Description

La présente invention concerne un connecteur mâle pour réseau de communication informatique et/ou téléphonique.The present invention relates to a male connector for a computer and / or telephone communication network.

Elle s'applique notamment au réseau de transmission utilisant des câbles multilignes tels que par exemple des réseaux locaux ou non, qui permettent des transmissions de données informatiques (les réseaux connus par exemple sous les dénominations STARLAN, ETHERNET, TOKEN RING, etc....) ou des transmissions de données téléphoniques numériques (par exemple le réseau RNIS ou réseau numérique à intégration de service). On sait qu'il est indispensable de pouvoir raccorder en dérivation et/ou en série sur chaque réseau et de façon simple, un ou plusieurs équipements terminaux de traitement de données (en abrégé ETTD), informatiques et/ou téléphoniques, selon le type de réseau considéré. Ces équipements terminaux de traitement de données sont aussi appelés "Data Terminal Equipment" en anglais (ou en abrégé DTE), ou encore terminal ou encore station.It applies in particular to the transmission network using multiline cables such as for example local networks or not, which allow computer data transmissions (the networks known for example under the names STARLAN, ETHERNET, TOKEN RING, etc ... .) or digital telephone data transmissions (for example the ISDN network or integrated service digital network). We know that it is essential to be able to connect in branch and / or in series on each network and in a simple way, one or more terminal data processing equipment (abbreviated as DTE), computer and / or telephone, depending on the type of network considered. These terminal data processing equipment are also called "Data Terminal Equipment" in English (or abbreviated to DTE), or even terminal or station.

Un connecteur mâle, qui permet de relier grâce à des lignes d'un câble de communication un terminal informatique et/ou téléphonique à un réseau, par insertion de ce connecteur mâle dans un connecteur femelle ayant des bornes de connexion reliées à ce réseau, est décrit par exemple dans la demande de brevet européen N° 0366556 déposée le 26 octobre 1989.A male connector, which makes it possible to connect, by means of lines of a communication cable, a computer and / or telephone terminal to a network, by inserting this male connector into a female connector having connection terminals connected to this network, is described for example in European patent application No. 0366556 filed October 26, 1989.

Cette demande de brevet décrit plus précisément un ensemble universel de connexion pour raccorder un terminal de traitement à un réseau de transmission de données. Cet ensemble universel comporte un connecteur mâle et un connecteur femelle ; le connecteur mâle comporte notamment un support isolant parallélépipédique ayant deux faces latérales, une face supérieure, une face inférieure, une face avant et une face arrière, et des bornes de connexion partiellement noyées dans le support et débouchant sur l'une des faces supérieure ou inférieure. Ces bornes sont reliées à des lignes d'un câble de communication entouré d'une gaine isolante et entrant dans le support par sa face arrière. Les bornes de connexion du connecteur mâle entrent respectivement en contact par glissement avec des bornes correspondantes d'un connecteur femelle ; ces bornes du connecteur femelle sont situées dans un boîtier et sont respectivement reliées à des lignes d'un réseau de communication. Les contacts entre les bornes du connecteur mâle et du connecteur femelle s'établissent lors de l'insertion du connecteur mâle dans une fenêtre d'entrée découpant une face avant du boîtier du conducteur femelle. Cette fenêtre d'entrée présente des bords qui sont respectivement parallèles aux faces du support isolant du connecteur mâle.This patent application describes more precisely a universal connection assembly for connecting a processing terminal to a data transmission network. This universal set has a male connector and a female connector; the male connector comprises in particular a parallelepipedal insulating support having two lateral faces, an upper face, a lower face, a front face and a rear face, and connection terminals partially embedded in the support and opening onto one of the upper faces or lower. These terminals are connected to lines of a communication cable surrounded by an insulating sheath and entering the support by its rear face. The connection terminals of the male connector respectively come into sliding contact with corresponding terminals of a female connector; these terminals of the female connector are located in a housing and are respectively connected to lines of a communication network. The contacts between the terminals of the male connector and the female connector are established when the male connector is inserted into an entry window cutting out a front face of the female conductor housing. This entry window has edges which are respectively parallel to the faces of the insulating support of the male connector.

