Ce but est atteint par un relais multiple tel qu'il est caractérisé dans la revendication 1.This object is achieved by a multiple relay as characterized in claim 1.

La figure 1 représente un relais multiple ; un support 1 en forme de U est constitué d'un socle 2 et de deux branches 3 et 3' ; sur le socle sont fixés un relais électromagnétique de commande 9, et des relais électromagnétiques 8 ; une barre commune 4, isolante, pivote autour d'un axe 5 fixé dans les branches 3 et 3' ; la barre commune 4 est située au-dessus du relais électromagnétique de commande 9 et des relais électromagnétiques 8, et comporte sur toute sa longueur deux barres conductrices 6 et 7 ayant respectivement une patte pliée, dite contact semi fixe, 10, 11, en regard de chaque relais électromagnétique. Un ressort de rappel, non représenté, permet de ramener la barre commune 4 en position de repos lorsqu'elle a pivoté. Chaque relais électromagnétique comporte un circuit magnétique 12, un élément mobile 13, une butée 14, des bornes 15 et 16 raccordées chacune respectivement à deux contacts portés par l'élément mobile ; un capot 17 protège l'ensemble des relais électromagnétiques.Figure 1 shows a multiple relay; a U-shaped support 1 consists of a base 2 and two branches 3 and 3 '; on the base are fixed an electromagnetic control relay 9, and electromagnetic relays 8; a common insulating bar 4 pivots about an axis 5 fixed in the branches 3 and 3 '; the common bar 4 is located above the electromagnetic control relay 9 and the electromagnetic relays 8, and comprises over its entire length two conductive bars 6 and 7 having respectively a folded tab, called semi-fixed contact, 10, 11, opposite of each electromagnetic relay. A return spring, not shown, makes it possible to return the common bar 4 to the rest position when it has pivoted. Each electromagnetic relay comprises a magnetic circuit 12, a mobile element 13, a stop 14, terminals 15 and 16 each connected respectively to two contacts carried by the mobile element; a cover 17 protects all of the electromagnetic relays.

La figure 2 est une vue selon la coupe II-II du relais multiple, coupe effectuée au niveau du relais électromagnétique de commande. Dans cette figure on trouve le socle 2, la barre commune 4 avec les barres conductrices 6 et 7.Figure 2 is a view along section II-II of the multiple relay, section made at the electromagnetic control relay. In this figure we find the base 2, the common bar 4 with the conductive bars 6 and 7.

Le relais électromagnétique de commande comprend une bobine 20 bobinée sur une carcasse 21, isolante, un circuit magnétique 22 ouvert en 23 et fixé sur le socle par une vis 24.The electromagnetic control relay comprises a coil 20 wound on an insulating carcass 21, a magnetic circuit 22 open at 23 and fixed to the base by a screw 24.

Au niveau du relais électromagnétique de commande, la barre commune 4 comporte un volet 25 muni d'une palette 26 en matériau magnétique, en regard de l'ouverture 23 du circuit magnétique. La barre commune 4 comporte à chaque extrémité une partie cylindrique 27 dans laquelle est engagé l'axe 5, permettant ainsi le pivotement de la barre commune ; lorsque le relais électromagnétique de commande est alimenté, la palette 26 est attirée et vient contre le circuit magnétique 22, ce qui entraîne le pivotement de la barre commune vers le haut. Une broche 28 est connectée à une extrémité de la bobine 20 ; le relais multiple est enfiché sur une carte de circuit imprimé 29.At the electromagnetic control relay, the common bar 4 comprises a flap 25 provided with a pallet 26 of magnetic material, opposite the opening 23 of the magnetic circuit. The common bar 4 has at each end a cylindrical part 27 in which the axis 5 is engaged, thus allowing the pivoting of the common bar; when the electromagnetic control relay is supplied, the pallet 26 is attracted and comes against the magnetic circuit 22, which causes the pivoting of the common bar upwards. A pin 28 is connected to one end of the coil 20; the multiple relay is plugged into a printed circuit board 29.

