Description

L'invention vise des connecteurs électriques du type dit "hermaphrodite", c'est-à-dire constitué de deux éléments de boîtier identiques tournés tête bêche, sens dessus dessous et emboîtés l'un dans l'autre, chaque élé­ment de boîtier comportant une série de canaux destinés à recevoir chacun un organe de contacts électriques relié chacun à un conducteur, les organes de contacts électriques étant complémentaires afin que ceux de l'un des éléments de boîtier coïncident avec ceux de l'autre et vice versa.The invention relates to electrical connectors of the so-called "hermaphrodite" type, that is to say made up of two identical housing elements turned upside down, turned upside down and nested one inside the other, each housing element comprising a series of channels intended to each receive an electrical contact member each connected to a conductor, the electrical contact members being complementary so that those of one of the housing elements coincide with those of the other and vice versa.

On a constaté, quel que soit le soin apporté à la fabrication des boîtiers ou des organes de contacts électriques, que ces derniers pouvaient après montage dans leurs canaux respectifs ne pas se présenter tous de fa­çon identique de sorte, qu'au moment de l'assemblage des deux éléments de boîtier, ils pouvaient, au lieu de coïn­cider avec les organes complémentaires pour assurer la liai­son électrique buter contre ceux-ci et être forcés, ce qui risque d'entraîner un endommagement du boîtier ou des orga­nes eux-mêmes et en tous les cas une mauvaise liaison élec­trique. Un tel inconvénient est d'autant plus remarquable lorsque les connecteurs sont très petits et qu'ils comportent un grand nombre de voies.It has been found, however carefully taken in the manufacture of the housings or of the electrical contact members, that the latter could, after mounting in their respective channels, not all present themselves in an identical manner so that, at the time of the assembly of the two housing elements, they could, instead of coinciding with the complementary members to ensure the electrical connection abut against them and be forced, which may cause damage to the housing or the organs themselves and all cases a bad electrical connection. Such a drawback is all the more remarkable when the connectors are very small and when they have a large number of channels.

L'un des buts de la présente invention est de remédier à ces divers inconvénients.One of the aims of the present invention is to remedy these various drawbacks.

Le connecteur, selon l'invention, est du type dit "hermaphrodite" comprenant deux éléments de boîtier identiques dont l'un est tourné tête bêche sens dessus des­sous par rapport au premier, chaque élément comprenant une partie mâle destinée à s'insérer dans une partie femelle de l'autre élément et une partie femelle destinée à recevoir la partie mâle dudit autre élément, la partie mâle étant délimitée par deux parois latérales et deux autres parois, tandis que la partie femelle est délimitée par deux parois latérales et deux autres parois, chacune des parties mâles et femelles comportant une série de canaux destinés à rece­voir chacun un organe de contacts électriques relié à un conducteur électrique, lesdits organes de contacts électriques logés dans les canaux des parties mâles étant complémen­taires de ceux logés dans les canaux des parties femelles, et des moyens de verrouillage étant prévus pour maintenir assemblés lesdits éléments de boîtier, et les perfectionne­ments étant caractérisés en ce que la partie femelle de chaque élément de boîtier comporte sur des parois latérales des glissières tandis que la partie mâle de chaque élément de boîtier comporte sur ses parois latérales des barrettes en saillie destinées à coopérer avec les glissières chaque barrette étant pourvue, à son extrémité libre d'une rampe inclinée, la paroi de la partie mâle opposée à celle adja­cente à la partie femelle comportant une patte de verrouil­lage présentant une partie élastique raccordée à ladite paroi par une partie arrondie rigide, tandis que la face interne de la paroi correspondante de la partie femelle est pourvue d'un ergot destiné à coopérer, lors de l'assem­blage des deux éléments de boîtier avec la patte de verrouil­lage, la position de l'ergot, de la patte de verrouillage et des rampes inclinées étant telle, qu'au début de l'assem­blage des éléments de boîtier l'ergot doit gravir la par­tie arrondie et engendrer un déplacement, l'un par rapport à l'autre, desdits éléments dans des directions divergentes sensiblement perpendiculaires par rapport à l'axe d'engage­ment de l'un dans l'autre des éléments de boîtier, tandis qu'après que l'ergot ait gravi la partie arrondie les rampes en coopérant avec les glissières amènent les éléments dans la position normale d'assemblage.The connector according to the invention is of the so-called "hermaphrodite" type comprising two identical housing elements, one of which is turned upside down with respect to the first, each element comprising a male part intended to be inserted in a female part of the other element and a female part intended to receive the male part of said other element, the male part being delimited by two side walls and two other walls, while the female part is delimited by two side walls and two other walls , each of the male and female parts comprising a series of channels intended to each receive an electrical contact member connected to an electrical conductor, said electrical contact members housed in the channels of the male parts being complementary to those housed in the channels of the female parts, and locking means being provided to keep said housing elements assembled, and the improvements being characterized in that the female part of each housing element has on the side walls of the slides while the male part of each housing element has on its side walls of the projecting bars intended to cooperate with the slides each bar being provided, at its free end with an inclined ramp, the wall of the male part opposite to that adjacent to the female part comprising a locking tab having an elastic part connected to said wall by a rigid rounded part, while the internal face of the corresponding wall of the female part is provided with a lug intended to cooperate, during the assembly of the two housing elements with the locking tab, the position of the lug, of the locking tab and of the inclined ramps being such that, at the beginning of the assembly of the housing elements, the lug must climb the rounded part and cause a displacement, one relative to the other, of said elements in diverging directions substantially perpendicular to the axis of engagement of one in the other of the housing elements, while after the lug has climbed the rounded part of the ramps by cooperating with the slides bring the elements to the normal assembly position.

