Description

La présente invention concerne un dispositif de connexion de fils conducteurs gainés, notamment un dispositif dans lequel les fils sont simultanément dénudés et bloqués.The present invention relates to a device for connecting sheathed conductive wires, in particular a device in which the wires are simultaneously stripped and blocked.

On connait déjà un dispositif de connexion d'au moins deux fils conducteurs entourés chacun d'une gaine isolante, comprenant un bottier, dans lequel est ménagé un passage d'introduction d'une portion d'extrémité des fils gainés, des moyens de réception des dites portions d'extrémité dans le boîtier, et des moyens au moins partiellement conducteurs,agencés pour être introduits dans le boîtier transversalement aux gaines et coopérer avec les moyens de réception des gaines afin de dénuder et bloquer les fils.There is already known a device for connecting at least two conductive wires each surrounded by an insulating sheath, comprising a shoemaker, in which is provided a passage for introducing an end portion of the sheathed wires, receiving means said end portions in the housing, and at least partially conductive means, arranged to be introduced into the housing transversely to the sheaths and cooperate with the sheath receiving means in order to strip and block the wires.

En particulier, on connait un dispositif du type décrit ci-dessus, dans lequel les moyens pour dénuder les fils consistent en un linguet métallique comprenant deux fentes verticales dont la largeur est égale ou légèrement inférieure au diamètre de l'âme des fils.In particular, a device of the type described above is known, in which the means for stripping the wires consist of a metal latch comprising two vertical slots whose width is equal to or slightly less than the diameter of the core of the wires.

Lorsque le linguet est amené transversalement aux fils, la gaine est chassée pour laisser apparaître l'âme du fil, et l'âme du fil est enfoncée par forçage dans les fentes, pour rester en contact avec le linguet. Ainsi, chacun des conducteurs étant en contact avec le linguet, ils sont par conséquent électriquement connectés.When the latch is brought transversely to the wires, the sheath is driven out to reveal the core of the wire, and the core of the wire is forced into the slots, to remain in contact with the latch. Thus, each of the conductors being in contact with the latch, they are therefore electrically connected.

Cependant le dispositif ci-dessus présente des inconvénients.However, the above device has drawbacks.

Tout d'abord, la solidité de l'ensemble n'est pas excellente du fait que le fil n'est maintenu en place que par cette fente, de largeur faible, et que ce n'est pratiquement que sur le conducteur que le blocage s'effectue.First of all, the solidity of the assembly is not excellent because the wire is only held in place by this slit, of small width, and that it is practically only on the conductor that the blocking takes place.

De plus, ce dispositif peut endommager le fil lors de la mise en contact.In addition, this device can damage the wire when brought into contact.

En outre, la surface de contact entre chacun des conducteurs et le linguet est petite, au détriment de la qualité de la conduction.In addition, the contact surface between each of the conductors and the pawl is small, to the detriment of the quality of the conduction.

La présente invention vise à pallier ces inconvénients et à proposer un dispositif de connexion qui permette d'assurer par des opérations simples, une bonne conduction électrique, et une liaison mécanique robuste.The present invention aims to overcome these drawbacks and to propose a connection device which makes it possible to ensure, by simple operations, good electrical conduction, and a robust mechanical connection.

A cet effet, la présente invention concerne un dispositif de connexion d'au moins deux fils conducteurs entourés chacun d'une gaine isolante, comprenant un bottier dans lequel est ménagé un passage d'introduction d'une portion d'extrémité des fils gainés, des moyens de réception des dites portions d'extrémité dans le boîtier, et des moyens au moins partiellement conducteurs, agencés pour être introduits dans le boîtier transversalement aux gaines et coopérer avec les moyens de réception des gaines afin de dénuder et bloquer les fils, dispositif caractérisé par le fait que les moyens pour dénuder les fils sont agencés pour couder la portion d'extrémité des fils gainés et dénuder les fils longitudinalement.To this end, the present invention relates to a device for connecting at least two conductive wires each surrounded by an insulating sheath, comprising a housing in which is provided a passage for introducing an end portion of the sheathed wires, means for receiving said end portions in the housing, and means at least partially conductive, arranged to be introduced into the housing transversely to the sheaths and cooperate with the means for receiving the sheaths in order to strip and block the wires, device characterized by the fact that the means for stripping the wires are arranged to bend the end portion of the sheathed wires and strip the wires longitudinally.

