Abstract

The device has a spring i.e. helical spring, with an end (32) and another end connected to mobile parts (20, 21) e.g. rings, respectively. The spring and the parts are arranged such that turning one of the parts in a rotational direction and the other part in another rotational direction increases the inside diameter of the spring, where the latter direction is opposite to the former direction. The spring and the parts are arranged such that turning the former part in the latter direction or turning the latter part in the former direction decreases the inside diameter of the spring.

Description

La présente invention a pour objet un dispositif pour la connexion de deux éléments de connecteur complémentaires, par exemple un corps à une embase ou à une prise à câbler. Les éléments de connecteur sont par exemple des éléments coaxiaux, notamment un corps coaxial et une embase coaxiale.The present invention relates to a device for connecting two complementary connector elements, for example a body to a base or a socket to be wired. The connector elements are, for example, coaxial elements, in particular a coaxial body and a coaxial base.

Il est connu de réaliser une telle connexion par l'intermédiaire d'une bague montée rotative sur un corps, cette bague comportant un filetage destiné à être vissé sur un filetage correspondant de l'embase. Le serrage et le desserrage de la bague s'obtiennent en tournant celle-ci en rotation selon deux sens de rotation différents.It is known to make such a connection via a ring rotatably mounted on a body, this ring having a thread intended to be screwed on a corresponding thread of the base. Clamping and loosening of the ring is achieved by rotating the ring in two different directions of rotation.

De telles solutions ne permettent pas d'éviter des desserrages intempestifs de la bague, un tel desserrage affectant la connexion réalisée et se produisant en particulier sous l'effet de vibrations ou de rotation du câble sur lequel est monté le corps.Such solutions do not prevent unwanted loosening of the ring, such loosening affecting the connection made and occurring in particular under the effect of vibration or rotation of the cable on which the body is mounted.

Il existe un besoin pour disposer d'un dispositif pour la connexion d'un corps à une embase réduisant les risques de desserrage intempestif.There is a need to have a device for connecting a body to a base reducing the risk of inadvertent loosening.

L'invention a pour but de répondre à ce besoin et, elle y parvient, selon l'un de ses aspects, grâce à un dispositif pour la connexion d'un premier et d'un deuxième élément de connecteur complémentaires, notamment un corps et une embase, comportant une première et une deuxième pièce mobiles en rotation l'une par rapport à l'autre, caractérisé par le fait qu'il comprend un ressort ayant une première extrémité reliée à la première pièce et une deuxième extrémité reliée à la deuxième pièce, le ressort, la première pièce et la deuxième pièce étant tels que la rotation selon un premier sens de rotation de la première pièce ou selon un deuxième sens de rotation, opposé au premier sens de rotation, de la deuxième pièce augmente le diamètre intérieur du ressort et, le ressort, la première pièce et la deuxième pièce étant tels que la rotation selon le deuxième sens de rotation de la première pièce ou selon le premier sens de rotation de la deuxième pièce diminue le diamètre intérieur du ressort.The aim of the invention is to meet this need and, in one of its aspects, it achieves this by means of a device for connecting a first and a second complementary connector element, in particular a body and a a base, comprising a first and a second part movable in rotation relative to each other, characterized in that it comprises a spring having a first end connected to the first part and a second end connected to the second end; piece, the spring, the first piece and the second piece being such that the rotation in a first direction of rotation of the first piece or in a second direction of rotation, opposite the first direction of rotation, of the second piece increases the inside diameter spring and the spring, the first piece and the second piece being such that the rotation in the second direction of rotation of the first piece or in the first direction of rotation of the second I play reduces the inside diameter of the spring.

Grâce à l'invention, la première et la deuxième pièces agissent de façon complémentaire l'une par rapport à l'autre pour connecter ou déconnecter les deux éléments de connecteur à l'aide du dispositif.Thanks to the invention, the first and second parts act complementary to each other to connect or disconnect the two connector elements with the device.

L'invention permet de réduire les risques que des vibrations et/ou un couple auxquels sont soumis le câble relié à un des éléments de connecteur complémentaires ne desserrent les premier et deuxième éléments de connecteur.The invention makes it possible to reduce the risks that vibrations and / or a torque to which the cable connected to one of the complementary connector elements are subjected loosen the first and second connector elements.

Selon un premier mode de réalisation de l'invention, la première pièce comporte avantageusement une portion filetée enroulée selon un sens d'enroulement inverse du sens d'enroulement du ressort. Le sens d'enroulement du filetage de la première pièce et le sens d'enroulement du ressort peuvent ainsi être différents, la première pièce comportant par exemple un filetage à droite, respectivement à gauche, et le ressort étant par exemple enroulé à gauche, respectivement à droite.According to a first embodiment of the invention, the first piece advantageously comprises a threaded portion wound in a reverse winding direction of the winding direction of the spring. The winding direction of the threading of the first part and the direction of winding of the spring can thus be different, the first part comprising for example a right-hand thread, respectively on the left, and the spring being for example wound on the left, respectively to the right.

