Description
Technical field
The present invention relates to electronic component technology field, more particularly, to a kind of dry-type air-core reactor.
Background technology
At present, the encapsulation of dry-type air-core reactor is carried out using by the impregnated glass fibre of epoxy resin to coil mostly
Encapsulating insulation, is completed by hot setting again afterwards.In this way, the outer surface insulating barrier formed is than relatively thin, it is easily damaged, and
Surface is more coarse, not attractive in appearance enough.
The content of the invention
For above-mentioned the shortcomings of the prior art, it is an object of the invention to provide a kind of dry-type air-core reactor, and it has
Be hardly damaged, it is more attractive in appearance the characteristics of.
To achieve these goals, the technical solution adopted in the present invention is：Dry-type air-core reactor, including 2 inductance,
Each inductance includes：Support frame, 2 strands of copper coils and 2 strands of copper coils counterclockwise clockwise inside support frame, positioned at branch
Support top and the first outlet terminal of the outer end for connecting 2 strands of copper coils clockwise and positioned at support frame top and it is used for
The second outlet terminal of the outer end of 2 strands of copper coils counterclockwise is connected, meanwhile, 2 first outlet terminals are linked together, are somebody's turn to do
2 the second outlet terminals link together, and 2 support frames are close together side by side, copper coil and the copper counterclockwise clockwise
Coil outer surface is equipped with epoxy resin dipping layer, and is sequentially provided with steel mesh layer, aluminium on the outer surface of 2 support frames from the inside to the outside
Flaggy and engineering thermosetting plastic injection molded layers.
The inner end of the 2 strands of copper coils clockwise and 2 strands of copper coils counterclockwise that are under the jurisdiction of same inductance passes through a copper sheathing
It is locked.
After said structure, the invention has the advantages that compared with the prior art,：It is hardly damaged, it is more attractive in appearance.
The copper cash of the dry-type air-core reactor of the present invention first passes through epoxy resin dipping, then passes through engineering thermosetting outside support frame again
Plastics are molded, and not only increase the mechanical strength of reactor, and make reactor any surface finish attractive in appearance, be then hardly damaged,
It is more attractive in appearance.Meanwhile the installation of such reactor is more convenient, electric wire connect safe and stable property preferably, rapid heat dissipation, ensure that
Operate steadily and the good linearity of inductance value.And reactor noise, loss, the leakage field after so handling are smaller.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the front view of the dry-type air-core reactor of embodiments of the invention；
Fig. 2 is the front view of the internal structure of the dry-type air-core reactor of embodiments of the invention；
Fig. 3 is Fig. 1 top view；
Fig. 4 is the partial cross-sectional top view (being exaggerated relative to Fig. 1) of the support frame of the present invention.
In figure：
10th, support frame；
21st, copper coil clockwise, 22, copper coil counterclockwise；
31st, the first outlet terminal, the 32, second outlet terminal；
41st, steel mesh layer, 42, aluminum layer, 43, engineering thermosetting plastic injection molded layers；
50th, copper sheathing.
Embodiment
Embodiment, as shown in Fig. 1 to Fig. 3：Dry-type air-core reactor, including 2 inductance.Each inductance includes：Support
Frame 10,2 strands of copper coils 21 clockwise and 2 strands of copper coils 22 counterclockwise inside support frame 10, positioned at the top of support frame 10
And for connect 2 strands of copper coils 21 clockwise outer end the first outlet terminal 31 and positioned at the top of support frame 10 and be used for connect
Connect the second outlet terminal 32 of the outer end of 2 strands of copper coils 22 counterclockwise.That is, the copper cash in each inductance shares 4 strands.
Meanwhile this 2 the first outlet terminals 31 link together, this 2 the second outlet terminals 32 link together, 2 support frames
10 are close together side by side.Certainly, the first outlet terminal 31 and the inevitable outside for occuping reactor of the second outlet terminal 32.
Further say：
The outer surface of copper coil 21 and copper coil counterclockwise 22 clockwise is equipped with epoxy resin dipping layer.That is,
4 strands of copper cash of each inductance are impregnated in the epoxy.Set successively from the inside to the outside on the outer surface of 2 support frames 10
There are steel mesh layer 41, aluminum layer 42 and engineering thermosetting plastic injection molded layers 43.Engineering thermosetting plastic injection molded layers 43 are by engineering thermosetting plastic
Formed after being molded as raw material.Certainly, the first outlet terminal 31 and the outside of the second outlet terminal 32 do not have engineering thermosetting
Plastic injection layer 43.So, the mechanical strength of the dry-type air-core reactor, heat dispersion, leakproof magnetic property are improved, and makes electricity
Anti- device surface is more bright and clean and attractive in appearance.
Optimization：
It is under the jurisdiction of 2 strands of copper coils 21 clockwise of same inductance and the inner end of 2 strands of copper coils 22 counterclockwise by one
Copper sheathing 50 is locked.That is, the inner of 4 copper cash of same inductance is formed by the stirrup of copper sheathing 50.Certainly, 4 strands of copper cash
The inner between mutually insulated.So, the stability of the dry-type air-core reactor structure is further increased.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, every utilization
The equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
