Description

L'invention est relative à un télérupteur à boîtier moulé miniature dans lequel sont logés:

  • un électro-aimant à palette pivotante de commande à distance,
  • un mécanisme de commande ayant un balancier monté à pivotement et susceptible d'occuper deux positions extrêmes stables,
  • un organe de commande solidaire de la palette et coopérant avec le balancier pour déplacer positivement ce dernier d'une position stable vers l'autre position stable à chaque manoeuvre de la palette,
  • un contact basculant mobile qui coopère avec un contact fixe et qui est solidarisé à un bras de contact qui coopère avec ledit balancier, pour déplacer le contact basculant de la position fermé à la position ouvert et inversement lors du passage du balancier de l'une des positions stables vers l'autre et inversement,
  • une paire de bornes de puissance disposées sur les deux faces latérales étroites opposées, l'une des bornes étant reliée au contact fixe et l'autre borne étant reliée au contact basculant par un conducteur rigide dont l'extrémité constitue l'articulation du contact basculant.
The invention relates to a miniature molded case remote control switch in which are housed:
  • an electromagnet with a swiveling remote control paddle,
  • a control mechanism having a pendulum mounted pivotally and capable of occupying two stable extreme positions,
  • a control member secured to the pallet and cooperating with the pendulum to positively move the latter from a stable position to the other stable position at each operation of the pallet,
  • a movable rocking contact which cooperates with a fixed contact and which is secured to a contact arm which cooperates with said pendulum, for moving the rocking contact from the closed position to the open position and vice versa during the passage of the pendulum from one of the stable positions towards each other and vice versa,
  • a pair of power terminals arranged on the two opposite narrow side faces, one of the terminals being connected to the fixed contact and the other terminal being connected to the rocking contact by a rigid conductor the end of which constitutes the articulation of the rocking contact .

La présente invention est basée sur la constatation que la durée de vie d'un télérupteur du genre mentionné (brevet français n°2.482.773) est essentiellement déterminée par l'usure de l'articulation du contact basculant. Cette articulation assure également le contact électrique entre la partie fixe et le contact basculant mobile, et toute usure provoque une détérioration de ce contact électrique et une destruction rapide.The present invention is based on the observation that the lifespan of a remote control switch of the type mentioned (French Patent No. 2,482,773) is essentially determined by the wear of the articulation of the rocking contact. This articulation also ensures the electrical contact between the fixed part and the movable rocking contact, and any wear causes deterioration of this electrical contact and rapid destruction.

La présente invention a pour but d'améliorer cette articulation du contact basculant sur la partie fixe d'amenée de courant, tout en réduisant le coût de fabrication.The object of the present invention is to improve this articulation of the rocking contact on the fixed current supply part, while reducing the manufacturing cost.

Le télérupteur selon l'invention est caractérisé en ce que le bras de contact comporte une entaille transversale en V, que ladite extrémité du conducteur rigide est taillée en couteau de forme conjuguée à celle de l'entaille en V, pour constituer avec cette dernière une articulation à couteau et qu'un ressort à lame bistable coopère par l'une de ses extrémités avec ledit conducteur rigide et par l'extrémité opposée avec le contact basculant pour, d'une part maintenir en engagement l'entaille en V sur le couteau, et d'autre part solliciter le contact basculant vers les positions stables d'ouverture et de fermeture desdits contacts.The remote control switch according to the invention is characterized in that the contact arm comprises a transverse notch in V, that said end of the rigid conductor is cut into a knife of shape combined with that of the notch in V, to constitute with the latter a knife joint and that a bistable leaf spring cooperates by one of its ends with said rigid conductor and by the opposite end with the rocking contact in order, on the one hand to maintain in engagement the V-notch on the knife , and secondly solicit the rocking contact to the stable open and closed positions of said contacts.

En élargissant la portée de l'articulation, qui n'est plus limitée à deux points, mais qui s'étend sur toute la longueur du couteau, le risque d'une usure prématurée est quasiment éliminé. Le ressort à lame bistable assure un appui correct du couteau dans l'entaille en V et l'encombrement de ce ressort est extrêment réduit, tout en permettant le montage aisé d'un sous-ensemble constitué par le conducteur fixe d'amenée de courant et le contact basculant avec son ressort à lame bistable. L'entaille en V est avantageusement revêtue d'une couche d'argent qui améliore le contact électrique avec le couteau, généralement en cuivre ou en alliage de cuivre. Cette couche d'argent peut être une simple bande reportée sur le contact basculant avant son estampage et de découpage. Un moyen de centrage basculant avant son estampage et découpage. Un moyen de centrage à nervure et rainure positionne l'entaille en V sur le couteau.By widening the range of the joint, which is no longer limited to two points, but which extends over the entire length of the knife, the risk of premature wear is almost eliminated. The bistable leaf spring ensures correct support of the knife in the V-notch and the size of this spring is extremely reduced, while allowing easy assembly of a sub-assembly formed by the fixed current supply conductor. and the tilting contact with its bistable leaf spring. The V-notch is advantageously coated with a layer of silver which improves the electrical contact with the knife, generally made of copper or a copper alloy. This silver layer can be a simple strip transferred to the rocking contact before it is stamped and cut. A tilting centering means before its stamping and cutting. A rib and groove centering means positions the V-notch on the knife.

