Description

L'invention concerne un connecteur par déplacement d'isolant pour câble monoconducteur.The invention relates to an insulation displacement connector for a single-core cable.

Actuellement, les connecteurs par déplacements d'isolant pour câble monoconducteur sont largement connus et utilisés dans la technique. Ils comportent le plus souvent un corps de connecteur et au moins un levier mobile en rotation, par rapport au corps de connecteur, et muni d'un orifice de connexion dans lequel le câble est introduit en position d'ouverture. L'orifice de connexion traverse une électrode ou pièce de contact électrique en forme de fourche, et le câble à connecter ayant été introduit dans l'orifice de connexion au travers de l'électrode en forme de fourche, la fermeture du levier provoque l'entraînement du câble entre les branches de l'électrode en forme de fourche en réalisant ainsi un contact électrique par déplacement d'isolant.Currently, connectors by displacement of insulation for single conductor cable are widely known and used in the art. They most often comprise a connector body and at least one lever movable in rotation, relative to the connector body, and provided with a connection orifice in which the cable is introduced in the open position. The connection opening passes through an electrode or electrical contact piece in the form of a fork, and the cable to be connected having been introduced into the connection opening through the fork-shaped electrode, the closing of the lever causes the entrainment of the cable between the branches of the fork-shaped electrode, thereby making electrical contact by displacement of the insulator.

De tels connecteurs ont été décrits par la demande de brevet DE 3 226 128 publiée le 5 Mars 1984. Si de tels connecteurs donnent satisfaction en ce qui concerne la réalisation d'un contact électrique de bonne qualité, ils présentent cependant pour l'utilisateur, c'est-à-dire le réalisateur de circuits électriques, l'inconvénient e provoquer, de par l'entraînement de l'extrémité du câble à connecter et d'une longueur non négligeable de la partie libre de celui-ci, un débattement angulaire important de cette dernière, dans un plan constituant le plan de symétrie longitudinal du connecteur. Ce débattement est sensiblement égal à l'angle de course de rotation du levier et présente l'inconvénient, pour l'utilisateur, de prévoir la longueur du câble à connecter C non pas en fonction de la position fermée du connecteur, position de fonctionnement du connecteur dans laquelle le contact électrique est assuré, mais en fonction de la position ouverte du connecteur, position dans laquelle la longueur de câble à connecter est la plus grande. Cette variation d'orientation et de longueur du câble à connecter C ne permet pas à l'utilisateur réalisateur de circuits de réaliser ces derniers de façon rationnelle, l'utilisateur devant systématiquement tenir compte de la variation d'orientation et de longueur du câble à connecter.Such connectors have been described by patent application DE 3 226 128 published on March 5, 1984. If such connectors are satisfactory with regard to the production of a good quality electrical contact, they nevertheless present for the user, that is to say the producer of electrical circuits, the drawback e cause, by driving the end of the cable to be connected and a non-negligible length of the free part thereof, a clearance significant angularity of the latter, in a plane constituting the longitudinal plane of symmetry of the connector. This travel is substantially equal to the angle of rotation of the lever and has the disadvantage, for the user, to predict the length of the cable to be connected C not according to the closed position of the connector, operating position of the connector in which the electrical contact is ensured, but according to the open position of the connector, position in which the length of cable to be connected is the greatest. This variation in orientation and length of the cable to be connected C does not allow the user making circuits to make these in a rational manner, the user having to systematically take into account the variation in orientation and length of the cable to be connect.

L'invention a pour objet de remédier aux inconvénients précités par la mise en oeuvre d'un connecteur par déplacement d'isolant dans lequel la seule extrémité du câble introduite dans l'orifice de connexion est soumise à une variation d'orientation.The object of the invention is to remedy the aforementioned drawbacks by using a connector by displacement of insulation in which the only end of the cable introduced into the connection orifice is subjected to a variation in orientation.

Un autre objet de la présente invention est la mise en oeuvre d'un connecteur par déplacement d'isolant dans lequel la variation d'orientation de la partie libre du câble à connecter est supprimée lors du passage de la position ouverte à la position fermée du levier de connexion.Another object of the present invention is the implementation of a connector by displacement of insulator in which the variation in orientation of the free part of the cable to be connected is eliminated when passing from the open position to the closed position of the connection lever.

