The slot has lips (31,32) which are moulded with the casing and grip the conductor after being connected. The slot extends (29) without the lips above the contacts allowing the conductor to be withdrawn by simple force with for example a screwdriver. The height of the contacts is a multiple of the conductor diameter.

Description

La présente invention est relative à une connexion auto-dénudante à action rapide, applicable notamment à la réalisation d'un bornier de distribution permettant de raccorder à une barrette commune une pluralité de conducteurs, par autodénudage.The present invention relates to a fast-acting self-stripping connection, applicable in particular to the production of a distribution terminal block making it possible to connect a plurality of conductors to a common strip, by self-stripping.

Un but de la présente invention est de réaliser une connexion auto-dénudante dans laquelle la connexion des conducteurs peut être réalisée simplement, sans autre outil qu'un tournevis ordinaire , et rapidement, par une rotation du tournevis par exemple inférieure à 180°.An object of the present invention is to provide a self-stripping connection in which the connection of the conductors can be carried out simply, without any other tool than an ordinary screwdriver, and quickly, by a rotation of the screwdriver for example less than 180 °.

Un autre but de l'invention est de réaliser une connexion dans laquelle un simple tournevis permet de retirer les conducteurs déjà connectés.Another object of the invention is to provide a connection in which a simple screwdriver makes it possible to remove the conductors already connected.

L'invention a pour objet une connexion auto-dénudante pour la connexion de conducteurs à une barrette métallique munie de contacts auto-dénudants comprenant des bords parallèles affûtés, caractérisée en ce qu'elle comprend un moyen de poussage du conducteur sur lesdits contacts, actionné par tournevis.The invention relates to a self-stripping connection for connecting conductors to a metal strip provided with self-stripping contacts comprising sharpened parallel edges, characterized in that it comprises a means for pushing the conductor on said contacts, actuated by screwdriver.

Avantageusement, ledit moyen de poussage comprend un puits contenant une vis immobilisée en translation et dont la rotation sous l'action dudit tournevis provoque la translation axiale d'un poussoir fileté coopérant avec la vis et immobilisé en rotation.Advantageously, said pushing means comprises a well containing a screw immobilized in translation and whose rotation under the action of said screwdriver causes the axial translation of a threaded pusher cooperating with the screw and immobilized in rotation.

L'invention a également pour objet un bornier comprenant au moins une connexion auto-dénudante telle que définie ci-dessus.The invention also relates to a terminal block comprising at least one self-stripping connection as defined above.

Dans un mode particulier de réalisation, le bornier comprend un boîtier en plastique divisé en compartiments, chaque compartiment comprenant des contacts auto-dénudants, un puits muni d'une vis et d'un poussoir, une ouverture étant pratiquée dans le boîtier, pour chaque compartiment, entre la base du poussoir et lesdits contacts auto-dénudants, afin de permettre l'introduction d'un conducteur à connecter, ladite ouverture étant en communication avec une fente parallèle aux bords des contacts auto-dénudants.In a particular embodiment, the terminal block comprises a plastic box divided into compartments, each compartment comprising self-stripping contacts, a well provided with a screw and a pusher, an opening being made in the box, for each compartment, between the base of the pusher and said self-stripping contacts, to allow the introduction of a conductor to be connected, said opening being in communication with a slot parallel to the edges of the self-stripping contacts.

Selon une caractéristique importante de l'invention, ladite fente est munie de lèvres permettant le pincement du conducteur après connexion.According to an important characteristic of the invention, said slot is provided with lips allowing the conductor to be pinched after connection.

Avantageusement, lesdites lèvres sont venues de moulage avec le boîtier.Advantageously, said lips have come from molding with the housing.

Selon une autre caractéristique de l'invention, la hauteur des contacts auto-dénudants est égale à un multiple du diamètre des conducteurs à connecter.According to another characteristic of the invention, the height of the self-stripping contacts is equal to a multiple of the diameter of the conductors to be connected.

