Abstract: An electromagnetic relay of the present disclosure includes a fixed terminal having a fixed contact, a movable contactor having a movable contact, a movable portion that moves the movable contactor between a first position and a second position, an electromagnet device that drives the movable portion, a contact container that contains the fixed contact and the movable contact, a housing that contains the contact container and has a first opening, a sealing material disposed in a path communicating with an outside of the electromagnetic relay, the path being between the housing and the contact container, and a heat conductive member disposed in a first region surrounded by the contact container, the housing, and the sealing material.

Abstract: A displaceable portion of a moving contactor is connected to, and electrically conductive with, a pair of moving contacts. An armature actuates the moving contactor. The armature has an adhering portion to be adhered onto an electromagnet. A space inside an opening that exposes a part (an exposed part) of the displaceable portion crosses a predetermined plane. The predetermined plane intersects at right angles with an arrangement direction (a first direction) in which the pair of moving contacts is arranged side by side. The predetermined plane passes through a center between both ends in the arrangement direction of the adhering portion.

Abstract: An electromagnetic relay unit according to the present disclosure includes a first contact device, a second contact device, a first electromagnet device, a second electromagnet device, and a housing accommodating a first contact accommodation part and a second contact accommodation part. A first thermal conduction member is provided between the housing and the first contact accommodation part. A second thermal conduction member is provided between the housing and the second contact accommodation part.

Abstract: An electromagnetic relay includes an exciting coil, a pair of fixed contacts, a movable spring, a magnet, and a yoke in contact with the magnet. The pair of fixed contacts is arranged along a first direction. The movable spring comes into contact with or moves away from the fixed contacts in response to the turn on or off of current to the exciting coil. The magnet prolongs the arc generated between the fixed contacts and the movable spring. The magnet is adjacent to the fixed contacts along a second direction orthogonal to the first direction, and is adjacent to the exciting coil along a third direction orthogonal to the first direction and the second direction. The yoke is adjacent to the fixed contacts along the third direction in a state where the yoke is in contact with the magnet.

Abstract: An electromagnetic relay includes an electromagnet block, a pair of fixed contacts, a movable spring, and a stopper. The electromagnet block includes an exciter coil and an armature. The movable spring includes a fixed portion and a movable portion. The fixed portion is fixed to the electromagnet block. The movable portion contacts fixed contact and is separated from the fixed contacts in response to turning on and off of an energizing of the exciter coil. The stopper configured to restrict a movement of the movable portion. The armature is fixed to the movable portion and is displaced unitarily with the movable portion. The movable spring is configured to, upon turning on the energizing of the exciter coil, cause the movable portion to move, by magnetic force, in an approaching direction in which the movable portion approaches the fixed contacts with the fixed portion functioning as a fulcrum, and contact the fixed connection portions.
