Description

La présente invention se rapporte à un dispositif de connexion d'extrémité libres de fils électriques par utilisation de contacts métalliques à au moins une fente autodénudante.The present invention relates to a connection device free end of electrical wires by using metal contacts at minus an insulation displacement slot.

La technique de connexion, en particulier de lignes téléphoniques, par la technique des contacts métalliques à fente autodénudante est maintenant largement répandue dans cette technique très spécialisée.The technique of connection, in particular of telephone lines, by the technique of metal contacts with insulation displacement gap is now widely used in this very specialized technique.

A ce titre, le document EP-A-0.585.179 décrit une prise femelle de type « modular jack » et à connectique intégrée, pour laquelle les contacts modular jack sont repris, à l'arrière de la prise, sur des contacts à fentes autodénudantes. La connexion d'un fil téléphonique à l'arrière de la prise s'effectue, sans outil spécifique, par fermeture d'un chapeau rotatif qui est associé à ces contacts autodénudants et qui sert de poussoir de connexion.As such, document EP-A-0.585.179 describes a female socket of “modular jack” type and with integrated connectors, for which the modular contacts jack are taken, at the back of the socket, on contacts with insulation displacement slits. The connection of a telephone wire to the rear of the socket is done without tools specific, by closing a rotating cap which is associated with these contacts insulation displacement and which serves as a connection pusher.

Ces dispositifs connus présentent les inconvénients suivants :

  • L'opération de connexion d'un fil est peu commode à réaliser, du fait que l'opérateur doit tenir le fil d'une main pour bien le positionner à l'entrée de la fente autodénudante pendant qu'il utilise l'autre main pour fermer le chapeau de connexion rotatif
  • une fois la connexion réalisée, tous les efforts extérieurs qui s'exercent sur le fil, par exemple lors de l'insertion de la prise dans un réceptacle encastré ou non, sont appliqués sur le contact autodénudant et il y a alors un risque non négligeable de déconnexion accidentelle ou de rupture de ce fil.
These known devices have the following drawbacks:
  • The operation of connecting a wire is awkward to carry out, since the operator must hold the wire with one hand to properly position it at the entrance to the insulation displacement slot while using the other hand. to close the rotary connection cap
  • once the connection has been made, all the external forces exerted on the wire, for example when inserting the plug into a receptacle, whether embedded or not, are applied to the insulation displacement contact and there is then a considerable risk accidental disconnection or breakage of this wire.

Le document EP-A-0.671.780 décrit un dispositif de connexion du type concerné par la présente invention, pour lequel deux picots sont prévus en avant de chaque contact autodénudant pour maintenir le fil dans une direction bien droite et orthogonale à la fente autodénudante. Cette solution est cependant insuffisante pour pallier efficacement les inconvénients précités. The document EP-A-0.671.780 describes a device for connecting the type concerned by the present invention, for which two pins are provided in before each insulation displacement contact to keep the wire in a good direction straight and orthogonal to the insulation displacement slit. This solution is however insufficient to effectively overcome the aforementioned drawbacks.

L'invention vise à remédier à ces inconvénients. Elle se rapporte à cet effet à un dispositif de connexion d'extrémités libres de fils, par utilisation de contacts métalliques à chacun au moins une fente autodénudante, ce dispositif comportant au moins un chapeau rotatif qui se referme en tournant autour d'une ligne de pivotement et qui vient alors recouvrir un ou plusieurs contacts autodénudants en jouant le rôle de poussoir de connexion des fils dans ces contacts autodénudants,
   caractérisé :

  • en ce qu'il comporte, près de chaque fente autodénudante, une petite rainure de maintien du fil dans laquelle ce dernier peut être introduit afin de le maintenir en place dans ladite fente pour l'actionnement dudit chapeau mobile, cette rainure étant parallèle à cette fente autodénudante,
  • en ce qu'il comporte en outre, derrière chaque fente autodénudante, une butée de réception et de maintien de l'extrémité libre du fil à connecter.
  • et en ce que ledit chapeau rotatif comporte en outre un ou des organes de fermeture de chacune de ces petites rainures de maintien qui sont mis en place lorsque ce chapeau rotatif est en position de fermeture totale et qui, en coopération avec la rainure associée, maintiennent fermement le fil et reprennent pratiquement alors les forces extérieures de traction ou de compression qui peuvent par la suite s'exercer sur ce fil.
The invention aims to remedy these drawbacks. To this end, it relates to a device for connecting free ends of wires, by using metal contacts to each at least one insulation displacement slot, this device comprising at least one rotating cap which closes by turning around a line of pivoting and which then covers one or more insulation displacement contacts by playing the role of push-button for connecting the wires in these insulation displacement contacts,
characterized:
  • in that it comprises, near each insulation displacement slot, a small groove for holding the wire into which the latter can be introduced in order to hold it in place in said slot for actuation of said movable cap, this groove being parallel to this insulation displacement slot,
  • in that it further comprises, behind each insulation displacement slot, a stop for receiving and holding the free end of the wire to be connected.
  • and in that said rotary cap further comprises one or more closing members for each of these small retaining grooves which are put in place when this rotary cap is in the fully closed position and which, in cooperation with the associated groove, maintain firmly the wire and practically resume the external forces of traction or compression which can subsequently be exerted on this wire.