Un autre objet de la présente invention est la mise en oeuvre d'un connecteur à déplacement d'isolant dans lequel la tension mécanique exercée sur le câble, celui-ci étant supposé de longueur minimale en position de fermeture du levier de connexion, est pratiquement supprimée, l'utilisateur étant alors en mesure de concevoir et réaliser les circuits électriques correspondants à partir de câbles dont la longueur minimale correspond à la longueur de câble juste nécessaire à la liaison électrique du connecteur en position de fonctionnement, position fermée du levier de connexion.Another object of the present invention is the implementation of an insulation displacement connector in which the mechanical tension exerted on the cable, the latter being assumed to be of minimum length in the closed position of the connection lever, is practically removed, the user then being able to design and produce the corresponding electrical circuits from cables whose minimum length corresponds to the length of cable just necessary for the connection connector electrical in operating position, closed position of connection lever.

Un autre objet de la présente invention est également la mise en oeuvre d'un bornier comportant une pluralité de connecteurs selon l'invention.Another object of the present invention is also the implementation of a terminal block comprising a plurality of connectors according to the invention.

Le connecteur par déplacement d'isolant pour câble monoconducteur objet de l'invention est remarquable en ce qu'il comporte au moins un connecteur élémentaire,formé d'une part,d'un corps de connecteur élémentaire comprenant une pièce de contact à deux branches fixée au corps de connecteur élémentaire et présentant une partie en arc de cercle centrée, en position, par rapport à une direction Δ orthogonale au corps de connecteur élémentaire, et un goulet d'introduction du câble à connecter, fixe par rapport au corps de connecteur élémentaire, et, d'autre part, d'un levier de connexion monté à rotation par rapport à la direction orthogonale, ledit levier comportant une fente en arc de cercle, susceptible d'être engagée ou dégagée de la partie en arc de cercle de la pièce de contact au cours du mouvement de rotation du levier et un orifice mettant en communication la fente avec l'extérieur, ledit levier et l'orifice ménagé dans celui-ci étant agencés de façon que l'orifice soit en vis-à-vis du goulet d'introduction du câble lorsque le levier de connexion est en position ouverte pour permettre par fermeture du levier, après insertion du câble dans l'orifice à travers le goulet d'introduction, le coincement de l'extrémité du câble entre les deux branches de la pièce de contact pour la réalisation d'un contact électrique par déplacement d'isolant, la partie libre du câble étant maintenue en position fixe par le goulet d'introduction.The connector by displacement of insulation for single-conductor cable object of the invention is remarkable in that it comprises at least one elementary connector, formed on the one hand, of an elementary connector body comprising a contact piece with two branches fixed to the elementary connector body and having a part in an arc of a circle centered, in position, with respect to a direction Δ orthogonal to the elementary connector body, and a cable entry chute to be connected, fixed with respect to the connector body elementary, and, on the other hand, a connection lever rotatably mounted relative to the orthogonal direction, said lever comprising a slot in an arc of a circle, capable of being engaged or disengaged from the part in an arc of a circle the contact piece during the rotational movement of the lever and an orifice placing the slot in communication with the outside, said lever and the orifice formed therein being arranged in f with the opening facing the cable entry neck when the connection lever is in the open position to allow the lever to close by inserting the cable into the opening through the entry neck , the jamming of the end of the cable between the two branches of the contact piece for the production of an electrical contact by displacement of insulation, the free part of the cable being held in a fixed position by the insertion neck.

Le connecteur par déplacement d' isolant objet de l'invention trouve application à la réalisation de circuits électriques dans le domaine de la construction électrique, de l'électronique industrielle, de la robotique, notamment, et dans tout domaine où la constance des contraintes mécaniques appliquées aux câbles électriques doit être impérativement assurée.The connector by displacement of insulator object of the invention finds application in the realization of electrical circuits in the field of electrical construction, industrial electronics, robotics, in particular, and in any field where the constancy of mechanical stresses applied to electrical cables must be guaranteed.