Ainsi, le dispositif selon l'invention, avec lequel les fils sont coudés avant qu'ils ne soient dénudés, permet d'obtenir un contact électrique et un blocage sûrs, du fait que l'âme conductrice ne risque pas d'être endommagée.Thus, the device according to the invention, with which the wires are bent before they are stripped, makes it possible to obtain secure electrical contact and blocking, since the conductive core is not likely to be damaged.

De plus, la surface de contact électrique et de blocage mécanique est grande, ce qui est avantageux, et propre.In addition, the electrical contact and mechanical blocking surface is large, which is advantageous, and clean.

Dans une forme de réalisation préférée de l'invention, les moyens pour dénuder les fils présentent une certaine élasticité, ce qui permet la connexion efficace de conducteurs de différents diamètres.In a preferred embodiment of the invention, the means for stripping the wires have a certain elasticity, which allows the efficient connection of conductors of different diameters.

En outre, et de façon avantageuse, un même dispositif peut connecter trois fils,voire plus, et ce, de façon tout aussi efficace.In addition, and advantageously, the same device can connect three or more wires, and this, just as effectively.

Enfin, le dispositif selon l'invention, outre les avantages ci-dessus, conserve les avantages des dispositifs précédents, à savoir une introduction des fils simple et rectiligne, puis une poussée des dits moyens pour dénuder les fils dans le bottier, par exemple à l'aide d'une pince universelle.Finally, the device according to the invention, in addition to the above advantages, retains the advantages of the preceding devices, namely an introduction of the simple and straight wires, then a push of the said means for stripping the wires in the case, for example at using universal pliers.

Les moyens de réception peuvent comprendre un linguet de réception fixé rigidement au boîtier, ce linguet comportant une ouverture destinée à être traversée par les fils.The receiving means may comprise a receiving latch rigidly fixed to the housing, this latch comprising an opening intended to be crossed by the wires.

Les moyens pour dénuder les fils comprennent alors un clip métallique recourbé sur plus de 90° sur chacun de ses bords, et agencé pour s'emboîter sur le linguet. Le clip comporte une arête de coupe qui, en longeant le linguet, vient attaquer les portions d'extrémité des fils gainés s'étendant au-delà de l'ouverture du linguet pour les couder en les repliant le long du linguet, et pour les dénuder longitudinalement, dégageant ainsi l'âme de chacun des fils, pour les mettre en contact par son intermédiaire.The means for stripping the wires then comprise a metal clip curved over more than 90 ° on each of its edges, and arranged to fit onto the latch. The clip has a cutting edge which, along the latch, attacks the end portions of the sheathed wires extending beyond the opening of the latch to bend them by folding them along the latch, and for the strip longitudinally, thus freeing the core of each of the wires, to put them in contact through it.

L'invention sera bien comprise à la lecture de la description d'une forme de réalisation préférée du dispositif de l'invention, faite en référence aux dessins annexés sur lesquels :

Le dispositif représenté (fig. 2) comporte un bottier 1 sensiblement parallélépipédique et comportant sur une de ses faces frontales une cheminée 2 d'amenée des fils, de section sensiblement rectangulaire.The device shown (Fig. 2) comprises a casing 1 substantially parallelepiped and comprising on one of its front faces a chimney 2 for supplying the wires, of substantially rectangular section.

Le bottier est ouvert sur sa face supérieure. Le bottier peut être par exemple en matière plastique moulée.The case is open on its upper side. The case may for example be made of molded plastic.

