摘要： There is provided an electromagnetic contactor which can easily and inexpensively change the DC operation type to the AC operation type. The electromagnetic contactor includes an electromagnet that opens and closes a contact by using DC excitation of a coil, a lower case that accommodates the electromagnet, external coil terminals that are disposed in the lower case beside the electromagnet, and a substrate that is accommodated in the lower case, and that has a rectifier circuit whose input side is connected to the external coil terminals and whose output side is connected to the coil so as to output a DC after converting an input AC to the DC. An inner surface of the lower case has a groove between the electromagnet and the external coil terminals. The substrate is held by being inserted into the groove.

摘要： The electromagnetic contactor includes a contact device having a pair of fixed contacts disposed to maintain a predetermined distance and a movable contact disposed so as to be attachable to and detachable from the pair of fixed contacts; an electromagnet unit having a movable plunger that moves the movable contact of the contact device; a hermetic chamber enclosing the pair of fixed contacts, the movable contact, and the movable plunger; an external receptacle that covers the hermetic chamber and electromagnet unit; and a sound insulating resin layer injected and hardened between the hermetic chamber and external receptacle. The electromagnetic contactor reduces the height of a contact device, and thus reduces a size of the electromagnetic contactor, while suppressing electromagnetic repulsion force generated between a movable contact and fixed contacts.
