Description

Domaine techniqueTechnical area

La présente invention concerne des mécanismes de connexion des prises de courant et plus précisément des bornes de connexion automatiques, en proposant une borne d'une grande simplicité de construction qui confère une grande fonctionnalité au système grâce à la rapidité de connexion et de déconnexion des conducteurs électriques sur les prises de courant.The present invention relates to connection mechanisms plugs and specifically automatic connection terminals, providing a terminal of great simplicity of construction that gives great functionality to the system through the speed of connection and disconnection of drivers electrical outlets.

Etat de la techniqueState of the art

Traditionnellement, la fixation de conducteurs électriques sur les bornes de connexion des dispositifs électriques s'effectue à l'aide de bornes à vis, lesquelles consistent en une lame métallique élastique faisant fonction de contact électrique et intégrant une vis avec écrou et rondelle ou tout élément similaire pour réaliser la fixation du câble, permettant ainsi d'établir la continuité de la transmission électrique.Traditionally, the fixing of electrical conductors on the connection terminals of the electrical devices is carried out using screw terminals, which consist of an elastic metal blade acting as an electrical contact and incorporating a screw with nut and washer or any element similar to achieve the fixing of the cable, thus establishing the continuity of the electrical transmission.

Actuellement, il existe aussi des systèmes de fixation des conducteurs électriques sans vis, cette dernière étant remplacée par des éléments de pression qui permettent de maintenir le câble et d'assurer la connexion correspondante, ce qui facilite substantiellement le travail de l'électricien, comme le montrent les solutions décrites dans le brevet européen EP 0 246 199 , le modèle d'utilité allemand DE 852 32 63 et les brevets américains US 2 731 668 , US 3 152 851 , US 4 759 726 , US 5 915 991 , US 6 666 707 et US 6 962 512 .Currently, there are also fastening systems of electrical conductors without screws, the latter being replaced by pressure elements that maintain the cable and ensure the corresponding connection, which substantially facilitates the work of the electrician, such as show the solutions described in the European patent EP 0 246 199 , the German utility model DE 852 32 63 and US patents US 2,731,668 , US 3,152,851 , US 4,759,726 , US 5,915,991 , US 6,666,707 and US 6,962,512 .

Parmi les différents systèmes connus qui ont été développés pour la fixation des câbles sans vis, il existe des systèmes dont l'élément de pression est configuré à la manière d'un bouton-poussoir ou d'un levier, ce dernier pouvant être solidaire de la lame métallique élastique ou basculant par rapport à des pivots de ce même levier ou du point de fixation de celui-ci.Among the various known systems that have been developed for fastening cables without screws, there are systems whose pressure element is configured in the manner of a push-button or a lever, the latter being able to be secured to the metal blade elastic or rocking relative to the pivots of the same lever or the attachment point thereof.

En ce sens, nous connaissons les solutions proposées par les brevets EP 1 605 547 de SIMON et EP 1 622 224 de LEGRAND. In this sense, we know the solutions proposed by patents EP 1 605 547 to SIMON and EP 1 622 224 to LEGRAND.

Le brevet européen EP 1 605 547 de SIMON décrit un mécanisme de connexion et de déconnexion rapide des bornes pour dispositifs électriques, caractérisé par le positionnement, à l'intérieur du corps de contact, d'un ressort de contact divisé en deux parties, ledit ressort possédant deux languettes pliées vers l'intérieur. Les extrémités angulaires inférieures des boutons d'actionnement, introduits par la partie supérieure du corps, s'appuient sur ces languettes, de telle sorte que ces languettes se balancent lorsqu'il est fait pression sur le bouton correspondant, provoquant la descente de la languette jusqu'à ce que l'extrémité du bouton s'emboîte dans un évasement transversal à section semi cylindrique que possède la languette pour son enclenchement, créant ainsi un espace suffisant pour placer l'extrémité du conducteur électrique, quel que soit son diamètre, lequel reste fixé quand la languette est déverrouillée pour retourner à sa position initiale.The European patent EP 1 605 547 to SIMON discloses a mechanism for fast connection and disconnection of terminals for electrical devices, characterized by positioning, within the contact body, a contact spring divided into two parts, said spring having two tabs folded inwards . The lower angular ends of the actuating buttons, introduced by the upper part of the body, rest on these tongues, so that these tabs swing when the corresponding button is pressed, causing the tab to descend. until the end of the button engages in a transverse flare with semi-cylindrical section that the tongue has for its engagement, thus creating a space sufficient to place the end of the electrical conductor, whatever its diameter, which remains fixed when the tongue is unlocked to return to its original position.

