Problems solved by technology

During the opening and closing process of the reed contact unit, due to the fusion of the contacts due to the switching load, the adhesive force between the contacts will have an adverse effect on the disconnection of the reed contact unit, and even cause the relay to fail to work normally in severe cases. disconnection, greatly reducing the working reliability of the relay

Abstract

The invention discloses a rectangular rotary armature component for increasing rotatory inertia for a magnetic latching relay. The armature component is I-shaped integrally, and comprises a housing provided with a rotary shaft, a mass block for increasing a rotatory inertia moment, as well as a permanent magnet and an armature which are mounted in the housing, wherein the mass block is far away from the rotary shaft on the housing and is arranged on the housing. The armature component is novel in design and reasonable in structure; the mass block is additionally arranged on the housing, so that a rotatory inertia moment of the armature component can be increased, and the inertia of the armature component can further be increased; in a relay breaking process, the larger rotatory motion inertia of the armature component can increase a breaking force to a large extent for breaking cohered connection points; the working reliability of the relay can be improved; and an opening and closing switching motion process of the relay is more stable due to the increase of the weight of the armature component.

Description

technical field [0001] The invention relates to an armature assembly of a magnetic latching relay, in particular to a rotary armature assembly for a magnetic latching relay with increased rotational moment of inertia. Background technique [0002] Magnetic latching relay is a kind of closed or open state which is only held by the magnetic force generated by the permanent magnet in the coil magnetic circuit system. The mutual conversion between closed and open states only depends on a certain width of forward or reverse DC pulse voltage After the coil in the coil magnetic circuit system is excited, the armature assembly is moved to complete the electrical control device for opening and closing the reed contact unit. [0003] There is a magnetic latching relay of a rotating armature assembly, which controls the forward or reverse rotation of the armature assembly through the coil magnetic circuit system, thereby prompting the reed contact unit to close or open, and realize the...