Un autre but de l'invention est la simplification du montage de la palette avec son organe de commande. Selon l'invention, l'articulation de la palette sur la culasse de l'électro-aimant est polarisée par un brin d'un ressort spirale, dont le brin opposé assure le verrouillage de l'organe de commande sur la palette, tout en agissant en ressort de rappel maintenant la palette écartée de la culasse. Le même ressort assure trois fonctions ou même quatre si l'on admet que la polarisation de l'articulation consiste d'une part à positionner la palette contre une butée fixe, par exemple constituée par une paroi du boîtier, et d'autre part à maintenir la palette au contact de la surface polaire de l'armature, en évitant tout entrefer parasite. Le talon en forme de protubérance de l'organe de commande traverse un orifice ménagé dans la palette et coopère avec le brin correspondant du ressort spirale, pour être sollicité par ce dernier, en appui de la palette, tout en rappelant cette dernière en position d'écartement.Another object of the invention is the simplification of the mounting of the pallet with its control member. According to the invention, the articulation of the pallet on the yoke of the electromagnet is polarized by a strand of a spiral spring, the opposite strand of which ensures the locking of the control member on the pallet, while acting as a return spring now the pallet moved away from the cylinder head. The same spring performs three functions or even four if it is accepted that the polarization of the articulation consists on the one hand of positioning the pallet against a fixed stop, for example constituted by a wall of the housing, and on the other hand keep the pallet in contact with the pole surface of the frame, avoiding any parasitic air gap. The heel in the form of a protuberance of the control member passes through an orifice made in the pallet and cooperates with the corresponding strand of the spiral spring, to be urged by the latter, in support of the pallet, while recalling the latter in position 'spacing.

L'invention a également pour but de faciliter le montage d'une bague de déphasage sur la jambe de la culasse portant la bobine de l'électro-aimant. Cette bague de déphasage en forme de cadre, dont l'un des côtés est inséré dans une rainure pratiquée dans la surface polaire de la culasse, est solidarisée à la carcasse de la bobine, de telle manière que la mise en place de cette carcasse sur la jambe de la culasse, amène automatiquement la bague de déphasage dans sa position d'insertion dans ladite rainure. On évite ainsi une opération de mise en place de la bague de déphasage, séparée de l'opération de montage de la bobine. La bague de déphasage est simplement insérée dans une glissière venant de moulage avec la carcasse de la bobine et l'ensemble, bobine, carcasse et bague de déphasage, constitue un sous-ensemble dont le montage est aisé.The invention also aims to facilitate the mounting of a phase shift ring on the leg of the yoke carrying the coil of the electromagnet. This frame-shaped phase shift ring, one of the sides of which is inserted into a groove formed in the polar surface of the cylinder head, is secured to the coil carcass, so that the positioning of this carcass on the leg of the cylinder head, automatically brings the phase shift ring into its insertion position in said groove. This avoids an operation of placing the phase shift ring, separate from the operation of mounting the coil. The phase shift ring is simply inserted into a slide coming from molding with the carcass of the coil and the assembly, coil, carcass and phase shift ring, constitutes a sub-assembly whose assembly is easy.

Selon un autre développement de l'invention, on constitue un contact auxiliaire pour télérupteur à partir des mêmes éléments de base que le télérupteur, en modifiant simplement la liaison entre le balancier et le contact basculant. Les contacts auxiliaires généralement insérés dans le circuit de commande doivent s'ouvrir légèrement en retard des contacts du télérupteur afin de ne pas interrompre prématurément l'alimentation de l'électro-aimant, et cette temporisation est obtenue en insérant entre le balancier et le contact basculant, une lame élastique. Lorsque le contact auxiliaire est un contact inverseur, la lame élastique assure automatiquement la temporisation dans les deux sens de mouvement.According to another development of the invention, an auxiliary contact for a remote control switch is constituted from the same basic elements as the remote control switch, by simply modifying the connection between the balance and the tilting contact. The auxiliary contacts generally inserted in the control circuit must open slightly behind the contacts of the remote control switch so as not to prematurely interrupt the supply of the electromagnet, and this time delay is obtained by inserting between the balance and the contact tilting, an elastic blade. When the auxiliary contact is a contact reversing switch, the elastic blade automatically provides time delay in both directions of movement.