Avantageusement, chaque organe de fermeture est constitué par au moins un petit couvercle, solidaire du chapeau rotatif, qui vient, en position de fermeture du chapeau, s'adapter sur au moins une rainure pour fermer celle-ci en enserrant étroitement le fil. Selon une forme de réalisation, ce couvercle est prévu pour venir refermer simultanément deux rainures adjacentes.Advantageously, each closure member is constituted by at minus a small cover, integral with the rotating cap, which comes in the position of closure of the hat, fit on at least one groove to close it in tightly wrapping the wire. According to one embodiment, this cover is provided to close two adjacent grooves simultaneously.

Préférentiellement aussi, le chapeau de fermeture présente au moins un organe de verrouillage en sa position de fermeture, de sorte que cet organe de verrouillage vient maintenir fermement chaque couvercle sur la rainure de maintien qu'il vient refermer.Also preferably, the closure cap has at least one locking member in its closed position, so that this locking device firmly holds each cover on the retaining groove that it comes to close.

L'invention sera bien comprise et ses avantages et autres caractéristiques ressortiront mieux, lors de la description suivante d'un exemple non limitatif de réalisation, en référence au dessin schématique annexé dans lequel :

  • Figure 1 est une vue en perspective de la partie arrière d'une prise « modular jack » monopaire, cette partie arrière constituant un dispositif de connexion, par contacts autodénudants, d'une ligne téléphonique ou informatique, un fil étant ici mis en place pour être connecté, et le poussoir de connexion étant en position ouverte.
  • Figure 2 est une vue en coupe longitudinale partielle, selon II-II de Figure 3, qui montre ce même dispositif avec le poussoir basculant fermé et le fil connecté.
  • Figure 3 est une vue en coupe horizontale selon III-III de Figure 2.
The invention will be clearly understood and its advantages and other characteristics will emerge more clearly from the following description of a nonlimiting exemplary embodiment, with reference to the appended schematic drawing in which:
  • Figure 1 is a perspective view of the rear part of a single jack “modular jack”, this rear part constituting a connection device, by insulation-displacement contacts, of a telephone or computer line, a wire being placed here for be connected, and the connection button being in the open position.
  • Figure 2 is a partial longitudinal sectional view, along line II-II of Figure 3, which shows this same device with the tilting pusher closed and the wire connected.
  • Figure 3 is a horizontal sectional view along III-III of Figure 2.

La figure 1 montre la partie arrière d'une prise « modular jack » monopaire. Cette prise comporte deux contacts métalliques autodénudants 1, 2 qui, dans cet exemple de réalisation, comportent chacun deux fentes autodénudantes, comme c'est le cas pour ceux décrits dans le document EP-A-0.585.179 précité.Figure 1 shows the rear part of a modular jack single-pair. This socket has two metal insulation-displacement contacts 1, 2 which, in this exemplary embodiment, each have two slots insulation displacement, as is the case for those described in document EP-A-0.585.179 supra.

Comme on le voit mieux sur la figure 2, ces deux contacts métalliques autodénudants 1, 2 sont chacun constitués de deux épaisseurs métalliques et sont maintenus dans le corps plastique arrière 3 de la prise.As best seen in Figure 2, these two metal contacts insulation displacement 1, 2 each consist of two metallic thicknesses and are held in the rear plastic body 3 of the socket.

Cette prise possède, à l'instar de celle selon le document EP-A-0.585.179, un poussoir de connexion rotatif 4 en matière plastique qui est réalisé sous la forme d'un couvercle ou chapeau basculant, la rotation de ce poussoir 4 s'effectuant autour d'un axe ou ligne de pivotement 5 qui est parallèle à la rangée de contacts autodénudants 1, 2.This socket has, like that according to the document EP-A-0.585.179, a rotary connection pusher 4 made of plastic material which is produced in the form of a tilting cover or cap, the rotation of this pusher 4 taking place around an axis or pivot line 5 which is parallel to the row of insulation displacement contacts 1, 2.

