Description

L'invention concerne une borne de raccordement d'un appareil d'installation électrique, comportant une cage pourvue d'une ouverture destinée à recevoir un conducteur, une plage de contact s'étendant dans ladite ouverture, destinée à être raccordée à un circuit électrique de l'appareil, et une vis de serrage montée dans la cage pour serrer la plage de contact contre le conducteur, la plage de contact comportant un évidement agencé en regard de l'extrémité de la vis, de sorte que l'extrémité de la vis puisse s'engager dans ledit évidement lors du serrage. Un tel dispositif est décrit par exemple par FR-A-1 566 270.The invention relates to a connection terminal of an installation device. electric, comprising a cage provided with an opening intended to receive a conductor, a contact pad extending in said opening, intended to be connected to a electrical circuit of the device, and a clamping screw mounted in the cage to tighten the contact pad against the conductor, the contact pad comprising a recess arranged opposite the end of the screw, so that the end of the screw can engage in said recess during tightening. Such a device is described for example by FR-A-1 566 270.

Un appareil d'installation électrique doit pouvoir être raccordé électriquement à l'aide de conducteurs rigides ou souples de diamètres très divers. Cette exigence provient soit de la pratique d'installation, soit des normes nationales et internationales.An electrical installation device must be capable of being electrically connected to using rigid or flexible conductors of very different diameters. This requirement comes either from installation practice or from national standards and international.

Pour assurer ce raccordement, l'appareil comporte souvent des bornes associées à des plages de contact destinées à alimenter les différentes fonctions de l'appareil; ces bornes et plages de contact sont localisées dans l'appareil généralement par montage sur un boítier isolant. Lorsqu'il procède au raccordement, l'opérateur agit généralement sur une vis à l'aide d'un tournevis manuel ou motorisé et exerce donc des efforts mécaniques sur l'appareil.To ensure this connection, the device often has terminals associated with contact pads intended to supply the various functions of the device; these terminals and contact pads are located in the device generally by mounting on an insulating box. When connecting, the operator acts usually on a screw using a manual or motorized screwdriver and therefore exercises mechanical forces on the device.

Vu la diversité des types de conducteurs qui doivent pouvoir être raccordés, les plages de contact doivent être dimensionnées pour les gros conducteurs et lorsqu'on veut serrer un conducteur de petit diamètre, celui-ci peut se mettre indifféremment à gauche, au milieu ou à droite de l'espace libre ou dans toute autre position intermédiaire. Ces positions du conducteur amènent des répartitions d'efforts qui ne sont pas favorables à une bonne tenue mécanique des constituants et qui provoquent des déplacements relatifs entre la plage de contact et la cage de la borne, comme on le décrira en détail plus loin. Ces déplacements créent des efforts parasites dans le boítier.Given the variety of types of conductors that must be able to be connected, the contact pads must be sized for large conductors and when wants to clamp a small diameter conductor, it can be indifferently left, middle or right of the free space or in any other position intermediate. These driver positions lead to load distributions which do not are not favorable to good mechanical strength of the constituents and which cause relative displacements between the contact pad and the terminal cage, as we will describe it in detail later. These displacements create parasitic forces in the housing.

Les boítiers, généralement en matières plastiques, sont soumis à des efforts anormaux qui peuvent provoquer leur rupture ou des déformations inacceptables. Pour des raisons d'encombrement, ces boítiers ne peuvent pas être renforcés outre mesure.The housings, generally made of plastic, are subjected to efforts abnormal which can cause rupture or unacceptable deformation. For reasons of space, these boxes cannot be reinforced in addition measured.

La présente invention vise à éviter les problèmes évoqués ci-dessus, en empêchant un déplacement relatif susceptible de créer des efforts parasites entre la cage de la borne, la plage de contact et le boítier ou une autre structure supportant la borne.The present invention aims to avoid the problems mentioned above, by preventing a relative displacement capable of creating parasitic forces between the cage of the terminal, the contact pad and the housing or other structure supporting the terminal.

