Abstract
The utility model discloses a breaker or a switch, which comprises a release piece of a tipping device, an armature, a magnet yoke, an oil cup and a coil matched with the oil cup. The breaker or the switch is characterized in that the armature and the magnet yoke are completely separated and do not contact, the armature is arranged on the corresponding release piece of the tipping device in the breaker or the switch, partial plane is folded out from a plane or a parallel position of the magnet yoke corresponding to a oil cup pole face to form a magnet yoke pole face, and the minimum distance between the pole face of the armature and the magnet yoke pole face is in a range from 0.3 millimeter to 20 millimeters. Compared with the prior art, the magnet yoke removes knife edges or spindle structures, and partial magnet yoke pole face is folded out from the plane or the parallel position corresponding to the oil cup pole face. The breaker or the switch has the advantages of being less in parts, easy to process, strong in releasing force, stable in performance and the like.
Description
Technical field
The utility model relates to circuit breaker or switch, especially with the circuit breaker or the switch of lubricating cup formula release.
Background technology
Adopt at present lubricating cup formula release with do overcurrent with (or) circuit breaker or the switch of short-circuit protection, its lubricating cup formula release is an electromagnet system that comprises lubricating cup, coil, yoke, armature and back-moving spring etc.Armature is the iron plate of a bending or not bending.Armature connects as one through contacting with modes such as the yoke edge of a knife or rotating shafts, and can be around rotations such as the edge of a knife or rotating shafts.The plane of armature one end is that pole-face is corresponding with the lubricating cup pole-face, and the dropout part of the release in the other end and circuit breaker or the switch is corresponding.When overcurrent or short circuit take place when; This lubricating cup formula circuit breaker or switch are through certain time-delay; The pole-face of armature can be by adhesive, simultaneously around rotations such as the edge of a knife or rotating shafts, armature promote or flap circuit breaker or switch in the dropout part of the release that directly do not link to each other with this lubricating cup release; The release of circuit breaker or switch is threaded off, thereby reach the purpose of power-off protection.After the outage, the back-moving spring that is connected with armature automatically resets armature.
This mode exists that parts are more, the rotating shaft of yoke or armature or shortcoming such as the knife-edge part processing request is higher, tripping force is difficult to improve, performance is stable inadequately.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and a kind of parts are less, processing is simple and easy, tripping force strong, circuit breaker or switch stable performance, band lubricating cup formula release and provide.
The purpose of the utility model is to realize through following technical scheme:
A kind of circuit breaker or switch comprise dropout part, armature, yoke, the lubricating cup of release and the coil that is equipped with it, and different with prior art is: described armature separates with described yoke fully, does not contact; Described armature is arranged on the dropout part of corresponding release in circuit breaker or the switch.
The plane at the corresponding lubricating cup pole-face of said yoke place or parallel position bend out the part plane and form the yoke pole-face.
Minimum range between the pole-face of said armature and the described yoke pole-face is 0.3 ~ 20 millimeter.
Adopt above-mentioned technical scheme, keep lubricating cup, coil and the yoke of the cup type release of crude oil, cancelled back-moving spring; Cancel modes such as the former yoke edge of a knife or rotating shaft, the plane at the corresponding lubricating cup pole-face of yoke place or parallel position bend out the part planar shaped and become pole-face, thereby further increase can improve the adhesive pole-face of dropout suction; Armature separates and does not contact (referring to that armature pole-face and yoke pole-face do not contact before closed because of adhesive) fully with yoke; Directly armature is arranged on the dropout part of release corresponding in circuit breaker or the switch; And the armature pole-face also can suitably increase area, with further increase dropout suction.
Therefore, this circuit breaker or switch have that parts are less, strong, the steady performance of simple and easy, the tripping force of processing.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Among the figure, 1. yoke 2. pads 3. coils 4. yoke pole-faces 5. lubricating cups 6. armature 7. dropout parts.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is done further to set forth, but be not qualification the utility model.
Embodiment:
With reference to Fig. 1, a kind of circuit breaker or switch comprise dropout part 7, armature 6, yoke 1, the lubricating cup 5 of release and the coil 3 that is equipped with it, and coil 3 is arranged on the pad 2, and armature 6 separates with yoke 1 fully, does not contact; Armature 6 is arranged on the dropout part 7 of corresponding release in circuit breaker or the switch.
The plane at yoke 1 corresponding lubricating cup 5 pole-faces place or parallel position bend out the part plane and form yoke pole-face 4.
The pole-face of armature 6 is corresponding with the pole-face and the yoke pole-face 4 of lubricating cup 5.
Minimum range between the pole-face of armature 6 and the yoke pole-face 4 is 0.3 ~ 20 millimeter, to guarantee the reliability of armature 6 adhesives, drive dropout part 7.
When overcurrent or short circuit took place, this lubricating cup formula circuit breaker or switch were through certain time-delay, and armature 6 is by adhesive, and the dropout part 7 that drives release moves together, thereby the release of circuit breaker or switch is threaded off, and reached the purpose of power-off protection.
This circuit breaker or switch keep lubricating cup 5, coil 4 and the yoke 1 of the cup type release of crude oil, have cancelled back-moving spring; Modes such as the yoke 1 former edge of a knife of cancellation or rotating shaft, plane or parallel position at corresponding lubricating cup pole-face place bend out yoke pole-face 4, thus further increase can improve the pole-face of dropout suction; Armature 6 is separated (referring to that armature 6 separates before adhesive with yoke 1 fully, does not contact) from former lubricating cup release, and armature 6 also can suitably increase area, with further increase dropout suction.Adopt armature 6 to be set directly at the mode on the dropout part 7 of corresponding release in circuit breaker or the switch, under the electromagnetic attraction effect, directly drive dropout part 7 and thread off.
This circuit breaker or switch parts are less, processing is simple and easy, dropout suction strong, stable performance.
Claims (3)
1. circuit breaker or switch comprise dropout part, armature, yoke, lubricating cup and the equipped with it coil of release, and it is characterized in that: described armature separates with described yoke fully, does not contact; Described armature is arranged on the dropout part of corresponding release in circuit breaker or the switch.
2. circuit breaker according to claim 1 or switch is characterized in that: the plane at the corresponding lubricating cup pole-face of said yoke place or parallel position bend out the part plane and form the yoke pole-face.
