A metallic cutting edge transfixes an insulating sheath of the conductor to establish an electrical contact with a conductive core of the conductor. The edge belongs to a metallic stripping unit (160) that is slidably mounted in the body and supported against a wall (115) delimiting the housing, where the wall is elastically deformed under an action of the stripping unit during a rotation of the body.

Description

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

La présente invention concerne de manière générale les bornes de connexion dite auto-dénudantes, qu'il s'agisse de bornes de connexion destinées à intervenir isolément, par exemple pour le raccordement d'un conducteur électrique à un autre, ou qu'il s'agissent de bornes de connexion qui, faisant parties intégrantes du boîtier d'un quelconque appareillage électrique, ou dûment rapportées sur ce boîtier, sont destinées au raccordement, à cet appareillage, des conducteurs électriques nécessaires à sa desserte.The present invention generally relates to the so-called self-stripping connection terminals, whether they are connection terminals intended to act in isolation, for example for connecting one electrical conductor to another, or that it is are connection terminals which, being integral parts of the housing of any electrical equipment, or duly reported on this housing, are intended for connection to this apparatus, the electrical conductors necessary for its service.

Elle concerne plus particulièrement une borne de connexion comprenant un logement de réception d'au moins un conducteur électrique isolé et un organe de connexion électrique comprenant un corps monté à rotation dans ledit logement de réception et un bord coupant métallique qui est adapté à transpercer la gaine isolante du conducteur électrique isolé introduit dans ledit logement de réception pour établir un contact électrique avec son âme conductrice.It relates more particularly to a connection terminal comprising a housing for receiving at least one insulated electrical conductor and an electrical connection member comprising a body rotatably mounted in said receiving housing and a metal cutting edge which is adapted to pierce the sheath. insulating electrical insulated conductor introduced into said receiving housing for making electrical contact with its conductive core.

Elle concerne également un appareillage électrique intégrant une telle borne de connexion auto-dénudante.It also relates to electrical equipment incorporating such a self-stripping connection terminal.

ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND

Les moyens pour dénuder un conducteur électrique dans les bornes de connexion auto-dénudantes déjà connues, sont classiquement des moyens d'arrachement, de perçage ou de découpage de la gaine isolante du conducteur électrique, suivant une direction sensiblement perpendiculaire ou parallèle à l'axe dudit conducteur.The means for stripping an electrical conductor in the self-stripping connection terminals already known, are conventionally means for tearing, drilling or cutting the insulating sheath of the electrical conductor, in a direction substantially perpendicular or parallel to the axis said driver.

Il peut s'agir d'une fente dont le fond forme un logement de l'âme conductrice du conducteur et pourvue de lèvres coupantes s'étendant perpendiculairement à l'axe dudit conducteur. Cette fente est solidaire d'un couvercle apte à venir fermer un logement de réception. Le conducteur électrique est logé en partie dans ledit logement de réception, puis le couvercle est rabattu sur celui-ci de sorte que la fente enfourche ledit conducteur électrique. Le conducteur électrique s'introduit alors dans la fente, suivant une direction d'introduction parallèle auxdites lèvres coupantes, et celles-ci coupent et déplacent localement la gaine isolante dudit conducteur selon une direction perpendiculaire à l'axe de ce dernier, de sorte qu'une partie de son âme conductrice se loge dans le fond de ladite fente et réalise le contact électrique avec la borne.It may be a slot whose bottom forms a housing of the conductive core of the conductor and provided with cutting lips extending perpendicularly to the axis of said conductor. This slot is secured to a cover adapted to close a receiving housing. The electrical conductor is housed partially in said receiving housing, then the cover is folded down thereon so that the slot straddles said electrical conductor. The electrical conductor then enters the slot, in a direction of introduction parallel to said cutting lips, and these cut and move locally the insulating sheath of said conductor in a direction perpendicular to the axis of the latter, so that a portion of its conductive core is housed in the bottom of said slot and makes electrical contact with the terminal.

Il peut aussi s'agir d'une pointe métallique qui vient percer la gaine isolante du conducteur électrique placé dans un logement de réception, le perçage s'effectuant suivant une direction perpendiculaire à l'axe dudit conducteur, de façon à venir au contact de l'âme conductrice dudit conducteur pour réaliser le raccordement électrique.It may also be a metal tip which pierces the insulating sheath of the electrical conductor placed in a receiving housing, the drilling being performed in a direction perpendicular to the axis of said conductor, so as to come into contact with the conductive core of said conductor for making the electrical connection.

L'inconvénient principal de telles bornes de connexion auto-dénudantes est que leurs moyens de dénudage sont adaptés à dénuder des conducteurs électriques isolés ayant un diamètre donné.The main disadvantage of such self-stripping connection terminals is that their stripping means are suitable for stripping insulated electrical conductors having a given diameter.

On connaît par ailleurs du document FR 2 871 952 appartenant aux demanderesses, une borne de connexion du type de celle décrite dans l'introduction, dans laquelle le logement de réception est défini à l'intérieur d'une cage métallique parallélépipédique, ouverte sur deux faces en regard, pourvue de deux parois en vis-à-vis percées d'orifices pour le montage à rotation d'un organe de connexion à l'intérieur de ladite cage.It is also known from the document FR 2,871,952 belonging to the applicants, a connection terminal of the type described in the introduction, in which the receiving housing is defined inside a parallelepipedal metal cage, open on two facing faces, provided with two screwed walls with holes drilled for the rotational mounting of a connection member inside said cage.