Une description du connecteur par déplacement d'isolant pour câble monoconducteur, objet de l'invention, sera tout d'abord donnée en liaison avec les figures 1a, 1b, 1c, 1d.A description of the connector by displacement of insulation for a single-conductor cable, object of the invention, will first be given in conjunction with FIGS. 1a, 1b, 1c, 1d.

Ainsi qu'on le remarquera sur la figure 1a, notamment, le connecteur par déplacement d'isolant objet de l'invention comporte au moins un connecteur élémentaire formé d'un corps de connecteur élémentaire, noté 1, lequel comprend une pièce de contact notée 2, à deux branches, la pièce de contact étant fixée au corps de connecteur élémentaire et présentant une partie en arc de cercle 22, centrée en position par rapport à une position Δ orthogonale au corps de connecteur élémentaire 1. Le corps de connecteur élémentaire 1 comprend en outre un goulet d'introduction 4 du câble C à connecter, le goulet d'introduction 4 étant fixe par rapport au corps de connecteur élémentaire 1.As will be noted in FIG. 1a, in particular, the connector by displacement of insulator object of the invention comprises at least one elementary connector formed by an elementary connector body, denoted 1, which comprises a contact piece denoted 2, with two branches, the contact part being fixed to the elementary connector body and having a part in an arc 22, centered in position relative to a position Δ orthogonal to the elementary connector body 1. The elementary connector body 1 further comprises an insertion neck 4 of the cable C to be connected, the introduction neck 4 being fixed relative to the elementary connector body 1.

Le connecteur élémentaire du connecteur par déplacement d'isolant objet de l'invention comporte également un levier de connexion noté 3, lequel est monté à rotation par rapport à la direction orthogonale Δ . Le levier 3 comporte une fente en arc de cercle, notée 30, susceptible d'être engagée ou dégagée de la partie en arc de cercle 22 de la pièce de contact 2 au cours du mouvement de rotation du levier. Un orifice 31 tenant lieu d'orifice de connexion est ménagé dans le levier de connexion 3 et met en communication la fente 30 avec l'extérieur.The elementary connector of the connector by displacement of insulator object of the invention also comprises a connection lever noted 3, which is rotatably mounted relative to the orthogonal direction Δ. The lever 3 comprises a slot in an arc, denoted 30, capable of being engaged or disengaged from the part in an arc 22 of the contact piece 2 during the rotation movement of the lever. An orifice 31 acting as a connection orifice is formed in the connection lever 3 and places the slot 30 in communication with the outside.

Conformément à un aspect essentiel du connecteur objet de l'invention, le levier 3 et l'orifice 31 ménagé dans le levier, sont agencés de façon que l'orifice 31 soit en vis-à-vis du goulet d'introduction 4 du câble C, lorsque le levier de connexion 3 est en position ouverte. Après insertion du câble C dans l'orifice 31, à travers le goulet d'introduction 4, le câble C,bien entendu, n'ayant pas été dénudé, la fermeture du levier 3 permet de réaliser le coincement du câble entre les branches de la pièce de contact 2 pour la réalisation de contact électrique par déplacement d'isolant, entre l'âme centrale du conducteur C et la pièce de contact 2.In accordance with an essential aspect of the connector which is the subject of the invention, the lever 3 and the orifice 31 formed in the lever, are arranged so that the orifice 31 faces the cable entry opening 4 C, when the connection lever 3 is in the open position. After insertion of the cable C in the orifice 31, through the insertion neck 4, the cable C, of course, not having been stripped, the closing of the lever 3 makes it possible to wedge the cable between the branches of the contact part 2 for making electrical contact by displacement of insulator, between the central core of the conductor C and the contact part 2.

