Description

La présente invention concerne le domaine technique des dispositifs de connexion autodénudante pour le raccordement de conducteurs électriques gainés.The present invention relates to the technical field of insulation displacement connection devices for connection of sheathed electrical conductors.

Il est connu de réaliser la connexion d'un conducteur électrique gainé, par exemple avec un élément appartenant à un bloc de jonction, à l'aide d'une connexion autodénudante. Le dispositif permettant cette connexion autodénudante comprend une mâchoire électriquement conductrice comportant une fente de largeur correspondant sensiblement au diamètre du conducteur électrique et dont les bords acérés sont destinés, lors de l'introduction du conducteur dans l'étrier suivant l'axe de la fente, à inciser la gaine isolante pour permettre un contact électrique entre le conducteur et l'étrier. L'étrier est monté dans un support isolant comportant lui-même une fente qui est alignée avec la fente de l'étrier, et qui assure le passage du conducteur avec serrage de la gaine de celui-ci. Si la mâchoire assure le maintien du conducteur, le maintien et la tenue mécanique sont améliorés par le serrage de la gaine isolante dans la fente ménagée dans le support isolant.It is known to make the connection of an electrical conductor sheathed, for example with an element belonging to a terminal block, using an insulation displacement connection. The device allowing this insulation displacement connection includes an electrically operated jaw conductive with a slot of substantially corresponding width to the diameter of the electrical conductor and whose sharp edges are intended, during the introduction of the conductor into the stirrup along the axis of the slot, to incise the insulating sheath to allow electrical contact between the conductor and the stirrup. The bracket is mounted in an insulating support itself having a slot which is aligned with the slot in the caliper, and which ensures the passage of the conductor with tightening of the sheath thereof. Yes the jaw provides driver support, support and handling mechanics are improved by tightening the insulating sheath in the slot formed in the insulating support.

Cette configuration donne une très bonne tenue aux vibrations et à la traction du conducteur le long de son axe. Toutefois, dans le cas d'une traction dans la direction de la fente, et avec des câbles possédant une gaine isolante de nature particulière, on peut parvenir à un arrachement du câble conducteur.This configuration gives very good resistance to vibrations and the driver's traction along its axis. However, in the case traction in the direction of the slot, and with cables having an insulating sheath of a particular nature, it is possible to achieve a tearing conductor cable.

Le but de l'invention est de fournir un dispositif de connexion autodénudante pour un conducteur électrique gainé, du type précité, et dans lequel la tenue à l'arrachement du conducteur dans la direction de la fente est améliorée.The object of the invention is to provide a connection device insulation displacement insulation for a sheathed electrical conductor of the aforementioned type, and in which the conductor resistance to tearing in the direction of the slot is improved.

A cet effet, le bloc de raccordement autodénudant pour la connexion d'au moins un câble électrique qui comprend une âme conductrice entourée d'une gaine isolante, du type comprenant :

  • une pièce d'interconnexion pourvue d'au moins une mâchoire de dénudage et de raccordement formée par un corps tubuiaire présentant, dans une face, une fente de dénudage et de retenue destinée à inciser la gaine isolante jusqu'à l'âme conductrice du câble pour connecter et retenir l'âme conductrice,
  • et un boítier isolant définissant au moins une chambre de raccordement à l'intérieur de laquelle est disposée la mâchoire dénudante et qui présente, dans une paroi située en regard de la fente de dénudage, une fente de serrage destinée à pincer la gaine isolante du câble.
For this purpose, the insulation displacement connection block for the connection of at least one electric cable which comprises a conductive core surrounded by an insulating sheath, of the type comprising:
  • an interconnection piece provided with at least one stripping and connection jaw formed by a tubular body having, in one face, a stripping and retaining slot intended to cut the insulating sheath up to the conductive core of the cable to connect and hold the conductive core,
  • and an insulating housing defining at least one connection chamber inside which the stripping jaw is disposed and which has, in a wall located opposite the stripping slot, a clamping slot intended to pinch the insulating sheath of the cable .

Selon l'invention, le bloc de raccordement est caractérisé en ce que la fente de serrage est en partie au moins décalée latéralement par rapport à la fente de dénudage.According to the invention, the connection block is characterized in that that the clamping slot is at least partially offset laterally by compared to the stripping slot.

