Description

La présente invention se rapporte à un connecteur basse tension destiné à être employé dans un système de communication. L'invention concerne plus précisément un connecteur de type RJ, plus particulièrement de type RJ45. L'invention concerne également le procédé de montage du connecteur de l'invention sur un câble.The present invention relates to a low voltage connector for use in a communication system. The invention relates more precisely to an RJ-type connector, more particularly of the RJ45 type. The invention also relates to the method of mounting the connector of the invention on a cable.

Un connecteur de type RJ se présente souvent en deux parties. La première partie comporte des contacts autodénudants. La deuxième partie comporte un support organisateur de fils disposant de plusieurs emplacements destinés chacun à accueillir un fil du câble. Lorsque la première partie est assemblée sur la deuxième partie, chaque fil du câble positionné à un emplacement du support vient se dénuder dans un contact autodénudant de la première partie de manière à établir un contact électrique pour chaque fil du câble.An RJ-type connector is often in two parts. The first part has insulation displacement contacts. The second part comprises a wire organizer support having several locations each for receiving a cable wire. When the first part is assembled on the second part, each wire of the cable positioned at a location of the support is stripped in an insulation displacement contact of the first part so as to establish an electrical contact for each wire of the cable.

Les demandes de brevets EP2061118 , WO0150548 et US6371794 décrivent de tels connecteurs en deux parties.Patent applications EP2061118 , WO0150548 and US6371794 describe such connectors in two parts.

Lors du montage du connecteur sur le câble et notamment lors de la fermeture du connecteur, un effort trop important sur le câble peut entraîner un désengagement des fils de leur emplacement sur le support. Le montage du connecteur doit alors être effectué de nouveau. Les documents cités ci-dessus ne décrivent pas de solutions permettant de surmonter cet inconvénient. Le document précité US6371794 cité ci-dessus décrit un mécanisme de bride mais ce mécanisme est situé sur la première partie qui comporte les contacts autodénudants ce qui ne permet pas d'éviter le désengagement des fils au niveau de l'organisateur de fils.When mounting the connector on the cable and in particular when closing the connector, too much stress on the cable may cause the wires to disengage from their location on the support. The connector mounting must then be performed again. The documents cited above do not describe solutions to overcome this disadvantage. The aforementioned document US6371794 cited above describes a flange mechanism but this mechanism is located on the first part which has the insulation displacement contacts which does not prevent the disengagement of the son at the level of the son organizer.

Le but de l'invention est de proposer un connecteur dont le montage est aisé et permet à coup sûr d'éviter le désengagement des fils du support organisateur.The object of the invention is to provide a connector whose mounting is easy and certainly avoids the disengagement of the son of the organizer support.

Ce but est atteint par un connecteur basse tension pour système de communication, ledit connecteur étant destiné à recevoir un câble doté de plusieurs fils, et comportant :

  • une première partie apte à se connecter par sa face avant sur un connecteur complémentaire et comprenant des contacts autodénudants sur chacun desquels peut se connecter l'un des fils contenus dans le câble,
  • une deuxième partie comportant une ouverture formant un chemin de passage du câble et supportant un support organisateur de fils du câble qui comporte plusieurs emplacements destinés à recevoir chacun une extrémité d'un fil du câble en vue de son insertion dans un contact autodénudant de la première partie,
  • un mécanisme de charnière pour articuler la deuxième partie par rapport à la première partie autour d'un premier axe de rotation en vue d'ouvrir ou de fermer le connecteur,
  • le connecteur comportant un organe de verrouillage assemblé sur la deuxième partie du connecteur et destiné à verrouiller le câble dans l'ouverture de la deuxième partie du connecteur, et
  • l'organe de verrouillage comprenant un organe de fermeture apte à coopérer avec un organe de fermeture complémentaire réalisé sur la première partie pour fixer la première partie sur la deuxième partie.
This object is achieved by a low-voltage connector for communication system, said connector being intended to receive a cable with several wires, and comprising:
  • a first part adapted to be connected by its front face to a complementary connector and comprising insulation displacement contacts on each of which can connect one of the son contained in the cable,
  • a second portion having an opening forming a pathway of the cable and supporting a cable conductor support of the cable which has a plurality of locations for each receiving an end of a wire of the cable for insertion into an insulation displacement contact of the first part,
  • a hinge mechanism for articulating the second portion with respect to the first portion about a first axis of rotation to open or close the connector,
  • the connector comprising a locking member assembled on the second part of the connector and for locking the cable in the opening of the second part of the connector, and
  • the locking member comprising a closure member adapted to cooperate with a complementary closure member formed on the first part to fix the first part on the second part.

