L'une au moins parmi la portion de sertissage du contact central du connecteur et une portion de sertissage du corps du connecteur comporte avantageusement une section transversale sensiblement en U ou en V.The invention advantageously allows the crimping of the coaxial cable on the bent connector in a relatively small number of operations. At least one of the crimping portion of the central contact of the connector and a crimping portion of the connector body advantageously has a cross section substantially U or V.

Contrairement à ce qui est divulgué dans le brevet EP 1 653 574 , le connecteur coaxial peut être dépourvu de dégagement ménagé de part et d'autre de la portion d'appui de l'élément isolant, et s'étendant au moins partiellement sous la portion de sertissage du contact central. L'absence d'un tel dégagement peut permettre, lors du sertissage, le passage d'un outil plus large et, par conséquent, plus résistant.Unlike what is disclosed in the patent EP 1 653 574 , the coaxial connector may be devoid of clearance formed on either side of the bearing portion of the insulating member, and extending at least partially under the crimping portion of the central contact. The absence of such a clearance can allow, during crimping, the passage of a wider tool and, therefore, more resistant.

L'élément isolant du connecteur est avantageusement configuré de façon à ce que le contact central du connecteur soit fixé à ce dernier par une liaison à baïonnette, ce qui peut permettre de monter le contact central de façon relativement simple et sûre dans l'élément isolant du connecteur coaxial.The insulating element of the connector is advantageously configured so that the central contact of the connector is fixed thereto by a bayonet connection, which can make it possible to mount the central contact in a relatively simple and safe manner in the insulating element. coaxial connector.

Le premier axe et le deuxième axe du manchon ne sont pas parallèles, étant avantageusement perpendiculaires, formant un coude.The first axis and the second axis of the sleeve are not parallel, being preferably perpendicular, forming a bend.

Le manchon est avantageusement réalisé d'une seule pièce, par exemple en métal.The sleeve is advantageously made in one piece, for example metal.

Le manchon peut être différent du corps du connecteur, le manchon et ledit corps étant par exemple des pièces distinctes.The sleeve may be different from the body of the connector, the sleeve and said body being for example separate parts.

La première portion du manchon comporte avantageusement sur sa surface latérale extérieure au moins une gorge s'étendant sur au moins une partie du pourtour de ladite première portion du manchon, notamment sur tout son pourtour.The first portion of the sleeve advantageously comprises on its outer lateral surface at least one groove extending over at least a portion of the periphery of said first portion of the sleeve, in particular all around.

La première portion du manchon comporte avantageusement sur sa surface intérieure au moins une rainure s'étendant parallèlement au premier axe du manchon et destinée à coopérer avec des pattes ménagées sur la surface extérieure du corps du connecteur coaxial, de façon à permettre la fixation amovible du connecteur coaxial à l'intérieur de la première portion du manchon.The first portion of the sleeve advantageously has on its inner surface at least one groove extending parallel to the first axis of the sleeve and intended to cooperate with tabs formed on the outer surface of the body of the coaxial connector, so as to allow the removable attachment of the coaxial connector inside the first portion of the sleeve.

Le boîtier s'étend selon un axe longitudinal et comporte avantageusement au moins une patte élastique configurée pour coopérer avec la gorge de la première portion du manchon pour maintenir le boîtier sur le manchon par encliquetage. La patte élastique peut également permettre d'assurer une reprise des efforts mécaniques entre le boîtier et le manchon lorsqu'ils sont assemblés.The housing extends along a longitudinal axis and advantageously comprises at least one elastic tab configured to cooperate with the groove of the first portion of the sleeve to hold the housing on the sleeve by snapping. The elastic tab may also allow to ensure a recovery of the mechanical forces between the housing and the sleeve when assembled.

Le boîtier peut être droit, son axe longitudinal étant alors rectiligne. Le boîtier peut n'être pas coudé.The housing can be straight, its longitudinal axis then being rectilinear. The housing may not be bent.

Le fond de la gorge comporte avantageusement une pluralité d'encoches s'étendant parallèlement au premier axe du manchon et qui peuvent constituer des moyens d'indexation du boîtier par rapport à la première portion du manchon. Ces encoches sont avantageusement uniformément réparties sur le pourtour de la première portion du manchon.The bottom of the groove advantageously comprises a plurality of notches extending parallel to the first axis of the sleeve and which can constitute indexing means of the housing relative to the first portion of the sleeve. These notches are advantageously uniformly distributed around the periphery of the first portion of the sleeve.

La gorge est avantageusement latéralement bordée par une collerette comportant au moins deux portions séparées par un évidement. Cette collerette peut permettre de contribuer à la reprise des efforts mécaniques entre le manchon et le boîtier lorsqu'ils sont assemblés.The groove is advantageously laterally bordered by a collar comprising at least two portions separated by a recess. This collar can allow to contribute to the recovery of the mechanical forces between the sleeve and the housing when they are assembled.