La borne de raccordement selon l'invention est caractérisée en ce que ledit évidement est formé par un lamage ménagé dans un élément de renfort fixé sur la plage de contact.The connection terminal according to the invention is characterized in that said recess is formed by a countersink formed in a reinforcing element fixed on the contact range.

Ainsi, dès le début du serrage, la plage de contact est retenue longitudinalement et transversalement par la vis engagée dans l'évidement correspondant. En conséquence, même si la pression de serrage s'exerce surtout près d'un bord de l'extrémité de la vis parce que le conducteur est décalé de ce côté-là, la poussée longitudinale qui en résulte est absorbée dans l'évidement lui-même et ne se transmet donc pas à l'extérieur de la borne. La plage de contact ne peut pratiquement pas se déplacer longitudinalement par rapport à la cage.Thus, from the start of tightening, the contact area is retained longitudinally and transversely by the screw engaged in the corresponding recess. In consequence, even if the clamping pressure is exerted mainly near an edge of the end of the screw because the conductor is offset on that side, the thrust resulting longitudinal is absorbed in the recess itself and does not therefore not transmitting outside the terminal. The contact area cannot practically not move longitudinally relative to the cage.

De préférence, l'évidement est cylindrique et peut avoir un diamètre sensiblement égal au diamètre de l'extrémité de la vis. Dans une autre exécution, le logement peut être conique ou tronconique. Preferably, the recess is cylindrical and can have a diameter substantially equal to the diameter of the end of the screw. In another embodiment, the housing can be conical or frustoconical.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description suivante d'un exemple de réalisation donné à titre d'exemple non limitatif et en référence au dessin annexé, dans lequel :

  • la figure 1 est une vue en bout d'une borne selon l'art antérieur, dans laquelle un conducteur cylindrique est bloqué dans une position décentrée,
  • la figure 2 est une vue en coupe axiale suivant la ligne II-II de la figure 1,
  • la figure 3 représente une forme de réalisation d'une borne selon l'invention suivant une vue en bout analogue à la figure 1,
  • la figure 4 est une vue en coupe axiale suivant la ligne IV-IV de la figure 3,
  • la figure 5 est une vue agrandie du détail V de la figure 4, et
  • la figure 6 est une vue en perspective d'un élément de renfort incorporé à la borne selon l'invention.
    • Other characteristics and advantages of the present invention will emerge from the following description of an exemplary embodiment given by way of nonlimiting example and with reference to the appended drawing, in which:
  • FIG. 1 is an end view of a terminal according to the prior art, in which a cylindrical conductor is blocked in an off-center position,
  • FIG. 2 is a view in axial section along the line II-II of FIG. 1,
  • FIG. 3 represents an embodiment of a terminal according to the invention in an end view similar to FIG. 1,
  • FIG. 4 is a view in axial section along the line IV-IV of FIG. 3,
  • FIG. 5 is an enlarged view of detail V of FIG. 4, and
  • Figure 6 is a perspective view of a reinforcing element incorporated in the terminal according to the invention.

    • Les figures 1 et 2 représentent une borne de raccordement 1 selon l'art antérieur, comportant une cage métallique 2 traversée longitudinalement par une ouverture 3 et pourvue d'une patte inférieure 4 en forme de bavette empêchant l'introduction erronée du câble sous la borne lors du vissage. Une vis de serrage 5 ayant une partie filetée 6 est engagée dans un alésage taraudé 7 de la cage 2 et présente une extrémité cylindrique 8 à l'intérieur de l'ouverture 3, où cette extrémité 8 est destinée à presser ensemble un conducteur 9, une plage de contact 10 et un élément de renfort 11 fixé sur la plage 10 et appelé "renfort de plage". La plage de contact 10 est formée par l'extrémité d'une lamelle conductrice s'étendant à l'intérieur de l'appareil et fixée directement ou indirectement au boítier. Le conducteur 9 est destiné à raccorder électriquement la plage de contact 10 à un circuit extérieur à l'appareil.FIGS. 1 and 2 represent a connection terminal 1 according to the prior art, comprising a metal cage 2 traversed longitudinally by an opening 3 and provided with a lower flap 4 in the form of a bib preventing the introduction wrong cable under the terminal when screwing. A clamping screw 5 having a part threaded 6 is engaged in a threaded bore 7 of the cage 2 and has a cylindrical end 8 inside the opening 3, where this end 8 is intended to press together a conductor 9, a contact pad 10 and an element reinforcement 11 fixed on the pad 10 and called "beach pad". The contact range 10 is formed by the end of a conductive strip extending inside of the device and fixed directly or indirectly to the housing. Driver 9 is intended to electrically connect the contact pad 10 to an external circuit to the device.

