Description

Le présent mémoire descriptif traite d'un "relais perfectionné".This specification describes a "sophisticated relay".

On constate un accroissement constant de la prolifération des automatismes pour la commande électrique de tous types de mécanismes, dans le fonctionnement desquels les relais sont parmi les dispositifs utilisés le plus à profusion, ceci en raison de la grande quantité d'opérations fonctionnelles qu'on peut réaliser avec eux.There is a constant increase in the proliferation of automatisms for the electrical control of all types of mechanisms, in the of which relays are among the most widely used devices profusion, this due to the large amount of functional operations that can perform with them.

Lesdits dispositifs consistent en principe en un électro-aimant et une pièce métallique capable d'être mise en mouvement sous la commande de ce dernier entre deux ou plus de deux positions pour l'accomplissement d'une fonction concrète déterminée quelconque qui peut être, par exemple, la fermeture et l'ouverture d'un conduit, etc..Said devices consist in principle of an electromagnet and a metal part capable of being moved under the control of this last between two or more positions for the performance of a function any definite concrete which can be, for example, closure and opening a duct, etc.

EP-A-0 369 111 décrit un relais constitué par une carcasse contenante munie d'un socle de fermeture, cependant qu'il est prévu à l'intérieur un mécanisme formé d'un électro-aimant et d'une pièce mobile qui est disposée en montage basculant sur un support correspondant, la partie centrale de la pièce mobile s'appuyant sur le support. La partie centrale d'un ressort plat en forme de "U" soutien la pièce mobile au niveau de l'extrémité de celle-ci qui est éloignée de l'électro-aimant, tandis que les extrémités du ressort plat sont à leur tour soutenues par une barre prévue sur ledit support. Un ressort hélicoïdal disposé dans la direction verticale est connecté à la pièce basculante au niveau de l'extrémité de celle-ci qui est soutenue par le ressort plat, afin d'appliquer à cette pièce une force destinée à interrompre le contact entre elle et l'électro-aimant.EP-A-0 369 111 describes a relay constituted by a containing carcass provided with a closing base, however a mechanism is provided inside formed of an electromagnet and a moving part which is arranged in assembly tilting on a corresponding support, the central part of the moving part leaning on the support. The central part of a flat "U" shaped spring supports the moving part at the end thereof which is distant from the electromagnet, while the ends of the flat spring are in turn supported by a bar provided on said support. A coil spring arranged in the vertical direction is connected to the tilting piece at the end of which is supported by the flat spring, in order to apply a force to this part intended to interrupt the contact between it and the electromagnet.

Dans ces fonctions d'application des relais, une caractéristique fondamentale est généralement la précision fonctionnelle et, dans ce sens, on développe continuellement de nouvelles réalisations, en tentant de la combiner en outre avec la simplicité de la construction qui, dans de nombreux cas, doit aussi être compatible avec des dimensions très réduites.In these relay application functions, a characteristic fundamental is generally the functional precision and, in this sense, we continually develops new creations, trying to combine it with besides with the simplicity of construction which in many cases must also be compatible with very small dimensions.

Dans ce sens de progression, selon la présente invention, on propose un nouveau relais qui a été perfectionné, dans ses caractéristiques constructives et fonctionnelles, de manière à obtenir une réalisation très avantageuse relativement à celles des dispositifs similaires connus jusqu'à ce jour.In this sense of progression, according to the present invention, a new relay which has been perfected, in its constructive characteristics and functional, so as to obtain a very advantageous embodiment relative to those of similar devices known to date.

La présente invention prévoit un relais constitué par une carcasse contenante munie d'un socle de fermeture et de moyens servant à la fixation au lieu d'application, cependant qu'il est prévu à l'intérieur un mécanisme formé d'un électroaimant et d'une pièce mobile qui est disposée en montage basculant sur un support correspondant, caractérisé en ce que la pièce mobile est disposée sur le support par emboítement dans ce dernier par des tourillons latéraux qui jouent le rôle d'axes de rotation, ladite pièce étant attirée à l'arrière, où elle forme une extrémité repliée vers le haut en forme de "U", au moyen d'un ressort incorporé entre le bord libre de la configuration extrême mentionnée et le support de montage.The present invention provides a relay constituted by a carcass container provided with a closing base and means used for fixing to the place application, however that there is provided inside a mechanism formed of a electromagnet and a moving part which is arranged in tilting mounting on a corresponding support, characterized in that the moving part is arranged on the support by fitting into the latter by lateral pins which play the role of axes of rotation, said part being drawn to the rear, where it forms a end folded upwards in a "U" shape, by means of a built-in spring between the free edge of the mentioned extreme configuration and the support mounting.