Le boîtier comporte avantageusement sur sa surface latérale intérieure au moins un pion configuré pour coulisser dans l'évidement de la collerette et/ou pour être maintenu par friction dans une encoche de la gorge. Le ou les pions peuvent permettre une reprise des efforts mécaniques entre le boîtier et le manchon lorsqu'ils sont assemblés.The housing advantageously has on its inner side surface at least one pin configured to slide in the recess of the flange and / or to be frictionally held in a notch of the groove. The one or more pins can allow a recovery of the mechanical forces between the housing and the sleeve when they are assembled.

Les pions sont avantageusement disposés au niveau ou à proximité d'une extrémité longitudinale du boîtier.The pins are advantageously arranged at or near a longitudinal end of the housing.

La collerette du manchon comporte par exemple trois évidements et la surface intérieure du boîtier trois pions. La coopération entre les pions et les évidements peut permettre d'amener la ou les pattes élastiques du boîtier dans une position d'encliquetage dans la gorge de la première portion du manchon et, une fois cette position d'encliquetage atteinte, le boîtier peut être déplacé en rotation autour de la première portion du manchon dans des positions angulaires prédéfinies correspondant à la position des encoches de la gorge. Le boîtier peut être maintenu dans les positions angulaires prédéfinies par coopération entre les pions et les encoches.The collar of the sleeve comprises for example three recesses and the inner surface of the housing three pins. The cooperation between the pins and the recesses can make it possible to bring the elastic tab or tabs of the casing into a latching position in the groove of the first portion of the sleeve and, once this latching position is reached, the casing can be rotated around the first portion of the sleeve in predefined angular positions corresponding to the position of the notches in the groove. The housing can be maintained in the predefined angular positions by cooperation between the pins and the notches.

Le boîtier permet avantageusement d'assurer une fonction de rétention grâce à la ou les pattes élastiques et une fonction d'indexation grâce aux pions, sans ajout d'une pièce supplémentaire de type rondelle élastique ou pièce/patte plastique comme utilisé couramment dans les solutions connues.The housing advantageously provides a retention function with the elastic tab or legs and an indexing function with the pions, without adding an additional piece of elastic washer type or piece / plastic tab as commonly used in solutions known.

Le boîtier comporte avantageusement une zone pour l'accouplement à un boîtier complémentaire d'un autre ensemble de connexion, cette zone étant de préférence située sur la face supérieure du boîtier. Cette zone comporte avantageusement un arceau s'étendant transversalement, notamment perpendiculairement, par rapport à l'axe longitudinal du boîtier et une patte montée pivotante sur le boîtier autour d'un axe perpendiculaire à l'axe longitudinal du boîtier, ladite patte étant avantageusement recouverte au moins en partie par l'arceau. L'arceau peut comporter au moins une découpe ménagée en regard d'une extrémité longitudinale de ladite patte, ce qui peut permettre d'assurer une amplitude satisfaisante au mouvement de pivotement de la patte, sans qu'il soit nécessaire d'augmenter la hauteur de l'arceau pour ce faire. L'invention peut ainsi permettre de réduire l'encombrement lié au boîtier.The housing advantageously comprises a zone for coupling to a housing complementary to another connection assembly, this zone being preferably located on the upper face of the housing. This zone advantageously comprises a hoop extending transversely, in particular perpendicularly, with respect to the longitudinal axis of the housing and a lug pivotally mounted on the housing about an axis perpendicular to the longitudinal axis of the housing, said lug being advantageously covered at least partly by the arch. The arch may comprise at least one cutout facing a longitudinal end of said tab, which can ensure a satisfactory amplitude to the pivoting movement of the leg, without the need to increase the height of the hoop to do this. The invention can thus make it possible to reduce the bulk associated with the housing.

En l'absence d'accouplement du boîtier à un boîtier d'un ensemble de connexion complémentaire, l'axe longitudinal de la patte de la zone pour l'accouplement est avantageusement parallèle à l'axe longitudinal du boîtier.In the absence of coupling of the housing to a housing of a complementary connection assembly, the longitudinal axis of the tab of the zone for the coupling is advantageously parallel to the longitudinal axis of the housing.

L'arceau et la patte peuvent être réalisés d'une seule pièce avec le reste du boîtier ou, en variante, être rapportés sur ce dernier.The hoop and the tab can be made in one piece with the rest of the housing or, alternatively, be reported on the latter.

L'arceau ne s'étend avantageusement que sur une portion de la longueur du boîtier, par exemple sur une portion de la longueur du boîtier depuis une extrémité longitudinale de ce dernier, ladite extrémité longitudinale venant au contact du boîtier d'un ensemble de connexion complémentaire lors d'un accouplement à ce dernier.The hoop advantageously extends only over a portion of the length of the housing, for example over a portion of the length of the housing from a longitudinal end of the latter, said longitudinal end coming into contact with the housing of a connection assembly complementary during a coupling to the latter.

