    摘要: The present invention relates to a direct current relay and, more specifically, to a direct current relay having a mover assembly having improved contact pressure. A direct current relay according to an aspect of the present invention, comprising: a pair of fixed contactors and a movable contactor which is moved up and down by an actuator to come into contact with or be separated from the pair of fixed contactors, comprises: a mover support disposed below the movable contactor and connected to the actuator by a shaft; a mover holder disposed above the movable contactor and fixed to the mover support; an upper yoke and a lower yoke disposed above and below the movable contactor to generate an electromagnetic force, respectively; and a contact pressure spring disposed between the lower yoke and the mover support, wherein the upper yoke and the lower yoke form a magnetic path to offset an electron repulsive force generated between the fixed contactors and the movable contactor.

    摘要: Relais électromécanique comprenant une bobine de commande (5), un noyau magnétique (2), une armature mobile (3) ayant une face active orientée en regard d'une extrémité du noyau magnétique, ayant une face de fixation opposée à la face active, et ayant une première extrémité (31) articulée selon une charnière fixe pour permettre la rotation de l'armature mobile (3) entre un état de travail et un état de repos vers lequel elle est rappelée par des moyens de rappel élastiques (9). L'armature mobile (3) est attirée par le noyau magnétique (2) lorsque celui-ci conduit le champ magnétique généré par la bobine de commande (5) alimentée. Le noyau magnétique (2) est fixé selon sa surface latérale à une surface de fixation (1d) de l'armature mobile (1) par une soudure laser (23).

    摘要: The purpose of the present invention is to provide an electromagnetic relay in which a movable iron piece is stabilized at an early stage and that has stable operating characteristics. Provided is an electromagnetic relay that comprises the following: a gate-shaped iron core 30; a movable iron piece 40; and a card 50, the movable iron piece 40 that pivots based on the excitation and degaussing of the electromagnet 20 presses the card 50, thereby driving a contact mechanism 60. At least one facing plane out of the facing planes of the one leg 32 of the gate-shaped iron core 30 and the pivoting shaft 43 of the movable iron piece 40 includes a shallow groove 33 for reducing magnetic flux density.
