Abstract
The present invention discloses an electromagnetic coil device including a coil body having a connection terminal portion projecting from a circumferential surface of the coil body, a buckle having a positioning flat plate portion and an inserting flat plate portion fixedly connected to the positioning flat plate portion. The inserting flat plate portion is pottedly connected to the connection terminal portion with potting material. The electromagnetic coil device can, on the one hand, reduce the manufacturing cost and improve the reliability of the connection between the coil body and the buckle, and on the other hand, prevent the coil body from being damaged by welding and thus improve the life thereof.
