    摘要： Provided is an electromagnetic contactor such that an arc generated when a movable contact separates from fixed contacts can be easily extinguished. A movable contact (130) is disposed so as to be connectable to and detachable from a pair of fixed contacts (111),(112) disposed maintaining a predetermined interval inside a contact housing case (102) having insulating properties and an arc extinguishing chamber (145), (146) is formed in positions in which contacts of the pair of fixed contacts and contacts of the movable contact come into contact, and at least the inner wall surface side of the arc extinguishing chamber that comes into contact with an arc is formed of a high thermal conductivity material having thermal conductivity higher than that of a synthetic resin molded material.

    摘要： There is provided an electromagnetic contactor with which it is possible to suppress electromagnetic repulsion forces which cause a movable contact to open when current is conducted without any effect of magnetic fields of external connection conductors. The electromagnetic contactor includes a contact mechanism (CM) including a pair of fixed contacts (2), interposed in a current conduction path, which have their respective fixed contact portions (2a), (2b) and a movable contact 3 having a pair of movable contact portions (3b), (3c) which are able to come into and out of contact with the pair of fixed contact portions, wherein at least one of the pair of fixed contacts or movable contact is formed in a shape such as to form magnetic fields which generate Lorentz forces opposing electromagnetic repulsion forces generated in an opening direction between the fixed contact portions and movable contact portions when current is conducted. Also, the attachment direction of fixed portions (22), (23), each of which, having an external connection conductor (20), (21) connected to an external connection terminal (2i), (2j) of the corresponding fixed contact 2, is attached to the external connection terminal of the external connection conductor, is set so as to cross the direction of current flowing through the movable contact.

    摘要： There is provided a contact device, and an electromagnetic switch in which the contact device is used, such that an arc generated between a fixed contact and a movable contact when the contacts are opened can be easily extinguished. The contact device includes a pair of fixed contacts (111), (112) fixedly disposed maintaining a predetermined interval inside an arc extinguishing chamber (102) and a movable contact (130) disposed so as to be connectable to and detachable from the pair of fixed contacts inside the arc extinguishing chamber (102), wherein a first arc root movement promotion portion (118b), (118c) that promotes movement in a direction away from the movable contact of the root of an arc generated when the contacts are opened and the movable contact moves away is formed on each of the pair of fixed contacts, and a second arc root movement promotion portion (130b), (130c) that promotes movement in a direction away from the relevant fixed contact of the root of an arc generated when the contacts are opened and the movable contact moves away from the pair of fixed contacts is formed on the movable contact (130).
