High-voltage direct-current contactor

The utility model proposes a high-voltage direct-current contactor, and the contactor comprises a housing, an arc extinguish chamber, a first static contact, a second static contact, a movable contact, an insulating top block, and a magnetic driving mechanism. The arc extinguish chamber and the magnetic driving mechanism are disposed in the housing, and the first and second contacts are arranged oppositely at an interval. Moreover, the wiring end of the first static contact and the wiring end of the second static contact are exposed at the top of the housing. The contact end of the first static contact and the contact end of the second static contact are both disposed in the arc extinguish chamber. The insulating top block is disposed in the arc extinguish chamber, and is arranged at intervals opposite to the contact end of the first static contact and the contact end of the second static contact. The first surface of the insulating top block is fixedly connected with the movable contact which is arranged to be opposite to the contact end of the first static contact. The movable contact is electrically connected with the contact end of the second static contact through a flexible metal piece. One end of a magnetic movable iron core of the magnetic driving mechanism passes through the arc extinguish chamber, and then is fixed on the second surface of the insulating top block.
