Definitions

  • the present invention relates to improvements to the push buttons contact breaker.
  • Such a push button allows, during its depression, to modify the electrical state of a line either permanently or temporarily, the modification ceasing as soon as the action on the control member is released.
  • the functions described above are obtained by the combination of two members namely a connector, stable or unstable, and a pusher constituting the control member of the assembly.
  • Such an assembly occupies a large volume and does not lend itself to the establishment of a light device to identify, for example, the location of the pusher, in other words, it is very difficult to achieve a light pusher .
  • the design of existing devices has shown that in case of failure of the lighting system it was necessary to replace the assembly.
  • Document DE 199954098 discloses a pushbutton contactor breaker comprising a pusher provided with a tail carrying a contact member, immobilized in rotation relative to said tail and held between two springs, said member being movable axially between two pairs of tiered contacts.
  • the means used to prevent rotation of the pusher relative to the body carrying the contacts are complicated and unreliable, the various elements making up the push button can be easily dismantled by an unauthorized person.
  • the button contact breaker of the invention which overcomes these disadvantages, comprises a closed body, at one of its ends, by an insulating base and, at the other, by a pusher, said base comprising two pairs of electrical contacts between each of which is disposed a contact member, said push button being characterized in that the contact member is guided on two candles of the base whose axes extend parallel to that of the pusher, said member being movable, in one direction, under the action of a spring, in a known manner and, in the other, under the action of said pusher.
  • the device consists of a body 1, preferably cylindrical, closed at one of its ends by a base 2 and at the other by a pusher 3.
  • the base 2 made of an insulating material, comprises two pairs of electrical contacts 4 and 5, angularly and axially offset relative to the body 1.
  • the base 2 is used to guide a connector plate 6 held in a stable position under the action of a spring 7 and can be moved during the depression of the pusher 3.
  • the contacts 4 and 5 are embodied by the screw heads, screwed into the base 2 and to which contacts the electrical conductors (not shown) are connected.
  • the plate 6 In the rest position, the plate 6 is applied under the heads of the screws under the action of the spring 7, said heads constituting members limiting the displacement of said plate or connecting member.
  • the pusher 3 is held by a spring 8, whose force is less than that of the spring 7.
  • This spring has a dual function, it can absorb dimensional variations that may occur during machining components and maintain the inner end of the pusher at a distance from the upper face of the plate 6. In this way, the user better perceives its action on the pusher.
  • the base 2 has two candles 9 guiding the plate 6 whose axes extend parallel to that of the pusher.
  • the bodies of the screws, the heads of which form the contacts 4 pass axially through the candles 9.
  • the base 2 serves to support the sleeve 10, a light source 11 screwed axially into said base (the power cables are not shown).
  • the sleeve 10 passes freely through the plate 6 to extend into the internal cavity 3a of the pusher which is advantageously made of a transparent or translucent material.
  • other means than the screwing can be used to maintain the sleeve 10.
  • the means used to fix the sleeve (10) are accessible from outside the body and that the withdrawal or the establishment of a light source does not influence the operation of the push button.

