Abstract

The invention concerns a connection formed by two articulated sub-assemblies (26, 28) for mounting and dismounting a removable rear connection on a connector (10) provided or not with wiring, without disassembling the latter. The sub-assembly (26) comprises a collar in at least two parts (36a, 36b) capable of being urged onto the connector (10) rear. The sub-assembly (28) forms a ring in at least two parts (56a, 56b) designed to enclose simultaneously the connector (10) rear and the collar. The ring co-operates with the connector by means of threads (20, 60) and with the collar by a ring-shaped groove-rib assembly (54). Moreover, the sub-assembly (26) is locked in rotation relative to the connector (10).

Description

RACCORD ARRIERE AMOVIBLE POUR UN CONNECTEUR TEL QU'UN CONNECTEUR ELECTRIQUE CIRCULAIRE REMOVABLE REAR CONNECTION FOR A CONNECTOR SUCH AS A CIRCULAR ELECTRIC CONNECTOR
DESCRIPTIONDESCRIPTION
Domaine techniqueTechnical area
L'invention concerne un raccord arrière conçu pour être assemblé à un connecteur, du côté du câblage, afin de doter ce connecteur d'un accessoire destiné par exemple à maintenir les câbles et/ou à assurer une étanchéité.The invention relates to a rear connector designed to be assembled with a connector, on the wiring side, in order to provide this connector with an accessory intended for example to hold the cables and / or to ensure a seal.
Dans l'ensemble du texte, les termes "arrière" et "avant" seront utilisés en prenant pour convention que l'arrière du connecteur correspond au côté sur lequel sont raccordés les câbles.Throughout the text, the terms "rear" and "front" will be used, assuming that the rear of the connector corresponds to the side to which the cables are connected.
Le raccord arrière amovible conforme à l'invention peut être utilisé sur tout connecteur comportant une section arrière filetée. Les connecteurs électriques multi-conducteurs de forme cylindrique, généralement appelés "connecteurs circulaires", appartiennent à cette catégorie. Le raccord conforme à l'invention peut toutefois être utilisé sur d'autres types de connecteurs tels que des connecteurs à fibres optiques, des connecteurs mixtes, etc..The removable rear connector according to the invention can be used on any connector comprising a threaded rear section. Multi-conductor cylindrical electrical connectors, generally called "circular connectors", belong to this category. The connector according to the invention can however be used on other types of connectors such as fiber optic connectors, mixed connectors, etc.
Etat de la techniqueState of the art
La plupart des connecteurs électriques existants sont équipés d'une section arrière filetée permettant de leur adjoindre un raccord arrière amovible. Ce raccord, qui constitue un accessoire du connecteur, est généralement appelé "serre-câbles", du fait que sa fonction principale est, le plus souvent, le maintien des câbles selon une orientation déterminée à proximité immédiate du connecteur.Most existing electrical connectors are equipped with a threaded rear section allowing them to add a removable rear connector. This connector, which is an accessory to the connector, is generally called "cable clamp", because its main function is, most often, maintaining the cables in a determined orientation in the immediate vicinity of the connector.
Les raccords arrières existants comprennent une bague formant écrou, prévue pour être vissée sur la section arrière filetée du connecteur. Cette bague porte, par l'intermédiaire d'une ou plusieurs branches, un système de maintien des câbles formé par exemple de deux demi-brides aptes à être serrées l'une contre l'autre au moyen de vis. Les branches qui relient la bague au système de maintien des câbles sont conformées pour donner aux câbles l'orientation souhaitée. Ainsi, les câbles peuvent être maintenus dans l'axe du connecteur ou selon une orientation coudée par rapport à cet axe, par exemple à 45° ou à 90°. Quelle que soit la forme qui leur est donnée, tous les raccords arrière amovibles existants comprennent une bague réalisée d'un seul tenant. Par conséquent, ces raccords doivent impérativement être enfilés sur les câbles avant que les extrémités de ces derniers ne soient raccordées sur le connecteur. En effet, tout oubli est sanctionné par la nécessité de déconnecter totalement les câbles du connecteur, puis de les raccorder à nouveau après insertion du raccord. En plus de la perte de temps induite par une telle opération, le risque d'erreur dû à un câblage erroné s'en trouve augmenté.Existing rear fittings include a nut ring, which is intended to be screwed onto the threaded rear section of the connector. This ring carries, via one or more branches, a cable retention system formed for example of two half-flanges capable of being tightened against one another by means of screws. The branches which connect the ring to the cable retention system are shaped to give the cables the desired orientation. Thus, the cables can be held in the axis of the connector or in a bent orientation relative to this axis, for example at 45 ° or 90 °. Whatever shape they are given, all the existing removable rear fittings include a ring made in one piece. Consequently, these fittings must imperatively be threaded on the cables before the ends of the latter are connected to the connector. In fact, any oversight is sanctioned by the need to completely disconnect the cables from the connector, then connect them again after inserting the connector. In addition to the loss of time induced by such an operation, the risk of error due to incorrect wiring is increased.
