Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

La présente invention concerne de manière générale les connecteurs auto-dénudants qui sont aptes à intervenir sur un conducteur électrique isolé, comportant, autour d'une âme conductrice, une gaine isolante, sans dénudage préalable de son âme conductrice, pour le relier électriquement à un appareillage électrique quelconque ou à d'autres conducteurs électriques isolés.The present invention generally relates to self-stripping connectors which are capable of acting on an insulated electrical conductor comprising, around a conductive core, an insulating sheath, without prior stripping of its conductive core, to electrically connect it to a any electrical apparatus or other insulated electrical conductors.

L'invention concerne, plus particulièrement, un connecteur auto-dénudant comportant d'une part, une partie fixe pourvue d'un organe métallique comportant au moins une fente de connexion et, d'autre part, une partie mobile propre à forcer un conducteur électrique isolé dans cette fente et pourvue à cet effet d'un logement, s'étendant en regard de ladite fente, qui est propre à recevoir le conducteur électrique isolé et qui comporte une première et une seconde parois d'appui adaptées à pousser le conducteur électrique isolé introduit dans le logement, la partie mobile étant montée sur la partie fixe pour être déplacée entre une position d'introduction du conducteur électrique isolé dans la fente de l'organe métallique et une position d'extraction du conducteur électrique isolé hors de ladite fente.The invention relates, more particularly, to a self-stripping connector comprising, on the one hand, a fixed part provided with a metal member having at least one connection slot and, on the other hand, a movable part capable of forcing a conductor. electrical isolated in this slot and provided for this purpose with a housing, extending opposite said slot, which is adapted to receive the insulated electrical conductor and which comprises a first and a second support walls adapted to push the driver electrical insulator introduced into the housing, the movable portion being mounted on the fixed portion to be moved between an insertion position of the insulated electrical conductor in the slot of the metal member and an extraction position of the isolated electrical conductor out of said slot.

ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND

On connaît déjà des documents FR 2 622 362 et FR 2 623 024 des connecteurs auto-dénudants du type précité dans lesquels le logement de la partie mobile, dénommée barillet, propre à recevoir le conducteur électrique isolé, est un passage étroit dont le diamètre est légèrement supérieur à celui du conducteur électrique isolé pour permettre son introduction aisée dans ledit passage, mais dont les parois d'appui adaptées à pousser ledit conducteur électrique isolé sont en permanence rapprochées de ce dernier.Already known from documents FR 2 622 362 and FR 2 623 024 self-stripping connectors of the aforementioned type in which the housing of the movable part, called barrel, adapted to receive the insulated electrical conductor, is a narrow passage whose diameter is slightly greater than that of the insulated electrical conductor to allow its easy introduction into said passage, but whose support walls adapted to push said insulated electrical conductor are permanently close to the latter.

De ce fait, dans ces connecteurs, le conducteur électrique isolé reste en permanence solidaire à déplacement du barillet qui est adapté à prendre seulement deux positions différentes, à savoir la position de connexion dans laquelle il introduit le conducteur électrique isolé dans la fente de l'organe métallique et la position de déconnexion dans laquelle il extrait le conducteur électrique isolé hors de ladite fente.Therefore, in these connectors, the insulated electrical conductor remains permanently fixed to the displacement of the barrel which is adapted to take only two different positions, namely the connection position in which it introduces the isolated electrical conductor into the slot of the metal member and the disconnection position in which it extracts the isolated electrical conductor out of said slot.

Il n'est pas possible alors de connecter séquentiellement plusieurs conducteurs électriques isolés à l'organe métallique de connexion car pour connecter un conducteur électrique isolé après un autre on est obligé de déplacer le barillet depuis sa position de connexion vers sa position de déconnexion ce qui provoque la déconnexion du premier conducteur électrique isolé introduit dans la fente de connexion de l'organe métallique.It is not possible then to sequentially connect several insulated electrical conductors to the metal connecting member because to connect an isolated electrical conductor after another one is obliged to move the barrel from its connection position to its disconnection position which causes the disconnection of the first isolated electrical conductor introduced into the connection slot of the metal member.