Le support isolant du connecteur mâle décrit dans cette demande de brevet comporte en outre une languette élastique rigide, rendue solidaire du support au voisinage d'une face voisine de la face avant du connecteur, opposée à la face par laquelle débouchent les bornes de connexion du connecteur mâle. Cette languette est rendue solidaire de ce support par une embase plane, plus large que la languette. Cette languette et cette embase sont inclinées et s'engagent dans une découpe correspondante de la face avant du boîtier, adjacente à la fenêtre d'insertion. L'embase qui relie la languette au support comporte un épaulement transversal de verrouillage, de sorte qu'au cours de l'insertion du connecteur mâle dans le connecteur femelle la languette et l'embase se rabattent progressivement vers la face inférieure du support, par appui et glissement de cette embase sur les bords de la découpe adjacente à la fenêtre du boîtier. A la fin de l'insertion, la languette et l'embase s'éloignent du support pour verrouiller la position du connecteur mâle, par appui de l'épaulement de l'embase sur une paroi interne de la face avant du boîtier. Une portion de la languette reste accessible à l'extérieur du boîtier.The insulating support of the male connector described in this patent application further comprises a rigid elastic tongue, made integral with the support in the vicinity of a face close to the front face of the connector, opposite the face through which the connection terminals of the male connector. This tongue is made integral with this support by a flat base, wider than the tongue. This tab and this base are inclined and engage in a corresponding cutout of the front face of the housing, adjacent to the insertion window. The base which connects the tongue to the support has a transverse locking shoulder, so that at the during the insertion of the male connector into the female connector, the tab and the base gradually fold down towards the underside of the support, by pressing and sliding this base on the edges of the cutout adjacent to the window of the housing. At the end of the insertion, the tongue and the base move away from the support to lock the position of the male connector, by pressing the shoulder of the base on an internal wall of the front face of the housing. A portion of the tongue remains accessible outside the housing.

Les connecteurs mâles de ce type ont pour avantage essentiel d'être de format très réduit et d'assurer un bon verrouillage de la position du connecteur mâle dans le connecteur femelle. Cet avantage peut devenir un inconvénient, par exemple lorsque le câble relié au connecteur mâle subit une traction intempestive, lorsqu'une personne évoluant au voisinage de ce câble accroche celui-ci par mégarde, entraînant ainsi la chute probable de l'appareil ou du terminal relié à ce câble et des risques importants d'arrachement de la prise femelle.The main advantage of male connectors of this type is that they are very small in size and ensure good locking of the position of the male connector in the female connector. This advantage can become a disadvantage, for example when the cable connected to the male connector undergoes untimely traction, when a person moving in the vicinity of this cable catches it inadvertently, thus causing the probable fall of the device or the terminal. connected to this cable and significant risk of the socket being torn off.

L'invention a pour but de remédier à cet inconvénient et notamment de fournir un connecteur mâle pour réseau de communication informatique et/ou téléphonique, de type décrit plus haut, qui permet en cas de traction intempestive sur le câble qui relie le connecteur mâle à un appareil, lorsque ce connecteur est engagé dans le connecteur femelle, de faciliter sa déconnexion sans risque de chute de l'appareil et du terminal relié au câble, et sans risque d'arrachement de la prise femelle.The invention aims to remedy this drawback and in particular to provide a male connector for computer and / or telephone communication network, of the type described above, which allows in the event of untimely pulling on the cable which connects the male connector to a device, when this connector is engaged in the female connector, to facilitate its disconnection without risk of falling of the device and of the terminal connected to the cable, and without risk of tearing of the female socket.

Le connecteur mâle pour réseau de communication informatique et/ou téléphonique de l'invention est représenté schématiquement et en perspective sur la figure 1. Ce connecteur comporte un support isolant parallélépipédique 1 ayant deux faces latérales 2, 3, une face supérieure 4, une face inférieure 5, ainsi qu'une face avant 6 et une face arrière 7. Comme on le verra plus loin en détail à l'aide de la figure 5, des bornes de connexion 8 sont partiellement noyées dans le support 1 et débouchent sur la face supérieure 4 du support. Ces bornes sont reliées à des lignes 9 d'un câble de communication 10 entourées d'une gaine isolante 11 et entrant dans le support 1 par sa face arrière 7. Comme on le verra plus loin en détail, une portion de la gaine 11 du câble 10, voisine de la face arrière 7 du support 1, comporte des moyens 39 pour courber le câble et la gaine qui l'entoure, vers la face inférieure 5 du support. Ces moyens 39 peuvent être constitués par des rainures réalisées dans une surépaisseur de la gaine 11, au voisinage du support 1, provoquant un effet de rappel du câble et de sa gaine, vers la face inférieure 5 du support 1.The male connector for a computer and / or telephone communication network of the invention is shown schematically and in perspective in FIG. 1. This connector comprises a rectangular insulating support 1 having two lateral faces 2, 3, an upper face 4, a face lower 5, as well as a front face 6 and a rear face 7. As will be seen below in detail using FIG. 5, connection terminals 8 are partially embedded in the support 1 and open onto the face upper 4 of the support. These terminals are connected to lines 9 of a communication cable 10 surrounded by an insulating sheath 11 and entering the support 1 by its rear face 7. As will be seen below in detail, a portion of the sheath 11 of the cable 10, adjacent to the rear face 7 of the support 1, comprises means 39 for bending the cable and the sheath which surrounds it, towards the lower face 5 of the support. These means 39 may be constituted by grooves made in an extra thickness of the sheath 11, in the vicinity of the support 1, causing a return effect of the cable and its sheath, towards the lower face 5 of the support 1.