L'ensemble comporte avantageusement un capot de verrouillage configuré pour fermer le logement ménagé dans la deuxième portion du manchon.The assembly advantageously comprises a locking cap configured to close the housing formed in the second portion of the sleeve.

Le capot de verrouillage est avantageusement métallique. La configuration du manchon et du capot permet de limiter les fuites hautes fréquences et renforcer le maintien mécanique du connecteur dans le manchon. Le manchon, qui est par exemple métallique, vient avantageusement entourer le corps du connecteur coaxial, ce qui peut réduire les risques de dégradation de ce dernier, par exemple par cambrage du corps, tout en facilitant l'accouplement avec un ensemble de connexion complémentaire, du fait que le manchon assure une fonction de guidage.The locking cap is advantageously metallic. The configuration of the sleeve and the cover makes it possible to limit high frequency leakage and reinforce the mechanical retention of the connector in the sleeve. The sleeve, which is for example metallic, advantageously surrounds the body of the coaxial connector, which can reduce the risk of degradation of the latter, for example by bending the body, while facilitating coupling with a complementary connection assembly, because the sleeve provides a guiding function.

Le capot de verrouillage est avantageusement monté pivotant sur le manchon.The locking cap is advantageously pivotally mounted on the sleeve.

Le capot de verrouillage comporte avantageusement une patte élastique configurée pour appuyer sur le corps du connecteur lorsque ce dernier est reçu dans le logement de la deuxième portion du manchon et s'opposer à la fermeture dudit capot.The locking cap advantageously comprises an elastic tab configured to press on the body of the connector when the latter is received in the housing of the second portion of the sleeve and oppose the closure of said cover.

L'appui de la patte élastique du capot de verrouillage sur le corps de connecteur peut établir une continuité électrique avec le connecteur coaxial, assurant une reprise de masse. Par ailleurs, la patte élastique s'opposant à la fermeture du capot, le capot est avantageusement maintenu ouvert tant qu'une force suffisante n'a pas été exercée sur ce dernier pour le fermer.The support of the elastic tab of the locking cap on the connector body can establish an electrical continuity with the coaxial connector, ensuring a resumption of mass. Furthermore, the elastic tab opposing the closing of the cover, the cover is advantageously kept open until sufficient force has been exerted on the latter to close it.

Le manchon et le capot peuvent être deux pièces distinctes, de préférence métalliques, reliées par une charnière pivotante ou, en variante, être réalisés d'une seule pièce, notamment en plastique métallisé comprenant une charnière élastique.The sleeve and the cover may be two separate parts, preferably metal, connected by a pivot hinge or, alternatively, be made in one piece, in particular metallized plastic comprising an elastic hinge.

  • close a locking cap mounted on the sleeve, so as to hold the electrical connector in the sleeve.

Le boîtier évidé peut être monté par encliquetage sur une portion du manchon coudé, ce boîtier pouvant être déplacé en rotation autour du manchon.The recessed housing can be snap-fitted onto a portion of the elbow sleeve, which housing can be rotated around the sleeve.

Le sertissage du conducteur central du câble coaxial avec le contact central du connecteur coaxial peut être accompagné du sertissage simultané de l'une au moins d'une tresse de blindage et d'une gaine isolante interne et/ou d'une gaine isolante externe avec des portions de sertissage correspondantes du corps du connecteur coaxial.The crimping of the central conductor of the coaxial cable with the central contact of the coaxial connector may be accompanied by simultaneous crimping of at least one shielding braid and an inner insulating sheath and / or an outer insulating sheath with corresponding crimping portions of the body of the coaxial connector.

Le procédé selon l'invention peut être particulièrement simple et rapide à mettre en ouvre, permettant ainsi de simplifier les opérations d'assemblage d'un ensemble de connexion comportant un connecteur coudé coaxial ainsi que les opérations d'accouplement d'un tel ensemble à un ensemble complémentaire.The method according to the invention can be particularly simple and quick to implement, thereby simplifying assembly operations of a connection assembly comprising a coaxial angled connector and the coupling operations of such a set to a complementary set.

On a représenté à la figure 1, un ensemble de connexion désigné globalement par 1, selon un exemple de mise en oeuvre de l'invention.We have shown figure 1 , a connection assembly generally designated 1, according to an exemplary implementation of the invention.

Cet ensemble 1 comporte dans l'exemple décrit, un connecteur coaxial coudé désigné globalement par 2 et monté sur un câble coaxial désigné globalement par 3, un boîtier désigné globalement par 4, un manchon coudé désigné globalement par 5 et un capot de verrouillage désigné globalement par 6.This assembly 1 comprises in the example described, an angled coaxial connector generally designated 2 and mounted on a coaxial cable generally designated 3, a housing generally designated by 4, an elbow sleeve generally designated by 5 and a generally designated locking cap by 6.

