Description

La présente invention concerne des perfectionnements apportés aux connecteurs notamment aux connecteurs électriques, munis d'une bague d'accouplement et de verrouillage, et plus particulièrement aux connecteurs électriques, constitués de deux éléments de connecteur accouplables mécaniquement l'un à l'autre pour établir des liaisons entre des organes respectifs contenus dans ces deux éléments de connecteur, les deux éléments de connecteur étant pourvus d'un boîtier et l'un de ces boîtiers supportant une bague d'accouplement mécanique et de verrouillage mécanique dudit accouplement apte à coopérer avec le boîtier de l'autre élément, ladite bague étant composée d'une bague intérieure agencée en vue de réaliser l'accouplement ou le désaccouplement mécanique avec l'autre élément et une bague extérieure agencée pour commander le verrouillage ou le déverrouillage mécanique de l'accouplement des deux éléments, les deux bagues étant solidaires l'une de l'autre en rotation et la bague extérieure pouvant coulisser axialement par rapport à la bague intérieure.The present invention relates to improvements made to connectors, in particular to electrical connectors, provided with a coupling and locking ring, and more particularly to electrical connectors, consisting of two connector elements which can be mechanically coupled together to establish connections between respective members contained in these two connector elements, the two connector elements being provided with a housing and one of these housings supporting a mechanical coupling ring and mechanical locking of said coupling capable of cooperating with the housing of the other element, said ring being composed of an inner ring arranged to effect mechanical coupling or uncoupling with the other element and an outer ring arranged to control the mechanical locking or unlocking of the coupling of the two elements, the two rings being integral with one another in rotation and the outer ring able to slide axially relative to the inner ring.

Il doit être précisé dès à présent que, bien que l'on se réfère ici spécifiquement à des connecteurs élec- triques -car c'est dans cette application que l'invention semble devoir présenter le plus grand intérêt-, il n'est pas exclu que l'invention puisse trouver application également dans d'autres types de connecteurs,tels que par exemple les connecteurs optiques (connecteurs électrooptiques, connecteurs pour fibres optiques, etc.), qui peuvent utiliser des boîtiers analogues ou identiques à ceux des connecteurs électriques.It should be made clear right now that, although we are referring here specifically to electrical connectors - trikes - because it is in this application that the invention seems to have the greatest interest -, it is not excluded that the invention can also find application in other types of connectors, such as for example optical connectors (electrooptical connectors, connectors for optical fibers, etc.), which can use housings similar or identical to those of electrical connectors .

Dans les connecteurs du genre précité, la bague d'accouplement est habituellement libre lorsque les deux éléments de connecteur ne sont pas accouplés l'un à l'autre. Il est ainsi tout-à-fait possible que cette bague soit manipulée à vide ; en particulier, il est possible de faire passer la bague dans la position qu'elle doit occuper pour verrouiller mécaniquement l'accouplement des deux éléments de connecteur. Dans cette position de verrouillage, des organes de verrouillage tels que des doigts, des billes ou analogues sont amenés en situation saillante et, si un accouplement entre deux éléments de connecteur est tenté alors que la bague se trouve dans ladite position de verrouillage, les deux éléments de connecteur risquent d'être détériorés.In connectors of the aforementioned type, the coupling ring is usually free when the two connector elements are not coupled to each other. It is thus entirely possible for this ring to be handled empty; in particular, it is possible to pass the ring into the position it must occupy to mechanically lock the coupling of the two connector elements. In this locking position, locking members such as fingers, balls or the like are brought into a projecting position and, if a coupling between two connector elements is attempted while the ring is in said locking position, both connector elements may be damaged.

L'invention a donc essentiellement pour but de remédier à cet inconvénient afin de sauvegarder l'intégrité du connecteur et, sans rien modifier aux diverses fonctions essentielles assurées classiquement par la bague d'accouplement et de verrouillage (accouplement mécanique des deux éléments de connecteur, verrouillage mécanique de cet accouplement, éventuellement confirmation mécanique de ce verrouillage), d'ajouter une sécurité supplémentaire assurant la retenue de la bague dans sa position de désaccouplement lorsque les deux éléments de connecteur ne sont pas accouplés l'un à l'autre, cette sécurité devant pouvoir s'effacer de façon rapide et automatique lors de l'accouplement, bien entendu sans qu'il en résulte un coût et une complexité supplémentaires du connecteur.The invention therefore essentially aims to remedy this drawback in order to save the integrity of the connector and, without modifying anything to the various essential functions conventionally provided by the coupling and locking ring (mechanical coupling of the two connector elements, mechanical locking of this coupling, possibly mechanical confirmation of this locking), to add an additional security ensuring the retention of the ring in its uncoupling position when the two connector elements are not coupled to each other, this security must be able to be erased quickly and automatically during coupling, of course without this resulting in additional cost and complexity of the connector.

