Abstract
Description
La présente invention concerne un connecteur mâle déconnectable pour réseau de communication.The present invention relates to a male connector disconnectable for communication network.
Elle s'applique notamment aux réseaux de transmission utilisant des câbles multilignes tels que par exemple des réseaux, locaux ou non, qui permettent des transmissions de données informatiques ou des transmissions de données téléphoniques numériques. Il est indispensable de pouvoir raccorder en dérivation et/ou en série sur chacun de ces réseaux et de façon simple, un ou plusieurs équipements terminaux de traitement de données informatiques et/ou téléphoniques, selon le type de réseau considéré.It applies in particular to networks of transmission using multiline cables such as for example networks, local or not, which allow computer data transmissions or digital telephone data transmissions. he is essential to be able to connect in bypass and / or in series on each of these networks and so simple, one or more terminal equipment of processing of computer data and / or telephone, depending on the type of network considered.
Un connecteur mâle, qui permet de relier grâce aux 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 ses 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 allows to connect thanks to lines of a communication cable a terminal IT and / or telephone to a network, by insertion of this male connector into a connector female having its connection terminals connected to it network, is described, for example, in the request for European patent N ° 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 boltier 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 boltier du conducteur femelle. Cette fenêtre d'entrée présente des bords qui sont respectivement parallèles aux faces du support isolant du connecteur mâle. Le support isolant décrit dans cette demande de brevet comporte en outre une languette élastique rigide pour verrouiller la position du connecteur mâle.This patent application more precisely describes a universal connection set for connecting a processing terminal to a transmission network data. This universal set includes a connector male and female connector. The male connector includes an insulating support parallelepiped having two side faces, one side upper, lower face, front face and rear side, and connection terminals partially embedded in the support and leading to one of the upper or lower faces. These terminals are connected to lines of a communication cable surrounded by a insulating sheath and entering the support from its face back. Male connector connection terminals come into sliding contact with corresponding terminals of a female connector. These female connector terminals are located in a boltier and are respectively connected to lines of a communication network. Contacts between male connector and female connector terminals are established when the male connector is inserted in an entry window cutting out a front face of the female conductor bolt. This entry window has edges which are respectively parallel at the faces of the insulating support of the male connector. The insulating support described in this patent application further includes a rigid elastic tongue for lock the position of the male connector.
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.Male connectors of this type have the advantage essential to be very small and to ensure good locking of the position of the male connector in the female connector.
Mais de tels connecteurs mâles sont monoblocs ou peuvent être considérés comme monoblocs : c'est-à-dire que, lors d'une utilisation normale la partie connecteur mâle est indéformable. Pour réaliser la déconnexion entre le connecteur mâle et le connecteur femelle, une action humaine est indispensable. Le connecteur mâle reste donc connecté au connecteur femelle lors d'une traction sur le câble, avec toutes les conséquences très importantes qui peuvent en découler : risque pour une personne de trébucher à cause du câble et de tomber en se blessant, et entraíner dans son mouvement un appareil onéreux comme un ordinateur, ou un appareil de mesure.But such male connectors are one-piece or can be considered as monoblocks: i.e. that during normal use the part male connector is non-deformable. To achieve the disconnection between the male connector and the connector female, human action is essential. The male connector therefore remains connected to the connector female when pulling on the cable, with all the very important consequences that can ensue: risk for a person to trip over cause the cable to fall and injure yourself, and involve in its movement an expensive device like a computer, or a measuring device.
Une demande de brevet français n° 90 08831 déposée le 11 juillet 1990 décrit un connecteur mâle pour réseau de communication informatique et/ou téléphonique, de type décrit plus haut, qui comprend une targette s'engageant sous la languette élastique rigide et reliée au câble, pour libérer la languette, lors d'une traction sur le câble, lorsque le connecteur mâle est inséré dans le connecteur femelle. Ce connecteur permet donc 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, mais la structure de connecteur est assez compliquée à réaliser.A French patent application n ° 90 08831 filed July 11, 1990 describes a male connector for computer communication network and / or telephone, of the type described above, which includes a targette engaging under the elastic tongue rigid and connected to the cable, to release the tongue, when pulling on the cable, when the connector male is inserted into the female connector. This connector therefore allows in the event of untimely traction on the cable that connects the male connector to a device, when this connector is engaged in the female connector, to facilitate its disconnection, but the connector structure is quite complicated to achieve.
Les connecteurs mâles de l'art antérieur assurent le contact électrique entre un contact et un fil, correspondant à une ligne du câble de communication, par déplacement du contact et perforation de l'isolant du fil. Ils présentent, de ce fait, plusieurs inconvénients :
- la position du contact étant figée de façon précise par diverses normes (par exemple la norme ISO 8877), le sertissage nécessitant un outillage spécifique, et la position n'étant pas aisément vérifiable sur site de montage, des incertitudes subsistent sur la position et l'orientation des contacts vis-à-vis de ces normes.