On conçoit, que, grâce à cette disposition on assurera une insertion rigoureuse des organes de contacts électriques.It is understood that, thanks to this arrangement, a rigorous insertion of the electrical contact members will be ensured.

Suivant une caractéristique de détail, la partie mâle comporte un logement dans lequel s'étend la patte élas­tique de verrouillage.According to a characteristic of detail, the male part comprises a housing in which the elastic locking tab extends.

Suivant un détail constructif, la patte élasti­que de verrouillage comporte une fente intermédiaire dans laquelle l'ergot s'insère en position verrouillée des deux éléments de boîtier, ledit ergot présentant à son extrémi­té tournée vers l'intérieur de l'élément, un abrupt et du côté opposé une partie arrondie, tandis que la patte élas­tique de verrouillage est terminée par un bossage. On réa­lise ainsi un verrouillage précis, efficace et simple des deux éléments de boîtier, le bossage permettant d'appuyer sur les pattes élastiques pour dégager l'ergot et permettre de désaccoupler les deux éléments.According to a constructive detail, the elastic locking tab has an intermediate slot in which the lug is inserted in the locked position of the two housing elements, said lug having at its end turned towards the inside of the element, a steep and on the opposite side a rounded part, while the elastic locking tab is ended with a boss. This produces a precise, efficient and simple locking of the two housing elements, the boss making it possible to press on the elastic tabs to release the lug and make it possible to uncouple the two elements.

Enfin, les organes de contacts électriques sont du type, connu en soi "hermaphrodite", et formés d'un corps pourvu à une extrémité de moyens pour sa fixation à un conduc­teur électrique, ledit corps affectant une section rectangu­laire avec une paroi de plancher pourvue d'un prolongement plié vers l'intérieur et terminé par une languette élasti­que tournée vers le prolongement.Finally, the electrical contact members are of the type, known per se "hermaphrodite", and formed of a body provided at one end with means for its attachment to an electrical conductor, said body affecting a rectangular section with a floor wall provided of an extension folded inwards and terminated by an elastic tongue facing the extension.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :

The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:
  • FIG. 1 is a schematic perspective view of a connection box according to the invention,
  • FIG. 2 is a perspective view showing an electrical contact member intended to equip the box of FIG. 1,

Aux différentes figures, on a représenté un mode de réalisation d'un boîtier et d'un organe de contact électrique hermaphrodite, c'est-à-dire que ces éléments sont destinés à coopérer avec des éléments identiques, mais l'invention, s'applique également à des organes de contacts électriques classiques mâles ou femelles ainsi qu'à des boîtiers comprenant une partie mâle et une partie femelle correspondante.In the various figures, an embodiment of a housing and a hermaphroditic electrical contact member is shown, that is to say that these elements are intended to cooperate with identical elements, but the invention, s 'also applies to conventional male or female electrical contact members as well as to housings comprising a male part and a corresponding female part.

