- a pressure spring in support, a pressure spring, a movable contact bridge, a central surface of which is placed opposite the bearing surface, and a U-shaped coupling stirrup, the parallel branches of which are provided with hooks and connected to a common cross member, surround the contact bridge to communicate a bearing force on fixed contacts by means of an elastic blade which is placed on this contact bridge and which has a central notch capable of cooperating with a rib of stirrup.
- Such holding devices are in particular used to effect elastic holding of the contact bridges of electromagnetic contactors.
- curved hooks of the stirrup engage on a movable turn placed at the end of the spring, while the common crosspiece is applied by means of an elastic blade on the surface of the contact bridge.
- this continuous crosspiece has a centering rib which cooperates with a notch for holding the blade elastic, it is not convenient to communicate by pressure to the central region of this blade, a deformation allowing the notch to escape from the rib, deformation which is necessary to operate the dismantling or the replacement of a bridge of contact.
- a stirrup has two branches which pass inside a contact pressure spring, and whose curved ends cooperate with a support washer intended to receive the turn spring mobile; this device does not allow an easy assembly insofar as this washer must be put in place when the spring is placed in the housing of the contact carrier, and that its introduction into this housing is done in a direction opposite to that which must take the stirrup to enter this same housing.
- the invention proposes to provide an elastic contact bridge holding device in which measures will be taken to facilitate disassembly of the contact bridge without altering the convenience of assembling the contact carrier in the factory.
- this result is achieved thanks to the fact that the cross member common to the two branches of the stirrup rests directly on the movable turn of the spring, while the hooks which are directed towards each other transversely by relative to the axis XX 'of the spring, and are separated by an interval, pass above the bearing surface.
- a contactor using the device according to the invention and visible in Figure 1 mainly comprises a body 1 in which is arranged an electromagnet 2 having a fixed yoke 3, a coil 4 and a movable armature 5.
- the latter is associated with the lower part 6 of a contact carrier 7 whose movements, in a plane PP ', are guided by means not shown.

- the examination of FIG. 1 shows that the cross member 27 of the metal stirrup 28 is placed in the vicinity of the frame 5; it is therefore necessary to interpose between these two pieces of isolation means to prevent the birth of leakage currents or arcs which would tend to be established between two neighboring switches via the frame.
- the means used are represented by an isolation piece 50, see also FIG. 2, a boss 51 of which penetrates into the lower portion 31 of the housing 18, which rests on the frame, and which is capable of serving as a stop. at crossbar 27.

Abstract
Description
La présente invention se rapporte à un dispositif de maintien élastique d'un pont de contact comprenant un porte-contact isolant, pourvu d'une colonne présentant extérieurement sur son sommet une surface d'appui sur laquelle s'ouvre un logement interne apte à recevoir en appui un ressort de pression, un pont de contact mobile dont une surface centrale est placée en regard de la surface d'appui, et un étrier d'accouplement en forme de U dont les branches parallèles,-pourvues de crochets et reliées à une traverse commune, entourent le pont de contact pour lui communiquer une force d'appui sur des contacts fixes par l'intermédiaire d'une lame élastique qui est placée sur ce pont de contact et qui présente une encoche centrale apte à coopérer avec une nervure de l'étrier.The present invention relates to a device for resiliently maintaining a contact bridge comprising an insulating contact carrier, provided with a column having externally on its top a bearing surface on which an internal housing capable of receiving opens. in support, a pressure spring, a movable contact bridge, a central surface of which is placed opposite the bearing surface, and a U-shaped coupling stirrup, the parallel branches of which are provided with hooks and connected to a common cross member, surround the contact bridge to communicate a bearing force on fixed contacts by means of an elastic blade which is placed on this contact bridge and which has a central notch capable of cooperating with a rib of stirrup.