Pour sa part, le brevet européen EP 1 622 224 de LEGRAND décrit un dispositif électrique qui possède une carcasse isolante et une borne automatique insérée dans celle-ci, la borne étant formée d'un boîtier rigide qui présente une embase au niveau de la rainure de la carcasse grâce à laquelle est inséré le conducteur, et d'un élément flexible, constitué d'une lame élastique qui détermine une arête faisant face à l'embase de la carcasse. Par ailleurs, le boîtier rigide de la borne dispose d'une fenêtre à travers laquelle est inséré un levier qui permet la connexion ou la déconnexion de l'élément conducteur qui se trouve entre l'embase et l'arête de la lame élastique.For its part, the European patent EP 1 622 224 to LEGRAND discloses an electrical device which has an insulating casing and an automatic terminal inserted therein, the terminal being formed of a rigid casing which has a base at the groove of the casing through which the conductor is inserted, and a flexible element, consisting of an elastic blade which determines an edge facing the base of the carcass. Furthermore, the rigid housing of the terminal has a window through which is inserted a lever which allows the connection or disconnection of the conductive element which is between the base and the edge of the elastic blade.

Ces solutions présentent la caractéristique commune d'actionner la borne automatiquement par un levier ou bouton de commande qui traverse une carcasse de contact pour faire pression sur un contact élastique, en utilisant pour cela une configuration structurelle complexe composée de pièces de taille réduite, ce qui représente un grand inconvénient au niveau de la fabrication.These solutions have the common feature of actuating the terminal automatically by a lever or control button which passes through a contact carcass to pressure an elastic contact, using for this a complex structural configuration composed of small parts, which represents a great disadvantage at the level of manufacture.

D'autres examples connus de mécanismes de connexion sont divulgués dans les demandes de brevet européen EP 0 908 965 A1 et EP 1 081 790 A2 .Other known examples of connection mechanisms are disclosed in European patent applications EP 0 908 965 A1 and EP 1 081 790 A2 .

Objet de l'inventionObject of the invention

L'invention a pour objet un dispositif électrique comprenant une borne de connexion automatique tel que défini dans la revendication 1.The subject of the invention is an electrical device comprising an automatic connection terminal as defined in claim 1.

Selon la présente invention, il est proposé une borne de connexion automatique, laquelle, grâce à ses caractéristiques de construction, présente une simplicité structurelle qui la rend avantageusement fonctionnelle par rapport aux solutions traditionnelles déjà connues, tout en réduisant les coûts de production.According to the present invention, there is provided an automatic connection terminal, which, due to its construction features, has a structural simplicity that makes it advantageously functional compared to traditional solutions already known, while reducing production costs.

La borne de connexion automatique objet de l'invention s'applique à un dispositif électrique comme, par exemple, une prise de courant constituée d'une base, d'une carcasse et d'une plaque intermédiaire, la borne de connexion automatique étant elle-même constituée d'un levier de commande, d'une borne de câblage et d'un feuillard métallique. La borne de câblage et le feuillard sont couplés entre eux de sorte que des languettes supérieures du feuillard obstruent les conduits de guidage du câblage.The automatic connection terminal object of the invention applies to an electrical device such as, for example, a socket consisting of a base, a carcass and an intermediate plate, the automatic connection terminal being it. -Even consists of a control lever, a wiring terminal and a metal strip. The wiring terminal and the strip are coupled together so that upper tabs of the strip obstruct the wiring guide ducts.

