Background technique

Coil is often referred to wire winding in a ring, and the most common coil application has: motor, inductance, transformer and annular Antenna etc..Coil in circuit refers to inductor.It is that guide line is wound up one by one, conducting wire insulate each other, and insulate Pipe can be hollow, also may include iron core or powder core, abbreviation inductance；But existing coil is relatively easy to voltage occur to hit Phenomenon is worn, it is dangerous.

So how to design a kind of anti-breakdown Polymer-filled, becoming us will currently be solved the problems, such as.

Utility model content

It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of anti-breakdown Polymer-filled Problem.

To achieve the above object, the utility model provides the following technical solutions: a kind of anti-breakdown Polymer-filled, including device Ontology, described device ontology are made of iron core, frame and coil module, and the frame is specially that " 2 " are a, the two frame difference The both ends of the iron core are fixed at, the coil module is set on the iron core, and between two frames, institute It states coil module to be made of coil, epoxy resin layer and copper foil, is sufficiently filled with the epoxy between every two layers of coil Resin layer is also sufficiently filled with the epoxy resin layer, the copper foil described in the last layer between coil and the copper foil It is wrapped in outside coil described in the last layer, and described device ontology is enclosed with encapsulating glue-line, the side of the frame is equipped with connects Wire pin, and the terminals of the wiring pin are pierced by the encapsulating glue-line.

Further, the coil is equipped with lead wire outlet, and is connected between the lead wire outlet and the wiring pin by conducting wire It connects.

Further, the frame is made of insulating material.

Further, the distance between the frame and the coil module are 2cm.

Further, the encapsulating glue-line with a thickness of 1cm.

Further, epoxy resin layer is also sufficiently filled between the coil and the iron core.

Compared with prior art, the utility model has the beneficial effects that this kind of anti-breakdown Polymer-filled by iron core with Increase epoxy resin layer resistant to high temperature between coil, further to enhance the insulating properties between iron core and coil, avoid leaking Electric current is exceeded, and the insulation that epoxy resin layer comes between intensifier coil is in addition also sufficiently filled between every two layers of coil, is prevented Voltage breakdown wraps up copper foil outside the coil of the last layer, and is wrapped up with casting glue, prevents air humidity to bring significantly Influence, further prevent breakdown bring risk, certain distance will be kept between wiring pin and coil, and have ring Oxygen resin layer and casting glue insulate, and improve insulation effect.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of anti-breakdown Polymer-filled, including device sheet Body 1, described device ontology 1 are made of iron core 2, frame 3 and coil module 4, and the frame 3 is specially that " 2 " are a, two frames 3 are respectively fixedly disposed at the both ends of the iron core 2, and the coil module 4 is set on the iron core 2, and are located at two frames Between frame 3, the coil module 4 is made of coil 5, epoxy resin layer 6 and copper foil 7, between every two layers of coil 5 sufficiently Filled with the epoxy resin layer 6, the epoxy is also sufficiently filled between coil 5 and the copper foil 7 described in the last layer Resin layer 6, the copper foil 7 is wrapped in outside coil 5 described in the last layer, and described device ontology 1 is enclosed with encapsulating glue-line 8, The side of the frame 3 is equipped with wiring pin 10, and the terminals of the wiring pin 10 are pierced by the encapsulating glue-line 8.

Further, the coil 5 is equipped with lead wire outlet 9, and by leading between the lead wire outlet 9 and the wiring pin 10 Line connection, prevents insulation breakdown.

Further, the frame 3 is made of insulating material, and reduces cost, improves safety.

Further, the distance between the frame 3 and the coil module 4 are 2cm, make the insulation distance of winding wire Increase, prevents insulation breakdown.

Further, the encapsulating glue-line 8 with a thickness of 1cm, improve insulation thickness, reduce risk breakdown.

Further, it is also sufficiently filled with epoxy resin layer 6 between the coil 5 and the iron core 2, utilizes epoxy resin Characteristic resistant to high temperature reduces the insulation damages between the coil 5 and the iron core 2, avoids Leakage Current exceeded.