De tels dispositifs de maintien sont en particulier utilisés pour effectuer un maintien élastique des ponts de contact de contacteurs électromagnétiques. Dans un dispositif de maintien de pont de contact connu, répondant à la constitution générale mentionnée ci-dessus, des crochets recourbés de l'étrier s'engagent sur une spire mobile placée à l'extrémité du ressort, tandis que la traverse commune est appliquée par l'intermédiaire d'une lame élastique sur la surface du pont de contact.Such holding devices are in particular used to effect elastic holding of the contact bridges of electromagnetic contactors. In a known contact bridge holding device, responding to the general constitution mentioned above, curved hooks of the stirrup engage on a movable turn placed at the end of the spring, while the common crosspiece is applied by means of an elastic blade on the surface of the contact bridge.
Comme cette traverse continue présente une nervure de centrage qui coopère avec une encoche de maintien de la lame élastique, il n'est pas commode de communiquer par pression à la région centrale de cette lame, une déformation permettant à l'encoche d'échapper à la nervure, déformation qui est nécessaire pour opérer le démontage ou la rechange d'un pont de contact.As this continuous crosspiece has a centering rib which cooperates with a notch for holding the blade elastic, it is not convenient to communicate by pressure to the central region of this blade, a deformation allowing the notch to escape from the rib, deformation which is necessary to operate the dismantling or the replacement of a bridge of contact.
Dans un autre dispositif de maintien élastique de pont de contact connu, un étrier présente deux branches qui passent à l'intérieur d'un ressort de pression de contact, et dont les extrémités recourbées coopèrent avec une rondelle d'appui destinée à recevoir la spire mobile du ressort ; ce dispositif ne permet pas un montage aisé dans la mesure où cette rondelle doit être mise en place lorsque le ressort est placé dans le logement du porte-contact, et que son introduction dans ce logement se fait dans une direction opposée à celle que doit prendre l'étrier pour pénétrer dans ce même logement.In another known elastic contact bridge holding device, a stirrup has two branches which pass inside a contact pressure spring, and whose curved ends cooperate with a support washer intended to receive the turn spring mobile; this device does not allow an easy assembly insofar as this washer must be put in place when the spring is placed in the housing of the contact carrier, and that its introduction into this housing is done in a direction opposite to that which must take the stirrup to enter this same housing.
L'invention se propose de fournir un dispositif de maintien élastique de pont de contact dans lequel des mesures seront prises pour faciliter le démontage du pont de contact sans altérer la commodité de l'assemblage du porte-contact en usine.The invention proposes to provide an elastic contact bridge holding device in which measures will be taken to facilitate disassembly of the contact bridge without altering the convenience of assembling the contact carrier in the factory.
Selon l'invention, ce résultat est atteint grâce au fait que la traverse commune aux deux branches de l'étrier s'appuie directement sur la spire mobile du ressort, tandis que les crochets qui sont dirigés l'un vers l'autre transversalement par rapport à l'axe XX' du ressort, et sont séparés par un intervalle, passent au-dessus de la surface d'appui.According to the invention, this result is achieved thanks to the fact that the cross member common to the two branches of the stirrup rests directly on the movable turn of the spring, while the hooks which are directed towards each other transversely by relative to the axis XX 'of the spring, and are separated by an interval, pass above the bearing surface.

