Description

La présente invention concerne le domaine de la connectique, en particulier des connexions par cordon, câble ou élément similaire de raccordement, et a pour objet un connecteur électrique muni d'un blocage en rotation, préférentiellement amovible, et un cordon de raccordement comprenant au moins un tel connecteur.The present invention relates to the field of connectors, in particular connections by cord, cable or the like connection, and relates to an electrical connector provided with a blocking in rotation, preferably removable, and a connection cord comprising at least one such connector.

La présente invention est relative à un connecteur électrique, mâle ou femelle, du type comportant un corps tubulaire en un matériau isolant, portant les bornes de connexion mâles ou femelles, et un manchon cylindrique monté avec faculté de rotation sur la face externe dudit corps tubulaire.The present invention relates to an electrical connector, male or female, of the type comprising a tubular body of a material insulator, carrying male or female connection terminals, and a sleeve cylindrical mounted with faculty of rotation on the external face of said body tubular.

Généralement, ce manchon cylindrique est bloqué en translation sur ledit corps tubulaire.Generally, this cylindrical sleeve is locked in translation on said tubular body.

Néanmoins, pour les connecteurs de ce type, il est dans certains cas nécessaire de pouvoir également bloquer ce manchon en rotation, notamment lorsque ce dernier réalise le ou contribue au raccordement du connecteur considéré avec un site de branchement adapté ou un connecteur complémentaire et que le verrouillage dudit raccordement est lié à une rotation et/ou à un blocage en rotation dudit manchon.However, for connectors of this type, it is in some cases case necessary to be able to also block this sleeve in rotation, especially when the latter performs or contributes to the connection of the connector considered with a suitable connection site or a connector and that the locking of said connection is linked to a rotation and / or a rotation lock of said sleeve.

Tel est notamment le cas, lorsque ledit manchon participe à une liaison par baïonnettes, à une liaison par vissage, à une liaison par enclenchement élastique, ou encore à une liaison par coopération de formes complémentaires, associée à une position en rotation spécifique dudit manchon.This is particularly the case, when said sleeve participates in a bayonet link, screw connection, link elastic engagement, or to a connection by cooperation of shapes complementary, associated with a specific rotational position of said muff.

Le problème posé à la présente invention consiste donc à fournir à un connecteur du type précité un moyen simple et efficace pour le verrouillage, éventuellement amovible, en rotation du manchon cylindrique.The problem posed by the present invention therefore consists in provide a connector of the aforementioned type with a simple and effective means for locking, possibly removable, in rotation of the cylindrical sleeve.

A cet effet, la présente invention a pour objet un connecteur du type précité, caractérisé en ce qu'il comprend en outre une pièce en forme de bague, également montée sur la face externe dudit corps tubulaire avec faculté de translation relative par rapport à ce dernier et en étant solidaire en rotation de ce dernier, ladite pièce étant pourvue de moyens d'engagement et pouvant être déplacée par coulissement dans une position de verrouillage dans laquelle ces moyens d'engagement viennent en prise avec des moyens d'engagement complémentaires du manchon cylindrique, de manière à rendre ce dernier également solidaire en rotation dudit corps tubulaire par l'intermédiaire de ladite pièce.To this end, the present invention relates to a connector of the aforementioned type, characterized in that it further comprises a shaped part ring, also mounted on the external face of said tubular body with faculty of relative translation with respect to the latter and being integral in rotation of the latter, said part being provided with engagement means and can be moved by sliding in a locked position in which these means of engagement engage with means complementary engagement of the cylindrical sleeve, so that making the latter also integral in rotation with said tubular body by through said room.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels :

  • La figure 1A est une vue en élévation latérale d'un connecteur selon un premier mode de réalisation de l'invention sur laquelle le manchon cylindrique n'est pas bloqué en rotation, et les figures 1B, 1C et 1D sont respectivement des vues en coupe selon A-A, B-B- et C-C du connecteur de la figure 1A ;
  • La figure 2A est une vue en élévation latérale du connecteur des figures 1 sur laquelle le manchon cylindrique est bloqué en rotation, et les figures 2B, 2C et 2D sont respectivement des vues en coupe selon A-A, B-B et C-C du connecteur de la figure 2A ;
  • La figure 3 est une vue éclatée en perspective du connecteur représenté sur les figures 1 et 2 et correspondant à un connecteur avec une interface de connexion mécanique mâle, et,
  • La figure 4 est une vue éclatée en perspective, similaire à celle de la figure 3, d'un connecteur selon un second mode de réalisation de l'invention, correspondant à un connecteur avec une extrémité ou interface de connexion mécanique femelle.
    • The invention will be better understood from the following description, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which:
  • FIG. 1A is a side elevation view of a connector according to a first embodiment of the invention in which the cylindrical sleeve is not locked in rotation, and FIGS. 1B, 1C and 1D are respectively sectional views along AA, BB- and CC of the connector of Figure 1A;
  • FIG. 2A is a side elevation view of the connector of FIGS. 1 in which the cylindrical sleeve is locked in rotation, and FIGS. 2B, 2C and 2D are respectively sectional views along AA, BB and CC of the connector of FIG. 2A ;
  • FIG. 3 is an exploded perspective view of the connector shown in FIGS. 1 and 2 and corresponding to a connector with a male mechanical connection interface, and,
  • Figure 4 is an exploded perspective view, similar to that of Figure 3, of a connector according to a second embodiment of the invention, corresponding to a connector with an end or interface of female mechanical connection.