Selon une particularité, l'organe de verrouillage est pivotant entre une position d'ouverture et une position de fermeture et articulé sur une partie fixe autour d'un second axe de rotation perpendiculaire au premier axe de rotation.According to one feature, the locking member is pivotable between an open position and a closed position and articulated on a fixed portion about a second axis of rotation perpendicular to the first axis of rotation.

Selon une autre particularité, la deuxième partie comporte des moyens de maintien de l'organe de verrouillage en position de fermeture sur la partie fixe, lesdits moyens de maintien comportant un crochet apte à coopérer avec un élément de fermeture complémentaire.According to another feature, the second part comprises means for holding the locking member in the closed position on the fixed part, said holding means comprising a hook adapted to cooperate with a complementary closure element.

Selon une autre particularité, le second axe de rotation est parallèle au chemin de passage du câble à travers l'ouverture.According to another feature, the second axis of rotation is parallel to the path of passage of the cable through the opening.

Selon une autre particularité, l'organe de verrouillage comporte une pièce de serrage mobile en translation de manière transversale par rapport au chemin de passage du câble et assemblé sur un ressort.According to another feature, the locking member comprises a clamping piece movable in translation transversely with respect to the passage path of the cable and assembled on a spring.

Selon une autre particularité, l'ouverture a la forme d'une fente destinée à accueillir le câble dans un mouvement de translation parallèle à son axe, et dont l'embouchure est ouverte ou fermée selon la position de l'organe de verrouillage.According to another feature, the opening has the shape of a slot for receiving the cable in a translation movement parallel to its axis, and whose mouth is open or closed according to the position of the locking member.

Selon une particularité du connecteur dans sa version STP, la deuxième partie comporte une pièce métallique agencée sur le support organisateur de fils pour recevoir le drain du câble et en contact électrique avec le corps en matériau métallique de la deuxième partie.According to a feature of the connector in its STP version, the second part comprises a metal part arranged on the wire-organizing support for receiving the drain of the cable and in electrical contact with the metal material body of the second part.

Selon une autre particularité, l'organe de fermeture comporte une fente apte à coopérer avec un crochet réalisé sur la première partie.According to another feature, the closure member comprises a slot adapted to cooperate with a hook made on the first part.

Selon une autre particularité, le crochet est actionnable en pivotement à l'aide d'un bouton.According to another feature, the hook is operable in pivoting with the help of a button.

L'invention concerne également le procédé de montage du connecteur décrit ci-dessus sur un câble doté de plusieurs fils. Ce procédé de montage comporte :

  • une étape de passage du câble à travers l'ouverture réalisée à travers la deuxième partie du connecteur,
  • une étape de verrouillage du câble sur la deuxième partie du connecteur,
  • une étape d'organisation des fils du câble sur le support organisateur de fils,
  • une étape de fermeture du connecteur en pivotant la deuxième partie sur la première partie de manière à insérer les fils du câble dans les contacts autodénudants.
The invention also relates to the method of mounting the connector described above on a cable with several son. This mounting method comprises:
  • a step of passage of the cable through the opening made through the second part of the connector,
  • a locking step of the cable on the second part of the connector,
  • a step of organizing the wires of the cable on the wire organizer,
  • a step of closing the connector by pivoting the second part on the first part so as to insert the son of the cable into the insulation displacement contacts.