L'ensemble borne-feuillard est inséré dans la base, recouvert par une plaque intermédiaire et enfermé dans un logement qui est doté d'ouvertures par lesquelles est introduit le levier de commande, lequel est libre et s'appuie sur le feuillard.The terminal strip-strip is inserted into the base, covered by an intermediate plate and enclosed in a housing which is provided with openings through which is introduced the control lever, which is free and rests on the strip.

Quand le levier est actionné, son extrémité finale fait pression sur le feuillard métallique, libérant le passage des câbles à travers les conduits de guidage des câbles, de manière à ce que les câbles puissent être introduits par lesdits conduits, et quand le levier ne fait plus pression, le feuillard retourne à sa position initiale, en appuyant sur les câbles de manière à ce que ceux-ci soient maintenus.When the lever is actuated, its end end presses on the metal strip, freeing the passage of the cables through the cable guide ducts, so that the cables can be introduced through said conduits, and when the lever does not more pressure, the strip returns to its initial position, pressing the cables so that they are maintained.

Description détaillée de l'inventionDetailed description of the invention

L'objet de la présente invention se réfère à une borne de connexion automatique, pour une application à tout type de dispositif électrique, qui présente des caractéristiques de construction et des caractéristiques fonctionnelles très avantageuses.The object of the present invention refers to an automatic connection terminal, for application to any type of electrical device, which has very advantageous construction characteristics and functional characteristics.

La figure 1 représente un exemple d'application de la borne de connexion automatique (1) objet de l'invention, sur une prise de courant (2) conventionnelle, application sur laquelle la présente description va se baser à titre d'exemple, mais sans caractère limitatif.The figure 1 represents an example of application of the automatic connection terminal (1) object of the invention, on a conventional socket (2), application on which the present description will be based as an example, but without limitation .

La prise de courant (2) sur laquelle est appliquée la borne (1) de l'invention est constituée d'une pièce de base (3), d'une plaque intermédiaire (4) et d'une carcasse (5) qui sont assemblées entre elles par clipsage.The socket (2) to which the terminal (1) of the invention is applied consists of a base piece (3), an intermediate plate (4) and a carcass (5) which are assembled together by clipping.

La pièce de base (3) possède à ses extrémités des logements (6) pour insérer à l'intérieur les bornes de connexion (1), tandis que la carcasse (5) possède sur l'extrémité de ses bords des rainurages (7) pour l'insertion des leviers de commande (8) des bornes (1) objet de l'invention (voir figures 2, 3 et 4).The base part (3) has at its ends housings (6) to insert the connection terminals (1) inside, whereas the carcass (5) has grooves (7) on the end of its edges (7). for the insertion of the control levers (8) of the terminals (1) which is the subject of the invention (see figures 2 , 3 and 4 ).

La borne de connexion automatique (1) se compose, pour sa part, d'une zone de connexion constituée d'une pièce enveloppante (9) métallique, à l'intérieur de laquelle est logé et assemblé un feuillard élastique (10), également métallique (voir figure 5).The automatic connection terminal (1) consists, for its part, of a connection zone consisting of a wrapping piece (9) metal, inside which is housed and assembled an elastic strip (10), also metallic (see figure 5 ).

La pièce enveloppante (9) définit des conduits (11) en forme de cylindres qui permettent de réaliser le guidage et l'emprisonnement des conducteurs électriques à connecter, en laissant, entre lesdits conduits (11), une ouverture (12) grâce à laquelle le feuillard élastique (10) reste découvert.The enveloping part (9) defines cylindrical ducts (11) which make it possible to guiding and imprisoning the electrical conductors to be connected, leaving, between said ducts (11), an opening (12) through which the elastic strip (10) remains uncovered.

Le feuillard élastique (10) présente approximativement une forme en "U", l'une de ses branches étant plus longue que l'autre, et la branche la plus petite présentant une saillie centrale (10.1) vers la partie intérieure du "U" et, sur les côtés, des saillies (10.2) vers la partie extérieure.The elastic strip (10) has approximately a "U" shape, one of its branches being longer than the other, and the smaller branch having a central projection (10.1) towards the inner part of the "U" and, on the sides, protrusions (10.2) towards the outer part.