- la tenue du contact pour tous les types de connecteurs est réalisée par harpon, cette méthode de fixation n'assure pas un positionnement correct des contacts. Leurs faces utiles, zone de liaison électrique, ont toutes des orientations différentes par rapport à la référence.
- un effort important est appliqué sur le contact pour perforer l'isolant, traverser les brins de cuivre, et assurer son maintien dans la matière plastique du connecteur. En conséquence, les différents points contacts avec les contacts et les fils correspondants d'un câble ne sont pas alignés sur une droite, mais plutôt sur une courbe. De plus, ces fils doivent être multibrins. L'effort mécanique détériore la surface du contact.
- the position of the contact being fixed in a precise manner by various standards (for example ISO 8877), the crimping requiring specific tools, and the position not being easily verifiable on the assembly site, uncertainties remain on the position and the 'orientation of contacts with regard to these standards.
- contact holding for all types of connectors is carried out by harpoon, this method of fixing does not ensure correct positioning of the contacts. Their useful faces, electrical connection area, all have different orientations compared to the reference.
- a significant effort is applied to the contact to perforate the insulation, pass through the copper strands, and ensure its retention in the plastic material of the connector. Consequently, the different contact points with the contacts and the corresponding wires of a cable are not aligned on a straight line, but rather on a curve. In addition, these wires must be multi-strand. Mechanical stress deteriorates the contact surface.
On connaít aussi par le document FR-A 2 379 918 un connecteur détachable de raccordement d'un câble de transmission de signaux à un dispositif d'interface d'équipement, en particulier d'engin largable. Ce connecteur est en deux parties qui sont verrouillées positivement ensemble. Sa partie mâle est ancrée de manière détachable sur le câble pour que le câble se sépare de cette partie, lors d'une traction importante sur lui.Document FR-A 2 379 918 also discloses a detachable connector for connecting a cable transmission of signals to an interface device of equipment, in particular of a dropable vehicle. This connector is in two parts which are positively locked together. Its male part is detachably anchored on the cable so that the cable separates from this part, during a significant pull on him.
Le document US-A-4 707 046 divulgue une solution analogue à la précédente, c'est-à-dire dans laquelle le câble se désolidarise de l'ensemble connecteur mâle - connecteur femelle.US-A-4,707,046 discloses a solution similar to the previous one, that is to say in which the cable separates from the male connector assembly - female connector.
Pour les applications visées par la présente demande ce mode de déconnexion n'est pas satisfaisant car il impose de refaire le raccordement du câble au connecteur mâle après toute déconnexion lors d'une traction intempestive sur le câble.For the applications covered by this request, this disconnection mode is not satisfactory because it requires reconnect the cable to the male connector after any disconnection during an untimely pull on the cable.
L'invention a pour objet de résoudre les problèmes de déconnexion lors d'une traction intempestive sur le câble en proposant une solution plus simple et moins coûteuse.The object of the invention is to solve the problems of disconnection during an untimely pull on the cable offering a simpler and less expensive solution.
L'invention a pour objet un connecteur mâle déconnectable pour réseau de communication, destiné à relier les fils de ligne d'un câble multiligne aux lignes du réseau par enfichage de ce connecteur mâle dans un connecteur femelle à bornes reliées aux lignes du réseau, comportant un boítier support dont une première partie terminale reçoit ledit câble et une deuxième partie terminale opposée forme une tête de connexion enfichable dans ledit connecteur femelle, des moyens de connexion montés dans ledit boítier support, reliés aux fils de ligne dudit câble et par ailleurs accessibles sur ladite tête de connexion, pour leur mise en contact avec lesdites bornes lors de l'enfichage de ladite tête dans le connecteur femelle, des moyens de blocage dudit câble dans ladite première partie terminale du boítier support, et des moyens de verrouillage prévus sur ladite tête de connexion pour son verrouillage dans ledit connecteur femelle, caractérisé en ce que ledit boítier support comporte ladite tête de connexion et un corps assemblés et séparables l'un de l'autre, tous deux pourvus à cet effet de moyens de solidarisation comportant des languettes latérales déformables sur ladite tête de connexion et des surfaces latérales d'appui sur ledit corps, solidarisant ladite tête de connexion en place sur ledit corps et les désolidarisant par traction intempestive sur ledit câble connecté audit réseau.The subject of the invention is a male connector disconnectable for communication network, intended to connect the line wires of a multiline cable to the network lines by plugging this male connector into a connector female terminal connected to the lines of the network, comprising a support housing of which a first terminal part receives said cable and an opposite second end portion forms a connection head pluggable into said connector female, connection means mounted in said housing support, connected to the line wires of said cable and by otherwise accessible on said connection head, for their brought into contact with said terminals when plugging in said head in the female connector, means for blocking of said cable in said first terminal part of the support housing, and locking means provided on said connection head for locking in said female connector, characterized in that said housing support comprises said connection head and a body assembled and separable from each other, both provided this effect of securing means comprising deformable side tabs on said head connection and lateral bearing surfaces on said body, securing said connection head in place on said body and dissociating them by untimely traction on said cable connected to said network.
