摘要： A relay includes a fixed contact, a movable contact piece including a movable contact, a movable portion, a coil, a return spring, and a contact spring. The movable portion includes a drive shaft and a movable iron core. The drive shaft is fixed to the movable contact piece in a contact case and extends from an inside of the contact case to an outside of the contact case. The movable iron core is connected to the drive shaft outside the contact case. The return spring urges the movable portion in an open direction in which the movable contact is separated from the fixed contact. The contact spring urges the drive shaft in a contact direction in which the movable contact contacts the fixed contact. The contact spring is arranged outside the contact case.

摘要： The invention provides a sealed contact device capable of extinguishing an arc which extends in an arbitrary direction. The sealed contact device includes a housing; a fixed contact and a movable contact disposed in the housing in such a manner as to face each other; and permanent magnets which are disposed with the fixed contact and the movable contact interposed therebetween and which attracts an arc between the fixed contact and the movable contact using a magnetic force. An arc shielding member is disposed at a position to which the arc is attracted by current flowing between the fixed contact and the movable contact and by the magnetic force between the permanent magnets, in the housing.

摘要： A relay includes a movable contact piece having a movable contact, a fixed contact, a drive device configured to move the movable contact piece, a magnet to apply a Lorentz force to an arc in a first extension direction, a fixed terminal having an intermediate portion to apply a Lorentz force to the arc in a second extension direction, and a wall portion. The wall portion includes first and second wall surfaces. The first wall surface is disposed to face an arc-extinguishing space, and is disposed opposite to the movable contact and the fixed contact in the first extension direction. The second wall surface is disposed to face the arc-extinguishing space and is disposed downstream in the second extension direction with respect to the first wall surface. A distance from the movable contact piece to the second wall surface differs from a distance to the first wall surface.

摘要： An electromagnetic relay includes a base, an electromagnet block having a spool with a through hole opening at a flange portion thereof and mounted on an upper surface of the base, a movable iron piece, a movable contact piece rotatable integrally with the movable iron piece, a movable contact fixed to a free end of the movable contact piece, and a fixed contact fixed to a fixed contact terminal and contactable with and separable from the movable contact along with rotation of the movable contact piece. Insulating ribs project from an inward facing surface of a spacer integrally formed with the movable iron piece and an outward facing surface of the flange portion respectively such that the insulating ribs intercept a straight line connecting a magnetic pole portion projecting through the through hole and the fixed contact or the fixed contact terminal with a shortest distance.

摘要： An electromagnetic relay includes a pair of fixed terminals including a fixed contact, a movable contact piece, a housing portion, and a magnet portion. The movable contact piece includes a movable contact disposed facing the fixed contact. The movable contact piece is movable in a first direction in which the movable contact contacts the fixed contact and a second direction in which the movable contact separates from the fixed contact. The housing portion includes a housing space housing the fixed contact and movable contact piece. The magnet portion includes a pair of magnets disposed around the housing portion so as to face each other in a longitudinal direction of the movable contact piece and extending in the second direction beyond the housing space. The magnet portion generates a magnetic flux flowing in a direction parallel to the longitudinal direction between the fixed contact and the movable contact.
