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： A housing includes a first space, a second space, a first hole, a second hole, and an arc extinguishing member. A fixed contact and a movable contact are arranged in the first space. The second space is partitioned from the first space. The first hole communicates the first space and the second space. The second hole communicates the second space with a space outside the second space. The arc extinguishing member releases an arc extinguishing gas into the first space. The second hole has a smaller opening area than the first hole.

摘要： A contact device includes a fixed contact, a movable contact, a housing, and an arc extinguishing member. The movable contact moves between a closed position where the movable contact contacts the fixed contact and an open position where the movable contact is separate from fixed contact. The housing houses the fixed contact and the movable contact. The arc extinguishing member is movably disposed in the housing and discharges an arc extinguishing gas. The arc extinguishing member is disposed facing a gap between the fixed contact and the movable contact when the movable contact is in the open position.

摘要： Provided is an electromagnetic relay that is reduced in size and has great flexibility in designing. For this purpose, when a predetermined time has passed after generation of an arc at least either between a movable contact and a fixed contact or between a movable contact and a fixed contact, an arc generated between the movable contact and the fixed contact is extended by a magnetic field generation unit to be longer than an arc generated between the movable contact and the fixed contact.

摘要： An electromagnetic relay includes a case including a base, a first fixed terminal held by the base, a movable contact piece, a gas inflow space, and a gas passage. The first fixed terminal includes a first fixed contact disposed apart from the base in a first direction inside the case, a contact support portion disposed between the first fixed contact and the base and configured to support the first fixed contact, and a first extending portion extending at an angle from the contact support portion and penetrating the base in the first direction. The movable contact piece includes a first movable contact facing the first fixed contact in the first direction. The gas inflow space is formed between the base and the contact support portion inside the case. The gas passage penetrates the base in the first direction and communicates the gas inflow space with an outside of the case.