Avantageusement, ladite fente se prolonge, sans lèvres, au-dessous du niveau des contacts auto-dénudants, pour permettre l'extraction d'un conducteur par simple poussage, par exemple à l'aide dudit tournevis.Advantageously, said slot extends, without lips, below the level of the self-stripping contacts, to allow the extraction of a conductor by simple pushing, for example using said screwdriver.

L'invention est maintenant expliquée en détail par la description d'un mode de réalisation, en référence au dessin annexé dans lequel:

  • la figure 1 est une vue partielle en élévation d'un bornier mettant en oeuvre la connexion auto-dénudante de l'invention,
  • la figure 2 est une vue partielle de dessus du même bornier,
  • la figure 3 est une vue partielle en coupe selon la ligne III-III de la figure 1, à échelle agrandie par rapport aux figures 1 et 2,
  • la figure 4 est une vue partielle en coupe selon la ligne IV-IV de la figure 3, à échelle agrandie par rapport aux figures 1 et 2,
  • la figure 5 est une vue partielle en coupe selon la ligne V-V de la figure 3, à échelle agrandie par rapport aux figures 1 et 2.
The invention is now explained in detail by the description of an embodiment, with reference to the appended drawing in which:
  • FIG. 1 is a partial view in elevation of a terminal block implementing the self-stripping connection of the invention,
  • FIG. 2 is a partial top view of the same terminal block,
  • FIG. 3 is a partial sectional view along the line III-III of FIG. 1, on an enlarged scale compared to FIGS. 1 and 2,
  • FIG. 4 is a partial sectional view along the line IV-IV of FIG. 3, on an enlarged scale compared to FIGS. 1 and 2,
  • FIG. 5 is a partial sectional view along the line VV of FIG. 3, on an enlarged scale compared to FIGS. 1 and 2.

L'exemple décrit est celui d'un bornier de connexion, mais il faut bien comprendre que la connexion auto-dénudante à action rapide de l'invention peut s'appliquer à tout type d'appareil du domaine de la connectique.The example described is that of a connection terminal block, but it should be understood that the fast-acting self-stripping connection of the invention can be applied to any type of device in the field of connectors.

Le bornier comprend un boîtier en matière plastique, avantageusement constitué de deux portions emboîtables, référencées globalement A et B (voir Fig. 3). L'ensemble définit un boîtier sensiblement parallélépipédique comprenant une face avant 1, une face arrière 2, un sommet 3 et un fond 4 pouvant être solidarisé à un rail métallique de fixation 5. La partie A comporte la face 1, le fond 4 et la partie basse de la face 2. La partie B comprend le sommet 3 et la partie supérieure de la face 2. Le boîtier comprend des cloisons transversales 11 définissant une pluralité de compartiments parallèles 12 pouvant recevoir chacun un ou plusieurs conducteurs. Les cloisons 11 sont munies d'orifices en alignement permettant l'engagement d'une barrette métallique 13 (voir Fig. 3 à 5); c'est à cette barrette unique que devront être reliés électriquement les conducteurs.The terminal block includes a plastic casing, advantageously made up of two interlocking portions, generally referenced A and B (see Fig. 3). The assembly defines a substantially parallelepiped housing comprising a front face 1, a rear face 2, a top 3 and a bottom 4 which can be secured to a metal fixing rail 5. Part A comprises the face 1, the bottom 4 and the lower part of the face 2. The part B comprises the top 3 and the upper part of the face 2. The housing comprises transverse partitions 11 defining a plurality of parallel compartments 12 which can each receive one or more conductors. The partitions 11 are provided with aligned holes allowing the engagement of a metal bar 13 (see Fig. 3 to 5); the conductors must be electrically connected to this single bar.

La longueur du boîtier, ainsi que sa hauteur, dépendent du nombre de connexions à réaliser. A chaque extrémité du boîtier, une oreille 7 venue de moulage, permet la fixation du boîtier.The length of the housing, as well as its height, depends on the number of connections to be made. At each end of the housing, an ear 7 molded, allows the housing to be fixed.