La première pièce s'étend avantageusement selon un axe longitudinal, la première extrémité du ressort est avantageusement reçue dans un premier trou ménagé dans la paroi de la première pièce à proximité d'une extrémité longitudinale de la première pièce et la deuxième extrémité du ressort traverse avantageusement un deuxième trou ménagé dans la paroi de la première pièce à distance de ladite extrémité longitudinale.The first part advantageously extends along a longitudinal axis, the first end of the spring is advantageously received in a first hole formed in the wall of the first piece near a longitudinal end of the first piece and the second end of the spring passes through advantageously a second hole formed in the wall of the first piece at a distance from said longitudinal end.

Le premier trou peut être longitudinalement disposé entre ladite extrémité longitudinale et le deuxième trou. Ladite extrémité longitudinale est par exemple celle destinée à venir au contact du deuxième élément de connecteur lors de la connexion à ce dernier du premier élément de connecteur sur lequel le dispositif est monté.The first hole may be longitudinally disposed between said longitudinal end and the second hole. Said longitudinal end is for example that intended to come into contact with the second connector element when connecting to the latter of the first connector element on which the device is mounted.

Une telle configuration de la première pièce, de la deuxième pièce et du ressort permet le fonctionnement complémentaire précité des première et deuxième pièces.Such a configuration of the first part, the second part and the spring allows the above complementary operation of the first and second parts.

Selon un deuxième mode de réalisation de l'invention, le dispositif comporte une portion filetée enroulée selon le même sens d'enroulement que le ressort. La première pièce s'étend avantageusement selon un axe longitudinal, la première extrémité du ressort est avantageusement reçue dans un premier trou ménagé dans la paroi de la première pièce à distance d'une extrémité longitudinale de la première pièce et la deuxième extrémité du ressort traverse avantageusement un deuxième trou ménagé dans la paroi de la première pièce à proximité de ladite extrémité longitudinale.According to a second embodiment of the invention, the device comprises a threaded portion wound in the same winding direction as the spring. The first part advantageously extends along a longitudinal axis, the first end of the spring is advantageously received in a first hole formed in the wall of the first piece at a distance from a longitudinal end of the first piece and the second end of the spring passes through advantageously a second hole formed in the wall of the first piece near said longitudinal end.

Le deuxième trou peut être longitudinalement disposé entre ladite extrémité longitudinale et le premier trou. Ladite extrémité longitudinale est par exemple celle destinée à venir au contact du deuxième élément de connecteur lors de la connexion à ce dernier du premier élément de connecteur sur lequel le dispositif est monté.The second hole may be longitudinally disposed between said longitudinal end and the first hole. Said longitudinal end is for example that intended to come into contact with the second connector element when connecting to the latter of the first connector element on which the device is mounted.

Une telle configuration de la première pièce, de la deuxième pièce et du ressort permet le fonctionnement complémentaire précité des première et deuxième pièces.Such a configuration of the first part, the second part and the spring allows the above complementary operation of the first and second parts.

La portion filetée selon le deuxième mode de réalisation de l'invention peut être ménagée dans la première pièce.The threaded portion according to the second embodiment of the invention may be formed in the first piece.

En variante, la portion filetée selon le deuxième mode de réalisation est ménagée dans le ressort. La portion filetée est par exemple ménagée dans la surface intérieure du ressort.Alternatively, the threaded portion according to the second embodiment is formed in the spring. The threaded portion is for example formed in the inner surface of the spring.

Selon cette variante, le fonctionnement complémentaire des première et deuxième pièces est permis par la configuration du ressort, ce dernier assurant seul l'enfichage des premier et deuxième éléments de connecteur et l'anti-desserrage de l'un par rapport à l'autre.According to this variant, the complementary operation of the first and second parts is allowed by the configuration of the spring, the latter ensuring only the plugging of the first and second connector elements and the anti-loosening of one relative to the other .

Lorsque la portion filetée enroulée dans le même sens que le ressort est portée par ledit ressort, il n'est plus nécessaire de prévoir une telle portion filetée sur la première pièce, ce qui permet de réduire la longueur de la première pièce et ainsi le poids de la première pièce. On peut obtenir un dispositif plus léger et plus compact. Le ressort est avantageusement reçu à l'intérieur des première et deuxième pièces. Le ressort peut être hélicoïdal. Le ressort peut être réalisé avec un fil de section cylindrique ou, en variante, avec un ruban plat.When the threaded portion wound in the same direction as the spring is carried by said spring, it is no longer necessary to provide such a threaded portion on the first piece, which reduces the length of the first piece and thus the weight of the first piece. A lighter and more compact device can be obtained. The spring is advantageously received inside the first and second parts. The spring can be helical. The spring can be made with a wire of cylindrical section or, alternatively, with a flat ribbon.