On a représenté à la figure 4 le connecteur coaxial coudé 2.We have shown figure 4 the angled coaxial connector 2.

Ce connecteur coudé 2 comporte un contact central 7, un élément isolant 8 et un corps 9.This angled connector 2 comprises a central contact 7, an insulating element 8 and a body 9.

Le contact central 7 est, dans l'exemple décrit, coudé et réalisé d'une seule pièce selon la technologie dite « découpé-roulé ». Le contact central 7 est par exemple en bronze revêtu de métal, par exemple de nickel, d'or ou d'étain selon la zone du contact central concernée.The central contact 7 is, in the example described, bent and made in one piece according to the technology called "cut-rolled". The central contact 7 is for example bronze coated metal, for example nickel, gold or tin depending on the area of the central contact concerned.

Comme on peut le voir, le contact central 7 comporte à une extrémité 10 une portion de sertissage 11 comportant une section transversale en U ou en V avec deux branches 12 en regard pouvant être rabattues l'une vers l'autre autour du conducteur central du câble coaxial 3, comme décrit par la suite.As can be seen, the central contact 7 comprises at one end 10 a crimping portion 11 having a cross section in U or V with two branches 12 opposite which can be folded towards one another around the central conductor of the coaxial cable 3, as described later.

La portion de sertissage 11 repose, comme on peut le voir sur la figure 3, sur une portion d'appui 15, située à une extrémité 14 de l'élément isolant 8. L'élément isolant 8 est de forme coudé et par exemple réalisé d'une seule pièce, étant notamment réalisé en un matériau polymère haute performance.The crimping portion 11 rests, as can be seen on the figure 3 , on a support portion 15, located at one end 14 of the insulating element 8. The insulating element 8 is of bent shape and for example made in one piece, being in particular made of a high performance polymer material.

La portion d'appui 15 de l'élément isolant 8 comporte par exemple une face supérieure 16 pourvue d'un renfoncement agencé pour recevoir au moins partiellement la portion de sertissage 11 du contact central 7. La portion d'appui 15 comporte par exemple deux parois en regard 17 divergeant vers le bas, qui peuvent être planes ou comporter deux portions non parallèles.The bearing portion 15 of the insulating element 8 comprises for example an upper face 16 provided with a recess arranged to at least partially receive the crimping portion 11 of the central contact 7. The bearing portion 15 comprises for example two facing walls 17 diverging downwards, which may be flat or have two non-parallel portions.

L'élément isolant 8 comporte par exemple au niveau d'une portion cylindrique 18 des moyens permettant d'établir avec le contact central 7 une liaison à baïonnette.The insulating element 8 comprises for example at a cylindrical portion 18 means for establishing with the central contact 7 a bayonet connection.

Le corps 9 du connecteur coaxial 2 est dans l'exemple décrit coudé, comportant une première portion 20 s'étendant selon un axe (X) et recevant intérieurement la portion cylindrique 18 de l'élément isolant 8, et une deuxième portion 21 s'étendant selon un axe (Y) et portant la portion d'appui 15 de l'élément isolant 8.The body 9 of the coaxial connector 2 is in the example described bent, having a first portion 20 extending along an axis (X) and receiving internally the cylindrical portion 18 of the insulating member 8, and a second portion 21 s' extending along an axis (Y) and carrying the bearing portion 15 of the insulating element 8.

Dans l'exemple décrit, les axes (X) et (Y) sont perpendiculaires mais l'invention peut s'appliquer à toute disposition non parallèle des axes (X) et (Y).In the example described, the (X) and (Y) axes are perpendicular but the invention can be applied to any non-parallel arrangement of the (X) and (Y) axes.

Comme représenté à la figure 4, la première portion 20 du corps 9 peut être tubulaire. Cette portion 20 peut comporter au moins une, notamment deux, languette élastique 22 s'étendant selon l'axe (X).As represented in figure 4 the first portion 20 of the body 9 may be tubular. This portion 20 may comprise at least one, in particular two, elastic tongue 22 extending along the axis (X).

La deuxième portion 21 du corps 9 peut comporter une partie de support 23 recevant la partie d'appui 15 de l'élément isolant 8. Cette partie de support 23 comporte une section transversale par rapport à l'axe (Y) qui constitue une zone de raccordement et qui peut être par exemple sensiblement triangulaire, mais l'invention n'est pas limitée à une forme particulière de section transversale de la partie de support 23. Cette partie de support 23 est par exemple non cylindrique, étant dépourvue de bords définissant avec les parois latérales 17 de la portion d'appui 15 un dégagement tel que décrit dans le brevet EP 1 653 574 .The second portion 21 of the body 9 may comprise a support portion 23 receiving the bearing portion 15 of the insulating member 8. This support portion 23 has a cross section relative to the axis (Y) which constitutes a zone connection and which may be for example substantially triangular, but the invention is not limited to a particular cross-sectional shape of the support portion 23. This support portion 23 is for example non-cylindrical, being devoid of edges defining with the side walls 17 of the bearing portion 15 a clearance as described in the patent EP 1 653 574 .

