Abstract
The invention discloses a circuit breaker or a switch, comprising a buckle releasing piece of a buckle releasing device, an armature, a magnetic yoke, an oil cup and a coil assembled on the oil cup. The circuit breaker or the switch is characterized in that the armature and the magnetic yoke are completely separated and are not in contact; the armature is arranged on the buckle releasing piece of the corresponding buckle releasing device in the circuit breaker or the switch; a magnetic yoke polar surface is formed by bending one part of a plane of the magnetic yoke corresponding to the plane of an oil cup polar surface or parallel to the plane of an oil cup polar surface; and the minimum distance between the polar surface of the armature and the magnetic yoke polar surface is 0.3-20 mm. Compared with the prior art, the armature does not has a cutter opening or a rotary shaft structure, and the magnetic yoke polar surface is formed by bending one part of the plane of the magnetic yoke corresponding to the plane of the oil cup polar surface or parallel to the plane of an oil cup polar surface. The circuit breaker or the switch has the advantages of fewer parts, easiness in machining, strong buckle releasing force, stable performance and the like.
Description
Technical field
The present invention relates to circuit breaker or switch, especially with circuit breaker or the switch of oil-cup type release.
Background technology
Now adopt the oil-cup type release with do overcurrent and (or) circuit breaker or the switch of short-circuit protection, its oil-cup type 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 by 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 occur when; this oil-cup type 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 the shortcoming such as the knife-edge part processing request is higher, tripping force is difficult to improve, performance is stable not.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, and provide that a kind of parts are less, simple and easy, the tripping force of processing is strong, stable performance, with circuit breaker or the switch of oil-cup type release.
The objective of the invention is to realize by following technical scheme:
A kind of circuit breaker or switch comprise the dropout part, armature, yoke, lubricating cup of release and equipped coil with it, unlike the prior art be: described armature separates fully with described yoke, does not contact; Described armature is arranged on the dropout part of release corresponding in circuit breaker or the switch.
The plane at the corresponding lubricating cup pole-face of described yoke place or parallel position bend out the part plane and form the yoke pole-face.
Minimum range between the pole-face of described 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 former oil-cup type release, cancelled back-moving spring; Cancel the 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 drawings and Examples content of the present invention is further elaborated, but is not limitation of the invention.
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 fully with yoke 1, does not contact; Armature 6 is arranged on the dropout part 7 of release corresponding in circuit breaker or the switch.
The plane at yoke 1 corresponding lubricating cup 5 pole-face places or parallel position bend out the part plane and form yoke pole-face 4.
The pole-face of armature 6 is corresponding with 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 occured, this oil-cup type 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 former oil-cup type release, have cancelled back-moving spring; The 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 fully with yoke 1, 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 mode on the dropout part 7 of release corresponding 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. a circuit breaker or switch comprise the dropout part, armature, yoke, lubricating cup of release and equipped coil with it, and it is characterized in that: described armature separates fully with described yoke, does not contact; Described armature is arranged on the dropout part of release corresponding 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 described yoke place or parallel position bend out the part plane and form the yoke pole-face.
