Description

La présente invention concerne une borne à vis associée à une pièce conductrice d'un appareil électrique pour connecter à cette pièce au moins un conducteur électrique.The present invention relates to a screw terminal associated with a conductive part an electrical apparatus for connecting at least one electrical conductor to this part.

Elle vise plus précisément une borne à vis du type comprenant une cage de connexion dotée d'un orifice taraudé, une vis présentant une tête et une queue filetée coopérant avec l'orifice taraudé, et une pièce de pression élastique qui doit s'appliquer sur le conducteur électrique. La cage et/ou la vis sont déplaçables dans un logement de l'appareil, et la pièce de pression comprend une plage de tête et une plage de pression reliées entre elles par une aile élastique propre à emmagasiner une énergie de serrage, la plage de tête pouvant être sollicitée par la tête de vis et la plage de pression étant applicable contre un conducteur ou contre la pièce conductrice de l'appareil.It is more specifically a screw terminal of the type comprising a connection cage equipped with a tapped hole, a screw having a head and a threaded tail cooperating with the threaded orifice, and a piece of elastic pressure which must apply on the electrical conductor. The cage and / or the screw are movable in a housing, and the pressure piece includes a headband and a pressure range interconnected by a resilient elastic wing to store a clamping energy, the head range can be solicited by the screw head and the pressure range being applicable against a conductor or against the conductive part of the device.

Le document DE U 1 935 560 décrit une telle borne. Une pièce de pression en forme d'étrier en U, comportant une aile haute et une aile basse reliées par une âme, est engagée par l'aile haute sous la tête de la vis et est applicable par l'aile basse contre un conducteur introduit dans la cage ; l'âme de l'étrier est un peu plus haute que la longueur de la partie filetée afin de procurer une mise en pression de la pièce. Cette mise en pression permet, par l'appui exercé sous la tête de vis, d'éviter le desserrage de la borne et/ou, après application du pied de vis contre l'aile basse, de rattraper le fluage du conducteur serré par la borne.DE 1 935 560 discloses such a terminal. A pressure piece in U-shaped stirrup shape, comprising a high wing and a low wing connected by a soul, is engaged by the high wing under the head of the screw and is applicable by the wing low against a driver introduced into the cage; the soul of the stirrup is a bit more high than the length of the threaded portion to provide a pressurized the room. This pressurization allows, by the support exerted under the screw head, to avoid loosening the terminal and / or, after applying the screw foot against the wing low, to catch the creep of the driver tightened by the terminal.

Cependant la forme en U de la pièce de pression entraíne un déséquilibre lors de la mise en oeuvre de la borne.However, the U-shape of the pressure piece causes an imbalance during the implementation of the terminal.

Le document DE 40 13 225 illustre aussi une borne à vis dotée d'une pièce de pression en forme de cage fermée dont le mode de déformation n'est pas précisé. Document DE 40 13 225 also illustrates a screw terminal provided with a piece of closed cage pressure whose mode of deformation is not specified.

L'invention a pour but d'améliorer l'équilibrage d'une borne à vis du type décrit, tout en assurant à la pièce de pression un mode de déformation avantageux tant pour l'encombrement de la borne que pour le respect de la limite élastique de la pièce de pression.The object of the invention is to improve the balancing of a screw terminal of the type described, while by providing the pressure piece with an advantageous mode of deformation both for the congestion of the terminal that for the respect of the elastic limit of the room of pressure.

Selon l'invention, la pièce de pression comprend deux ailes élastiques symétriques par rapport à un plan axial de la vis, les ailes élastiques sont de forme concave et la plage de tête est sollicitée par la tête de vis de manière à mettre symétriquement la pièce de pression en compression lors du serrage de la vis. La pièce de pression forme avantageusement un anneau entrelacé avec la cage rigide.According to the invention, the pressure piece comprises two symmetrical elastic wings relative to an axial plane of the screw, the elastic wings are of concave shape and the headband is solicited by the screw head so as to symmetrically pressure piece in compression when tightening the screw. The pressure piece advantageously forms an interlaced ring with the rigid cage.