De même, toute opération de maintenance impliquant un remplacement du raccord ou d'une partie de celui-ci nécessite également la déconnexion, puis la remise en place de tous les câbles lorsque le remplacement a été effectué. Les inconvénients d'une telle opération sont les mêmes que lorsque les câbles ont été raccordés sur le connecteur en omettant de mettre préalablement en place le raccord arrière.Similarly, any maintenance operation involving replacement of the fitting or part of it also requires disconnection and then the replacement of all cables when the replacement has been made. The disadvantages of such an operation are the same as when the cables have been connected to the connector, failing to install the rear connector beforehand.
Exposé de l'invention L'invention a précisément pour objet un raccord arrière amovible dont la conception originale lui permet d'être monté sur un connecteur dont le câblage a déjà été effectué, ou démonté de ce connecteur, sans qu'il soit nécessaire de déconnecter les câbles.SUMMARY OF THE INVENTION The object of the invention is precisely a removable rear connector whose original design allows it to be mounted on a connector the wiring of which has already been carried out, or disassembled from this connector, without it being necessary to disconnect the cables.
Conformément à l'invention, ce résultat est obtenu au moyen d'un raccord arrière amovible pour un connecteur incluant une section arrière filetée, caractérisé par le fait qu'il comprend : - un premier sous-ensemble articulé incluant au moins deux parties de collier en arc de cercle, aptes à former un collier présentant une surface extérieure en gradins ;According to the invention, this result is obtained by means of a removable rear connector for a connector including a threaded rear section, characterized in that it comprises: - a first articulated sub-assembly including at least two collar parts in an arc, capable of forming a collar having an outer stepped surface;
- un deuxième sous-ensemble articulé en forme de bague, formé d'au moins deux parties de bague en arc de cercle et présentant une surface intérieure incluant une section avant taraudée et une section arrière en gradins, complémentaires respectivement de la section arrière filetée du connecteur et de la surface extérieure en gradins du collier.a second articulated ring-shaped subassembly, formed of at least two ring parts in an arc of a circle and having an internal surface including a tapped front section and a stepped rear section, complementary respectively to the threaded rear section of the connector and the stepped outer surface of the collar.
Un tel raccord arrière peut être monté aisément sur un connecteur équipé ou pas de son câblage, ou démonté, ce qui permet de résoudre l'ensemble des problèmes posés par les raccords de l'art antérieur. Le montage s'effectue en mettant tout d'abord en place le premier sous-ensemble articulé, de façon telle que les deux parties de collier en arc de cercle soient refermées sur le faisceau de câbles juste derrière la section arrière filetée du connecteur. On encercle ensuite simultanément cette section arrière filetée ainsi que le collier formé par le premier sous- ensemble articulé, en refermant le deuxième sous- ensemble articulé autour de ces deux éléments.Such a rear connection can be easily mounted on a connector with or without its wiring, or disassembled, which makes it possible to solve all of the problems posed by the fittings of the prior art. The assembly is carried out by first setting up the first articulated sub-assembly, in such a way that the two collar parts in an arc of a circle are closed on the cable harness just behind the threaded rear section of the connector. This threaded rear section and the collar formed by the first articulated sub-assembly are then simultaneously encircled, by closing the second articulated sub-assembly around these two elements.
Dans une forme de réalisation préférée de l'invention, le collier formé par le premier sous- ensemble articulé présente une face avant pourvue de moyens anti-rotation aptes à coopérer avec des moyens complémentaires formés sur une face arrière du connecteur. Ces moyens anti-rotation peuvent notamment être constitués par une couronne dentée formée sur la face avant du collier.In a preferred embodiment of the invention, the collar formed by the first articulated sub-assembly has a front face provided with anti-rotation means capable of cooperating with complementary means formed on a rear face of the connector. These anti-rotation means can in particular be constituted by a toothed ring formed on the front face of the collar.
Dans cette forme de réalisation de l'invention, la section arrière en gradins de la surface intérieure du deuxième sous-ensemble articulé présente une gorge annulaire qui coopère avec une nervure annulaire formée sur la surface extérieure du collier. De préférence, le deuxième sous-ensemble articulé est formé de deux parties de bague semi- circulaires articulées bout à bout et aptes à être reliées à leurs extrémités opposées, par un organe démontable telle qu'une vis orientée parallèlement aux axes desdites parties de bague. Cet agencement facilite le montage et le démontage, notamment lorsque plusieurs connecteurs sont juxtaposés sur un même panneau.In this embodiment of the invention, the stepped rear section of the inner surface of the second articulated sub-assembly has an annular groove which cooperates with an annular rib formed on the outer surface of the collar. Preferably, the second articulated sub-assembly is formed of two semicircular ring parts articulated end to end and able to be connected at their opposite ends, by a removable member such as a screw oriented parallel to the axes of said ring parts. . This arrangement facilitates assembly and disassembly, in particular when several connectors are juxtaposed on the same panel.
