Document Type and Number:
WIPO Patent Application WO/2018/223733
Kind Code:
A1
Abstract:
Disclosed is a one-input four-output type double-path magnetic latching relay capable of cutting off a neutral wire and a live wire simultaneously, comprising two control loops and a magnetic circuit system. Each control loop is composed of a movable spring seat and a static spring seat, and the static spring seat of one of the control loops is connected to a first pin, and the movable spring seat of the control loop is connected to a fourth pin; the static spring seat of the other control loop is connected to a second pin, and the movable spring seat of the control loop is connected to a third pin; and the first pin and the second pin are connected to a set of neutral wires, and the third pin and the fourth pin are connected to a set of live wires, and the set of live wires and the set of neutral wires form a loop that can cut off the live wires and the neutral wires simultaneously. The magnetic circuit system is laterally disposed in the magnetic latching relay, and the magnetic circuit system is disposed perpendicular to each of the movable spring seats and the static spring seats; and the magnetic circuit system pushes a movable spring seat in each control loop simultaneously via a push piece so as to control opening/closing of the movable spring seat. The invention has higher universality, and a movable spring piece uses a bending design to make contact control more flexible.