Selon ce document, l'organe de connexion comprend deux bords coupants métalliques sensiblement parallèles à son axe de rotation, positionnés à l'opposé l'un de l'autre par rapport à l'axe de rotation. Ces deux bords coupants sont chacun adaptés à peler des gaines isolantes de deux conducteurs électriques introduits par des entrées distinctes dans ledit logement de réception, d'un côté et de l'autre de l'organe de connexion.According to this document, the connection member comprises two metal cutting edges substantially parallel to its axis of rotation, positioned opposite one another with respect to the axis of rotation. These two cutting edges are each adapted to peel insulating sheaths of two electrical conductors introduced by separate inputs into said receiving housing, on one side and the other of the connection member.

Le document DE 1 982 563 C1 , qui est considéré comme l'état de la technique le plus proche, décrit une borne de connexion auto-dénudante selon le préambule de la revendication 1.The document DE 1 982 563 C1 , which is considered to be the closest state of the art, describes a self-stripping connection terminal according to the preamble of claim 1.

On comprend que selon la forme de l'organe de connexion et selon sa position centrée ou décentrée dans le logement de réception, la distance entre les parois de la cage et chacun des bords coupants de l'organe de connexion est variable. Les deux entrées distinctes sont donc adaptées à accueillir des conducteurs électriques isolés présentant des sections différentes. Une même entrée ne peut en revanche pas accueillir des conducteurs électriques présentant des sections différentes. Le choix de l'entrée d'introduction des conducteurs électriques doit donc être réalisé avec attention par une personne compétente.It is understood that depending on the shape of the connection member and in its position centered or off-center in the receiving housing, the distance between the walls of the cage and each of the cutting edges of the connecting member is variable. The two separate inputs are adapted to accommodate insulated electrical conductors with different sections. The same input can not however accommodate electrical conductors with different sections. The choice of the entry input of the electrical conductors must be carefully made by a competent person.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Afin de remédier à l'inconvénient précité de l'état de la technique, la présente invention propose une borne de connexion qui s'adapte automatiquement au diamètre du conducteur électrique isolé introduit dans son logement de réception.In order to overcome the aforementioned drawback of the state of the art, the present invention proposes a connection terminal which automatically adapts to the diameter of the isolated electrical conductor introduced into its receiving housing.

Plus particulièrement, on propose selon l'invention une borne de connexion telle que définie dans la revendication 1.More particularly, there is provided according to the invention a connection terminal as defined in claim 1.

Ainsi, lorsqu'un conducteur électrique isolé est engagé dans le logement de réception et que le corps pivote autour de son axe de rotation, le bord coupant de l'organe de dénudage perce la gaine isolante souple du conducteur et vient au contact de son âme conductrice métallique. Ce contact engendre un effort qui a tendance à pousser l'organe de dénudage hors dudit corps, en direction de la paroi élastiquement déformable. L'organe de dénudage étant déjà au contact de cette paroi élastiquement déformable, cette dernière crée une contre-poussée qui maintient, pendant toute la rotation du corps, l'organe de dénudage au contact de l'âme conductrice du conducteur électrique. L'organe de dénudage glisse donc le long de l'âme conductrice du conducteur électrique tout en continuant de trancher sa gaine isolante souple.Thus, when an insulated electrical conductor is engaged in the receiving housing and the body pivots about its axis of rotation, the cutting edge of the stripping member pierces the flexible insulating sheath of the conductor and comes into contact with his soul. metallic conductor. This contact generates a force that tends to push the stripping member out of said body, towards the elastically deformable wall. The stripping member already being in contact with this elastically deformable wall, the latter creates a counter-thrust which maintains, throughout the rotation of the body, the stripping member in contact with the conductive core of the electrical conductor. The stripping member thus slides along the conductive core of the electrical conductor while continuing to slice its flexible insulating sheath.

De ce fait on garantit un bon dénudage et une bonne connexion électrique du conducteur électrique isolé à la borne, pour une gamme de différentes sections de conducteurs électriques.As a result, good stripping and good electrical connection of the insulated electrical conductor to the terminal is guaranteed for a range of different electrical conductor sections.

Une seule entrée de conducteur électrique autorise le branchement de conducteurs différents, si bien qu'une personne ne possédant pas de compétences particulières en électricité peut aisément brancher des conducteurs électriques à cette borne de connexion.A single electrical conductor input allows the connection of different conductors, so that a person with no particular electrical skills can easily connect electrical conductors to this connection terminal.

D'autres caractéristiques avantageuses et non limitatives de la borne de connexion selon l'invention sont les suivantes :

  • ledit corps est monté à rotation autour d'un axe de rotation perpendiculaire, d'une part, au plan dans lequel s'étend le bord coupant de l'organe de dénudage, et, d'autre part, à l'axe de glissement de l'organe de dénudage, cet axe de glissement étant contenu dans ledit plan du bord coupant ;

Sur la figure 1, on a représenté un appareillage électrique 1, ici une prise de courant, comprenant un socle ou boîtier 10 isolant, fermé à l'avant par un enjoliveur 20.On the figure 1 , there is shown an electrical apparatus 1, here a socket, comprising a base or insulating housing 10, closed at the front by a hubcap 20.

Le boîtier 10 est ici de forme parallélépipédique carrée avec une paroi de fond bordée par quatre parois latérales délimitant un logement intérieur 11. Les parois latérales portent sur leur face externe, à proximité de l'ouverture avant du boîtier, un trottoir 15 périphérique.The housing 10 is here of square parallelepipedal shape with a bottom wall bordered by four side walls delimiting an inner housing 11. The side walls carry on their outer face, near the front opening of the housing, a peripheral sidewalk 15.