Suivant l'importance de l'effort de maintien recherché, il est possible de mettre en oeuvre ces différentes configurations, soit de façon isolée soit suivant les différentes combinaisons envisageables.Depending on the size of the maintenance effort sought, it is possible to implement these different configurations, either isolated either according to the various possible combinations.

Selon une caractéristique de l'invention, l'axe de la fente de serrage est parallèle à l'axe de la mâchoire de dénudage et décalé latéralement par rapport à celui-ci. Ainsi, le conducteur suit un parcours, entre l'intérieur de l'étrier et l'extérieur du support isolant qui n'est pas une droite mais présente la forme un S très ouvert, ce qui favorise le maintien du câble et renforce la résistance à la traction du raccordement effectué au moyen du bloc conforme à l'invention.According to a characteristic of the invention, the axis of the slot clamping is parallel to the axis of the stripping jaw and offset laterally with respect to it. So the driver follows a route, between the inside of the stirrup and the outside of the insulating support which is not a straight but has a very open S shape, which helps maintain of the cable and strengthens the tensile strength of the connection made to the means of the block according to the invention.

Selon une autre caractéristique de l'invention, la fente de serrage est inclinée et son inclinaison est telle que la zone de la fente de serrage servant au passage du conducteur, en position de connexion, est décalée latéralement par rapport à la zone de la fente de dénudage recevant le conducteur dans cette même position de connexion. Dans ce cas encore il s'agit de donner au conducteur une forme qui n'est pas rectiligne afin de favoriser sa résistance à l'arrachement.According to another characteristic of the invention, the slot clamping is inclined and its inclination is such that the area of the slot clamp used for the conductor passage, in connection position, is laterally offset from the area of the receiving stripping slot the conductor in this same connection position. In this case again this is to give the driver a shape that is not straight in order to promote its resistance to tearing.

Conformément à une autre caractéristique de l'invention, la fente de serrage présente un rétrécissement local qui est de préférence mais non nécessairement situé à proximité de l'extrémité de la fente servant à l'introduction du conducteur.In accordance with another characteristic of the invention, the tightening slot has a local narrowing which is preferably but not necessarily located near the end of the slot used for the introduction of the conductor.

Ce rétrécissement local de la fente de serrage définit alors un obstacle destiné à s'opposer à un arrachement du câble raccordé dans la direction de la fente.This local narrowing of the clamping slot then defines a obstacle intended to oppose a tearing of the cable connected in the direction of the slot.

Avantageusement, dans la zone du rétrécissement la largeur de la fente de serrage est inférieure à sa largeur sur le reste de sa longueur.Advantageously, in the narrowing zone the width of the clamping slot is less than its width over the rest of its length.

Afin d'améliorer encore la résistance à l'arrachement dans la direction de la fente, le rétrécissement de la fente ménagée dans le support isolant est décalé latéralement par rapport à l'axe de la fente sur le reste de sa longueur, de manière à définir une sorte de chicane.In order to further improve the pullout resistance in the direction of the slot, the narrowing of the slot in the support insulation is offset laterally with respect to the axis of the slot on the rest of its length, so as to define a kind of baffle.

Suivant une première possibilité, le rétrécissement local de la fente ménagée dans le support isolant est obtenu par conformation du support isolant lors du moulage de celui-ci.According to a first possibility, the local narrowing of the slot in the insulating support is obtained by conformation of the insulating support during molding thereof.

Suivant une autre possibilité, le rétrécissement local de la fente ménagée dans le support isolant est obtenu par fixation sur le support d'une pièce réalisée indépendamment de celui-ci.Alternatively, local narrowing of the slit formed in the insulating support is obtained by fixing to the support of a piece produced independently of it.

