摘要： The contact device includes a movable contact that comes into contact with a first fixed terminal by moving a moving body to one side in one direction, and comes away from the first fixed terminal by moving the moving body to the other side in the one direction. The movable contact includes a first contact unit that comes into contact with the first fixed terminal. The first fixed terminal also includes a first surface with which the first contact unit comes into contact from a direction intersecting with one direction. The first contact unit includes a first contact piece on the first contact unit side that comes into contact with the first surface in a stretched manner in a state of being pressed to one side in one direction by the moving body.

摘要： A movable contact of a contact device includes a first contact unit and a second contact unit that come into contact with outer surfaces of fixed terminals and a connecting portion connecting the first contact unit and the second contact unit. Here, the first contact unit separates from the outer surface by moving in a direction that is different from a moving direction of a moving body and that intersects an extending direction of a portion that makes contact with the first contact unit of the outer surface. Also, the second contact unit separates from the outer surface by moving in a direction that is different from the moving direction of the moving body and that intersects an extending direction of a portion that makes contact with the second contact unit of the outer surface.

摘要： Provided is a contact device including a first contact, a second contact that is movable relative to the first contact and is brought into contact with or separated from the first contact, a first body part including the first contact, a second body part including the second contact, and a yoke arranged adjacent to at least one of the first body part or the second body part. At least a part of the yoke is arranged along magnetic flux generated by a current flowing through one body part of the first body part and the second body part that is adjacent to the yoke, in a region where the first body part and the second body part overlap each other when viewed along an axis in which the first contact and the second contact move relative to each other while the first contact and the second contact are in contact with each other.

摘要： A contact device includes: a contact block which includes a fixed contact, and a movable contactor including a movable contact formed to come into and out of contact with the fixed contact; a driving block including a driving shaft which moves the movable contactor, the driving block configured to drive the driving shaft so that the movable contact can come into and out of contact with the fixed contact; and a yoke disposed on one side of the movable contactor in a driving direction and fixed to the movable contactor. One of the yoke and the movable contactor includes a projection projected to the driving direction, and the other of the yoke and the movable contactor includes an insertion hole in which to insert the projection.

摘要： A contact device includes: a contact block which includes a fixed terminal including a fixed contact formed thereon, and a movable contactor including a movable contact formed thereon; and a driving block including a driving shaft to which the movable contactor is attached, the driving block configured to drive the movable contactor. The contact block includes: a biasing portion configured to bias the movable contactor toward one side in a driving shaft direction; and a yoke disposed at least on an opposite side of the movable contactor in the driving shaft direction while the movable contact is in contact with the fixed contact. The biasing portion includes a biasing end configured to make biasing force act on the movable contactor by pressing a member other than the yoke.

摘要： A first conductive member is fixed to a first fixed terminal having a longitudinal direction, and a second conductive member is fixed to a second fixed terminal having a longitudinal direction. The first fixed terminal and the second fixed terminal are fixed to a partition member. A first extension portion of the first conductive member includes a first opposed portion opposed to at least one of the first fixed terminal at a first fixed contact side of the partition member. The first opposed portion extends in the longitudinal direction of the first fixed terminal.

摘要： An electromagnetic relay includes an electromagnet device, an armature and a fixed terminal. By coil current through a coil, the electromagnet device generates first magnetic flux that forces the armature and the electromagnet device together or apart in a first end in a first direction of the armature. The armature is connected with a movable contact at a second end of the first direction and forces the movable contact and a fixed contact together or apart according to coil current. The fixed terminal is electrically connected with the fixed contact, and provided around the armature so as to cross the armature as seen from a second direction perpendicular to the first direction with the armature closing the fixed and movable contacts. Electric current through the fixed terminal generates a second magnetic flux in the armature, a direction of which is opposite to that of the first magnetic flux.