Par ailleurs, le premier sous-ensemble articulé comprend avantageusement deux parties de col- lier semi-circulaires, fixées rigidement aux premières extrémités de deux branches, et une demi-bride sur laquelle est articulée l'extrémité opposée d'au moins l'une des deux branches. Selon le cas, les deux bran- ches peuvent être articulées sur la demi-bride, ou une seule des branches est articulée sur la demi-bride, l'autre branche étant fixée rigidement à celle-ci.Furthermore, the first articulated sub-assembly advantageously comprises two parts of semicircular collar, rigidly fixed to the first ends of two branches, and a half-flange on which is articulated the opposite end of at least one of the two branches. Depending on the case, the two branches ches can be articulated on the half-flange, or only one of the branches is articulated on the half-flange, the other branch being rigidly fixed to the latter.
Des moyens serre-câbles tels qu'une deuxième demi-bride, sont alors montés sur la demi- bride du premier sous-ensemble articulé, par l'intermédiaire de moyens de fixation démontables.Cable clamping means such as a second half-flange are then mounted on the half-flange of the first articulated sub-assembly, by means of removable fixing means.
Afin d'éviter tout mouvement relatif entre les parties de collier en arc de cercle du premier sous-ensemble articulé, les extrémités de ces parties de collier sont de préférence de formes complémentaires, de façon à s'emboîter l'une dans l'autre.In order to avoid any relative movement between the collar parts in a circular arc of the first articulated sub-assembly, the ends of these collar parts are preferably of complementary shapes, so as to fit into each other .

Description détaillée d'une forme de réalisation préférée Sur les figures 1 et 2, la référence 10 désigne de façon générale un connecteur sur lequel peut être monté un raccord arrière amovible conforme à l'invention. Comme on l'a déjà observé, le raccord arrière amovible conforme à l'invention peut être utilisé sur différents types de connecteurs, de sorte que le connecteur 10 illustré sur les figures ne constitue qu'un exemple qui ne doit pas être considéré comme limitant les utilisations possibles du raccord selon l'invention.Detailed description of a preferred embodiment In FIGS. 1 and 2, the reference 10 generally designates a connector on which a removable rear connection conforming to the invention. As already observed, the removable rear connector according to the invention can be used on different types of connectors, so that the connector 10 illustrated in the figures is only an example which should not be considered as limiting the possible uses of the connector according to the invention.
Dans la forme de réalisation représentée, le connecteur 10 est un connecteur électrique circulaire multi-conducteurs, prévu pour être monté sur un panneau par des vis (non représentées) traversant des trous 12 formés dans une plaque 14. Le connecteur 10 est dans ce cas un connecteur fixe, comportant des alvéoles cylindriques 16 qui débouchent sur la face avant du connecteur, et dans lesquelles peuvent être reçus des contacts mâles 17.In the embodiment shown, the connector 10 is a circular multi-conductor electrical connector, intended to be mounted on a panel by screws (not shown) passing through holes 12 formed in a plate 14. The connector 10 is in this case a fixed connector, comprising cylindrical cells 16 which open onto the front face of the connector, and into which male contacts 17 can be received.
Selon un principe connu, un connecteur mobile comportant des contacts femelles peut lui aussi être directement accouplé. En arrière de la plaque 14, le connecteurAccording to a known principle, a mobile connector comprising female contacts can also be directly coupled. Behind the plate 14, the connector
10 présente un fût cylindrique 18 sur lequel est usinée une section arrière filetée 20. En arrière de cette section arrière filetée 20, le fût cylindrique 18 présente une face arrière sur laquelle est formée au moins une dent 22, de forme triangulaire. A titre d'exemple nullement limitatif, trois dents 22 peuvent être prévues sur la face arrière du fût cylindrique 18, ces dents étant régulièrement réparties autour de l'axe du connecteur 10. Un faisceau de câbles 24 est relié au connecteur 10. Plus précisément, chacun des câbles 24 est raccordé électriquement à un contact mâle 17 qui est ensuite introduit dans l'une des cavités cylindriques 16 de ce connecteur 10, de l'arrière vers l'avant, et débouche sur la face avant du connecteur.10 has a cylindrical barrel 18 on which a threaded rear section is machined 20. Behind this threaded rear section 20, the cylindrical barrel 18 has a rear face on which is formed at least one tooth 22, of triangular shape. By way of non-limiting example, three teeth 22 can be provided on the rear face of the cylindrical barrel 18, these teeth being regularly distributed around the axis of the connector 10. A bundle of cables 24 is connected to the connector 10. More precisely each of the cables 24 is electrically connected to a male contact 17 which is then introduced into one of the cavities cylindrical 16 of this connector 10, from rear to front, and opens onto the front face of the connector.