Le ressort, notamment lorsqu'il porte la portion filetée, peut encore être réalisé avec un fil de section trapézoïdale, une telle section permettant une meilleure coopération avec une portion filetée complémentaire.The spring, especially when carrying the threaded portion, can still be made with a trapezoidal section wire, such a section for better cooperation with a complementary threaded portion.

Le deuxième trou présente avantageusement une dimension angulaire supérieure au diamètre du fil du ressort.The second hole advantageously has an angular dimension greater than the diameter of the spring wire.

La deuxième pièce comporte avantageusement au moins une partie entourant extérieurement au moins une partie de la première pièce. La première pièce est par exemple une bague et la deuxième pièce peut être une bague ou une portion de bague, par exemple plus ou moins étendue.The second part advantageously comprises at least one part surrounding externally at least a part of the first part. The first piece is for example a ring and the second piece may be a ring or a ring portion, for example more or less extended.

L'invention a encore pour objet, selon un autre de ses aspects, un ensemble caractérisé par le fait qu'il comporte:

  • un premier élément de connecteur, notamment un corps,
  • un deuxième élément de connecteur complémentaire du premier élément de connecteur, notamment une embase et,
  • un dispositif monté sur le premier élément de connecteur et apte à connecter ce dernier au deuxième élément de connecteur.
Another aspect of the invention is, according to another of its aspects, an assembly characterized by the fact that it comprises:
  • a first connector element, in particular a body,
  • a second complementary connector element of the first connector element, in particular a base and,
  • a device mounted on the first connector element and adapted to connect the latter to the second connector element.

Le diamètre intérieur du ressort au repos est avantageusement inférieur à la plus grande dimension transversale du deuxième élément de connecteur.The inner diameter of the spring at rest is advantageously less than the largest transverse dimension of the second connector element.

Le deuxième élément de connecteur peut comporter une portion filetée complémentaire de celle du dispositif, de manière à ce que les deux portions filetées puissent coopérer. Lorsque la portion filetée du dispositif est portée par le ressort, le pas de ce dernier est avantageusement choisi pour coopérer avec le pas de la portion filetée complémentaire.The second connector element may comprise a threaded portion complementary to that of the device, so that the two threaded portions can cooperate. When the threaded portion of the device is carried by the spring, the pitch of the latter is advantageously chosen to cooperate with the pitch of the complementary threaded portion.

Lorsque la portion filetée du dispositif est portée par le ressort, le diamètre intérieur du ressort au repos peut être configuré pour exercer une friction sur la portion filetée complémentaire.When the threaded portion of the device is carried by the spring, the inner diameter of the spring at rest can be configured to exert friction on the complementary threaded portion.

Dans ce qui suit et ce qui précède, on désigne par « ressort au repos » la configuration du ressort lorsqu'il ne repose pas contre le deuxième élément de connecteur et n'est soumis à aucune force extérieure tendant à modifier son diamètre intérieur.In what follows and the foregoing, the term "spring at rest" designates the spring when it does not rest against the second connector element and is not subject to any external force tending to change its inside diameter.

Par « plus grande dimension transversale du deuxième élément de connecteur», on désigne la plus grande dimension extérieure transversale, par rapport à l'axe longitudinal du deuxième élément de connecteur, de la partie du deuxième élément de connecteur venant au contact du premier élément de connecteur lors de la connexion.By "greater transverse dimension of the second connector element" is meant the largest external transverse dimension, relative to the longitudinal axis of the second connector element, of the portion of the second connector element engaging the first element of the connector. connector when connecting.

La distance angulaire sur laquelle s'étend le deuxième trou dans la paroi de la première pièce est avantageusement supérieure ou égale à la rotation angulaire de la deuxième extrémité du ressort permettant d'amener le diamètre intérieur du ressort à une valeur supérieure à la plus grande dimension transversale du deuxième élément de connecteur.The angular distance over which the second hole extends in the wall of the first part is advantageously greater than or equal to the angular rotation of the second end of the spring making it possible to bring the inner diameter of the spring to a value greater than the largest transverse dimension of the second connector element.

