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.

Contact device, electromagnetic relay and electrical device

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.

Contact device, electromagnetic relay using the same, and method for manufacturing contact device

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.

Contact apparatus

A contact device includes a contact point block, a drive unit, and permanent magnets. The contact point block includes fixed terminals having fixed contact points and a movable contactor having movable contact points arranged side by side on one surface of the movable contactor. The movable contact points are configured to come into contact and out of contact with the fixed contact points. The drive unit drives the movable contactor such that the movable contact points come into contact and out of contact with the fixed contact points. The permanent magnets are arranged in a mutually opposing relationship across the contact point block along a direction orthogonal to an arrangement direction of the movable contact points and to a direction in which the movable contact points come into contact and out of contact with the fixed contact points. The permanent magnets are provided with mutually-opposing surfaces having the same polarity.

Contact device

A contact apparatus includes a case; fixed terminals having the fixed contacts arranged within the case; 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 on said one surface of the movable contact member within the case, one surface of the first yoke facing an inner surface of the case and the other surface thereof facing said one surface of the movable contact member; and a second yoke arranged on the other surface of the movable contact member within the case, the second yoke having one surface facing the other surface of the first yoke through the movable contact member. The first yoke is larger in volume than the second yoke.
