Description

  • L'invention concerne les contacts électriques à pression et a pour objet un contact à pression à pouvoir de fermeture et d'ouverture incorporé.The invention relates to electrical pressure contacts and relates to a pressure contact with incorporated closing and opening power.
  • Un tel contact peut être utilisé dans divers dispositifs tels qu'un système modulaire, un interrupteur déconnectable unipolaire, etc., mais il est particulièrement recommandé pour l'équipement des prises de courant industrielles.Such a contact can be used in various devices such as a modular system, a single-pole disconnectable switch, etc., but it is particularly recommended for the equipment of industrial sockets.
  • En effet, les prises de courant industrielles doivent répondre aux règles définies par la publication 309-1 de la Commission Electrotechnique Internationale qui fixe en particulier, pour chaque calibre de prise de courant, un pouvoir de coupure minimum.Indeed, industrial sockets must comply with the rules defined by publication 309-1 of the International Electrotechnical Commission which in particular fixes, for each rating of socket, a minimum breaking capacity.
  • Dans les prises à contacts glissants (contacts par broches et alvéoles), la pression de contact est perpendiculaire au mouvement d'extraction de la broche, elle s'oppose à ce mouvement et le pouvoir de coupure est pratiquement inexistant. Pour répondre aux prescriptions susmentionnées, de telles prises devraient être verrouillées par un interrupteur.In sockets with sliding contacts (contacts by pins and cells), the contact pressure is perpendicular to the spindle extraction movement, it opposes this movement and the breaking capacity is practically nonexistent. To meet the above requirements, such sockets should be locked by a switch.
  • Dans les prises à contacts à pression, la pression de contact est parallèle au mouvement de séparation et favorise ce mouvement, il faut donc un moyen de verrouillage pour maintenir la pression de contact. Il suffit alors d'ajouter à ce moyen de verrouillage, un dispositif approprié de façon telle qu'au moment du déverrouillage les éléments de contact se séparent à une distance et avec une vitesse données, ce qui permet d'attein- dre très aisément les caractéristiques définies par la publication 309-1 de la C.E.I.. Cependant, certains pays, en particulier les Etats-Unis, demandent que les prises de courant industrielles aient un pouvoir de coupure comparable à celui d'un interrupteur, c'est-à-dire qu'elles atteignent les performances imposées aux interrupteurs par la publication 408 de la C.E.L. Avec les contacts à pression en bout actuellement existants, les prises de courant ne peuvent satisfaire à cette exigence car, au moment du déverrouillage et avant que les éléments de contact ne se séparent, la pression de contact qui était de quelques kilos, diminue pour devenir nulle au moment de la séparation et la vitesse de séparation est limitée par l'inertie du système.In pressure contact sockets, the contact pressure is parallel to the separation movement and promotes this movement, so a locking means is required to maintain the contact pressure. It then suffices to add to this locking means, an appropriate device such that at the time of unlocking the contact elements separate at a given distance and with a given speed, which makes it very easy to reach the characteristics defined by IEC publication 309-1 However, some countries, in particular the United States, require that industrial sockets have a breaking capacity comparable to that of a switch, ie to say that they reach the performances imposed on the switches by publication 408 of the CEL With current pressure contacts at the end, current sockets cannot meet this requirement because, at the time of unlocking and before the contact elements separate, the contact pressure, which was a few kilos, decreases to become zero at the time of separation and the separation speed is limited by the inertia of the system.
  • Deux types de contacts à pression sont actuellement utilisés:
    • - pour des intensités inférieures à 250 ampères, ces contacts comportent un contact élastique ayant une tête mobile montée sur un ressort et reliée électriquement à un plot fixe de raccordement des conducteurs par une tresse coaxiale avec le ressort,
    • - pour les intensités supérieures à 250 ampères, ces contacts comportant une bascule qui travaille perpendiculairement à la ligne des éléments de contact.
    Two types of pressure contacts are currently used:
    • - for intensities lower than 250 amperes, these contacts include an elastic contact having a movable head mounted on a spring and electrically connected to a fixed stud for connecting the conductors by a braid coaxial with the spring,
    • - for intensities greater than 250 amps, these contacts comprising a rocker which works perpendicular to the line of the contact elements.