Avantageusement, ladite tête de connexion est munie d'au moins une cavité et ledit corps d'un ergot qui entre dans ladite cavité pour le positionnement de ladite tête sur ledit corps. La tête de connexion comprend deux languettes latérales comportant chacune une face inclinée proche de son extrémité reçue dans le corps et ledit corps comprend deux parois latérales inclinées sur lesquelles prennent respectivement appui les faces inclinées des deux languettes pour constituer les moyens de solidarisation de la tête sur le corps.Advantageously, said connection head is provided with minus a cavity and said body of a lug which enters said cavity for positioning said head on said body. Connection head includes two tabs lateral each having an inclined face close to its end received in the body and said body comprises two inclined side walls on which take respectively support the inclined faces of the two tabs to constitute the means for securing the head on the body.
Un tel connecteur présente de nombreux avantages, et notamment :
- il permet de réduire le nombre de pièces utilisées en augmentant les fonctions de chacune,
- il permet une déconnexion rapide par une séparation en deux parties,
- il permet une diminution du coût de fabrication.
- it reduces the number of parts used by increasing the functions of each,
- it allows a quick disconnection by a separation into two parts,
- it allows a reduction in the manufacturing cost.
L'invention a également pour objet de résoudre les autres problèmes en séparant les fonctions : contact électrique avec les bornes du connecteur femelle, fixation sur le boítier support isolant, contact électrique avec les fils du câble, et en utilisant notamment une nouvelle façon de réaliser les contacts avec les fils du câble de communication.The object of the invention is also to resolve the other problems separating the functions: contact electrical with female connector terminals, fixing on the insulating support box, electrical contact with cable wires, and in particular using a new way to make the contacts with the wires of the cable communication.
Ainsi, dans une réalisation particulièrement avantageuse du connecteur de l'invention, les moyens de connexion comportent d'une part des premiers moyens de connexion auxdits fils du câble de communication, et d'autre part des seconds moyens de connexion par glissement avec les bornes du connecteur femelle, qui sont reliés les uns aux autres dans le corps.Thus, in a particularly advantageous embodiment of the connector of the invention, the connection means on the one hand have first connection means to said wires of the communication cable, and on the other hand second means of sliding connection with the terminals of the female connector, which are connected to each other in the body.
Avantageusement, des moyens de blocage du câble sont prévus dans l'extrémité du boítier opposée à ladite tête de connexion, afin que les fils ne puissent se déplacer.Advantageously, cable locking means are provided in the end of the housing opposite to said head connection, so that the wires cannot move.
Avantageusement, ce connecteur comprend un ensemble couvercle contenant lesdits moyens de blocage dudit câble et des moyens de raccordement recevant les fils du câble, adapté audit corps et bloqué sur celui-ci en le fermant et reliant les fils du câble aux premiers moyens de connexion.Advantageously, this connector comprises an assembly cover containing said means for blocking said cable and connection means receiving the wires of the cable, adapted to said body and blocked thereon by closing it and connecting the cable wires to the first connection means.
Les premiers moyens de connexion comportent des contacts en forme de fourche correspondant respectivement à chaque fil, chaque contact étant situé au-dessous de l'extrémité de l'un des fils de manière telle que lors de l'enfoncement de l'ensemble couvercle sur le corps, chaque extrémité de fil soit sertie dans la fourche de l'un de ces contacts. Chaque contact comprend au moins deux branches munies chacune, sur sa ou ses faces internes, d'au moins une aspérité destinée à déchirer la gaine du fil correspondant et ainsi réaliser le contact avec l'âme de celui-ci. Ces contacts en forme de fourche sont rapportés à la surface d'un circuit imprimé comportant des pistes imprimées constituant les seconds moyens de connexion avec les bornes respectives du connecteur femelle.The first connection means include contacts fork-shaped corresponding respectively to each wire, each contact being located below the end of one of the wires in such a way that when the the cover assembly on the body, each end of the wire either crimped into the fork of one of these contacts. Each contact comprises at least two branches each provided, on its internal face or faces, of at least one roughness intended for tear the sheath of the corresponding wire and thus carry out the contact with the soul of it. These shaped contacts fork are brought to the surface of a printed circuit comprising printed tracks constituting the second means of connection with the respective terminals of the female connector.
Avantageusement, ladite tête de connexion comporte une cavité principale recevant ledit circuit imprimé et présente des parois inclinées sur lesquelles repose le circuit imprimé et des gorges de guidage pour recevoir les bornes du connecteur femelle et les positionner sur les pistes du circuit imprimé.Advantageously, said connection head comprises a main cavity receiving said printed circuit and presents inclined walls on which the circuit rests printed and guide grooves to receive the terminals of the female connector and position them on the tracks of the printed circuit board.