Comme le montrent les figures 1 et 2, l'enjoliveur 20 se présente sous la forme d'une plaque bordée par un bord tombant 21. La partie centrale de l'enjoliveur 20 présente en renfoncement un puits 22 d'insertion d'une fiche. Ce puits 22 est délimité par une paroi latérale cylindrique et par une paroi de fond plane percée de trois ouvertures 23, 24, 25 de passage de broches de connexion.As shown by figures 1 and 2 , the hubcap 20 is in the form of a plate bordered by a falling edge 21. The central portion of the hubcap 20 has a recess 22 for inserting a plug. This well 22 is delimited by a cylindrical side wall and a flat bottom wall pierced with three openings 23, 24, 25 of connection pin passage.

Deux de ces ouvertures 23, 24 sont adaptées à permettre le passage de deux broches d'une fiche électrique (non représentée) insérée dans le puits 22. La troisième de ces ouvertures 25 est adaptée à être traversée par une broche de terre 320 appartenant à l'appareillage électrique 1.Two of these openings 23, 24 are adapted to allow the passage of two pins of an electrical plug (not shown) inserted in the well 22. The third of these openings 25 is adapted to be traversed by a ground pin 320 belonging to electrical equipment 1.

Comme le montre plus particulièrement la figure 1, la face externe de la paroi latérale cylindrique du puits 22 de l'enjoliveur 20 présente des dents 26 pour l'encliquetage de l'enjoliveur 20 sur le boîtier 10.As shown more particularly in figure 1 , the outer face of the cylindrical side wall of the well 22 of the hubcap 20 has teeth 26 for snapping the hubcap 20 onto the casing 10.

Lorsque l'enjoliveur 20 est monté sur le boîtier 10, sa plaque ferme l'ouverture avant de celui-ci, le bord tombant 21 s'appliquant contre le trottoir 15. Le puits 22 de l'enjoliveur 20 est inséré dans le logement intérieur 11 du boîtier 10 de manière que les dents 26 portées par la paroi cylindrique qui le délimite s'accroche sur une partie intérieure 18 du boîtier 10.When the hubcap 20 is mounted on the housing 10, its plate closes the front opening thereof, the falling edge 21 applying against the sidewalk 15. The well 22 of the hubcap 20 is inserted into the inner housing 11 of the housing 10 so that the teeth 26 carried by the cylindrical wall which delimits it clings to an inner portion 18 of the housing 10.

Comme le montrent les figures 4 et 6, le boîtier 10 comporte dans son logement intérieur 11 des cloisons 14 qui s'étendent à partir de sa paroi de fond, orthogonalement à elle, et qui délimitent trois compartiments ouverts vers l'avant du boîtier. Ces compartiments constituent des logements d'intégration 12 destinés à recevoir chacun une borne de connexion 100, 200, 300. Ils sont disposés les uns à côtés des autres et sont contigus à une même paroi latérale 17 du boîtier, ici appelée paroi latérale d'entrée.As shown by figures 4 and 6 , the housing 10 has in its inner housing 11 partitions 14 which extend from its bottom wall, orthogonally to it, and which define three compartments open towards the front of the housing. These compartments constitute integration housings 12 intended to each receive a connection terminal 100, 200, 300. They are arranged next to each other and are contiguous to the same side wall 17 of the housing, here called side wall of Entrance.

Ainsi, le boîtier 10 loge intérieurement trois bornes de connexion dont une borne de phase 100, une borne de neutre 200, et une borne de terre 300.Thus, the housing 10 internally houses three connection terminals including a phase terminal 100, a neutral terminal 200, and a ground terminal 300.

La paroi latérale d'entrée 17 présente des ouvertures 13 disposées à la hauteur des logements d'intégration 12, sur l'arête du boîtier 10 séparant sa paroi latérale d'entrée et sa paroi de fond. Chacune de ces ouvertures 13 forme un passage pour l'introduction d'un conducteur électrique isolé 400 selon une direction Y dans une des bornes de connexion 100, 200, 300 logée à l'intérieur d'un des logements d'intégration 12 du boîtier 10 (figures 2 et 6).The inlet side wall 17 has openings 13 disposed at the height of the integration housing 12, on the edge of the housing 10 separating its inlet side wall and its bottom wall. Each of these openings 13 forms a passage for the introduction of an insulated electrical conductor 400 in a direction Y into one of the connection terminals 100, 200, 300 housed inside one of the integration housing 12 of the housing 10 ( figures 2 and 6 ).

Plus particulièrement, comme le montrent les figures 1 et 4, les bornes de phase et de neutre 100, 200 comprennent chacune une alvéole de réception d'une broche d'une fiche électrique. Chaque alvéole est définie à l'intérieur d'une pince 120, 220 destinée à enserrer une broche de la fiche qui traverse une des ouvertures 23, 24 de la paroi de fond du puits 22 de l'enjoliveur 20. À cet effet, chacune desdites alvéoles est positionnée dans le boîtier 10 au droit d'une des ouvertures 23, 24 prévue dans le fond du puits 22.In particular, as shown by the figures 1 and 4 the phase and neutral terminals 100, 200 each comprise a socket for receiving a pin from an electric plug. Each cell is defined inside a clamp 120, 220 for gripping a pin of the plug which passes through one of the openings 23, 24 of the bottom wall of the well 22 of the hubcap 20. For this purpose, each said cells are positioned in the housing 10 in line with one of the openings 23, 24 provided in the bottom of the well 22.

La borne de terre 300 comprend une broche 320 qui traverse la troisième ouverture 25 pour émerger dans le puits 22.The ground terminal 300 includes a pin 320 which passes through the third opening 25 to emerge in the well 22.