A ces fins, un connecteur agencé conformément à l'invention se caractérise en ce que sont en outre prévus des moyens de blocage relâchables associés à la susdite bague et agencés de manière à pouvoir occuper deux positions fonctionnelles,savoir une première position ou position de blocage dans laquelle les moyens de blocage solidarisent l'une à l'autre les bagues intérieure et extérieure et interdisent l'actionnement de la seule bague extérieure pour la faire passer dans la position correspondant au verrouillage mécanique tant que les éléments de connecteur ne sont pas accouplés mécaniquement l'un à l'autre, et une seconde position, ou position de libération, pour laquelle, sous l'action de moyens de commande qui sont inhibés tant que les deux éléments de connecteur ne sont pas accouplés l'un à l'autre, les moyens de blocage libèrent la bague extérieure et l'autorisent à passer dans sa position de verrouillage de l'accouplement des deux éléments de connecteur.For these purposes, a connector arranged in accordance with the invention is characterized in that there are further provided releasable blocking means associated with the aforesaid ring and arranged so as to be able to occupy two functional positions, namely a first position or blocking position. in which the locking means fasten the inner and outer rings to each other and prohibit actuation of the single outer ring so as to pass it into the position corresponding to mechanical locking as long as the connector elements are not coupled mechanically to each other, and a second position, or release position, for which, under the action of means of communication which are inhibited as long as the two connector elements are not coupled to each other, the locking means release the outer ring and allow it to pass into its locked position for coupling the two elements of connector.

De préférence, les moyens de blocage comprennent un organe mobile déplaçable radialement appartenant à l'une des bagues intérieure ou extérieur et un logement, appartenant à l'une des bagues respectivement extérieure ou intérieure, avec lequel est apte à coopérer le susdit organe mobile.Preferably, the locking means comprise a movable radially movable member belonging to one of the inner or outer rings and a housing, belonging to one of the respectively outer or inner rings, with which is able to cooperate with the aforesaid movable member.

Avantageusement, les moyens de commande des moyens de blocage sont constitués par une partie du boîtier de l'élément de connecteur qui, dans la position accouplée des deuX éléments est engagée dans l'élément de connecteur et est apte à coopérer fonctionnellement avec une partie correspondante des moyens de blocageAdvantageously, the means for controlling the blocking means consist of a part of the housing of the connector element which, in the coupled position of the two elements, is engaged in the connector element and is capable of cooperating functionally with a corresponding part. blocking means

Lorsque les deux dernières dispositions ci-dessus énumérées sont réunies, il peut être souhaitable que l'organe mobile radialement comprenne un jonc annulaire élastiquement déformable entre une première position dans laquelle il est logé, dans une gorge annulaire creusée dans la bague intérieure en faisant saillie partiellement hors de celle-ci et en s'engageant partiellement dans une seconde gorge creusée dans la bague extérieure (position de blocage de la bague extérieure) et une position où il est totalement effacé dans la seconde gorge (position de libération de la bague extérieure) et les moyens de commande comprennent au moins une saillie radiale, associée audit jonc, engagée sur le passage de la partie susmentionnée du boîtier de l'élément de connecteur lorsque le jonc est dans sa première position (position de blocage).When the last two arrangements listed above are combined, it may be desirable for the radially movable member to comprise an elastically deformable annular rod between a first position in which it is housed, in an annular groove hollowed out in the inner ring projecting partially out of it and partially engaging in a second groove hollowed out in the outer ring (blocking position of the outer ring) and a position where it is completely erased in the second groove (position in which the outer ring is released ) and the control means comprise at least one radial projection, associated with said rod, engaged on the passage of the aforementioned part of the housing of the connector element when the rod is in its first position (blocking position).