Dans la suite de la description, on définit un axe principal (A) par la direction d'introduction du connecteur de l'invention dans un connecteur correspondant, cet axe passant par l'avant et l'arrière du connecteur.In the remainder of the description, a main axis (A) is defined by the insertion direction of the connector of the invention in a corresponding connector, this axis passing through the front and the rear of the connector.

Le connecteur basse tension selon l'invention est de type Jack, plus précisément de type RJ (pour "Registered Jack"), pour pouvoir être utilisé dans un système de communication fonctionnant par exemple sous le protocole Ethernet. Le connecteur selon l'invention est de type femelle.The low-voltage connector according to the invention is of the Jack type, more precisely of RJ type (for "Registered Jack"), to be used in a communication system operating for example under the Ethernet protocol. The connector according to the invention is of the female type.

Le connecteur femelle selon l'invention présente deux configurations distinctes selon que le câble auquel il est raccordé est blindé (STP pour "Shielded Twisted Pair" ou FTP pour "Foiled Twisted Pair") ou non-blindé (UTP pour "Unshielded Twisted Pair"). La description ci-dessous s'adresse aux deux versions du connecteur, la version STP étant représentée sur les figures 1 à 6 et la version UTP sur les figures 7 à 9. Dans la version STP, le corps du connecteur est en matériau métallique tandis que dans la version UTP, le corps du connecteur est en matériau plastique.The female connector according to the invention has two distinct configurations depending on whether the cable to which it is connected is shielded (STP for "Shielded Twisted Pair" or FTP for "Foiled Twisted Pair") or unshielded (UTP for "Unshielded Twisted Pair" ). The description below is for both versions of the connector, the STP version being represented on the Figures 1 to 6 and the UTP version on Figures 7 to 9 . In the STP version, the connector body is made of metallic material while in the UTP version, the connector body is made of plastic material.

Des références communes sont utilisées pour les deux versions du connecteur dans la mesure où les éléments référencés présentent une fonction identique dans les deux versions.Common references are used for both versions of the connector because the referenced elements have the same function in both versions.

Dans les deux configurations, le connecteur comporte un corps constitué de deux parties 1, 2, une première partie 1 et une deuxième partie 2 reliées entre elles par une liaison en pivot réalisée autour d'un premier axe de rotation (R1) perpendiculaire à l'axe principal (A). Le connecteur est ainsi susceptible d'être en position ouverte lors de l'assemblage sur le câble ou en position fermée lorsque son assemblage sur le câble est terminé.In both configurations, the connector comprises a body consisting of two parts 1, 2, a first portion 1 and a second portion 2 interconnected by a pivot connection formed around a first axis of rotation (R1) perpendicular to the main axis (A). The connector is thus likely to be in the open position during assembly on the cable or in the closed position when its assembly on the cable is completed.

La première partie 1 présente une face avant 10 formant un logement ou empreinte (non visible) destiné à recevoir un connecteur mâle complémentaire (non représenté). Des lamelles souples, au nombre de huit dans un connecteur RJ45, sont prévues dans le logement. Ces lamelles souples sont aptes à se déformer élastiquement lors de l'enfichage du connecteur mâle complémentaire pour établir un contact électrique avec des pistes formées sur le connecteur mâle complémentaire.The first part 1 has a front face 10 forming a housing or imprint (not visible) for receiving a complementary male connector (not shown). Flexible slats, eight in number in an RJ45 connector, are provided in the housing. These flexible strips are able to deform elastically when plugging the complementary male connector to establish electrical contact with tracks formed on the complementary male connector.

