Background technology
Circuit breaker is as a kind of contactor, obtained using widely because of it can transship at circuit, carry out reliable protection under the short circuit, situation such as under-voltage.Circuit breaker generally comprises moving contact, fixed contact, operating mechanism and release, when killer switch needs closure, promoting operating mechanism by external force contacts moving contact and fixed contact, and it is locked together in together by corresponding locking mechanism, circuit breaker just is in "on" position, circuit communication like this.Break down in the ifs circuit, then release acts on locking mechanism with generation it is thrown off, then moving contact under the effect of retracting spring and the rapid disjunction of fixed contact, circuit disconnects.
According to the difference of protective effect, be provided with unit such as heat protection release unit, short-circuit release unit in the circuit breaker.Heat protection release unit mainly comprises a bimetal leaf; this bimetal leaf heating when electric current passes through this bimetal leaf; because the material difference of two sheet metals; therefore the bimetallic sector-meeting produces flexural deformation; after bending to a certain degree, will act on the locking mechanism, make locking mechanism throw off circuitry cuts.The short-circuit release unit generally comprises a static iron core and an armature, and the magnetic field force that produces when electric current on the static iron core is enough big can attract armature movement, and armature and then drive locking mechanism are thrown off to cut off circuit.
Being perfectly safe in existing circuit breaker for protective circuit; often to comprise polytype release unit in the release of circuit breaker; but because the structure disunity of dissimilar release unit; so all be being installed in the circuit breaker of comparatively disperseing generally; so just make the mechanism of circuit breaker be not very compact, volume is bigger; and process complex procedures, make production efficiency lower.
The utility model content
At above-mentioned the deficiencies in the prior art; the technical problems to be solved in the utility model provides a kind of release unit and formed release thereof of new structure; this release unit protects release and short-circuit protection release to be integrated into an integrative-structure heat; thereby make release more convenient when mounted, the structure of the circuit breaker that also makes is more compact.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of release unit of circuit breaker, comprise insulating support, bimetal leaf, static iron core and armature, also comprise a conductive plate, described conductive plate comprises a riser portion and a flat part, fixedly connected with the lower end of bimetal leaf in the lower end of described riser portion, described flat part is fixedlyed connected with the bottom surface of insulating support; The side of described insulating support is provided with a cavity volume, and described static iron core is positioned at this cavity volume, and described armature is installed on the insulating support and is relative with static iron core.
Preferably, the upper end of described bimetal leaf is free and be fixed with ejector pin.
Preferably, also comprise a connecting lever spare, connecting lever spare comprises connecting lever, following connecting lever and turning, and its turning is hinged on the insulating support, and following connecting lever is fixedlyed connected with armature, and last connecting lever is connected with a spring, and the other end of spring is fixed on the insulating support.
By the release that above-mentioned a plurality of releases unit forms, the equal one of the insulating support of all release unit links to each other.
Preferably, release comprises three release unit.
Technique scheme has following beneficial effect: this release unit protects release unit and short-circuit protection release unit to be integrated into an integrative-structure heat; make that the structure of release is more compact, small and exquisite; more convenient when mounted, and then also make the structure of circuit breaker more compact, attractive in appearance.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, this release unit comprises insulating support 1, bimetal leaf 2, conductive plate 3, static iron core 4 and armature 5.The side of insulating support 1 is provided with cavity volume 11 (as shown in Figure 3), and static iron core 4 is positioned at cavity volume 11.Conductive plate 3 comprises a riser portion 31 and a flat part 32, fixedly connected with the lower end of bimetal leaf 2 in the lower end of riser portion 31, flat part 32 is fixedlyed connected with the bottom surface of insulating support 1, and the upper end of bimetal leaf 2 is provided with an ejector pin 7, and the upper end of bimetal leaf 2 can be free movable.Armature 5 is connected with insulating support 1 by a connecting lever spare 8, and armature 5 is relative with static iron core 4.Connecting lever spare 8 comprises connecting lever 81, turning 82 and last connecting lever 83, and following connecting lever 81 is connected with armature 5, and turning 82 is hinged with insulating support 1, and last connecting lever 83 is connected with a spring 6, and the other end of spring 6 is connected with insulating support 1.
When this release unit is packed circuit breaker into, conductive plate 3 and static iron core 4 insert the circuit loop of circuit breaker, when the general overload of circuit, can produce certain heat on the conductive plate 3, and with heat transferred bimetal leaf 2, because two sheet material of bimetal leaf 2 are different, bending will deform after bimetal leaf 2 is heated like this, and then ejector pin 7 actions of drive bimetal leaf 2 upper ends, and the locking mechanism that acts on the circuit breaker disconnects circuit breaker.When the serious overload of electric current promptly is short-circuited, electric current on the static iron core 4 sharply becomes big at this moment, produce bigger magnetic field on the static iron core 4, attract armature 5 actions on its opposite, and then armature 5 drives connecting lever 81 motions down, and last connecting lever 83 moves round about and the locking mechanism that acts on the circuit breaker makes the circuit breaker disconnection.After circuit breaker disconnected, armature 5 resetted under the elastic force effect of spring 6.
Please refer to Fig. 4, is a release 9 of being made up of three above-mentioned release unit, and the insulating support of these three release unit connects into as a whole, and this release 9 can be used on the three-phase breaker.Because this release unit protects release unit and short-circuit protection release unit to be integrated into an integrative-structure heat; make that like this structure of this release 9 is more compact, small and exquisite; only need when mounted release directly is contained on the base 10 of circuit breaker and get final product (as shown in Figure 5); very convenient, also make the structure of circuit breaker more compact, attractive in appearance.
More than a kind of release unit that the utility model embodiment is provided and being described in detail by its release of forming; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection range of the present utility model.