A l'intérieur du boîtier, perpendiculaire à sa face ouverte et faisant face à l'ouverture de la cheminée 2, se trouve un linguet de réception 3, rigide, de forme sensiblement rectangulaire, et comportant dans le prolongement de la cheminée 2, une ouverture 4 destinée à être traversée par les fils, et dont la section est sensiblement égale à celle de la cheminée 2 (fig. 4), ou de préférence légèrement supérieure. Le linguet 3 comporte à sa base (fig.3), deux ergots de centrage 5, 6, destinés, lorsque celui-ci est placé dans le boîtier, à lui donner une position correcte. La partie supérieure du linguet 3 est sensiblement moins large que la longueur intérieure du boîtier 1, pour des motifs expliqués ultérieurement.Inside the housing, perpendicular to its open face and facing the opening of the chimney 2, there is a receiving latch 3, rigid, of substantially rectangular shape, and comprising in the extension of the chimney 2, a opening 4 intended to be crossed by the wires, and whose section is substantially equal to that of the chimney 2 (fig. 4), or preferably slightly greater. The latch 3 has at its base (fig. 3), two centering lugs 5, 6, intended, when the latter is placed in the housing, to give it a position correct. The upper part of the latch 3 is substantially less wide than the interior length of the housing 1, for reasons explained later.

Le dispositif comporte en outre un tiroir creux 9 (fig. l) également de forme générale parallélépipédique, et dont les dimensions extérieures sont sensiblement égales aux dimensions intérieures du boîtier 1. Il peut être également en matière plastique moulée. Le tiroir 9 comporte une face ouverte et, sur une de ses faces frontales 10, un évidement 11. On verra plus loin l'intérêt d'une telle conformation du tiroir.The device further comprises a hollow drawer 9 (FIG. 1) also of generally parallelepipedal shape, and the external dimensions of which are substantially equal to the internal dimensions of the housing 1. It can also be made of molded plastic. The drawer 9 has an open face and, on one of its front faces 10, a recess 11. We will see below the advantage of such a configuration of the drawer.

L'intérieur du tiroir 9 est conformé de manière à recevoir et à maintenir en place un clip métallique 12, par exemple en bronze phosphoreux, résistant et bon conducteur de l'électricité. Le clip 12 consiste en une plaquette sensiblement rectangulaire, dont les bords les plus étroits ont été préalablement recourbés d'un angle d'environ 270°, chacun du même c8té. Il faut noter qu'en toute rigueur un angle supérieur à 90° assurerait la fonction. Le diamètre des recourbements et l'épaisseur de la plaquette formant le clip 12 sont tels que celui-ci peut, comme on le verra plus loin, venir coopérer étroitement, par emboîtage, avec le linguet 3. De la même manière, le linguet 3 peut avoir ses bords recourbés, à la place de ceux du clip 12, qui alors serait plan, mais c'est une solution moins satisfaisante.The interior of the drawer 9 is shaped so as to receive and hold in place a metal clip 12, for example made of phosphorous bronze, resistant and good conductor of electricity. The clip 12 consists of a substantially rectangular plate, the narrowest edges of which have been previously curved at an angle of approximately 270 °, each of the same side. It should be noted that in all rigor an angle greater than 90 ° would ensure the function. The diameter of the bends and the thickness of the plate forming the clip 12 are such that the latter can, as will be seen below, come to cooperate closely, by fitting, with the latch 3. In the same way, the latch 3 may have its curved edges, in place of those of the clip 12, which would then be flat, but this is a less satisfactory solution.

Pour l'assemblage préalable du tiroir 9 et de son clip 12, on dispose le clip 12 dans le tiroir 9, de sorte que les deux recourbements viennent en regard de la face 10 comportant l'évidement 11. Dans le présent exemple, le clip 12 est maintenu en place dans le tiroir 9 par forçage, et son positionnement est assuré par des rainures 14, 15 situées sur les faces latérales du tiroir (fig. 7). Le fonctionnement du dispositif est le suivant.For the prior assembly of the drawer 9 and its clip 12, the clip 12 is placed in the drawer 9, so that the two bends come opposite the face 10 comprising the recess 11. In the present example, the clip 12 is held in place in the drawer 9 by forcing, and its positioning is ensured by grooves 14, 15 located on the lateral faces of the drawer (fig. 7). The operation of the device is as follows.

