Characterized by: when the coil led to forward pulse voltage, the suction effect that the yoke produced at the coil in the motion made two lower faces and permanent magnet laminating of yoke in the motion down, and two permanent magnets provide a confining force through two lower faces of yoke in moving, form relatively stable magnetic loop, and the relay can keep at the closure state under the confining force of permanent magnet acts on, when relay coil receives a revertive pulsing voltage, make two last faces and permanent magnet laminating of yoke in the motion, two permanent magnets provide a confining force through two last faces of yoke in moving, reform stable magnetic force return circuit, withdraw the back at the voltage that the coil of relay was applyed, and the relay can keep at off -state under the confining force effect of permanent magnet.
Description
Technical field
The utility model relates to magnetic latching relay field, particularly relates to a kind of magnetic latching relay structural system.
Background technology
At present, common magnetic latching relay, its structure generally comprises pedestal, solenoid, permanent magnet and two are positioned at the yoke at pedestal two ends, are provided with cursor between two yokes, pedestal side is provided with movable contact spring and static contact spring piece, and cursor drives movable contact spring action by intermediate mass.When solenoid passes to the pulse current of different directions, its electromagnetic force produced makes cursor rotate, and drives contiguous block and movable contact spring to swing, the contact realizing static contact spring piece and movable contact spring be separated, thus control the closed of external circuit and disconnect.Existing magnetic latching relay in use, because the magnetic confining force of permanent magnet is limited, the movable contact spring of contact system and the contact force of static contact less, often need to set up auxiliary movable contact spring or shell fragment to increase contact force.Nonetheless, sometimes due to the impact of the vibrations in the course of work or other reason, magnetic latching relay is still likely difficult to keep stablizing good contact condition.
Summary of the invention
The purpose of this utility model is to provide magnetic latching relay structural system.
In order to achieve the above object, the utility model adopts following technical pattern: it is critical piece composition that magnetic latching relay structural system comprises yoke, permanent magnet, coil and coil brace in the outer yoke of two side symmetries, motion.It is characterized in that: when coil leads to direct impulse voltage, under the suction that in motion, yoke produces at coil, move upward to making yoke generation straight line in motion, lower two faces, place of yoke in motion and permanent magnet are fitted, as the structural representation of the closure state of Fig. 2, two permanent magnets provide a confining force by lower two faces, place of yoke in motion, form metastable magnetic loop, after the voltage applied at the coil of relay is cancelled, relay can remain on closure state under the confining force effect of permanent magnet; When relay coil is subject to a reverse impulse voltage, under suction (downwards) effect that in motion, yoke produces at coil, upper two faces, place of yoke in motion and permanent magnet are fitted, as the structural representation of the off-state of Fig. 3, two permanent magnets provide a confining force by upper two faces, place of yoke in motion, again form stable magnetic force loop, after the voltage applied at the coil of relay is cancelled, relay can remain on off-state under the confining force effect of permanent magnet; The outer yoke of two side symmetries of the present utility model and coil brace are metastable stationary state, and be support by coil brace, make the gap of meeting yoke in place and motion of the outer yoke of two side symmetries, ensure that in motion, yoke moves up and down under smooth and easy condition in an installation, and control in minimum gap to reduce the loss of magnetic force in magnetic force loop.
The utility model compared to existing technology tool has the following advantages: conventional elastic piece designs, it is no matter the straight chip of non-bending, or shell fragment bendable, due to the impact by contact position and contact sizes, the elastic force design of shell fragment has some limitations, the utility model provides the structural system adding epistasis, makes the control electric current of magnetic latching relay reach maximization, can further increase the stability of whole magnetic latching relay.