Selon l'invention, le maintien en position du câble électrique résulte, d'une part, du pincement de l'âme conductrice au niveau de la fente de la mâchoire de dénudage et, d'autre part, d'une pression exercée sur la gaine isolante entourant l'âme conductrice du câble au niveau de la fente de serrage du boítier isolant. Ces deux effets de pincement et de serrage sont de plus accentués par la configuration au moins partiellement décalée des fentes de dénudage et de serrage.According to the invention, keeping the electric cable in position results, on the one hand, from the pinching of the conductive core at the level of the stripping jaw slot and, on the other hand, exerted pressure on the insulating sheath surrounding the conductive core of the cable at the insulating housing clamping slot. These two effects of pinching and tightening are further accentuated by the configuration at least partially offset from the stripping and tightening slots.

L'invention vise également à améliorer l'immobilisation du câble raccordé assurée par la fente de serrage du boítier isolant.The invention also aims to improve the immobilization of the cable connected provided by the clamping slot of the insulating housing.

Ainsi, selon une autre caractéristique de l'invention, la fente de serrage est délimitée par deux éléments de paroi du boítier dont un premier élément, dit d'appui, présente une épaisseur supérieure à celle du second élément, dit de serrage. De manière préférée mais non strictement nécessaire, l'élément d'appui définit celui des deux bords de la fente de serrage situé le plus proche d'un plan axial de symétrie de la fente de dénudage.Thus, according to another characteristic of the invention, the slot of tightening is delimited by two wall elements of the housing, a first of which element, called support, has a thickness greater than that of the second element, called tightening. Preferably but not strictly necessary, the support element defines that of the two edges of the slot tightening located closest to an axial plane of symmetry of the slot stripping.

Selon une autre caractéristique préférée de l'invention, l'élément de serrage est élastiquement déformable et présente une rigidité inférieure à celle de l'élément d'appui. Ainsi, l'élément de serrage vient plaquer, contre l'élément d'appui, le câble engagé dans la fente de serrage.According to another preferred characteristic of the invention, the element clamp is elastically deformable and has lower rigidity to that of the support element. Thus, the clamping element is pressed down, against the support element, the cable engaged in the clamping slot.

Selon une autre caractéristique de l'invention, l'élément de serrage est conformé pour présenter une rigidité qui augmente au fur et à mesure de l'éloignement par rapport à l'extrémité d'introduction de la fente de serrage. Ainsi, l'élément de serrage présente une rigidité maximale dans une région située à l'opposé de l'extrémité d'introduction de la fente de serrage, et destinée à recevoir le câble électrique en position de connexion.According to another characteristic of the invention, the element of tightening is shaped to present a rigidity which increases as measurement of the distance from the insertion end of the slot Clamping. Thus, the clamping element has maximum rigidity in a region opposite the insertion end of the slot clamping, and intended to receive the electric cable in connection position.

Selon une autre caractéristique de l'invention, l'élément de serrage est solidaire d'une paroi latérale du boítier isolant. De manière préférée mais non strictement nécessaire, la partie de la paroi latérale, portant l'élément de serrage, présente une face extérieure concave destinée à favoriser la déformation élastique de l'élément de serrage et de la paroi le portant lors du passage du conducteur gainé.According to another characteristic of the invention, the element of tightening is integral with a side wall of the insulating housing. So preferred but not strictly necessary, the part of the side wall, carrying the clamping element, has a concave outer face intended to favor the elastic deformation of the clamping element and the wall carrying it during the passage of the sheathed conductor.

Selon une caractéristique préférée, la partie de la paroi latérale, portant l'élément de serrage, est conformée de manière à pouvoir se déformer lors de l'introduction du câble à raccorder sans augmenter, pendant cette phase d'introduction, l'épaisseur nominale du boítier isolant.According to a preferred characteristic, the part of the side wall, carrying the clamping element, is shaped so that it can be deform when introducing the cable to be connected without increasing, during this introduction phase, the nominal thickness of the insulating housing.

Cette caractéristique avantageuse de l'invention permet, lors de la mise en oeuvre de plusieurs dispositifs, conformes à l'invention, disposés les uns à côté des autres, d'éviter tout désordre dans la juxtaposition lors de la mise en place des conducteurs à raccorder. En effet, dans la mesure où la paroi latérale se déforme lors du passage du conducteur en restant dans l'encombrement nominal du boítier, elle ne vient pas exercer de contraintes sur le boítier adjacent dont le positionnement ne se trouve donc pas perturbé par le raccordement du câble électrique.This advantageous characteristic of the invention allows, during the implementation of several devices, in accordance with the invention, arranged next to each other, to avoid any disorder in the juxtaposition during the installation of the conductors to be connected. Indeed, to the extent where the side wall deforms when the conductor passes while remaining in the nominal size of the housing, it does not exercise constraints on the adjacent housing whose positioning is therefore not not disturbed by the connection of the electric cable.

