Patent number: 11804348Abstract: Disclosed are an arc path formation unit and a direct current relay including same. An arc path formation unit according to an embodiment of the present disclosure comprises a plurality of magnet parts. The magnet parts, positioned adjacent to respective stationary contacts, are configured such that surfaces facing each other have different polarities. Also, some of the plurality of magnet parts are disposed at an incline relative to other magnet parts. Thus, magnetic field is formed by the plurality of magnet parts to obliquely pass by each of the stationary contacts. The electromagnetic force generated by the magnetic field is imparted in a direction away from the central region of a direct current relay. Accordingly, the generated arc moves in a direction away from the central region of the direct current relay, and thus damage to the direct current relay can be prevented.Type: GrantFiled: April 7, 2020Date of Patent: October 31, 2023Assignee: LS ELECTRIC CO., LTD.Inventors: Jinhee Park, Jungwoo Yoo
