摘要： An electromagnetic relay includes a fixed terminal, a movable contact piece, and a support portion supporting the fixed terminal. The fixed terminal includes a fixed contact, a first terminal portion on which the fixed contact is disposed, a second terminal portion extending from one of both ends of the first terminal portion, a first protrusion disposed on the second terminal portion. The fixed terminal is bent between the first and second terminal portions. The first terminal portion has a first terminal surface opposite to the movable contact piece. The second terminal portion has a second terminal surface connected to the first terminal surface. The support portion has a contact surface contacting the first terminal surface of the first terminal portion, and a first side surface including a first groove where the first protrusion is fitted. The first protrusion is disposed on the second terminal surface of the second terminal portion.

摘要： An electromagnetic relay includes a first fixed terminal including a first fixed contact, a second fixed terminal including a second fixed contact, a movable contact piece including first and second contacts, a drive device including a coil, a case, and a magnet. The case includes an accommodation space accommodating the first fixed contact, the second fixed contact, and the movable contact piece, and a first arc extension space at least partially disposed between the coil and the magnet. The magnet is disposed so as to overlap with the coil in a third direction orthogonal to the moving direction and a longitudinal direction of the movable contact piece. The magnet configured to extend a first arc generated between the first fixed contact and the first movable contact and a second arc generated between the second fixed contact and the second movable contact in the longitudinal direction of the movable contact piece.

摘要： An electromagnetic relay includes a case, a first fixed terminal including a first fixed contact, a second fixed terminal including a second fixed contact, a movable contact piece including first and second movable contacts, a first magnet, a gas flow path, and a partition member. The case includes an accommodation space and a side wall covering the accommodation space in a first direction. The accommodation space includes a first space where the first fixed contact is disposed and a second space where the second fixed contact is disposed. The first magnet configured to extend a first arc generated between the first fixed contact and the first movable contact in the first direction. The gas flow path is disposed between the side wall and the movable contact piece. The gas flow path includes an inlet communicating with the first space and an outlet communicating with the second space.

摘要： An electromagnetic relay includes a first fixed terminal, a second fixed terminal, a movable contact piece, a case, a magnet, and a gas flow path. The first fixed terminal includes a first fixed contact. The second fixed terminal includes a second fixed contact. The movable contact piece includes a first movable contact and a second movable contact. The case includes an accommodation space where the first fixed contact, the second fixed contact, and the movable contact piece are accommodated, a gas inflow space separate from the accommodation space, and a side wall covering the accommodation space and the gas inflow space in a first direction. The magnet is disposed between the accommodation space and the gas inflow space. The gas flow path is disposed between the side wall of the case and the magnet and is configured to communicate the accommodation space with the gas inflow space.

摘要： An electromagnetic relay includes a first fixed terminal, a second fixed terminal, a movable contact piece, a movable member, a contact spring, and an electromagnet block. The movable member is configured to move in a moving direction including a first direction and a second direction. The contact spring biases the movable contact piece in the first direction. The electromagnet block includes a movable iron piece and moves the movable member in the moving direction. The movable contact piece and the contact spring are disposed in the movable member by insertion from a side opposite to a side where the electromagnet block is located. The movable member includes a first member constituted by a single member. The first member includes a press portion to be pressed by the movable iron piece in accordance with rotation of the movable iron piece, and a support portion configured to support the movable contact piece.

摘要： An electromagnetic relay includes a first fixed terminal including a first fixed contact, a second fixed terminal including a second fixed contact, a movable contact piece, a case, a drive device, and a first magnet. The movable contact piece includes a first movable contact and a second movable contact. The case includes an accommodation space and a side wall covering the accommodation space in a first direction. The first magnet extends an arc generated between the first fixed contact and the first movable contact in a second direction opposite to the first direction. The first fixed terminal includes a first end. The first end of the first fixed terminal includes a tapered portion inclined in the second direction from the first fixed contact toward the first magnet and that at least partially overlaps with the first magnet when viewed from a moving direction of the movable contact piece.