Selon une autre caractéristique de l'invention, afin d'éviter une extraction intempestive du câble raccordé, l'élément d'appui présente, au niveau de l'extrémité d'introduction de la fente de serrage, un élément saillant définissant un rétrécissement local de la fente de serrage.According to another characteristic of the invention, in order to avoid a untimely extraction of the connected cable, the support element present, at level of the insertion end of the clamping slot, one element protruding defining a local narrowing of the clamping slot.

Selon une autre caractéristique de l'invention, afin de rendre plus aisée l'introduction du câble à raccorder, la partie de la paroi du boítier, portant l'élément de serrage situé en regard de l'élément saillant, est amincie.According to another characteristic of the invention, in order to make easier the introduction of the cable to be connected, the part of the wall of the housing, carrying the clamping element located opposite the projecting element, is thinned.

Dans le même sens et selon une autre caractéristique de l'invention, la face intérieure de la paroi latérale du boítier portant l'élément de serrage possède une région concave située en regard de l'élément saillant.Along the same lines and according to another characteristic of the invention, the inner face of the side wall of the housing carrying the element clamp has a concave region located opposite the element projecting.

Selon une autre caractéristique de l'invention, l'élément de serrage présente un renfort situé en regard de l'élément saillant.According to another characteristic of the invention, the element of clamping has a reinforcement located opposite the projecting element.

Selon une autre caractéristique, le corps de la mâchoire possède une section droite sensiblement en "C".According to another characteristic, the body of the jaw has a cross section substantially at "C".

Selon une caractéristique préférée de l'invention, le corps de la mâchoire présente une section droite transversale sensiblement polygonale qui comprend une âme à partir de laquelle s'étendent deux branches sensiblement parallèles qui possèdent, à l'opposé de l'âme, chacune un bras dont les extrémités en regard définissent les bords de la fente de dénudage. De manière préférée, les bras convergent l'un vers l'autre et à l'opposé de l'âme du corps de la mâchoire de dénudage. Cette caractéristique de l'invention permet de renforcer l'efficacité de la mâchoire de dénudage notamment dans sa fonction de maintien et de retenue du câble électrique.According to a preferred characteristic of the invention, the body of the jaw has a substantially polygonal cross section which includes a soul from which two branches extend substantially parallel which, opposite the core, each have a arms whose opposite ends define the edges of the slit stripping. Preferably, the arms converge towards each other and at the opposite of the core from the body of the stripping jaw. This characteristic of the invention makes it possible to reinforce the efficiency of the jaw stripping particularly in its function of maintaining and retaining the electric cable.

    • Various other characteristics of the invention will emerge from the description below, made with reference to the accompanying drawings which illustrate various non-limiting embodiments of the subject of the invention.
  • Figure 1 is a partial elevational view of a connection device according to the invention.
  • Figure 2 is a front view of the side of the introduction of the conductor.
  • Figure 3 is a cross-sectional view along line III-III of Figure 1.
  • Figure 4 is a view showing another embodiment of a device according to the invention.

    • Comme le montrent les figures 1 et 2, un dispositif de jonction ou de raccordement selon l'invention, désigné dans son ensemble par la référence 1, comprend une pièce d'interconnexion 2 en matériau électriquement conducteur disposée dans un boítier 3 en matériau isolant.As shown in Figures 1 and 2, a joining device or connection according to the invention, designated as a whole by the reference 1, includes an interconnection piece 2 made of material electrically conductive disposed in a housing 3 of insulating material.

    La pièce d'interconnexion 2 est pourvue d'au moins une mâchoire de dénudage et de raccordement 4. Selon l'exemple illustré, il doit être considéré que la pièce d'interconnexion 2 présente, à l'opposé de la mâchoire de dénudage 4 illustrée, une deuxième mâchoire de dénudage non représentée.The interconnection piece 2 is provided with at least one stripping and connection jaw 4. According to the example illustrated, it must be considered that the interconnection piece 2 has, opposite to the stripping jaw 4 illustrated, a second stripping jaw not shown.

