Abstract: A contact device of present invention includes a first contact portion, a first fixed terminal electrically connected to the first contact portion, a second contact portion, and a second fixed terminal electrically connected to the second contact portion. The contact device further includes a housing being box-like in shape and disposed so as to surround the first and second contact portions, the housing including a bottom plate having a first opening hole through which the first fixed terminal passes and a second opening hole through which the second fixed terminal passes. The contact device further includes a first insulating member being electrically insulating, annular, and directly or indirectly joined to the bottom plate around the first opening hole, and a second insulating member being electrically insulating, annular, and directly or indirectly joined to the bottom plate around the second opening hole.

Abstract: A contact device includes a fixed terminal, a moving contactor, a moving yoke, and a bus bar. The moving contactor moves from a closed position where a moving contact is in contact with a fixed contact to an open position where the moving contact is out of contact with the fixed contact, and vice versa. The moving yoke moves, as the moving contactor moves, in a direction of movement of the moving contactor. The bus bar generates, when energized, a magnetic field having a direction aligned with the direction of movement of the moving contactor. The bus bar is arranged, with respect to the moving yoke when the moving contactor is currently located at the closed position, in a direction in which the moving contactor moves from the open position toward the closed position.

Abstract: A contact apparatus is provided and includes fixed terminals having fixed contacts, a movable contact member having the movable contacts provided on one surface thereof so as to come into contact or out of contact with the fixed contacts, a first yoke arranged at one side of said one surface of the movable contact member, and a second yoke arranged at a side of the other surface of the movable contact member, the second yoke having one surface facing the first yoke through the movable contact member. The first yoke is larger in volume than the second yoke.

Abstract: A contact module includes a pair of contact devices, each of which includes a fixed terminal and a moving contactor. The moving contactor moves from a closed position where the moving contact is in contact with the fixed contact to an open position where the moving contact is out of contact with the fixed contact, and vice versa. One moving contactor generates, when energized, a magnetic field that applies force to the other moving contactor in a direction from the open position of the other moving contactor toward the closed position of the other moving contactor. The other moving contactor generates, when energized, a magnetic field that applies force to the one moving contactor in a direction from the open position of the one moving contactor toward the closed position of the one moving contactor.

Abstract: 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.

Abstract: A bus bar of a contact device includes at least one electric path piece selected from a reverse and a forward electric path piece extending along a direction of current flowing through a moving contactor. The moving contactor is positioned between the reverse electric path piece and a fixed contact in moving directions of the moving contactor with the moving contactor positioned in the closed position. The reverse electric path piece allows current to flow therethrough in an opposite direction from current flowing through the moving contactor. The forward electric path piece is positioned on a same side as the fixed contact relative to the moving contactor in the moving directions of the moving contactor with the moving contactor positioned in the closed position. The forward electric path piece allows current to flow therethrough in a same direction as current flowing through the moving contactor.

Abstract: The contact device switches between a closed state where a movable contact is in contact with the fixed contact and an open state where the movable contact is apart from the fixed contact as the movable element moves. The bus bar is electrically connected to the fixed contact. A magnetic field generated by a current flowing through the bus bar when the contact device is in the closed state applies, to the movable element, force oriented such that the movable element is maintained at a location where the contact device is in the closed state. In such a positional relationship, the bus bar and the electromagnetic device are disposed.
