Abstract

A relay includes first and second fixed contacts, first and second fixed terminals, first and second movable contacts, a movable contact piece, a drive shaft, a stopper, and a housing. The drive shaft supports the movable contact piece to be movable relative to the drive shaft. The stopper is connected to the drive shaft above the movable contact piece. The stopper restricts an upward movement of the movable contact piece with respect to the drive shaft. The drive shaft is configured to move to an open position and a closed position. The closed position is located above the open position. The first fixed terminal includes a first uppermost portion in the housing. The second fixed terminal includes a second uppermost portion in the housing. In a state where the drive shaft is at the closed position, the stopper is located below the first uppermost portion and the second uppermost portion.

Dependent claims

A relay comprising:

a first fixed contact;
a second fixed contact arranged apart from the first fixed contact in a left-right direction;
a first fixed terminal to which the first fixed contact is connected;
a second fixed terminal to which the second fixed contact is connected;
a first movable contact arranged below the first fixed contact;
a second movable contact arranged below the second fixed contact;
a movable contact piece to which the first movable contact and the second movable contact are connected, the movable contact piece being configured to move in a vertical direction;
a drive shaft extending from the movable contact piece in the vertical direction, the drive shaft being configured to support the movable contact piece so as to be movable relative to the drive shaft;
a stopper connected to the drive shaft above the movable contact piece, the stopper being configured to restrict an upward movement of the movable contact piece with respect to the drive shaft;
and
a housing configured to accommodate the first fixed terminal, the second fixed terminal, the movable contact piece, the drive shaft, and the stopper, wherein
the drive shaft is configured to move to an open position and a closed position,
in a state where the drive shaft is at the open position, the first movable contact is separated from the first fixed contact, and the second movable contact is separated from the second fixed contact,
the closed position is located above the open position,
in a state where the drive shaft is at the closed position, the first movable contact contacts the first fixed contact, and the second movable contact contacts the second fixed contact,
the first fixed terminal includes a first uppermost portion in the housing,
the second fixed terminal includes a second uppermost portion in the housing, and
in a state where the drive shaft is at the closed position, the stopper is located below the first uppermost portion of the first fixed terminal and the second uppermost portion of the second fixed terminal in the housing.
