Abstract

The relay with an armature (3) tilted between two end positions so as to control two contacts at different positions along a contact carrying blade (8) has one arm of the armature resting on the arm (2') of the yoke (2) underneath the blade. Between the armature and the blade is a block (6) which lifts the blade when the armature is displaced. When lifted, a moving contact (9) is separated from a fixed contact (11) adjacent to the pad, and a moving contact (10) is connected to a fixed contact (12) at the free end. The pad incorporates a raised zone (14) across the end nearest the contacts so as to reduce the force required at the moment when the first contact pair is separated, and improve the switching action.

Description

La présente invention concerne un relais pourvu d'une armature magnétique agencée de manière à pouvoir basculer sur la culasse de la bobine magnétique entre deux positions extrêmes, armature qui actionne une lame de connexion pourvue de contacts et déformable en direction de lames de contact, par l'intermédiaire d'un appui pourvu d'une surface de support pour cette lame de connexion.The present invention relates to a relay provided with a magnetic armature arranged so as to be able to switch on the yoke of the magnetic coil between two extreme positions, armature which actuates a connection blade provided with contacts and deformable in the direction of contact blades, by by means of a support provided with a support surface for this connection blade.

On sait que, lorsque l'armature magnétique pivote de sa position de repos à sa position de travail, l'attaque de la surface de support de l'appui sur la lame de connexion se déplace, depuis un emplacement éloigné des contacts, vers ces contacts. Ceci a pour conséquence que, au début de la déformation de la lame de connexion, le bras de levier actif est le plus faible, de sorte que le système magnétique nécessite, initialement, une force importante, ce qui a des répercussions néfastes sur les temps de déformation et sur les temps de réponse du relais.It is known that, when the magnetic armature pivots from its rest position to its working position, the attack on the support surface of the support on the connection blade moves, from a location remote from the contacts, towards these contacts. This has the consequence that, at the beginning of the deformation of the connection blade, the active lever arm is the weakest, so that the magnetic system requires, initially, a large force, which has harmful repercussions on the times. deformation and response times of the relay.

l'objet- de la présente invention, pour un relais du type mentionné ci-dessus, est de créer des conditions pour adapter la force nécessaire à l'armature magnétique aux moments de l'attraction et de la réalisation du contact.  the object of the present invention, for a relay of the type mentioned above, is to create conditions for adapting the force necessary for the magnetic armature at the moments of the attraction and the making of the contact.

Selon l'invention, cet objectif est réalisé en ce que l'appui présente, dans sa surface de support, à l'extrémité proche des contacts, une saillie en forme de doigt dépassant à peine la surface de support. Cette saillie est pourvue, à cette fin, d'un bossage pouvant agir sur la lame de connexion et qui se termine, grâce à des surfaces courbes, par une de ses extrémité dans la surface de support et par l'autre extrémité dans la surface périphérique de l'appui.L'appui ainsi formé se trouve, au moment de l'attraction, grâce à la saillie, à un emplacement de la lame de connexion plus proche des contacts, pour réaliser avec une dépense d'énergie moindre, le processus de déformation de la lame de connexion de façon sure et puissante, et pour ensuite, lors d'une plus grande déformation de la lame de connexion, agir par l'intermédiaire du reste de la surface de support, et avec un bras de levier réduit, sur la lame de connexion. Ainsi, on obtient une force de mise en contact avec une déformation accélérée de la lame de connexion.According to the invention, this objective is achieved in that the support has, in its support surface, at the end close to the contacts, a finger-shaped projection barely exceeding the support surface. This projection is provided, for this purpose, with a boss which can act on the connection blade and which ends, thanks to curved surfaces, by one of its ends in the support surface and by the other end in the surface. support device. The support thus formed is, at the time of attraction, thanks to the projection, at a location of the connection blade closer to the contacts, to achieve with less energy expenditure, the process of deformation of the connection blade in a safe and powerful manner, and then, when the deformation of the connection blade is greater, act through the rest of the support surface, and with a lever arm reduced, on the connection blade. Thus, a contacting force is obtained with an accelerated deformation of the connection blade.