Un mode de mise en oeuvre de l'invention est donné à titre d'exemple non limitatif et représenté aux dessins annexés dans lesquels:An embodiment of the invention is given by way of nonlimiting example and shown in the appended drawings in which:

La figure 8 est une vue en perspective montrant le sous-ensemble carcasse, bague de déphasage avant son introduction sur la culasse.Figure 8 is a perspective view showing the carcass sub-assembly, phase shift ring before its introduction on the cylinder head.

Sur les figures un boîtier moulé miniature 10, contient un électro-aimant 11, un mécanisme de commande 12 et un circuit électrique de puissance 13. Le circuit 13 comporte un contact mobile basculant 14 agencé en contact inverseur qui coopère avec une paire de contacts fixes 15,16 reliés à des bornes 17,18. Le contact basculant 14 est relié électriquement par un conducteur rigide 19 à une borne opposée 20.L'extrémité,opposée à la borne 20, du conducteur rigide 19 est taillée en couteau 21, engagée dans une entaille en forme de V 22, du contact basculant 14 pour constituer une articulation à couteau. Un ressort à lame 23 présente deux extrémités recourbées dont l'une 24 est ancrée dans un orifice 25 ménagé dans le conducteur fixe 19 et dont l'autre extrémité 26 est engagée dans un orifice du contact basculant 14. La position relative de l'articulation 21,22 et des points d'appui du ressort à lame 23 est telle que ce ressort est bistable et sollicite sélectivement le contact basculant 14 vers la position d'ouverture et de fermeture. Le ressort à lame bistable 23 s'étend parallèlement à proximité du conducteur fixe 19 sans occuper une place importante à l'intérieur du boîtier 10. L'entaille en V 22 présente une nervure centrale 50 qui s'emboîte dans une encoche du couteau 21 pour éviter tout décalage latéral.In the figures, a miniature molded case 10 contains an electromagnet 11, a control mechanism 12 and an electrical power circuit 13. The circuit 13 includes a contact tilting mobile 14 arranged in reversing contact which cooperates with a pair of fixed contacts 15,16 connected to terminals 17,18. The tilting contact 14 is electrically connected by a rigid conductor 19 to an opposite terminal 20. The end, opposite the terminal 20, of the rigid conductor 19 is cut into a knife 21, engaged in a V-shaped notch 22, of the contact tilting 14 to form a knife joint. A leaf spring 23 has two curved ends, one of which 24 is anchored in an orifice 25 formed in the fixed conductor 19 and the other end of which is engaged in an orifice of the rocking contact 14. The relative position of the articulation 21, 22 and the support points of the leaf spring 23 is such that this spring is bistable and selectively biases the rocking contact 14 towards the open and closed position. The bistable leaf spring 23 extends parallel near the fixed conductor 19 without occupying an important place inside the housing 10. The V-shaped notch 22 has a central rib 50 which fits into a notch in the knife 21 to avoid any lateral shift.

L'électro-aimant 11 comporte une culasse 27 en forme de E, dont la jambe centrale porte une bobine 28 et dont une jambe latérale 29 porte une palette 30. La palette 30 est maintenue en appui de la surface polaire d'extrémité de la jambe 29 par un ressort spirale 31,dont l'un des brins 32 pénètre dans un orifice ménagé dans la palette 30. Ce même brin 32 sollicite la palette 30 en appui d'une butée fixe 33 ménagée sur la paroi du boîtier 10. Il est facile de voir que cet ensemble constitue une articulation permettant un pivotement de la palette 30 en étant maintenue au contact de la surface polaire de la culasse de l'électo-aimant 11.The electromagnet 11 comprises an E-shaped cylinder head 27, the central leg of which carries a coil 28 and the lateral leg of which carries a pallet 30. The pallet 30 is held in abutment against the pole end surface of the leg 29 by a spiral spring 31, one of the strands 32 of which enters an orifice provided in the pallet 30. This same strand 32 urges the pallet 30 to bear a fixed stop 33 formed on the wall of the housing 10. It It is easy to see that this assembly constitutes an articulation allowing the pallet 30 to pivot while being held in contact with the pole surface of the yoke of the electromagnet 11.