  • Dans les appareillages électriques comportant une bascule, qu'il s'agisse d'une prise de courant (voir par exemple CH-A-356812) ou un interrupteur (tel que l'interrupteur à poussoir du DE-B-1242735), la bascule effectue lors de la rupture le mouvement inverse de celui de fermeture. Une telle disposition peut permettre d'obtenir un pouvoir de coupure convenable mais le pouvoir de fermeture est insuffisant.In electrical equipment comprising a rocker, whether it is an electrical outlet (see for example CH-A-356812) or a switch (such as the push-button switch of DE-B-1242735), the flip-flop performs the reverse movement when closing. Such an arrangement can make it possible to obtain a suitable breaking capacity but the closing power is insufficient.
  • L'invention fournit un troisième type de contacts à pression capable de conférer à ceux-ci le pouvoir de coupure d'un interrupteur, en réalisant une bascule qui travaille parallèlement à la ligne des éléments de contact et qui poursuit lors de la coupure, la trajectoire suivie à la fermeture, sans point de rebroussement.The invention provides a third type of pressure contact capable of giving them the breaking capacity of a switch, by producing a rocker which works parallel to the line of the contact elements and which continues during the breaking, the trajectory followed on closing, without turning point.
  • Un tel système présente naturellement, par rapport aux contacts utilisant une tresse, tous les avantages du contact à bascule, à savoir:
    • a) la chute de tension du dispositif est garantie dans le temps puisque, contrairement au dispositif à tresse, les chutes de tension qui peuvent varier n'existent qu'au point de contact,
    • b) les inconvénients de la brasure ou du sertissage de la tresse sont supprimés,
    • c) la section de la bascule peut-être au moins égale au plus gros conducteur pouvant être raccordé dans l'appareil,
    • d) il y a un fort auto-nettoyage des contacts, résultant du mouvement de la bascule.
    Compared to contacts using a braid, such a system naturally has all the advantages of rocking contact, namely:
    • a) the voltage drop of the device is guaranteed over time since, unlike the braided device, the voltage drops which can vary only exist at the point of contact,
    • b) the disadvantages of brazing or crimping the braid are eliminated,
    • c) the section of the scale may be at least equal to the largest conductor that can be connected in the device,
    • d) there is a strong self-cleaning of the contacts, resulting from the movement of the rocker.
  • En outre, ici, chaque contact devient un interrupteur unipolaire à ouverture et fermeture brusques et indépendantes de la manoeuvre de l'opérateur.In addition, here, each contact becomes a single-pole switch with sudden opening and closing and independent of the operator's operation.
  • Selon l'invention, le contact à pression destiné à assurer la liaison électrique entre une broche conductrice portée rigidement par le support isolant d'une fiche et un plot fixe relié électriquement à une borne d'arrivée et disposé dans un puits ménagé dans le support isolant d'un socle, lorsque le broche de fiche est introduite axialement dans le puits du socle, les corps de la fiche et du socle portant des moyens conjugués de guidage et de verrouillage pour assurer .puis maintenir cette introduction, est remarquable en ce qu'il comporte une pièce conductrice rigide et mobile, disposée dans le puits du socle, s'étendant sur une partie de la profondeur de ce dernier, et destinée à être repoussée vers le fond du puits par l'extrémité libre de la broche prenant appui sur un talon d'extrémité de ladite pièce, à l'encontre d'un moyen élastique qui tend à appliquer ledit talon contre l'orifice du puits, que des moyens de guidage sont prévus pour assurer à la pièce mobile un déplacement sensiblement parallèle à l'axe du contact jusqu'à ce que son extrémité opposée au talon arrive au niveau du plot relié à la borne d'arrivée et que la pièce mobile et les moyens de guidage sont aménagés de façon telle qu'à la fin de ce déplacement parallèle à l'axe, la pièce mobile échappe auxdits moyens pour basculer et venir s'appliquer brusquement contre le plot sous l'action d'un moyen élastique, tandis que ce dernier moyen élastique contribue à assurer la rupture brusque du contact, lors du retrait de la broche de fiche, en accentuant le basculement de la pièce mobile.According to the invention, the pressure contact intended to ensure the electrical connection between a conductive pin rigidly carried by the insulating support of a plug and a fixed stud electrically connected to an arrival terminal and disposed in a well formed in the support insulator of a base, when the plug pin is inserted axially into the well of the base, the bodies of the plug and of the base carrying combined guide and locking means to ensure. then maintain this introduction, is remarkable in that '' it comprises a rigid and movable conductive part, disposed in the well of the base, extending over part of the depth of the latter, and intended to be pushed towards the bottom of the well by the free end of the spindle bearing on an end heel of said piece, against an elastic means which tends to apply said heel against the orifice of the well, that guide means are provided to ensure that the moving part is displaced so parallel to the contact axis until its end opposite the heel reaches the level of the stud connected to the arrival terminal and the moving part and the guide means are arranged in such a way that at the end from this displacement parallel to the axis, the moving part escapes said means for tilting and abruptly coming to bear against the stud under the action of an elastic means, while the latter elastic means contributes to ensuring the abrupt rupture of the contact , when removing the plug pin, accentuating the tilting of the moving part.