La deuxième portion 21 peut comporter, similairement à ce qui a été décrit dans le brevet EP 1 653 574 , deux portions de sertissage 25 et 26 ayant chacune une section transversale par rapport à l'axe (Y) sensiblement en U ou en V.The second portion 21 may comprise, similarly to what has been described in the patent EP 1 653 574 , two crimping portions 25 and 26 each having a cross section relative to the axis (Y) substantially U or V.

La portion de sertissage 25, respectivement 26, comporte une paire de branches rabattables 25a et 25b, respectivement 26a et 26b, permettant le sertissage de la tresse de blindage, respectivement de la gaine isolante externe du câble coaxial 3, comme on le verra par la suite.The crimping portion 25, respectively 26, comprises a pair of foldable branches 25a and 25b, respectively 26a and 26b, for crimping the shielding braid, respectively the outer insulating sheath of the coaxial cable 3, as will be seen by the after.

On va maintenant décrire en référence à la figure 5 un manchon 5 selon un exemple de mise en oeuvre de l'invention.We will now describe with reference to the figure 5 a sleeve 5 according to an exemplary implementation of the invention.

Le manchon 5 est, dans l'exemple décrit, coudé, comportant une première portion tubulaire 30 s'étendant selon un premier axe du manchon (A1) et une deuxième portion 31 s'étendant selon un deuxième axe du manchon (A2), les premier et deuxième axes du manchon étant respectivement parallèles à l'axe (X) et à l'axe (Y) lorsque le connecteur coaxial 2 est reçu dans le manchon 5.The sleeve 5 is, in the example described, bent, having a first tubular portion 30 extending along a first axis of the sleeve (A 1 ) and a second portion 31 extending along a second axis of the sleeve (A 2 ). , the first and second axes of the sleeve being respectively parallel to the axis (X) and to the axis (Y) when the coaxial connector 2 is received in the sleeve 5.

Le manchon 5 peut être réalisé d'une seule pièce. Comme représenté à la figure 5, la première portion 30 peut comporter au niveau de la jonction avec la deuxième portion 31 une gorge 32 sur sa surface latérale extérieure. La gorge 32 s'étend par exemple sur tout le pourtour de l'axe (A1) et elle est bordée latéralement par deux collerettes 33 et 34.The sleeve 5 can be made in one piece. As represented in figure 5 , the first portion 30 may comprise at the junction with the second portion 31 a groove 32 on its outer side surface. The groove 32 extends for example all around the axis (A 1 ) and is bordered laterally by two flanges 33 and 34.

La collerette 33 comporte par exemple plusieurs portions discontinues séparées deux à deux par un évidement 36. Chaque portion de la collerette 33 peut s'étendre sur une certaine distance angulaire et les évidements 36 sont répartis sur le pourtour de la première portion 30 du manchon 5.The flange 33 comprises for example several discontinuous portions separated two by two by a recess 36. Each portion of the flange 33 may extend over a certain angular distance and the recesses 36 are distributed around the periphery of the first portion 30 of the sleeve 5. .

Le fond de la gorge 32 est dans l'exemple décrit pourvu d'une pluralité d'encoches 35 s'étendant parallèlement à l'axe (A1). Ces encoches 35 sont par exemple réparties uniformément dans le sens circonférentiel, étant dans l'exemple décrit espacées d'un angle mesuré depuis l'axe (A1) égal à 45°. L'invention n'est bien entendu pas limitée à une telle valeur d'angle.The bottom of the groove 32 is in the example described provided with a plurality of notches 35 extending parallel to the axis (A 1 ). These notches 35 are for example distributed uniformly in the circumferential direction, being in the example described spaced from an angle measured from the axis (A 1 ) equal to 45 °. The invention is of course not limited to such an angle value.

Comme représenté sur la figure 5, la première portion 30 du manchon 5 comporte par exemple sur sa surface intérieure deux rainures 37 s'étendant parallèlement à l'axe (A1) et destinées à coopérer avec les languettes élastiques 22 du corps 9 du connecteur 2. La deuxième portion 31 a, dans l'exemple décrit, une forme globalement parallélépipédique.As shown on the figure 5 , the first portion 30 of the sleeve 5 comprises for example on its inner surface two grooves 37 extending parallel to the axis (A 1 ) and intended to cooperate with the elastic tongues 22 of the body 9 of the connector 2. The second portion 31 a, in the example described, a generally parallelepiped shape.

