Direct current contactor

Abstract

A DC contactor includes a magnetic pole piece, a pushing rod assembly penetrating through the magnetic pole piece, and a movable contact plate mounted on the pushing rod assembly. The pushing rod assembly is configured to drive the movable contact plate to move for making or breaking contact of the DC contactor. The magnetic pole piece is provided with a first limiting structure; the pushing rod assembly is provided with a second limiting structure; and the first limiting structure and the second limiting structure cooperate to restrict rotational movement of the pushing rod assembly. The present disclosure restricts rotational degrees of freedom of the pushing rod assembly through cooperative interaction between the first limiting structure disposed on the magnetic pole piece and the second limiting structure disposed on the pushing rod assembly.