L'agencement de la pièce de pression est de préférence tel que les ailes élastiques concaves se déforment avec une concavité qui se réduit quand la contrainte exercée par la vis augmente. La plage de tête présente une forme pentue ou convexe, et la tête de vis sollicite la plage de tête à faible distance de l'axe de la vis, de manière à favoriser l'effet indiqué de réduction de la concavité latérale. La pièce de pression peut être engagée sur le col de la vis au moyen d'une plage de montage à deux demi-secteurs circulaires et peut comporter ― ou coopérer avec - des éléments assurant un maintien de la borne en position ouverte et une isolation améliorée du côté de l'ouverture d'introduction du conducteur.The arrangement of the pressure piece is preferably such that the elastic wings concaves are deformed with a concavity which is reduced when the constraint exerted by the screw increases. The headband has a sloping or convex shape, and the screw head biases the head range a short distance from the axis of the screw, so to promote the indicated effect of reducing lateral concavity. The room pressure can be engaged on the neck of the screw by means of a mounting range to two circular half-sectors and may comprise - or cooperate with - elements Keeping the terminal in the open position and improved insulation on the side of the introduction opening of the driver.

La description va être faite ci-après d'un mode de réalisation non limitatif de l'invention, en regard des dessins annexés.The description will be made hereinafter of a non-limiting embodiment of the invention, with reference to the accompanying drawings.

La figure 1 est une vue schématique en coupe partielle de la borne à vis selon l'invention.Figure 1 is a schematic partial sectional view of the screw terminal according to the invention.

La figure 2 est une vue de côté de la borne de la figure 1.Figure 2 is a side view of the terminal of Figure 1.

La figure 3 est une vue de dessus de la borne de la figure 1, avec coupe partielle selon III-III.FIG. 3 is a view from above of the terminal of FIG. 1, with partial section according to III-III.

La figure 4 illustre le fonctionnement de la borne à vis. Figure 4 illustrates the operation of the screw terminal.

La borne à vis A représentée est destinée à être logée dans un appareil électrique. Les seuls éléments de l'appareil représentés sur la figure 1 sont le logement isolant 10 prévu pour la borne et une branche fixe de contact de la pièce électrique conductrice rigide 11 contre laquelle on souhaite serrer un ou plusieurs conducteurs ; ainsi, deux conducteurs C1,C2 susceptibles d'être introduits respectivement audessus et au-dessous de la branche sont représentés figure 1. Le logement 10 est situé dans l'appareil, cela signifiant qu'il est prévu dans une partie du boítier de l'appareil ou dans un bornier rapporté au boítier de l'appareil.The screw terminal A shown is intended to be housed in an electrical device. The only elements of the apparatus shown in FIG. 1 are the insulating housing 10 provided for the terminal and a fixed branch of contact of the conductive electrical part rigid 11 against which it is desired to tighten one or more conductors; thus, two drivers C1, C2 may be introduced respectively above and below the branch are shown in Figure 1. Housing 10 is located in the device, this means that it is provided in a part of the housing of the device or in a terminal box attached to the housing of the device.

La borne A comprend une cage 12 de type bien connu, formée par une portion de bande métallique découpée et pliée pour se boucler en anneau rigide et sensiblement rectangulaire. La cage rigide 12 comporte sur un petit côté 12a un orifice taraudé 12b et la branche de contact de la pièce conductrice 11 est engagée transversalement dans l'ouverture allongée 12c, par exemple sensiblement rectangulaire, de la cage 12.Terminal A comprises a cage 12 of well-known type, formed by a portion of metal strip cut and folded to curl into a rigid ring and substantially rectangular. The rigid cage 12 has on a small side 12a a threaded orifice 12b and the contact leg of the conductive part 11 is engaged transversely in the elongate opening 12c, for example substantially rectangular, of the cage 12.

La vis 20 comprend une tête de manoeuvre 21, une tige filetée 22 et un col 23 reliant la tige filetée à la tête. La tige filetée, ou un prolongement non fileté de cette tige, se termine à son extrémité libre par une portée 24.The screw 20 comprises an operating head 21, a threaded rod 22 and a neck 23 connecting the threaded rod to the head. The threaded rod, or an unthreaded extension of this stem, ends at its free end by a span 24.