Le boîtier représenté à la figure 1 est formé de deux éléments de boîtier 1 et 2 identiques qui sont assemblables l'un sur l'autre, après que l'un de ceux-ci ait été tourné tête bèche, sens dessus dessous.The housing shown in Figure 1 is formed of two identical housing elements 1 and 2 which can be assembled one on the other, after one of these has been turned upside down.

Chaque élément de boîtier 1 ou 2 comporte une partie 22 délimitée par des parois latérales 22a et des parois 22b et 22c et qui constitue la partie mâle, la par­tie femelle étant référencée en 23 et étant délimitée par des parois 23a, 23b et 23c.Each housing element 1 or 2 comprises a part 22 delimited by side walls 22a and walls 22b and 22c and which constitutes the male part, the female part being referenced at 23 and being delimited by walls 23a, 23b and 23c.

La partie mâle 22 comporte des canaux 3 destinés à recevoir chacun un organe de contact électrique 4, tandis que la partie 23 présente une série de canaux 3a destinés à recevoir chacun un organe de contact 4.The male part 22 has channels 3 intended to each receive an electrical contact member 4, while the part 23 has a series of channels 3a each intended to receive a contact member 4.

A la figure 2, on a représenté en perspective un organe 4, celui-ci étant réalisé en un métal bon conduc­teur de l'électricité présentant une certaine élasticité, ledit organe 4 présentant, à une extrémité, des pattes 5 destinées à enserrer une gaîne 6 d'un conducteur 8 et, des pattes 7 pour enserrer l'extrémité correspondante dénudée du conducteur.In Figure 2, there is shown in perspective a member 4, this being made of a metal good conductor of electricity having a certain elasticity, said member 4 having, at one end, tabs 5 intended to enclose a sheath 6 of a conductor 8 and, tabs 7 for enclosing the corresponding stripped end of the conductor.

L'organe 4 présente une paroi de plancher 9 pourvue d'un prolongement 10 plié pour former une languette élastique 11.The member 4 has a floor wall 9 provided with an extension 10 folded to form an elastic tongue 11.

L'organe 4 est conformé pour présenter deux parois latérales 13 et 14 qui sont terminées par des ra­bats 15 et 16 s'étendant sensiblement parallèlement au plan­cher 9 pour former une sorte de conduit à section rectangu­laire.The member 4 is shaped to have two side walls 13 and 14 which are terminated by flaps 15 and 16 extending substantially parallel to the floor 9 to form a sort of conduit with rectangular section.

Un tel organe 4 peut recevoir une simple bar­rette mâle inserée entre le prolongement 10 et la languette 11 ou être utilisé avec un organe identique, celui-ci étant alors tourné tête bèche sens dessus dessous et venant s'in­sérer, par son prolongement 10 contre le prolongement 10 de l'autre organe 4 et la languette plastique 11, le prolongement 10 dudit autre organe 4 s'insérant de la même façon entre le prolongement 10 et la languette 11 du premier organe 4.Such a member 4 can receive a simple male bar inserted between the extension 10 and the tongue 11 or be used with an identical member, the latter then being turned upside down and being inserted, by its extension 10 against the extension 10 of the other member 4 and the plastic tongue 11, the extension 10 of said other member 4 being inserted in the same way between the extension 10 and the tongue 11 of the first member 4.

La paroi de plancher 9 présente, au voisinage des pattes 7 un trou 18 qui est destiné à coopérer avec un ergot 19 porté par une patte élastique 20 prévue dans chaque canal 3.The floor wall 9 has, in the vicinity of the tabs 7, a hole 18 which is intended to cooperate with a lug 19 carried by an elastic tab 20 provided in each channel 3.

Chaque canal 3 présente également une butée 17 contre laquelle vient porter l'extrémité libre des rabats 15-16.Each channel 3 also has a stop 17 against which the free end of the flaps 15-16 comes to bear.

Ainsi, lorsqu'un organe de contact 4 est mis en place dans un canal 3, il est verrouillé.Thus, when a contact member 4 is placed in a channel 3, it is locked.