  • On réalise ainsi un véritable interrupteur à ouverture et fermeture brusques tout en permettant des pressions de contact fortes et en respectant les règles de sécurité puisque le plot fixe, sous tension, ne peut être atteint accidentellement puisqu'il n'est accessible qu'en repoussant la pièce mobile.We thus realize a real switch with abrupt opening and closing while allowing both strong contact pressures and respecting the safety rules since the fixed stud, under tension, cannot be accidentally reached since it is accessible only by pushing the moving part.
  • L'invention sera mieux comprise à la lecture de la description qui va suivre d'un de ses modes de réalisation, description qui se réfère aux dessins annexés dans lesquels;
    • - la figure 1 est une perspective en coupe partielle d'un contact selon l'invention, et
    • - les figures 2A à 2F des représentations schématiques, à plus petite échelle, les différentes phases de fonctionnement de la pièce mobile lors des manoeuvres d'enfoncement et de dégagement de la broche.
    The invention will be better understood on reading the following description of one of its embodiments, description which refers to the accompanying drawings in which;
    • FIG. 1 is a perspective in partial section of a contact according to the invention, and
    • - Figures 2A to 2 F schematic representations, on a smaller scale, the different phases of operation of the moving part during the driving in and out of the spindle.
  • Sur les dessins, un contact à pression en bout est destiné à assurer la liaison électrique entre une broche conductrice 11 portée rigidement par le support isolant d'une fiche (non représentée) et un plot fixe 12 relié électriquement par une lame conductrice 13 à une borne d'arrivée (non représentée). Le plot fixe 12 est disposé dans un puits 14, ménagé dans le support isolant 15 d'un socle non autrement représenté, et présentant un orifice 16 permettant l'introduction axiale de la broche 11. Cette liaison électrique entre les éléments 11 et 12 est réalisée par le déplacement longitudinal guidé, suivi d'un basculement, d'une pièce conductrice 17 rigide disposée dans le puits 14 et s'étendant sur une partie de la profondeur dudit puits 14.In the drawings, an end pressure contact is intended to provide the electrical connection between a conductive pin 11 rigidly carried by the insulating support of a plug (not shown) and a fixed stud 12 electrically connected by a conductive blade 13 to a arrival terminal (not shown). The fixed stud 12 is disposed in a well 14, formed in the insulating support 15 of a base not otherwise shown, and having an orifice 16 allowing the axial introduction of the pin 11. This electrical connection between the elements 11 and 12 is produced by the guided longitudinal displacement, followed by a tilting, of a rigid conductive part 17 disposed in the well 14 and extending over part of the depth of said well 14.
  • Dans l'exemple représenté la pièce conductrice mobile 17, est constituée par une plaquette (voir notamment figure 1 ) dont l'une des extrémités est courbée deux fois à 90° pour former un talon 18 en U et dont l'autre extrémité, qui porte un plot 19 destiné à coopérer avec le plot fixe 12, présente des appendices latéraux 20 lui donnant une configuration en T.In the example shown the movable conductive part 17, is constituted by a plate (see in particular Figure 1), one end of which is bent twice at 90 ° to form a heel 18 in a U shape and the other end of which carries a stud 19 intended to cooperate with the fixed stud 12, has lateral appendages 20 giving it a T-shaped configuration.
  • Au repos (figure 2A), c'est à dire après retrait de la broche 11, la pièce 17 est sollicitée vers l'extérieur du puits 14, son talon 18 venant s'appliquer contre l'orifice 16, sous l'action d'un ressort de torsion à boudin 21 dont une branche d'extrémité est engagée dans le U formé par le talon 18 et l'autre calée et maintenue contre la paroi interne du puits 14.At rest (Figure 2A), that is to say after removal of the spindle 11, the part 17 is biased towards the outside of the well 14, its heel 18 coming to bear against the orifice 16, under the action of 'a torsion spring with coil 21, one end branch of which is engaged in the U formed by the heel 18 and the other wedged and held against the internal wall of the well 14.