On a également représenté sur les figures 1 et 2 les principaux éléments constitutifs d'un raccord arrière amovible conforme à l'invention, apte à être monté sur le connecteur 10, ou démonté de celui-ci, sans qu'aucun des câbles 24 du faisceau n'ait à être déverrouillé du connecteur 10.Also shown in Figures 1 and 2 the main components of a removable rear connector according to the invention, adapted to be mounted on the connector 10, or removed therefrom, without any of the cables 24 of the harness does not have to be unlocked from connector 10.
Le raccord arrière amovible conforme à l'invention comprend un premier sous-ensemble articulé, désigné de façon générale par la référence 26 sur les figures, et un deuxième sous-ensemble articulé, en forme de bague, désigné de façon générale par la référence 28. Une description détaillée de chacun de ces sous-ensembles va à présent être faite.The removable rear connector according to the invention comprises a first articulated sub-assembly, generally designated by the reference 26 in the figures, and a second articulated sub-assembly, in the form of a ring, generally designated by the reference 28 A detailed description of each of these subsets will now be made.
Le premier sous-ensemble articulé 26 est formé de trois pièces 30a, 30b et 32, chacune des pièces 30a et 30b étant articulée sur la pièce 32 par un axe 34a, 34b. De façon plus précise, chacune des piècesThe first articulated sub-assembly 26 is formed of three parts 30a, 30b and 32, each of the parts 30a and 30b being articulated on the part 32 by an axis 34a, 34b. More precisely, each of the pieces
30a et 30b comprend une partie de collier semi- circulaire 36a, 36b et une branche 38a, 38b dont une première extrémité est fixée rigidement à la partie de collier semi-circulaire qui lui correspond. Comme l'illustrent les figures, les branches 38a et 38b et les parties de collier semi-circulaires 36a et 36b peuvent notamment être réalisées d'un seul tenant. Dans la forme de réalisation représentée, les branches 38a et 38b sont sensiblement droites, raccordées au milieu des parties de collier semi-circulaires 36a et 36b, et orientées parallèlement à l'axe de la partie de collier correspondante . La troisième pièce 32 du premier sous- ensemble articulé 26 est une demi-bride aux extrémités de laquelle sont articulées les pièces 30a et 30b. Plus précisément, les pièces 30a et 30b sont articulées sur la demi-bride 32 par les extrémités des branches 38a et 38b opposées à celles qui supportent les parties de collier semi-circulaires 36a et 36b. Les axes 34a et 34b sont orientés parallèlement l'un à l'autre, selon des directions orthogonales aux axes des parties de collier semi-circulaires 36a et 36b.30a and 30b comprises a semicircular collar part 36a, 36b and a branch 38a, 38b, a first end of which is rigidly fixed to the semicircular collar part which corresponds to it. As illustrated in the figures, the branches 38a and 38b and the semi-circular collar parts 36a and 36b can in particular be made in one piece. In the embodiment shown, the branches 38a and 38b are substantially straight, connected in the middle of the semicircular collar parts 36a and 36b, and oriented parallel to the axis of the corresponding collar part. The third part 32 of the first articulated sub-assembly 26 is a half-flange at the ends of which the parts 30a and 30b are articulated. More specifically, the parts 30a and 30b are articulated on the half-flange 32 by the ends of the branches 38a and 38b opposite those which support the parts of the semicircular collar 36a and 36b. The axes 34a and 34b are oriented parallel to each other, in directions orthogonal to the axes of the semi-circular collar portions 36a and 36b.
L'agencement qui vient d'être décrit permet au premier sous-ensemble articulé 26 de pouvoir occuper à volonté soit une position ouverte, illustrée sur la figure 1, dans laquelle les deux pièces 30a et 30b sont pivotées en écartement l'une de l'autre autour des axes 34a et 34b, soit une position fermée, illustrée sur la figure 2, dans laquelle les pièces 30a et 30b sont en appui l'une contre l'autre par les extrémités des parties de collier semi-circulaires 36a et 36b. Dans la position ouverte du premier sous- ensemble articulé 26, celui-ci peut être mis en place ou, au contraire, séparé du connecteur 10 équipé de son faisceau de câbles 24, comme le montre la figure 1. Au contraire, dans la position fermée du premier sous- ensemble articulé 26, les deux parties de collier semi- circulaires 36a et 36b forment un collier qui encercle complètement le faisceau de câbles 24, derrière la face arrière du fût cylindrique 18 du connecteur 10.The arrangement which has just been described allows the first articulated sub-assembly 26 to be able to occupy at will either an open position, illustrated in FIG. 1, in which the two parts 30a and 30b are pivoted in spacing one of the other around the axes 34a and 34b, that is to say a closed position, illustrated in FIG. 2, in which the parts 30a and 30b are pressed one against the other by the ends of the parts of semicircular collar 36a and 36b . In the open position of the first articulated sub-assembly 26, this can be put in place or, on the contrary, separated from the connector 10 equipped with its cable harness 24, as shown in FIG. 1. On the contrary, in the position closed from the first articulated sub-assembly 26, the two semi-circular collar parts 36a and 36b form a collar which completely encircles the bundle of cables 24, behind the rear face of the cylindrical barrel 18 of the connector 10.
