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.
