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 operation of which the relays are among the most widely used devices, 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 the latter between two or more than two positions for the accomplishment of any specific concrete function which can be, for example example, closing and opening a conduit, etc.

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 fundamental characteristic is generally functional precision and, in this sense, new developments are continually being developed, while trying to combine it 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 is proposed which has been improved, in its constructive and functional characteristics, so as to obtain a very advantageous embodiment relative to those of similar devices known to date.

Ce relais objet de l'invention est essentiellement constitué par une carcasse contenante munie d'un socle de fermeture et de moyens servant à la fixer au lieu d'application, cependant qu'il y a à l'intérieur un ensemble fonctionnel formé d'une pièce de base qui forme dans sa propre conformation le corps pour la bobine de l'électroaimant, et par une pièce complémentaire sur laquelle se dispose, en montage basculant, la pièce métallique mobile pouvant être commandée par l'électro-aimant, laquelle est sollicitée vers un positionnement normal d'écartement par rapport à l'électro-aimant par un ressort de traction incorporé entre elle-même et la pièce de support, ledit support de la pièce basculante mentionnée étant lui-même assujetti sur la pièce de base par l'élément même qui forme le noyau de l'électro-aimant, qui est constitué par une pièce en forme de "U", laquelle est positionnée en contact avec un aimant permanent logé dans le socle.This relay object of the invention is essentially constituted by a containing carcass provided with a closing base and means serving to fix it at the place of application, while there is inside a functional unit formed of a basic piece that forms in its own conformation of the body for the electromagnet coil, and by a complementary part on which is disposed, in tilting assembly, the movable metal part which can be controlled by the electromagnet, which is biased towards a normal spacing position relative to the electromagnet by a tension spring incorporated between itself and the support piece, said support of the mentioned tilting piece being itself secured to the base piece by the very element which forms the core of the electromagnet, which consists of a "U" shaped piece, which is positioned in contact with a permanent magnet housed in the base.

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, an extremely simple structural assembly is obtained, based on a minimal number of constituent elements, the simplicity of which allows great ease of construction and assembly, giving rise to a functional assembly which is distinguished by an absence total of complexities, resulting in 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.In total, this recommended relay certainly has very advantageous characteristics which give its realization a life of its own and a preferable character 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 emboîtement 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 that is used as a functional device for carrying out various control and command functions in electrical installations, said relay being essentially constituted by a functional mechanism which is found housed inside a carcass (1), which, according to an exemplary embodiment, is closed by means of a base (2) which is fixed by interlocking of lateral pins (3) in corresponding orifices (4 ) of the carcass (1), however, that the latter is in turn provided with formations (5) for fixing, by screwing or any other similar means, to 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 consists, in turn, in a conventional manner, of an electromagnet (6) and a movable part (7) which can be controlled by it but, in particular, said movable part (7) being arranged in a tilting arrangement, mounted on a respective support (8) with respect to which it is also attracted at its rear part by a spring (9) which tends to keep it separated from the electromagnet (6) as can be seen in 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).Said mechanism further comprises a base part (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 plate-shaped body, on which rises an integral formation (11) which constitutes the coil body for the winding of the corresponding coil (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'emboîte 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'emboîtant 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) is in turn constituted by a metal part (13) in the shape of a "U", which is axially fitted by one of its branches through the coil body (11) , forming the core proper, while the other branch passes through a respective opening (14) of the flat body of the part (10), fitting on the other side into a housing (21) defined by the support (8) of the tilting part (7), so that, by means of said part (13) which constitutes the core, it establishes both the fixing of the support (8) mentioned and the formation of the functional core of the electromagnet (6) mentioned; the part (13) mentioned being placed in abutment on 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'emboîtent dans des encoches de logement correspondantes (20).According to a preferred embodiment, the tilting part (7) mentioned consists of a metal plate (15) in the form of a pallet and a supporting part (16) in the shape of a "U", the two being joined together by fixed fixing by stamping. , spot welding or any other 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 relative to another reciprocal attachment formation (18) defined in the support (8); while, laterally, this part (16) forms small pins (19) which serve as tilting axes for mounting on the support (8), in the sense that the latter fit into corresponding housing notches ( 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 of this, when the electromagnet (6) is de-energized, the part (7) remains tilted in such a way that the pallet (15) remains stuck to said electromagnet (6), due to the magnetic flux established in the core part (13) by the magnet (22), as can be seen in FIG. 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 supplying current 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 of the part (7) tilting accordingly under the effect of the tension of the spring (9), to a position such that that shown in Figure 2, from which the return to the previous position of Figure 3 occurs when the relay is again 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'emboîtement 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'emboîter 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 embodiment of a shape in which the base (2) forms a wall (24) nesting in the carcass (1), while on the outside of said wall (24), protruding protrusions (25) , which are capable of fitting into corresponding windows (26) of the wall of the carcass (1), to establish the fixing of the closure in the assembly; while the base part (10), which comprises the coil body (11), in turn forms in its sides 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 FIG. 6, this part (10) further forming projecting horizontal wings (29) with which it bears on the upper edge of the wall (24) of the base (2), so as to be in their turn blocked in the assembly by the carcass (1), as can be seen in FIG. 5, so that a completely fixed assembly of all is obtained 'the whole relay; by allowing fixed distances to be maintained inside the assembly, so that an exact and stable positioning of the elements of the mechanism is obtained and the subsequent obtaining of high operating precision.

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.The nature of the present invention, as well as its industrial implementation, being sufficiently described, it should only be added that it is possible to introduce changes in shape, material and arrangement as a whole and in its constituent parts, without going out of the scope of the invention, provided that these alterations do not depart from its principle.
