Description
La présente invention concerne un commutateur électrique à action brusque selon le préambule de la revendication 1.The present invention relates to a snap action electric switch according to the preamble of claim 1.
Un commutateur de ce type a été décrit par exemple dans le brevet français No. 2.221 801, au nom de la Société DAV. Il présente l'avantage, grâce au basculement brusque de la plaquette porte-contact mobile dû à un effet de "dépassement de point mort", de permettre l'établissement et la coupure des courants de forte intensité (par exemple plusieurs ampères) malgré un faible encombrement de l'appareil.A switch of this type has been described for example in French patent No. 2,221,801, in the name of the company DAV. It has the advantage, thanks to the sudden tilting of the movable contact carrier plate due to an effect of "passing neutral", to allow the establishment and breaking of high intensity currents (for example several amps) despite a small footprint of the device.
De tels commutateurs sont largement utilisés dans l'industrie automobile pour la commande de nombreux circuits électriques. Pour la plupart des applications, ces commutateurs ont leurs deux positions (travail et repos) stables naturellement, grâce à l'effet de dépassement de point mort qui fait déclencher la plaquette porte-contact mobile vers l'une ou l'autre de ses positions et l'y maintient.Such switches are widely used in the automotive industry for controlling many electrical circuits. For most applications, these switches have their two positions (work and rest) which are naturally stable, thanks to the effect of exceeding neutral point which triggers the contact carrier plate. mobile to one or the other of its positions and keeps it there.
Il en résulte que la touche de commande, qui est généralement solidaire du levier basculant d'actionnement, doit être actionnée par l'opérateur dans un sens pour établir la position travail et, en sens inverse, pour revenir à la position de repos.It follows that the control button, which is generally integral with the tilting actuating lever, must be actuated by the operator in one direction to establish the working position and, in the opposite direction, to return to the rest position.
Depuis quelques années, on a recherché à simplifier la manoeuvre des commutateurs électriques, avec les commutateurs dits "push-push" dans lesquels l'opérateur pousse la touche de commande pour établir la position travail et pousse à nouveau la même touche pour revenir à la position repos.In recent years, we have sought to simplify the operation of electrical switches, with the so-called "push-push" switches in which the operator pushes the control key to establish the working position and pushes the same key again to return to the rest position.
Ces commutateurs "push-push" sont largement utilisés sur les appareils de télévision, de radio, etc., mais ne permettent pas en général la coupure de courants élevés, du fait que, le plus souvent, ils ne fonctionnent pas par action brusque.These "push-push" switches are widely used on television, radio, etc. devices, but generally do not allow the cutting of high currents, since, most often, they do not operate by snap action.
La présente invention a pour but de réaliser un commutateur à rupture brusque amélioré et à faible course.The present invention aims to achieve an improved snap switch and short stroke.
Selon l'invention, ce but est atteint par un commutateur électrique à action brusque, du type comprenant un boîtier, une touche de commande d'au moins un levier d'actionnement pivotant disposé dans ledit boîtier, une plaquette mince en métal élastique divisée, par deux fentes longitudinales, en trois bandes dont au moins une s'appuie et peut basculer sur un support entre deux positions dans l'une, au moins, desquelles un contact mobile porté par ladite plaquette est appuyé contre un contact fixe, ledit levier d'actionnement comportant au moins un doigt pour actionner ladite plaquette par appui glissant le long de l'une au moins des bandes de la plaquette, et caractérisé en ce que ladite plaquette peut se déplacer sur le support qui présente une partie de retenue et de guidage de ladite plaquette et en ce qu'au moins la bande sur laquelle le doigt est en appui comprend des moyens aptes, en coopération avec ledit doigt, à réaliser un déplacement dans un même plan de ladite plaquette avant de basculer.According to the invention, this object is achieved by an electric snap-action switch, of the type comprising a housing, a control key for at least one pivoting actuation lever disposed in said housing, a thin plate of divided elastic metal, by two longitudinal slots, in three bands of which at least one rests and can tilt on a support between two positions in at least one of which a movable contact carried by said plate is pressed against a fixed contact, said lever actuation comprising at least one finger for actuating said plate by sliding support along at least one of the bands of the plate, and characterized in that said plate can move on the support which has a retaining and guiding part of said wafer and in that at least the strip on which the finger is supported comprises suitable means, in cooperation with said finger, to make a movement in the same plane of said plate before tilting.
