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 solenoid device includes at least one electromagnetic coil for generating a magnetic flux when energized, a fixed core constituting part of a magnetic circuit through which the magnetic flux passes, and plungers constituting the magnetic circuit together with the fixed core and configured to advance to and retract from the fixed core depending on whether the magnetic coil is energized or de-energized. The magnetic circuit is provided with a magnetic resistance part as a resistance for the magnetic flux. The plungers are configured to be attracted to the fixed core by energizing the electromagnetic coil.

摘要： An electromagnetic relay according to the present disclosure includes an excitation coil generating a magnetic field during energization, a movable core driven by the magnetic field generated by the excitation coil, a movable element including a movable contact and moving to follow the driven movable core, a plurality of stationary terminals each including a stationary contact that contacts the movable contact during the energization of the excitation coil, a stationary yoke formed of a magnetic material and supported by at least one of the plurality of stationary terminals, and a movable yoke formed of a magnetic material and arranged to face the stationary yoke, the movable yoke being in contact with the movable element and moving together with the movable element. Since the stationary yoke is supported by the stationary terminal, increase in temperature of the stationary terminal can be limited.