Une pièce de pression 30 est couplée à la vis 20 de manière à se déplacer avec elle. La pièce 30 est une pièce unitaire élastique, sensiblement fermée sur elle-même en forme d'anneau et symétrique par rapport à un plan axial P de la vis . Elle comprend une plage de tête 31 située sous la tête 21 et enserrant le col 23 de la vis, une plage de pression 32 applicable sur le conducteur C1 ou la branche de contact de la pièce conductrice 11 et, de chaque côté de l'axe de la vis, une aile concave 33,34 qui se raccorde aux plages 31,32 par une zone de raccordement déterminant un angle saillant 35. La concavité des ailes (voir cette concavité en vue latérale sur les figures 1 et 4) est telle qu'elles se rapprochent en leur milieu de l'axe de la vis. La plage de tête 31 comprend deux demi-secteurs circulaires 31a,31b qui s'engagent dans le col 23 de la vis et assurent ainsi un maintien équilibré de la pièce 30. Les demi-secteurs composant la plage de tête 31 sont orientés de façon à remonter vers la tête de la vis, en donnant une forme générale pentue ou convexe à la plage de tête, et la plage 31 se termine au-delà des demi-secteurs par des rabattements axiaux jointifs 31 c qui se rejoignent selon le plan axial P de la vis.A pressure piece 30 is coupled to the screw 20 so as to move with she. The piece 30 is an elastic unitary piece, substantially closed on itself ring-shaped and symmetrical with respect to an axial plane P of the screw. She comprises a head area 31 located under the head 21 and enclosing the neck 23 of the screw, a pressure range 32 applicable on the driver C1 or the branch of contact of the conductive part 11 and, on each side of the axis of the screw, a wing concave 33,34 which is connected to the ranges 31,32 by a connection zone defining a protruding angle 35. The concavity of the wings (see this concavity in view lateral view in FIGS. 1 and 4) is such that they are approaching in the middle of the axis of the screw. The head beach 31 comprises two circular half-sectors 31a, 31b which engage in the neck 23 of the screw and thus ensure a balanced maintenance of the 30. The half-sectors comprising the head region 31 are oriented so as to go back to the head of the screw, giving a generally sloping or convex shape to the head beach, and the beach 31 ends beyond the half-sectors by drawdowns axial contiguous 31 c which meet in the axial plane P of the screw.

La plage de pression 32 est incurvée pour donner une forme générale convexe à la partie inférieure de la pièce 30 et présente des reliefs 32a coopérant avec une partie en retrait 11 a de la pièce conductrice 11.The pressure range 32 is curved to give a generally convex shape to the lower part of the piece 30 and has reliefs 32a cooperating with a part recessed 11a of the conductive part 11.

Comme on le voit sur les figures 1 et 4, la pièce 30 est agencée pour que la concavité de ses ailes 33,34, en combinaison avec la forme pentue ou convexe de ses plages 31,32, lui permette de se déformer par compression, avec une courbure qui diminue quand la pression augmente. On notera que la diminution de concavité s'accompagne du maintien de la pièce 30 dans le gabarit a défini par les angles saillants 35, ce gabarit étant lui-même ― par nécessité de guidage ― inférieur à la largeur b du logement 10.As seen in Figures 1 and 4, the part 30 is arranged so that the concavity of its wings 33,34, in combination with the sloping or convex shape of its ranges 31,32, allows it to deform by compression, with a curvature that decreases as the pressure increases. Note that the concavity of reduction is accompanied by the holding part 30 in the template defined by the sharp edges 35, this template being itself - by necessity guide - less than the width b of the housing 10.

Au repos, une faible distance c est prévue entre la portée d'appui 24 de la vis et la face interne en regard 32a de la plage de pression 32, cette distance c étant déterminée pour que son rattrapage produise le niveau souhaité de contrainte de la pièce de pression. La distance minimale d (observée au repos) entre les faces internes 33a,34a des ailes 33,34 est légèrement supérieure à la largeur e de la cage 12, de manière que la cage puisse glisser librement entre les ailes ou vice versa. La tête 21 de la vis s'applique sur la plage de tête 31 de la pièce de pression dans une région située à une faible distance f de l'axe de la vis, de manière à créer via la plage 31 un bras de levier qui accentue le couple exercé sur la pièce 30.At rest, a small distance c is provided between the bearing surface 24 of the screw and the internal face 32a of the pressure range 32, this distance c being determined so that its catching produces the desired level of stress of the pressure piece. The minimum distance d (observed at rest) between the inner faces 33a, 34a of the wings 33,34 is slightly greater than the width e of the cage 12, so that the cage can slide freely between the wings or vice versa. The head 21 of the screw is applied to the head region 31 of the pressure member in a region at a short distance f from the axis of the screw, so as to create via the range 31 a lever arm which accentuates the torque exerted on the piece 30.