Ainsi, dans de tels connecteurs, tous les conducteurs électriques doivent être connectés et/ou déconnectés simultanément ce qui n'est pas forcément aisé pour l'installateur.Thus, in such connectors, all the electrical conductors must be connected and / or disconnected simultaneously, which is not necessarily easy for the installer.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Le but de la présente invention est donc de proposer un nouveau connecteur auto-dénudant qui présente un faible encombrement et qui permet aisément, d'une part, de connecter de manière séquentielle plusieurs conducteurs électriques isolés à un ou plusieurs organes métalliques de connexion, et, d'autre part, de déconnecter simultanément l'ensemble desdits conducteurs électriques isolés connectés.The object of the present invention is therefore to provide a new self-stripping connector which has a small footprint and which makes it easy, on the one hand, to connect sequentially several insulated electrical conductors to one or more metal connecting members, and on the other hand, simultaneously disconnect all of said connected insulated electrical conductors.

Plus particulièrement, l'invention propose un connecteur auto-dénudant tel que défini en introduction, dans lequel la partie mobile est apte à prendre une position intermédiaire entre lesdites positions d'introduction et d'extraction, cette position intermédiaire étant une position d'attente d'insertion du conducteur électrique isolé dans ledit logement, et en ce que les première et seconde parois d'appui dudit logement sont espacées l'une de l'autre d'une distance supérieure à la distance parcourue par ladite partie mobile entre la position d'introduction et la position intermédiaire.More particularly, the invention proposes a self-stripping connector as defined in the introduction, wherein the movable portion is adapted to take an intermediate position between said insertion and extraction positions, this intermediate position being a waiting position. insertion of the insulated electrical conductor into said housing, and in that the first and second support walls of said housing are spaced from each other by a distance greater than the distance traveled by said movable portion between the position of introduction and the intermediate position.

En d'autres termes, dans le connecteur selon l'invention, la première paroi d'appui du logement de la partie mobile est seulement active lors du passage de ladite partie mobile de ladite position intermédiaire d'attente à ladite position d'introduction pour forcer le conducteur électrique dans ladite fente, et la seconde paroi d'appui est seulement active lors du passage de ladite partie mobile de ladite position intermédiaire d'attente à ladite position d'extraction pour pousser ledit conducteur électrique isolé hors de ladite fente.In other words, in the connector according to the invention, the first support wall of the housing of the movable part is only active during the passage of said movable part of said intermediate waiting position to said insertion position for forcing the electrical conductor into said slot, and the second supporting wall is only active during the passage of said movable portion of said standby intermediate position to said extraction position for urging said insulated electrical conductor out of said slot.

Lorsque la partie mobile du connecteur selon l'invention passe de la position d'introduction à la position intermédiaire d'attente aucune des parois d'appui n'agit sur le conducteur électrique isolé qui est engagé à force dans la fente de connexion correspondante de l'organe métallique de la partie fixe.When the mobile part of the connector according to the invention moves from the insertion position to the intermediate position waiting none of the walls support acts on the insulated electrical conductor which is forced into the corresponding connection slot of the metal member of the fixed part.

Ainsi, grâce à l'invention, l'installateur peut, de manière séquentielle, après avoir introduit un premier conducteur électrique isolé dans une fente de connexion de l'organe métallique, déplacer la partie mobile pour la positionner en position intermédiaire d'attente sans toucher à ce premier conducteur et y insérer un deuxième conducteur électrique isolé pour l'engager à force dans une autre fente de connexion de l'organe métallique porté par la partie fixe.Thus, thanks to the invention, the installer can, sequentially, after having introduced a first insulated electrical conductor into a connection slot of the metal member, move the movable part to position it in intermediate waiting position without touching the first conductor and insert a second insulated electrical conductor to force it into another slot connecting the metal member carried by the fixed part.

En préliminaire, on notera que, d'une figure à l'autre, les éléments identiques ou similaires des différents modes de réalisation de l'invention sont référencés par les mêmes signes de référence et ne seront pas décrits à chaque fois.In preliminary, it will be noted that, from one figure to another, the identical or similar elements of the various embodiments of the invention are referenced by the same reference signs and will not be described each time.

