Abstract
The invention discloses a technical solution of a magnetic latching relay structured system. The magnetic latching relay structured system comprises symmetrical outer yokes on two sides, a moving inner yoke, permanent magnets, a coil and a coil brace which serve as main components. The magnetic latching relay structured system is characterized in that when a forward pulse voltage is introduced into the coil, the two lower surfaces of the moving inner yoke are attached to the permanent magnets under the attraction of the coil, the two permanent magnets provide a retention through the two lower surfaces of the moving inner yoke to form a relatively stable magnetic circuit, and the relay can be kept in a closed state under the retention of the moving inner yoke; and when the coil of the relay is subjected to a reverse pulse voltage, the two upper surfaces of the moving inner yoke are attached to the permanent magnets, the two permanent magnets provide a retention through the two upper surfaces of the moving inner yoke to form a stable magnetic circuit again, and after the voltage applied to the coil of the relay is revoked, the relay can be kept in an open state under the retention of the permanent magnets.
Description
Technical field
The present invention relates to magnetic latching relay field, particularly relate to a kind of technical scheme 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 object of this invention is to provide magnetic latching relay structural system.
In order to achieve the above object, the present invention 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 invention 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 present invention 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 invention provides the structural system adding epistasis, make the control electric current of magnetic latching relay reach maximization, the stability of whole magnetic latching relay can be further increased.
