Description

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

Chaque jour voit croítre la prolifération des automatismes pour la commande électrique de tous types de mécanismes, les relais étaient parmi les dispositifs utilisés le plus abondamment pour cette fonction, ceci en raison de la grande quantité d'opérations fonctionnelles qu'on peut réaliser avec eux.Every day sees the proliferation of automation for the electrical control of all types of mechanisms, the relays were among the most widely used devices for this function, due to the large amount of functional operations that can be performed with them.

Lesdits dispositifs consistent essentiellement en un électro-aimant et une pièce métallique capable de se déplacer sous la commande dudit électro-aimant entre deux ou plus de deux positions pour l'accomplissement de quelque fonction concrète déterminée qui peut être, par exemple, la fermeture et l'ouverture d'un conduit, d'un circuit électrique etc..Said devices consist essentially of an electromagnet and a metal part capable of moving under the control of said electromagnet between two or more than two positions for the performance of any function specific concrete which can be, for example, the closing and opening of a conduit, electrical circuit etc.

Dans ces fonctions d'application des relais, une caractéristique fondamentale est généralement la précision fonctionnelle et, dans ce sens, on développe sans cesse de nouvelles réalisations, en vue de combiner ladite caractéristique de précision avec la simplicité de la construction et, dans de nombreux cas, également avec des dimensions très réduites.In these relay application functions, a characteristic fundamental is generally the functional precision and, in this sense, we is constantly developing new creations, with a view to combining said characteristic of precision with the simplicity of construction and, in many cases, also with very small dimensions.

Le document EP-A-0 278 064 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 électroaimant et d'une pièce mobile qui est disposée en montage basculant sur un support correspondant. Ce support consiste en un ressort à lame porté par un collier entourant une partie d'une pièce en forme de "U" constituant le noyau de la bobine de l'électro-aimant. La pièce basculante repose sur le ressort à lame et elle est tirée vers l'arrière par un ressort hélicoïdal qui relie cette pièce basculante à une pièce de base du relais. Selon ce montage, la pièce basculante peut glisser sur le ressort à lame au cours de son déplacement, ce qui provoque des erreurs dans le positionnement de la pièce basculante et, donc, des variations dans les points de contact entre la pièce basculante et le pôle de l'électro-aimant. Il existe aussi un problème d'usure du ressort à lame du fait du frottement de celui-ci par la pièce basculante. The document EP-A-0 278 064 describes a relay constituted by a containing carcass fitted with a closing base, however it is intended to inside a mechanism formed by an electromagnet and a moving part which is arranged in tilting mounting on a corresponding support. This support consists in a leaf spring carried by a collar surrounding part of a shaped part of "U" constituting the core of the solenoid coil. The tilting piece rests on the leaf spring and is pulled back by a coil spring which connects this tilting part to a basic part of the relay. According to this arrangement, the tilting part can slide on the leaf spring during its movement, this which causes errors in the positioning of the tilting part and, therefore, variations in the contact points between the tilting part and the pole the electromagnet. There is also a problem with the wear of the leaf spring due to the friction thereof by the tilting part.

Conformément à l'objet de la présente invention, on propose un nouveau relais qui a été perfectionné, de manière à obtenir des caractéristiques constructives et fonctionnelles, qui rendent sa réalisation plus avantageuse que celle des dispositifs similaires connus jusqu'à maintenant.In accordance with the object of the present invention, a new relay which has been perfected, so as to obtain constructive characteristics and functional, which make it more advantageous than similar devices known so far.

Ce relais objet de l'invention est essentiellement constitué par une carcasse contenante munie d'un socle de fermeture qui se fixe à celle-ci au moyen d'encliquetages, cependant qu'il y a à l'intérieur un ensemble fonctionnel formé d'une pièce de base qui définit dans sa propre conformation le corps pour la bobine de l'électro-aimant, qui possède à son tour des formations pour une fixation encliquetée sur le socle, cependant que, sur ladite pièce de base, se trouve une petite pièce complémentaire sur laquelle s'incorpore, en montage basculant, la pièce métallique mobile pouvant être commandée par l'électro-aimant.This relay object of the invention is essentially constituted by a containing carcass provided with a closing base which is fixed to the latter by means interlocking, however there is a functional assembly inside a basic part which defines in its own conformation the body for the coil electromagnet, which in turn has formations for attachment snapped onto the base, however, on said base piece, there is a small complementary part on which is incorporated, in tilting mounting, the mobile metal part which can be controlled by the electromagnet.

