Abstract
The utility model discloses a magnetic hold relay with a symmetric transmission type structure, comprising a push part. The push part comprises an armature part, a transmission piece and a push clamp, wherein one end of the transmission piece is clamped in a clamping groove at one end of the push clamp, and the other end of the push clamp is matched with a movable spring assembly. The transmission piece enters a reset state from a relay operation state by passing through the clamping groove of the push clamp matched with the transmission piece and rotates on a midpoint of displacement in an effective movement direction by taking any point on a straight line vertical to the effective movement direction as an axis. A rotation shaft is arranged at the axis and is positioned on a shell. The other end of the transmission piece is partially matched with the armature. After adopting the structure, for cantilever type rotation magnetic circuits, the problem that mechanical parameters are imbalanced under the operation and the reset states as the push clamp is displaced in an ineffective movement direction when the relay is in operation and reset states so that the stability of the product performance is enhanced; and for direct-acting magnetic circuits, the relationship between the capacity and the volume of the relay can be solved so that the product structure is more compact and the performance is more stable.
