Vacuum circuit interrupter with contact structure including support pins

An interrupter for a circuit breaker, comprising:

• a first conductive rim for providing a conductive path where the current flows;
• a wheel-shaped fixed electrode including a plurality of first conductive spokes connected to the first conductive rim in order to provide the conductive path where the current flows, a plurality of horizontal loops of conductive path being formed by the first conductive rim and the first conductive spokes, a plurality of vertical magnetic fields being formed by the plurality of loops of conductive path;
• a disc-shaped fixed contactor;
• a plurality of first conductive pins for electrically connecting the fixed contactor and the fixed electrode;
• a second conductive rim for providing a conductive path where the current flows;
• a wheel-shaped movable electrode including a plurality of second conductive spokes connected to the second conductive rim in order to provide the conductive path where the current flows, a plurality of horizontal loops of conductive path being formed by the second conductive rim and the second conductive spokes, a plurality of vertical magnetic fields being formed by the plurality of loops of conductive path;
• a plurality of second conductive pins for electrically connecting the movable contactor to the movable electrode;
• and
• a reinforcing member arranged between the fixed electrode and the fixed contactor or between the movable electrode and the movable contactor, in order to prevent an impact generated when the fixed contactor and the movable contactor are contacted from being concentrated on the first conductive pins or the second conductive pins.