Ladite pièce métallique basculante est disposée en montage basculante sur ladite pièce complémentaire dans laquelle elle s'emboíte par un axe transversal solidaire et elle est sollicitée vers un positionnement d'écartement par rapport à l'électro-aimant par un ressort tirant incorporé entre sa partie arrière et la pièce de base. Ce montage favorise l'emboítement de l'axe dans les logements de la pièce support du basculement et assure, ainsi, un positionnement constant des points de contact entre la pièce basculante et la pièce constituant le noyau de l'électro-aimant. La pièce support du basculement est à son tour fixée par rapport à la pièce de base même au moyen de l'élément qui définit le noyau de l'électro-aimant, lequel est composé d'une pièce en "U" qui est positionnée en appui sur un aimant permanent qui se loge dans le socle.Said tilting metal part is disposed in tilting mounting on said complementary part in which it fits by a transverse axis integral and it is urged towards a spacing positioning relative to the electromagnet by a pulling spring incorporated between its rear part and the part of based. This mounting promotes the nesting of the axis in the housing of the room tilting support and thus ensures constant positioning of the points of contact between the tilting part and the part constituting the core of the electromagnet. The tilting support part is in turn fixed relative to the part basic even by means of the element which defines the core of the electromagnet, which is made up of a U-shaped piece which is positioned in contact with a magnet permanent which fits in the base.

On obtient de cette façon un dispositif qui offre un ensemble structurel extrêmement simple, formé d'un nombre minime d'éléments constitutifs, dont la simplicité autorise une grande facilité de construction et de montage, en donnant cependant lieu à un ensemble fonctionnel qui se distingue par sa grande efficacité fonctionnelle et sa grande précision sans aucun type de complexité.In this way we obtain a device which offers a structural whole extremely simple, formed of a minimal number of constituent elements, the simplicity allows great ease of construction and assembly, giving however, a functional group which stands out for its high efficiency functional and high precision without any type of complexity.

Avec tout ceci, le relais objet de l'invention 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. With all this, the relay object of the invention certainly has very advantageous characteristics which confer to its realization a clean life by itself and a preferable character compared to conventional relays.

Et sur lesdits dessins :To better understand the nature of the invention, we represent on the annexed drawings, by way of purely illustrative and nonlimiting example, a form preferred industrial achievement, to which we refer in our description.

  • L'invention se rapporte à un relais du genre de ceux qu'on utilise comme dispositif fonctionnel pour 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 se ferme au moyen d'un socle (2).The invention relates to a relay of the kind of those that we use as a functional device for various control and command functions in installations electric, said relay being essentially constituted by a functional mechanism which is housed inside a carcass (1), which closes by means of a base (2).

    Selon un exemple de réalisation pratique préféré, qui n'est pas limitatif, le socle (2) est muni d'une paroi d'emboítement dans la carcasse (1) et, sur la partie externe de cette paroi d'emboítement, font saillie des formations proéminentes (3) en forme de dents, lesquelles sont susceptibles de s'emboíter dans des fenêtres correspondantes (4) de la paroi de la carcasse (1), en formant un encliquetage bloqueur de la fermeture dans le montage.According to a preferred practical embodiment, which is not limiting, the base (2) is provided with a wall fitting into the carcass (1) and, on the external part of this interlocking wall, protrude formations prominent (3) tooth-shaped, which are likely to fit into corresponding windows (4) from the wall of the carcass (1), forming a snap locker of the closure in the assembly.

    Le mécanisme fonctionnel de l'intérieur se compose, pour sa part, d'une façon classique, d'un électro-aimant (5) et d'une pièce métallique mobile (6) pouvant être commandée par celui-ci mais, d'une façon qui se conforme à la solution préconisée, ladite pièce mobile (6) est disposée en montage basculant, sur une pièce support (7), étant en outre sollicitée en attraction, depuis sa partie arrière, par un ressort (8), par rapport à une pièce de base (9) sur laquelle est située la pièce support (7) mentionnée, de sorte que, sous l'action du ressort cité (8), cette pièce mobile (6)tend à se maintenir écartée de l'électro-aimant (5).The functional mechanism of the interior consists, for its share, in a conventional manner, of an electromagnet (5) and a movable metal part (6) which can be controlled by this one but, in a way that conforms to the solution recommended, said movable part (6) is arranged in assembly tilting, on a support piece (7), being further requested in attraction, from its rear part, by a spring (8), relative to a base part (9) on which is located the support piece (7) mentioned, so that, under the action of the cited spring (8), this movable part (6) tends keep away from the electromagnet (5).

    La pièce de base (9) mentionnée qui, de même que la carcasse (1), le socle (2) et la pièce support (7), est faite d'une matière synthétique isolante de l'électricité, définit, unitairement avec elle, une formation (10) constitutive du corps de bobine pour le bobinage de la bobine (11) correspondante de l'électro-aimant (5).The aforementioned basic part (9) which, like the carcass (1), the base (2) and the support part (7), is made of an electrically insulating synthetic material, defines, unitarily with it, a formation (10) constituting the coil body for winding the coil (11) corresponding to the electromagnet (5).