De manière connue en soi, comme le montrent les figures 1 et 2, la prise de courant 1 est ici accessoirisée d'un obturateur 30 dont les volets 31 s'interposent entre les ouvertures 23, 24 du fond du puits 22 de l'enjoliveur 20 et les alvéoles des bornes de phase et de neutre 100, 200 de l'appareillage électrique 1. L'obturateur 30 est monté à rotation dans le boîtier 10 pour que les deux volets 31 s'effacent lorsque les deux broches de la fiche électrique appuient simultanément sur eux.In a manner known per se, as shown by figures 1 and 2 , the socket 1 is here accessorized with a shutter 30 whose flaps 31 are interposed between the openings 23, 24 of the bottom of the well 22 of the hubcap 20 and the cells of the phase and neutral terminals 100, 200 of the electrical equipment 1. The shutter 30 is rotatably mounted in the housing 10 so that the two flaps 31 are erased when the two pins of the electrical plug simultaneously press on them.

Comme le montrent particulièrement les figures 1, 4 et 6, chaque borne de connexion 100, 200, 300 est une borne de connexion auto-dénudante qui comprend un logement de réception 101, 201, 301 d'un conducteur électrique isolé 400, ainsi qu'un organe de connexion 150, 250, 350 électrique comprenant un corps 151, 251, 351 monté à rotation dans ledit logement de réception et au moins un bord coupant 161A, 361A métallique qui est adapté à transpercer la gaine isolante 401 du conducteur électrique isolé 400 introduit dans ledit logement de réception 101, 201, 301 pour établir un contact électrique avec son âme conductrice 402.As is particularly the case figures 1 , 4 and 6 each connection terminal 100, 200, 300 is a self-stripping connection terminal which comprises a receiving housing 101, 201, 301 of an insulated electrical conductor 400, as well as an electrical connection member 150, 250, 350 comprising a body 151, 251, 351 rotatably mounted in said receiving housing and at least one metal cutting edge 161A, 361A which is adapted to pierce the insulating sheath 401 of the insulated electrical conductor 400 introduced into said receiving housing 101, 201, 301 for establishing electrical contact with its conductive core 402.

Comme le montrent plus particulièrement les figures 1 et 4 à 7, chaque borne de connexion comprend une pièce monobloc 110, 210, 310 globalement en forme de U, obtenue par découpage, formage et/ou pliage d'une lamelle métallique. Les parois de cette pièce monobloc 110, 210, 310 délimitent le logement de réception 101, 201, 301 de chaque borne de connexion 100, 200, 300.As shown more particularly by figures 1 and 4 to 7 each connection terminal comprises a monobloc piece 110, 210, 310 generally U-shaped, obtained by cutting, forming and / or folding a metal strip. The walls of this monobloc piece 110, 210, 310 delimit the receiving housing 101, 201, 301 of each connection terminal 100, 200, 300.

L'une des branches parallèles de la pièce monobloc 110, 210, 310 en U est une paroi en forme de gouttière 112, 212, 312 dont la concavité est orientée vers ledit logement de réception 101, 201, 301 de la borne de connexion 100, 200, 300. Cette paroi en forme de gouttière 112, 212, 312 est destinée à recevoir et à guider un conducteur électrique isolé 400 introduit dans ledit logement de réception.One of the parallel branches of the one-piece piece 110, 210, 310 in U is a gutter-shaped wall 112, 212, 312 whose concavity is oriented towards said receiving housing 101, 201, 301 of the connection terminal 100 , 200, 300. This gutter-shaped wall 112, 212, 312 is intended to receive and guide an insulated electrical conductor 400 introduced into said receiving housing.

L'autre des branches parallèles de la pièce monobloc en U est une paroi 115, 215, 315 conformée pour se déformer élastiquement. Cette paroi 115, 215, 315 présente ici la forme d'une épingle à cheveux avec un coude 115A, 215A, 315A formant une charnière de pivotant qui se raccorde, d'un côté, à une portion plane 115C, 215C, 315C rattachée à la base 111, 211, 311 de la pièce monobloc en U, et, de l'autre côté, à une branche libre 115B, 215B, 315B formant une rampe qui fait face à ladite paroi en forme de gouttière 112, 212, 312 (voir figures 1, 5 et 7).The other of the parallel branches of the U-shaped piece is a wall 115, 215, 315 shaped to deform elastically. This wall 115, 215, 315 here has the shape of a hairpin with a bend 115A, 215A, 315A forming a pivot hinge which is connected, on one side, to a portion 115C, 215C, 315C attached to the base 111, 211, 311 of the U-shaped piece, and, on the other side, to a free leg 115B, 215B, 315B forming a ramp which faces said shaped wall gutter 112, 212, 312 (see figures 1 , 5 and 7 ).

Ainsi, lorsqu'un effort de pression est exercé sur ladite branche libre 115B, 215B, 315B, celle-ci se rapproche de ladite portion plane 115C, 215C, 315C par pliage élastique dudit coude 115A, 215A, 315A.Thus, when a pressure force is exerted on said free leg 115B, 215B, 315B, it approaches said planar portion 115C, 215C, 315C by elastic folding of said bend 115A, 215A, 315A.

Selon l'exemple représenté, chaque borne de connexion 100, 200, 300 est une borne double adaptée à connecter deux conducteurs électriques isolés 400, un conducteur d'alimentation provenant du réseau et un conducteur de repiquage.According to the example shown, each connection terminal 100, 200, 300 is a dual terminal adapted to connect two insulated electrical conductors 400, a supply conductor coming from the network and a transient conductor.