Sur les figures 1, 2A et 2B, on a représenté deux variantes d'un connecteur auto-dénudant 100 qui comporte une partie fixe 101 et une partie mobile 120 déplaçable par rapport à la partie fixe 101.FIGS. 1, 2A and 2B show two variants of a self-stripping connector 100 which comprises a fixed part 101 and a mobile part 120 displaceable with respect to the fixed part 101.

La partie fixe 101 est pourvue d'au moins un organe métallique 110 comportant une fente 111 de connexion et la partie mobile 120 est propre à forcer un conducteur électrique isolé (non représenté sur les figures 1 et 2) dans cette fente 111. La partie mobile 120 est pourvue à cet effet d'un logement 121, s'étendant en regard de ladite fente 111, qui est propre à recevoir le conducteur électrique isolé.The fixed portion 101 is provided with at least one metal member 110 having a connecting slot 111 and the movable portion 120 is adapted to force an insulated electrical conductor (not shown in FIGS. 1 and 2) in this slot 111. The portion Mobile 120 is provided for this purpose with a housing 121, extending opposite said slot 111, which is adapted to receive the insulated electrical conductor.

Avantageusement, le connecteur auto-dénudant 100 constitue le fond d'un socle 1 d'un appareillage électrique. Il permet de raccorder les conducteurs électriques en provenance du réseau d'alimentation électrique audit appareillage électrique.Advantageously, the self-stripping connector 100 constitutes the bottom of a base 1 of an electrical equipment. It makes it possible to connect the electrical conductors coming from the power supply network to the electrical equipment.

Ainsi, ici, la partie fixe 101 comporte trois organes métalliques 110 identiques pour la connexion de trois conducteurs électriques isolés, à savoir, un conducteur de phase, un conducteur de neutre et un conducteur de mise à la terre. En correspondance, la partie mobile 120 comporte trois logements 121 identiques propres à recevoir les trois conducteurs de phase, de neutre et de terre à connecter aux trois organes métalliques 110.Thus, here, the fixed portion 101 comprises three identical metal members 110 for connection of three insulated electrical conductors, namely, a phase conductor, a neutral conductor and a grounding conductor. In correspondence, the mobile part 120 comprises three identical housings 121 adapted to receive the three phase, neutral and earth conductors to be connected to the three metal members 110.

Ici, chaque organe métallique 110 constitue une borne de connexion de l'appareillage électrique.Here, each metal member 110 constitutes a connection terminal of the electrical equipment.

Chaque logement 121 de la partie mobile 120 comporte une première et une seconde parois d'appui 121A, 121B ; 121'B adaptées à pousser chaque conducteur électrique isolé introduit dans le logement 121 concerné.Each housing 121 of the movable portion 120 has first and second bearing walls 121A, 121B; 121'B adapted to push each insulated electrical conductor introduced into the housing 121 concerned.

Comme le montrent les figures 6 et 14C, la partie mobile 120 est montée sur la partie fixe 101 pour être déplacée entre une position d'introduction du conducteur électrique isolé C dans la fente 111 de l'organe métallique 110 correspondant (voir figure 6) et une position d'extraction du conducteur électrique isolé C hors de ladite fente (voir figure 14C).As shown in Figures 6 and 14C, the movable portion 120 is mounted on the fixed portion 101 to be moved between an insertion position of the insulated electrical conductor C in the slot 111 of the corresponding metal member 110 (see Figure 6) and an extraction position of the insulated electrical conductor C out of said slot (see Fig. 14C).

En outre, avantageusement, selon l'invention, comme le montrent les figures 3 et 10, la partie mobile 120 est apte à prendre une position intermédiaire entre lesdites positions d'introduction et d'extraction. Cette position intermédiaire est une position d'attente d'insertion du conducteur électrique isolé C dans ledit logement 121 correspondant, et les première et seconde parois d'appui 121A, 121B ; 121'B de chaque logement 121 sont espacées l'une de l'autre d'une distance supérieure à la distance parcourue par ladite partie mobile 120 entre la position d'introduction (voir figure 6) et la position intermédiaire (voir figure 3).In addition, advantageously, according to the invention, as shown in Figures 3 and 10, the movable portion 120 is adapted to take an intermediate position between said insertion and extraction positions. This intermediate position is an insertion waiting position of the insulated electrical conductor C in said corresponding housing 121, and the first and second support walls 121A, 121B; 121'B of each housing 121 are spaced from each other by a greater distance than the distance traveled by said movable portion 120 between the insertion position (see Figure 6) and the intermediate position (see Figure 3) .

