Direct current contactor with moving and fixed contact components located within an arc-extinguishing cavity

A vehicle, comprising a direct current contactor, wherein the direct current contactor comprises:

• a case having an arc-extinguishing cavity and a first baffle is disposed in the arc- extinguishing cavity that divides the arc-extinguishing cavity into a first arc-extinguishing chamber and a second arc-extinguishing chamber;
• two groups of contact components disposed in the case, wherein each group of contact components comprises two moving contacts connected to each other and two fixed contacts opposite to the moving contacts, the fixed contacts extend outside the case;
• and the two groups of contact components are respectively disposed in the first arc-extinguishing chamber and the second arc-extinguishing chamber;
• a drive system, wherein the drive system is connected to the moving contacts of the two groups of contact components and configured to drive the moving contacts to move in a direction close to or away from the fixed contacts, so that the moving contacts are disconnected from or connected to the fixed contacts,
• a first magnet and a second magnet are respectively disposed on two sides that are outside the first arc-extinguishing chamber and that are adjacent to the two moving contacts, the first magnet and the second magnet attract each other to form a first magnetic field, and the first magnet and the second magnet are opposite to gaps between the moving contacts and the fixed contacts;
• a third magnet and a fourth magnet are respectively disposed on two sides that are outside the second arc-extinguishing chamber and that are adjacent to the two moving contacts, the third magnet and the fourth magnet attract each other to form a second magnetic field, and the third magnet and the fourth magnet are opposite to gaps between the moving contacts and the fixed contacts;
• and
• magnetic field directions of the first magnetic field and the second magnetic field are perpendicular to directions of currents flowing through the fixed contacts and the moving contacts, and the magnetic field direction of the first magnetic field is opposite to the magnetic field direction of the second magnetic field;
• and
• a mounting bracket, wherein the mounting bracket comprises a first bracket and a second bracket that are opposite to each other, the first bracket and the second bracket are disposed around a periphery of the case, the first magnet and the second magnet are disposed on an inner side wall of the first bracket, and the third magnet and the fourth magnet are disposed on an inner side wall of the second bracket, wherein the first bracket and the second bracket are U-shaped brackets, a side wall of the U-shaped bracket has a first clamping member, an end of an opening of the U-shaped bracket has a second clamping member protruding towards the inside of the opening, and at least one of the first magnet, the second magnet, the third magnet, or the fourth magnet is disposed on the U-shaped bracket by using the first clamping member and the second clamping member.