Chaque canal 3a de la partie 23 est sensiblement identique à un canal 3, mais est coformé pour permettre à la partie 22 de s'insérer dans ladite partie 23. Ainsi, la paroi 23b n'est pas au voisinage de son extrémités li­bre attenante aux parois latérales 23a afin de permettre aux parois 22a de s'engager dans la partie 23 et il est ménagé un espace libre 24 pour permettre à la paroi 22c de passer sous la paroi 23b.Each channel 3a of the part 23 is substantially identical to a channel 3, but is co-formed to allow the part 22 to fit into said part 23. Thus, the wall 23b is not in the vicinity of its free ends adjoining the side walls 23a in order to allow the walls 22a to engage in the part 23 and a free space 24 is provided to allow the wall 22c to pass under the wall 23b.

Chaque canal 3a comporte une butée 17a une patte élastique 20a avec un ergot 19a pour fixer et verrouiller un organe 4.Each channel 3a has a stop 17a an elastic tab 20a with a lug 19a for fixing and locking a member 4.

La partie 22 de chaque élément 1 ou 2 est pourvue d'une patte élastique de verrouillage 25 qui est solidaire par son extrémité 26 d'un renfort 30 de la paroi 22c, la­dite patte élastique de verrouillage 25 présentant une par­tie arquée rigide 27 prolongée par une partie élastique 31 percée d'une fente 28 et terminée par un bossage 29.The part 22 of each element 1 or 2 is provided with an elastic locking tab 25 which is integral by its end 26 with a reinforcement 30 of the wall 22c, said elastic locking tab 25 having a rigid arcuate part 27 extended by an elastic part 31 pierced with a slot 28 and terminated by a boss 29.

La patte élastique de verrouillage 25 est si­tuée dans un logement 33 ménagé dans une partie médiane de la paroi 22b de chaque élément.The elastic locking tab 25 is located in a housing 33 formed in a middle part of the wall 22b of each element.

La paroi 23c comporte un ergot 35 qui présente une partie arrondie 36 et un abrupt 37, cet ergot étant situé dans le plan de la patte élastique de verrouillage 25.The wall 23c comprises a lug 35 which has a rounded part 36 and a steep 37, this lug being located in the plane of the elastic locking tab 25.

Les parois latérales 22a de la partie 22 com­portent chacune au voisinage de la paroi 22b une barrette de guidage 38, celle-ci présentant une rampe inclinée 40.The side walls 22a of the part 22 each have, in the vicinity of the wall 22b, a guide bar 38, the latter having an inclined ramp 40.

La partie 23 est pourvue, dans ses parois la­térales 23a de glissières 39. Les glissières 39 de l'élément 1 étant destinées à recevoir les arêtes 38 de l'élément 2 et vice versa.The part 23 is provided, in its side walls 23a with slides 39. The slides 39 of the element 1 being intended to receive the edges 38 of the element 2 and vice versa.

On remarquera que l'ergot 35 est légèrement en retrait par rapport au bord de la paroi 23c.It will be noted that the lug 35 is slightly set back relative to the edge of the wall 23c.

Bien que les organes de contacts électriques soient fabriqués avec le maximum de soins et que les boîtiers soient également fabriqués avec une grande précision, sur­tout lorsque les éléments ont de très petites dimensions, il peut arriver que lorsqu'on emboîte l'élément 1 sur l'élé­ment 2 que les prolongements 10 de deux organes 4 dont est disposé dans un canal 3 d'un élément et l'autre dans le canal correspondant 3a de l'autre élément butent l'un contre l'autre. Dans ce cas soit, on ne peut assembler les éléments 1 et 2 du boîtier, soit, on force et l'un des organes est endommagé et la connexion électrique n'est pas parfaitement réalisée.Although the electrical contact members are manufactured with the utmost care and the housings are also manufactured with great precision, especially when the elements are very small, it can happen that when the element 1 is fitted on the element 2 that the extensions 10 of two members 4 which is disposed in a channel 3 of one element and the other in the corresponding channel 3a of the other element abut against one another. In this case either, one cannot assemble the elements 1 and 2 of the housing, or, one forces and one of the organs is damaged and the electrical connection is not perfectly carried out.

Les différentes phases d'insertion des éléments 1 et 2 permettent de comprendre l'invention qui remédie aux inconvénients ci-dessus exposés.The different phases of insertion of elements 1 and 2 make it possible to understand the invention which overcomes the drawbacks described above.