Dans chaque compartiment, la barrette 13 est solidarisée à des contacts auto-dénudants (voir Fig. 5) désignés globalement dans la suite par la référence 16; ces contacts sont constitués par une plaque 16 repliée de manière à définir deux portions parallèles 16A et 16B terminées par des extrémités 16'A et 16'B convergentes dont les bords affûtés sont distants d'une longueur légèrement inférieure au diamètre du métal des conducteurs à connecter. La plaque 16 est solidarisée à la barrette par sertissage à des têtons 13A de la barrette d'une portion 16C convenablement repliée.In each compartment, the strip 13 is secured to self-stripping contacts (see FIG. 5) generally designated below by the reference 16; these contacts are constituted by a plate 16 folded back so as to define two parallel portions 16A and 16B terminated by converging ends 16'A and 16'B whose sharp edges are distant by a length slightly less than the diameter of the metal of the conductors to connect. The plate 16 is secured to the bar by crimping to pins 13A of the bar of a portion 16C suitably folded.

Le boîtier comprend, pour chaque compartiment 12, une portion en forme de puits 21. Ce puits est disposé au-dessus des contacts auto-dénudants 16 qui viennent d'être décrits, et contient une vis 22 ayant un corps 22A fileté et un tête 22B munie d'une fente 22C pouvant recevoir l'extrémité d'un tournevis 24. La tête de la vis est engagée entre deux rebords circulaires 21A et 21B de la pièce 21, de sorte que la vis peut tourner, mais qu'elle est immobilisée en translation; la vis est destinée à déplacer un poussoir 25 comprenant une portion prismatique 25A filetée intérieurement, vissée à la vis 22, et solidarisée par un fond 25B à une partie terminale prismatique 25C; la section du puits comprend deux faces opposées parallèles, il en est de même de la portion prismatique 25A; de la sorte, la pièce 25A est immobilisée en rotation et ne peut se déplacer qu'en translation axiale. La section de la pièce 25C, visible notamment dans la figure 5, est sensiblement celle d'un diabolo, la partie amincie pouvant s'engager entre les bords affûtés des contacts auto-dénudants. Cette disposition permet d'exercer une poussée régulièrement répartie sur le conducteur à connecter.The housing comprises, for each compartment 12, a portion in the form of a well 21. This well is disposed above the self-stripping contacts 16 which have just been described, and contains a screw 22 having a threaded body 22A and a head 22B provided with a slot 22C capable of receiving the end of a screwdriver 24. The head of the screw is engaged between two circular edges 21A and 21B of the part 21, so that the screw can rotate, but that it is immobilized in translation; the screw is intended to move a pusher 25 comprising a prismatic portion 25A internally threaded, screwed to the screw 22, and secured by a bottom 25B to a prismatic end portion 25C; the section of the well comprises two opposite parallel faces, it is the same for the prismatic portion 25A; in this way, the part 25A is immobilized in rotation and can only move in axial translation. The section of the part 25C, visible in particular in FIG. 5, is substantially that of a diabolo, the thinned part being able to engage between the sharp edges of the self-stripping contacts. This arrangement makes it possible to exert a regularly distributed thrust on the conductor to be connected.

La partie A du boîtier présente, pour chaque compartiment, un orifice latéral à entrée conique 27, pratiqué dans la face avant 1 du boîtier, et destiné à recevoir les conducteurs à connecter. Cet orifice est disposé entre la base du puits 21 et la partie supérieure des contacts auto-dénudants 16. Cet orifice est en communication avec une fente 28 qui s'étend au droit des contacts 16 et dont la longueur est choisie en fonction du nombre de conducteurs que l'on souhaite connecter dans le même compartiment. L'exemple choisi et illustré est celui où l'on peut connecter deux conducteurs dans le même compartiment.Part A of the housing has, for each compartment, a lateral orifice with conical inlet 27, formed in the front face 1 of the housing, and intended to receive the conductors to be connected. This orifice is disposed between the base of the well 21 and the upper part of the self-stripping contacts 16. This orifice is in communication with a slot 28 which extends in line with the contacts 16 and the length of which is chosen according to the number of conductors that you want to connect in the same compartment. The example chosen and illustrated is that where two conductors can be connected in the same compartment.