    • Comme le montrent les figures 1 à 4 des dessins annexés, le connecteur électrique 1 comporte un corps tubulaire 2 en un matériau isolant, portant les bornes de connexion mâles ou femelles, et un manchon cylindrique 3 monté avec faculté de rotation sur la face externe dudit corps tubulaire 2.As shown in Figures 1 to 4 of the accompanying drawings, the electrical connector 1 comprises a tubular body 2 made of a material insulator, carrying male or female connection terminals, and a sleeve cylindrical 3 mounted with faculty of rotation on the external face of said body tubular 2.

    Le corps tubulaire 2 comportera plusieurs sites de réception 12 des fils de liaison et des bornes de connexion.The tubular body 2 will include several reception sites 12 connecting wires and connection terminals.

    Conformément à l'invention, ce connecteur 1 comprend en outre une pièce 4 en forme de bague, également montée sur la face externe dudit corps tubulaire 2 avec faculté de translation relative par rapport à ce dernier et en étant solidaire en rotation de ce dernier, ladite pièce 4 étant pourvue de moyens d'engagement 5 et pouvant être déplacée par coulissement dans une position de verrouillage dans laquelle ces moyens d'engagement 5 viennent en prise avec des moyens d'engagement complémentaires 6 du manchon cylindrique 3, de manière à rendre ce dernier également solidaire en rotation dudit corps tubulaire 2 par l'intermédiaire de ladite pièce 4.According to the invention, this connector 1 comprises at in addition to a ring-shaped part 4, also mounted on the external face of said tubular body 2 with faculty of translation relative to this last and being integral in rotation with the latter, said part 4 being provided with engagement means 5 and capable of being moved by sliding in a locking position in which these means engagement 5 engage engagement means complementary 6 of the cylindrical sleeve 3, so as to make this the latter also integral in rotation with said tubular body 2 by through said part 4.

    Ainsi, le blocage en rotation du manchon 3 par rapport au corps 2 est obtenu par simple déplacement en translation limité de la pièce 4. Un déplacement en direction opposée de cette dernière à partir de sa position verrouillée ou de blocage en rotation, entraínera par conséquent une désolidarisation ou une libération en rotation dudit manchon 3 d'avec ledit corps 2.Thus, the locking in rotation of the sleeve 3 relative to the body 2 is obtained by simple displacement in limited translation of the part 4. A moving in the opposite direction of the latter from its position locked or locked in rotation, will therefore cause uncoupling or release in rotation of said sleeve 3 from said body 2.

    Comme le montrent notamment les figures 1A, 1B, 2A, 2B et 3, le connecteur 1 présente une structure sensiblement symétrique par rapport à son axe longitudinal X.As shown in particular in FIGS. 1A, 1B, 2A, 2B and 3, the connector 1 has a substantially symmetrical structure by relative to its longitudinal axis X.

    Selon une première caractéristique de l'invention, la liaison bloquée en rotation et libre en translation entre le corps tubulaire 2 et la pièce coulissante 4 formant bague intermédiaire de verrouillage en rotation est réalisée par au moins un ensemble coopérant [ergot(s) ou nervure(s) 7, 7' / rainure 8], dans lequel la rainure 8 s'étend dans la direction axiale du connecteur 1 et forme glissière pour ledit ou lesdits ergots ou nervures 7, 7', ledit au moins un(e) ergot ou nervure 7, 7' étant formé sur la paroi de l'un desdits corps tubulaire 2 et pièce coulissante 4, et la rainure 8 étant ménagée dans la paroi de l'autre desdits corps tubulaires 2 pièce coulissante 4.According to a first characteristic of the invention, the connection locked in rotation and free in translation between the tubular body 2 and the sliding part 4 forming intermediate ring for locking in rotation is produced by at least one cooperating assembly [lug (s) or rib (s) 7, 7 ′ / groove 8], in which the groove 8 extends in the axial direction of the connector 1 and slide shape for said lug (s) or ribs 7, 7 ′, said at least one lug or rib 7, 7 'being formed on the wall of one said tubular body 2 and sliding part 4, and the groove 8 being formed in the wall of the other of said tubular bodies 2 piece sliding 4.