De façon intéressante, la partie susmentionnée du boîtier de l'élément de connecteur est constituée par le bord ou une zone du bord antérieur dudit boîtier.Interestingly, the aforementioned part of the housing of the connector element is formed by the edge or an area of the front edge of said housing.

Avantageusement, dans ce cas, la saillie radiale associée au jonc est une bille retenue dans un logement délimité d'un côté par une cavité creusée dans le corps de la bague intérieure et de l'autre côté par une cavité creusée dans le jonc.Advantageously, in this case, the radial projection associated with the rod is a ball retained in a housing delimited on one side by a cavity dug in the body of the inner ring and on the other side by a cavity dug in the rod.

Lorsque le connecteur comporte en outre des moyens de confirmation du verrouillage de la bague d'accouplement dans sa position d'accouplement verrouillée, il peut être intéressant, pour simplifier la structure, le coût et le mode de manipulation du connecteur, de combiner lesdits moyens de confirmation du verrouillage et les moyens de retenue de la bague conformes à l'invention ; dans ce but, on prévoit, dans le cas de la dernière disposition mentionnée plus haut, que le jonc comporte une seconde cavité voisine axialement de la première et séparée de celle-ci par une protubérance possédant deux rampes opposées.When the connector further comprises means for confirming the locking of the coupling ring in its locked coupling position, it may be advantageous, to simplify the structure, the cost and the method of handling the connector, to combine said means confirming the locking and the ring retaining means according to the invention; for this purpose, provision is made, in the case of the last arrangement mentioned above, that the rod comprises a second cavity adjacent axially to the first and separated from the latter by a protuberance having two opposite ramps.

L'invention sera mieux comprise à la lecture de la description détaillée qui suit d'un mode de réalisation préféré donné uniquement à titre illustratif sans aucun caractère limitatif ; dans cette description on se réfère aux dessins annexés sur lesquels les figures 1 à 4 représentent, de façon schématique et partielle, un connecteur agencé conformément à l'invention vu, en demi-coupe diamétrale, respectivement dans quatre positions fonctionnelles différentes.The invention will be better understood on reading the following detailed description of a preferred embodiment given solely by way of illustration without any limiting character; in this description, reference is made to the appended drawings in which FIGS. 1 to 4 show, schematically and partially, a connector arranged in accordance with the invention seen, in diametrical half-section, respectively in four different functional positions.

Sur les figures, seuls ont été représentés les boîtiers des deux éléments constitutifs du connecteur. Les organes renfermés par ces boîtiers (corps isolants et contacts électriques portés par ceux-ci dans le cas de connecteurs électriques ; organes opto-électroniques ou fibres optiques dans le cas de connecteurs optiques, notamment) n'ont pas été représentés, pour alléger les dessins, car n'entrant pas dans le domaine de l'invention.In the figures, only the boxes of the two components of the connector have been shown. The bodies enclosed by these boxes (insulating bodies and electrical contacts carried by them in the case of electrical connectors; opto-electronic bodies or optical fibers in the case of optical connectors, in particular) have not been shown, in order to alleviate the drawings, because not falling within the scope of the invention.

En se référant tout d'abord à la figure 1, le connecteur est constitué de deux éléments A et B accouplables mécaniquement l'un à l'autre pour assurer des liaisons entre des organes (non représentés) qu'ils renferment respectivement.Referring first to Figure 1, the connector consists of two elements A and B accou mechanically pliable to each other to ensure connections between members (not shown) which they contain respectively.

L'élément de connecteur A (à gauche sur les dessins) est ici supposé être un élément fixe agencé pour être monté sur un support. Son boîtier 1, de forme générale sensiblement tubulaire, est donc muni de moyens de fixation (collerette de butée 2, filetage 3, écrou de serrage 4) pour son maintien dans un orifice 5 d'un support 6.The connector element A (on the left in the drawings) is here assumed to be a fixed element arranged to be mounted on a support. Its housing 1, of generally substantially tubular shape, is therefore provided with fixing means (stop collar 2, thread 3, tightening nut 4) for its retention in an orifice 5 of a support 6.

