Description
Technical field
Electrical apparatus release field is the utility model is related to, especially a kind of straight push-and-pull rod-type electrical apparatus release of multifunction structure type.
Background technology
The pushing mechanism of electric shock RCCB has two kinds of forms：One kind is promoted with relay, i.e., using sensitive relay
Device promotes the breaking coil of breaker；Another kind is promoted with electrical apparatus release, i.e., promotes a mechanical linkage with leakage tripping device, make
Mechan-amplifier mechanism drives switch mechanism movement.Therefore leakage tripping device species divides clapper-type and release type two kinds of forms.But
The structure of existing electrical apparatus release is complex, and easily by strong magnetic disturbance；Stability is poor, and service life is not also high.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of multifunction structure type straight push-and-pull rod-type electrical apparatus release, no
It is only simple in construction, versatile；And it is widely used, stability is good.
Technical scheme is used by the utility model solves its technical problem：A kind of straight push-and-pull rod-type of multifunction structure type
Electrical apparatus release, including shell and cover plate, described enclosure side are provided with coil, and coil is fixedly connected on by coil rack
In shell；Opposite side is provided with magnet steel, magnet steel top connecting contact pin；Described coil is connected with magnet steel by static iron core, static iron core
It is connected with dynamic iron core；Stage clip is provided between dynamic iron core and static iron core；Lever is additionally provided with described shell；Described lever
One end cylinder lever connecting rod one end；The other end of pull bar extends housing exterior；The other end connection dynamic iron core of described lever.
Further, in order to simplify assembly technology, dynamic iron core described in the utility model and static iron core are cylindrical shape；
Dynamic iron core and static iron core surface contact portion air-gap-free；Described dynamic iron core forms direct acting striking structure with static iron core.
Further say, in order to be failed by any strong magnetic disturbance, and increase the stability of product, this practicality is new
Magnet steel described in type is SmCo magnet steel；Described enclosure is additionally provided with the magnetic-type colloid as auxiliary magnetic source.
Further say, its intermediate part described in the utility model is provided with circular hole；Axle is provided with the shell；Thick stick
Bar is placed on axle by circular hole and along the outer circular-rotation of axle.
The beneficial effects of the utility model are：Assembly technology is simple, has both eliminated clearance of the armature in armature support, has carried
High reseting precision, reduces movable quantity number of parts inside electrical apparatus release and reduces caused by multi-pass operation with simplifying effect again
Secondary pollution, stability is set preferably to be ensured, operating life improves；By increasing pull bar, lever changes thrust output
For pulling force, and power is amplified.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of preferred embodiment of the present utility model；
In figure：1st, shell；2nd, cover plate；3rd, coil rack；4th, dynamic iron core；5th, static iron core；6th, stage clip；7th, magnet steel；8th, lever；
9th, pull bar；10th, axle；11st, contact pin；12nd, lead.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing and preferred embodiment.These accompanying drawings are letter
The schematic diagram of change, only illustrates basic structure of the present utility model in a schematic way, thus its only show it is relevant with the utility model
Composition.
The straight push-and-pull rod-type electrical apparatus release of multifunction structure type as shown in Figure 1, by shell 1, cover plate 2, coil rack 3, dynamic iron
Core 4, static iron core 5, stage clip 6, magnet steel 7, lever 8, pull bar 9, axle 10, contact pin 11, lead 12 form；Enclosure side sets line
Circle, coil are fixedly connected in shell by coil rack；Opposite side sets magnet steel, magnet steel top connecting contact pin；Coil and magnetic
Steel is connected by static iron core, static iron core connection dynamic iron core；Stage clip is set between dynamic iron core and static iron core；Its intermediate part is provided with
Circular hole；Axle is provided with the shell；Lever is placed on axle by circular hole and along the outer circular-rotation of axle.One end of lever connects
Connect one end of pull bar；The other end of pull bar extends housing exterior；The other end connection dynamic iron core of lever.
Lever, pull bar and axle composition mechanical lever, are changed into pulling force, while power is put by electrical apparatus release thrust output
Greatly, simple in construction, having stable behavior is reliable；
Dynamic iron core and static iron core are cylindrical shape；Direct acting strike form is formed, armature had so both been eliminated and has been supported in armature
In clearance, improve reseting precision, reduce movable quantity number of parts inside electrical apparatus release again and simplify assembly technology, and can
The secondary pollution caused by multi-pass operation is efficiently reduced, stability is preferably ensured, especially in magnetic force, size magnetic
The adjustable range of power is now in leading, is even more that reached can be beyond 250g output action (small-signal in terms of output force value
Driving).Dynamic iron core discharges after anti-magnetized coil leads to electric current, promotes lever.
In order to be failed by any strong magnetic disturbance, and increase the stability of product, magnet steel described in the utility model
For SmCo magnet steel；Described enclosure is additionally provided with the magnetic-type colloid as auxiliary magnetic source.
Simply specific embodiment of the present utility model described in description above, various illustrations are not to this practicality
New 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 embodiment stated is made an amendment or deformed, without departing from the spirit and scope of utility model.