La rotation selon le premier sens de rotation de la première pièce permet non seulement de fixer, notamment visser, la première pièce sur le deuxième élément de connecteur, mais également, du fait de la friction du ressort sur la surface extérieure du deuxième élément de connecteur, d'augmenter le diamètre intérieur du ressort, permettant que le ressort puisse venir se positionner autour de la portion du deuxième élément de connecteur présentant la plus grande dimension transversale. Une fois le ressort en place autour de ladite portion du deuxième élément de connecteur, en cas d'arrêt de la rotation de la première pièce, le ressort vient s'appliquer contre le deuxième élément de connecteur, étant alors précontraint contre ce dernier et exerçant un serrage sur celui-ci.The rotation according to the first direction of rotation of the first part makes it possible not only to fix, in particular screw, the first part on the second connector element, but also, because of the friction of the spring on the outer surface of the second connector element , to increase the inner diameter of the spring, allowing the spring can come to be positioned around the portion of the second connector element having the largest transverse dimension. Once the spring in place around said portion of the second connector element, in case of stopping the rotation of the first piece, the spring is applied against the second connector element, being then prestressed against the latter and exerting a clamping on it.

Si un opérateur agit alors en tournant la première pièce selon le deuxième sens de rotation opposé au premier, la diminution du diamètre intérieur du ressort accroît encore le serrage de ce dernier contre le deuxième élément de connecteur, rendant impossible tout desserrage intempestif. Pour déconnecter les deux éléments de connecteur, un opérateur peut alors agir sur la deuxième pièce selon le deuxième sens de rotation, augmentant alors le diamètre intérieur du ressort, ce qui permet la déconnexion de l'ensemble.If an operator then acts by rotating the first part in the second direction of rotation opposite to the first, the decrease in the inner diameter of the spring further increases the clamping of the latter against the second connector element, making any inadvertent loosening impossible. To disconnect the two connector elements, an operator can then act on the second part in the second direction of rotation, thereby increasing the inner diameter of the spring, which allows the disconnection of the assembly.

La première pièce et/ou la deuxième pièce peuvent être réalisées en matière plastique.The first piece and / or the second piece can be made of plastic.

Le premier élément de connecteur, notamment le corps, et le dispositif sont avantageusement deux pièces distinctes.The first connector element, in particular the body, and the device are advantageously two separate parts.

En variante, le premier élément de connecteur, notamment le corps, et le dispositif peuvent être réalisés d'une seule pièce.In a variant, the first connector element, in particular the body, and the device can be made in one piece.

Les deux éléments de connecteur complémentaires sont avantageusement des éléments coaxiaux ou multicontact.The two complementary connector elements are advantageously coaxial or multicontact elements.

L'invention pourra être mieux comprise au vu de la description qui va suivre d'exemples non limitatifs de mise en oeuvre de celle-ci et à l'examen du dessin annexé sur lequel :

  • la figure 1 est une vue en perspective d'un ensemble selon un premier mode de réalisation de l'invention représenté de façon schématique,
  • la figure 2 est une vue analogue à la figure 1 d'un ensemble sans représentation de la deuxième pièce,
  • les figures 3 et 4 sont des vues en coupe selon différents plans longitudinaux de l'ensemble de la figure 1 lorsque les deux éléments de connecteur sont connectés et,
  • la figure 5 est une vue en coupe d'un deuxième mode de réalisation de l'invention représenté de façon schématique.
The invention will be better understood in view of the following description of non-limiting examples of implementation thereof and to the examination of the appended drawing in which:
  • the figure 1 is a perspective view of an assembly according to a first embodiment of the invention shown schematically,
  • the figure 2 is a view similar to the figure 1 a set without representation of the second piece,
  • the figures 3 and 4 are sectional views along different longitudinal planes of the entire figure 1 when both connector elements are connected and,
  • the figure 5 is a sectional view of a second embodiment of the invention shown schematically.

On a représenté à la figure 1 un ensemble désigné globalement par 1 selon un premier mode de réalisation de l'invention.We have shown figure 1 a set generally designated 1 according to a first embodiment of the invention.

Cet ensemble 1 comporte un premier élément de connecteur 2, apte à être connecté à un deuxième élément de connecteur complémentaire désigné globalement par 3 par l'intermédiaire d'un dispositif désigné globalement par 4. Dans l'exemple décrit, mais de façon non limitative, le premier élément de connecteur 2 est un corps et le deuxième élément de connecteur 3 est une embase. Dans une variante, le deuxième élément de connecteur 3 est une prise à câbler.This assembly 1 comprises a first connector element 2, capable of being connected to a second complementary connector element generally designated by 3 through a device generally designated by 4. In the example described, but not limited to, the first connector element 2 is a body and the second connector element 3 is a base. In a variant, the second connector element 3 is a socket to be wired.

Le corps 2 et l'embase 3 sont, dans l'exemple décrit, des éléments coaxiaux dont la structure interne qui comprend un contact central reçu dans un contact extérieur avec interposition d'un isolant n'a pas été représentée par souci de clarté sur les figures 1 à 4.The body 2 and the base 3 are, in the example described, coaxial elements whose internal structure which comprises a central contact received in an external contact with the interposition of an insulator has not been shown for the sake of clarity on the Figures 1 to 4 .