    Ladite pièce (9) définit en outre des formations latérales (12) au moyen duquel elle est susceptible d'établir un encliquetage de fixation dans le montage, par rapport à deux fenêtres (13) correspondantes de la paroi d'emboítement du socle (2), comme on peut l'observer sur la figure 3 ; cette pièce (9) définissant d'autre part des ailes horizontales saillantes (14) avec lesquelles elle s'appuie sur le bord supérieur de la paroi d'emboítement mentionnée du socle (2), lesdites ailes (14) étant à leur tour retenues dans le montage par la carcasse (1), comme on peut l'observer sur la figure 2 ; de cette façon, on obtient un montage totalement bloqué de tout l'ensemble, ce qui permet de maintenir avec une exactitude totale des distances fixes dans le montage, en obtenant ainsi un positionnement exact et stable des éléments fonctionnels et, en conséquence, une grande précision opérationnelle du fonctionnement.Said part (9) further defines formations side (12) by means of which it is capable of establishing a fixing snap in the assembly, relative to two windows (13) corresponding to the socket wall the base (2), as can be seen in Figure 3; this part (9) defining on the other hand wings horizontal projections (14) with which it rests on the upper edge of the mentioned interlocking wall of the base (2), said wings (14) being in turn retained in the mounting by the carcass (1), as can be observed in Figure 2; this way, we get a montage completely blocked from the whole, which allows maintain with total accuracy fixed distances in mounting, thus obtaining an exact positioning and stable functional elements and, consequently, a high operational precision of operation.

    Le noyau de l'électro-aimant (5) est constitué à son tour par une pièce métallique (15) en forme de "U", laquelle s'emboíte axialement par une de ses branches à travers le corps de bobine (10) de l'électro-aimant (5), en définissant le noyau proprement dit de celui-ci ; tandis que l'autre branche de ladite pièce (15) passe à travers une ouverture (16) de la pièce de base (9), en s'emboítant de l'autre côté dans un logement (17) défini par la pièce support (7) ; de sorte qu'ainsi, au moyen de cette pièce (15), on établit à la fois la fixation de la pièce support (7) citée et la formation du noyau fonctionnel de l'électro-aimant (5). Ladite pièce (15) se disposant en appui sur un aimant permanent (18) qui se trouve disposé sur le socle (2).The core of the electromagnet (5) is formed at its tower by a metal part (15) in the shape of "U", which fits axially by one of its branches through the coil body (10) of the electromagnet (5), defining the actual nucleus thereof; while the other branch of said piece (15) passes through an opening (16) of the base part (9), fitting on the other side in a housing (17) defined by the support part (7); of so that, by means of this piece (15), it is established at the both the attachment of the support piece (7) cited and the formation of the functional core of the electromagnet (5). Said part (15) which rests on a magnet permanent (18) which is arranged on the base (2).

    La pièce (15) mentionnée présente en outre une empreinte (22), dans la face interne de sa branche d'emboítement dans la pièce support (7), tandis que la paroi respective de la pièce support (7) citée présente une protubérance correspondante (23) ; de sorte que, lors de l'emboítement de ladite branche de la pièce (15) dans le logement (17), il s'établit en supplément un encliquetage qui assure la stabilité du montage ; étant prévu qu'entre la protubérance (23) et l'empreinte (22), il existe un léger déphasage vertical, de sorte que, lors de l'établissement de l'encliquetage bloqueur mentionné, il se crée, par l'effet propre de celui-ci, un effort sur la pièce (15), vers le haut, en évitant ainsi tout jeu quelconque possible de mobilité de cette pièce par rapport à la position exacte de montage pour l'appui correct de la pièce basculante (6) dans cette pièce.The part (15) mentioned also has an imprint (22), in the internal face of its socket branch in the support piece (7), while the respective wall of the support piece (7) cited has a protuberance corresponding (23); so that when nesting said branch of the part (15) in the housing (17), it in addition, a snap-in is established which ensures mounting stability; provided that between the protuberance (23) and the imprint (22), there is a slight phase shift vertical, so that when establishing the locking block mentioned, it is created by the effect clean of it, an effort on the part (15), towards the high, thus avoiding any possible play of mobility of this part in relation to the exact position of mounting for correct support of the tilting part (6) in this piece.