En référence aux figures 3, 4 et 9, la première partie 1 supporte un circuit imprimé présentant des pistes électriques connectées d'une part à des contacts autodénudants 11 (appelés également "Contacts à Déplacement d'Isolant" ou IDC) soudés sur le circuit imprimé et d'autre part aux lamelles souples situées dans le logement du connecteur.With reference to Figures 3, 4 and 9 , the first part 1 supports a printed circuit having electrical tracks connected on the one hand to insulation displacement contacts 11 (also called "insulating displacement contacts" or IDC) soldered to the printed circuit and on the other hand to the flexible lamellae located in the connector housing.

De manière bien connue et comme représenté sur les figures 3, 4 et 9, les contacts autodénudants 11 sont, pour un connecteur RJ45, organisés en deux rangées de quatre contacts (comme sur les figures annexées) ou quatre rangées de deux contacts et sont formés de broches comportant chacune une fente apte à recevoir un fil d'un câble et à le dénuder pour établir le contact électrique. Selon l'invention, les contacts autodénudants 11 se dressent suivant un axe parallèle à l'axe principal (A) et perpendiculaire au premier axe de rotation (R1) de la liaison pivot entre les deux parties 1, 2 du connecteur.In a well known manner and as shown on the Figures 3, 4 and 9 , the insulation displacement contacts 11 are, for an RJ45 connector, organized in two rows of four contacts (as in the accompanying figures) or four rows of two contacts and are formed of pins each having a slot adapted to receive a wire of a cable and strip it to establish the electrical contact. According to the invention, the insulation displacement contacts 11 rise along an axis parallel to the main axis (A) and perpendicular to the first axis of rotation (R1) of the pivot connection between the two parts 1, 2 of the connector.

La deuxième partie 2 comporte pour sa part une partie fixe 23 et un organe de verrouillage 22 qui est mobile entre une position d'ouverture et une position de fermeture par rapport à la partie fixe 23.The second part 2 comprises for its part a fixed part 23 and a locking member 22 which is movable between an open position and a closed position relative to the fixed part 23.

La partie fixe 23 comporte un support 20 organisateur des fils du câble constitué d'une pièce plastique moulée formant plusieurs plots définissant entre eux plusieurs fentes 200 constituant chacune un emplacement pour recevoir un fil du câble. Le support 20 comporte deux rangées d'emplacements, avec un emplacement correspondant à chaque contact autodénudant 11 présent sur la première partie 1 du connecteur. Préalablement à leur connexion avec les contacts autodénudants 11, les fils du câble sont répartis sur le support 20 organisateur, chacun bloqué dans une fente 200 de celui-ci.The fixed part 23 comprises a support 20 organizing the son of the cable consisting of a molded plastic part forming a plurality of pads defining between them several slots 200 each constituting a location for receiving a cable wire. The support 20 has two rows of locations, with a location corresponding to each insulation displacement contact 11 present on the first part 1 of the connector. Prior to their connection with the insulation displacement contacts 11, the son of the cable are distributed on the support 20 organizer, each locked in a slot 200 thereof.

Par ailleurs, dans la version STP du connecteur, une pièce métallique 3 (figures 3 et 5) est agencée sur le support 20 organisateur de fils pour recevoir le drain du câble. Cette pièce métallique 3 est en contact électrique avec le corps en matériau métallique de la deuxième partie 2 pour assurer la continuité électrique du drain du câble. Le contact métallique entre le drain et la première partie 1 peut être réalisé via la deuxième partie 2 lorsque celle-ci est refermée sur la première partie 1 ou directement via la pièce 3 qui vient en contact avec la première partie 1 lorsque le connecteur est fermé.Furthermore, in the STP version of the connector, a metal part 3 ( figures 3 and 5 ) is arranged on the wire organizer support 20 to receive the drain of the cable. This metal part 3 is in electrical contact with the metal material body of the second part 2 to ensure the electrical continuity of the cable drain. The metallic contact between the drain and the first part 1 can be achieved via the second part 2 when the latter is closed on the first part 1 or directly via the part 3 which comes into contact with the first part 1 when the connector is closed.

