Abstract: A base of a relay has a leg extending in a contact/separation direction between contacts, and the leg is configured to come into contact with a yoke when the base is incorporated into a case. The leg is spaced away from an upper part of an armature by a distance. This distance is determined so that an upper surface of the armature does not come into contact with the leg in a normal operation of the armature, but the upper surface of the armature comes into contact with a lower surface of the leg when the armature jumps up beyond a movable range thereof due to, for example, a strong impact applied to a vehicle on which the relay is mounted.

Abstract: An electromagnetic relay includes a movable terminal including a movable contact, a fixed terminal including a fixed contact that faces the movable contact, first irons disposed on one of the fixed terminal and the movable terminal, and a second iron disposed on another one of the fixed terminal and the movable terminal such that the second iron at least partially overlaps both of the first irons.

Abstract: Provided is a relay having a relatively small dimension in an alignment direction of contacts, having an easily assembled structure, and capable of extinguishing arcs generated at each contact. The relay comprises: a first terminal having a pair of first contacts; a second terminal having a pair of second contacts which are opposed to the pair of first contacts so as to contact and separate from the respective first contacts; and a first magnet positioned on a side opposed to the pair of first contacts of the first terminal and between the pair of first contacts so that the first magnet does not contact the first terminal, wherein the first magnet is magnetized in a direction along which the pair of first contacts and the pair of second contacts are opposed.

Abstract: An electromagnetic relay including: an electromagnet; a movable spring having a movable contact; a first terminal to which one end of the movable spring is connected; a second terminal having a fixed contact opposite to the movable contact; an actuator that rotates by excitation of the electromagnet, rotates the movable spring, and causes the movable contact to come in contact with the fixed contact or to separate from the fixed contact; a nonmagnetic card to be attached to the actuator; a plurality of magnetic members that sandwich the movable contact and the fixed contact, and apply a magnetic flux to the movable contact and the fixed contact to extend an arc; and a permanent magnet attached between the magnetic members.

Abstract: An electromagnetic relay including: a fixed terminal that includes a fixed contact; a movable spring that includes a movable piece on which a first through-hole is formed; a conductive plate that includes a second through-hole; a movable contact that includes a head part that is in contact with and is separated from the fixed contact, and a leg part that is inserted into the first through-hole and the second through-hole; wherein the conductive plate is disposed between the head part and the movable spring, in a radial direction of the first through-hole and the second through-hole, the head part does not protrude from an outer edge of the conductive plate but protrudes from the outer edge of the movable piece.

Abstract: An electromagnetic relay includes a fixed contact, a movable contact corresponding to the fixed contact, a movable element that retains the movable contact and moves in a contacting direction and a separating direction relative to the fixed contact, an axial core coupled to the movable element, a movable core coupled to the axial core to move in the contacting direction and the separating direction relative to a movement of the axial core, a driving part that drives the movable core in the contacting direction, an urging part that exerts force to the axial core in the separating direction, and a constraining part that constrains the relative movement of the axial core in the separating direction.

Abstract: An electromagnetic relay includes a contact that includes a fixed contact and a movable contact, a permanent magnet provided on the peripheral side of the contact, and a non-magnetic body. The movable contact is displaceable in a first direction to move toward the fixed contact and in a second direction to move away from the fixed contact. The permanent magnet has a polarity direction perpendicular to the first and second directions. The non-magnetic body faces toward the direction of a Lorentz force that acts based on the permanent magnet in a direct electric current flowing through the contact.