    Comme le montre la figure 1, le conducteur 9 est généralement décalé latéralement par rapport à l'axe, de sorte que les éléments solidaires 10 et 11 ont tendance à s'incliner latéralement lors du serrage de la vis. Il en résulte que l'extrémité 8 de la vis exerce sa force axiale de serrage sur l'élément 11 essentiellement sur une surface d'application 13 qui est décalée latéralement par rapport à l'axe 12. Du fait de la rotation de la vis, cette surface 13 se déplace tangentiellement dans la direction longitudinale de l'ouverture 3, si bien qu'elle entraíne par friction l'élément de renfort 11 et la plage de contact 10 qui lui est liée. Ce phénomène tend à produire un déplacement longitudinal D1 de la cage 2 et/ou un déplacement longitudinal opposé D2 de la plage de contact 10, c'est-à-dire un déplacement relatif D entre ces deux éléments, qui par ailleurs sont généralement liés au boítier de l'appareil. C'est ainsi que le serrage de la vis 5 engendre les efforts parasites mentionnés dans l'introduction.As shown in Figure 1, the conductor 9 is generally offset laterally relative to the axis, so that the integral elements 10 and 11 tend to tilt sideways when tightening the screw. It follows that the end 8 of the screw exerts its axial tightening force on element 11 essentially on a surface 13 which is offset laterally with respect to the axis 12. Due to the rotation of the screw, this surface 13 moves tangentially in the direction longitudinal of the opening 3, so that it frictionally drives the element of reinforcement 11 and the contact pad 10 which is linked to it. This phenomenon tends to produce a longitudinal movement D1 of the cage 2 and / or a longitudinal movement opposite D2 of the contact pad 10, that is to say a relative displacement D between these two elements, which moreover are generally linked to the housing of the device. It is as well as tightening the screw 5 generates the parasitic forces mentioned in the introduction.

    Dans la forme de réalisation de l'invention représentée par les figures 3 à 5, la plupart des composants de la borne de raccordement 21 sont semblables à ceux de la borne 1 décrite plus haut, et c'est pourquoi ils portent les mêmes numéros de référence. C'est le cas notamment de la cage 2, de la vis 5 et de la plage de contact 10. Par contre, l'élément de renfort 22 est différent de l'élément 11, comme on peut le voir plus en détail dans les figures 5 et 6. La borne 21 est de préférence du type à cage mobile, c'est-à-dire que la cage 2 peut se déplacer dans la direction de la vis 5 quand on actionne la vis.In the embodiment of the invention shown in Figures 3 to 5, the most of the components of the connection terminal 21 are similar to those of the terminal 1 described above, and this is why they have the same reference. This is particularly the case for cage 2, screw 5 and the contact pad 10. On the other hand, the reinforcing element 22 is different from the element 11, as can be see it in more detail in Figures 5 and 6. Terminal 21 is preferably of the type movable cage, that is to say that the cage 2 can move in the direction of the screw 5 when you operate the screw.