Un logement 38 s'étendant parallèlement à l'axe (A2), comme représenté sur la figure 13, est ménagé dans la deuxième portion 31. Ce logement peut être ouvert vers l'extérieur, la deuxième portion 31 comportant par exemple au niveau de ce logement 38 une section transversale par rapport à l'axe (A2) en forme de U. La deuxième portion 31 comporte encore dans l'exemple décrit deux faces latérales 40 s'étendant parallèlement au deuxième axe (A2) et portant chacune un chanfrein 41 à une extrémité longitudinale et un décrochement 42 à leur autre extrémité longitudinale et dont le rôle sera décrit plus loin.A housing 38 extending parallel to the axis (A 2 ), as shown in FIG. figure 13 is housed in the second portion 31. This housing can be open to the outside, the second portion 31 having for example at this housing 38 a cross section relative to the axis (A 2 ) U-shaped. The second portion 31 further comprises in the example described two side faces 40 extending parallel to the second axis (A 2 ) and each bearing a chamfer 41 at one longitudinal end and a recess 42 at their other longitudinal end and whose role will be described later.

On va maintenant décrire en référence aux figures 6, 7 et 17 un boîtier 4 selon un exemple de mise en oeuvre de l'invention.We will now describe with reference to Figures 6, 7 and 17 a housing 4 according to an exemplary implementation of the invention.

Comme représenté sur les figures, ce boîtier 4 s'étend selon un axe longitudinal (Z) qui est parallèle à l'axe (X) lorsque l'ensemble 1 est assemblé.As shown in the figures, this housing 4 extends along a longitudinal axis (Z) which is parallel to the axis (X) when the assembly 1 is assembled.

Ce boîtier 4 est par exemple réalisé en polymère et il est évidé intérieurement, comportant un passage traversant selon l'axe (Z).This housing 4 is for example made of polymer and is hollowed out internally, having a through passage along the axis (Z).

Le boîtier 4 comporte par exemple des pattes élastiques 44 ménagées dans sa paroi au niveau d'une de ses extrémités longitudinales 61. Dans l'exemple décrit, les pattes 44 sont au nombre de deux et sont diamétralement opposées, mais l'invention n'est pas limitée à un nombre et à un positionnement précis de pattes 44.The housing 4 comprises, for example, resilient tabs 44 formed in its wall at one of its longitudinal ends 61. In the example described, the tabs 44 are two in number and are diametrically opposed, but the invention is not limited to a specific number and positioning of legs 44.

Comme représenté à la figure 17, le dessus du boîtier 4 peut comporter une zone 45 pour l'accouplement à un boîtier d'un ensemble de connexion complémentaire, cette zone 45 comportant un arceau 46 et une patte 47, montée pivotante sur le boîtier 4 autour d'un axe perpendiculaire à l'axe (Z) du boîtier par l'intermédiaire d'une articulation 63 et permettant d'assurer une fonction de verrouillage de l'ensemble de connexion 1 avec un boîtier d'un ensemble de connexion complémentaire.As represented in figure 17 , the top of the housing 4 may comprise a zone 45 for coupling to a housing of a complementary connection assembly, this zone 45 including a hoop 46 and a tab 47, pivotally mounted on the housing 4 around a perpendicular axis to the axis (Z) of the housing via a hinge 63 and to provide a locking function of the connection assembly 1 with a housing of a complementary connection assembly.

L'arceau 46 s'étend dans l'exemple décrit perpendiculairement à l'axe (Z) et sur une portion de la longueur du boîtier 4 depuis une l'extrémité longitudinale 60 de ce dernier, ladite extrémité longitudinale 60 venant au contact du boîtier d'un ensemble de connexion complémentaire lors d'un accouplement à ce dernier.The hoop 46 extends in the example described perpendicularly to the axis (Z) and a portion of the length of the housing 4 from a longitudinal end 60 of the latter, said longitudinal end 60 coming into contact with the housing of a complementary connection assembly during a coupling to the latter.

Comme représenté à la figure 17, l'arceau 46 comporte, au niveau de l'extrémité 60, une découpe 64, par exemple en forme de U. Cette découpe 64 est dans l'exemple illustré située en regard d'une extrémité longitudinale 65 de la patte 47 et elle libère un espace E favorisant le pivotement de l'extrémité 65 de la patte 47 dans ledit espace E lorsque la patte 47 est actionnée pour le verrouillage/déverrouillage de l'ensemble de connexion 1.As represented in figure 17 the hoop 46 comprises, at the end 60, a cutout 64, for example in the shape of a U. This cutout 64 is in the illustrated example located opposite a longitudinal end 65 of the tab 47 and releases a space E promoting the pivoting of the end 65 of the tab 47 in said space E when the tab 47 is actuated for locking / unlocking the connection assembly 1.