Afin d'éviter des déplacements relatifs entre les extrémités des deux parties de collier semi- circulaires 36a et 36b, lorsque le premier sous- ensemble articulé 26 est dans sa position fermée, les extrémités en vis-à-vis de ces parties de collier sont de formes complémentaires, de façon à s'emboîter l'une dans l'autre. Ainsi, les extrémités de la partie 36a comportent respectivement une saillie 48a et un creux 50a, alors que les extrémités correspondantes de la partie 36b comportent un creux (non visible sur les figures) et une saillie 48b.In order to avoid relative displacements between the ends of the two semi-circular collar parts 36a and 36b, when the first articulated sub-assembly 26 is in its closed position, the opposite ends of these collar parts are complementary shapes, so as to fit one into the other. Thus, the ends of the part 36a respectively comprise a projection 48a and a recess 50a, while the corresponding ends of the part 36b comprise a recess (not visible in the figures) and a projection 48b.
Lorsque le premier sous-ensemble articulé 26 occupe sa position fermée illustrée sur la figure 2, le collier alors constitué par les deux parties de collier 36a et 36b présente, sur sa face avant, des moyens anti-rotation constitués par une couronne dentée 52. Plus précisément, cette couronne dentée 52 est formée de dents triangulaires complémentaires des dents 22 qui font saillie sur la face arrière du fût cylindrique 18 du connecteur 10. Ces dents triangulaires sont usinées sur la face avant de chacune des parties de collier semi-circulaires 36a et 36b.When the first articulated sub-assembly 26 occupies its closed position illustrated in FIG. 2, the collar then formed by the two collar parts 36a and 36b has, on its front face, anti-rotation means constituted by a toothed crown 52. More specifically, this toothed ring 52 is formed of triangular teeth complementary to the teeth 22 which protrude from the rear face of the cylindrical barrel 18 of the connector 10. These triangular teeth are machined on the front face of each of the parts of the semi-circular collar 36a and 36b.
Les moyens anti-rotation formés par la couronne dentée 52 coopèrent ainsi avec les moyens complémentaires formés par les dents 22, pour immobiliser en rotation le premier sous-ensemble articulé 26 par rapport au connecteur 10, lorsque ce premier sous-ensemble occupe sa position fermée et lorsqu'il est maintenu appliqué contre la face arrière du fût 18 par le deuxième sous-ensemble articulé 28, comme l'illustre la figure 2.The anti-rotation means formed by the toothed ring 52 thus cooperate with the complementary means formed by the teeth 22, to immobilize in rotation the first articulated sub-assembly 26 relative to the connector 10, when this first sub-assembly occupies its closed position and when it is kept applied against the rear face of the barrel 18 by the second articulated sub-assembly 28, as illustrated in FIG. 2.
Lorsque le premier sous-ensemble articulé 26 occupe la position fermée illustrée sur la figure 2, le collier alors formé par les deux parties de collier semi-circulaires 36a et 36b présente alors, sur sa surface extérieure, une nervure annulaire 54. Cette nervure annulaire 54 donne à la surface extérieure du collier une forme en gradins dont on verra ultérieurement qu'elle permet de lier en translation le deuxième sous-ensemble articulé 28 au premier sous- ensemble articulé 26, tout en autorisant leur rotation relative, lorsque ces deux sous-ensembles sont en position fermée. La nervure annulaire 54 est formée de deux parties, usinées respectivement sur chacune des deux parties de collier semi-circulaires 36a et 36b.When the first articulated sub-assembly 26 occupies the closed position illustrated in FIG. 2, the collar then formed by the two semi-circular collar parts 36a and 36b then has, on its outer surface, an annular rib 54. This annular rib 54 gives the outer surface of the necklace a stepped shape which we will see later that it makes it possible to link in translation the second articulated sub-assembly 28 to the first articulated sub-assembly 26, while allowing their relative rotation, when these two sub-assemblies are in the closed position. The annular rib 54 is formed of two parts, machined respectively on each of the two parts of semicircular collar 36a and 36b.
Le deuxième sous-ensemble articulé 28, en forme de bague, va à présent être décrit en détail en se référant aux figures.The second articulated sub-assembly 28, in the form of a ring, will now be described in detail with reference to the figures.
Dans la forme de réalisation représentée, ce deuxième sous-ensemble articulé 28 est formé de deux parties de bague semi-circulaires 56a et 56b, articulées bout à bout par un axe 58, orienté parallèlement aux axes de chacune de ces deux parties. Cet agencement permet au deuxième sous-ensemble articulé 28 d'occuper à volonté soit une position ouverte, représentée sur les figures, permettant sa mise en place et son enlèvement, soit une position fermée (non représentée) , dans laquelle le deuxième sous-ensemble 28 forme une bague.In the embodiment shown, this second articulated sub-assembly 28 is formed of two semi-circular ring parts 56a and 56b, articulated end to end by an axis 58, oriented parallel to the axes of each of these two parts. This arrangement allows the second articulated sub-assembly 28 to occupy at will either an open position, shown in the figures, allowing its installation and removal, or a closed position (not shown), in which the second sub-assembly 28 forms a ring.