A l'extrémité antérieure du boîtier 1 (c'est-à-dire l'extrémité tournée vers l'autre élément B et par laquelle s'effectue la coopération mécanique de l'élément A avec l'élément B),il est prévu sur la surface externe du boîtier 1, un filetage 7 ainsi qu'une gorge annulaire 8 (ou une pluralité de cavités réparties circonférentiellement) située en arrière du filetage 7. En outre, la surface externe du boîtier 1, au voisinage du bord antérieur, est chanfreinée pour constituer une rampe annulaire 9.At the front end of the housing 1 (that is to say the end facing the other element B and through which the mechanical cooperation of the element A with the element B takes place), provision is made on the outer surface of the housing 1, a thread 7 as well as an annular groove 8 (or a plurality of cavities distributed circumferentially) situated behind the thread 7. In addition, the outer surface of the housing 1, in the vicinity of the front edge, is chamfered to form an annular ramp 9.

L'élément de connecteur B (à droite sur les dessins) est supposé être un élément mobile (dit "élément de connecteur sur table"), par exemple fixé à l'extrémité d'un câble. Son boîtier 10 est, lui aussi, de forme générale sensiblement tubulaire et son extrémité antérieure (tournée vers l'élément A) est agencée pour s'engager à l'intérieur du boîtier 1 de l'élément A. Autour du boîtier 10 est disposée, et retenue par des moyens habituels connus de l'homme de l'art une bague d'accouplement et de verrouillage 11, laquelle est elle-même constituée de deux bagues concentriques, une bague intérieure 12 et une bague extérieure 13.The connector element B (on the right in the drawings) is assumed to be a mobile element (called "connector element on table"), for example fixed to the end of a cable. Its housing 10 is also of generally substantially tubular shape and its anterior end (facing the element A) is arranged to engage inside the housing 1 of the element A. Around the housing 10 is arranged , and retained by usual means known to those skilled in the art, a coupling and locking ring 11, which itself is made up of two concentric rings, an inner ring 12 and an outer ring 13.

La face interne de la bague intérieure 12 est munie d'un filetage 14 et est située à une distance radiale du boîtier 10 suffisante pour laisser le passage à la partie antérieure du boîtier 1 de l'élémentA.The inner face of the inner ring 12 is provided with a thread 14 and is located at a radial distance from the housing 10 sufficient to allow passage to the front part of the housing 1 of the elementA.

En avant du filetage 14 sont prévus des trous 15, répartis circonférentiellement, traversant de part en part l'épaisseur de la bague intérieure 12 ; leur bord intérieur (tourné vers l'axe de l'élément de connecteur B) délimite une ouverture de diamètre sensiblement plus réduit que celui du reste du trou. Chaque trou renferme une bille 16 dont le diamètre est sensiblement supérieur à la hauteur du trou 15.In front of the thread 14 are provided holes 15, distributed circumferentially, passing right through the thickness of the inner ring 12; their inner edge (facing the axis of the connector element B) delimits an opening of diameter substantially smaller than that of the rest of the hole. Each hole contains a ball 16 whose diameter is substantially greater than the height of the hole 15.

Des trous 17, agencés de la même manière que les trous 15 et renfermant respectivement des billes 18, sont prévus dans la bague intérieure 12 en arrière du filetage 14. Dans la zone des trous 17, la bague intérieure 12 présente, sur sa surface externe, un évidement annulaire de diamètre réduit formant une gorge 19.Holes 17, arranged in the same manner as holes 15 and respectively containing balls 18, are provided in the inner ring 12 behind the thread 14. In the area of the holes 17, the inner ring 12 has, on its outer surface , an annular recess of reduced diameter forming a groove 19.

La bague extérieure 13 présente, sur sa face intérieure, un évidement annulaire de diamètre accru formant une gorge 20 située approximativement en regard de la gorge 19 de la bague intérieure 12.The outer ring 13 has, on its inner face, an annular recess of increased diameter forming a groove 20 located approximately opposite the groove 19 of the inner ring 12.

Un jonc annulaire 21 est logé dans la gorge 19 ; ce jonc est élastiquement déformable radialement et son épaisseur est supérieure à la profondeur de la gorge 19 de telle sorte que, lorsque les deux gorges 19 et 20 sont en vis-à-vis, il enserre la gorge 19 en s'engageant en partie dans la gorge 20. Par contre, la gorge 20 a une profondeur suffisante pour abriter complètement le jonc 21 lorsque celui-ci est dilaté.An annular ring 21 is housed in the groove 19; this rod is radially elastically deformable and its thickness is greater than the depth of the groove 19 so that, when the two grooves 19 and 20 are opposite, it encloses the groove 19 by partially engaging in the groove 20. On the other hand, the groove 20 has a sufficient depth to completely shelter the rod 21 when the latter is expanded.