Les parois de la pièce monobloc 110, 210, 310 en forme de U de chaque borne de connexion 100, 200, 300 délimitent un double logement de réception 101, 201, 301. Pour cela, ladite pièce en U comporte, dans l'une de ses branches parallèles, côte à côte, deux parois identiques en forme de gouttière 112, 212, 312 pour la réception de deux conducteurs électriques isolés, et, dans l'autre de ses branches parallèles, côte à côte, deux parois 115, 215, 315 identiques en forme d'épingle à cheveux. Les parois en forme de gouttière 112, 212, 312 et les parois 115, 215, 315 en forme d'épingle à cheveux sont respectivement séparées par une fente et se rattachent à une même base 111, 211, 311 de la pièce monobloc 110, 210, 310 en U (voir figure 1).The walls of the one-piece piece 110, 210, 310 in the shape of a U of each connection terminal 100, 200, 300 delimit a double receiving housing 101, 201, 301. For this, said U-shaped part comprises, in one of its parallel branches, side by side, two identical gutter-shaped walls 112, 212, 312 for the reception of two insulated electrical conductors, and, in the other of its parallel branches, side by side, two walls 115, 215 , 315 identical hairpin-shaped. The gutter-shaped walls 112, 212, 312 and the hairpin-shaped walls 115, 215, 315 are respectively separated by a slot and are connected to the same base 111, 211, 311 of the one-piece piece 110, 210, 310 in U (see figure 1 ).

La base 111, 211 de la pièce monobloc 110, 210 en U de chacune des bornes de phase 100 et de neutre 200 est paroi de connexion qui est rattachée par une paroi en L à ladite pince 120, 220 qui délimite l'alvéole de réception de la borne. Ici la paroi en L, la pièce en U et la pince de chaque borne forment une seule partie obtenue par découpage, formage et/ou pliage d'une lamelle métallique.The base 111, 211 of the one-piece piece 110, 210 in U of each of the phase and neutral terminals 200 and 100 is a connecting wall which is connected by an L-shaped wall to said clamp 120, 220 which delimits the receiving cell. from the terminal. Here the L-shaped wall, the U-shaped piece and the clamp of each terminal form a single part obtained by cutting, forming and / or folding a metal strip.

Sur la base 311 de la pièce monobloc 310 en U de la borne de terre 300 est rapportée (par soudage) une languette 320A de support de la broche de terre 320.On the base 311 of the monobloc piece 310 in U of the earth terminal 300 is reported (by welding) a tongue 320A for supporting the earth pin 320.

Comme le montrent plus particulièrement les figures 4 à 7, chaque pièce monobloc 110, 310 en U de chaque borne de connexion 100, 300 est insérée dans un logement d'intégration 12 du boîtier 10 de manière qu'elle s'ouvre vers les ouvertures 13 correspondantes de la paroi latérale d'entrée 17 du boîtier 10. En particulier, le double logement de réception 101, 301 de la pièce monobloc 110, 310 en U se positionne en regard de deux ouvertures 13 distinctes, placées côte à côte, de la paroi latérale d'entrée 17 du boîtier 10. Chaque paroi en forme de gouttière 112, 312 de ladite pièce monobloc 110, 310 se positionne contre la paroi de fond du boîtier 10 en regard d'une des ouvertures 13 de ladite paroi latérale d'entrée 17 et la base 111, 311 de ladite pièce monobloc 110, 310 se cale contre une cloison intérieure 14 du boîtier 10.As shown more particularly by Figures 4 to 7 each monoblock piece 110, 310 in U of each connection terminal 100, 300 is inserted into an integration housing 12 of the housing 10 so that it opens towards the corresponding openings 13 of the inlet side wall 17 10. In particular, the double receiving housing 101, 301 of the monobloc piece 110, 310 U is positioned opposite two separate openings 13, placed side by side, the inlet side wall 17 of the housing 10. Each shaped wall gutter 112, 312 of said monobloc piece 110, 310 is positioned against the bottom wall of the housing 10 opposite one of the openings 13 of said inlet side wall 17 and the base 111, 311 of said monobloc piece 110, 310 is wedged against an inner partition 14 of the housing 10.

Comme le montre plus particulièrement la figure 1, le corps 151, 251, 351 de l'organe de connexion 150, 250, 350 de chaque borne de connexion 100, 200, 300 est un corps cylindrique globalement de révolution autour d'un axe V.As shown more particularly in figure 1 , the body 151, 251, 351 of the connection member 150, 250, 350 of each connection terminal 100, 200, 300 is a generally cylindrical body of revolution about a V axis.

Il porte à chaque extrémité un tourillon 154, 354 aligné sur l'axe V. Les tourillons 154, 354 sont destinés à être monté dans des paliers intérieurs du boîtier 10 pour le montage à rotation autour de l'axe V dudit corps 151, 351 dans le logement de réception de la borne de connexion 100, 300. L'axe V de rotation du corps 151, 251, 351 de chaque organe de connexion 150, 250, 350 est orthogonal à la direction Y d'introduction du conducteur électrique isolé 400 dans le logement de réception 101, 201, 301 de la borne de connexion 100, 200, 300.It carries at each end a pin 154, 354 aligned with the axis V. The pins 154, 354 are intended to be mounted in inner bearings of the casing 10 for rotationally mounting about the axis V of said body 151, 351 in the receiving housing of the connection terminal 100, 300. The axis V of rotation of the body 151, 251, 351 of each connection member 150, 250, 350 is orthogonal to the direction Y of introduction of the isolated electrical conductor 400 in the receiving housing 101, 201, 301 of the connection terminal 100, 200, 300.