    Selon une forme préférée de réalisation, la pièce basculante (6) est constituée par une petite plaque rectangulaire en forme de palette, laquelle présente un axe transversal (19) qui y est réuni solidairement, par exemple, par soudage au laser, de manière que la précision dimensionnelle de l'ensemble soit déterminée par l'outillage de soudage, ledit axe (19) s'emboítant par ses extrémités dans des emboítures correspondantes (20) de la pièce support (7), qui servent d'appuis de rotation pour le basculement.According to a preferred embodiment, the part tilting (6) consists of a small plate rectangular in shape of a pallet, which has an axis transverse (19) which is joined therein solidly, for example, by laser welding, so that the precision dimension of the assembly is determined by the tooling welding, said axis (19) fitting at its ends in corresponding sockets (20) of the support part (7), which serve as rotational supports for tilting.

    Avec tout ceci, lorsque l'électro-aimant (5) se trouve désactivé, la pièce (6) reste basculée de sorte qu'elle est en permanence collée à l'électro-aimant (5), sous l'effet du flux magnétique que l'aimant (18) établit dans la pièce (15) du noyau, ainsi qu'on peut le voir sur la figure 4.With all this, when the electromagnet (5) is deactivated, the part (6) remains tilted so that it is permanently glued to the electromagnet (5), under the effect of magnetic flux that the magnet (18) establishes in the room (15) of the nucleus, as can be seen in Figure 4.

    Et lorsque, dans cette situation, l'électro-aimant (5), est activé par une alimentation de courant à la bobine (11), le flux magnétique que la pièce de noyau (15) acquiert en conséquence s'oppose à celui créé par l'aimant (18), ce qui fait que la force d'attraction sur la pièce (6) diminue, celle-ci basculant en conséquence sous l'effet de la tension du ressort (8) sur la partie arrière de cette dernière, jusqu'à une position écartée de l'électro-aimant (5), comme on le voit sur la figure 5, à partir de laquelle, pour retrouver de nouveau la position armée de la figure 4, il est nécessaire, une fois disparu le courant de la bobine (11), de pousser la pièce (6) à l'encontre de la tension du ressort (8), jusqu'au contact avec l'électro-aimant (5), ce pourquoi on dispose d'un pivot (21) qui apparaít à travers la carcasse (1) à l'aide duquel peut se faire l'actionnement de la poussée mentionnée. And when, in this situation, the electromagnet (5), is activated by a current supply to the coil (11), the magnetic flux that the core part (15) acquires in consequence is opposed to that created by the magnet (18), which causes the attraction force on the part (6) to decrease, it tilts accordingly under the effect of tension spring (8) on the rear part of the latter, to a position away from the electromagnet (5), as seen in Figure 5, from which, for find again the armed position of figure 4, it is necessary, once the current from the coil (11) has disappeared, push the workpiece (6) against the spring tension (8), up to contact with the electromagnet (5), which is why there is a pivot (21) which appears through the carcass (1) with which the actuation of the thrust mentioned.

    En particulier, la disposition du ressort (8) est prévue de manière qu'il soit disposé avec une inclinaison vers l'intérieur depuis son accrochage sur la pièce (6) jusqu'à la fixation antagoniste sur la pièce de base (9), de sorte qu'en supplément de la traction servant pour le basculement fonctionnel de la pièce (6) mentionnée, ledit ressort (8) détermine aussi une tension qui favorise l'emboítement de l'axe (19) dans les logements (20), en établissant ainsi une sécurité du maintien du montage de l'ensemble.In particular, the arrangement of the spring (8) is provided so that it is inclined towards the interior from its attachment on the part (6) to the antagonistic fixing on the base part (9), so that in additional traction for tilting functional of the part (6) mentioned, said spring (8) also determines a tension that promotes the nesting of the axis (19) in the housings (20), thereby establishing a security in maintaining the assembly of the assembly.

    Et, à son tour en accord avec une réalisation préférée, on prévoit, pour la connexion électrique de la bobine (11) des bornes (24) constituées par des tiges métalliques respectives qui sont incrustées en position fixe sur la pièce (9), en faisant saillie à l'extérieur à travers le socle (2), comme on le voit sur la figure 7 ; tandis que les extrémités du fil conducteur (25) de la bobine (11) font saillie de même à l'extérieur, en se disposant en enroulement sur les bornes (24) mentionnées, par rapport auxquelles elles se fixent dans le segment final par soudage, opération qui peut être réalisée après la fermeture de la carcasse (1) par le socle (2), en permettant ainsi de conserver une totale propreté de l'intérieur.And, in turn in keeping with a favorite achievement, provision is made for the electrical connection of the coil (11) terminals (24) constituted by metal rods which are embedded in a fixed position on the workpiece (9), projecting outside through the base (2), as seen in Figure 7; while the ends of the conductor wire (25) of the coil (11) also project outside, by winding on the terminals (24) mentioned, in relation to which they are fixed in the final segment by welding, an operation which can be made after the carcass (1) is closed by the base (2), thus allowing to keep a total cleanliness of the interior.

    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.