Selon les modes de réalisation représentés sur les figures, chaque fente 111 de connexion de chaque organe métallique 110 est allongée selon une portion de cercle autour d'un axe X et ladite partie mobile 120 est montée rotative sur ladite partie fixe 101 autour dudit axe X. En outre, les première et seconde parois d'appui 121A, 121B ; 121'B de chaque logement 121 sont espacées l'une de l'autre d'un secteur angulaire supérieur au secteur angulaire parcouru par ladite partie mobile 120 entre la position d'introduction (voir figure 6) et la position intermédiaire d'attente (voir figure 3).According to the embodiments shown in the figures, each connection slot 111 of each metal member 110 is elongate along a portion of a circle about an axis X and said movable portion 120 is rotatably mounted on said fixed portion 101 about said axis X In addition, the first and second support walls 121A, 121B; 121 'B of each housing 121 are spaced from each other by an angular sector greater than the angular sector traversed by said movable part 120 between the insertion position (see FIG. 6) and the intermediate waiting position ( see Figure 3).

Ici, la partie mobile 120 se présente sous la forme d'un capot recouvrant ladite partie fixe 101, avec une paroi plane 120A bordée d'une paroi latérale 120B, 120C périphérique.Here, the movable portion 120 is in the form of a cover covering said fixed portion 101, with a plane wall 120A bordered by a peripheral side wall 120B, 120C.

La partie fixe 101 présente une forme globalement cylindrique de révolution autour de l'axe X.The fixed part 101 has a generally cylindrical shape of revolution about the axis X.

Selon les modes de réalisation représentés sur les figures 1, 2A et 2B, la face externe 120B de la paroi latérale périphérique de la partie mobile 120 suit le contour polygonal de la face externe 2 du socle 1 de l'appareillage électrique et la face interne 120C de cette paroi latérale périphérique présente une forme cylindrique de révolution autour de l'axe X de manière à s'ajuster étroitement autour de la face externe cylindrique 101A de la partie fixe 101.According to the embodiments shown in Figures 1, 2A and 2B, the outer face 120B of the peripheral side wall of the movable part 120 follows the polygonal contour of the outer face 2 of the base 1 of the electrical equipment and the inner face 120C of this peripheral side wall has a shape cylindrical of revolution about the X axis so as to fit tightly around the cylindrical outer face 101A of the fixed portion 101.

Selon la variante de réalisation représentée sur les figures 15 et 16, la paroi latérale 120'B périphérique de la partie mobile 120' est une paroi cylindrique de révolution qui s'ajuste autour de la partie fixe 101' de sorte qu'elle se place en retrait de la face externe polygonale 2 du socle 1 de l'appareillage électrique.According to the variant embodiment shown in FIGS. 15 and 16, the peripheral side wall 120 'B of the movable part 120' is a cylindrical wall of revolution which fits around the fixed part 101 'so that it is placed recessed from the polygonal outer face 2 of the base 1 of the electrical equipment.

La partie mobile 120 est encliquetée sur la partie fixe 101 et, pour le montage à rotation de la partie mobile 120 sur la partie fixe 101, d'une part, la partie fixe 101 comporte par exemple en son centre un plot 103 percé d'un conduit de montage 103A, et, d'autre part, la paroi plane 120A de la partie mobile 120 porte sur sa face interne, en son centre, un arbre cylindrique 122 destiné à être engagé à rotation libre dans le conduit de montage 103A de la partie fixe 101.The mobile part 120 is snapped onto the fixed part 101 and, for the rotational mounting of the mobile part 120 on the fixed part 101, on the one hand, the fixed part 101 comprises for example in its center a stud 103 pierced with a mounting duct 103A, and, on the other hand, the plane wall 120A of the movable part 120 carries on its inner face, at its center, a cylindrical shaft 122 intended to be engaged in free rotation in the mounting duct 103A of the fixed part 101.

