Abstract

Relais électromagnétique (1) comprenant un circuit magnétique (10) formé par une culasse (11), un aimant permanent (20) destiné à créer un flux magnétique (Øu) de polarisation, une armature mobile (40) montée à coulissement axial, une bobine (50) destinée à engendrer un flux magnétique (Øc) de commande opposé au premier flux (Øu) de polarisation, un ressort (60) de rappel pour actionner l'armature mobile (40) vers la position de déclenchement. Le relais comprenant aussi un poussoir extérieur (70) de déclenchement lié à l'armature mobile (40) par une liaison coulissante, le déplacement dudit poussoir par rapport à la dite armature étant réalisé entre une première position d'extension (d1) et une seconde position de compression (d2) et comprenant des moyens élastiques (71) exerçant sur le poussoir extérieur (70) et l'armature mobile (40) une force de maintien (FM) destinée maintenir l'armature mobile (40) vis à vis du poussoir extérieur (70) dans la position d'extension (d1).Electromagnetic relay (1) comprising a magnetic circuit (10) formed by a yoke (11), a permanent magnet (20) intended to create a magnetic flux (Øu) of polarization, a movable armature (40) mounted to slide axially, a coil (50) intended to generate a magnetic control flux (Øc) opposite to the first polarization flux (Øu), a return spring (60) for actuating the movable armature (40) towards the trigger position. The relay also comprising an external triggering pusher (70) linked to the movable armature (40) by a sliding connection, the displacement of said pusher with respect to said armature being carried out between a first extension position (d1) and a second compression position (d2) and comprising elastic means (71) exerting on the external pusher (70) and the movable frame (40) a holding force (FM) intended to keep the movable frame (40) vis-à-vis of the outer plunger (70) in the extended position (d1).
