摘要: The present invention prevents an arc generated in a main contact unit from entering a space between the main contact unit and a cover plate and an insulating case and coming into contact with the auxiliary terminal. A contact device includes a main contact mechanism including a pair of main stationary contact members (11A), (11B) and a main movable contact member (12) ; an auxiliary contact mechanism disposed at a position different from that of the main contact mechanism and including auxiliary stationary contact members (21A to 21D) and auxiliary movable contact members (22A), (22B); a movable shaft (40) configured to operate the main movable contact member and the auxiliary movable contact member in conjunction with each other; rod-shaped auxiliary terminals (31A to 31D) electrically connected to the auxiliary stationary contact members; a cover plate (8) having holes (32A to 32D) through which the auxiliary terminals penetrate; an insulating case configured to house the main contact mechanism and the auxiliary contact mechanism and including an auxiliary terminal case section (34) configured to separate the main contact mechanism and the auxiliary contact mechanism from each other; and a cylindrical body (7) covering the insulating case exteriorly and joined to the cover plate, wherein fitting portions fitted with each other are formed in junction sections of the cover plate (8) and the auxiliary terminal case section (34).

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 32 that opens and closes a contact by using DC excitation of a coil, a lower case 13 that accommodates the electromagnet 32, external coil terminals 21 and 22 that are disposed in the lower case 13 beside the electromagnet 32, and a substrate 33 that is accommodated in the lower case 13, and that has a rectifier circuit whose input side is connected to the external coil terminals 21 and 22 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 13 has a groove 47 between the electromagnet 32 and the external coil terminals 21 and 22. The substrate 33 is held by being inserted into the groove 47.-
