Abstract
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.
Claims5
An electromagnetic relay comprising:
- a coil configured to generate a magnetic field by being energized;
- a fixed element including a fixed contact point made of an electrical conductive material;
- a movable element including a movable contact point that is made of an electrical conductive material and disposed to face the fixed contact point in a central axis direction of the coil;
- a fixed core that is made of a magnetic material and disposed inside the coil;
- a movable section disposed between the movable element and the fixed core to move the movable element in the central axis direction in accordance with an energizing state of the coil, the movable section including:
- a movable core that is a rigid body made of an inorganic magnetic material and disposed adjacent to the fixed core in the central axis direction;
- and
- a shaft that is connected to the movable core and extends toward the movable element in the central axis direction, the shaft being a rigid body made of an inorganic material;
- a movable yoke that is made of a magnetic material and connected to the movable element to move together with the movable element in the central axis direction;
- a fixed yoke that is a rigid body made of an inorganic magnetic material and disposed between the movable core and the movable yoke to generate a yoke attracting force between the movable yoke and the fixed yoke upon being energized by a contact between the movable contact point and the fixed contact point;
- and
- a stopper that protrudes from either one of the fixed yoke or the movable section toward the other to be in contact with the other when the movable section moves toward the fixed yoke, the stopper being integrally formed with the either one of the fixed yoke or the movable section.
