摘要： An electromagnetic contact device has a terminal base (18) formed on one end of a coil frame around which a winding of an electromagnetic coil is wound; a terminal (20a) which can be connected to external wiring, and a winding wire binding portion (20e) which can bind an end portion of the winding, wound around the coil frame to establish connection. The coil terminal (20) is a component formed by integrating the terminal (20a), the winding wire binding portion (20e), and a portion to be engaged (20b). This coil terminal (20) is mounted by press-fitting a press-fit engaging portion (18b), which is formed in the terminal base (18), in the portion to be engaged (20b) to establish engagement.

摘要： The present invention provides a contact mechanism that is capable of, without enlarging the entire configuration thereof, preventing the generation of an electromagnetic repulsion that opens a movable contact upon application of a current, and also provides an electromagnetic contactor that uses this contact mechanism. A contact mechanism (CM) has a fixed contact (2) and a movable contact (3) that are inserted in a current-carrying path. In the contact mechanism (CM), at least either the fixed contact (2) or the movable contact (3) is formed into an L-shape or a U-shape so as to generate a Lorentz force that acts against an electromagnetic repulsion in an opening direction, which is generated between the fixed contact (2) and the movable contact (3) upon application of a current.
