Magnetic contactor |
摘要 |
Disclosed is a magnetic contactor. The magnetic contactor includes a frame, a bobbin provided in the frame, and configured to include a hollow part, a movable core movably inserted into the hollow part in an axial direction, a yoke disposed at the outer surface of the bobbin to be separated from the coil and to face each other, and configured to act as a fixed core, and a manipulating circuit part disposed at the outer surface of the bobbin in parallel with a moving direction of the movable core to intersect the yoke. The coil is wound around an outer surface of the bobbin. Accordingly, a coil having a broad rated voltage range is used. Also, a structure of a product is simplified, and a space is broadly used. |

1. A magnetic contactor comprising:
a frame; a bobbin provided in the frame, and configured to include a hollow part, wherein a coil is wound around an outer surface of the bobbin; a movable core movably inserted into the hollow part in an axial direction; a yoke disposed at the outer surface of the bobbin to be separated from the coil and to face each other, and configured to act as a fixed core; and a manipulating circuit part disposed at the outer surface of the bobbin in parallel with a moving direction of the movable core to intersect the yoke, wherein the manipulating circuit part comprises: a printed circuit board (PCB); an inverting switch provided on the PCB, wherein the inverting switch is switched on or off on the contrary to a contact of a main circuit; and a voltage dropping element provided on the PCB, wherein when the inverting switch is inverted, the voltage dropping element drops an external voltage applied thereto to reduce a voltage applied to a coil. |