Les bornes de connexion 8 du connecteur mâle entrent respectivement en contact par glissement avec des bornes correspondantes d'un connecteur femelle. Ce connecteur femelle est représenté schématiquement et en perspective sur la figure 2. Les bornes du connecteur femelle, non représentées sur cette figure, sont enfermées dans un boîtier 12 et sont respectivement reliées à des lignes du réseau de communication. Le boîtier 12 du connecteur femelle présente une fenêtre d'entrée 13 qui découpe une face avant 14 de ce boîtier. Cette fenêtre d'entrée permet l'insertion du connecteur mâle dans le connecteur femelle ; elle présente des bords 15, 16, 17, 18, respectivement parallèles aux faces supérieure, inférieure et latérales 4, 5, 2, 3 du support.The connection terminals 8 of the male connector respectively come into sliding contact with corresponding terminals of a female connector. This female connector is shown schematically and in perspective in Figure 2. The terminals of the female connector, not shown in this figure, are enclosed in a housing 12 and are respectively connected to lines of the communication network. The housing 12 of the female connector has an inlet window 13 which cuts a front face 14 of this housing. This input window allows the insertion of the male connector into the female connector; it has edges 15, 16, 17, 18, respectively parallel to the upper, lower and lateral faces 4, 5, 2, 3 of the support.

Le support 1 représenté sur la figure 1 comporte aussi une languette élastique rigide 19, rendue solidaire de ce support, au voisinage de ses faces inférieure et avant 5, 6, par une embase 20 plus large que la languette 19. Cette languette et cette embase sont inclinées par rapport à la face inférieure 5 du support et s'engagent dans une découpe correspondante 21 (figure 2) de la face avant 14 du boîtier 12. Cette découpe est adjacente à la fenêtre 13. L'embase 20 comporte un épaulement transversal de verrouillage 22. Pour faciliter l'insertion du connecteur mâle dans le connecteur femelle, l'embase 20 et l'épaulement 22 peuvent être reliés par une surface inclinée 40. L'épaulement 22 est lui aussi de préférence incliné, comme représenté sur la figure.The support 1 shown in FIG. 1 also includes a rigid elastic tongue 19, made integral with this support, in the vicinity of its lower and front faces 5, 6, by a base 20 wider than the tongue 19. This tongue and this base are inclined relative to the lower face 5 of the support and engage in a corresponding cutout 21 (FIG. 2) of the front face 14 of the housing 12. This cutout is adjacent to the window 13. The base 20 has a transverse shoulder Locking 22. To facilitate insertion of the male connector into the female connector, the base 20 and the shoulder 22 can be connected by an inclined surface 40. The shoulder 22 is also preferably inclined, as shown in the figure.

Au cours de l'insertion du connecteur mâle dans la fenêtre 13 du connecteur femelle, la languette 19 et l'embase 20 se rabattent progressivement vers la face inférieure 5 du support 1 par appui et glissement de cette embase et de la surface inclinée 40, sur les bords de la découpe 21. A la fin de l'insertion, la languette et l'embase s'éloignent de la face inférieure du support pour verrouiller la position du connecteur mâle par appui de l'épaulement 22 sur une paroi interne de la face avant 14 du boîtier 12. Cette paroi interne est visible en 23 sur la figure 3.During the insertion of the male connector into the window 13 of the female connector, the tongue 19 and the base 20 are gradually folded down towards the lower face 5 of the support 1 by pressing and sliding this base and the inclined surface 40, on the edges of the cutout 21. At the end of the insertion, the tongue and the base move away from the underside of the support to lock the position of the male connector by pressing the shoulder 22 on an internal wall of the front face 14 of the housing 12. This internal wall is visible at 23 in FIG. 3.

Comme le montre la figure 3, une portion de la languette 19 est accessible à l'extérieur du boîtier 12.As shown in FIG. 3, a portion of the tongue 19 is accessible outside the housing 12.

