Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne une bague de verrouillage. Elle s'applique, en particulier, à une bague de verrouillage, de type baïonnette d'un connecteur électrique circulaire, qui se trouve être la plus complexe à produire.The present invention relates to a locking ring. It applies, in particular, to a bayonet type locking ring of a circular electrical connector, which is found to be the most complex to produce.

ETAT DE LA TECHNIQUESTATE OF THE ART

La totalité des bagues de verrouillage à baïonnette sont de type monobloc ; c'est-à-dire qu'elles sont soient moulées, soient usinées en une seule pièce.All bayonet locking rings are monobloc type; that is, they are either molded or machined in one piece.

Dans les deux cas, les moyens à mettre en oeuvre sont complexes et coûteux, puisqu'il faut réaliser les rampes du système de verrouillage qui se situent à l'intérieur de la pièce, et sont ainsi en contre-dépouille.In both cases, the means to implement are complex and expensive, since it is necessary to realize the ramps of the locking system which are located inside the room, and are thus undercut.

La figure 1 montre le cas d'une pièce moulée 20 avec des rampes 21. Le moule doit être à noyau « éclipsable » afin de démouler les rampes.The figure 1 shows the case of a molded part 20 with ramps 21. The mold must be core "eclipsable" to unmold the ramps.

La complexité du moule ne permet pas, ou difficilement, de mouler une pièce optimisée en raison des contraintes d'injection, de la masse réduite à certains endroits et des épaisseurs constantes.The complexity of the mold does not allow or difficult to mold an optimized part due to injection constraints, the reduced mass in certain places and constant thicknesses.

Les figures 2 et 3 montrent une bague de verrouillage usinée en laiton. Les rampes taillées dans le diamètre intérieur de la bague, doivent être réalisées à l'aide de machines d'usinage (combinaison de mouvement, donc cames ou commande numérique), et de porte-outils (renvoi d'angle). Les zones 22 montrent les formes spécifiques à réaliser par l'intérieur. Ces opérations sont complexes et coûteuses et peuvent créer des rebuts.The figures 2 and 3 show a machined brass locking ring. The ramps cut in the internal diameter of the ring, must be made using machining machines (combination of movement, so cams or numerical control), and tool holders (bevel gear). Zones 22 show the specific shapes to be made by the interior. These operations are complex and expensive and can create scrap.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'invention vise à remédier à ces inconvénients.The invention aims to remedy these drawbacks.

A cet effet, l'invention concerne une bague de verrouillage, de type baïonnette, d'un connecteur électrique circulaire, caractérisée en ce qu'elle comporte :

  • une première pièce en forme d'anneau cylindrique s'étendant d'une extrémité à une autre, ladite première pièce comprend des encoches réparties sur la face interne de la première pièce adjacente à une extrémité et une première partie de rampe sur la face interne de la première pièce, la première pièce est en matière thermoplastique,
  • une deuxième pièce en forme d'anneau cylindrique, ladite deuxième pièce comprend des encoches réparties sur sa face externe et une deuxième partie de rampe sur la surface cylindrique interne et lorsque la première pièce et la deuxième pièce sont assemblées :
    • les encoches de la deuxième pièce s'emboitent dans les encoches de la première partie bloquant la mobilité en rotation de la deuxième partie par rapport à la première partie, et
    • la deuxième partie de rampe de la deuxième pièce forme le complément de la première partie de rampe de la première pièce.
To this end, the invention relates to a locking ring, bayonet type, a circular electrical connector, characterized in that it comprises:
  • a first cylindrical ring-shaped piece extending from one end to another, said first piece comprises notches distributed on the inner face of the first piece adjacent to one end and a first part of the ramp on the inner face of the first piece, the first piece is made of thermoplastic material,
  • a second piece in the form of a cylindrical ring, said second piece comprises notches distributed on its outer face and a second ramp part on the inner cylindrical surface and when the first piece and the second piece are assembled:
    • the notches of the second part fit into the notches of the first part blocking the rotational mobility of the second part relative to the first part, and
    • the second ramp portion of the second piece forms the complement of the first ramp portion of the first piece.