Le corps 2 est par exemple de forme globalement tubulaire autour d'un axe longitudinal X, et présente une section transversale décroissant par palier au fur et à mesure que l'on se rapproche de l'extrémité avant 5 du corps 2, ladite extrémité 5 désignant l'extrémité longitudinale du corps 2 venant au contact de l'embase 3 lors d'une connexion du corps 2 à l'embase 3.The body 2 is for example of generally tubular shape about a longitudinal axis X, and has a decreasing cross section by step as one approaches the front end 5 of the body 2, said end 5 designating the longitudinal end of the body 2 coming into contact with the base 3 during a connection of the body 2 to the base 3.

Comme représenté aux figures 3 et 4, un premier logement annulaire est ménagé dans la paroi latérale extérieure du corps 2 pour recevoir un jonc 6 et un deuxième logement annulaire est ménagé dans la paroi latérale extérieure du corps 2 entre le premier logement précité et l'extrémité avant 5 du corps 2, le deuxième logement recevant un joint annulaire 7, qui est par exemple réalisé en silicone.As represented in figures 3 and 4 a first annular housing is formed in the outer side wall of the body 2 to receive a rod 6 and a second annular housing is formed in the outer side wall of the body 2 between the aforementioned first housing and the front end 5 of the body 2, the second housing receiving an annular seal 7, which is for example made of silicone.

L'embase 3 comporte une platine 9 de fixation à un panneau non représenté, cette platine étant pourvue de trous 10 permettant le passage de vis, par exemple. Une partie tubulaire 12 s'étendant autour d'un axe confondu avec l'axe X du corps lorsque le corps 2 est connecté à l'embase 3 s'étend depuis cette platine 9 vers l'avant de l'embase 3.The base 3 comprises a plate 9 for attachment to a not shown panel, this plate being provided with holes 10 allowing the passage of screws, for example. A tubular portion 12 extending around an axis coinciding with the axis X of the body when the body 2 is connected to the base 3 extends from this plate 9 towards the front of the base 3.

On désigne par « avant de l'embase » le côté de l'embase venant au contact du corps 2 lors de la connexion du corps à l'embase. Comme représenté sur les figures 3 et 4, la partie tubulaire 12 de l'embase 3 comporte une portion 14 s'étendant depuis la platine 9 et présentant un diamètre extérieur Di, Di définissant la plus grande dimension transversale de l'embase 3.The term "front of the base" refers to the side of the base coming into contact with the body 2 when connecting the body to the base. As shown on figures 3 and 4 , the tubular portion 12 of the base 3 comprises a portion 14 extending from the plate 9 and having an outer diameter D i , D i defining the largest transverse dimension of the base 3.

Entre la portion 14 et l'extrémité avant 15 de l'embase, l'embase 3 comporte une portion 16 présentant un filetage extérieur 17.Between the portion 14 and the front end 15 of the base, the base 3 comprises a portion 16 having an external thread 17.

On va maintenant décrire un exemple de dispositif 4 pour la connexion du corps 2 à l'embase 3. Ce dispositif 4 comporte une première pièce 20, qui est dans l'exemple illustrée une bague, montée mobile en rotation par rapport au corps 2 autour de l'axe X du corps 2. La première bague 20 peut n'être mobile qu'en rotation autour de l'axe X par rapport au corps 2.We will now describe an example of device 4 for the connection of the body 2 to the base 3. This device 4 comprises a first part 20, which is in the example shown a ring, rotatably mounted relative to the body 2 around of the axis X of the body 2. The first ring 20 can be mobile only in rotation about the axis X with respect to the body 2.

Dans une variante non représentée, la première bague 20 et le corps 2 sont réalisés d'une seule pièce.In a variant not shown, the first ring 20 and the body 2 are made in one piece.

Le dispositif 4 comporte encore une deuxième pièce 21 montée mobile en rotation par rapport à la première bague 20. Cette deuxième pièce 21 est dans l'exemple illustré une bague mais pourrait, en variante, être une portion de bague, cette portion pouvant être plus ou moins étendue autour de l'axe X.The device 4 further comprises a second part 21 mounted to rotate with respect to the first ring 20. This second piece 21 is in the example illustrated a ring but could alternatively be a ring portion, this portion being able to be more or less extended around the X axis.

Comme on peut le voir, la première bague 20 peut s'étendre tout autour d'une portion du corps 2, ladite portion du corps 2 s'étendant depuis l'extrémité avant 5 de celui-ci. La première bague 20 présente par exemple un bourrelet annulaire 23 dont la surface extérieure est configurée pour définir une zone de préhension, cette surface extérieure étant par exemple obtenue par moletage ou par l'aménagement d'une zone rugueuse. La première bague 20 comporte encore dans l'exemple illustré, une zone médiane 24 dont la paroi intérieure présente un filetage 25 pour coopérer avec le filetage 17 décrit précédemment.As can be seen, the first ring 20 can extend all around a portion of the body 2, said portion of the body 2 extending from the front end 5 thereof. The first ring 20 has for example an annular bead 23 whose outer surface is configured to define a gripping zone, this outer surface being for example obtained by knurling or by the development of a rough zone. The first ring 20 further comprises in the illustrated example, a central zone 24 whose inner wall has a thread 25 to cooperate with the thread 17 described above.

