摘要： A multi-phase electromagnetic relay includes a base, lead-out structures and movable-static contact matching structures. Each of lead-out structures includes an input terminal and an output terminal. One movable-static contact matching structure is provided between the input and the output terminals in each of the plurality of lead-out structures. The input and output terminals are respectively led out from the first and second side walls of the base. The input and output terminals bent to the outside of the third side wall of the base, and in a non-crossed and spaced manner. The external connection ends of the input and output terminals are outside the third side wall and are arranged a row parallel to the third side wall. The input and output terminals are respectively arranged at corresponding positions on two sides of the same row. The third side wall is connected between the first and second side walls.

摘要： An arc path formation unit and a direct current relay are disclosed. The arc path formation unit, according to various embodiments of the present disclosure, includes a Halbach array provided in at least one of the forward and backward directions. The Halbach array forms a magnetic field within an arc chamber by itself or along with another magnetic body. An electromagnetic force may be generated for inducing an arc that is generated by a formed magnetic field and current flowing through the direct current relay. The electromagnetic force is generated in a direction away from each fixed contact. Accordingly, the generated arc can be extinguished and discharged effectively.

摘要： An electromagnetic relay includes a case, a movable contact piece, a fixed terminal, a driving device, and an insulating wall. The movable contact piece includes a movable contact. The fixed terminal includes a fixed contact, a contact support portion, an extension portion, and a bent portion. The contact support portion supports the fixed contact. The extension portion extends from the contact support portion in a longitudinal direction of the movable contact piece. The bent portion extends in a bent shape from the extension portion in a first direction from the fixed contact toward the movable contact, and overlaps the movable contact piece in the longitudinal direction of the movable contact piece. The driving device is configured to move the movable contact piece. The insulating wall is integral with the case and is disposed between the bent portion and the movable contact piece.

摘要： The main body frame includes a first frame including a flexible protruding plate portion, a second frame facing the first frame in a first direction to form the housing section, and a snap-fit mechanism connecting the first frame to the second frame. The snap-fit mechanism includes a fitted portion provided on the flexible protruding plate portion and a fitting projection portion provided on a side wall of the second frame and fitting with the fitted portion. The fitting projection portion and the fitted portion are fitted by bringing the first and second frames into relative proximity in the first direction, and the fitting is released by relatively displacing the first and second frames in a second direction orthogonal to the first direction.

摘要： An electromagnetic relay includes a first movable contact piece, a moving member, a coil, and a movable iron core. The movable iron core is connected to the moving member and is configured to move by a magnetic force generated by the coil. The moving member is made of an electrical insulator. The moving member includes a support portion and a connecting portion. The support portion holds a first movable contact piece. The connecting portion is connected to the movable iron core. The connecting portion includes a locking groove and a locking projection. An end of the movable iron core is disposed in the locking groove. The locking projection presses the end of the movable iron core in the locking groove. The locking projection extends in a support direction perpendicular to a moving direction of the moving member.
