Electromagnetic contactor |
| 摘要 |
In an electromagnetic contactor, an arc generated when a movable contact separates from fixed contacts can be easily extinguished. The movable contact is disposed so as to be connectable to and detachable from the pair of fixed contacts disposed to maintain a predetermined interval inside a contact housing case having insulating properties, and an arc extinguishing chamber is formed in a position in which the movable contact and the pair of fixed contacts contact. At least the inner wall surface side of the arc extinguishing chamber contacting an arc is formed of a high thermal conductivity material having thermal conductivity higher than that of a synthetic resin molded material. |

1. An electromagnetic contactor, comprising:
a contact housing case having an insulating property, a pair of fixed contacts and a movable contact disposed so as to be connectable to and detachable from the pair of fixed contacts, with a predetermined interval therebetween, and disposed inside the contact housing case, and an arc extinguishing chamber formed inside the contact housing case at a position where the movable contact and the pair of fixed contacts contact, wherein at least an inner wall surface of the arc extinguishing chamber contacting an arc is formed of a high thermal conductivity material having thermal conductivity higher than that of a synthetic resin molded material. |