Dans la version UTP du connecteur (figure 9), il faut noter que la partie fixe 23 de la deuxième partie du connecteur est constituée du support 20 de fils et ne comporte donc pas un corps externe supportant le support 20 organisateur de fils comme dans la version STP. La partie fixe 23 et le support 20 organisateur de fils sont donc une même pièce.In the UTP version of the connector ( figure 9 ), it should be noted that the fixed part 23 of the second part of the connector is constituted by the support 20 son and therefore does not include an outer body supporting the support 20 son organizer as in the STP version. The fixed part 23 and the son-arranging support 20 are therefore one and the same piece.

Lorsque l'organe de verrouillage 22 est en position de fermeture, la deuxième partie 2 comporte une ouverture 21 formant le chemin de passage du câble. L'ouverture 21 est formée à l'arrière du connecteur, suivant l'axe principal (A) lorsque le connecteur est fermé. Cette ouverture est réalisée de manière à déboucher entre les deux rangées de plots du support 20 organisateur de fils. Les fils du câble accèdent donc au support 20 organisateur de fils par l'arrière du connecteur. L'ouverture 21 est réalisée de manière à aboutir sensiblement au centre du support 20 organisateur de fils pour faciliter la distribution des fils du câble vers leur fente 200 respective sur le support 20.When the locking member 22 is in the closed position, the second portion 2 has an opening 21 forming the passage path of the cable. The opening 21 is formed at the rear of the connector along the main axis (A) when the connector is closed. This opening is made so as to open between the two rows of pads of the support 20 son organizer. The cable wires thus access the wire organizer 20 from the back of the connector. The opening 21 is made so as to end substantially in the center of the yarn support 20 to facilitate the distribution of the son of the cable to their respective slot 200 on the support 20.

Préférentiellement, l'ouverture 21 est réalisée sous la forme d'une large fente débouchant sur l'extérieur et dont l'embouchure peut être fermée ou ouverte selon la position de l'organe de verrouillage 22. Lorsque l'organe de verrouillage 22 est en position d'ouverture (figures 4 et 9), il est ainsi possible de glisser le câble à travers l'ouverture 21 par une simple translation dans le plan incluant l'axe de l'ouverture.Preferably, the opening 21 is made in the form of a wide slot opening on the outside and whose mouth can be closed or open according to the position of the locking member 22. When the locking member 22 is in the open position ( figures 4 and 9 ), it is thus possible to slide the cable through the opening 21 by a simple translation in the plane including the axis of the opening.

Selon l'invention, l'organe de verrouillage 22 est destiné à venir serrer localement le pourtour du câble contre les bords de l'ouverture 21. L'organe de verrouillage 22 permet de sécuriser et verrouiller le câble sur le connecteur avant la répartition des fils sur le support 20 organisateur de fils. L'organe de verrouillage 22 est par exemple mobile en rotation par rapport à la partie fixe 23 autour d'un second axe de rotation (R2, figure 2) perpendiculaire au premier axe de rotation (R1) et parallèle à l'axe principal (A) lorsque le connecteur est fermé. Le connecteur étant en position ouverte (figures 3, 4 et 9), une fois que le câble est positionné à travers l'ouverture 21, l'organe de verrouillage 22 peut être amené dans sa position de fermeture pour verrouiller le câble sur la deuxième partie 2 du connecteur. Le connecteur étant toujours ouvert, l'installateur peut ensuite séparer les fils du câble et les répartir sur le support 20 organisateur de fils.According to the invention, the locking member 22 is intended to grip the periphery of the cable locally against the edges of the opening 21. The locking member 22 makes it possible to secure and lock the cable on the connector before the distribution of the cables. son on the wire organizer support 20. The locking member 22 is for example rotatable relative to the fixed part 23 about a second axis of rotation (R2, figure 2 ) perpendicular to the first axis of rotation (R1) and parallel to the main axis (A) when the connector is closed. The connector being in the open position ( Figures 3, 4 and 9 ), once the cable is positioned through the opening 21, the locking member 22 can be brought into its closed position to lock the cable on the second part 2 of the connector. With the connector still open, the installer can then separate the wires from the cable and distribute them on the wire organizer.