    Comme cela ressort de la figure 3, la mâchoire de dénudage est formée par un corps tubulaire 5 présentant, dans une face, une fente de dénudage et de retenue 6 destinée à inciser la gaine isolante 7 d'un câble électrique 8 jusqu'à l'âme conductrice 9 du câble pour connecter et retenir cette âme conductrice 9.As shown in Figure 3, the stripping jaw is formed by a tubular body 5 having, in one face, a slot stripping and retaining 6 intended to incise the insulating sheath 7 of a cable electric 8 to the conductive core 9 of the cable to connect and retain this conductive core 9.

    De manière préférée, la mâchoire 4 présente une section droite transversale polygonale qui comprend une âme 10 à partir de laquelle s'étendent deux branches 11 sensiblement parallèles. Chaque branche 11 possède, à l'opposé de l'âme 10, un bras 12 dont l'extrémité libre définit un bord 13 de la fente de dénudage et de retenue 6. Il doit être noté que les bords 13 sont situés de part et d'autre d'un plan axial P1 de symétrie du corps de la mâchoire de dénudage 4. De manière préférée mais non strictement nécessaire de réalisation de l'invention, les bras 12 convergent l'un vers l'autre, dans une direction opposée à l'âme 10. Cette caractéristique de l'invention permet d'améliorer l'efficacité de la retenue du câble électrique 8 lors de sa mise en place dans la fente de dénudage et de retenue 6.Preferably, the jaw 4 has a cross section polygonal transverse which comprises a core 10 from which extend two branches 11 substantially parallel. Each branch 11 has, opposite the core 10, an arm 12 whose free end defines an edge 13 of the stripping and retaining slot 6. It should be noted that the edges 13 are located on either side of an axial plane P1 of symmetry of the body of the stripping jaw 4. Preferably but not strictly necessary for carrying out the invention, the arms 12 converge towards each other, in a direction opposite to the core 10. This characteristic of the invention improves the efficiency of the restraint electric cable 8 when it is placed in the stripping slot and retainer 6.

    Comme cela ressort des figures 1 et 3, le boítier isolant 3 définit une chambre de raccordement 15 à l'intérieur de laquelle est disposée la mâchoire de dénudage 4. La chambre de dénudage 15 présente alors, dans une paroi située en regard de la fente de dénudage 6, une fente de serrage 16 destinée au passage du câble électrique 8 lors de son raccordement à la mâchoire 4.As shown in Figures 1 and 3, the insulating housing 3 defines a connection chamber 15 inside which the stripping jaw 4. The stripping chamber 15 then has, in a wall located opposite the stripping slot 6, a clamping slot 16 intended for the passage of the electric cable 8 when it is connected to the jaw 4.

    Il doit être noté que le boítier isolant 3 présente, au niveau d'une extrémité d'introduction 17 de la fente de serrage 16, une ouverture 18 pour la mise en place du câble 8 à l'aplomb des fentes de dénudage 6 et de serrage 16 avant son engagement dans ces deux fentes de dénudage 6 et de serrage 16 par un mouvement de translation parallèle à l'axe Δ de la fente de dénudage dans le sens de la flèche F1.It should be noted that the insulating housing 3 has, at the level an insertion end 17 of the clamping slot 16, an opening 18 for the installation of the cable 8 directly above the stripping slots 6 and tightening 16 before its engagement in these two stripping slots 6 and clamping 16 by a translational movement parallel to the axis Δ of the stripping slot in the direction of arrow F1.

    Selon la forme préférée de réalisation illustrée aux figures 1 à 3, l'axe Δ' de la fente de serrage 16 est parallèle à l'axe Δ de la fente de dénudage et se trouve décalé latéralement par rapport à cette dernière, en vue de face du boítier comme cela ressort plus particulièrement de la figure 2. Cette disposition particulière des fentes de dénudage 6 et de serrage 16 impose, au câble électrique raccordé, une conformation en S favorable à une bonne immobilisation du câble électrique.According to the preferred embodiment illustrated in FIGS. 1 to 3, the axis Δ 'of the clamping slot 16 is parallel to the axis Δ of the slot stripping and is offset laterally with respect to the latter, in front view of the housing as shown more particularly in the figure 2. This particular arrangement of the stripping and tightening slots 6 requires an S-shaped conformation favorable to the connected electric cable good immobilization of the electric cable.