On remarquera que sur la figure 1b, la vue en coupe longitudinale correspond à une position fermée du levier 3, alors que sur la figure 1c, la même vue en coupe longitudinale de la figure 1a, correspond à une position ouverte du levier 3, l'orifice de connexion 31 et le goulet d'introduction 4 étant sensiblement alignés. Le câble C ayant été introduit dans l'orifice de connexion 31 à travers le goulet d'introduction 4 de façon à traverser la pièce de connexion 2, et en particulier la partie en arc de cercle 22 de celle-ci, le rabattement du levier de connexion 3 à partir de la position ouverte de la figure 1c, vers la position fermée de la figure 1b, permet alors de réaliser le contact électrique par déplacement d'isolant, la partie libre du câble C, c'est-à-dire la partie se trouvant à l'extérieur de l'orifice de connexion 31 et du goulet d'introduction 4, étant alors maintenue en position fixe par le goulet d'introduction 4 précité.It will be noted that in FIG. 1b, the view in longitudinal section corresponds to a closed position of the lever 3, while in FIG. 1c, the same view in longitudinal section in FIG. 1a, corresponds to an open position of the lever 3, the connection orifice 31 and the insertion neck 4 being substantially aligned. The cable C having been introduced into the connection orifice 31 through the insertion neck 4 so as to pass through the connection piece 2, and in particular the part in an arc 22 of the latter, the lever being folded down connection 3 from the open position of Figure 1c, to the closed position of Figure 1b, then allows for electrical contact by displacement of insulation, the free part of the cable C, that is to say the part located outside of the connection orifice 31 and of the inlet neck 4, then being held in a fixed position by the aforementioned inlet neck 4.

Sur la figure 1d, on a représenté une vue en perspective de la pièce de connexion 2 celle-ci comportant la partie en arc de cercle 22, formée de deux branches 20 et 21, sensiblement en forme de fourche. La pièce de connexion 2 comporte en outre un ergot de fixation 23, lequel peut être formé par estampage, présentant une élasticité suffisante afin que la pièce de connexion 2 puisse etre introduite dans le corps de connecteur élémentaire 1, au niveau d'une fente ménagée à cet effet, non représentée aux dessins, la pièce de connexion 2 étant ainsi maintenue fixée dans le corps de connecteur 1 par encliquetage. La pièce de connexion 2 peut, de manière classique, être constituée par un bronze au béryllium et la partie en arc de cercle et en particulier les branches 20 et 21 peuvent être revêtues d'un revêtement protecteur, tel qu'un revêtement à l'étain ou analogue.In Figure 1d, there is shown a perspective view of the connecting piece 2 thereof comprising the part in an arc 22, formed of two branches 20 and 21, substantially in the form of a fork. The connection piece 2 further comprises a fixing lug 23, which can be formed by stamping, having sufficient elasticity so that the connection piece 2 can be introduced into the elementary connector body 1, at a slot for this purpose, not shown in the drawings, the connection piece 2 thus being kept fixed in the connector body 1 by snap-fastening. The connecting piece 2 can, in a conventional manner, be constituted by a beryllium bronze and the part in an arc of a circle and in particular the branches 20 and 21 can be coated with a protective coating, such as a coating with the tin or the like.

De manière avantageuse, le corps de connecteur 1 et le levier 3, peuvent être obtenus à partir de matériau plastique tel que matériau polycarbonate ou polyamide, par moulage.Advantageously, the connector body 1 and the lever 3 can be obtained from plastic material such as polycarbonate or polyamide material, by molding.

Conformément à un aspect particulièrement avantageux du connecteur objet de l'invention, le levier 3 est monté à rotation par rapport à la direction orthogonale Δ par l'intermédiaire d'une articulation notée 300, notamment sur la figure 1a. L'articulation 300 est formée par rapport au corps de connecteur élémentaire 1.In accordance with a particularly advantageous aspect of the connector which is the subject of the invention, the lever 3 is mounted for rotation relative to the orthogonal direction Δ by means of an articulation denoted 300, in particular in FIG. 1a. The articulation 300 is formed relative to the elementary connector body 1.