Sur la figure 1, on distingue nettement les deux couples de lames-poussoir 61, 62 et 63, 64 qui vont venir chasser, lorsque l'on va refermer le chapeau basculant, les fils à connecter dans leurs fentes autodénudantes réceptrices, respectivement du contact métallique 1 et du contact métallique 2.In FIG. 1, the two pairs of push-buttons are clearly distinguished 61, 62 and 63, 64 which will come to hunt, when we are going to close the tilting cap, the wires to be connected in their insulation-displacement slots receptacles, of metallic contact 1 and metallic contact 2 respectively.

A titre illustratif, la figure 1 montre un fil téléphonique gainé 6 qui est mis en place dans le contact 1, à l'entrée de sa deuxième fente autodénudante et qui est donc prêt à être connecté par fermeture du poussoir de connexion rotatif 4.By way of illustration, FIG. 1 shows a sheathed telephone wire 6 which is placed in contact 1, at the entrance to its second insulation displacement slot and which is therefore ready to be connected by closing the rotary connection button 4.

Le chapeau basculant, ou poussoir rotatif, 4 comporte un cliquet élastique 7 de verrouillage par encliquetage en fin de course, ce cliquet 7 coopérant avec une butée fixe 8 de verrouillage par encliquetage en fin de course. Cette butée 8 est formée par un bec en matière plastique qui fait partie du corps 3 et qui est obtenu de moulage avec ce dernier.The tilting cap, or rotary pusher, 4 comprises a pawl elastic 7 for locking by snap-fastening at the end of travel, this pawl 7 cooperating with a fixed stop 8 for snap locking at the end of the stroke. This stop 8 is formed by a plastic spout which is part of the body 3 and which is obtained from molding with the latter.

Conformément à l'invention, il est prévu, de moulage ici avec le corps plastique 3, des petites rainures de maintien 11, 12, 21, 22 des fils respectifs 6 à connecter.According to the invention, there is provision for molding here with the body. plastic 3, small holding grooves 11, 12, 21, 22 of the respective wires 6 to Connect.

Ces rainures de maintien, 11, 12, 21, 22, dont la section est également bien visible sur la figure 3, sont chacune placées à proximité immédiate d'une des fentes autodénudantes, respectivement (figure 3) 13, 14, 23, 24. Plus précisément d'ailleurs, elles sont placées chacune sous sa fente autodénudante respective et un peu en avant (dans le sens droite-gauche sur les figures) de cette fente.These retaining grooves, 11, 12, 21, 22, the section of which is also clearly visible in Figure 3, are each placed in the immediate vicinity of one of the insulation displacement slots, respectively (Figure 3) 13, 14, 23, 24. More specifically moreover, they are each placed under its respective insulation displacement slot and a slightly forward (in the right-left direction in the figures) of this slot.

la section de ces rainures de maintien est adaptée (voir figure 3) au diamètre du fil 6, de manière à légèrement coincer celui-ci lorsqu'il est introduit (figures 1 et 3) dans une de ces rainures.the section of these retaining grooves is adapted (see FIG. 3) to diameter of the wire 6, so as to slightly jam it when it is introduced (Figures 1 and 3) in one of these grooves.

Ces rainures permettent, en premier lieu et comme schématisé sur la figure 1, de maintenir le fil 6 en place dans sa fente autodénudante respective 14 avant que l'on actionne le poussoir rotatif 4 pour chasser ce fil dans cette fente et réaliser alors la connexion autodénudante.These grooves allow, first and as shown schematically on the Figure 1, to maintain the wire 6 in place in its respective insulation displacement slot 14 before the rotary pusher 4 is actuated to drive this wire into this slot and then make the insulation displacement connection.

Cette mise en place est d'ailleurs avantageusement facilitée par le fait qu'il est prévu, à l'arrière de chaque fente autodénudante, une butée ou demi-cavité semi-circulaire de réception et de maintien de l'extrémité libre du fil 6, respectivement 91à 94 pour les fentes 12, 14, 23, 24.This implementation is also advantageously facilitated by the fact that there is provided, at the rear of each insulation displacement slot, a stop or half-cavity semi-circular for receiving and holding the free end of the wire 6, respectively 91 to 94 for slots 12, 14, 23, 24.