    L'ergot ou les ergots 7, 7' ou la nervure 7 feront état d'une ou de base(s) à section suffisamment importante pour fournir une résistance au cisaillement correspondant à la force de blocage souhaitée.The lug or lugs 7, 7 ′ or the rib 7 will indicate one or more base (s) with sufficient cross-section to provide resistance to shear corresponding to the desired blocking force.

    De plus, l'ergot ou les ergots 7, 7' ou la nervure 7 sont avantageusement en contact surfacique avec le fond de la rainure 8 correspondante, en présentant par exemple tous les deux une section à forme rectangulaire en coupe transversale.In addition, the lug or lugs 7, 7 ′ or the rib 7 are advantageously in surface contact with the bottom of the groove 8 corresponding, for example both by presenting a section to rectangular shape in cross section.

    Conformément à une variante de réalisation préférentielle de l'invention, ledit connecteur 1 comprend au moins deux, préférentiellement quatre ensembles coopérants 7, 7' ; 8 répartis de manière équiangulaire autour de l'axe dudit connecteur 1.In accordance with a preferred embodiment variant of the invention, said connector 1 comprises at least two, preferably four cooperating sets 7, 7 '; 8 distributed equiangularly around the axis of said connector 1.

    De plus, chaque ensemble coopérant comprend au moins deux ergots 7 et 7' alignés axialement ou une nervure 7 à extension axiale, lesdits ergots 7 et 7' ou ladite nervure 7 étant formé(s) sur la face externe du corps tubulaire 2, les rainures 8 étant formées sur ou dans la face interne de la pièce coulissante 4 en forme de bague. In addition, each cooperating assembly includes at least two pins 7 and 7 'axially aligned or a rib 7 with axial extension, said lugs 7 and 7 ′ or said rib 7 being formed on the external face of the tubular body 2, the grooves 8 being formed on or in the internal face of the sliding part 4 in the form of a ring.

    Afin de pouvoir réaliser une discrimination aisée entre les positions verrouillée et déverrouillée (c'est-à-dire correspondant à une solidarisation, respectivement une désolidarisation, en rotation entre le corps 2 et le manchon 3) et de garantir un maintien de la position de verrouillage par enclenchement, la ou chaque rainure 8 comporte, au niveau de son fond, une protubérance 8' formant plot d'indexation dont le passage par-dessus un ergot 7 ou dans une découpe ou un renfoncement 7" de la nervure 7 de l'ensemble coopérant 7, 7' ; 8 concerné, lors du coulissement de la pièce coulissante 4 en forme de bague vers la position de verrouillage ou de blocage en rotation, correspond à l'établissement de la solidarisation en rotation du manchon cylindrique 3 avec le corps tubulaire 2, ledit ergot 7 ou ladite découpe 7" assurant également la rétention dudit plot 8' en position de verrouillage.In order to be able to easily discriminate between locked and unlocked positions (i.e. corresponding to a securing, respectively decoupling, in rotation between the body 2 and the sleeve 3) and to guarantee a maintenance of the position of interlocking, the or each groove 8 comprises, at the level from its bottom, a protrusion 8 'forming an indexing pad, the passage of which over a lug 7 or in a cutout or recess 7 "of the rib 7 of the cooperating assembly 7, 7 '; 8 concerned, when sliding from the sliding part 4 in the form of a ring towards the locking position or blocking in rotation, corresponds to the establishment of the joining in rotation of the cylindrical sleeve 3 with the tubular body 2, said lug 7 or said cut 7 "also ensuring the retention of said stud 8 'in locking position.

    Cette rétention pourra, en fonction de la conformation, des dimensions et/ou des matériaux de la protubérance 8' et de l'ergot ou de la nervure 7, être de nature permanente (inamovible) ou temporaire (amovible), cette dernière solution étant préférée et nécessitant une constructions desdits éléments 8' et 7 permettant un passage bidirectionnel du plot 8' par-dessus l'ergot 7 au niveau de chaque ensemble coopérant (flanc en pente et/ou arêtes arrondies).This retention may, depending on the conformation, dimensions and / or materials of the protrusion 8 ′ and of the lug or of the rib 7, be of a permanent (irremovable) or temporary nature (removable), the latter solution being preferred and requiring a constructions of said elements 8 ′ and 7 allowing bidirectional passage stud 8 'over lug 7 at each cooperating assembly (sloping side and / or rounded edges).

