Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In the description of this specification, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, identical embodiment or example are not necessarily referred to the schematic representation of above-mentioned term.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.
In description of the present utility model, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, such as, can be mechanical connection or electrical connection, also can be the connection of two element internals, can be directly be connected, also indirectly can be connected by intermediary, for the ordinary skill in the art, the concrete meaning of above-mentioned term can be understood as the case may be.
As shown in Figure 1, be the structural representation of the winding coil circle of the utility model preferred embodiment.Winding coil of the present utility model is made up of metal carbonyl conducting layer 1, first insulating barrier 2, second insulating barrier 3 and adhesive layer 4.First insulating barrier 2 is coated on metal carbonyl conducting layer 1 appearance, and the second insulating barrier 3 is coated on the appearance of the first insulating barrier 2, and adhesive layer 4 is coated on the appearance of the second insulating barrier 3.
Metal carbonyl conducting layer 1 is preferably the high metal material of conductivity, such as copper.Metal carbonyl conducting layer 1 plays a part conduction.According to the actual needs of products application, concrete metal material can be selected.
First insulating barrier 2 is PBT material, and the second insulating barrier 3 is PET material.The better mechanical property of PBT material, namely intensity high, fatigue durability, dimensionally stable, creep are also little (also rarely changing under hot conditions); Ageing-resistant performance is good, and the Undterwriter's Laboratory temperature index after namely strengthening reaches 120 ~ 140 DEG C; Solvent-resisting is better, i.e. unstressed cracking in solvent.What is more important, electrical insulating property is comparatively excellent, and namely moist, high temperature also can keep electric performance stablity.PET material tool has the following advantages: 1. have good mechanical property, and impact strength is 3 ~ 5 times of other films, and folding resistance is good; 2. oil resistant, resistance to fat, resistance to diluted acid, diluted alkaline, resistance to most of solvent; 3. there is excellent high-and low-temperature resistance performance, can in 120 DEG C of temperature ranges Long-Time Service, short-period used can resistance to 150 DEG C of high temperature, can resistance to-70 DEG C of low temperature, and very little to its mechanical impact during high and low temperature; 4. gas and vapor permeability low, namely have excellent choke, water, oil and peculiar smell performance.5. transparency is high, can shielding of ultraviolet, and glossiness is good.Adopt the first insulating barrier 2 of PBT material and the second insulating barrier 3 of PET material can significantly improve folding resistance and the water proofing property of winding coil, PBT material and PET material due to construction unit similar, thus both have good compatibility.The thickness of the first insulating barrier 2 can be 80 ~ 150 μm, and the thickness of the second insulating barrier 3 can be 100 ~ 300 μm.
