Magnetic contactor

摘要

Disclosed is a magnetic contactor. A free space in which a DC converting circuit is provided is in a product can be secured by changing shapes of the movable core and the fixed core, and thus, in association with a low-capacity product, external AC power may be converted into DC power even without enlarging a size of a product. Also, a normal position member may be included in a movable core, and may induce the movable core to the original position, and thus, a mechanical mechanism relationship between the switch manipulating part included in the movable core and the other element is maintained.

主权项

1. A magnetic contactor comprising:
a frame configured to include a fixed contact which is connected to a power source and a load; a holder movably provided in the frame, and configured to include a movable contact and a fixed contact which are disposed to contact each other and to be separated from each other; a movable core coupled to one end of the holder, and configured to include a switch manipulating part; a bobbin configured to include a coil which is wound around an outer surface, wherein the bobbin generates a magnetic force when external power is applied to the coil; a fixed core coupled to the bobbin; an elastic member disposed between the holder and the bobbin, wherein the elastic member restores the movable core to an original position when the external power is cut off; an inverting switch provided within a moving range of the switch manipulating part, wherein an internal contact of the inverting switch is inverted when the inverting switch is contacted by switching manipulating part; an electronic circuit part configured to include a voltage dropping element, and receive an inversion signal from the inverting switch to control a current applied to the coil; and a normal position member configured to fix the switch manipulating part to a normal switch to induce a contact between the inverting switch and the switch manipulating part.