En outre, la face intérieure (c'est-à-dire tournée vers l'axe de l'élément B de connecteur) du jonc 21 comporte une protubérance annulaire 22 raccordée par deux rampes opposées aux portions de surfaces annulaires situées de part et d'autre, ce qui délimite deux cavités annulaires 23 et 24 dans l'une desquelles sont engagées les billes 18.In addition, the inner face (that is to say facing the axis of the connector element B) of the rod 21 has an annular protuberance 22 connected by two ramps opposite the portions of annular surfaces located on either side 'other, which delimits two annular cavities 23 and 24 in one of which are engaged the balls 18.

Dans une région située approximativement en regard des billes 16 de la bague intérieure 12, la bague extérieure 13 (en fait dans l'exemple représenté il s'agit d'un manchon intérieur solidarisé à la bague 13) présente une zone axiale 25 entourant étroitement (mais librement) la surface externe de la bague intérieure 12 et une zone axiale 26 de diamètre accru, raccordées par une zone conique 27 formant rampe.In a region located approximately opposite the balls 16 of the inner ring 12, the outer ring 13 (in fact in the example shown it is an inner sleeve secured to the ring 13) has an axial zone 25 closely (but freely) surrounding the external surface of the inner ring 12 and an axial zone 26 of increased diameter, connected by a conical zone 27 forming a ramp.

Enfin, on notera que la bague intérieure 12 et la bague extérieure 13 sont solidaires l'une de l'autre en rotation (par exemple au moyen de canelures 28) mais qu'elles peuvent coulisser axialement l'une par rapport à l'autre sur une certaine distance délimitée par des butées axiales appropriées.Finally, it will be noted that the inner ring 12 and the outer ring 13 are integral with one another in rotation (for example by means of grooves 28) but that they can slide axially with respect to each other over a certain distance delimited by appropriate axial stops.

Le fonctionnement du connecteur qui vient d'être décrit est le suivant.The operation of the connector which has just been described is as follows.

A la figure 1, les deux éléments de connecteur A et B sont présentés l'un en face de l'autre, mais ne sont pas encore accouplés. La bague d'accouplement 11 est dans son état d'attente d'accouplement, les deux bagues intérieure 12 et extérieure 13 en regard axialement l'une de l'autre : les zones 26 sont en regard des billes 16, autorisant celles-ci à s'effacer ; le jonc 21 est resserré dans la gorge 19 de la bague intérieure 12 et est engagé partiellement dans la gorge 20 de la bague extérieure 13, solidarisant ainsi axialement les deux bagues 12 et 13 et empêchant la bague 13 d'être déplacée vers l'arrière (correspondant à la position de verrouillage d'accouplement de la bague 11 comme cela sera indiqué plus loin).In FIG. 1, the two connector elements A and B are presented opposite one another, but are not yet coupled. The coupling ring 11 is in its waiting state for coupling, the two inner 12 and outer 13 rings facing axially from one another: the zones 26 are facing the balls 16, authorizing the latter to fade; the ring 21 is tightened in the groove 19 of the inner ring 12 and is partially engaged in the groove 20 of the outer ring 13, thus axially securing the two rings 12 and 13 and preventing the ring 13 from being moved backwards (corresponding to the coupling locking position of the ring 11 as will be indicated below).

Dans cette même position du jonc 21, les billes 18 sont engagées dans la cavité 24 située vers l'arrière de l'élément de connecteur B, matérialisant ainsi la situation de la bague 11 dans sa position accouplement - désaccouplement mécaniques.In this same position of the rod 21, the balls 18 are engaged in the cavity 24 located towards the rear of the connector element B, thus materializing the situation of the ring 11 in its coupling - mechanical uncoupling position.