  • Dans le puits 14 sont disposées transversalement, dans le prolongement l'une de l'autre, deux pattes 22 espacées de la paroi 23 du puits le long de laquelle doit se déplacer longitudinalement la pièce 17. L'écartement entre les bords en regard des deux pattes 22 est supérieur à la largeur de la partie médiane de la pièce 17, mais inférieur à la largeur de l'extrémité en T de ladite pièce.In the well 14 are arranged transversely, in the extension of one another, two tabs 22 spaced from the wall 23 of the well along which the piece 17 must move longitudinally. The spacing between the edges opposite the two legs 22 is greater than the width of the middle part of the part 17, but less than the width of the T-shaped end of said part.
  • Un second ressort de torsion à boudin 24 est destiné à agir sur la pièce 17, l'une de ses branches d'extrémité étant appliquée contre ladite pièce sur sa face tournée vers la paroi 23 et le boudin étant disposé dans le U formé par le talon 18. Avantageusement, la branche d'extrémité du ressort 21 engagée dans ce U, est disposée à l'intérieur du boudin du ressort 24 et assure ainsi le maintien de ce dernier.A second torsion coil spring 24 is intended to act on the part 17, one of its end branches being applied against said part on its face facing the wall 23 and the tube being placed in the U formed by the heel 18. Advantageously, the end branch of the spring 21 engaged in this U, is disposed inside the coil of the spring 24 and thus ensures the maintenance of the latter.
  • Dans la position de repos (fig. 2A) susmentionnée, l'extrémité en T, avecv son plot 19, de la pièce 17, est située à un niveau inférieur à celui des pattes 22, l'axe du contact étant supposé vertical comme sur le dessin, et la seconde branche d'extrémité du ressort 24 est libre de toute contrainte.In the above-mentioned rest position (FIG. 2A), the T-shaped end, with its stud 19, of the part 17, is located at a level below that of the legs 22, the axis of the contact being assumed to be vertical as on the drawing, and the second end branch of the spring 24 is free from any constraint.
  • Lorsque la broche 11 est introduite dans l'orifice 16 du puits 14, son extrémité libre vient s'appliquer contre le talon 18 de la pièce 17 et lorsque la manoeuvre d'introduction se poursuit la dite pièce est repoussée vers le fond du puits. Dans un premier temps (figure 28), les appendices 20 de la pièce 17 s'engagent entre la paroi 23 et les pattes de guidage 22 et, en même temps, l'extrémité libre du ressort 24 vient s'arc-bouter contre une saillie interne 25 du puits 14, saillie servant également au maintien du ressort 21.When the pin 11 is introduced into the orifice 16 of the well 14, its free end comes to bear against the heel 18 of the part 17 and when the insertion maneuver continues the said part is pushed back towards the bottom of the well. Firstly (FIG. 28), the appendages 20 of the part 17 engage between the wall 23 and the guide tabs 22 and, at the same time, the free end of the spring 24 is braced against a internal projection 25 of the well 14, projection also serving to hold the spring 21.
  • L'introduction de la broche 11 se poursuivant, la pièce 17 se déplace, sensiblement parallèlement à elle-même, vers le fond du puits, les appendices 20 étant fermement appliqués contre les pattes 22 par l'action du ressort 24 (figure 2C).The introduction of the spindle 11 continuing, the part 17 moves, substantially parallel to itself, towards the bottom of the well, the appendages 20 being firmly applied against the legs 22 by the action of the spring 24 (FIG. 2C) .
  • L'ensemble est aménagé de façon telle que le plot 19 de la pièce 17 arrive au niveau du plot fixe 12, au moment où les appendices 20 dépassent le bord supérieur des pattes 22 (figure 2C et figure 1). Alors, sous l'action du ressort 24, la pièce 17 qui n'est plus retenue par les pattes 22, bascule vers la paroi du puits opposée à la paroi 23 et le plot 19 vient s'appliquer brusquement contre le plot fixe 22 (figure 2D) réalisant ainsi la fermeture brusque du contact.The assembly is arranged in such a way that the stud 19 of the part 17 arrives at the level of the fixed stud 12, at the moment when the appendages 20 exceed the upper edge of the lugs 22 (FIG. 2C and FIG. 1). Then, under the action of the spring 24, the part 17 which is no longer retained by the lugs 22, tilts towards the wall of the well opposite the wall 23 and the stud 19 abuts abruptly against the fixed stud 22 ( Figure 2D) thus achieving the abrupt closure of the contact.