Avantageusement, les moyens de raccordement sont munis de plusieurs logements dans lesquels sont introduites les extrémités des fils du câble de communication. L'ensemble couvercle comporte une partie arrière, par laquelle peut être introduite et bloquée l'extrémité du câble dont la gaine a été enlevée pour libérer l'extrémité des fils, et une partie avant dans laquelle sont montés lesdits moyens de raccordement recevant les extrémités des fils guidés par une portée inclinée entre lesdites parties arrière et avant. Dans sa partie arrière, ce couvercle est muni de deux parois latérales munies de crémaillères internes entre lesquelles peut être introduite une pièce de blocage appartenant aux moyens de blocage du câble et munie de crémaillères externes prévues pour s'adapter aux crémaillères internes du couvercle. Cette pièce de blocage comprend également, sur chacune de ses faces latérales, un ergot prévu pour se déplacer dans une rainure réalisée dans la partie médiane de chaque crémaillère interne du couvercle.Advantageously, the connection means are provided of several dwellings into which the ends of the communication cable wires. All cover has a rear part, through which can be inserted and blocked at the end of the cable, the sheath has been removed to free the end of the wires, and a front part in which are mounted said means of connection receiving the ends of the wires guided by a inclined range between said rear and front parts. In its rear part, this cover is provided with two walls side fitted with internal racks between which a blocking piece belonging to the cable locking means and provided with external racks designed to adapt to the internal racks of the lid. This locking piece also includes, on each of its side faces, a lug provided for move in a groove made in the middle part of each internal rack of the cover.
Le couvercle comporte des fentes latérales lui permettant de s'adapter aux parois latérales dudit corps, et des rainures verticales prévues pour venir s'adapter respectivement sur des saillies verticales situées sur les parois latérales dudit corps.The cover has side slits making it possible to adapt to the side walls of said body, and vertical grooves provided to adapt respectively on vertical projections located on the side walls of said body.
Une répartition avantageuse des pièces du connecteur de l'invention se basant sur deux fonctions, comporte :
- d'une part, les éléments servant au blocage mécanique qui sont les moyens de blocage de câble, le couvercle venant s'emboíter dans le support pour fermer l'ensemble : ces pièces peuvent être en matière plastique métallisée afin qu'il y ait continuité avec le blindage du câble et le nième point, par exemple le neuvième point, du connecteur femelle.
- d'autre part, les éléments servant au positionnement, qui sont les moyens de raccordement localisant les fils du câble dans les logements, la tête de connexion positionnant les bornes du connecteur femelle face à chaque piste du circuit imprimé. Ces pièces peuvent être en matière plastique isolante transparente afin de visualiser les divers éléments de connexion, comme la position des fils dans les moyens de raccordement, ou encore le positionnement du circuit imprimé dans la tête de connexion, cette dernière ne pouvant être conductrice sous peine de relier les pistes entre elles, auquel cas on aurait un point électrique commun contrairement à ce qui est recherché et qui est d'obtenir la transmission de par exemple huit lignes indépendantes.
- on the one hand, the elements serving for the mechanical blocking which are the cable blocking means, the cover fitting into the support to close the assembly: these parts can be made of metallized plastic so that there is continuity with the cable shield and the nth point, for example the ninth point, of the female connector.
- on the other hand, the elements used for positioning, which are the connection means locating the wires of the cable in the housings, the connection head positioning the terminals of the female connector facing each track of the printed circuit. These parts can be made of transparent insulating plastic material in order to visualize the various connection elements, such as the position of the wires in the connection means, or even the positioning of the printed circuit in the connection head, the latter being unable to be conductive under pain. to connect the tracks together, in which case there would be a common electrical point, contrary to what is sought and which is to obtain the transmission of, for example, eight independent lines.
Un connecteur ayant de telles caractéristiques présente de nombreux avantages, et notamment :
- La position de chaque point de contact est fixée avant le sertissage des fils par un moyen ne nécessitant que des efforts très modérés.
- La tenue des contacts est réalisée par un moyen sans déformation mécanique de matière, par exemple collage surmoulage ou soudés sur un circuit imprimé.
- Pour assurer la mise en place des contacts, il n'est plus nécessaire d'exercer un effort important, les points contact sont donc bien positionnés et alignés.
- En reportant vers l'arrière le sertissage des fils, on peut utiliser des fils ayant un diamètre sur isolant plus important, ce qui permet d'utiliser des câbles ayant des caractéristiques plus performantes.
- The position of each contact point is fixed before the crimping of the wires by a means requiring only very moderate forces.
- The holding of the contacts is carried out by a means without mechanical deformation of material, for example bonding overmolding or soldered on a printed circuit.
- To ensure the establishment of the contacts, it is no longer necessary to exert a significant effort, the contact points are therefore well positioned and aligned.
- By deferring back the crimping of the wires, it is possible to use wires having a larger diameter on insulator, which makes it possible to use cables having more efficient characteristics.