Selon l'invention et comme le montre la figure 1, le connecteur mâle comporte du côté de la face inférieure 5 du support 1, une targette 24 glissant le long de cette face inférieure 5, entre les faces avant 6 et arrière 7 du support ; cette targette s'engage sous la portion de languette 19 qui reste extérieure à la face avant 14 du boîtier 12 du connecteur femelle lorsque le connecteur mâle est complètement inséré dans ce connecteur femelle, comme le montre la figure 3.According to the invention and as shown in FIG. 1, the male connector comprises, on the side of the lower face 5 of the support 1, a pin 24 sliding along this lower face 5, between the front 6 and rear 7 faces of the support; this bolt engages under the tongue portion 19 which remains outside the front face 14 of the housing 12 of the female connector when the male connector is completely inserted in this female connector, as shown in FIG. 3.

Comme représenté sur la figure 1, la targette 24 est munie de moyens élastiques de rappel 25, 26, s'appuyant sur un moyen de guidage 27 du support 1, pour provoquer un mouvement de rappel de cette targette vers la face avant 6 du support, lorsque la targette a été tirée vers la face arrière 7. Cette targette est aussi reliée par des moyens articulés 28, 29, à la gaine 11 du câble 10. Les moyens articulés peuvent être constitués par exemple par un anneau 28 solidaire de la targette 24 et par un crochet 29 solidaire de la gaine 11 du câble 10. Les moyens élastiques sont constitués par deux glissières élastiques 25, 26. Le moyen de guidage 27 peut être constitué par un axe fendu. Lorsque la targette est tirée vers la face arrière 7 du support 1, les glissières élastiques 25, 26, s'écartent. Au contraire, l'élasticité des glissières 25, 26, ainsi que l'élasticité de l'axe fendu 27 et l'action des moyens 39 de courbure du câble, permettent la sollicitation de la targette 24 vers la face avant 6 du support 1 : la targette s'engage alors, comme représenté sur la figure 3, sous la languette 19.As shown in FIG. 1, the bolt 24 is provided with elastic return means 25, 26, resting on a guide means 27 of the support 1, to cause a return movement of this bolt towards the front face 6 of the support , when the bolt has been pulled towards the rear face 7. This targette is also connected by articulated means 28, 29, to the sheath 11 of the cable 10. The articulated means can be constituted for example by a ring 28 secured to the targette 24 and by a hook 29 secured to the sheath 11 of the cable 10 The elastic means consist of two elastic slides 25, 26. The guide means 27 can consist of a split axis. When the bolt is pulled towards the rear face 7 of the support 1, the elastic slides 25, 26, move apart. On the contrary, the elasticity of the slides 25, 26, as well as the elasticity of the split axis 27 and the action of the means 39 for bending the cable, allow the loading of the pin 24 towards the front face 6 of the support 1 : the targette then engages, as shown in FIG. 3, under the tongue 19.

La targette 24 est tirée vers la face arrière 7 du support 1, par exemple par traction du doigt d'un opérateur sur le renflement 30. Lorsque l'insertion est complète, l'épaulement 22 vient s'appuyer sur le bord 23 de la paroi interne du boîtier 12 ; la targette 1 peut alors être relâchée de sorte que les moyens élastiques 25, 26, ramènent celle-ci vers la face avant 6 du support 1 et que l'extrémité 31 s'engage sous la languette 19. On a aussi représenté sur la figure 3, de manière schématique, l'une des bornes de connexion 32 du connecteur femelle, contenue dans le boîtier 12, ainsi que l'une des bornes de connexion 8 du connecteur mâle.The bolt 24 is pulled towards the rear face 7 of the support 1, for example by pulling the finger of an operator on the bulge 30. When the insertion is complete, the shoulder 22 comes to bear on the edge 23 of the inner wall of the housing 12; the bolt 1 can then be released so that the elastic means 25, 26, bring the latter towards the front face 6 of the support 1 and that the end 31 engages under the tongue 19. Also shown in the figure 3, schematically, one of the connection terminals 32 of the female connector, contained in the housing 12, as well as one of the connection terminals 8 of the male connector.

Lorsque le connecteur mâle est inséré dans le connecteur femelle, les moyens de courbure 39 du câble, maintiennent la targette dans une position de repos : l'extrémité 31 de la targette est engagée sous la languette 19.When the male connector is inserted into the female connector, the bending means 39 of the cable keep the bolt in a rest position: the end 31 of the bolt is engaged under the tongue 19.

