Abstract: This application provides a direct current contactor which includes a housing, and a first fixed contact and a second fixed contact that are fastened into the housing; a first moving contact and a second moving contact that are located in the housing; a drive mechanism, including: an insulation rod connected to the first moving contact and the second moving contact, and a drive component that drives the insulation rod to drive the first moving contact and the second moving contact to synchronously move toward the first fixed contact and the second fixed contact; and a pressing component configured to push the moving contact firmly against the fixed contact. Only two pairs of contacts are used to implement connection/disconnection of two electrode lines, so that a total contactor resistance is reduced by half compared with that in the conventional technology.