Une rampe présente une largeur donnée permettant un déplacement et un guidage d'un ergot du connecteur électrique pour son verrouillage.A ramp has a given width for moving and guiding a pin of the electrical connector for locking.

La bague de verrouillage est réalisée en deux pièces, le plan de joint se situe entre les deux parties des rampes de verrouillage. Les formes fonctionnelles de ces deux parties deviennent ainsi facilement réalisables quelque soit le mode de réalisation retenu, sans outil ou méthode complexe. L'assemblage est très simple et rapide, donc économique.The locking ring is made in two parts, the joint plane is between the two parts of the locking ramps. The functional forms of these two parts thus become easily achievable whatever the chosen embodiment, without tools or complex method. The assembly is very simple and fast, so economic.

Les deux pièces peuvent être moulées dans des outils très simples, puisqu'il n'y a aucune contre-dépouille sur les pièces.Both pieces can be molded in very simple tools, since there is no undercut on the pieces.

Grâce à ces dispositions, les moyens de réalisations employés sont bon marché.Thanks to these provisions, the means of realization employed are cheap.

Les Outillages de moulage sont plus simples, il est donc possible d'optimiser la conception des pièces (épaisseur constante, position des points d'injection, etc...).The molding tools are simpler, so it is possible to optimize the design of the parts (constant thickness, position of the injection points, etc ...).

Dans un mode de réalisation, la deuxième pièce s'emboite dans la première pièce par clipsage bloquant la translation de la première pièce par rapport à la deuxième pièce.In one embodiment, the second piece fits into the first piece by clipping blocking the translation of the first piece relative to the second piece.

Dans un mode de réalisation, la deuxième pièce s'emboite dans la première pièce jusqu'à une butée adaptée pour aligner l'extrémité de la première pièce à l'extrémité de la deuxième pièce.In one embodiment, the second piece fits into the first piece to a stop adapted to align the end of the first piece to the end of the second piece.

Dans un mode de réalisation, la deuxième pièce (24) a une densité supérieure à la première pièce.In one embodiment, the second piece (24) has a density greater than the first piece.

La matière de chaque pièce est choisie et adaptée au besoin, pour un coût réduit.The material of each piece is chosen and adapted as needed, for a reduced cost.

Dans un mode de réalisation, la deuxième pièce est en métal, de type Zamak moulé, ou en thermoplastique très haute performance.In one embodiment, the second piece is made of metal, molded Zamak type, or very high performance thermoplastic.

De manière très générale, on appelle ici matériau thermoplastique tout matériau comportant un certain pourcentage de matériau thermoplastique constituant une matrice, qu'il s'agisse d'un matériau constitué seulement de matériau thermoplastique ou encore par exemple d'un matériau composite à fibres continues et à matrice thermoplastique.Very generally, the term "thermoplastic material" refers to any material comprising a certain percentage of thermoplastic material constituting a matrix, whether it is a material consisting solely of thermoplastic material or, for example, of a continuous fiber composite material. and thermoplastic matrix.

On appelle ici matériau thermoplastique très haute performance tout matériau présentant une grande résistance, une bonne rigidité ainsi qu'une excellente résistance à l'hydrolyse, le tout sur une vaste plage de températures, les rendant aptes à des applications même sous des contraintes extrêmes. Le matériau thermoplastique très haute performance est notamment choisi parmi la famille des PAEK (pour polyaryléthercétones) : polyétheréthercétones (désigné par le sigle PEEK), polyéthercétonecétone (désigné par le sigle PEKK) ou un mélange des deux d'entre eux.Very high performance thermoplastic material is called any material having high strength, good rigidity and excellent resistance to hydrolysis, all over a wide range of temperatures, making them suitable for applications even under extreme constraints. The very high performance thermoplastic material is in particular chosen from the PAEK family (for polyaryletherketones): polyetheretherketones (designated by the acronym PEEK), polyetherketoneketone (designated by the acronym PEKK) or a mixture of the two of them.

