ELECTROMAGNETIC CONTACTOR

摘要

An electromagnetic contactor with connecting spring including: a movable core contact plate section that is inserted into a through hole formed in a movable core and comes into contact with a contact support side of the through hole; and a pair of curved plate sections each joined to either end of the movable core contact plate section and housed in connecting spring tip housing sections formed in the contact support, the sides of which opposite to a contact surface of the movable core contact plate section come into contact with the connecting spring tip housing sections. In the movable core contact plate section, a depressed section is formed in a direction crossing a longitudinal direction to bulge out to an opposite side to the contact support side is formed, and contact sections that come into contact with the through hole are formed on both ends of the depressed section.

主权项

1. An electromagnetic contactor comprising:
an AC electromagnet having a fixed core and a movable core; a contact support that aligns and holds a plurality of movable contacts; and a connecting spring that connects the movable core of the AC electromagnet and the contact support, wherein the connecting spring includes: a movable core contact plate section that is inserted into a through hole formed in the movable core and comes into contact with the contact support side of the through hole; and a pair of curved plate sections that are each joined to either end of the movable core contact plate section and housed in connecting spring tip housing sections formed in the contact support, the pair of curved plate sections coming into contact with the connecting spring tip housing sections on sides opposite to a contact surface of the movable core contact plate section, and wherein, in the movable core contact plate section, a depressed section that is formed in a direction crossing a longitudinal direction of the movable core contact plate section and bulges out to an opposite side to the contact support side is formed, and a pair of contact sections that individually come into contact with the through hole are formed on both ends of the depressed section.