L'organe de verrouillage 22 comporte par exemple des moyens d'indexation lui permettant de stationner en position d'ouverture.The locking member 22 comprises for example indexing means allowing it to park in the open position.

La deuxième partie 2 du connecteur comporte des moyens de maintien de l'organe de verrouillage 22 en position de fermeture. Dans la version STP du connecteur, ces moyens de maintien se présentent par exemple sous la forme d'un crochet 230 (figure 2) pivotant réalisé sur la partie fixe 23 et d'un élément de fermeture 220 complémentaire (figures 4 et 6) réalisé sur l'organe de verrouillage 22. Le crochet 230 est actionnable en pivotement par l'installateur grâce à un bouton pivotant 231 (figure 2) solidaire du crochet 230. Dans la version UTP du connecteur, les moyens de maintien en position de fermeture de l'organe de verrouillage 22 comportent par exemple un crochet réalisé sur l'organe de verrouillage 22 coopérant avec un organe complémentaire de la partie fixe 23 et pouvant se désengager de cet organe complémentaire par déformation élastique.The second part 2 of the connector comprises means for holding the locking member 22 in the closed position. In the STP version of the connector, these holding means are for example in the form of a hook 230 ( figure 2 ) pivoting made on the fixed part 23 and a complementary closure element 220 ( figures 4 and 6 ) on the locking member 22. The hook 230 is pivotally actuatable by the installer with a pivoting knob 231 ( figure 2 ) In the UTP version of the connector, the holding means in the closed position of the locking member 22 comprise for example a hook formed on the locking member 22 cooperating with a complementary member of the fixed part 23 and can disengage from this complementary member by elastic deformation.

En référence à la figure 6, dans la version STP du connecteur, l'organe de verrouillage 22 comporte par exemple une pièce de serrage 221 montée sur un ressort 222, permettant de serrer le câble contre les bords de l'ouverture 21 tout en s'adaptant à l'épaisseur du câble. Cette pièce pourra par exemple être métallique ou comporter une surface d'appui métallisée sur le câble de manière à faire une reprise annulaire à 360° sur l'écran du câble STP. Dans le connecteur en version UTP, cette pièce de serrage 221 est par exemple remplacée par un élément 223 de serrage en matériau souple de type caoutchouc. La pièce 223 comporte plus précisément une languette en matériau souple qui agit, une fois l'organe de verrouillage 22 fermé, comme un frein sur le câble.With reference to the figure 6 , in the STP version of the connector, the locking member 22 comprises for example a clamping piece 221 mounted on a spring 222, for clamping the cable against the edges of the opening 21 while adapting to the thickness cable. This piece may for example be metallic or have a metallized bearing surface on the cable so as to make a annular recovery 360 ° on the STP cable screen. In the connector in UTP version, this clamping piece 221 is for example replaced by a clamping element 223 of flexible material of rubber type. The piece 223 more specifically comprises a tongue of flexible material which acts, once the locking member 22 closed, as a brake on the cable.