Avec tout ceci, on obtient un ensemble structurel extrêmement simple, à base d'un nombre minime d'éléments constitutifs, dont la simplicité autorise une grande facilité de construction et de montage, en donnant lieu à un ensemble fonctionnel qui se distingue par une absence totale de complexités, avec pour résultat une absolue efficacité de fonctionnement avec une grande précision.With all this, we obtain an extremely simple structural assembly, base of a minimal number of constituent elements, whose simplicity allows a great ease of construction and assembly, giving rise to a set functional which is distinguished by a total absence of complexities, with for result absolute operating efficiency with high precision.

Au total, ce relais préconisé possède certainement des caractéristiques très avantageuses qui confèrent à sa réalisation une vie propre par elle-même et un caractère préférable par rapport aux relais classiques.All in all, this recommended relay certainly has very benefits that give its realization a life of its own and a preferable compared to conventional relays.

    • L'objet de l'invention consiste en un relais du type de ceux qu'on utilise comme dispositif fonctionnel pour la réalisation de diverses fonctions de contrôle et de commande dans des installations électriques, ledit relais étant essentiellement constitué par un mécanisme fonctionnel qui se trouve logé à l'intérieur d'une carcasse (1), laquelle, selon un exemple de réalisation, est fermée au moyen d'un socle (2) qui se fixe par emboítement d'ergots latéraux (3) dans des orifices correspondants (4) de la carcasse (1) cependant que cette dernière est à son tour munie de formations (5) pour la fixation, par vissage ou autres moyens analogues quelconques, sur le lieu d'application.The object of the invention consists of a relay of the type of those that we use as a functional device for realization of various control and command functions in electrical installations, said relay being essentially constituted by a functional mechanism which is housed inside a carcass (1) which, according to an embodiment, is closed by means of a base (2) which is fixed by fitting lateral pins (3) in corresponding holes (4) of the carcass (1) while the latter is in turn provided with formations (5) for the fixing, by screwing or any other similar means, at the place of application.

    Le mécanisme fonctionnel se compose, de son côté, d'une façon classique, d'un électro-aimant (6) et d'une pièce mobile (7) pouvant être commandée par celui-ci mais, de façon particulière, ladite pièce mobile (7) étant disposée selon un montage basculant, montée sur un support (8) respectif par rapport auquel elle est en outre attirée au niveau de sa partie arrière par un ressort (9) qui tend à la maintenir écartée de l'électro-aimant (6) ainsi qu'on peut le voir sur la figure 2.The functional mechanism, for its part, consists of a classic way, an electromagnet (6) and a part mobile (7) can be controlled by it but, so particular, said movable part (7) being arranged in a tilting mounting, mounted on a respective support (8) by relationship to which it is also attracted in terms of its rear part by a spring (9) which tends to hold it away from the electromagnet (6) as can be seen on Figure 2.

    Ledit mécanisme comprend en outre une pièce de base (10) qui, de même que la carcasse (1), le socle (2) et le support (8), est faite d'une matière synthétique isolante, cette pièce de base (10) formant un corps plat en forme de plaque, sur lequel s'élève une formation solidaire (11) qui constitue le corps de bobine pour le bobinage de la bobine correspondante (12) de l'électro-aimant (6).The mechanism further includes a base piece (10) which, like the carcass (1), the base (2) and the support (8), is made of an insulating synthetic material, this base part (10) forming a flat body in the form of a plate, on which rises a solidarity formation (11) which constitutes the reel body for winding the reel corresponding (12) of the electromagnet (6).

