Device for relay and relay

The invention relates to a device for a relay and the relay. The device comprises a static contact; the movable contact piece can be in contact with the static contact; the lower armature is fixedly connected with the movable contact piece; the upper armature is positioned above the lower armature; the support defines a hollow part, and the movable contact piece and the lower armature penetrate through the hollow part; the upper armature is connected with the support and can move in the vertical direction relative to the support. According to the device for the relay, the distance between the upper armature and the lower armature is shortened through movement of the upper armature in the support, and the short-circuit current resisting capacity of the relay can be improved. 本发明涉及一种用于继电器的装置和一种继电器，包括：静触头；动触片，所述动触片与所述静触头可接触；下衔铁，所述下衔铁与所述动触片固定连接；上衔铁，所述上衔铁位于所述下衔铁上方；以及支架，所述支架限定中空部，所述动触片和所述下衔铁穿过所述中空部；其中，所述上衔铁与所述支架联接并且相对于所述支架沿上下方向可移动。本发明提供的一种用于继电器的装置通过上衔铁在支架内的移动缩短上下衔铁之间距离，可用来提高继电器抵抗短路电流的能力。