On introduit par le passage d'introduction, ou cheminée, 2, les extrémités, non dénudées, des fils conducteurs gainés 16, 17 à raccorder électriquement et mécaniquement.Is introduced through the introduction passage, or chimney, 2, the ends, not stripped, sheathed conductive son 16, 17 to be connected electrically and mechanically.

Les fils sont introduits de sorte que leur portion d'extrémité traverse l'ouverture 4 du linguet de réception 3 et vienne en butée contre la face la du boîtier, face opposée à la face portant la cheminée 2. C'est cette étape qui est illustrée sur la fig. 5 des dessins.The wires are introduced so that their end portion passes through the opening 4 of the receiving latch 3 and comes into abutment against the face 1a of the housing, face opposite to the face carrying the chimney 2. It is this step which is illustrated in fig. 5 of the drawings.

Puis le tiroir 9 est amené contre le bottier 1 de sorte que leurs faces ouvertes coïncident et soient parallèles.Then the drawer 9 is brought against the case 1 so that their open faces coincide and are parallel.

Il faut noter que le linguet 3 et le clip 12 sont respectivement placés dans le bottier 1 et le tiroir 9 de sorte que, lorsque le tiroir pénètre dans le bottier, le clip 12 vient s'emboîter sur le linguet 3, ses deux recourbements entourant les bords du linguet.It should be noted that the latch 3 and the clip 12 are respectively placed in the case 1 and the drawer 9 so that, when the drawer enters the case, the clip 12 comes to fit on the latch 3, its two bends surrounding the edges of the latch.

L'étape suivante du fonctionnement, ou du montage, est illustrée à la fig. 6. Le tiroir 9 muni du clip 12 a été poussé dans le sens de la flèche 18, vers l'intérieur du boîtier 1, par exemple à l'aide d'une pince universelle, jusqu'à ce que l'arête de coupe, c'est-à-dire l'arête inférieure 13 du clip 12 atteigne, puis dépasse l'ouverture 4 du linguet 3. On comprend alors bien l'utilité de l'évidement 11, qui permet l'enfoncement du tiroir 9 dans le bottier 1 sans que la position des fils entre la cheminée et le linguet soit altérée. On comprend aussi, comme il est écrit plus haut, la nécessité d'un centrage relativement précis du linguet, ainsi que des espaces latéraux entre le boîtier et le linguet.The next stage of operation, or assembly, is illustrated in fig. 6. The drawer 9 provided with the clip 12 has been pushed in the direction of the arrow 18, towards the inside of the housing 1, for example using a universal pliers, until the cutting edge , that is to say the lower edge 13 of the clip 12 reaches, then exceeds the opening 4 of the latch 3. We then understand the utility of the recess 11, which allows the drawer 9 to be pushed into the shoemaker 1 without the position of the wires between the chimney and the latch being altered. We also understand, as it is written above, the need for relatively precise centering of the pawl, as well as lateral spaces between the housing and the pawl.

On comprend bien que l'arête de coupe en descendant, pousse tout d'abord les fils gainés, si nécessaire, contre le bord inférieur 4a de l'ouverture 4; alors, le déplacement relatif de l'arête de coupe 13 et du bord 4a se poursuivant, celui-ci provoque le pinçage puis le coudage des fils gainés, du côté de leur portion d'extrémité, c'est-à-dire du côté du linguet où l'arête de coupe 13 agit.We understand that the cutting edge down, first pushes the sheathed wires, if necessary, against the lower edge 4a of the opening 4; then, the relative displacement of the cutting edge 13 and of the edge 4a continuing, this causes the pinching then the bending of the sheathed wires, on the side of their end portion, that is to say on the side of the latch where the cutting edge 13 acts.

Ce déplacement relatif s'effectuant perpendiculairement à la direction des fils gainés, l'angle de coudage vaut alors sensiblement 90°.This relative movement taking place perpendicular to the direction of the sheathed wires, the bending angle is then substantially 90 °.