Un contacteur faisant appel au dispositif selon l'invention et visible à la figure 1, comprend principalement un corps 1 dans lequel est' disposé un électro-aimant 2 ayant une culasse fixe 3, une bobine 4 et une armature mobile 5. Cette dernière est associée à la partie inférieure 6 d'un porte-contact 7 dont les mouvements, dans un plan PP', sont guidés par des moyens non représentés. La partie supérieure 8 du porte-contact comprend plusieurs colonnes parallèles 9, 10, 11 identiques portant chacune un pont de contact tel que 12, voir aussi la figure 2..A contactor using the device according to the invention and visible in Figure 1, mainly comprises a
Ce pont de contact 12 coopère avec des contacts fixes 13, 14 pour former un interrupteur de puissance 15 qui est logé dans une alvéole 16 appartenant à une série d'alvéoles parallèles disposées dans un boîtier d'isolement 17 fixé sur le corps.This
La colonne 9 est traversée par un logement 18 qui s'étend sur sa longueur et qui débouche par une ouverture supérieure 19 sur une surface d'appui 10 et par une ouverture inférieure 21 dans une cavité 22 qui reçoit l'armature. Ce logement 18 possède deux largeurs tranversales de façon à former un épaulement 23 qui est dirigé vers la cavité 22 et sur lequel s'appuie une spire fixe 24 d'un ressort de pression de contact 25 ; la spire mobile 26 de ce ressort s'appuie à son tour sur une traverse 27 d'un étrier 28 ayant deux branches parallèles 29, 30 qui lui confèrent la forme générale d'un U, voir figure 2.The
L'étrier 28 se trouve placé en partie dans une portion inférieure 31 du logement 18 qui reçoit le ressort et en partie dans une portion supérieure 32 de ce logement.The stirrup 28 is located partly in a
Deux extrémités supérieures 33, 34 de ces branches, qui sont placées au-dessus de la surface d'appui 20 présentent chacune un crochet 35, respectivement 36, qui est orienté vers l'autre crochet ; un intervalle 60 sépare les extrémités des crochets en regard.Two
Le pont de contact 12 qui est représenté à la figure 1, dans la position de fermeture de l'interrupteur 15 prend la forme d'une cuvette ayant un fond 37, deux parois latérales 38, 39 et deux cornes d'arc 40, 41 les pastilles de contact mobile 42, 43 sont disposées sur la surface extérieure du fond 37, tandis que le volume intérieur 44 de la cuvette reçoit une lame élastique 45. Cette lame élastique possède deux extrémités 46, 47 qui s'appuient sur le fond au voisinage des cornes d'arc, et une région centrale bombée 48 qui présente une encoche 49.The
Le pont de contact 12 est placé entre les branches 29, 30 de l'étrier, voir la figure 2, de façon telle que les crochets 35, 36 s'engagent dans l'encoche 49 de la lame élastique ; une force de pression de contact développée par la compression du ressort 25 est donc transmise au pont de contact 12 par l'étrier 28 et par la lame élastique 45. L'examen de la figure 1 montre que la traverse 27 de l'étrier métallique 28 se trouve placée au voisinage de l'armature 5 ; il est donc nécessaire d'intercaler entre ces deux pièces des moyens d'isolement pour prévenir la naissance de courants de fuite ou d'arcs qui tendraient à s'établir entre deux interrupteurs voisins par l'intermédiaire de l'armature.The
Les moyens utilisés sont représentés par une pièce d'isolement 50, voir aussi la figure 2, dont un bossage 51 pénètre dans la portion inférieure 31 du logement 18, qui s'appuie sur l'armature, et qui est susceptible de servir de butée à la traverse 27.The means used are represented by an
Lorsque le pont de contact est en place et que l'interrupteur est ouvert, voir figure 5, la région centrale 52 du fond 37 du pont de contact est appliqué contre la surface d'appui 20 par le ressort de pression 25, et la traverse 27 n'entre pas en contact avec la pièce d'isolement 50, 51.When the contact bridge is in place and the switch is open, see FIG. 5, the
Le démontage d'un pont de contact 12- peut s'effectuer par exemple lorsque le pont de contact est appuyé sur les contacts fixes.The disassembly of a contact bridge 12- can be carried out for example when the contact bridge is pressed on the fixed contacts.
