摘要： An alternating current contactor comprises a base and a magnetic yoke. The magnetic yoke is mounted on a bottom plate of the base. A magnetic yoke support for supporting and buffering the magnetic yoke is respectively provided at two sides of the magnetic yoke, wherein sidewalls at two sides of each magnetic yoke support, which are connected with the magnetic yoke are different in thickness. The magnetic yoke support of the alternating current contactor of the utility model has a simple structure due to the arrangement of an asymmetric eccentric structure. The up-down position of the magnetic yoke relative to the bottom plate of the base can be adjusted by changing an assembly direction of the magnetic yoke supports, thereby achieving the purpose of adjusting the total stroke of the product with high flexibility. When a dimension of a housing of a plastic part is abnormal, the magnetic yoke has a certain adjustment amount to ensure that the integral assembly of the product can be completed and the efficiency and reliability can be improved.

摘要： An electromagnetic contactor includes a contact mechanism including a pair of fixed contacts having fixed contact portions and interposed in a current conduction path, and a movable contact having a pair of movable contact portions capable of contacting to and separating from the pair of fixed contact portions. At least one of the pair of fixed contacts or the movable contact is formed in a shape to form magnetic fields generating Lorentz forces opposing electromagnetic repulsion forces generated in an opening direction between the fixed contact portions and the movable contact portions when current is conducted. External connection conductors are connected to external connection terminals of the fixed contacts, an attachment direction of fixed portions fixed to the external connection terminal of the fixed contacts is set to cross a current flow direction flowing through the movable contact.