La première bague 20 peut comporter une partie avant 26 s'étendant au-delà de l'extrémité avant 5 du corps 2.The first ring 20 may comprise a front portion 26 extending beyond the front end 5 of the body 2.

La deuxième bague 21 s'étend, dans l'exemple décrit, autour de la partie avant 26 de la première bague 21, cette deuxième bague 21 comportant en outre un rebord 29 recouvrant l'extrémité avant 33 de la partie avant 26. La deuxième bague comporte également dans l'exemple illustré, à son extrémité opposée au rebord 29, un bourrelet annulaire 28 définissant une zone de préhension obtenue comme la zone 23.The second ring 21 extends, in the example described, around the front portion 26 of the first ring 21, this second ring 21 further comprising a flange 29 covering the front end 33 of the front portion 26. The second In the example shown, the ring also comprises, at its end opposite the flange 29, an annular bead 28 defining a gripping zone obtained as the zone 23.

La deuxième bague 21 est maintenue sur la première bague 20 par coopération de reliefs 40 et 41, appartenant respectivement à la première et à la deuxième bague. Dans l'exemple décrit, la première bague 20 est réalisée d'une seule pièce, tout comme la deuxième bague 21.The second ring 21 is held on the first ring 20 by cooperation of reliefs 40 and 41, respectively belonging to the first and second ring. In the example described, the first ring 20 is made in one piece, just like the second ring 21.

Comme représenté sur les figures, le dispositif 4 comporte un ressort 30 qui est dans l'exemple décrit un ressort hélicoïdal. Ce ressort 30 est par exemple reçu à l'intérieur de la première bague 20.As shown in the figures, the device 4 comprises a spring 30 which is in the example described a helical spring. This spring 30 is for example received inside the first ring 20.

Selon le premier mode de réalisation de l'invention, le sens d'enroulement du ressort 30 est inversé par rapport au sens d'enroulement du filetage 25. Le filetage 25 est par exemple à pas standard à droite et le ressort 30 est enroulé à gauche.According to the first embodiment of the invention, the winding direction of the spring 30 is reversed relative to the winding direction of the thread 25. The thread 25 is, for example, at standard pitch on the right and the spring 30 is wound to left.

Comme on peut le voir sur les figures 2 à 4, le ressort présente une première extrémité 32 reçue dans un premier trou 34 ménagé à l'avant de la partie avant 26 de la première bague 20, à proximité de l'extrémité avant 33 de la partie avant 26. Les dimensions angulaires du premier trou 34 sont avantageusement choisies de manière à ce que la première extrémité 32 du ressort 30 soit maintenue sur la première bague par friction mais d'autres moyens de maintien de l'extrémité 32 sur la première bague 20 sont possibles. Le premier trou 34 peut être un trou borgne ou un trou traversant.As can be seen on the Figures 2 to 4 the spring has a first end 32 received in a first hole 34 formed in front of the front portion 26 of the first ring 20, near the front end 33 of the front portion 26. The angular dimensions of the first hole 34 are advantageously chosen so that the first end 32 of the spring 30 is held on the first ring by friction but other means for holding the end 32 on the first ring 20 are possible. The first hole 34 may be a blind hole or a through hole.

Le ressort 30 présente une deuxième extrémité 36 passant dans un deuxième trou 37 ménagé dans la paroi de la partie avant 26 à l'extrémité arrière de celle-ci, cette deuxième extrémité 36 étant reçue dans un trou 38 ménagé dans le bourrelet 28 de la deuxième bague 21. Les dimensions angulaires du deuxième trou 37 sont par exemple supérieures à celles du fil du ressort 30, de manière à ce que dernier passe avec un certain jeu latéral à travers le deuxième trou 37 et les dimensions angulaires du trou 38 sont avantageusement choisies de manière à ce que la deuxième extrémité 36 du ressort 30 soit maintenue sur la deuxième bague 21 par friction ou tout autre moyen. Comme représenté sur les figures, le deuxième trou 37 peut être disposé de manière à ce que le premier trou 34 soit longitudinalement disposé entre l'extrémité avant 33 de la partie avant 26 de la première bague 20 et le deuxième trou 37.The spring 30 has a second end 36 passing through a second hole 37 formed in the wall of the front portion 26 at the rear end thereof, this second end 36 being received in a hole 38 formed in the bead 28 of the second ring 21. The angular dimensions of the second hole 37 are for example greater than those of the spring wire 30, so that the last passes with a certain lateral clearance through the second hole 37 and the angular dimensions of the hole 38 are advantageously chosen so that the second end 36 of the spring 30 is held on the second ring 21 by friction or any other means. As shown in the figures, the second hole 37 may be arranged so that the first hole 34 is longitudinally disposed between the front end 33 of the front portion 26 of the first ring 20 and the second hole 37.

