Description

Domaine de l'inventionField of the invention

La présente invention se situe dans le domaine des fiches électriques coudées. Elle se rapporte plus particulièrement aux fiches coudées de dimensions réduites.The present invention is in the field of angled electrical plugs. It relates more particularly to bent plugs of reduced dimensions.

Etat de la techniqueState of the art

On connaît de nombreux types de fiches coudées.
A titre d'exemple, on peut citer celles qui sont décrites dans les documents brevets US 4,128,292 , WO 94/02976, US 4,480,887.
Un type de fiche coudée comprend un premier et d'un deuxième corps cylindriques creux fixés perpendiculairement l'un à l'autre, une extrémité du premier corps étant logée dans une extrémité du deuxième corps de manière à définir un passage continu entre les extrémités libres des deux corps.Many types of bent plugs are known.
By way of example, mention may be made of those described in US Pat. Nos. 4,128,292, WO 94/02976 and US 4,480,887.
One type of angled plug includes first and second hollow cylindrical bodies fixed perpendicularly to one another, one end of the first body being housed in one end of the second body so as to define a continuous passage between the free ends. of the two bodies.

Les fiches coudées sont en général utilisées lorsque l'encombrement ne permet pas d'utiliser une fiche rectiligne ou lorsque la destination du câble se situe dans une orientation trop en dehors de l'axe principal de la fiche. Accessoirement, la forme coudée permet de réduire les sollicitations exercées sur une fiche car le moment occasionné par une traction sur le câble est moindre.The angled plugs are generally used when the bulk does not allow to use a straight plug or when the destination of the cable is in an orientation too far from the main axis of the plug. Incidentally, the bent shape reduces the stress on a plug because the moment caused by pulling on the cable is less.

Les fiches coudées de l'état de la technique présentent cependant un certain nombre d'inconvénients :

  • Pièces complexes, d'où assemblage compliqué.
  • Pièces chères, principalement dû à leur complexité.
  • Etanchéité imparfaite.
  • Difficultés pour raccorder le câble.
However, the bent plugs of the state of the art have a number of disadvantages:
  • Complex parts, hence complicated assembly.
  • Expensive parts, mainly due to their complexity.
  • Imperfect sealing.
  • Difficulties to connect the cable.

Résumé de l'inventionSummary of the invention

La présente invention vise notamment à remédier aux problèmes précités.
Elle concerne une fiche électrique coudée telle que définie dans la revendication principale.The present invention aims in particular to remedy the aforementioned problems.
It relates to a bent electrical plug as defined in the main claim.

L'invention concerne également une cage cylindrique telle que définie dans la revendication 15.The invention also relates to a cylindrical cage as defined in claim 15.

L'invention sera mieux comprise à la lecture de la description détaillée qui va suivre et à l'examen des figures annexées qui représentent, à titre d'exemple non limitatif deux modes de réalisation de l'invention.The invention will be better understood on reading the detailed description which follows and on examining the appended figures which represent, by way of nonlimiting example, two embodiments of the invention.

  • La figure 9 montre une vue latérale de la cage cylindrique de la figure 5.Figure 9 shows a side view of the cylindrical cage of Figure 5.

La fiche coudée illustrée sur la figure 1 comprend un premier corps cylindrique creux 7 logé dans l'extrémité d'un deuxième corps cylindrique creux 6. Une extrémité du premier corps 7 est fermée par un bouchon 3. L'intérieur du premier corps 7 (voir les deux variantes illustrées sur les figures 2 et 6) comporte des contacts électriques 5 fixés dans un isolant 11. Un ensemble de fils conducteurs (non illustré pour des raisons de visibilité de l'invention) relié aux contacts électriques 5 est disposé à l'intérieur du deuxième corps 6. L'ensemble constitué par les deux extrémités liées des corps 6,7 est entouré d'une douille ressort 9 optionnelle, requise pour des connecteurs à verrouillage de type "push-pull".The bent plug illustrated in FIG. 1 comprises a first hollow cylindrical body 7 housed in the end of a second hollow cylindrical body 6. An end of the first body 7 is closed by a plug 3. The interior of the first body 7 ( see the two variants illustrated in Figures 2 and 6) comprises electrical contacts 5 fixed in an insulator 11. A set of conductive son (not shown for reasons of visibility of the invention) connected to the electrical contacts 5 is arranged to The inside of the second body 6. The assembly constituted by the two connected ends of the bodies 6, 7 is surrounded by an optional spring bushing 9 , required for push-pull locking connectors.

