An auxiliary contact system of a contactor includes an auxiliary movable contact, an auxiliary static contact corresponding to the auxiliary movable contact, and a rotation member configured to be rotatable between a first position and a second position. In the first position, a main movable contact of the contactor is driven by the rotation member to an electric contact position in which the main movable contact contacts a main static contact and the auxiliary movable contact is in the electric contact position contacting the auxiliary static contact. In the second position, the main movable contact of the contactor is driven by the rotation member to an electric separation position where the main movable contact is separated from the main static contact and the rotation member pushes the auxiliary movable contact to the electric separation position separated from the auxiliary static contact.

A relay includes a housing, an electric contact system in the housing, an electromagnetic system in the housing, and a magnetic blowing arc-extinguish device. The electric contact system includes a static contact with a static contact portion and a movable contact with a movable contact portion. The electromagnetic system is configured to drive the movable contact to move between a closed position in which the movable contact is in electrical contact with the static contact and an opened position in which the movable contact is separated from the static contact. The magnetic blowing arc-extinguish device includes a permanent magnet statically provided near the static contact and configured to lengthen an electric arc between the static contact portion and the movable contact portion by an electromagnetic force to extinguish the electric arc.

A contactor includes two static contacts and a movable contact. Two ends of the movable contact selectively electrically contact the two static contacts, respectively. The contactor further includes a rotatable member rotatable about a central axis, with the movable contact being mounted thereon. The rotatable member is rotatably mounted on a support plate. Two ceramic members are mounted on the support plate, with each defining an internal region. Two permanent magnets are mounted on the support plate and located outside of the two ceramic members, respectively. The two ends of the movable contact are located in respective internal regions of the two ceramic members, such that an electrical arc generated between the movable contact and the static contact is located within the internal region.

An electrical contactor system includes a stationary contactor having a stationary contact, a moving contactor having a moving contact, a rotating member, a magnetic blow-out arc quenching device including a permanent magnet, and an isolation arc quenching device. The moving contactor is mounted on the rotating member and is rotatable between a connected position and a disconnected position. The moving contact is in electrical contact with the stationary contact when the moving contactor is rotated to the connected position, the moving contact is separated from the stationary contact when the moving contactor is rotated to the disconnected position. The permanent magnet is statically disposed in a vicinity of the stationary contactor for elongating an arc between the stationary contact and the moving contact by an electromagnetic force so as to extinguish the arc. The isolation arc quenching device pushes the arc toward the permanent magnet so as to force the arc to move to a vicinity of the permanent magnet.

Electrical contactor system

An electrical contact system includes a static contact, a movable contact movable between a switch-on position with the movable contact in electrical contact with the static contact and a switch-off position with the movable contact separated from the static contact, and an arc extinguishing device including an arc extinguishing member and a driving mechanism. When the movable contact is moved to the switch-on position, the arc extinguishing member is moved beyond a contact area between the movable contact and the static contact and the movable contact is allowed to be in electrical contact with the static contact. When the movable contact is moved to the switch-off position, the arc extinguishing member is moved between the movable contact and the static contact and the movable contact is electrically isolated from the static contact.

Electrical contact system

An electrical contact system includes a pair of static contacts, a rotatable member disposed between the static contacts and rotatable about a rotation axis between a first position and a second position, and a movable contact mounted on and rotated with the rotatable member. A pair of opposite ends of the movable contact are in electrical contact with the static contacts when the rotatable member is rotated to the first position. The ends of the movable contact are separated from the static contacts when the rotatable member is rotated to the second position. The movable contact has a Z-shape and is slidably mounted on the rotatable member. The movable contact slides under a pushing force from a first static contact of the static contacts toward a second static contact of the static contacts to be in electrical contact with the second static contact.

An electric contact system includes a moving member movable in a vertical direction, a movable contact mounted on and moved with the moving member, a static contact, and an arc extinguishing device including a movable bracket movable in a horizontal direction and an arc extinguishing sheet mounted on and movable with the movable bracket. The movable contact moves between a switch-on position and a switch-off position. When the movable bracket is moved to a first position, the arc extinguishing sheet is moved beyond a contact area between the movable contact and the static contact and allows the movable contact to electrically contact the static contact. When the movable bracket is moved to a second position, the arc extinguishing sheet is moved into the contact area between the movable contact and the static contact to electrically isolate the movable contact from the static contact.

Electric contact system

An electrical contact system includes a static contact having a static contact point, a movable contact having a movable contact point, a rotating member on which the movable contact is mounted, and an arc extinguishing device having an arc extinguishing sheet. The movable contact is rotatable with the rotating member between a switch-on position and a switch-off position. When the movable contact is rotated to the switch-on position, the arc extinguishing sheet is rotated beyond a contact area between the movable contact point and the static contact point, allowing electrical contact of the movable contact point with the static contact point. When the movable contact is rotated to the switch-off position, the arc extinguishing sheet is rotated into the contact area between the movable contact point and the static contact point, electrically isolating the movable contact point from the static contact point and cutting off an electric arc.

A magnetic system of an electromagnetic relay comprises a coil, an iron core, a yoke, and an armature. The iron core extends through the coil and has a first end and a second end opposite to the first end. A second part of the yoke is connected to the first end of the iron core and a first part of the yoke extends in a length direction of the iron core and is separated from the coil. The armature is disposed at the second end of the iron core and has a main body and a bending portion bent from the main body by a predetermined angle. The main body faces an end surface of the second end of the iron core. The bending portion is disposed at an inner side of an end portion of the first part of the yoke and faces the iron core.

Magnetic system of electromagnetic relay

A polar relay is provided including: an insulation housing, an armature assembly, and a coil assembly. The armature assembly is pivotably mounted within the insulation housing. The armature assembly is rotatable between a first position and a second position, with one end of the iron core in contact with one armature of the pair of armatures while the other end of the iron core is spaced apart from and thus out of contact with the pair of armatures by corresponding gaps therebetween. The gaps are provided without providing a magnetic isolation plate between or applying an isolation layer onto contact layers of the armature and the iron core. The armature assembly is rotatable around a vertical pivot axis, avoiding changing a position of the pivot point during the movement of the iron core, stabilizing the action of the armature assembly, and ensuring the continuity of the action of the product.