Dans une variante de réalisation, chaque contact en forme de fourche est la première extrémité d'une borne de connexion partiellement noyée dans le support, et dont la seconde extrémité permet de réaliser le contact avec les bornes respectives du connecteur femelle.In an alternative embodiment, each contact fork-shaped is the first end of a connection terminal partially embedded in the support, and the second end of which allows the contact with the respective connector terminals female.

La figure 1 représente schématiquement un réseau
de transmission de données entre deux stations 2, 3
communiquant au moyen d'un câble multilignes.
L'ensemble de connexion 4 permet de brancher, en
dérivation sur ce réseau, par un câble de connexion 5,
un autre terminal ou une autre station 6. Cet ensemble
de connexion comporte un connecteur femelle relié à
deux tronçons successifs 7, 8 du câble de
communications du réseau, et le connecteur mâle de
l'invention relié au câble de connexion 5. Le câble de
connexion 5, comme les tronçons de câbles 7, 8 de
transmission du réseau, est de préférence un câble
multilignes avec blindage de masse. Il peut, par
exemple, contenir huit lignes conductrices constituée
chacune d'un conducteur entouré d'une gaine isolante.
Il peut également comporter un blindage de masse,
constitué par exemple par une enveloppe métallique
enroulée autour des lignes.Figure 1 schematically represents a network
data transmission between two
Dans ce type de câble multilignes, certaines lignes sont destinées à assurer des transmissions dans un premier sens, tandis que d'autres lignes sont destinées à assurer des transmissions dans un sens opposé.In this type of multi-line cable, some lines are intended to ensure transmissions in a first sense, while other lines are intended to ensure one-way transmissions opposite.
Un connecteur mâle pour réseau de communication
informatique et/ou téléphonique de l'art antérieur est
représenté schématiquement et en coupe longitudinale
sur la figure 2. Ce connecteur comporte un support
isolant parallélépipédique 20. Des bornes de connexion
21 sont partiellement noyées dans le support 20 et
débouchent sur la face supérieure du support. Ces
bornes sont reliées à des fils 22 formant les lignes
d'un câble de communication 23 entourées d'une gaine
isolante et entrant dans le support 20 par sa face
arrière 24.A male connector for communication network
computer and / or telephone of the prior art is
shown schematically and in longitudinal section
in Figure 2. This connector has a support
Les bornes de connexion 21 du connecteur mâle
entrent respectivement en contact par glissement avec
des bornes correspondantes 25 d'un connecteur femelle.
Les bornes du connecteur femelle sont enfermées dans un
boítier 26 et sont respectivement reliées à des lignes
du réseau de communication. Le boltier du connecteur
femelle présente une fenêtre d'entrée qui permet
l'insertion du connecteur mâle.The
Le support 20 représenté sur la figure 2 comporte
aussi une languette élastique rigide 27, rendue
solidaire de ce support, au voisinage de ses faces
inférieure et avant par une embase 28 plus large que la
languette 27. Cette languette 27 et cette embase 28
sont inclinées par rapport à la face inférieure du
rapport 20 et s'engagent dans une découpe
correspondante de la face avant du boltier 26. L'embase
28 comporte un épaulement transversal de verrouillage
29. Pour faciliter l'insertion du connecteur mâle dans
le connecteur femelle, l'embase 28 et l'épaulement 29
peuvent être reliés par une surface inclinée.
L'épaulement 29 est lui aussi de préférence incliné,
comme représenté sur la figure.The
Au cours de l'insertion du connecteur mâle dans la
fenêtre du connecteur femelle, la languette 27 et
l'embase 28 se rabattent progressivement vers la face
inférieure du support 20 par appui et glissement de
cette embase et de la surface inclinée sur les bords de
la découpe 30. A la fin de l'insertion, la languette 27
et l'embase 28 s'éloignent de la face inférieure du
support 20 pour verrouiller la position du connecteur
mâle par appui de l'épaulement 29 sur une paroi interne
de la face avant du boítier 26.During the insertion of the male connector into the
female connector window,
Le connecteur comporte, de plus, un cavalier 35 en
matière isolante par exemple, qui vient enserrer le
support 20, au voisinage de la face arrière 24 de ce
support. Ce cavalier recouvre partiellement les faces
latérales et la face supérieure du support, pour
appuyer sur l'extrémité 36 de chaque fil 22, du câble
de communication 23 présent à l'intérieur du support
20 ; cet appui permet d'assurer les contacts respectifs
entre les extrémités des fils et les bornes
correspondantes du connecteur mâle. Chaque borne de
connexion 21 présente, du côté de la face arrière 24 du
support 20, une forme en pointe permettant grâce à
l'appui du cavalier 35 sur la ligne 22, de perforer
l'isolant entourant ce fil jusqu'au conducteur entouré
par cet isolant ; la borne et le conducteur du fil sont
alors en contact. Le cavalier 35 est maintenu sur le
support 20 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 20. Le cavalier 35 assure un
blocage efficace des fils 22 du câble 23.The connector further comprises a
Les faces latérales du support 20 sont au moins
partiellement métallisées au voisinage des contacts
respectifs entre les bornes de connexion 21 et les
extrémités 36 des fils du câble, pour former un
fourreau de blindage qui est relié à une gaine
métallique de blindage du câble. Ce blindage est apte à
entrer en contact avec un fourreau de blindage
entourant les bornes du conducteur femelle, à
l'intérieur du boítier 26. Le blindage du connecteur
femelle est lui-même relié à un fourreau de blindage
des lignes du réseau.The lateral faces of the
Mais un tel connecteur présente de nombreux défauts :
- il n'y a pas de déconnexion en cas de traction intempestive sur le câble,
- il existe des incertitudes sur la position et l'orientation des points contacts entre les fils et les bornes vis-à-vis des normes,
- la méthode de fixation des contacts utilisée n'assure par un bon positionnement de ceux-ci,
- les points de contacts ne sont pas alignés.
