摘要： A stationary core is in an exciting coil. A yoke covers an outer periphery and an axial end of the exciting coil to form a magnetic circuit and has an opening portion. The movable core faces the stationary core through the opening portion and is attracted toward the stationary core on energization of the exciting coil. A return spring urges the movable core against the attraction direction. A first gap is formed between the stationary core and the movable core on deenergization of the exciting coil. A second gap is formed between the yoke and the movable core on deenergization of the exciting coil. The second gap allows the yoke and the movable core to generate an attractive force therebetween on energization of the exciting coil. The return spring is made of a magnetic material to magnetically bridge the first gap or the second gap.

摘要： An electromagnetic relay includes: an exciting coil; a movable core driven by the exciting coil; a movable contactor having a first movable contact and a second movable contact to operate with the movable core; a first fixed terminal having a first fixed contact with which the first movable contact abuts when the movable contactor is moved by energizing the exciting coil; and a second fixed terminal having a second fixed contact with which the second movable contact abuts when the movable contactor is moved by energizing the exciting coil. An inclination angle of a central axis of the first movable contact with respect to a central axis of the first fixed contact and an inclination angle of a central axis of the second movable contact with respect to a central axis of the second fixed contact are inclined in opposite directions from each other.

摘要： An electromagnetic relay has a contact device and an electromagnet device. An electromagnetic relay has stators which are a pair of rod-like members, and a mover. The mover may face the side of the stator. A housing supports the stator and accommodates the mover. A yoke is fixed to the housing so as to face the movable facing surface and contains a soft magnetic material.

摘要： In an electromagnetic relay device, a stationary core is coaxially arranged in an exciting coil, and constitutes a magnetic circuit. A yoke is arranged to surround an outer periphery of the exciting coil and the second end of the exciting coil to constitute the magnetic circuit. The yoke has an opening that is located to be closer to the first end of the exciting coil than to the second end of the exciting coil, and that faces the stationary core. A movable core is located to face the stationary core via the opening. The movable core is pulled to the stationary core upon the exciting coil being energized. A return spring is made of a magnetic member that is volutely wound in an axial direction of the stationary core. The return spring urges the movable core to be separated from the stationary core.

摘要： An electromagnetic coil through which current is passed to generate a magnetic flux, a fixed core, a movable core, a magnetic spring disposed between the cores and, and a yoke are provided. The magnetic spring includes a magnetic substance, and biases the movable core in a direction in which the movable core is separated from the fixed core in a Z direction. Additionally, the magnetic spring includes a leaf spring member including the magnetic substance and spirally wound, and a central portion of the magnetic spring is located biased toward one side in the Z direction compared to a peripheral portion of the magnetic spring. When the movable core is attracted to the access position, the magnetic spring is prevented from being deformed to a minimum spring length corresponding to a width of the leaf spring member.

摘要： A fixed core includes: a fixed core tapered portion having a diameter increased in an attraction direction; and a fixed core circular portion having a fixed outer diameter and extending in the attraction direction from an end of the fixed core tapered portion. A movable core includes a movable core tubular portion in which a movable core hole is defined. The movable core hole is a space into which the fixed core tapered portion and the fixed core circular portion can enter. The movable core tubular portion includes: a movable core cylindrical portion having a constant inner diameter; and a movable core tapered tubular portion having an inner diameter decreased from an end of the movable core cylindrical portion in a non-attraction direction.

摘要： A contact point device includes a first contactor, an oscillation supporting portion, and a second contactor. The first contactor has an outer side surface shaped in a column that surrounds a central axis. The oscillation supporting portion supports the first contactor to allow the central axis to oscillate. The second contactor is disposed opposite to the first contactor. One of the first contactor and the second contactor includes a plurality of first contact portions provided to surround the central axis on a plane perpendicular to the central axis, and the other includes a second contact portion provided to protrude toward a space surrounded by the plurality of the first contact portions. The second contact portion has a contact surface which is a curved surface exposed toward the space to surround the central axis.