Selon le mode de réalisation non limitatif représenté en figure 1a, l'articulation 300 peut être formée par deux pattes supports de pivotement, notées 103 et 104 sur la figure précitée, les pattes supports étant disposées en vis-à-vis sur le corps de connecteur élémentaire symétriquement par rapport au plan de symétrie longitudinal AA de la figure 1a. Chaque support de pivotement 103, 104, comporte un logement circulaire 1000, en vis-à-vis, le logement circulaire étant centré sur la direction Δ orthogonale au corps de connecteur. Le levier de connexion 3 comporte avantageusement deux bossages cylindriques notés 3000 formant tourillon de même diamètre que les deux logements circulaires 1000 et sont destinés à être engagés dans ces derniers. Bien entendu, les dimensions telles que l'épaisseur et la longueur des pièces de pivotement 103 et 104, compte tenu du matériau constitutif du corps de connecteur élémentaire 1,seront choisies de façon que les pièces supports de pivotement 103 et 104 présentent une certaine élasticité de façon à pouvoir introduire le levier de connexion 3 à rotation, par rapport aux pièces supports de pivotement, les bossages 3000 formant tourillon étant introduits dans les logements 1000 correspondants.According to the nonlimiting embodiment shown in FIG. 1a, the articulation 300 can be formed by two pivoting support legs, denoted 103 and 104 in the aforementioned figure, the support legs being disposed opposite the body of elementary connector symmetrically with respect to the longitudinal plane of symmetry AA of FIG. 1a. Each pivoting support 103, 104 comprises a circular housing 1000, facing one another, the circular housing being centered on the direction Δ orthogonal to the connector body. The connection lever 3 advantageously comprises two cylindrical bosses denoted 3000 forming a pin of the same diameter as the two circular housings 1000 and are intended to be engaged in the latter. Of course, the dimensions such as the thickness and the length of the pivoting parts 103 and 104, taking account of the material constituting the elementary connector body 1, will be chosen so that the pivoting support parts 103 and 104 have a certain elasticity so as to be able to introduce the connection lever 3 in rotation, with respect to the pivoting support parts, the bosses 3000 forming a trunnion being introduced into the corresponding housings 1000.

Un autre mode de réalisation particulièrement avantageux du connecteur à déplacement d'isolant, objet de l'invention, sera décrit en liaison avec les figures 2a et 2b. Dans le mode de réalisation précité, le corps de connecteur élémentaire 1 est avantageusement muni de parois latérales notées 101 et 102, permettant de matérialiser un logement dans lequel le levier 3 de connexion se trouve escamoté en position fermée. Ce mode de réalisation est particulièrement avantageux en vue d'obtenir un degré d'isolation électrique plus important, entre connecteurs élémentaires disposés de manière adjacente selon leurs dimensions transversales, en vue de constituer un connecteur comportant plusieurs connecteurs élémentaires, ou même un bornier. Selon le mode de réalisation précité, l'articulation 300 est alors formée par deux logements circulaires 1000, disposés en vis-à-vis et ménagés dans chaque paroi latérale 101, 102. Le levier comporte, ainsi que décrit précédemment, deux bossages cylindriques 3000 formant tourillon, de même diamètre que les deux logements circulaires 1000 et destinés à être engagés dans ces derniers.Another particularly advantageous embodiment of the insulation displacement connector, object of the invention, will be described in conjunction with FIGS. 2a and 2b. In the aforementioned embodiment, the elementary connector body 1 is advantageously provided with side walls denoted 101 and 102, making it possible to materialize a housing in which the connection lever 3 is retracted in the closed position. This embodiment is particularly advantageous with a view to obtaining a greater degree of electrical insulation, between elementary connectors arranged adjacent to one another along their transverse dimensions, with a view to constituting a connector comprising several elementary connectors, or even a terminal block. According to the aforementioned embodiment, the articulation 300 is then formed by two circular housings 1000, arranged opposite and formed in each side wall 101, 102. The lever comprises, as described above, two cylindrical bosses 3000 forming a pin, of the same diameter as the two circular housings 1000 and intended to be engaged in the latter.

