Abstract
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.
Claims15
A contact device, comprising:
- a stator comprising a pair of spaced and parallel rod-shaped members with parallel longitudinal axes;
- a mover having a stator facing surface facing a side surface of each of the pair of rod-shaped members;
- a housing configured to support the stator and house the mover;
- and
- a yoke (1) fixed to the housing, (2) having a facing surface that faces the stator facing surface of the mover and (3) containing a soft magnetic material, wherein
- the yoke (1) is asymmetrical in a direction parallel to the longitudinal axes of the pair of rod-shaped members and (2) is between the pair of rod-shaped members in a direction perpendicular to the longitudinal axes, and
- the yoke and the mover are configured such that the yoke provides a magnetic path for a magnetic field generated around the mover by current flowing through the mover.