Avantageusement comme le montrent les figures, le corps 151, 351 de chaque organe de connexion 150, 350 est percé de part en part de deux fentes 152, 352 parallèles de section rectangulaire, s'étendant selon des axes de glissement W, perpendiculaires à l'axe V de rotation du corps 151, 351. Chaque fente 152, 352 comporte sur ses deux parois latérales d'extrémité deux décrochements 153, 353 en regard l'un de l'autre (voir figures 5 et 7).Advantageously, as shown in the figures, the body 151, 351 of each connecting member 150, 350 is pierced right through two parallel slots 152, 352 of rectangular section, extending along sliding axes W, perpendicular to the V axis of rotation of the body 151, 351. Each slot 152, 352 has on its two end side walls two recesses 153, 353 facing each other (see Figures 5 and 7 ).

Chaque fente accueille un organe de dénudage 160, 260, 360 en forme de couteau métallique dont une extrémité est pourvue du bord coupant 161A, 361A adapté à transpercer la gaine isolante 401 d'un conducteur électrique isolé 400 engagé dans le logement de réception de la borne correspondante.Each slot accommodates a stripping member 160, 260, 360 in the form of a metal knife whose end is provided with the cutting edge 161A, 361A adapted to pierce the insulating sheath 401 of an insulated electrical conductor 400 engaged in the receiving housing of the corresponding terminal.

Comme le montrent plus particulièrement les figures 5 et 7, l'axe V de rotation de chaque corps 151, 351 est perpendiculaire, d'une part, au plan dans lequel s'étend le bord coupant 161A, 361A de chaque organe de dénudage 160, 360 qu'il porte et, d'autre part, à l'axe de glissement W de chaque organe de dénudage 160, 360, cet axe de glissement W étant contenu dans ledit plan du bord coupant 161A, 361A.As shown more particularly by Figures 5 and 7 the axis V of rotation of each body 151, 351 is perpendicular, on the one hand, to the plane in which extends the cutting edge 161A, 361A of each stripping member 160, 360 which it carries and, on the other hand, to the sliding axis W of each stripping member 160, 360, this sliding axis W being contained in said plane of the cutting edge 161A, 361A.

La longueur de chaque organe de dénudage 160, 260, 360 est supérieure au diamètre du corps 151, 251, 351. Ainsi, lorsque l'organe de dénudage 160, 260, 360 est engagé dans la fente correspondante du corps 151, 251, 351, ses deux extrémités émergent à l'extérieur de celle-ci. L'épaisseur et la largeur de chaque organe de dénudage 160, 260, 360 sont ajustées à l'épaisseur et à la largeur de la fente qui l'accueille de sorte qu'il peut glisser librement dans ladite fente selon l'axe de glissement W. Chaque organe de dénudage 160, 360 comporte sur ses deux bords longitudinaux opposés deux épaulements 163, 363 par lesquels il vient en butée contre les décrochements 153, 353 de la fente 152, 352 pour être maintenu dans celle-ci (voir figures 5 et 7).The length of each stripping member 160, 260, 360 is greater than the diameter of the body 151, 251, 351. Thus, when the stripping member 160, 260, 360 is engaged in the corresponding slot of the body 151, 251, 351 , both ends emerge on the outside of it. The thickness and the width of each stripping member 160, 260, 360 are adjusted to the thickness and the width of the slot which receives it so that it can slide freely in said slot along the sliding axis. W. Each stripping member 160, 360 has on its two opposite longitudinal edges two shoulders 163, 363 by which it abuts against the recesses 153, 353 of the slot 152, 352 to be held in it (see Figures 5 and 7 ).

Lorsque le corps 151, 251, 351 de l'organe de connexion 150, 250, 350 est monté dans le double logement de réception de la borne de connexion correspondante, sa surface cylindrique vient en appui glissant contre la branche libre 115B, 215B, 315B formant une rampe d'une paroi 115, 215, 315 déformable élastiquement de la pièce monobloc 110, 210, 310 en U.When the body 151, 251, 351 of the connection member 150, 250, 350 is mounted in the double receiving housing of the corresponding connection terminal, its cylindrical surface comes into sliding abutment against the free branch 115B, 215B, 315B forming a ramp of a wall 115, 215, 315 elastically deformable of the one-piece piece 110, 210, 310 in U.

Chaque organe de dénudage 160, 360, engagé dans chaque fente du corps de l'organe de connexion, vient également, par son extrémité opposée 162, 362 à celle portant le bord coupant 161A, 361A, en appui glissant contre la branche libre 115B, 315B formant une rampe de chaque paroi 115, 315 déformable élastiquement de la pièce monobloc en U (voir figures 4 à 7).Each stripping member 160, 360, engaged in each slot of the body of the connection member, also comes, by its opposite end 162, 362 to the one carrying the cutting edge 161A, 361A, sliding against the free leg 115B, 315B forming a ramp of each wall 115, 315 elastically deformable of the U-shaped piece (see Figures 4 to 7 ).

La branche libre 115B, 315B formant une rampe de chaque paroi 115, 315 déformable présente une forme arrondie concave contre laquelle vient en appui glissant la surface cylindrique du corps 151, 351 de l'organe de connexion 150, 350 ainsi qu'un bord de glissement 162, 362 de forme complémentaire de l'organe de dénudage 160, 360 correspondant. La longueur de ladite branche libre 115B, 315B formant une rampe est telle que l'organe de dénudage 160, 360 correspondant reste constamment au contact de ladite rampe 115B, 315B quelle que soit la position angulaire du corps 151, 351 de l'organe de connexion 150, 350 dans le double logement de réception de la borne de connexion 100, 300 correspondante.The free branch 115B, 315B forming a ramp of each wall 115, 315 which is deformable has a concave rounded shape against which the cylindrical surface of the body 151, 351 of the connecting member 150, 350 and sliding edge comes into sliding abutment. slip 162, 362 complementary shape of the stripping member 160, 360 corresponding. The length of said free leg 115B, 315B forming a ramp is such that the stripping member 160, 360 corresponding remains constantly in contact with said ramp 115B, 315B regardless of the angular position of the body 151, 351 of the body of connection 150, 350 in the double receiving housing of the connection terminal 100, 300 corresponding.

