Application: Electromagnetic contactor capable of effectively extinguishing arc (Patent ID: US20240087830A1)
The electromagnetic contactor disclosed in the patent by LS Electric Co Ltd includes an arc extinguishing unit that surrounds the area where the fixed and movable contactors meet, allowing any generated arc to extend towards a grid instead of flowing randomly within the contactor. This design ensures that the arc is quickly and effectively extinguished and discharged outside the contactor through an arc outlet, preventing damage to the contactor components.
The patent claims detail the structure of the magnetic contactor, including components such as the coil, fixed core, movable core, crossbar with movable contact, fixed contact, and wall portions surrounding the fixed contact. The design also incorporates an arc box unit with an arc outlet for efficient arc extinguishing and discharge. The arrangement of wall portions, arc through holes, and grid within the contactor ensures that the arc is directed towards the outlet for safe and effective operation. Additional features like the mesh portion covering the arc outlet further enhance the safety and functionality of the electromagnetic contactor.