Le ressort 30 présente par exemple au repos un diamètre intérieur di inférieur à la plus grande dimension transversale Di de l'embase 3, ce diamètre intérieur di étant de façon classique calculé comme étant la différence entre le diamètre extérieur du ressort et le double du diamètre du fil du ressort.The spring 30 has for example at rest an inner diameter d i smaller than the largest transverse dimension D i of the base 3, this inner diameter d i being conventionally calculated as the difference between the outer diameter of the spring and the double the diameter of the spring wire.

On va maintenant décrire un exemple de connexion du corps 2 à l'embase 3 à l'aide du dispositif 4.We will now describe an example of connection of the body 2 to the base 3 with the aid of the device 4.

Lors d'une première étape, l'opérateur agit sur la partie de préhension 23 de la première bague 20 pour déplacer cette dernière en rotation selon le sens des aiguilles d'une montre. Du fait de cette opération, le diamètre intérieur di du ressort 30 augmente, permettant au ressort 30 d'être enfilé autour de la portion 14 de diamètre Di de l'embase 3. La distance angulaire sur laquelle s'étend le deuxième trou 37 dans la paroi de la première bague 20 est avantageusement supérieure ou égale à la rotation angulaire de la deuxième extrémité 36 du ressort 30 permettant d'amener le diamètre intérieur di du ressort 30 à une valeur supérieure à la plus grande dimension transversale Di de l'embase 3.In a first step, the operator acts on the gripping portion 23 of the first ring 20 to move the latter in rotation in the direction of clockwise. Due to this operation, the inner diameter d i of the spring 30 increases, allowing the spring 30 to be threaded around the portion 14 of diameter D i of the base 3. The angular distance on which extends the second hole 37 in the wall of the first ring 20 is advantageously greater than or equal to the angular rotation of the second end 36 of the spring 30 to bring the inner diameter d i of the spring 30 to a value greater than the largest transverse dimension D i of the base 3.

Lors de ce mouvement de rotation de la partie de préhension 23, les filetages 17 et 25 coopèrent, selon un système vis-écrou.During this rotational movement of the gripping portion 23, the threads 17 and 25 cooperate, in a screw-nut system.

A l'issue de cette étape, l'ensemble est tel que représenté aux figures 3 et 4, le ressort 30 étant alors précontraint contre la surface extérieure de la portion tubulaire 14 de l'embase 3 du fait des caractéristiques du ressort. L'extrémité avant 15 de la partie 16 de l'embase 3 s'applique contre le joint annulaire 7, garantissant l'étanchéité de la connexion obtenue, et le maintien du corps 2 sur l'embase 3 est assuré par la coopération des filetages 17 et 25 et par le serrage exercé par le ressort 30 sur la portion 14 de l'embase 3.At the end of this stage, the whole is as represented in figures 3 and 4 , the spring 30 then being prestressed against the outer surface of the tubular portion 14 of the base 3 because of the characteristics of the spring. The front end 15 of the portion 16 of the base 3 is applied against the annular seal 7, ensuring the sealing of the connection obtained, and the maintenance of the body 2 on the base 3 is provided by the cooperation of the threads 17 and 25 and by the tightening exerted by the spring 30 on the portion 14 of the base 3.

Si un opérateur souhaite déconnecter le corps 2 de l'embase 3, il ne peut faire tourner la première bague 20 dans le sens inverse des aiguilles d'une montre, cette rotation ayant pour effet de diminuer le diamètre intérieur di du ressort 30 et tendant à serrer davantage le ressort 30 contre la portion 14 de l'embase 3. Ainsi, une telle action, au lieu de permettre la libération du corps par rapport à l'embase, tend à serrer encore davantage ces deux éléments.If an operator wishes to disconnect the body 2 from the base 3, he can not rotate the first ring 20 in the counterclockwise direction, this rotation having the effect of reducing the internal diameter d i of the spring 30 and tending to further tighten the spring 30 against the portion 14 of the base 3. Thus, such action, instead of allowing the release of the body relative to the base, tends to tighten further these two elements.