En outre, comme le montre plus particulièrement les figures 2A et 2B, il est prévu des moyens d'indexation des trois positions (position d'introduction, position intermédiaire, position d'extraction) de la partie mobile 120 sur la partie fixe 101. Ces moyens d'indexation comprennent ici, à deux endroits diamétralement opposés de la face externe cylindrique 101A de ladite partie fixe 101, deux séries de trois crans 1A, 1 B, 1C, et, en correspondance sur la partie mobile 120, deux pattes élastiques 123 pourvues chacune d'un bourrelet 123A destiné à coopérer avec les crans 1A, 1B, 1C. Chaque patte élastique 123 est intégrée dans la face interne 120C cylindrique de la paroi latérale périphérique de ladite partie mobile 120 de sorte que le bourrelet 123A qu'elle porte fait saillie de ladite face interne 120C.In addition, as shown more particularly in FIGS. 2A and 2B, there are provided means for indexing the three positions (insertion position, intermediate position, extraction position) of the mobile part 120 on the fixed part 101. These indexing means here comprise, at two diametrically opposite locations of the cylindrical outer face 101A of said fixed part 101, two series of three notches 1A, 1B, 1C, and, in correspondence on the movable part 120, two elastic tabs. 123 each provided with a bead 123A for cooperating with the notches 1A, 1B, 1C. Each resilient tab 123 is integrated into the cylindrical inner face 120C of the peripheral side wall of said movable portion 120 so that the bead 123A it carries projects from said inner face 120C.

Par ailleurs, selon les modes de réalisation représentés sur les figures 1, 2A et 2B, chaque logement 121 de la partie mobile 120 débouche sur la face externe de sa paroi plane 120A.Furthermore, according to the embodiments shown in Figures 1, 2A and 2B, each housing 121 of the movable portion 120 opens on the outer face of its flat wall 120A.

Selon la variante de réalisation du connecteur 100 représentée sur les figures 15 et 16, chaque logement 121' de la partie mobile 120 débouche sur la face externe de sa paroi latérale 120'B périphérique.According to the embodiment of the connector 100 shown in Figures 15 and 16, each housing 121 'of the movable portion 120 opens on the outer face of its peripheral side wall 120'B.

Comme le montre en particulier la figure 1, chaque organe métallique 110 de la partie fixe 101 présente une forme en U avec un dos 110A et deux ailes 110B parallèles en regard, chaque aile 110B comportant au moins une fente 111 de connexion pour la connexion d'un conducteur électrique isolé. Ici, chaque aile 110B comporte deux fentes 111 de connexion parallèles de deux conducteurs électriques isolés différents.As shown in particular in Figure 1, each metal member 110 of the fixed portion 101 has a U-shape with a back 110A and two flanges 110B parallel opposite, each flange 110B having at least one slot 111 connection for the connection of an isolated electrical conductor. Here each wing 110B has two slots 111 of parallel connection of two different insulated electrical conductors.

Ainsi, selon l'exemple représenté, chaque organe métallique 110 comporte, pour la connexion d'un conducteur électrique isolé C, une paire de fentes 111 de connexion parallèles prévues respectivement dans les deux ailes 110B parallèles en regard dudit organe métallique 110 de sorte que ce dernier est apte à établir à au moins deux endroits différents le long dudit conducteur électrique C le contact avec son âme conductrice C1 (voir figure 9).Thus, according to the example shown, each metal member 110 comprises, for the connection of an insulated electrical conductor C, a pair of parallel connection slots 111 respectively provided in the two parallel flanges 110B facing said metal member 110 so that the latter is able to establish at at least two different locations along said electrical conductor C contact with its conductive core C1 (see Figure 9).

