Description

L'invention concerne les relais électromagnétiques du type à empilage de lames de contact électrique notamment pour télécommunications.The invention relates to electromagnetic relays of the stacking type of electrical contact blades, in particular for telecommunications.

Il est connu de réaliser des blocs d'empilages de lames de contact comportant au moins un empilage de lames métalliques séparées par un matériau isolant. Ce matériau peut être constitué de plaquettes obtenues par découpage ou par moulage, l'ensemble lames-plaquettes étant fixé à la culasse du relais.It is known to produce blocks for stacking contact blades comprising at least one stack of metal blades separated by an insulating material. This material can consist of plates obtained by cutting or by molding, the blade-plate assembly being fixed to the cylinder head of the relay.

L'empilage des lames de contact et des plaquettes nécessite un alignement précis pour que les contacts en regard à l'extrémité desdites lames puissent s'établir sur une surface optimum. Un centrage approximatif peut être obtenu par fixation de l'empilage sur la culasse du relais au moyen de deux vis ou rivets traversant l'ensemble lames-plaquettes. Ceci a pour inconvénient de nécessiter un dimensionnement important des lames et un certain 'jeu entre le diamètre des vis et des trous de perçage.The stacking of the contact blades and of the plates requires precise alignment so that the facing contacts at the end of said blades can be established on an optimum surface. An approximate centering can be obtained by fixing the stack to the cylinder head of the relay by means of two screws or rivets passing through the blade-insert assembly. This has the disadvantage of requiring a large dimensioning of the blades and a certain 'clearance between the diameter of the screws and the drilling holes.

Une solution pour un alignement plus précis de.lames d'un faible encombrement consiste à n'utiliser qu'une seule vis de fixation pour un bloc de deux empilages de._lames, lesdites lames de chaque empilage étant centrées par deux broches isolantes traversant l'ensemble plaquettes- lames dans l'axe de symétrie desdites lames. Cependant ces broches isolantes doivent être calibrées avec précision, ce qui pèse de façon sensible sur le coût du produit.A solution for a more precise alignment of . blades of a small size consists in using only one fixing screw for a block of two stacks of._lames, said blades of each stack being centered by two insulating pins crossing the whole plates-blades in the axis of symmetry of said blades. However, these insulating pins must be calibrated with precision, which weighs significantly on the cost of the product.

Un autre moyen de réalisation de bloc d'empilage consiste à effectuer un enrobage d'une partie de chaque lame dans de la matière isolante en fusion pour obtenir une lame-plaquette et à positionner celles-ci selon la solution précédente. Un autre moyen consiste à positionner dans un moule spécial les lames d'un ou plusieurs empilages et à remplir le moule de matière isolante en fusion.Another means of producing a stacking block consists in coating part of each blade in molten insulating material to obtain a blade-plate and in positioning them according to the previous solution. Another way is to position the blades of one or more stacks in a special mold and fill the mold with molten insulating material.

Ces modes de réalisation de blocs d'empilages par enrobage à chaud des lames ont pour inconvénient de provoquer une dégradation de l'élasticité des lames et de créer des tensions internes occasionnant des déréglages des cotes au niveau des contacts.These embodiments of stacking blocks by hot-coating of the blades have the drawback of causing a degradation of the elasticity of the blades and of creating internal tensions causing the dimensions to be adjusted at the level of the contacts.

La présente invention a pour but d'éviter les inconvénients ci-dessus en réalisant un relais doté d'un bloc d'empilages incluant des moyens permettant l'alignement précis des lames des empilages en colonnes. L'invention permet également de réaliser un bloc d'empilages économique en diminuant le nombre de pièces constitutives du bloc.The present invention aims to avoid the above drawbacks by providing a relay with a stacking block including means allowing the precise alignment of the blades of the stacked columns. The invention also makes it possible to produce an economic stacking block by reducing the number of component parts of the block.

Un type d'empilage classique de relais comporte, pour éviter les rebondissements des contacts, des lames métalliques minces et flexibles porteuses desdits contacts. Certaines de ces lames, dites "passives" car n'étant pas sollicitées par l'armature du relais, sont partiellement accolées à des lames métalliques rigides ou contre-lames.Ces contre-lames ont pour but d'assurer aux lames passives une position stable de référence permettant d'améliorer la constance de la course des lames actives commandées par l'armature et, la constance des cotes au niveau des contacts.A conventional type of relay stacking comprises, to avoid bouncing of the contacts, thin and flexible metal blades carrying said contacts. Some of these blades, called "passive" because they are not stressed by the relay frame, are partially attached to rigid metal blades or counter-blades. These counter-blades are intended to ensure that the passive blades have a position reference stable allowing to improve the constancy of the stroke of the active blades controlled by the armature and, the constancy of the dimensions at the level of the contacts.

Cependant, dans la constitution de blocs à plusieurs empilages, les contre-lames de même rang desdits empilages sont rarement disposées au montage dans un même plan, ce qui entraîne une dispersion dans l'alignement des contacts des rangées de lames en appui sur les contre-lames et nécessite un réglage manuel par flexions opérées à la base desdites contre-lames. La présente invention a également pour but de réaliser un bloc d'empilages comportant des moyens d'auto-positionnement dans un même plan des lames de même rang.However, in the constitution of blocks with several stacks, the counter blades of the same row of said stacks are rarely arranged for mounting in the same plane, which results in a dispersion in the alignment of the contacts of the rows of blades resting on the counter -blades and requires manual adjustment by bending at the base of said counter-blades. The present invention also aims to produce a stacking block comprising self-positioning means in the same plane of the blades of the same rank.

