  • Publication number: 20210375569
    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.

  • Publication number: 20210151271
    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.

  • Publication number: 20200381203
    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.

  • Publication number: 20200286702
    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.