  • Bien entendu, à ce même moment, intervient un verrouillage immobilisant la broche 11. Ce verrouillage est obtenu par tout moyen connu, généralement par immobilisation relative de la fiche solidaire de la broche 11 par rapport au socle dans lequel est situé le puits 14, par exemple par une liaison à baïonnette.Of course, at this same moment, a locking action takes place immobilizing the pin 11. This locking is obtained by any known means, generally by relative immobilization of the plug secured to the pin 11 relative to the base in which the well 14 is located, by example by a bayonet link.
  • Après déverrouillage, l'extraction de la broche 11 s'effectue par simple traction axiale. Le mouvement est facilité par l'action du ressort 21 qui, en maintenant le talon 18 contre l'extrémité de la broche 11, tend à chasser cette dernière hors du puits. Au début de la manoeuvre (figure 2E) le plot 19, toujours en appui élastique contre le plot fixe 12, grâce au ressort 24, glisse sur ledit plot 12 entrainant ainsi un auto-nettoyage des portées de contact. Avantageusement, pour assurer un fort auto-nettoyage les plots 12 et 19 sont hémicylindriques.After unlocking, the pin 11 is extracted by simple axial traction. The movement is facilitated by the action of the spring 21 which, by holding the heel 18 against the end of the pin 11, tends to drive the latter out of the well. At the start of the maneuver (FIG. 2E) the stud 19, still in elastic support against the fixed stud 12, by means of the spring 24, slides on said stud 12 thus causing self-cleaning of the contact surfaces. Advantageously, to ensure strong self-cleaning, the studs 12 and 19 are semi-cylindrical.
  • L'extraction de la broche 11 se poursuivant, la pièce 17 continue à la suivre en direction de l'orifice 16 du puits et à un moment donné, le plot 19 échappe au plot 12 et, sous l'action du ressort 24, bascule brutalement vers la paroi opposée à la paroi 23 (figure 2F) déterminant une ouverture brusque du contact. En même temps, la branche d'extrémité du ressort 24 s'éloigne de la saillie 25 et le dit ressort 24 devenant libre de toute contrainte, la pièce 17 n'est plus soumise qu'à l'action du ressort 21 qui applique alors la partie antérieure courbe du talon 18 contre l'extrémité de la broche 11. Le point de contact n'est pas à l'aplomb de la branche d'extrémité du ressort 21 et la pièce 17 tendà se redresser, la courbure du talon 18 facilitant ce mouvement et, à la fin de sa course, la pièce 17 vient s'appliquer par son talon sur l'orifice du puits reprenant sa position de repos (figure 2A) dans l'attente d'une nouvelle introduction de la broche 11. Cependant d'autres moyens peuvent être imaginés pour guider le redressement de la pièce 17.The extraction of the spindle 11 continues, the part 17 continues to follow it in the direction of the orifice 16 of the well and at a given moment, the stud 19 escapes from the stud 12 and, under the action of the spring 24, switches suddenly towards the wall opposite wall 23 (FIG. 2F) determining an abrupt opening of the contact. At the same time, the end branch of the spring 24 moves away from the projection 25 and the said spring 24 becomes free of any constraint, the part 17 is no longer subjected only to the action of the spring 21 which then applies the curved front part of the heel 18 against the end of the spindle 11. The contact point is not perpendicular to the end branch of the spring 21 and the part 17 tends to straighten, the curvature of the heel 18 facilitating this movement and, at the end of its stroke , the part 17 is applied by its heel to the orifice of the well resuming its rest position (Figure 2A) pending a new introduction of the pin 11. However, other means can be devised to guide the recovery of room 17.
  • Ainsi le contact est devenu un véritable interrupteur unipolaire à ouverture et fermeture brusques.Thus the contact has become a real single-pole switch with abrupt opening and closing.
  • Tout ce qui précède se rapport à un contact isolé, mais il est évident qu'une pluralité de tels contacts permet de réaliser différents dispositifs et, notamment, des prises de courant dans lesquels chaque contact, à l'exception éventuellement d'un contact de terre s'il existe, joue le rôle d'interrupteur et cela indépendamment de tous les aménagements connus susceptibles d'être utilisés (déclage angulaire d'au moins un contact, supports isolants à position angulaire variable, disque de sécurité simple ou double, etc.).All of the above relates to an isolated contact, but it is obvious that a plurality of such contacts makes it possible to produce different devices and, in particular, sockets in which each contact, with the possible exception of a contact of earth if it exists, plays the role of switch and this independently of all known arrangements which may be used (angular release of at least one contact, insulating supports with variable angular position, single or double safety disc, etc. .).
