme 28 et que la languette 31 correspondante vienne s'encliqueter dans les gradins 15, derrière le rebord 16 de l'évidement 14 correspondant. Cela apparaít clairement sur la figure 2a.The locking ring 29 is mounted on the nesting section 10 of the housing 6 so that an axial flat 34 projecting towards the inside of the ring 29 behind a tongue 31 is placed in an isthmus 28 and that the corresponding tongue 31 comes snap into the stands 15, behind the edge 16 of the recess 14 corresponding. This is clearly shown in Figure 2a.

    Pour accoupler la partie de connecteur 1 avec la partie de connecteur 2 dont la bague de verrouillage 29 se trouve encliquetée dans cette position, on emboíte la section 9 de la partie de connecteur 1 dans la section 10 de la partie de connecteur 2, les clavettes 11 assurant le détrompage en combinaison avec les rainures 13. Dès que l'extrémité antérieure de la section 9 atteint les têtes 20 des pattes 19, ces dernières fléchissent vers l'extérieur, leurs plots extérieurs 22 pénétrant dans les segments de gorge 30 de la bague 29 (voir figures 3a et 3b). Cela provoque le blocage de la bague de verrouillage 29 sur la section 10 du boítier 6.To couple the connector part 1 with the connector part 2, the locking ring 29 is snapped into this position, we fit section 9 of the connector part 1 in the section 10 of the connector part 2, the keys 11 ensuring the coding in combination with grooves 13. As soon as the end front of section 9 reaches the heads 20 of the legs 19, the latter bend outwards, their external studs 22 penetrating into the groove segments 30 of the ring 29 (see Figures 3a and 3b). That causes the locking ring 29 to block on section 10 of the housing 6.

    Au cours de la poursuite du mouvement d'emboítement, chaque clavette 11, en atteignant le bossage 32 d'une languette 31, repousse cette dernière vers l'extérieur (figure 4b), ce qui supprime l'effet de rétention de la bague 9 par les languettes 31 et les rebords 16 (voir figure 4a).During the continuation of the nesting movement, each key 11, reaching the boss 32 of a tongue 31, pushes this last outward (Figure 4b), which removes the retention effect of the ring 9 by the tongues 31 and the flanges 16 (see FIG. 4a).

    Lorsque les sections 9 et 10 des deux boítiers 3 et 6 sont emboítées à fond l'une dans l'autre, les plots intérieurs 21 des pattes 19 se trouvent au droit des segments de gorge 12 et se détendent élastiquement dans ces derniers, ce qui produit l'encliquetage de la section 10 sur la section 9. Dans cette position, comme le montre la figure 5b, les languettes 31 de la bague de verrouillage 29 restent toujours repoussées vers l'extérieur sous l'action des clavettes 11.When sections 9 and 10 of the two boxes 3 and 6 are fitted to one inside the other, the interior studs 21 of the legs 19 are located throat segments 12 right and expand elastically in these last, which produces the snap of section 10 on section 9. In this position, as shown in Figure 5b, the tabs 31 of the locking ring 29 always remains pushed outwards under the action of the keys 11.

    Pour verrouiller le connecteur dans cette position d'emboítement, on pousse la bague de verrouillage 29 (vers la gauche sur les figures 5a et 5b) en direction de la partie de connecteur 1, de sorte que les segments de bourrelet 33 de la bague 29 montent sur les rampes 23 des pattes 19 jusqu'à s'engager derrière les épaulements 24. En même temps, les bossages 32 des languettes 31 de la bague 29 franchissent les clavettes 11, ce qui permet aux languettes 31 de se détendre élastiquement vers l'intérieur, les bossages 32 venant se placer derrière les clavettes 11 (voir figures 6a et 6b). La bague de verrouillage 29 est ainsi maintenue dans cette position axiale et verrouille les sections d'emboítement 9 et 10 des deux boítiers 3 et 6 des parties de connecteur 1 et 2 dans la position d'encliquetage, c'est-à-dire d'accouplement. To lock the connector in this nesting position, pushes the locking ring 29 (to the left in FIGS. 5a and 5b) in the direction of the connector part 1, so that the segments of bead 33 of the ring 29 rise on the ramps 23 of the legs 19 until engaging behind the shoulders 24. At the same time, the bosses 32 of the tongues 31 of the ring 29 cross the keys 11, which allows the tabs 31 to relax elastically towards inside, the bosses 32 coming to be placed behind the keys 11 (see Figures 6a and 6b). The locking ring 29 is thus held in this axial position and locks the interlocking sections 9 and 10 of two housings 3 and 6 of the connector parts 1 and 2 in the position latching, that is to say coupling.

