The multistable self-locking energy-saving relay comprises a wire inlet terminal, a wire outlet terminal, a contact assembly and a magnetic circuit mechanism which are arranged on a shell, the magnetic circuit mechanism comprises a magnet yoke, a bidirectional coil structure, an iron core, a driving rod and a permanent magnet, and the iron core and the driving rod are movably arranged in a guide cavity in the bidirectional coil structure and form linkage fit; the iron core reciprocates under the action of two magnetic field forces with opposite directions generated by the bidirectional coil structure, so that the two bridge-type moving contacts are driven by the driving rod to be in contact with or separated from the two static contacts; according to the relay adopting the technical scheme, the terminal assembly, the contact assembly and the magnetic circuit mechanism are designed into a whole by reasonably optimizing the structural layout, two groups of control loops can be controlled in a linkage manner only by using one coil, the product size is reduced, the cost is saved, and the relay has a bistable magnetic holding function, is short in power-on time and high in response speed and is suitable for popularization and application. And a good energy-saving effect is achieved.
本发明公开了一种多稳态自锁节能继电器,包括设置于壳体的进线端子、出线端子、接触组件和磁路机构,磁路机构包括磁轭、双向线圈结构、铁芯、驱动杆和永磁铁,铁芯与驱动杆活动设置于双向线圈结构内部的导向空腔中并形成联动配合,铁芯受到双向线圈结构产生的两个方向相反的磁场力作用下做往复运动,从而通过驱动杆带动两个桥式动触头与两个静触头实现接触或分离,采用本技术方案的继电器通过合理优化结构布局将端子组件、接触组件和磁路机构设计为一体,只要使用一个线圈即可联动控制两组控制回路,缩小产品体积,从而节约成本,并具备双稳态磁保持功能,通电时间短,响应速度快,具有很好的节能效果。
