Abstract:
The present invention discloses an opposite arc isolation device of a high voltage direct current relay, including a movable contact assembly and a fixed contact assembly, wherein the movable contact assembly includes a movable spring plate and a left movable contact and a right movable contact fixed at left and right ends of the movable spring plate; the fixed contact assembly includes a left fixed contact corresponding to the left movable contact and a right fixed contact corresponding to the right movable contact; an arc isolation member made of insulating material is provided between the left movable contact and the right fixed contact; the front-to-rear dimension L of the arc isolation member is greater than the front-to-rear width M of a joint surface of the movable contacts with the fixed contacts; and, the arc isolation member has a height H that enables the isolation of opposite arcs between the two sets of movable and fixed contacts.

Claim (Index 4):
The opposite arc isolation device of a high voltage direct current relay according to  claim 2 , wherein the arc isolation member is of a hood-shaped structure; the arc isolation member comprises an arc isolation portion on an upper side and a buckle portion on a lower side; an accommodating chamber is formed within the buckle portion, and the buckle portion has an n-shaped section; the accommodating chamber runs through the buckle portion in an up-down direction, and the accommodating chamber transversely runs through the buckle portion, so that a front fixed portion on the front side of the movable spring plate and a rear fixed portion on the rear side of the movable spring plate are formed on the buckle portion; bosses are formed on lower edges on the inner side of the front fixed portion and the inner side of the rear fixed portion; the positioning notched longitudinally runs through the movable spring plate, and the arc isolation member is fixed to the movable spring plate so that upper edges of the bosses come into contact with a lower edge of the movable spring plate and a lower edge of the arc isolation portion comes into contact with an upper edge of the movable spring plate.
