Abstract
A first yoke is arranged in a contact direction with respect to a movable contact piece. A second yoke is arranged in an opening direction with respect to the movable contact piece. The first yoke and the second yoke are configured to generate a magnetic force that attracts the first yoke and the second yoke to each other when the movable contact contacts the fixed contact and is energized. The first yoke and the second yoke are arranged not to contact each other so that the movable contact piece can contact the fixed terminal in a state where the movable contact and the fixed contact are lost.
Claims5
A relay comprising:
- a movable contact piece including a movable contact;
- a fixed terminal including a fixed contact arranged to face the movable contact;
- a drive device configured to move the movable contact piece in a moving direction, the moving direction including a contact direction in which the movable contact is close to the fixed contact and an opening direction in which the movable contact separates from the fixed contact;
- a first yoke arranged in the contact direction with respect to the movable contact piece;
- and
- a second yoke arranged in the opening direction with respect to the movable contact piece,
- the first yoke and the second yoke being configured to generate a magnetic force that attracts the first yoke and the second yoke to each other when the movable contact contacts the fixed contact and is energized, and
- the movable contact piece being configured to contact the fixed terminal without the first yoke and the second yoke contacting each other in a state where the movable contact and the fixed contact are lost or have disappeared.
