Abstract

An arc path forming unit and a direct current relay including same are illustrated. The arc path forming unit according to an embodiment of the present invention comprises multiple magnets. Each of the magnets is configured to form a magnetic field at a point where each stationary contact is located. Each of the magnets located adjacent to each stationary contact is configured such that the opposite surfaces thereof have different polarities. A current flowing through a stationary contact and a movable contact and a magnetic field formed by each of the magnets generate an electromagnetic force. The electromagnetic force travels in a direction away from the center of the direct current relay. Therefore, a generated arc travels in the direction of the electromagnetic force and is thus moved in a direction away from the center of the direct current relay. Accordingly, the direct current relay can be prevented from being damaged.
