   La présente invention est relative à des perfectionnements apportés aux relais électriques en vue d'une part de permettre le passage d'un ampèrage supérieur à celui obtenu normalement,et d' autre part d'obtenir une rupture de contact plus brusque et par suite une préservation meilleure des points de contact. 



   Dans ce   but,l    la came de rupture entrainée par l'attraction de l'électro-aimant sur son noyau est pourvue de plusieurs dents, disposées de telle sorte que l'intervalle entre deux dents successives correspond à chaque course aller et retour du noyau. 



   2  les plaques de contact portées par la came dentée n'offrent pas,une surface plane aux frottoirs, mais bien une surface inclinée. 



   Le dessin annexé à ce mémoire montre, à titre d'exemple uniquement, un mécanisme de relai conforme à l'invention. Dans ce dessin:
Fig.l est une vue en élévation de face du relai,
Fig.2 est une vue latérale,une des cloisons du boitier enlevée,et
Fig.3 est une coupe par A-B dans une plaque de contact de la came dentée. 



   Comme le montre le dessin, sur un axe 1 disposé transversalement dans le noyau 2 de l'élestro-aimant 3 peuvent pivoter deux lames en ébonite 4 supportant à leur autre extrémité une tige 5 guidée de part et d'autre dans des échancrures 7 prévues dans les cloisons verticales parallèles 6 du boitier du relai. 



   D'autre part sur un axe 8 monté excentriquement par rapport au noyau 2 de l'électro-aimant est monté un disque 9,remplaçant 

 <Desc/Clms Page number 2> 

 la came ordinaire, et présentant plusieurs dents ou becs 10, quatre dans le casprésent. Le disque 9 est pourvu sur chacune de ses faces d'une plaque conductrice 11 sur laquelle peut grimper,pour établir le contact, un frottoir 12 relié chacun à une borne 13 montée sur chaque cloison 6 du boitier.Les deux plaques 11 pourraient évidemment être remplacées par une seule plaque encastrée dans le disque 9 et saillant de part et d'autre de ce dernier. 



   Dans la position du relai représentée au dessin, la bobiné de 1'électro-aimant   n'est   parcourue par aucun courant,et son noyau 2 repose sur le disque 9; de plus les frottoirs 12 sont hors de contact avec leus plaques conductrices 11 de ce dernier. Dès que le courant passe dans la bobine 3',son noyau 2 se trouve attiré vers le haut et par ses lames   4   il exerce une traction sur la   ti-   ge 5, qui accroche une dent 10 du disque 9 et force ainsi ce   de r-   nier à pivoter autour de son axe 8. En même temps les frottoirs 12 grimpent sur les plaques conductrices 11 et le circuit électriqu se trouve fermé. La rupture du courant dans la bobine 3 ramène, sous le poids du noyau 2,la tige 5,guidée dans les échancrures 7 des cloisons 6,sous la dent suivante du disque 9. 



   Par suite de la répétition accélérée des enclenchements résultant de la multiplicité des dents 10,dont est pourvu le disque 9, il est ainsi possible de laisser passer un ampèrage supérieur à celui obtenu dans les relais de construction habituelle. 



   Enfin,comme le montre la fig.3, les plaques conductrices 11 n'ont pas une épaisseur constante,mais elles présentent une   certai-   ne inclinaison,de telle façon que les frottoirs 12 grimpent plus   aisément sur elles ; rupture du contact sera dlautant plus brus-   que et les points de contact seront mieux préservé s.

  Albert NOËL INVENTION PATENT,
23, avenue Sluysman, Grivegnée.
 EMI1.1
 P]) R1! 'EOTION! # LV # NTS TO ELECTRIC HELAIS.



   The present invention relates to improvements made to electrical relays with a view on the one hand to allowing the passage of an amperage greater than that obtained normally, and on the other hand to obtain a more abrupt contact break and consequently a better preservation of contact points.



   For this purpose, the rupture cam driven by the attraction of the electromagnet on its core is provided with several teeth, arranged so that the interval between two successive teeth corresponds to each outward and return stroke of the core .



   2 the contact plates carried by the toothed cam do not provide a flat surface for the wipers, but an inclined surface.



   The drawing appended to this specification shows, by way of example only, a relay mechanism according to the invention. In this drawing:
Fig.l is a front elevational view of the relay,
Fig. 2 is a side view, one of the partitions of the box removed, and
Fig. 3 is a section through A-B in a contact plate of the toothed cam.



   As shown in the drawing, on an axis 1 arranged transversely in the core 2 of the solenoid 3 can pivot two rubber blades 4 supporting at their other end a rod 5 guided on either side in the notches 7 provided. in the parallel vertical partitions 6 of the relay box.



   On the other hand on an axis 8 mounted eccentrically with respect to the core 2 of the electromagnet is mounted a disc 9, replacing

 <Desc / Clms Page number 2>

 the ordinary cam, and having several teeth or nozzles 10, four in the present case. The disc 9 is provided on each of its faces with a conductive plate 11 on which can climb, in order to establish contact, a friction plate 12 each connected to a terminal 13 mounted on each partition 6 of the case. The two plates 11 could obviously be replaced by a single plate embedded in the disc 9 and projecting on either side of the latter.



   In the position of the relay shown in the drawing, the coil of the electromagnet is not traversed by any current, and its core 2 rests on the disc 9; in addition, the rubbers 12 are out of contact with the conductive plates 11 of the latter. As soon as the current passes through the coil 3 ', its core 2 is drawn upwards and by its blades 4 it exerts a traction on the rod 5, which catches a tooth 10 of the disc 9 and thus forces it to r - deny to pivot around its axis 8. At the same time the rubbers 12 climb on the conductive plates 11 and the electrical circuit is closed. The breaking of the current in the coil 3 brings, under the weight of the core 2, the rod 5, guided in the notches 7 of the partitions 6, under the next tooth of the disc 9.



   As a result of the accelerated repetition of the interlockings resulting from the multiplicity of teeth 10, with which the disc 9 is provided, it is thus possible to allow a higher amperage to pass than that obtained in relays of usual construction.



   Finally, as shown in FIG. 3, the conductive plates 11 do not have a constant thickness, but they have a certain inclination, so that the rubbers 12 climb more easily on them; contact breakage will be all the more abrupt and the contact points will be better preserved.