    Le noyau de l'électro-aimant (6) mentionné est constitué à son tour par une pièce métallique (13) en forme de "U", laquelle s'emboíte axialement par une de ses branches à travers le corps de bobine (11), en formant le noyau proprement dit, tandis que l'autre branche passe à travers une ouverture respective (14) du corps plat de la pièce (10), en s'emboítant de l'autre côté dans un logement (21) défini par le support (8) de la pièce basculante (7), de sorte qu'ainsi, au moyen de ladite pièce (13) qui constitue le noyau, on établit à la fois la fixation du support (8) mentionné et la formation du noyau fonctionnel de l'électroaimant (6) mentionné ; la pièce (13) mentionnée se disposant en appui sur un aimant permanent (22) qui se trouve logé dans le socle (2).The core of the mentioned electromagnet (6) consists in turn by a metal part (13) in the shape of a "U", which fits axially by one of its branches to through the coil body (11), forming the core proper, while the other branch goes through a respective opening (14) of the flat body of the part (10), by fitting on the other side into a defined housing (21) by the support (8) of the tilting part (7), so that thus, by means of said part (13) which constitutes the core, both fixing the support (8) mentioned and the formation of the functional core of the electromagnet (6) mentioned; the part (13) mentioned disposing supported by a permanent magnet (22) which is housed in the base (2).

    Selon une forme préférée de réalisation, la pièce basculante (7) mentionnée est constituée par une plaquette métallique (15) en forme de palette et une pièce porteuse (16) en forme de "U", les deux étant réunies par fixation solidaire par matage, soudure par points ou n'importe quelle autre forme classique, ladite pièce porteuse (16) définissant une petite formation (17) dans sa partie supérieure, pour l'accrochage du ressort (9) dans la tension de celui-ci par rapport à une autre formation d'accrochage réciproque (18) définie dans le support (8) ; tandis que, latéralement, cette pièce (16) forme de petits tourillons (19) qui servent d'axes de basculement pour le montage sur le support (8), en ce sens que ces derniers s'emboítent dans des encoches de logement correspondantes (20).According to a preferred embodiment, the part tilting (7) mentioned is constituted by a plate metallic (15) in the form of a pallet and a supporting part (16) in the shape of a "U", the two being joined by fixing secured by matting, spot welding or any another conventional form, said load-bearing part (16) defining a small formation (17) in its upper part, for the attachment of the spring (9) in the tension thereof by relation to another reciprocal attachment formation (18) defined in the support (8); while, laterally, this part (16) in the form of small pins (19) which serve as axes tilting for mounting on the support (8), in this direction that the latter fit into housing slots corresponding (20).

    Avec tout ceci, lorsque l'électro-aimant (6) se trouve désexcité, la pièce (7) reste basculée de telle manière que la palette (15) reste collée audit électro-aimant (6), en raison du flux magnétique établi dans la pièce de noyau (13) par l'aimant (22), ainsi qu'on peut le voir sur la figure 3.With all this, when the electromagnet (6) is de-energized, the part (7) remains tilted so that the pallet (15) remains bonded to said electromagnet (6), due to the magnetic flux established in the core part (13) by the magnet (22), as can be seen in Figure 3.

    Et, lorsqu'on excite l'électro-aimant (6), par alimentation de courant à la bobine (12), le flux magnétique que la pièce de noyau (13) acquiert s'oppose à celui créé par l'aimant (22) et a pour effet que la force magnétique exercée sur la palette (15) diminue, l'ensemble de la pièce (7) basculant en conséquence sous l'effet de la tension du ressort (9), jusqu'à une position telle que celle représentée sur la figure 2, à partir de laquelle le retour à la position antérieure de la figure 3 se produit lorsque le relais est de nouveau armé, par suite de l'actionnement d'un pivot (23) avec lequel il est possible de pousser la palette (15) vers le noyau (13) à l'encontre de la force du ressort (9).And, when the electromagnet (6) is excited, by current supply to the coil (12), the magnetic flux that the core piece (13) acquires is opposed to that created by the magnet (22) and has the effect that the magnetic force exerted on the pallet (15) decreases, the whole part (7) tilting accordingly under the effect of the tension of the spring (9), to a position such as that shown in Figure 2, from which the return to the position Figure 3 occurs when the relay is new armed, following the actuation of a pivot (23) with which it is possible to push the pallet (15) towards the core (13) against the force of the spring (9).