Selon un autre mode de réalisation non limitatif représenté en figure 3, l'un des supports de pivotement, le support de pivotement 103, dans le mode de réalisation représenté, peut avantageusement être remplacé par une paroi latérale, la paroi 102 dans ce même mode de réalisation,ou réciproquement. Le connecteur élémentaire tel que représenté en figure 3 pourra avantageusement être utilisé en vue de réaliser un connecteur bipolaire, un connecteur élémentaire, tel que représenté en figure 3, pouvant etre associé de manière adjacente selon leur dimension latérale avec un autre connecteur élémentaire dans lequel la paroi latérale 103 a été conservée, la paroi latérale 103 étant par rapport au plan de symétrie longitudinale du corps de connecteur élémentaire opposée à la paroi latérale 102, les parois latérales 102 et 103 étant alors mises en contact l'une de l'autre. Ainsi, un connecteur bipolaire présentant de bonnes caractéristiques d'isolation électrique entre les pôles ainsi constitués, peut avantageusement etre réalisé, isolation correspondant à deux épaisseurs des parois latérales 102 et 103.According to another nonlimiting embodiment shown in FIG. 3, one of the supports pivoting, the pivoting support 103, in the embodiment shown, can advantageously be replaced by a side wall, the wall 102 in this same embodiment, or vice versa. The elementary connector as represented in FIG. 3 could advantageously be used with a view to producing a bipolar connector, an elementary connector, as represented in FIG. 3, which can be associated in an adjacent manner according to their lateral dimension with another elementary connector in which the side wall 103 has been preserved, the side wall 103 being relative to the longitudinal plane of symmetry of the elementary connector body opposite the side wall 102, the side walls 102 and 103 then being brought into contact with one another. Thus, a bipolar connector having good electrical insulation characteristics between the poles thus formed, can advantageously be produced, insulation corresponding to two thicknesses of the side walls 102 and 103.

Dans les modes de réalisation précédemment décrits, le levier de connexion 3 comporte avantageusement un corps de levier 34, dont la dimension transversale parallèle à la direction orthogonale Δ au corps de connecteur élémentaire est inférieure à la dimension correspondante du corps de connecteur élémentaire 1 précité. Le levier de connexion 3 comporte en outre un bras de levier 35 s'étendant longitudinalement dans la direction opposée au goulet d'introduction du câble C à connecter.In the embodiments described above, the connection lever 3 advantageously comprises a lever body 34, the transverse dimension of which is parallel to the direction orthogonal Δ to the elementary connector body is less than the corresponding dimension of the aforementioned elementary connector body 1. The connection lever 3 further comprises a lever arm 35 extending longitudinally in the direction opposite to the cable entry neck C to be connected.

En outre, et de manière particulièrement avantageuse, les modes de réalisation précités peuvent etre agencés, ainsi que représenté en figure 1b notamment, de façon que la direction Δ orthogonale au corps de connecteur élémentaire 1, direction autour de laquelle l'articulation est formée, soit contenue dans un plan de symétrie du goulet d'introduction 4 du câble à connecter C. De manière particulièrement avantageuse, l'axe longitudinal D1 du goulet 4, l'axe longitudinal D2 de l'orifice 31 de connexion et la direction Δ orthogonale au corps de connecteur élémentaire 1 sont concourants en un même point. La précédente disposition a pour effet, ainsi qu'on le comprendra en observation de la figure 1b et 1c, de permettre l'introduction du câble à connecter C dans l'orifice de connexion 31 à travers le goulet d'introduction 4,les axes D1 et D2 étant confondus ainsi que représentés en figure 1c, le câble étant introduit bien entendu au-delà de la fente constituée par les deux branches 20 et 21 de la partie en arc de cercle 22 de la pièce de contact 2. Le levier de connexion 3 étant alors manoeuvré pour amener l'ensemble en position fermée, ainsi que représenté en figure 1b, la seule extrémité du câble C située dans l'orifice de connexion 31, est alors soumise à un mouvement de rotation par rapport à l'axe Δ en l'absence de tout mouvement du câble C, au niveau du goulet d'introduction 4, et de la partie libre du câble extérieure au connecteur. La connexion du câble C sur la pièce de connexion 2, est alors effectuée par déplacement d'isolant en l'absence de tout déplacement de la partie libre du câble, du fait du maintien par le goulet d'introduction 4 et de la mise en rotation de la seule extrémité du câble par rapport à l'axe Δ. Bien entendu, la contrainte exercée sur le câble au cours de l'opération de connexion lors de la fermeture du levier s'analyse au plus en une simple traction de très faible valeur exercée selon l'axe D1 du goulet d'introduction 4.In addition, and in a particularly advantageous manner, the abovementioned embodiments can be arranged, as shown in FIG. 1b in particular, so that the direction Δ orthogonal to the elementary connector body 1, direction around which the articulation is formed, is contained in a plane of symmetry of the inlet neck 4 of the cable to be connected C. In a particularly advantageous manner, the longitudinal axis D1 of the neck 4, the longitudinal axis D2 of the connection orifice 31 and the direction Δ orthogonal to the elementary connector body 1 are concurrent at the same point. The previous arrangement has the effect, as will be understood by observing FIG. 1b and 1c, of allowing the introduction of the cable to be connected C into the connection orifice 31 through the insertion neck 4, the axes D1 and D2 being combined as shown in FIG. 1c, the cable being of course introduced beyond the slot formed by the two branches 20 and 21 of the part in an arc of a circle 22 of the contact piece 2. The lever connection 3 then being operated to bring the assembly into the closed position, as shown in FIG. 1b, the only end of the cable C located in the connection orifice 31, is then subjected to a movement of rotation relative to the axis Δ in the absence of any movement of the cable C, at the level of the insertion neck 4, and of the free part of the cable external to the connector. The connection of the cable C to the connection piece 2 is then carried out by displacement of the insulation in the absence of any displacement of the free part of the cable, due to the retention by the neck introduction 4 and the rotation of the single end of the cable relative to the axis Δ. Of course, the stress exerted on the cable during the connection operation when the lever is closed can be analyzed at most by a simple pull of very low value exerted along the axis D1 of the inlet neck 4.