    Selon un mode de réalisation avantageux de l'invention, ressortant également des figures annexées, les moyens d'engagement 5 de la pièce coulissante 4 en forme de bague consistent en des crans radiaux, préférentiellement profilés dans la direction axiale du connecteur 1, formés sur la face externe ou interne de ladite pièce 4 et les moyens d'engagement complémentaires 6 du manchon cylindrique 3 consistent en une nervure circulaire, également pourvue ou constituée de crans radiaux ou réalisée en un matériau moins dur que celui formant les moyens d'engagement 5 de la pièce coulissante 4, ladite nervure 6 crantée ou non étant formée sur la face externe du manchon cylindrique 3 ou sur la face interne d'une portion annulaire 9 de plus grand diamètre dudit manchon cylindrique 3.According to an advantageous embodiment of the invention, Also emerging from the appended figures, the engagement means 5 of the sliding part 4 in the form of a ring consist of radial notches, preferably profiled in the axial direction of connector 1, formed on the external or internal face of said part 4 and the engagement means complementary 6 of the cylindrical sleeve 3 consist of a rib circular, also provided with or consisting of radial notches or made of a less hard material than that forming the engagement means 5 of the sliding part 4, said rib 6 notched or not being formed on the face external of the cylindrical sleeve 3 or on the internal face of a portion annular 9 of larger diameter of said cylindrical sleeve 3.

    En fonction de la solution retenue, les crans 5 viennent par conséquent en engagement par imbrication alternative ou engrènement avec les crans de la nervure 6, ou alors s'enfichent dans le matériau formant la nervure interne ou externe 6 de la portion annulaire 9, en assurant dans les deux cas une solidarisation en rotation de la pièce 4 avec le manchon 3. Depending on the solution chosen, the notches 5 come by consequent in engagement by alternative nesting or meshing with the notches of the rib 6, or else plug into the material forming the internal or external rib 6 of the annular portion 9, ensuring in the two cases a rotationally joining of the part 4 with the sleeve 3.

    Pour pouvoir avantageusement assurer le verrouillage ou blocage en rotation dans n'importe quelle position angulaire du manchon 3, les crans radiaux 5 sont présents, de manière continue, sur toute la périphérie extérieure ou intérieure de la pièce coulissante 4 en forme de bague et la nervure circulaire 6 formant les moyens d'engagement complémentaires est également fournie ou pourvue de crans, les ensembles coopérant 7, 7' / 8 présentant un jeu radial autorisant une rotation limitée du corps tubulaire 2 à la pièce coulissante 4 en forme de bague (les éléments 7, 7' pourront par exemple présenter une largeur moins importante que la largeur de la rainure 8).To be able to advantageously ensure locking or locking in rotation in any angular position of the sleeve 3, the radial notches 5 are present continuously over the entire outer or inner periphery of the sliding part 4 in the form of ring and the circular rib 6 forming the engagement means additional is also provided or provided with notches, the sets cooperating 7, 7 '/ 8 having a radial clearance allowing limited rotation of the tubular body 2 to the sliding part 4 in the form of a ring (the elements 7, 7 ′ may for example have a width that is less significant than the width of the groove 8).

    Il sera ainsi toujours possible d'aligner les deux moyens d'engagement crantés 5 et 6, de telle manière que les crans desdits deux moyens puissent s'engager mutuellement entre eux pour réaliser le blocage en rotation du manchon 3 avec la pièce 4.It will thus always be possible to align the two means notched engagement 5 and 6, so that the notches of said two means can engage each other to achieve blocking in rotation of the sleeve 3 with the part 4.

    Afin de garantir ou de forcer cet engagement ou imbrication mutuel(le) au moins au niveau de certains endroits périphériques, une partie de la nervure 7 ou et l'un des ergots 7' de chaque ensemble coopérant ergots 7, 7' / rainure 8 peut être disposé en regard de la nervure circulaire interne ou externe 6 du manchon cylindrique 3, de manière à forcer les crans radiaux 5 de la pièce coulissante 4 vers ladite nervure 6 crantée ou non ou vice versa (figure 4), et à garantir la venue en prise mutuelle des moyens d'engagement 5 et 6 en position verrouillée.In order to guarantee or force this engagement or nesting mutual at least at certain peripheral locations, some of the rib 7 or and one of the lugs 7 'of each assembly cooperating lugs 7, 7 '/ groove 8 can be arranged opposite the internal circular rib or external 6 of the cylindrical sleeve 3, so as to force the notches radials 5 of the sliding part 4 towards said rib 6 notched or not or vice versa (Figure 4), and to guarantee the mutual engagement of the means 5 and 6 in the locked position.