    Selon les figures 4, 5 et 6, on prévoit un exemple de réalisation d'une forme dans laquelle le socle (2) forme une paroi (24) d'emboítement dans la carcasse (1), cependant que, sur la partie extérieure de ladite paroi (24), font saillie des formations saillantes (25), lesquelles sont susceptibles de s'emboíter dans des fenêtres correspondantes (26) de la paroi de la carcasse (1), pour établir la fixation de la fermeture dans le montage ; tandis que la pièce de base (10), qui comporte le corps de bobine (11), forme à son tour dans ses côtés des formations (27) au moyen desquelles elle peut établir un encliquetage de fixation dans le montage, sur des fenêtres respectives (28) de la paroi (24) du socle (2), comme on peut le voir sur la figure 6, cette pièce (10) formant en outre des ailes horizontales saillantes (29) avec lesquelles elle prend appui sur le bord supérieur de la paroi (24) du socle (2), pour être à leur tour bloquées dans le montage par la carcasse (1), comme on peut le voir sur la figure 5, de sorte qu'on obtient un montage entièrement fixé de tout l'ensemble du relais ; en permettant de maintenir des distances fixes à l'intérieur de l'ensemble, de sorte qu'on obtient un positionnement exact et stable des éléments du mécanisme et l'obtention consécutive d'une grande précision du fonctionnement.According to Figures 4, 5 and 6, an example of production of a shape in which the base (2) forms a wall (24) nesting in the carcass (1), however, on the outer part of said wall (24), protrude protruding formations (25), which are susceptible to fit into corresponding windows (26) of the carcass wall (1), to establish the fixing of the closing in assembly; while the base part (10), which comprises the coil body (11), in turn forms in its sides of the formations (27) by means of which it can establish a fixing snap in the assembly, on respective windows (28) of the wall (24) of the base (2), as can be seen in figure 6, this part (10) further forming protruding horizontal wings (29) with which it rests on the upper edge of the wall (24) of the base (2), to be in turn blocked in the mounting by the carcass (1), as can be seen on the figure 5, so that a fully fixed assembly is obtained of the entire relay; by allowing to maintain fixed distances inside the assembly, so that obtains an exact and stable positioning of the elements of the mechanism and subsequent high accuracy of operation.

    La nature de la présente invention, ainsi que sa réalisation industrielle, étant suffisamment décrites, il faut seulement ajouter qu'il est possible d'introduire des changements de forme, de matière et de disposition dans son ensemble et dans ses parties constitutives, sans sortir du cadre de l'invention, pourvu que ces altérations ne sortent pas de son principe comme défini dans les revendications.The nature of the present invention, as well as its industrial realization, being sufficiently described, it only add that it is possible to introduce changes of form, material and arrangement in its together and in its constituent parts, without leaving the scope of the invention, provided that these alterations do not leave not its principle as defined in the claims.

Relay according to Claim 2, characterized in that the core of the electromagnet (6) is constituted by a metallic U-shaped piece (13) which is incorporated by axial insertion via one of its arms in the formation (11) which forms the body of the coil (12), while, with the other arm, it passes through the rectangular plate, being inserted on the other side in a housing (21) of the support (8) of the pivoting piece (7), securing of said support (8) thus being ensured by this same piece (13) of the core.
    4. Relay according to Claim 1, characterized in that the pivoting mobile piece (7) is constituted by a metal pallet (15) which is assembled rigidly, by caulking or the like, on a rear bearing piece (16) which forms the hooking of the tension spring (9), and the journals (19) for rotatable assembly on the support (8).
    5. Relay according to Claim 2, characterized in that the closure base (2) forms a wall (24) for fit in the recipient casing (1), said wall (24) of the base (2) and the very wall of the casing (1) forming respective reciprocal formations (25, 26) for a fixing clip for retention in the assembly; while the base piece (10) which bears the coil body (11) for the electromagnet (6) in turns forms, level with the mentioned wall (24) of the base (2), other reciprocal formations (27, 28) serving to fix a respective clip for retention in the assembly, which piece (10) which bears the coil body (11) further presents horizontal projecting flanges (29) by means of which this piece is in turn fixed by blocking between the casing (1) and the base (2), making it possible to maintain fixed distances within the assembly.
