ELECTROMAGNETIC CONTACTOR

摘要

An electromagnetic contactor capable of coupling either one of an alternating current (AC) electromagnet or a direct current (DC) electromagnet with an identical contact support is provided. The electromagnetic contactor includes an electromagnet including either one of the AC electromagnet (12AC) including a movable core or the DC electromagnet (12DC) including an armature, and a contact support (36) configured to hold plural movable contacts in alignment to be coupled with and driven by the electromagnet. The contact support includes a coupling portion (40) including a movable core contact portion (41), coupling spring edge accommodation portions (46), and armature contact portions (51) arranged on opposite sides with respect to the movable core contact portion of the coupling spring edge accommodation portion. The AC electromagnet (12AC) includes an AC electromagnet coupling spring (56) and the DC electromagnet (12DC) includes a DC electromagnet coupling spring (161).

主权项

1. An electromagnetic contactor comprising:
an electromagnet including either one of an alternating current (AC) electromagnet including a movable core or a direct current (DC) electromagnet including an armature, and a contact support configured to hold a plurality of movable contacts in alignment to be coupled with the electromagnet and driven by the electromagnet, wherein the contact support comprises a coupling portion including, at a coupling face of the electromagnet: a movable core contact portion extending in a direction crossing an alignment direction of the plurality of movable contacts with which a mounting face of the movable core of the AC electromagnet is in contact; coupling spring edge accommodation portions arranged on both sides of the movable core contact portion, and at least the movable core contact portion and one of end parts in an extension direction of the movable core contact portion being opened; and armature contact portions arranged on opposite sides with respect to the movable core contact portion of the coupling spring edge accommodation portion, with which the armature of the DC electromagnet is in contact, wherein the AC electromagnet includes an AC electromagnet coupling spring to be inserted into a through hole arranged on the mounting face of the movable core, and wherein the DC electromagnet includes a DC electromagnet coupling spring arranged at a contact face of the armature to be in contact with the armature contact portion.