Description

  • La présente invention est relative à des perfectionnements aux boutons-poussoirs rupteur conjoncteur.
  • Un tel bouton-poussoir permet, lors de son enfoncement, de modifier l'état électrique d'une ligne soit de façon permanente soit de façon provisoire, la modification cessant dès que l'on relâche l'action sur l'organe de commande.
  • Généralement, les fonctions décrites ci-dessus sont obtenues par l'association de deux organes à savoir un : connecteur, stable ou instable, et un poussoir constituant l'organe de commande de l'ensemble.
  • Un tel ensemble occupe un volume important et ne se prête pas à la mise en place d'un dispositif lumineux permettant de repérer, par exemple, l'emplacement du poussoir, en d'autres termes, il est très difficile de réaliser un poussoir lumineux. De plus, la conception des dispositifs existants a montré qu'en cas de défaillance du système lumineux il fallait, remplacer l'ensemble.
  • Par de document DE 199954098 on connaît un bouton-poussoir rupteur conjoncteur comportant un poussoir pourvu d'une queue portant un organe de contact, immobilisé en rotation par rapport à ladite queue et maintenu entre deux ressorts, ledit organe étant mobile axialement entre deux paires de contacts étagées. Les moyens utilisés pour empêcher la rotation du poussoir par rapport au corps portant les contacts sont compliqués et peu fiables, les divers éléments composant le bouton-poussoir pouvant être facilement démontés par une personne non autorisée.
  • Le bouton-poussoir rupteur conjoncteur de l'invention, qui remédie à ces inconvénients, comporte un corps obturé, à l'une de ses extrémités, par une embase isolante et, à l'autre, par un poussoir, ladite embase comportant deux paires de contacts électriques entre chacune desquelles est disposé un organe de contact, ledit bouton-poussoir étant caractérisé en ce que l'organe de contact est guidé sur deux chandelles de l'embase dont les axes s'étendent parallèlement à celui du poussoir, ledit organe étant mobile, dans un sens, sous l'action d'un ressort, d'une façon connue et, dans l'autre, sous l'action dudit poussoir.
  • La présente invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif, seulement, sur lesquels:
    • la figure 1 est une vue en coupe d'un bouton-poussoir conforme à l'invention ;
    • la figure 2 est une vue en coupe effectuée selon la ligne ll-ll de la figure 1,
    • la figure 3 est une vue en coupe effectuée selon la ligne lll-lll de la figure 1, le poussoir étant enfoncé ;
    • la figure 4 est une vue, analogue à la figure 3, limitée à la représentation de l'embase et montrant la possibilité d'utiliser un système d'éclairage indépendant.
  • En se reportant aux dessins, on voit que le dispositif se compose d'un corps 1, de préférence cylindrique, obturé à l'une de ses extrémités par une embase 2 et à l'autre par un poussoir 3.
  • L'embase 2, réalisée en un matériau isolant, comporte deux paires de contacts électriques 4 et 5, décalées angulairement et axialement par rapport au corps 1.
  • L'embase 2 est utilisée pour assurer le guidage d'une plaque connectrice 6 maintenue en position stable sous l'action d'un ressort 7 et pouvant être déplacée lors de l'enfoncement du poussoir 3.
  • Pratiquement, les contacts 4 et 5 sont matérialisés par les têtes de vis, vissées dans l'embase 2 et auxquels contacts les conducteurs électriques (non représentés) sont raccordés.
  • En position de repos, la plaque 6 est appliquée sous les têtes des vis sous l'action du ressort 7, lesdites têtes constituant des organes limitant le déplacement de ladite plaque ou organe de connexion.
  • Il est à noter que le poussoir 3 est maintenu par un ressort 8, dont la force est inférieure à celle du ressort 7. Ce ressort a une double fonction, il permet d'absorber les variations de dimension pouvant se produire lors de l'usinage des constituants et de maintenir l'extrémité interne du poussoir à une certaine distance de la face supérieure de la plaque 6. De cette façon, l'usager perçoit mieux son action sur le poussoir.
  • L'embase 2 présente deux chandelles 9 de guidage de la plaque 6 dont les axes s'étendent parallèlement à celui du poussoir. De préférence les corps des vis, dont les têtes forment les contacts 4, traversent axialement les chandelles 9.
  • Comme cela ressort de la figure 4, l'embase 2 sert de support à la douille 10, d'une source lumineuse 11, vissée axialement dans ladite embase (les câbles d'alimentation ne sont pas représentés). La douille 10 traverse librement la plaque 6 pour s'étendre jusque dans la cavité interne 3a du poussoir qui est avantageusement réalisé en une matière transparente ou translucide. Bien entendu, d'autres moyens que le vissage peuvent être utilisés pour assurer le maintien de la douille 10.
  • Il est à noter que les moyens utilisés pour fixer la douille (10) sont accessibles de l'extérieur du corps et que le retrait, ou la mise en place, d'une source lumineuse n'influence pas le fonctionnement du bouton-poussoir.
