摘要： An electromagnetic relay includes a base frame including a main body supporting a fixed element, and a bottom plate having a plate thickness direction in an extending direction orthogonal to a central-axis line direction. An intermediate cover includes a covering plate facing a contact mechanism unit. An outer cover includes a top plate facing the bottom plate across the contact mechanism unit, and a first side plate extending from one end of the top plate and facing the covering plate. A first gap between the covering plate and the bottom plate in the extending direction and a second gap between the covering plate and the top plate in the extending direction are arranged to be substantially symmetric across the covering plate in the extending direction, the first gap and the second gap being on the first side plate.

摘要： An electromagnetic relay includes: a coil; a housing that supports the coil; a non-movable portion supported by the housing and including a fixed core and a fixed magnetic path defining member; and a movable portion provided to be reciprocally movable along a center axis line of the coil according to an energization state of the coil. The movable portion includes a movable core disposed to face the fixed core along the center axis line. The movable portion integrally has a flange portion protruding in a coil radial direction perpendicular to the center axis line to define a separation distance and/or a facing area in a magnetic gap between the fixed magnetic path defining member and the movable core by abutting against the non-movable portion.

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 movable element, a movable yoke, a fixed yoke, a movable section, and a stopper. The movable element includes a movable contact point. The movable yoke is connected to the movable element to move together with the movable element. The movable section includes a movable core made of an inorganic magnetic material and a shaft made of an inorganic material. The fixed yoke is made of an inorganic magnetic material and disposed between the movable core and the movable yoke. The stopper protrudes from either one of the fixed yoke or the movable section toward the other to contact with the other when the movable section moves toward the fixed yoke. The stopper is integrally formed with the either one of the fixed yoke or the movable section.

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.

摘要： An electromagnetic relay includes: an excitation coil; a movable core; a movable contactor that operates by following the movable core; a fixed contactor that is in contact with the movable contactor when the excitation coil is energized; a base that supports the fixed contactor; a fixed yoke fixed to the base; a moving yoke; a first pressing spring that biases the moving yoke toward the movable contactor; and a second pressing spring that biases the movable contactor such that the movable contactor and the fixed contactor are in contact with each other. The moving yoke is disposed to be in contact with a surface of the movable contactor opposite from the fixed contactor and to oppose the fixed yoke through the movable contactor. The moving yoke is provided to be able to contact and separate from the movable contactor.

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 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.