    Le connecteur tel qu'illustré par les figures 7 à 11, diffère du connecteur suivant les figures 1 à 6 principalement par une dissociation des différentes fonctions, de manière que chaque partie constitutive puisse être conçue de façon optimale pour assumer les fonctions qui lui sont attribuées. En l'occurence, ce sont surtout les fonctions de blocage de la bague de verrouillage et d'encliquetage des deux boítiers qui sont assumées par des organes faisant partie, non pas du boítier d'une des parties de connecteur, mais d'un élément supplémentaire rapporté sur ce boítier.The connector as illustrated in figures 7 to 11, differs from connector according to Figures 1 to 6 mainly by dissociation different functions, so that each component part can be optimally designed to assume the functions that are assigned. In this case, it is mainly the blocking functions of the locking and latching ring of the two housings which are assumed by bodies that are part of, not part of, one of the connector parts but of an additional element reported on this housing.

    La première partie de connecteur ou partie femelle 101 et la deuxième partie de connecteur ou partie mâle 102 présentent, l'un un boítier 103 dans lequel au moins un contact femelle 104 est monté à l'aide d'un isolant 105 et l'autre un boítier 106 dans lequel au moins un contact mâle 107 est monté à l'aide d'un isolant 108. Le boítier 103 de la partie de connecteur 101 comporte une section antérieure d'emboítement 109 et le boítier 106 de la partie de connecteur 102 comporte une section antérieure d'emboítement 110 destinée à s'emboíter sur la section 109.The first connector part or female part 101 and the second connector part or male part 102 have, one a housing 103 in which at least one female contact 104 is mounted using an insulator 105 and the other a housing 106 in which at least one contact male 107 is mounted using an insulator 108. The housing 103 of the part of connector 101 has an anterior interlocking section 109 and the housing 106 of connector part 102 has a section anterior socket 110 intended to fit onto section 109.

    Selon la figure 7, la section d'emboítement 109 du boítier 103 présente une unique clavette axiale de détrompage 111 et trois segments de gorge 112 décalés de 120° les uns par rapport aux autres.According to Figure 7, the nesting section 109 of the housing 103 has a single axial key 111 and three segments throat 112 offset by 120 ° with respect to each other.

    La section d'emboítement 110 du boítier 106 présente intérieurement une rainure axiale 113 coopérant avec la clavette 111 en vue du détrompage. La section d'emboítement 110 est traversée radialement par six trous de passage 114a, 114b quadrangulaires répartis à 60° les uns des autres et présente, dans le plan desdits trous de passage, une gorge circulaire 114c extérieure. A l'arrière de cette gorge, on retrouve, sur la section d'emboítement 110, une partie annulaire 125 de diamètre extérieur accru interrompue en trois endroits décalés de 120°, derrière chaque trou 114a, par une partie 126 qui diminue de largeur circonférentielle vers l'arrière et se termine au niveau d'un épaulement d'extrémité 127, par un isthme 128.The interlocking section 110 of the housing 106 has internally an axial groove 113 cooperating with the key 111 for the purpose of foolproof. The interlocking section 110 is crossed radially by six through holes 114a, 114b quadrangular distributed at 60 ° from each other other and has, in the plane of said through holes, a groove exterior circular 114c. At the back of this gorge, we find, on the socket section 110, an annular part 125 of outside diameter increased interrupted in three places offset by 120 °, behind each hole 114a, by a part 126 which decreases in circumferential width towards the rear and ends at an end shoulder 127, with a isthmus 128.

    Une gorge extérieure 115 est par ailleurs prévue dans la section d'emboítement 110, entre la gorge 114c et l'extrémité antérieure de cette section 110.An outer groove 115 is also provided in the section socket 110, between the groove 114c and the anterior end of this section 110.

    Un jonc 116, c'est-à-dire un anneau fendu, comportant deux fois trois plots 117 et 118 décalés à 60° les uns des autres, est rapporté dans la gorge 114c. Les plots 117 qui altement avec les plots 118 font saillie vers l'intérieur sur le jonc 116, tandis que les plots 118 font saillie sur le jonc 116 à la fois vers l'intérieur et vers l'extérieur.A rod 116, that is to say a split ring, comprising two times three studs 117 and 118 offset 60 ° from each other, is reported in the throat 114c. The studs 117 which alternately with the studs 118 project towards the interior on the rod 116, while the studs 118 protrude on the rod 116 both inward and outward.