Ces demi-cavités de maintien sont formées dans une pièce plastique transversale 9 possédant des arches 91 à 94 en demi-cercle, à la manière d'un pont. En variante, cette pièce plastique pourrait comporter des cavités complètes, ou puits, de section circulaire et adaptée à celle des fils 6 de façon à recevoir l'extrémité libre de chacun d'eux.These retaining half-cavities are formed in a plastic part transverse 9 having arches 91 to 94 in a semicircle, like a bridge. As a variant, this plastic part could include complete cavities, or well, of circular section and adapted to that of the wires 6 so as to receive the free end of each of them.

Une fois le fil 6 mis en place, selon Figure 1, dans sa demi-cavité réceptrice 92, dans le « Vé » d'entrée de sa fente autodénudante respective 14 et dans sa rainure de maintien 12, ce fil tient suffisamment bien en place pour qu'on puisse le lâcher, ce qui libère une main pour pouvoir alors aisément actionner le poussoir rotatif 4.Once the wire 6 is in place, according to Figure 1, in its half-cavity receiver 92, in the entry “V” of its respective insulation displacement slot 14 and in its retaining groove 12, this wire holds sufficiently well in place so that can release it, which frees a hand so that you can easily activate the rotary pushbutton 4.

En outre, le chapeau de fermeture 4 comporte sur sa face interne (voir figures 1 et 3) des petites nervures intérieures 15, 16 qui sont agencées (figure 3) pour venir respectivement fermer les couples de rainures 11, 12 et 21, 22 lorsque le chapeau 4 est fermé et verrouillé comme montré en figure 2. Ces nervures 15, 16 jouent donc le rôle d'un couvercle de fermeture pour chacun de ces deux couples de rainures. Ici, une seule nervure, 15 par exemple, vient fermer deux rainures adjacentes à la fois, 11 et 12. En variante, on pourrait prévoir une nervure respective pour fermer chaque rainure séparément.In addition, the closure cap 4 has on its internal face (see Figures 1 and 3) small internal ribs 15, 16 which are arranged (Figure 3) to come respectively to close the pairs of grooves 11, 12 and 21, 22 when the cap 4 is closed and locked as shown in FIG. 2. These ribs 15, 16 therefore play the role of a closure cover for each of these two couples grooves. Here, a single rib, for example 15, closes two grooves adjacent to both, 11 and 12. Alternatively, a rib could be provided respective to close each groove separately.

Lorsque finalement le chapeau basculant est fermé et verrouillé, selon Figures 2 et 3, le fil 6 est descendu, poussé par sa lame-poussoir respective 62, dans sa fente autodénudante 14. Il est donc dénudé et connecté. En outre, il est maintenu fermement dans sa rainure de maintien 12 par le fait que le couvercle de fermeture 15 de cette rainure est solidement verrouillé par l'effet du dispositif de verrouillage 7, 8. Toutes les sollicitations extérieures qui peuvent s'exercer, en particulier lors de la mise en place de la prise dans sa cavité d'encastrement, sur le fil 6 sont alors reprises par la rainure de maintien 12 et ne sont pratiquement donc pas transmises à la fente autodénudante 14.When the tilting cap is finally closed and locked, according to Figures 2 and 3, the wire 6 is lowered, pushed by its respective push-blade 62, in its insulation displacement slot 14. It is therefore stripped and connected. In addition, it is held firmly in its retaining groove 12 by the fact that the cover closure 15 of this groove is securely locked by the effect of the locking 7, 8. All external stresses which may be exerted, in particular particularly when installing the socket in its recess, on the wire 6 are then taken up by the retaining groove 12 and are therefore practically not transmitted to the insulation displacement slot 14.

Comme il va de soi, l'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit. C'est ainsi par exemple que les contacts métalliques autodénudants peuvent être chacun constitués d'une seule épaisseur métallique au lieu de deux. Elle s'applique aussi bien en particulier aux prises modular-jack pour lignes multiples ainsi qu'aux poussoirs rotatifs de connexion multiples. L'axe 5 pourrait être remplacé par un dispositif de charnière équivalent : par exemple, le chapeau 4 pourrait être relié au corps 3 par une languette souple ne matière plastique. L'invention s'applique au domaine de la connectique en général, et non pas seulement à celui de la connectique téléphonique ou informatique.It goes without saying that the invention is not limited to the example of realization which has just been described. For example, contacts insulating metal may each consist of a single thickness metallic instead of two. It applies equally well in particular to sockets modular-jack for multiple lines as well as rotary connection pushers multiple. Axis 5 could be replaced by an equivalent hinge device: for example, the cap 4 could be connected to the body 3 by a flexible tongue not plastic material. The invention applies to the field of connectors in general, and not just that of telephone or computer connections.