Le logement isolant 10 présente sur ses parois internes au moins une saillie de maintien 10a qui coopère avec l'avancée formée à l'angle supérieur de la pièce de pression pour retenir la borne en position ouverte. D'autre part, une bavette isolante 36 qui réduit les risques de contact intempestif est fixée sur l'aile 34, de façon à se déplacer avec la pièce de pression et à masquer en partie une ouverture d'introduction de conducteur. Des zones poinçonnées de décompression 36 peuvent être prévues dans la région fortement sollicitée des angles 35. The insulating housing 10 has on its inner walls at least one protrusion of 10a that cooperates with the advance formed at the upper corner of the room pressure to hold the terminal in the open position. On the other hand, an insulating bib 36 which reduces the risk of inadvertent contact is fixed on the wing 34, so as to move with the pressure piece and partially obscure an opening opening of driver. Punctured zones of decompression 36 can be provided in the region strongly stressed angles 35.

Le fonctionnement de la borne va maintenant être décrit. On notera que, suivant l'appareil auquel la borne est associée, celle-ci serre un conducteur supérieur C1 ou un conducteur inférieur C2 ou deux conducteurs C1 et C2 ; les mouvements de translation de la vis et de la cage sont variables selon les cas d'utilisation.The operation of the terminal will now be described. It will be noted that, following the device to which the terminal is associated, this clamps an upper conductor C1 or a lower conductor C2 or two conductors C1 and C2; movements of translation of the screw and the cage are variable depending on the use case.

Au serrage d'un conducteur C1 par exemple, la rotation de la vis entraíne, par coopération de son filetage avec l'orifice taraudé 12b, la montée de la cage 12 jusqu'à sa butée contre la face inférieure de la branche conductrice fixe 11, ainsi que la descente de la vis relativement à la cage 12, et au logement 10. Cette descente s'effectue jusqu'à butée de l'aire inférieure de la plage de pression 32 contre la face en regard de la branche 11. La poursuite de la rotation de la vis entraíne alors la mise en contrainte par compression de la pièce de pression 30, qui se traduit par la diminution de la concavité des ailes 33,34 et l'application de la portée 24 de la vis contre la face interne 32a de la plage de pression 32 (situation indiquée en tirets sur la partie gauche de la figure 4). Il convient de noter que la tête de vis sollicite la plage de tête en compression, ce qui est favorable pour respecter la limite élastique de la pièce 30. L'effort élastique emmagasiné dans les ailes 33,34 de la pièce 30 contribue à empêcher un desserrage de la vis par rotation intempestive (action exercée par la plage de tête 31 sur la tête 21) et à rattraper un jeu dû au fluage du conducteur C1, par déplacement de la plage de pression 32 relativement à la portée 24 de la vis, avec une amplitude pouvant atteindre c . When tightening a conductor C1, for example, the rotation of the screw causes, by cooperation of its thread with the threaded orifice 12b, the rise of the cage 12 to its abutment against the underside of the fixed conductive branch 11 as well as the lowering of the screw relative to the cage 12, and to the housing 10. This descent is carried out as far as the stop of the lower area of the pressure range 32 against the opposite face of the branch 11. continuing the rotation of the screw then causes the compressive stress of the pressure piece 30, which results in the reduction of the concavity of the wings 33,34 and the application of the span 24 of the screw against the face internal 32a of the pressure range 32 (situation indicated in indents on the left part of Figure 4). It should be noted that the screw head urges the head range in compression, which is favorable to respect the elastic limit of the part 30. The elastic force stored in the wings 33,34 of the part 30 helps to prevent a loosening the screw by inadvertent rotation (action exerted by the head region 31 on the head 21) and catching a clearance due to the creep of the driver C1, by moving the pressure range 32 relative to the span 24 of the screw, with an amplitude up to c .