Les moyens actuels de fixation du bloc d'empilages par une seule vis ou rivet traversant la partie centrale du bloc d'empilages ou par bride encerclant ledit bloc ont pour inconvénient de concentrer la pression sur la zone centrale des plaquettes dont les parties latérales tendent à s'écarter en éventail de part et d'autre de ladite pression centrale. La présente invention a également pour but la fixation du bloc d'empilages en assurant une pression sensiblement uniforme répartie sur la surface des plaquettes.The current means of fixing the stacking block by a single screw or rivet passing through the central part of the stacking block or by flange encircling said block have the disadvantage of concentrating the pressure on the central zone of the plates whose lateral parts tend to deviate as a fan on either side of said central pressure. The present invention also aims to fix the stacking block while ensuring a substantially uniform pressure distributed over the surface of the wafers.

L'invention a pour objet un relais électromagnétique à empilages de lames de contact électrique fixes et mobiles comportant un bloc support d'empilages fixé sur une culasse du relais, caractérisé par le fait que le bloc d'empilages est constitué de plaquettes isolantes emboîtables les unes dans les autres et enserrant entre elles les lames de contact fixes et mobiles de façon à assurer un positionnement en alignement des lames de contact.The subject of the invention is an electromagnetic relay with stacks of fixed and movable electrical contact blades comprising a stacking support block fixed to a yoke of the relay, characterized in that the stacking block consists of insulating plates which can be inserted together one inside the other and enclosing between them the fixed and movable contact blades so as to ensure positioning in alignment with the contact blades.

Les plaquettes, lames et broches sont assemblées en jeux J1, J2, J3 pour constituer des jeux d'extrémité J1, J2 du bloc d'empilages et des jeux J3 intérieurs audit bloc. Ce préassemblage des éléments par jeux J1, J2, J3, facilite le stockage et permet de fabriquer des relais à nombre de contacts variant à la demande, par simple emboîtage d'une combinaison desdits jeux, les blocs d'empilages étant ainsi réalisés de façon modulaire.The plates, blades and pins are assembled in sets J1, J2, J3 to form end sets J1, J2 of the stacking block and sets J3 inside said block. This pre-assembly of the elements by sets J1, J2, J3, facilitates storage and makes it possible to manufacture relays with number of contacts varying on request, by simple fitting of a combination of said sets, the stacking blocks thus being produced so modular.

Le bloc d'empilages détaillé figures 2 et 4 peut être fixé à la culasse par deux moyens différents permettant d'effectuer une pression répartie sur ledit bloc.The stacking block detailed in FIGS. 2 and 4 can be fixed to the cylinder head by two different means making it possible to apply distributed pressure on said block.

Un premier moyen de fixation consiste en une barrette 12 (fig.6) à branches flexibles comprenant de part et d'autre d'une partie centrale rigide une partie droite 15 et une extrémité courbe 16. La partie centrale de la plaquette présente un renforcement annulaire 17 percé d'un trou 18. La barrette 12 est disposée dans le logement 70 de la plaquette extrême 11 et les têtons 60 de la plaquette extrême 7 sont ajustés dans les trous 85 du socle 2 (figures 5, 6 et 9) fixé transversalement sur la culasse 1 du relais. Ledit socle comporte au centre un trou fileté 87 dans lequel est vissé l'extrémité filetée de la vis 13 qui applique le bloc d'empilages contre le socle par pression de la partie centrale 17 et des parties extrêmes 16 de la barrette. Le socle comporte en regard de l'armature 88 un évidement 89 permettant le libre jeu de ladite armature.A first fixing means consists of a bar 12 (fig. 6) with flexible branches comprising on either side of a central part rigid a straight part 15 and a curved end 16. The central part of the plate has an annular reinforcement 17 pierced with a hole 18. The bar 12 is disposed in the housing 70 of the end plate 11 and the pins 60 of the plate end 7 are adjusted in the holes 85 of the base 2 (Figures 5, 6 and 9) fixed transversely on the cylinder head 1 of the relay. Said base has in the center a threaded hole 87 into which is screwed the threaded end of the screw 13 which applies the stacking block against the base by pressing the central part 17 and end parts 16 of the bar. The base comprises opposite the frame 88 a recess 89 allowing the free play of said frame.

Un autre moyen de fixation consiste en une bride 90 en U flexible (fig.10) dont la branche commune comporte vers l'intérieur du U un bombement central 91, et deux bombements latéraux 92, 93. La branche commune de la bride est placée dans la partie évidée 70 de la plaquette 11 du bloc d'empilages. Dans ce mode de fixation (fig. 11) la culasse ne comporte pas de socle 2 mais deux échancrures latérales 94 recevant les extrémités 95 de la bride 90 et les têtons du bloc d'empilages. Les bombements de la bride exercent une pression de serrage des plaquettes répartie sur les zones centrale et latérale desdites plaquettes.Another fastening means consists of a flexible U-shaped flange 90 (fig. 10), the common branch of which has inwardly of the U a central bulge 91, and two lateral bulges 92, 93. The common branch of the flange is placed in the hollowed out part 70 of the plate 11 of the stacking block. In this method of attachment (FIG. 11) the cylinder head does not have a base 2 but two lateral notches 94 receiving the ends 95 of the flange 90 and the pins of the stacking block. The bulges of the flange exert a clamping pressure of the pads distributed over the central and lateral zones of said pads.