    Par ailleurs, selon la forme préférée de réalisation illustrée, la fente de serrage est délimitée par deux éléments de paroi 20, 21 du boítier 3 définissant chacun un bord de la fente de serrage. Chacun des deux éléments 20, 21 assure une fonction et présente un comportement différents afin de permettre la meilleure immobilisation possible du câble électrique gainé engagé dans la fente de serrage 16.Furthermore, according to the preferred embodiment illustrated, the clamping slot is delimited by two wall elements 20, 21 of the housing 3 each defining an edge of the clamping slot. Each of the two elements 20, 21 perform a function and exhibit behavior different to allow the best possible immobilization of the cable sheathed electric engaged in the clamping slot 16.

    Ainsi, la fente de serrage 16 est délimitée par un premier élément de paroi "dit d'appui" 20 en regard duquel est disposé un second élément de paroi "dit de serrage" 21. Thus, the clamping slot 16 is delimited by a first "said support" wall element 20 opposite which a second "clamping" wall element 21.

    Selon l'exemple illustré et de manière préférée, l'élément d'appui 20 définit le bord de la fente de serrage 16 le plus proche d'un plan axial P1 de symétrie de la mâchoire de dénudage 4. Selon l'exemple illustré, l'élément d'appui 20 possède une épaisseur supérieure à celle de l'élément de serrage 21. Cette différence d'épaisseur est alors de préférence associée à une différence de comportement de l'élément d'appui 20 et de l'élément de serrage 21 lors de la mise en place du câble électrique à raccorder. En effet, l'élément de serrage 21 est conformé de manière à se déformer élastiquement lors de l'introduction du câble électrique 8 à raccorder tandis que l'élément d'appui 20 est conformé pour offrir un appui sensiblement rigide au câble électrique 8 qui se trouve alors serré contre l'élément d'appui 20 par l'élément de serrage 21.According to the example illustrated and preferably, the element support 20 defines the edge of the clamping slot 16 closest to a plane axial P1 of symmetry of the stripping jaw 4. According to the example illustrated, the support element 20 has a thickness greater than that of the clamping element 21. This difference in thickness is then preference associated with a difference in behavior of the support element 20 and the clamping element 21 during the installation of the cable electric to be connected. Indeed, the clamping element 21 is shaped so as to deform elastically when the cable is introduced electric 8 to be connected while the support element 20 is shaped to offer a substantially rigid support to the electric cable 8 which is then clamped against the support element 20 by the clamping element 21.

    Afin d'assurer une bonne immobilisation du câble électrique 8 en position de raccordement tout en ne faisant pas obstacle à son introduction dans la fente de serrage, l'élément de serrage 21 est de préférence conformé pour présenter une rigidité qui augmente au fur et à mesure de l'éloignement par rapport à l'extrémité d'introduction 17. La rigidité est alors de préférence maximale dans la zone de la fente de serrage 16 située à l'opposé de l'extrémité d'introduction 17.To ensure good immobilization of the electric cable 8 in the connection position while not obstructing its introduction into the clamping slot, the clamping element 21 is preferably shaped to have a rigidity which increases as measurement of the distance from the insertion end 17. The rigidity is then preferably maximum in the region of the slot clamp 16 located opposite the insertion end 17.

    Selon l'exemple illustré, l'élément de serrage 21 est formé par une nervure solidaire d'une paroi latérale 23 du boítier isolant 3.According to the example illustrated, the clamping element 21 is formed by a rib secured to a side wall 23 of the insulating housing 3.