Comme le montrent les figures 1, 2B et 15, la partie fixe 101 ; 101' comporte des logements 102 qui accueillent les organes métalliques 110. Lesdits logements 102 sont séparés les uns des autres par des parois 102A ou des nervures contre lesquelles s'appuient les dos 110A des organes métalliques 110 (voir figure 5).As shown in Figures 1, 2B and 15, the fixed portion 101; 101 'comprises housing 102 which accommodate the metal members 110. The said housing 102 are separated from each other by walls 102A or ribs against which the back 110A of the metal members 110 (see Figure 5).

Le fond de chaque logement de la partie fixe 101, 101' forme le fond de chaque logement 121 de ladite partie mobile 120.The bottom of each housing of the fixed part 101, 101 'forms the bottom of each housing 121 of said movable part 120.

Ainsi, selon les modes de réalisation des figures 1 et 2B, les logements 102 de la partie fixe 101 sont des logements axiaux qui sont répartis autour de l'axe X et qui débouchent sur la face plane de ladite partie fixe 101 opposée au socle 1 et faisant face à la paroi plane 120A de ladite partie mobile 120. Selon le mode de réalisation des figures 15 et 16, les logements de la partie fixe 101 sont prévus dans la paroi latérale cylindrique de celle-ci.Thus, according to the embodiments of FIGS. 1 and 2B, the housings 102 of the fixed part 101 are axial housings which are distributed around the X axis and which open out onto the flat face of said fixed part 101 opposite to the base 1 and facing the plane wall 120A of said movable portion 120. According to the embodiment of Figures 15 and 16, the housings of the fixed portion 101 are provided in the cylindrical side wall thereof.

Par ailleurs, comme le montrent les figures, la première paroi d'appui 121A de chaque logement 121 de la partie mobile 120 comporte une forme en U dont le fond fait face à l'embouchure d'une paire de fentes 111 de connexion de l'organe métallique 110 correspondant et forme un berceau de réception du conducteur électrique isolé. Ici, pour chaque logement 121 de la partie mobile 120, la première paroi d'appui 121A comporte deux U faisant face aux embouchures des deux paires de fentes 111 de l'organe métallique 110 correspondant.Furthermore, as shown in the figures, the first support wall 121A of each housing 121 of the movable portion 120 has a U-shaped whose bottom faces the mouth of a pair of slots 111 connecting the corresponding metal member 110 and forms a cradle for receiving the isolated electrical conductor. Here, for each housing 121 of the movable portion 120, the first support wall 121A comprises two U facing the mouths of the two pairs of slots 111 of the corresponding metal member 110.

Les logements 102 de la partie fixe 101 logent lesdites premières parois d'appui 121A des logements 121 de la partie mobile 120.The housings 102 of the fixed part 101 house said first bearing walls 121A of the housings 121 of the mobile part 120.

La seconde paroi d'appui 121 B, 121'B de chaque logement 121 de la partie mobile 120 est formée par la tranche de l'ouverture par laquelle ledit logement 121 débouche à l'extérieur de ladite partie mobile 120.The second support wall 121B, 121'B of each housing 121 of the mobile part 120 is formed by the edge of the opening through which said housing 121 opens out of said movable part 120.

Selon le mode de réalisation du connecteur représenté sur la figure 1, ladite seconde paroi d'appui 121 B est une paroi droite.According to the embodiment of the connector shown in Figure 1, said second support wall 121 B is a right wall.

Selon les deux autres modes de réalisation du connecteur représentés sur les autres figures, la seconde paroi d'appui 121'B de chaque logement 121 de la partie mobile 120 comporte une forme en U dont le fond forme un berceau de réception du conducteur électrique isolé C. En particulier, pour chaque logement 121 de la partie mobile 120, la seconde paroi d'appui 121A comporte deux U faisant face aux dos des deux paires de fentes 111 de l'organe métallique 110 correspondant.According to the other two embodiments of the connector shown in the other figures, the second support wall 121'B of each housing 121 of the movable part 120 has a U-shape whose bottom forms a cradle for receiving the isolated electrical conductor C. In particular, for each housing 121 of the movable portion 120, the second support wall 121A comprises two U facing the backs of the two pairs of slots 111 of the corresponding metal member 110.

