Abstract: The present invention relates to a relay for an electric vehicle and a method of manufacturing the same, and more particularly, a relay for an electric vehicle where a permanent magnet is integrally formed with a housing formed of a ceramic chamber, and a method of manufacturing the same. The relay, capable of rapidly executing current interruption includes: a fixed contact; a movable contact formed to contact or to be separated from the fixed contact; a shaft connected to the movable contact, and configured to move the movable contact; a housing configured to accommodate therein the fixed contact and the movable contact; an actuator configured to drive the shaft; and a permanent magnet integrally formed with the housing, and configured to extend an arc generated between the fixed contact and the movable contact. The permanent magnet includes an alnico-based material or a neodymium-based material.

Abstract: A high voltage relay device according to the present invention includes fixed contacts, a movable contact provided at one side of the fixed contacts and contactable with or separated from the fixed contacts, fixed-side arc electrodes coupled to the fixed contacts, and a movable-side arc electrode coupled to one side of the movable contact and contactable with or separated from the fixed-side arc electrodes when the movable contact is brought into contact with or separated from the fixed contacts, whereby a generation of arc from primary electrodes when current flows and is cut off can be prevented so as to enhance reliability of the primary electrodes, and also usage of specialized materials may result in reduction of material costs.