L'extrémité du premier corps 7 logée dans le deuxième corps 6 est entourée d'un joint d'étanchéité de type O-ring 16. The end of the first body 7 housed in the second body 6 is surrounded by an O-ring type seal 16.

Un deuxième joint d'étanchéité du type O-ring 17 est situé entre le premier corps 7 et le deuxième corps 6, à l'intérieur du deuxième corps 6 de manière à assurer également un contact électrique optimal entre les corps 6,7. A second seal O-ring type 17 is located between the first body 7 and the second body 6, inside the second body 6 so as to also ensure optimum electrical contact between the body 6,7.

Une problématique classique des connecteurs coudés provient du fait que le bloc de contact, constitué essentiellement par les contacts électriques 5 et l'isolant 11, doit être amovible afin de permettre la fixation du câble aux contacts, préalablement à l'insertion de ce bloc dans le boîtier.
Il est nécessaire ensuite de maintenir ce bloc en place à l'aide d'une pièce rigide appuyant à l'avant sur le bloc et butant sur le bouchon de fermeture 3. Sans un maintien ferme, le bloc pourrait se déplacer lors de la manipulation et le contact électrique serait mal assuré.A classic problem of angled connectors comes from the fact that the contact block, consisting essentially of the electrical contacts 5 and the insulator 11, must be removable in order to allow the attachment of the cable contacts, prior to the insertion of this block in The box.
It is then necessary to maintain this block in place using a rigid piece pressing forward on the block and abutting on the closure cap 3. Without a firm hold, the block could move during handling and the electrical contact would be insecure.

L'assemblage d'un tel connecteur faisant intervenir de nombreuses pièces complexes, il en résulte que l'espace longitudinal disponible pour la cage au sein du corps est sujet à un plage de tolérance importante. Dans les conceptions classiques cela amène un problème fonctionnel, car la pièce rigide est sous-dimensionnée en longueur pour compenser ces tolérances, mais alors le bloc n'est pas bien maintenu, soit la pièce rigide est sur-dimensionnée pour offrir une bonne tenue du bloc mais alors la fermeture du bouchon au niveau du joint est insuffisante.The assembly of such a connector involving many complex parts, it follows that the longitudinal space available for the cage within the body is subject to a large tolerance range. In conventional designs this brings a functional problem, because the rigid part is undersized in length to compensate for these tolerances, but then the block is not well maintained, the rigid part is over-sized to provide good performance of the block but then closing the cap at the joint is insufficient.

La variante illustrée sur les figures 2 à 5 utilise une cage 4 présentant une partie élastique à l'arrière sous forme d'un cône fendu 18, 19. La cage 4 comporte en outre un évidement 23 formé sur sa paroi longitudinale et disposé du côté de l'extrémité libre du deuxième corps cylindrique. La largeur de l'évidement 23 s'étend de préférence sur environ 180° autour de l'axe principal de la cage.The variant illustrated in Figures 2 to 5 uses a cage 4 having an elastic portion at the rear in the form of a split cone 18, 19. The cage 4 further comprises a recess 23 formed on its longitudinal wall and disposed on the side of the free end of the second cylindrical body. The width of the recess 23 preferably extends about 180 ° around the main axis of the cage.

Les dimensions, positions, formes ainsi que le nombres des fentes 19 peuvent être adaptée aux dimensions et formes du connecteur pour assurer la fonction de manière optimale.The dimensions, positions, shapes as well as the number of slots 19 can be adapted to the dimensions and shapes of the connector to perform the function optimally.