La figure 6 montre une portion de lame de connexion et un appui selon la figure 5, vus de profil.FIG. 6 shows a portion of the connection blade and a support according to FIG. 5, seen in profile.

Les références 1 et 2 désignent respectivement une bobine magnétique et une coulasse. Sur la branche libre 2' de la culasse 2 est agencée une armature magnétique 3 susceptible de pouvoir basculer et qui est soumise à une pression agissant dans la direction de la flèche 4, et produite, par exemple, par un ressort (non représenté). References 1 and 2 designate a magnetic coil and a slide respectively. On the free branch 2 'of the cylinder head 2 is arranged a magnetic armature 3 capable of being able to tilt and which is subjected to a pressure acting in the direction of the arrow 4, and produced, for example, by a spring (not shown).

L'armature magnétique 3 porte un appui 6 fixé par un téton 5 dans une cavité de l'armature magnétique 3.The magnetic frame 3 carries a support 6 fixed by a stud 5 in a cavity of the magnetic frame 3.

A l'appui 6 est associée une lame de connexion 8 contrainte et déformable, maintenue en 7, et pourvue de contacts 9 et 10; en position de repos d relais, la lame de connexion 8 peut etre amenée à coopérer avec la lame de contact 11 et en position de travail, avec la lame de contact 12.Support 6 is associated with a constrained and deformable connection blade 8, held at 7, and provided with contacts 9 and 10; in the relay rest position, the connection blade 8 can be brought to cooperate with the contact blade 11 and in the working position, with the contact blade 12.

Par rapport aux appuis connus 6 (figures 5 et 6) à surface plane 13 pour une lame de connexion 8, a surface de support 13 du relais selon l'invention présente à l'extrémité la plus proche des contacts 9, 10 une saillie en forme de doigt 14. La saillie 14, délimitée par un bossage 14' et des surfaces courbes 14", 14"', dépasse la surface de support d'environ 0,12 à 0,15 millimètres.Compared to the known supports 6 (FIGS. 5 and 6) with a flat surface 13 for a connection blade 8, a support surface 13 of the relay according to the invention has at the end closest to the contacts 9, 10 a protrusion in finger shape 14. The projection 14, delimited by a boss 14 'and curved surfaces 14 ", 14"', exceeds the support surface by approximately 0.12 to 0.15 millimeters.

Alors que, dans les relais pourvus des appuis connus 6 (voir les figures 5 et 6), ctest la partie de la surface de support, opposée aux contacts 9 et 10, qui au moment de l'attraction de l'armature magnétique 3, coopère avec la lame de connexion, ce qui par suite du court bras de levier L1 exige une force importante, en revanche, dans le cas de l'invention, l'appui 6 (figure 3) réalise, au moment de l'attraction de l'armature magnétique, une coopération de la saillie 14 avec la lame de connexion 8 à un endroit plus proche des contacts 9, 10 et donc avec un plus grand bras de levier L2. Il en résulte que, avec une dépense d'énergie moindre, le processus de déformation de la lame de connexion 8 est réalisé de façon sure. Lorsque la déformation de la lame de connexion 8 (figure 4) se poursuit, la surface de support 13 de l'appui 6 coopère ensuite avec la lame de connexion 8, de sorte que, avec un bras de levier
Il réduit, on obtient des accélérations de déformation accrues et des forces de contact sures sur la lame de connexion.
Whereas, in the relays provided with known supports 6 (see FIGS. 5 and 6), this is the part of the support surface, opposite to the contacts 9 and 10, which at the time of the attraction of the magnetic armature 3, cooperates with the connection blade, which as a result of the short lever arm L1 requires a large force, on the other hand, in the case of the invention, the support 6 (FIG. 3) achieves, at the time of the attraction of the magnetic armature, a cooperation of the projection 14 with the connection blade 8 at a location closer to the contacts 9, 10 and therefore with a larger lever arm L2. As a result, with a lower energy expenditure, the process of deformation of the connection blade 8 is carried out in a safe manner. When the deformation of the connection blade 8 (FIG. 4) continues, the support surface 13 of the support 6 then cooperates with the connection blade 8, so that, with a lever arm
It reduces, we obtain increased deformation accelerations and safe contact forces on the connection blade.