A la figure 2, les deux éléments A et B sont représentés en cours d'accouplement mécanique. La partie antérieure du boîtier 1 de l'élément A entoure la partie antérieure du boîtier 10 de l'élément B et le rapprochement progressif des deux éléments A et B est obtenu grâce au vissage effectué par rotation de la bague 11 et coopération des filetages 7 et 14. Les billes 16 ont été écartées par la rampe annulaire 9. Les autres parties des éléments A et B restent dans le même état que précédemment.In Figure 2, the two elements A and B are shown during mechanical coupling. The front part of the housing 1 of the element A surrounds the front part of the housing 10 of the element B and the approximation progressive of the two elements A and B is obtained by screwing performed by rotation of the ring 11 and cooperation of the threads 7 and 14. The balls 16 have been separated by the annular ramp 9. The other parts of the elements A and B remain in the same condition as before.

A la figure 3, les deux éléments de connecteur A et B sont montrés en position complètement accouplée (mais non verrouillée). La partie antérieure du boîtier 1 de l'élément A est enfoncée au maximum sur le boîtier 10 de l'élément B et la rampe annulaire 9 a repoussé radialement vers l'extérieur les billes 18, ce qui a dilaté radialement le jonc 21. Celui-ci est maintenant complètement effacé dans la gorge 20 de la bague extérieure 13, ce qui a pour effet de libérer axialement la bague extérieure 13 de la bague intérieure 12.In FIG. 3, the two connector elements A and B are shown in the fully coupled (but not locked) position. The front part of the housing 1 of the element A is pushed in as much as possible on the housing 10 of the element B and the annular ramp 9 has pushed the balls 18 radially outwards, which has radially expanded the rod 21. That this is now completely erased in the groove 20 of the outer ring 13, which has the effect of axially releasing the outer ring 13 from the inner ring 12.

Enfin, la figure 4 montre les deux éléments de connecteur A et B en position accouplée, avec verrouillage mécanique de l'accouplement et confirmation mécanique du verrouillage. La bague extérieure 13, libérée comme indiqué plus haut, est tirée axialement vers l'arrière de l'élément B.Finally, FIG. 4 shows the two connector elements A and B in the coupled position, with mechanical locking of the coupling and mechanical confirmation of the locking. The outer ring 13, released as indicated above, is pulled axially towards the rear of the element B.

Au cours de ce mouvement, les billes 16 repoussées par la rampe annulaire 27, sont bloquées par la zone annulaire 25 en position saillante dans laquelle elles sortent partiellement des trous 15 et s'engagent dans la gorge annulaire 8 du boîtier 1 et l'élément A. Tout déplacement axial de la bague intérieure 12 (par rotation de l'ensemble de la bague 11) est ainsi empêché et les deux éléments A et B sont verrouillés en position connectée.During this movement, the balls 16 pushed back by the annular ramp 27, are blocked by the annular zone 25 in the projecting position in which they partially leave the holes 15 and engage in the annular groove 8 of the housing 1 and the element A. Any axial movement of the inner ring 12 (by rotation of the assembly of the ring 11) is thus prevented and the two elements A and B are locked in the connected position.

Simultanément, au cours du déplacement de la bague extérieure 13, le jonc 21 a été entraîné par celle-ci et, après déformation élastique radiale du jonc au passage de la protubérance 22 sur les billes 18, c'est maintenant la plage annulaire 23 qui est en appui contre les billes 18. Ainsi retenue par le jonc 21, la bague extérieure 13 ne peut plus revenir intempestivement vers l'avant de l'élément B, tant qu'elle ne reçoit pas un effort axial approprié supérieur à l'effort de déformation élastique du jonc 21.Simultaneously, during the movement of the outer ring 13, the ring 21 has been driven by it and, after radial elastic deformation of the ring when the protuberance 22 passes over the balls 18, it is now the annular area 23 which is pressed against the balls 18. Thus retained by the ring 21, the outer ring 13 can no longer inadvertently return towards the front of the element B, as long as it does not receive an appropriate axial force greater than the elastic deformation force of the rod 21.

Le déverrouillage et le désaccouplement des éléments A et B s'effectuent par les opérations inverses aux précédentes.The unlocking and uncoupling of elements A and B is carried out by the reverse operations to the previous ones.

Comme il va de soi et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus spécialement envisagés ; elle en embrasse, au contraire, toutes les variantes.As goes without saying and as it already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more especially envisaged; on the contrary, it embraces all its variants.