    Afin de conférer une faculté de déformation à l'élément de serrage 21, la paroi latérale 23 présente, au niveau de sa face extérieure, une région concave 24. Le centre de la région concave 24 se trouve de préférence situé au voisinage de l'extrémité d'introduction 17, de manière à conférer une rigidité croissante à l'élément de serrage 21. En effet, la partie concave 24 confère à la paroi latérale 23 une épaisseur qui augmente au fur et à mesure de l'éloignement par rapport à l'extrémité d'introduction 17.In order to confer a faculty of deformation to the element of clamping 21, the side wall 23 has, at its outer face, a concave region 24. The center of concave region 24 is preferably located near the insertion end 17, so that impart increasing rigidity to the clamping element 21. Indeed, the part concave 24 gives the side wall 23 a thickness which increases as the distance from the insertion end increases 17.

    Selon une caractéristique avantageuse de l'invention, la concavité 24 de la paroi latérale 23 est dimensionnée de manière que, lors de l'introduction d'un câble dans la fente de serrage 17, l'élément de serrage 21 et la paroi latérale 23 se déforment sans augmenter l'épaisseur nominale du boítier isolant 3.According to an advantageous characteristic of the invention, the concavity 24 of the side wall 23 is dimensioned so that, when the introduction of a cable into the clamping slot 17, the element of clamping 21 and the side wall 23 deform without increasing the thickness nominal of the insulating box 3.

    Ainsi, lors de la mise en place d'un câble dans le bloc de jonction conforme à l'invention au fur et à mesure de la progression du câble dans les fentes de dénudage 6 et de serrage 16, l'élément d'appui 20 reste immobile tandis que l'élément de serrage s'efface tout d'abord pour ensuite contraindre la gaine du câble contre l'élément d'appui. Cette contrainte, exercée par l'élément de serrage, induit alors une déformation de la gaine qui flue notamment de part et d'autre de l'étément d'appui définissant une sorte d'étranglement assurant une immobilisation positive et une bonne résistance à la traction du raccordement effectué dans le dispositif conforme à l'invention.So when placing a cable in the block junction according to the invention as the progression of the cable in the stripping and tightening slots 16, the support element 20 remains stationary while the clamping element is first erased to then force the cable sheath against the support element. This stress, exerted by the clamping element, then induces a deformation of the sheath which flows in particular on either side of the support element defining a kind of strangulation ensuring positive immobilization and good tensile strength of the connection made in the device according to the invention.

    Afin d'éviter tout dégagement intempestif du câble raccordé hors des fentes de dénudage 6 et de serrage 16, la fente de dénudage présente, de préférence mais non exclusivement au voisinage de son extrémité d'introduction, un rétrécissement local 25.To avoid inadvertent release of the connected cable outside the stripping and tightening slots 16, the stripping slot present, preferably but not exclusively in the vicinity of its insertion end, local narrowing 25.

    Selon l'exemple illustré, le rétrécissement 25 est défini par un élément saillant 26 faisant partie intégrante de l'élément d'appui 20 et étant situé au niveau de l'extrémité d'introduction 17. Ainsi, l'élément saillant 26 définit le rétrécissement 25 au niveau duquel la fente de serrage 16 présente une largeur inférieure à sa largeur dans la zone 27 située à l'opposé de l'extrémité d'introduction 17 et dans laquelle est situé le câble 8 en position de raccordement.According to the example illustrated, the narrowing 25 is defined by a projecting element 26 forming an integral part of the support element 20 and being located at the insertion end 17. Thus, the element protruding 26 defines the narrowing 25 at which the clamping slot 16 has a width less than its width in the zone 27 located at opposite the insertion end 17 and in which the cable is located 8 in connection position.

    Selon l'exemple illustré, afin de permettre une introduction aisée du câble électrique dans la fente de serrage malgré la présence de l'élément saillant 26, la paroi 23 portant l'élément de serrage 21 est amincie dans sa région située en regard de l'élément 26. A cette fin, la face intérieure de la paroi 23 présente une région concave 28 située en regard de l'élément saillant 26.According to the example illustrated, in order to allow easy introduction of the electric cable in the clamping slot despite the presence of the element projecting 26, the wall 23 carrying the clamping element 21 is thinned in its region located opposite element 26. To this end, the inner face of the wall 23 has a concave region 28 located opposite the element salient 26.