Pour desserrer le ressort 30, l'opérateur peut faire tourner en rotation la deuxième bague 21 via le bourrelet 28 dans le sens inverse des aiguilles d'une montre, augmentant ainsi le diamètre intérieur di du ressort 30, ce qui permet la rotation de l'extrémité 36 du ressort dans le deuxième trou 37, permettant le déplacement du ressort 30 par rapport à la portion tubulaire 14 et, en conséquence, la déconnexion du corps 2 de l'embase 3.To loosen the spring 30, the operator can rotate the second ring 21 via the bead 28 counterclockwise, thereby increasing the inner diameter d i of the spring 30, which allows the rotation of the spring 30. the end 36 of the spring in the second hole 37, allowing the displacement of the spring 30 relative to the tubular portion 14 and, consequently, the disconnection of the body 2 from the base 3.

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

Selon un deuxième mode de réalisation non représenté, le sens d'enroulement du ressort 30 est le même que le sens d'enroulement du filetage 25, par exemple à gauche ou à droite. Le premier trou 34 est alors ménagé dans la paroi de la première bague 20 à distance de l'extrémité avant 33 de la partie avant 26 de la première bague 20 tandis que le deuxième trou 37 et le trou 38 sont disposés longitudinalement à proximité de l'extrémité avant 33. Selon ce deuxième mode de réalisation, le deuxième trou 37 est disposé longitudinalement entre l'extrémité avant 33 et le premier trou 34.According to a second embodiment not shown, the winding direction of the spring 30 is the same as the winding direction of the thread 25, for example left or right. The first hole 34 is then formed in the wall of the first ring 20 at a distance from the front end 33 of the front portion 26 of the first ring 20 while the second hole 37 and the hole 38 are arranged longitudinally close to the front end 33. According to this second embodiment, the second hole 37 is disposed longitudinally between the front end 33 and the first hole 34.

La distance angulaire sur laquelle s'étend le premier trou 34 dans la paroi de la première bague 20 est alors avantageusement supérieure ou égale à la rotation angulaire de la deuxième extrémité 36 du ressort 30 permettant d'amener le diamètre intérieur di du ressort 30 à une valeur supérieure à la plus grande dimension transversale Di de l'embase 3 et les dimensions angulaires du deuxième trou 37 sont avantageusement choisies de manière à ce que la première extrémité 32 du ressort 30 soit maintenue sur la première bague par friction mais d'autres moyens de maintien de l'extrémité 32 sur la première bague 20 sont possibles.The angular distance over which the first hole 34 extends in the wall of the first ring 20 is then advantageously greater than or equal to the angular rotation of the second end 36 of the spring 30 making it possible to bring the inside diameter d i of the spring 30 to a value greater than the largest transverse dimension D i of the base 3 and the angular dimensions of the second hole 37 are advantageously chosen so that the first end 32 of the spring 30 is held on the first ring by friction but other means for holding the end 32 on the first ring 20 are possible.

La figure 5 représente une variante du deuxième mode de réalisation qui vient d'être décrit. Dans l'exemple de la figure 5, le filetage 25 est porté par le ressort 30, étant formé sur le surface intérieure 50 du ressort 30. Le filetage 25, qui est dans l'exemple considéré enroulé dans le même sens que le ressort 30, est configuré pour coopérer avec le filetage 17 porté par le deuxième élément de connecteur 3. Comme on peut le voir en comparant les figures 3 et 5, le fait de réaliser le filetage 25 au niveau du ressort 30 permet de réduire la longueur de la première pièce 20.The figure 5 represents a variant of the second embodiment which has just been described. In the example of the figure 5 , the thread 25 is carried by the spring 30, being formed on the inner surface 50 of the spring 30. The thread 25, which is in the example considered wound in the same direction as the spring 30, is configured to cooperate with the threading 17 worn by the second connector element 3. As can be seen by comparing the figures 3 and 5 , making the thread 25 at the spring 30 reduces the length of the first piece 20.

En outre, dans l'exemple de la figure 5, la portion filetée 17 du deuxième élément de connecteur 3 est formée sur la surface extérieure de la portion 14 de diamètre Di.In addition, in the example of figure 5 , the threaded portion 17 of the second connector element 3 is formed on the outer surface of the portion 14 of diameter D i .

Le poids total du dispositif 4 et du premier élément de connecteur 2 peut être intérieur à 10g.
Le diamètre intérieur du ressort 30 au repos est dans l'exemple de la figure 5 configuré pour exercer une friction sur la portion filetée 17 complémentaire.The total weight of the device 4 and the first connector element 2 may be internal to 10 g.
The inner diameter of the spring 30 at rest is in the example of the figure 5 configured to exert friction on the complementary threaded portion 17.

L'invention n'est par exemple pas limitée à un dispositif pour la connexion de deux éléments de connecteur coaxiaux, s'appliquant par exemple aussi à des éléments de connecteur multicontact.The invention is for example not limited to a device for connecting two coaxial connector elements, for example also applying to multicontact connector elements.