Lorsqu'il est en position fermée, le deuxième sous-ensemble articulé 28 entoure en les chevauchant l'arrière du connecteur 10 et l'avant du premier sous-ensemble 26. De façon plus précise, le deuxième sous-ensemble articulé 28 entoure alors à la fois la section arrière filetée 20 formée sur le fût cylindrique 18 du connecteur 10 et la surface extérieure en gradins 54 du collier formé par les deux parties de collier semi-circulaires 36a et 36b du premier sous-ensemble articulé 26. Afin de permettre au deuxième sous-ensemble articulé 28, en forme de bague, de coopérer respectivement avec la section arrière filetée 20 et avec la surface extérieure en gradins 54, ce deuxième sous-ensemble présente, sur sa surface intérieure, une section avant taraudée 60 et une section arrière en gradins matérialisée par une gorge annulaire 62, lorsqu'il est en position fermée. La section avant taraudée 60 et la gorge annulaire 62 sont usinées respectivement sur chacune des deux parties de bague semi-circulaires 56a et 56b, comme l'illustre notamment la figure 1. De façon plus précise, la section avant taraudée 60 est complémentaire de la section arrière filetée 20 du connecteur et la section arrière en gradins 62 est complémentaire de la surface extérieure en gradins 54 du collier formé par le premier sous- ensemble articulé 26, lorsqu'il est en position fermée. Grâce à l'agencement qui vient d'être décrit, lorsque le deuxième sous-ensemble articulé 28 en forme de bague est fermé et encercle à la fois l'arrière du connecteur 10 et l'avant du premier sous- ensemble articulé 26, la section avant taraudée 60 et la section arrière filetée 20 sont en prise et la gorge annulaire 62 est emboîtée sur la nervure annulaire 54. II est alors possible de faire tourner le deuxième sous-ensemble articulé 28 autour de l'axe du connecteur, afin de le visser ou de le dévisser de celui-ci, sans pour autant entraîner en rotation le premier sous-ensemble articulé 26. En effet, la coopération entre la gorge 62 et la nervure 54 autorise une rotation relative avec les deux sous-ensembles. En revanche, cette coopération relie les deux sous- ensembles en translation parallèlement à l'axe du connecteur. Par conséquent, lorsque le deuxième sous- ensemble articulé 28, en position fermée, est vissé sur la section arrière filetée 20, la couronne dentée 52 est plaquée contre les dents 22 et le premier sous- ensemble articulé 26 est solidarisé du connecteur 10.When in the closed position, the second articulated sub-assembly 28 surrounds by overlapping the rear of the connector 10 and the front of the first sub-assembly 26. More precisely, the second articulated sub-assembly 28 then surrounds both the threaded rear section 20 formed on the cylindrical barrel 18 of the connector 10 and the stepped exterior surface 54 of the collar formed by the two semi-circular collar parts 36a and 36b of the first articulated sub-assembly 26. In order to allow the second articulated sub-assembly 28, in the form of a ring, to cooperate respectively with the threaded rear section 20 and with the stepped outer surface 54, this second sub-assembly has, on its inner surface, a tapped front section 60 and a rear stepped section materialized by an annular groove 62, when it is in the closed position. The tapped front section 60 and the annular groove 62 are machined respectively on each of the two semi-circular ring parts 56a and 56b, as illustrated in particular in FIG. 1. More specifically, the tapped front section 60 is complementary to the rear threaded section 20 of the connector and the rear stepped section 62 is complementary to the external stepped surface 54 of the collar formed by the first articulated sub-assembly 26, when it is in the closed position. Thanks to the arrangement which has just been described, when the second articulated sub-assembly 28 in the form of a ring is closed and encircles both the rear of the connector 10 and the front of the first articulated sub-assembly 26, the tapped front section 60 and threaded rear section 20 are engaged and the annular groove 62 is fitted onto the annular rib 54. It is then possible to rotate the second articulated sub-assembly 28 around the axis of the connector, in order to screw it or unscrew it, without rotating the first articulated sub-assembly 26. In fact, the cooperation between the groove 62 and the rib 54 allows relative rotation with the two sub-assemblies. However, this cooperation connects the two subsets in translation parallel to the axis of the connector. Consequently, when the second articulated sub-assembly 28, in the closed position, is screwed onto the threaded rear section 20, the ring gear 52 is pressed against the teeth 22 and the first articulated sub-assembly 26 is secured to the connector 10.
