DIRECT CURRENT RELAY

摘要

Disclosed embodiments relate to a direct current relay. In some embodiments, a direct current relay is capable of reducing noise by attenuating an impact generated between a fixed core and a moving core during an ‘ON’ operation, and by attenuating an impact generated between a shaft and a middle plate during an ‘OFF’ operation.

主权项

1. A direct current relay, comprising:
a pair of fixed contacts fixed on one side of a frame; a movable contact disposed below the pair of fixed contacts configured to move linearly, and configured to contact the pair of fixed contacts or to be separated from the pair of fixed contacts; a middle plate disposed below the movable contact; a contact spring disposed between the movable contact and the middle plate; a fixed core disposed at the middle plate, and including a center with a shaft hole; a movable core disposed below the fixed core and configured to move linearly; a shaft including an upper end forming a mounting portion protruding to an upper side of the movable contact, and including a lower end coupled to the movable core; and a tension spring disposed between the movable contact and the mounting portion.
