摘要： An electromagnetic relay includes a casing having a housing space open to an external to the casing through an opening. A base is joined to the casing to close the opening. A coil, a pair of fixed contact elements and a pair of movable contact elements are housed in the housing space. A vent hole set to a dimension making it possible to extinguish flame passing therethrough is formed in a portion where the casing and the base are joined together.

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： An electromagnetic relay includes a mobile component movable at time of energization and de-energization of a coil, and a fixed component immovable at the time of energization and de-energization of the coil. A damping space is provided between the mobile component and the fixed component and changes in volume with the movement of the mobile component. A gap provided between the mobile component and the fixed component serves as a passage that allows gas to flow into or out of the damping space when the damping space changes in volume. A size of the gap is set such that a pressure is generated in the damping space to cause a damping force acting on the mobile component when the damping space changes in volume.

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.
