ELECTROMAGNETIC CONTACTOR |
| 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. |
