Abstract: A direct-current contactor includes a contact assembly, an arc extinguishing assembly, and a drive assembly. The arc extinguishing assembly is disposed around the contact assembly. The contact assembly includes a moving contact mechanism and a stationary contact mechanism that are disposed in pairs. The moving contact mechanism includes a moving contact. The stationary contact mechanism includes a stationary contact and an arc introducing plate disposed around the stationary contact. The arc introducing plate is configured to introduce an electric arc generated between the moving contact mechanism and the stationary contact mechanism into the arc extinguishing assembly. The drive assembly is configured to drive a connection or a disconnection of the moving contact and the stationary contact.