Pour faciliter le vissage et le dévissage du deuxième sous-ensemble articulé 28, en position fermée, sa surface extérieure est avantageusement moletée ou munie de méplats. Comme on l'a représenté sur les figures 1 et 2, les extrémités des deux parties de bague serai- circulaires 56a et 56b opposées à l'axe d'articulation 58 sont prévues pour être reliées l'une à l'autre par un organe démontable tel qu'une vis 64. Cette vis 64 est orientée, de préférence, parallèlement aux axes des parties de bague semi-circulaires 56a et 56b, c'est-à- dire parallèlement à l'axe du connecteur lorsque le deuxième sous-ensemble articulé 28 est en position fermée et placé autour de l'extrémité arrière du connecteur et de l'extrémité avant du premier sous- ensemble articulé 26. Cette caractéristique permet d'effectuer le montage et le démontage du deuxième sous-ensemble articulé 28 même lorsque le connecteur 10 est implanté dans une zone fortement encombrée, et notamment à côté d'autres connecteurs.To facilitate the screwing and unscrewing of the second articulated sub-assembly 28, in the closed position, its outer surface is advantageously knurled or provided with flats. As shown in FIGS. 1 and 2, the ends of the two seri-circular ring parts 56a and 56b opposite the hinge pin 58 are designed to be connected to one another by a member removable such as a screw 64. This screw 64 is preferably oriented parallel to the axes of the semicircular ring parts 56a and 56b, that is to say parallel to the axis of the connector when the second sub- articulated assembly 28 is in the closed position and placed around the rear end of the connector and the front end of the first articulated sub-assembly 26. This characteristic makes it possible to assemble and disassemble the second articulated sub-assembly 28 itself when the connector 10 is located in a highly congested area, and in particular next to other connectors.
Dans la forme de réalisation représentée notamment sur la figure 2, la demi-bride 32 supporte de façon amovible des moyens serre-câbles constitués dans ce cas par une deuxième demi-bride 66. Cette deuxième demi-bride 66 est prévue pour être montée sur la demi- bride 32 par des moyens de fixation démontables constitués dans ce cas par deux vis 68. Les vis 68 traversent des trous usinés aux extrémités de la deuxième demi-bride 66 et viennent se visser dans des taraudages formés dans les axes 34a et 34b par lesquels les pièces 30a et 30b sont articulées sur la demi-bride 32. Chacun des sous-ensembles articulés 26 etIn the embodiment shown in particular in Figure 2, the half-flange 32 removably supports cable clamping means formed in this case by a second half-flange 66. This second half-flange 66 is provided to be mounted on the half flange 32 by removable fixing means constituted in this case by two screws 68. The screws 68 pass through holes machined at the ends of the second half-flange 66 and are screwed into threads formed in the axes 34a and 34b by which the parts 30a and 30b are articulated on the half-flange 32. Each of the articulated sub-assemblies 26 and
28 est assemblé en usine. A cet effet, les axes 34a et 34b ainsi que l'axe 58 sont avantageusement constitués par des rivets tubulaires.28 is factory assembled. To this end, the axes 34a and 34b as well as the axis 58 are advantageously constituted by tubular rivets.
Pour mettre en place le raccord arrière amovible conforme à l'invention, on monte d'abord le premier sous-ensemble articulé 26. A cet effet, on place ce premier sous-ensemble dans la position ouverte illustrée sur la figure 1, de façon telle que la demi- bride 32 soit en appui contre le faisceau de câbles 24 et que les deux parties de collier en arc de cercle 36a et 36b soient situées derrière le fût cylindrique 18 du connecteur 10. Le premier sous-ensemble articulé 26 est alors amené dans sa position fermée illustrée sur la figure 2, de telle sorte que le collier formé par les deux parties 36a et 36b entoure le faisceau de câbles 24, immédiatement en arrière du fût cylindrique 18.To set up the removable rear connector according to the invention, the first articulated sub-assembly 26 is first mounted. For this purpose, this first sub-assembly is placed in the open position illustrated in FIG. 1, so such that the half-flange 32 is in abutment against the cable harness 24 and that the two collar parts in a circular arc 36a and 36b are located behind the cylindrical barrel 18 of the connector 10. The first articulated sub-assembly 26 is then brought into its closed position illustrated in FIG. 2, so that the collar formed by the two parts 36a and 36b surrounds the bundle of cables 24, immediately behind the cylindrical barrel 18.
On met alors en place le deuxième sous- ensemble articulé 28 en le présentant en position ouverte comme l'illustre la figure 1 et en engageant la gorge 62 et la section avant taraudée 60 de l'une des deux parties de bague 56a et 56b respectivement sur la nervure annulaire 54 et dans la section arrière filetée 20, comme le montre la figure 2.The second articulated sub-assembly 28 is then put in place by presenting it in the open position as illustrated in FIG. 1 and by engaging the groove 62 and the tapped front section 60 of one of the two ring parts 56a and 56b respectively. on the annular rib 54 and in the threaded rear section 20, as shown in FIG. 2.