- there is no disconnection in the event of untimely pulling on the cable,
- there are uncertainties about the position and orientation of the contact points between the wires and the terminals with regard to standards,
- the method of fixing the contacts used does not ensure a good positioning of these,
- the contact points are not aligned.
Pour pallier ces différents défauts, le connecteur de l'invention permet de séparer d'une part les fonctions : connexion et verrouillage et d'autre part les fonctions contact électrique avec les bornes du connecteur femelle, fixation sur le support en matière isolante, contact électrique avec les fils du câble.To overcome these various faults, the connector of the invention makes it possible on the one hand to separate the functions: connection and locking and secondly the electrical contact functions with the terminals of the female connector, fixing on the material support insulating, electrical contact with cable wires.
Ainsi, comme représenté sur les figures 3 et 4, le connecteur mâle de l'invention comprend deux parties :
un boltier support 40 comprenant deux parties 80 en matériau isolant et 81 en matériau métallisé pouvant être séparées, la première partie 80 étant munie dans sa partie inférieure d'une languette élastique rigide 41,un ensemble couvercle 100 comprenant une pièce de raccordement 91 en matière isolante positionnant les fils 43 de la pièce 54 en matière métallisée bloquant le câble 44 de communication et d'un couvercle 42 en matière métallisée.
- a
support bolt 40 comprising twoparts 80 of insulating material and 81 of metallized material which can be separated, thefirst part 80 being provided in its lower part with a rigidelastic tongue 41, - a
cover assembly 100 comprising a connectingpiece 91 of insulating material positioning thewires 43 of thepiece 54 of metallized material blocking thecommunication cable 44 and of acover 42 of metallized material.
Le boltier support 40 comprend dans sa partie
avant 80 une cavité 45 dans laquelle peut être disposé
un circuit imprimé 46 qui repose alors dans sa partie
avant sur des parois inclinées 47 de la partie avant
80, et dans ses parties arrière et centrale sur des
ergots 48 et 48' de la partie arrière 81. Dans sa
partie arrière, le circuit imprimé 46 est inséré dans
la gorge 78 d'une butée 79 solidaire du corps 81. Sur
la partie avant 80, la cavité 45 débouche vers
l'extérieur par des gorges de guidage 49 permettant de
bien guider les contacts du connecteur femelle vers les
contacts du circuit imprimé 46 correspondant.The
Le boítier 40 est donc constitué de deux parties :
une pièce 80 ou tête de connexion et une pièce 81 ou
corps, qui peut être métallisé entièrement assurant
ainsi la protection des données transmises contre les
émissions d'ondes électromagnétique ou de l'électricité
statique.The
La tète de connexion 80 possède une cavité 82
permettant de recevoir un ergot 83 du corps 81. Cet
ergot permet de positionner les deux pièces entre
elles. Le circuit imprimé 46 assure entre les deux
pièces 80 et 81 un guidage transversal.The
Le maintien de la pièce 80 sur la pièce 81 est
réalisé par les languettes 84 et 85. Ces languettes
prennent appui sur des faces inclinées 86 et 87 de la
pièce 81 par l'intermédiaire des faces 88 et 89 de
manière à permettre ce maintien.Maintaining the
En fonctionnement normal, le connecteur ne peut
reculer, il est bloqué en position retrait par une
butée sur le connecteur femelle qui prend appui sur une
face 51 de la languette 41. Une traction sur le câble
du connecteur rend solidaires le connecteur mâle et le
connecteur femelle. In normal operation, the connector cannot
back off, it is blocked in the retracted position by a
stop on the female connector which is supported on a
Comme dans le connecteur de l'art antérieur, la
languette 41 est rendue solidaire du support par une
embase plane 50, plus large que la languette. Cette
languette 41 et cette embase 50 sont inclinées.
