An electromagnetic relay includes: a coil; a housing that supports the coil; a non-movable portion supported by the housing and including a fixed core and a fixed magnetic path defining member; and a movable portion provided to be reciprocally movable along a center axis line of the coil according to an energization state of the coil. The movable portion includes a movable core disposed to face the fixed core along the center axis line. The movable portion integrally has a flange portion protruding in a coil radial direction perpendicular to the center axis line to define a separation distance and/or a facing area in a magnetic gap between the fixed magnetic path defining member and the movable core by abutting against the non-movable portion.

The present disclosure relates to a direct current relay and, more particularly, to a direct current relay including a mover assembly having improved support force with respect to a movable contactor. The direct current relay according to an embodiment of the present disclosure comprises a pair of fixed contactors and a movable contactor which is moved up and down by an actuator to come into contact with or be separated from the pair of fixed contactors, comprises a mover support disposed below the movable contactor and connected to the actuator by a shaft; a mover holder disposed above the movable contactor and fixed to the mover support; a contact pressure spring disposed between the movable contactor and the mover support to provide a contact pressure to the movable contactor; and a supporting pin installed to extend through the movable contactor and the mover holder.

An electromagnetic relay includes a first movable contact piece, a first movable contact, a second movable contact, a moving member, a coil, and a movable iron core. The moving member holds the first movable contact piece. The moving member is made of a resin having electrical insulation. The moving member includes a first member and a second member. The first member is connected to a movable iron core. The second member is a separate body from the first member. The second member is connected to the first member by snap fitting. The first member includes a convex portion. The convex portion projects toward the second member in a moving direction of the moving member. The second member includes an inspection hole. The inspection hole faces the convex portion in the moving direction and extends in the moving direction.

An electromagnetic relay includes a base, a first terminal, a fixing member, and a first adhesive. The base includes a first hole. The base is made of a thermosetting resin. The first terminal extends through the first hole. The fixing member is a separate body from the base. The fixing member has higher elasticity than the thermosetting resin. The fixing member fixes the first terminal to the base. The fixing member includes a first support wall and a first recess. The first support wall is disposed between an inner surface of the first hole and the first terminal. The first support wall extends upward along the first terminal. The first recess is disposed on an upper surface of the first support wall and faces the first terminal. The first adhesive is filled in the first recess. The first adhesive adheres the first terminal and the first support wall.

An electromagnetic relay includes a first movable contact piece, a moving member, a coil, and a movable iron core. The moving member holds the first movable contact piece. 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 resin having electrical insulation. The moving member includes a first member and a second member. The second member is connected to the first member by snap fitting. The first member includes a first protrusion. The second member includes a second main body, a first locking portion, and a first arm. The first locking portion locks to the first protrusion. The first arm connects the second main body and the first locking portion. A thickness of the first arm is smaller than a thickness of the first locking portion.

An electromagnetic relay includes a moving member, a yoke, a guide member, and a movable iron core. The yoke includes a plate portion and a yoke hole. The guide member is disposed in the yoke hole. The movable iron core is connected to the moving member.

The movable iron core includes a tubular portion. The tubular portion includes a first end surface and a second end surface. The tubular portion is disposed in the guide member. The plate portion includes a first surface and a second surface. In a case where the moving member is located at the closed position, the first end surface is located within a range from a first position to a second position. The first position is a position corresponding to the first surface. The second position is located at a center of the first surface and the second surface.

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.