    Par ailleurs, l'élément de serrage 21 présente, de manière préférée mais non strictement nécessaire, un élément de renfort 30 situé en regard de l'élément saillant 26. Cet élément de renfort 30 est destiné, en association avec l'élément saillant 26, à éviter une extraction intempestive de ce dernier hors de la fente de serrage 16.Furthermore, the clamping element 21 has, so preferred but not strictly necessary, a reinforcing element 30 located opposite the projecting element 26. This reinforcing element 30 is intended, in combination with the projecting element 26, to avoid extraction untimely of the latter out of the clamping slot 16.

    Par ailleurs, il doit être noté que l'élément saillant 26 et l'élément de renfort 30 ainsi que les éléments d'appui 20 et de serrage 21 sont tous conformés de manière à ne pas faire obstacle à une introduction du câble électrique dans le boítier et dans la fente de dénudage tout en assurant, à la manière d'un système anti-retour, d'une retenue du câble, une fois ce dernier parfaitement raccordé un peu à la manière d'un système anti-retour. Afin d'accentuer cet effet anti-retour, le rétrécissement 25 est décalé latéralement par rapport à l'axe Δ' de la fente de serrage 16, de sorte que cette dernière présente une conformation en chicane comme le montre la figure 2.Furthermore, it should be noted that the projecting element 26 and the reinforcement element 30 as well as the support 20 and clamping elements 21 are all shaped so as not to obstruct an introduction electrical cable in the housing and in the stripping slot while ensuring, like a non-return system, a cable retention, once the latter perfectly connected a bit like a system anti-return. In order to accentuate this non-return effect, the constriction 25 is laterally offset from the axis Δ 'of the clamping slot 16, so that the latter has a baffle conformation like the shows figure 2.

    Ainsi, le dispositif de raccordement selon l'invention présente une très bonne résistance aux risques de déconnexion intempestive du câble raccordé sous l'effet par exemple de vibrations ou tractions exercées transversalement ou parallèlement aux fentes de dénudage 6 et de serrage 16.Thus, the connection device according to the invention has very good resistance to the risk of inadvertent disconnection of the cable connected under the effect for example of vibrations or pulls exerted transversely or parallel to the stripping and clamping slots 6 16.

    Selon l'exemple illustré précédemment, le décalage de la zone de retenue de la fente de serrage, dans laquelle se situe le câble électrique en position raccordée, est assuré par un décalage latéral complet de l'axe de la fente de serrage 16 par rapport à l'axe de la fente de dénudage 6. Toutefois, conformément à l'invention, ce décalage de la zone de retenue 26 peut être assuré d'une toute autre façon.According to the example illustrated above, the zone offset retaining the tightening slot, in which the electric cable is located in the connected position, is ensured by a complete lateral offset of the axis of the clamping slot 16 relative to the axis of the stripping slot 6. However, in accordance with the invention, this offset from the retention zone 26 can be insured in a completely different way.

    Ainsi, la figure 4 illustre une autre forme de réalisation de l'invention selon laquelle l'axe Δ' de la fente de serrage 16 se trouve incliné par rapport à l'axe Δ de la fente de dénudage et de retenue 6.Thus, FIG. 4 illustrates another embodiment of the invention according to which the axis Δ 'of the clamping slot 16 is inclined relative to the axis Δ of the stripping and retaining slot 6.

    Ainsi, selon cette conformation, la partie 27 de la fente de serrage 16, dans laquelle se situe le câble électrique en position de raccordement, se trouve décalée latéralement par rapport à la fente de dénudage 6.Thus, according to this conformation, the part 27 of the slot of clamping 16, in which the electric cable is located in the position of connection, is laterally offset from the slot stripping 6.

    Bien entendu, l'invention n'est pas limitée aux seules formes d'exécution décrites ci-dessus à titre d'exemples, mais elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que les différentes caractéristiques qui ont été décrites précédemment pourraient être mises en oeuvre isolément ou dans le cadre de combinaisons différentes sans que l'on sorte pour autant du cadre de l'invention.Of course, the invention is not limited to only the forms of execution described above as examples, but it embraces otherwise all variants. This is how the different features that have been described previously could be put in isolation or as part of different combinations without this goes beyond the scope of the invention.
