  • Publication number: 20240006138
    Abstract: Disclosed are a movable contact part and a direct current relay including same. The movable contact part comprises an upper yoke. The upper yoke generates a magnetic force that attenuates the electromagnetic repulsive force generated between a movable contact and a fixed contact. The upper yoke includes a cover part covering the movable contact from above and an arm part connected to the cover part and covering the movable contact from both sides. The arm part is thinner than the cover part. A curved portion of the arm part is shorter than the cover part and an extension portion. Thus, even though the total weight of the upper yoke is reduced, the area of the upper yoke is increased, and the thickness and length of a support part can be maintained. Consequently, the intensity of the magnetic force of the upper yoke can be enhanced.

  • Publication number: 20230411097
    Abstract: Disclosed are a movable contact part and a direct current relay comprising same. The movable contact part, according to one embodiment of the present disclosure, comprises a lower yoke. The lower yoke forms a magnetic force for canceling an electromagnetic repulsive force generated between a movable contact and a fixed contact. The lower yoke comprises: a support part for supporting the movable contact; and a wing part connected to the support part. The wing part is formed so as to be thinner than the support part. According to one embodiment, the wing part is formed so as to be shorter than the support part. Thus, the total weight of the lower yoke is decreased, while the area of the lower yoke is increased, and the thickness and length of the support part may be maintained. Consequently, the lower yoke magnetic strength, operational reliability, and vibration or impact resistance may be improved.