Ainsi, avantageusement, chaque organe de dénudage 160, 360 est bloqué, dans un sens de translation, par les décrochements 153, 353 de la fente dans laquelle il est logé, et, dans l'autre sens de translation, par ladite paroi 115, 315 déformable élastiquement contre laquelle il est en appui.Thus, advantageously, each stripping member 160, 360 is blocked, in a direction of translation, by the recesses 153, 353 of the slot in which it is housed, and, in the other direction of translation, by said wall 115, 315 elastically deformable against which it is supported.

Le corps 151, 251, 351 de chaque organe de connexion 150, 250, 350 est apte à être pivoté autour de son axe V au moyen d'un levier d'actionnement 156, 256, 356 entre une position de déconnexion (voir figures 4 et 5) et une position de connexion (voir figures 6 et 7).The body 151, 251, 351 of each connection member 150, 250, 350 is able to be pivoted about its axis V by means of an actuating lever 156, 256, 356 between a disconnection position (see FIG. figures 4 and 5 ) and a connection position (see Figures 6 and 7 ).

Ce levier d'actionnement 156, 256, 356 présente une forme allongée d'axe Z orthogonal à l'axe V de rotation du corps 151, 251, 351. Une des extrémités du levier d'actionnement 156, 256, 356 se rattache à la surface cylindrique du corps 151, 251, 351. L'autre extrémité de ce levier d'actionnement 156, 256, 356 est libre et est pourvue d'une languette 157, 257, 357 accessible à l'usager.This actuating lever 156, 256, 356 has an elongated Z-axis shape orthogonal to the axis V of rotation of the body 151, 251, 351. One end of the actuating lever 156, 256, 356 is attached to the cylindrical surface of the body 151, 251, 351. The other end of the actuating lever 156, 256, 356 is free and is provided with a tab 157, 257, 357 accessible to the user.

Le corps 151, 251, 351 et le levier d'actionnement 156, 256, 356 forment ici une seule pièce réalisée par moulage d'une matière plastique isolante.The body 151, 251, 351 and the actuating lever 156, 256, 356 form here a single piece made by molding an insulating plastic material.

Lorsque le corps 151, 251, 351 de chaque organe de connexion 150, 250, 350 est placé dans le double logement de réception de la borne de connexion correspondante, le levier d'actionnement 156, 256, 356 émerge à l'extérieur du boîtier au travers d'une ouverture allongée pratiquée dans la paroi de fond dudit boîtier.When the body 151, 251, 351 of each connection member 150, 250, 350 is placed in the double receiving housing of the corresponding connection terminal, the operating lever 156, 256, 356 emerges outside the housing through an elongate opening in the bottom wall of said housing.

Chaque levier d'actionnement 156, 256, 356 est adapté à pivoter d'un angle A1 compris entre 45 et 90 degrés, préférentiellement égal à 65 degrés.Each actuating lever 156, 256, 356 is adapted to pivot at an angle A1 of between 45 and 90 degrees, preferably equal to 65 degrees.

Avantageusement, l'arrière dudit boîtier 10 de l'appareillage électrique est aménagé pour recevoir les languettes 157, 257, 357 des trois leviers d'actionnement 156, 256, 356 des organes de connexion 150, 250, 350 de telle manière qu'elles soient accessibles par l'extérieur du boîtier 10 et qu'en position de connexion, elles soient positionnées en retrait de la face arrière dudit boîtier 10 (voir figure 6).Advantageously, the rear of said housing 10 of the electrical equipment is arranged to receive the tabs 157, 257, 357 of the three actuating levers 156, 256, 356 of the connecting members 150, 250, 350 so that they are accessible from the outside of the housing 10 and in the connection position, they are positioned back from the rear face of said housing 10 (see figure 6 ).

Plus particulièrement, ici, la face arrière du boîtier 10 comporte trois renfoncements 16 qui s'étendent en parallèle sur environ la moitié de largeur du boîtier 10. Ces renfoncements 16 débouchent sur un bord du boîtier à l'opposé de la paroi latérale d'entrée 17 (voir figures 1, 4 et 6). Chacun des renfoncements 16 est destiné à accueillir une languette 157, 257, 357 d'un levier d'actionnement 156, 256, 356 en position de connexion.More particularly, here, the rear face of the housing 10 has three recesses 16 which extend in parallel over approximately half the width of the housing 10. These recesses 16 open on an edge of the housing opposite the side wall of the housing. entry 17 (see figures 1 , 4 and 6 ). Each of the recesses 16 is intended to accommodate a tongue 157, 257, 357 of an actuating lever 156, 256, 356 in the connection position.

Les figures 4 et 5 montrent plus particulièrement la borne de phase 100 en position de déconnexion. Dans cette position, le levier d'actionnement 156, en saillie de la face arrière du boîtier, forme un angle A1 d'environ 65 degrés avec l'axe du renfoncement 16 du boîtier 10. Il positionne le corps 151 de manière à basculer le bord coupant 161A chaque organe de dénudage 160 hors du passage d'introduction d'un conducteur électrique isolé dans ledit logement de réception 101 de la borne de phase 100.The figures 4 and 5 show more particularly the phase terminal 100 in the disconnection position. In this position, the actuating lever 156, projecting from the rear face of the housing, forms an angle A1 of about 65 degrees with the axis of the recess 16 of the housing 10. It positions the body 151 so as to tilt the cutting edge 161A each stripping member 160 out of the insertion passage of an insulated electrical conductor in said receiving housing 101 of the terminal of phase 100.