    La bague de verrouillage 129 comporte intérieurement une gorge 130, trois languettes 131 décalées à 120° l'une de l'autre et s'étendant en porte-à-faux en direction de l'extrémité antérieure en étant inclinées vers l'intérieur, un bourrelet 133 de délimitation de la gorge 130 vers l'arrière, ainsi qu'un plat 134 en saillie vers l'intérieur à l'arrière de chaque languette 131.The locking ring 129 has an internal groove 130, three tabs 131 offset 120 ° from one another and extending in overhang towards the anterior end while being inclined towards inside, a bead 133 delimiting the groove 130 towards the rear, as well as a dish 134 projecting inwards at the rear of each tongue 131.

    Le jonc 116 est monté dans la gorge 114c de manière qu'un plot 117 faisant saillie sur le jonc 116 uniquement vers l'intérieur se trouve dans chaque trou 114a situé en avant d'une zone d'interruption 126 de la partie 125, et qu'un plot 118 se trouve dans chaque trou 114b. Ensuite, la bague de verrouillage 129 est montée sur la section d'emboítement 110 du boítier 106 déjà équipé du jonc 116 de manière qu'une languette 131 vienne se placer au droit d'un plot 117 et vienne s'encliqueter, lorsque la bague de verrouillage 129 est en position entièrement reculée, les plats 134 se trouvant dans les isthmes 128, derrière le flanc antérieur de la gorge 114c, au-dessus d'un plot 117.The rod 116 is mounted in the groove 114c so that a stud 117 protruding from the rod 116 only inwards is in each hole 114a situated in front of an interruption zone 126 of the part 125, and that a stud 118 is located in each hole 114b. Then the ring locking device 129 is mounted on the socket section 110 of the housing 106 already equipped with the rod 116 so that a tongue 131 come to the right of a stud 117 and snap, when the locking ring 129 is in the fully retracted position, the dishes 134 located in the isthmus 128, behind the anterior flank of the groove 114c, above a stud 117.

    Cela assure, comme le montre la figure 8, la rétention de la bague de verrouillage 129 en position reculée inactive sur le boítier 106. Le jonc 116 étant monté sous précontrainte dans la gorge 114c, il se resserre par élasticité et enfonce les plots 117, 118 à fond dans les trous 114a, 114b.This ensures, as shown in Figure 8, the retention of the ring locking 129 in the inactive retracted position on the housing 106. The ring 116 being mounted under preload in the groove 114c, it tightens by elasticity and pushes the studs 117, 118 fully into the holes 114a, 114b.

    Lors de l'emboítement des deux sections 109, 110 des boítiers 103 et 106, l'extrémité antérieure de la section 109, en atteignant les plots 117 et 118, repousse ces derniers vers l'extérieur, ce qui fait que, comme le montre la figure 9, les plots 117 font fléchir vers l'extérieur les languettes 131 de la bague 129, les décrochant ainsi de la gorge 114c. Simultanément, les plots 118 sont repoussés vers l'extérieur dans la gorge 130 de la bague 129 et bloquent ainsi la bague 129 sur le boítier 106.When the two sections 109, 110 of the housings 103 and 106, the anterior end of section 109, reaching studs 117 and 118, pushes these outwards, which means that, like the shown in Figure 9, the studs 117 flex the tabs outward 131 of the ring 129, thus unhooking them from the groove 114c. Simultaneously, the studs 118 are pushed outwards into the groove 130 of the ring 129 and thus block the ring 129 on the housing 106.

    Lors de la poursuite du mouvement d'emboítement, les plots 118 atteignent finalement les segments de gorge 112 de la section d'emboítement 109 du boítier 103 et s'engagent élastiquement vers l'intérieur dans ces segments 112, avec effet d'encliquetage des deux sections 109 et 110 l'une sur l'autre, comme représenté sur la figure 10. En même temps, le blocage de la bague de verrouillage 129 en position arrière sur le boítier 106 est supprimé.When continuing the nesting movement, the studs 118 finally reach the throat segments 112 of the section socket 109 of the housing 103 and engage elastically towards the interior in these segments 112, with ratcheting effect of the two sections 109 and 110 on top of each other, as shown in Figure 10. At the same time, locking the locking ring 129 in position rear on the housing 106 is deleted.