Lorsqu'on présente les deux éléments 1 et 2 pour les emboîter, la partie mâle 22 de l'un s'engage dans la partie femelle 23 de l'autre jusqu'à ce que les ergots 35 butent contre les parties arrondies 27 des pattes élas­tiques de verrouillage 25. Dans cette position les barrettes de guidage 38 sont, par leur extrémité pourvue de la rampe, juste légèrement engagées dans les glissières 39.When the two elements 1 and 2 are presented for fitting together, the male part 22 of one engages in the female part 23 of the other until the pins 35 abut against the rounded parts 27 of the legs locking elastic 25. In this position, the guide bars 38 are, by their end provided with the ramp, just slightly engaged in the slideways 39.

Si on continue l'insertion (voir figures 4, 5 et 6 "A") les ergots 35 sont obligés de gravir la partie arrondie 27 ce qui est possible puisque les extrémités des rampes 40 sont seulement engagées dans ces glissières 39 et qu'à ce niveau, il est formé entre ces deux derniers éléments un jeu important. Ainsi, il se forme un déplacement des deux éléments 1 et 2 dans deux directions opposées, perpendiculaire à l'axe d'insertion (voir flèche f). Ainsi, les prolongements 10 des organes 4 des canaux 3 se décalent en hauteur par rapport aux prolongements 10 des organes 4 des canaux 3a et vice versa.If the insertion is continued (see FIGS. 4, 5 and 6 "A") the pins 35 are forced to climb the rounded part 27 which is possible since the ends of the ramps 40 are only engaged in these slides 39 and that at this level, an important game is formed between these last two elements. Thus, a displacement of the two elements 1 and 2 is formed in two opposite directions, perpendicular to the insertion axis (see arrow f). Thus, the extensions 10 of the members 4 of the channels 3 shift in height relative to the extensions 10 of the members 4 of the channels 3a and vice versa.

En contituant l'insertion des éléments 1 et 2, ceux-ci restent au même niveau (voir figures 4, 5, 6 "B") jusqu'à ce que les ergots 35 dépassent les parties arrondies 27 des pattes de verrouillage 25 et que les rampes 40 s'engagent en totalité dans les glissières 39. La posi­tion B montre que les prolongements 10 ont été rapprochés pour s'engager l'un dans l'autre.Constituting the insertion of elements 1 and 2, these remain at the same level (see FIGS. 4, 5, 6 "B") until the pins 35 protrude beyond the parts rounded 27 of the locking tabs 25 and that the ramps 40 fully engage in the slides 39. Position B shows that the extensions 10 have been brought together to engage one in the other.

Simultanément (voir figures 4, 5, 6 "C") les ergots 35 dépassant les parties arrondies 27, les pattes élastiques de verrouillage 25 pouvant ployer, tandis que les barrettes de guidage 38 s'engagent dans les glissières 39 au niveau des extrémités des rampes 40. Ainsi, les élé­ments 1 et 2 sont déplacés dans le sens opposé (flèche g) au sens de déplacement initial du début de l'insertion pour être ramenés dans la position normale d'engagement. Les ergots 35 tombent ensuite dans les fentes 28 pour assurer le verrouillage des éléments 1 et 2 (voi figures 4,5,6 "D").Simultaneously (see FIGS. 4, 5, 6 "C") the pins 35 protruding from the rounded parts 27, the elastic locking tabs 25 can bend, while the guide bars 38 engage in the slides 39 at the ends of the ramps 40. Thus, the elements 1 and 2 are moved in the opposite direction (arrow g) to the initial direction of movement from the start of the insertion to be brought back to the normal position of engagement. The pins 35 then fall into the slots 28 to ensure the locking of the elements 1 and 2 (see Figures 4,5,6 "D").

Pour séparer les éléments 1 et 2, il suffit de presser les bossages 29 afin de dégager les ergots 35 des fentes 28 et de tirer sur lesdits éléments 1 et 2 dans des directions opposées.To separate the elements 1 and 2, it suffices to press the bosses 29 in order to release the lugs 35 from the slots 28 and to pull on said elements 1 and 2 in opposite directions.

On conçoit que l'invention évite un mauvais positionnement des organes de contacts électriques au dé­but du montage et supprime les risques d'une mauvaise con­nexion électrique entre les organes correspondants de deux éléments de boîtiers complémentaires.It is understood that the invention avoids improper positioning of the electrical contact members at the start of assembly and eliminates the risks of poor electrical connection between the corresponding members of two elements of complementary housings.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et repré­senté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