Ces deux dernières saillies (10.2) obstruent l'accès aux conduits (11), empêchant l'entrée des conducteurs électriques depuis l'extérieur quand la borne de connexion (1) n'est pas en fonctionnement, comme représenté sur les figures 6 et 7.These last two protrusions (10.2) obstruct access to the conduits (11), preventing the entry of the electrical conductors from the outside when the connection terminal (1) is not in operation, as shown in the figures 6 and 7 .

Dans cette position, quand la borne de connexion (1) n'est pas opérationnelle, le levier (8) de commande, qui est fixé à la carcasse (5) de la prise de courant (2), n'agit pas sur les éléments (9 et 10) de la borne de connexion, rendant libre le positionnement de ceux-ci (voir figures 9, 12 et 15).In this position, when the connection terminal (1) is not operational, the control lever (8), which is fixed to the frame (5) of the socket (2), does not act on the elements (9 and 10) of the connection terminal, making the positioning of these terminals free (see figures 9 , 12 and 15 ).

Le levier de commande (8) détermine une surface de contact (I) entre sa partie frontale (8.1) et un palier (5.1) de la carcasse (5), tandis qu'un point de contact (II) est établi entre la base (8.2) de la manette du levier (8) et une zone courbe (5.2) de la carcasse (5) ; un troisième point de contact (III) étant en outre établi entre l'axe pivotant (8.3) du levier (8) et la partie interne (5.3) de la carcasse (5), comme représenté sur les figures 10, 13 et 16.The control lever (8) determines a contact surface (I) between its front portion (8.1) and a bearing (5.1) of the carcass (5), while a point of contact (II) is established between the base (8.2) the lever handle (8) and a curved area (5.2) of the carcass (5); a third point of contact (III) being furthermore established between the pivoting axis (8.3) of the lever (8) and the inner part (5.3) of the carcass (5), as shown on the figures 10 , 13 and 16 .

Quand la borne de connexion (1) est en fonctionnement, le levier de commande (8) est en contact, grâce à l'ouverture (12) située entre les conduits de guidage (11), avec le feuillard (10), sur un point de contact (IV), en déformant ledit feuillard (10) proportionnellement à la pression exercée sur la manette du levier (8), comme représenté sur les figures 9, 12 et 15.When the connection terminal (1) is in operation, the control lever (8) is in contact, thanks to the opening (12) situated between the guide ducts (11), with the strip (10), on a point of contact (IV), by deforming said strip (10) in proportion to the pressure exerted on the handle of the lever (8), as shown in FIGS. figures 9 , 12 and 15 .

Dans cette position opérationnelle dans laquelle l'extrémité (8.4) du levier (8) entre en contact avec le feuillard (10) en le déformant, une pression négative se crée et fait en sorte que le levier (8) tend à monter, mettant alors en contact l'axe pivotant (8.3) du levier (8) avec la partie interne (5.3) de la carcasse (5), sur une surface de contact (V), selon les figures 11, 14 et 17, de telle sorte que le basculement du levier (8), dans ces conditions, fasse en sorte que l'extrémité (8.4) de celui-ci exerce une contrainte sur le feuillard (10), ce qui fait en sorte que les saillies (10.2) cessent d'obturer le passage par les contacts (11), en permettant l'introduction des câbles électriques à connecter, par lesdits conduits (11), dans lesquels ils sont emprisonnés par les saillies (10.2) en l'absence d'action du levier (8), la fixation et la connexion des câbles dans la borne (1) étant ainsi établies.In this operational position in which the end (8.4) of the lever (8) comes into contact with the strip (10) by deforming it, a negative pressure is created and makes the lever (8) tend to rise, putting then in contact with the pivoting axis (8.3) of the lever (8) with the internal part (5.3) of the carcass (5), on a contact surface (V), according to the figures 11 , 14 and 17 , so that the tilting of the lever (8), under these conditions, causes the end (8.4) thereof to exert stress on the strip (10), so that the projections ( 10.2) stop closing the passage through the contacts (11), allowing the introduction of the electrical cables to be connected, by said conduits (11), in which they are trapped by the projections (10.2) in the absence of action of the lever (8), the fixing and the connection of the cables in the terminal (1) being thus established.