Avantageusement la partie mobile 120 est réalisée d'une seule pièce par moulage d'une matière plastique rigide et la partie fixe 101 vient de formation avec le socle 1 pour former une ensemble monobloc. La partie fixe 101 et le socle 1 de l'appareillage électrique sont également, préférentiellement, réalisés par moulage d'une matière plastique rigide.Advantageously, the movable portion 120 is made in one piece by molding a rigid plastic material and the fixed portion 101 is formed with the base 1 to form a one-piece assembly. The fixed part 101 and the base 1 of the electrical equipment are also, preferably, made by molding a rigid plastic material.

En référence aux figures 3 à 13 et aux figures 14A à 14C nous allons décrire le fonctionnement en connexion et en déconnexion du connecteur selon l'invention.With reference to FIGS. 3 to 13 and FIGS. 14A to 14C, we will describe the operation in connection and disconnection of the connector according to the invention.

Sur la figure 3 on a représenté le connecteur auto-dénudant 100 avec sa partie mobile 120 dans sa position intermédiaire d'attente. Dans cette position, la paroi latérale 120B de la partie mobile 120 est décalée par rapport à celle dudit socle 1. Comme le montre les figures 4 et 5, dans cette position de la partie mobile 120, l'installateur peut insérer un conducteur électrique isolé C dans un des logements 121 de la partie mobile 120 de telle sorte qu'il se trouve placé en regard d'une paire de fentes 111 de connexion d'un organe métallique 110 de la partie fixe 101, orienté perpendiculairement auxdites fentes. La première paroi d'appui 121A correspondante du logement 121 de la partie mobile 120 qui forme un berceau de réception dudit conducteur électrique C s'applique autour de la gaine isolante de celui-ci.In Figure 3 there is shown the self-stripping connector 100 with its movable portion 120 in its intermediate position waiting. In this position, the side wall 120B of the movable portion 120 is offset from that of said base 1. As shown in Figures 4 and 5, in this position of the movable portion 120, the installer can insert an insulated electrical conductor C in one of the housings 121 of the movable portion 120 so that it is placed opposite a pair of slots 111 for connecting a metal member 110 of the fixed portion 101, oriented perpendicularly to said slots. The first corresponding support wall 121A of the housing 121 of the movable part 120 which forms a receiving cradle of said electrical conductor C applies around the insulating sheath thereof.

Puis, comme le montrent les figures 6 à 9, l'installateur fait pivoter la partie mobile 120 sur la partie fixe 101 dans le sens des aiguilles d'une montre pour positionner la partie mobile 120 en position d'introduction. Lors de ce déplacement de la partie mobile 120, la première paroi d'appui 121A du logement 121 correspondant pousse le conducteur électrique isolé C dans les fentes 111 de connexion qui attaque la gaine isolante C2 du conducteur électrique C à deux endroits distincts de façon à établir le contact électrique avec l'âme conductrice C1 dudit conducteur électrique C. Dans cette position d'introduction, la paroi latérale 120B de la partie mobile 120 est alignée avec celle du socle 1.Then, as shown in Figures 6 to 9, the installer rotates the movable portion 120 on the fixed portion 101 in the direction of clockwise to position the movable portion 120 in the insertion position. During this movement of the mobile part 120, the first support wall 121A of the corresponding housing 121 pushes the insulated electrical conductor C into the connection slots 111 which attack the insulating sheath C2 of the electrical conductor C at two points. separate locations so as to establish electrical contact with the conductive core C1 of said electrical conductor C. In this insertion position, the side wall 120B of the movable portion 120 is aligned with that of the base 1.