Dans ce but, une pression dans le sens G est exercée entre les crochets et dans l'intervalle 60 à l'aide d'un outil simple sur la région centrale de la lame élastique 45 (et en particulier sur le fond 57 de la rainure 49) pour déformer cette lame et permettre à cette rainure d'échapper aux crochets ; l'évacuation du pont de contact est ensuite opérée par une poussée latérale exercée en direction F.For this purpose, pressure in the direction G is exerted between the hooks and in the
Cette action qui est facilitée par l'existence de l'intervalle 60 entre les deux crochets 35, 36, voir en particulier la figure 3, est donc extrêmement aisée, car l'outil ne peut glisser latéralement en raison de sa coopération latérale et transversale avec les bords des crochets et avec la rainure.This action which is facilitated by the existence of the
Lorsque le pont de contact 12 et sa lame 45 ont été séparés du porte-contact 7, par exemple pour effectuer un remplacement, les crochets 35, 36 ne trouvent plus d'appui sur la lame et la traverse 27 s'appuie alors sur la pièce d'isolement 50 de façon telle qu'une distance a sépare ces crochets de la surface d'appui, voir la figure 6.When the
Cette mesure permet de remettre très aisément en place un pont de contact neuf en le glissant, avec sa lamme élastique, dans la. surface comprise entre les branches de l'étrier et le dessous des crochets.This measure makes it possible to very easily replace a new contact bridge by sliding it, with its elastic lamina, into the. area between the legs of the stirrup and the underside of the hooks.
Lorsque l'on effectue en usine l'équipement du porte-contact, l'armature 5 n'est pas encore associée à la cavité inférieure 22 du porte-contact, un ressort et un étrier devront être d'abord montés dans chaque logement.When the equipment of the contact carrier is carried out in the factory, the
Cette opération est grandement facilitée par la présence de la traverse dans la région inférieure de l'étrier, car en raison de sa forme plate, on peut disposer cet étrier et le ressort en équilibre vertical sur la pièce d'isolement, elle-même disposée sur l'armature, voir à la figure 6, et opérer leur introduction dans le logement par un mouvement de descente vertical J du porte-contact.This operation is greatly facilitated by the presence of the cross member in the lower region of the stirrup, because due to its flat shape, this stirrup and the spring can be placed in vertical equilibrium on the isolation piece, itself arranged. on the frame, see Figure 6, and operate their introduction into the housing by a vertical downward movement J of the contact carrier.
Si le montage s'effectue avec un porte-contact retourné, l'introduction de l'étrier et du ressort de pression dans le logement s'effectue par gravité dans le sens L, voir figure 2, la pièce d'isolement et l'armature étant ensuite introduits dans le logement et respectivement, dans la cavité, pour être finalement ensuite fixées dans cette cavité, par exemple à l'aide de goupilles telles que 56.If the assembly is carried out with an inverted contact carrier, the insertion of the caliper and the pressure spring into the housing takes place by gravity in direction L, see figure 2, the isolation piece and the reinforcement then being introduced into the housing and respectively into the cavity, to be finally then fixed in this cavity, for example using pins such as 56.
En raison des échauffements auxquels sont soumis le pont de contact et l'étrier, au cours d'une utilisation répétée de l'interrupteur, on peut craindre que les crochets s'écartent. en raison de déformations des branches de l'étrier. Pour prévenir cet inconvénient, on a donné à la surface supérieure du fond 57 de l'encoche 49 de la lame élastique 45, la forme d'un V très ouvert dans le plan PP', voir la figure 3.Because of the overheating to which the contact bridge and the clamp are subjected, during repeated use of the switch, it is feared that the hooks will move apart. due to deformations of the stirrup branches. To prevent this drawback, the upper surface of the
Les deux crochets qui présentent eux-mêmes une forme en V apte à coopérer avec l'encoche 49 pour opérer un maintien latéral du pont de contact dans le sens G, comportent chacun une arête inclinée 58 qui coopère avec le fond 57 de l'encoche.The two hooks which themselves have a V shape capable of cooperating with the
En raison de la direction de cette inclinaison, et par coopération entre cette arête et ce fond, une composante de la force du ressort de pression tend à rapprocher les crochets l'un vers l'autre, ce qui évite l'inconvénient mentionné ci-dessus.Due to the direction of this inclination, and by cooperation between this edge and this bottom, a component of the force of the pressure spring tends to bring the hooks towards each other, which avoids the drawback mentioned above. above.