La figure 3 est une vue selon la coupe III-III du relais multiple, coupe effectuée au niveau d'un relais électromagnétique. Dans cette figure on retrouve le socle 2, la barre commune 4 avec les barres conductrices 6 et 7, et au niveau du relais électromagnétique un contact fixe 10 de la barre conductrice 6 et un contact fixe 11 de la barre conductrice 7. Le relais électromagnétique comporte une bobine 31 bobinée sur une carcasse 32, isolante, un circuit magnétique 12 ouvert en 33 et fixé sur le socle par une vis 34. Un élément mobile 13, isolant, est muni d'une palette 35, en matériau magnétique, en regard de l'ouverture 33 du circuit magnétique. L'élément mobile 13 est traversé par deux contacts que l'on appellera contacts mobiles dans la suite de la description ; un seul contact mobile 36 est représenté sur la figure, l'autre contact mobile étant derrière, comme on peut le voir sur la figure 1, chaque contact mobile étant double et constitué par exemple par deux fils comme cela est classique dans les relais électromagnétiques ; le contact mobile est enfiché dans le socle 2 et son extrémité constitue une broche 37. La barre commune étant en position repos, le relais électromagnétique de commande n'étant pas alimenté, l'extrémité supérieure du contact mobile 36 vient en regard d'un contact semi fixe 10 par exemple, l'extrémité de l'autre contact mobile venant en regard du contact semi fixe 11, chaque contact semi fixe 10 et 11 étant constitué, comme il a été dit, par une patte pliée des barres conductrices 6 et 7, respectivement.Figure 3 is a view along section III-III of the multiple relay, section made at an electromagnetic relay. In this figure we find the base 2, the common bar 4 with the conductive bars 6 and 7, and at the electromagnetic relay a fixed contact 10 of the conductive bar 6 and a fixed contact 11 of the conductive bar 7. The electromagnetic relay comprises a coil 31 wound on a carcass 32, insulating, a magnetic circuit 12 open at 33 and fixed to the base by a screw 34. A movable element 13, insulating, is provided with a pallet 35, made of magnetic material, opposite opening 33 of the magnetic circuit. The moving element 13 is crossed by two contacts which will be called movable contacts in the following description; a single movable contact 36 is shown in the figure, the other movable contact being behind, as can be seen in FIG. 1, each movable contact being double and constituted for example by two wires as is conventional in electromagnetic relays; the movable contact is inserted in the base 2 and its end constitutes a pin 37. The common bar being in the rest position, the electromagnetic control relay not being supplied, the upper end of the movable contact 36 comes opposite a semi-fixed contact 10 for example, the end of the other movable contact coming opposite the semi-fixed contact 11, each semi-fixed contact 10 and 11 being constituted, as has been said, by a folded tab of the conducting bars 6 and 7, respectively.

Au repos, relais électromagnétique non alimenté, l'élément mobile vient contre la butée 14 qui est par exemple une lame métallique enfichée dans le socle. Une broche 38 est connectée à une extrémité de la bobine 31. Le relais électromagnétique est enfiché sur la carte de circuit imprimé 29.At rest, electromagnetic relay not supplied, the movable element comes against the stop 14 which is for example a metal blade inserted in the base. A pin 38 is connected to one end of the coil 31. The electromagnetic relay is plugged into the printed circuit board 29.

L'extrémité supérieure de chaque contact mobile 36 étant en regard d'un contact semi fixe, 10 ou 11, au repos, il est nécessaire de faire pivoter la barre commune 4 pour dégager l'extrémité supérieure des contacts mobiles avant d'alimenter le relais électromagnétique afin d'attirer la palette 35 et par là même l'élément mobile 13.The upper end of each movable contact 36 being opposite a semi-fixed contact, 10 or 11, at rest, it is necessary to pivot the common bar 4 to release the upper end of the movable contacts before supplying the electromagnetic relay in order to attract the pallet 35 and thereby the movable element 13.