Comme le montrent les figures 10 à 12, pour connecter un autre conducteur électrique isolé C' à un organe métallique 110 de la partie fixe 101 dudit connecteur 100, l'installateur fait pivoter la partie mobile 120 sur la partie fixe 101 dans le sens inverse des aiguilles d'une montre pour faire passer ladite partie mobile 120 de sa position d'introduction à sa position intermédiaire d'attente (voir figure 10). Durant ce déplacement la seconde paroi d'appui 121'B (destinée à pousser le conducteur C hors de la paire de fente 111 de l'organe métallique) du logement 121 correspondant n'agit pas sur le conducteur C déjà introduit dans la paires de fentes 111 d'un organe métallique 110 car la distance séparant cette seconde paroi d'appui 121'B de la première paroi d'appui 121A est supérieure à la distance parcourue par la partie mobile 120 entre la position d'introduction et la position intermédiaire d'attente. De ce fait, avantageusement, l'installateur place la partie mobile 120 en position intermédiaire d'attente sans que celle-ci ne provoque la déconnexion du conducteur électrique C déjà connecté.As shown in Figures 10 to 12, to connect another insulated electrical conductor C 'to a metal member 110 of the fixed portion 101 of said connector 100, the installer rotates the movable portion 120 on the fixed portion 101 in the opposite direction clockwise to move said movable portion 120 from its introduction position to its intermediate waiting position (see Figure 10). During this movement the second support wall 121'B (intended to push the driver C out of the slot pair 111 of the metal member) of the corresponding housing 121 does not act on the conductor C already introduced in the pair of slots 111 of a metal member 110 because the distance between the second support wall 121'B of the first support wall 121A is greater than the distance traveled by the movable portion 120 between the insertion position and the intermediate position wait. Therefore, advantageously, the installer places the mobile part 120 intermediate waiting position without it causes the disconnection of the already connected electrical conductor C.

Il peut alors insérer le deuxième conducteur électrique isolé C' dans le logement 121 de la partie mobile 120 placée en position intermédiaire d'attente (voir figures 10 et 11) puis faire pivoter cette partie mobile 120 vers la position d'introduction pour forcer ce deuxième conducteur C' dans la paire de fentes 111 correspondantes sans toucher au premier conducteur C déjà connecté (voir figures 12 et 13).It can then insert the second insulated electrical conductor C 'in the housing 121 of the movable part 120 placed in intermediate waiting position (see FIGS. 10 and 11) and then pivot this mobile part 120 towards the insertion position to force this second conductor C 'in the pair of corresponding slots 111 without touching the first conductor C already connected (see Figures 12 and 13).

Sur les figures 14A à 14C on a représenté les étapes de déconnexion des conducteurs électriques isolés C, C'. À partir de la position d'introduction (voir figure 14A) dans laquelle les deux conducteurs électriques sont introduits à force dans les paires de fentes 111 correspondantes, l'installateur fait pivoter la partie mobile 120 sur la partie fixe 101 pour la faire passer tout d'abord en position intermédiaire d'attente (voir figure 14B), puis au-delà de cette position, en position d'extraction (voir figure 14C). La seconde paroi d'appui 121'B dédiée à la déconnexion n'agit pas sur les conducteurs C, C' lors du passage de la partie mobile 120 de sa position d'introduction à sa position d'intermédiaire. Ce n'est que lorsque la partie mobile 120 passe de la position intermédiaire d'attente à la position d'extraction que cette seconde paroi d'appui 121'B prend appui sur la gaine isolante de ces conducteurs C, C' pour les pousser ou les extraire hors des fentes 111 de l'organe métallique (voir figure 14C). Dans cette position d'extraction, la paroi latérale 120B de la partie mobile 120 est encore plus décalée par rapport à celle du socle 1.FIGS. 14A to 14C show the steps of disconnection of the insulated electrical conductors C, C '. From the insertion position (see Figure 14A) in which the two electrical conductors are forced into the corresponding pairs of slots 111, the installer rotates the movable portion 120 on the fixed portion 101 to make it all pass. first intermediate standby position (see Figure 14B), and then beyond this position, in the extraction position (see Figure 14C). The second support wall 121'B dedicated to the disconnection does not act on the conductors C, C 'during the passage of the movable portion 120 from its introduction position to its intermediate position. Only when the movable portion 120 passes from the waiting intermediate position to the extraction position, this second support wall 121'B is supported on the insulating sheath of these conductors C, C 'to push or extract them from the slots 111 of the metal member (see Figure 14C). In this extraction position, the side wall 120B of the movable part 120 is even more displaced compared to that of the base 1.