Un avantage de la présente invention réside dans le fait qu'on réalise un frottement entre les contacts électriques, avant leur séparation, ce qui permet d'avoir des contacts propres pour une meilleure conduction de l'électricité.An advantage of the present invention lies in the fact that there is friction between the electrical contacts, before their separation, which makes it possible to have clean contacts for better conduction of electricity.
La plaquette est guidée sur le support de façon à éviter un éventuel déplacement latéral de ladite plaquette et à obtenir toujours un appui répétitif entre les contacts électriques.The plate is guided on the support so as to avoid possible lateral displacement of said plate and always to obtain repetitive support between the electrical contacts.
D'autres avantages et caractéristiques apparaîtront à la lecture de la description d'un mode de réalisation de l'invention, ainsi que des dessins annexés sur lesquels :Other advantages and characteristics will appear on reading the description of an embodiment of the invention, as well as the appended drawings in which:
la figure 1 est une vue en coupe schématique du commutateur électrique selon un mode de réalisation de la présente invention.Figure 1 is a schematic sectional view of the electrical switch according to an embodiment of the present invention.
Les figures 2a à 2c sont des vues en perspective de la plaquette mince, suivant plusieurs modes préférés de réalisation.Figures 2a to 2c are perspective views of the thin wafer, according to several preferred embodiments.
La figure 3 est une vue en perspective du support de la plaquette mince, suivant un premier mode préféré de réalisation.Figure 3 is a perspective view of the support of the thin wafer, according to a first preferred embodiment.
La figure 4 est une vue en coupe du support représenté sur la figure 3.FIG. 4 is a sectional view of the support shown in FIG. 3.
La figure 5 est une vue en coupe du support suivant un autre mode préféré de réalisation.Figure 5 is a sectional view of the support according to another preferred embodiment.
Le commutateur électrique à action brusque comprend un boîtier 1 sur lequel est articulée une touche de commande 2 qui, sur la figure 1, est à double sens d'actionnement. La touche de commande pivote autour d'un axe de pivotement 3. Le commutateur électrique comprenant en conséquence, deux ensembles de commutation disposés de part et d'autre d'une lame fixe centrale 4 qui est en cuivre; la description qui suit est faite en référence à un des ensembles de commutation.The electric snap-action switch comprises a housing 1 on which is articulated a
L'ensemble de commutation comprend une plaquette mince en métal élastique 5, représentée en perspective sur les figures 2a à 2c, qui est divisée par deux fentes longitudinales 6, 7 en trois bandes 8, 9 et 10.The switching assembly comprises a thin plate of
La bande centrale 9 s'appuie sur un support 11, représenté en détail sur les figures 3 et 4 notamment, ledit support étant conducteur d'électricité et comprenant une partie 12 apte à être enfichée dans un socle 13 du boîtier et constituer une fiche de contact d'amenée de courant.The
La plaquette mince 5 porte, à une de ses extrémités deux contacts électriques mobiles 14 susceptibles de venir en appui sur un contact fixe supérieur électrique 15 prévu sur un retour 16 de la fiche centrale 4; ou sur un contact fixe électrique inférieur 17 porté par une fiche de contact d'amenée de courant 18. La bande centrale 9 comporte deux ouvertures, l'une 29 pour fixation sur le support 11 et l'autre 36 pour arrêter une éventuelle migration de graisse vers les contacts mobiles 14. L'ouverture 36 est de forme semi-circulaire, l'arête droite 36a étant située du côté des contacts mobiles 14.The
