Abstract
The invention relates to a self-bonding mica tape lapped wire with an improved structure, which belongs to the technical field of motor accessories and comprises a conductor and an insulator combined outside the conductor. The insulator is a first mica tape wrapped outside the conductor, or a film and a first mica tape which are sequentially wrapped outside the conductor, or an encapsulation layer sintered or combined outside the conductor by heat sealing and the first mica tape which is wrapped outside the encapsulation layer, or a second mica tape layer and the first mica tape which are sequentially wrapped outside the conductor. The self-bonding mica tape lapped wire with an improved structure is characterized in that the surface of one side of the first mica tape facing outwards is combined with a self-bonding layer. As the first mica tape combined with the self-bonding layer on the surface of one side thereof, the self-bonding mica tape lapped wire with an improved structure has perfect self-bonding so as to be beneficial for the trimming of coils; and as impregnating varnish is unnecessary during production of electromagnetic wires, the influence on the environment can be avoided and the manufacturing steps can be reduced.
Description
Technical field
The invention belongs to technical field of motor accessories, be specifically related to a kind of self-adhesive mica tape lapped wire that improves structure.
Background technology
The structure of the mica tape lapped wire in the prior art roughly has following several: the one, and wrapped polyimide film or wrapped polyester film outside flat conductor, wrapped mica tape outside polyimide film or polyester film again such as copper or copper cover aluminum.The mica tape lapped wire of this structure is not owing to have the self-adhesion performance, thereby in use, is unfavorable for the coil shaping, gives to install and use and causes difficulty; The 2nd, wrapped polyimide film, polyester film or mica tape outside the flat conductor of copper or copper cover aluminum, and then wrapped outside mica tape, then wrapped individual layer or double glazing silk outside mica tape, and dipping lacquer, online top layer adds soaks the self-adhesion lacquer, perhaps directly that mica tape is wrapped outside flat conductor, adds at mica tape and double-bags or the single-glass silk, dipping lacquer again adds on the top layer and to soak the self-adhesion lacquer.A kind of drawback of structure before the mica tape lapped wire of this structure can be eliminated, because after adding bag glass fiber dipping lacquer, can make it possess tack, yet dipping lacquer not only causes the pollution to environment, and causing the increase of used raw and auxiliary material, the spirit of environment-friendly type, economizing type and the energy-saving economy of endeavouring to advocate with the present whole society is runed counter to.
About having the self-adhesive mica tape lapped wire, existing being seen in Chinese patent literature, recommended " tack double glass fiber bag polyimide film and the wrapped copper clad aluminum flat wire of mica tape " as Granted publication CN201413678Y, it is successively in conjunction with polyimide film, mica tape, the first resin enamelled coating, double glass fiber, the second insulating resin enamelled coating and self-adhesion enamelled coating outside copper clad aluminum flat wire; And for example CN201413681Y provides " tack single glass fibre bag polyimide film and the wrapped copper strap wire of mica tape ", and the difference of this patent and last patent only is that the former is a copper clad aluminum flat wire, and this patent is a copper strap wire; CN201413680Y discloses " tack double glass fiber bag polyimide film and the wrapped flat aluminium wire of mica tape " for another example, and the difference of this patent and CN201413678Y is that the former is a copper clad aluminum flat wire, and the latter is a flat aluminium wire.
There is the layer of structure complexity in above-mentioned three patents, diminishes environmental protection and raw material consumption and irrational shortcoming in process of production, so the applicant thinks and be necessary to be improved that technical scheme described below produces under this background.
Summary of the invention
Task of the present invention is to provide a kind of process procedure that helps to reduce in the processing, helps avoiding causing in the course of processing to environmental impact and is of value to the use of saving raw and auxiliary material and has good tack and use the self-adhesive mica tape lapped wire that makes things convenient for the improvement structure of coil shaping.
Task of the present invention is finished like this, a kind of self-adhesive mica tape lapped wire that improves structure, comprise conductor and be combined in the outer insulator of conductor, this insulator be wrapped outside described conductor first mica tape, successively wrapped outside conductor film and first mica tape, sintering or heat-seal bond outside conductor encapsulated layer and outside encapsulated layer wrapped first mica tape or wrapped successively second mica tape and first mica tape outside conductor, it is characterized in that: described first mica tape side surface outward is combined with self-adhesive layer.
In a specific embodiment of the present invention, described conductor is flat copper conductor, flat copper cladding aluminum conductor or flat aluminium conductor.
In another specific embodiment of the present invention, the thickness of described conductor is 0.8-5.6mm, and width is 2-16mm.
In another specific embodiment of the present invention, described film is polyimide film or polyester film, and the thickness of film is 0.025-0.05mm.
In another specific embodiment of the present invention, described second mica tape is single face polyester reinforcement mica tape or two-sided polyester reinforcement mica tape, and thickness is 0.07-0.09mm.
Also have in the specific embodiment of the present invention, described encapsulated layer is the wrapped polyimide film of laminated film that the single or double of sinter bonded outside described conductor is coated with fluorine 46.
More of the present invention and in specific embodiment, described encapsulated layer is the compound corona-resistant polyimide film that the single or double of heat-seal bond outside described conductor is coated with fluorine 46.
In of the present invention and then specific embodiment, the wrapped mode of described first mica tape is that opposite joint is wrapped or overlapping wrapped, and described overlapping wrapped packet stack rate is 33-66%.
Of the present invention again more and in specific embodiment, the thickness of described first mica tape is 0.07-0.09mm.
In again of the present invention and then specific embodiment, described self-adhesive layer is a hot melt adhesive layer.
Technical scheme provided by the invention has been owing to adopted first mica tape that is combined with self-adhesive layer at a side surface, therefore has desirable tack and helps the shaping of coil; Owing in the production process of electromagnetic wire, need not dipping lacquer, thereby can avoid environment is impacted and can reduce processing step in the manufacturing process.
