Description
Technical field
The utility model relates to low voltage equipment technical field, especially a kind of release.
Background technology
Release is connected with on breaker mechanical (or form overall), in order to release holding mechanism and the device making circuit breaker automatically disconnect.Existing release is commonly electromagnetic release, and the impact by external disturbing field is large, and de-mouth is unstable, affects normally carrying out of mechanical tripping action to a certain extent.
Utility model content
In order to overcome existing above-mentioned deficiency, the utility model provides a kind of release.
The utility model solves the technical scheme that its technical problem adopts: a kind of release, comprise shell, upper cover plate, contact pin, coil and magnet, shell is provided with upper cover plate, enclosure side is provided with coil, and opposite side is provided with magnet, coil top connecting contact pin, coil is connected by middle magnetic conductor with magnet, be provided with armature below magnetic conductor, be provided with the push rod stretching out shell bottom armature, described armature is connected by spring with magnet.
According to another embodiment of the present utility model, comprise coil further and be fixedly connected with in the enclosure by coil rack.
According to another embodiment of the present utility model, comprise magnet further and be provided with spring bracing, spring one end linking springs bracing frame, the other end connects armature.
According to another embodiment of the present utility model, comprise spring bracing further and be fixedly connected on magnet by rivet.
According to another embodiment of the present utility model, comprise rivet further and run through spring bracing, magnet and magnetic conductor.
The beneficial effects of the utility model are, structure is simple, easy to operate, and working stability is reliable, and hermetically-sealed construction reduces external disturbance, dropout are stablized, effective raising equipment dropout efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. upper cover plates, 2. spring bracing, 3. rivet, 4. magnet, 5. spring, 6. armature, 7. push rod, 8. magnetic conductor, 9. coil rack, 10. coil in figure, 11. shells, 12. contact pins.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of release, comprise shell 11, upper cover plate 1, contact pin 12, coil 10 and magnet 4, shell 11 is provided with upper cover plate 1, the inner side of shell 11 is provided with coil 10, opposite side is provided with magnet 4, coil 10 top connecting contact pin 12, coil 10 is connected by middle magnetic conductor 8 with magnet 4, armature 6 is provided with below magnetic conductor 8, the push rod 7 stretching out shell is provided with bottom armature 6, described armature 6 is connected by spring 5 with magnet 4, coil 10 is fixedly connected in shell 11 by coil rack 9, magnet 4 is provided with spring bracing 2, spring 5 one end linking springs bracing frame 2, the other end connects armature 6, spring bracing 2 is fixedly connected on magnet 4 by rivet 3, rivet 3 runs through spring bracing 2, magnet 4 and magnetic conductor 8.
When after switch connection power supply, if release reaction without exception, switch normal operation, when there is leakage current under line powering low-voltage 50V, produces magnetic field after coil 10 is energized, magnetic field overcomes the pulling force of magnet 4 and spring 5 by magnetic conductor 8, armature 6 and magnetic conductor 8 separately promote push rod 7, and push rod 7 ejects, and release is started working, rivet 3 plays and is well fixedly connected with effect, is stablized by spring bracing 2, magnet 4 and magnetic conductor 8 and is connected.
More than illustrate the utility model just illustrative; and it is nonrestrictive; those of ordinary skill in the art understand; when not departing from the spirit and scope that claims limit; many amendments, change or equivalence can be made, but all will fall in protection range of the present utility model.