Après insertion et tel que représenté sur la figure 4, lorsqu'une traction ( figurée par la flèche 33) est exercée sur le câble 10, la targette se déplace vers la face arrière 7 du support 1 comme l'indique la flèche 34, grâce à l'action des moyens articulés 28, 29. Le mouvement vers l'arrière de la targette libère alors la languette 19 qui peut se rabattre vers ta face inférieure 5 du support 1. La position verrouillée du connecteur mâle dans le connecteur femelle, qui était maintenue grâce à l'épaulement 22 sur la paroi 23, est alors libérée. La surface inclinée 40 favorise la libération de cette position verrouillée. Il en résulte que la déconnexion du connecteur mâle et du connecteur femelle est alors facilitée, évitant ainsi la chute de l'appareil relié au câble 10 ou l'arrachement du boîtier 12 du connecteur femelle.After insertion and as shown in FIG. 4, when a pull (represented by arrow 33) is exerted on the cable 10, the bolt moves towards the rear face 7 of the support 1 as indicated by arrow 34, thanks to the action of the articulated means 28, 29. The rearward movement of the bolt then releases the tongue 19 which can be folded towards the lower face 5 of the support 1. The locked position of the male connector in the female connector, which was maintained by the shoulder 22 on the wall 23, is then released. The inclined surface 40 promotes the release of this locked position. It follows that the disconnection of the male connector and the female connector is then facilitated, thus avoiding the fall of the device connected to the cable 10 or the tearing of the housing 12 of the female connector.

La figure 5 représente schématiquement et en coupe longitudinale le connecteur mâle de l'invention. On distingue sur cette figure l'une des bornes de connexion 8 de ce connecteur, noyée dans le support isolant 1. Le connecteur comporte un cavalier 35 en matière isolante par exemple, qui vient ensérrer le support 1, au voisinage de la face arrière 7 de ce support. Ce cavalier recouvre partiellement les faces latérales 2, 3 et la face supérieure 4 du support, pour appuyer sur l'extrémité 36 de chaque ligne 9 du câble de communication 10; présente à l'intérieur du support 1 ; cet appui permet d'assurer les contacts respectifs entre les extrémités des lignes et les bornes correspondantes du connecteur mâle. Chaque borne de connexion 8 présente, du côté de la face arrière 7 du support 1, une forme en pointe par exemple, permettant grâce à l'appui du cavalier 35 sur la ligne 9, de perforer l'isolant entourant cette ligne jusqu'au conducteur entouré par cet isolant ; la borne et le conducteur de la ligne sont alors en contact. Le cavalier 5 est maintenu sur le support 1 par exemple grâce à des lumières 37 réalisées sur les faces latérales de ce cavalier et qui s'engagent sur des bossages 38 présents sur les faces latérales du support 1. Le cavalier 35 assure un blocage efficace des lignes 9 du câble 10.Figure 5 shows schematically and in longitudinal section the male connector of the invention. We distinguish in this figure one of the connection terminals 8 of this connector, embedded in the insulating support 1. The connector comprises a jumper 35 of insulating material for example, which comes to surround the support 1, in the vicinity of the rear face 7 of this support. This jumper partially covers the side faces 2, 3 and the upper face 4 of the support, in order to press on the end 36 of each line 9 of the communication cable 10; present inside the support 1; this support ensures the respective contacts between the ends of the lines and the corresponding terminals of the male connector. Each connection terminal 8 has, on the side of the rear face 7 of the support 1, a pointed shape for example, allowing, by means of the support of the jumper 35 on the line 9, to perforate the surrounding insulation this line to the conductor surrounded by this insulator; the terminal and the line conductor are then in contact. The jumper 5 is held on the support 1 for example by means of lights 37 made on the lateral faces of this jumper and which engage on bosses 38 present on the lateral faces of the support 1. The jumper 35 ensures effective blocking of the lines 9 of cable 10.

Les faces latérales du support 1 sont au moins partiellement métallisées au voisinage des contacts respectifs entre les bornes de connexion 8 et les extrémités 36 des lignes du câble, pour former un fourreau de blindage qui est relié à une gaine métallique de blindage du câble (non représentée sur cette figure). Ce blindage est apte à entrer en contact avec un fourreau de blindage entourant les bornes du conducteur femelle, à l'intérieur du boîtier 12. Ce blindage du connecteur femelle (non représenté sur les figures) est lui-même relié à un fourreau de blindage des lignes du réseau.The lateral faces of the support 1 are at least partially metallized in the vicinity of the respective contacts between the connection terminals 8 and the ends 36 of the lines of the cable, to form a shielding sheath which is connected to a metallic sheath for shielding the cable (not shown in this figure). This shield is able to come into contact with a shield sheath surrounding the terminals of the female conductor, inside the housing 12. This shield of the female connector (not shown in the figures) is itself connected to a shield sheath network lines.
