Contactor

A contactor, comprising:

• an upper insulation housing having an arc extinguishing chamber;
• a movable terminal movably disposed in the arc extinguishing chamber;
• a pair of static terminals located above the movable terminal and fixed to the upper insulation housing;
• an insulation bracket installed in the arc extinguishing chamber;
• an upper magnetic conductor fixed between the upper insulation housing and the insulation bracket, the upper magnetic conductor is stationary relative to the upper insulation housing;
• and
• a lower magnetic conductor assembled onto the movable terminal to move synchronously with the movable terminal, the movable terminal is movable along a vertical direction between an open position electrically separated from the pair of static terminals and a closed position electrically in contact with the pair of static terminals, and when the movable terminal is moved to the closed position, there is a predetermined gap between the upper magnetic conductor and the lower magnetic conductor to prevent the upper magnetic conductor from colliding with the lower magnetic conductor.