La fente 28 se prolonge en 29 au-dessous des contacts auto-dénudants, sur une longueur suffisante pour permettre l'extraction du conducteur, comme on le verra plus loin.The slot 28 extends at 29 below the self-stripping contacts, over a length sufficient to allow the extraction of the conductor, as will be seen below.

On note que les bords de la fente 28 sont munis, au droit des contacts 16, de lèvres élastiques 31 et 32, venues de préférence de moulage avec le boîtier, et destinées à serrer le conducteur après connexion.It will be noted that the edges of the slot 28 are provided, at the level of the contacts 16, with elastic lips 31 and 32, preferably coming from molding with the housing, and intended to clamp the conductor after connection.

La partie supérieure 3 de la partie B du boîtier est fermée par une barrette clipsée 34.The upper part 3 of the part B of the housing is closed by a clipped bar 34.

L'utilisation du bornier est la suivante:

  • on choisit un compartiment devant recevoir un conducteur;
  • on s'assure que le poussoir 25 est en position haute en manoeuvrant la vis;
  • on engage le conducteur 40 dans l'orifice 27 jusqu'à venir en butée sur la plaque 16C;
  • à l'aide d'un tournevis 24, on effectue une rotation de la vis 22, ce qui a pour effet de déplacer le poussoir 25 vers le bas, entraînant le conducteur entre les bords affûtés 16'A et 16'B des contacts auto-dénudants; une rotation de 140 degrés est normalement suffisante, si par exemple on a choisi une vis à 4 filets trapézoïdaux de pas égal à 14mm;
  • on effectue une rotation en sens inverse de la vis, ce qui a pour effet de remonter le poussoir;
  • on peut recommencer l'opération pour engager un second conducteur qui trouvera sa place en poussant le premier conducteur vers le bas de la connexion.
The use of the terminal block is as follows:
  • a compartment is chosen which must receive a conductor;
  • it is ensured that the pusher 25 is in the high position by maneuvering the screw;
  • the conductor 40 is engaged in the orifice 27 until it comes into abutment on the plate 16C;
  • using a screwdriver 24, the screw 22 is rotated, which has the effect of moving the pusher 25 downward, driving the conductor between the sharp edges 16'A and 16'B of the auto contacts - strippers; a rotation of 140 degrees is normally sufficient, if for example a screw with 4 trapezoidal threads with a pitch equal to 14mm has been chosen;
  • the screw is rotated in the opposite direction, which has the effect of raising the pusher;
  • we can repeat the operation to hire a second conductor who will find his place by pushing the first conductor down the connection.

On pourra recommencer ces opérations jusqu'à ce que le nombre maximal de conducteurs pour le compartiment choisi soit atteint.These operations can be repeated until the maximum number of conductors for the selected compartment is reached.

Pour extraire un conducteur, il suffira de pousser directement celui-ci à fond vers le bas, comme le montre la figure 3, à l'aide du même tournevis 24, et de le tirer à l'extérieur. On a noté en effet que les lèvres 31 et 32 s'arrêtent au-dessous de la connexion 16.To extract a conductor, it will suffice to directly push it completely down, as shown in FIG. 3, using the same screwdriver 24, and to pull it outside. It has in fact been noted that the lips 31 and 32 stop below the connection 16.

L'invention est de réalisation économique, grâce à un petit nombre de pièces moulées; son caractère modulaire permet de l'adapter à tous les besoins; son emploi est particulièrement aisé puisqu'il ne nécessite aucun des outils ou accessoires spéciaux habituellement nécessaires dans ce type de connexions.The invention is economical, thanks to a small number of molded parts; its modular nature allows it to be adapted to all needs; its use is particularly easy since it does not require any of the special tools or accessories usually required in this type of connection.