Le deuxième sous-ensemble articulé 28 est ensuite fermé en rabattant la deuxième partie de bague semi-circulaire, de façon à encercler complètement la section arrière filetée 20 du connecteur et la nervure annulaire 54 du premier sous-ensemble articulé 26. Le deuxième sous-ensemble articulé 28 est verrouillé dans cette position fermée au moyen de la vis 64.The second articulated sub-assembly 28 is then closed by folding down the second part of the semi-circular ring, so as to completely encircle the threaded rear section 20 of the connector and the annular rib 54 of the first articulated sub-assembly 26. The second articulated sub-assembly 28 is locked in this closed position by means of the screw 64.
Pour terminer le montage du raccord, la bague formée par le deuxième sous-ensemble articulé 28 est vissée sur la section arrière filetée 20 du connecteur 10 jusqu'à ce que la couronne dentée 52 soit totalement plaquée contre les dents 22.To complete the fitting of the fitting, the ring formed by the second articulated sub-assembly 28 is screwed onto the threaded rear section 20 of the connector 10 until the toothed crown 52 is completely pressed against the teeth 22.
Lorsque le raccord arrière amovible est utilisé pour maintenir le faisceau de câbles 24 comme dans l'exemple décrit, la deuxième demi-bride 66 est fixée sur la première demi-bride 32 par les vis 68. Le faisceau de câbles 24 est alors serré entre les deux demi-brides 32 et 66.When the removable rear connector is used to hold the cable harness 24 as in the example described, the second half-flange 66 is fixed to the first half-flange 32 by the screws 68. The cable bundle 24 is then clamped between the two half-flanges 32 and 66.
Si une intervention de maintenance nécessite le remplacement de tout ou partie du raccord arrière amovible, son démontage peut être fait en procédant aux opérations décrites précédemment, dans l'ordre inverse, là encore sans déconnexion des câbles 24. Comme on l'a déjà observé à différentes reprises, l'invention n'est pas limitée à la forme de réalisation qui vient d'être décrite en référence aux figures 1 et 2.If a maintenance intervention requires the replacement of all or part of the removable rear connection, its disassembly can be done by carrying out the operations described above, in reverse order, again without disconnecting the cables 24. As already observed on various occasions, the invention is not limited to the embodiment which has just been described with reference to FIGS. 1 and 2.
Ainsi, la fonction du raccord arrière amovible selon l'invention peut être une fonction différente de celle qui a été décrite, telle qu'une fonction d'étanchéité. Les organes assurant l'étanchéité sont alors supportés par le premier sous- ensemble articulé, de la même manière que les organes destinés à maintenir le faisceau de câbles dans l'exemple décrit. Par ailleurs, dans le cas où le raccord arrière amovible sert à maintenir le faisceau de câbles, cette fonction peut être remplie par des moyens présentant des formes différentes de ceux qui ont été décrits. Ainsi, le maintien du faisceau de câbles peut être assuré par des frettes de câblage, des manchons thermorétractables, etc.. De plus, l'orientation entre ces moyens de maintien du faisceau de câbles et l'axe du connecteur peut être différent de l'orientation coaxiale décrite. Ainsi, le faisceau de câbles peut être orienté par exemple à 45° ou à 90° par rapport à l'axe du connecteur, en donnant aux branches 38a et 38b des formes coudées.Thus, the function of the removable rear connector according to the invention can be a function different from that which has been described, such as a sealing function. The sealing members are then supported by the first articulated sub-assembly, in the same way as the members intended to maintain the cable bundle in the example described. Furthermore, in the case where the removable rear connector is used to hold the cable harness, this function can be fulfilled by means having shapes different from those which have been described. Thus, the maintenance of the cable bundle can be ensured by wiring hoops, heat-shrink sleeves, etc. In addition, the orientation between these means for maintaining the cable bundle and the axis of the connector can be different from the coaxial orientation described. Thus, the cable bundle can be oriented for example at 45 ° or 90 ° relative to the axis of the connector, giving the branches 38a and 38b bent shapes.
Enfin, les différents moyens qui ont été décrits notamment pour assurer l'immobilisation en rotation du premier sous-ensemble articulé par rapport au connecteur et pour assurer la liaison tournante entre les deux sous-ensembles articulés peuvent être remplacés par tout moyen techniquement équivalent. De même, les formes données aux deux sous-ensembles, et notamment le nombre de parties ou de pièces en arc de cercle les constituant peuvent être modifiées, sans sortir du cadre de l'invention. Ainsi, au lieu d'être toutes deux articulées sur la demi-bride 32, une des deux branches 38a, 38b peut être fixée rigidement à celle-ci, ce qui permet de diminuer le coût de fabrication en supprimant une articulation. Finally, the various means which have been described in particular for ensuring the immobilization in rotation of the first articulated sub-assembly with respect to the connector and for ensuring the rotary connection between the two articulated sub-assemblies can be replaced by any technically equivalent means. Similarly, the shapes given to the two sub-assemblies, and in particular the number of parts or parts in an arc forming them can be modified, without departing from the scope of the invention. Thus, instead of being both articulated on the half-flange 32, one of the two branches 38a, 38b can be rigidly fixed thereto, which makes it possible to reduce the manufacturing cost by eliminating a joint.