La figure 4 représente la connexion d'alimentation d'une barre conductrice, 6 par exemple, ayant une patte 40 sur laquelle est fixée une connexion 41, constituée par fil métallique, ou une lamelle métallique, enfichée dans le socle 8 et faisant office de ressort, l'extrémité de la connexion dépassant du socle constituant une broche 42. Lorsque le relais électromagnétique de commande est alimenté la barre commune 4 pivote vers le haut ; après suppression de l'alimentation du relais électromagnétique de commande la barre commune 4 reprend sa position de repos sous l'action de la connexion 41 qui joue le rôle d'un ressort de rappel ; bien entendu la barre conductrice 7 peut également avoir une connexion faisant office de ressort de rappel, cette connexion étant située par exemple à l'autre extrémité de la barre commune 4.FIG. 4 represents the supply connection of a conductive bar, for example 6, having a tab 40 on which is fixed a connection 41, constituted by metal wire, or a metal strip, inserted in the base 8 and acting as spring, the end of the connection projecting from the base constituting a pin 42. When the electromagnetic control relay is supplied, the common bar 4 pivots upwards; after removal of the supply from the electromagnetic control relay, the common bar 4 returns to its rest position under the action of the connection 41 which acts as a return spring; of course the conductive bar 7 can also have a connection acting as a return spring, this connection being situated for example at the other end of the common bar 4.

La figure 5 représente schématiquement les étapes successives de l'établissement en a, b, c, d, e, et de la libération en f, des contacts d'un relais électromagnétique 8 du relais multiple. Bien que l'on n'ait représenté qu'un contact semi fixe 10 de la barre commune et un contact mobile 36 du relais électromagnétique 8, il est bien entendu que le fonctionnement concerne les deux contacts semi fixes du relais électromagnétique qui sont solidaires de la barre commune, et les deux contacts mobiles qui sont solidaires de l'élément mobile du relais électromagnétique.FIG. 5 schematically represents the successive stages of the establishment in a, b, c, d, e, and of the release in f, of the contacts of an electromagnetic relay 8 of the multiple relay. Although only a semi fixed contact 10 of the common bar and a movable contact 36 of the electromagnetic relay 8 have been shown, it is understood that the operation relates to the two semi fixed contacts of the electromagnetic relay which are integral with the common bar, and the two movable contacts which are integral with the movable element of the electromagnetic relay.

A la figure 5a le relais multiple est en position repos ; le contact semi fixe 10 est en position basse, la bobine du relais électromagnétique de commande n'étant pas alimentée ; de même la bobine du relais électromagnétique 8 n'étant pas alimentée, le contact mobile 36 est en position repos.In FIG. 5a, the multiple relay is in the rest position; the semi-fixed contact 10 is in the low position, the coil of the electromagnetic control relay not being supplied; Similarly, the coil of the electromagnetic relay 8 is not supplied, the movable contact 36 is in the rest position.

A la figure 5b la bobine du relais électromagnétique de commande étant alimentée la barre commune pivote autour de son axe et le contact semi fixe 10 vient en position haute, dégageant ainsi l'extrémité supérieure du contact mobile 36.In FIG. 5b, the coil of the electromagnetic control relay being supplied, the common bar pivots about its axis and the semi-fixed contact 10 comes to the high position, thus freeing the upper end of the movable contact 36.

A la figure 5c, le contact semi fixe 10 étant en position haute la bobine du relais électromagnétique 8 est alimentée et le contact mobile 36 est attiré.In FIG. 5c, the semi-fixed contact 10 being in the high position, the coil of the electromagnetic relay 8 is supplied and the movable contact 36 is attracted.

A la figure 5d, l'alimentation de la bobine du relais électromagnétique de commande est coupée et le contact semi fixe 10 reprend sa position de repos.In FIG. 5d, the supply to the coil of the electromagnetic control relay is cut off and the semi-fixed contact 10 returns to its rest position.

A la figure 5e, l'alimentation de la bobine du relais électromagnétique 8 est coupée ; le contact mobile 36 n'étant plus attiré se déplace pour reprendre sa position de repos, mais le contact semi fixe étant en position repos, l'extrémité supérieure du contact mobile vient buter contre le contact semi fixe 10 ce qui établit le contact électrique entre les contacts semi fixe et mobile et assure un verrouillage mécanique dudit contact électrique qui ne, nécessite plus aucune alimentation du relais électromagnétique de commande ni du relais électromagnétique 8 pour son maintien ; bien entendu le déplacement du contact mobile est faible, de l'ordre de quelques dixièmes de millimètres, ce qui correspond à l'écart entre le contact semi fixe et le contact mobile dans le cas de la figure 5d.In FIG. 5e, the supply to the coil of the electromagnetic relay 8 is cut off; the movable contact 36 no longer being attracted moves to return to its rest position, but the semi fixed contact being in the rest position, the upper end of the movable contact abuts against the semi fixed contact 10 which establishes the electrical contact between the semi-fixed and mobile contacts and provides mechanical locking of said electrical contact which no longer requires any supply of the electromagnetic control relay or of the electromagnetic relay 8 to maintain it; of course, the displacement of the movable contact is small, of the order of a few tenths of a millimeter, which corresponds to the difference between the semi-fixed contact and the movable contact in the case of FIG. 5d.