Selon une autre variante, le matériau thermoplastique très haute performance est notamment choisi parmi poly(sulfure de phénylène) (désigné par le sigle PPS), polyamide-imide (désigné par le sigle PAI), polyéthersulfone (désigné par le sigle PES), polyétherimide (désigné par le sigle PEI), polymère à cristaux liquides (désigné par le sigle LCP), ou un mélange d'au moins deux d'entre eux.According to another variant, the very high performance thermoplastic material is in particular chosen from poly (phenylene sulphide) (designated by the acronym PPS), polyamide-imide (designated by the acronym PAI), polyethersulfone (designated by the acronym PES), polyetherimide (designated by the acronym PEI), a liquid crystal polymer (designated LCP), or a mixture of at least two of them.

Concernant la deuxième pièce, elle est réduite au strict minimum. Le choix du matériau est en rapport avec l'utilisation du connecteur. Ainsi pour améliorer la durée de vie du connecteur, la deuxième pièce est en métal ce qui améliore sa résistance au frottement. Pour réduire son poids, la deuxième pièce est en thermoplastique très haute performance. Ainsi, la surface est protégée et dans ce cas, la deuxième pièce évite les risques de corrosion.Regarding the second piece, it is reduced to the bare minimum. The choice of material is related to the use of the connector. Thus to improve the life of the connector, the second piece is metal which improves its resistance to friction. To reduce its weight, the second piece is very high performance thermoplastic. Thus, the surface is protected and in this case, the second part avoids the risk of corrosion.

Dans un mode de réalisation, la première pièce comporte sur sa surface cylindrique externe une partie de gorge en forme de U, V ou W adaptée pour la préhension de la première partie par une main. Ainsi, la bague de verrouillage permet une meilleure préhension d'une main pour le verrouillage manuel. Cette variante est plus ergonomique (forme mieux adaptée à la main).In one embodiment, the first part comprises on its outer cylindrical surface a U-shaped, V or W-shaped groove portion adapted for gripping the first part by a hand. Thus, the locking ring allows a better grip of a hand for manual locking. This variant is more ergonomic (shape better adapted to the hand).

DESCRIPTION D'EXEMPLES DE REALISATION DE L'INVENTIONDESCRIPTION OF EXAMPLES OF EMBODIMENT OF THE INVENTION

Les figures 1 à 3 ont été décrites précédemment.The Figures 1 to 3 have been described previously.

La figure 4 montre la première pièce 23 et la deuxième pièce 24 avant leur assemblage. La première pièce 23 comporte des encoches réparties sur toute la circonférence de la surface interne. La deuxième pièce 24 comporte des encoches réparties sur toute la circonférence de la surface externe. Les encoches de la première pièce 23 et les encoches de deuxième pièce 24 sont complémentaires.The figure 4 shows the first piece 23 and the second piece 24 before assembly. The first piece 23 has notches distributed over the entire circumference of the inner surface. The second piece 24 has notches distributed over the entire circumference of the outer surface. The notches of the first piece 23 and the notches of the second piece 24 are complementary.

La figure 5 montre l'assemblage de la première pièce 23 et la deuxième pièce 24. Lorsque ces deux pièces sont assemblées par translation dans le sens de l'axe longitudinal de la première pièce 23, la deuxième pièce 24 n'est plus mobile en rotation par rapport à la première pièce 23. Les encoches permettent de bloquer cette rotation.The figure 5 shows the assembly of the first part 23 and the second part 24. When these two parts are assembled by translation in the direction of the longitudinal axis of the first part 23, the second part 24 is no longer rotatable relative to to the first piece 23. The notches allow to block this rotation.