    Il est alors possible de pousser la bague de verrouillage 129 en direction du boítier 103 (vers la gauche sur le dessin), ce qui fait que les plots 118 sont maintenus enfoncés dans les segments de gorge 112 par la bague 129 et que les languettes 131 s'engagent élastiquement dans la gorge 115 de la section 110 du boítier 106. La bague 129 se trouve ainsi maintenue en position de verrouillage des deux boítiers 103, 106 l'un par rapport à l'autre et ne peut être reculée que moyennant une action intentionnelle vers l'arrière (vers la droite sur le dessin).It is then possible to push the locking ring 129 in direction of the housing 103 (to the left in the drawing), which means that the studs 118 are held pressed into the groove segments 112 by the ring 129 and that the tabs 131 engage elastically in the groove 115 of section 110 of the housing 106. The ring 129 is thus maintained in the locking position of the two housings 103, 106 one by relationship to the other and can only be reversed with an action intentional backwards (to the right in the drawing).

    Dans les deux modes de réalisation représentés et décrits, toutes les parties du connecteur relevant de la présente invention (les boítiers des deux parties de connecteur, la bague de verrouillage et, le cas échéant, le jonc rapporté) peuvent être réalisées par moulage en matière plastique, sans nécessiter aucune reprise d'usinage.In the two embodiments shown and described, all of the parts of the connector of the present invention (the housings of the two connector parts, the locking ring and, if necessary, the rod) can be made by plastic molding, without requiring any further machining.

    Dans le cas où le connecteur doit être un connecteur blindé, il est possible de métalliser les parties constitutives en matière plastique, sans que cela n'altère en aucune manière leur fonction première.In the case where the connector must be a shielded connector, it is possible to metallize the plastic parts, without that this in no way alters their primary function.

    En position avancée (verrouillage) de la bague de verrouillage 29, 129, il est possible de faire tourner cette dernière, par exemple d'une dizaine de degrés, ce qui permet de s'assurer que le verrouillage est bien réalisé. Ce n'est qu'en position avancée qu'une telle rotation est possible du fait de la largeur circonférentielle des zones d'interruption 26, 126 de la partie 25, 125 du boítier 6, 106, alors qu'elle est empêchée en position reculée de la bague, grâce aux plats 34, 134 qui se trouvent alors immobilisés angulairement dans les isthmes 28, 128 des zones d'interruption 26, 126.In the advanced position (locking) of the locking ring 29, 129, it is possible to rotate the latter, for example by a ten degrees, which ensures that the locking is secure executed. It is only in the advanced position that such rotation is possible due to the circumferential width of the interruption zones 26, 126 of the part 25, 125 of the housing 6, 106, while it is prevented in position moved back from the ring, thanks to the plates 34, 134 which are then angularly immobilized in the isthmus 28, 128 of the zones 26, 126.

    Dans les deux modes de réalisation représentés et décrits, un joint 35, 135 disposé à l'intérieur de la section d'emboítement 10, 110 du boítier 6, 106 de la seconde partie de connecteur 2, 102 et comprimé par l'extrémité antérieure de la section d'emboítement 9, 109 du boítier 3, 103 de la première partie de connecteur 1, 101 assure, en fin d'emboítement des deux parties de connecteur (verrouillage), à la fois l'étanchéité du connecteur et, par son effet de rappel élastique, la compensation des jeux et l'absence de toute possibilité de vibrations.In the two embodiments shown and described, a seal 35, 135 arranged inside the interlocking section 10, 110 of the housing 6, 106 of the second connector part 2, 102 and compressed by the front end of the interlocking section 9, 109 of the housing 3, 103 of the first connector part 1, 101 ensures, at the end of nesting of the two connector parts (locking), both the sealing of the connector and, by its elastic return effect, the clearance compensation and the absence of any possibility of vibrations.

    Enfin, les deux parties de connecteur 1 et 2, au lieu de comporter la première au moins un contact femelle et la seconde au moins un contact mâle, pourraient également comporter la première au moins un contact mâle et la seconde au moins un contact femelle, ou toutes les deux des contacts des deux types. Dans tous les cas, la bague de verrouillage est montée sur le boítier d'une partie de connecteur qui est mobile, l'autre partie pouvant être fixe.Finally, the two connector parts 1 and 2, instead of comprising the first at least one female contact and the second at least one contact male, could also include the first at least one contact male and the second at least one female contact, or both contacts of both types. In all cases, the locking ring is mounted on the housing of a connector part which is mobile, the other part can be fixed.