Avantageusement, la cage 4 peut être sur-dimensionnée pour assurer la tenue du bloc de contact, tout en permettant, par la flexion des parties formant le cône 18, une fermeture totale du bouchon 3 et un serrage du joint 13 qui se situe entre les deux éléments de corps 6,7. Advantageously, the cage 4 can be oversized to ensure the holding of the contact block, while allowing, by bending the parts forming the cone 18, a total closure of the plug 3 and a tightening of the seal 13 which is between the two body elements 6,7.

La variante illustrée sur les figures 6 à 9 a exactement la même fonction que la variante précitée. Elle diffère de celle-ci en ce que la partie élastique de la cage 4 est réalisée par une fente 20 perpendiculaire à son axe, cette fente 20 est située proche de l'extrémité de la cage 4 en contact avec le bouchon 3. L'extrémité de la cage 4 étant fermée et formant un disque 21. L'élasticité peut être choisie en fonction de l'épaisseur du disque 21 et des dimensions de la fente 20. Le disque 21 comporte une protubérance 22 pour assurer un contact mécanique élastique et une force de rappel bien contrôlée, quelque soit les tolérances des pièces du boîtier. La hauteur de la protubérance 22 et la largeur de la fente 20 sont déterminées en fonction du jeu que l'on souhaite compenser.
Cette variante offre l'avantage d'obtenir une élasticité qui se contrôle par la dimension et la position de la fente, le résultat est bien maîtrisable.The variant illustrated in Figures 6 to 9 has exactly the same function as the aforementioned variant. It differs from this in that the elastic portion of the cage 4 is formed by a slot 20 perpendicular to its axis, this slot 20 is located near the end of the cage 4 in contact with the plug 3. The end of the cage 4 being closed and forming a disc 21. The elasticity can be chosen as a function of the thickness of the disc 21 and the dimensions of the slot 20. The disc 21 has a protrusion 22 to ensure elastic mechanical contact and a well-controlled restoring force, whatever the tolerances of the housing parts. The height of the protrusion 22 and the width of the slot 20 are determined according to the game that is to be compensated.
This variant offers the advantage of obtaining an elasticity that is controlled by the size and position of the slot, the result is well controllable.

Selon un mode de réalisation des deux variantes précédentes (voir figures 3 et 5), la cage comporte plusieurs fentes 15, par exemple quatre fentes distantes de 90°, qui sont disposées sur sa longueur. Ces fentes 15 sont destinées à recevoir des protubérances qui font partie de l'isolant 11, ce qui assure une bonne orientation de la cage 4, garantissant ainsi le maintien de l'évidement 23 en position adéquate pour le passage des câbles.According to one embodiment of the two previous variants (see Figures 3 and 5), the cage has a plurality of slots 15, for example four slots 90 ° apart, which are arranged along its length. These slots 15 are intended to receive protrusions which are part of the insulator 11, which ensures a good orientation of the cage 4, thereby ensuring the retention of the recess 23 in a position suitable for the passage of cables.

Une autre forme de réalisation de l'invention, non-illustrée, consiste en une cage, par exemple avec une partie conique sans fentes. De préférence, la cage est sensiblement sous-dimensionnée par rapport au logement dans le premier corps cylindrique 7. L'espace entre la cage 4 et le bouchon 3 est compensé par une pièce élastique, par exemple en élastomère ou constituée d'un ressort métallique. La fonction ainsi réalisée est la même que celle obtenue avec la cage représentée aux figures 2 et 6.Another embodiment of the invention, not illustrated, consists of a cage, for example with a conical portion without slots. Preferably, the cage is substantially undersized with respect to the housing in the first cylindrical body 7. The space between the cage 4 and the plug 3 is compensated by a elastic piece, for example of elastomer or constituted by a metal spring. The function thus produced is the same as that obtained with the cage represented in FIGS. 2 and 6.

La cage selon l'invention peut être réalisée de diverses manières, par exemple en métal usinée ou emboutie ou bien moulée en métal ou en matière plastique. La forme finale de la cage peut présenter des aspect très divers, notamment en fonction du matériau choisi pour la réaliser.The cage according to the invention can be made in various ways, for example machined metal or stamped or molded metal or plastic. The final shape of the cage may have a very diverse appearance, in particular depending on the material chosen to make it.