On peut cependant, sans sortir du cadre de l'invention, effectuer ce mouvement relatif du linguet et du clip dans un plan éventuellement non perpendiculaire à la direction des fils, mais avec un angle assez important, afin qu'un coudage réel existe.It is however possible, without departing from the scope of the invention, to effect this relative movement of the latch and of the clip in a plane possibly not perpendicular to the direction of the wires, but with a fairly large angle, so that real bending exists.

Dans son mouvement, le clip coopérant avec le linguet pour effectuer le coudage des gaines, attaque celles-ci par son arête de coupe dans leur sens longitudinal, pour en découper une partie, qui est chassée vers le bas et simultanément nettoyer les surfaces de contact conductrices. Chaque fil conducteur est alors)par sa portion d'extrémité.plongitudinalement dénudé du côté du clip et en contact électrique avec le clip. Par conséquent, les âmes des fils sont en contact électrique entre elles. On notera que si l'écartement du linguet et du clip est inférieur au diamètre des fils, on chassera une deuxième partie des gaines diamétralement opposées à la précédente, ce qui augmentera la surface de contact par le linguet, si celui-ci est conducteur.In its movement, the clip cooperating with the latch to effect the bending of the sheaths, attacks these by its cutting edge in their longitudinal direction, to cut a part, which is driven downwards and simultaneously clean the contact surfaces conductive. Each conductive wire is then ) by its end portion. Longitudinally stripped from the side of the clip and in electrical contact with the clip. Consequently, the cores of the wires are in electrical contact with one another. It will be noted that if the spacing of the latch and of the clip is less than the diameter of the wires, a second part of the sheaths diametrically opposite to the previous one will be driven out, which will increase the contact surface by the latch, if the latter is conductive.

Lorsque le tiroir 9, muni du clip 12, a été totalement enfoncé dans le boîtier, c'est-à-dire lorsqu'il vient, par les arêtes délimitant sa face ouverte, en butée contre le fond du boîtier 1 et que le plan du fond du tiroir et les arêtes délimitant la face ouverte du boîtier sont alignés, les fils partiellement dénudés sont très solidement maintenus en place entre les faces adjacentes du linguet de réception 3 et du clip de dénudage 12.When the drawer 9, fitted with the clip 12, has been fully inserted into the housing, that is to say when it comes, by the edges delimiting its open face, in abutment against the bottom of the housing 1 and that the plane from the bottom of the drawer and the edges delimiting the open face of the housing are aligned, the partially stripped wires are very securely held in place between the adjacent faces of the receiving latch 3 and the stripping clip 12.

On remarque, sur la fig. 1, que le tiroir 9 comporte deux ergots latéraux 9a, 9b, destinés, lorsque le tiroir est complètement enfoncé, à venir coopérer avec des évidements 7, 8 prévus dans le boîtier, afin de maintenir l'ensemble solidement fermé. On constate que les ergots de centrage 5, 6 du linguet 3 pourraient empêcher le tiroir d'attein- dre le fond du bottier. Pour éviter ceci, sont prévus, sur les parois latérales du tiroir, deux évidements 9c, 9d, sensiblement adjacents aux ergots 9a, 9b.We notice, in fig. 1, that the drawer 9 has two lateral pins 9a, 9b, intended, when the drawer is fully inserted, to cooperate with recesses 7, 8 provided in the housing, in order to keep the assembly securely closed. It can be seen that the centering lugs 5, 6 of the latch 3 could prevent the drawer from reaching the bottom of the case. To avoid this, two recesses 9c, 9d are provided on the side walls of the drawer, substantially adjacent to the lugs 9a, 9b.

Il est intéressant de constater que les fils sont maintenus à la fois par leur âme conductrice et par leur gaine, au profit de la résistance de l'ensemble, notamment, à une traction accidentelle des fils.It is interesting to note that the wires are held both by their conductive core and by their sheath, to the benefit of the resistance of the assembly, in particular, to accidental traction of the wires.