On peut alors aisément introduire ou extraire un conducteur électrique isolé dans le logement de réception de la borne de phase 100 via l'ouverture 13 correspondante du boîtier 10.It is then easy to introduce or extract an insulated electrical conductor into the receiving housing of the phase terminal 100 via the corresponding opening 13 of the housing 10.

Le levier d'actionnement 156 est stable dans cette position de déconnexion car son dos prend appui contre le bord libre d'une paroi interne 19 du boîtier 10.The operating lever 156 is stable in this disconnection position because its back bears against the free edge of an inner wall 19 of the housing 10.

Les figures 6 et 7 montrent plus particulièrement la borne de terre 300 en position de connexion.The Figures 6 and 7 show more particularly the earth terminal 300 in the connection position.

Pour passer de la position de déconnexion (représentée sur la figure 4) à la position de connexion (représentée sur la figure 6) l'utilisateur fait simplement pivoter le levier d'actionnement 356 de l'angle A1 afin de le loger dans le renfoncement 16 correspondant du boîtier 10.To switch from the disconnect position (shown on the figure 4 ) at the connection position (shown on the figure 6 ) the user simply pivots the operating lever 356 of the angle A1 in order to accommodate it in the recess 16 corresponding to the housing 10.

Ce mouvement de pivotement du levier d'actionnement 356 entraîne la rotation du corps 351 autour de son axe de rotation V. Le bord coupant 361A de chaque organe de dénudage 360 vient alors percer la gaine isolante 401 du conducteur électrique isolé 400 introduit dans le logement de réception 301 de ladite borne 300 pour venir au contact de l'âme conductrice 402 dudit conducteur. L'âme conductrice 402 étant réalisée dans un matériau métallique dur, l'organe de dénudage 360 prend appui sur celle-ci pour glisser dans la fente et sortir hors dudit corps 350 en direction de la branche libre 315B formant une rampe contre laquelle son bord de glissement 362 est déjà en appui. Tout en glissant sur cette rampe 315B l'organe de dénudage 360 exerce sur celle-ci une poussée qui plie élastiquement le coude 315A auquel elle est rattachée. En réaction, ladite branche libre 315B crée une contre-poussée sur l'organe de dénudage 360 si bien que son bord coupant 361A glisse continûment le long de l'âme conductrice 402 et tranche la gaine isolante 401 du conducteur 400.This pivoting movement of the actuating lever 356 causes the body 351 to rotate about its axis of rotation V. The cutting edge 361A of each stripping member 360 then pierces the insulating sheath 401 of the insulated electrical conductor 400 introduced into the housing receiving 301 of said terminal 300 to come into contact with the conductive core 402 of said conductor. The conductive core 402 being made of a hard metal material, the stripping member 360 bears on it to slide into the slot and out of said body 350 towards the free branch 315B forming a ramp against which its edge slide 362 is already in support. While sliding on this ramp 315B the stripping member 360 exerts on it a thrust that elastically bends the elbow 315A to which it is attached. In reaction, said free branch 315B creates a counter-thrust on the stripping member 360 so that its cutting edge 361A slides continuously along the conductive core 402 and cuts the insulating sheath 401 of the conductor 400.

Dans la position de connexion, le levier d'actionnement 356 s'étend selon l'axe du renfoncement 16 en retrait de la face arrière du boîtier 10. De cette manière, on évite qu'il soit accroché par un quelconque élément extérieur lors des manipulations ultérieures de l'appareillage électrique. Chaque organe de dénudage 360 s'étend perpendiculairement à l'axe du conducteur électrique isolé 400, il est bloqué entre, d'une part, l'âme conductrice 402 métallique dudit conducteur avec laquelle son extrémité portant le bord coupant 361A est en contact électrique, et, d'autre part, la branche libre 315B de la paroi 315 élastiquement déformable de la pièce monobloc 310 en U contre laquelle son autre extrémité 362 opposée est en appui en pliant élastiquement le coude 315A.In the connection position, the actuating lever 356 extends along the axis of the recess 16 recessed from the rear face of the housing 10. In this way, it is prevented from being hooked by any external element during subsequent manipulations of the electrical equipment. Each organ of stripping 360 extends perpendicularly to the axis of the insulated electrical conductor 400, it is blocked between, on the one hand, the conductive core 402 metal of said conductor with which its end bearing the cutting edge 361A is in electrical contact, and, on the other hand, the free branch 315B of the elastically deformable wall 315 of the one-piece piece 310 in U against which its other opposite end 362 is in abutment by elastically folding the bend 315A.

Avantageusement, le corps 151, 251, 351 porte à chacune de ses extrémités un flasque 155, 255, 355 qui s'étend orthogonalement à l'axe V de rotation, et qui dépasse de la paroi cylindrique du corps 151, 251, 351 sur un secteur angulaire d'environ 60 degrés. Ces flasques 155, 255, 355 permettent de maintenir latéralement le conducteur électrique isolé 400 lors de son perçage par l'organe de dénudage 160, 260, 360 afin qu'il ne sorte pas de ladite paroi en forme de gouttière 112, 212, 312.Advantageously, the body 151, 251, 351 carries at each of its ends a flange 155, 255, 355 which extends orthogonally to the axis V of rotation, and which protrudes from the cylindrical wall of the body 151, 251, 351 on an angular sector of about 60 degrees. These flanges 155, 255, 355 allow the insulated electrical conductor 400 to be held laterally during its drilling by the stripping member 160, 260, 360 so that it does not come out of said gutter-shaped wall 112, 212, 312 .