Les figures 6 et 7 montrent le positionnement d'un connecteur électrique 25 dans la bague de verrouillage. La première pièce 23 et la deuxième pièce 24 sont assemblées préalablement avant de positionner le connecteur électrique.The Figures 6 and 7 show the positioning of an electrical connector 25 in the locking ring. The first piece 23 and the second piece 24 are assembled beforehand prior to positioning the electrical connector.

La figure 8 représente une vue en coupe de la première pièce 23 et la deuxième pièce 24 avant leur assemblage. Sur cette figure, il est visible la première partie de rampe de la première pièce 23 et la deuxième partie de rampe de la deuxième pièce 24.The figure 8 represents a sectional view of the first part 23 and the second part 24 before assembly. In this figure, it is visible the first ramp portion of the first piece 23 and the second ramp portion of the second piece 24.

La figure 9 représente une vue en coupe de l'assemblage de la première pièce 23 et de la deuxième pièce 24. Il est montré une zone 26 qui permet d'observer la complémentarité de la deuxième partie de rampe avec la première partie de rampe. Sur cette figure il n'est visible qu'une première partie de rampe (vue en coupe), mais dans cette réalisation la première pièce 23 possède deux premières parties de rampe et la deuxième pièce possède deux deuxièmes parties de rampe.The figure 9 represents a sectional view of the assembly of the first part 23 and the second part 24. There is shown an area 26 which makes it possible to observe the complementarity of the second ramp portion with the first ramp portion. In this figure there is only visible a first ramp portion (sectional view), but in this embodiment the first part 23 has two first ramp parts and the second part has two second ramp parts.

Chaque partie de rampe est destinée à recevoir un ergot d'un connecteur électrique pour guider l'ergot vers la fin de la rampe qui verrouille le connecteur électrique circulaire. Il faut effectuer un mouvement poussé-tourné.Each ramp portion is adapted to receive a lug of an electrical connector for guiding the lug to the end of the ramp that locks the circular electrical connector. You have to make a push-and-turn motion.

La figure 10 représente en coupe de l'assemblage de la première pièce 23 et de la deuxième pièce 24, et permet de voir la variante avec clipage 27.The figure 10 represents in section of the assembly of the first part 23 and the second part 24, and allows to see the variant with clipping 27.

L'assemblage des deux pièces est réalisé par clipage dans l'axe principal de la pièce (axe de rotation), soit manuellement, soit automatiquement. On entend par clipage, le fait d'attacher à l'aide d'un clip.The assembly of the two parts is made by clipping in the main axis of the part (axis of rotation), either manually or automatically. Clipping is the act of attaching with a clip.

Dans ce cas, la face externe de la deuxième pièce 24 comporte un ergot (clip) qui bloque la deuxième pièce 24 par rapport à la première pièce 23. Comme la figure précédente, la deuxième partie de rampe complète la première partie de rampe.In this case, the outer face of the second part 24 comprises a lug (clip) which blocks the second part 24 relative to the first part 23. As in the previous figure, the second part of the ramp completes the first part of the ramp.

La partie de la rampe qui assure le verrouillage (deuxième pièce 24), se trouve être la plus sollicitée puisqu'elle encaisse les efforts de connexion des contacts, et de compression du joint d'accouplement. La deuxième pièce 24 est réalisée en métal (Zamak moulé), ou thermoplastique très haute performance.The part of the ramp which ensures the locking (second part 24), is the most requested since it cash the connection efforts of the contacts, and compression of the coupling joint. The second piece 24 is made of metal (molded Zamak), or very high performance thermoplastic.

La partie qui assure le déverrouillage (première pièce 23), et qui supporte donc moins d'efforts (frottement des contacts seulement) est réalisée en matière thermoplastique moulée plus ordinaire et très bon marché. Le matériau est donc choisi en fonction des sollicitations et des performances recherchées.The part which ensures the unlocking (first piece 23), and which therefore supports less effort (friction of the contacts only) is made of molded thermoplastic material more ordinary and very cheap. The material is chosen according to the demands and the desired performances.
