Description
Technical field
The utility model is related to buckle releaser field, especially a kind of multifunction structure type lever buckle releaser.
Background technology
The pushing mechanism of electric shock leakage circuit breakers has two kinds of forms：One kind is pushed with relay, i.e., using sensitive relay
Device pushes the breaking coil of breaker；Another kind is that buckle releaser pushes, i.e., pushes a mechanical linkage formula machine with leakage tripping device
Tool enlarger drives switch mechanism movement；And leakage tripping device type divides clapper-type and release type two kinds of forms.It is existing de-
It detains device magnetizer and the air gap of armature contact portion is larger, therefore sensitivity is poor；Also, the shell of existing buckle releaser cannot be kept away
Exempt from the interference of external magnetic field, volume is also larger.
Utility model content
The technical problems to be solved in the utility model is：A kind of multifunction structure type lever buckle releaser is provided, using wide
It is general, it is versatile, suitable for it is a variety of touch, leakage circuit breakers is used cooperatively.
Technical solution is used by the utility model solves its technical problem：A kind of multifunction structure type lever is threaded off
Device, including shell, upper cover plate, contact pin, coil and magnet, the shell is equipped with upper cover plate, and enclosure side is equipped with coil,
Opposite side is equipped with magnet, coil top connecting contact pin, the coil and magnet and is connected by intermediate magnetizer, below magnetizer
Equipped with armature, armature bottom is equipped with the mandril for stretching out shell, and the armature is connected with magnet by spring；The magnet is equipped with
Spring bracing, spring one end connecting spring supporting rack, other end connection armature；The magnet, magnetizer and armature composition
Flux closure circuit；The contact surface air-gap-free of the magnetizer and armature；The shell is can shield outside the shielding of external magnetic field
Shell.
Further, coil described in the utility model is fixedly connected inside the shell by coil rack.
It further says, spring bracing described in the utility model is fixedly connected on by rivet on magnet；The riveting
Nail is through spring bracing, magnet and magnetizer.
The beneficial effects of the utility model are：Magnetizer and armature contact portion, after Precision Machining is ground, make surface
Air gap very little, magnetic loop magnetic resistance very little, due to the suction of permanent magnet and antagonistic spring active force all very littles, and close to flat
Weighing apparatus, therefore smaller exciting current is just enough to discharge armature, so sensitivity is higher；Shell uses high shielding material, avoids
The interference of external magnetic field, and buckle releaser volume reduces 1/3 compared with original volume, easier for installation, versatility greatly improves.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the preferred embodiment of the utility model；
In figure：1. upper cover plate, 2. spring bracings, 3. rivets, 4. magnet, 5. springs, 6. armature, 7. mandrils, 8. magnetic conductions
Body, 9. coil racks, 10. coils, 11. shells, 12. contact pins.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing and preferred embodiment.These attached drawings are letter
The schematic diagram of change, only illustrates the basic structure of the utility model in a schematic way, thus its only show it is related with the utility model
Composition.
A kind of multifunction structure type lever buckle releaser as shown in Figure 1, including shell 11, upper cover plate 1, contact pin 12, line
Circle 10 and magnet 4, shell 11 are equipped with upper cover plate 1, and 11 interior side of shell is equipped with coil 10, and opposite side is equipped with magnet 4, coil
10 top connecting contact pins 12, coil 10 and magnet 4 are connected by intermediate magnetizer 8, and 8 lower section of magnetizer is equipped with armature 6, armature
6 bottoms are equipped with the mandril 7 for stretching out shell, and the armature 6 and magnet 4 are connected by spring 5, and coil 10 is solid by coil rack 9
Surely it is connected in shell 11, magnet 4 is equipped with spring bracing 2,5 one end connecting spring supporting rack 2 of spring, other end connection rank
Iron 6, spring bracing 2 are fixedly connected on by rivet 3 on magnet 4, and rivet 3 runs through spring bracing 2, magnet 4 and magnetizer
8。
Magnet 4, magnetizer 8, armature 6 form flux closure circuit, when anti-magnetized coil passes to the pulse voltage signal of setting
When, reach magnetic loop local demagnetization, discharge armature 6, push mandril 7, reach the disconnection of actuating mechanism；When on anti-magnetized coil
After pulse voltage signal disappears, mandril 7 withstands in mechanism, and armature 6 and magnetizer 8 is allowed to be closed again, forms flux closure circuit
The buckle releaser magnetizer of this structure and armature contact portion after Precision Machining is ground, make surface air gap very little,
Magnetic loop magnetic resistance very little, it is high that buckle releaser is attracted stability；Sheathing material uses high shielding material, avoids being interfered by external magnetic field,
Make buckle releaser stability high；This buckle releaser uses extensively, versatile, suitable for being used cooperatively for a variety of leakage circuit breakers.
Only specific embodiment of the present utility model described in description above, various illustrations are not to this practicality
Novel substantive content is construed as limiting, and person of an ordinary skill in the technical field can be to former institute after specification has been read
The specific embodiment stated is made an amendment or is deformed, without departing from the spirit and scope of utility model.