La palette 30 porte à son extrémité opposée à l'articulation un organe de commande 34 susceptible de coopérer avec un balancier 35. L'organe de commande 34 présente à l'une de ses extrémités une protubérance ou queue 36 qui traverse un orifice ménagé dans la palette 30. Cette queue 36 est maintenue par le brin 37 du ressort à spirale 31 opposé au brin 32, lequel brin 37 traverse un trou ménagé dans la queue 36. Il est facile de voir que ce brin 37 verrouille, d'une part l'organe de commande 34 sur la palette 30 tout en autorisant un mouvement de pivotement limité, et d'autre part sollicite la palette 30 en position d'écartement de la culasse de l'électro-aimant 11. L'organe de commande 34 porte à son extrémité opposée deux doigts 38 qui coopèrent avec le balancier 35, de manière à inverser la position de ce dernier à chaque cycle d'attraction de la palette 30. Le balancier 35 commande à son tour le contact basculant 14 dont le bras de contact 39 est engagé dans une rainure 40, ménagée dans le balancier 35. Un tel mécanisme 12 est bien connu en soi, et il suffit de rappeler qu'à chaque pivotement de la palette 30, le contact basculant 14 change de position.The pallet 30 carries at its end opposite the articulation a control member 34 capable of cooperating with a pendulum 35. The control member 34 has at one of its ends a protuberance or tail 36 which passes through an orifice formed in the pallet 30. This tail 36 is held by the strand 37 of the spiral spring 31 opposite the strand 32, which strand 37 passes through a hole made in the tail 36. It is easy to see that this strand 37 locks, on the one hand the control member 34 on the pallet 30 while allowing a limited pivoting movement, and on the other hand biases the pallet 30 in the spacing position of the yoke of the electromagnet 11. The control member 34 carries at its opposite end two fingers 38 which cooperate with the balance 35, so as to reverse the position of the latter at each cycle d attraction of the pallet 30. The balance 35 in turn controls the tilting contact 14, the contact arm 39 of which is engaged in a groove 40 formed in the balance 35. Such a mechanism 12 is well known in itself, and it suffices to recall that each pivoting of the pallet 30, the rocking contact 14 changes position.

En se référant plus particulièrement aux figures 7 et 8, on voit que la bobine 28 comporte une carcasse 41 à deux flasques latéraux 42 dont le flasque supérieur 42 porte sur sa face externe une glissière 43 susceptible de recevoir une bague de déphasage 44. La carcasse 41 peut être enfilée sur la jambe centrale de la culasse 27 de l'électro-aimant 11 et lors de cette insertion, la bague de déphasage 44 vient s'encastrer dans une rainure 45 ménagée dans la face polaire d'extrémité. On évite ainsi une mise en place et une fixation séparée de la bague de déphasage 44.Referring more particularly to FIGS. 7 and 8, it can be seen that the coil 28 comprises a carcass 41 with two lateral flanges 42, the upper flange 42 of which carries on its external face a slide 43 capable of receiving a phase shift ring 44. The carcass 41 can be threaded onto the central leg of the yoke 27 of the electromagnet 11 and during this insertion, the phase shift ring 44 comes to be embedded in a groove 45 formed in the pole end face. This avoids a separate positioning and fixing of the phase shift ring 44.

La figure 6 montre un contact auxiliaire susceptible d'être associé ou incorporé à un télérupteur selon la figure 1 et mettant en oeuvre les mêmes éléments constitutifs de base. On voit que la seule différence consiste dans l'insertion d'une lame élastique 46 entre le bras de contact 39 et le balancier 35. Le basculement du balancier 35 est transmis au contact auxiliaire basculant 47 après une première phase de déformation de la lame élastique 46 et le mouvement du contact auxiliaire 47 n'intervient que par la suite, lorsque la force de la lame élastique 46 arrive à vaincre l'effort fourni par le ressort à lame 23. Le contact auxiliaire 47 est accouplé à un télérupteur selon la figure 1 et les balanciers 35 sont commandés simultanément, soit par une liaison mécanique, soit par la commande électromécanique. Le contact basculant 14 suit immédiatement ce mouvement pour amorcer l'ouverture ou la fermeture du télérupteur, tandis que le contact auxiliaire 47 est commandé avec un certain retard.Ce retard est indépendant du sens de rotation du balancier 35.FIG. 6 shows an auxiliary contact capable of being associated or incorporated into a remote control switch according to FIG. 1 and using the same basic constituent elements. We see that the only difference consists in the insertion of an elastic blade 46 between the contact arm 39 and the balance 35. The tilting of the balance 35 is transmitted to the tilting auxiliary contact 47 after a first phase of deformation of the elastic blade 46 and the movement of the auxiliary contact 47 only intervenes thereafter, when the force of the elastic blade 46 manages to overcome the force provided by the leaf spring 23. The auxiliary contact 47 is coupled to a remote control switch according to the figure 1 and pendulums 35 are ordered simultaneously, either by a mechanical link or by electromechanical control. The tilting contact 14 immediately follows this movement to initiate the opening or closing of the remote control switch, while the auxiliary contact 47 is controlled with a certain delay. This delay is independent of the direction of rotation of the balance 35.

Le fonctionnement du télérupteur est décrit en détail dans le brevet précité et le lecteur pourra s'y reporter pour de plus amples détails. L'invention est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit.The operation of the remote control switch is described in detail in the aforementioned patent and the reader can refer to it for further details. The invention is of course in no way limited to the embodiment more particularly described.