Les extrémités libres 19 et 20 des bandes latérales 8 et 10 sont légèrement recourbées (figure 2a) et constituent des premiers moyens permettant à ladite plaquette 5 de se déplacer dans un même plan avant son basculement, soit avant qu'un des contacts 14 ne vienne en appui sur le contact supérieur 15. Suivant une autre forme de réalisation (figure 2b), les bandes latérales 8 et 10 comportent à proximité de leurs extrémités 19 et 20, au moins une cambrure vers le haut 35 et lesdites cambrures et jouant le même rôle que les courbures 19′,20′ de la figure 2a. Suivant une autre forme de réalisation (figure 2c), les bandes latérales 8 et 10 comportent chacune, à proximité de l'extrémité 19, 20, au moins une rainure peu profonde 35′, qui permet également une translation de la plaquette 5 avant son basculement.The
Le support 11 comprend une première partie 12 constituant fiche de contact ou languette de connexion, une deuxième partie inclinée 21 et une troisième partie 22 qui peut être inclinée ou horizontale et parallèle à la partie 12, ainsi que cela est représenté sur la figure 4. A proximité de la jonction des parties 12 et 21, une ouverture 23 est ménagée dans la partie 12 et la languette de métal 24 ainsi réalisée est repliée dans un sens ou dans l'autre. La languette 24 constitue une butée qui vient en appui sur un fond 25 d'un passage 26 pour la partie 12 dans le socle 13, au-delà de la languette 24, le support 11 ne peut plus être retiré. L'enfichage est autorisé grâce à l'élasticité de la languette 24 qui vient se loger dans l'orifice 23 le temps nécessaire à la traversée du socle 13.The
La partie ou patte 22 est comprise entre deux petites zones d'appui 27 ménagées sur la partie 21, et comporte une encoche 28. La partie 22 passe à travers une ouverture 29 ménagée dans la bande centrale 9 de la plaquette mince 5. La bande centrale 9 repose sur les zones d'appui 27 qui constituent, avec l'ouverture 29, des moyens de support et de guidage pour la plaquette mince 5.The part or
L'encoche 28 a une double fonction. La première est de positionner correctement le support 11 dans le socle 13 du boîtier, au moyen d'un outil approprié qui est engagé dans ladite encoche. La deuxième est de ménager deux ailes 28a qui, après pliage dans un sens quelconque, empêchent la plaquette mince 5 de s'extraire hors du support lorsqu'on renverse le commutateur. De cette façon, on s'affranchit des tolérances très faibles quant aux dimensions de l'ouverture 29 de la plaquette, qui peut être surdimensionnée par rapport à la partie 22.The
Ainsi, la partie 22 constitue à la fois un moyen de guidage et de retenue pour la bande 9 de la plaquette 5.Thus, the
Suivant une autre forme de réalisation représentée sur la figure 5, le support 11 présente une deuxième partie 21′ qui est sensiblement perpendiculaire aux deux parties parallèles 12 et 22.According to another embodiment shown in FIG. 5, the
Le commutateur représenté sur la figure 1, comprend une pièce 30 en forme de U inversé qui est solidaire de la touche de commande 2 et qui, lors du pivotement pousse un levier 30′ comprenant deux doigts 31 dont les extrémités inférieures 32 sont en contact glissant sur les bandes latérales 8 et 10 de la plaquette 5. Les doigts 31 sont rappelés vers la position stable grâce à un ressort 33, en forme d'épingle à cheveux, monté entre lesdits doigts et le corps du boîtier 1. Lors du basculement de la touche de commande 2 autour de l'axe 3, les extrémités 32 des doigts 31 glissent sur les bandes latérales 8 et 10 jusqu'à ce qu'elles rencontrent les parties recourbées 19′ et 20′. A ce moment, et avant qu'ils n'aient dépassé le "point mort" ou plutôt le basculement de la plaquette 5, cette dernière est déplacée grâce à l'action des extrémités 32 sur les parties recourbées 19′ et 20′. Le contact inférieur 14 est donc déplacé sur le contact inférieur 17, provoquant ainsi un frottement entre les contacts 14 et 17 et par suite un nettoyage desdits contacts, ce qui assure une meilleure conduction de l'électricité circulant dans les fiches 12 et 18.The switch shown in Figure 1, comprises a
Dans une forme de réalisation préférée de l'invention, les contacts mobiles et fixes 14, 15 et 17 sont réalisés dans un alliage d'argent et d'oxyde de cadmium et la lame fixe centrale 4 est en cuivre.In a preferred embodiment of the invention, the movable and