Comme on peut le voir, la zone 45 comporte également une portion ouverte 49 sur laquelle la patte 47 n'est pas recouverte par l'arceau 46, favorisant le pivotement de l'autre extrémité longitudinale 66 de la patte 47.As can be seen, the zone 45 also has an open portion 49 on which the tab 47 is not covered by the arch 46, favoring the pivoting of the other longitudinal end 66 of the tab 47.

Comme représenté aux figures 6 et 7, la surface latérale intérieure du boîtier 4 peut comporter un ou plusieurs pions 48 qui peuvent être répartis de façon uniforme sur le pourtour du boîtier ou non. Les pions 48 sont par exemple disposés sensiblement sur un même pourtour de la surface latérale intérieure du boîtier 4, par exemple à proximité ou au niveau de l'extrémité longitudinale 61 du boîtier 4 opposée à l'extrémité longitudinale 60. Les pions 48 et les pattes 44 sont par exemple situés sur un même pourtour de la surface latérale intérieure du boîtier 4, dans l'exemple illustré au niveau de l'extrémité longitudinale 61.As represented in Figures 6 and 7 , the inner side surface of the housing 4 may comprise one or more pins 48 which may be distributed uniformly around the periphery of the housing or not. The pins 48 are for example disposed substantially on the same periphery of the inner side surface of the housing 4, for example near or at the longitudinal end 61 of the housing 4 opposite the longitudinal end 60. The pins 48 and the tabs 44 are for example located on the same periphery of the inner side surface of the housing 4, in the example shown at the longitudinal end 61.

On va maintenant décrire en référence aux figures 8 et 9 un exemple de montage du boîtier 4 sur le manchon 5. Comme représenté à la figure 8, le boîtier 4 peut coulisser par rapport à la première portion 30 du manchon 5 sous l'effet d'une force F. Lors de ce mouvement de coulissement, les pions 48 peuvent pénétrer au travers des évidements 36, ayant par exemple une dimension transversale par rapport l'axe (Z) inférieure à celle des évidements 36. A l'issue de cette traversée des évidements 36 par les pions 48, les pattes 44 du boîtier 4 peuvent venir s'encliqueter dans la gorge 32, assurant ainsi la fixation du boîtier 4 sur le manchon 5.We will now describe with reference to figures 8 and 9 an example of mounting the housing 4 on the sleeve 5. As shown in FIG. figure 8 , the housing 4 can slide relative to the first portion 30 of the sleeve 5 under the effect of a force F. During this sliding movement, the pins 48 can penetrate through the recesses 36, having for example a transverse dimension relative to the axis (Z) less than that of the recesses 36. At the end of this passage of the recesses 36 by the pins 48, the tabs 44 of the housing 4 can snap into the groove 32, thereby securing of the housing 4 on the sleeve 5.

A l'issue de ce mouvement de coulissement, les pions 48 sont maintenus par friction dans des encoches 35 de la gorge 32. Un utilisateur peut alors déplacer en rotation le boîtier 4 autour du manchon 5 en amenant les pions 48 dans d'autres encoches 35 de la gorge 32.At the end of this sliding movement, the pins 48 are held by friction in notches 35 of the groove 32. A user can then rotate the housing 4 around the sleeve 5 by bringing the pins 48 into other notches 35 of the throat 32.

Le capot de verrouillage 6 est par exemple réalisé en métal, par exemple en acier inoxydable ou en laiton. Le capot 6 présente dans l'exemple décrit une forme en U, comportant un dos 50 destiné à fermer le logement 38 et deux faces parallèles 51, toutes deux perpendiculaires au dos 50 et destinées à recouvrir extérieurement les faces 40 de la deuxième portion 31 du manchon 5 lorsque le capot est fermé.The locking cap 6 is for example made of metal, for example stainless steel or brass. The cover 6 has in the example described a U-shape, comprising a back 50 intended to close the housing 38 and two parallel faces 51, both perpendicular to the back 50 and intended to cover externally the faces 40 of the second portion 31 of the sleeve 5 when the hood is closed.

Comme on peut le voir sur la figure 11, ces faces 51 comportent chacune un décrochement 52 destiné à coopérer avec le décrochement 42 des faces 40 de la deuxième portion 31 du manchon 5, de façon à assurer la fermeture du capot de verrouillage 6 sur le manchon 5.As can be seen on the figure 11 these faces 51 each comprise a recess 52 intended to cooperate with the recess 42 of the faces 40 of the second portion 31 of the sleeve 5, so as to ensure the closure of the locking cap 6 on the sleeve 5.

Dans l'exemple décrit, le capot 6 est monté pivotant sur le manchon 5, les faces 51 comportant chacune une ouverture recevant un des chanfreins 41.In the example described, the cover 6 is pivotally mounted on the sleeve 5, the faces 51 each having an opening receiving one of the chamfers 41.