    L'élément de renfort 22 est en acier trempé, et est conformé selon une plaquette généralement rectangulaire, fixée par exemple par sertissage ou soudage à la plage de contact 10. Dans la face supérieure de l'élément, un évidement cylindrique 23 est ménagé, par exemple par lamage ou estampage, et il est emboíté à frottement doux sur l'extrémité 8 de la vis 5. L'évidement 23 s'étend par exemple sur environ la moitié de l'épaisseur de l'élément 22. Par ailleurs, des cornes latérales 24 sont prévues aux extrémités des bords longitudinaux de l'élément 22, pour constituer des arrêts butant contre les bords verticaux 25 et 26 de la cage 2 si l'élément se déboíte accidentellement de la vis 5 avant que celle-ci soit serrée.The reinforcing element 22 is made of hardened steel, and is shaped according to a plate generally rectangular, fixed for example by crimping or welding to the beach contact 10. In the upper face of the element, a cylindrical recess 23 is formed, for example by countersinking or stamping, and it is fitted with gentle friction on the end 8 of the screw 5. The recess 23 extends for example over approximately the half the thickness of the element 22. Furthermore, lateral horns 24 are provided at the ends of the longitudinal edges of the element 22, to constitute stops abutting the vertical edges 25 and 26 of the cage 2 if the element dislodges accidentally screw 5 before it is tightened.

    La figure 5 montre particulièrement le fonctionnement du dispositif lors du serrage, où la vis 5 exerce une force de serrage F sous l'action du couple C que l'opérateur lui applique. L'extrémité 8 de la vis est engagée dans l'évidement 23 et applique la force F au fond de celui-ci. Comme le conducteur 9 est généralement décalé latéralement par rapport à l'axe 12 de la vis, la plage de contact 10 et son élément de renfort 22 tendent à s'incliner latéralement. En conséquence, la force F est appliquée presque uniquement dans une zone excentrée 27 où la friction tend à entraíner longitudinalement l'élément de renfort 22. Cependant, la paroi latérale de l'évidement cylindrique 23 bute contre la surface latérale cylindrique de l'extrémité 8 de la vis et empêche ainsi un déplacement relatif entre l'élément de renfort 22 et la cage 2. Par conséquent, la plage de contact 10 et le conducteur 9 ne se déplacent pas, et les efforts parasites qui pourraient en résulter sont évités.FIG. 5 shows in particular the operation of the device during tightening, where the screw 5 exerts a clamping force F under the action of the torque C that the operator applies to him. The end 8 of the screw is engaged in the recess 23 and applies the force F at the bottom of it. As conductor 9 is generally offset laterally with respect to the axis 12 of the screw, the contact pad 10 and its element reinforcement 22 tend to tilt laterally. Consequently, the force F is applied almost only in an eccentric area 27 where friction tends to drive the reinforcing element longitudinally 22. However, the side wall of the cylindrical recess 23 abuts against the cylindrical lateral surface of the end 8 of the screw and thus prevents relative movement between the reinforcing element 22 and the cage 2. Consequently, the contact pad 10 and the conductor 9 do not move not, and the parasitic efforts which could result therefrom are avoided.

    La présente invention n'est pas limitée à l'exemple de réalisation décrit ci-dessus, mais s'étend à toute modification ou variante évidente pour un homme du métier. En particulier la forme de l'évidement 23 et de l'extrémité 8 de la vis n'est pas nécessairement cylindrique et pourrait être par exemple conique ou autre. Si un élément de renfort n'est pas prévu, l'évidement est ménagé dans la plage de contact 10 proprement dite. Dans une autre variante, à la place de l'évidement 23, un logement pour l'extrémité de la vis pourrait être défini sur l'élément 22 par des parties protubérantes estampées ou repliées.The present invention is not limited to the embodiment described above, but extends to any modification or variant obvious to a person skilled in the art. In particular, the shape of the recess 23 and of the end 8 of the screw is not necessarily cylindrical and could for example be conical or other. If a reinforcing element is not provided, the recess is provided in the contact range 10 proper. In another variant, instead of the recess 23, a housing for the end of the screw could be defined on element 22 by protruding parts stamped or folded.

    Une telle borne est utilisable sur n'importe quel type d'appareil d'installation électrique. Elle peut être du type à cage fixe ou mobile.Such a terminal can be used on any type of installation device electric. It can be of the fixed or mobile cage type.