La figure 5f représente la libération du contact électrique entre le contact semi fixe 10 -et le contact mobile 36. Pour cela la bobine du relais électromagnétique de commande est alimentée ; la barre commune pivote et le contact semi fixe 10 prend la position haute, libérant ainsi le contact mobile 36 qui reprend sa position de repos. L'alimentation de la bobine du relais électromagnétique de commande est alors supprimée et le contact semi fixe reprend sa position de repos ; on retrouve alors la position de la figure 5a.FIG. 5f represents the release of the electrical contact between the semi-fixed contact 10 and the movable contact 36. For this, the coil of the electromagnetic control relay is supplied; the common bar pivots and the semi-fixed contact 10 assumes the high position, thus releasing the movable contact 36 which returns to its rest position. The supply of the coil of the electromagnetic control relay is then removed and the semi-fixed contact returns to its rest position; we then find the position of Figure 5a.

La libération du contact électrique peut également être obtenue de la manière suivante, à partir de la figure 5e : on alimente la bobine du relais électromagnétique 8 ce qui entraîne l'attraction du contact mobile 36, et l'on retrouve la position de la figure 5d ; on alimente alors la bobine du relais électromagnétique de commande et le contact semi fixe 10 prend la position haute, dégageant ainsi le contact mobile 36 comme représenté figure 5c ; on coupe l'alimentation de la bobine du relais électromagnétique 8 et le contact mobile 36 revient en position de repos, comme représenté figure 5b où l'on retrouve la position de la figure 5f ; on coupe alors l'alimentation de la bobine du relais électromagnétique de commande et le contact semi fixe 10 revient en position de repos, comme représenté figure 5a.The release of the electrical contact can also be obtained in the following manner, from FIG. 5e: the coil of the electromagnetic relay 8 is supplied, which brings about the attraction of the movable contact 36, and the position of the figure is found again. 5d; the coil of the electromagnetic control relay is then supplied and the semi-fixed contact 10 takes the high position, thus releasing the movable contact 36 as shown in FIG. 5c; the supply to the coil of the electromagnetic relay 8 is cut off and the movable contact 36 returns to the rest position, as shown in FIG. 5b where the position of FIG. 5f is found; the supply to the coil of the electromagnetic control relay is then cut off and the semi-fixed contact 10 returns to the rest position, as shown in FIG. 5a.

Tant à l'établissement qu'à la libération du contact électrique les bobines du relais électromagnétique 8 et du relais électromagnétique de commande sont alimentées pendant le temps strictement flaire par lâ fermeture ou l'ouverture du contact électrique, le maintien du contact électrique ne nécessitant aucun courant.Both at the establishment and at the release of the electrical contact, the coils of the electromagnetic relay 8 and the electromagnetic control relay are supplied for the time strictly smelled by the closing or opening of the electrical contact, the maintenance of the electrical contact not requiring no current.

Dans l'application à un réseau de connexion spatial chacune des barres conductrices 6 et 7 représente une barre horizontale et chaque contact mobile d'un relais électromagnétique est relié à une barre verticale.In the application to a spatial connection network, each of the conductive bars 6 and 7 represents a horizontal bar and each movable contact of an electromagnetic relay is connected to a vertical bar.

Pour établir une communication téléphonique, il faut établir deux points de connexion, c'est-à-dire un contact électrique entre un contact mobile d'un relais électromagnétique et un contact semi fixe d'une barre conductrice, et un autre contact électrique entre un autre contact mobile dudit relais électromagnétique et un contact semi fixe de l'autre barre conductrice.To establish a telephone call, two connection points must be established, i.e. an electrical contact between a moving contact of an electromagnetic relay and a semi-fixed contact of a busbar, and another electrical contact between another movable contact of said electromagnetic relay and a semi-fixed contact of the other busbar.