Selon l'invention, le connecteur comporte également un système de fermeture du connecteur pour verrouiller la première partie 1 sur la deuxième partie 2. Ce système est par exemple composé d'un organe de fermeture, par exemple un crochet 12, réalisé sur la première partie 1 et d'un organe de fermeture complémentaire, par exemple une fente 24, réalisée sur la deuxième partie 2. L'invention présente la particularité que l'organe de fermeture de la deuxième partie 2, c'est-à-dire la fente 24, est formé sur l'organe de verrouillage 22. De cette manière, le connecteur ne peut être fermé et verrouillé que lorsque l'organe de verrouillage 22 est lui-même en position de fermeture. Ainsi, l'installateur est incité à d'abord verrouiller le câble sur la deuxième partie 2 du connecteur avant de rabattre cette deuxième partie 2 sur la première partie 1 pour fermer le connecteur. Lorsque le câble est sécurisé sur la deuxième partie 2 du connecteur, l'installateur peut répartir les fils sur le support 20 organisateur de fils en évitant tout risque d'arrachage du câble et tout désengagement intempestif des fils de leurs emplacements sur le support 20. Sur les figures 2 et 8, le connecteur n'est pas fermé car l'organe de verrouillage 22 est resté en position d'ouverture.According to the invention, the connector also comprises a closing system of the connector for locking the first part 1 on the second part 2. This system is for example composed of a closure member, for example a hook 12, made on the first part 1 and a complementary closure member, for example a slot 24, made on the second part 2. The invention has the particularity that the closure member of the second part 2, that is to say the slot 24, is formed on the locking member 22. In this way, the connector can be closed and locked only when the locking member 22 is itself in the closed position. Thus, the installer is prompted to first lock the cable on the second part 2 of the connector before folding this second part 2 on the first part 1 to close the connector. When the cable is secure on the second part 2 of connector, the installer can distribute the son on the son organizer support 20 avoiding any risk of pulling the cable and any inadvertent disengagement of the son of their locations on the support 20. On figures 2 and 8 , the connector is not closed because the locking member 22 has remained in the open position.

Sur les deux versions du connecteur, un bouton 4 peut être prévu pour désengager le crochet 12 de la fente 24 et ainsi ouvrir le connecteur par pivotement de la deuxième partie 2 par rapport à la première partie 1 ou inversement.On both versions of the connector, a button 4 can be provided to disengage the hook 12 of the slot 24 and thus open the connector by pivoting the second part 2 relative to the first part 1 or vice versa.

Le montage d'un connecteur de version STP sur un câble STP ou équivalent est réalisé de la manière suivante :

  • l'installateur ouvre le connecteur en appuyant sur le bouton 4 permettant de faire pivoter le crochet 12,
  • une fois le connecteur ouvert, l'installateur appuie sur le bouton 231 pour désengager le crochet 230 de l'élément de fermeture 220 complémentaire et ouvrir ainsi l'organe de verrouillage 22,
  • le câble dont la gaine externe est dénudée à son extrémité est amené par translation à travers l'ouverture 21 ainsi dégagée,
  • le câble est verrouillé sur la deuxième partie 2 du connecteur en ramenant l'organe de verrouillage 22 dans sa position de fermeture,
  • l'installateur répartit les fils dans les fentes 200 du support 20 organisateur de fils et passe le drain en contact avec la pièce métallique 3 prévue à cet effet,
  • lorsque tous les fils sont correctement répartis, l'installateur arase les extrémités des fils qui dépassent,
  • l'installateur ramène la deuxième partie 2 du connecteur sur la première partie 1 du connecteur de manière à insérer les fils du câble dans les contacts autodénudants 11 qui se dressent sur la première partie 1 en vis-à-vis des emplacements du support 20 organisateur de fils,
  • le connecteur est alors fermé et assemblé sur le câble.
Mounting an STP version connector on an STP cable or equivalent is accomplished as follows:
  • the installer opens the connector by pressing the button 4 to rotate the hook 12,
  • once the connector is open, the installer presses the button 231 to disengage the hook 230 from the complementary closure element 220 and thereby open the locking member 22,
  • the cable whose outer sheath is stripped at its end is conveyed through the opening 21 thus disengaged,
  • the cable is locked on the second part 2 of the connector by bringing the locking member 22 into its closed position,
  • the installer distributes the son in the slots 200 of the support 20 son organizer and passes the drain in contact with the metal part 3 provided for this purpose,
  • when all the wires are correctly distributed, the installer flushes the ends of the wires that protrude,
  • the installer brings the second part 2 of the connector to the first part 1 of the connector so as to insert the wires of the cable in the insulation displacement contacts 11 which stand on the first part 1 opposite the locations of the support 20 organizer of son,
  • the connector is then closed and assembled on the cable.
