Abstract
The utility model discloses a self-adhesive mica tape lapped wire, which belongs to the technical field of motor accessories. The self-adhesive mica tape lapped wire comprises a conductor and an insulator which is combined outside the conductor, wherein the insulator is a mica tape which is lapped outside the conductor. The lapped wire is characterized in that: the outward side surface of the mica tape in a lapping state is combined with a self-adhesive layer. In the technical scheme, because the mica tape of which one side surface is combined with the self-adhesive layer is adopted, ideal self-adhesion is achieved to contribute to shaping a coil; and because paint dipping is not needed during the production of an electromagnetic wire, the influence on the environment can be avoided and process steps in a manufacturing process can be reduced.
Description
Technical field
The utility model belongs to technical field of motor accessories, is specifically related to a kind of self-adhesion mica tape winding wire.
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, aluminium 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, aluminium 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 utility model 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 and saves raw and auxiliary material and have good tack and use convenient self-adhesion mica tape winding wire to the coil shaping.
Task of the present utility model is finished like this, a kind of self-adhesion mica tape winding wire, comprise conductor and be combined in the outer insulator of conductor, described insulator is wrapped mica tape outside described conductor, it is characterized in that: described mica tape outward side surface under wrapped state is combined with self-adhesive layer.
In a specific embodiment of the present utility model, described conductor is flat copper conductor, flat copper cladding aluminum conductor or flat aluminium conductor.
In another specific embodiment of the present utility model, the thickness of described conductor is 0.8-5.6mm, and width is 2-16mm.
In another specific embodiment of the present utility model, the wrapped mode of described mica tape is that opposite joint is wrapped or overlapping wrapped.
In another specific embodiment of the present utility model, described overlapping wrapped be 33-66% for taking 2mm-3mm or packet stack rate.
Also have in the specific embodiment of the present utility model, the thickness of described mica tape is 0.07-0.09mm.
More of the present utility model and in specific embodiment, described self-adhesive layer is a hot melt adhesive layer.
The technical scheme that the utility model provides has been owing to adopted the 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.
