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： 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, a movable contact piece, and a magnet portion. The pair of fixed terminals includes fixed contact. The movable contact piece that includes a movable contact disposed facing the fixed contact and that is movable in a first direction in which the movable contact contacts the fixed contact and in a second direction in which the movable contact separates from fixed contact. The magnet portion generating a magnetic field for extending an arc generated between the fixed contact and the movable contact. At least one of a corner portion in the first direction side of the fixed terminal located in an arc extension direction in which the arc is extended or a corner portion in the second direction side of the movable contact piece located in the arc extension direction has a chamfered shape in a range where the arc passes through.

摘要： An electromagnetic relay includes a base, an electromagnet block mounted on an upper surface of the base, a movable iron piece configured to be rotatable based on excitation and non-excitation of the electromagnet block, a movable contact piece configured to be rotatable integrally with the movable iron piece, a movable contact fixed to a free end portion of the movable contact piece, and a fixed contact fixed to a fixed contact terminal, and disposed so as to be separable from and contacted with the movable contact along with rotation of the movable contact piece. A permanent magnet configured to induce an arc generated between the movable contact and the fixed contact in a predetermined direction is housed in a recessed portion formed on a lower surface of the base in a direction toward a side opposite to the movable contact as viewed from the fixed contact terminal.

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： A relay includes a movable contact piece having a first movable contact and a second movable contact, a first fixed terminal having a first fixed contact, a second fixed terminal having a second fixed contact, a drive device configured to move the movable contact piece, and the wall portion disposed inside the first fixed contact and the second fixed contact in a longitudinal direction. At least a part of the wall portion is disposed at a position beyond the first fixed contact and the second fixed contact toward the movable contact piece in a moving direction of the movable contact piece. The movable contact piece has a shape so as to avoid the wall portion in a contact state where the first movable contact is in contact with the first fixed contact and the second movable contact is in contact with the second fixed contact.