L'embase 50 qui relie la languette 41 au support 40
comporte un épaulement transversal 51 permettant, en
fin d'insertion, le verrouillage du connecteur mâle
dans le connecteur femelle qui n'a pas été représenté
sur la figure 3, mais qui apparaít schématiquement sur
la figure 2.As in the connector of the prior art, the
Le couvercle 42 comporte une partie arrière par
laquelle peut être introduite l'extrémité du câble 44
dont la gaine a été enlevée pour libérer l'extrémité
des fils 43.The
Dans sa partie avant, le couvercle 42 rejoint la
pièce 91 munie de logements 70 pour les extrémités de
fils reliés à la partie arrière par une portée inclinée
52.In its front part, the
Dans sa partie arrière, le couvercle 42 comprend
deux parois latérales munies de crémaillères internes
53 entre lesquelles peut être introduite une pièce de
blocage 54 du câble, munie de crémaillères externes 55
prévues pour s'adapter aux crémaillères internes 53 du
couvercle 42. Cette pièce de blocage 54 comprend
également, sur chacune de ses faces latérales, un ergot
56 prévu pour se déplacer dans une rainure 57 réalisée
dans chaque crémaillère du couvercle 42. Le couvercle
42 comporte des fentes latérales 60 lui permettant de
s'adapter aux parois du support 40. Il comprend
également des rainures verticales 61 prévues pour venir
s'adapter respectivement sur des saillies verticales 62
situées sur les faces latérales dudit support 40.In its rear part, the
Le connecteur mâle forme donc un ensemble
déformable qui peut se scinder en deux : la pièce 80
qui comprend la languette 41 et le corps 81. Le
connecteur mâle étant en position assemblée représentée
sur la figure 4, les faces 88 et 89 de la tête de
connexion 80 sont en contact avec les faces 86 et 87 du
corps 81. Une traction sur le câble plaque le
connecteur mâle sur le connecteur femelle par
l'intermédiaire de la surface 51, un effort de traction
tend à écarter les pièces 80 et 81. Les faces d'appui
(86, 87, 88, 89) entre ces deux pièces sont inclinées à
l'effort. Ce dernier peut se décomposer en une
composante parallèle à l'effort de traction et une
composante perpendiculaire à l'effort de traction. La
composante perpendiculaire a tendance à rapprocher les
deux languettes 84 et 85 l'une de l'autre et donc de
permettre à la pièce 80 de se désolidariser de la pièce
81, et donc de l'ensemble du connecteur mâle.The male connector therefore forms a set
deformable which can be split in two:
Dans la suite de la description, pour simplifier
l'explication, on parlera de support 40 pour désigner
l'ensemble des deux parties 80 et 81 solidarisées entre
elles.In the following description, to simplify
the explanation, we will speak of
Le circuit imprimé 46, tel que représenté sur la
figure 5 comporte des pistes conductrices 64 à
l'extrémité desquelles des contacts 65 en forme de
fourches, par exemple à trois branches 66 peuvent être
introduits dans des trous métallisés 67. Ces contacts
sont disposés en quinconce selon deux lignes
transversales. Une fois le circuit imprimé 46 disposé
dans le support 40, chaque contact est situé au-dessous
de l'extrémité d'un fil 43 de manière telle que lors de
l'enfoncement de l'ensemble couvercle 100 sur le
support 40, chaque extrémité de fil 43 soit sertie
entre les branches 66 d'un contact 65.The printed
Chaque contact 65 comprend au moins deux branches
66 munies chacune sur sa (ou ses) face(s) interne(s)
d'au moins une aspérité 68 destinée à déchirer la gaine
du fil 43 et ainsi réaliser un contact avec l'âme du
fil.Each
Ces contacts sont donc rapportés à la surface du
circuit imprimé 46 qui comporte des pistes imprimées 64
permettant de réaliser le contact avec les bornes
respectives du connecteur femelle. Ces contacts sont
réalisés en un matériau conducteur dur, par exemple du
bronze-béryllium.These contacts are therefore related to the surface of the
printed
Avantageusement, le câble 44 peut comprendre un
écran et un drain, fil non isolé qui longe l'écran ; le
couvercle 42, la pièce 81 du support 40 et la pièce de
blocage 54 peuvent alors être métallisés et reliés
électriquement par contact à cet écran et à ce drain
afin de protéger la transmission de données des
émissions d'ondes électromagnétiques ou de
l'électricité statique.Advantageously, the
Sur les figures 3 et 4, le support 40 et
l'ensemble couvercle 100 sont représentés en deux
positions distinctes et consécutives : en une première
position dans laquelle ils sont séparés, en une
seconde position dans laquelle ils sont rendus
solidaires l'un de l'autre.In FIGS. 3 and 4, the
On peut proposer une autre répartition des pièces de l'ensemble, en se basant sur deux fonctions :
- d'une part, les éléments servant au blocage
mécanique qui sont le blocage de câble 54, le couvercle
42 venant s'emboíter dans le
support 81 pour fermer l'ensemble. Ces pièces peuvent être en matière plastique métallisée afin qu'il y ait continuité avec le blindage du câble et le nième point, par exemple le neuvième, du connecteur femelle. - d'autre part, les éléments servant au
positionnement des pièces extérieures : la pièce de
raccordement 91 localise les fils 43 du câble 44 dans
les logements 70,
la pièce 80 positionne les contacts du connecteur femelle face à chaque piste du circuit imprimé. Ces pièces peuvent être en matière plastique isolante transparente afin de visualiser les divers éléments de connexion, comme la position des fils dans la pièce 91, ou encore le positionnement du circuit imprimé dans la pièce 80, cette dernière ne pouvant être conductrice sous peine de relier les pistes entre elles, auquel cas on aurait un point électrique commun contrairement à ce qui est recherché et qui est d'obtenir la transmission de par exemple huit lignes indépendantes.
