Abstract: An electromagnetic relay includes a case, a fixed terminal, and a female screw member. The fixed terminal includes an external connecting portion. The external connecting portion has a screw insertion hole, exposed to the outside from the case, and configured to be screwed to an external terminal. The female screw member is prevented from rotating by the case. The case includes a held portion that is held between the external connecting portion of the fixed terminal and the female screw member in a direction of penetration of the screw insertion hole, the direction of penetration including a first direction from the external connecting portion toward the female screw member and a second direction from the female screw member toward the external connecting portion.

Abstract: An electromagnetic relay includes a case, a movable contact piece, a fixed terminal, a driving device, and an insulating wall. The movable contact piece includes a movable contact. The fixed terminal includes a fixed contact, a contact support portion, an extension portion, and a bent portion. The contact support portion supports the fixed contact. The extension portion extends from the contact support portion in a longitudinal direction of the movable contact piece. The bent portion extends in a bent shape from the extension portion in a first direction from the fixed contact toward the movable contact, and overlaps the movable contact piece in the longitudinal direction of the movable contact piece. The driving device is configured to move the movable contact piece. The insulating wall is integral with the case and is disposed between the bent portion and the movable contact piece.

Abstract: An electromagnetic relay includes a fixed contact, a movable contact, a movable contact piece, a movable iron core, a drive shaft, a coil, and a stopper. The movable iron core is movable in a moving direction including a contact direction in which the movable contact approaches the fixed contact and a separation direction in which the movable contact separates from the fixed contact. The movable iron core includes a shaft hole extending in the moving direction. The drive shaft is connected to the movable contact piece. The drive shaft extends through the shaft hole. The drive shaft is fixed to the movable iron core. The coil generates a magnetic force to move the movable iron core in the moving direction. The stopper is connected to the drive shaft. The stopper restricts a movement of the movable iron core with respect to the drive shaft in the moving direction.

Abstract: An electromagnetic relay includes a fixed contact, a movable contact, a movable contact piece, a case, and an adhesive material. The movable contact is disposed to face the fixed contact. The movable contact piece is connected to the movable contact. The movable contact piece is movable between a closed position in which the movable contact is in contact with the fixed contact and an open position in which the movable contact is separated from the fixed contact. The case accommodates the fixed contact and the movable contact. The adhesive material is disposed in the case. The adhesive material captures foreign matter in the case.

Abstract: An electromagnetic relay includes a fixed terminal, a fixed contact, a movable contact, a movable contact piece, and a dust collecting mechanism. The fixed contact is connected to the fixed terminal. The movable contact faces the fixed contact. The movable contact piece is connected to the movable contact. The movable contact piece is movable between a closed position at which the movable contact is in contact with the fixed contact and an open position at which the movable contact is separated from the fixed contact. The dust collecting mechanism is disposed adjacent to the fixed contact and the movable contact. The dust collecting mechanism generates a second negative pressure greater than a first negative pressure generated between the fixed contact and the movable contact when the movable contact piece moves from the closed position to the open position.

Abstract: An electromagnetic relay includes a contact case, a first fixed terminal, a movable contact piece, a magnet and a magnet holding member. The first fixed terminal is held by the contact case. The first fixed terminal includes a first fixed contact. The movable contact piece includes a first movable contact disposed to face the first fixed contact. The magnet is disposed apart from the contact case for generating a magnetic field inside the contact case. The magnet holding member is a separate member from the contact case and holds the magnet.

The first fixed terminal includes a first fixed contact. The movable contact piece includes a first movable contact disposed to face the first fixed contact. The contact case includes a first fixed contact and a movable contact piece. The magnet generates a magnetic field inside the contact case. The magnet holding member is comprised of resin. The magnet holding portion includes a flexible portion. The magnet holding member holds the magnet as the flexible portion deforms.

Abstract: A power relay having terminal tabs includes an on-off contact element having at least one movable contact and at least one stationary contact, an on-off drive element, at least two pairs of input/output terminal tabs, and at least one pair of control terminal tabs. The on-off drive element makes the movable contact come into contact with or separated from the stationary contact. The two pairs of input/output terminal tabs are electrically connected to at least one pair of input/output portions of the on-off contact element. The one pair of control terminal tabs is electrically connected to control terminal portions of the on/off drive element. Each of the input/output portions is electrically connected to two of the input/output terminal tabs, which are arranged side-by-side in their thickness direction and in vicinity with each other. The input/output terminal tabs and the control terminal tabs have a same thickness and width.
