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： An electromagnetic contactor where an interphase partition wall (17) is provided between adjacent main contact points (3). A concave portion (23) is provided in an inner wall face of the interphase partition wall (17) so as to be positioned in the middle in discharge paths (indicated by arrows) of arc gas produced by on/off operation of each main contact point (3). Providing the concave portion (23) causes arc gas heading from an arc generation point toward a discharge window (20) to be held in the concave portion (23) as a drifting place, reducing discharge speed of the arc gas. This results that an amount of heat diffused by heat transfer from the arc gas to the interphase partition wall (17) is increased, so that the temperature of arc gas jetted from the discharge window (20) is lowered. Consequently, damage in distribution cables and melting of the interphase partition wall (17) caused by overheating of a main terminal (6) to which arc gas is blown are prevented from occurring.
摘要翻译：一种电磁接触器，其中在相邻的主触点（3）之间提供相间分隔壁（17）。在相间分隔壁（17）的内壁面上设置有凹部（23），以便位于由每个主触点的接通/断开操作产生的电弧气体的放电路径（由箭头表示）的中间点（3）。通过设置凹部（23），从电弧产生点朝向放电窗（20）的电弧气体作为漂移位置被保持在凹部（23）内，从而降低了电弧气体的放电速度。这导致从电弧气体传递到相间分隔壁（17）的热量扩散的热量增加，使得从放电窗口（20）喷射的电弧气体的温度降低。因此，防止了由于吹到电弧气体的主端子（6）的过热而引起的配线电缆的损坏和相间分隔壁（17）的熔化。