- on the one hand, the elements serving for the mechanical blocking which are the cable blocking 54, the
cover 42 fitting into thesupport 81 to close the assembly. These parts can be made of metallized plastic so that there is continuity with the cable shield and the nth point, for example the ninth, of the female connector. - on the other hand, the elements used for positioning the external parts: the connecting
part 91 locates thewires 43 of thecable 44 in thehousings 70, thepart 80 positions the contacts of the female connector facing each track of the printed circuit. These parts may be made of transparent insulating plastic material in order to visualize the various connection elements, such as the position of the wires in thepart 91, or even the positioning of the printed circuit in thepart 80, the latter being unable to be conductive under penalty of connecting the tracks between them, in which case there would be a common electrical point, contrary to what is sought and which is to obtain the transmission of, for example, eight independent lines.
On va analyser à présent les différentes étapes de
mise en place des éléments du connecteur mâle de
l'invention.
Lorsque le connecteur mâle ainsi formé est
introduit dans un connecteur femelle correspondant, on
réalise une continuité électrique pour chaque fil du
câble avec le contact en vis-à-vis du connecteur
femelle en passant par le circuit imprimé 46, tout en
assurant un blindage électromagnétique au niveau de la
connexion.When the male connector thus formed is
inserted into a corresponding female connector, we
provides electrical continuity for each wire in the
cable with contact opposite connector
female via the printed
Un tel connecteur présente de nombreux avantages, et notamment :
- le connecteur mâle ainsi réalisé se scinde en
deux parties (
partie 80 d'un côté, partie 81,circuit imprimé 46et ensemble couvercle 100 de l'autre) lors d'une traction intempestive sur le câble 44. - la face supérieure du circuit imprimé qui comporte des pistes assurant le contact avec le connecteur femelle, permet un positionnement franc et précis de la surface de contact vis-à-vis d'une référence de connexion définie dans la norme.
- la fixation des contacts dans le support est réalisée par une méthode sans contrainte par exemple collage, remplissage de résine, soudage ; de ce fait, aucune contrainte n'est exercée sur le connecteur et la déformation vue de bout est nulle.
- la jonction électrique de ce contact avec les fils du câble est réalisée sur la partie arrière de ce contact par déplacement des fils sur les contacts, l'effort de connexion n'est plus additionné à l'effort de fixation des contacts.
- la liaison avec les fils du câble étant reportée à plusieurs millimètres en arrière de la face avant du connecteur, il est possible d'utiliser des fils avec des diamètres sur isolant différents. En effet, la norme fixe la largeur du connecteur, mais à un certain niveau cette largeur est libre. On peut donc écarter les zones de connexion des fils. On peut donc utiliser des fils avec des jauges de numéro plus faible. De plus, ces fils peuvent être monobrin ou multibrins.
- the male connector thus produced splits into two parts (
part 80 on one side,part 81, printedcircuit 46 andcover assembly 100 on the other) during an untimely pulling on thecable 44. - the upper face of the printed circuit which has tracks ensuring contact with the female connector, allows a frank and precise positioning of the contact surface with respect to a connection reference defined in the standard.
- the fixing of the contacts in the support is carried out by a method without constraint for example gluing, filling of resin, welding; therefore, no stress is exerted on the connector and the deformation seen from the end is zero.
- the electrical junction of this contact with the wires of the cable is produced on the rear part of this contact by displacement of the wires on the contacts, the connection effort is no longer added to the effort for fixing the contacts.
- the connection with the wires of the cable being postponed several millimeters behind the front face of the connector, it is possible to use wires with diameters on different insulation. Indeed, the standard fixes the width of the connector, but at a certain level this width is free. We can therefore discard the connection areas of the wires. We can therefore use wires with lower number gauges. In addition, these wires can be single-strand or multi-strand.
Dans une variante de réalisation, le contact peut être réalisé par une borne de connexion, de même type que celle représentée sur la figure 2 ; cette borne ayant alors son extrémité arrière en forme de fourche à plusieurs branches, pour que le fil correspondant puisse être serti de la manière représentée notamment à la figure 5.In an alternative embodiment, the contact can be made by a connection terminal, of the same type than that shown in Figure 2; this terminal then having its rear end in the form of a fork several branches, so that the corresponding wire can be crimped in the manner shown in particular at Figure 5.