Sur la figure 4, on a représenté un bornier constitué par une pluralité de connecteurs élémentaires adjacents, selon l'invention, le corps de bornier étant de préférence une pièce monobloc moulée. En variante, le bornier peut être réalisé par emboîtement ou encliquetage de connecteurs élémentaires munis à cet effet d'éléments coopérants appropriés. Afin d'assurer la fermeture du dernier connecteur élémentaire d'ordre n sur la figure 4, il est alors possible de prévoir une pièce latérale notée 50, laquelle vient tout naturellement s'emboîter ou s'encliqueter sur des éléments de forme du connecteur élémentaire d'ordre n précité.In Figure 4, there is shown a terminal block constituted by a plurality of adjacent elementary connectors, according to the invention, the terminal block body preferably being a molded one-piece piece. As a variant, the terminal block can be produced by fitting or snap-on of elementary connectors provided for this purpose with suitable cooperating elements. In order to ensure the closing of the last elementary connector of order n in FIG. 4, it is then possible to provide a side piece denoted 50, which quite naturally fits or snaps onto elements of form of the elementary connector of order n above.

Le bornier décrit en relation avec la figure 4, peut bien entendu être utilisé pour la connexion de conducteurs monoconducteurs, les conducteurs monoconducteurs étant des conducteurs monobrins ou multibrins. Mais ils peuvent également être utilisés, si nécessaire pour la connexion de câbles multiconducteurs ou en nappe, pourvu que les dimensions correspondantes, dimensions transversales notamment, soient adaptées en conséquence.The terminal block described in relation to FIG. 4 can of course be used for the connection of single-conductor conductors, the single-conductor conductors being single-strand or multi-strand conductors. However, they can also be used, if necessary for the connection of multi-core or flat cables, provided that the corresponding dimensions, in particular transverse dimensions, are adapted accordingly.

On a ainsi décrit un connecteur par déplacement d'isolant ou câble monoconducteur, particulièrement avantageux en ce que, quelle que soit la position ouverte ou fermée du levier de connexion la longueur du câble à prévoir pour assurer la connexion est sensiblement identique. Cette particularité permet d'assurer à l'utilisateur, un confort et une facilité d'utilisation permettant à celui-ci la réalisation de circuits électriques de manière totalement adaptée.We have thus described a connector by displacement of insulation or single-conductor cable, particularly advantageous in that, whatever the position open or closed of the connection lever the length of the cable to be provided to ensure the connection is substantially identical. This feature makes it possible to provide the user with comfort and ease of use allowing the latter to produce electrical circuits in a completely suitable manner.