Le dos 50 du capot de verrouillage 6 peut comporter à une première extrémité une patte 54 représentée à la figure 11, destinée à coopérer avec un relief du manchon 5 pour maintenir le capot 6 en position ouverte dans une position prédéfinie et une patte élastique 53 située à l'autre extrémité du dos 50.The back 50 of the locking cap 6 may comprise at a first end a tab 54 shown in FIG. figure 11 , intended to cooperate with a relief of the sleeve 5 to maintain the cover 6 in the open position in a predefined position and an elastic tab 53 located at the other end of the back 50.

Cette patte élastique 53 est par exemple configurée pour exercer une force s'opposant à la fermeture du capot de verrouillage 6 sur le manchon 5, le capot n'étant alors pas fermé tant qu'une force suffisante n'a pas été exercée sur celui-ci.This elastic tab 53 is for example configured to exert a force opposing the closing of the locking cap 6 on the sleeve 5, the hood then not being closed until sufficient force has been exerted on the -this.

On va maintenant décrire en référence aux figures 12 à 16 un exemple d'assemblage d'un ensemble 1 selon l'invention.We will now describe with reference to Figures 12 to 16 an example of assembly of a set 1 according to the invention.

Comme représenté à la figure 12, le câble coaxial 3 peut être serti sur le connecteur coaxial 2 à l'aide d'un outil à sertir 55 représenté schématiquement en section transversale. Cet outil 55 comporte par exemple une cavité 56 définissant une surface d'appui 57 capable de s'appliquer sur la portion de sertissage 11 du contact central 7. La surface d'appui 57 peut présenter une section transversale évasée vers le bas, au moins au voisinage d'une ouverture par laquelle s'engage la portion de sertissage 11 lors du sertissage.As represented in figure 12 , the coaxial cable 3 can be crimped on the coaxial connector 2 with a crimping tool 55 shown schematically in cross section. This tool 55 comprises for example a cavity 56 defining a bearing surface 57 capable of being applied to the crimping portion 11 of the central contact 7. The bearing surface 57 may have a cross section flared downwards, at least in the vicinity of an opening through which the crimping portion 11 engages during crimping.

La surface d'appui 57 de l'outil 55 comporte par exemple deux parois courbes en regard se raccordant au fond de la cavité 56. La forme de la surface d'appui 57 peut être choisie de manière à épouser sensiblement la forme d'une partie au moins des parois latérales 17 de la portion d'appui 15 de l'élément isolant 8.The bearing surface 57 of the tool 55 comprises, for example, two facing curved walls connecting to the bottom of the cavity 56. The shape of the bearing surface 57 can be chosen so as to substantially conform to the shape of a at least part of the side walls 17 of the bearing portion 15 of the insulating element 8.

Lors du sertissage du conducteur central du câble coaxial avec le contact central 7, l'outil 55 peut être déplacé suivant un axe perpendiculaire à l'axe (Y), les branches 12 de la partie de sertissage 11 étant rabattues de manière progressive afin d'éviter un flambage éventuel de ces branches vers l'extérieur. Les portions de sertissage 25 et 26 sont similairement serties, respectivement sur la tresse de blindage et la gaine isolante externe du câble coaxial 2 à l'aide des différentes parties de l'outil. Le connecteur 2 monté sur le câble coaxial 3 est ensuite introduit dans le manchon 5 sur lequel a été préalablement encliqueté le boîtier 4, comme représenté à la figure 13.When crimping the central conductor of the coaxial cable with the central contact 7, the tool 55 can be moved along an axis perpendicular to the axis (Y), the branches 12 of the crimping portion 11 being folded down gradually so as to avoid any buckling of these branches to the outside. The crimping portions 25 and 26 are similarly crimped, respectively on the shielding braid and the outer insulating sheath of the coaxial cable 2 with the aid of the various parts of the tool. The connector 2 mounted on the coaxial cable 3 is then inserted into the sleeve 5 on which the housing 4 has been previously locked, as shown in FIG. figure 13 .

Le capot 6 peut alors être rabattu de façon à fermer le logement 38 pour assurer le maintien mécanique du connecteur monté sur le câble dans le manchon 5 et assurer une continuité électrique, de façon à ce que l'ensemble soit dans la configuration représentée à la figure 15.The cover 6 can then be folded so as to close the housing 38 to ensure the mechanical retention of the connector mounted on the cable in the sleeve 5 and ensure a electrical continuity, so that the assembly is in the configuration shown in FIG. figure 15 .

Comme représenté à la figure 16, la patte 53 du capot 6 vient alors en appui contre le corps 9 du connecteur coaxial 2 et tend à maintenir le capot 6 en position ouverte tant qu'un effort suffisant n'a pas été exercé sur ce dernier.As represented in figure 16 , the tab 53 of the cover 6 then bears against the body 9 of the coaxial connector 2 and tends to keep the cover 6 in the open position as long as sufficient force has not been exerted on the latter.

L'invention n'est pas limitée aux exemples qui viennent d'être décrits.The invention is not limited to the examples which have just been described.