De plus, c'est sur toute la portion d'extrémité des fils que le contact est assuré avec le clip.In addition, it is over the entire end portion of the wires that contact is ensured with the clip.

En outre, on peut, avec le dispositif décrit ci-dessus, réaliser la connexion simultanée de plusieurs fils, dans la mesure où il est possible de tous les loger dans le boîtier et de les passer à travers le passage 4 du linguet 3.In addition, it is possible, with the device described above, to make the simultaneous connection of several wires, insofar as it is possible to house them all in the housing and to pass them through the passage 4 of the latch 3.

Enfin, on peut connecter ensemble des fils de différents diamètres, grâce à la relative élasticité de la plaquette formant le clip. En effet, cette élasticité permet d'obtenir, localement, une distance optimale entre le clip et le linguet, en fonction des dimensions des fils dont la connexion est à établir.Finally, we can connect together wires of different diameters, thanks to the relative elasticity of the plate forming the clip. Indeed, this elasticity makes it possible to obtain, locally, an optimal distance between the clip and the latch, according to the dimensions of the wires whose connection is to be established.

D'autre part, pour des raisons de commodité, on peut prévoir à l'intérieur du bottier, verticalement alignés avec les évidements 7, 8, deux évidements supplémentaires 7', 8' destinés à pré-introduire dans le boîtier 1 le tiroir 9, de façon rigide, grâce aux dits ergots 9a, 9b du tiroir, la position du tiroir 9 étant alors telle que l'ouverture 4 du linguet 3 n'est pas obturée par le clip 12. Les fils gainés peuvent alors être introduits sans encombre, comme décrit plus haut.On the other hand, for reasons of convenience, one can provide inside the case, vertically aligned with the recesses 7, 8, two additional recesses 7 ', 8' intended to pre-introduce the drawer 9 into the housing 1, rigidly, thanks to the said lugs 9a, 9b of the drawer, the position of the drawer 9 then being such that the opening 4 of the latch 3 is not closed by the clip 12. The sheathed wires can then be introduced without hindrance, as described above.

Enfin, pour maintenir le linguet fermement en place dans le boîtier, on peut prévoir de lui donner un empattement, c'est-à-dire sa largeur au niveau des ergots 5, 6, légèrement plus grand que la largeur du bottier dans la région correspondante, de sorte que les ergots viennent s'ancrer dans les parois du boîtier, en un matériau approprié à cet effet, en les déformant.Finally, to keep the latch firmly in place in the case, provision can be made to give it a wheelbase, that is to say its width at the level of the pins 5, 6, slightly larger than the width of the case in the region. corresponding, so that the pins are anchored in the walls of the housing, in a material suitable for this purpose, by deforming them.

Bien entendu, toutes les modifications de forme du dispositif, n'affectant pas ses fonctions essentielles, pourront être réalisées sans sortir du cadre de l'invention. Notamment le linguet peut ou non être métallique dans la mesure où il ne joue pas un rôle de conducteur. Il peut par exemple être monobloc avec le boîtier. De même, le clip peut éventuellement être partiellement non conducteur. Seule sa face en contact avec les âmes des fils, après montage, doit assurer une bonne conduction électrique.Of course, all the modifications of the form of the device, not affecting its essential functions, can be carried out without departing from the scope of the invention. In particular, the latch may or may not be metallic insofar as it does not play a conducting role. It can for example be monobloc with the housing. Likewise, the clip may possibly be partially non-conductive. Only its face in contact with the cores of the wires, after assembly, must ensure good electrical conduction.

Enfin, le clip et le linguet pourront respectivement être positionnés et maintenus fermement dans le tiroir et le boîtier par tout moyen connu.Finally, the clip and the latch can respectively be positioned and held firmly in the drawer and the housing by any known means.

Evidemment, l'invention trouve son application dans tous genres d'industries où des conducteurs sont à connecter, comme par exemple les industries aérospatiale et téléphonique.Obviously, the invention finds its application in all kinds of industries where conductors are to be connected, such as for example the aerospace and telephone industries.
